Nginx Reverse Proxy

There’s more than one way to configure a server: some are complex, some simple, some static, and some dynamic. I’ve definitely become a fan of using nginx to reverse proxy Docker containers to a specified subdomain e.g. container.yourdomain.com. I spent a lot of time in the past tweaking nginx rewrite rules to give a dynamic feel while keeping the simplicity of a static config file. I recently discovered jwilder’s versitile docker-gen which listens on the Docker sock and updates config files based on the Go text/template language. Continue reading

10 Nim One Liners to Impress Your Friends

My friend sent me the 10 Swift One Liners (referenced at the bottom) which inspired me to try it out in Nim! Like many Electrical Engineers, I cut my programming teeth on “low level” languages like standard ANSI C w/ GCC compiler, x86 assembly, Motorola HC11/HC12 assembly, and even a little GW/QBASIC! But fast forward a few years and projects start requiring GUIs, communication involving marshalling data into a specified format and HTTP requests, and project teams consisting of more than one person touching the code base.
