Shh: Simple Shell Scripting from Haskell
Summary: GitHub user luke-clifton has created "shh," a Haskell library for simple shell-like scripting. The library enables convenient shell programming in Haskell and works well in scripts and GHCi. It provides functions to mimic the shell environment, making it easy to port shell scripts to Haskell. Shh supports redirection, piping, concurrency, capturing process output, and more. The library requires the threaded runtime and supports Template Haskell for loading executables as Haskell functions.

Why 56k the fastest dial up modem speed
Summary: The 56k dialup modem speed is a result of historical and technical factors. Originally, phone networks were designed with a bandwidth of 3.2 kHz for adequate voice quality. With the introduction of digital communication, voice data was digitized at 8 kHz, resulting in a 64 kbit/s data stream. However, control data needed to be transmitted alongside voice data, so the least significant bit of every sixth byte was "stolen" for this purpose. This reduced the maximum data rate to 56 kbit/s. Actual connection speeds may be lower due to FCC power output restrictions and varying phone network conditions.
