Open Source Microsoft Bought GitHub for $7.5 Billion and Has Been Slowly Wrecking It Ever Since Linus built Git in 10 days. GitHub became where open source lives. Then Microsoft paid $7.5B, killed Atom, trained Copilot on your code, corrupted main branches with a merge queue bug, and folded the whole thing into CoreAI. Here's the full story.
Artificial intelligence Build Your Own AI Coding Assistant With Access to Your Entire Codebase (2026) GitHub Copilot charges $19/month and sends your entire codebase to Microsoft's servers. You can build something better — one that knows your whole project, costs $0/month after hardware, and never phones home.
Programming Python's frozendict Is Finally Happening — And It's More Important Than You Think Python 3.15 ships a built-in frozendict — hashable, O(1) lookups, order-preserving, thread-safe by design. Here's the full technical picture: the 14-year history, how hashing works, what it unlocks for lru_cache and free-threaded Python, and every sharp edge you need to know before you use it.
Programming Featured r/programming Just Banned LLM Discussions. I Understand Why. I Still Disagree with it. The largest programming community on Reddit banned all LLM content for April. The frustration behind the decision is real. The decision itself is a mistake. Here's the full picture: what the ban covers, why it happened, what the data says, and where I actually land on AI as a coding tool.
Programming PEP 816: Python Finally Gets Serious About WebAssembly CPython has had informal WebAssembly support since Python 3.11. PEP 816 changes that. Brett Cannon just locked down exactly which WASI and SDK versions each Python release will target — and why SDK versions 26 and 27 got blacklisted entirely.
Web Development TypeScript 6.0 Is Out, and It's the End of an Era TypeScript 6.0 dropped today. It's the last version of TypeScript written in TypeScript. Strict mode is on by default, ES5 is gone, outFile is dead, and TypeScript 7.0 — rewritten in Go — is right behind it. Here's everything that changed and what you actually need to do.
Artificial intelligence Amazon's Mass Layoffs, Kiro AI, and Why Shipping AI-Generated Code to Production Should Terrify You Amazon fired 1,800+ engineers while forcing staff onto its Kiro AI tool. Here's why that's a cybersecurity disaster waiting to happen — and what it means for every developer.
Programming Featured Build Your Own Stack-Based Bytecode Virtual Machine in C Ever wonder how Python's CPython, the JVM, or the Lua VM actually execute code under the hood? In this article, we build a stack-based bytecode virtual machine from scratch in C.
Programming C# 14 Is Actually Good And I'm Not Happy About It C# 14's most significant new features explained — what changed, why it matters, and why the language that used to mean enterprise bloat is now genuinely good.
Programming Java 26 Is Here, And It's Finally Finishing What It Started JDK 26's ten targeted features explained — what's shipping, what it means for production Java, and why the language keeps reshaping the terrain while you're not watching.
Cybersecurity What is Cybersecurity? The Field That Keeps the Internet From Collapsing Cybersecurity is the discipline of protecting systems, networks, and data from attack, damage, and unauthorized access. Here's what it actually covers, how attacks work, how defense works, and why every developer needs to understand it.
Programming What is Go? Google's Language That Won the Cloud Go is Google's compiled language built for simplicity and brutal concurrency. Here's what it is, how it works, and why it runs half the cloud infrastructure you use every day.
Software Development What is Go? The Language Google Built for Production Engineering Go is a statically typed, compiled language built at Google in 2009. It compiles to a single binary with no runtime dependency, starts in milliseconds, and handles concurrency through goroutines and channels. Docker, Kubernetes, and Terraform are all written in Go. Here is why.
Programming What is Rust? The Language That Makes Systems Programming Safe Rust eliminates entire categories of bugs — null pointer dereferences, buffer overflows, data races, use-after-free — at compile time with no runtime overhead. Microsoft, Google, Amazon, and the Linux kernel all use it for systems code.
Programming What is Java? The Language That Runs Minecraft, Your Bank, and Half the Internet Java has been declared dead approximately forty times since 1995. It still runs Minecraft, Android, LinkedIn, Twitter's backend, and the financial systems that process your paycheck. Here is what the language actually is, how the JVM works, and why it refuses to die.
Programming What is Python? Enterprise, Data Science, and the Backend of the Web Python runs Instagram, Dropbox, Netflix, Spotify, and Reddit. It trains the models that power modern AI. It processes petabytes of data in enterprise pipelines. And I ignored it for years because I thought it was just for academics. Here is what changed my mind.
Web Development Node.js vs Deno vs Bun: Picking the Right JavaScript Runtime in 2026 Three JavaScript runtimes. Three different philosophies on what the developer experience should feel like. Here's how they compare on performance, ecosystem, tooling, and the only decision that actually matters for production.
Web Development What is Node.JS? Using JavaScript without the Browser Node.js took the V8 engine out of Chrome and ran it on a server. That sounds like a small change. What it actually did was flip how developers think about I/O — and spawn an ecosystem of two million packages.
Web Development JavaScript vs TypeScript: Which One Should You Actually Use? TypeScript is JavaScript with types. That's the short answer. The real answer involves a friend who was right about something I didn't want to hear, a production bug that types would have caught immediately, and the slow realization that the compiler was never the enemy.
Web Development What is TypeScript? Why I Finally Stopped Fighting the Type System TypeScript is JavaScript with types. That's the short answer. The real answer involves a friend who was right about something I didn't want to hear, a production bug that types would have caught immediately, and the slow realization that the compiler was never the enemy.
Programming Parallelizing Java Streams with Virtual Threads: Building vtstream You know what's funny about parallelStream() in Java? Everyone acts like it's this magic performance switch. Just slap .parallel() on your stream and suddenly your code is running on all your CPU cores, right? Wrong. Or at least, not in the way you'd want.
Programming Guide to Enums in the Python Programming Language Enumerations (Enums) provide a powerful way to represent a set of named values. Enums bring clarity, maintainability, and readability to code by replacing numeric or string constants with more meaningful named constants. The most common way I see people use enums is in roles in a web application such as
Programming Python's async/await: How It Actually Works and Why You Need It asyncio isn't magic. It's a while loop that checks a queue. Once you understand the event loop model, async/await stops being confusing and starts being the most useful tool in your Python kit. Here's the mental model, the real code, and the mistakes that will ruin your day.
Programming Async Timeouts with CompletableFuture: Fixing Blocking Java Code the Right Way 1,000 threads. All of them blocked on future.get(). That's the production nightmare that forced a full rewrite — and the journey through reactive callbacks, exception swallowing pitfalls, and finally a clean within() utility that handles timeouts without giving up the async model.
Programming Featured Implementing Your Own Garbage Collector in Java: Memory Allocation, Reference Tracking, and GC Algorithms This guide walks through designing a fixed-size memory pool, implementing reference counting with cycle detection, coding Mark & Sweep, Mark & Compact, and Copying GC algorithms, and wiring root object identification and sweeping into a working CustomGarbageCollector class.
