Too many fail to grasp the relevance of sovereignty to the common person...
Sovereignty is not having to worry (too much) whether or not another country chooses to elect a dangerous idiot to govern it.
Lack of sovereignty is depending so much on another country that such a choice has real consequences for you, while not having any say (i.e. vote).

Take the Intel 8088... 16-bit registers, but with an 8-bit data bus and 20-bit address bus.
Was it an 8-bit CPU? Does anyone consider the original IBM PC an 8-bit machine?
And would that have been 16-bit if it had used an 8086 instead?
What about the Z80 and the 6502? Both had an 8-bit data bus and a 16-bit address bus, but only the Z80 had 16-bit registers.
At least we can agree that no system using either a Z80 or a 6502 ever called itself 16-bit, right? 🤔

In Portugal there's a dearth of technical community gatherings. It's a serious problem, and one that seems to be getting worse (if that's at all possible).
I'm not talking about corporate events that people attend on behalf of their employers. We have our share of those. I'm talking about events that people attend, on their own time, because they want to meet people with similar personal interests.
These people exist, but they just don't come together!

Nestas eleições perderam todos. Os dois maiores partidos acabam praticamente num empate, mas os votantes no terceiro maior partido são os que mais perdem, pois serão as primeiras vítimas das suas ideias.

They could have started by printing their flyers in toilet paper. This one is just too glossy for a good clean.

Não sou votante de nenhum dos dois, mas o Polígrafo devia ter vergonha deste título.
O Polígrafo propõe-se fazer algo positivo no contexto das notícias falsas mas é frequente contribuirem para o problema com títulos editorializados e escolhas questionáveis de "notícias" para analisar.

@npub1aw2…8vv5 My personal suggestion for LG TVs is to refuse every possible user agreement, including the voice recognition one that pops up every time you accidentally click the microphone button on the remote.
And above all, to disable "Live Plus" (inside "Additional Settings"), which can periodically upload screenshots of your screen and sound captures "to third-parties" for recommendation purposes.
Not sure it works around this parts, but yeah...

@npub1rdh…wzv5 O público não tem de saber nenhuma dessas coisas, a não ser que sejam ilegais ou incompatíveis com o exercício das funções, ou haja razões suficientes para suspeitar que o possam ser.
Qualquer cidadão tem direito à privacidade, mesmo que não tenha nada a esconder. Isto inclui os políticos, na medida do razoável.
Partir do pressuposto que todos os políticos são criminosos ou imorais já é um problema na nossa democracia.

@npub1rdh…wzv5 Isso seria profundamente prejudicial à qualidade da democracia.
Quem, com o mínimo de competência, quereria fazer política e ver a sua vida devassada pela comunicação social, quando pode ter uma vida mais descansada no setor privado?
Isto já acontece, em parte.
A comunicação social é demonstradamente incompetente para escrutinar seja o que for de uma forma objetiva, operar na presunção de inocência, ou fornecer à sociedade civil a informação adequada para o fazer ponderadamente.

RIP, Niklaus Wirth, 15 February 1934 – 1 January 2024. Probably best known for the Pascal programming language. 🪦
https://en.m.wikipedia.org/wiki/Niklaus_Wirth
Pascal was the first programming language I learned way back in 1995 with Turbo Pascal on my first PC, and the first language where I actually *learned* how to program in 1997, with GNU Pascal (ISO) at the university.
Pascal may not be Brian Kernighan's favorite language, but I owe it my career, sort of. 🙇‍♂️

Não tenho quaisquer problemas com o português do Brasil, mas os falantes de português de Portugal podem por favor parar de usar o verbo "compartilhar" nas redes sociais?
Se dizem "partilhar" quando falam, porque não o escrevem também?
Já agora... o acordo ortográfico de 1990 removeu as consoantes mudas, mas mantêm-se em "facto" e "contacto".
E, ao contrário do que os jornalistas vos possam fazer crer, sempre que se sentirem tentados a escrever "estória", é para escrever sempre "história".

When observed from the outside, #retrocomputing may appear driven by escapism from modern technology and nostalgia for simpler times – which isn't false, really, and there's nothing wrong with that – but that doesn't mean it's backward-looking.
There's so much new stuff being done in this area, from software-defined ISA cards to FPGA-based reimplementations of old chips and whole-system emulation.
And there's so much to learn from older, simpler, systems that can be applied to modern problems.

It's been one year since I created this account. I haven't posted on Xitter since August, I'm not on Bluesky, and I won't try Threads.
I'm not a #fediverse believer, but we know those other platforms will inevitably enshittify. I want no part in that.
#mastodon can feel a bit like shouting into the void, though. But that's OK, you shouldn't care if the stuff you write is read by many or by few.

@npub1aw2…8vv5 The FDIV bug was widely covered by computer magazines in late 1994. Linux checked for it (and the F00F bug, found a couple of years later) in early boot for years.
When I was shopping for my first PC in 1995 it was still a concern, as some affected chips might still be lurking in stocks. I remember asking at the shop about the stepping of the P100 I was buying.
I'm curious how "for one frame the game would show a completely different part of the map" from such a small rounding error.

@npub18hd…kf64 I'm just relieved that our future overlord/reaper will be Microsoft SkyNet.
Plenty of opportunities to take it down while it automatically restarts at the worst possible moment (for it) to install updates, and then slows to a crawl while all the crapware tries to start at the same time after boot.

@npub1aw2…8vv5 As long as it is an "online" or "line-interactive" UPS. If it's an offline/standby UPS then it does nothing for power glitches, it only kicks in when power goes out for more than a few milliseconds (an actual outage).

@npub18hd…kf64 Chrome is hot garbage because the web is hot garbage, to the point I’m still unsure if these changes in Chrome are for the worse or for the better compared to the current status. It’s 💩 in both cases.
Also, Edge is cancer and Safari is the new IE (the one that makes you implement workarounds for things that work in every other browser).
Firefox is OK, but Mozilla made a sequence of missteps over the years and now faces an uphill battle to win users back.

@npub18hd…kf64 @npub1m8w…puqs One can trust the FST not to use the copyright assignments to take a project closed source, but they can still use it to make unilateral licensing changes based on their own ideology.
They did it when the GPLv3 came out and, to me, it was a bad step.
The Linux kernel is the best example of why not being able to relicense the code is actually a good thing.

@npub18hd…kf64 Over the last decade or so, people's understanding of open source has drifted towards free software, where the code is built and owned by a community.
At the same time, the corporate expectation of open source has always centered around having a community contributing back.
Note the subtle difference.
This is true whenever a project is dominated by a single company. And even more so when it asks for copyright assignments from contributors.
This move is not surprising.

Users of RHEL clones aren't freeloaders, but that doesn't mean there aren't any freeloaders around.
Oracle, SUSE, and CIQ are recreating United Linux 21 years later, but now it isn't about creating a distro to compete with Red Hat, it's about ensuring they can keep selling support contracts on top of 1:1 RHEL clones.

This just makes @npub1hkw…jkge look like the torch bearer for the original CentOS "spirit" and the better choice if you prefer the Red Hat flavor of Linux.

Just finished reading "UNIX: A History and a Memoir" by Brian Kernighan — best known as the "K" in "AWK" and for co-authoring "The C Programming Language" book with Dennis Ritchie.
It's mostly about early Unix and its context within Bell Labs, which is what makes it interesting.
Lex Friedman interviewed Brian Kernighan in 2020. It's well worth a watch:

Also worth a watch is this zany Unix promotional video from 1982:
