  • Texas Linux Fest 2019 in Dallas

    A few years ago I started to suggest to TXLF staff that coming to Dallas was a good idea. I wanted there to be more tech conferences in Dallas, and I love the community organized nature of TXLF and similarly SCALE. Plus, it was Texas Linux Fest, it can't always be in Austin! This year I was able to convince them to take the risk and try a year in Dallas. It is a huge risk, as it is likely that many sponsors and regular attendees might not be interested in traveling up I-35 to attend. Being in Dallas also opens up huge opportunity to reach new audiences and new sponsors. Now to prove that.

  • Linux Fu: The Kitchen Sync

    One of the great things about Linux and similar operating systems is they are configurable. If you don’t like something, there’s a great chance you can change it easily with a few entries in a file somewhere. For example, take bash — a very popular shell by any measure. If you want a different style of command line editing, there’s an option. You want the tab key to match files regardless of case? Another option. Usually, these are set in one of your so-called profile files like .bashrc in your home directory.

    As long as you are sitting in front of your single computer working, this is great. You customize your .bashrc and other files to your heart’s content and then you work in an environment that acts the way you want it to. The problem is when you have a lot of computers. Maybe you have a web server, a desktop, a firewall machine, and a few dozen Raspberry Pi computers. How do you keep all the configurations the same? Then once they are the same, how do you keep them up to date?

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.

    The Vaumarcus miniDebConf19 is happening! Come see the fantastic view from the shores of Lake Neuchâtel, in Switzerland! We’re going to have two-and-a-half days of presentations and hacking in this marvelous venue and anybody interested in Debian development is welcome.

  • 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.

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
