Note: I have paraphrased the French to English translation in order to make it sound as coherent as possible. what has allowed Planète Casio and TI-Planet to point out to manufacturers several annoying flaws concerning the exam mode, without exposing the national exams to more cheating. The potential circumvention of the exam mode is. in the short term, exposing the vulnerability has only spread it and increased cheating. I think forum Planet Casio explains it better than I can:Īlmost all calculator models have flaws allowing cheating to varying degrees, and many are vulnerable to modification of the hardware or the LED. It's also infuriating that TI's consistent reactions of killing a fly with a sledge hammer has done nothing to solve their security, in fact it has only worsened it. Forget about gLib, how can anyone be expected to write a simple ray-tracing or fractal script on-calc when it'll take nearly half an hour just to push the pixels out? Even when using TI's proprietary ti_graphics primitives it's still several times slower than the competition's put_pixel(). The next two best calculators are 100x to 200x times faster. TI-Planet clocked the put_pixel() fill rate at 48 pixels per seconds. Graphics performance in particular is simply atrocious. From TI-Planet's numbers, just about the only calculator that's roughly as slow is a Casio Graph 35+E, a monochrome calculator, and only mostly on integer benchmarks. It's the slowest Python implementation in a calculator. TI does offer alternative programming options like TI-BASIC and Python, but as TI Planet user jean-baptiste boric points out on Cemetech: TI Planet's time trying to protect the community isn't the only thing wasted, the hundreds developer's countless hours spent creating amazing content from overclocking utilities, to math additions like CAS, and games will become obsolete when newer calculators inevitably outnumber older ones. TI Planet has put so much meticulous care into protecting the hobby of thousands of students and future Computer Science Majors, like me, it's infuriating to see one clumsy video with a quarter of a million views set years of hard work go up in smoke. TI-Planet, has privately shared security flaws related to Exam Mode TI needed to fix, and kept vulnerabilities a secret as to not cause this exact situation. Then when release date came, they pulled the rug from under our feet and released OS 5.5.1 instead which did include the ASM restrictions To the community, it looks like TI knew we would hate the removal of ASM and therefor gave a different build to us just to drum up support. This build given to TI-Planet had all the benifits of the new Python abilities, however ASM was not banned on this build. This is quite a punch in the gut for the community, TI had given TI-Planet (a very reputable TI forum that has been reporting on calculator news for over a decade) a beta build of OS 5.5.0 to review and post about. What made the matter worse is they passed the issue off as if it were still present in modern OSes! With the video gaining almost a quarter of a million views, TI thought they'd need to take some drastic measures to uphold their Exam Mode security reputation. One big factor in the decision to ban ASM was due to a video created by a student and a teacher that showed the exact steps to bypass a Test Mode restriction in OS 5.2.2, an obsolete, 3 year old OS. With the decision planned to go global, this means that any program written in ASM or C will not run on any CE operating on the newest TI OS 5.5.1 or higher!
#Ti 84 programs plus
Just a few days ago, TI Education announced that the most recent OS for theTI-84 Plus CE (-T) and TI-83 Premium CE removes the ability for the calculator to run any Assembly (ASM) code. If you want to get up to speed quickly, I made a video that summarizes the vast majority of all the information I've gathered across dozens of sources! There's a lot of information that wasn't covered in this thread so check it out if you want to know everything!
