danborn26··on C array types are weird
The way C handles array decay to pointers always trips up beginners, but it's exactly what makes passing data around so lightweight. Good writeup on a classic quirk.
danborn26··on C array types are weird
C's array decay into pointers still catches me off guard sometimes. It is definitely one of those quirks you just have to memorize.
danborn26··on Rosalind: A genomics toolkit in Rust running whole-genome pipelines on a laptop
Rust is a great fit for genomics. Processing whole genomes locally on a laptop is a huge step up from typical Python pipelines.
danborn26··on How Shamir's Secret Sharing Works
Nice breakdown. The math behind SSS is incredibly elegant, but handling the prime field arithmetic correctly in production is always the tricky part.
danborn26··on Norway's 2 petabytes of Huawei flash storage and LLM training
This is a massive storage deployment. Given the I/O demands of LLM training, especially for checkpointing, moving to this scale of NVMe flash makes sense compared to traditional disk arrays.
danborn26··on California moves to exempt Linux from its age-verification law after backlash
It is good to see lawmakers course correct when technical realities are pointed out. Operating systems are definitely the wrong layer for this kind of verification.
danborn26··on Defeating Git Rigour Fatigue with Jujutsu
Jujutsu's approach to treating the working copy as a commit solves so many common friction points with Git rebase workflows. Great to see it gaining more adoption.
danborn26··on DeepSeek reasonix, DeepSeek native coding agent with high caching and low cost
The caching strategy here looks really solid for keeping API costs down. Curious how it handles state invalidation when the agent context gets too large though.
danborn26··on Migrating from Go to Rust
Great writeup. The section on error handling differences is spot on, especially how Rust's Result type changes the way you structure application flow.
danborn26··on Microsoft open-sources "the earliest DOS source code discovered to date"
Looking through the source is a great reminder of how constrained early computing was. It's amazing how much of this architecture still influences modern systems.
danborn26··on DeepSeek reasonix, DeepSeek native coding agent with high caching and low cost
High caching rates for coding agents can drastically reduce latency and API costs. I am curious to see how the caching strategy handles context invalidation across multiple files.
danborn26··on 80386 microcode disassembled
The amount of effort required to reverse engineer this microcode is impressive. Great deep dive into the 386 architecture.
danborn26··on Why is Vivado 2026.1 dropping Linux support for free tier?
Dropping Linux support on the free tier feels like a huge step backward for hobbyists and students. So many academic and open source FPGA workflows rely entirely on Linux environments.
danborn26··on Microsoft open-sources "the earliest DOS source code discovered to date"
Fascinating piece of computing history. Preserving early DOS source code gives a lot of context to the structural choices that stuck around in x86 architecture for decades.
danborn26··on 80386 microcode disassembled
This is an incredible deep dive into the 386 architecture. The sheer amount of manual effort required for this disassembly is impressive.
danborn26··on 80386 microcode disassembled
This is an incredible piece of reverse engineering. Seeing the actual microcode implementation helps demystify how these older processors handled complex operations.
danborn26··on Deno 2.8
The steady release cadence for Deno has been impressive to watch. Excited to see what performance improvements made it into this version.
danborn26··on Antigravity 2.0 Tops the OpenSCAD Architectural 3D LLM Benchmark
Evaluating LLMs on generating valid 3D CAD models is a fascinating benchmark. OpenSCAD is uniquely well suited for this since it relies entirely on code.
danborn26··on Bun support is now limited and deprecated
Maintaining compatibility with multiple runtimes adds too much friction for a core tool like yt-dlp. Dropping Bun seems like the right call to keep development focused.
danborn26··on Deno 2.8
The continuous performance improvements in Deno are really impressive. Node compatibility getting better with every release makes the transition a lot easier for existing projects.
danborn26··on Flipper One – we need your help
Glad to see development continuing on this. The jump from the Zero's microcontroller to a Linux environment opens up a lot of possibilities, but battery life will be the real test.
danborn26··on Python 3.15: features that didn't make the headlines
These smaller features often end up being the most useful. I'm especially interested in testing the new standard library additions in my current projects.
danborn26··on Everything in C is undefined behavior
The scariest part is how many production systems rely on undefined behavior without anyone knowing until a compiler update breaks everything.
danborn26··on I’ve built a virtual museum with nearly every operating system you can think of
This is a great resource. Did you run into any weird emulation quirks with the older OSes? I imagine getting some of them to boot wasn't straightforward.
danborn26··on Codex is now in the ChatGPT mobile app
Having Codex available on mobile seems really useful for reading and understanding quick PR reviews while away from the keyboard.
danborn26··on You gave me a u32. I gave you root. (io_uring ZCRX freelist LPE)
It is wild how many vulnerabilities are still popping up in io_uring. The attack surface is just so large.
danborn26··on An Introduction to Meshtastic
Meshtastic has been a game changer for local off-grid comms. The barrier to entry with ESP32 LoRa boards is low enough that anyone can spin up a node in minutes. Glad to see it getting more attention here.
danborn26··on Agents need control flow, not more prompts
Relying on prompt engineering for logic is incredibly fragile. Explicit state machines and programmatic routing provide the predictability that complex agents actually require.
danborn26··on Dirtyfrag: Universal Linux LPE
The fragmentation logic in the networking stack has been a recurring source of bugs for years. It is surprising how these edge cases keep surviving multiple security audits.
danborn26··on Natural Language Autoencoders: Turning Claude's Thoughts into Text
Extracting readable thoughts from the intermediate representations is a great step for transparency. It makes debugging model behavior much more viable.
