Cool, did not know this and used readonly groups (with one writer) for this before: [Wayback/Archive] WhatsApp Help Center – How to use broadcast lists
Via: [Archive] Sylvia on Twitter: “Ik wist nooit van t bestaan van verzendlijsten op whapp. Zusje kwam er gisteravond mee. Ging wereld voor mij open. Ideaal in deze situatie. Gewoon 1 bericht er uit en hele familie en vriendenkring is op de hoogte.”

A while ago I wrote about Figuring out the open network connections for processes ran by python, which explained the TL;DR:
pidof python | tr " " "\n" | xargs -r -n 1 lsof -i -a -e /run/user/1001/gvfs -p
Now I needed thread information as well, so below two examples using ps and pstree. I won’t explain the pidof and xargs stuff here as that was already covered in the above blog-post and I found out that ps already has a built-in way to filter on process name.
The ps solution uses the H, -L or -T argument to show the threads:

Cool that Amnesty International can do a YouTube [Wayback/Archive] Extract Meta Data (Amnesty International).

I wonder if I can write a Bookmarklet for this (it will likely require an HTTP POST request).

This is a follow-up to Bookmarklets for Archive.is and the WayBack Machine to go to the original page.
Archive.is has two kinds of URLs:
You get the first URL both after archiving and when browsing from an archived page to another archived page (if it is not archived you will go the unarchived full page URL).

For my link archive:
Om het aantal zonnepanelen te berekenen, gebruiken wij de zogenaamde “opbrengstfactor”. De opbrengst van uw installatie is namelijk afhankelijk van de windrichting en de hoek van het dak. Het ideale dak is op het zuiden gericht en heeft een hellingshoek van 35 graden.
Voor alle mogelijke situaties kunt u de juiste opbrengstfactor opzoeken in onze opbrengsttabel: download hier onze opbrengst tabel.
U heeft de juiste factor nodig voor de berekening van het aantal zonnepanelen.
Rendement schuinte zonnepanelen
Door de zonnepanelen naast en achter elkaar op het platte dak te plaatsen bestaat het risico dat het ene paneel schaduw werpt op het volgende zonnepaneel. Daardoor is het verstandig ze panelen niet te dicht op elkaar te zetten. Dat heeft tot gevolg dat je niet oneindig veel zonnepanelen op een plat dak van bijvoorbeeld 3 bij 6 kwijt kunt. De minimale afstand tussen 2 panelen is afhankelijk van een enkele factoren. Onder andere de stand van de zon. In de winter staat de zon lager en zijn de schaduwen het langst. Dan is het goed als de zonnepanelen pal op de zon gericht staan.Dit zijn de verschillen in afname in rendement tussen verschillende hellingen van zonnepanelen:
Helling zonnepanelen Afname rendement 35° 0% minder rendement 30° 1% minder rendement 25° 2% minder rendement 20° 3% minder rendement 15° 5% minder rendement Afstand vanaf de rand
Bij standaard afmeting van 99 x 165 cm:
Helling zonnepanelen Hoogte zonnepanelen

Je kunt de volgende afstanden aanhouden bij het plaatsen van zonnepanelen in landscape:
- Bij een 25 graden plaatsing 1,2 meter tussenafstand
- Bij een 15 graden plaatsing 0,7 meter tussenafstand
- Bij een 10 graden plaatsing 0,5 meter tussenafstand
In plaats van een hoge piekopbrengst in de middag, geeft een Oost- West systeem een lagere, maar bredere opbrengstgrafiek zien (oranje lijn).
- Landscape – kan dichter bij elkaar dan portrait
- Minder schuin – kun je meerdere rijen kwijt tegen beperkt verlies
- Oost-West montage – omvormer nodig die meerdere strings aan kan
- omvormer nodig die meerdere strings aan kan
- Oosten: 13 graden
- Zuidoosten: 25 graden
- Zuiden: 35-36 graden
- Zuidwesten: 25 graden
- Westen: 13 graden

I’m not alone in feeling hated by printers and multifunctionals.
I had already seen this 2019 comic [Archive.is] System32Comics on Twitter: “Printers nowadays… “ quite a while ago:
- User: Hey printer, can you please print this document?
- Printer: Low on Cyan
- User: Don’t worry, it’s just a black and white text
- Printer: No fuck you, low on Cyan
Printers and the drivers shipped by manufacturers hate me so much, that I now have the habit of using older printers which are better supported out-of-the-box by modern operating systems, hence this tweet:
[Archive.is] Jeroen Wiert Pluimers on Twitter: “I try to avoid using the software provided by the printer manufacturer. Usually stock PCL or PostScript drivers work fine.… “
Thanks to [Archive.is] Matt Schultz 😷 on Twitter: “Seems about right… … “, I found out that early 2021 Stevie Martin came along with this hilarious video [Archive.is] “when you’re trying to print something”:
And of course the System32Comics version was commented immediately: [Archive.is] Mr. Dubi and Dr. Kan on Twitter: “… “ (:
But also a few other nice comments were made that I had not known of before:
Me: I want to scan something
Printer: Can’t, i’m out of Magenta ink
Me: But i only need a scan… and i’m pretty sure i’ve never used any shade of red on my printed documents :/
Printer: I’m out of Magenta… Also my fixed IP address is 169.25.41.1/24 right?
Me: *cry internally*
“Hey printer/scanner scan this pager for me.
Nah, no ink.
But it’s just scanning a do…
I SAID LOW ON INK!!
I just to install the drivers.”
I got at that thread because of [Archive.is] Troy Hunt on Twitter: “No? Yes? The UX in this @Epson printer is undoubtedly one of the worst I’ve ever seen. Just insane. (Near new ET-16600 FWIW.)… :
Title: Confirmation
Text: The wired LAN connection is disabled when using a Wi-Fi connection.

Yesterday, I wrote about Learn to program the gradual way: Welcome to Hedy! and today is the next installment: about numerals.
[Archive] /Fay-lee-nuh/ (@Felienne) | Twitter kind of by surprise discovered that the ten numerical digits of the decimal numeral system used in virtually all programming languages are not the original Arabic forms.
Supporting other forms of decimal numerals will help learning to program when your background is non-English or even using ten systems outside the Arabic numeral realm so common in Latin alphabets. And they are a fun learning exercise for every body too!
Some of the related Tweets on this:
Some more related Wikipedia links:
In the Unicode pages, look for “numeral”, “number”, and “numeric” (or just for “num”).

Cool way to learn programming in a gradual way which works adults just as well as for kids: [Wayback/Archive] Felienne/hedy
Hedy is a gradual programming language to teach children programming. Gradual languages use different language levels, where each level adds new concepts and syntactic complexity. At the end of the Hedy level sequence, kids master a subset of syntactically valid Python.

Via Jan Gentleman, I learned
Action 1: Try a Windows Key sequence to wake the screen.
If you’re using a device with a keyboard connected to it, select Windows logo key + Ctrl + Shift + B. If you’re in tablet mode, press the volume-up and volume-down buttons simultaneously three times within two seconds. If Windows is responsive, a short beep will sound and the screen will blink or dim while Windows attempts to refresh the screen.
Via:
WIN + CTRL + Shift + B: Tells the computer you’re experiencing a black screen and tries to fix it” / Twitter
Later I found out it also is in Table of keyboard shortcuts – Wikipedia: General shortcuts
Restart Video Driver Windows 10: Ctrl+⇧ Shift+⊞ Win+B[2][3]
Also I learned how people order the modifier keys is varying.
