Ok I went and read the page. Why do I get the feeling that your Swedish

Mine is terrible. But I read the page too. Are you trying to troll?
There's not enough on that page for me to feel that they've been given
any kind of detailed instructions. I see the formatting instructions for what
they have to write ... including that it must be ORIGINAL (?? or is
this that original sources must be referenced?). Then there are suggested
titles and refs. Then examination dates.

My partner and I run a SuSE linux based cybercafe which we set up ourselves
in West London, UK. Our url www.rainbowcyber.co.uk/ might be worth a look
around.
We configured each terminal with three different user levels, the lowest of
these being for
the user cybernaut with password coffeeshop. For this user we set up a twm
(tiny window manager) which has a basically just a clock and a netscape.
Once you have configged the various user levels, under SuSE Linux, (our
chosen distribution) you can switch into graphical log-in mode and give cafe
visitors that login and p/w for their session.
When you boot up your systems each day, it will come up straight to the
log-in prompt and you can either start the terminals manually, or let
visitors log in themselves. You could set up a higher level access (say to
KDE) under another username/password for trusted users in the same manner if
you didn't want to create an account for each user.
You need to look into the skel (userlevel template) files for more info on
this.

It says:
"Uppsatsen ska vara v�lskriven (korrekta meningar). Ska ej vara
en d�lig �vers�ttning av ett originalverk."
Which means that the text should be well-written, and not just a bad
translation of the original (source-)text (i.e. transcript from a
book, or something like that).
"Uppsatsen ska ha korrekta k�llreferenser angivna."
Further must they note all used sources of information.
> Where's this instruction to get people on the net to do their research for

"Underlag till uppsatsen finner du p� biblioteket, n�tet eller

Which means they can use information found at the library, the
Internet or anywhere else.
Asking on the USENET for references to homepages (links) and
documents, seems a good way to find valuable information.
> And what is a f�rdjupningsuppgifter anyway!
It means the assignment subject they will become absorbed in. In other
words: the title of their report.

Well, from their questions it seems they have been thinking on their
own. Otherwise, how could they ask such detailed questions ?!?

Well, I haven't followed the thread... but if it's a very specific
question they're asking, after having thought a while - I think it's
okay. Asking question when you're stuck or having trouble
understanding something is okay - as long as you're not asking for
solutions to "the whole thing".

Yep.
n�t = net, n�tet = the net
n�gon = some
annanstans = other place

Well, it's hard for me too ;-) Even though Danish and Swedish
are quite alike - they're quite different too ;-)

Eh? Their questions didn't seem detailed to me. Rather what somebody
who had read the first three lines of a book would ask, if they
couldn't make head or tail of the following paragraphs ...
1) How does the three-level page table work? Is it hierarchic in some way?
2) What does the bitmap dealing with free blocks of pages in the free_area
array tell, how many blocks of n pages currently free?
3) How do the memory operations nopage() and swapin() work? When are they
used?

Yes, agreed. The questions do look just sufficiently detailed to me now
to indicate they have some thought behind them. But (1) in particular
just needs "read a book" as the answer. Mmm ... (3) is dealt with
specifically by my copy of Rubin (and no, I didn't know offhand, but it
seems that nopage() has to return the physical address of a page in a
virtual memory area).

Aha. Trailing articles.
: n�gon = some
German "einige".
: annanstans = other place
understandable to both saxon and modern german speakers.

Is there a way to get more precise results than with clock? Something
like Solaris' gethrvtime(3C)?

typedef unsigned long long u64;
inline u64 rdtsc(void) {
u64 clock;
__asm__ __volatile__("rdtsc" : "=A" (clock));
return clock;

note that any, even trivial, web search would have shown this.

ASK for it from people! That's just saying that they can read it up
in their dad's books, but they can't ask their dad for the answer. It's the
normal proscription, and it's precisely the reason the netiquette FAQ
puts forward for not answering students assignment questions.

I don't see any good candidate. It must be "n�tet".
