News / HP Prime: the official video!
« on: April 19, 2013, 03:46:15 am »
On the official "hpcomputers" Youtube account, there's now a marketing clip of the HP Prime calculator :)




The 3.5" multi-touch color screen is mentioned, and we can also see the alpha keys superposed to other keys (like on the TI-Z80, TI-68k and many other models from other manufacturers), as well as a battery :D
However, no information about the CPU, RAM and storage room - which are the pieces of information of highest interest to me, as they truly are what defines a platform :(

Through functionalities such as dynamic geometry, and specific students mention, we can see that the calculator is much more students-oriented than many other HP calculator models.

Speaking on my own, I think that the alpha keys superposed with other keys are much more convenient than the Nspire keyboards' two sets of keys and their tiny keys - even with long, thin fingers.

Looks like, from the clip and image, that those who indicated that its screen resolution and CPU / memory characteristics were the same as the 50g's, didn't have access to the correct pieces of information.

Anyway, this calculator technically makes HP calculators much closer to the state of the art in the matter of calculators, or even define said state of the art :)
Of course, this calculator is unlikely to be cheap, but all calculators are too expensive for the limited functionality they provide. Earlier today, I read once again about a platform much closer to its real price: a $12 phone: http://www.bunniestudios.com/blog/?p=3040 ...

We'll see what TI does with the CX Premium :)

Thanks.
And sorry, I didn't know the entire ticalc.org archive could fit on only one CD at that time.

363
Darn that is cool. I remember that ticalc.org used to be affiliated with TI, but sadly were taken off their website because their archives contained innapropriate material (the Drug Wars game and ASCII porn)

Not exactly - let's be a little more accurate.

Because TI calculators were sold with a ticalc.org CD.
That CD was containing a part of the ticalc.org archive, and there was such stuff in that part.

I followed the tutorial, however, when I reached the part where it says to press 2 and 2 again in nsNandMgr, I receive an error saying
"I/0 error on file /documents/ndless/boot2.img.tns"
Help?

I'm checking - but for now and until TI releases a new Boot2, you should not need to reflash your Boot2.
Didn't your calculator already come with Boot2 3.1.0.16 ?

Would it be possible to have a port of this for the TI-84 Plus C Silver Edition ? ;)

A SmartPad App for this calculator doesn't seem to be planned by TI.

Some months ago we got nLaunch, a permanent OS loader for TI-Nspire ClickPad/TouchPad.
It was using a flaw in Boot2 1.4, and let you run any hardware-compatible OS by skipping all checks (RSA signature, minimal installable OS version, model ID, model type...).

I then released a pack based on a fork of nLaunch, enabling you to have both 3.1 and 3.2 OSes on your calculator and to switch between them - making you able to run both Ndless and Lua 3.2 programs!  :thumbsup:



It didn't hit the news here maybe because it was released on the 1st of april, but nLaunch has now been updated with CX support.

And tonight, I'm releasing you a new pack which will let you enjoy the best of both Ndless and Lua worlds on your TI-Nspire CX too! :thumbsup:

News / Re: TI-Connect 4.0 and 84C OS 4.0 released !
« on: April 11, 2013, 10:45:37 am »
Since 2007, TI adopted a strategy that involves releasing calcs before everything is even ready at all.

So it's up to us - let's resume TI's work and release patches/fixes for the current TI-84+C OS bugs like we allready did for the TI-83+/84! ;)

I guess I have one or two more questions for now... Sorry for the slew of questions but hopefully they'll help clear things up for people besides myself as well.

  • I'm assuming that we are allowed to pre-calculate and store the values of the first few prime palindromes, like the ones with 2 or fewer digits (2, 3, 5, 7, 11), correct? Some algorithms can't really find some of these on their own and instead depend upon them being given. Storing these special cases should take less space and running time than modifying the algorithm to find them itself, and in some ways modifying the algorithm to find specific values is more or less the same thing, right?
  • Related to the question above, should we agree upon some hard rule about what values can be pre-calculated and stored? I assume this rule would either have to allow a precise set of values or an maximum amount of values.


There is no hard-rule, but we perfectly understand that you have to start the algorithm by intialising some variables to the 1st prime numbers.

If you find out how to interface Ndless with the calculator app, you can.
Indeed, you have to program a 'function', which will return a usable result.

News / TI-Planet arithmetic contest !
« on: April 04, 2013, 12:49:20 pm »
Hello everyone,

It has been time TI-Planet have not organized a contest, and here is the lack filled ;)
So we organize an international contest, about 5 weeks, mixing arithmetic and algorithmics.


Make a program, as fast as possible, to find the n-th prime palindromic number.


We'll gladly accept programs for the:
  • TI-Nspire
  • TI-82Stats/83/76
  • TI-83+/84


Prizes include:
  • a TI-Nspire CX for the fastest TI-Nspire program
  • a TI-84 Pocket.fr for the fastest TI-z80 program
  • TI posters
  • TI-Planet stickers








Have fun, trying to be the fastest! :thumbsup:

We'd still like to have shome photos of the 4-layer PCB ;)

It has 2.55MP.

Asm programs just work as good (or as bad) as on TI-84+ with 2.55MP.

It's just a sticker I use to identify my own CX calculators when I use them in class, as they aren't labeled "school property".
The TI-Nspire CX Premium doesn't look like that at all.

By the way, here is a CX running a CM OS:

The Navigator module in unrelated.
It's just that I usually keep it plugged.

If I do this, will I have to delete everything off my calculator?

No - just the OS.

Some photos if you still don't believe me:

it is not easy to believe this kind of things today...  :P


Just try it? ;)
