theodp (442580) writes Electronics almost universally become cheaper over time, but with essentially a monopoly on graphing calculator usage in classrooms, Texas Instruments still manages to command a premium for its TI-84 Plus. Texas Instruments released the TI-84 Plus graphing calculator in 2004. Ten years later, the base model still has 480 kilobytes of ROM and 24 kilobytes of RAM, its black-and-white screen remains 96×64 pixels, and the MSRP is still $150. "Free graphing calculator apps are available," notes Matt McFarland. "But smartphones can't be used on standardized tests such as the SAT and ACT. Schools are understandably reluctant to let them be used in classrooms, where students may opt to tune out in class and instead text friends or play games. So for now, overpriced hardware and all, the TI-84 family of calculators remains on top and unlikely to go anywhere." So, to paraphrase Prof. Norm Matloff, is it stupid to buy expensive TI-8x milk when the R cow is free?

DeviceGuru writes "Variscite has unveiled what it claims is the world's tiniest Cortex-A9 system-on-module, measuring 52 x 17mm. The Linux- and Android-compatible DART-4460 board is based on a 1.5GHz dual-core TI OMAP4460 SoC, is available with up to 1GB of DDR2 RAM and 8GB eMMC flash, and can run at 400MHz on just 44mA. The module provides interfaces for display (HDMI, RGB, DSI), wireless (Bluetooth, WiFi), audio, camera, USB, and more, and it consumes as little as 5mA in suspend and 44mA while running from a 3.7V battery at 400 MHz, according to Variscite. And in case you were wondering, the iconic Gumstix form-factor is 12 percent larger, at 58 x 17mm."

DeviceGuru tipped us to the release of the latest single board computer from Beagle Board. It's been two years since the previous BeagleBone was released, and today they've released the BeagleBone Black (including full hardware schematics) at a price competitive with the Raspberry Pi ($10 more, but it comes with a power brick). Powered by a Cortex-A8, it has 512M of DDR3 RAM, 2G of onboard eMMC, two blocks of 46 I/O pins, a pair of 32-bit DSPs, the usual USB host/client ports, Ethernet, and micro-HDMI (a much requested feature). Support is provided for Ångstrom GNU/Linux, Ubuntu, and Android out of the box. Linux Gizmos reports where some of the cost savings came from: "According to BeagleBoard.org cofounder Jason Kridner, interviewed in a Linux.com report today, cost savings also came from removing the default serial port as well as USB-to-serial and USB-to-JTAG interfaces, and including a cheaper single-purpose USB cable. (Three serial interfaces are available via the expansion headers.) In addition, the power expansion header for battery and backlight has been removed."

An anonymous reader writes "Texas Instruments has struck back against Nspire gamers and hackers with even stronger anti-downgrade protection in OS 3.0.2, after the TI calculator hacking community broke the anti-downgrade protection found in OS 2.1 last summer and the new one in OS 3.0.1 a month ago. In addition to that, in OS 3.0.1 the hacker community found Lua programming support and created games and software using it. Immediately, TI retaliated by adding an encryption check to make sure those third-party generated programs won't run on OS 3.0.2." But if you want it, you can get OS 3.0.2 here.

CWmike writes "Texas Instruments on Monday announced it has agreed to acquire semiconductor company National Semiconductor for $6.5 billion in an all-cash transaction. TI, which makes low-power chips, said it would combine its 30,000 analog products and advanced manufacturing capabilities with the offerings of National Semiconductor, which makes analog integrated circuits. The acquisition is subject to customary closing conditions, and is expected to close in six to nine months, the companies said in a joint statement. Look out, [chip maker name here]?"

JoeBorn writes "VideoLAN has long been known as a mature open source project for video playback and transcoding on the PC. Now, Neuros and Texas Instruments have sponsored a port of VLC to their next generation open set-top box. The idea is to allow developers to easily create interesting plug-ins for recording and transcoding applications for the set-top box which will automate functions previously requiring a PC, like formating recordings for a portable player or streaming to another device on the LAN or the Internet, etc."

Karamchand asks: "Free Software and open standards are ubiquitous in the server and even desktop area. But why does nobody seem to care about openness in digital cameras? I couldn't find a single hint as to what main processor my camera uses (I guess many use ARMs and others use TI DSPs), and while searching for information about (re-)programming digital cameras, I had to give up (apart from the scriptable Digita OS which was used by some discontinued cameras by Kodak, HP et al). Do you know of any efforts in this direction, whether they are actual disassembling/programming of cameras or asking vendors to get more open?" I still have my Kodak DIGITA-based camera from several years ago and I loved the flexibility, even though the performance is poor by today's standards (long cycle times, poor battery life, etc). Why are digital camera manufacturers keeping the lid on the capabilities of their products, when digital cameras could be so much more than their film-based counterparts?

Bulldozer2003 writes "'Finally something both nerdy AND sexy engineers can do.' It sounds like an oxymoron but this guy took a cue from The Vos Pad and decked out his own dorm room bed with Light Emitting Diodes. They're even fully adjustable 'allowing me to create every color of the rainbow.' Total cost, according to him in an email: 'Around $25, the LEDs cost me about $0.25 a piece in bulk, and the potentiometers cost about $6 a piece from digikey. I got the LM317 voltage regulators as a free sample from Texas Instruments. Lots of companies will ship you free samples, its a good deal for college students.'"

grey writes "The Age has a story up about how the OpenBSD community has been contacting wireless chipset vendors to license their firmware binaries under terms that would allow for free redistribution. This is important, because even with existing GPL and BSD licensed drivers for these chipsets, the drivers don't function without first loading onerously licensed firmware binaries which can only be acquired from the vendor, not shipped by an OSS provider." (Read more, below.)

In just the first 4 days, hundreds of users wrote and called vendors, and already 2 vendors freed their firmware, and several others are in discussions with Theo de Raadt about taking similar steps.

We need your help! TI has still not responded at all. You can call or write to Bill Carney, - Director of Business Development of TI's WNBU to add to the approximately 400 well written messages the OpenBSD community has already sent to TI.

PowerVegetable asks: "What's the story with handheld computation? Not address books and schedule reminders; I'm talking about the type of stuff computers were invented for. Anyone who's used Mathematica or Maple knows what desktop computers are capable of these days math-wise, but handheld computation seems to have fallen behind on the innovation front. Cell phones and handheld game systems have certainly enjoyed rapid advancement, so where are the handheld mathematical portable oracles? What's available that doesn't have obscure menu systems, bad displays, underpowered processors and unwieldy programming languages? Pickings are slim in the hard-coded calculator industry, but what about Pocket PC's or other programmable portables? Is there any portable solution out there that's more capable than my old HP49g?"

VernonNemitz asks: "Light-Emitting Diodes (LEDs) have been around for decades, and they come in all colors. Here are the basic principles behind their operation, information on what's currently in production , and other practical info. Now, you would think it obvious that video displays should be made from LEDs, to take on the various competitors. Certainly this has been done on a large scale, and I am not the first to be interested in LED display technology for home viewing. The apparent goal of silicon LEDs these days seems to be tied up with optical communications between circuits, have they forgotten the possibility of making high-resolution display panels?"

"Achieving a good image will require smaller pixels, and now I have a better understanding of what has been holding it up, so would like to share what I found out. Basically, unlike a lot of electronic technology, LEDs are mostly -not- made from silicon. So, while silicon diodes are common, and large arrays of them are also made (for sensors), LEDs are not easy to incorporate into standard integrated-circuit manufacturing. Nevertheless, researchers have been pursuing and steadily making progress toward integrating silicon-based LEDs. Even whole arrays, 'suitable for large two-dimensional areas', of silicon laser LEDs have been made, as far back as three years ago."

S. Kinney writes "TI recently announced the development of a new calculator, known as the Voyage 200, to replace the TI-92+. The software changes are rather minor, as the device is designed to be compatible with the 92, though the addition of a clock makes the Voyage more functional for some, and the case of the device enjoys a new design. Perhaps the most useful upgrade to the 92+ is the addition of more memory, for a sum of 2.7 MB of storage. No word on release date, but it'll be interesting to see how this comes out. It may be one more step towards releasing a modern-day Avigo, their failed PDA from a few years back. "

For tonight's Slashback, eaders have submitted updates and corrections tonight on several recent stories, from the global raid on illegally copied software to ever-more software for your TI-89 to the confusing names (and ownership status) of Mexican banks. Read on for the details.

Many happy returns! Eileen Gunn writes "Last August, Slashdot ran a story about The Infinite Matrix, an online SF zine aimed at technogeeks, that posted its first and last issue in one fell swoop, after losing its funding (what's new?). The site was slashdotted, of course, and among those visiting it was a Slashdot reader who threw the zine a 6-month financial lifeline. The Infinite Matrix is now posting new material every day from both Bruce Sterling and Terry Bisson. Plus, there's a new story by SF giant Avram Davidson, more fiction by Richard Kadrey and Kathleen Goonan, columns by John Clute and David Langford. Thanks, Slashdot! You've made my life infinitely more complicated."

This is like reading Jules Verne when he was writing newspaper serials -- and no eBook reader is required.

The perils of translation and the world of international banking. Al Giordano of Narco News wrote from Cochabamba, Bolivia, with a correction of my (incorrect) correction on Yesterday's post about First Amendment protections granted online journalism. He provides a better explanation about nomenclature and the Mexican banking system:

"Banamex, or Banco Nacional de Mexico (the way the plaintiff's name appears on the now-dismissed complaint against us), is translated as National Bank of Mexico.

The 'Mexican Fed' that you refer to is titled Banco de Mexico, or Bank of Mexico.

So you got it right the first time!

The confusion stems from this: All Mexican banks were nationalized before becoming privatized. It's a long and bloody story and in fact my own story about it is one of the exhibits used by Banamex in its now-fracased SLAPP suit.

When Banamex filed suit against Mario Menendez, Narco News and me, it was still a Mexican bank. The Citibank merger wasn't announced until May 2001 and wasn't finalized until July 20, 2001, ironically, the same day we had our court hearing in New York."

Unfortunately, there's no monopoly on sketchiness. S^(2) writes "Here is a better rundown of the warez crackdowns across the globe.

That can't be legal, can it? Should I hide my pc behind a wall of something benign, like say VHS bootlegs?"

My idea is to have the a display projected on the windshield, from over the left shoulder, displaying realtime IR images, possible hazards, and GPS location, at a low lumens level, and for the unit to have small power requirements / low heat waste. Resolution is not that important, 800x600x16bbp is ideal, but I'd settle for even for 640x480x8bbp. After searching a bit, I found the DLP units from Texas Instruments. Be sure to look at the DLP image library too. Are there any other projectors like these?"

After looking at some from TI and others from HP, I've got one question: Which is the best for a geek? The TI is pretty much the education standard, but HP claims to have some great calculator programming stuff. (They call it the Most Programmable Calc out there.) So should I go with the flow and get a TI, or should I get an HP and have a little fun with it? Any suggestions?" Are TI and HP the only ones out there doing graphing calulators? If not, who else in the market makes some decent products?

If no software exists at this point, is someone working on reverse engineering the protocol?

ajalics asks: "I need a program to transfer files between my Linux box and my TI-86. TheTI family of graphing calculators use an 1/8" jack to a serial port called a TI graph-link. Unfortunatley TI only provides Windows, Mac, and DOS software. Does anyone know of any Linux software that will let me talk to my TI?"

Andy writes "TI has created a new IC called the DLP (Digital Light Processor). It contains thousands of tiny mirrors, one mirror assigned to each pixel in a 1:1 ratio. It uses another of their technologies called DMP, Digital Micromirror Device. It is capable of producing 16.7 million colors and projecting over large distances. The quality is supposed to be much higher than that of LCDs, and the chip itself if extremely small. It is supposed to produce a perfectly clear "A" the size of a dime at 20 feet. "
