Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

📂 Persistent "pipes" in Linux

In a project I'm working on I ran into the requirement of having some sort of persistent FIFO buffer or pipe in Linux, i.e. something file-like that could accept writes from a process and persist it to disk until a second process reads (and acknowledges) it. The persistence should be both across process restarts as well as OS restarts.

AFAICT unfortunately in the Linux world such a primitive does not exist (named pipes/FIFOs do not persist

# rtorrent_xmlrpc
# (c) 2011 Roger Que <[email protected]>
#
# Python module for interacting with rtorrent's XML-RPC interface
# directly over SCGI, instead of through an HTTP server intermediary.
# Inspired by Glenn Washburn's xmlrpc2scgi.py [1], but subclasses the
# built-in xmlrpclib classes so that it is compatible with features
# such as MultiCall objects.
