Is it possible to prevent a specific program (i.e. rhythmbox and its dependencies) from ever swapping to disk?I'm asking because I have a problem when a music player hiccups whenever Chromium hogs too much memory. Is there a way to work around this? This isn't a problem in Windows anymore so presumably there is a way.

Actually I'm not sure that it's swapping like mad: I've done more testing and it looks like there may some interference causing the noise that may be correlating with network usage. I'm accessing a MacMini (with MacOS X 10.4) from my Linux machine using VNC. My Linux machine has 4 GB of ram and I run a lot of various apps on it and I've got no issue at all. It's all snappy and don't hear the hard disk swapping/read/writing too often. Now with VNC, the hard disk is swapping like mad. When I'm moving things on the OS X desktop. So I was thinking of creating a ramdisk and forcing the temp VNC files to go into that ramdisk but the problem is I can't find any temp files.
I've attempted to do that:
#!/bin/bash
while [ true ]
do
lsof | grep vnc
done
The VNC version I'm using is this one:
$ vncviewer -version

No matter how much data is coming from the Mac, there should be plenty of memory (4 GB of ram) so there's really no reason to swap like crazy.
I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

View 2 Replies View RelatedI've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.
The button identifies as
Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.
I'd like to know if there's either
a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.

echo 0 >/selinux/enforce
I type that each time before I launch maya. If I don't it wont start.
Not sure why. Essentially it makes it so I need to be su to run maya.
If I was setting up the workstation to be used by others as well how would I disable SELinux just for starting Maya but nothing else? Or how to do I tell SELinux maya is ok for regular users to run?

I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:
1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.

View 4 Replies View RelatedAnyone know how to launch a program from CLI (command line) to a specific viewport? I start programs all the time from the CLI and there are times when I'm in "typing demon" mode and don't want to touch the mouse. Being able to launch a program to a certain viewport (Compiz, w. effects) would be really helpful at times.
I'm familiar with wmctrl and i can use the -a and -c options to switch to and close windows fine. I only have 1 desktop (9 viewports, though), and wmctrl's support for viewport seems limited at best. Ideally, I'd like to launch a program to a specific viewport, but just being able to move an existing one to a specific viewport would work, too.
Please note: I'm talking about moving apps to viewports AD HOC or DYNAMICALLY, not in a fixed way like I believe devilspie and such (and Compiz' Place plugin). Depending on my task, I need to quickly launch several apps to different viewports, and this VARIES for me a lot. ubuntu 10.04 lts / gnome / compiz w. full effects

Is there a way to bind specific programs to specific network devices (not IPs, since I have dynamic IPs)?
For example, I wish for irssi to route through eth0 and w3m to route through eth1. Keep in mind these devices have dynamic IPs, so I cannot attached them to an IP.
The solution cannot be accomplished through route since route pivots on IPs not devices.

I'm having here at home one quite addicted Farmville & similar game player which I would like to somewhat control in at least late night/early morning hours, Was browsing a while around for a program which could be used as a webpage blocker for several hours (predefined time), but all I came up was either scripts which I don't understand (I myself can be counted as a newbie in Linux stuff) and don't want to risk blindly or just user account time manager (timekpr).
I found a great solution in my case for MacOS users called SelfControl, but as you can guess ... there's no Linux native client for that. So, my question is - is there any easy and understandable way to block specific webpages for a predefined time period (let's say, every morning from 03:00CET - 08:00CET)?
OS: Ubuntu 9.10 Computer knowledge of the farmer: Getting on Farmville and/or playing Gnome's Mahjongg is pretty much all.
I have nine barcode scanners, each of whose input I want to send to a separate instantiation of a program I wrote. Each device shows up as /dev/hidraw_ (I'm using Ubuntu 10.4). The problem is that they all act as simple keyboard input, and I can't seem to redirect the output from one to a specific instance of my program. I've tried something like cat /dev/hidraw5 > ./myapp, and that doesn't work. I've tried actually opening the device in my program using open("/dev/hidraw5"), and it returns success, but subsequent reads don't do anything, and the scanner output is just printed to the console.

View 9 Replies View RelatedI currently have Ubuntu installed onto my laptop, on a single drive partitioned into /root /home /swap. I now have an additional spare HD that I was thinking of installing Win XP onto. So If I needed to use XP for a specific program then I could just swap out the HDs instead of having a Dual Boot system on one drive. confirm that by swapping out the HDs this will not affect the Grub Boot Loader and I will be safe to do this without screwing up my Ubuntu, as if it will screw it up I will just stick with Ubuntu on my Laptop and forget about XP.
