Implementing UUID v7 with nothing but crypto.getRandomValues()

Introduction I run a site of small browser-only tools. Each one does a single thing, loads no external resources, and sends nothing to a server. I recently added a UUID generator. Version 4 is a one-liner via crypto.randomUUID(), so there was nothing to build. Version 7 is the interesting one: it is still not in the standard API, and since the site loads no third-party scripts by polic...

Why I Am Rebuilding Enterprise Low-Code for the AI Era

Low-code has become a familiar phrase. Drag-and-drop forms. Generated pages. Approval flows. Dashboards. Internal tools. We have all seen the demos, and many of them are genuinely useful. But after spending years around enterprise digitization projects, I became less interested in how quickly a page can be assembled, and more interested in a harder question: Can the system still be understood, ...

How to control RGB on RAM sticks, motherboards, coolers, graphics cards programmatically with OpenRGB

When I was building my gaming PC a few years ago, I bought a second-hand pair of RAM sticks with RGB lights. It was entertaining to see them glowing and changing colors. I did not bother myself to control them. Some time later, I got sick of gaming and made a decision to rebuild it into a self-hosting server. The PC moved from my table to an under-TV shelf in the living room. And here, glowing li...

Why System Design Interview Prep Is Your Only Moat Against AI

Why System Design Interview Prep Is Your Only Moat Against AI

I build an AI product for a living, and I'll tell you what the models are good at: they write my CRUD endpoints, my Terraform, my test scaffolding, and they'd clear most LeetCode mediums faster than I can read the problem statement. What they have never once done is defend a decision when I push back on it. Ask a model "why Kafka and not Postgres here," then attack its answer twice, and it folds i...

Fixing a UI State Bug in Joplin: Preventing Tag Operations on Deleted Notes

Open source isn't only about building new features—it’s also about making software more reliable by fixing the small issues that affect the user experience. While contributing to Joplin, I encountered a subtle UI state bug that allowed users to interact with tag operations even after a note had been deleted. Although the application didn't crash, the interface no longer reflected the true state o...

A.I Foundational Guideline for Developers

A.I Foundational Guideline for Developers A.I assisted protocol If I were writing guidance for AI researchers, architects, and programmers, I would deliberately avoid beginning with code. I would begin with foundations. The greatest systems are rarely limited by syntax. They are limited by the assumptions embedded before the first line of code is written. Here is what I would propose. A Founda...

How I Built a Free JSON to Excel Converter That Handles Nested JSON

If you've worked with APIs, you've probably received JSON responses that needed to be shared with non-technical users. While developers are comfortable reading JSON, most business users prefer Excel. I often found myself converting API responses into spreadsheets for testing, reporting, and debugging. Existing online tools either had file-size limits, required sign-ups, or struggled with nested J...

Building a Compiler from First Principles

The moment I wrote my first program, I knew I wanted to build a programming language. But how are languages made? How did these carefully arranged magic spells become instructions a machine could execute? For a long time, compiler construction was my main technical obsession — and it still is. I devoured anything I could find about compilers, intermediate representations, parsers, and LLVM. I wor...

Japan Set a Government Deadline for Its Legacy Code. It Was Last Year.

Every engineer has met a cursed codebase. The file nobody edits without a small prayer. The function with a comment that says "DO NOT TOUCH" and no explanation of why. The module that works, mysteriously, and would apparently stop working if you looked at it too hard. Japan has these too. The difference is age and scale. A lot of the systems quietly running this country — banks, insurers, governm...

Audio Plays on Desktop but Not on iPhone / iPad — The Culprit Is the MP4 moov Atom

Series: Engineering gotchas I put a batch of podcast audio files (.m4a) on Cloudflare R2 and embedded them with a plain <audio> tag. Desktop Chrome and Firefox played them perfectly. But on iPhone and iPad, they wouldn't play at all — tap the button, nothing happens, no error message, console completely clean. The most maddening part: it throws no error. You have no idea where to even st...
