  • KDE 5_15.04 for Slackware-current: back to work

    An update to my KDE 5 packages was overdue. Ever since the “big upgrade” in Slackware-current a week ago on 21 April 2015, there have been some stability issues in the Plasma 5 desktop. The instability was caused by the version bumps of various libraries that the KDE software is depending on – you can not dynamically link to a software library that’s no longer there because it has been replaced with a library bearing a new version number. I felt I had to recompile everything just to be sure there was no hidden “breakage” left, and so I took the opportunity to wait for the newest Plasna release and present you wilth all-new packages.

What's what in Debian Jessie

Filed under
Debian

Debian is arguably the most important Linux distribution. From it springs such popular Linux distributions as Mint and Ubuntu. Outside Linux's inner circles, it's not that well known because it's purely a community operating system. There is no company behind it, as there is with Red Hat and CentOS, Fedora, and Red Hat Enterprise Linux (RHEL). Without fanfare, Debian is more than just the foundation for other better known Linux distros, it is a powerful desktop and server Linux in its own right.

Taking Ubuntu’s Monkey for a Ride

Filed under
Reviews
Ubuntu

That seems to be the response from desktop users and reviewers of Ubuntu’s latest and greatest, 15.04 or Vivid Vervet. The server and cloud crowd are all abuzz, tearing this baby down to see what it can do. But for the desktop folks — not so much. About all you read is that the new desktop is mainly cosmetic changes: that Unity’s color scheme is now purple, which isn’t quite true — to my eyes, there’s some orange in there too — and that a few things have been moved back to where they used to be. Other than that, everyone complains that this vervet is nothing more than lipstick on a unicorn, as Utopic Unicorn was Ubuntu’s last release.

What this means, of course, is absolutely nothing. The folks at Ubuntu have made it clear that this is mostly a server/cloud release, so it’s not surprising that it offers desktop users little reason to upgrade. Besides, except for those few users who insist on living on the bleeding edge, most desktop users should be using 14.04, Trusty Tahr, anyway, because it’ll be supported until 2019, and our vervet friend will only see support through January.

Ubuntu Ditches Upstart

Filed under
Ubuntu

Ubuntu is not the first distro to use systemd. Debian (Ubuntu's daddy) recently made the switch too. Other distros have experienced bugs as a result of the switch. For instance, service managers, which configure the boot config files, must be changed to work with the new init system.

Ubuntu cleverly sidestepped this problem by keeping its old init config file formats in place alongside the new format used by systemd. The version of systemd used in Ubuntu can read both. So old tools that work with the Upstart config settings still work.

systemd does provide a boost in boot performance over Upstart, but some members of the community are concerned that the way systemd handles messages to services will reduce performance and even open the door to denial-of-service attacks.

Clearly, Canonical must have a lot of faith in systemd to abandon Upstart (its own project) in its favor. As time passes, we will see whether this was a wise decision.

The Companies That Support Linux: Fox Technologies

Filed under
Linux

Linux has long been regarded as a stable and secure platform for enterprise applications. And the recent explosion of container technology presents yet another way for developers to build securely on top of Linux, says Mark Lambiase, CTO of Fox Technologies, Inc.

The Linux container model “will provide for the opportunity to separate and segment applications from a shared OS model, which can provide both security and performance/configuration advantages,” Lambiase said.

Fox Technologies, which helps companies manage and maintain Unix and Linux systems with its BoKS ServerControl application, is contributing to such growth and innovation in the Linux ecosystem, in part, by becoming new corporate members of the Linux Foundation. (See the full announcement.)

The bottom line, according to TI is that the 66AK2L06 can do almost everything FPGAs can do in data acquisition, but can do it in a way that is cheaper, faster, and more power efficient. The SoC is also claimed to be easier to work with than using FPGAs.

Open Hardware: Raspberry Pi and Arduino

  • Introducing the Raspberry Pi Pico Microcontroller - IoT Tech Trends

    The Raspberry Pi Foundation comes through again with another innovative device. Already well-known for its series of single-board computers, the company has announced the Raspberry Pi Pico, a microcontroller that costs a shockingly low $4. Adding to the interest, the company is using its own RP2040 chip for it, meaning it’s making its own silicon, just like Apple with its M1.

  • Kernel 5.10.9 compiled for Pi4

    EasyOS for the Raspberry Pi4, version 2.6, has the 5.10.4 Linux kernel. I have now compiled the 5.10.9 kernel, that will be used in the next release of Easy.

  • Fixed compile of Samba without krb5 in OE

    EasyOS on the Pi4 does not have samba, as compile failed in OE. Yes, I could compile it in a running EasyOS on the Pi4, but would rather fix it in OE. I have a 'samba_%.bbappend' file, the main objective being to remove the 'pam' and 'krb5' dependencies. I worked on this recipe this morning. The problem is that instead of 'krb5', the internal 'heimdahl' is used, and this compiles two binaries, that are then executed during compile. The problem is that the binaries are compiled for the target system, in this case aarch64, whereas the build system is x86_64, so the binaries cannot run. OE does have a mechanism to handle this. It is possible to compile 'samba-native', that is, samba compiled to run on the build-system, and then use the two binaries from that when compile 'samba'. Fine, except that exactly how to do this is very poorly documented. The official documentation is very vague. A couple of years ago, I bought a book, "Embedded Linux Systems with the Yocto Project", but found that it also said hardly anything about this. I consider this to be an important topic, yet it seems that many OE experts don't know much about it either.

  • Arduino Blog » Turn your staircase into a flaircase with this LED system

    If you live in a house with stairs and have to traipse up and down at night, it’s best to have some sort of light that guides you. Although a cell phone can work just fine, or you could likely activate bright overhead lighting, creator MagicManu devised an automatic and progressive solution to illuminate his path instead. MagicManu’s system knows when someone is there using PIR sensors arranged at both ends, and only activates if it’s dark enough thanks to a photoresistor. The entire setup is controlled by an Arduino Nano, while two potentiometers adjust light sensitivity and duration of ignition.

Red Hat’s Disruption of CentOS Unleashes Storm of Dissent

Five weeks after angering much of the CentOS Linux developer community by unveiling controversial changes to the no-cost CentOS operating system, Red Hat has unveiled alternatives for affected users that give them several options for using existing Red Hat products. But for many users of CentOS Linux, the Red Hat options won’t solve the huge problems that were created for them when Red Hat announced Dec. 8 that CentOS would no longer include a stable version with a long, steady future. Instead, CentOS will now only be offered as a free CentOS Stream operating system which will be a rolling release with frequent updates, essentially turning it into a beta OS that is no longer suitable for reliable production workloads. For users who have deployed CentOS throughout the internet, data centers, corporate and business uses and more, this is a potentially major blow. Read more Also: Fedora program update: 2021-03

The Demise of Chromium as Free Software

  • This is why Leading Linux Distros going to remove Chromium from their Official Repositories

    Jochen Eisinger from Google team mentioned in a discussion thread that they will be banning sync support system of Chromium. This lead to lot of frustration in the Linux Dev community & rage against googles sudden decision. This Decision can kill small browser projects & lead the web to single browser monopoly i.e. Google Chrome! As a result of the googles decision multiple distros are strictly considering removal of Chromium from their official repositories. Leading distros like Arch Linux, Fedora, Debian, Slackware & OpenSUSE have stated that if the sync support goes down from google they will definitely remove chromium from their official repositories.

  • Chromium 88 removes Flash support [Ed: But DRM added]

    I uploaded a set of chromium packages to my repository today. Chromium 88.0.4324.96 sources were released two days ago. The release notes on the Google Chrome Releases Blog mention 36 security fixes with at least one being tagged as “critical” but the article does not mention that Flash support has been entirely removed from Chromium now. Adobe’s Flash was already actively being blocked for a long time and you had to consciously enable Flash content on web pages, but after Adobe discontinued Flash on 1st of January 2021 it was only a matter of time before support in web browsers would be removed as well. Let’s also briefly revisit the topic of my previous post – Google will remove access to Chrome Sync for all community builds of the open source variant of their Chrome browser: Chromium… thereby crippling it as far as I am concerned.

  • Chrome 89 Preparing To Ship With AV1 Encoder For WebRTC Usage [Ed: Massive patent trap]

    Now that Chrome 88 released, attention is turning to Chrome 89 of which an interesting technical change is the enabling of AV1 encode support within the web browser. Going back to 2018 there's been AV1 decode support within the browser when wanting to enjoy content encoded in this royalty-free, modern codec. But now for Chrome 89 is coming AV1 encode support. AV1 encode support is being added for the WebRTC use-case for real-time conferencing. Web applications like WebEx, Meet, and Duo (among others) already support using AV1 for better compression efficiency, improved low-bandwidth handling, and greater screen sharing efficiency. While hardware-based AV1 encoding isn't yet common, Chrome Linux/macOS/Windows desktop builds are adding the ability to use CPU-based AV1 encoding.

José Antonio Rey: New times, new solutions

Just as humans change, the Ubuntu community is also changing. People interact in different ways. Platforms that did not exist before are now available, and the community changes as the humans in it change as well. When we started the Local Communities project several years ago, we did it with the sole purpose of celebrating Ubuntu. The ways in which we celebrated included release parties, conferences, and gatherings in IRC. However, we have lately seen a decline in the momentum we had with regards to participation in this project. We have not done a review of the project since its inception, and inevitably, the Community Council believes that it is time to do a deep dive at how we can regain that momentum and continue getting together to celebrate Ubuntu. As such, we are putting together the Local Communities Research Committee, an independent entity overseen by the Community Council, which will help us understand the behavior of Local Community teams, how to better adapt to their needs, and to create a model that is suitable for the world we are living in today.
