A catastrophe at Twitch – by Casey Newton – Platformer

7 octobre 2021 /

“’We’re currently investigating the issue and will have more to share as we have additional detail,’ the company told me. But according to the former engineers I spoke with, Twitch had a notoriously lax approach to internal security that, in the view of some, made an incident like today’s more likely. Among the issues they identified:

  • The company did not develop an effective model to counter internal threats — that is, employees who might seek to steal data or cause other problems.
  • Every engineer could clone every code repository, making it possible for someone to essentially copy and paste the entire code base.
  • Despite being owned by Amazon since 2014, Twitch still has its own information security practices, which are generally weaker.

‘No other company has this level of facepalm,’ one engineer told me.”

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

7 octobre 2021 /

“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.”

Digital Addictions Are Drowning Us in Dopamine

7 octobre 2021 /

“Our brains evolved this fine-tuned balance over millions of years in which pleasures were scarce and dangers ever-present. The problem today is that we no longer live in that world. Instead, we now live in a world of overwhelming abundance. The quantity, variety and potency of highly reinforcing drugs and behaviors has never been greater. In addition to addictive substances like sugar and opioids, there is also a whole new class of electronic addictions that didn’t exist until about 20 years ago: texting, tweeting, surfing the web, online shopping and gambling.”

An Inconvenient Truth About AI

7 octobre 2021 /

A chart of Milestones in AI from 1950 to 2020.

“Regardless of what you might think about AI, the reality is that just about every successful deployment has either one of two expedients: It has a person somewhere in the loop, or the cost of failure, should the system blunder, is very low. In 2002, iRobot, a company that I cofounded, introduced the first mass-market autonomous home-cleaning robot, the Roomba, at a price that severely constricted how much AI we could endow it with. The limited AI wasn’t a problem, though. Our worst failure scenarios had the Roomba missing a patch of floor and failing to pick up a dustball.”

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.”

Whistle-Blower Says Facebook ‘Chooses Profits Over Safety’

4 octobre 2021 /

Frances Haugen, the Facebook whistle-blower, revealed her identity on Sunday and gave an interview to “60 Minutes.”

“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.””

Deep in rural China, bitcoin miners are packing up

1 octobre 2021 /

“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.”

Ces Afghans qui effacent leurs traces numériques par crainte des talibans

1 octobre 2021 /

Des talibans contrôlent des conducteurs dans le centre de Kaboul, en Afghanistan, le 15 septembre 2021.

“Lorsque Kaboul est tombée aux mains des talibans, le 15 août, Nilofar Ayoubi a créé, avec ses amies militantes des droits humains, un groupe WhatsApp sur lequel elles échangeaient les dernières informations. « C’est sur ce groupe que j’ai découvert le dispositif mis en place par Facebook pour les Afghans. Je l’ai donc utilisé pour verrouiller mon compte Facebook. J’ai aussi changé la photo et le nom de mes comptes Instagram et Twitter, tout en les rendant privés », explique cette entrepreneuse afghane. Figure de l’opposition aux talibans, cette mère de trois enfants vit aujourd’hui en exil en Pologne.”

YouTube Bans Anti-Vaccine Misinformation

1 octobre 2021 /

YouTube said it was banning the accounts of several prominent anti-vaccine activists from its platform, including Robert F. Kennedy Jr.’s.

“In a blog post, YouTube said it would remove videos claiming that vaccines do not reduce rates of transmission or contraction of disease, and content that includes misinformation on the makeup of the vaccines. Claims that approved vaccines cause autism, cancer or infertility, or that the vaccines contain trackers, will also be removed.
Prominent anti-vaccine activists have long been able to build huge audiences online, helped along by the algorithmic powers of social networks that prioritize videos and posts that are particularly successful at capturing people’s attention. A nonprofit, the Center for Countering Digital Hate, published research this year showing that a group of 12 people were responsible for sharing 65 percent of all anti-vaccine messaging on social media, calling the group the “Disinformation Dozen.” In July, the White House cited the research as it criticized tech companies for allowing misinformation about the coronavirus and vaccines to spread widely, sparking a tense back-and-forth between the administration and Facebook.”
