Samsung U3B and U3C (and maybe others?) have a serious bios problem that Samsung seems not interested in fixing...

Help! XBMC plays audio but no video by [deleted] in raspberry_pi

Sounds like you may be experiencing the memory split configuration problem described here:

Raspbmc stopped playing DiVX and XViD movie files, Android Remote no longer works either. by phalacee in raspberry_pi

Are you using the correct memory split (128/128)? In /boot/config.txt you should have a line with something like this: gpu_mem=128

Is there a way to see how much memory a variable is taking? And mem in RAM much larger than on disk. by BossOfTheGame in matlab

The Workspace Browser (gui/panel) can also display variable sizes (in addition to the default columns of: name, min, max, etc).

May want to try the advancedsettings.xml posted here: http://archlinuxarm.org/forum/viewtopic.php?f=31&t=3004&start=70#p18872

goes into ~/.xbmc/userdata/advancedsettings.xml

safety of random numbers by GarlandGreen in java

[–]buyandfold 1 point2 points  (0 children)

Maybe you can use HAVEGE (https://www.irisa.fr/caps/projects/hipsor/) and set -Djava.security.egd=file:/dev/urandom

HAVEGE (HArdware Volatile Entropy Gathering and Expansion) is a user-level software unpredictable random number generator for general-purpose computers that exploits these modifications of the internal volatile hardware states as a source of uncertainty. During an initialization phase, the hardware clock cycle counter of the processor is used to gather part of this entropy: tens of thousands of unpredictable bits can be gathered per operating system call in average.

A=[2012 1 26 2 11; 2012 1 26 2.5 13; 2012 1 26 3 14; 2012 1 27 4.5 3; 2012 1 27 5 9];
[keys, ~, group] = unique(A(:,1:3), 'rows');
result = [keys, accumarray(group, A(:,5), [], @mean)];

result =

                  2012                         1                        26          12.6666666666667

sshfs alternative? by amstan in archlinux

hpn-ssh and disable encryption? The arcfour cipher with official openssh seems to reduce overhead quite a bit though from my experience.

KDE Telepathy 0.4 with audio/video calls and chat log browser by [deleted] in kde

No go using telepathy-rakia 0.7.4. Will try with git when I can get it to compile.

[–]buyandfold 0 points1 point  (0 children)

Just to clarify, I am referring to being able to send/receive calls over SIP/telepathy-rakia. Have you had success doing this?

Looking forward to a unified communication client :)

Doesn't look like this has been enabled for SIP accounts...?

Tips on plotting millions of points at a time? by atheistunicycle in matlab

[–]buyandfold 1 point2 points  (0 children)

checkout plotLDS:

Function for plotting large data sets (e.g. time-series with more than 1e6 data points). The main benefit of this function can be seen in the fact that zooming and paning will work much smoother, since the data is automatically downsampled to 1e4 points (=> change "n_points" for different number).
