Notes sur la compilation de vim 8 et tmux 2 dans un environnement local.

Recipe: Google App Engine, Cloud SQL and sqlalchemy
Here is a recipe on how I made those thing work together both on a linux development environment and in production. The important thing to remember is: just like recipes for brownies, there are other recipes to achieve the same thing.
The following steps assume you have a Google cloud account with the proper permissions.

La chasse aux dépendances avec docker
On veut compiler une nouvelle librairie dans notre beau code. Le “README” indique seulement 2 dépendances… Par expérience, c’est rare que la liste soit exhaustive.
Voici un truc rapide de la part d’un collègue pour aller à la «chasse aux dépendances» sans cochonner sa machine. Ça implique Docker et linux.
Lecture: The Art of Debugging
Déverminer (déboguer) est, je crois, un sujet sur lequel je n’avais jamais lu jusqu’à maintenant. Travaillant maintenant presque à temps plein sur le projet MLDB, en C++, gdb est un de mes outils de travail au quotidien. Comme la productivité d’un programmeur dépend largement de la maîtrise de ses outils, j’ai décidé d’y consacrer du temps.

Lecture: Machine Learning in Action
Après un peu plus de 3 années passées chez Datacratic, il était grand temps que je m’intéresse davantage à l’apprentissage machine. C’est le livre Machine Learning in Action que j’ai choisi pour me lancer.

Fixing Windows 10 sound issue/noise
For a few months I have been struggling with small sound issues. It’s hard to put words to describe it, but it was like noise/static here and there, more often than not while playing games and rendering 3D.
I tried reinstalling audio drivers but that didn’t fix the issue. Finally, I found a post (to which I lost the link) with the solution.
In Windows 10 power options, I changed the configuration from “balanced” to “performance”.
Lecture: Modern C++ Design
Tel que mentionné dans mon billet de lecture précédent, j’ai lu “Modern C++ Design: Generic Programming and Design Patterns Applied”. Ouch. C’est de loin le livre C++ techniquement le plus difficile/avancé que j’ai lu.

SGE/OGS: Clean your logs
At Datacratic, part of our infrastructure runs in the cloud. Our elastic cluster is managed by StarCluster and job dispatch is managed by Open Grid Scheduler (OGS), a fork of Sun Grid Engine (SGE).
While I was looking at StarCluster’s output to help a new user, I realized there was a lot of timeouts. I dug a bit and found out that the command qacct was too slow. Following the lead, I understood that the said command parses a text file each time it is executed.
After a few years of operations, our main cluster has dispatched over 5 000 000 jobs. The log file parsed by qacct was about 2Gb in size. Tada! A couple of search queries taught me that OGS, in its install directory (<path to ogs>/util/logchecker.sh), has a script, ready to be configured, to rotate its logs. I configured and launched it. The timeouts are gone.
Lesson learned: StarCluster/OGS operators, it is important to configure and schedule that script to run every now and then if you want to keep your operations stable.
