  • Mir 0.32 Is Inching Close To Release With Many Improvements

    Canonical's developers working on the Mir display server are putting the finishing touches on the Mir 0.32 release.

    Mir 0.32 is another big release as the developers remain focus on getting their Wayland support squared away. Additionally, Mir developers have been working on Logind support that is needed so Mir shells like the EGMDE example shell or Unity 8 can be easily accessed from the GDM3 log-in/display manager.

  • [Older] CentOS vs Ubuntu

    Ubuntu and CentOS are both major players in enterprise environments and in the datacenter. There's no denying that both distributions have proven themselves in the server space, but with closer examination, these are two very different animals.

    Ubuntu is an excellent all-around contender. CentOS is purpose built for the enterprise in every aspect of its design.

  • HP Chromebook X2 Looks to Be First Detachable Chromebook to Support Linux Apps

    Support for running Linux apps is becoming a thing among Chromebook fans, and it looks like each day new Chrome OS devices are getting Linux app support.

    During the Google I/O annual developer conference last month, Google announced it is working to bring support for Linux apps in future versions of its Linux-based Chrome OS operating system for Chromebooks, and the first Chromebook to receive support for running Linux applications is, of course, Google's Pixelbook.

  • Windows 10 alternatives: best free, open source operating systems

     

    Switching to an open source OS could involve a learning curve, but the community, customisation and lack of cost should be enough to make up for it.  

  • Laptops with 128GB of RAM are here

  • IMAP Spam Begone (ISBG) version 2.1.0 is out!

    When I first started at the non-profit where I work, one of the problems people had was rampant spam on their email boxes. The email addresses we use are pretty old (+10 years) and over time they have been added to all the possible spam lists there are.

    That would not be a real problem if our email hosting company did not have very bad spam filters. They are a worker's coop and charge us next to nothing for hosting our emails, but sadly they lack the resources to run a real bayesian-based spam filtering solution like SpamAssassin. "Luckily" for us, it seems that a lot of ISPs and email hosting enterprises also tend to have pretty bad spam filtering on the email boxes they provide and there were a few programs out there to fix this.

  • Be a redshirt this GUADEC

    If you’re planning to volunteer at GUADEC this year and be part of the selfless redshirt team (we’ve got 100% survival rate so far!), please register before the end of this week so that we have a better idea of which t-shirt sizes to order. If you can’t register soon, you can still volunteer even if you register on site!

  • GStreamer CI support for embedded devices

    GStreamer is a popular open-source pipeline-based multimedia framework that has been in development since 2001. That’s 17 years of constant development, triaging, bug fixes, feature additions, packaging, and testing. Adopting a Jenkins-based Continuous Integration (CI) setup in August 2013, GStreamer and its dependencies are now built multiple times a day with each commit. Prior to that, the multimedia project used a build bot hosted by Collabora and Fluendo. At the time of this writing, GStreamer is built for the Linux (Fedora & Debian), macOS, Windows, Android, and iOS platforms. A very popular deployment target for GStreamer are embedded devices, but they are not targeted in the current CI setup.This meant additional manpower, effort, and testing outside of the automated tests for every release of GStreamer to validate on embedded boards. To rectify this, a goal was devised to integrate embedded devices into the CI.

  • openSUSE Releases Leap 15 Images for Raspberry Pi, Armv7 Devices

    Makers can leverage openSUSE Leap 15 images for aarch64 and Armv7 on Internet of Things (IoT) and embedded devices. Since openSUSE Leap 15 shares a common core SUSE Linux Enterprise (SLE) 15 sources, makers who find success with a project or device can more comfortably transition to an enterprise product in the future should certifications become a requirement. Currently, the only IoT platform supported by SLE is the Raspberry Pi 3. However, there is no current supported migration from Leap 15 to SLE 15 with the Raspberry Pi. The barrier to entry in the IoT/embedded markets are lowered when a developer starts a project with Leap 15. Plus, the many supported arm boards can help developers circumnavigate future obstacles that might hinder project’s growth in a developing market.

  • SBo DMCA Takedown

    About 14h ago, 10:32 PM GMT+7 (Western Indonesian Time), me (and several other people who forked SBo's repository at GitHub) received a DMCA Takedown notice due to a company (Steinberg) filed a complaint to more than 200 open source repositories in GitHub that uses several of their header files (namely aeffect.h and aeffectx.h). We used that files in one of our scripts (jack-tools) which was changed over a year ago by the maintainer. At that time, it was OK to use their header files (although it has been unmaintained since 2013), but some time ago, Steinberg has made an announcement about dropping their support for VST 2 and focusing on VST 3 only. This drives the DMCA takedown action which affects SBo repositories in GitHub.

    The admins have discussed this matter last night and we came to a solution of fixing this issue permanently by removing the related commit and all the history for this script in master and 14.2 branch. This is not a trivial action as the commits involved were 11867 since 2017-02-04. Ponce did the initial testing and David did the final touch, including pushing an unexpected public update including with the mass re-base on master and 14.2 branch (Thanks David).

  • Mesa 18.1.1 is Now Available to Install on Ubuntu 18.04 LTS

    The latest Mesa 18.1.1 graphics stack is now available to install on Ubuntu 18.04 LTS.

    Mesa 18.1.1 is the first point release update in the Mesa 18.1.x series, which debuted back in May with Mesa 18.1.0.

    The Mesa 18.1.x series touts plenty of improvements, including better Vulkan and OpenGL performance, updated Tegra, Nouveau, and Intel drivers, as well as support for the OpenGL 4.5 API.

  • Active Searching [Ed: This good Ubuntu man could use a job. Consider hiring?]

    I generally am not trying to shoot for terse blog posts. That being said, my position at work is getting increasingly untenable since we're in a position of being physically unable to accomplish our mission goals prior to funding running out at 11:59:59 PM Eastern Time on September 30th. Conflicting imperatives were set and frankly we're starting to hit the point that neither are getting accomplished regardless of how many warm bodies we're throwing at the problem. It isn't good either when my co-workers who have any military experience are sounding out KBR, Academi, and Perspecta.

  • Astounding t-shirt art, created by marker-wielding open source hardware plotters

    Evil Mad Scientist Labs sell a bunch of cool open source hardware kits for making plotters -- basically, a very precise robot arm that draws with whatever pen or marker you screw into its grip. There's the Eggbot (for drawing on curved surfaces like eggs, balloons and balls), but there's also the Axidraw, which works on flat surfaces.

    Axidraw owners have been decorating tees with Axidraws and colored markers, creating some really smashing designs.

  • DeUHD Beats ‘New’ AACS 2.1 UHD Blu-ray Disc Protection

    Russian company Arusoft has released a new version of its DeUHD ripping tool which bypasses AACS 2.1. The new encryption version appeared last month on the UHD Blu-ray discs of Fury and The Patriot and couldn't be bypassed with existing tools. The new version makes it possible for pirates to rip the discs in question, which happened soon after.

  • CVE-2018-3665: Lazy State Save/Restore As The Latest CPU Speculative Execution Issue

    The latest speculative execution vulnerability affecting modern CPUs has now been made public: Lazy State Save/Restore, a.k.a. CVE-2018-3665.

    This vulnerability concerns saving/restore state when switching between applications. The newly-disclosed vulnerability exploits lazy-state restores for floating-point state when context switching, which is done as a performance optimization, to obtain information about the activity of other applications on the system.

  • AI Is Coming to Edge Computing Devices

    Very few non-server systems run software that could be called machine learning (ML) and artificial intelligence (AI). Yet, server-class “AI on the Edge” applications are coming to embedded devices, and Arm intends to fight with Intel and AMD over every last one of them.

  • On the Importance of On-Screen Keyboards

    The role of keyboards cannot be overstated. They originated long before computers, and survive in the smartphone era. Millions of people text their friend by tapping away on their shiny pocket computers using the venerable QWERTY layout dating back to 1873.

    It is hard to imagine a phone without a way to enter text. Some of us are dreaming about Minority Report-style gesturing, but the Librem 5 continues the keyboard tradition.

    [...]

    The task took me on an interesting and educating journey. The Wayland train took me via input methods to Asia, through protocols, to FLOSS communities. I will try to describe my story for you.

  • How Does Project Aiur, An Open Source AI-Engine Substantiate Scientific Knowledge

    As research in science progresses by leaps and bounds, there are a lot of readily available information in the online space, making knowledge sharing in areas like science easier.

    However, there is so much research information available that it is sometimes confusing as to what is right and what is wrong. Given the vast amount of resources, it is essential to carry out in-depth analysis of the resources. This has been made possible with AI and ML innovations.

  • OpenBSD at BSDCan 2018
  • Summer of Code: Evaluation and Key Lengths

    I spent some time testing my OpenPGP library PGPainless and during testing I noticed, that messages encrypted and signed using keys from the family of elliptic curve cryptography were substantially smaller than messages encrypted with common RSA keys. I knew already, that one benefit of elliptic curve cryptography is, that the keys can be much smaller while providing the same security as RSA keys. But what was new to me is, that this also applies to the length of the resulting message. I did some testing and came to interesting results:

  • Major speedup for big DWG's

    Thanks to David Bender and James Michael DuPont for convincing me that we need a hash table for really big DWGs. I got a DWG example with 42MB, which needed 2m to process and then 3m to free the dwg struct. I also had to fix a couple of internal problems.

    We couldn't use David Bender's hashmap which he took from Android (Apache 2 licensed), and I didn't like it too much neither. So today I sat down and wrote a good int hashmap from scratch, with several performance adjustments, because we never get a key 0 and we won't need to delete keys.
    So it's extremely small and simple, using cache-friendly open addressing, and I got it right at the second attempt.

    Performance with this hash table now got down to 7 seconds.
    Then I also removed the unneeded dwg_free calls from some cmdline apps, because the kernel does it much better then libc malloc/free. 3 minutes for free() is longer than the slowest garbage collector I've ever seen.
    So now processing this 42MB dwg needs 7s.

  • California Can Lead the Way in Open Access
  • Better API testing with the OpenAPI Specification

    If you search the internet for "unexpected API behavior," you'll soon discover that no one likes when an API doesn't work as anticipated. When you consider the increasing number of APIs, continuous development, and delivery of the services built on top of them, it's no surprise that APIs can diverge from their expected behavior. This is why API test coverage is critical for success. For years, we have created unit and functional tests for our APIs, but where do we go from there?

  • Kubernetes at 4 Years Old Continues to Improve Cloud Native Technology

    On June 6, 2014, Joe Beda published the first code commit for the open-source Kubernetes container orchestration project. Four years later, Kubernetes has become a core enabler for cloud native technology and benefits from the support of all the major public cloud providers and many major enterprise IT vendors as well.

    When Beda made the first code commit, he was an engineer at Google. In 2018, Beda is now the co-founder and CTO of Heptio, which provides commercial support and services for Kubernetes. In a video interview with eWEEK, Beda discusses the scope of Kubernetes, what it is and what it isn't as well as providing some insight into what's coming next.

  • Google freezes Android P: Get your shoes on, tire-kicking devs

    With Google freezing the Android P APIs yesterday, both major mobile platforms have shown their hand for 2018. The freeze comes as Google released "Beta 2", which is really the third Developer Preview release of Android P issued so far.

    The API freeze means developers can now compile and submit apps compatible with Android P to the Google Play Store.

    This is the first year in which Google has really invited a range of enthusiasts to come in and kick the tires. Previous Android previews only ran on Google devices, but this year a number of other devices - from Nokia, Sony, Xiaomi, OnePlus, Essential and Vivo - can also get a glimpse of code before it is baked into manufacturers' ROMs. These images will be pushed out shortly.

  • Samsung Chromebook Plus Adds Linux App Support

    Sooner than I honestly expected, it seems that the Crostini Project has made its way to the Developer channel on the Samsung Chromebook Plus.

    As Robby reported in early May, the Crostini Reddit revealed a user who was already up and running with Crostini(sort of) on the ARM-powered Chromebook. Additionally, a number of commits in the Chromium repository gave us some pretty solid evidence that developers had shifted their efforts to making the container tech work outside of the Pixelbook.

    Thanks to a recent update to the Developer channel, we are now seeing reports that ‘Kevin‘ a.k.a the Samsung Chromebook Plus can now run the Linux terminal app just like the Pixelbook does.

  • Samsung Chromebook Plus Now Supports Linux apps

Devuan GNU+Linux 2.0.0 "ASCII"

When I am trying out a desktop distribution, what really tends to divide the field of Linux distributions in my mind is not whether the system uses MATE or Plasma, or whether the underlying package manager uses RPM or Deb files. What tends to leave a lasting impression with me is whether the desktop environment, its applications and controls feel like a cooperative, cohesive experience or like a jumble of individual tools that happen to be part of the same operating system. In my opinion Ubuntu running the Unity desktop and Linux Mint's Cinnamon desktop are good examples of the cohesive approach. The way openSUSE's administration tools work together provides another example. Like them or hate them, I think most people can see there is an overall design, a unifying vision, being explored with those distributions. I believe Devuan falls into the other category, presenting the user with a collection of utilities and features where some assembly is still required. This comes across in little ways. For example, many distributions ship Mozilla's Firefox web browser and the Thunderbird e-mail client together as a set, and they generally complement each other. Devuan ships Firefox, but then its counterpart is the mutt console e-mail program which feels entirely out of place with the rest of the desktop software. The PulseAudio sound mixing utility is included, but its system tray companion is not present by default. Even the system installer, which switches back and forth between graphical windows and a text console, feels more like a collection of uncoordinated prompts rather than a unified program or script. Some people may like the mix-and-match approach, but I tend to prefer distributions where it feels like the parts are fitted together to create a unified experience. What I found was that Devuan provided an experience where I had to stop and think about where items were or how I was going to use them rather than having the pieces seamlessly fit together. However, once I got the system set up in a way that was more to my liking, I appreciated the experience provided. Devuan offers a stable, flexible platform. Once I shaped the operating system a little, I found it to be fast, light and capable. Having a fairly large repository of software available along with Flatpak support provided a solid collection of applications on a conservative operating system foundation. It was a combination I liked. In short, I think Devuan has some rough edges and setting it up was an unusually long and complex experience by Linux standards. I certainly wouldn't recommend Devuan to newcomers. However, a day or two into the experience, Devuan's stability and performance made it a worthwhile journey. I think Devuan may be a good alternative to people who like running Debian or other conservative distributions such as Slackware. I suspect I may soon be running Devuan's Raspberry Pi build on my home server where its lightweight nature will be welcome.
