I'm trying to install 32/64 bit ubuntu on my 6GB memory equipped PC. I'm going to use the ubuntu PC mainly for development purposes - Xilinx FPGA development, gcc both for 8086 and ARM software development including Linux kernel compile.

Is it OK to use 64bit ubuntu for these purposes? When I tried to download ubuntu 32bit version is recommended, so I wonder if anything is wrong with 64 bit ubuntu for whatever reason.

Why not use 64-bit Ubuntu?

When I tried to download Ubuntu, I have two options : 32bit and 64bit, and 32bit is recommended. Is there any reason for this?

What setup do I need to use up-arrow to run previous command? With Mac, I can use up-arrow to rerun the command that I just run, but it doesn't seem to work with my bash shell.

I use 8.04 (I can't use the newest distribution because of some compiler version issues).

ADDED

I didn't change anything as it's a fresh install with VMWare Fusion on Mac.

The newest Ubuntu (10.10) has gcc version 4.4.4, but I need 4.2.1 for compilation issues. The library that I'm using requires me to use 4.2.1.

How can I downgrade the gcc to a specific version?

I use Ubuntu on my Mac with VMWare Fusion. I setup share folders.

However, I don't have anything in /mnt/hgfs

I did have the shared directories, but they're not there. What's wrong with this, and how can I link them back again?

I happen to install model sim VHDL simulator on Linux. The manual says it only supports RedHat or Suse, but I just tried to install it on Ubuntu. And, I could install it without any problem.

• Is linux binary universal to all kinds of distribution? I mean, if I make a program on distrubution A, can I be sure it will run on any linux?
• Why most of the commercial program vendor says the program is running on specific distribution? (mostly Redhat and Suse, not ubuntu)

In ubuntu, I can run firefox with the command firefox in Terminal, or click the button in dock or panel.

How does this possible with ubuntu? I googled to find the name launcher, but I don't know exactly how does it work.

• Q1 : How to make launcher? If I make a GUI program, does that mean that I need to create launcher to start by clicking it?
• Q2 : Can I make a launcher for whatever program, even if it's not a GUI program?
• Q3 : How to link a launcher? How can make a link to a launcher in a Desktop to start a program?
• Q4 : The idea of launcher is unique to ubuntu? Or if I have one launcher, can I use it for other distributions?
• Q5 : Why some of the program pops up its icon in Docky (firefox for example), but some of the program doesn't (p4v for example) ?

With Mac, I have istat that shows computer info (memory/cpu/network ...) in real time.

Does Ubuntu have a similar application?

I use ubuntu 10 with VMWare Fusion for Mac OS X. Mac uses Command for what Mac/PC uses Control key.

Can I make the Command sends the Control command in VMware or get the same effect in ubuntu?

I used sudo apt-get install emacs to download emacs. I expected the command-line emacs to start when I ran emacs but instead the GUI emacs started.

How can I download the command-line emacs?

I asked and was answered at this post about opening a GUI explorer from a command line.

How about the other way around? I mean, is there a way to open a terminal from xdg-open or nautilus?

I download emacs with 'sudo apt-get install emacs'. When I run emacs, I see emacs with too big fonts. I don't know why the default setup to have normal font size in emacs. How can I do that?

Inside the terminal, I could use the command 'explorer .' in Win32 or 'open .' in Mac to open GUI explorer/Finder.

What's the equivalent command in Ubuntu?
