This post is annectodic, but I figured it could still be helpful in some way, so here I go.
Classic story. At work, the CircleCI CI/CD pipeline of the project I work on, as time went by, became slower and slower. Recently, it reached a bit over forty minutes. I worked on it and brought it back under ten minutes. Here is what I did.
I’ve been trying and trying to launch a Neo4j instance on the marketplace without success. It always gave me the nice “success” message, but when I went to the EC2 console: nothing!
I finally decided to do it the hard way: manually. First step: select an instance type. I immediately try to select the same low cost instance I had picked in the marketplace (m3.medium) and to my surprise that type wasn’t there.
Adding 1 + 1, I went back to the market place and tried with an instance type that still exists: m4.large… success!
So I don’t know who is to blame here, but here are my 2 questions to the internet:
Why do we get the success message even though it doesn’t work?
Why are unsupported instance types offered in the market place?
I recently deployed a python application in google app engine / container engine. When I went to check the logs, everything was logged at the “ERROR” level even though my application uses python logging properly. As far as I know there are 2 ways to fix that:
Use the stackdriver client, which requires an additional dependency and somewhat binds your program to google app engine.
Format the logs in a way that stackdriver can parse them, which is easily configurable.
If you develop a ton of python applications and you need to test under a lot of different versions, and by a lot I mean overlapping major/minor versions (like 3.5.3 and 3.5.4), then a good option is to use pyenv. Along with tox, you can easily test your application against various major/minor versions.
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.
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.
