@Kasparov63 Too negative towards EU. Austerity is the true reason behind EU lacking. Look at Covid-19, as soon as the pursue opened Europe produced not one, but two Covid vaccines in record time

@katrinat Mér skilst reyndar að Fram hafi aldrei skrifað undir afsalið af Safamýri þó svo að Víkingur væri fluttur inn út af einhverjum slag við Reykjavíkurborg varðandi uppbyggingu. Það hefur allt verið í hnút út af þessu skilst mér og þetta er væntanlega lausnin?

@owenjonesjourno I'm all for more equality but I think you are wrong. Media consumption has changed, now the battlefield is in channels like TikTok, Facebook, and X. There extreme right messeging is winning, and not just in the USA i might add.

This, above all else, is what matters.
The US economic model is bust. Wages for most working people have stagnated for decades.
Either you offer an answer to that, or someone else will.
But the best Kamala Harris could muster was "I'm not Trump". That didn't work.

Roughly *67%* of voters rated the economy as "not so good/poor," per Washington Post exit polls A shockingly poor number amid a hot labor market, booming stocks, much lower inflation, growing GDP But widespread voter dissatisfaction w/ the economy been clear for years

What happens if your CPU gets something wrong? If it wakes up one day and decides 2+2=5?
Well, most of us will never have to worry about that. But if you work at a company the size of Google, you do, which is why this paper on "mercurial cores" is so fascinating.
What the authors report--and supposedly this is common knowledge at the hyperscalers--is that a couple cores per several thousand machines are "mercurial." Due to subtle manufacturing defects or old age, they give wrong answers for certain instructions. These can cause all sorts of impossible-to-diagnose issues. Some rare problems at Google that were traced back to bad CPUs include:
- Mutexes not working, causing application crashes
- Silent data corruption
- Garbage collectors targeting live memory, causing application crashes
- Kernel state corruption causing kernel panics
What makes CPUs go bad? It's very hard to tell. The authors posit that issues are becoming more frequent as CPUs get more complex, but there aren't solid numbers behind that. There are certainly strong relationships between frequency, temperature, voltage, and bad CPU behavior--most mercurial CPUs only cause problems under very specific conditions, but those conditions vary from CPU to CPU. Age is another source of problems, as older CPUs are more likely to exhibit problems.
Bad CPUs are an especially serious problem because they're very hard to detect. If cosmic rays flip bits in storage or on the network, that can be detected through error coding. But there's no analogy for a CPU that allows cheap online verification of its correctness. Instead, the best detection techniques involve monitoring for symptoms. If a core exhibits exceptionally high rates of process crashes or kernel panics relative to its fellows, that's a strong indication something is wrong with it. For the most critical applications, the authors propose triple modular redundancy--redoing each of its computations on three cores and majority-voting a reliable result.
More than anything, this paper is a call to action--letting everyone know that CPUs can fail. So now, if you ever find a bug you can't diagnose, you can blame the CPU! 🙂

@WilliamFristad @azubarrend @gilroy0 @jimbo_madison @OttoWerkr @SethBarronNYC @jordanzakarin @tiffanyhopeful @AOC Yep, civilizations rise and fall, and so does Sunday's off apparently. I wonder if there's a bronze age equivalent?

@ernire @azubarrend @gilroy0 @jimbo_madison @OttoWerkr @SethBarronNYC @jordanzakarin @tiffanyhopeful @AOC We're both right, Charlemagne enforced it by issuing "Capitularies" and thus mandating rest on Sundays. I recall he sought to unify Christian practices in the empire by doing so.

@WilliamFristad @azubarrend @gilroy0 @jimbo_madison @OttoWerkr @SethBarronNYC @jordanzakarin @tiffanyhopeful @AOC "Karl der große", also known as "Charlemagne", the holy Roman emporer ~800 AD was responsible for Sundays off work. It was mostly to strengthen the church at the time.

@BjornIvarBjorns @arnarar Þetta eru laun, þú sérð að mótframlag er yfir 10 milljónir sem stemmir við laun upp á 75 milljónir. Þetta eru þrír starfsmenn með rétt yfir 2 milljónir á mánuði (ef jafnt er)

@arnarar Fellur það ekki undir verktakagreiðslur og þar með launakostnað þegar þú kaupir vinnu? T.d. kaup á skýrslum. Trúi ekki að þrír starfsmenn séu með þessi laun. En hvað veit maður svosem.

Talandi um elítu. Ríkissjóður á yfir 99,99% í Betri samgöngum. Starfsmannakostnaður við 3 ársverk er hátt í 100 milljónir á mann.
Samgöngustyrkur er 50 þúsund á mann á mánuði. Töluvert meira en kort í Strætó.
Framkvæmdastjórinn er besti vinur Sjálfstæðisflokksins.

Það er alltaf alvöru real talk þegar @StefnStefnsson6 talar og ég missi því aldrei af þætti þar sem hann kemur fram. Í Spursmálum í gær náði hann út úr æðstapresti Betri samgangna að þar séu almenningssamgöngur sjaldan notaðar. Almenningssamgöngur eru fyrir aðra, ekki elítuna.

Ha ha ha I remember this review. It’s epic! 😂
Those of us who remember the Da Vinci Code when it came out (book and movie) remember how stupid it was. It’s like a Chetan Bhagat novel on steroids (in terms of writing “quality”).
