  • Pinebook Pro Unboxed, Booted, Then Taken Apart [Video]

    The second batch of Pinebook Pro pre-orders went live this week, just as buyers of the first wave begun to receive their devices!

    And, naturally, as you’d expect, in true millennial tech ownership style, a swathe of Pinebook Pro unboxing videos started to sprout out of the web’s fertile mantle.

    Including the following comprehensive run-through by YouTuber jpakkane1 (a link to which landed in the omg! tip box yesterday, so thanks Sadat!).

    This 10 minute clip has everything you could possibly want to see: a literal unboxing; first boot experience; side-by-side comparison with (unfair klaxon sound) a 13.1″ MacBook (!); and connection to an external display.

OSMC's October update is now here. We didn't release an update in August or September as we waited to collate a significant number of improvements and stabilise Kodi 18.4 for our users. We are working on a number of significant improvements that will take some more time, but wanted to delay this update no further and maintain our commitment to regular updates.

We continue our development for 3D Frame Packed (MVC) output for Vero 4K / 4K + and a significantly improved video stack which will land before the end of the year.

Our work on preparing Raspberry Pi 4 support continues.

Team Kodi recently announced the 18.4 point release of Kodi Leia. We have now prepared this for all supported OSMC devices and added some improvements and fixes.

Disney+ streaming uses draconian DRM, avoid

Web

First of all, as always my opinions are my own, not those of my employer.

Since I have 2 children I was happy to learn that the Netherlands would be one of the first countries to get Disney+ streaming.

So I subscribed for the testing period, problem all devices in my home run Fedora. I started up Firefox and was greeted with an "Error Code 83", next I tried Chrome, same thing.

So I mailed the Disney helpdesk about this, explaining how Linux works fine with Netflix, AmazonPrime video and even the web-app from my local cable provider. They promised to get back to me in 24 hours, the eventually got back to me in about a week. They wrote: "We are familiar with Error 83. This often happens if you want to play Disney + via the web browser or certain devices. Our IT department working hard to solve this. In the meantime, I want to advise you to watch Disney + via the app on a phone or tablet. If this error code still occurs in a few days, you can check the help center ..." this was on September 23th.

  • Google Has Been Developing "libgav1" As New AV1 Decoder

    While there exists DAV1D as one of the most promising AV1 decoders to date, Google has been developing libgav1 as its own AV1 decoder and focused on Arm-powered Android devices but also x86_64 desktop CPUs as well.

    Google made its first libgav1 code drop on Friday for this AV1 decoder focused on AV1 profile 0 and profile 1 content. GAV1 is focused on decoding IVF files and so far features the likes of Arm NEON and x86 SSE4.1 CPU optimizations.

  • DAV1D vs. LIBGAV1 Performance - Benchmarking Google's New AV1 Video Decoder

    With the surprise code drop of Google developing a new open-source AV1 video decoder as "libgav1", I set out this Saturday to run benchmarks on various systems for seeing how the performance is looking for this CPU-based decoder in relation to the more well known DAV1D decoder.

    Libgav1 is now available alongside the many other video encoders/decoders for benchmarking via the Phoronix Test Suite with OpenBenchmarking.org. I fired up a number of different Linux systems so far in seeing how the performance compares with a wide array of AMD and Intel processors.

Programming: Mutter & GNOME Shell Hackfest, PyCon Africa 2019 (Recap) and More Python

  • Real Python: PyCon Africa 2019 (Recap)

    PyCon Africa was a wonderful, inspiring, and technically enlightening conference that took place in Accra, Ghana from August 6 to 10, 2019 at the University of Ghana. This conference was the very first pan-African conference for Python developers and was attended by 323 Pythonistas from 26 different countries. Most of the attendees traveled from countries around Africa, and a number of speakers came from the US, the Netherlands, Germany, Brazil, and Italy. Python is becoming more and more adopted all across the globe. In Africa, Python is earning a special place for itself, where it’s used extensively for web development and data science. African businesses are looking for developers with Python skills in these areas, and having a PyCon in Africa provides a foundation to help support African programmers. [...] The day after the main conference was dedicated to sprints! This is where people group up to work on various open source Python projects. I was part of a team that worked on Cookie Cutter and other related projects. I submitted a PR that got merged into the project and I also helped mentor other team members. I highly recommend anyone who has not attended a sprint before to do so! It’s a great way to practice your skills, contribute to an open source project, and meet the developers involved with the project.

  • Tutorial: How to Read Stata Files in Python with Pandas

    We are soon going to practically answer how to open a Stata file in Python? In Python, there are two useful packages called Pyreadstat, and Pandas that enable us to open .dta files. If we are working with Pandas, the read_stata method will help us import a .dta into a Pandas dataframe. Furthermore, the package Pyreadstat, which is dependent on Pandas, will also create a Pandas dataframe from a .dta file.

  • Python Software Foundation: Seeking Developers for Paid Contract Improving pip

    The Python Software Foundation Packaging Working Group is receiving funding to work on the design, implementation, and rollout of pip's next-generation dependency resolver. (We'll be able to publicly name the funders later this month and in early December.) pip is the official package installer for Python. pip aims to make it easy for the millions of people who use Python to download and install Python libraries and applications (open source and closed source, source and binary, globally and within isolated virtual environments). It's a foundational component of the Python ecosystem and broader computer software and technology landscape. This project aims to complete the design, implementation, and rollout of pip's next-generation dependency resolver. This will lower the barriers to installing Python software, empowering users to get a version of a package that works. It will also lower the barriers to distributing Python software, empowering developers to make their work available in an easily reusable form. Because of the size of the project, funding has been allocated to secure two contractors, a senior developer and an intermediate developer, to work on development, testing and building test infrastructure, code review, bug triage, and assisting in the rollout of necessary features.

Database of 200+ smartphones that can run Linux (unofficially)

The vast majority of smartphones in the world ship with some version of Google’s Android operating system. And most of them are only supported by their manufacturers for a few years. Have a phone that’s 3-4 years old? Then you’re probably not getting any Android updates anymore. No more security patches. No new features. Of course, some folks can run custom ROMs such as LineageOS, which lets you install updates indefinitely… but want to break out of Android altogether? There are a handful of other GNU/Linux-based operating systems including Ubuntu Touch, postmarketOS, and Maemo Leste that are designed to, among other things, help give your phone a longer lifespan. One tricky thing can be figuring out which phones are supported. That’s where a new Can My Phone Run Linux database from TuxPhones comes in. Read more

Linux driver patches indicate AMD is readying integer scaling

Both Intel and Nvidia have released graphics driver updates to enable integer scaling options this year. Intel made a big song and dance out of the development process with Tweets and blog updates trailing the graphics driver feature. Then integer scaling became available for Intel Gen11 graphics users after a September driver update. Nvidia actually pipped Intel to the post by implementing integer scaling (for Turing GPUs) in its Gamescom driver release in August - it snuck in the update without much fanfare as it simultaneously boosted a number of AAA games performance and added some new image sharpening features.

  • Entry Server Bang For The Buck, IBM i Versus Red Hat Linux

    In last week’s issue, we did a competitive analysis of the entry, single-socket Power S914 machines running IBM i against Dell PowerEdge servers using various Intel Xeon processors as well as an AMD Epyc chip running a Windows Server and SQL Server stack from Microsoft. This week, and particularly in the wake of IBM’s recent acquisition of Red Hat, we are looking at how entry IBM i platforms rate in terms of cost and performance against X86 machines running a Linux stack and an appropriate open source relational database that has enterprise support. Just as a recap from last week’s story, the IBM i matchup against Windows Server systems were encouraging in that very small configurations of the Power Systems machine running IBM i were less expensive per unit of online transaction processing performance as well as per user. However, on slightly larger configurations of single socket machines, thanks mostly to the very high cost per core of the IBM i operating system and its integrated middleware and database as you move from the P05 to P10 software tiers on the Power S914, the capital outlay can get very large at list price for the Power iron, and the software gets very pricey, too. The only thing that keeps the IBM i platform in the running is the substantially higher performance per core that the Power9 chip offers on machines with four, six, or eight cores. Such processors are fairly modest by 2019 standards, by the way, when a high-end chip has 24, 28, 32, or now 64 cores, and even mainstream ones have 12, 16, or 18 cores. If you want to see the rationale of the hardware configurations that we ginned up for the comparisons, we suggest that you review the story from last week. Suffice it to say, we tried to get machines with roughly the same core counts and configuration across the Power and X86 machines, and generally, the X86 cores for these classes of single socket servers do a lot less work.
