No, an open mind in the face of overwhelming fact is willful refusal to pass judgement, not a lack of bias.
You sir, have read too many fortune cookies.
Whenever I see a post beginning with something that sounds so cliche I can never take it seriously. I've tried, its always turned out to be a waste of time.
This is why I left New England despite loving it so much.
High taxes, horrible weather (I grew up in Buffalo, NY so I'm now sick of the snow), bad roads, expensive homes in areas where there's any work.
Now I pay no state income tax. I see no snow. I see green trees for most of the year. I don't have to deal with potholes the size of a small car. I don't have to deal with high home prices (2500-3000 sq ft places for ~250k in good areas).
The people here? They're the same people you see anywhere else... Hell, most of them moved here from somewhere else.
Yeah, they use both HDL coding and EDA (cad-like) tools to design most microprocessors. The designs are too massive to design them by placing each wire manually - they haven't done that for _several_ generations (1980s? - not sure really)
That's not to say there isn't a small army of design engineers at Intel and AMD who work with nothing but schematics - there are. Its just that most of the logic design work is done on the HDL coding level (with either VHDL, IHDL, Verilog, or some other tool). You only start dealing with schematics at a much later stage of development. Until then your designs are constantly changing and its infinitely easy/faster to change a few lines of HDL code than to re-write hundreds/thousands of wires and transistors.
I've worked at both Intel and AMD in the past and in both cases you could take the entire codebase for a processor (HDL, microcode, ROM, etc), compile it with the right HDL compiler and run the entire thing with small test programs as a simulator. Thats how much of the validation/verification work is done before they make the masks.
As for using the old code bases... That's done a lot. There's just too much complexity and too little time for them to re-write every processor from scratch. You also have countless hours invested in making sure previous designs work. If you're only doing small changes it would be hard to justfy building something from scratch since you'll have to do all of that validation work again.
I went to school with a few people in one of the labs working on this and that was the joke they kept using around the lab at first...
I think they even had an austin powers poster in there somewhere.
The x86 micro architecture specifies 8 32-bit integer registers. (some of which are used for stack pointer, etc) In x86-64 this was raised to 16 64-bit registers.
If we were talking address space it would be: 2^64 - 2^32 more virtual addresses
Every additional bit that we tack on doubles the address space. Adding 32 bits double's the possible values 32 separate times.
... or has Harvard just lowered the quality of its graduates by inflating everyone's grades?
The stories about it may be completely bogus but if they are giving out that many A's then something is definately wrong.
It might change in the future but right now Gmail's spam filter is amazing.
Out of curiousity I decided to forward all of my university accounts to Gmail (these accounts get 100+ spam emails a day). Gmail has correctly flagged EVERY single spam message and dropped it into the spam folder and I havent seen any false positives.
As long as I never have to look at it I really don't care what people send me.
"US troops in Iraq were supposed to have a clear superiority in the battlefield..."
I think the someone's forgetting that we rolled over the entire country in about a week.
Living only an hour or two from the volcano the only thought running through my mind is....
Where'd I put the marshmallows! Roasting marshmallows on a lava flow is just too cool to pass up.
The best laptop lock you can use at college is your door lock. Keep the door locked when you're not in it and you won't have a problem. If you're going to leave for a few minutes just lock the thing.
Sure it takes a few extra seconds to get that girl into your bed when you come back but at least then you'll be worrying about her and not your laptop!
This would have been a big deal 20+ years ago but today its rather common.
I'm happy for her but what's so special about it happening at MIT vs. every other time its happened at other institutions?

That Bob Colwell talk really is a good one. It may be about 2 years old but it still holds true for the most part.
If you haven't checked it out you should.
According to Intel presentations...
VIIV rhymes with Five

And yes, I stayed in the US.
I agree 100% but I'm shocked you didn't get lynched for saying that around here.
You'd be surprised how hard it is to find a good canidate for hardware development.

Its a shame when people miss good sarcasm
His new office is a conference room I used to use at AMD's Austin South site. :(
It has no windows
"... surpassed 1.5 million paying customers in China"
.5 Million paying customers :P
1 Million ebay gold farmers
(Before anyone complains... this is not racism)
Different concept.
The x86 micro architecture specifies 8 32-bit integer registers. (some of which are used for stack pointer, etc)
In x86-64 this was raised to 16 64-bit registers.

2^64 - 2^32 more virtual addresses
Every additional bit that we tack on doubles the address space. Adding 32 bits double's the possible values 32 separate times.
One nice thing about x86-64 is that there are more registers for the processor to use when running in x86-64 mode. 2x as many.
More registers -> less register spills -> less memory accesses -> faster execution. (usually)
If you're wondering.. "what is a register?":

I'm posting anonymously because my father works at HP and I have done some work for them and they continue to be a client of my company.
Um, if you want to post anonymously you don't give that much information.
Actually, Intel is a silicon manufacturing company. It sells silicon. It just happens to be in the form of chips :)
Ask someone inside Intel why AMD is only a marginal threat and most of them will start talking about manufacturing quality and capacity.

or just 'crossed 100,000'
:(
Crossed 100,000 what?
Did they bless 100,000 pilgrims?
Did they anger 100,000 people?
Yeah, yeah, -1, offtopic

Cool! Who's handing out the free tin-foil hats?

Yeah yeah, RTFA, I know

yeah, that was a bad joke
