Six months have passed since the extensive rollout of GitHub Copilot to Volvo Cars' developer community. "We expected significant efficiency gains of approximately 20%, but tasks like unit testing have surpassed expectations and seen gains of up to 40%", says product developer Sabina Edenlund, who sits on Volvo Cars' Gen AI committee. GitHub Copilot assists developers with testing, explaining, and generating code, and can support the advanced ‘autocompletion’ of coding. ➡ Learn more how Volvo Cars benefited from GitHub Copilot https://lnkd.in/ee9f6Y7s #microsoftazure #GitHubCopilot #microsoftadvocate

I'll be talking about building future-proof React applications on the 30th of May in Bucharest. Everyone needs to have a set of principles they follow so they don't have to think about every problem from scratch. I'll tell you how I've been building React applications for the last 8 years. What works. What doesn't. What to focus on to make sure you don't have to rewrite your application every year. Because programming is about solving problems. But engineering is about maintaining those solutions over time.

I recently read an informative post by Tomas Votruba that changed my perspective on something. Instead of focusing just on employing highly experienced "senior" developers, he makes a persuasive case for emphasizing a well-managed, mature codebase. His core idea is that a clean, systematized codebase can actually boost productivity and reduce the need for those highly advanced coding skills. With solid architecture and consistent practices in place, even less experienced devs can work effectively. "Take care of your codebase, and your codebase will take care of you when you're older." I'd encourage checking out Tomas's full post if you're interested in that side of things. Let me know what you think! https://lnkd.in/ecb4sTnx #codebase #developer #seniordeveloper #coding #programming #ITindustry #hiring #tech

It is said that sometimes writing automated tests is an afterthought. Perhaps, it is even more so for User Interface (UI) related works, because if we can test it in our browser where it is more "perceivable", why test it in "headless" mode? It is hard, boring, etc. etc. When writing automated tests is treated like a chore, it makes sense that the activity itself is not enjoyable. That was why I wrote this blog post: if we don't see past the effort, it is hard to see the value. Hopefully, this blog post can spark something in our mind which allows us to have more fun in writing automated tests.

It's quite eye-opening to learn that a lot of software development projects hit a snag right at the finish line. Did you know that a whopping 80% of the work actually happens in the last 20% of the project? This crucial stage often doesn't get the attention it deserves. Many development agencies find themselves struggling here because of poor planning and budget issues, which sadly leads to projects being abandoned prematurely. What starts as a 6-9 month journey can unexpectedly stretch into years or, even worse, never get completed.

How graalvm helps to reduce startup time. It pays price for compile time. An overview article. Unlike JIT mode, where compilation and execution happen at the same time, in AOT mode the compiler performs all compilations during build time, before the execution. The main idea here is to move all the "heavy lifting" — expensive computations — to build time 1. Points-to analysis 2. Initialisations at build time 3. Heap snapshotting But if this is so good, why has it not replaced jvm already ? 1. Probably people are used to jvm infrastructure and its tools 2. Increased build time where quick start isn't critical for applications 3. platform dependent executable native code output instead of byte code https://lnkd.in/g8NXjs2B #graalvm #java

AI will never replace humans unless the work is almost menial and requires little human intelligence. If Ai's can only do simple work, is it really worth it to replace menial work (paid cheaply) with error prone AI systems? Domain expertise requires humans to know it and engage intelligently through experience with it. Novices don't just use AI to become domain experts like in the Matrix. We don't just download AI knowledge into our brains. The reality is that novices don't know where or how to start, and AI doesn't change that. For actual work expertise, AI has done nothing to replace domain experts. AI is a tool for domain experts to use as a supplemental, not to replace them. And if AI tries to replaces the junior/assistant level folks then it shots itself in its metaphoric foot as there will be fewer senior domain experts to use AI in the future. AI threatening to replace humans only ensures that AI defeats itself. AI cannot replace humans. AI are tools for humans. Nothing more. excecs with fantasies of downsizing their teams by 90% and replacing them with AI are the yetters. They look at AI and say its not there just Yet, but it ill get there. It will do anything that we want it to so we can justify all the layoffs that we need to. Meanwhile, they likely started with the amount of people they wanted to layoff. AI didn't lay off anyone. Greedy execs did.

I've heard arguments against unit testing. Sometimes they say that they should only cover code where there is business logic. 1. Unit tests have a limited purpose. 2. Unit tests lead to more complicated design. 3. Unit tests are expensive. 4. Unit tests rely on implementation details. 5. Unit tests don't exercise user behavior. Are these arguments you've heard? Have you heard other arguments? Clearly, I disagree with all of this. Unit tests are a powerful tool when designing large enterprise-level systems with layers of complexity. I've seen massive code-bases where Unit Testing is all that ensured a solid and stable environment.

Job listings should stop using non-sense requirements like: ❌ 5 years in C# ❌ 7 years in React ❌ 10 years in enterprise software development They are not only poor metrics but also scare away developers. Judging a developer by the number of years is like judging a book by the number of pages. I know many young developers who are already better than many seniors with 10 years of experience but repeated the same year 10 times. Value developers for the depth of their journey, not the length of it.

System Design for front-end engineers. Usually, data patterns are taught from the perspective of backend engineers. Our assumptions seep into our solutions. Global caches, central logging, persistent database, and so on. But what if users have multiple devices? How do we ensure users don't download movies? These solutions deserve a series of their own. And that's what Akshay and Chirag have done. Their course on front-end engineering is unique. It explains popular system design concepts, with practical examples. Check out the sample networking, communication, and security videos for more details.

Software development is an endurance sport. Real value creation comes from small iterations delivered consistently over time. So how do you build successfully and sustainably long term? By finding your zone. Whether it's pushing out code, reviewing pull requests, or collaborating with teammates, every little bit adds up. Some best practices include: 🎯Commits that are small, frequent, and consistent. 🎯Coding days that are consistently above average. 🎯PRs that are sized for their stage of development (large PRs earlier in development and smaller PRs closer to the end of a sprint) 🎯High review participation 💡 Learn more about building successfully and other patterns for data driven engineering leadership by checking out our guide below:  https://lnkd.in/efAZ9SXw #SoftwareEngineering #EngineeringLeadership #EngineeringManagement #DevOps
