Not so long ago I got the task of rethinking our build system. The idea was to evaluate existing components, dependencies, but most importantly, to establish a superior design by making use of modern CMake features and paradigms. Most people I know would have avoided such enterprise at all costs, but there is something about writing find modules that makes my brain release endorphins. I thought I was up for an amusing ride. Boy was I wrong.| pablo arias
Last week I bought a Christmas tree. It’s not the tallest, nor the bushiest, the tip is kinda crooked, but it gets the work done. While carrying my new acquisition through the snowy streets, the comforting smell of freshly cut pine reminded me of how much I like trees, specially git worktrees.| pablo arias
In the first part of the series we learned about io_uring by writing a program that reads and parses hundreds of OBJ files from disk. In this second part of the series we will rewrite that program of by making use of C++20 coroutines.| pablo arias
You have made it to the last part of the series. In part 2 we wrote a coroutine-based program that loads and parses a list of OBJ files using coroutines and io_uring. The program still has a big disadvantage: its CPU-bound. Parsing of OBJ files, the most costly part of the algorithm, is performed sequentially on a single thread.| pablo arias
As part of my job I have to deal with quite heavy I/O loads. Multiple times I’ve jumped into a fighting ring facing challenges that demand me to perform thousands of I/O operations in the most efficient way possible. And I haven’t always won. This has directed my attention to more powerful weapons, weapons like io_uring. io_uring is a new asynchronous I/O API in the Linux kernel which offers efficiency and scalability never seen before. With coroutines accepted into the c++20 standard and...| pablo arias

Life is nothing but an endless stream of challenges. The past is made out of fought battles and the future never fails to offer new ones. But, as Marcus Aurelius once said, never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.| pablo arias
Today is the last day of the year. I’m wearing my yellow underwear; it’s a new year’s tradition in this part of the world. People say it shall bring wealth, luck and happiness for the upcoming twelve months. Growing up, I used to consider it silly to wear yellow underwear on new year’s eve. Today I think silly is the one who doesn’t.| pablo arias

I’ve had some free time these days while visiting my parents and little sister in their home in the Colombian Andes. At almost 3000 meters above sea level, it’s a very warm place despite the freezing mountain temperatures; full of nostalgic memories and friendly faces. Chaotic but always welcoming.| pablo arias
It is clear to me that maintaining a popular helper is not worth the time nor the hassle. Without entering into details, this has become an unpaid job I dislike more and more - and I’ve been talking about it for far too long too. As such, this project is now unmaintained.| pablo arias
