A rather geeky/technical weblog, est. 2001, by Bramus
Leveraging the JavaScript YouTube Player API and with a good pinch of CSS on top, Thomas H. Park created this record player for you to play with.
Drop the needle and find your favorite track, more or less. It’s fuzzy and inexact, and emphasizes the continuous listening experience an album can be.
Clever usage of repeating-radial-gradient to create the grooves of the record.
Ahmad Shadeed digs into CSS Logical Properties
The basic idea of CSS logical properties is that we won’t use physical directions in CSS properties. Instead, we will use properties that depend on the direction of the HTML document. Those properties are called logical properties.
As I said before: Exciting stuff. This will have a huge impact on how we write CSS.
sudo using Touch ID
Turns out it’s possible to authenticate with sudo using Touch ID, as per this (old) tweet by Cabel:
Pro MacBook Pro Tip: have a Touch Bar with Touch ID? If you edit /etc/pam.d/sudo and add the following line to the top…
auth sufficient pam_tid.so
…you can now use your fingerprint to sudo!
— Cabel (@cabel) November 16, 2017
Note that this will work against when SSH’ing into your machine, and then trying to run sudo:
(Important caveat/warning: if you SSH into that machine, you will NOT be able to sudo, as your fingerprint cannot travel through SSH. 😜)

If you set this up, do realize that anyone who can access your account using their finger (*) can now also do wrong things.

(*) It’s possible to add more than one fingerprint to Touch ID.
#macOS Tip: You can add extra fingerprints to Touch ID
☝️ I've added both my index fingers. I can unlock with left while my right hand is resting on the mouse
👨👩👧👦 They don't need to be your fingerprints. One could add the family's fingerprints

In addition to my 2 index fingers, my wife can also access my computer using Touch ID.
outline-offsetIn this demo Kevin Powell created some buttons that — so it seems — have animated borders. The trick however, is that it’s not the borders but the outline that’s being animated.

Over at web.dev Thomas Steiner has published a series of posts on Mini Apps.
Mini apps are small apps that require a super app to run. They are built with (“dialects” of) the web technologies HTML, CSS, and JavaScript. The runtime of a mini app is a WebView in the super app, not the underlying operating system, which makes mini apps cross platform.
The series consists of 4 main sections:
HTTP is fundamental to modern development, from frontend to backend to mobile. But like any widespread mature standard, it’s got some funky skeletons in the closet.
Some of these skeletons are little-known but genuinely useful features, some of them are legacy oddities relied on by billions of connections daily, and some of them really shouldn’t exist at all. Let’s look behind the curtain.
Did know about that Expect: 100-continue header — and even found a bug in curl handling an intermediary HTTP 417 response — but most of the stuff — such as the HTTP Trailers — were new to me.

Past weekend Lou Ottens — inventor of the Casette Tape while working at Philips Hasselt (Belgium) — passed away at the age of 95. Sharing this Greensock-powered SVG Animation by Chris Gannon seems very timely.

Anyone got a pencil? 😅
blurhash-to-css
If you want to display Blurhash Placeholder Images on your site you need a JavaScript solution to do so. The blurhash-to-css package bypasses that, as it allows you to convert a Blurhash to a set of CSS properties that need to apply.
import { blurhashToCss } from "blurhash-to-css";
const css = blurhashToCss(
"eCF6B#-:[email protected];nmIoWUIko1%NocRk.8xbIUaxR*^+s;RiWAWU"

Installation per NPM:
npm install blurhash-to-cssEarlier this week SpaceX’s SN10 rocket took off, ascended to ±10km, and then after a free fall in the horizontal position turned vertical again to successfully land (only to explode a few minutes later).
While you can rewatch the whole thing online I’m more fascinated by this composite photo by Jack Beyer, visualizing the trajectory:
This is a composite image of SN10's launch and landing. I set this camera to shoot one frame a second, threw out any overlapping shots and stacked them all so we can see the trajectory better. @NASASpaceflight

Date in JavaScript with Intl.DateTimeFormat
Phil Nash walks us through using Intl.DateTimeFormat to format a Date to a specific timezone and format.
const shortcutFormatter = Intl.DateTimeFormat("en-AU", {
timeZone: "Australia/Melbourne",
timeStyle: "long",
dateStyle: "short"
});
shortcutFormatter.format(date);
// => "22/2/21, 5:05:52 pm AEDT"How to display dates in your user’s time zone with the Intl API →
