You can perform conversions from any number system in the same way. Each position has a value based on it's distance from the . separating the whole portion from the fractional portion (decimal point in decimal). The position just to the left of this point is the 0th position, and this goes up as you move left and down as you move right, so:
1076.235
Position 3: 1
Position 2: 0
Position 1: 7
Position 0: 6
Position -1: 2
Position -2: 3
Position -3: 5
Each position's value is the base of the numbering system raised to the power of this position, so:
1*(x^3) + 0*(x^2) + 7*(x^1) + 6*(x^0) + 2*(x^-1) + 3*(x^-2) + 5*(x^-3)
so let's say this is an octal value:
1*(8^3) + 0*(8^2) + 7*(8^1) + 6*(8^0) + 2*(8^-1) + 3*(8^-2) + 5*(8^-3)
1*512 + 0*64 + 7*8 + 6*1 + 2*(1/8) + 3*(1/64) + 5*(1/512)
512 + 0 + 56 + 6 + 1/4 + 3/64 + 5/512
574 + 128/512 + 24/512 + 5/512
574 + 157/512
~574.306641 base 10 equals (approximately) 1076.235 base 8
Chances are the bases you'll deal with are 2,8,10, and 16. Even base 8 has fallen out of favor, but i guess it's worth working with. If you're doing this by hand, and you're moving between 2,8, and 16 there are some "tricks". Every octet is 3 bits, every hexit is 4 bits. Knowing this you can do conversions from either of these bases to base 2 or back again pretty quickly and easily with grouping. Note that between 2,8, and 16 you can exactly represent anything from one of these bases in one of the others. This isn't so with base 10, so we end up making approximations because converting from one of the other bases to base 10 can give us an irrational number, and some decimal numbers with a fractional part cannot be represented in binary at all, so they have to be estimated.

not without doing a restore and losing the passcode lock... but then they'll know when the passcode is different.

its not officailly a line till someone gets behind you
Good point. And nobody's getting behind me. There's only ONE freaking item in stock. WTF would they just have ONE shipped to them, its pretty funny. Even the manager here is laughing about it. They're telling other's who even call to ask that they're sold out cuz I've already claimed the one here.

That vid card, is that a specific Mac card? Also ram must be installed in equal pairs.
Can't really think of much else. Are you getting a white screen with apple logo at all or just nothing?

how much for the shipping on the PIII board.
also what socket and specs and make/model? Whats the highest, does it have AGP, how many RAM slots.
I think I already claimed it ;)

Permissions should be 744 I guess (all-read-read), maybe 755.
.htaccess files are inherited. Put one in your root directory, and all directories will be 'protected'. :)
You may of course over-write the inherited .htaccess parameters for a given directory with a new .htaccess file. In turn, this new file will cascade down to all sub-directories.
Or you can edit the httpd.conf file. For the DocumentRoot, you will see a <Directory> directive. Simply put -Indexes in the Options tag. Be sure to check throughout the file. The Apache default is to make the DocumentRoot very strict, then loosen the perms later on.
I personally prefer this method over .htaccess files, just for the cleanliness of the web directories. Also, it eliminates any file permission security holes that may pop up.
EDIT: If you choose .htaccess files, do _not_ use 744 or 755. You want these to be 644, maximum.

Awesome!!!
I had BEGGED my boss last year to let me go, and the day he approved it, the conference sold out so I was screwed. This year, different boss and it just wasn't in the budget, so AGAIN I didn't get to go. At least this time around I can get all the sessions and content... Now I just have to find a week to watch them all!
Way to go Apple!

I have run accros many of these in my area. I always send an email asking to meet somewhere so i can check it out. So far i have always gotten an email back about how they are currently out of the country, but they want to do the transaction via some escrow service. I guess i am hoping someday i might get lucky, but probably will never happen.

I am looking to buy "the best" monitor for my gamingmonster, price is not an issue. I dont want something like the apple 30" screen because it hurts my eyes. What is the best gaming monitor around which can be used to watch dvd's aswell?
Thanks.
Thanks.

I'm interested in finding out how early some people will be going to wait outside the Apple store. I've never waited for a release on anything before, so this is all very new to me... haha.
I still remember walking through a mall the day the iPhone was released and just being in awe at the lines and lines of people I saw.

Are you hosting Apache on port 8080? You could just set up a virtual server at *.:80 and any requests to there could be re-directed to the virtual server on *.:8080.
Otherwise I can't think of a way to handle it from something other than the receiving application layer.

I think the name is stupid. But then again I hated the name Macbook when I heard it and thought Apple would never use that name so what do I know? :o

If they haven't been purged at all in over 5 years I'd say 15gb is probably a minimum!

It seems to me that the French generally don't have issues with Lance, but there is a small (yet vocal) minority that is very anti-Lance. I guess the French don't have much tolerance for Texans... ;)
To be honest I'd like to see if Ulrich can win again post-Lance - he was always a great sportsman and his rivalry with Lance (while a bit hyped) was very entertaining to watch.
The French Press HATES Lance.

Hi there,
Just wanted to make a suggestion on thread titles. I may be the only one, but I think that thread titles with repeated question marks (?????) are annoying and unnecessary. It only suggests unnecessary urgency and importance to the thread the poster has written. Therefore I think there should be a rule that states that threads with more than one repeated question mark in the title will be deleted until renamed.
Thanks,
Ams.
