Software :: Alias Make To Automatically Use Multiple Cores?
Jan 27, 2010
Newbie question here. I just realized that I can tell make to use multiple cores to compile by doing PHP Code:makewhich is just awesome on a quad core with hyperthreading (I just compiled 2.6.33-rc5 in under 5 minutes!) I know aliases are possible, though I've never had much need. What I would like to know now, is if it would be safe to alias make to mean PHP Code:so that by default I use 6 of the procesors when building or if there would be occasions that compiling on multiple processors would be a bad thing

When I was using Virtual Box in Windows 7, I could choose how many CPU cores to assign to the guest OS. Now I'm using Linux, and when I installed Virtual Box, I couldn't find that option. System Monitor shows that when the VM is busy only one CPU core goes to 100% while the rest are near 0%. How can I make Virtual Box in Linux use multiple CPU cores?

Whenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?

Many commands in Mathematica 8 (Integrate, Simplify, etc.) seem to only be using a single core on my system. Is there any way I can change the affinity so that it utilizes all cores for computations?

I want an alias to move ~/.sportstracker to ~/Documents/Software/SportsTracker_4.1.1 and then zip it and name the zip file like this SportsTrackerBackup_yyyy-mm-dd (example: SportsTrackerBackup_2010-03-08)Note: I don't mind how the archive is compressed, 7z, rar, zip, tar, etc. Although the higher the compression the better

I've been tasked with setting up a wall board display monitor for our monitoring applications and it's got to look good! I was hoping to use opensuse 11.4 & the KDE desktop effect of the cube and I'm trying to find a way to make the screens rotate in a timed manner.
Is this possible and if not can anyone suggest a good way to switch between multiple displays automatically?

I have a laptop that I use in three environments with different monitor setups.
1) At work, I have a 1280x1024 second monitor.
2) At home, I have a 1920x1080 second monitor.
3) In meetings and other places I have no second monitor.
Whenever I switch between these setups, which is at least several times each day, I have to manually change the monitor configuration. I use the nvidia-settings tools.
Granted, it only takes a few seconds. Is there a way to make the system smart enough to automatically detect when a monitor is added or removed, know *which* monitor is attached, and reconfigure the resolution and monitor layouts the way I want them?

I'm running Ubuntu Server 9.10. I have two external USB HDDs. I use them each for different backup reasons. So certain data gets stored on one HDD, and different information gets stored on the other HDD.
I want to make a script that can look at the external HDD can determine which HDD it is, so that it can copy the proper information to it. Is there a way for Linux to determine this? Like if I see one HDD as /dev/sdc1, then unplug it and plug in the other HDD, should Linux see it as /dev/sdd1 or will it be /dev/sdc1?
I don't quite understand how it determines the /dev/sdxx values that it assigns to drives.

I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent.
One told me to add "slitaz home=usb" to the syslinux.cfg file like this:
append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb
but it didn't work for me.
http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically.
custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008)
does anyone know the best way to make the USB automatically persistent?

I want to make g++ find a bunch of header files in a very specific folder, that is not in any path without having to type out the -I command over and over each time I use a new command. any idea to make it automatically look for the headers in that folder. (please don't respond "move them to another folder where it already looks").

So my girlfriend came back from a holiday and it results that she somehow ( dont ask me how) wiped out vista from her hd pavillion laptop. There`s nothing there, the pc doesn't have a guarantee anymore so I thought, what the heck, I could install an ubuntu 10.4 there. It's a nice machine so it should run nicely.
I made her try ubuntu on my laptop and she likes it so she gave me a green light to do it. So how should I go about it? boot the live cd and when I get to the partition part just tell the installer to overwrite the whole c drive and make the partition automatically? I'm kind of a noob so I wouldnt want to mess things up more than what they are.

I have a lenovo thinkpad laptop, and it has both touch-pad (standard build in laptop mouse) and touch-point (in the middle of the keyboard) mouse options.
I almost invariably use the touch-point and the accompanied scroller and key-buttons.
HOWEVER, for the scroller to be recognized by ubuntu you must run two scripts as follows:
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 8 1
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 8 2
Restarting the computer resets these settings, and you must re-run them each time you start up ubuntu.
I am looking to write a script that will automatically run itself (which will execute the above commands), or to permanently change these settings so that it will not be necessary to run them at each start-up.
Thanks in advance, and if there is another thread on these forums that I should move to (or even just another thread that would be a more likely place to get a response). This seemed like the best forum (one which can certainly hold this post without violating any rules), but I may have missed something.

I am trying to make a script to automatically run aircrack-ng.
1. One part of the program is an ongoing action. one that you have to press ctrl+c to cancel, but I need the script to keep running the tasks after it.
2. I need to leave one thing running while running another, so if I could like open a new Terminal tab and run things that would be perfect.
3. I need to keep it all as one script, because the variables need to stay.

I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically.
I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing.

I'm working in Debian, and I've noticed that when I resize my PuTTY window, the console inside isn't resizing to the new dimentions, so things like nano are running at 80xwhatever instead of the more useful 130xsomething that I've offered it.

I used to input Chinese with scim input method, which can be trigered by Ctrl^Space. But this time, I reinstalled ubuntu 10.04, I have to manually start up ibus from System>Preference>ibus firstly before I can triger the input method by Ctrl^Space.
This is not over, the key problem is there are several dialogues to click "ok" with before I can really use the scim.
How can I make this ibus startup automatically and quitely?
I tried put command "ibus -setup" into my .profile, it does start up the ibus automatically every time when I login, but the dialogues still bothering me.

I have checked Yast2's runlevel services option and dansguardian is enabled to 'Yes'. But when i check with 'service dansguardian status' it reports 'unused'.If i start dansguardian by hand, things work perfectly fine.I am in a desperate situation since there are 4 other computers which are dependent on this setup to work correctly

I have switched to openbox from Gnome and would now like to stop using Metacity altogether. When I was using metacity I had both a control theme (e.g. gtk theme) and fonts set up how I liked them in gnome-appearance-proporties. When Openbox starts, it gets my window borders up properly (ofc.) but fails to render my fonts properly and uses the wrong gtk theme. I can't find anywhere to specify which gtk theme to use or what method to render my text with. After Openbox is finished doing it's thing, and I run gnome-apperance-properties manually, it will automatically set everything to it's proper value, but I don't want to have to do this as it takes several seconds to preform and I'd rather not have it jury rigged like this.
