Thu, 03/04/2014 - 7:45am

KDE today releases the first Alpha version of the next-generation Plasma workspace. This kicks off the public testing phase for the next iteration of the popular Free software workspace, code-named "Plasma Next" (referring to the 'next' Plasma release-see below "A note on versioning and naming"). Plasma Next is built using QML and runs on top of a fully hardware-accelerated graphics stack using Qt 5, QtQuick 2 and an OpenGL(-ES) scenegraph.

Plasma Next is planned to be released as 2014.6 on the 17th of June.

TuxMachines: Meet MediaGoblin, a Decentralized Alternative to YouTube and Flickr

Thu, 03/04/2014 - 7:41am

Running on GNU, MediaGoblin allows user to upload videos, images, audio, and other types of digital media. But, unlike YouTube, Flickr, and Soundcloud, users control their own servers. And, if Webber, Nicholson, and the rest of the MediaGoblin community have their way, each users' media will be stored on Tahoe-LAFS, an encrypted server that does not know what data it stores.

TuxMachines: Per-Cgroup Swap File Support Proposed For Linux

Thu, 03/04/2014 - 6:57am

This small but important change would support a cgroup to swap to a particular file as setup by a new control file. This change is to allow the limiting of cgroups to a given swap file without being able to thrash the entire system's swap file. With this set of three patches, individual cgroups can be limited in their swap capacity.

TuxMachines: Linux Kernel Developers Fed Up With Ridiculous Bugs In Systemd

Thu, 03/04/2014 - 6:33am

When systemd sees "debug" as part of the kernel command-line, it will spit out so much informaiton about the system that it fails to boot... The init system just collapses the system with too much information being sent to the dmesg when seeing the debug option as part of the kernel command-line parameter. Within the systemd bug report it was suggested for systemd not to look for a simple "debug" string to go into its debug mode but perhaps something like "systemd.debug" or other namespaced alternatives. The debug kernel command-line parameter has been used by upstream Linux kernel developers for many years. However, upstream systemd developers don't agree about changing their debug code detection. Kay Sievers of Red Hat wrote, "Generic terms are generic, not the first user owns them."

Reddit: Ghetto cgroups

Thu, 03/04/2014 - 6:12am

Something I found.

Say you want to track child processes but for whatever reason can't use cgroups (no permissions, etc)

Set an environment variable when you start the target process

GROUP=my_ghetto_group mad_spawning_process

Then when you want to do something to them say kill them all.

kill_group() { signal=$1; target_group=$2; for pid in $(ls /proc/ | grep '^[0-9]'); do if [[ -r "/proc/$pid/environ" ]]; then group="$(sed 's/\x00/\n/g' < "/proc/$pid/environ" | grep '^GROUP=' | sed 's/^GROUP=//')" if [[ $group == $target_group ]]; then echo "Killing $signal $pid: ($(cat "/proc/$pid/cmdline" | sed "s/\x00/ /g"))" kill $signal $pid fi fi done } kill_group -SIGTERM my_ghetto_group

Obviously there are problems if process fork while your looking at it but it seems to work well enough.

LXer: Why I’m glad I never abandoned Android for an iPhone

Thu, 03/04/2014 - 5:45am
I've written about and reviewed mobile phones for almost a decade and a half. Everything from flip phones, to BlackBerrys, to today's hottest Android models, and yes, Apple iPhones, have passed through my hands. That experience is why, more than anything, I've ultimately settled on Google Android as my smartphone platform of choice.

Reddit: Can print test page but nothing else

Thu, 03/04/2014 - 5:34am

I have a receipt printer (M-T532AP) I have been able to print the test page from the cups web interface and I can print using "lp <text file>".

I have tried printing from a web browser and a text editor with no luck. I have tried reinstalling cups and the driver with no luck.

I have access to a linux box where the printer is working, (i didn't set it up) I tried to retrace the steps of what the old tech did to get it working with no luck.

The two error messages that I am getting are "Can't feed job data into ghostscript" and "filter failed"

The working machine is running Ubuntu 12.04 The machine I am trying to get working is Lbuntu 13.10

Any help that could be provided would be great
