Saving tokens also means using existing tools.

In Rails apps with Tramway and tramway-skill, this is all Claude needs to add user creation to the admin panel.

It even took the test from the example in the skill.

Ruby is more effective in terms of token safety

Pavel Kalashnikov — Fri, 25 Sep 2026 15:51:07 +0000

Purely empirically, Ruby feels way more token-efficient for programming.

I spent the last month on a JS project and the past week mostly on Ruby projects.

The difference is obvious. No further details 😄

11 years ago, we ran out of IPv4 addresses.

I wrote a short piece for the IT History Journal about how it happened — and how the internet has kept working ever since.

I'm done with framework building

Pavel Kalashnikov — Wed, 23 Sep 2026 23:19:17 +0000

With this release, I’m done trying to make Tramway a do-everything Rails library.

From now on, it’s simply a Rails admin panel you can get up and running in no time.

We’ll vibe-code the rest anyway.

Tramway 4.0

It’s been a while since I posted gem updates — and there are quite a few:

✅ Rails 7 support dropped
✅ tramway_navbar completely revamped
✅ New tramway_grid — a handy new component
✅ Updates to tramway_table and tramway_chat

Trivia night meets vibe coding.

My wife and I hosted a quiz at our friends’ wedding, but the venue had no projector.

So we vibe-coded a website instead: everyone got the questions on their phones, while we controlled the game from ours.

Claude is asking this. What’s your answer?

The first Android smartphone was unveiled exactly 18 years ago today

Free tokens!

I’ve set up a local model to use with Codex. It runs at about the same speed as Claude with Sonnet at minimum effort.

It definitely does some dumb stuff, but so far I’ve been able to fix all of it with better instructions. We’ll see how it goes.

Why did I choose gpt-oss-20b?

I had Claude benchmark around 20 models on my machine and give me a report comparing execution time and quality.

After 7 hours of testing and reasoning, it concluded that gpt-oss-20b was the best fit for my setup.

I’m going to stick with it for now and see how it performs in actual day-to-day work.

Token safety of deployment

Pavel Kalashnikov — Thu, 10 Sep 2026 02:34:16 +0000

I updated my skill for deployment non-Rails apps with Kamal.

It now uses the --quiet flag correctly. This is especially important when Claude or Codex deploy your apps autonomously, so they don’t waste context on tons of useless logs.

Interactive Linux Timeline

Pavel Kalashnikov — Sun, 06 Sep 2026 17:57:03 +0000

I added an event board to my Linux timeline, with all the events grouped into categories.

I also generated voiceovers for it — there’s no way I’m narrating anything in English with my nasal voice 😊
