We're not expecting more than a few lines, just making the program coherent with itself.

, but I can still try. 
 | 1st crystal ball question: Copy exactly in a text file the 1st Basic code portion visible between 0min11s and 0min20s in the above video. |
 | 2nd crystal ball question: This 1st Basic code segment is actually taken from a much larger project. What could it be? (multiple answers possible) |
 | 3rd crystal ball question: This 1st code segment is actually incomplete and the end is missing. Without changing the already copied lines, develop and add a coherent end for the code and add it to your text file. (multiple answers possible) |
 | 4th crystal ball question: Copy exactly the 2nd Basic code segment visible between 0min32s and 0min39s in the above video. |
 | 5th crystal ball question: Many families of Basic languages have existed, and the 2nd code segment actually uses a very specific dialect of Basic.
|
 | 6th crystal ball question: This 2nd code segment is actually incomplete and the start is missing. Without changing the already copied lines, develop and add a coherent start for the code and add it to your text file. (multiple answers possible) |
 | 7th crystal ball question: Copy or adapt the 2nd code segment on the hardware, emulator or software of your choice. (the choice of monochrome or low definition screens is not penalized - only correct/complete adaptation of the code within the chosen constraints is taken into accound) Ignoring the part you had to complete, what does this 2nd code segment perform? You'll send:

Extracts from the rules:
- If we receive several entries from you, only the latest will be valid
- we will grade you answers once the contest is finished, and we will establish a ranking
- if several people end up with the same grade, the sending date/hour will be used to choose
- each winner will be contacted in the ranking order, and will be able to choose among the prizes left in

News / TI-Planet arithmetic contest: the results
« on: May 18, 2013, 05:47:43 pm »
Crossposting the results from http://tiplanet.org/forum/viewtopic.php?t=11914
You probably know it, TI-Planet recently organised a calculator programming contest. The aim was to find the n-th prime palindrome as fast as possible.
By the way, you can find informations about it in the annoucement topic.
The deadline of the contest was a few days ago, and we have now completed our tests. It's now... results time!
TI-Nspire (BASIC) category
We received 14 entries, but we retained only 13. Indeed, one of the entries, PP08, outside competition and which dwarfed all others, will be presented in a separate news post.
Let's reveal the names hidden behind a few letters and numbers that were insuring impartiality during the grading
Bisam (PP01), Luc H. (PP02), Loulou54 (PP03), Benjamin K. (PP04), Michel B. (PP05), sammyMaX (PP06), Lepzulnag (PP07), Excale (PP08), Louis A. (PP09), Compu (PP10), Tangrs (PP11), Jim Bauwens (PP12), Jean-Yves L. (PP13), Handers (PP14)
Bisam (pp01) wins, with the faster program in average, even if his results are a bit "by steps" : indeed he uses a sieve that he fills up little by little, and the "jumps" are due to some big range without palindromic primes.
Then :
We received 5 entries.
Let’s reveal the (nick)names:
Nikitouzz (PZ01), Xeda (PZ02), Weregoose (PZ03), Linkakro (PZ04), Samer A. J. (PZ05)
Xeda [PZ02] wins, with the fastest program (which is also the smallest one!), using a palindromic number generator and primality testing (trial factoring).
Xeda earns a TI-84 Pocket.fr + 4 TI-Planet stickers! :bj:
The runner-ups are Weregoose [PZ03], with another very small program (props for size optimization), and Linkakro [PZ04], who earn respectively 1 TI calculator poster (model can be chosen as long as supplies permit it) + 3 TI-Planet stickers and 2 TI-Planet stickers! (Sorry for Nikitouzz who gets the 4th place because there weren't any explanations
)
TI-z80 Native Code category
We have received 3 entries : a single one in pure z80 ASM, the two others in Axe
Let's reveal the (nick)names:
Jacobly (PA01), Steven W. (PA02), Félix G. (PA03)
There hasn't been much of a competition, the two Axe programs being very limited: no handling of integers > 16 bit.. If Axe is still very good at what's it's been made for, the algorithm contest purpose here is clearly not its stronghold.
The winner is therefor unquestionably Jacobly [PA1], who earns a TI-84 Pocket.fr + 4 TI-Planet stickers ! :bj:
Notice that Jacobly's TI-z80 ASM program is actually faster than Bisam's TI-Nspire BASIC program, while the processor is almost 9x slower ! This can only make us regret once more that TI does not open to ASM its TI-Nspire platform...

- sammyMaX [PP06], a bit slower than Bisam's in general, but whose execution time increases with the input value in a moderated and regular way. (probabilitic algorithm : Miller-Rabin)
- Louis A. [PP09] (who also uses Miller-Rabin, but in a less optimal way).

General Calculator Help / Re: Ti-nSpire CX upgraded to CAS but no mViewer/ndless - why?
« on: May 18, 2013, 03:09:53 am »Ok - this was my original thought too.. so as I said above - I attempted to install the 3.1.0.392 version... it got stuck on the loading screen after trying to install the os... basically I got through the steps to delete the OS then copy the new os over..
No.
Once you use nLaunch, installing an OS means sending its file to /nlaunch/phoenix.
Just follow the CAS instructions in my Ndless 3.2 switching pack:

News / First real HP-Prime prototype HD photo
« on: May 17, 2013, 08:32:33 am »
A fan who wishes to remain anonymous, took the initiative to send us a great gift for you tonight ... 
The first HD Photo ever of the new HP-Prime graphing calculator taken at the NCTM conference, a calculator scheduled for back to school 2013!
The photo is a little blurry unfortunately, but do not forget that HD picture for lovers of high resolutions:
We notice (thank you Adriweb) some important differences as the model name is different: instead of "HP-Prime Graphing Calculator", here we get a "HP Advanced Graphing Calculator " meaning it's probably a prototype.

News / Discover the Casio ClassPad Ⅱ (fx-CP400) software
« on: May 12, 2013, 11:00:01 am »
Casio has just released the emulator of its new touch-based, color calculator the ClassPad Ⅱ (fx-CP400)! 
Let's notice that unlike HP, this emulator is not be free and will stop working if you don't buy and activate a license within 90 days.
The home screen, is, like the TI-Nspire, made of a menu that lets you choose the application (which is highlithed by a color)
No less than 13 applications are available : calculations, eActivity, Statistics, Spreadsheet, graph&Table, Geometry, Conics, DiffEq-Graph, NumSolve, Sequence, Financial, Program, COmmunication, System and even a solution to acquire data from sensors like on the Nspire !
The "main" (calculations) app is worthy of its name and responds to what's expected in 2013 from a calculator, allowing simulataneously :
Discover now the version 1.00 of the new ClassPad Ⅱ calc !

News / USB mouse & keyboard together on a TI-Nspire thanks to Ndless and a USB hub!
« on: April 21, 2013, 07:48:20 am »
In a previous news came out the new Ndless 3.1 r765 with USB support! 
For the moment, USB support is not available from Ndless programs, but it allows the use of USB devices that are not officially supported in the Nspire OS.
Currently, only USB keyboards and mice are supported through Ndless.
The first problem you'll have is the connection of these devices. Because in order to work properly here, they will have to be connected to the TI-Nspire via a mini-USB A (male) plug you'll have a lot of trouble finding because it has been abandoned by the USB standard.
However, several solutions do exist.
Firstly the barbaric method: just take the mini-USB A (male) <-> mini-USB B (male) cable coming with any TI USB graphic calculator and sacrifice it in order to replace the mini-USB B (male) plug by a USB B (female) plug in order to be able to connect USB devices equipped with an USB A (male) plug.
You can also directly buy this type of cable. But as they do not conform to the USB standard, they will be available exclusively online at a few shops and therefore expensive.
Or if you're a little smarter, just use a method of my invention which will have all the benefits! :bj:
Simply buy a USB hub that connects to the host via a removable cable and a mini-USB B (female) plug.
You can then connect directly to the TI-Nspire with the mini-USB cable A (male) <-> mini-USB B (male) provided with the calculator!
No need to sacrifice your cable anymore!
And as a bonus you can connect USB keyboard and mouse simultaneously!
Let's test:
USB mouse and keyboard work very well together!
For the mice, it is sometimes difficult to activate the pointer when it is hidden - but if you think about it, this is the TI-Nspire OS fault - it is not uncommon to have to polish the TouchPad for long seconds touch before the pointer shows up. So in short nothing wrong, it just works as weel as the TouchPad.
For the keyboard, too little keys are supported in order to get rid of the TI-Nspire keyboard.
We've got:

But very soon, you'll be able to use your TI-Nspire handheld with the same comfort as the TI-Nspire computer software! ;D
See you soon! :D

Thank you for your pics.
I've just newsed on this mistery:
http://tiplanet.org/forum/viewtopic.php?t=11628
I've proposed an explanation after analysing TI-Nspire CX PCBs from HW-A to HW-F.
I might be wrong and without further information, my guess is as good as yours.
