  • Four Apollo Lake Pico-ITX SBCs start at $245 in single units

    Logic Supply has launched four Ubuntu-ready “EPM16x” Pico-ITX SBCs with Apollo Lake SoCs starting at $245. The $426 and up EPM163 has a Pentium N4200, 4GB LPDDR4, 64GB eMMC, mSATA, mini-PCIe, and 2x each of GbE, DP, and USB 3.0.

    We’ve reported on over a dozen Linux-friendly Pico-ITX boards with Intel Apollo Lake processors over the last few years, including most recently, Axiomtek’s PICO319 and IEI’s Hyper-AL. Yet, as some of our readers have complained, they are rarely announced with ship dates or prices, and if they are, they usually list only volume pricing.

  • Huawei Covers Android Gap with IoT OS

    If you’ve been watching the smartphone world, you may know of Huawei’s problems with the United States. Huawei has had a spotty history of spying on American technology, to the point where Huawei products have been banned from being sold in the US.

    Huawei responded by saying they would very much like to continue relations with Android and have been hoping they get a second chance with the technology giant. They have stated, however, that if they are officially cut off from Android, they would make their own OS.

  • A guided tour of Linux file system types

    While it may not be obvious to the casual user, Linux file systems have evolved significantly over the last decade or so to make them more resistant to corruption and performance problems.

    Most Linux systems today use a file system type called ext4. The “ext” part stands for “extended” and the 4 indicates that this is the 4th generation of this file system type. Features added over time include the ability to provide increasingly larger file systems (currently as large as 1,000,000 TiB) and much larger files (up to 16 TiB), more resistance to system crashes and less fragmentation (scattering single files as chunks in multiple locations) which improves performance.

    If you are installing Tails into a VM for testing or anything else, always remember to mark the drive as a removable USB drive. Otherwise, the installation step will finish properly, but, you will get errors like the following screenshot while booting from the drive.

Debian: Introducing Noir, miniDebConf19 Vaumarcus and New FAI.me Feature

  • Introducing Noir

    Noir is a drop-in replacement for Black (the uncompromising code formatter), with the default line length set to PEP-8's preferred 79 characters. If you want to use it, just replace black with noir in your requirements.txt and/or setup.py and you're good to go. Black is a Python code formatter that reformats your code to make it more PEP-8 compliant. It implements a subset of PEP-8, most notably it deliberately ignores PEP-8's suggestion for a line length of 79 characters and defaults to a length of 88. I find the decision and the reasoning behind that somewhat arbitrary. PEP-8 is a good standard and there's a lot of value in having a style guide that is generally accepted and has a lot of tooling to support it. When people ask to change Black's default line length to 79, the issue is usually closed with a reference to the reasoning in the README. But Black's developers are at least aware of this controversial decision, as Black's only option that allows to configure the (otherwise uncompromising) code formatter, is in fact the line length. Apart from that, Black is a good formatter that's gaining more and more popularity. And, of course, the developers have every right to follow their own taste. However, since Black is licensed under the terms of the MIT license, I tried to see what needs to be done in order to fix the line length issue.

  • New FAI.me feature

    FAI.me, the build service for installation and cloud images has a new feature. When building an installation images, you can enable automatic reboot or shutdown at the end of the installation in the advanced options. This was implemented due to request by users, that are using the service for their VM instances or computers without any keyboard connected.

FreeBSD's Executive Director Calls For Linux + BSD Devs To Work Together

While called the Open-Source Summit, the event is primarily about Linux as after all it's hosted by the Linux Foundation. But at this week's Open-Source Summit in San Diego, Deb Goodkin as the executive director of the FreeBSD Foundation presented. Deb's talk was of course on FreeBSD but also why FreeBSD and Linux developers should work together. The presentation covered FreeBSD's development workflow and various features of this open-source operating system project for those unfamiliar as well as some of the companies utilizing FreeBSD and their different use-cases. It's a good overview for those not familiar with FreeBSD. Read more

LG Has Been Working On Reduced Boot Times With Hibernation Optimizations

LG Electronics has been exploring improvements around hibernation/suspend-to-disk to speed-up the Linux boot process for consumer electronics rather than performing cold boots and as part of that is working towards upstream optimizations. While hibernation-based booting is generally quicker than performing cold boots, suspending to disk does yield extra writes to the NAND flash memory on these consumer devices and that is one of the things they are seeking to avoid. So it's been an effort not only to speed-up the hibernation boot process but also reducing the amount of data that needs to be written out to the flash storage. Read more
