Exponential backoff with jitter: 64 of 100 LLM calls still failed
Originally published at tensorust.com . TL;DR: I fired 100 LLM calls at once into a rate limiter that refills 10 requests a second, using the defaul…

34.8k Stars Won't Put GTA VI on Your PC. Here's What AnyPS5 Is Actually Doing
Seeing GTA VI run on a PC before the official port would be a spectacular way to end the console exclusivity argument. So a project that promises to…
SLX RadioTwin: industrial radio propagation studies with C++ and Qt
Silicon LogiX introduces SLX RadioTwin , a desktop demonstrator for studying radio propagation in a three-dimensional industrial plant. The project…
The Flush Printed a View After the Owner Died
A green debug run does not prove a view owns its bytes. Release can reuse that stack slot before the flush reads it. I start every split-brain crash…
Build the Patch as a Stranger: A Consumer-Link Gate for C++ Codegen
A packaging job can fail on a Thursday morning while the eval board stays green. In that pattern, the candidate patch repairs normalize() inside one…
UE5 Shader Optimization: Materials, Custom HLSL, and Global Shaders with RDG
When a material graph grows in Unreal Engine 5, it is tempting to ask: would writing HLSL directly make it faster? Would implementing the shader in…

The rules I build by

DSCI pipeline to build c++ project using cmake
📁 Repository layout . ├── .dsci/ │ ├── jobs.yaml # pipeline definition │ └── build_job/ # ── Job 1 – Build & package │ ├── config.yaml # default…
In 2018 I hand-wrote a C++ deep learning framework so I'd never pad a batch. In 2023 LLM serving landed on the same structure.
There's a sentence in the README of a library I wrote that I've been thinking about lately: "To summarize, we believe that Padding-free Dynamic Batc…
I could not understand Express, so I wrote my own
Middleware chaining made no sense to me, so I rebuilt it in C++. A year later the profile said the slowest thing in my server was a map I rebuilt on…
Store Load Reordering: x86 vs ARM64, and the Bug Intel Was Hiding
Here is a bug report that keeps recurring, in different words, every time a team moves to ARM: "the same code works on our Intel CI and on the devel…

The Map Dropped a Key When Two Expiry Times Matched
A C++ map can drop a live cache entry. One <= in a comparator is enough. I forced a timestamp tie and watched a key vanish. Would you have caught…
The Compiler as Validator: When a Free Model's Wrong C++ Is Still Cheap
A free model will write wrong C++ template code. That is not a problem when the compiler is the validator. In this experiment, a free model wrote te…
How to Change Themes with the Operating System in a Qt App
It turns out, I got the timeline wrong. The first bit of work I did on Packet Sender was to test light mode. See, Dan Nagle, creator and maintainer…
Why I Rewrote My Flutter Tray App as a C++ Daemon
I built a screen-capture tool for Linux in Flutter. Tray icon, global hotkey, region select, done — that was the plan. It worked, right up until thr…
I built a small C++ game engine so an AI IDE could touch the whole thing
Originally posted on Medium . I wanted to make a game. I also wanted the AI IDE on my desk to edit the whole running process, not just the scripts.…
AArch64 Register Conventions: What Survives a Function Call—and Why
What happens to a register when you call a function? On AArch64, the answer isn't "the CPU saves it." When you call a function, the CPU doesn't look…
Auditing Agent Patches: Property Checks, Fixture Locks, and Expiring Flaky Freezes
I review agent patches as an auditor, not a reader. A reader asks whether the code is readable. An auditor asks what the patch promised and how a vi…
A Green Suite Can Still Lie: Mutation-Test Your Fixtures Before You Trust an Agent Patch
An agent patch can pass every fixture in your repository and still be wrong. The fixtures are part of the oracle, and fixtures can be lazy. If the e…
Qt 5 to Qt 6 Migration Guide for 2026
Qt 6 is a major version, and migrating a real Qt 5 application to it is more than a recompile. The framework was modularised, the build system shift…
Mutation Testing as a Merge Gate for Agent-Written Tests
An agent patch that passes its own tests is a baseline, not a verdict. The same model wrote the code and the tests, so both share the same blind spo…
The Coverage Loop: Turning Free AI Tokens into Verified C++ Tests
Unit tests are boring. Coverage is not optional. I asked a free AI model to write my tests. It failed. Then I built a feedback loop. Here is the res…
Case Study: A Free Model Wrote a C++ Tree Hasher. The Reference Oracle Found Three Bugs.
Conclusion first: a free model drafted a working C++17 directory hasher in one pass. The draft compiled, ran, and was still wrong. A differential te…

A Free Model Endpoint Returned 200 With an Empty Body. The Fix Was a Lease, Not a Retry.
A realistic failure mode starts with a team that runs a nightly triage job on a small free server. The job groups stack traces from three services.…
I Inherited 60,000 Lines of Undocumented C++. I Read It With an AI and Assumed Every Answer Was a Lie.
Three months ago a colleague left, and I inherited his project: roughly 60,000 lines of C++17, no design docs, comments that mostly said // TODO: cl…
