“La vague crypto a touché la Suède et cela inquiète fort les instances du pays. Depuis que la Chine a mis un coup d’arrêt au minage de cryptomonnaies sur son sol, la géographie du secteur a été complètement redessinée. Des pays comme les États-Unis et le Kazakhstan ont attiré nombre de sociétés crypto contraintes de délocaliser à la hâte leurs sites de minage. Mais la Suède, qui a pour elle une belle production d’énergie renouvelable, a également tapé dans l’œil des mineurs de crypto.”

Deep in rural China, bitcoin miners are packing up

“To evade the clampdown, big miners have sent their machines overseas. Mr Su, who also runs a logistics business that transports mining machines, has been chartering Boeing 747s to get used ones out swiftly. Most are going to Russia and Kazakhstan, which together account for about 13% of the world’s bitcoin mining. But there are few data centres abroad with space for lots of new machines, including in America, the second-biggest miner. Building a farm there costs between five and ten times what it does in China, says Mr Su. That is too much for most Chinese miners. More than half of their computers will stay put for now, he says.”

“We’ve enhanced Android’s auto-rotate feature with face detection, using the front-facing camera to more accurately recognize when to rotate the screen. This is especially helpful for people who are using their devices while lying down on a couch or in bed, for example. For developers, this means that the auto-rotation behavior will provide a better user experience for users who have opted in through Settings. The enhanced auto-rotate feature lives within our recently announced Private Compute Core, so images are never stored or sent off the device. In Beta 3 this feature is available on Pixel 4 and later Pixel devices.To make screen rotation as speedy as possible on all devices, we’ve also optimized the animation and redrawing and added an ML-driven gesture-detection algorithm. As a result, the latency for the base auto-rotate feature has been reduced by 25%, and the benefits of the face detection enhancement build on top of those improvements. Give the auto-rotate improvements a try and let us know what yo”

A Colonial Pipeline facility in Baltimore. Its pipelines feed large storage tanks up and down the East Coast.

« We are apolitical, we do not participate in geopolitics, do not need to tie us with a defined government and look for our motives, » it said in a statement posted on its website. « Our goal is to make money and not creating problems for society. »
The group seemed somewhat surprised that its actions resulted in closing a major pipeline and suggested that perhaps it would avoid such targets in the future.

Un édito contre le « merci » envoyé par courrier électronique

“Combien de tonnes équivalent carbone pourrait-on économiser ? 16 433 – soit 280 000 km en voiture, ou 40 000 aller-retour Londres-Madrid en avion… En renonçant juste un fois par jour, une seule fois, à envoyer ce fameux petit « merci », vous imaginez ?”

Vraiment ? Il est temps de prendre ce sujet au sérieux et d’arrêter de dire des…

“The latest announcements place Amazon at the distant back of the pack. In 2019, the company revealed a then-ambitious plan to achieve net-zero carbon emissions by 2040, and to use 100% renewable electricity by 2030. But the company’s vast logistics network is a significant hurdle not faced by its competitors: the company has purchased 100,000 electric delivery vehicles, but deploying them to the road will not be complete by 2030.”

“L’objectif : créer, en deux semaines, un Web alternatif qui puisse tenir sur une clé USB d’1 giga. Il raconte : « On a tout déconstruit, et listé ce à quoi ils tenaient dans le Web : à Wikipédia, à la communication, aux mèmes… Chacun se répartit une des fonctions du web et ils recréent leurs services à eux. Les étudiants aiment YouTube, pas pour YouTube en lui-même mais pour la connaissance qu’ils y trouvent. Cela pose aussi des questions de gouvernance : puisqu’on ne peut pas tout faire tenir sur 1 Go, faut-il faire sortir un service pour en laisser entrer un autre ? Déterminer une durée de vie pour un site ? ». Les étudiants vont fabriquer leur propre serveur avec un Rasberry Pi, et l’alimenter avec un panneau solaire. « Comme ça, la nuit, notre web n’est plus accessible et il revient le lendemain matin (c’est aussi le cas du site du Low-Tech Magazine, ndlr). On va s’amuser avec des contraintes. »”

“To put that in context, researchers at Nvidia, the company that makes the specialised GPU processors now used in most machine-learning systems, came up with a massive natural-language model that was 24 times bigger than its predecessor and yet was only 34% better at its learning task. But here’s the really interesting bit. Training the final model took 512 V100 GPUs running continuously for 9.2 days. “Given the power requirements per card,” wrote one expert, “a back of the envelope estimate put the amount of energy used to train this model at over 3x the yearly energy consumption of the average American.” You don’t have to be Einstein to realise that machine learning can’t continue on its present path, especially given the industry’s frenetic assurances that tech giants are heading for an “AI everywhere” future.”

“The internet is the wider network that allows computer networks around the world run by companies, governments, universities and other organisations to talk to one another. The result is a mass of cables, computers, data centres, routers, servers, repeaters, satellites and wifi towers that allows digital information to travel around the world. It is that infrastructure that lets you order the weekly shop, share your life on Facebook, stream Outcast on Netflix, email your aunt in Wollongong and search the web for the world’s tiniest cat.”
