<strong>I'm Building a Browser for Reverse Engineers (19 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This article goes over the process of building a custom browser for web reverse-engineering to streamline the process of analyzing browser fingerprinting and anti-bot techniques. The project started with a simple browser extension for hooking JavaScript functions but evolved to use the Chrome Devtools Protocol for deeper access. Eventually, Chromium was forked to create custom events for stealthier instrumentation. The final browser includes features like deobfuscation, property overrides, and automated decryption of fingerprinting payloads.

<strong>How we found a bug in Go's arm64 compiler (10 minute read)</strong>

<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare discovered a race condition bug in Go's arm64 compiler due to high traffic volume. The bug caused sporadic panics on arm64 machines related to stack unwinding, which were initially thought to be rare stack memory corruption. Through deep investigation and debugging, it was found that async preemption during stack pointer adjustments in the `(*NetlinkSocket).Receive` function led to an invalid stack pointer during garbage collection, causing the unwinder to crash.

A study compared the rendering performance of Angular, React, Vue, Svelte, and Blazor JavaScript frameworks. It found that Svelte consistently outperformed the other frameworks in various benchmarks, especially at creating and updating elements. Svelte's performance is due to its reactivity system, optimizing compiler, and binding-based rendering.

<strong>Seeing like a software company (18 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Large software companies prioritize legibility (measurability and predictability) over efficiency. While small companies can thrive with illegible, engineer-driven work, large companies require legibility for planning, enterprise deals, and coordination, even if it slows down individual engineers. To balance this, companies create temporary "zones of illegibility" for urgent problems and rely on informal backchannels.

Devs should test their software's installation instructions on a fresh virtual machine. When doing so, they should document every step taken during the installation process, including installing dependencies, and then transferring that documented history to the README file to guarantee accuracy and completeness.

The rise of AI and LLMs threatens the core identity of programmers as craftspeople. Vibe-coding and specification engineering have turned programmers into operators rather than creative problem-solvers. This shift removes a lot of the joy and fulfillment of programming.

<strong>My First Contribution to Linux (18 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This dev's first contribution to the Linux kernel was adding support for the hotkeys on their 2005 Fujitsu Lifebook S2110 laptop. They go over the process of identifying the relevant driver, studying the code to understand how it handles key events, and modifying it to recognize the media keys. They submitted their patch through the traditional email workflow and saw that it merged into the upstream kernel.

<strong>Why We Need SIMD (The Real Reason) (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
SIMD (Single Instruction, Multiple Data) instructions give performance gains at a relatively low cost by reusing existing CPU infrastructure. This lets a single instruction perform multiple operations simultaneously. The adoption of SIMD has been hampered by the need for software updates to use new instructions. However, recent advancements are helping increase adoption.

<strong>The Email They Shouldn't Have Read (8 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This dev helped Agency B and C transition to an open-source mail stack, angering their current provider, who used hidden clauses in their contract to retaliate. The provider potentially spied on their emails and threatened legal action, preventing the agencies from switching and ultimately raising their costs. Despite the ethical issues, the agencies were unable to break free, showing the challenges of escaping vendor lock-in.
