Title: Can you use Math Apps Without Ndless

I have exam coming and 3.9 has some sweet features like area of curves or whaterver its called. Anyway I'm pretty sure these apps work without ndless but I want to make sure that if I upgrade to 3.9 its still useable.

If anyone any insight it would be appreciated.

Thanks

Most of them are either TI-Basic or Lua. If you are not sure, whether it works, just download them and run them. If it doesn't work they might be for ndless. But most of them should work with OS 3.9. You could also check whether they can be run in the student software, which doesn't support ndless.

3.9 got features? I thought it was identical to 3.6, but with Ndless protection.

Nah, 3.9 is bloody fast compared to 3.6 and its got a few extra features its pretty enticing!

By the way thanks for the help I've decided to go to 3.9

It's even slower than 3.6 concerning booting, opening files, touchpad, text input... At least for me.

Except for the basic who got a bit slower for Disps (at least that's where I think the issue comes from) and the Lua that got faster on some graphical operations (cf the comparison video (https://www.youtube.com/watch?v=XXjmvBTcO84)), there isn't much ... (area between curves + grid selection on the graph app, margin fixed on the calculator (available on 3.6 with a program (https://tiplanet.org/forum/archives_voir.php?id=51218) from levak), and some visual changes on D&S).
Plus anti-downgrade, of course, yeah.

What have you found that is going faster now, btw ?
(Also, which calc do you have exactly, and with which hardware revision ? (last character of the serial number, on the back))

I dont understand why Nspire is so slow.

It has like 64 mb memory and 100mb space. YET it manages to be slower than other TI calculators <_<

Seriously TI if you want people to use AND enjoy the product, dont just focus on security. I have had one and now i use ti 84+ even though nspire is there for me. And i am actually thinking of getting a Prime and get rid of TI forever

I do. They have debugging enabled. Makes reverse engineering easier, but everything much slower.

It's just the OS, not the hardware. Win 98 would run fine if it would run at all :D

I think the same, especially because the "focus on security" doesn't seem to work out, does it?

Honestly the Nspire speed is not that bad. Even BASIC has some decent math speedm. Graphics are slow-ish in that language and in Lua, speed is somewhat questionable when it comes to complex programs, but compared to the Casio PRIZM and ClassPad models it's an huge improvement. It's just that it could be much better and less limited and the fact Ndless keeps getting blocked is irritating. Also the way Lua works makes it hard to make fast smooth scrolling games with sprites compared to the HP Prime.

But of course, TI focuses on making the languages good for educational programs, not for games. Kerm, on the other hand, has recently shown that native languages and faster stuff can be VERY handy for educational purposes, though. See the STEM Behind Hollywood activities, for example.

A real argument about speed isn't about memory/space. It would rather be that it has an ARM9 clocked at 133 MHz and still manages to have so much overhead in the end that a "Disp i" in a for loop from 0 to 100 takes a crapload of time (which keeps getting worse every OS, weirdly enough). Fortunately in general is "good enough" for math/science stuff, and well, there is Lua for other things.
Also yeah, lol, as Vogtinator said, for several releases now they have debugging enabled (just fire up nspire_emu, you'll see), which is ridiculous for production builds. (but makes rev-eng easier for those who work on that - I still don't understand how that's something they haven't caught. Or maybe devs just want to see third-party dev more easily done... :P)

Seriously TI if you want people to use AND enjoy the product, dont just focus on security.
That's the community/enthusiast's perspective.
But because the Nspire series has been much more designed for a use on classroom, the target is now more oriented on teachers and school [boards]. Guess what they want ? Security.
Which is just not compatible with freedom as long as it's not done smartly enough to make everyone happy.

HP is absolutely no threat to TI, they are way too "late" in the market share race, and I'm assuming their budget is also way lower (have you ever seen other events as TI's annual T3 international conference, from HP or Casio ?)

Lua speed 3.6 vs 3.9!!

No, but they had many staff layoffs over the last few years. An issue though is that HP calcs are not available in most brick and mortar stores and many parents are reluctant about buying stuff online due to security reasons.

If they keep laying off staff to reduce costs, then I doubt they have much extra money to spend in extra events. They do have the HHC events, though.
