A software-defined radio is a radio implemented with reconfigurable software, which processes the raw samples of a digitized radio signal. With about $20, you can get the hardware from ebay and can capture radio and do whatever we want with the radio stream.

Create mazes that having only a single path between any two cells, one row at a time. The algorithm itself is incredibly fast, and far more memory efficient than other popular algorithms.

After above article, this one is another case to tell us use enum carefully. Poorly handled enums can infect code with fragility and tight coupling like a digital Typhoid Mary.

UUIDs are a popular identifier data type – they are unpredictable, and/or globally unique (or at least very unlikely to collide) and quite easy to generate. UUIDs make the access patterns much more random compared to traditional sequential identifiers, cause WAL write amplification etc. So let’s look at an extension generating “sequential” UUIDs, and how it can reduce the negative consequences of using UUIDs
