The story first says that the discs hold ~500MB of data, enough for one album. Then they turn right around and say that extra albums may be stored on the disc and later opened via some secure payment/key mechanism. It didn't sound like these things use compression (MP3, etc) but I don't see how they would be able to achieve this without some sort of non-raw audio encoding. Where is there more info on this?
And I thought I had a handle on memory technologies... The article speculates that MRAMs may eventually replace DRAMs, etc for main memory, but I wonder how feasible this is. It sounds like the manufacturing control has to be a lot tighter for these than for standard memories, so given equally stringent process won't DRAM yields be better? What other memory technologies are being developed right now?
Someone want to tell me how you make a digital speaker? Every design I know of involves magnetic fields, controlled by some wires that respond to voltages. When whoever comes out with fancy digital speakers all you need to do is rip out the digital wiring and viola, voice coil... Not that it would work at all afterwards with your SDMI compatible crud, but somewhere in there the signal is analog of digital quality...
It's waste money along the lines that war sucks and in a perfect world we wouldn't spend money on destructive anything, but the anology of ramming cars into one another isn't quite correct. More like me ramming my car into you so you don't see the angry mob around the corner going to burn down your house. Military Intelligence (insert well-worn jokes here) is becoming more and more important because fighting is becoming more and more tactical/strategic.
It is increasingly important (in their eyes) for the military to achieve their goals with as few casualties as possible. Look at the statistics at this school website for a rundown of American War deaths. For major conflicts the trend has been towards steadily lower numbers because the American people are less willing to stomach Americans dying.
I'm not trying to advocate some of the gross misappropriations of prior cabinets on space warfare, but you can't get something for nothing. I don't know how much a role space will play in 2017, but whatever it is America will have to spend some amount of money to at least stay aware of what other nations are doing...

CS vs CIS

· Score: 1
Not necessarily true. I did a BS in CS and I was able to fit in four semesters of Japanese, two semesters of photography, a jewelry course and a semester abroad in Australia. It required some extra work, but not unusually high course loads (~18 hours a semester). I think most schools have the flexibility to let you tailor your courses to a degree.
So, the X-Box has Nvidia on board, Nintendo's cube has a specialized GPU from, who, ATI? The PS2 has something similar. I know that consoles are usually sold at a loss, but how much of a loss? It seems that to get the right performance into a small box you have to have specialized hardware that would be comparable in price to this high end hardware. Even if they were using "commodity" PC parts, it would still be more than your bare bones home PC, and I certainly couldn't put something together for under $500 (Fast CPU,GPU and memory). Does anyone know how much a console really costs?
Carnivore? Last time I checked, that was an e-mail
sniffer. I'm not sure how that's going to stop a DoS attack unless the hax0rs who precipitated it are sending each other emails like:
From: hax0r d00d
To: tr0llb0y
Subject: I ki113d yah00!
"W00h00! I just d0wn3d yah00 from x.x.x.x, y.y.y.y, z.z.z.z and, oh yeah a.a.a.a. I am so 3133t!"
Well, technically DVD players are backwards compatible with CD players (I think it's a selling point), and I think the record companies are still making plenty off a CD it costs them, what, 50 cents to make when they sell it for $15...
Definitely. I was browsing around the local computer shop one day and I saw a two-cd set of UUW and UUWII for $15. Needless to say I snapped it up in a hurray. By far my favorite game. I think the Dungeon atmosphere probably helped constrain the play to a manageable level, but there seemed to be an endless array of actions you could do.
Again, the issue of poor security on internet attached machines is, I'm sure, well understood by most of those reading today. Unfortunately, the groups taking the most action (ie governement, big business) don't seem to fully fathom the mechanism by which these attacks succeed. I don't even know if there is a way to stop a coordinated DoS attack short of the traditional method of calling everyone who's spewing out traffic. With more sophisticated tools (that say, generate valid traffic) how would one differentiate between attackers and real clients? Short of adding more bandwidth I don't see any easy short term solutions. The fact that the government, particularly the FBI, thinks they can solve the problem by throwing money at it, performing wiretapping, etc, is frightening. Even more so considering that they're supposed to have met with Industry Leaders to discuss the problem.
I suppose my biggest fear is that the government would try to invent/incorporate some sort of master control system (super ICMP?) for IP. Not only would this likely be ineffective in deterring a serious attacker, but it would likely invite abuse as well. I'm not sure that our fearless leaders in DC comprehend the issues involved.
I believe the only way we can deal with this is the way it's always been done: as a community. It has been pointed out that a lot of the zombies in recent attacks have been Linux/Unix boxes. I know there are a lot of resources on the web for Unix security.RootShell, for example is a good site not only for descriptions of exploits, but actual code you can use to test your box. There is a lot of information about Unix/Linux security out there, but it's unlikely that any newbie will be exposed to it before during or immediately following the install of their OS. And we all know what kind of daemons get installed by default these days. I don't know if it exists, but a clearinghouse of security info, including not only alerts/exploits but instructions for newbies on how to fix problems would probably go a long way. Just raising the issue of security consistently (banner ads, links from most major linux sites) to this clearinghouse would probably be enough to get the attention of people who are working with Linux. Does something like this exist? If not, would anyone else be interested in setting it up? Perhaps it could be part of the LDP. Who knows. I'm envisioning far more than might be practical, but if anyone else is interested, e-mail me at po.cwru.edu, username dwb2.
A general purpose computer operating system is run using a real time operating system. A real time operating system is provided for running real time tasks. A general purpose operating system is provided as one of the real time tasks. The general purpose operating system is preempted as needed for the real time tasks and is prevented from blocking preemption of the non-real time tasks.
This looks a lot like a real-time Mach, or for that matter, a lot like QNX. Not that microkernel=realtime, but isn't that the basic idea behind a lot of RTOSs?
Hi, it's been a while since my 2nd year physics, but am I correct in understanding that the wave properties are a potential well (with the Cu as walls)? I'm trying to figure out how they could link any of these together. Wouldn't removing any of the Cu atoms destroy the well? Could they stack these in three dimensions, or in another vein, can the same Cobalt atom be used in different wells in different orientations? Does the effect require the surface that these atoms are deposited on, ie if you could just make a free floating ring of Cu would it exhibit the same wave properties (not that you could measure it with an STM)? I'm following for the most part, but I lost my quantum physics book in my last move and I'm looking for reference.
Nothing prevents Virgin from setting up kiosks in their stores that let you burn your own custom audio CDs from a catalog of artists.
Actually, the one in Columbus, Ohio has this. Pick your songs and it burns it for you. I was surprised when I saw it, but it was getting a lot of use. I think it was a little limited on the catalog, though.
Yeah, it's amazing sometimes. One of the guys in my Freshman dorm wrote his final project, a mule clone, with I swear 140 consecutive if-then statements. Last I hear he had the graveyard shift at an IHOP in Armonk, NY.
I went to Case Western Reserve University in Cleveland, home of CWRUNet. The entire campus is strung with MM and SM fiber to the desktop. 95% of rooms on campus have faceplates, including all of the dorm rooms. When I got there in '94 we had 10Mb Ethernet for every student on campus. In '97 we moved to 155Mb OC-3 ATM to the Desktop. When I graduated in '98, I went to work for the networking group at CWRU ('cause the GF was in the class below) and the few times I actually had to go out to the dorms to fix problems with PCs, people would actually grumble about bandwidth. Forget the Cable Modem and xDSL. With all of the residential fiber being pulled to A Block Near You(tm) I see at least 10Mb to the home within 5 years. Bandwidth is a commodity, and will soon be treated as such. D-rock
I guess it's technically a Head mounted display, but when I think of HMDs, I usually think of position/motion tracking sensors to go along with it (like for VR, etc...) Is there a different term for HMDs with sensors?
I agree. I got one of their "Mouse-in-a-box" (no kidding, that's the name) mice for $15. I like the ambidextrous design, since I'm a lefty. I have a really crappy mouse here at work because they only buy MS Intellimice, and it's designed for righties... If only someone would make an ergo lefty.
True, it's almost all research. Why waste the bandwitdh for people downloading crap from the web. I helped hook up a SGI Origin2000 to use I2 at the school I attended (and later worked at). The professor (materials science) was doing some massive calculations on thermal/fluid dynamics for plastic injection molding, metal forming, etc... He was using the Origin to render results coming back from a big NSF CPU farm. Keep in mind that the Origin had four load balancing OC-3 cards in it only because Fore dropped support of the OC-12 cards for SGI. This guy was moving many many Gigs of data across the network. Not something I'd try on I1...
