I've been integrating AI into my development workflow, but I quickly realized that costs can spiral out of control if not monitored carefully. Premium AI coding assistants with their subscription models and "pro" tiers can easily become expensive-especially for personal and open-source projects where budgets are tight. I found myself needing to track every API call and watch my usage like a hawk.

I don't trust apps with my crypto. Every wallet, exchange, and dapp is a black box. You hand over your private key, click "send", and hope the code does what it claims. So I built my own scripts instead: small, auditable Python programs that I can read and understand completely.

The differences between Stellar and Ethereum force you to confront each blockchain's design philosophy. Here's what I learned building scripts for both.

A while ago I wrote [a blog post about how I created this blog][init-post]. Back then it was [Pelican][pelican-website], a [Python][python-website] static site generator. Then I migrated it to [MkDocs][mkdocs-website] — also [Python][python-website], a bit more modern, better support for my bilingual setup. Now here we are again. Third time.

This is the story of why I did it and how it went.

I have been following Apple machine learning research for a while now and I have been stunned by their Keyframer demo application. I have been trying to replicate the Saturn SVG used in the demo and I think I have come up with a pretty good approximation.

In this article, I will explain why Python Virtual Environments are so cool when you know how to use them properly. I will also show you how to use them the right way.

Today I have upgraded my [Fedora][fedoraproject] server from version 33 to 38 but all did not go as planned.

Today I was confronted with a quite annoying problem. I have a server with a 1Gbps network card connected to a 1Gbps switch. I was trying to backup my data as usual but the transfer was slower than usual. Using ethtool I saw that the link speed was only 100Mbps !

This article describes how to use a SSH CA to authenticate to SSH servers. This is particularly useful when you have a lot of servers to manage and you want to avoid the hassle of managing a lot of SSH keys.

The basic idea is to have a CA (Certificate Authority) that will sign the public keys of the users. Then, the users will be able to authenticate to the servers using their signed public key. This way, you don't have to manage the public keys of the users on the servers, you only have to manage the public keys of the CA. You can also limit the validity of the signed public keys to a certain amount of time or to a certain set of servers and users.

I have a lot of media to watch and I don't want to spend time searching for it, downloading it, renaming it, moving it, etc. I want to be able to request a movie or a TV show and watch it in less than 5 minutes. I also want to be able to watch it on any device, anywhere, anytime.

Now that I have generated by own custom certification chain in the previous article "x509 certificat managment" I need to install the Certificate Authority (CA) on my iPhone.
