Lost mime types under kde

Filed under

I downloaded the source to the (video editing) application "kdenlive" (version 0.9 just released), and following the instructions on the kdenlive web site, compiled it, and installed it on my Linux Mageia Cauldron laptop. Maybe I did something wrong, maybe not. Anyway, disaster ensued.

Whenever I launched an app from the panel or the KMenu, I would get an error about missing mimetypes. Logging-out and logging back into KDE didn't help, and popped up a window error dialog listing dozens of applications with missing mime types. Rebooting the system didn't help.

In short, the only way to launch an app was with Alt-F2, or from the command line.

Thrashing around online brought forth few references to this issue, but I did find a brief mention about kdelibs4 and mime types.

So, in desperation, I reinstalled "kdelibs4-core". Under Mandriva/Mageia this can be done from the command line using the "urpmi" utility. To do this, become the root user with su. Then enter:

urpmi --replacepkgs kdelibs4-core

Fortunately this brought my system back to normal. Problem solved.

NATS Messaging Project Joins Cloud Native Computing Foundation

The Cloud Native Computing Foundation (CNCF) voted on March 14 to accept the NATS messaging project as its newest hosted effort. The NATS project is an open-source distributed messaging technology that got its start seven years ago and has already been deployed by multiple organizations including Ericsson, Comcast, Samsung and General Electric (GE). "NATS has room to grow as cloud native adds more use cases and grows adoption, driven by Kubernetes and containers," Alexis Richardson, Chair of the Technical Oversight Committee (TOC) at the CNCF told eWEEK. "CNCF provides a way to scale community and education so that adopters can engage faster and at all levels." Read more

lkml: remove eight obsolete architectures

In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. Read more

If you hitch a ride with a scorpion… (Coverity)

I haven’t seen a blog post or notice about this, but according to the Twitters, Coverity has stopped supporting online scanning for open source projects. Is anybody shocked by this? Anybody? [...] Not sure what the story is with Coverity, but it probably has something to do with 1) they haven’t been able to monetize the service the way they hoped, or 2) they’ve been able to monetize the service and don’t fancy spending the money anymore or 3) they’ve pivoted entirely and just aren’t doing the scanning thing. Not sure which, don’t really care — the end result is the same. Open source projects that have come to depend on this now have to scramble to replace the service. [...] I’m not going to go all RMS, but the only way to prevent this is to have open tools and services. And pay for them. Read more
