KDE Frameworks 5.3 and Plasma 2.1 – First Impressions

Ken Vermette has done a write-up on his experience with the new KDE desktop encompassing Frameworks 5.3 and Plasma 2.1. For starters, some patience is still needed for apps to be ported to KF5, and most of them will be KF4-based for now. Many of the widgets you may have used don’t exist yet either, but the good news is that the Plasma goodies which do make an appearance are universally improved. The new search widget is shockingly fast and the notifications tray has been reworked. Visual outlook of desktop has been simplified and things don’t feel so tightly packed together anymore. The system settings application has been completely regrouped more by goal than underlying mechanics. Unfortunately the desktop stability leaves a lot to desire: there was several crashes and Plasma had at one point managed to forget colour and wallpaper settings. However the developers seem to be knowing what they are doing, and there’s a real feeling that this software will reach rock-solid stability very quickly given the state of it as it stands.

Tips for Securing Your Secure Shell

As you may have heard, the NSA has had some success in cracking Secure Shell (SSH) connections. To respond to these risks, a guide written by Stribika tries to help you make your shell as robust as possible. The two main concepts are to make the crypto harder and make stealing keys impossible. So prepare a cup of coffee and read the tutorial carefully to see what could be improved in your configuration. Stribika gives also some extra security tips: don’t install what you don’t need (as any code line can introduce a bug), use the kind of open source code that has actually been reviewed, keep your software up to date, and use exploit mitigation technologies.

New Contiki OS Network Regression Test Framework

Contiki, the open source operating system for the Internet of Things, just got a regression test framework ported over from Thingsquare Mist that allows the Contiki developers to test the entire system on 9 platforms, 4 CPU architectures, and 1021 network nodes, for every new commit.


Some have argued that being a framework, it should have been written in C++ rather than C, and that’s is essentially nothing more than a bunch of libraries and APIs…  However, others point to the fact that, since it’s meant to run on microcontrollers (with only kilobytes of RAM), C is still the best choice for it’s smaller compiled footprint, as OO is still more of a luxury when it comes to embedded programming, etc…

Any thoughts?
