Taras' Blog on AI, Perf, Hacks

We live in the age of software as a service, secret keys are everywhere.

I relax by programming.

I decided to write down some thoughts on agentic coding and why it’s a very hyped wrong turn.

I read a lot, blogs, papers, news, etc.

It used to be that blogs all had RSS feeds.

I’m switching my blog over to a new hugo theme.

tldr: GitHub is where most CLI tools live. eget is a tool that makes it easy to download and install their binaries.

If you’re happy reading on your laptop or Apple device, you can skip this post.

I needed a way to do some programming while offline.

TLDR: chatcraft.org is now smooth as butter and maximally performant thanks to throttling LLM chat-completion rendering via requestAnimationFrame().

I read a lot.

I have an intermittent issue where one of my machines on a specifc network seems to be operational locally on network but not accessible over netbird some of the time.

2025 Disclaimer: I used AI to write some of this blog post.

libkrun + krunvm Github randomly recommended me libkrun which is a library backing krunvm.

I have been working with Python a lot more recently, and it feels like I spend more time fighting packaging than writing code.

13 GiB/s per core!

I’m gonna start a column on cool blog posts I found, that got 0 or minimal traction.

The Problem Ukraine had a lot of power outages due to Putin’s bombing of our power infrastructure, I needed to switch to fiber + battery-backup to continue able to able to work.

TLDR: I prompt-engineered the system prompt in chatcraft to turn it into a github analytics tool: github analyst chat.

chatcraft.org is my open source project for working with GPT.

George Holtz (geohot) just raised $5M for tinygrad and plans to sell a $15,000 Machine Learning AMD Epyc box with AMD 7900 XT video cards.

Ah, the world of software!

I would like to introduce ChatCraft.org: a developer-focused, open source chatgpt frontend.

https://github.com/thegpvc/gpt-aria This was the most interesting prototype I’ve explored in my career so far, and I want to thank TheGP for sponsoring this project.

Cloudflare Pages 😍 I got into Cloudflare pages because it lets you host static websites with all the latest optimizations conveniently and for free.

TLDR: ZFS free-space reporting is a lagging indicator.

Previous blog post on how to trace Firefox IO using bpftrace via official page_fault_user tracepoint left me a bit unsatisfied with how complicated it turned out.

Modern browsers are some of the most complicated programs ever written.

My current employer does a lot of really cool systems work that’s covered by NDAs.

This post is about minimizing amount of disk IO and CPU overhead when reading Zip files.

About

In my previous post I made an argument that a modern phone is only as fast as the slowest component: ability of NAND to handle 4k writes.

TLDR: You can predict degree of unresponsiveness of a phone via random-write-4k benchmarks.
