Intro

This is my website. It is simply updated through a google docs file!

I also have a previous, sparingly used blog here, but I may not really believe everything I say there. Consider this website the most updated one.

My X account: sparingly used, maybe I should tweet more. You can write me on telegram to start a convo

If AI becomes too cheap to meter, our homes will be the biggest target of attacks. Remote attacks I mean. There is no reason to have any IoT device, you “smart” vacuum cleaner included. They don’t work well, and now they are a big target.

Imagine a computer, leveragin the cleaner, and planting something in you home pc. 1year pass, you attache your hardware wallet, unlock it and PUFF your funds are gone: there was a daemon you did not know about

OOPS

It is like that, protect your computers at all costs. Let’s just consider everything on the internet as compromised already. And those things attaching to the internet are compromised as well. How would you protect your keys?

The best hardware wallet is a pc with no wifi and bitcoin core for real:

I have  slow computer an i need a faster one

Deepseek 0731 is making my old devices new again, making things I neve had the time to do. My old samsung phone is now an electrum node. A bad tablet is now…

I like this ability. I like those device as they are “hackable”. Couldn’t do this with my iphone i guess. No abd or similar, and you can’t make apps for that.

Yet deepseek is not letting me break my jade. It refuses to do that. Heh

Opencode is awesome

Is codex good or is the model?

We need harness benchmarks

Nvim is fantastic too

Like the real IDE. With LazyVim it just works. Sure it's bloated or whatever the cool kids say nowadays. Then they use VScode. Still it works, it's fast and has everything

Even rust language server works awesomely, better than VScode from a keyword and UX stand point

Constraining the search space and choose tradeoffs

I love programming and creating sketches. I love to see things happening. LLMs are awesome for it. Just never let them create something human-readable. That is so wrong it will make you lose faith in the whole AI thing

LLMs are for coding, and basic search engines. Some kind of knowledge tourism, that’s it. You can not use them to make decisions, real brainstorming etc. you either know what you talk about, or you’ll get confused. Google Docs, pieces of paper or some kind of e-ink tablet to write are the tools for thinking. You need to know your tradeoffs (kyt). You explore the new field, can’t ask LLMs for “summaries”

Did you really read what an LLM produces in plain english? Have you tried to read something well written like The History of the Decline and Fall of the Roman Empire by Gibbon? I am not an expert, but the latter seems to me real writing.

Gpt 5.6. Sol works very well I must say. Working on consensus right now, simulating basic BFT in case of network problems + byzantine behaviour. Fun weekend project I must say.

Just never let the LLM plan, really. It’s not good. Too much details and too little thinking/overview and understanding of consequences at the same time.

I wonder now if my job is just being a good planner. Writing code is obsolete. Fortunately I am a researcher by training, but can I be an expert in all parts of a project?

Codex is my sysadmin now. Moved me from dwm to hyprland in minutes, and everything works. Created a repo for my dotfiles and it works there too. All that while working. A couple of tmux sessions had everything done for me. Controlled from the phone, of course.

image of bad posture

It helps on a lot of things, and I use it at like 10% of their potential. It feels like re-learning how to use my Linux PC from scratch.

I have been very bearish on LLM last months, mostly for a combination of bad models, bad use on my part and the fact that LLMs simply can not write. I fell for the “knowledge base” thing and produced documents writing meaning less things. Man, you have to really guard that llm, you know? You leave it alone writing a 10 pages “research paper” and you find it sprouting “scaffolding” and “security boundary”  and |invariant” all over the place.

Today another AI-based problem with a piece of Bitcoin infrastructure, after the ColdCard debacle

First entry

Wow! Unexpectedly the thing is working! What a wonderful thing!

It also has autoupdate. I can not believe how easy it was

So easy to update. Never thought about that easiness

The difficulty is in having a VPS now it seems
