List of useful software

This is the software I like to have on various platforms, and is a work in progress (and so may morph wildly over time according to my personal whims) that I've started mostly for my own use. Recently I used this list in rebuilding my personal workstation after an awful day. Documentation saves (as do backups)!

Linux desktop

My personal workstation and laptop are currently running Ubuntu Desktop 22.04 LTS, moderately tailored for my own use.

Installation Sources and Methods

I prefer the latest vendor official packages or binaries when I can can find them (except where it would be too disruptive: like when they overwrite critical dependencies), but distro packages still form the backbone of my software loadout. The traditional packaging systems (apt for .deb under Ubuntu, and dnf for .rpm under RedHat) can be frustrating to work with, but the systems that seek to replace them (flatpak and snap) are not a panacea by any means (both continue to have trouble with CLI integration

Integralist

There are two 'types' to be aware of with a quickfix window:

1. entry: the actual line content (e.g. :grep foo will show a specific line that matched within a file).
2. file: the actual file itself (e.g. the path to the file that contained the match).

To replace content using vim (via the quickfix window) you need to choose whether you want to apply the change via the quickfix 'entry' or via the 'file' as a whole.

If you use cdo, then your 'action' (i.e. how you're going to replace content) will be applied to every entry in the quickfix window.

If you use cfdo, then your action will be applied to each file in the quickfix window.

Visualising recursive function calls in Elixir

For SICP Exercise 1.14 in Elixir, we'll first implement the count_change/1 function, which calculates how many different ways there are to make change using half-dollars (50 ¢), quarters (5 ¢), dimes (5 ¢) and pennies (1 ¢) for any given amount of money.

iex -r counting_change.exs
Erlang/OTP 23 [erts-11.0.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]

Some useful custom text objects for vim

Collection of my custom text objects I use quite often.

Numbers

Put it into your .vimrc:

premek

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.
#
# Also see:
# - imv from renameutils
# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)

Wow! Fantastic conference. I'm sure at the end we'll have a nice summary, so I'm not going gush too much.

But I must admit, I always enjoy these conferences, so thank you to everybody involved.

How many people have seen me speak at a previous elixir event? Oh, a fair number. «How many have heard me speak» twice?

All right, so the ones that have seen me speak are kind of nervous right now.
