Following the rioting and looting from the death of George Floyd, Apple has a message for those who power on a stolen iPhone: "This device has been disabled and is being tracked. Local authorities will be alerted." Forbes reports: Apple CEO Tim Cook sent a message to his employees as those protests escalated, saying that "there is a pain deeply etched in the soul of our nation and in the hearts of millions. To stand together, we must stand up for one another, and recognize the fear, hurt, and outrage rightly provoked by the senseless killing of George Floyd and a much longer history of racism." Cook went on to say that "at Apple, our mission has and always will be to create technology that empowers people to change the world for the better. We've always drawn strength from our diversity, welcomed people from every walk of life to our stores around the world, and strived to build an Apple that is inclusive of everyone." These words were being digested as the tech giant made the decision to close the majority of its U.S. stores for the safety of those staff and its customers, stores that had only just reopened after the COVID-19 shutdown. Apple has unsurprisingly become a favored target of looters, given the likely spoils on offer, and the decision was taken to remove stock from shop floors and shutter locations. It has long been known that Apple operates some form of proximity software that disables a device when it is taken illegally from a store. Until now, though, little had been seen of that technology in action. Well, thanks to social media, we can now see the message that greets a looter powering up their new device: "This device has been disabled and is being tracked," it says. "Local authorities will be alerted."

Google was sued on Tuesday in a proposed class action accusing the internet search company of illegally invading the privacy of millions of users by pervasively tracking their internet use through browsers set in "private" mode. Reuters reports: The lawsuit seeks at least $5 billion, accusing the Alphabet unit of collecting information about what people view online and where they do their browsing, despite using what Google calls Incognito mode. The complaint said Google surreptitiously collects data through Google Analytics, Google Ad Manager and other applications and website plug-ins, including smartphone apps, regardless of whether users click on Google-supported ads. This helps the Mountain View, California-based company learn details about users' friends, hobbies, favorite foods, shopping habits, and even the "most intimate and potentially embarrassing things" they search for online, the complaint said. Google "cannot continue to engage in the covert and unauthorized data collection from virtually every American with a computer or phone," the complaint said. The complaint said the proposed class likely includes "millions" of Google users who since June 1, 2016 browsed the internet in "private" mode. It seeks damages per user of $5,000 or three times actual damages, whichever is greater, for violations of federal wiretapping and California privacy laws.

MojoKid writes: AI and Machine Learning performance benchmarks have been well explored in the data center, but are fairly new and unestablished for edge devices like smartphones. While AI implementations on phones are typically limited to inferencing tasks like speech-to-text transcription and camera image optimization, there are real-world neural network models employed on mobile devices and accelerated by their dedicated processing engines. A deep dive look at HotHardware of three popular AI benchmarking apps for Android shows that not all platforms are created equal, but also that performance results can vary wildly, depending on the app used for benchmarking. Generally speaking, it all hinges on what neural networks (NNs) the benchmarks are testing and what precision is being tested and weighted. Most mobile apps that currently employ some level of AI make use of INT8 (quantized). While INT8 offers less precision than FP16 (Floating Point), it's also more power-efficient and offers enough precision for most consumer applications. Typically, Qualcomm Snapdragon 865 powered devices offer the best INT8 performance, while Huawei's Kirin 990 in the P40 Pro 5G offers superior FP16 performance. Since INT8 precision for NN processing is more common in today's mobile apps, it could be said that Qualcomm has the upper hand, but the landscape in this area is ever-evolving to be sure.

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.
