M'colleague Charles has introduced me to the most spectacular phrase - "Time To 200". That's a measurement of the length of time it takes a new user to go from signing up to your API to getting their first HTTP 200 response. Think about the last time you started using a new API... Fill in a tediously long registration…

Setting up a Raspberry Pi with 2 Network Interfaces as a simple router
I needed a very basic 'Internet sharing' router setup with one of my Raspberry Pis, and I thought I'd document the setup process here in case I need to do it again.

Considering how important “undefined behavior” has become to C semantics and the ISO/IEC JTC1/SC22/WG14 Committee, the lack of any reference to it in the K&R ANSI book is notable and the description in the 1999 C Rationale was quite modest.

“I Could Rewrite Curl”
Collected quotes and snippets from people publicly sneezing off or belittling what curl is, explaining how easy it would be to make a replacement in no time with no effort or generally not being very helpful.
