When adapting an example qtile config¹ that used volume keys (XF86AudioRaiseVolume etc.) discovered that I can lock the function keys by pressing <Fn-Esc>. Then a LED turns on, and all the F-keys become function keys.

(Or the opposite, I guess, with default BIOS settings).

Wanted to show the currently active taskwarrior task (220209-1901 taskwarrior getting currently active task) in my statusbar.

Github had helpful discussion¹ that led me to this qtile widget code:

widget.GenPollText(
	update_interval=1,
	func=lambda: subprocess.check_output("path/to/my/get_tasks.sh").decode( "utf-8").strip(),
),

that runs this shell script:

#!/bin/bash

task  rc.verbose=nothing rc.color=off a || true

The || true bit makes sure the return code is 0. Taskwarrior returns 1 if no tasks are shown, in this case - if no task is in progress.

Adding a semi-random number of X after each character of a password is better than giving no output a la linux sudo (bad UX) or writing a single * (unsafe).

Not allowing pasting in the password prompt, then creating weird complex first-time passwords with Os and 0s is worse than both.

Pycharm was slow. Googled for stuff, removed extensions, gave it more memory etc.

Solution from Everything - JetBrains YouTrack:

rm .cache/JetBrains/PyCharmCE2021.3/icons-v3.db 

Deleting icon cache made all menus etc. fast.

Fascinating.

FUNSD is a “dataset for Text Detection, Optical Character Recognition, Spatial Layout Analysis and Form Understanding” and contains annotated forms. Initially I saw it when looking at HF layout datasets¹.

ralphbean/taskw: python taskwarrior api is a Python lib to talk to Taskwarrior, by default through the import/export functionality.

Looks really neat and is a better way to parse the tasks for my statusbar than my planned “read and parse the shell output of the cli command”

Setting up the poetry environment

Create a new project, point it at the folder with the sources, and instead of trying to use an existing poetry environment, just create a new one. It will use the same virtualenv as usual when running poetry shell inside that directory. Nice!¹

The project uses ./src/package_name layout (220105-1142 Order of directories inside a python project), which created issues in the editor (tests and files run fine though). Fixed by adding ./src as Source Root, then it parses all imports as packgae name

Setting up black

Black as external tool

Official Black instructions for Pycharm worked for me: Editor integration — Black 21.12b0 documentation

Creating a binding for black in ideavim

This was tricky! I found a really nice post² that showed how to spawn vim from ideavim. I tried following its example but

nmap <leader>f :action Tool_External_Tools_black<CR>

didn’t work.

The post mentioned running :actionlist inside the editor to get the list of all available actions (I used to rely on a github gist for that!). Well, would you believe, External Tools has a space inside it.

So the correct line is:

nmap <leader>f :action Tool_External Tools_black<CR>

Wow. …Wow.

In any case works now!

NLP Course @ lena-voita.github.io

(Ty AA for the link!)

This is a really nice course covering the basics of NLP, putting it here for now, until I finally finish setting https://serhii.net/links/ up.

Covers:

• Word Embeddings
• Text Classification
• Language Modeling
• Seq2seq and Attention
• Transfer Learning

After enabling “strict” newlines for markdown/hugo conformity I had to decide whether newline would be two trailing space or a single backspace (Line breaks in markdown)

Backspaces didn’t work out, so whitespaces it is - how to make them visible when editing?

Obsidian forum¹ provided this wonderful snippet:

.cm-trailing-space-new-line, .cm-trailing-space-a, .cm-trailing-space-b, .cm-tab{
  font-size: 0;
}
.cm-trailing-space-a::before, .cm-trailing-space-b::before, .cm-trailing-space-new-line::before, .cm-tab::before{
  content:'·';
  color:var(--text-faint);
  font-size: initial;
}
.cm-trailing-space-new-line::before {
  content:'↵';  
}
.cm-tab::before {
  content:'⟶'
}

Works!

(And shows tabs as bonus, perfect.)
