Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is

Installing FreeBSD 14.2 on a Steam Deck

Update: A full write-up has been posted on my blog at: https://blog.linh.social/2025/01/11/installing-running-freebsd-on-steam-deck/. The post also includes some corrections and new learnings since creating this gist.

Installing onto the internal NVMe SSD

1. Download and burn a FreeBSD 14.2 amd64 installer ISO from FreeBSD.org
2. Burn the installer ISO on to a USB drive, or use a multi-boot tool like IODD or Ventoy
3. Use a USB dock or hub (Anker PowerExpand or 543 6-in-1 USB hub is what I've been using) with USB power delivery pass-through to connect the following devices:
4. USB-C power adapter

step 1: jailbreak your Kindle

mobileread.com is your best resource here, follow the instructions from the LanguageBreak thread

I didn't really follow the LanguageBreak instructions because I didn't care about most of the features + I was curious to do it myself, but the LanguageBreak github repo was invaluable for debugging

1) Exact regex — Matches major model identifier numbers based on Apple's knowledge base article (more accurate):

^(Mac(1[345]|BookPro1[5-8]|BookAir([89]|10)|Pro7)|iMac(Pro1|(19|2[01]))|Macmini[89]),\d+$

2) Current or higher regex — Matches model identifiers based on Apple's knowledge base article and may match higher versions before this regex is updated (more future-proof).

# First, we need to find our device. BEFORE inserting your USB drive, run the
# following:
diskutil list

# This will output a bunch of info about all of the disk drives connected to
# your Mac. Each entry will have a header in the form "/dev/diskX", where X is
# some number starting at 0. Now, insert your USB drive and run the command
# again. You should see a new entry. Make note of the name (ie, /dev/diskX).

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
