Faille sur les #processeurs Intel : quelles protections, quelles conséquences possibles #numerama https://www.numerama.com/tech/318251-faille-critique-sur-les-processeurs-intel-quelles-seront-les-consequences.html #intel

Je me souviens avoir acheté (il y a longtemps) un Pentium 90Mhz qui souffrait d'un bug qui touchait les opérations sur nombres à virgules flottantes (de mémoire). A l'époque l'affaire avait fait grand bruit, même si Internet n'existait pas ou peu, et #Intel avait mis en place un programme d'échange de CPU => j'avais reçu un CPU tout neuf par la poste.
J'ai l'impression que les temps ont changé ...

#intel has been selling #defective CPUs for over a decade, and yet they will be allowed to continue to exist without facing an investigation or financial penalties?

That's some all-American bullshit right there.

A fundamental design flaw in #Intel’s processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level #security bug. […]
Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we’re looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model.

Alors j'admet, je ne comprends pas comment on peut faire un patch dans le kernel si le processeur a une faille de sécurité non patchable 😕 #Intel
Il ne faut pas remplacer le processeur, du coup ? Ou alors le « non patchable », ça s'applique juste aux versions suivantes du processeur, mais c'est patchable en modifiant le kernel ?

"How it works" > link to youtube vid.

Uh, what happened to websites using text to explain how they work.

I guess they want to appeal to emotions instead of stating the facts.

...because emotions and human body language influence how we interpret words.

maybe BTC will prompt the development of widespread geothermal or nuclear energy, and a race for fusion power.

or it’ll just use too much electricity and crashes.

I made a flow chart of which Mastodon posts end up in which timelines!

So, you can see how each instance will have a different local timeline, and even a slightly different federated timeline - and you can see why the federated timeline moves so much faster than the local one, too.

EU 'will be forever seen as hypocrites’ after ‘pathetic’ response to #Catalonia violence.

The EU has it's roots in trade agreements. The interest of protecting human rights came later, and as it seems still standing in secound line.

“Of course it's a duty for any government to uphold the rule of law, and this sometimes does require the proportionate use of force'
