The Most Valuable Code Is the Code You Should Not Write

By Jasper Sprengers

CORE

In my previous articles, I wrote about maximizing your competitive advantage as a human software developer against encroaching AI. I illustrated why it will always be hard to write useful software, with or without machine assistance. One thing I didn’t address is how all this may just take away the joy of writing code. I don’t mean your lovingly crafted Open-Source projects. Please continue doing that. I mean the enterprise behemoths we write and maintain for a paycheck. To recap the discussion about efficiency and effectiveness: if AI can write that code similarly well (right now, it's still an if), it will nearly always be cheaper than hiring you to do the job, as well as more reliable (no sick leave) and more flexible (unlimited overtime/no onboarding required). Sorry about that. Mechanization relieves us of manual work that is either too strenuous, dangerous, or dirty. No medieval peasant liked pulling a cart. So, we used horses and other animals. We invented tools and machines, and not just for replacing muscles. Granted, while some mental labor can be mind-numbingly boring, most of it isn’t especially dangerous or dirty. There are uncomfortable exceptions, like social media moderation, but much of it is challenging and good for your brain. So why should we let AI do something that humans already like to do and do well, like writing screenplays or writing songs? A cynical bean counter would argue that it makes no sense to do anything by hand if the machine can deliver acceptable quality cheaper. There’s a niche market for hand-knit garments, but not enough knitters to keep the world clothed. If you have a good employer, they’ll care about your health and well-being, but their prime concern is not to ensure you a non-stop joy of coding experience, especially not when AI can eventually produce it at a fraction of the cost. Code is a means to create value, but it is also a liability. It’s expensive to create and maintain if we can realize the same value with less (or no) code, so much the better. I don’t know when skills in traditional coding languages (with classes, types, variables, and control structures) will be obsolete, but I predict it will be well before my retirement. Until that singularity comes, traditional coding prowess (brain teasers like the Advent of code) will increasingly become another mental challenge that computers can do better. We practice it for fun or in competition with other people. Like chess and go. Meanwhile, please keep this stuff out of technical interviews. It doesn’t matter anymore, and I don’t believe it ever did. Knowing how to write a shoddy implementation of an array list or a merge sort on a whiteboard tells you what, exactly? That you can re-invent the wheel. Congratulations, but I believe a more valuable skill for a senior developer is knowing when not to code. That’s why I present the no-code interview, based on a coding challenge where the wisest decision should be to leave well alone. It could go like this. The No-Code Interview Interviewer: “Suppose we have a stand-alone application written in Java 6 with a very basic Swing GUI that reads an XML file, transforms, and enriches the data by doing several database lookups and produces an Excel report. It was built and maintained by a developer who left us a year ago. Our senior architect had a look at the code and decided that quality was seriously below par. It’s the usual spaghetti, with hardly any unit tests. How would you go about improving it to bring it up to a good standard?” Applicant: “Before I look at the code base, I would first like to get a feeling of how urgent and how important this refactor is. Because they’re two different concerns.” Interviewer: “How so?” Applicant: “Well, my annual tax return is very important, but since it’s not due for another six months, it’s not urgent. Then again, if I want to get a theater ticket for tonight, that’s urgent but not very important. So, how important is this tool to the organization? How much benefit does it give, and how much damage can it do? What happens if users can’t access the tool for an hour? How about a day, a week? What if it produces wrong data? How many users rely on this? How often does it run? And with urgency, I mean, how long can we afford to postpone the work? Do the end users have a problem right now? Does it perform reliably in production? Have there been any incidents with it recently? How frequent are requests for change? How stable are the input and output specifications? Does it rely on any legacy technology that is soon becoming obsolete and needs to be upgraded? Or does company policy require it?” Interviewer: “Very good questions. Let me summarize: the application is used twice a year to produce the input for an in-house questionnaire. The incoming file is a dump from payroll and is very stable. Feature requests come in three/four times a year. I believe it’s written in Java 6, and it runs on a developer’s machine.” Applicant: “About these feature requests: how awkward is it to make changes?” Interviewer: “Apparently, it’s a big hassle. We had two separate developers doing minor changes recently, and they both complained that they could have been done in a fraction of the time had the code been more readable.” Applicant: “Were these feature requests similar?” Interviewer: “Yes. It’s mostly adding or removing a column to the output.” Applicant: “And yet developer number two still complained that it took too long. Is it fair to assume that developer number one did not document its process and didn’t do any refactoring? Interviewer: Touché Applicant: “That's your first small win already. But I get the impression that a full overhaul is neither important nor urgent, so I would not advise it. The effort should go towards making incremental changes less painful. Refactor with a focus on that.” Interviewer: “I like your answers so far. Now, suppose I told you the tool is very heavily used, and errors are unacceptable. Say we’re a bank, and it calculates a percentage for a loan offer. An error could mean we over- or undercharge customers to the tune of millions. Feature requests are frequent and varied, and the company demands that we bring it up to standard. How would you set about it?” Applicant: “How about unit-test coverage?” Interviewer: “Less than 20%” Applicant: “If an employer were that cavalier about such a business-critical component, I don’t think I’d want to work for them. So, I’m glad it’s only hypothetical. We need to tackle test coverage before we touch any sources. The risk of regression is too great if you start refactoring without it. Making detailed unit tests is probably not feasible if everything is tightly coupled. Let’s start with a single black-box component test. The code base is fragile, so with every change, we should ensure we haven’t broken anything. Create a representative XML input file and a containerized database. Run the application once and take the Excel file it produces as a baseline. Now, whenever the component test runs the application with the same input and database state, the output should match the reference file bit by bit (unless it relies somewhere on the current date/time). Now, you can start decoupling file I/O and database access from the business logic and create proper unit tests without the risk of breaking anything. But since you’re adding tests as an afterthought, forget about TDD orthodoxy. The benefit of writing tests in tandem with production code is already gone. You’ll probably find that your single component test already boosted coverage by 30 percentage points.” Interviewer: “My last question. Don’t you like good code?” Applicant: “Of course I do. But I like useful software better. I’m sure there are great applications with terribly unclean source code under the hood. Same here. The code may hurt our sense of craftsmanship, but it’s not broken unless we have an acute or imminent problem. And that can happen after a well-intentioned improvement. Make these improvements only in response to actual feature requests. Timebox your efforts, in that case. It’s tempting to bring an F up to an A, but it’s rarely good business sense.” More

A Guide To Growing Your Technical Knowledge Portfolio

“An investment in knowledge always pays the best interest." — Benjamin Franklin The wise words of Benjamin Franklin, the trailblazer of financial and intellectual wisdom. As a leader, I'm frequently asked this question: How do you stay tech-savvy with a jam-packed schedule? Allow me to share insights and suggestions drawn from my experience and expertise. Your knowledge is like that fancy cheese in your fridge. It's great, it's valuable, but it has an expiration date. Just like your cheese gets all moldy and inedible, your knowledge can become outdated faster than the latest viral internet challenge. In today's tech-driven world, things change faster than you can say "Java." So, what's a tech-savvy pro like you to do? Well, you've got to manage your "knowledge portfolio." Think of it like your stock market investments, but instead of stocks, it's all the cool stuff you know about programming and tech. Invest Regularly Just like you put money into your savings account every month, invest in your brain regularly. Learn new stuff, even if it's just a smidge at a time. Make it a habit, like brushing your teeth (but way more exciting). Diversify Don't put all your eggs in one basket. You need to know more than just one trick. It's like being a master chef who can whip up a killer lasagna and make sushi that's to die for. The more you know, the more valuable you become. Manage Risk Tech is a bit like the Wild West. Some things are safe bets. Others are like wild stallions you're trying to tame. Don't go all in on risky stuff, but don't play it too safe either. Balance is key. Buy Low, Sell High Have you ever heard of investing in Bitcoin when it was just a digital blip on the radar? Learning a new, unheard-of technology can be just like that. Risky at first, but the payoff? Oh, it can be sweet. Review and Rebalance Remember that awesome app you were excited about last month? Well, it might be as cool as a flip phone now. Your knowledge needs a spring cleaning, too. Don't let it gather dust. Now, for the fun part — setting goals! Learning new languages, reading tech books, and attending courses or meetups. It's like collecting shiny Pokémon. You gotta catch 'em all, or in your case, learn 'em all. And don't forget the non-technical stuff. Computers are just tools, and they're used by real people. You work with them, for them, and occasionally get pranked by them. So, get some "soft skills" under your belt. They're as valuable as knowing your Java from your JavaScript. Example goals could be: Learn at least one new language every year Read a technical book each month. With easy access to audiobooks and podcasts on our mobile, this should be reasonable to achieve. Participate in local user groups and meetups once a fortnight Lastly, think critically. Just because someone's yelling, "This is the best thing ever!" doesn't mean it's your best thing ever. Ask questions like a curious four-year-old. Dive deep and find out who benefits from all this tech hype. So, my dear tech-savvy friend, keep your knowledge portfolio as diverse as a buffet, manage it like a financial genius, and stay curious like a kid in a candy store. Your brain is your best investment, and it's time to make it rich in knowledge!

Symfony certification is not only valued by potential employers but also within the software industry. It stands as a respected mark of honor that can lead to increased visibility and recognition as a skilled and dedicated engineer. Understanding what lies ahead is crucial for proper preparation and success. Next, explore what you’ll encounter as you want to pass the Symfony certification exam. What To Expect Understanding what to expect when studying for Symfony certification is an essential part of the process. It allows you to prepare effectively, set clear goals, and approach the certification journey with confidence. Whether you’re aiming to become a Symfony Certified Developer, the road to certification involves careful study, practical experience, and a profound understanding of Symfony’s core concepts and best practices. In my case, it requires a three-month period during which I dedicate 1.5 hours of study each day, along with daily testing through Sensiolabs University. The exam format consists of multiple-choice, single-choice, and yes/no questions. It offers two different certification levels. These include the Advanced Developer and Expert Developer certifications. Also, It covers 15 topics related to PHP, HTTP, and the framework. You can expect questions related to Symfony’s core concepts, such as routing, controllers, DI, and the security component. Each concept is associated with a specific number of questions that are organized in the exam. For instance, the exam includes a categorized breakdown, such as five questions related to Twig and four questions on routing, among others. This structure allows for easy navigation to specific topics and questions if you have any uncertainties. In addition to theoretical knowledge, a profound understanding of best practices and the code structure in Symfony development is essential. When referring to “code,” this means having knowledge of the expected return types, arguments, and interfaces for each topic. This in-depth comprehension of the code is vital for success in the certification process. A sample question would be: Which method must implement a TranslationLoaderthat implements Symfony\Component\Translation\Loader\LoaderInterface? public function load(string $resource, string $locale, string $domain ='messages'):MessageCatalogue; public function load(string $resource, $locale = 'en', $domain = 'messages'): MessageCatalogue; public function load(mixed $resource, string $locale, string $domain): MessageCatalogue; public function load(mixed $resource, string $locale, string $domain = 'messages'): MessageCatalogue; Preparing for Symfony certification requires a comprehensive approach. Symfony provides a wealth of study resources to aid in your preparation. These resources include the official Symfony certification exam guide, which outlines the exam’s content, format, and expectations. Additionally, you can access Symfony documentation, a list of topics with details made by Thomas Berends, online courses, tutorials, and practice questions in Sensiolabs University to help you prepare thoroughly. For PHP, you’ll want to focus on mastering key PHP concepts and features. Start by revisiting fundamental PHP concepts. Ensure you have a solid understanding of variables, data types, operators, and basic language syntax. This knowledge provides a strong foundation for more advanced topics. The most important part is OOP, dive deep into object-oriented programming in PHP. Understand how to create classes, objects, and methods. Explore concepts like encapsulation, inheritance, traits, etc. Consider that you may encounter questions regarding the new features introduced in different PHP versions. These questions might require you to identify the version in which a specific feature was added or even the birth date of PHP. Here is a sample question? Is this code valid private const bar = 'foo';? Yes, as of PHP 5.6. Yes, as of PHP 6.0. Yes, as of PHP 7.1. No, it’s not valid. Yes, as of PHP 7.0. To excel in the HTTP-related sections of the exam, focus on mastering the essentials of web communication. Begin by comprehending the fundamental principles of client/server interaction in web development. Grasp the concept of how clients and servers communicate through the request-response model. Read common HTTP status codes and their meanings. These codes play a pivotal role in indicating the outcome of client-server interactions — also, delve into the components of HTTP requests and responses. Understand the structure of request headers, request bodies, response headers, and response bodies. Besides, Learn the significance of cookies in maintaining user states and caching in optimizing client-server interactions. Understand how they impact web development practices. Such as validation, expiration, and proxy. A sample question would be: What is the HTTP Responsestructure? Status-Line Headers Message-body Status-Line Headers CRLF Message-body Status-Line CRLF Headers CRLF CRLF Message-body Status-Line CRLF Headers CRLF Message-body Besides reading official documents, my experience with Sensiolabs University was excellent. This platform permits you to attempt a daily test comprising 20 questions covering a variety of topics. It is beneficial for understanding the format and creation of the main exam questions. Additionally, it provides a visual representation of your knowledge through charts and detailed feedback, allowing you to identify areas where you may need to focus more effort. Getting ready for certification is not solely about theoretical knowledge. Practical experience plays a pivotal role in your success. Therefore, while you study the framework’s documentation, it’s equally important to practice building web applications with Symfony. Real-world experience provides you with a practical foundation that is invaluable when answering the practical exercises in the certification exam. Regarding the question difficulty level, it’s worth noting that the questions encompass a mix of both easy and challenging ones. However, they can be quite tricky, necessitating a thorough review of the documentation. You should avoid underestimating any specific topic, as all the information is clearly presented in the official preparation list. Underestimating a topic may result in regrets during the actual exam. While one might claim that having worked with Symfony for over three years means they know everything and require no further study for a specific topic, the reality is that success remains elusive without enough studying. Symfony certifications typically have a validity period, after which you may need to renew your certification. Renewal often involves taking a more advanced exam to ensure that you stay up-to-date with the latest Symfony developments. This aspect reflects the ever-evolving nature of web development and ensures that certified developers continue to meet industry standards. Real-Life Stories: From Symfony Enthusiast to Symfony Certified Engineer While the path to becoming a Symfony Certified Engineer may seem like a rigorous journey, it’s essential to recognize that many individuals from diverse backgrounds have successfully achieved this milestone. These real-life stories serve as inspiring examples of how dedication, hard work, and a passion for Symfony can lead to remarkable career transformations. I’m Alireza, a software craftsman who started their journey eight years ago with a deep appreciation for Symfony. My story is a testament to the power of continuous learning and the profound impact that Symfony certification can have on one’s career. I started my journey with Symfony because I was really excited about programming. I already knew a lot about PHP and web stuff, and Symfony seemed like a great framework that matched what I wanted to do with my career. It started as a hobby, but it quickly became something I was very passionate about. When it was time to think about getting my Symfony certification, I didn’t shy away from the challenge. I made a detailed study plan, revisited all the topics I needed to learn, and practiced with sample questions. I was determined to learn everything I needed to know. During my study sessions, I took notes on paper and organized them by topic, which helped me study more effectively. I read the official Symfony documentation multiple times, and each time I found something new and added more notes. To make my preparation even better, I subscribed to SensioLabs University, which had a daily test with 20 questions on different topics. The great thing about this test was that it showed me the questions I got wrong before, and repeated some of them in new tests to make sure I really learned from my mistakes. After each test, instead of just giving me the correct answers, it pointed me to the Symfony documentation, where I could find the answers myself. It also gave me an overall score and told me which topics I needed to study more. In the beginning, my scores were around 7 or 8, but after months of studying for 1.5 hours every day, I was able to get a perfect score of 20/20. Besides the daily test, I could also access SymfonyCasts, which had tutorials to help me learn, especially when I didn’t understand a topic. On the day of the Symfony certification exam, I felt both confident and humble. I quickly reviewed my notes in the morning and took the test in the afternoon. And when the results came in, I had officially earned the title of Symfony Certified Engineer. The certification marked a significant turning point in their career. Doors that were once closed now swung open, offering exciting opportunities in web development. I’m not alone in this journey. Many Symfony enthusiasts have gone from novices to experts, with the Symfony certification serving as a beacon of their dedication and expertise. Keeping Your Symfony Certification Current: Staying Updated in a Fast-Changing System Once you’ve earned your Symfony certification, it’s essential to understand that the world of Symfony keeps changing. The framework evolves, new features are added, and best practices may shift. To ensure your certification remains relevant, you need to keep up with these changes. Symfony is like a living thing that keeps growing and improving. Imagine it’s a tree, and you’ve climbed it to get your certification. But the tree doesn’t stop growing, so you need to keep climbing to stay at the top. To stay current, follow these steps: Keep learning: Symfony releases new versions and updates with exciting features. Stay curious and explore these changes. Read the Symfony blog and official documentation regularly. Engage with the community: Join the Symfony community. It’s like a club of Symfony fans and experts. You can ask questions, share your knowledge, and learn from others. Attend events: Symfony events and conferences happen worldwide. They’re like big parties for Symfony lovers. You can attend to meet people, learn new things, and have fun. Practice and build: Keep working on Symfony projects. Just like a musician practices to get better, you need to keep using Symfony to stay sharp. Take More Tests: Symfony might release new certification exams. Just like in a video game, you need to level up by passing these exams. By doing these things, you’ll continue to grow in your Symfony skills and keep your certification valuable. It’s like staying on top of the tree and enjoying the view as it keeps growing.

The Journey of Becoming a Blockchain Developer

Blockchain solutions are becoming more popular, signaling a rising demand for professionals who develop these systems. Just six to eight years ago, the role of a blockchain developer was relatively obscure. Today, you can find these professionals networking in dedicated communities, actively engaging in forums, and scouring job sites for the most attractive employers. In this article, I will explore what it takes to become a blockchain developer. While cryptocurrencies remain the most popular application of blockchain technology, their significance in the digital sphere has vastly broadened. Today, blockchain plays a crucial role in enhancing digital security, such as thwarting DDoS attacks and hacking attempts, by bolstering data protection in cloud storage via decentralized networks. It also revolutionizes advertising by directly connecting goods and services with consumers, bypassing the need for intermediaries. In the entertainment sector, blockchain technology presents new avenues for safeguarding artists' copyrights. In finance, it fortifies the security protocols of banking transactions. A concept known as a Decentralized Autonomous Organization has emerged, functioning on blockchain principles. These are collective entities governed by their members, operating under a shared set of rules encoded into a digital document. Every decision within a DAO is a group consensus, achieved transparently through blockchain-facilitated voting via smart contracts. Notable examples of such entities are decentralized investment funds and crypto exchange platforms. This evolution signifies a shift in the perception of blockchain technology, from a tool tailored exclusively for cryptocurrencies to a versatile technology synonymous with distributed ledgers, operational transparency, and a means to establish a secure, trustworthy digital environment. Who Is a Blockchain Developer? Simply put, a blockchain developer is an expert who develops and refines applications based on blockchain technology. Their career can take various forms, such as specializing in smart contracts, core development, blockchain data analysis, or developing distributed applications. What Skills Are Required? Firstly, it is beneficial to have a solid educational foundation in computer science, including studies in mathematics, computer theory, information security, cryptography, and system architecture. If you are already a developer looking to pivot into blockchain, you are in a favorable position for this transition. Starting a career in blockchain requires proficiency in programming languages like Go, Solidity, Rust, or JavaScript. If you already have a couple of years of development experience, you can likely manage the transition into blockchain on your own in just a few months. It is crucial to recognize that different programming languages are used for various aspects, like server, front-end, or analytics, and others are specific to writing and examining smart contracts. A practical approach is to initiate your journey by crafting a few smart contracts. You can test these by launching them on a local network like Ganache or on official test networks (e.g., Ethereum's Goerli) and subsequently share your work on GitHub. Hard Skills for Aspiring Blockchain Developers Again, to become a blockchain developer faster, you need proficiency in programming (however, you do not need to be a full-stack expert; proficiency in one of the mentioned languages is enough), a good grasp of architecture, familiarity with the technologies that form the backbone of blockchain, and ideally, some hands-on experience in developing smart contracts. Here is a rundown of the key skills likely to come up in a job interview: Proficiency in JavaScript and Solidity (knowledge of C# is a bonus) is crucial for working with the Ethereum blockchain. Python is primarily for the Tezos blockchain platform. Competency in using protocols such as HTTPS, RPC, and gRPC. Practical understanding of how REST API principles are implemented. Familiarity with one well-known networks like Ethereum, TON, or Solana, which are vital for developing applications with decentralized data storage and managing cryptocurrencies. Experience in crafting smart contracts, particularly in the language suited for the chosen network, like Solidity for Ethereum. Skills in working with cryptographic tools and applying computer science and mathematical principles to encrypt data at the sending point and decrypt it at the receiving end. A foundational understanding of blockchain basics, including database and computer network management systems, which are crucial for the creation and maintenance of blockchain technology, and the ability to design network topologies. Knowledge of various data structures such as arrays, linked lists (both branched and linear), trees, etc. Companies typically do not specify the length of work experience required for blockchain positions. They recognize that the market has few professionals with years of experience in blockchain projects. As a result, they prioritize the actual competencies and skills of the candidates. Helpful Soft Skills What additional qualities are beneficial for you to thrive as a blockchain developer? While they share many similarities with typical developer skills, there are certain distinct aspects to consider. Key soft skills include: A strong inclination toward analytical thinking. A proactive mindset in learning new technologies. The ability to solve problems efficiently, especially in rapidly changing conditions. Think of it as on-the-fly risk management during uncertain times. Creativity in finding unique solutions to complex issues. What sets blockchain apart from other fields is its novelty and the lack of comprehensive regulations governing it. So, a blockchain enthusiast should be genuinely curious and eager to stay updated with emerging laws and the expanding scope of blockchain applications. Adhering to ethical norms and community guidelines is also crucial. Learning Blockchain Development While some universities offer relevant programs, not many of them are truly extensive. At the same time, some of these courses may be expensive or require a solid previous background. So, you will likely need to rely on self-education at the end of the day. You can build your skills and even craft your first smart contract by exploring various resources, like video tutorials or online forum discussions. Microsoft provides an online course for blockchain basics and development on the Ethereum platform. There are also good free courses available on Coursera, covering topics such as: Blockchain Basics Decentralized Finance (DeFi) Introduction to Blockchain Technologies After these courses, you will have a solid grasp of blockchain's key concepts and models, a deeper understanding of decentralized finance's infrastructure and applications, and the know-how to create smart contracts. What to Check Out Here is a list of possible resources to help you get started and feel confident as you dive into the blockchain world. These references are great for understanding the basics and exploring how blockchain is used in various fields. "The Truth Machine: The Blockchain and the Future of Everything," Michael J. Casey, Paul Vigna. "Blockchain Basics: A Non-Technical Introduction in 25 Steps," Daniel Drescher. "Proof of Stake: The Making of Ethereum and the Philosophy of Blockchains," Vitalik Buterin. "Mastering Blockchain: Inner workings of a blockchain, from cryptography and decentralized identities to DeFi, NFTs, and Web3," Imran Bashir. "ValueWeb: How Fintech Firms are Using Bitcoin Blockchain and Mobile Technologies to Create the Internet of Value," Chris Skinner. Why Is Blockchain Development a Hot Career Right Now? Blockchain's power lies in cutting out the middleman, streamlining management, and shrinking the costs related to record-keeping and transaction verification. Another critical point is the rise of Web3, the next phase of the Internet. It is built on blockchain and revolves around decentralization and a token-based economy. This new web phase embraces novel financial services, NFTs, and digital twins, all skyrocketing in popularity. Moreover, the buzz around companies stepping into the metaverse, where blockchain reigns, is real and growing. A significant thrust is also the integration of blockchain into fundamental technologies across various industries. All this means blockchain developers will be hot property for at least the next three to five years. While initially popular in systems for supply chain, cross-border payments, identity verification, and asset management, blockchain's reach has now extended.

Dev Up 2023: Leveling Up Our Dev Skills, Security Posture, and Careers

One theory about the Gateway Arch is that it is a giant staple connecting the Midwest to the Great Plains. Bridging the Mississippi River, it does really connect East to West in the US. It is also home to a vibrant tech community that is working to connect technology and business goals. This community got together to discuss application development, DevOps best practices, and how to stay safe while delivering awesome features and experiences at the St. Charles Convention Center for Dev Up 2023. Over 75 speakers gave talks on a wide range of subjects across more than ten simultaneous tracks. Topics included development language-focused talks such as "C# Past, Present, and Beyond" from Jim Wooley, DevOps best practices including "ARM, Bicep, knees and toes! Infrastructure as code for beginners" from Samuel Gomez, and even career advice talks like From Curiosity to Career: Becoming an Ethical Hacker from Jason Gillam. While covering every session or lesson learned at Dev Up 2023 would be impossible, here are some highlights from the event. Scenes from dev up 2023 Azure and API Security In his session "Demystifying Web API Security in Azure," Jimmy Bogard started by laying out the short, simple history of how we used to handle authentication when all you needed to worry about was a user connecting to a single web app, namely using cookies. But as we started adding microservices, we suddenly had to start ensuring that apps and services had the right permissions, too. We started implementing Backend-For-Frontends patterns and communicating via APIs. The rise of Zero Trust architecture means we are now in a world of 'verify, then temporarily trust.' While Zero Trust is a great philosophy, it stops short of giving specifications and guidelines, like OAuth lays out. Fortunately for Azure users, there is a clear path leveraging Azure Active Directory. He referred us to the document on the scenario where a daemon application calls web APIs. In this setup, the application requests an access token using its application identity to Azure AD. From there, the application can be issued a role and specific permissions. This allows the developers to define very tightly scoped custom roles and sets of permissions, all without needing to set a password or hardcode any API keys throughout the application. Jimmy has released an example application that shows off this approach. Demystifying Web API Security in Azure from @jbogard "A simpler time..." #DevUp2023 Understanding Data Privacy Is the Local Law Ryan Overton, Developer Advocate at Ketch, took the attendees through the responsibilities and liabilities of organizations who collect and use customer data in his talk "Demystifying data privacy and your responsibilities." He began by explaining that data privacy is not the same thing as data security. Data privacy is what laws and regulations say about how we access and use customer data. Data security is how organizations prevent unauthorized access to that data. Both are important, but getting data privacy wrong could bring hefty fines. He defined specific terms used throughout the legislation and by lawyers when discussing privacy: Data Purpose: The reason the company is requesting the data and what they plan to do with it. Consent: What the user says you can do with their data. Regulation: The specific laws applied to customer data in a jurisdiction. Jurisdiction: The geographic region where a data privacy regulation applies. Legal Basis: The regulatory justification for using data. Basically, how lawyers say, "We are allowed to use X data for Y purpose, according to law Z. Data Subject Rights, DSR: Rights afforded to individuals under the laws. He said the best thing to do when in doubt is to bring in legal counsel early and have them oversee and explain any potential privacy concerns early in the process. This is the easiest and cheapest option when a potential issue is on the table. He said in general, you can almost always assume that the user's current location will inform you of which regulations will apply. For example, someone from France or Germany visiting your site will be covered by GDPR, and you should afford them all those rights. One of the largest issues we face as an industry right now is tracking visitors without relying on cookies. Cookies have been our standardized tool for years. However, in browsers growing in popularity, like Brave, and with recent updates to Safari, cookies are set to off by default. Ultimately, we need to find better ways to honor a user's choices and let users easily opt-in or opt out of sharing their data while still giving them world-class online experiences. Demystifying data privacy and your responsibilities from @ryano9791 #DevUp2023 Thinking In the Number of Nines When you think about downtime, how much is acceptable? This is the core question that Sean Whitesell, Microsoft MVP and Senior Cloud Architect at ArchitectNow, asked in his talk "Saving Your Ass(ets), Azure Resiliency Planning." Beyond just the cost of that service that is down, we need to ask ourselves about the cost of missed deadlines, the loss of focus as the team scrambles to deal with the situation, and how much customer satisfaction and trust you can afford to lose. He defined a disaster as "a condition in which a system or business processes is either performing poorly or not at all available due to an event." This could mean a total outage across the system or a single microservice taking exponentially longer to run than acceptable. We need to build resiliency into our systems, which he and Azure define as "the ability of a system to gracefully handle and recover from failures, both inadvertent and malicious." Sean said that no system can ever guarantee 100% availability. Instead, services list availability in terms of "nines." At 99% uptime, referred to as "two nines," means that it could be unavailable for up to 14.4 minutes per day. "Four nines," or 99.99% uptime, means the system might be unavailable for 8.64 seconds a day. While 8 seconds a day might feel trivial to us at a human level, to a microservice trying to complete an order, this might mean total disaster. The question then becomes, what happens to the in-flight data when that service goes offline, even for a millisecond? What happens when that data is lost in a longer outage? Active/Active vs. Active/Cold The choice in architectural solutions to system availability boils down to active/active and active/cold setups. In an active/active system, you can use a load balancer to distribute requests between two or more live instances of your service spread across multiple availability zones. If one instance or zone goes down, the request is simply rerouted to another live instance, meaning nothing will be lost. This high availability comes with the cost of an exponentially growing hosting bill. In an active/cold scenario, a clone of the active service is loaded into a server but only turned on once triggered. If the active service goes offline, then the cold copy is started. Depending on the configuration specifics, this could take seconds to minutes. This is a far cheaper option, as you will only pay for the running instances, but the chance of data loss goes up dramatically. His real-world examples of where each makes sense are online poker tournaments versus online word search games. In an online poker tournament, having an always available connection is vital to keep the play fair and to manage the in-process games. In a word search scenario, only the final state or periodic status updates would need to be reported back to the game server, as most of the logic is executed on the user's device and is not time-sensitive. Ultimately, the larger the potential lost revenue, the more likely you should look into active/active architectures. Saving Your Ass(ets), Azure Resiliency Planning from @codewithseanw #DevUp2023 Webhook Security Matters Armed with data from over 100 webhook providers, Scott McAllister, Developer Advocate at ngrok, presented "Simple Ways to Make Webhook Security Better." The data he cited is all available on Webhooks.fyi, both a directory of webhook providers and a collection of best practices for providing and consuming webhooks put together by the ngrok team. Webhooks are a programming language agnostic approach for sending messages between distributed systems. They are great because they free developers from caring what language or on what platform a service is written, narrowing the concern to how to parse the JSON, or less frequently XML, reply. They are also easy to test and mock in our work. They also open a whole new set of security concerns, including interception, impersonation, modification, replay, and reply attacks. Scott said using HTTPS when setting up your webhooks is mandatory, encrypting the message while in flight. He also laid out multiple popular strategies for webhook security: HMAC: Hash-Based Message Authentication Code. The provider signs the message using the secret key plus a hashing algorithm and includes the signature in the webhook request as a header. The listener receives the request, repeats the same steps, signs and encodes the webhook message using the secret key, and compares the results, looking for everything to match. This is considered a low-complexity solution that still offers adequate protection for most services. This is used by companies such as GitHub, Shopify, Slack, Twilio, and GitGuardian custom webhook integrations. Asymmetric keys: The webhook provider uses a private key to sign requests, while the listener uses a public key to validate webhook calls. This extends HMAC with a repudiation step that adds a lot of complexity. This method is used by companies like SendGrid, PayPal, and Keygen. mTLS: Mutual TLS. Both the webhook service and the listener go through a TLS handshake, presenting trusted certificates before the message is passed. While very secure, this is a very complex solution; this is the method used by PagerDuty, Docusign, and Adobe Sign. There are other methods as well, but these are the most common. Unfortunately, according to their industry survey, the second most common answer for 'what method do you use for your webhooks' was reportedly 'none.' Hopefully, Scott and his team can inspire more developers to implement better security for their webhooks. "Simple Ways to Make Webhook Security Better" from @stmcallister from @ngrokHQ at #DevUp2023 A Community for All The attendees at Dev Up 2023 got to see a wide variety of talks aimed at all skill and experience levels, from introductory to advanced. While there certainly were many code examples and deeply technical sessions, there were also talks about career advancement and how to be successful working at home. No matter your background, everyone was made to feel welcome. The central goal all speakers had was to help their audience 'level up.' Your author gave three different sessions as well, and helping people level up with code security was central to all. The first covered using git hooks to prevent yourself from committing secrets, as you can do with GitGuardian's ggshield. I also covered what to do if you experience a code leak, which unfortunately happens to almost all of us at some point. The final session, which sparked some really good conversations, was all about the Secrets Management Maturity Model. This model can help you judge where you are on your code security path and plan your route when used as a roadmap. There are a lot of folks out there who want to help you succeed as a developer or security professional. While events like Dev Up are a great way to connect, you don't need to wait for an annual event; there is likely an event in your area sometime soon. If you are looking for an awesome security community to join, we highly recommend checking out the OWASP meetings list or checking out their MeetUp group pages. Let's all get better at coding and code security together.

Embracing 'Hit Refresh': A Blueprint for Engineering Excellence

As an engineer, I have come to realize the immense significance of continuous professional growth in our rapidly evolving field. In order to stay relevant and excel in our careers, we must constantly adapt to the ever-changing landscape of technology. One concept that has greatly influenced my approach to professional development is ‘Hit Refresh.’ This concept, popularized by Microsoft CEO Satya Nadella, emphasizes the importance of embracing change and continuous learning. In the realm of tech literature, “Hit Refresh” stands out as a transformative work. While it’s often regarded as a book for business leaders, its principles hold immense value for engineers. In this article, I will delve into the concept of ‘Hit Refresh’ and explore how engineers can apply it to unlock success and achieve excellence in their careers. Embracing Empathy In the world of engineering, where lines of code and intricate circuits often take center stage, one might wonder about the role of empathy. Yet, “Hit Refresh” reminds us that empathy isn’t just a soft skill; it’s a force that can drive innovation and collaboration. Engineers who understand the people behind the technology — whether it’s users, teammates, or stakeholders — are better equipped to create products that truly meet their needs. Empathy, in essence, becomes the cornerstone of user-centric design and effective teamwork because of various reasons: Understanding User Requirements One of the key aspects of building successful software or technological solutions is understanding the end-user’s requirements. These users can be internal colleagues or external customers. By embracing empathy, engineers can put themselves in the users’ shoes, gaining a deeper understanding of their pain points, preferences, and expectations. This understanding leads to the creation of products that truly resonate with users, resulting in higher adoption rates and customer satisfaction. Effective Collaboration Engineering is often a collaborative effort. Whether you’re working with other engineers, designers, product managers, or stakeholders, the ability to empathize and understand the perspectives of your team members is crucial. It fosters a positive working environment, encourages open communication, and helps in aligning everyone towards a common goal. This, in turn, leads to more efficient and effective project outcomes. Problem-Solving Engineers are problem solvers by nature. Empathy can aid in problem-solving by enabling you to see issues from different angles. When you can understand the challenges faced by different stakeholders, you’re more likely to identify comprehensive solutions. This can be especially valuable when troubleshooting technical issues or optimizing existing systems. Customer-Centric Development In today’s tech-driven world, the focus has shifted from product-centric to customer-centric development. Empathy empowers engineers to prioritize features and improvements that genuinely benefit users rather than just adding more technical complexity. This shift in mindset aligns engineering efforts with the overarching goal of delivering value to customers. Building Inclusive Products Empathy extends beyond understanding the majority of users; it also involves considering the needs of underrepresented groups. Engineers who embrace empathy are more likely to design and develop products that are accessible and inclusive, catering to a diverse range of users. Growth Mindset The concept of a “growth mindset,” popularized by psychologist Carol Dweck, is the belief that abilities and intelligence can be developed through dedication and hard work. In an industry marked by rapid change and constant learning, believing in your capacity to adapt and learn is invaluable. Engineers with a growth mindset can have a profound impact: Embracing Challenges Engineers often encounter complex and novel problems that require creative solutions. A growth mindset encourages engineers to embrace these challenges rather than shy away from them. Instead of feeling discouraged by difficulties, those with a growth mindset view them as opportunities to learn and improve. This attitude fosters resilience and the ability to tackle increasingly complex technical problems. In my own experience, I once found myself mired in a challenging situation while setting up a Continuous Integration and Continuous Deployment (CICD) pipeline on GitHub Actions. For several days, I grappled with a seemingly insurmountable problem that had me scratching my head. It would have been easy to give in to frustration, but I chose a different path. Instead, I embraced a growth mindset. I kept experimenting with various configurations, delved into extensive online research, and actively engaged with the community on platforms like StackOverflow. Those days of perseverance paid off in the end, and I can vividly recall the triumphant feeling when I finally cracked the code. Continuous Learning The tech industry is ever-evolving, with new programming languages, tools, and frameworks constantly emerging. Engineers with a growth mindset are more inclined to view learning as a lifelong journey. They proactively seek out opportunities to acquire new skills, whether it’s through formal education, online courses, or on-the-job experiences. This dedication to learning ensures that engineers stay up-to-date with the latest trends and technologies. Adaptation to Change Technology landscapes can change rapidly, and market demands can shift overnight. Engineers with a growth mindset are better equipped to adapt to these changes. They don’t become complacent with existing solutions but are eager to explore new approaches and stay agile in the face of evolving requirements. Overcoming Failure Failures and setbacks are inevitable in any engineering project. However, individuals with a growth mindset view failure as a stepping stone to success. Instead of dwelling on mistakes, they analyze what went wrong, learn from it, and apply those lessons to future endeavors. This resilience in the face of failure can lead to more innovative and robust solutions. Fostering Innovation Innovation often arises from pushing the boundaries of what is currently known and possible. Engineers with a growth mindset are more inclined to explore unconventional ideas and experiment with new technologies. This willingness to take risks and explore the unknown can lead to groundbreaking innovations. Mentorship and Collaboration Engineers who embrace a growth mindset not only seek personal growth but also support the growth of their colleagues. They are more likely to mentor and collaborate with others, sharing knowledge and experiences to help everyone on the team develop and excel. In addition to my technical work, I’ve also had the privilege of giving back to the engineering community through mentorship. I mentor engineers on platforms like ADPList, and it’s an incredibly fulfilling experience. Guiding fellow engineers, sharing knowledge, and helping them navigate their own career paths is not only rewarding but also a way to foster collaboration within our industry. Continuous Learning The tech world never stops evolving, and engineers who commit to lifelong learning are the ones who thrive. “Hit Refresh” emphasizes the importance of staying relevant through continuous education and adaptation. As an engineer, it’s essential to keep learning, whether it’s about emerging technologies, programming languages, or innovative methodologies. Continuous learning ensures that your skills stay sharp and that you remain at the forefront of your field. Staying Relevant Technology is constantly evolving. What was cutting-edge a few years ago may become obsolete today. Engineers who embrace continuous learning ensure that their skills and knowledge remain up-to-date. This is particularly important in fields like software development, where programming languages, frameworks, and tools can change rapidly. Adapting to Emerging Technologies New technologies and paradigms are constantly emerging in engineering and technology. For example, the rise of artificial intelligence, blockchain, and edge computing has introduced entirely new domains. Engineers who commit to continuous learning can transition into these emerging fields and contribute meaningfully to projects involving them. Problem Solving and Innovation Learning is not just about acquiring theoretical knowledge but also about honing problem-solving skills. Engineers often encounter unique and complex challenges. Continuous learning equips them with the ability to analyze problems critically and devise innovative solutions. Career Advancement Engineers who invest in their learning and professional development tend to advance more rapidly in their careers. Acquiring new skills and certifications can open up opportunities for leadership roles, specialized positions, or higher-paying jobs. Building a Growth-Oriented Culture Engineers who prioritize continuous learning set an example for their colleagues and contribute to building a culture of growth and development within their organization. This can inspire others to invest in their learning journeys. Networking and Collaboration Learning often involves interaction with peers and mentors. Engaging in courses, workshops, and conferences provides opportunities to network with professionals in your field, exchange ideas, and collaborate on projects. This can lead to valuable connections and partnerships that enhance your career. Resilience in Uncertain Times The ability to learn and adapt is a valuable asset in times of uncertainty, such as economic downturns or global crises. Engineers who continuously upgrade their skills are better positioned to navigate career transitions or explore alternative opportunities when needed. This seems more important than ever in these times! Ethical Tech Development Technology, at its core, is a tool that can shape societies and impact individuals. Ethical tech development, a central theme in “Hit Refresh,” reminds engineers of their ethical responsibility in creating technology. It’s about more than just what can be done; it’s about what should be done. Engineers should prioritize user privacy, inclusivity, fairness, and environmental sustainability. By adhering to ethical principles, engineers can contribute to technology that not only advances but also benefits society. Responsible Innovation Engineers are at the forefront of technological advancements, and they play a pivotal role in shaping how technology is developed and deployed. Embracing ethical considerations means engineers are not just focused on what can be done but on what should be done. This approach fosters responsible and ethical innovation. User Privacy and Data Security Ethical tech development places a strong emphasis on safeguarding user privacy and data security. Engineers must design systems and applications with privacy in mind, ensuring that user data is protected from breaches and unauthorized access. Inclusivity and Accessibility Ethical tech development also involves creating products and solutions that are inclusive and accessible to all. Engineers should consider the diverse needs of users, including those with disabilities, and strive to make technology universally usable. Bias and Fairness Developing technology ethically requires addressing bias in algorithms and AI systems. Engineers need to be aware of the potential for bias in data and algorithms and take steps to mitigate it to ensure fair and equitable outcomes. One of the most notable real-life examples of bias in technology involves a study conducted by the Gender Shades project led by Joy Buolamwini, a researcher at the MIT Media Lab. The Gender Shades project examined commercial facial recognition systems from prominent tech companies to assess their accuracy in gender classification across different racial and gender groups. The findings were eye-opening. The study revealed significant disparities in accuracy based on both gender and race. Specifically, the facial recognition systems performed with high accuracy for lighter-skinned and male faces but exhibited lower accuracy when analyzing darker-skinned and female faces. In some cases, the error rates were significantly higher for women of color compared to lighter-skinned men. This real-life example highlights the pressing need for engineers to prioritize fairness and address bias in technology to ensure equitable outcomes for all individuals, regardless of their gender or racial background. Environmental Sustainability The ethical responsibility extends to environmental considerations. Engineers should work towards creating technology that minimizes its carbon footprint and contributes to sustainability goals, whether through energy-efficient designs or eco-friendly practices. Transparency and Accountability Ethical tech development demands transparency in how technology works and how it impacts users and society. Engineers can contribute by designing systems that are explainable and by participating in ethical discussions within their organizations. Navigating Change and Uncertainty The tech industry is a turbulent sea of change and uncertainty. “Hit Refresh” teaches us that adaptability, resilience, and strategic thinking are essential traits for navigating these waters. Engineers should be ready to embrace change, learn from setbacks, and make data-driven decisions. By staying true to their core values, fostering collaboration, and managing risks effectively, engineers can thrive in an environment characterized by constant change. Adaptability In the tech industry, change is constant. New technologies emerge, market demands shift, and unforeseen challenges arise. Engineers who can adapt to these changes are better equipped to thrive. Nadella’s journey reminds engineers that adaptability is not just a desirable trait but a necessity. Resilience Uncertainty often brings adversity. Engineers may face project setbacks, technical challenges, or economic downturns. Nadella’s experiences underscore the importance of resilience — the ability to bounce back from setbacks, learn from failures, and keep moving forward. Strategic Thinking Navigating change and uncertainty requires strategic thinking. Engineers can learn from Nadella’s approach to repositioning Microsoft by focusing on cloud computing and AI. Strategic thinking involves analyzing the landscape, identifying opportunities, and making informed decisions. Staying True to Core Values Even in times of change, Nadella emphasizes the importance of staying true to Microsoft’s core mission. Engineers should also consider their organization’s values and mission as guiding principles during turbulent times. These values can provide stability and purpose. Collaborative Leadership Nadella’s leadership style encourages collaboration and teamwork. Engineers can apply this principle by fostering a culture of collaboration within their teams. Collaboration often leads to more innovative solutions and better problem-solving. Data-Driven Decision-Making Nadella’s data-driven approach to decision-making is relevant for engineers who work with data-driven technologies. Making decisions based on data and insights rather than assumptions can lead to more informed and effective solutions. Continuous Improvement Change and uncertainty provide opportunities for continuous improvement. Engineers should seek feedback, evaluate their processes, and identify areas for enhancement. Nadella’s journey is a testament to the power of continuous improvement. Implementing ‘Hit Refresh’ in Your Daily Routine Embracing ‘Hit Refresh’ requires a deliberate effort to incorporate continuous learning and change into your daily routine. Here are some practical strategies for implementing ‘Hit Refresh’ in your engineering career: Set aside dedicated time for learning: Schedule regular time slots in your calendar specifically for learning new skills or technologies. Treat this time as non-negotiable and commit to it just as you would commit to other work-related tasks. Explore new technologies and tools: Stay curious and explore emerging technologies and tools that can enhance your skill set. Experiment with new programming languages, frameworks, or development methodologies to broaden your knowledge and stay abreast of industry trends. Engage in collaborative projects: Seek opportunities to work on projects that challenge you and expose you to new experiences. Collaborating with colleagues from different backgrounds and skill sets can provide fresh perspectives and foster innovation. Join online communities and forums: Engage with like-minded professionals in online communities and forums to exchange ideas, seek advice, and stay updated on industry trends. Active participation in these communities can help expand your network and open doors to new opportunities. Reflect on your achievements and learning: Regularly reflect on your accomplishments and learning experiences. Take note of the skills you have acquired, the challenges you have overcome, and the lessons you have learned along the way. This reflection will not only boost your confidence but also provide a roadmap for your future growth. Tools and Resources for Embracing ‘Hit Refresh’ in Software Engineering Fortunately, there are numerous tools and resources available to support engineers in their journey of embracing ‘Hit Refresh.’ Here are a few that I highly recommend: Online learning platforms: Platforms such as Udemy, Coursera, and Pluralsight offer a wide range of online courses on various topics in software engineering. These courses provide flexible learning options and enable engineers to acquire new skills at their own pace. Technical blogs and podcasts: Subscribe to technical blogs and listen to podcasts that cover the latest trends and advancements in software engineering.

How Can Low-Code Tools Reduce Cost During Recession

The software industry is currently in the clutches of a global recession. However, the ongoing global economic downturn has shifted energy to establish new business models and software development processes, aiming at order-of-magnitude reductions in terms of IT and development costs. But it doesn’t strictly mean cutting back on budgets only. In these challenging times, often, CEOs and CTOs define their software development spending as a “black box,” but the returns are not always achieved in the expected or most beneficial way. Why? Because of implications like: Incomplete risk evaluation and mitigation Lack of flexibility imposed on different levels (DevOps, remote work environment, etc.) Low degree of automation Overlapping deadlines and an increasing number of projects Slow time to market Inefficient staffing models Inability to keep up with increasing user demands Incapability to handle the developer shortage crisis Sprinting back and forth between projects Among all these factors, plus the high percentage of late delivery on projects, how does an organization reduce software development costs during a recession? As Akis Sklavounakis, Senior Director Analyst at Gartner, highlights, “Investment in new application development is 17% of the total IT spend, making it a fruitful place to look for opportunities to cut costs, optimize spend, or improve value.” In other words, consolidate tooling from dozens or even hundreds of tools in some large enterprises to deliver significant cost savings. Are automation and related technologies like the low-code App Builder(tm) the panacea, then? Seems like it. Everyone Is Anxious About Inflation The battle against inflation is a key concern for central banks, even with some predictions that global inflation rates will decrease in 2023. Yet, despite the slower growth pace, the IT market remains a bit more stable compared to other sectors. Software services and product development expenditures climbed by 9.6% and 6.2%, respectively. However, the expense of hardware is estimated to have decreased by 5%. All this drives investments in automation and low-code technology that can empower organizations to: Optimize their expenditures on products, people, processes, programs Streamline software development life cycle More easily adapt to the changing economic environment Score better ROI Let’s visualize this with some examples. Example 1: Cost of a Single Team Member For a programmer to "code" applications or a component, it costs X amount of money per month and year. So, let’s do some calculations for the time to implement an app. Assuming an average salary of $120,000 per year (10K a month), developers cost between $50 and $60 per hour. Suppose a developer spends 3 hours a day, three days a week, for four weeks, on actually creating an app for different frameworks with specific layouts, controls, and theming capabilities. In that case, this work amounts to $540 per week, which means $540 x 4 weeks = $2160. This is the monthly cost for a developer. And you need many developers (and designers, testers, and documentation specialists) to build software. However, purchasing a low-code tool with UI components significantly reduces the amount. For example, tool X costs $1295 per year. Which is a little more than $100 per month compared to the monthly salary of one developer. Can you replace a team member for $100? No, absolutely not. What you gain is exponential delivery efficiency, resulting in overall cost reduction and higher, consistent delivery. Things that are handled with low-code platforms: POCs Kickstarting implementation on a web framework like Angular/Blazor Implementation of functionalities like a web page with bindable lists/grids with data, site navigation with routing, login screen GitHub repository setup and CI setup Angular/Blazor application setup - installing dependencies and project configurations The biggest value that app-building platforms bring relates to both productivity and efficiency, plus the easiest way to switch from one framework to another (i.e., you can easily go from Angular to Blazor or Web Component app in a single click). The example above doesn't measure the value of produced code per day but the value of efficiency in a development process. This results in more quality code on top of what is provided and a significant cost reduction in terms of altering the code. Key things to consider: What would it cost me to build the same number of apps with and without the low-code platform? How long did it take to create most of the applications? What kind of energy is spent on maintaining and updating old applications? What would be the result if developers had more time to focus on mission-critical projects? Example 2: Considering a Whole Team (PM + UX Design + Development) * x Avg Cost/Hour Staff = Approximate Cost Assuming an average salary for a PM+UX Designer + developer of $350,000 per year (30K a month). In this case, the cost is roughly $180 per hour. Again, we consider an average of three hours * three times a week. We've calculated a hypothetical cost of implementation to 3 days * 3 hours * $180 = $1620 per week. For a month, this means $1620 x 4 weeks = $6480. Compared to purchasing product X at a price of $1295 per year ($100 / month), your cost is $1.75 / day to add exponential efficiency to your team’s output. Some of the consuming processes that are handled with the help of low-code platforms: Visual Design implementation Communication between the team — Sync on design, implement it, request new styles, change design, implement it again POCs Application flow creation Kickstarting implementation on a web framework like Angular, Blazor, or others. Implementation of functionalities like a web page with bindable lists/grids with data, site navigation with routing, login screen GitHub repository setup and CI setup Angular/Blazor application setup. Installing dependencies and project configurations Key things to consider: Time spent on UX is time not spent on development. Time spent figuring out how to make a column resizable in-app is time not spent on QA. Time testing the same resizable column is time not spent on developing formulas. You are saving expenses in every aspect of building and delivering software with low-code tooling. How Can Low-Code Tools Reduce Cost During Recession? When it comes to low-code tools and their role in software development cost reduction, it’s important to point out that the primary goal is to achieve cost optimization - not simply to implement budget cuts. What is the difference? Budget cuts aim at reducing spending. The downside here is it may have an inefficient and disproportionate impact on everything in the full product development life cycle – DesignOps, DevOps, people, and other tools. Cost optimization helps companies achieve less expense + greater business value + optimized processes. It is more strategic. And it has better long-term perspectives. Here's how it happens through the adoption of low-code tools. Leveraging a Proven Single Solution Across Multiple Departments and Fusion Teams Having fewer tools in place means less maintenance and easier support from your IT team, quicker on-training of employees, digitalization, one subscription plan only, and no need to use different plans for different tools. When all costs for application design and development are consolidated into a single platform, it results in fewer additional expenses. Automation of Mundane and Repetitive Tasks Through Component Reusability One other thing that low-code platforms are so great at is replacing manual tasks with automated processes. More comprehensive examples include a full-featured toolbox, so you don’t need to invest money, time, and effort in creating an in-house UI library. Instead, you can use out-of-the-box, reusable, and customizable components with feature parity across technologies (Angular, Web Components, Blazor Server, Blazor WebAssembly), achieving about 80% faster development and time to market. Code Preview and Production-Ready Code Generation Low-code tools reduce costly error-prone hand-coding in areas like screen design, UX flows, theming, branding, data binding, deployment, and even GitHub integration. Some app builders offer quicker transitioning from design to code, converting files in Sketch or Figma to pixel-perfect code with the help of an integrated design system. And what’s more, there is no need for manual HTML and CSS tweaking, which, according to Gartner, can take up to 60% of the application development time. Time-consuming POCs and Designer-Developer Handoffs Are Eliminated Using low code tooling, you gain additional savings from the high cost of potential UI redesign and bug-fixing that always occurs post-deployment. Because you are prototyping and testing in the low-code tool, you can ensure customer acceptance before deployment, thus reducing code churn and the 10X cost of post-deployment bug fixes. Promoting a More Flexible Enterprise Culture and Remote Work Environment + Invite Citizen Developers Adapting a talent-anywhere approach is a great way to simultaneously keep up with it and save on IT costs, tackle the developer shortage, and democratize code. This lets companies take advantage of the growing pool of citizen developers, leaving experienced programmers to churn out complex application algorithms. In addition, they can also respond to a continuous disruptive demand-supply trend where the demand for more and more innovative solutions exceeds the availability of dev experts who can create them. Switching to this also eliminates spending in areas that no longer fit the post-pandemic world. In this regard, a Gartner survey of 127 company leaders of HR, Legal and Compliance, Finance, and Real Estate reports that 82% of respondents intend to allow remote work some of the time. Whereas 47% intend to permit employees to work remotely full-time. In the most practical sense, this will reduce the cost of renting or buying huge office spaces. In a more abstract sense, this will foster a different workplace culture that prioritizes collaboration and transparency. Lower Total Cost of Ownership (TCO) The total cost of ownership refers to the purchase price (i.e., short-term price) of a tool plus the costs of operation (long-term price) for the entire life span and the time the tool is in use. Typically, an IT company invests in design tools, software development platforms, UI toolboxes, analytics tools, team management systems, etc. Low-code tools eliminate the need for that many tools while reducing costs on installation, transition costs, employee training, security testing, future upgrades, and more. How come? Because they work as a single source of truth and are able to build apps with a single code base that are more scalable, maintainable, testable, and easily deployable than any individual or team can guarantee. Amid the economic crisis, IT companies are searching for every opportunity to rationalize product development costs and operations. That’s where low-code development fits in. There is a great 3-phased approach suggested by McKinsey to achieve transformation and minimize disruption to the business that is very applicable to the current economic state and the way low-code platforms weigh in as game changers. Undoubtedly, low-code tools are here to stay. In challenging times when cost reduction and optimization are a must, these technologies can achieve cost efficiency, streamline the software development life-cycle, deliver proven ROI, and help companies adapt to the dynamic economic environment.

Experience vs. Certifications in DevOps: Bridging Theory and Practice

"When hiring for DevOps engineering roles, what matters more—certifications or experience?" This question reverberates through the corridors of countless tech companies as the significance of DevOps engineering roles only grows in the evolving digital landscape. Both elements — certifications and experience — offer valuable contributions to an engineer's career. Certifications such as AWS, CKA, GCP, Azure, Docker, and Jenkins represent the structured, theoretical understanding of the technology landscape. On the other hand, experience serves as the real-world proving ground for that theoretical knowledge. But which of these two carries more weight? Here's an analysis infused with curiosity and passion, grounded in the technical and business realities of our day. The Case for Certifications Certifications provide a clear, standardized benchmark of an engineer's skill set. They attest to the individual's current knowledge of various tools, systems, and methodologies, ensuring their technical prowess aligns with industry standards. For businesses, hiring certified professionals can bring assurance of the engineer's ability to handle specific systems or technologies. This is particularly crucial in the early stages of one's career, where the lack of hands-on experience can be supplemented by formal, industry-recognized credentials. Certifications also speak to an engineer’s dedication to continuous learning — an invaluable attribute in a sector driven by relentless innovation. Furthermore, they can offer competitive advantages when dealing with clients, projecting the organization's commitment to expertise and quality. The Strength of Experience However, while certifications ensure theoretical knowledge, the chaotic, unpredictable terrain of DevOps often demands a kind of learning that only experience can provide. Real-world situations seldom stick to the script. Experience helps engineers tackle these unpredictable scenarios, providing them with a nuanced understanding that's hard to derive from certifications alone. Experience translates into tangible skills: problem-solving, strategizing, decision-making, and team collaboration — all of which are critical to managing DevOps. An experienced engineer can leverage past learnings, understanding when to apply standard procedures and when to think outside the box. The maturing engineer who has faced the heat of critical system failures or the pressure of ensuring uptime during peak loads often develops a tenacity that cannot be simulated in a testing environment. Such experiential learning is priceless and can make a marked difference in high-stakes situations. Perception and Certifications: The "Customer's" View While businesses are right to weigh the benefits of certification against experience, they must also factor in another crucial element — the perspective of "customers," who can be either paying customers in a B2B relationship or internal stakeholders from other teams or departments. Often, these "customers" feel more confident knowing that certified professionals are managing their critical infrastructure. Certifications serve as a validation of a service provider's technical skills, reassuring "customers" of the team's capability to manage complex tasks efficiently. From the "customers'" viewpoint, seeing a certified engineer indicates that the individual, and by extension, the company, has met stringent, industry-approved standards of knowledge and skills. While experience is highly valued, it is sometimes seen as more subjective and challenging to quantify, leading to "customers" placing substantial emphasis on certifications. Certification Renewals and Organizational Goals Certifications, particularly those that require renewals, ensure that engineers stay current with the evolving technology landscape. However, it's important to assess whether pursuing certification renewals aligns with the organizational goals. If a particular certification does not contribute directly to the objectives of a project or the broader organizational strategy, its renewal might not be necessary. The resources spent on such renewals might be better directed toward areas that contribute directly to the organization's mission. The Organizational Benefits of Certification Furthermore, when an organization itself earns certification, such as becoming an AWS Partner or a Kubernetes Certified Service Provider (KCSP), it opens a new realm of possibilities. These certifications not only validate the company's expertise and capabilities but also enhance its market credibility and competitive edge. As an AWS Partner, for example, companies can access a range of resources such as training, marketing support, and sales-enablement tools. They can also avail of AWS-sponsored promotional credits, allowing them to test and build solutions on AWS. Being a KCSP, on the other hand, demonstrates a firm's commitment to delivering high-quality Kubernetes services. This certification also assures "customers" that they are partnering with a knowledgeable and experienced service provider. Such partnerships and certifications can help organizations win more significant contracts, attract more clients, and also retain talented engineers seeking to work with recognized industry leaders. They demonstrate the organization's commitment to industry best practices, continual learning, and staying at the forefront of technological advancements. Bridging the Gap Certifications Experience Provide a structured, theoretical understanding of technology Provide practical, hands-on knowledge Prove an individual's skills against industry standards Offer real-world problem-solving abilities Indicate dedication to continuous learning Display adaptability and tenacity in face of real-world challenges Provide an edge in competitive scenarios Offer insights into effective team collaboration and decision-making It's crucial to remember that neither certifications nor experience can stand alone as the defining factor in DevOps engineering roles. The stage of an engineer's career and the maturity they bring to the role are products of a judicious blend of both. For those at the early stages, certifications can help them stand out and demonstrate a foundational knowledge of DevOps principles. As their career progresses, their accumulated experience, coupled with advanced certifications, exhibits a growth mindset, adaptability, and an in-depth understanding of DevOps systems and practices. Final Thoughts As we draw this discussion to a close, let's return to our initial question: "When hiring for DevOps engineering roles, what matters more — certifications or experience?" Well, we've navigated through the different stages of a DevOps engineer's career, weighed the importance of certification against the gold of experience, and taken into account the perspectives of various "customers." The conclusion is clear: it's not a case of either-or. The debate should not be about choosing one over the other, but understanding how they can symbiotically contribute to an engineer's career. Can we truly measure the importance of the structured learning that certifications offer? Can we quantify the practical wisdom that comes with experience? These are questions we may ponder, but what remains unquestionable is the unique value they both bring to the table. When we consider the perspective of the "customers", who wouldn't want the assurance that their DevOps team is armed with both certified skills and hands-on experience? And for organizations seeking to boost their reputations, why not aspire to hold industry-recognized certifications and partnerships? After all, they enhance market credibility and pave the way for bigger opportunities and promising collaborations. In conclusion, experience is an invaluable asset, a truth universally acknowledged, but the value of certifications — for individuals and businesses alike — should never be understated. Certifications and experience form a powerful combination that assures "customers," motivates teams, and drives business growth in the world of DevOps. The question then is not whether we choose between them, but how we harmoniously integrate both in our practices and operations. No matter where you stand on the spectrum of experience versus certification, remember this: they are not mutually exclusive. Both can coexist, intertwining to form a stronger, more versatile DevOps engineer. For professionals seeking to stay relevant and competitive in the fast-paced world of DevOps, the path forward is clear — embrace both theory and practice. Pursue certifications to keep up with the evolving landscape, and continually hone your skills through hands-on experience. This is the recipe for success in the thriving and dynamic field of DevOps. In the realm of DevOps, the balance between experience and certification is a delicate one, and the pendulum should never swing too far in either direction. Instead, let's allow them to work in concert, building a stronger, more comprehensive understanding of DevOps and its practices. After all, isn't that the essence of DevOps itself — bridging the gap, fostering collaboration, and creating more holistic, efficient, and powerful systems? "Knowledge comes, but wisdom lingers." — Alfred Lord Tennyson
