Let's not get carried away here. First of all, I don't see any mention of "closed form" in the English version of the article.
Also, there's nothing concrete about what he's actually proved. "A formula". BFD. I can go to Mathworld and bring you back a bucketful.
Finally, if that's his formula on the board behind him in the photo, then it's full of sigmas and doesn't strictly count as closed-form anyway.
(Mind you, I'm sure what he has done is impressive for a 16-year-old. Tip of the hat to ya and all that, but this might be being hyped up a bit by people with other agendas.)
You can put "c:\Documents and Settings" in another folder name on a different partition but it's tricky for non-corporate users. You need to burn a copy of your installation CD with a custom OEMINFO.INI and partition your drive first.
I went to the trouble of doing this for my current Windows box and it works beautifully. Now I can reinstall the OS (on the C partition) to a clean state by dd'ing a tar.gz of it from a Live CD without clobbering my user data, and at the same time my backups are more focussed as I'm not bothering with C partition (think \windows and \program files), which I would be reinstalling from installers (and dd'ing, as above) in the event of a disaster.
TrueCrypt encrypted containers can be formatted as NTFS or FAT file systems. I haven't tried other file systems.
I can add ext3 to the list of filesystems known to work with TrueCrypt, useful for apps such as Nautilus and TightVNC that create files with colons in their name.
Also, although this is slightly off-topic, you can easily store a Linux home directory and mount it in place, i.e. just one big volume in
$ truecrypt -t volume.tc ~
and the full home directory replaces the previously empty directory.
The OP is asking for something similar on Windows but that's much trickier on NTFS and Windows for a variety of reasons - TrueCrypt still doesn't allow mounting at a junction point, and a directory used for this purpose must be empty, and by the time you've logged in, you've already got a lot of files open (e.g. your registry hive).
The critical non-selling point for me with Vista was the blatant market segmentation. Vista Home, Vista Home Premium, Vista Business, Vista Ultimate, Vista IE-free, Vista Lite, Vista Media Center, Vista This, Vista That. The only version you could count on to have the features you needed was Vista Ultimate, the most expensive by far. It was just a con, and I walked away from it because of that.
If Microsoft wants to avoid insulting its users, it should stick to one version, or if its bean-counters say it must, a normal version and a cheapo crippled version.
Assuming you are in the UK, then yes, you would go to jail for doing that. Even forgetting the key is illegal, so deliberately destroying it would probably get you an increased sentence.
No, genuinely forgetting a key is legal, but you have to convince the court that you really forgot it and aren't just saying so. (Could be tricky...)
