Yes, that has always been a major benifit of SCSI vs ATA. Since all the of the work is offloaded onto the controller instead of the CPU, it takes much less resources.
I remember my friend and I had an argument of SCSI vs ATA once. My system was all SCSI (see reference) and his was all ATA (like most). I told him there is a noticable difference, he wouldn't believe me. So we did a test, we copied the entire contents of the Windows 98 CD (yes, this was my frosh year in college - '99) to our harddrive and observed. Mine finished in half the time with next to zero CPU utilization, while his took nearly 75% CPU usage. He never said another word.
Granted this was a long time ago, and CPU's are fast enough to make this performance hit much less but it still proves a point.
I can't be certain for sure, but I know a *big* limitation of older IDE/ATA drives was that the controller could only talk to one device at a time (per channel maybe?) My guess is SATA would not have that limitation since it's a serial interface (no bus), but I know for sure that with SCSI there is no such limitation.
IIRC, SATA is also including some of the advanced SCSI abilities - TCQ/NCQ (read more here), but still falls shy of the complete list (including Packetization, QAS, & Negotiation and Domain Validation [reference]). Not entirely sure if those increase performance in any measureable amount, but I'm sure it doesnt hurt.
Ever since I had my new 2gb drive die (yes, that long ago) I wanted nothing to do with IDE anymore and gradually phased it out of my system entirely to all SCSI. Never been disappointed. Sure, all my friends joked for being anal about it but I was more than happy (except for the prices). For most applications there was not that big of a performance increase but if you partition your system intelligently across several different physical drives you can really see a difference.
SCSI on laptops? Maybe if you're hungry on the go and want to cook up an omelette real fast.
I'm sure that 10 minute battery life would be plenty of time to fry up a few eggs.</ducks>
Don't get me wrong, I love SCSI. My entire Athlon64 system is all SCSI (can't wait to upgrade to FC3) and it's amazing but I think that's something best left to desktops/servers.
Regardless, would you want to pay these prices for a laptop drive?? $447 (36GB) $838 (73GB)
Spend the money on education, let those who want to fry their brains fry them, let those that like to party occasionally have their occasional parties, and let those that are willing to remain drug-free stay drug-free. For most people, whether or not they do drugs isn't mitigated by the law, it's mitigated by desire.
Exactly my point. Spending the amount they have on the "War on Drugs" has accomplished little. Sure, they bust large operations and such, but in the end the "problem" as they like to call it remains.
We spend $50 billion per year trying to eradicate drugs from this country. According to DEA estimates we capture less than 10 percent of all illicit drugs. In this regard, I have a two part question 1) How much do you think it will cost to stop the other ninety percent? 2) Does $50 billion a year for a 90% failure rate seem like a good investment to you?
Making the drugs illegial is not going to stop the users from their habits.
At a time when working people are being asked to tighten our belts in order to help balance the budget, how do you justify increasing the funding to the drug law enforcement bureaucracy? Explain why supporting a failed policy of drug law enforcement has a greater priority than student loans or drug education programs.
Why should 270 million citizens continue to pay $50 billion per year to try to change the habits of 20 million people, considering that this policy has not been able to change those habits in 82 years and at a total cost of nearly one trillion dollars?
What do you conclude from the experience of Holland--a country where drugs fall under the jurisdiction of health agencies, not law enforcement--which has seen a decline in chronic use of hard drugs and casual use of soft drugs since de-criminalization?
I'd be willing to bet that the gov't keeps that information classified.
Regardless, this technology the NGA has light years behind what the NSA uses.
I could really care less as long as the quote "...But the NGA couldn't take actions to target a specific individual, such as highlight a suspect's home, unless the information was linked directly to a national security issue" remains truthful.
Besides, I have a strong suspision that if all commercial software was beautifully engineered we would not have open source software. Ugly commercial code developed under tight deadlines is, I think, one of the primary reasons may developers write open source projects, because thats where they have the freedom to do it right, without worrying about project costs or deadlines.
I couldn't agree more. This is one of the many beauties of open source projects. Freedom to do things correctly instead of quickly. I just wish all the managers (and executives) out there realized this, typically the only thing they care about is the almighty buck.
If that does happen, wouldn't it make financial sense for MS to start writing Office, Outlook, etc. for Linux?
They could, but I have this funny feeling if people would buy it, firstly they would obviously have to be running Linux, secondly (and hopefully) they already know about Thunderbird, Firefox, et al.
Maybe, just maybe, the general population will start to realize how much better the OSS equilivants are.
It all depends on the project and who's in charge. If security is not a priority in the project, either closed or open source, then it's going to have more bugs.
And this is the sad truth in many places within IT industry today. It really bothers me, but I can only do my part.
To anyone else out there: Have you ever dealt with this before working for an employeer and it angered/upset/whathaveyou enough to leave the company?
Yes, obviously it will be an approximation of the whole universe. It would be impossible to simulate the entire thing...
I had this idea for my science fair in high school, I wanted to simulate the universe but in a slightly different manner (I knew it would be impossible to do a good computational simulation this way on my home PC). Rather than running gravational computations on massive amount of particles, instead I used each star (or stellar object) as a data point, and created a group of equations to simulate how they would age according to known laws of stellar evolution. I also included some basic work on nebulas, white dwarfs, and black holes.
Since it took most of my time writing the equations to age my simulated universe, the graphics and front end were rather weak (320x200x256c). However, my sophomore year at NJIT I rewrote the stellar evolution part of my application in OpenGL with data from real stellar models computed at Geneva University.
Check out the application here if you're interested.
Never tried LSD, shrooms a handful with only one good experience (rest were weak batches and improper setting). I've known about lucid dreaming for some time although only experienced it at a low level (hey this doesn't make sense, got to be a dream... but that's the extent of it).
I'd be inclined to agree, I bet they have a lot in common and would love to learn/experiment more with lucid dreaming. Any suggestions?
I wouldn't say LSD is cheating at all... same for shrooms... or any other psychadelic for that matter. They take you to places you cannot go on your own, at least normally. Very very interesting places. I'd recommend it to anyone, assuming you can handle the brief levels of near insanity (that's why they call it a trip). It really does alter your life permanently - never looks at things quite the same way again. Potential for exploring the unknown (and just having an amazingly fun time) is very high.

All of your questions (and more) can be answered right here. But I'll answer these ones directly:
-Getting the real thing? Only an issue if you choose to do shrooms, potency varies *greatly* between patches. LSD is always returns consistant results. On the other hand, the fungus gets you about 6 hours total, while acid is 12.
-Music/environment/people? Tough one. Complex subject. I personally like the following: Pink Floyd/outside in the woods (no one else around plus nature is a great setting)/1-2 other people max who are tripping with me as well
-Things going bad? Always remember you have complete control of the situation. At times you might lose yourself (you will if it's a good/strong enough trip) but keep in mind you can change the way the trip is going at any time. If you feel funny and don't like something almost guaranteed one of three things will change it: Change the music, change the lighting, or go to the bathroom.
Since you mentioned you have smoked before, I highly recommend doing so right after popping whatever substance you choose. It will make the voyage from reality much smoother and not quite as abrupt. It sorta smacks you hard and fast if you do it sober.
Only other advice I can give is: "relax, don't panic and enjoy it". Try to take your mind off of what you just did after you eat them so you're not thinking about it all the time. I like to take my watch off and if you're out in nature, take a walk somewhere that will last at least 30 mins, preferably an hour (you'll start to feel it definately by then).
Very good advice but I'll take it a step further - Read the FAQ before you do. It will make the experience infinitely better, and if you follow it very closely your chances of having a bad trip will be next to none.
Although I have not read those books, I would highly recommend Erowid as an amazing resource for all kinds of information. Anything from chemistry, to religion/psychology, to laws and culture surrounding various substances. Seriously, even if you have the slightest curosity (don't we all?) then check it out. I used to keep a printed out copy of one of Erowid's FAQ's (*very* good I might add) on my coffeetable while living in my fraternity house and still in college. It was amazing the wide range of people who read and found it interesting, most of them had zero experience with those substances asides from the general fallacies.
That being said, please be responsible with whatever activities to choose to partake in.

Resistance is futile. We will add your distinctiveness to our own.
Of course you also have to realize that the keypress would be a violation of the DMCA and punishable by law.

At the risk of being modded offtopic:
Unfortunately yes, both Bush & Kerry seem to evade the issue here. Thankfully, Michael Badnarik marks it as a main point in his campaign.
Thankfully at least one candidate recognizes this importance of it.
I would agree on this one. I don't think it is the President's responsibility, I think it is more of a product of the society we now live in.

Very true... I've discovered the same thing myself, and honestly, I can't stand it.
It's sad to see companies just pushing out products as fast as possible to make the best buck, in the end it causes nothing but problems.
Anyone else encounter this with their current employeer or previous ones? I'd be interested to hear the story.
