Facebook Knew of Cambridge Analytica Data Misuse Earlier Than Reported

An anonymous reader quotes a report from The Guardian: Facebook employees were aware of concerns about "improper data-gathering practices" by Cambridge Analytica months before the Guardian first reported, in December 2015, that the political consultancy had obtained data on millions from an academic. The concerns appeared in a court filing by the attorney general for Washington DC and were subsequently confirmed by Facebook. The new information "could suggest that Facebook has consistently mislead [sic]" British lawmakers "about what it knew and when about Cambridge Analytica," tweeted Damian Collins, the chair of the House of Commons digital culture media and sport select committee (DCMS) in response to the court filing. In a statement, a company spokesperson said: "Facebook absolutely did not mislead anyone about this timeline." After publication of this article, the spokesperson acknowledged that Facebook employees heard rumors of data scraping by Cambridge Analytica in September 2015. The spokesperson said that this was a "different incident" from Cambridge Analytica's acquisition of a trove of data about as many as 87 million users that has been widely reported on for the past year. "In September 2015 employees heard speculation that Cambridge Analytica was scraping data, something that is unfortunately common for any internet service," the spokesperson said. "In December 2015, we first learned through media reports that Kogan sold data to Cambridge Analytica, and we took action. Those were two different things." The filing raised questions about when Facebook first learned about the misuse of personal data by Cambridge Analytica, the now defunct political consultancy.

Walmart Is Looking Into Launching Its Own Cloud Gaming Service, Report Says

Google's Stadio cloud-gaming service may be intercepted by a similar service from Walmart. According to a report from US Gamer, the American retail giant is looking into launching its own cloud gaming service. From the report: Multiple sources familiar with Walmart's plans, who wish to remain anonymous, confirmed to USG that the retail giant is exploring its own platform to enter in the now-competitive video game streaming race. No other details were revealed other than it will be a streaming service for video games, and that Walmart has been speaking with developers and publishers since earlier this year and throughout this year's Game Developers Conference. Walmart's discussions with developers for its streaming service have been secretive, and it's unclear how far along the service is in-development. But our sources are confident that this is a space Walmart is trying to move into. Though Walmart might sound like a strange company to be jumping into the streaming tech space, the move isn't wholly unexpected. In recent years due to competition from Amazon, Walmart has been increasingly looking into more tech-focused markets beyond its traditional physical retail chain. Over time, Walmart has integrated its physical stores with its large online presence, offering deliveries, app integrations, and in-store pick up services. Walmart also has a technology arm in Silicon Valley called Walmart Labs, which has 6,000 employees and develops tech for Walmart's digital presence. In addition it boasts tools like Cruxlux, which is a search engine designed to reveal the connection between any two people, places, or things. Finally, Walmart has a data center unofficially called Area 71 in Caverna, Missouri which holds over 460 trillion bytes of data. Data centers are a centerpiece of Google's Stadia streaming service and companies like Microsoft, Amazon, and Apple also own powerful data facilities, all of whom are also coincidentally working in streaming technology.

Crashed Boeing Planes Lacked Safety Features That Company Sold Only As Extras

The recent Boeing 737 MAX crashes involving an Ethiopian Airlines flight and a Lion Air flight may have been a result of two missing safety features that Boeing charged airlines extra for (Warning: source may be paywalled; alternative source). The New York Times reports that many low-cost carriers like Indonesia's Lion Air opted not to buy them so they could save money, even though some of these systems are fundamental to the plane's operations. "Now, in the wake of the two deadly crashes involving the same jet model, Boeing will make one of those safety features standard as part of a fix to get the planes in the air again," the report says. From the report: It is not yet known what caused the crashes of Ethiopian Airlines Flight 302 on March 10 and Lion Air Flight 610 five months earlier, both after erratic takeoffs. But investigators are looking at whether a new software system added to avoid stalls in Boeing's 737 Max series may have been partly to blame. Faulty data from sensors on the Lion Air plane may have caused the system, known as MCAS, to malfunction, authorities investigating that crash suspect. The jet's software system takes readings from one of two vanelike devices called angle of attack sensors that determine how much the plane's nose is pointing up or down relative to oncoming air. When MCAS detects that the plane is pointing up at a dangerous angle, it can automatically push down the nose of the plane in an effort to prevent the plane from stalling. Boeing's optional safety features, in part, could have helped the pilots detect any erroneous readings. One of the optional upgrades, the angle of attack indicator, displays the readings of the two sensors. The other, called a disagree light, is activated if those sensors are at odds with one another. The angle of attack indicator will remain an option that airlines can buy. Neither feature was mandated by the Federal Aviation Administration. All 737 Max jets have been grounded. "Boeing will soon update the MCAS software, and will also make the disagree light standard on all new 737 Max planes," the report adds, citing a person familiar with the changes. "Boeing started moving on the software fix and the equipment change before the crash in Ethiopia." Slashdot reader Futurepower(R) adds to the story: The FBI has joined the criminal investigation into the certification of the Boeing 737 MAX, lending its considerable resources to an inquiry already being conducted by U.S. Department of Transportation agents, according to people familiar with the matter. "The federal grand jury investigation, based in Washington, D.C., is looking into the certification process that approved the safety of the new Boeing plane, two of which have crashed since October.

Pulling strings

After one year of managing a network of 10 servers with Cfengine I'm currently building two clusters of 50 servers with Puppet (which I'm using for the first time), and have various notes to share. With my experience I had a feeling Cfengine just isn't right for this project, and didn't consider it seriously. These servers are all running Debian GNU/Linux and Puppet felt natural because of the good Debian integration, and the number of users whom also produced a lot of resources. Chef was out of the picture soon because of the scary architecture; CouchDB, Solr and RabbitMQ... coming from Cfengine this seemed like a bad joke. You probably need to hire a Ruby developer when it breaks. Puppet is somewhat better in this regard.

Puppet master needs Ruby, and has a built-in file server using WEBrick. My first disappointment with Puppet was WEBrick. Though PuppetLabs claim you can scale it up to 20 servers, that proved way off, the built-in server has problems serving as little as 5 agents/servers, and you get to see many dropped connections and failed catalog transfers. I was forced to switch to Mongrel and Nginx as frontend very early in the project, on both clusters. This method works much better (even though Apache+Passenger is the recommended method now from PuppetLabs), and it's not a huge complication compared to WEBrick (and Cfengine which doesn't make you jump through any hoops). Part of the reason for this failure is my pull interval, which is 5 minutes with a random sleep time of up to 3 minutes to avoid harmonics (which is still a high occurrence with these intervals and WEBrick fails miserably). In production a customer can not wait on 30/45 minute pull intervals to get his IP address whitelisted for a service, or some other mundane task, it must happen within 10 minutes... but I'll come to these kind of unrealistic ideas a little later.

Unlike the Cfengine article I have no bootstrapping notes, and no code/modules to share. By default the fresh started puppet agent will look for a host called "puppet" and pull in what ever you defined to bootstrap servers in your manifests. As for modules, I wrote a ton of code and though I'd like to share it, my employer owns it. But unlike Cfengine v3 there's a lot of resources out there for Puppet which can teach you everything you need to know, so I don't feel obligated to even ask.

Interesting enough, published modules would not help you get your job done. You will have to write your own, and your team members will have to learn how to use your modules, which also means writing a lot of documentation. Maybe my biggest disappointment is getting disillusioned by most Puppet advocates and DevOps prophets. I found articles and modules most of them write, and experiences they share have nothing to do with the real world. It's like they host servers in a magical land where everything is done in one way and all servers are identical. Hosting big websites and their apps is a much, much different affair.

Every customer does things differently, and I had to write custom modules for each of them. Just between these two clusters a module managing Apache is different, and you can abstract your code a lot but you reach a point where you simply can't push it any more. Or if you can, you create a mess that is unusable by your team members, and I'm trying to make their jobs better not make them miserable. One customer uses an Isilon NAS, the other has a content distribution network, one uses Nginx as a frontend, other has chrooted web servers, one writes logs to a NFS, other to a Syslog cluster... Now imagine this on a scale with 2,000 customers and 3 times the servers and most of the published infrastructure design guidelines become laughable. Instead you find your self implementing custom solutions, and inventing your own rules, best that you can...

I'm ultimately here to tell you that the projects are in a better state then they would be with the usual cluster management policy. My best moment was an e-mail from a team member saying "I read the code, I now understand it [Puppet]. This is fucking awesome!". I knew at that moment I managed to build something good (or good enough), despite the shortcomings I found, and with nothing more than using PuppetLabs resources. Actually, that is not completely honest. Because I did buy and read the book Pro Puppet which contains an excellent chapter on using Git for collaboration on modules between sysadmins and developers, with proper implementation of development, testing and production (Puppet)environments.
