TI vs. Calculator Hobbyists, Again

Posted by timothy on from the p0wning-the-market's-not-enough dept.

Deep Thought writes "Texas Instruments, already infamous thanks to the signing key controversy last year, is trying a new trick to lock down its graphing calculators, this time directed toward its newest TI-Nspire line. The TI-Nspires were already the most controlled of TI's various calculator models, and no third-party development of any kind (except for its very limited form of TI-BASIC) was allowed until the release of the independent tool Ndless. Since its release, TI has been determined to prevent the large calculator programming community from using it. Its latest released operating system for the Nspire family (version 2.1) now prevents the calculators from downgrading to OS 1.1, needed to run Ndless. This is TI's second major attack on Ndless, as the company has already demanded that websites posting the required OS 1.1 remove it from public download [PDF, in French], obviously to prevent use of the tool. Once again, TI is preventing calculator hobbyists from running their own software on calculators they bought and paid for."

    I understand for some occasions (tests, etc) it has to be a calculator, but I doubt it would be allowed to run modified software.

    Which represents a TREMENDOUS market for TI, one that they are not going to give up on so easily. You may doubt that modified software will be allowed, but nobody is looking at checksums before you enter a testing room. The assumption is that you have not modified your calculator, and if that assumption is shaken, it will mean the end of a lot of calculators for standardized tests. If I were to try to guess why TI is fighting these hackers, I would say that it is all about the standardized tests, where TI calculators are exceedingly popular.

      I graduated in 2004.

      Funny enough, in my university there were ZERO TI Calcs, we would all be in HP48/HP48+ and beginning to see the 49s... (not in US, as you may have guessed)

      But I've seen TI calcs (in France), people would use TI-92s and entry-level models, still, there was one HP48 in my class there.

      Makes sense... Still, I'd guess they would ban the 'fancy' calculators.

      At the same time, people would not check the fact that some people had entire tests solved on their 48G+ (I had the 48G)

      My HS math teacher spent her spare time designing her tests carefully so that no calculators were needed. If you got down to the end of a question, and you had messed up and ended up with something that *would* need manual calculation, you didn't have to work out the calculation--you'd just lose the point(s) on whatever theoretical part you screwed up, and that was it.
      No calculators were ever allowed---nor were they needed.

      I learned one hell of a lot of math.... including vector calc and laplace transforms senior year (finished ap calc bc junior year along with 11 other kids, so that teacher wrote course material for a calc 3 class).

  2. I thought TI had seen the light... by yeremein · · Score: 3, Interesting

    When I was in high school, Zshell (an exploit that allowed running native Z80 assembly on a TI-85) was all the rage. The exploit and various apps (mostly games) spread virally throughout the school. I did some Z80 assembly programming myself, and it was a learning experience arguably more useful to my career than anything I learned in high school...

    Years later at college, when my old 85 had been handed down to a younger sibling, I found I needed a graphing calculator for a physics class. I bought a TI-89 and was impressed to see TI allowed it to run native software, no hacks required. (There were still hacks, to get around a few limitations such as code size, but even these limitations were relaxed in later firmware versions.) I spent far more time programming the calculator than actually using it as a calculator.

    Now they're back in their lock-it-down mode? Shame. It always disappoints me when manufacturers go out of their way to make their devices less useful--and in this case, a less capable learning tool, for budding programmers anyway.
