News / Re: New TI-Nspire CX hardware revision K
« on: September 04, 2013, 08:47:37 am »
Well apparently it's the common thing now that we can only be sad about : none of the recent new big calcs (HP Prime, Casio fx-CP400) offer native coding capabilities. The Nspires were just a bit ahead of their time, I guess ; maybe since TI is the major seller in the US.
It's mainly because the exam institutions require them to lock down the device (or at least make it very safe), and well, TI/HP/Casio just go the hard way by not providing native access on top of PTT.
Especially when we're talking about their flagship product : they certainly don't want troubles with the exam institutions arguing wethere the platform is very secure or not... (and not only that, but they want to keep their main customers (teachers/schools) in trust, saying that protections are effective etc.

We can see the "quick" reaction after nlaunch, and we continue to witness its extent even these days (OS 3.2.4 with now boot2, new HW revisions blocking exploits upstream (since boot2 etc. can't be downgraded) )


And also, I wouldn't think of native programming capability as an sole argument of selling (like "I want to program in ASM so I'll buy a 84+"), but more of a bonus to a choice when buying (like "I'd prefer buying this calc over this one because there is also native coding capabilities"). And since TI customers (more than 99.99%) are not native coders, they (TI) strictly don't care about it.



Edit : by "exam institutions" I mean "standardized testing regulation authorities", thanks Lionel :D

TI-BASIC / Re: Weregoose's Binary Conversion
« on: September 04, 2013, 06:35:38 am »
Well, I was stunned by how incredible Weregoose's routines were when I discovered them some years ago that I made a copy at some point (might not contain all, though...) and here it is uploaded :

TI-Nspire / Re: nSpiKx - TI-Nspire emulator for Mac OS X (Cocoa)

How is that different from the normal, expected behaviour ? :P

Happy birthday Omni.. and TI-Planet, same time :P

TI missed the boat as well in France with the color 84+ (online exclusive for now)
They never intended to sell it in stores ;)

Lua / Re: How to distinguish TI Nspires?
« on: August 31, 2013, 04:17:39 pm »
Ok, when re-reading it seems my reply isn't totally what he wants neither :P

And well, nope in Lua (let alone Basic), you can't, sorry.

Using ndless (or well, in Lua with native extensions), you probably can.

Lua / Re: How to distinguish TI Nspires?
« on: August 31, 2013, 02:14:45 pm »
ElementCoder : I believe he meant programmatically, from a Lua script ;)

So, yes (but not exactly what you would like, after re-reading your question), especially if the script is going to run on OS 3.2 or later :
See here : http://wiki.inspired-lua.org/platform

Quickly :
[lua]platform.isColorDisplay[/lua]() : Returns true if the display of the host platform is color-capable (Nspire CX and emulator). Returns false if the display is grayscale (Nspire non-CX).
[lua]platform.isDeviceModeRendering[/lua]() : Returns true if the script is running on the hand-held device or in the emulator (with the calculator view), and false if the script is running in the normal view of the emulator.
[lua]platform.isTabletModeRendering[/lua]() : Returns true if the script is running on a tablet device (iPad app) and false otherwise.
[lua]platform.hw[/lua]() : returns a number corresponding to the type of device the script is running on.


No further ways to identify a specific device, though.

Good job you two :)

Also, Extended, why not both ?
(well, eventually).

And this made me think that some files (and not just a few) are not .tns directly, but are zipped (or rar[er] - pun intended, whoooo - anyway, rar would be a pain on-calc, zip, probably less.)
So, should I add another "type" field to the api response, or will that just be left to the client to parse from the file url ? (it would be just one line in php, probably same or a bit more in C...)


Edit : Levak / ExtendeD : I reordered the doc (see Levak's post ^ )

Other / Re: Cheap Software Defined Radio
« on: August 30, 2013, 04:15:19 pm »
Ah !
I do also have a DVB-T stick, although a cheap model I found, not a Terratec one.

I'll try that (if my dongle is compatible...) , it seems very cool :D

370
Ah, that's indeeed pretty cool :)

Ok, I'm back to France, here are some changes :

- Removed the limit in number of results (it was 500 before)
- You can now list all files for a given platform, as requested :   ...&req=search&platform=68k   for example.
- Changed all occurences of "title" by "name" which makes more sense, I believe.
- Rewrote the wtf-esque multiple-fields-to-array things, which simplified other things.
- "Author", "Category", and "Platform" fields are now always arrays of string(s)

HTTP Auth is still in the todo list but it quite heavily depends on getting apache to run correctly, which is not a quickfix... For now, no changes to the the method of getting results : http get/post with the api key parameter.

well, for them, the least native developers/hackers, the better, so indeed, as stated multiple times, it's just the lack of motivation / amount of people that makes TI "win" the native fight for a given OS version.
If somebody skilled is motivated enough to find exploits, I'm sure he'll find it.
That's what  Extended and the other ndless contributors have done over time ! But the lack of time was/is more the reason for not having an ndless 3.2 yet I guess

373
well, definitely :D

Has any boot1 flaw/exploit ever been found on any version, actually ?

General Calculator Help / Re: New to calculators
« on: August 27, 2013, 11:41:10 am »
Oh, I know phones are mostly not allowed, but that has never prevented any students from doing so, at least that's what I see everyday.
But in theory, playing on your calculator on or your phone is "the same", as in you're not listening...

And yes, me too I also was making programs related to the current lesson, although (in France at least), in my HS years, there wasn't much that could be related to programming or could be done through programs, sadly.

And anyway, to continue my point : if I had an Nspire at that time, programming math related things would have been 9001x easier than on the 84+ ^^

General Calculator Help / Re: Installing 3.1 on Ti - nspire cx CAS
« on: August 26, 2013, 10:55:05 pm »
For now, to get an OS on it, you can download the correct one from http://education.ti.com/nspire/os324. There may be an exploit found which takes care of this downgrading issue, but for now, a calculator with an OS is better than one without.
So far, no exploit AFAIK, though...

Getting our hands on such a machine would be helpful for anyone if we (well, the people who do know how, at least :P) end up finding what's changed and especially how to reverse/counter that.

I wonder if trading (exchanging) a machine with someone who has it, for a non-J one would be OK ?
The less distance between people, the better, though, since international costs are not so negligible
