ACPI, firmware and your security

Filed under

Ubuntu

If you read the catalogue of spy tools and digital weaponry provided to us by Edward Snowden, you’ll see that firmware on your device is the NSA’s best friend. Your biggest mistake might be to assume that the NSA is the only institution abusing this position of trust – in fact, it’s reasonable to assume that all firmware is a cesspool of insecurity courtesy of incompetence of the worst degree from manufacturers, and competence of the highest degree from a very wide range of such agencies.

Ubuntu 16.04 LTS

It is always a big deal when Canonical releases a new long-term support version of Ubuntu. Despite Ubuntu's important place in the Linux distribution ecosystem, I should admit right off the bat that I am not a regular user of Ubuntu. I try out each new release of the desktop version Ubuntu and occasionally use Ubuntu Server, but I tend to use Fedora and CentOS for almost all of my daily desktop and server needs. Still, I've always been fascinated by what Canonical is doing with Ubuntu and their Unity desktop environment. Below, I take a look at Ubuntu 16.04 LTS and share my thoughts on the Unity desktop environment and the distribution as a whole. Read more

  • KDE Akonadi Support For Microsoft Exchange
  • Akonadi Resource for Microsoft Exchange Web Services (EWS)
    Whether you are a Microsoft hater or a lover, when you have ever had a chance to work for a medium or large corporation, you have probably stumbled upon Microsoft Exchange mail server. While it can be made to talk to regular e-mail clients using standards such as IMAP, POP3 and SMTP, some corporate admins choose not to enable any of the standard mail protocols leaving the user with no choice other than to use Microsoft Outlook. Even if it is possible to use regular e-mail clients they will not be able to explore the full potential of Exchange, as it is not only a mail server but rather a groupware server which includes support for calendar, tasks, contacts and many more.
  • Evaluation of the Qt Quick Scene Graph Performance
    QPainter, which is the base of drawing in KStars, uses an imperative way whereas QtQuick Scene Graph utilizes declarative paradigm. In Scene Graph you add some set of "nodes" (classes with prefix QSG) to the root node that is returned by calling QQuickItem::updatePaintNode() whenever you want to render QQuickItem and manipulate them during the runtime (change position, geometry, material, etc.) This gives possibilities to perform some optimization like batching the nodes to draw them in fewer calls to OpenGL, which can be of tremendous help for us in drawing stars, for example.
  • Hello World!
    As the title suggests it is a lite version for mobile/tablets, slow machines like budget laptops, netbooks, single-board computers like Raspberry Pi, etc. One of the main differences between desktop and lite versions is that the graphics of the latter is based on QML/QtQuick. KStars Lite is built bearing in mind the differences between mouse/touch interfaces and the graphical frontend will be designed according to touch interfaces of mobile platforms.
