RESTful API best practices guide - by Shai Yerushalmi

Web API’s is a web development architecture which decoupling the client GUI from the database and the server’s logic. This architecture enables to serve the same interface to multiple clients running on various platforms. Also, the same application can communicate with multiple interfaces.

REST stands for Representational state transfer and its a stateless protocol over HTTP that provides the interactions with the resources stored in the database which contains four basic CRUD actions - Create, Read, Update and Delete.

Each CRUD interaction can be defined by combinations of the following:

Equal widths

Using Raspberry Pi Camera with ffmpeg

Capturing video from the rpi camera with ffmpeg can vary from less than 5% to 100% of the CPU (rpi zero) depending on ffmpeg using the hardware acceleration or not.

On many github issues one finds the suggestion of using h264_omx codec to use the gpu - but it does not ship with the default ffmpeg on Raspbian.

Instead I found that one can use the v4l2 driver provided by raspbian to get hardware accelerated h264 output. Also setting the video size will save one from using a (cpu) scale filter.

ffmpeg

capture h264 video from rpi camera

Uses tree along with a .gitignore file to filter results. Defaults to ignoring node_modules if no .gitignore can be found in the current directory or in the git repo's root directory.

Would be cooler if we knew exacty where .gitignore files made a difference. Even nicer if the output showed the status of files in Git (modified, unchanged, new, deleted etc).

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm
