Quick question, when harddisks fail, you do you know which one failed? I have two drives in a raid. and they are mapped as sda and sdb. I dont know which drive physically goes to sda and sdb. (I am too lazy to figure out which one is which). But what is done generally to determine which drive has failed physically? DO you just keep track of which drive is which by port its connected to etc.?
The problem that you describe can also be applied to having multiple cores. If you read the article you will realize that they have taken MANY steps to prevent this.
For one they use ddr3 memory. Another thing is that they have much more intelligent pre-fetching mixed with the loop detection thingy. The cache size/design itself allows for many applications to run.
The problem that you describe is a problem with the OS's scheduler. It should understand the architecture that it is running on. It should know about the types of caches the way each processor shares them. etc. Thus, it only makes sense to use hyper-threading if 1. you are simply out of cores (the choice of using ht cores is iffy) 2. a single application has spawned multiple threads. Even then you have to take into account the availability of other cores that share the l2 or l3 cache.
I personally think that intelligent pre-fetching and loop detection thingy is something that needs more tests/statistics thrown at.
Like you say, there are some applications that take advantage of HT let them take advantage of it while writing smarter OSs that understand the problems with doing so.
Maybe they need a feed back mechanism from the processor for the OS to understand what is the best way to schedule tasks.
I dont know much about CPUS:-p, just from what I read and learned in school.
Umm, I knew a person who managed a very large botnet. He use to be able to take down the internet for a general area. He use to have "wars" with other botnet people and you would notice the internet gone for a few hours, in my neighborhood at least.
Then he was hired to take down a website in the west side of the Pennsylvania. He actually took down the internet for the whole area. Banks there couldn't communicate and all that. Well, he was caught and spent some time in prison. Now he doesn't really fit in with society any more and spends time in and out of prison.
After taking a geology course, you learn that green house gases are the least of our problems. The worst that's gono happen is that the human race will be wiped out. Big woop. Evolution will fix that in a couple million years.
Wow all of the comments are from people who worship the 360 or are trying to stimulate a ps3 360 fanboy battle.
I didnt see any comments from the ps3 guys so I ll say a few words.
actually now that I come to think of it, i have nothing much to say. If I say I love it you guys will assume I am a fanboy, but the fact is that Iv never had a playstation before. I had a nes, snes, n64, dreamcast, gameboy (the old brick one), DS, wii, and now a ps3. So i was never really a fanboy to begin with.
How can I say this with out sounding fanboyish? ps3 was well worth my $600.
(the 360's costs are starting to add up arn't they)
I agree. My wii is sitting there collecting dust and heating the dvd cases that are placed on top of it, even though its off.
But anyways, I am glad that these games are coming out, but im not getting my hopes up in any way. I am going to wait patiently and play my ps3 (actually top rated ps2 games, since i beat all the ps3 games i wanted)/PC and wait for the reviews to come out.
I dont understand how I am suppose to have fun with the wii. (have wii play, i love golf and zelda i cant adapt to the controls I hate writing with a pen/pencil and i hate drawing so i hate swinging the remote)
But the ps3 is something I get.
I guess I am too old to learn new things.
PS3 was well worth the $600. I am still iffy about the wii.
I know my view of video games isnt popular, but it is still AN opinion.
The things I learned: 1. 4mhz processor is REALLY fast! 2. How the stack works. 3. How absolute and relative jumps work. 4. How to create "objects" and implement "methods" 5. How the smallest variable, the register works.
I have to say that after making games in assembly, I am actually disappointed in how well the current consoles handle them. I would expect them to be able to crazy things with the hardware they are given. That is also why I am interested in the ps3, it forces programmers to understand the underlying hardware.
I thought i was the only one freaking out. I am thinking about deleting my facebook account.
What facebook people dont understand is the word "friend" doesnt mean you like the person, or even want to talk to the person. It just means if you met them on the street you would say HI.
Damn man why dont you just put a damn camera on me and allow everyone to see what I do.
Great now were gono have copyright laws and drms for smells. You can only smell George Bush's fart ONCE. You cannot skip through the commercial smells in the middle HEHEHEHEHHEH. poo jokes are funny:-D.
Also, I know that perfumes are going to have big problems with people stealing the smell and posting it online. I wonder what format it will be in...
I think people will buy windows xp instead of moving to linux. Most of the expensive hardware becomes useless if you install linux. People don't want to spend hours trying to figure out how to get their tv card to work. I would love to completely switch to linux, but I have only been able to switch my laptop so far. I have trouble getting my video card to be recognized properly. But my problems aside, windows offers a standardized way to look at a computer, from a user and a programmer's perspective. It might be shitty but its still the same on any windows pc you go to. A user is not going to try to relearn the interface and everything else, especially older people.
The reason people won't switch to linux is because it is designed by professionals for professionals. And I am pretty sure if you measure the professional to non professional ratio amongst computer users, it will probably be equal to (linux):(microsoft + mac).
they actually have this feature. You right click on explorer and click run as. Then type in my computer on top. any thing you do from that window edit/run will be done as who ever you "ran as".
This feature probably will not work on vista because after I installed the new ie 7 i could no longer goto my computer from the browser.
I am a big linux fan, but I still would not recomend it to anyone who doesn't know what assembly is. Linux needs to learn from windows' trials and errors. Come on fokes, all I am looking for a distro backed by linux, where I can give the cd to my brother and it will install as easy as windows. Meaning for compatibility issues, make a wrapper that reads windows' driver files. I have no clue how you can do this, but if you can do it, I promise you windows would dissapear from most computers.
I work at my college as a web developer for the CS department. My college is also like 20 minutes away. So I just commute to work and school and I dont pay for college.
Xbox 360: I dont know anyone who has it. Maybe I am getting too old (still a teen though). I want a next generation system but I am willing to wait because I know the first system out is not always the best one. Dreamcast *ahem* Which I still love:-).
Wii: This is something that shocked me in a good way. I was just wondering how videogames would be in the future, and this one hit that spot on the head. After looking at the controller and watching people play it at e3, I am ready to forget how to strafe and shoot and circle around the guy and own them with my analogs (My teacher would write RO). Because games these days even first person shooters are confusing as hell. I seriously felt like it was uncivilized or something trying to play with a analog stick. And then I got back to reality and I realize that this was my only choice. FOR NOW:-D.
*off topic* I was playing halo and owning my lil cuz, untill he took out his sword and kept killing me. I thought their was some skill behind using it but now I learned you just look at the guy and press the shoot button as fast as you can HOW RETARTED IS THAT. and obviously being an old school gamer I could press my fire button the quickest:-p.
PS3: The current discussion. First I would like to say I have a pretty decent job and I am living with my parents and going to college so I am not really worried about cash. So my opinion might sound stupid. I WANT IT. I WANT IT NOW. I know I am not gono play it at all after I get my wii, but I still want it. I am not getting a freaken hi-deff tv to see huge pixels and miss drawn shadows. The fact is I am living in the year 2006 and I want to see some tech that will blow my mind. The cell processor sounds crazy. I am majoring in CS, actually almost done with it, and the cell processor is something to really look at from a scientific point of view (for me any ways). I have made games before for my ti-86:-D. http://www.ticalc.org/archives/files/fileinfo/232/ 23280.html (screenshots included) that is a freaken side scroller on a z80 4mhz processor baby and I soo wish I had another processor processing just graphical crap that wasn't really important to the game play but for "coolness".
So wii is a given. And my other choice is between xbox 360 and ps3. I have xbox and I truthfully play my dreamcast more then the xbox. Kinda sad I know. So I am willing to pay for a pretty looking ps3:-).
PS: can we get a freaken spellchecker in here. What is this web 1.0?

I think I use telnet as a browser more then any of the above mentioned.
I am not sure how they caught him. But I guess he wasnt smart enough to remote into the botnet or something
Umm, I knew a person who managed a very large botnet. He use to be able to take down the internet for a general area. He use to have "wars" with other botnet people and you would notice the internet gone for a few hours, in my neighborhood at least.

As a desktop linux user, has anyone EVER gotten a virus? Or better yet has any anti-virus program saved your ass?
Give it a rest al gore.

Gatta look at the BIGGER picture!
Mac fanboyism to the MAX! I don't write that detailed of a description for proofs in my classes!
I remember one time I was trying to abstract an event handler. The code when something like this:
obj.onload = function
I dont feel like explaining what was the problem so Ill just say what I wrote to fix it
obj.onload = function
if (obj == window) window.onload = function
^^ basically window.onload was a "hack" if you did x = window; x.onload = function; this wouldnt work.

Wow, the first programming language I learned was z80 assembly :-). I use to make games for the ti86.

here is a side scroller i made written all in assembly (includes animated screen shot)
http://www.ticalc.org/archives/files/fileinfo/232
The things I learned:
1. 4mhz processor is REALLY fast!
2. How the stack works.
3. How absolute and relative jumps work.

So i can have only my friends -acquaintances view my stuff?

Hasn't this type of attack been taken care of by the introducion of salts and spices :-D. FBI needs to update their software!
