Indice de réparabilité – Le consommateur bien mal éclairé – UFC-Que Choisir

Indice de réparabilité

“Cet indice, calculé par les constructeurs, repose sur une grille standardisée articulée autour de 5 critères (documentation, facilité de démontage, disponibilité des pièces détachées, leur prix et un critère spécifique à la famille de produit). Chaque critère pèse curieusement le même poids dans la note finale, au détriment de critères déterminants tels que la disponibilité des pièces détachées. Cette construction aboutit à des absurdités. Par exemple, alors que les smartphones et les téléviseurs obtiennent une note inférieure à la moyenne sur le critère de disponibilité des pièces détachées, respectivement 4,8/10 et 3,1/10, ces familles affichent des indices de réparabilité élogieux de 7,2/10 et 6,6/10”

Faille Log4shell : les attaques ransomware démarrent déjà

https://c1.lestechnophiles.com/www.numerama.com/wp-content/uploads/2020/05/hacker-5-1024x577.jpg

« Les craintes se concrétisent. De premières attaques ransomwares qui exploitent la faille Log4shell ont été observées par l’entreprise de sécurité informatique Bitdefender, et ce dès le week-end qui a suivi sa découverte le 10 décembre 2021. Cette vulnérabilité 0-day permet d’exécuter du code à distance sans authentification et d’accéder aux serveurs concernés.

Il s’agit d’une faille rêvée pour des opérateurs de ransomware vu la facilité d’entrée dans les systèmes vulnérables qu’elle fournit. La liste de logiciels concernés par la vulnérabilité est astronomique, et beaucoup de grands groupes étaient exposés : Amazon, Tesla, Apple, Steam, Minecraft ou même des services de Google ».

Qualcomm’s new always-on smartphone camera is a potential privacy nightmare

“’Your phone’s front camera is always securely looking for your face, even if you don’t touch it or raise to wake it.’ That’s how Qualcomm Technologies vice president of product management Judd Heape introduced the company’s new always-on camera capabilities in the Snapdragon 8 Gen 1 processor set to arrive in top-shelf Android phones early next year.
Depending on who you are, that statement can either be exciting or terrifying. For Qualcomm, it thinks this new feature will enable new use cases, like being able to wake and unlock your phone without having to pick it up or have it instantly lock when it no longer sees your face.
But for those of us with any sense of how modern technology is used to violate our privacy, a camera on our phone that’s always capturing images even when we’re not using it sounds like the stuff of nightmares and has a cost to our privacy that far outweighs any potential convenience benefits.”

Facebook AI moderator confused videos of mass shootings and car washes | Ars Technica

A frowning man in a business suit.

“Facebook’s internal documents reveal just how far its AI moderation tools are from identifying what human moderators were easily catching. Cockfights, for example, were mistakenly flagged by the AI as a car crash. “These are clearly cockfighting videos,” the report said. In another instance, videos livestreamed by perpetrators of mass shootings were labeled by AI tools as paintball games or a trip through a carwash. If the situation sounds grim in the US or among English-speaking countries, it appears far worse elsewhere. In Afghanistan, for example, the company said in reports that it lacks a dictionary of slurs in the country’s various languages. As a result, Facebook estimates that it identified just 0.23 percent of hate speech posted on the platform in Afghanistan.”

Squid Game Cryptocurrency Scammers Make Off With $2.1 Million

The price of SQUID cryptocurrency plunging to $

“If you’re going to buy cryptocurrency, the most important thing to look out for isn’t necessarily the price. First, figure out whether you can sell the coin after you bought it. If you can’t sell—like the people who invested in SQUID discovered they can’t—it doesn’t matter how high the price goes, just as it doesn’t matter how large of a number someone writes on Monopoly bills. Cryptocurrency is only worth what someone else is willing to pay for it. And if the rules say you can’t even sell, you’ve just been scammed. Sorry, folks.”

The Metaverse Was Lame Even Before Facebook, By Ethan Zuckerman

An image of a person wearing VR headset in 1995

“Neal Stephenson’s metaverse has been a lasting creation because it’s fictional. It doesn’t have to solve all the intricate problems of content moderation and extremism and interpersonal interaction to raise questions about what virtual worlds can give us and what our real world lacks. Today’s metaverse creators are missing the point, just like I missed the point back at Ted’s Fish Fry in 1994. The metaverse isn’t about building perfect virtual escape hatches—it’s about holding a mirror to our own broken, shared world. Facebook’s promised metaverse is about distracting us from the world it’s helped break.”

« Tuer gentiment sa femme, c’est bien » : les biais racistes et sexistes de Ask Delphi rappellent les limites de l’IA

“Pour essayer d’affiner son esprit critique, Delphi a donc passé de longs moments à scruter le web, et notamment les questions posées sur les pages Reddit r/AmITheAsshole (que l’on traduirait par « suis-je un trou du cul ? ») et r/Confessions, ou les redditeurs se livrent leurs secrets les moins avouables. Ces situations ont ensuite été soumises aux jugements de sous-traitants, employés grâce à l’Amazon Mechanical Turk, l’outil de microtâche à bas prix mis à disposition par Amazon. De ce processus est sorti une sorte de « guide moral » appelé Commonsense Norm Bank. Cette base de données « compile 1,7 million d’exemples de jugements éthiques de personnes, sur un large éventail de situations quotidiennes. »”

The Facebook Files

Facebook knows, in acute detail, that its platforms are riddled with flaws that cause harm, often in ways only the company fully understands. That is the central finding of a Wall Street Journal series, based on a review of internal Facebook documents, including research reports, online employee discussions and drafts of presentations to senior management.
Time and again, the documents show, Facebook’s researchers have identified the platform’s ill effects. Time and again, despite congressional hearings, its own pledges and numerous media exposés, the company didn’t fix them. The documents offer perhaps the clearest picture thus far of how broadly Facebook’s problems are known inside the company, up to the chief executive himself.

Fuite de Twitch : seulement 3 femmes sur les 100 streameurs les mieux payés au monde

“Les trois seules femmes qui figurent dans le top 100 des plus gros revenus de Twitch, entre septembre 2019 et octobre 2021, sont : Pokimane, à la 34e place, une streameuse de jeux vidéo, Amouranth, à la 48e place, qui fait des séances d’ASMR et des stream jacuzzi, et Sintica, à la 71e place, une DJ dont les lives sont focalisés sur la musique.
Pour quiconque suit de près ou de loin l’actualité de Twitch, cette nouvelle ne sera pas très étonnante : le sexisme et les commentaires misogynes sont très courants sur Twitch. Le harcèlement est également un fléau qui touche quasiment toutes les femmes streameuses, et le phénomène est encore plus exacerbé lors qu’elles sont spécialisées dans les jeux vidéo.”

More details about the October 4 outage – Facebook Engineering

More details about the Oct. 4 Facebook outage

“One of the jobs performed by our smaller facilities is to respond to DNS queries. DNS is the address book of the internet, enabling the simple web names we type into browsers to be translated into specific server IP addresses. Those translation queries are answered by our authoritative name servers that occupy well known IP addresses themselves, which in turn are advertised to the rest of the internet via another protocol called the border gateway protocol (BGP).
To ensure reliable operation, our DNS servers disable those BGP advertisements if they themselves can not speak to our data centers, since this is an indication of an unhealthy network connection. In the recent outage the entire backbone was removed from operation, making these locations declare themselves unhealthy and withdraw those BGP advertisements. The end result was that our DNS servers became unreachable even though they were still operational. This made it impossible for the rest of the internet to find our servers.
All of this happened very fast. And as our engineers worked to figure out what was happening and why, they faced two large obstacles: first, it was not possible to access our data centers through our normal means because their networks were down, and second, the total loss of DNS broke many of the internal tools we’d normally use to investigate and resolve outages like this.”
