Can I install Windows OS (Windows 7) on a removable USB hard drive?
I wanted to take a sneak peek at Windows 7 so I thought of installing it. I have Windows Vista on my laptop which came pre-installed with it. I didn't want to mess with it. So I created a partition (20 GB) in my USB external hard disk and tried to install Windows 7 on that partition. But when I boo…
Can I use something like the SSD TRIM command on a SD card?
SSD flash hard drives have started to support TRIM in order to avoid the slowdown that occurs after a while. How do I do something similar on a SD card ? Like reformating the SD card, but at a lower-level to avoid the automatic wear-leveling.
Does storage capacity affect hard drive performance?
I read somewhere that smaller (in terms of disk space) hard drives are faster than equivalent but bigger hard drives. How true is this? In other words, say I have two hard drives. Both are of the exact same brand and specs, but one is an 80GB while the other is 500GB. Which would be faster? Or does…
Is there an optimal setting for the number of CPU cores exposed to a VM?
VirtualBox, and possibly other VM software, allows the user to specify the number of CPUs exposed to the VM. In my particular case, I have a dual core CPU, with Windows 7 64-bit running natively, and Ubuntu 9.04 64-bit as the VM. The help file suggests not setting this above the number of physical …
Finding what's using all the space in *nix
Which sequence of commands will tell me which files are the largest starting from a particular directory, including all sub directories? I want to know where all the space went. Preferably just with regular unix'y commands. If possible, try to keep it compatible with Sun OS 5.10 (perhaps in additio…
How do I combine stdout and stderr for different shells?
I know the answer for some shells, e.g. with you can: How do you achieve the same for other shells (bash, ksh, tcsh, powershell, etc)?
Is there a free (as in money) version of Redhat linux?
I've not dabbled with Linux for a while, but I need to, I am slightly outraged RedHat Linux is not free... or am I being dumb? Is there a free version available? If not what are the best alternatives. (The client wants RedHat).
Paint.NET equivalent for Linux?
On Windows, my favorite image editor is Paint.NET. However, on Linux, GIMP is as unfriendly as photoshop despite having less features. (i.e. It takes ages to load, their's far too much stuff). Most of my image editing is simple things where Photoshop or GIMP would be overkill. Paint.NET does not ru…
What is the keystroke to quickly change a file's name in Windows?
I've seen friends quickly hit a key on the left side of the keyboard and then change the name of a file they had selected. What is the keystroke to do this?
How to sync GreaseMonkey scripts between computers?
I have some great greasemonkey scripts for FireFox and would ideally have a way to sync them between computers. To some degree, it would even be nice to be able to deploy the scripts to PC's across a network at the office. How can I sync these between workstations?
How to make explorer in Vista remember a folder's view?
For no apparent rhyme or reason Vista will decide to show a folder that was previously in details view to start showing thumbnails. I go to the folder and right-click, Customize, and set it the template to "All Items", and "Also apply this template to all sub-folders", but it some point it will aga…
Deleting files in Windows XP extremely slow
When I delete even the smallest of files on windows xp the operation takes 3-10 minutes to complete. I have read this can happen when the recycle bin has alot of items in it, and XP has to iterate through all the files. So I set the space usage to 1%, but even this does not help, the only thing tha…
Windows Domain Authentication with Firefox
We have many internal web sites on our domain: a.blah.com b.bhah.com c.blah.com IE authenticates automatically using the currently signed in domain user but fire fox pops up a login box, sometimes multiple times per page load if assets on different internal sites are referenced. I've tried modifyin…
On Mac OS X how can I monitor what is using my internet connection?
I've got a relatively limited broadband connection (I live miles from the nearest exchange) and from time to time net access (but nothing else) slows to a near crawl. I know from a bit of monitoring software that the connection is being fairly heavily used which would explain it but I don't know wh…
Does Ethernet over Power Lines work well for home networking?
I am considering putting a computer in my garage (geek alert) and my wireless signal is simply to weak to get through all of the concrete, steel, etc. I've seen products at Fry's for Ethernet over power lines, but have not tried it. Is this a good solution for home use? http://www.netgear.com/Produ…
Delete space-expanded "tab" in Vim with one keystroke?
I edit Python code with Vim. With the tab key I get four spaces inserted for indentation. How can I delete those spaces with one "Backspace"(?) stroke - instead of four? There has to be some "set" option for that... Here is my .vimrc:
Tool to determine what has locked a file
Every once in a while when I try to remove a file I have been working with, Windows tells me I cannot remove it, because some application is still using it. Sometimes it's just my own stupidity, and closing the app I was working with releases the file, but sometimes I cannot for the life of me imag…

Is there a way to start vim in read only mode
I use /bin/view as it is a safe way to view text files and not have accidental changes persist once I am finished. /bin/view seams to be lack features that normal vim has.
