Communication Disorder Edition
- Capturing composite video with a radio receiver.
SDR is software-defined radio - using programmable digital logic in place of the traditional analog circuits. VHF is just another frequency, and video is just another radio signal. With a high enough sample rate, all things are digital.
- The Font in Yellow. (Gizmodo)
The story of a typeface so terrible and beautiful that some idiot tried to drown it in the Thames.
- Thread support has landed in Crystal. (GitHub)
Up to now, Crystal has supported concurrency by full operating system processes, each with their own memory space, and fibers, which are co-operative and share a single execution thread. With full thread support you can distribute fibers across threads so that spawning lightweight workers is still incredibly fast but can also take advantage of multiple CPU cores.
Downside is that you require locks for some simple datastructures that were safe to share with fibers alone.
This was one of the two milestones they needed to pass before declaring a 1.0 release; the other being robust Windows support. It runs fine on WSL right now... Unless you're using memory-mapped files, in which case it freaks out and dies. But that's not Crystal's fault and is supposed to be fixed in WSL 2.0.
- DigitalOcean offers managed database instances for PostgreSQL, MySQL, and Redis. (DigitalOcean)
I understand the first two. Setting up a SQL database cluster is fiddly at best. But Redis? Not only is it dead simple, but it has completely different hardware requirements to MySQL or PostgreSQL, and yet DO's configurations are identical.
Managed PostgreSQL, MySQL, MongoDB, Elasticsearch, or RabbitMQ clusters, sure, go ahead. But spend half an hour and learn to run Redis yourself.
Perhaps if she used Doves Type?
