Willy Tarreau's stuff

Background For quite some time I had been submitting tasks to LLMs via llama-cli (natively) or llama-server (API), both from the excellent llama.cpp project.

I recently stumbled upon this llama.cpp fork which supports AMD Radeon Instinct MI50-32GB cards ("gfx906").

A well known story All those who run a small infrastructure at home know this problem.

In the previous synthetic comparison between ebtree and cebtree it was quite clear that performance varies quite a bit between key types, key distribution, lookup-to-update ratio, and tree type.

Background This is a follow up for the previous article on CEB trees.

Those who often hear me discuss about my week-end projects have been accustomed to hearing about deuterium fusion (that's for another post), laser engraving, and the compact version of the ebtrees, aka compact elastic binary trees, without knowing all the…

Background There are plenty of nice devices these days designed around ARMv8.2 SoCs such as RK3568 or variations around RK3588.

Baby steps are important Four years after I wrote about some improvements brought to my Eleksmaker laser engraver, I made quite a lot of progress on multiple fronts.

Background Two weeks ago, in early May, Tom Cubie of Radxa asked me if I would be interested in testing their new ROCK 5 ITX board.

Optimizing the shelf life of battery-powered devices Background For a few years now I've been placing small lithium batteries in a lot of devices, including a digital camera, a multi-meter, an RC car remote controller, a table vacuum cleaner, a few UPS et…

Background Back in April, the hardware news site cnx-software featured a very nice new small Linux board called Breadbee, that was designed and still being developed by one of the site's readers, Daniel Palmer (aka 'dgp').

Background After having successfully built a few tiny USB batteries in the past, I was always left with a bit of frustration about the difficulty to build them.

After starting to use my laser engraver, I found a few points that really needed to be improved.

Abstract I started making my own PCBs at the age of 10, using a pencil on PCB. 10 years later I bought a kit with an UV table, the ferro-chloric acid tank with bubbles and heating, and presensitized copper, but found it very difficult to use for occasional

It all started while following some links...

Background Several years ago I was intrigued by a strange table at the Palais de la découverte in Paris, which was showing randomly moving lines supposed t be traces of particles falling on it.

Purpose After creating the 3rd version of my build farm I figured the cooling was not optimal due to the thermal tape having a non negligible resistance.

Purpose I like to get up early to have more time to work and design in a quiet place.

[this is a follow-up to this article on version 2 of the build farm] Background The MiQi-based build farms had been running very well both at home and at work over the last 2 years.

[this is a follow-up to this article on version 1 of the build farm] Background The first version of my build farm was described here.

Context Being a developer and having built many thousands of Linux kernels over the last two decades, I can say that build time is something which really counts.

Goal A while ago I purchased a Linksys WRT1900ACS-v2 router to replace my aging 15-years firewall (still running kernel 2.4 on an old VIA Eden board!).

Context My digital camera (Canon A2100 IS) uses 2 AA cells as its power source, as can be seen on the photo below from the review site above : This was one of the reasons why I selected this model, because I didn't want to have to discover that the battery

Context From time to time with a few friends we play with these RC cars but the problem is always the same : the transmitters require 4 AA-sized batteries.

What's the purpose ?
