pretalx 2025.2.0 plugin migration notes

In pretalx 2025.2.0, a lot of static files (stylesheets and script files) have changed their name and location. The main reason for this is that our static files had grown for a long time without a lot of structure. As a result, we included a lot of styles on all pages, even when we didn't need them. This made pages larger and page loads slower than they needed to be. Once we started the cleanup, we decided to also move files to a more consistent naming and directory scheme. Sorry.

Please also note that pretalx now does not support SCSS out of the box anymore. If your plugin requires SCSS files to be processed, you will have to make sure that they are processed to CSS files.

Django's template-based form rendering: thoughts and pains

Short (well, I tried) collection of thoughts and impressions after moving to Django-native template-based form rendering with pretalx, my ~medium-sized(?) Django project.

When Carlton threatened to read my code (shock, horror), I decided to just write up my impressions, and a gist/pastebin/etc seemed the right format, cuz this isn’t polished enough for a blog post, and also way not constructive enough.

Man page browser comparison

There are a bunch of man page browsers available online. They have different data sources, feature sets, and disadvantages, so here is a short comparison table:

Name	ls man page	No Trackers/Ads	Clickable Headings	Links²	ToC¹	Local Search	Noteworthy
Arch manual pages	ls

	# Use: wrap methods:
	# @breakpoint_on_query()
	# Or use as `with breakpoint_on_query():`

	from contextlib import contextmanager
	@contextmanager
	def breakpoint_on_query():
	from django.db import connection
	def instrument(execute, sql, params, many, context):
	# Optional: match only specific queries, e.g.

	def defuzzy(message):
	import pathlib, polib
	pofiles = list(pathlib.Path(".").glob("pretalx///django.po"))
	for path in pofiles:
	po = polib.pofile(path)
	entry = po.find(message)
	if entry and entry.fuzzy:
	entry.flags.remove("fuzzy")
	entry.previous_msgid = None
	po.save()

	[zammad]
	token = secrettoken
	url = https://my.domain.com

	[pushover]
	user = secretusertoken
	app = secretapptoken

	import json
	import sqlite3
	from datetime import datetime

	import requests
	from tqdm import tqdm

	BASE_URL = "https://code.djangoproject.com/jsonrpc"
	DJANGO_MAX_TICKET = 33562

	import sqlite3
	import sys


	def usage():
	print("Usage: covsource.py <file> <linenos>")
	print(" e.g. covsource.py foo/bar.py 14,15\n")
	print(" or covsource.py foo/bar.py 14-27\n")
	sys.exit(1)

	import os

	from django.http import Http404, FileResponse


	def get_static(request, path, content_type):
	path = os.path.join(settings.BASE_DIR, 'pretalx/static', path)
	if not os.path.exists(path):
	raise Http404()
	return FileResponse(open(path, 'rb'), content_type=content_type)
