Well... show me one real application benchmark (like SAP or ORACLE apps., not TPC-C) where 10 one CPU machines has 9x times the performance of single of those same machines and I belive your speach. Currently, there's now paralell database that supports massive inserts using more than 2 nodes.
Clearly http://c-jdbc.objectweb.org/ looks promising, but there's still the problem of "order by" queries, since eahc node will answer its own order and the final appended result won't be valid.
Latency is the name of the game, with Ethernet in 10s of miliseconds and memory in the 10s of nanoseconds, there will always be a huge penalty for sincronization through network.
There's alway ways to add throughput (http://geocities.com/feromus/db-scalability.html) but latency will always have to increase...
Here http://wwws.sun.com/software/solaris/freeware/ you have a list of what GPL components are supported by Sun. You can buy a heap V210/V240/V100 that includes 1 year support and you will get best of both worlds (cheap GPL software big company support).
Actually, I wouldn't recommend Eclipse, unless you want to develop Windows only applications. The GUI API is created for every taget platform, so the final code wont run without modifications in other hardware than the one you used to create the program. So, you program in JAVA using Eclipse and lose the greates thing about JAVA, code portability!!
On the other hand, netbeans (www.netbeans.org) creates 100% portable code.
Looking at this story, I realize that there's lot of room for TiVO and TV in general to evolve. Simply put, instead of selling expensive set-top boxes for video on demand (VoD), just use a standar PC (with Linux encrypted filesystem inside some pretty case) that already has every single film you want to charge for. Whenever the provider wants to add a new film to the collection, he uses one channel to ftp (encrypted, of course, on DMCA's sake) them, and sends the corresponding delete list for the old ones.
I did my Goggle search and found the Norpak divice to extract data from a TV signal. The simplest way to charge will be a DirectTV style phone jack based approach. If the owner of the set-top doesn't send any report after one month, the provider will remove the unit from his house.
The great thing about this is that it works for regular air TV! Data Broadcast has a really good use that noone has ever explore... Regular TV should only be used for live broadcast, that's all.
Going on with the same idea, video streaming is a bluff. Just add the file in standar MPEG-2 format for everyone to download so they can see it at will. Once more, video streaming should only be used for live broadcast.
Well, at least for U$S239 you can get this http://www.electric-scooters-electric-scooters.c om/program/fixedPriceMod.cfm?do=detail&productID=66& categoryID=8 and it even come with a seat!!
Simply put, the more versatile Input device is the pen. With a Pen you can do everything you do with a keyboard, but no the other way around. You just can't draw maps with a keyboard, etc.
As far as I remember, the F-14 use to have a fluid computer in case of a nuclear explosion (mainly becouse of a Phoenix air-air missile lounched by the F-14), so if the EMP fried the computer, they still could fly the plane (althoug without any avionics).
Actually, 802.11b has better penetration at the same power, mainly becouse 5GHz iterferes with concrete walls even more than 2.4GHz
Maybe a microwave oven will force you to go as low as 1MB/s, but for sharing a ADSL connection (what I use it for) it is more than enough, plus I get the extra distance. 802.11a born dead...
If COBOL code is what bothers you, and you like Sun servers, check: http://www.sun.com/migration/mainframe/ind ex.html
I work for an automaker company (VW Mexico) and we migrate all our mainframe applications to Sun's UniKix platform.
The only hard part is 390 assembler code that needs to be completely rewrite. Fortunatelly we only hade few lines of it. COBOL code run with little change in Sun's E10000. It ends up been way faster and cheaper than the mainframe solution.
If your mainframe has 100 to 500 MIPS you will better try to buy the smallest Sun server that fits that computing power, to reduce even more maintenance costs. Maintanance for a E10000 was half of what we pay to IBM for his mainframe, too much for a Unix server if you ask me...
Sun claims that their new SF15K has 6400 mainframe MIPS... When IBM's G7 has 3000 MIPS. I don't now if that big difference is true, but a good Unix server seems to have comparable power to a mainframe at a lower price point.
The only big difference was the management of the Sun Server. Is not as "profesional" as it was for our mainframe. root account is own by to many if you asks me.. we did have some problems in the initial phase becouse of too many people doing to many things at the same time with root access.
What I really hate about Slashback is the "and more" part, it forces me to read on just to be sure I'm not loosing anything... Please post the full abstract!
The only problem for a serius big journal like NYT to post such an article, is that it has to mean it. As I'm writing this I'm using netscape 7.0 beta under Solaris/SPARC and the editorial page didn't load Ok, mainly becouse it surely was created using Microsoft products instead of W3C standar compliant products...
But besides from that, I really love to see NYT envolved in such a "Comunist" and "Anti-American" (as Microsoft talks about Linux) crusade. We need the support of the media (the 4ft power).
A nice follow-up would be an NYT editorial about getting rid of copyrights. C'ommon guys, there hasn't been no single significant advance due to copyrights. Penicilum wasn't copyrighted (as all new Penicilium based drugs are), Goedel's Theorem wasn't copyright (as PGP is), Relativity wasn't copyrighted (as GPS are), nor Cuantic Mechanics was copyrighted (as processors are). Only companies make money out of copyright, not people (not even companies employees, becouse all profit stays within the few owners).
I don't like his music, but Bon Jovi has just get a great idea to avoid piracy. If you buy his CD, you'll get a unique ID that gives you discounted access to his concerts, and many other goodies. Instead of defending a dying paradigm, he just adapted and find a new way to keep making money. I have to admit it, Rock starts can be smart (as amazingly as it sounds...)
Even for publishers copyrights are not needed. Simple get a contract with a big company that needs advertising, add it advertise as part of your novel/colum and allow it to be copied. The more it is copied, the bigger the reach of the commercial. The same goes to movies, add advertise inside of the movies, the more the DVD get copied, the better for the advertisers... or add discount cuppons for release 2 of the movie, or for the follow up book of the same author... there are plenty of ways to make money without copyright.
The problem is that Publishers has to be smart and not only find such new ways to get money, but to administer them properly (printing the right cuppons, honor them, etc.). Hard work, but feasable nevertheless...
Our father Benjamin Frankling didn't belive in copyrights.. and thanks to that we all are protected against lighting bolts and enjoy plenty of other of his inventions... And belive me, he was the only true American willing to give his life for the country, he just didn't wanted to let GREED OF A FEW GET HIGHER PRIORITY THAN THE WELLNESS OF THE MANY. As simple as that.
As you said, have Buffy pick a Mountain Dew is the best way to go. You can even allow unlimited copies of the show! Rip as many DVD as you want! You will be watching my adds.!
There won't be any need for DMCA any more. Copy everything you want! My advertisers will be very happy.
Sun's new Sun ONE application server has a free Liux version (I think it's in beta, but you can ask Sun for a copy). Although TomCat is a good implementation, Jboss is way faster. If you want support, go for the free Sun ONE application server.
As suggested (and denied) in Hofstadter marvelus book, do you think that Goedel Theorem affects the viability of a machine develping consciusness?
As a friend of mine says. Humans begin to fly when they stopped wraping their wings, and became aware of Bernouilli principle (when refering to neural-nets). Do you think that kind of understanding of consciuness can be developped?
The second best mpg car in the world is the A2 TDI. I need 2.8 litres per kilometer (sorry, I'm not a Yankee:)
The best car there is the Wolskvagen Lupo 3L that needs about 2.4 litres per kilometer.
Better than the Insight or Prius! Besides, you can use biodiesel!
As they already said, Knuth's "The Art of Computer Programming" is an absolute essential.
For JAVA, by far, the best book I read (and I have read A LOT of JAVA books) is "Just JAVA and Behind" by Peter Van Der Liden, Funnny as hell and great technical book too!
Just a book to understand why no system can be coherent and complete at the same time "Godel, Escher and Back" by Douglas Hofstadter. After you read it, you will accept that software will always suck.
This is simple, if you liked your original job, you should come to them BEFORE accepting the new one, and ask them to match the offer, then is up to you.
What you can never, EVER do is to stay, after you agreed on the new job, belive it or not, world is too small, and you will hurt A LOT your reputation, sooner or latter this will hit you back!
That's the mayor con.
Atherwise, if you haven't yet agree the new job do as you please!!
Well, Intel is doing it with Pentium4. I guess you are wright that the OS manages the threads, but in a multiprocessor systems you do have multiplethreads running. That's why IBM Power's shows as two chips for the OS, so they can be fetched a second thread. I guess that with a double register set (as the Pentium 4 does) you can publish yourself as two CPUs, althogh you really as only "one" (parallel Ok) processing unit, but keeps two threads states.
Yes, I did knew that... but hey, that's the point on showing what you want!
By the way, the SPECint for the Itanium are as low as I expected to be (less than half of the USIII or even the fastest Pentium 4!), that's why the will suck in OLTP. OLTP is marely int, and Itanium is only competitive (not the fastest) on fp, that's why the talk about DSS.
By the way, the tunning that Sun uses for the compiler, is only for SPECfp, it does not work on SPECint, so USIII is a real number, but of course you knew that, right?

Wouldn't it be nice if they GPL all the technology the EV1 has? At least the electric engines were supposed to be great...
Actually, SPARC would have been a far better option, since it's a 100% open spec paltform. The license cost just $99!!! Amazing..
