TuxMachines: The Linux Kernel Bang-Bang Thermal Governor Is Banging

Tuesday 22nd of July 2014 04:27:43 PM

The Bang-bang thermal governor remains under discussion on the kernel mailing list after patches for it originally appeared a few months back. Bang-bang will hopefully be ready for an upcoming kernel release (Linux 3.17?) and the latest technical discussion about it can be found via the LKML archives.

One Linux kernel driver already planning to utilize the Bang-bang thermal governor is the "Acerhdf" driver that serves as the fan driver for Acer's Aspire One and other Acer systems where it has a simple fan that only supports being on or off. Up to now the acerhdf driver has handled its own on-off controls by post-manipulating the kernel's thermal subsystem trip point handling but will now be able to utilize the unified Bang-bang governor.

Tuesday 22nd of July 2014 04:24:42 PM

I know unity should be my first option, but are there other options? I prefer light weight things like XFCE rather than unity even for desktops.

Reddit: Does anyone actually still use the lightweight alternative to LibreOffice like Abiword and Gnumeric?

Tuesday 22nd of July 2014 12:58:21 PM

I was doing some house keeping of old backups recently and came across a 10 year old project of mine where I intended to write a light weight PowerPoint replacement for GTK+ to complement Abiword and Gnumeric. While the actual code itself isn't much use(I didn't get very far), it did get me thinking whether or not the idea was still valid.

But before I put to much time into it, I was wondering if there was still much of a "market" for such a thing. I know there was a time when OpenOffice was considered a huge bloated mess, but increases is computing power and clean up of the code base, I don't see those charges as much anymore. Has Open/LibreOffice come far enough that it doesn't need a light weight replacement, or has everyone just learned to live with it?

Reddit: Bash Variables Byte-Size?

Tuesday 22nd of July 2014 12:49:03 PM

Hello all together.

I was wondering on how much size in bit is an integer shell variable big? Is it 32 bit? I could imagine that you can't say it specificly, because bash is not like c or fortran?This is the code for my iteration, where a is full of ones and b is full of zeroes.

for (( i=0 ; i < max ; i++ )); do a[i] = b[i] done

I wanted to know how many bits are tranfered per iteration?

Thanks for your help!
