Avoid Gentoo emerge steal all your CPU cycles

If you have a Core 2 Duo 2.8 Ghz, or better or any AMD equivalent you will be able to compile Gentoo software and continue to work with your PC almost normally, but if you are working on a Celeron, or any other old PC, you will find your computer really slow, while installing new software on Gentoo.

You can use nice to reduce the priority of emerge/portage and let some available CPU cycles for your normal work while compiling.

To do this, we will edit the /etc/make.conf file with your favorite text editor mine is vim

sudo vim /etc/make.conf

Then, add this line to it

PORTAGE_NICENESS="19"

Here I am using the lowest priority, you may use some higher like 13 or 17.

Once emerge is running you can confirm the niceness it has, with htop

Join us on March 24 for Ada Lovelace Day!

If you know women who are excellent in technology, whether it’s game development, software development, consultants and the like, we hope that you talk about them on Ada Lovelace day. It will happen all throughout the blogosphere on March 24, 2009. Many of you might have signed up for this already but for those who haven’t I hopen you’d join me and make a pledge to write on that day.

Writing about women in technology, especially in the free and open source movement will encourage one other as well as show that hey, even if the thinking that this is a man’s world, women can still excel and be on top of their field. For those who are looking for role models, it will be better because you could know more about these women who have paved the way for better things.

For more details, please check out findingada.com

If you know someone in your community who’s worth writing about, please do so! This will also acknowledge that you appreciate her a lot. It could also bring joy to others.

I hope to read your entries by the 24th!

File shrank by bytes; padding with zeros

I was making a backup today and this message appeared, after .tar.gz the directory

File shrank by 2014298112 bytes; padding with zeros

After googling a little, I found that the problem is not actually a problem it is just a file that has more space that it is really using, so it is reserving space for future use, and this makes sense because I was backing up a VMware virtual machine, and the file that gave me this error, was the virtual disk of that VM.
