Sun Microsystems is contributing Project Looking Glass, based on Java™ technology, to the open source community.

Project Looking Glass is an exploratory project to bring innovative 3D features to the desktop environment. The desktop interface will offer an intuitive, new 3D environment to interact with desktop applications featuring window transparency, rotation, zoom, multiple desktop workspaces, and miniaturization. Project Looking Glass offers a platform to realize a far richer and more entertaining user experience for existing and new applications in 2D or 3D. The technology enables developers to build highly visual 3D desktops and applications that will run on Linux systems such as Sun’s Java Desktop System. The Solaris™ environment will be supported in the near future.

If your vim have auto indent enabled, you may facing this problem. Vim are too smart to help you indent copied source code, and the comment line will kill your pasting very much. I usually do copy and paste source code from ebook or web page to a file so that I can compile and run for test. In this case vim is not helping. I use cat instead.

Let me tell you, I’m a busy man. I’m always on the go and my trusty laptop is the only thing to keep me company much of the time. Despite being here, there and everywhere I still need access to my files and folders at home. But how can I access my files, securely, from anywhere on the planet? It is simple with SSH.

If you’re not familiar with SSH you’ll definitely want to check it out. SSH stands for Secure SHell and is probably one of the most used programs on the internet with its long list of uses. It is always encrypted, always secure and easy to use. I have long used it on a daily basis and here is how you can do the same.

The zip program is a useful tool for archiving or transferring a set of files. A simple command like "zip archive dir" can quickly package a whole directory into a single compressed archive file (often called "zip file"). Depending on the type of files being packaged, the size of the archive often gets compressed to a fraction of the size of the original files.

While not perfect, support for scanners on Linux is constantly improving; just check the list of devices supported by SANE (Scanner Access Now Easy -- the scanning suite for Linux and other Unix-like systems). One thing that's still missing though is a way to make a scanner's buttons work on Linux. That's what this tutorial is about.

I run Ubuntu 6.10 (Egdy Eft) on my desktop system, but all required programs are available on most Linux distributions and, possibly, BSD variants. The actual programs you will need for this setup are:

I'm sure everyone reading here has used "-exec" with "find"; for example:

find . -name core -exec rm {} \;

When I want to do something more complex to each found file, I usually pass the name to another script:

find . -exec my shellscript {} \;

The most interesting and dangerous phase of this learning experience is when the start mucking about in the Command Line Interface (CLI). It’s exciting for them to suddenly feel powerful on their own computer. They can make sweeping changes with the tap of a few keys.

Sadly, they do this. A lot.

Before they really know what they’re doing. So I’ve implemented a few quick changes to their machines to always prompt before removing, copying or moving files.

I have switched to Xubuntu a few months ago coming from Kubuntu. In Kubuntu I liked the (already available) option of setting up a list of image files and have them randomly displayed as background image on the desktop. This was one of the things I have missed so far in Xfce. This small howto shows you how you can randomly display background wallpapers in XFCE.

Vulkan FOSS Adoptions

  • SDL 2.0.6 released, introduces Vulkan support
    The cross-platform development library has seen the release of its latest version. Quite a few exciting changes this time around, including support for Vulkan and more types of gamepads. SDL [Official Site] is something that has been used in quite a diverse array of projects and plenty of game ports that have made their way to Linux have taken advantage of it. The latest release has its fair share of general improvements but most noticeable is the implementation of Vulkan support. This hopefully will make it easier for developers to take advantage of the Vulkan API and help it gain more traction.
  • X.Org Foundation Has Become A Khronos Adopter
    The X.Org Foundation board announced during this week's XDC2017 summit that they have officially completed the paperwork to become a Khronos adopter. The X.Org Foundation is now considered a pro-bono adopter for The Khronos Group so that the community-based open-source drivers targeting Khronos APIs for conformance can submit conformance test results and become a certified implementation.

Security: DHS on Potential Voting Machines Cracking, Joomla Patches Critical Flaw

  • DHS tells 21 states they were Russia hacking targets before 2016 election
  • 1. WikiLeaks, Russian edition: how it’s being viewed
    Russia has been investing heavily in a vision of cyberdemocracy that will link the public directly with government officials to increase official responsiveness. But it is also enforcing some of the toughest cybersecurity laws to empower law enforcement access to communications and ban technologies that could be used to evade surveillance. Could WikiLeaks put a check on Russia’s cyber regime? This week, the online activist group released the first of a promised series of document dumps on the nature and workings of Russia’s surveillance state. So far, the data has offered no bombshells. “It’s mostly technical stuff. It doesn’t contain any state contracts, or even a single mention of the FSB [security service], but there is some data here that’s worth publishing,” says Andrei Soldatov, coauthor of “The Red Web,” a history of the Soviet and Russian internet. But, he adds, “Anything that gets people talking about Russia's capabilities and actions in this area should be seen as a positive development.”
  • Joomla patches eight-year-old critical CMS bug
    Joomla has patched a critical bug which could be used to steal account information and fully compromise website domains. This week, the content management system (CMS) provider issued a security advisory detailing the flaw, which is found in the LDAP authentication plugin. Lightweight Directory Access Protocol (LDAP) is used by Joomla to access directories over TCP/IP. The plugin is integrated with the CMS. Joomla considers the bug a "medium" severity issue, but according to researchers from RIPS Technologies, the problem is closer to a critical status.
  • Joomla! 3.7.5 - Takeover in 20 Seconds with LDAP Injection
    With over 84 million downloads, Joomla! is one of the most popular content management systems in the World Wide Web. It powers about 3.3% of all websites’ content and articles. Our code analysis solution RIPS detected a previously unknown LDAP injection vulnerability in the login controller. This one vulnerability could allow remote attackers to leak the super user password with blind injection techniques and to fully take over any Joomla! <= 3.7.5 installation within seconds that uses LDAP for authentication. Joomla! has fixed the vulnerability in the latest version 3.8.

OpenSUSE fonts – The sleeping beauty guide

Pandora’s box of fonts is one of the many ailments of the distro world. As long as we do not have standards, and some rather strict ones at that, we will continue to suffer from bad fonts, bad contrast, bad ergonomics, and in general, settings that are not designed for sustained, prolonged use. It’s a shame, because humans actually use computers to interface with information, to READ text and interpret knowledge using the power of language. It’s the most critical element of the whole thing. OpenSUSE under-delivers on two fonts – anti-aliasing and hinting options that are less than ideal, and then it lacks the necessary font libraries to make a relevant, modern and pleasing desktop for general use. All of this can be easily solved if there’s more attention, love and passion for the end product. After all, don’t you want people to be spending a lot of time interacting, using and enjoying the distro? Hopefully, one day, all this will be ancient history. We will be able to choose any which system and never worry or wonder how our experience is going to be impacted by the choice of drivers, monitors, software frameworks, or even where we live. For the time being, if you intend on using openSUSE, this little guide should help you achieve a better, smoother, higher-quality rendering of fonts on the screen, allowing you to enjoy the truly neat Plasma desktop to the fullest. Oh, in the openSUSE review, I promised we would handle this, and handle it we did! Take care. Read more
