Parental Controls in Ubuntu - per user
I would like to set up parental controls on Ubuntu for a friend of mine. I want it so that the child user has the controls set, but the parent user is not restricted. To be clear, they are sharing one computer, so a router based solution won't help. And I would like a set of step by step instructio…
How to know what hardware works well with linux?
It's not hard to find desktops that work well with Linux. However it is much harder to know which laptops will work without fault on say a Debian or Red Hat system. I recently ran into an issue with Intel GMA hardware on a Dell D420, after being reassured by most forums that it had no hardware issu…

How can I make Windows Paint save by default as JPEG format?
Every time I want to save an image I've pasted into the Paint application, it chooses a BMP/DIB format (which is the worst for saving things from the clipboard).

Convert a Windows VM to physical partition
I have a VMWare virtual machine running Windows as a guest which I want to convert to a physical partition. The idea is to add it to the GRUB boot menu, and be able to boot it. Is this possible? If so, how? EDIT: I tried using Acronis True Image to duplicate the VM (a Windows 7 guest) to a partitio…
is there a way to split a single browser's window/tab into 2 viewing areas?
I have to frequently visit a webpage that contains a table with thousands of lines. The first row contains the names of the columns. Many of the columns are numerical values. Once you scroll/page down, the first line is gone, and with it the headers. Is there a way to horizontally split a Firefox/E…
How fast is each core in a dual-core processor?
My Macbook has a 2.4 GHz dual core processor. Because it has two separate cores, that means it can execute two functions at once, right? So does that mean each core is approx. 1.2GHz each (for a combined 2.4 GHz) or are they actually 2.4 GHz each, and therefore is effectively running at 4.8 GHz? Du…

Is it possible to have a Google Chrome shortcut use a different user agent than an existing Chrome window?
I am specifying a custom user agent in Google Chrome in order to access a legacy web site on my company's intranet (the site is needlessly requiring IE).

Laptop wakes up when I unplug/power off any usb devices
I am wondering if there is a way to change this functonality in windows - everytime an external usb device powers off or if I unplug it, my laptop wakes up from sleep, which is really annoying. This is on Windows XP. It can be a disk, a mouse,... Type doesn't seem to matter.
How to reset/delete my glassfish password?
I'm trying to install GlassFish v2 on my Macintosh. The installation instructions say that it should prompt for an admin password, but it doesn't, and now I can't log into the admin console on localhost:4848.

Returning from Dual-boot to just Windows
I installed Ubuntu sometime back along side Vista, but later found that I rarely (if ever) use Ubuntu. How easy is it to return my computer to its initial state of having only one OS, and freeing up the hard-drive space used by the Ubuntu install?
