depends on your usage, a shot list of typical for me; re-encode/stream video files to my ps3, World of warcraft, rip/encode of a dvd, emerge (yep i run gentoo), some sort of flash based music player(pandora+chrome is 17%-20% cpu). Seeing as all of those are rather CPU bound, WoW need GPU and IO as well, I'd love a machine with 32cores or so. toss 1-2 at the streaming re-encode, 2 for wow, 8ish for the dvd rip/re-encode, and say 3 for chrome. so thats 14-15 cores before emerge. I can make emerge consume just about as many as i want. Granted i would need like 16GB of ram to keep all those core happy, and probably a raid of SSDs and a better controller, but thats life:).
but look at the differances in energy per unit mass. Fans, while good at moving air loose alot as soon as there is some sort of obstruction in the way, getting a fan to move more than a few (1-3) inches of water worth of pressure is quite a bit of work. so while oil may be harder to move you need to move less of it or it can move slower. You are correct that you need to move a specific thermal mass to cool a heat source.
You should see McLaren's new little scoop thing on this years cars[1]. It allows almost exactly what you are describing, effect wise anyways, as of right now it is worth about 5MPH down a straight way. This isn't so much about changing the cars surfaces, but changing the way air flows over them and making them not produce as much downforce but a lot less drag.
it also depends on the topics you are researching. I've found it great for hard science topics. Look up one of those carbon-carbon-temp steel charts(sorry the name eludes me after 4 years), it is going to be accurate. The page on the culture of Pakistan is likely to have a lot of mistakes in it. It really depends on the topic. I tended to use wiki a a broad overview of the topic, and then read the sources at the bottom of the page and used those on my papers. The hardest paper i had to write was the one about how tachinite is made, it needed too many sources, I'm basicly 3rd-5th gen Minnesota iron range, i know how the mines work, how the peltizer works, etc etc etc, out of my head, all from talk and walk throughs of mines. no sources needed to write a paper, but it needed 6 or something and 2 had to be magizines/newspapers.
Lead times consume capital by having a large amount of parts in "inventory" if you fill a container ship full I7-920s thats a heck of a lot of money tied up for 3 months(in your example). If you could make the leadtime for the same shipment 3 days, and cost less than 10x more, i train i'd wager is close to only 2-3x that of a boat, as well as less likely to loose the whole shipment.
from TFA: The last line to be built will connect Germany to Russia, cross Siberia and then back into China. The exact routes have yet to be determined
looks like that is a planed line already. Why is there assumption that the line would go though the most hostile of countries? it could easly go along the southern borders of Iran and Pakistan. avoiding a large amount of conflict. Also in some of those cases ensuring a 0 stop trip would be enough to be allowed to skip most of the checkpoints.
that wasn't his point, it seemed he knew why We don't use the train. His point was why does our suck so bad, it's not like we are hard up for 20'-100' wide swaths of land for the tracks, and with the fairly open spaces between population centers it would seem that we could easily add high speed (180-250MPH) interconnects, it should be cheaper than a plane and use less fuel to boot, no worries of it crashing into a building either. As was mentioned above there is a "mass transit is for poor people" mentality. There also is a "I don't want to spend money on anything that might help anyone else out at all". Fixing potholes in the highways/freeways around me is hard enough, let alone adding rail. we are slowly adding rail line though, but what do you do once you get into downtown? the buses don't really work here as they are now.
Actually from what i understand, most of the factories in china could make anything at just about any level of precision required, but as you move up the precision scale it costs more, at some point the shipping across the ocean outweighs any savings you could have made and so it's made locally. shipping in both cost and as in lead time, shipping from china is about 3-4 weeks minimum.
I'm sure they would like to see things shipped faster, but I think their major market is the USA, I'm not sure how much time a trip to the UK would save. Now it would likely open up some more market share in Europe, as well as some tourism. The way it is, a trip from Germany to the south of Italy is around two days via train, IIRC. Even if it was a three day trip to get to Beijing, the trip across the countryside would be well worth it. It's also likely cheaper than a plane ticket and all of that hassle. I wonder how feasible an interconnect at the bearing straight would be. I'd love to take a train to China and Japan for a visit. or for that matter just to Alaska or anywhere else in the USA. yes I know and have looked at amtrack, and while it is cheaper than a plane it has some dumb hours. Like a 3AM arrival to a closed station in the middle of Lansing MI. Not so good for a family sort of travel.
even app signing wouldn't work, it would ahve to be open enough to allow small outfits to produce code, and would need to allow dev to test run their code prior to the app signing. Both of those are holes, whats to stop a hacker from making a legit app and then using the same cert on both it and the malware?
*nix without admin rights, and their home dir mounted no_exec with backup taken every 6 hours, admined by dell/HP/etc. No way to install a new app, and no way to run something from the home dir, problem solved.
really? i though a simple rev limiter would be better than a neutral gear lockout. there are times (like when these acceleration problems happen) that you need to remove power from the wheels now, engine be damned. to be honest, i wonder how many driving problems would be solved simply as defining the automatic transmission as a "for disabled persons" only, like the handicapped parking spots, and making everyone drive a manual transmission. it's really hard to do makeup and shift and steer all at the same time.
driver error in the way the effects were handled. why are drivers that don't know what to do in the case the car provides more power than intended allowed to drive? Yes, I expect people to know what that little N just above D means. Can't be bothered, I guess you don't need to drive.
I'm still failing to see how the cars got locked in gear? every car i have driven has allowed the driver to shift the car into neutral regardless of everything else. This is both in automatics and definitely in my manual transmission cars(does anyone make a drive by wire clutch, outside of performance/race cars?) I fail to see why this is a huge issue that needs to be solved in the next 10 minutes and be 100%? how is a sticky peddle (software or otherwise) any different from the throttle body getting stuck in the wide open position? what would these people do in that case? The handling after the problem occurs seems to be 100% driver error. TBH the first that that would happen if my car started doing that would be for me to press on the clutch, regardless of it not having one or not, thats a very hard habit to break after driving manuals(not this behavior in an auto usually results in the the break being depressed all the way to the floor). After that i'd put it in neutral and then use the break to slow down and pull over. somewhere in there i'd hopefully get the 4 ways on, but thats a long long way down the list of things that would happen.
The "PR shitstorm" is way way over-hyped, it would be simple for the news to simply state "Toyota has confirmed an issue effecting the engine speed controls, and have issued a recall. If this happens to you while driving Toyota advises drivers to shift the car into neutral and engage the 4 ways and pull over in a safe location. If your car has a push button start be aware that you will need to hold it down for up to 5 seconds to shut down the engine." The fact that some people have died as a result of poor driving ability is no different than every fall here when it snows and some dumb person forgets that snow is slippery, a terrible thing to have happen, but usually 100% their fault.
I think the driving tests in this country need to be much more rigorous. They should be done in an unfamiliar car, setup for simulating things like sudden loss of engine power, loss of 90% of the breaks, etc. There should also then be a road test(with other real cars if the closed course goes well.) to see how the driver can handle the conditions of real driving. Places with snow/ice need to have some driving on a slippery surface(rear wheels that can be allowed to rotate would work.) This sort of testing should be repeated every 3-5 years, to ensure that drivers maintain a certain level of driving skill. There needs to also be a raw reflexes/object tracking with a fairly high level of skill needed, anything below a certain level will see that you fail your driving exam. Fines for driving without a license should be steep and the test facilities need to be open at least 2 shifts of the day, if not 2.5 shifts.
All of the apps I care about on my mobile platform have either been rejected by apple/ATT, are not available, or just not unique enough for them to be stuck to the iPhone.
A short list off the top of my head; a terminal with SSH/bash, a IM client capable of connecting to just about everything(pidgin/empathy), VNC/rdesktop/X11 forwarding, webbrowser with flash that supports doing things like running a flash app(pandora/lastFM) in the background while doing other browsing.
The thing really killing the iPad for me is the lack of multitasking. If i have a device to read ebooks on, that can also play music I expect to do both at the same time. I also expect it to not care about bandwidth hungry apps when on wifi and even to some extent on 3G. I can manage my bandwidth pretty well on my own thanks.
For me the linux tablet isn't so much about micromanaging what it does, but the fact that I'm looking for a couch browsing device that can then also connect to my desktop/HTPC and let me do stuff to it. Boxee/XBMC/mythtv remote anyone(even better if it's easy to add an IR LED to it so it can control other things too)?
gestures are easily done as key strokes, by watching for the gesture and then sending a keystroke, should be relatively straight forward in X. Why does an on screen keyboard need to care about the app under it? just send keyboard events to the window focused. Why does it need to do spell checking we are talking about 10" screens. my current keyboard is close to that size already(the small apple Al keyboard). the flicking thing seems a bit of a showy gimmick to me. whats wrong with the scroll bar? just make sure it's wide enough to be easy to hit, or for that matter, when you "flick" it sends a scroll wheel event(s)(buttons 4 and 5 on a mouse). QT4 should all but eliminate the need to ensure that your app works at 2 different resolutions. It handles things like growing and stretching the size of the window very well. It also has support for setting methods to call on resize of the parent window, allowing you to then check the size, and swap between the portrait, and landscape UIs. Why does the app need to know about the input methods? shouldn't the GUI toolkit(gtk/qt/etc) handle that for the app developer. Now if you are making a game on linux, my suggestion would be to look at SDL and OpenGL.
I'm willing to bet that most of the apps sucking on Andriod and WinMo, is that app developers don't let the UI and underlying stuff handle placing things for them. They instead try and lock down the UI so that it looks the same everywhere, and makes it harder to just let the toolkit handle low level things for you.
they have your name and address, what they don't have is the speed of the internet at your location. so in the end all they have is that for a short period of time(who in the home market pays for a static IP?) you had a certian IP, and it had X, Y, and Z available to it at the time.
Why am i tempted to turn on the QOS in ddwrt to run the test? is that bad?
I'd like a 4 or 6 core machine for doing things like play wow, libx264 encode, gentoo emerge, firefox with a flash based music player all at the same time without noticing. granted i can do a good chunk of that on my Athlon X2 but it requires some nicely set priories.
because memry bandwidth isn't much of an issue on AMD, the controller is on die, all it is a bunch of wires. Maybe my motherboard has enough on it for me, but i'm waiting for a board with USB3/(insert other feature here) on it. so i can make a 3/4 upgrade now, and then when a board comes out buy it and drop it in. instead of going hmm i need more CPU power, ooo that C2D looks nice, and it's 775 just like my P4, ohh wait, doesn't work in my current 775 board.
Slashdot Mirror
have a list? that run on linux/OSX/windows?
i would assume that you could pick co-op or vs modes(in games that support that sort of thing).
depends on your usage, a shot list of typical for me; re-encode/stream video files to my ps3, World of warcraft, rip/encode of a dvd, emerge (yep i run gentoo), some sort of flash based music player(pandora+chrome is 17%-20% cpu). Seeing as all of those are rather CPU bound, WoW need GPU and IO as well, I'd love a machine with 32cores or so. toss 1-2 at the streaming re-encode, 2 for wow, 8ish for the dvd rip/re-encode, and say 3 for chrome. so thats 14-15 cores before emerge.

so what if my motherboard comes with onboard sound, and i buy a sound card? do i get double taxed?

do not plug in the computer and you'll be safe...
