Is there an obvious way of shifting numbers in the gcalc-tool using an operator, such as << or >>
Am I missing an obvious shortcut?
Say I want to simply perform (1<<20), how can I do that without the need to shift by 15 and then by 5 using the drop-down buttons?

Alternatively, is there a good hex/binary calculator that you would suggest specifically oriented at hex/binary operations?

Thanks!

Question: where to install the boot loader?

I have a system with 2 HDs, a 400GB and a 160GB.
My Ubuntu installation is on my 400GB HD and currently I have Windows on my 160GB. I'd like to install another clean linux distro (Mint) on my 160GB (i.e. remove Windows), but I'm confused as to where the boot loader goes. Obviously I don't want it to mess up my Ubuntu installation. At the installation window I'm given the following:

/dev/sda
  /dev/sda1 ext4
  /dev/sda6 swap
  /dev/sda5 swap
/dev/sdb
  /dev/sdb1 ntfs

My question is, I have several options for boot loader installation . So where should I put it? Currently my system boots up and grub loads and gives me to option to choose between ubuntu (default) and optional windows.

My choices are

/dev/sda ATA ST.... (400.1GB)
/dev/sda1 Ubuntu
/dev/sdb ATA WDC.... (160.0GB)
/dev/sdb1 Windows 7 (loader)

What is the difference anyways? could anyone link where this is explained or explain it? Thank you all!

EDIT To be specific, I wanted windows completely gone. Just two Linux distros on separate HDs.

I have a compute and storage node. The home directory is shared via NFS. I'm having a problem with the IO when logged from the compute node. It runs incredibly slow. For example a "$wget" or "$svn co" will take several orders of magnitude from the compute node than from the storage node or a "$make" due to creating the files/installing will run slow. Presumably this is due to the IO writing from the compute to the storage node. I've run several tests to convince myself that it is indeed the IO. Both nodes are connected through a gigabit switch and it's a straightforward install.

I'm at a loss on how to troubleshoot this because I'm very new to NFS setup etc. Any advice on how to even start trouble-shooting this will be greatly appreciated.

Thanks!

I upgraded to oneiric ocelot, running awesome wm. Everything works, more or less, fine but one thing I've noticed is that now my menu fonts and my menu symbols are larger than I'd like them to be.

I used to set them in font settings, but now (for one I don't even know where font settings are anymore, I tried gnome-tweak-tool) the font-settings are gone? Surely I'm missing something.

My prime example is the program evince whose symbols are ginormous.

Any hints how to tweak it?
