Ubuntu-Centric Full Circle Magazine and Debian on the Raspberryscape

  • Full Circle Magazine: Full Circle Weekly News #121
  • Debian on the Raspberryscape: Great news!
    I already mentioned here having adopted and updated the Raspberry Pi 3 Debian Buster Unofficial Preview image generation project. As you might know, the hardware differences between the three families are quite deep ? The original Raspberry Pi (models A and B), as well as the Zero and Zero W, are ARMv6 (which, in Debian-speak, belong to the armel architecture, a.k.a. EABI / Embedded ABI). Raspberry Pi 2 is an ARMv7 (so, we call it armhf or ARM hard-float, as it does support floating point instructions). Finally, the Raspberry Pi 3 is an ARMv8-A (in Debian it corresponds to the ARM64 architecture). [...] As for the little guy, the Zero that sits atop them, I only have to upload a new version of raspberry3-firmware built also for armel. I will add to it the needed devicetree files. I have to check with the release-team members if it would be possible to rename the package to simply raspberry-firmware (as it's no longer v3-specific). Why is this relevant? Well, the Raspberry Pi is by far the most popular ARM machine ever. It is a board people love playing with. It is the base for many, many, many projects. And now, finally, it can run with straight Debian! And, of course, if you don't trust me providing clean images, you can prepare them by yourself, trusting the same distribution you have come to trust and love over the years.

OSS: SVT-AV1, LibreOffice, FSF and Software Freedom Conservancy

  • SVT-AV1 Already Seeing Nice Performance Improvements Since Open-Sourcing
    It was just a few weeks ago that Intel open-sourced the SVT-AV1 project as a CPU-based AV1 video encoder. In the short time since publishing it, there's already been some significant performance improvements.  Since the start of the month, SVT-AV1 has added multi-threaded CDEF search, more AVX optimizations, and other improvements to this fast evolving AV1 encoder. With having updated the test profile against the latest state as of today, here's a quick look at the performance of this Intel open-source AV1 video encoder.

  • What I learned during my internship with the FSF tech team
    Hello everyone, I am Hrishikesh, and this is my follow-up blog post concluding my experiences and the work I did during my 3.5 month remote internship with the FSF. During my internship, I worked with the tech team to research and propose replacements for their network monitoring infrastructure. A few things did not go quite as planned, but a lot of good things that I did not plan happened along the way. For example, I planned to work on GNU LibreJS, but never could find enough time for it. On the other hand, I gained a lot of system administration experience by reading IRC conversations, and by working on my project. I even got to have a brief conversation with RMS! My mentors, Ian, Andrew, and Ruben, were extremely helpful and understanding throughout my internship. As someone who previously had not worked with a team, I learned a lot about teamwork. Aside from IRC, we interacted weekly in a conference call via phone, and used the FSF's Etherpad instance for live collaborative editing, to take notes. The first two months were mostly spent studying the FSF's existing Nagios- and Munin-based monitoring and alert system, to understand how it works. The tech team provided two VMs for experimenting with Prometheus and Nagios, which I used throughout the internship. During this time, I also spent a lot of time reading about licenses, and other posts about free software published by the FSF.

Security: Back Doors Running Amok, Container Runtime Flaw Patched, Cisco Ships Exploit Inside Products

  • Here We Go Again: 127 Million Accounts Stolen From 8 More Websites
    Several days ago, a hacker put 617 million accounts from 16 different websites for sale on the dark web. Now, the same hacker is offering 127 million more records from another eight websites.
  • Hacker who stole 620 million records strikes again, stealing 127 million more
    A hacker who stole close to 620 million user records from 16 websites has stolen another 127 million records from eight more websites, TechCrunch has learned. The hacker, whose listing was the previously disclosed data for about $20,000 in bitcoin on a dark web marketplace, stole the data last year from several major sites — some that had already been disclosed, like more than 151 million records from MyFitnessPal and 25 million records from Animoto. But several other hacked sites on the marketplace listing didn’t know or hadn’t disclosed yet — such as 500px and Coffee Meets Bagel. The Register, which first reported the story, said the data included names, email addresses and scrambled passwords, and in some cases other login and account data — though no financial data was included.
