Airbus thought of that: It's called Abnormal Law. When the plane finds itself in a condition that the fly by wire system wouldn't have let the plane in, hard limits are disabled automatically.
Your idea is sort of like Vector Quantitzation, where both sides have a table of most likely sequences and is used as your constant. Basically you compress not only with the file, but with every other file you might compress.
Unfortunately, Yamaha tried this with TwinVQ, and it didn't work. Slow and low quality. There's speculation that a modified form is behind WMA, which works surprisingly well.
Inclusion of watermarking code into DSPs is inevitable.
Well, a DSP is a microprocessor which likes to add and multiply for real-time applications. I would expect a DSP to be able to watermark as much as an Athlon can. The impressive thing is that they're students and now I have an extreme urge to incorporate a TMS320C5410 in my car's ABS system.
Has anyone else noticed the amount of junk mail comming from TI is extremely high? I ask them for one data sheet and I get seminar invitations and catalogs in my mail every day...
Nope. Iridium was delayed becuase one of the ground stations was in Canada and the Feds wanted to be able to tap it. I think they made arrangements for remote access.
Also, the Chinese government has control of the airwaves in China. If Iridium doesn't have a license, they can't operate there. They must make concessions to make the government happy. I believe that Iridium blocks access from countries that haven't issued licenses. That's also why satellite communications prices are so high--- to satisfy countries with state-owned telecom monopolies.
If you want unlimited data and don't care about the satellite access but need more coverage than Ricochet, Bell South's Mobitex network has unlimited plans around $50/month. You can use a radio modem, or like me, use a RIM 2-way pager. It's popular for trucks and other embedded systems. IIRC, its about 9.6 Kb/s
If you need satellite access Orbcomm had the first LEO satellite constellation. I think in some areas, satellites store the messages until they are in sight of a ground station, so its not completely real time, but works just fine for trucking and remote sensing apps. In fact, some oil fields are controlled via the network.
The sievert is m^2*s^-2 which can be written as J/kg, so it really doesn't count.
Besides, a becquerel is really a radioactive disintegration or tranformation per second and a hertz is a cycle per second. We can't measure traffic flow in hz or bq because its cars/sec. 4/sec is not a valid convertable measurement.
It is the closest equivalent.
I have a friend who, lets say, drank a bit too much Ethyl Alcohol. Most people, when drunk, seem to drive cars, pursue initimate premaritial sexual relationships, or get involved in criminal activity.
The first thing he thought of was to play Counter Strike, even though he couldn't make his player walk in a straight line. Nobody could drag him away from it and was pretty hilarious.
Solaris slow? I've always heard that Sun boxes were the best at IO. Of course, that's a combination of hardware & software. I thought it was pretty fast on my Sparcstation 20, but that was back in Solaris 2.4. Has Solaris gotten slower and bloated?
The number one non-clustered TPC-C machine is a Fujitsu Sparc/Solaris 8. Sun has the second most computers in the Top500 list. Large clusters and mainframes are high profit margin systems and don't need pretty pictures. If Solaris on small comptuers is getting slower, perhaps Sun is perparing to leave the workstation market, which is a shame.
I honestly don't care about whose processor or other piece of hardware is faster. Without software, that hardware isn't going anywhere. I don't buy computers based on what _may_ happen or theoretical performance gains that can be realized in the future, 'cause those don't mean a thing.
I buy state-of-the-art computers to run jobs that need to be done _now_. Therefore, performance of the system must include the performance of current compilers, even if they don't play nice with AltiVec, 3dNow Pro, Jazelle, or MIPS-3d.
I do fall for marketing propaganda for my personal computers, but emacs and LaTeX is all I really use.
If I were to make a competitor to this device, I would buy a 20 Gig hard drive and make some fancy plastic external removable drive bay. The first thing I thought of when I saw this was "Hmmm... Hard drives are cheap. I wonder if Iomega is exploiting this fact".
I think the _real_ problem with this product is the ease at which devices can be connected or made to work. In order to connect a keyboard or mouse to the base, you have to press a button on both. This leads to countless pranks reprogramming somebodys keyboard to another nearby base station and leaving the Win2k login prompt up or whatever.
A password or some other user authentication before reprogramming/key exchange would be nice or even making the connect button accessable only by paperclip would help (a little). I rather my money protect me against silly roommates rather than the NSA.
I think, by the way its designed, each base station normally will only accept one keyboard and mouse. Therefore, you'll have to do more than buy another keyboard.
What these keyboards _really_ need is a system to authenticate the keyboard and receiver. I know two roommates both with Logitech cordless mice/keyboards. The base station is normally limited to only one mouse/keyboard but a keyboard can transmit to any number of base stations.
To use a device with a base station, you hit the connect buttons on the base and the device. This leads to a constant battle of device substitutions. When one of them leaves Win2k at a login with their username saved, the other roommate reprograms their base station to receive the keyboard and gets the password.
I think security against attack by silly children is more important for this product than protection against the NSA.
A Beowulf cluster of these would be quite silly. The main selling point of the z900 is that it is massively partitionable. It puts the Compaq/Digital GS320 and Sun Enterprise 10000 to shame. If you're running just one application or computation, partitioning doesn't serve a purpose.
The z900 is designed for insane availability (It's relative, the G3, runs the US air traffic control system). Features, such as partitioning and the impressive Dynamic CPU sparing ensure that the computer is always running at full capacity. These features are not necessary for scientific clusters and defeat the purpose of Beowulf's impressive price/performance ratio.
These people should go run AIX. My first computer, 11+ years ago, was a brand new RS/6000 and it was in use until very recently.
AIX is, in concept, more advanced than Linux and other Unicies. IIRC, it has a large protected data structure that stores system settings (a.k.a. registry). All admin could be done through one program, the SMIT.
The hardware was crap though. IBM decided to initialize video last, or close to last. Therefore, a 3-digit 7 segment LED was installed on the front, which blinked numbers for 10 minutes during boot. It makes sense only for headless servers. You never want to deal with IBM's techs, especially those who worked in our "small" city.
I'm looking forward to AIX 5L on Itanium.
I've heard the DEC Multias get pretty hot too and sometimes overheat, but I think it has a lot to do with large hard drives and RAM people put in, beyond their original design.
Wow. It appears you don't run a server with a large storage array, a SAN or most types of cluster.
Actually, nobody needs Gigabit. What we need is Fibre Channel (which has TCP/IP capabilities too).
Note that both Fibre Channel (and its relative Gigabit Ethernet) use copper for short-distance interconnects. It's cheaper and by using signaling techniques such as Gigabit's PAM-5, you can get pretty impressive data rates over copper. Although these are really long(er) distance connections and we probably want short-distance interconnects, the same idea applies.
The SGI Origin 2000 and 3000 distribued supercomputers have processors, video boxes, pci boxes, and storage in different racks. They use a huge copper cable and have aggregate bandwidths of up to 716 GB/s.
(The manual for the 3000 also warns not to turn the power switch on or off by yourself. You must have a field service engineer do it for you)
AGP 1x based on 66 MHz, 32 bit PCI with additional features such as textures in main memory. Bus arbitration was removed to improve latency, which is why its a port, not a bus.
