A few days ago, there was a #ReproducibleBuilds issue on #LTSP that was pointed out to me by @lamby who also proposed a fix...
But, I wanted to write something worth pushing upstream, and had some hours on the train to kill...
I luckily had recently debugged the issue just a couple days before, so my package cache had all the necessary .deb files already:
sbuild ... --no-apt-update
And I was able to build, despite lacking network!
But post-build hooks could not install packages...

Episode 25 of our technology podcast @RuntimeArguments (http://RuntimeArguments.fm) and yes, I’m insanely late with this post, though the episode was on time. This episode is called "The X Window System and Wayland".
Jim @jammcq digs into the connection between Linux programs and windows showing up on the screen in front of you. Wolf @YesJustWolf asks all the dumb questions you wouldn’t have uttered even if you were in the room (mostly because Wolf doesn’t care about looking dumb).
As always, we want to know what you think:

Outra coisa que eu estava pesquisando na madrugada: sistemas #diskless. Explico: com a profusão de pequenos computadores chineses, vários deles baseados em processadores Ryzen de bom desempenho, fiquei pensando no seguinte:
"Para fins de otimização tributária e maximização de utilidade, não faz mais sentido importar o sistema sem RAM e disco? Vários fabricantes oferecem a opção e assim é mais fácil configurar do jeito que eu quero..."
Na sequência, pensei que faria sentido importar sem RAM e sem disco e colocar apenas RAM. Com a economia, é possível ter mais RAM, mas isso exige boot pela rede. Eis que comecei a pesquisa.
Depois de me deparar com uma documentação desatualizada desde 2017 no #Debian, acabei descobrindo que o #LTSP segue vivo. Desde 2019, o projeto foi reorientado. Os clientes não podem ser leves agora, pois há todo um "encantamento" baseado em squashfs, o qual demanda mais RAM, porém, o desempenho tende a ser melhor e o servidor não precisa servir desktops inteiros pela rede (algo que, graças à ineficiência atual de toolkits, Wayland, etc, é pesado, já que virou streaming de vídeo).
Para clientes modestos, ainda existem outras opções, com ou sem LTSP envolvido.
I wish I could ever find this page on the WWW again (archive more than likely?).
I used to be fan/nerd about #LTSP / #K12LTSP from 2001-05 and I remember clearly one build log/write up from some nerdy Linux school admin at the time. (Now known as #K12Linux)
They built with these specs that I can recall:
-TYAN mobo w/support for and installed dual AMD Opterons (single core)
-pretty sure they used horrendous Thermaltake Xaser case (or some chieftec/Antec SX clone).
-I forgot the HDD/RAM config
Thin client was a great technology here, it meant old donated computers could be refurbished well because they didn't need the mechanical parts that failed first on computers.
You just needed one powerful machine to drive them all.
To make the #LTSP setup a little easier, we would use drive mirroring to set up servers for each school.
The first year or so, I just did things that way, making improvements here and there.

LTSP helps in netbooting LAN clients from a single template installation that resides in a virtual machine image or a chroot on the LTSP server, or the server root (/, chrootless). This way maintaining tens or hundreds of diskless clients is as easy as maintaining a single PC.
Just finished to setup a pxe boot server using the fantastic Linux Terminal Server Project. After following the docs I ended up with a DHCP and tftp server in half an hour.
