Huffman coding (also known as Huffman Encoding) is an algorithm for doing data compression, and it forms the basic idea behind file compression. This post talks about the fixed-length and variable-length encoding, uniquely decodable codes, prefix rules, and Huffman Tree construction.
When people talk about monetizing, they’re usually talking about some sort of scheme. Because anything that needs to be monetized can’t just be simple. If it was simple, you wouldn’t need a word li…

There are a smorgasbord of database engines out there. From an outside perspective, Postgres is just another on a steadily growing pile of structured data storage mechanisms. Similarly to programming languages like Rust and Go, it's the new and shiny database systems like MongoDB that tend to garner the most attention. On the other hand, more established engines like Oracle or MySQL have a vastly larger lead that seems insurmountable. In either case, enthusiasm and support is likely to be better represented in exciting or established installations. So why? Why out of the myriad choices available, use Postgres? I tend to get asked this question by other DBAs or systems engineers that learn I strongly advocate Postgres. It's actually a pretty fair inquiry, so why not make it the subject of the first PG Phriday for 2017? What distinguishes it from its brethren so strongly that I staked my entire career on it?

Off-The-Shelf Hacker: Lightweight Inter-Device Messaging with MQTT - The New Stack
In past Off-The-Shelf Hacker projects, like the PIR Yard Sensor, data was simply exchanged to/from the ESP8266 with my Linux notebook, using text, over the network. The methodology created one server (the notebook) and one client (the ESP8266 device). While this worked fine for prototyping and getting to know Internet of Things basics, it doesn't…
