This is almost identical to kernel scheduling problems, but much slower.
Context switching time vs process time vs smoothness
In response to your question the raw numbers are from HDtach (raw read), but real world numbers aren't far off. This of course depends on what you are doing. If I'm reading large (GB's) defragmented files, it's very close. I.e. VirtualDub, when the processing it's doing is less than 100% cpu utilization, leaving it to read as much data as it can get. Copying accross drives is only marginally slower. If I am copying many small files or heavily fragmented files, it's way off, but this isn't necessarily due to the drive itself. The filesystem is inefficient (ntfs), sending the head all over the place instead of sorting and sequentially reading the disc in an optimal manner, even though the data you read is not in the order you asked for it. I believe ext3 does this now, I don't know if it also does this for fragmented files.
Mr. Jackson's cpu's might be loaded with overhead from the filesystem, and/or the systems are just trying to serve too many files with too small a block size at once. For example if you want to perfectly load balance 4 read request for 4 different files, you'll have 4 access for each cycle, which would be 1 bit. This perfect load balancing is not necessary and this is why large block size is important, for 4 simultaneous 100Mb files instead of 3.2 billion accesses, with a 32k block size only 12.5 thousand accesses. That's alot of access time. I bet he just needs to do some tweaking. How long can an application go without data for? How much data can you read within that time? Use a huge blocksize, if not hardware block, modify the software so it makes sure to read X amount of a sequential data before moving on to the next request. Not very smooth, but lots of "process time"
Are you kidding me? That's why we have ATA/133 coming out, because IDE drives are getting that fast, oh wait, that must be 133Mbits/sec (*sarcasm*) (yes people have told me this)
Try turning on DMA, you absolutely _need_ DMA turned on for modern drives, PIO Mode 4 maxes out at 16MB/sec with 100% cpu utilization, PIO Mode 5 isn't official and will most likely break your hardware. After you turn on DMA you can set your interface speed at 16/33/66/100/133MBYTES/sec.
I hate to repeat myself but here are the Specs for ST318452LW, Cheetah x15
Internal Transfer Rate (min) 548 Mbits/sec Internal Transfer Rate (max) 706 Mbits/sec Formatted Int Transfer Rate (min) 51.8 MBytes/sec Formatted Int Transfer Rate (max) 68.1 MBytes/sec External (I/O) Transfer Rate (max) 160 MBytes/sec Avg Formatted Transfer Rate 61 MBytes/sec
There is no such thing as true sustained data rate, it will always peak at the outer side of the platter. Using Hdtach 2.61 the maximum is around 65, which slowly decreases to the low 40's on the inside. My maxtor 80GB (98196H8) drive gets 30MB/sec on the outer side of the platter, I might have highballed that number on the inside it goes to about 19MB/sec.
Keep in mind that as platter density increases, and speed stays constant, transfer rate goes up. So a 5400rpm 80GB drive with 4 20GB platters will be slower than a 5400rpm drive with 1 80GB platter.
Sequential reads on my drives can go from 25-65MB/sec (maxtor and cheetah), if the file is heavily fragmented I've seen it drop as low as 5-10MB/sec. Not so bad on the 15Krpm cheetah because the access rate helps, but on the lowely 5400rpm maxtor fragmentation destroys read/write speeds.
This is just something for people with too much money to get their panties in a tangle about.
Prehistory isn't prehistory because there wasn't history, but because no documents survived the battle with time. We already know the people traveled to NA before Columbus.

Tis but one way to find the guilt of this hacker. Attach a large stone to his leg and throw him into a lake. If he floats the water has rejected his evil hacker body and he is guilty, if he sinks he is innocent!
I have had already done everything in that article, but I tried a _local_ file search, no connections, closed the search window, ~30 seconds later 3 connections to sa.windows.com, from the shell explorer.exe process. hmmmm? Subsequent searches (from a different explorer.exe instance) caused the shell process of explorer.exe to immediately connect to sa.windows.com
This isn't just internet searches, it seems to be reports local searches on local files.
For everyone who says that spying is OK for people beneath you because they don't know any better, there is someone above you saying the same thing about YOU. If this happens to teens, it will eventually happen to everybody.
Fictitious scenario from the future follows:
Officer: Did you notice your brake light is out? Oh, wait, I see here that you're coming from the Anti G.W. Bush activist convention Why don't you step out of the car sir.
American citizen: Uhm, yes sir officier (uh oh).
Officer: So you don't like my country huh? You no good punk/commie/terrorist/hacker/etc.......
The rest is up to your imagination, imagine if you're a "brown-American" in today's context. Of course this is a best-case scenario. In the worst case politically incorrect gatherings, civil disobedience, and activism, which are the the cornerstones of our way of life would be eliminated, because it's damn near impossible for people to get there.
Of course none of the R/W computers will be in any way attached to the internet.... in the best possible setup a machine that has access to both networks can be compromised, etc. If it's not, updating will be a major pain, so much so they might as well flip the read-only jumper on the drives between updates rather than use this system.
Aside from the obvious, there are much better uses for more than one head in a drive. Multiple simultaneous seeks, faster seeks, and twice the raw read rate. The market for this should be huge. Hard drive transfer rate is the bottleneck for most tasks, including boot time. All the while with less heat, power, and noise of the 7200+rpm drives.
Perhaps there isn't a business model to be had, that may be a better than any business model. How much money did musicians make before records that you could sell? Not much, but they did anyway, and we have a rich and diverse history of music. After the record industry got started, musicians still made almost nothing, just a few fatcats who had the money to invest anyway. With better contracts and sales of multi-million units, some artists have made a decent amount of money, but this is an infinitesimal number of all musicians. All the while some pseudo-anonymous fatcats with little talent but a large pile of cash, are making their pile larger.
The time for super-stars and immense amounts of wealth for the few may be at an end, at least for this industry. I welcome it. How many bands that have gotten silly, filthy rich produced a good album afterwards? Exactly.

They tried to make an example out these few, look it's working great. Then they'll put the thousands on thousands of couriers in jail, then they'll put non affiliated users in jail. It works just like imprisoning people for marijuana possession. The US prison industry is booming, that's what will bring us out of this recession, a profitable prison system driven by slave^H^H^H^H^Hprison labor. When it's all over, that's all we will have. Everyone in prison.

Last time it tried to take pictures it shut down in failsafe, now there is a high probability it will do so again, in which case 1.5mil would be wasted, which NASA can't really afford.
I've been doing it for over 4 years now. I used to weigh 165+lbs at 5'7" and bench press 95lbs, and now I am 142lbs and I can bench press 225lbs+, and I'm still getting better at losing fat and gaining muscle/strength. Tomorrow I will be in the best shape of my life, everyday. I did this all through college, where your diet isn't always up to you (for meal plans, or lack of cooking skills) I've tried many, many schemes and I've monitored my strength/fat/weight/etc finding what works.
I can tell you the low-carb diet is one of the best tools to "fix" your body. On a "regular diet" you WILL lose both muscle and fat at the same time. You _never_ want to lose muscle mass. On a ketogenic diet you will retain muscle, and if training properly can gain muscle while losing fat, something that is also thought to be "absurd", just like the atkins diet.
How do you do it here in reality? Yes you want to eat healthy, and you also live in the real world. That's why you start with a glycemic index chart. Scratch of everying on the top of the list, sugar, corn syrup, potatoes, pasta, etc. This doesn't mean you can never eat them, but if you have to have fast food, skip the fries and the drink, get water. Use substitutes from the bottom when possible, i.e. want a sandwich? some breads are a lot better than others.
Should you eat bacon and butter? No... but you can, and not feel guilty. Can you have the piece of cake? how about some chocolate? YES, but you have to remember that you WILL CRAVE food/sugars after you've had it, and just remember to keep yourself in control for the next 12/24 hours, and you are all set. Balance fullness with hunger, cold calculate what you have eaten and what you will eat, don't let you gut take the wheel, show it who's in control, and it will stop complaining.
Ramen-easy type meal? large chicken breast, bbq sauce, 6-10 minutes of cooking. Just eat it with some water to drink. You won't crave anything or be hungry for hours. A little quicker and unhealther? frozen chicken strips, whatever flavor skip breading if possible. A few minutes in the zapper and you have a meal that will keep you content, no snacking on cheetos by the keyboard, we know how dirty those can get! (and you won't want any)
In the end understanding the process that no/low carb diets put you through will allow YOU to master YOUR body, just as you may wish to master a network/computer/program/etc. and you will find many other "little" things you can do (like not eating 3-4 hours before bed) that keep you healthy, lean, and strong.
At 181KBps download rate, I could download 469GB per month. If I do nothing else but watch my favorite streaming program, which runs at ~70KBps, for 30 minutes each day, I am using almost 40GB per month.
No that is a MYTH by the cable companies. Code is quite right, a digital code is transmitted on an FM channel on the cable, this tells the cable box things like the channel name, the current time, what channels it should get. You can hook up a radio to your cable and listen, it varies for different brands of cable boxes. All a "bullet" does it tell it to shut off all channells, usually remedied by unplugging the box for 15 minutes. All the notch filter is is an FM trap.
