  1. I'd like to say thank you the writers of TechLinked! The news got featured in today's episode! If you missed it here's the link:
  2. Exactly! (I should have added this in my post above) Games should in no way void the warranty. Even ASM games cannot damage the calculator and can be easily removed without anyone knowing they were ever there. As one user puts it, it's like putting a "WARRANTY VOID IF PUSHED" label over your car's gas pedal!
  3. Today, Critor (the founder of TI-Planet and a math professor) receive an email from TI-Cares displaying yet another action of TI pulling the rug from under our feet. Apparently running any game will now void your warranty! Note: This has been translated from French Source: TI-Planet This email just raises more questions. Does this just mean ASM games? Does it cover BASIC or Python games? Why don't utilities void the warranty? If I learn the answer to any of these questions I'll be sure to keep you guys updated. This is quite a confusing an infuriating time. Now for some replies: @Geek95 I hope it gets on the show today, thanks for letting me know about the site, I'm glad it's catching on more! Yup, the community will find ways around the restrictions.
  4. Haha, that's literally the whole point of Exam Mode, to disable programming and other features schools may not want. Unrelated: do people use 0x5 at all around here?
  5. That's the biggest concern I had too, why bother having two calculators when you could have a smartphone that's better at doing both tasks? As far as my knowledge goes, it's not possible to completely recreate exam mode due to the color palette not being editable or something like that. Therefore, you can only change the status bar color to the Exam Mode blue/orange until the screen updates again. Having a rpi inside a calculator emulating it would be a fun project to try sometime! That's interesting, is there any reason to them being banned besides you being expected to do everything manually? Must be a pain needing to graph everything by hand. @commandblockguy I'm not a fan of needing to go this route either. In an ideal world TI would just admit their mistake and roll back their decision. Obviously TI's not going to do that but it'd be nice if we could come to some terms of agreement before exploit war becomes a thing.
  6. I expect TI's decision to ban ASM to end up performing just as poorly as Sony's decision to add restrictions to the PS3. The community has been brainstorming some ways TI could keep their restricted OS but also let the community have something to focus our efforts on rather than finding exploits. Here's a few ideas (from most feasible to most difficult), which ones do you guys like best or is there other options you'd like to add? TI could create a 'developer' OS which removes virtually all restrictions in the normal TI-OS. However, this OS would not include an Exam Mode and therefor could not be used in testing centers. Although TI-OS would come pre-installed, the developer OS would be an option for those who don't need Exam Mode. A different OS color scheme could differentiate it from regular TI-OS (i.e. a red status bar). A calculator with the same internals, but with the developer OS pre-installed. This 'TI 84 Plus CE Developer Edition' would differentiate itself from normal calculators with a colored shell that specifically states it cannot be used for testing (I've embedded a rough concept to the right). Similar to how TI already has an ez-spot color scheme to identify classroom sets of calculators. A completely new calculator with different internals. This 'TI-84 Plus CE Developer Edition' would have the developer OS and the same colored shell as I mentioned above. However, it would include a modern ARM CPU (rather than the 20 year old eZ-80) and much more RAM and ROM. This would make it more similar to the HP Prime G2, but with the familiarity of TI-OS. That's the main ideas, if you guys have any options you'd like to add feel free!
  7. The Washington Post made a great article back in 2014 that covers why TI is so popular and expensive. It's still relevant today: The unstoppable TI-84 Plus: How an outdated calculator still holds a monopoly on classrooms (Internet Archive version for those with adblock) If you never knew about any exploits, then it's not wrong at all. In fact I'd suggest not upgrading past OS 5.3.0 because TI started introducing restrictions in OS 5.3.1. OS 5.3.0 gives you the best features and fewest restrictions. You can find the OS on TI-Planet's site. Even Ndless (the Nspire jailbreak that allows ASM) is in danger of being squashed out for good. The new Nspire CX II calculators are quite different from the previous generation and can't use any language but Lua. Python is coming sometime in the future but if it's anything as poor as the TI-83 Premium CE's implementation, it wont be a proper substitute for ASM/C either.
  8. Kelvinhall05: Programming these calculators is very important. For example, the community is a stop gap that prevents bugs TI missed from effecting you negatively. You may not expect us to be doing much but we're doing all we can to improve TI's calculators. Also, what jagdtigger said ^ GDRRiley, that'd be correct, unless someone on an older OS upgrades, only newly manufactured calculators will have the restrictions. Unfortunately, these new calculators will eventually outnumber the unrestricted ones.
  9. That's one of my points in my post above, hardly anyone updates their calculator which means the bug will always be around on older calculators as long as testing centers don't force students to upgrade. TI removed the native ability to downgrade in 2016 or 2017. Like Zodiark said, some people just find it fun to bring retro games to a portable device most students have. We love expanding the calculator's capabilities while dealing with the challenge of intense hardware limitations. It's what got me and hundreds of other interested in choosing computer science as a field of study.
  10. I know I'm new to this forum, but I have been an active member of the calculator community for over 4 years. I'm trying to spread the word about this as much as I can, hopefully achieving a segment on TechLinked, and to give TI enough negative backlash to consider negotiating better terms with the community. I'll keep this article as an overview, but I'll link my in-depth sources at the end. What exactly happened? Just a few days ago, TI Education announced that the most recent OS for the TI-83 Premium CE removes the ability for the calculator to run any Assembly (ASM) code. 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! Click for animated PNG (Source: TI-Planet: Français | English) Why did this happen? 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. 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. Why is this so frustrating? 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. This build given to TI-Planet had all the benifits of the new Python abilities, however ASM was not banned on this build. 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. 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 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. 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'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 does offer alternative programming options like TI-BASIC and Python, but as TI Planet user jean-baptiste boric points out on Cemetech: Source: Cemetech: English 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. I think forum Planet Casio explains it better than I can: Note: I have paraphrased the French to English translation in order to make it sound as coherent as possible. (Source: Planète Casio: Français | English) Now that ASM is banned and this situation can't get much worse, the community is already finding exploits that allows not only the ability to run ASM code anyways, but ways to bypass TI's insecure Exam Mode (which was only ever 'secure' because the community was careful not to release the exploits to the public). The community is already brainstorming alternatives that will both satisfy TI and the dedicated programming community. We're doing our best to come to terms with TI and avoid creating another cat-and-mouse game of finding and patching exploits (which happened on the Nspire). Conclusion: Like I said at the beginning, my goal is to spread the word about this as much as I can. Although this is only effecting the CE line up of calculators right now, TI has not ruled out releasing updates to older models that also bans ASM. (Source: An e-mail from TI-Cares posted on TI-Planet: Français | English) Sources: These go more in-depth than I did in this article. TI-Planet's 20 year history of ASM on calculators is a particularly great read.
