Kernel space: How much memory am I really using?

Filed under

Anybody who has tried to figure out why a Linux system is running short of memory can attest that the memory usage information made available by the kernel is, at best, difficult to use. Matt Mackall has recently been working on a set of patches aimed at improving this situation.

Linux and live CD's. What's the attraction?

Filed under

Every Linux distribution available seems to be coming out as a live CD. A reader (you know who you are Smile has asked me how these live CD's work and what is the use of them. Here is my attempt at providing an answer.

Vector Linux - Chaucer's Beautiful Hag

Filed under

n the Wife of Bath's Tale, part of Geoffrey Chaucer's "The Canterbury Tales", a knight caught in the act of raping a woman is sentenced to discover what women truly desire. To help our modern readers understand how that might be considered punishment, it's a lot like sending someone to discover why Windows crashes without explanation.

Linux Minty Fresh

Filed under

Linux Mint is the prettiest incarnation of the Ubuntu family, yet it doesn't seems to get the same attention as its *buntu parents. I've been wanting to be able to use Mint since my first little test run of a beta of 2.2, but at that time wireless support shattered those plans.

Open source becoming more innovative?

Filed under

Years ago, I remember pontificating that open source would never touch the application market. Narrowly viewing open source through the prism of the day, I said things like this (to John Koenig at IT Managers Journal):

Filed under

Last Wednesday, a company called Falling Leaf Systems announced the availability of an alpha of something called the Alky Project. The Alky Project has a lofty goal: to liberate DirectX 10 gaming from the confines of Vista and bring it first to Windows XP, and then to Linux and OS X.

Mac and Linux attacks set to rise

Filed under

Speaking to consumer PC mag PC Pro, security guru Eugene Kaspersky said that the lukewarm reception of Vista will result in defections to Mac OS and Linux, thus making them more attractive targets for malware writers.

Mozilla extends Firefox 1.5 support

Filed under

Mozilla seems to be having a hard time pulling the plug on Firefox 1.5.

After today, the open-source group planned to stop shipping security and stability updates for Firefox 1.5 but now I'm hearing that support has been extended to the middle of May.

a kute little story

Filed under

my friend andy came over the other day and told me a rather nice little kde related story that i thought i'd pass on:

a client of his has some linux servers that are sitting in a local colo centre. the isp running the colo messed up some internal routing and half his servers could no longer talk to the other half inside the colo (though everything was visible and reachable from the outside).

Microsoft Corp. today spelled out exactly how users of Windows Vista betas and release candidates can shift to the final code, and warned that beginning June 1, preview-equipped PCs will automatically reboot every two hours.

Getting Xubuntu Feisty to bend to my will

Filed under

I made some progress -- and some discoveries -- today with my Xubuntu 7.04 Feisty installation on the Maxspeed Maxterm thin client.

First of all, while I think we can all agree that the GIMP, in its heaviness, doesn't really fit in with the Xubuntu philosophy of lighter apps for a lighter window manager.

Typical customization of a Ubuntu 7.04

Here is my typical customization on Ubuntu 7.04 after installation. I am sure everyone who read this blog regularly knows that I am running Ubuntu on my production system. Ubuntu’s performance, features, and all blah.. blah.. all every one in this tux world knows. So I want to present here what I customize in my shiny new Ubuntu 7.04 (Feisty Fawn).

Windows by necessity: making MS-Windows more like GNU/Linux

Filed under

MS-Windows can be a good operating system.

How can I change the default size of an inode when I create an ext2/ext3 filesystem?

Filed under

It is possible to define a non-standard sized inode by using the mke2fs tool with an undocumented option, -I. The size of the inode has to be a power of two and between the size of EXT2_GOOD_OLD_INODE_SIZE (128 bytes) and size of blocks in bytes. One reason for doing this could be that user is going to use extended attributes.

  • Pixeluvo Review | Photo Editor for Linux & Windows
    A review of Pixeluvo, a great photo editor available on Linux and Windows. Pixeluvo is not free or open source.
  • Blit, A Retrospective On My Largest Project Ever
    I’ve always been someone who’s liked art and programming. Especially combining the two. One of my favorite genres is pixel art, or sprites as they are also known. I’ve dabbled in making a few other art programs before, but nothing like this. Originally Blit supposed to be only a sprite animation tool that had a modern look and feel, but my ideas for it grew greater (*sigh* feature creep). There are many other sprinting tools out there like GrafX2, Aseprite, (and other 2D animation programs like TVPaint). I’m not saying that it’s wrong that they make their own GUI toolkit, but it feels kind of odd. I really wanted to bring these types of programs out of the days of the Amiga. After doing some initial research, I settled on using Qt.

  • FunYahoo++: New Yahoo Messenger Plugin For Pidgin / libpurple [PPA]
    Yahoo retired its old Messenger protocol in favor of a new one, breaking compatibility with third-party applications, such as Pidgin, Empathy, and so on. Eion Robb, the SkypeWeb and Hangouts developer, has created a replacement Yahoo prpl plugin, called FunYahoo++, that works with the new Yahoo Messenger protocol. Note that I tested the plugin with Pidgin, but it should work with other instant messaging applications that support libpurple, like BitlBee or Empathy.
  • GCC Lands Loop Splitting Optimization
    The latest GCC 7 development code has an optimization pass now for loop splitting.
  • GCC 7 To End Feature Development Next Month
    Friday's GCC 7 status report indicates the feature freeze is coming up in just a few weeks. Red Hat developer Jakub Jelinek wrote in the latest status report, "Trunk which will eventually become GCC 7 is still in Stage 1 but its end is near and we are planning to transition into Stage 3 starting Nov 13th end of day time zone of your choice. This means it is time to get things you want to have in GCC 7 finalized and reviewed. As usual there may be exceptions to late reviewed features but don't count on that. Likewise target specific features can sneak in during Stage 3 if maintainers ok them."
  • GNU Parallel 20161022 ('Matthew') released [stable]

  • Unifont 9.0.03 Released
    Unifont 9.0.03 is released. The main changes are the addition of the Pikto and Tonal ConScript Unicode Registry scripts.
  • PATHspider 1.0.0 released!
    In today’s Internet we see an increasing deployment of middleboxes. While middleboxes provide in-network functionality that is necessary to keep networks manageable and economically viable, any packet mangling — whether essential for the needed functionality or accidental as an unwanted side effect — makes it more and more difficult to deploy new protocols or extensions of existing protocols. For the evolution of the protocol stack, it is important to know which network impairments exist and potentially need to be worked around. While classical network measurement tools are often focused on absolute performance values, PATHspider performs A/B testing between two different protocols or different protocol extensions to perform controlled experiments of protocol-dependent connectivity problems as well as differential treatment.

Leftovers: KDE

  • Happy 20th birthday, KDE!
    KDE turned twenty recently, which seems significant in a world that seems to change so fast. Yet somehow we stay relevant, and excited to continue to build a better future. Lydia asked recently on the KDE-Community list what we were most proud of.
  • SETI – Week of Information Technology
  • KDevelop for Windows available on Chocolatey now
    Which is already great in itself! But now it's also possible to install it via the super popular Windows package manager for Windows, Chocolatey.
  • colord-kde 0.5.0 released!
    Last official stable release was done more than 3 years ago, it was based on Qt/KDE 4 tech, after that a few fixes got in what would be 0.4.0 but as I needed to change my priorities it was never released. Thanks to Lukáš Tinkl it was ported to KF5, on his port he increased the version number to 0.5.0, still without a proper release distros rely on a git checkout.
  • Call for attendees Lakademy 2017
    As many of you know, since 2012 we organize the Lakademy, a sort of Latin American Akademy. The event brings together KDE Latin American contributors in hacking sessions to work on their projects, promo meetings to think KDE dissemination strategies in the region and other activities.
  • Plasma 5 Desktop on FreeBSD Branding
    The FreeBSD packages of KDE software — the KDE 4 desktop, and soon KDE Frameworks 5 and Plasma 5 Desktop and KDE Applications — have traditionally been shipped pretty much as delivered from the upstream source. We compile, we package, and there is very little customization we do as a “distro”. The KDE 4 packages came with a default wallpaper that was a smidgen different from the one shipped with several Linux distro’s. I think Ivan Cukic did that artwork originally. For Plasma 5 Desktop, we also wanted to do a tiny bit of branding — just the default wallpaper for new users, mind.
  • A bit on Tooling
    So on the weekend I also worked on updating Qt 5.6.1 to Qt 5.6.2 on FreeBSD, which involves using new and scary tools as well. Power tools, they can be really useful, or they can take off a finger if you’re not careful. In this case it was Phabricator, which is also used in KDE — but not everywhere in KDE. For FreeBSD, the tool is used to review updates to ports (the packaging instructions), so I did an update of Qt from 5.6.1 to 5.6.2 and we handled the review through FreeBSD’s Phab. The ports infrastructure is stored in SVN, so the review is relatively straightforward: update the ports-tree checkout, apply your changes, use arc to create or update a review request. I was amazed by how painless it was — somehow I’d been frightened. Using the tool once, properly, makes a big difference in self-confidence.
  • Krita 3.1 second beta.
    The Krita 3.1 beta come with a full features and fixes. The linux version to download your krita-3.0.91-x86_64.appimage.
  • Second Beta for Krita 3.1 Available
    We’re still fixing bugs like madmen… And working on some cool new features as well, but that’s for a later release. In any case, here is the second Krita 3.1 beta! Yes, you’re reading that correctly. Originally, we had planned to use 3.0.2 as the version for this release, but there is so much news in it that it merits a bigger version bump.


  • Consequences of the HACK CAMP 2016 FEDORA + GNOME

  • GNOME Shell Making It Easy To Launch Apps/Games For Optimus / Dual GPU Systems
    With the GNOME 3.24 desktop that's currently in development the latest GNOME Shell code has support for easily letting the user launch an app on a dedicated GPU when applicable for handling NVIDIA Optimus use-cases of having integrated and discrete GPU laptops. When a dual-GPU system is detected, a menu item will be added to opt for "Launch using Dedicated Graphics Card", per this commit. The GNOME Shell change for supporting discrete GPUs was made and when the user opts to launch on the dedicated GPU, the DRI_PRIME=1 environment variable will automatically be set for that new program/game.
