tl;dr: you can use kexec to stage a kernel upgrade in-memory without the need for a full reboot. Your system will reload the new kernel on the fly and activate it. There will be a service restart of every running service as the new kernel is loaded, but you skip the entire bootloader & hardware initialization.
IBM Interconnect 2017 is coming up next month in Las Vegas. Last year’s conference was a whirlwind of useful talks, inspiring hallway conversations, and great networking opportunities. I was exhausted by the week’s end, but it was totally worth it.
The good folks at KDE managed to engage a market of Linux desktop users underserved by other distribution models. Or, maybe it’s just me.
KDE has a long history in the desktop ecosystem. It was the first Linux desktop I was exposed to back in 2006. Back then, it was on OpenSUSE and it was clean and functional. For some reason after that, installing KDE had never really appealed to me. I’ve tested it out briefly when poking around at what the OpenSUSE guys were doing and I’ve run Kubuntu for brief snippets. For years, I’ve been trying to find out what type of desktop user I am and which distro fits my needs.
The KDE-FreeBSD team bumped Qt to 5.7.1 and KDE Frameworks to 5.31.0 in official ports last week, so we’re fairly up-to-date in that department. On FreeBSD, we still fully support Qt4 next to Qt5, so some of the delay in getting this stuff in is due to some shuffling of install locations. In particular, we’ve added qt-chooser in this round of updates, so that qmake is qmake — and no longer qmake-qt4 or some other suffixed binary. We use qt-chooser to switch out one or the other. Checking that this doesn’t break anything else — or at least making sure that everything still compiles — is what took the most time this round of updates.
Following "United" theme, there is also "Simple Menu" launcher for KDE Plasma 5.9. It's minimal, a smaller form of full screen menu; it's also clean, showing all applications at once. Honestly, it's UI is similar to Pantheon Menu in elementary OS but including categories. If you like horizontal-oriented menu, Simple Menu is suitable for you. It's available to install from KDE Store. Thanks to Sho for creating Simple Menu.
Some time ago I posted a blog post about how I packed telegram desktop client for flatpak. I’ve been updating it since then in some reasonable intervals as I don’t have time to update it more often and mostly because the telegram client’s build system breaks my build quite oftenly. Recently I discovered that someone managed to patch telegram to use system Qt libraries instead of building own patched Qt and building linking it statically. After some time I managed to adjust those patches and make them work with my build which allows me to use Qt from KDE runtimes. Here are new instructions how to get this work:
Let’s say you got a 64-bit ARM device running Android. For instance, the Tegra X1-based NVIDIA Shield TV. Now, let’s say you are also interested in the latest greatest content from the dev branch, for example to try out some upcoming Vulkan enablers from here and here, and want to see all this running on the big screen with Android TV. How do we get Qt, or at least the basic modules like QtGui, QtQuick, etc. up and running on there?
