  • Leopard Flower firewall – Protect your bytes

    Several months ago, I decided to explore a somewhat obscure topic of outbound per-application firewall control in Linux. A concept that Windows users are well familiar with, it’s been around for ages, providing Windows folks with a heightened sense of – if not practical factual – protection against rogues residing in their system and trying to phone home.

    In Linux, things are a little different, but with the growing flux of Windows converts arriving at the sandy shores of open-source, the notion of need for outbound control of applications has also risen, giving birth to software designed to allay fears if not resolve problems. My first attempt to play with Leopard Flower and Douane was somewhat frustrating. Now, I’m going to revisit the test, focusing only on the former.

    [...]

    Leopard Flower firewall is an interesting concept. Misplaced, though, for most parts. It caters to a Windows need that does not exist on Linux, and to be frank, has no place in the Microsoft world either. Then, it also tries to resolve a problem of control and knowledge by requiring the user to exercise the necessary control and knowledge. But if they had those to begin with, they wouldn’t need to dabble in per-application firewalls. Furthermore, the software is still fairly immature. There are at least half a dozen little things and changes that can be implemented to make lpfw more elegant, starting with installation and followed by service and GUI model, prompts, robustness, and a few others.

  • Clair 1.0 Brings Advances in Container Security

    CoreOS pushes the open-source container security project to the 1.0 milestone and production stability.
    As container use grows, there is an increasing need to understand from a security perspective what is actually running in a container. That's the goal of CoreOS' Clair container security project, which officially hits the 1.0 milestone today, in an effort to help organizations validate container application security.

  • Which OpenGL implementation is my Qt Quick app using today?
    Qt Quick-based user interfaces have traditionally been requiring OpenGL, quite unsurprisingly, since the foundation of it all, the Qt Quick 2 scenegraph, is designed exclusively with OpenGL ES 2.0 (the top of the line for mobile/embedded at the time) in mind. As you may have heard, the graphics API story is a bit more inclusive in recent Qt versions, however the default OpenGL-based rendering path is, and is going to be, the number one choice for many applications and devices in the future. This raises the interesting question of OpenGL implementations.
  • Should you still be using QGraphicsView?
    There was a time when the Qt Graphics View Framework was seen as the solution to create modern user interfaces with Qt. Now that Qt Quick 2 has matured does the Graphics View Framework still have a place in Qt?

    This year's Google Code In was awesome as before . There were instances of tasks successfully completed by the students . Out of 12 unique tasks 11 tasks were successfully attempted . The students were enthusiastic till the very end of the program. Most of the students solved multiple tasks that provided us with varied ideas .

Raspberry Pi: A closer look at Raspbian PIXEL

Over the past three posts, I have looked at a number of different Linux distributions for various models of the Raspberry Pi - including SUSE/openSUSE, Fedora, Manjaro and Ubuntu MATE, and PiCore Linux. What I haven't done yet is look at the latest version of the Raspberry Pi Foundation's own Linux distribution, Raspbian with their PIXEL desktop. So I will look at that first, and then I will wrap this series up. I know that I just recently wrote about Raspbian PIXEL, but that was a sort of "what's new" overview, and in this post I want to go much deeper, and in a lot more detail, to provide some comparison to the other Linux distributions that I have been testing. So please bear with me... Read more
