Shutochnaya biografiya yubilyara. To United TI, a group of enthusiasts. They had been cracking the keys that sign the operating system binaries in an attempt to gain access and possibly expand on the features. This seems, at least a little counter productive to us. Texas Instruments doesn’t sell the operating system separately do they? These people were buying their product and expanding on it.

Maybe they are charging more for an expanded feature set that is crippled in the OS. [via ] • • • • Posted in, Tagged,,, Post navigation. This article lashes out pretty bad against TI.

Please keep in mind what they have to lose here. It’s not about keeping software proprietary. It’s keeping their calculator OSs standardized so they can keep their approval for national tests such as the ACT/SAT. A TI-89 is not allowed on them, but if some hacker can force an 89 OS onto the 83, then that would mean the TI-83 couldn’t be used either. I’m all for hacking something, but TI stands to lose their entire market share because of this. Keep in mind your ethical responsibilities. Hackers have it too.

A site like hackaday should hold it in much higher regard. Some colleges let students use graphing calculators during testing? My profs wouldn’t even let us use our own scientific calculators – we were always given scientific calculators to use during tests. In high school, though, we had all kinds of tricks to hide files and programs so our teachers wouldn’t notice them if they checked or tried to wipe our TIs, but nothing that could be considered a “hack”.

If schools are concerned about cheating with graphing calculators, they need to prohibit them entirely. Charper, I have no ethical responsibility to ensure the income stream of Texas Instruments. However, I do have rights of ownership over property that I purchase legally. The DMCA here is used as a club to attempt to force individuals to keep from tinkering with hardware that they are the clear owners of.

TI cares not whether the individual has rights to modify their own objects. They don’t even seem to care that this type of hardware “hack” is not covered by the DMCA. Their sole point is to use threat of legal action to prevent legal behavior. I think it’s TI that should worry about it’s ethical responsibilities to not sue your customers frivolously just to retain market share.

At my college we are allowed to use graphics calculators during the exams and even on some all the notes and books that you’d want. -All these are useless and you only will lost your time- you need to have learned what they are asking and know how to do it, and quickly! Never will be able to finish it no mater how well you know the matter, and I’m quite sure that neither they will. If a calculator will make the difference, then these tests are really bad and certainly isn’t meassuring what you know and what are able to do. It was possible to load machine language programs, store all kinds of data, notes, etc in the TI-85 a dozen years ago. That knowledge wasn’t new back when I was taking standardized tests, yet the TI-85 was not banned. The proctors sometimes wouldn’t even bother wiping the calculators before the test, so I’d play Jezzball after the test was over.

But I never needed to store cheat sheets in the calculator anyway. The point is, someone could, and it didn’t affect the testing rules. You just weren’t allowed something with a QWERTY keyboard. They don’t care about you taking something IN, they don’t want you to sneak the questions OUT! There was a scandal a couple years back when some kids on the east coast were sneaking questions out for kids on the west coast.

If a math test is easily defeated by a calculator, they’re testing incorrectly. My Calc teacher in highschool allowed us to bring whatever we wanted for tests. Of course, the test didn’t actually use any numbers, so a calculator was zero help. Same thing was true in college, in the beginning of diff-eq.

Then, about half-way through the course, the professor said “And now I’m going to teach you how to use your calculator to do everything you learned”. Thank god for eigen vectors in the TI-85.

PS: I still have my working TI-85, that just turned 15 years old. “Maybe they are charging more for an expanded feature set that is crippled in the OS.” This is exactly what they’re doing. I go to school at UT Dallas, which is right down the road from TI. Some of my instructors have held top-level positions there. I specifically remember one talk about economies of scale and why the $10 calculators have the same chips as the higher end ones. Chip fab requires a massive investment, so it’s more economical to make one chip for everything than design, build, and test a whole line of chips. I am graduating college this Qtr.
