[Wayback/Archive] Post by @lookitup.baby (Ian Coldwater) — Bluesky on recharge being part of your work
I paid my therapist a zillion dollars to tell me this, so I’m passing it on to anyone else in MN who needs to hear it:
Think of taking time away to recharge not as not doing the work, but as doing quality control for the work. You’re not going to be able to show up to do it well if you’re depleted
The replies add a few other useful tips. Be sure to read the thread on BSKY.
A few days later, this Dutch post basically stated it in a different way:

Seems this is not an easily accessible built-in feature of MacOS: [Wayback/Archive] macos change brightness of external monitor at DuckDuckGo
Basically there seem to be two apps that are most popular:
Lunar is free, but has a fee for some features. MonitorControl is free derived from Lunar, but has less features than the paid Lunar license has and is less often updated.
Both have been developed in Swift and are on GitHub:

[Wayback/Archive] Show HN: Live-updating version of the ‘What a week, huh?’ meme | Hacker News
As a fun evening project, I made a live-updating version of the ‘What a week, huh?’ meme (based on a panel from The Adventures of Tintin comics [1]).
There’s a page for every timeframe:
Current time is determined by a Cloudflare Worker using the request IP (not logged or stored). No JavaScript is sent to the browser.
[1] https://knowyourmeme.com/memes/what-a-week-huh
It was easy to edit the HTML to change the message and CSS for the text dimensions, see the image on the right.
MacOS users will likely recognise the font as it is the Marker Felt font which is included by default on MacOS.

Interesting, but be aware that using it outside a shielded environment likekly is illegal: [Wayback/Archive] Osmo-fl2k – osmo-fl2k – Open Source Mobile Communications
- osmo-fl2k allows to use USB 3.0 to VGA adapters based on the Fresco Logic FL2000 chip, which are available for around $5, as general purpose DACs and SDR transmitter generating a continuous stream of samples by avoiding the HSYNC and VSYNC blanking intervals.
…
- Operating a transmitter with the unfiltered FL2000 DAC output attached to an antenna outside a RF shielding chamber is dangerous. Don’t do it!
