Makes Zsh print a bell when long-running commands finish. I use this in combination with i3 and throw big compile jobs (or whatever it may be) into another workspace to get a nice visual notification (workspace indicator turns red) when it's done so I don't need to waste time regularly checking on it.
#!/usr/bin/env zsh
# This script prints a bell character when a command finishes
# if it has been running for longer than $zbell_duration seconds.
# If there are programs that you know run long that you don't
# want to bell after, then add them to $zbell_ignore.
#
# This script uses only zsh builtins so its fast, there's no needless
# forking, and its only dependency is zsh and its standard modules

Quickly compiling Heirloom Doctools

Each time I re-install a fresh Linux distribution, one of the first things I need to do is to compile the Heirloom Documentation Tools. However some adjustments have to be performed; I write them here in order to recall them later:

  • download the sources from http://heirloom.sourceforge.net/doctools.html

  • type: sudo apt-get install g++ libc-dev bison flex

  • uncompress the tarball

  • enter the heirloom-doctools directory

  • edit mk.config and change three lines:

    • replace INSTALL=/usr/ucb/install with INSTALL=/usr/bin/install
  • replace PREFIX=/usr with PREFIX=/opt/heirloom

GCC compiler optimization for ARM-based systems

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

Writing an OS in Rust to run on RISC-V

(This is a translation of the original article in Japanese by moratorium08.)

(UPDATE (22/3/2019): Added some corrections provided by the original author.)

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

IMAP Specifications

IMAP specifications

(TODO) All IANA registered IMAP capabilities, response codes, keywords, mailbox attributes, the most relevant SASL mechanisms, and other relevant specifications.

  • ⛔️: obsolete specifications that have been deprecated or replaced
  • ⏭️: extensions that have been completely or partially included in [IMAP4rev2].
  • ✨: extensions that are recommended for [IMAP4rev2] servers and clients. The IETF EXTRA WG decided that requiring them as a part of IMAP4rev2 would push the bar to implement too high for new implementations.
  • 🗑: extensions that have been completely or partially deprecated or removed in [IMAP4rev2].
  • 🍋: extensions that are included in the "Lemonade" profile [RFC5550].
