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.

Command Line Heroes Launched

  • Red Hat launches new podcast series, Command Line Heroes
    Technology has become so integrated into our daily lives that it can be easy to take it for granted. But we’ve only gotten to where we are today because of the command line heroes that shaped the industry - and continue to do so. Command line hero. What does that really mean? To us it’s the developers, programmers, hackers, geeks and open source rebels - the people who are on the front line, transforming technology from the command line up. The biggest technology advancements and innovations didn’t happen by accident. They were made possible through the passion, creativity and persistence of technologists around the world.
  • Command Line Heroes
    I’ve been looking forward to this for quite a while, ever since it was announced: today, the first two episodes of Command Line Heroes were published. Command Line Heroes, or CLH for short, is a series of podcasts that tells the stories of open source. It’s hosted by Saron Yitbarek, of CodeNewbie fame, and sponsored by Red Hat.

NethServer, Red Hat, and Fedora

  • Fixing flatpak startup times
    A lot of people have noticed that flatpak apps sometimes start very slowly. Upon closer inspection you notice this only happens the first time you run the application. Still, it gives a very poor first time impression. So, what is causing this, and can we fix it? The short answer to this is font-cache generation, and yes, I landed a fix today. For the longer version we have to take a detour into how flatpak and fontconfig works.
  • Fedora 28 wallpaper contest now open -- submit your image to the Linux distro!
    One of the first things I do after installing a new Linux distribution is set a different wallpaper. Why? Desktop pictures really inspire me -- my mood can be positively altered by a beautiful image. The default wallpaper is often boring. For the most part, I prefer images of nature with bright colors. After all, if I am stuck indoors working on my computer, a wallpaper of the beach, mountains, or a colorful bird, for instance, can transport me to the outdoors -- in my mind. Sadly, not every distro has beautiful high-quality images. Fedora, however, often does -- thanks to its "supplemental" wallpapers. What is particularly cool  about that operating system, is that it regularly accepts wallpaper submissions from the community as part of a contest. In other words, anybody can potentially contribute to a new version of the distro by simply uploading a photo, drawing, or other picture. Fedora 28 is the upcoming version of the OS, and the developers are now calling for wallpaper submissions for it. Will you submit an entry to the contest?

OSS Leftovers

  • Google's Kelsey Hightower talks Kubernetes and community
    Google developer advocate Kelsey Hightower says that he always figured that the (now wildly successful) Kubernetes container orchestration platform "would get big on its own at some point." He shared some of the reasons he sees for Kubernetes' success in a podcast recorded in December at CloudNativeCon in Austin. The first is that Kubernetes is an effective platform on which to do other things. It provides "better primitives than I had before" as Hightower puts it. At the same time, he says that this is something people misunderstand about Kubernetes. "It's not the end game," he says. Rather, at some point, it increasingly becomes "the new platform for building other platforms."
  • A FOSS Year Resolution
    It’s that time of year again. The time when some people are taking a long hard look at their lives and trying to decide what they want to change about themselves over the course of the next year. Some of us want to lose weight, or exercise more, or spend more time with our kids. The trouble is only about 9% of these resolutions actually happen.
  • Do not limit yourself
    The motto of Learn yourself, teach others is still very strong among us. We try to break any such stupid limits others try to force on our lives. We dream, we try to enjoying talking about that book someone just finished. We discuss about our favorite food. I will end this post saying one thing again. Do not bound yourself in some non existing limits. Always remember, What a great teacher, failure is (I hope I quoted Master Yoda properly). Not everything we will try in life will be a super successful thing, but we can always try to learn from those incidents. You don’t have to bow down in front of anyone, you can do things you love in your life without asking for others’ permissions.
  • Benjamin Mako Hill: OpenSym 2017 Program Postmortem
    The International Symposium on Open Collaboration (OpenSym, formerly WikiSym) is the premier academic venue exclusively focused on scholarly research into open collaboration. OpenSym is an ACM conference which means that, like conferences in computer science, it’s really more like a journal that gets published once a year than it is like most social science conferences. The “journal”, in iithis case, is called the Proceedings of the International Symposium on Open Collaboration and it consists of final copies of papers which are typically also presented at the conference. Like journal articles, papers that are published in the proceedings are not typically published elsewhere.
  • NVDA and Firefox 58 – The team is regaining strength
    A week before the Firefox 57 “Quantum” release in November, I published an Article detailing some bits to be aware of when using Firefox and the NVDA screen reader together. In Firefox 58, due on January 23, 2018, the reliable team is regaining strength in playing well together and offering you good and fast web accessibility. After the Firefox 57 release, due to many changes under the hood, NVDA and Firefox temporarily lapsed in performance. Statistics quickly showed that about two thirds of the NVDA user base stayed with us despite of this. So to all of you who stuck with us on this difficult release: Thank you! Many of the others moved to the extended support release of Firefox 52. Thank you to those of you as well, you decided to stick with Firefox! Also, statistics show that barely any of those of you who stuck with 57 decided to turn off multi-process Firefox, but instead used the new technology, and some of you even reported problems to us.
  • Retpoline-enabled GCC
    There will be upstream backports at least to GCC 7, but probably pretty far back (I've seen people talk about all the way to 4.3). So you won't have to run my crappy home-grown build for very long—it's a temporary measure. :-) Oh, and it made Stockfish 3% faster than with GCC 6.3! Hooray.

  • Spectre and Meltdown patches causing trouble as realistic attacks get closer
    Applications, operating systems, and firmware all need to be updated to defeat Meltdown and protect against Spectre, two attacks that exploit features of high-performance processors to leak information and undermine system security. The computing industry has been scrambling to respond after news of the problem broke early a few days into the new year. But that patching is proving problematic. The Meltdown protection is revealing bugs or otherwise undesirable behavior in various drivers, and Intel is currently recommending that people cease installing a microcode update it issued to help tackle the Spectre problem. This comes as researchers are digging into the papers describing the issues and getting closer to weaponizing the research to turn it into a practical attack. With the bad guys sure to be doing the same, real-world attacks using this research are sure to follow soon.
  • Finnish firm detects new Intel security flaw
    new security flaw has been found in Intel hardware which could enable hackers to access corporate laptops remotely, Finnish cybersecurity specialist F-Secure said on Friday. F-Secure said in a statement that the flaw had nothing to do with the "Spectre" and "Meltdown" vulnerabilities recently found in the micro-chips that are used in almost all computers, tablets and smartphones today. Rather, it was an issue within Intel Active Management Technology (AMT), "which is commonly found in most corporate laptops, (and) allows an attacker to take complete control over a user's device in a matter of seconds," the cybersecurity firm said.
