However, if it's not a memory issue, it's not an OS bug, but actually a bug in the script itself. Contrary to TINCS where the bug can be displayed in the SDK, on the handheld nothing happens, and a blank page takes the place of the script.

(which is why deleting the widget and Ctrl+Z-ing it restores it.)

What I do when Lua script crashes on the handhelds, when possible (it's not when they are storing external data...), it's that when it gets all blank, I just delete the tab when in thumbnail mode, and Ctrl-Z that. It reloads the original lua script, then.

Texas Instruments unveils breakthrough TI-Nspire Apps for iPad®
TI extends its most powerful graphing technology into apps
that will change the way students visualize, engage and interact with math

Now available on the App Store

DALLAS (February 20, 2013) – Texas Instruments (TI), the most trusted brand in graphing calculator technology, “took a major step forward in our mission to improve student understanding and achievement in mathematics” with the release today of two new innovative apps:  TI-Nspire™ App for iPad and TI-Nspire™ CAS App for iPad, said Melendy Lovett, president of Texas Instruments Education Technology. 
 “The apps fill a critical need for an all-in-one math teaching and learning tool designed specifically for the iPad,” said Lovett.  “TI is extending the proven benefits of TI-Nspire technology to the tablet platform.  TI’s goals are to provide educators with the most powerful math apps for the iPad and to engage students while helping them reach a deeper conceptual understanding of math. Beyond the new Apps for iPad, TI continues to support teachers by providing world-class professional development, and access to free classroom-ready activities for use with the TI-Nspire Apps for iPad; activities can be integrated seamlessly into curriculum and are available at TI’s Math Nspired website.”
The TI-Nspire Apps for iPad were designed and refined in collaboration with researchers and classroom teachers, including Stephanie Ogden, Dean of Research and Development at L&N STEM Academy in Knoxville, TN, who also teaches Pre-Calculus, AP* Calculus, AP* Statistics and STEM.
 “The TI-Nspire Apps for iPad are truly transparent technology, allowing students to touch and interact with math with little awareness of the tool in their hands.  Students experience mathematics more directly and they are beyond engaged—they are excited about learning,” Ogden said.
Unique features of the apps, which meet critical curriculum needs from 7th grade through college, include:
  • All-in-one functionality for performing calculations in proper math notation; graphing and exploring functions, equations and inequalities; constructing and exploring geometric figures; creating, plotting and analyzing data in lists and spreadsheets.
  • Interactive keyboard that toggles between math notation and QWERTY configurations for placing notes and instructions alongside problems.
  • Dynamically linked multiple representations of problems that encourage students to make crucial connections by observing how equations change as they touch and interact with shapes, graphs and objects on the screen.
  • Familiar operations for creating and saving documents and sharing them using email, iTunes®, and other file sharing options.
  • Interaction with the built-in iPad camera interface that enables students to take photos, import them into the app and overlay graphs and equations on them to illustrate abstract math principles in the physical world.
In addition, the TI-Nspire CAS App for iPad has a powerful built-in Computer Algebra System (CAS) which enables students to symbolically solve equations, factor and expand variable expressions, complete the square, find derivatives, compute limits, find exact solutions in irrational form and much more.

TI-Nspire Apps for iPad will be featured in two full days of workshops and break-out sessions at the 2013 T3 International Conference held March 8-10 in Philadelphia, Pennsylvania. 

The TI-Nspire App for iPad and TI-Nspire CAS App for iPad are available for $29.99 each from the App Store on iPad or at http://www.AppStore.com.  Teachers are eligible to receive a free, one-year license of the TI-Nspire and TI-Nspire CAS Teacher Software with purchase of one of the TI-Nspire Apps for iPad.  Detailed information about the TI-Nspire Apps for iPad, including a brief video overview, is available at http://education.ti.com/ipad .

So it wasn't the fact that it featured user programmable stuff?(which everybody's nagging about  for some reason)
Nah :P

Yeah I am curious about what was the security issue, although it could just have been a typical security exploit like some stuff Internet Explorer had on Windows, letting people access your iPad or something.
Nothing important. More of a user-annoying bug AFAIK.

Update :

The Apps are back on the App Store :)

- TI-Nspire non-CAS iPad application
- TI-Nspire CAS iPad application

Also, TI actually took some time to improve the app (which is why it took more time than it would have taken just to fix the "issue") :

Lua / Re: Updating WZGUILib
« on: February 19, 2013, 05:41:02 am »
This is part of the trick(s) from Jim Bauwens, in order to have simple sound output on Nspire 3.0.x (later OSes had print() removed....), with the RS232 port.
See here :


On Nyan Cat, Levak reused (& improved ?) Jim's code to have some background music (the Nyan Cat music :P)

Lua / Re: Updating WZGUILib
« on: February 18, 2013, 11:26:18 am »
Take a look at FormulaPro's source here, line 1938 :

https://github.com/adriweb/EEPro-for-Nspire/blob/488309ce5788116eed23b7ab65ee7dbfb2920efe/EEPro.big.lua#L1938

The on.draw is called by on.paint here : https://github.com/adriweb/EEPro-for-Nspire/blob/488309ce5788116eed23b7ab65ee7dbfb2920efe/EEPro.big.lua#L2661

All that is working on 3.2, and some code is supposed to make  it work on earlier, but looking at the whole thing code makes me wonder if it actually does. Anyway, mess around with that, it should work on everything with the 2 methods.

An example of early Full-screen hack, from Levak's Nyan Cat game : http://levak.free.fr/ftp/nspire/NyanCat/NyanCat.lua  (look at gc:begin())

Sadly, it doesn't :(
Apparnetly it's still 0 or 1.

But that could be a feature request.

No no no, my edit apparently didn't get seen :

Quote
Officiel statement: "Immediately after the TI-Nspire Apps for iPad were posted on the App Store, we discovered an issue with App Store settings and have temporarily removed these apps from the store. We are working to update these settings and will repost the apps as soon as possible. "

I don't know why it was first said to be a "security" issue since the real thing behind all this, from the user point of view, really has nothing to do with a flaw/exploit or anything. It was just a bug, maybe with syncing (?) or something, since it's said to be related to the App Store settings. The bug was annoying, at first, but that the auto-saving feature made "acceptable" in certain conditions, since the launch time is quite fast. (but once it's fixed, it's definitely going to be better.)

Also, ikj, it's not an emulator, the whole thing has been rewritten and compiled for iOS.

General Calculator Help / Re: How to run programs on Ti-nspire?
« on: February 07, 2013, 10:35:37 am »
No, I also believe the issue here is that you have a non-cas device while the program requires the CAS engine.

To be a little more precise, the issue is, for the user, more of a bug, in its appearence. It's not something dangerous ;)
(Also, there is the auto-save, which I love.... :P)

Edit : Officiel statement: "Immediately after the TI-Nspire Apps for iPad were posted on the App Store, we discovered an issue with App Store settings and have temporarily removed these apps from the store. We are working to update these settings and will repost the apps as soon as possible. "

More discoveries :

Here are some changes in the Lua API (dump of _G, so, we don't know if there are any more events like on.xxxxx)

- a new platform.apiLevel : "2.2"
- a new table, touch :  touch = { enabled, xppi, ppi, isKeyboardVisible, isKeyboardAvailable, yppi, showKeyboard } --these are all functions to call
- a new function in the platform object : platform.isTabletModeRendering -- self explanatory.

EDIT :
Got this from TI : "The App has been temporarily pulled this morning due to a security issue in the final build. We are working to get it fixed, but we don’t have an ETA on when it will be back up for download – might be a few days. It was just pulled in the past 30 minutes."
