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 Why do my OSes only recognize 3 GiB of RAM?
@JamesTheAwesomeDude Does it work if you replace the 2GB sticks with 4GB sticks, does memtest work then with more than 4GB? Maybe it's actually the RAM slots on your motherboard that are dead, not the sticks themsleves.

comment How would I go about hiding my country for HTTP browsing?
Ask a friend from another country to download it for you, perhaps? Rent a VPS from another country and use it to proxy? etc..

comment Why are some (all?) files bigger on Mac OS X?
Of course, everyone knows the "standards" weren't designed out of good heart to get the binary prefixes SI-compatible, but because of disk drive industry lobbying. I mean, "kibibyte"? Come on. The metric system shouldn't even apply here, for many reasons. But hey, it's the standard...

comment How can I connect to a WiFi that's 500 metres away?
Or you can use a bunch of repeater relays every 10 meters or so, but this type of "infrastructure" is impossibly high-maintenance. The latency will also suck.

comment Computer restarts after 7 seconds
Yes. Bad RAM, or incorrectly setup RAM (when I was updating my RAM, I got the dual channel slots in the wrong order, the computer hung for about seven seconds before rebooting).

comment Getting a matrix of capacitance data from a touchpad
This is likely done at hardware or firmware level, all the operating system receives is the "cleaned up" touch coordinate.

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.

@Dracs +1 I immediately thought of this video as well.
