I am an undergraduate computer science and mathematics student in New Zealand. My fields of interest are computer graphics, in particular the physics of light transport, and to some extent cryptography, as well as programming and software development in general.

comment Messed up boot scenario, no keyboard
Yes, the backup keyboard worked once for the live CD, and then failed (call me unlucky..), should've clarified that, sorry. Resetting the BIOS, I believe the disk would boot before the hard drive, but I don't actually have a CD/DVD with a live CD on it (it's on a USB stick). I could burn it, though I have no writeable DVD lying around. It's dawn now, but I'll try and find a keyboard somewhere. Thanks for your help nonetheless - the work isn't critical but I did not expect my computer to 'fail' in this frustrating way (morale: you never have enough keyboards)

comment Messed up boot scenario, no keyboard
I can't boot into a Live CD because the boot sequence in the BIOS is SSD (Linux) -> HDD 1 (Windows) -> HDD 2 (not bootable - linux home drive) and I can't change it due to no keyboard.

comment External SSD speed reduced during copying
I suppose most of the small files got copied quickly, accounting for the 15-20% of files you observe, and then the rest of the files, being somewhat larger, took more time to copy. Of course, we'd all want it if we could copy very quickly all the time, but it just doesn't work that way - you don't get to choose the copy speed, all you can do is optimize your file structure for efficient copy. In particular, if you aren't going to use those game files anytime soon, you should archive them in a .tar or .zip file for storage.

comment Why is the display resolution not exactly 16:9 or 4:3?
@moose Which is a horrible choice because the height is not an even number. This breaks a lot of applications, in particular graphics rendering, where many techniques, both software and hardware, implicitly require height in pixels to be a multiple of two.

comment Portable folder encryption software that doesn't require admin rights?
This is kind of an off-topic question, as it's a product request. That said, because what you want usually requires a user-mode filesystem, I'm not sure you'll find a way to do so without admin privileges, at least not with the same flexibility. This could be migrated to SuperUser.. perhaps..

comment Portable folder encryption software that doesn't require admin rights?
When you say "encrypted folder", do you mean an actual folder which only contains encrypted files, or do you mean a virtual folder, like a mounted encrypted archive which you could access transparently?

comment How much does a gigabyte worth of data physically weigh on a hard disk?
Yes, because "I weigh 750 newtons". Technically, you are right, but in popular usage "weight" is almost universally meant to refer to mass.

comment How to download Youtube videos in Google Chrome browser?
@hhh If you can't get extensions for some reason, there should be some software you can get to download youtube videos as a last resort. I've seen literally dozens of "youtube video downloader" variants for Windows, there's bound to be a few for OS X.

comment Measuring how much battery charge a process uses in Windows
I think the network card also takes a bit of power to function, if you're constantly downloading it can't go into low-power state either.

comment Task Manager indicates program is 64-bit?
Nitpick, but there is no such thing as x32. It's x86, and then x86_64 (sometimes x64).

comment Can random data from a wipe or encryption of a full drive result in fake partitions appearing in the MBR?
Statistically, it is possible for random data to just happen to describe a valid partition header, but such an event is inconceivably unlikely. For all intents and purposes, the probability of this occurring is zero.

comment How to 'ping' politely
One ping per minute can hardly be considered flooding by any sane metric. The -f flag probably does something else as commented above.
