3 and 2 GHz procs and 1 and 2 Gigs of RAM are minimal HW!? I run Leopard happily on a 1 GHz eMac at home and Tiger on a 450 Mhz G3 tower at work both with 768 MB of RAM. FreeBSD and XP run great on a 750 MHz PC with 512 MB RAM at work as well.
No BD-ROM and HD-DVD both use 'blue' (really closer to violet) lasers. BD uses a different data encoding to achieve more data density and uses a more scratch resistant coating on the disk itself to counteract it's lesser ability at handling read errors.
It could be scrambled in such a way as to not appear as a key. Then unscrambled into a register. The paper talks about that as a decent countermeasure. It would slow down the encryption/decryption though.
VIA had a while back some registers that you cold tweak to lock L1 cache lines. I don't know if modern VIA chips still have this. In the X86 world I do not know of anything similar from Intel or AMD. You might have better luck using unused registers in the CPU (debugging registers) or external chips (chipset UART regs say) but then you really would not be able to use those anymore, but there may be enough legacy registers around not really used anymore to make it work with the penalty of it being very slow.
Because these wealthy business owners are donating large amounts of money to the universities anyway. It shows they have a conscience and are not simply involved in the race to the bottom.
The universities and labs in the USA are very good. The problem recently is how much harder it is for foreign researchers here and the funding of the labs. But if things continue the way they are then yes we will have a cesspool here.
Um, no I don't that is why I said there was no hope for it in the stimulus bill, it really cannot be justified that way.
But some law makers trying to squeeze in things like road improvements don't seem to understand the party-line rational either. You could have law makers try a similar thing with science funding, under the same rational - building roads gives jobs : funding science projects employs technical people - in both cases the economy is stimulated from these people spending, not filing bankrupcy, etc. But again this is not the party line of how a stimulus package is supposed to work and so will not fly.
The way it is supposed to work according to the administration is cutting taxes is supposed to stimulate spending. For individuals they are supposed to spend that money. There are two problems with this though. People are so in debt and banks are ratcheting back new credit card offers that they are at unable to spend it in ways they would not otherwise so the stimulus is questionable. The other problem is that it creates debt with interest for years later. That is not necessarily an impediment to the economy down the road but will make things like science funding later harder to justify, which is what this slashdot article is about.
The corporate tax breaks are really what the stimulus package are about. What I have heard says that there will be tax breaks for corporate spending. Again this is a ruse. Businesses will simply not spend on new equipment when there is no demand for what the business produces, tax break or not. What needs a reall kick is basically the banking sectoer and bond insurers. The Fed has helped with the recent rate cuts, it is to be seen if the stimulus bill will address these two areas. What I expect is that there will be bailouts for the well connected, again the true reason for the stimulus plan, not really to stimulate the economy.
So I see how this derailed the discussion from science funding, well done. Isn't is interesting that precisely funding building and science projects so people can be employed is about the only stimulus plan that would work, but it simply will not be allowed because that is not the party line of this administration. The true reason behind the stimulus plan is to provide tax cuts to those in well connected positions and that is what it will achieve. Oh and the democrats will attach some welfare spending.
This is a lame duck president. Congress will wait for a new president before doing anything. Before the budget will get passed there will be at least one continuing resolution where funding will be at the current very low levels across the board for science. Then Congress, realizing it needs to deal with the ballooning budget problems, will need to pass a lean budget for science in order to fund things like welfare. Only NASA will be largely spared since it is so spread-out over many Congressional districts.
There is no hope for science funding in the emergency stimulus bill and only a little hope for a April/May supplemental appropriations bill tacked onto war spending. So there will be a long time at 2008 levels of funding and then cuts and basically level funding for the rest in the eventual 2009 budget passed by Congress and signed by the then president.
Don't believe me, read what the Director of Fermilab thinks:
The only real hope for science funding is through universities really. If you know any university trustees, let them know about the problems. If these wealthy and well connected people feel that their companies are at risk due to the US trailing in science, then they can make an impact with Representative and Senators. We need more people like Craig Barrett, the chairman of Intel, expressing why science funding is key.
I still need to use ARCnet to this day. ARCnet sort of found a niche in realtime/embedded for a while. We have old systems that are ARCnet. One nice thing for realtime is you can predict the timing better than half duplex ethernet and there is a way in which we know whether who we are talking to is alive before we talk to him. The bad part is that the systems we talk to over ARCnet are so old that means that they are slow and we need to wait an seeming eternity for the response. ARCnet is also useful to bridge a safety and controls network. You can have a node that gets alarms and readings from the safety system via ARCnet and distribute that via ethernet to operators.

Wow wordpress can't handle./ AND it creates craptastic HTML. Forgive me if I screwed this up fixing all of the empty anchors.
The demoscene first appeared during the 8-bit era on computers such as the Commodore 64 and ZX Spectrum, and came to prominence during the rise of the 16/32-bit home computers (the Atari ST and the Amiga). In the early years, demos had a strong connection with software cracking. When a cracked program was started, the cracker or his team would take credit with a graphical introduction called a crack intro (shortened cracktro). Later, the making of intros and standalone demos evolved into a new subculture independent of the software piracy scene.
Prior to the popularity of IBM PC compatibles, most home computers of a given line had relatively little variance in their basic hardware, which made their capabilities practically identical. Therefore, the variations among demos created for one computer line were attributed to programming alone, rather than one computer having better hardware. This created a competitive environment in which demoscene groups would try to outperform each other in creating amazing effects, and often to demonstrate why they felt one machine was better than another (for example Commodore 64 or Amiga versus Atari 800 or ST).
Demo writers went to great lengths to get every last ounce of performance out of their target machine. Where games and application writers were concerned with the stability and functionality of their software, the demo writer was typically interested in how many CPU cycles a routine would consume and, more generally, how best to squeeze great activity onto the screen. Writers went so far as to exploit known hardware errors to produce effects that the manufacturer of the computer had not intended. The perception that the demo scene was going to extremes and charting new territory added to its draw.
Even with modern technology, where much of the effects seen in demos could be replicated in programs like 3D Studio Max, the point of demos are not just the beautiful visuals and music but the abilities of the programmers involved to write code so tight, so efficient, that something might be several megabytes if rendered in a 3D program comes out to less than 100k. So heres IHCs favorites from the demo scene of the last few years. These demos are in no particular order, and while weve provided Flash video links to each demo, the greatest joy is downloading them (PC only) and giving your graphic cards something fun to chew on.
I am only 30 but I had trouble reading the text in the weather page he mocked-up. Maybe it was the compression in the video, but I much preferred the larger text.
Basically profile and tick are useless since they will not fire if a thread with PT_DENY_ATTACH is on proc. Perfectly good DTrace scripts simply will not work correctly on OS X.
I used a 4 MB USB flash drive. Yes only 4 MB, but larger than the 1.44 MB floppy it replaced. Before that I was using 100 MB Zip drives before the click of death.
Oh dear LORD if this app will be deleting files in such a manner you will break SO MANY things. Just do the honorable thing, pull it before it does serious damage.
I plug my flash drive right into the side of my keyboard. I have not used a floppy in more than ten years and a modem in more than seven. In the iMacs I do wish the headphone jack was on the side like in an eMac.
First the Air is not a subnotebook, it is a very thin notebook. A subnotebook would need a screen no larger than 10".
I just priced a Dell XPS M1330 and it comes to $1,304 with 40GB more hard drive space (you can get a 64 SSD for a grand instead) 128MB graphics card, bluetooth, wireless-n, CD/DVD+/-RW, 8-in-1 memory card reader, firewire, more USB 2.0 ports, removable 9 HOUR battery, 1.66 GHz core duo 2, 13.3" lcd, 2.0 MP webcam, and an expresscard slot. The depth and width are the same and it is only half an inch taller and less than a pound heavier.
So except for Mac OS X it does not even come close to outclassing the Dell and it is $500 more. Sure if you compare it to a Sony then the Apple is a better deal but Sony is consistently very expensive and that is why Jobs chose to compare the Air to it.
I suppose with a thermal diode used as a thermostat you could do something like this. I had to do some temperature measurements a few years back with 350 MHz PPC VME processor bards used in realtime systems to see what the worst case scenario was when all the fans in the crate were off. I was only able to get almost but not quite 1 C/min and that was in a crate where the boards were horizontal and when I was using the CPU, memory, and IO to maximize the heat generated. I could see a chip that does something like that to let you run more cores for short burst of time. (The PPCs could shut-off unused parts of the die, just cut-off clock and since it is CMOS virtually no power used heat generated and you could dynamically change the clock multiplier so you don't even need to use multiple cores.) You could have firmware in the chip that also ties the thermostat to a bus cycle counter to prevent people simply using the less expensive models with better cooling.
But I am unsure how this would really make sense economically.
The signals around here used strobe lights. Now they also install a camera on the light to see who is using it. I am sure it is only a matter of time that the cameras get used to send tickets to those who run reds.
It does. There was just an incident where for two days a QuickBooks update for Mac would delete a user's entire Desktop folder and replace it with an empty folder with incorrect permissions:
I had most of these before I married and had my first kid, but the Mattel Aquarius was the worst ever. Even worse than the original PET keyboard. On the other hand later PCjr keyboard was actually my favorite of the early computers. It was very flat and had no wire. Plus I had a number of adventure games for it. I eventually made a power adapter for it with some electrical tape, nails, and the brick from an broken answering machine so I did not use batteries anymore.

I JUST ran into a script like that! It made a bunch of us here chuckle. Guess how and when we ran into it.
That's interesting as mktime() returns -1 on error. I hope you have been writing something like this on all those systems:
...
t = mktime(tp);
if (t == (time_t)-1)
...
Personally I know that single pesky one based field ALWAYS screws me up. (Brain why, WHY WON'T you finally learn!?)

Or just give them static IPs. You can have the rest via DHCP for convenience even if the IP is fixed.
I just have two ports open for this. You only need it for the initial incoming connection. I only had to do it once.
