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

7 octobre 2021 / noflux

“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

7 octobre 2021 / noflux

“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.”

Whistle-Blower Says Facebook ‘Chooses Profits Over Safety’

4 octobre 2021 / noflux

“While “Facebook has publicized its work to combat misinformation and violent extremism relating to the 2020 election and insurrection,” Ms. Haugen’s documents told a different story, one cover letter read. “In reality, Facebook knew its algorithms and platforms promoted this type of harmful content, and it failed to deploy internally recommended or lasting countermeasures.””

“A member of the Stanford Behavioral Laboratory posted on a Prolific forum, “We have noticed a huge leap in the number of participants on the platform in the US Pool, from 40k to 80k. Which is great, however, now a lot of our studies have a gender skew where maybe 85% of participants are women. Plus the age has been averaging around 21.” Wayne State psychologist Hannah Schechter seems to have been the first person to crack the case. “This may be far-fetched,” she tweeted, linking to Frank’s video, “but given the timing, virality of the video, and the user’s follower demographics….” Long-standing Prolific survey-takers complained on Reddit that Frank had made it difficult to find paid surveys to take on the overrun platform.”

N.Y.P.D. Robot Dog’s Run Is Cut Short After Fierce Backlash

“The AI Incident Database is a collection of harms or near harms realized in the real world by the deployment of intelligent systems. You are invited to submit reports to the database, whereupon accepted incidents will be indexed and made discoverable to people developing and deploying the next generation of AI technology to the world. Artificial intelligence will only be a benefit to people and society if we collectively record and learn from its failings.”

Exploiting vulnerabilities in Cellebrite UFED and Physical Analyzer from an app’s perspective

FFmpeg vulnerabiltiies by year

“Given the number of opportunities present, we found that it’s possible to execute arbitrary code on a Cellebrite machine simply by including a specially formatted but otherwise innocuous file in any app on a device that is subsequently plugged into Cellebrite and scanned. There are virtually no limits on the code that can be executed. For example, by including a specially formatted but otherwise innocuous file in an app on a device that is then scanned by Cellebrite, it’s possible to execute code that modifies not just the Cellebrite report being created in that scan, but also all previous and future generated Cellebrite reports from all previously scanned devices and all future scanned devices in any arbitrary way (inserting or removing text, email, photos, contacts, files, or any other data), with no detectable timestamp changes or checksum failures. This could even be done at random, and would seriously call the data integrity of Cellebrite’s reports into question.”

Why predictions are a lot like Pringles

“A forecast about what will happen in Syria, China or Japan is a simple way to convey a fleeting sense of understanding. The forecast will probably be wrong. But at the instant it is consumed, it gratifies. As I say, a lot like Pringles.”

“Sadly, despite the team’s groundbreaking technical achievements over the last 9 years — doing many things previously thought impossible, like precisely navigating balloons in the stratosphere, creating a mesh network in the sky, or developing balloons that can withstand the harsh conditions of the stratosphere for more than a year — the road to commercial viability has proven much longer and riskier than hoped. So we’ve made the difficult decision to close down Loon. In the coming months, we’ll begin winding down operations and it will no longer be an Other Bet within Alphabet.”
