TI-84+C-Silver Edition: That C Stands For Color

December 19th, 2012 12:32 admin View Comments


skade88 writes “Do you remember those large TI-8X line of calculators with a BW display from when you were growing up and learning all about math? Yeah well, you can still get them because TI has yet to update or change their line of TI-8X calculators from their 96×64 display, processors designed in the 1980s with just a few kilobytes of user accessible memory. They still cost in the $100.00 to $150.00 range. That is all about to change now that the TI-8X line of calculators is 22 years old. Their new TI-84+C-Silver edition will come with a 320×240 16-bit color display, 3.5MB of flash ROM, and 21KB of RAM. Ars has a good preview of the device along with speculation on why it took so so so very long for TI to finally bring calculators up to a level of technology that could have been delivered a decade ago.”Last month some photos and a few details of the new TI-84+C were leaked.

In Calculator Arms Race, Casio Fires Back: Color Touchscreen ClassPad

November 30th, 2012 11:38 admin View Comments


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?”

Self-Assembling Robots Using Flying Drones

November 5th, 2012 11:34 admin View Comments


mikejuk writes with an excerpt from I Programmer on a neat swarm of robots that use flying drones to build a map of their environment: “How can a swarm of robots get a global picture of its environment? Easy it simply sends up a drone. We are used to thinking of drones as being used for surveillance by humans operating on the ground, but what is good for humans is good for robots too. The drone can view the overall terrain and run simulations of what configurations of robots could best traverse the slopes. Once it has worked out how to assemble the robots into a single machine the drone has to communicate the plan to the swarm using a protocol based on the colored lights they all have. The ground robots adopt a random color and the drone selects the one it wants to communicate with by displaying the same color. They then repeat the process until only one robot has been selected i.e the drone follows the color changes of the selected robot. Of course if you don’t like the idea of human drones flying over your head you may not be happy about robots getting in on the act as well…” Original paper

The Periodic Table of Tech

October 26th, 2012 10:55 admin View Comments


itwbennett writes “From calcium in cameras and germanium in CPUs to selenium in solar cells. Here’s a look at how every single element in the periodic table is used in common tech products. For example: Scandium is used in the bulbs in metal halide lamps, which produce a white light source with a high color rendering index that resembles natural sunlight. These lights are often appropriate for the taping of television shows. … Yttrium helps CRT televisions produce a red color. When used in a compound, it collects energy and passes it to the phosphor. … Niobium: Lithium niobate is used in mobile phone production, incorporated into surface acoustic wave filters that convert acoustic waves into electrical signals and make smartphone touchscreens work. SAW filters also provide cell signal enhancement, and are used to produce the Apple iPad 2.”

Microsoft Patents 1826 Choropleth Map Technique

October 9th, 2012 10:04 admin View Comments


theodp writes “A newly-granted Microsoft patent for Variable Formatting of Cells covers the use of ‘variable formatting for cells in computer spreadsheets, tables, and other documents’, such as using the spectrum from a first color to a second color to represent the values in or associated with each cell. Which is really not a heck of a lot different from how Baron Pierre Charles Dupin created what’s believed to be the first choropleth map way back in 1826, when he used shadings from black to white to illustrate the distribution and intensity of illiteracy in France. By the way, beginning in March, the U.S. will switch from a first-to-invent to a first-to-file system of granting patents. Hey, what could go wrong?”

World’s First Color Moving Pictures Discovered

September 13th, 2012 09:09 admin View Comments


BoxRec writes “The BBC is reporting newly-discovered films made by pioneer Edward Raymond Turner from London, who patented his colour process on 22 March 1899.” When Turner invented his process, though, existing projection systems weren’t up to it; to see the discovered footage, British archivists digitized the film for computer playback. When you’re used to old films being both black and white and jerky, it’s amazing to see it in color and (relatively) smooth.

Forensic Test Predicts Eye and Hair Color From DNA

August 28th, 2012 08:30 admin View Comments


An anonymous reader writes “A forensic test that has been developed to help police nab perpetrators of crimes can predict a suspect’s eye color, hair color, and ethnic origin. The test’s ability and the science behind it has been outlined in Forensic Science International: Genetics (abstract). Developed by Susan Walsh and other researchers from the Netherlands, Greece, and Poland, the test uses phenotypes from DNA to … predict a suspect’s appearance using ‘low amounts of template DNA, as well as degraded DNA,’ which means that the DNA does not need to be perfect in order for the system to read it.”

Barnes & Noble Cuts Prices on Nook Color, Tablet

August 12th, 2012 08:20 admin View Comments


In perhaps one answer to the question of how tablet makers will react to a more crowded market for small screen tablets, the L.A. Times reports that Barnes and Noble is dropping the price on its Nook tablet by 10 percent, undercutting the Amazon Kindle Fire by $20. The company’s Nook Color is also shedding $20, and will now cost $149. I’ glad to hear it; I’ve been using a Nexus 7 lately, and finding the size (like a trade paperback, including a protective case) far handier and more often used than any of the 10″ tablets I’ve tried.

Predicting Color Blindness, ADD, or Learning Disorders From Game Data

July 27th, 2012 07:01 admin View Comments


An anonymous reader tips a story at VentureBeat about a company that helps game developers analyze data gathered from their games to detect cheaters. But now, the company says this data can also be used to determine other traits of the players, like whether they’re minors, or whether they like to gamble. Their CEO, Lukasz Twardowski, expects such analysis will soon be able to reveal even more traits, like whether a player is color blind, has a developmental disorder, or has Alzheimer’s disease. “‘Games are the richest and the most meaningful form of human-computer interaction. …By tracking how they play games, we can learn a lot about people,’ Twardowski explained. Hesitatingly, he added: ‘That will be a huge responsibility for us later on.’ … Academics have begun to take games more seriously, as a window into the human psyche. Games are addictive and immersive and are built to command hours of our time and attention. What better testbed for myriad psychological and medical conditions? A good game pushes us to our limits, challenging us to use both the analytical and intuitive sides of our brain.
