Submission + - In Calculator Arms Race, Casio Fires Back: Color Touchscreen ClassPad (cemetech.net) 2

KermMartian writes: "In what seems to be an accelerating arms race for graphing calculator supremacy between Texas Instruments and Casio, the underdog Casio has fired a return salvo to the recently-announced TI-84 Plus C Silver Edition. The new ClassPad fx-CP400 has a massive color touchscreen and a Matlab-esque CAS. Though not accepted on the SAT/ACT, will such a powerful device gain a strong following among engineers and professionals?"

Submission + - Stephen Hawking Claims 1st MIC Multiprocessor (sourceforge.net)

An anonymous reader writes: Stephen Hawking--the British physicist and cosmologist--claims his "Big Brain" supercomputer is the world's first shared-memory supercomputer powered by Intel's many-integrated core (MIC) architecture. Called Cosmos, the SMP supercomputers houses 32 Xeon Phi coprocessors with 1,856 cores in a SGI UV-2000 "Big Brain" chassis taking up five racks. Cosmos will be used to discover new planets and to answer other big-picture cosmology questions by the Miracle Constorium, which was founded by Hawkings and includes members from the most prestigious universities in the U.K.

Submission + - NASA: Rumors about curiosity incorrect (nasa.gov)

timmerman writes: "Apparently, rumors about major findings on Mars from Curiosity seem to be a hoax, as writes NASA on their website:
"Rumors and speculation that there are major new findings from the mission at this early stage are incorrect. The news conference will be an update about first use of the rover's full array of analytical instruments to investigate a drift of sandy soil. One class of substances Curiosity is checking for is organic compounds — carbon-containing chemicals that can be ingredients for life. At this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics.""

Submission + - Syria off the Internet Grid (paritynews.com)

hypnosec writes: Amidst the ongoing civil war, Syria has gone off the Internet a few hours ago with all the 84 IP block within the country unreachable from the outside. Renesys, a research firm, keeping tabs on the health of the Internet reported at about 5:25 ET that Syria’s Internet connectivity has been shut. The internet traffic from outside to Syrian IP addresses is going undelivered and anything coming out from within the country is not reaching the Internet. Akamai has tweeted that its traffic data supports what Renesys has observed.

Since i posted this article, we discovered many things: - The TI-84+CSE will have a z80 processor, same as the TI-82, TI-83, and TI-83+/84+ - It will have an Nspire-esque rechargeable battery - It will have a TI-84+/SE-compatible OS, so the same math books and lessons will work with it.

Submission + - Color-Screen TI-84 Plus Calculator Leaked (cemetech.net) 1

KermMartian writes: "It has been nearly two decades since Texas Instruments released the TI-82 graphing calculator, and as the TI-83, TI-83+, and TI-84+ were created in the intervening years, these 6MHz machines have only become more absurdly retro, complete with 96x64-pixel monochome LCDs and a $120 price tag. However, a student member of a popular graphing calculator hacking site has leaked pictures and details about a new color-screen TI-84+ calculator, verified to be coming soon from Texas Instruments. With the lukewarm reception to TI's Nspire line, it seems to be an attempt to compete with Casio's popular color-screen Prizm calculator. Imagine the graphs (and games!) on this new 320x240 canvas."

Comment Re:Kids interested in PROGRAMMING! (Score 1) 302

Absolutely agreed. I just wrote a book on learning to program using graphing calculators as a springboard, entitled "Programming the TI-83 Plus/TI-84 Plus", which ironically ships from the bindery to stores today! I heartily recommend getting kids excited about programming with graphing calculators, and in thirteen years of volunteering my time to the community I've seen hundreds of users become calculator programmers and later engineers or software developers. Sidebar: the LCD is 96x64, or 96x120 on the TI-86.

Actually, the TI-84+/SE have a USB slave port, which with some software bitbanging enterprising community hackers have turned into a host port for HID peripherals. So the USB keyboard/mouse with a calculator is a reality. Even the "dinky" TI-83 can be made to speak PS/2 with one or two KB of assembly code.

CALCnet allows networking of TI-83 and similar calculators with relatively simple external hardware.

With that detail out of the way, you are free to implement a display-wall and/or the most powerful z80 cluster computer in the known universe.

Extra credit, of course, will be awarded if you succeed in writing an xorg driver that can treat an MxN array of networked calculators as a greyscale display of appropriate resolution.

As the author of that hack, I solidly second that suggestion. We also have a bunch of other calculator hacking projects that might interest you, like case-modding, adding features likes backlights, PS/2 ports, a touchpad, etc. There was the FloppyTunes project ( http://www.cemetech.net/projects/item.php?id=38 ) that lets you play music on a floppy drive with a calculator. Since you have so many calculators, though, CALCnet would be fun to play with, and since we're always looking for people to help with a wireless version of CALCnet, that might be something fun. And no one has written a distributed computation system with CALCnet yet!
