Use case : Imagine we have just created a project with composer create-project awesone-project (currently V0.2). 2 weeks later, there is a new release (V0.3). How to update your project ? Since composer update only updates the project dependencies, it is not what we are looking for. Composer doesn't know about awesome-project since it's not in our composer.json.

After trying many git solutions, I've come to this :

git archive --output=changes.zip HEAD $(git diff --name-only SHA1 SHA2 --diff-filter=ACMRTUXB)

This command will check for changes between the two commits and ignore deleted files.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Some links from twitter on the topic of parsing PSD files (haven't looked into them in details). PSD include a flattened rasterized image so this is easy to load if that's the only thing you need. Most software / librairies have support for extracting this flattened data (e.g. stb_image.h does).

However if you want access to individual layers, render non-rasterized layers, emulate every photoshop features, extract or apply effects with more granularity, more code is needed. May range from easy to lots-of-work depending on what exactly you need.

As far as I know there isn't a trivial stb-like ready-to-use C++ library to do that sort of things. Posting all links here. Some are probably bloated or hard to use into your project, some lacking features.

TODO: Actually look into the pros/cons of all those.

Zero downtime deploys with gunicorn

Below are the actual files we use in one of our latest applications at Agora Games to achieve zero downtime deploys with gunicorn. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Salient points for each file:

gunicorn.py: The pre_fork function looks for gunicorn's old PID file in the proper file and sends the proper QUIT signal to the old process once the new process is running.
sv-gunicorn-run.jinja: This is the runit template we use in our Salt-managed infrastructure for handling the application process management. You could just as easily convert this to a non-templatized version.

	Well, they could've packed it a bit better, but hey, it took 50 minutes to
