Adventures of a curious cat in the land of programming I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be l…
My roots as a developer are in C and Assembly, and I remember fondly the time spent to learn those languages using Borland TASM or Turbo C under MS-DOS. Those languages, and the technology that surrounded them, forced me to understand the l…
This blog was born as a place where I could share what I discovered while I was learning new technologies and concepts. Remaining faithful to this manifesto, I decided to start writing some posts about Rust, as I recently joined the vibrant…

Designing networks is not an easy task, and while cloud computing removes the hassle (and also a bit the fun) of moving around switches and cables, it left untouched the complexity of planning a good structure. But, what does "good structur…

This post is an introduction to partitioning, a technique for distributed storage systems, and to consistent hashing, a specific partitioning algorithm that promotes even distribution of data, while allowing to dynamically change the number…
In this post I will show you how and why Docker Compose is useful, building a simple application written in Python that uses PostgreSQL. I think it is worth going through such an exercise to see how technologies that we might be already fam…
When you create standard RSA keys with ssh-keygen you end up with a private key in PEM format, and a public key in OpenSSH format. Both have been described in detail in my post Public key cryptography: RSA keys. In 2014, OpenSSH introduced
I can't tell you how many times I have heard this sentence from candidates during coding interviews. What's wrong with this sentence? Nothing, out of context, but let me add this little detail: this is usually the first sentence I hear when…
