I was once trying to setup a Windows workstation that was reasonably secure. One of the requirements was to prevent removeable media, such as USB Thumb drives, from being used to covertly steal proprietary data. Its been awhile, but disabling this functionality in Windows 2000 was not trivial. After messing with drivers for awhile, a co-worker showed up with super glue! We simply glued the USB ports!
The article explains how having lots of internal ROM in an IC is expensive.
The is absolutely false. I worked on a cellphone product in which the main IC (DSP, MCU, etc) had 4k of internal ROM. The cost of the entire part was less than $15 and remember, this included _all_ of the digital circuitry.
You can easily have more than 512 bytes of internal ROM.
How does VMWare fit into EMC's strategic interests? I'm surprised that Apple didn't buy VMWare when they had the chance because with the move to x86 hardware, having VMWare part of OS/X would be killer.
Right. Getting a 4x5" _color_ sheet of film developed is still $2 a pop. But I am more into taking a few quality shots than dozens of mediocre (thats what my 35mm and Ikonta is for). I also have a 6x7 roll-film holder for my field camera.
But B&W is different. Film can be had for 50 cents per sheet and developing it yourself doesn't require a complete darkroom. Just a light-tight bathroom.
I got my 4x5 enlarger at a garage sale for $75. The rest of my darkroom investment was probably a couple hundred for various things. I wonder if I will get this hobby "out of my system"?! I probably will, but I think my 4x5 gear will still offer a higher price/performance ratio for me even 10 years from now. My hunch is that consumer CMOS imaging chips will not see the same improvements. Noise is becoming a huge issue and the economics of silicon will not make large sensors viable. I have no doubt that high-end sensors will eventually eclipse 4x5" film but these will be priced out of the reach of an amatuer like myself.
That explanation is false. 4x5" Velvia is the same as 35mm Velvia. Even a drum-scan of a 35mm Velvia transparency still captures more detail than an 8 megapixel DSLR (although it is noisier). Some place the detail available in Velvia at 6000 dpi.
Sure, large-format lenses don't quite have the lines/mm that quality 35mm lenses do, but it is not far off.
Simple math: 4x5" = 20 square inches of film
Multiple by a modest 2000dpi scan (20*2000*2000) = 80 million pixels.
Trust me. 4x5" Velvia has PLENTY more detail than 2000 dpi. And at 2000 dpi I am not limited by the lines/mm that the lens is capable of resolving.
An Epson 4990 flatbed scanner will give me over 100 megapixels from a scanned 4x5" large-format negative. Digital will not come near this for quite awhile and it won't come cheaply. This allows me to make a nice 16x20 print at 400dpi.
Of course large-format is very heavy. My pocket shooter is a $16 Zeiss Ikonta folder camera. It folds up to about 1.5" thick and pockets easily. Yet it gives me 6x6cm medium-format negatives. So $4000 Canon dSLR might equal a 6x6 negative, but for $16 I get better price-performance ratio.
Then they should buy VMWare. If your time is worth anything at all, the $200 license fee will be paid for by avoiding the hassle of configuring dual-boot and whatever.
Honestly dual-boot seems to be for tinkerers. Anybody with a need for both operating systems will either purchase more hardware or virtualize it with VMWare. I sure hope that NTFS write support in Linux is at the bottom of the list for new features.
Well, there's always the totally obvious conclusion that Apple is interested in such hardware. And who ever tested hardware with absolutely 0% chance of it appearing in the finished product?
I have. Dev kits often have more memory, extra debugging interfaces, extra peripherals because management hasn't decided on whether to include them, and etc. I've also developed software on dev kits lacking hardware not seen in the final revision. Because if your software development is completely independent of the missing hardware, then the devkit still serves its purpose. In the case of Apple, the trusted module would not effect Adobe's development of Photoshop now would it? These devkits are meant for application writers so that you can have some launch titles.
The shuttle was designed to haul and return huge cargo loads. There is NOTHING else ever designed or built than can safely return an object from space the size of a school bus. This is a remarkable feat.
Now you can certainly argue the merits of the shuttle goals. But the shuttle is still a marvel of engineering.
Nearly all Windows development involves a GUI. This is usually done with an event-driven API. On the other hand, many Unix geeks probably never program in the event-driven paradigm. And more Unix programs are written for consoles
Unix is process-centric. Windows is thread-centric. This is also an artifact of GUI programming. For example the GUI should never stall by processing a request. Instead it should fork off a thread
Unix has the philosophy of making small, indepedent programs that may communicate via simple means like stdin/stdout. How often to you make small console programs in Windows? Windows programs communicate with one another via the Windows message-passing pump
People still often use plain ole' C in Unix. Nearly every Windows developer I know uses at least C++ if not C# or VB.
Unix programmers are more likely to use standalone tools like vim/emacs/ddd/etc. Windows programmers are more likely to use an IDE like Microsoft Visual Studio.
Unix programmers are more likely to use lots of homemade tools out of Python and Perl. Of course Perl and Python are available on Windows, but it isn't as widespread.
I have experience with a cluster of Sunfire V20z's running 64-bit Linux. It is not stable and we see kernel panics all the time. Fortunately this is a compute-cluster and we can deal with the crashes.
A Sun rep said we are one of their few customers he knows of that is using 64-bit Linux because of the known stability problems in the kernel. The hardware tests out fine and the reps say that 32-bit Linux and 64-bit Solaris are both rock solid.
I wonder if this is Sun-specific, or if 64-bit Linux on any Opteron is flaky?
As a graduate student, I really needed the original APUE book at one time but was put off by the $80 asking price (or something like that). Meanwhile, all of my Indian classmates brought their "Indian" editions with them which they acquired for insanely cheap prices. The difference is that these were often paperback and definitely were denoted as a special edition for India, but the content was the same. Very discouraging for me at the time because I had no way to acquire a discounted edition.
You want to improve public education? Then you need to get rid of the notion that every kid is entitled to the same degree of education. Sorry, life doesn't work this way. We need more tiers of education for the elite and the more mentally challenged. Of course there should be opportunity to be promoted/demoted.
In Japan, every student does not get the same education.
Id is still very small. Less than 10 programmers. Meanwhile all the big game studios have dozens of programmers.
I think Id chooses to stay small so Carmack can focus on making his 3d graphics engines. But to make a game nowadays requires lots of artists and run-of-the-mill scripting people.
Huh? I've been in graduate school for 4 years and haven't paid a dime. There is lost opportunity cost, but that is it. My tuition and living expenses are paid with extra. In fact my wife and I bought a house on graduate student salaries.
Thats right. A PhD in CS does not make a great programmer. A PhD trains and qualifies you to carry out research. A PhD creates knowledge instead of regurgitating it.
The Wisconsin Condor Project has been harvesting unused compute cycles for over a decade. The software is free to use and deploy, and is used by various corporations including Western Digital and others.

Sorry, but this NASA document says that they switched foam formulations as recently as 2001 to comply with EPA regulations.
Yawn. Copying a 2GB file over Gigabit LAN is faster than rebooting.
And can you give a good example why you would need to use one OS to process part of a 2GB file and then the other to finish the work?
Then they should buy VMWare. If your time is worth anything at all, the $200 license fee will be paid for by avoiding the hassle of configuring dual-boot and whatever.

You can't draw conclusions from what is in the dev kits.
Development kits are first cuts at hardware and often lack or contain hardware not in the final version.
