When I went for my undergrad CS degree I dropped just over 3k on a 300 mhz PII Dell with a 17 inch trinitron display (this was when Dells were actually pretty nice). 2 years later I replaced it with a overclocked celeron (300 at 550 or something like that)
oops. my less than sign got chopped off. that should have said (small clusters less than or equal to 32 nodes managed by a researcher that "just wants it to work")
problem is, they haven't released new XServe hardware in quite some time, and it isn't as cheap as they claim... and there were bugs that had to be worked on on some of the large installations. There are a lot of small apple clusters out there, which is where they really excel (small clusters (someone who built one of the largest apple clusters 2 years ago)
Interesting that she is allowed to keep a rodent pet when she works in a laboratory, even though the rodent originally came from the lab...I work at a genetics research laboratory, and I'm not allowed to keep mice, rats, guinepigs, or hampsters as a pet at home, or keep any animal as a pet that eats any of the forementioned rodents as its normal food (cats are okay, even though they might occasionally catch mice).
The fear is that someone could introduce a parasite, virus, or bacterial infection into one of the mouse colonies, which would be devistating to our research (http://www.jax.org/research/research_areas.html), and our mouse business (http://jaxmice.jax.org/index.html). I don't handle the lab mice, or even come in close proximity of the mice on a regular basis since I'm a software engineer and this restriction still applies to me.
I've met this researcher (we both work at the same lab), and he thinks that the genes that cause type 1 diabetes (an autoimmune disorder - the immune system attacks the pancreas) were benneficial at some point. They probably provided a fast response to certain diseases, but in ultra clean environments they end up turning on the pancreas.
More evidence to support this idea was inadvertently discovered when a epidemic broke out in a German laboratory mice facility. All the mice died except for a strain that has the gene for type one diabetes, and while the epidemic was active in the mouse colony none of the mice were diabetic. As soon as the epidemic was stopped, the mice became diabetic again.
Since this gene doesn't have to be inhereted from both parents to be expressed, you would expect it to be removed through natural selection, since without insulin it kills before normal reproductive years. This suggests that it has a bennefit. He suggested that it is probably good to let your children play in the dirt.
people are presuming they didn't release the latest darwin x86 kernel (xnu) source because they don't want hackers to circumvent the DRM in OS X by replacing the apple supplied kernel with a custom kernel...
why not put the DRM in something that is proprietary like Aqua?
I have a titanium wedding wring and watch. I love them because they are so light. But if this technology works maybe you really will find them in gumball machiness.
natural selection tends to select out diseases that kill before child bearing age. That's why there are so many age-relaited diseases, but terminal diseases are much less common in children. Some diseases that typically emerge before child bearnng age are still around because at one time the genes that cause them may have had a bennefit (type 1 diebeties is fatal without insulin, which is yet the diesease has not been selected out). Some medical technology might be doing what you describe (for example, in utero surgery on a fetus)
there is no national sales tax in the US. Just state (in most states) and local (occasionally) (for example, some counties add something like.5% to the sales tax amount to finance sports stadiums)
Some things are not taxed, like most unprepared food.
It would be even better if they ported them into the Xnu kernel. OS X uses the Xnu kernel, which contains Mach (3.0 I think) code and Free BSD code (these are fused into a monolithic kernel). OS X does not use the Mach Microkernel (but it borrows a lot of code from Mach).
the kernel is open source, a few other components are open source, but I wouldn't call the OS itself open source, since OS X has a lot of closed source proprietary technology
I had to study about 40 hours per week for several weeks for my graduate level theoretical computer science course, same with my graduate algorithms course. That is on top of the nearly full time job it was to complete the homework assignments throughout the semester and the examinations. This was at a relatively small CS department in a smaller (11,500 student) New England state school (UMaine).
I felt a real sense of accomplishment when I wasn't one of the students that failed the course (B- the lowest acceptable grade!). Iit was interesting that in a small class that was approximately 50% students from india and china, and 50% in-state students, most of the students that passed were the 'locals'.
I write lots of code on my OS X machine that is eventually deployed on a Linux cluster. If you write good code you won't have a problem. I have worked on some code that has had a OS specific module for each OS it has been ported to (90%+ of the code is shared, but there is a set of OS specific routines that interface tightly with the kernel. for example, these are a mix of Mach/BSD system calls for OS X)
I have a M.S. in computer science. I've worked on avanced research funded by the US Army, NIH, and NSF. I participated in research that was used to justify the worlds largest Apple cluster, deployed at another subcontractor's facility.
I consider myself primarily a Mac user, even though I typically use Linux, OS X, and Windows every day. I do the vast majority of my work on my Apple laptop, and it is the platform I feel most comfortable with.
The interesting thing is I've only been a Mac user since the summer of 2004. At my last job we purchased a large XServe G5 cluster (256 nodes), which at the time was probably the 3rd largest Apple cluster in a university. I used a Linux workstation at this point, and I was having doubts about running OS X on a cluster. I flew out to the WWDC while the ink was still drying on the PO. I was impressed with the developers tools I saw at WWDC, and with the whole OS experience. I ordered a iMac G5 for my desk the very day they were available for sale. We had to work at porting some applications to OS X, and there were a few issues with being one of the earliest large HPC clusters (especially one that ran large MPI applications over Ethernet - lots of early Mac clusters ran embarassingly parallel stuff, or infinniband line VT). I took a new job where I spend a good chunk of time writing scietific sofware for Linux based clusters - I insisted my employeer provide me with a Mac (we have about 1,200 employees and run about 40% Mac desktops, but no one in my group had a Mac).
I pay a state sales tax on the 99 cent track (it still only comes out to something around $1.04), but your VAT that is included in your price, is more than 5%).

microsoft would be the ferengi, obviously

I work at a genetics research lab with about 1200 employees and there are about 500 macs on campus.
you can make $20 last an hour at the pub? :) I guess that isn't too far off. Don't try to make $20 last an hour at club supersexe in Montreal though!
