Yes, I've measured it. Windows does cache writes, but the cache is filled very quickly due to the MLC flash coming to a screeching halt on small writes. I've found the cache to fill in less than a second.
They weigh less. The weight consists of a single circuit board and the flash / controller chips soldered to it. Subtract the motor, magnets, spindle, bearings, and disks themselves.
The Intel drive uses MLC and while its write speed might appear competitive, the relatively large block erase that happens with MLC will make this drive impractical for typical "system drive" usage. Small writes will bring this drive to its knees.
Many of the modern SSD's *DO* saturate the bus. The Memoright GT and other SLC flash drives easily push 120-130 meg/sec over sata 150. The key is that the 'cheaper' MLC based drives have horrible write speed, especially when writing bunches of small files. Most users think this won't bother them, until they realize outlook does exactly the same thing when accessing its PST.
The thing I don't get is why so many people think SSD's are slow. Even MLC based first generation samsung PATA SSD's obliterate even the fastest laptop hard disks in all areas except for the aforementioned small writes.
From my own desktop testing, a single Memoright GT completely owns the pair of raid-0 74 gig raptors it replaced.
Chapter 1 covers electrical, chapter 2 covers electronic. The remaining chapters dive into nuclear power field topics (chemistry, mechanics, reactor theory - also very handy for those interested in 'just the facts' for those topics). This reference is about as technical as it gets without venturing into "If I told you I'd have to kill you" territory.
It's awesome that the Naval Academy has an unclassified version out there...
ABS does shorten stopping distances on wet or snow covered roads, but if the road is dry, the stop time will be much shorter if the wheels lock and you skid.
Actually, this is not correct. The Bosch Automotive Handbook has graphs on this, but I could not find them online. A very similar graph is found here. Notice the black line, which represents acceleration/beaking force. The X-axis of that graph is the slip ratio. From the graph you can see the highest braking force comes from a relatively low slip ratio (~5%). The force quickly drops after passing this ratio. Therefore - locking up the brakes will _not_ give you better braking than keeping the slip ratio at the peak braking force area of the curve. Also see threshold braking.
Winrar already does this from within windows explorer. Select the group of zip files and do a right button-drag to wherever you want for the destination. Select 'extract here' from the menu that appears when releasing the right mouse button.
i work on submarines for a living. if we (the crew) were to do poorly under pressure, we would (literally) compress, and yes it would be messy. what to take out of this is that from what i've seen, even those who would normally crack under pressure, when put into an environment where that would lead to a very bad outcome (death), generally do much better under those high pressure situations.
well, this is the extremely long way around, but it did happen...
while i was out at sea, the wife once saw something on slashdot that she figured i would like. she included a snip of the article in a familygram (these are hand-written messages, mailed out to the submarine base). these messages are then transmitted out to the submarine fleet, where each sub grabs their respective messages, prints them, and passes the messages out to the crew.
so, i have (very indirectly) read slashdot from somewhere under the Atlantic.
replying... is a different issue entirely.
wait a second, 'transmitted out to the submarine fleet', hrm, it appears my wife/.'d most of the Navy. i'll have to congratulate her on that one.
i agree that avant is good, but i recently tried most of the ie-based browser apps (this was due to the netcaptor author deciding to totally drop the product development after a supposed final (cough-buggy-cough) release) this definitely sucked, considering i had just paid for the regged version (silly me).
anyhow, i shifted to avant, which was cool, but it was annoying because it couldnt do simple stuff like remember the order of the tabs when you closed / reopened it.
then on a hunch i tried out myie2(.com). it is free, like avant, and has equal development pace, but all of those 'little' things that should be in avant have actually made it into myie2. avant was missing some simple java based content filter stuff, but myie2 worked fine filtering the same content. also, i've found that myie2 uses less resources and just seems quicker overall.
anyhow, its definitely worth checking out if you're among those who stick with windows (for whatever reason).
The CONTOUR Board concludes that the probable proximate cause for loss of the CONTOUR spacecraft was overheating of the forward-end of the spacecraft due to base heating from the SRM exhaust plume. The CONTOUR SRM nozzle was embedded within the spacecraft to a greater degree than is typical (Fig. 3), and the resultant near-field effect of exhaust plume heating was not adequately accounted for in the design. Overheating may have caused substantial material weakening and structural degradation, which could have led to catastrophic dynamic instability.
...that i believe people will simply start ignoring it altogether. for example, i'm building a twin engine vw scirocco. i am coming up with my own engine management, suspension (active) control, and just about everything else (its a personal eduaction project). you might figure some patents may be in order depending on just what comes from the project, and i know it would be incredibly easy to be granted such patents (especially nowdays)... however, i find the current system such a load of crap that i believe filing for patents may do more harm than good, especially once people begin to place no regard on the protection that the patents once stood for. with people filing for totally obvious stuff like how to swing on a swing, how can you possibly expect anyone to take the system seriously?
...also uses the master/slave relationship when referencing data transfers between system cards in the system. It is a very widely used standard in various control systems (even the Navy uses it). The Navy teaches these systems in their schools (and uses "master" / "slave", btw). There are literally hundreds of books currently published about this specification. Whats next - removal of the 'offending' references from their libraries? These jokers should really do even a tiny bit of research as to the results of such a change, PRIOR to making that change.I see this as one of those laws that is so rediculous, it is ignored by everyone, further taking away from the image of the legal system.
unfortunately this is not always true, as the cable node is usually powered from the neighborhood power grid, where the phone system uses its own seperate power source, even at its nodes.
This is freaking crazy. Quit blowing every little thing out of proportion. Allow me to elaborate:
Say someone is a great locksmith, and he breaks into your house, snoops around, reads private information that you have locked up in your cabinets, and then uses your phone to make a bunch of long distance phone calls. Should this person be held liable, even if they are willing to give you, for free, a "Brand New Burglar Detection System"?
Lamo did the equivalent of opening the front door (which can almost be said 'unlocked' in this case), and left a note on the floor saying "lock your door. if you're having trouble locking your door, i'll help you fix it".
If someone breaks into my car and crashes it into someone's house, I shouldn't be held liable, he should. Just because I left it unlocked (or locked it, but didn't use the Club) does not make me culpable.
Lamo did not direct the NYT servers to cause damage to any other servers. Actually, Lamo didnt even do damage to the server he had access to.
But it seems like they're doing fine now, especially since they were so open about their mistake and showed a willingness and intent to improve.
Yeah, this is called PR, every company does it, and does it well, or they go under.
If Adrian is such a great damn hacker, why doesn't he just go straight to the corporations and say, "Look, I know that I can hack into your system. How about you pay me to make it more secure."
Because they (and many corporations like them) would most likely laugh in his guys face. If it was really as easy as you say, all hackers would be employed right now, and news stories like this would never happen.
Unless someone gives you PERMISSION to break into something of theirs, IT'S ILLEGAL TO DO SO.
END OF STORY!
Fine, lets all just quit worrying about computer security. I mean, we have nothing to worry about, right? NOBODY in their right mind would do anything ILLEGAL... its against the law! Why i'll go take the lock off of my front door right now.
Face it, NYT had sucky security practices and Lamo prooved it to them. They should be thankful. It could have been someone else with much worse intentions.
I'm still floored that NYT is actually claiming damages. The system had crappy security, and he showed them. NYT were the neglent party. Their business model almost appears to be...
1. Blow off security issues. 2. Wait for someone to show you your system sucks. 3. File huge lawsuit, claiming damages that are actually the cost they should have paid themselves. 4. Profit (its apparent here, since Lamo is now the one who will cover these costs).
so why doesnt that kazaa maker (the one who just got kazaa-lite links banned from google), sue the RIAA based on their violation of the DMCA by reverse engineering kazaa to show the IP addresses of the connected users?

That's about as 'just the facts' as you can get, which comes in handy from an adult learning / slashdot-oriented user perspective.
Hope this helps...

IIRC, that was specifically referred to as "vocaltec internet phone", and not "iphone".

mIRC is scriptable. once the standard is set, it would take only a short time to implement into mIRC with an easily installed script.
