comment How can I enable onboard graphics AND dedicated card simultaneously?
Just for clarity, this is true for many, but not all motherboards. I have personally run both an AGP card and the onboard to support two monitors on an older system. I have also heard of systems which will permit running the onbaord alongside a PCIe based card, but I have not tested that or researched it extensively.

comment Possible to install linux on an android tablet?
I'm sure you mean a different version of Linux, but just for clarity Android is a Linux variant. I am not aware of a way to install a more traditional Linux distro on something like the Transformer, but I am sure some enterprising people will fix that soon if there isn't one now.

comment Method to add to an encrypted file without providing a password
I don't think that would achieve the entire goal. I would still have to type my decryption password (meant to be secret) into the partially trusted machine (say the ones in the computer lab at the university). With GnuPG and Gravvity's excellent script, I need only reveal a public password that I could freely distribute to everyone in the world.

comment Backing up data in an encrypted way
I know I'm jumping in over a year late, but I suspect Eli and JFW are talking about different things. Many free web hosting services (like geocities when it existed) or targeted providers that make money off of ads (YouTube) did not officially allow storing files that were not linked and using them as backuped violated the TOS. Most paid hosting companies do not care what you use the space for as long as it is legal and would be perfectly fine with using it as a backup for all legal material. I know people with Amazon S3 accounts that use it for backup, for instance.

comment How do I make a file self-destruct?
The hidden volume feature is great, but just to be clear on the "random noise", it is constructed so it cannot be proven to be encrypted data. It is often possible to show that it is statistically likely to be encrypted data. The wikipedia article on truecrypt amoungst others discusses this.

comment Method to add to an encrypted file without providing a password
I should have thought of it, since I have in the past used GnuPG for e-mail, it just didn't occur to me for this purpose. It isn't exactly what I hoped for, but it is good enough for all practical purposes since it lets me encrypt without ever exposing the decryption key or other encrypted contents. Thank you!

comment Method to add to an encrypted file without providing a password
@iglvzx Ironically, while I suspect its impossible digitally, I think you could do it physically. Just look at package drops in a post office. It is easy to deposit a package, but hard to retrieve one without going through the locked door to the area it deposits into. Of course, on a high security safe, adding such an entry may make it less secure than otherwise, but properly designed it could still provide a reasonable amount of security.

comment Method to add to an encrypted file without providing a password
@Nifle I am hoping for a solution since I would like to be able to do this for the reasons I outlined. I'm just admitting right up front that I do not think anyone has one since I think (but don't know) that what I'm asking for is genuinely impossible.

comment File encryption in a bash script without explicity providing password
@b0fh You have a point, but there might be a time when you trust (right or not) that the local computer and its files are secure, but you need to encrypt something that exists on a remote computer. In this case, a password file lets you automate the process.

comment Are Noise-Canceling headphones effective?
If you really want it to be effective, you can have custom made earplugs that are molded to your ear. I have never personally tried them, but I hear the noise protection is excellent. Also, you can wear a pair of ear protectors over some types of in-ear headphones if you really want to block out background noise while listening to whatever you want. But proper ear protectors tend to be somewhat bulky.

comment Hacker sending email from hotmail, changing password doesn't stop it
Very complete explanation. I would point out that 3 is much more likely than 2. Also, this is might be a good time to make sure your browser and or e-mail client are relatively secure. Firefox (with noscript) and Chrome are more secure than IE on the browser side.

comment Create multiple zip files that are not dependent on each other?
Yes, this is technically correct. But as Ravachol explains, you can use scripts to create groups of files to archive (and even do the archiving) and as long as the files weren't huge you could gauruntee each Zip file would come in under 50MB by forcing each group of file to be less than 50MB before compression (or come very close with some guesswork if you are willing to tolerate going slightly over 50 MB in the final archive.)

comment Check email at fixed interval
I am a huge fan of thunderbird and find it much more useful than the GMail interface (which I use when away from my home computer) especially when dealing with multiple accounts.

comment Are USB hard drives really reliable enough to backup to?
There is a huge array of USB drives, so answering that question in general is very hard. You can look up reliability for most individual drives, especially the upper end ones, on the manufactures websites. Also, it will matter to a degree how much you move/toss it around. As a general rule, they are reliable enough that its not an issue for an average end user, but no existing medium is so reliable as to be trusted for a sole backup.

Yeah, I tend to keep upgradin computers rather than replacing wholesale, so I have harddrives die on me from time to time.

comment Online Virtual Enviornments for Old Operating Systems
I have never used it so I am not endorsing it, but cloudshare may do what you want. I'm not sure it will free you from managing it though. Many cloud providers take care of backup and high availabilit for you, but, especially when talking about a VM, you still have to configure and maintain it. In the database world for instance, SQL Azure relieves you of some administrative burdens even as it creates others.

comment Where are Windows 7 Passwords Stored?
@ekaj define crack? If you mean you want to generate every possible 8 digit password, I suspect you could do it in much less than 22 days on a decent desktop. If you mean actually then try those to see which one decrypts your target file, that depends on how long each attempt takes, and that would take much longer. Also, 8 digits is not considered long for a strong password, and the difficult goes up exponentially with each extra character.
