If you use LLM to generate metrics just know that you are running on bullshit metrics.

LLM generated code is becoming increasingly difficult to trust: behind the well phrased comments and neat structures lies a huge pile of debt and lies.

We are deep in the “code is cheap” phase.

It’s been a slow month, but here’s another take at the monthly changelog!

Years ago I used to post on twitter every new thing going on in Citybikes.

If you are working on maps, sooner or later you will want to debug if anything in your code is affecting the performance of the rendering.

I do not know who started this trend (possibly apple but don’t quote me on that), or why it makes me so angry — I think it is because starting phrases with “our” puts in a familiar tone that makes you unconsciously engage, despite not coming from a mom &…

One day I attended a talk about multi-agent systems communicating through ZMQ.

Storing historics of bike share information has been a running topic for me.

It happened again.

There’s plenty of reasons to update to the latest versions of sqlite, specifically if you want to use JSON functions and operators.

I am happy to write here that I am starting on a Commons Fund project with NLnet to scale up and develop CityBikes!

For the last five years I have been using bash more and more.

My starting title was “You do not need ansible for simple gitops”, but writing it I realized I was using ansible as a straw man and in reality what I just wanted to trash about was the general complexity of our professional delivery pipelines.

Today I have been trying out the sqlite plugin for wordpress that will reach wp Core on a near future.

Apple’s newest watch, rated up to 100m comes with a depth sensor (usable up to 40m).

On Try-driven development (TDD 2.0), you try running your changes to see if they work at all.

Here is a fun one I got whilst trying to justify why abusing docker compose accepting file inputs from stdin is a very powerful pattern # Bring up services without a command # # usage: # nocmd.sh up -d service_name function _compose { docker-compose -f…

If you are struggling to get Rancher Desktop to pull docker images from a private container registry, this is what worked on my setup.

Nothing screams last decade like CSS centering.

please bring back the monolith.

Using is fine though.

There are many things any git plugin for your editor will give you.

The time was right.

Usually followed by another email with “VERY URGENT”.

Just published vtfmt, a small bash utility to quickly colorize strings without either dragging in a huge library with too much features or having to manually put (and remember) ANSI escape codes.

A cool trick I have not seen applied much (maybe it’s a bad idea, and that’s why) is using bash as a templating language for complex compose yml files. docker-compose is a nifty entry level tool to work with Docker, but it has its own caveats and limitati…

While diving on ANSI escape sequences, it occurred to me it would be fun to do a progress bar by using only the reverse video escape codes ESC[7m and ESC[27m.

Big companies, and indeed most big institutions are made by a silent majority of the defeated. […] They found joy elsewhere, and found distance between themselves and their work. source

Daily standup, monday 1:1, friday retro, backlog grooming, team meeting.

There’s endless cargo cult about bash being a terrible language and how it should be avoided in favor of go and python for any script longer than N lines.

I’ve been busy working on something.

Lo and behold cmdbikes, a client to get bike share information right at your terminal.

Hace dos años publiqué una “auditoria de seguridad” de BiciMAD.

The Polaroid Cube is all fun and games until you see the only way to configure it is through a program for either Windows or OS X.

Tras varios años en CityBikes, cada vez que aparece un sistema nuevo de bicicletas realizo un análisis general sobre el funcionamiento de sus sistemas.

Heads up for a boring, but needed, post on categorization.

Lately I was feeling a bit nostalgic about how the desktop looked when I started playing with linux, and decided that it was time to write myself a Conky config to pimp my laptop.

Essentially, a binary space partition algorithm will recursively divide a surface into two for a number of iterations.

At the last Blue Systems sprint in Pineda I found a mule roaring outside the house.

A while ago I wanted to play the original NES.
