I'm fortunate to have a good job that pays well, but I'm envious of the cheap on-site day care at SAS. I can get non-subsidized child-care through my employer, but it will cost me over $3k/month (mostly post-tax) for two toddlers once my wife goes back to work full-time.
To be fair, Red Hat is capitalizing on the work of Linux developers.
To be even more fair, Red Hat employs many of the prominent Linux developers, and is currently the biggest corporate contributor to the kernel. In addition, they're heavily involved with GCC and gdb, not to mention MANY other GPL projects.
The index is solid. It would seem that one should be able to take this for granted with a technical reference but I've seen some sad exceptions.
I think that Beazley generated the index himself with a Python script. I took an employer-sponsored class from him recently, and he was particularly proud of the new book's index.
At the risk of being modded Offtopic (which I am), You are either trolling for grammer Nazis, or you misapprehended a phrase... I believe you meant to say "For all *intents* and *purposes*" in your signature line, not "For all intensive purposes..."

there was a exclamation mark. 300 factorial, 300 x 299 x 298 x 297x... x 2 x 1.
Incidentally, if anyone wants to calculate that, you'll need to use a float, and probably a double-, or quadruple-precision (YMMV) one at that.
If you're computing an integer-valued function, the result should be an integer. In Python, which uses arbitrary precision integers by default, it's as simple as: >>> import math >>> math.factorial(300) 306057512... [truncated to get past the lameness filter]
I agree. I was only replying to your comment about what developers need. Our desktop machines (for code development on remote servers, email, web browsing, office apps) are quite a bit more modest in their capabilities.
What the hell are your developers doing to require that much horsepower? Thats almost as big of a horse as the live streaming HD video decoder/encoder/remixer we had at my last job. We had exactly one of these machines.
I don't know about the GP poster, but I work in scientific computing, and 24GB RAM is useless to us for anything other than our desktop machines. For our simulations, the necessary RAM is measured in terabytes or (soon) petabytes.
Parallel computing is great for solving NP-Complete problems. If you have enough cores for every possible solution you can have all possible paths process at the same time and compare the results.
That's tough to manage when the number possible paths grows exponentially with respect to the input size.
Complexity classes are typically defined in terms of asymptotic behavior (time, space, etc.) Consider a relatively recent breakthrough in complexity theory:
NP = PCP(O(log n), O(1))
Can you give an interpretation of the PCP theorem that doesn't rely on calculus?
Thanks for telling us that those claims are too complicated for you to read. Please make sure to put that on your resume, because if I was a potential employer looking to hire you for anything even remotely technical, I'd want to know that you give up whenever a discussion gets remotely above the complexity of "M$ sux0rz."
That's not a technical description: it's legalese. I've done my share of technical writing, ranging from scientific journals articles to user and developer documentation, but I'd never be able to get away with producing such incomprehensible gibberish.
"Do colors vary continuously in two dimensions (forming a wheel) or one (forming a line)? Or, wait a minute, we measure colors according to the strength of their red, green, and blue components, so don't they vary continuously in three dimensions? Well, the answer is in there. "
There is a 1-to-1 correspondence between [0,1], R, R^2 and R^3 (R^n), so doesn't really matter which way you want to place the colours. It just happens that we can draw 1 and 2 on a piece of paper.
It's true that R^n and R^m have the same cardinality, but that doesn't make them interchangeable. In particular, when m != n, R^m is not homeomorphic to R^n.
FWIW... In my experience SharePoint is a flexible, feature-rich, capable tool. I was skeptical at first, mostly because I just didn't feel like learning it. But as a Project Manager I haven't found a better tool to replace the services you get from SharePoint.
If you're stuck with it because your company bought it and expects you to use it, then my honest advice is to, man-up, take a training course and learn to use it.
What is the money amount going to punish? They just calculate it into marketing budget.
Exactly. And next time they sit in the conference room discussing a new ad campaign, someone will note "let's not do Option B - last time it cost us $10 mil more than we expected. Options A and C will be much cheaper."
And by the way - the coffee wasn't just hot. It was exceptionally hot; scalding hot. During the court case it was noted that coffee served at home is usually 135 - 140 degrees. McDonald's required it's coffee to be maintained at 185 degrees plus or minus 5 degrees.
That's the proper temperature for hot coffee! Check this out:
The victim suffered 3rd degree burns - from coffee. Burns that are unlikely to come from coffee even at 155 degrees. In addition, McDonald's was aware of the safety involved with their policy and had been aware of it for 10 years with over 700 reports of injuries (including other cases of 3rd degree burns). This wasn't a simple case of getting rich with a frivolous lawsuit - it was clear negligence on McDonald's part. Investigations after the verdict showed local area McDonald's serving coffee at a much safer 158 degrees. Clearly the punitive damages worked.
Yeah, great, now it's harder to get a good cup of hot coffee served AT THE PROPER TEMPERATURE.
OSI was founded by people who were unhappy with the Free Software Foundation and the GPL. OSI Founder Eric S. Raymond recently said that the GPL is no longer needed [osnews.com].
There's a very good reason few people listen to that fruitcake anymore.
If you had read the summary you'd see they work for the OSI and the Linux Foundation. Hardly organizations that are anti-GPL, anti-FOSS or anti-Linux.

When you say accessed, do you mean accessed or accessed quickly?
As far as I know, there's no direct way to share memory across nodes. Of course, strictly speaking any node can access any memory location in the computer using a combination of MPI and local memory access, but that's no longer a simple pointer dereference, and isn't related to the size of a pointer.
Not too long ago (15-20 years, maybe?) 64-bit processors would have been unheard of on the desktop. I see 64-bit being stretched as we put more high-definition video into our datasets. And then we'll have the next "ultra high def" format that will stretch it even more. And then you have a small (in terms of units shipped), but very profitable business in supercomputing. Protein folding and subatomic research folks would probably jump at the chance to rerun their simulations with a higher resolution.
Just to put this into perspective, the forthcoming IBM Sequoia supercomputer will have 1.6 petabytes of RAM, and only a very small fraction of this can be accessed by a single compute node. The total amount of RAM in this machine is still 4 orders of magnitude smaller than what can be addressed with a single 64-bit pointer.
Why isn't anyone picking up on the fact Sohi was possibly working for them illegally? Did the H1B's run out?
You've got to be kidding me. When I was a grad student at Wisconsin, Prof. Sohi was the CS department chair. Don't assume that someone is an "H1B" just because they have a foreign-sounding name.
No sane person wants any kind of ad, targeted or not.
I find the targeted ads on Google searches to be useful. When I'm searching for information on Product X and there's a sponsored link along the lines of "Buy Product X here for $...", I'll often click that link if the stated price is reasonable. Well-targeted non-intrusive ads can be quite helpful for comparison shopping.

Just cause you can smell it doesn't mean you're breathing in anywhere near enough to cause any amount of harm.

If you lead an otherwise healthy life with reasonable amounts of exercise and good food, a couple cheeseburgers every now and then won't hurt you. Smoking will, even in small amounts.
Where's the evidence for that? I don't know about cigarettes, but although the studies I've seen about moderate cigar smokers (<5 per day) show some increased health risks, I've yet to see any evidence that more infrequent smokers (such as myself, <3 cigars per month) face significant health risks. I'm not claiming that infrequent tobacco usage is safe, but I haven't seen any solid science that indicates otherwise.

... Smoking helps me with my anxiety...
The most stressed people I know are smokers! It is such a fallacy that smoking helps with stress.
I think it depends on why one smokes. I enjoy smoking cigars when I have the time to savor one (2-3 times a month, if I'm lucky), and it absolutely helps ease away my stress. I'm not addicted to nicotine, so I smoke only for the pleasure of it.
