Earlier this year I got my first non-trivial kernel patch merged.

For a long time I’ve had this goal of getting into Linux Kernel development.

I’ve recently started running Linux on my local machine and decided to play around with Nix in order to avoid having to install a bunch of dependencies globally on the system.

System administrators often use load averages to quickly assess whether a server is overloaded.

As 2018 is coming to and end, I have decided to review my year.

I’ve decided to learn how the Go runtime allocates memory and this is the first in a series of posts that are going to cover what I learned (and also the process itself: how I learned).

Developers running their apps on tsuru can choose plans based on memory and cpu usage.

Ever wondered how long is your program spending while waiting for I/O to finish?

One of the exercises of “The Linux Programming Interface” chapter 38 is about implementing program, called douser, that should have the same functionality as the sudo progam.

This list contains some of the major conference talks that I did in the past years. 2018 Linux Delay Accounting at Gophercon (Lightning Talk) [Slides] [Video] Understanding Go Memory Allocation at Gophercon UK [Slides] [Video] Entendendo Alocação de memór…

This past week a tsuru user was having a problem in one of his apps.

Chapter 7 of “The Linux Programming Interface” is about memory allocation.

Following my read of “The Linux Programming Interface”, I came across the concept of “file with holes” or “sparse files”.

I’m currently reading “The Linux Programming Interface” and I intend to use this blog as a way to share what i’m learning (to make sure I’m actually learning).
