How Does One Free Disk Space
location: linuxquestions.com - date: December 15, 2009
I did a df and found out that my netbook (Asus) only has 858MB of free space. Files I had downloaded for Citrix were taking up a great deal of space so I ran rm to remove them. Running ls after the rm showed them no longer displaying but another df shows no change in available disk space.
Must I run a command to free the space and return it to the file system?
Running Xandros and KDE on a netbook (Asus EeePC 900) with only .5 GB RAM and 4GB of HD space.
TIA
How does one add keyboard languages and switch between them in Linux Mint 16?

I've added languages in Language Support but I do not see the language icon in the panel tray, nor can I switch between languages.
How does one reboot from an ash shell?
location: linuxexchange.com - date: January 1, 1970
This may sound stupid, but how does one reboot from an ash shell? I have an Ubuntu system that is currently bricked for some reason (not pertinent for this question), which means I boot into a BusyBox ash shell. But the exit command does squat, and reset is irrelevant. There must be a better way to reboot than the power button, right?
How does one tell uboot to tell the Linux kernel which runlevel to boot to?

I would like to order u-boot to enter a specific runlevel lower than the one the system boots to. How does one accomplish this?
Thank you.
How does one add a browser protocol for Windows, Linux, and OS X?
location: linuxexchange.com - date: January 1, 1970
I'm working on creating a cross-platform background program to interact with a site of my creation.
I'm familiar with how Steam does this using the steam:// protocol, and it does so on all three of its target platforms: Windows, OS X, and Linux.
I'm wanting to do the same, but can find almost no resources on the internet about this topic. I know that, if nothing else, it'll require an installer most likely, but I don't know what exactly will be necessary at all. Could I get a pointer in the right direction?
How does one get started with procedural generation?
location: linuxexchange.com - date: January 1, 1970
Procedural generation has been brought into the spotlight recently (by Spore, MMOs, etc), and it seems like an interesting/powerful programming technique.
My questions are these:
Do you know of any mid-sized projects that utilize procedural generation techniques?
What language/class of languages is best for procedural generation?
Can you use procedural generation for "serious" code? (i.e., not a game)
How does one modify an old school NES game? [closed]
location: linuxexchange.com - date: January 1, 1970
I sometimes see modified NES games, and I'd like to try my hand. What tools are used to accomplish this? Is there some magic repository of source code sitting around somewhere that I don't know about? My question is, what is step one to modifying any arbitrary NES game? (If step one is something like 'get your head on straight', then please give me steps one through three.)
Thank you
How does one learn to program game console emulators (hardware knowledge specifically)?
location: linuxexchange.com - date: January 1, 1970
I've asked a similar question before, about how to write an emulator, and when I saw the answers and looked up some open source gameboy emulators, I found that there was much more needed than an intermediate understanding of a "low level" language (i.e. C). What I actually want to know is, what do I need to know about HARDWARE to be able to program such an emulator. I'm closing in on being "pretty good" at Java, but that won't help me a lot. I've started learning C and I've come a long way now, but I'm interested in knowing what I have to study in hardware to be able to write such a console emulator.
The reason I'm asking this question is that I've been searching around the internet for books and sources on emulation, and whenever I come across an emulator tutorial, it's always like "you need a basic understanding of C to be able to follow this tutorial" and when I try to follow it I can't, simply because I don't know what the hell is being programmed. I've never known anything in th
How does one open a network folder from an XFCE desktop?
location: linuxquestions.com - date: May 27, 2009
Hello everyone,
I've using KDE for a my desktop, but I found that my laptop runs a little smoother and cooler when using XFCE. I have never really used XFCE very much, but I am surprised to find that there does not seem to be any desktop (GUI) access to network folder on my home network. Is that correct? Is it necessary to mount them from the command line to access a network folder? I've been trying to figure this one out all afternoon, forums, google, not even XFCE's home page has any infoabout this.
Thanks for any replies.

How does one Capture the Entire Kernel Panic on Boot
location: linuxexchange.com - date: January 1, 1970
Using Buildroot, I'm attempting to make a custom kernel build. After building the image and booting it on a VirtualBox environment, the kernel always panics after the GRUB stage. General summary of what I see:
] CPU: 0 PID: 1 ...
] Hardware name: innotek GmbH ...
] <some registers>
] Call Trace:
] [<c0a1c995>] dump_stack+...
] [<........>] panic+...
] [<........>] do_exit+...
] ...
] Kernel Offset: 0x0 from 0xc0400000 ...
] ---[ end Kernel panic - not syncing: Attempted to kill init! ...
Now, I'm assuming this is only the tail of the message that I want to see, but I have no means to view it (ex: cannot Shift-PageUp). When the panic occurs, the above text is never rendered for a second on the screen.
I first stumbled upon a KernelDebuggingTricks page which states:
Slowing down kernel messages on boot
... [Build] the kernel with the following option enabled:
CONFIG_BOOT_PRINTK_DELAY=y
And boot the machine with the following kernel boot
please wait...
