Music players on Linux – the poor mans random song player.

If you have more applications running on your system then your system can handle them then you know what I mean when I say that the Music Players take a lot of CPU. Otherwise harmless, but when you are doing too many things, then lot of times you would feel that probably stopping the Music player might help. But then Linux is all about alternatives. So, there is a command line player called mpg123, which does not use so much CPU. But what about playlist 🙂

unable to browse windows network with samba4

I use Fedora 17 on my work laptop and thus need to connect to windows share sometimes. After I upgraded to Fedora 17 some time, I was unable to browse the windows network. I would get all kind of errors and warnings and tried everything that I knew about Samba to fix the issue. Tried searching through all the forums to figure out what was wrong but nothing helped.

As usual time in couple of days to upgrade to Fedora 17. Release schedule is for 05/22 and so its just around the corner. So, if you are looking at upgrading using yum, then make sure that you visit this page.

There are some changes in latest version that will not allow you to upgrade without executing few commands manually and that page lists them. And if you are too brave and just want the steps and the command then here it is:

uptimed – keep track of your system uptime.

Uptimed is an up time record daemon keeping track of the highest
up times the system ever had.

Uptimed has the ability to inform you of records and milestones

parse the records, which can also easily be used to show your
records on your Web page

Installation :

sudo yum install uptimed

Once installed, you will have to first create the boot id with this command:
