I often find myself looking at some beautiful typography, on my phone. Since there's no easy way to inspect the source, I have to add the url to my to do list, open it on my laptop and go from there.
With the Fontanello iOS Safari extension that's a thing of the past. Select the text, open the extension and voilà: Fontanello shows the typeface, weight and even letter-spacing and features.
Astro's new toolkit for creating documentation websites. Still in beta, but it looks quite extensive.
An absolutely delightful demonstration of an AI assistant tailored to the needs of Geoffrey's family.
There’s a lot of hype these days around patterns for building with AI. Agents, memory, RAG, assistants—so many buzzwords! But the reality is, you don’t need fancy techniques or libraries to build useful personal tools with LLMs.
Or as Tomas Ptacek put it: You Should Write An Agent.
I'm often finding myself being afk for a few minutes, while some process is running. Got to stretch those legs, you know?
I've started using nfty to send me a notification on my phone as soon as a process has completed, so I can actually go ahead and step away without having to check in. And it really couldn't be easier.
First: set up your ntfy account and a topic.
Second: add something like the function below to your .{bash,zsh}rc. Or turn it into a script.
function ping_me () {
local default="FYI: that thing you triggered just stopped."
local message="${1:-$default}"
# $ntfy_topic_url is something like
# https://ntfy.sh/yoursecretishtopicname
curl -sf \
-H "Title: laptop" \
-d "${message}" \
${ntfy_topic_url} \
> /dev/null || echo "Ping failed"
}
Third: use it!
Now running just docker-build docker-push && ping_me means Docker can have some fun while I go grab a coffee, check on the laundry, or walk around aimlessly trying to figure out what I was planning on doing.
Something that always made me wonder: why doesn't the IntegrityError raised by a database (driver) include some actual actionable data?
I don't know. I do know that it doesn't have to stay that way! With Rootcause you'll be able to gather all necessary information when you violate the most common types of constraints in Django.
import rootcause
try:
... # something violates a constraint
except IntegrityError as e:
cause = rootcause.resolve(e, model=MyModel)
if cause.is_check(name="max_amount"):
raise MaxAmountExceeded()
if cause.is_unique(name="payment_reference"):
raise AlreadyPaid()
The goal of Rootcause is twofold: provide more information and eliminate differences between databases.
Rootcause has been tested with recent versions of SQLite, PostgreSQL and MySQL, and requires Django 5.1 or better.
One of the extremely useful snippets I discovered in Evan Hahn's Scripts I wrote that I use all the time is radio.
I cannot work in silence. I need to have something going in the background, preferably classics and not encumbered with too much chit-chat.
Instead of having a browser tab or app sitting there in the background, I adapted Evan's script. It uses mpv, so now I've got a Ghostty tab running in the background instead.
#!/usr/bin/env bash
# Check https://mytuner-radio.com/nl/radio/vrt-radio-2-limburg-402485/
set -e
set -u
set -o pipefail
if [ "$1" == joeeasy ]; then
url='https://icecast-qmusicbe-cdp.triple-it.nl/joe_easy.aac'
elif [ "$1" == radio2 ]; then
url='http://vrt.streamabc.net/vrt-radio2limburg-mp3-128-2845863?sABC=68s94r20#0#r7p08610r6n19o27sn00016q8n8877qs#&aw_0_1st.playerid=&amsparams=playerid:;skey:1761168928'
else
echo "don't know $1" 1>&2
exit 1
fi
exec mpv --really-quiet "$url"
Evan Hahn lists every useful script in his repertoire. I always like to see things like this pop up, just to remind myself that I don't actually optimize every single reoccuring task (yes, that's a bit of a relief).
A JavaScript library for reading, writing, and converting video and audio files. Directly in the browser, and faster than anybunny else.
This would have come in so handy in a previous project. I still need to write a note on that.
Josh goes into detail on how to use linear() as the timing function for your CSS animations.
This may be the silliest post I’ve ever written.
Truth be told: I'm mostly adding this because of the beautiful design.
