Retour des applications TI-Nspire iPad sur l'App Store !

New postby Adriweb » 19 Feb 2013, 12:23

Salut à tous,

Il y a quelques jours, TI publiait sur l'App Store (iOS) ses applications TI-Nspire et TI-Nspire CAS pour iPad, et nous avions bien couvert cet événement.

Mais très rapidement (quelques heures après la sortie), celles-ci se virent retirées pour problème de "sécurité" / paramétrage App Store.

Et bien, les voici de nouveau disponibles aujourd'hui 19 Février, et on peut même noter des améliorations :
Nouveautés de la version 3.4.1
- Nouveauté : iOS 6.1
- Nouveauté : compatible avec l’iPad écran Retina
- Améliorations : Correction de bugs et optimisations


Mieux que prévu, donc :)
Hi,

A few days ago, TI released on the iOS App Store its iPad TI-Nspire Apps (CAS and non-CAS), and TI-Planet covered this event live.

However, the app got pulled out of the App Store quickly, by TI, for "security" / app store issues.

Well, they are now back on the App Store, with a changelog noting things we weren't even expecting then :)
Version 3.4.1 :
- Added: iOS 6.1 support
- Added: iPad with Retina support
- Improved: Bug fixes and optimizations


So, better than expected :)

Press Release :
Show/Hide spoilerAfficher/Masquer le spoiler
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 .

De nouveaux prototypes transformables en véritables Nspire!

New postby critor » 21 Feb 2013, 10:29

Sur les sites de revente en ligne, on trouve régulièrement par vagues des prototypes TI-Nspire.

Ces derniers ressemblent souvent comme deux gouttes d'eau aux modèles de production, mais n'accepteront que des OS signés avec les clefs RSA de développement.
579 1581


Il est donc impossible de les mettre à jour avec les OS publiés par le site de TI qui sont signés avec les clefs RSA de production. Et comme les OS de développement ne sont bien évidemment pas diffusés, il est impossible de les mettre à jour avec un OS récent.

Nombre d'entre vous ont été victimes de ces escroqueries, se retrouvant avec une machine équipée d'un très vieil OS que l'on ne peut pas mettre à jour.



La vague de 2009-2010 incluait principalement des prototypes TI-Nspire ClickPad équipés d'OS de développement 1.1 à 1.2.

Heureusement, en mars 2012 TI-Planet te sortait enfin un tutoriel afin de transformer les prototypes TI-Nspire ClickPad en modèles commerciaux acceptant les derniers OS publiés! :o

Il s'agissait en fait de reprogrammer les Boot1 et Boot2, et la manipulaton était des plus aisées car entièrement logicielle! :bj:

En effet, sur les prototypes le brochage de la puce NOR du Boot1 est différent et cette dernière est donc réinscriptible sans besoin d'aucune manipulation matérielle:
596


Pour cela, il suffisait simplement d'installer les OS de développement 1.1 ou 1.2 pour lesquels Ndless avait été porté.



Mais... Récemment, une nouvelle vague de revente massive de prototypes TI-Nspire s'est déclenchée en Chine, et a déjà touché plusieurs d'entre vous.

Cette fois-ci, on trouve des prototypes TI-Nspire ClickPad plus récents, parfois équipés d'OS 1.4.

Or, ceux-ci ne pouvaient pas être transformés car ils disposaient d'une protection antidowngrade: on ne pouvait pas y réinstaller les OS de développement 1.1 ou 1.2 :(

Heureusement, un point commun entre tous ces prototypes plus récents est qu'ils viennent tous équipés avec la version 1.1.8981 de développement du Boot2.

Voici donc aujoud'hui une nouvelle version de downgradeFix, "downgradeFix prototype" qui permet de faire sauter la protection antidowngrade si présente sur les TI-Nspire équipées du Boot2 1.1.8981 de développement! :bj:

Une fois cette protection retiré, il ne reste plus qu'à appliquer le tutoriel habituel pour disposer d'une nouvelle TI-Nspire! :D

Méthode testée avec succès du 1er coup par notre membre fortytwo, sur son prototype TI-Nspire ClickPad qui venait en OS 1.4, qui est désormais devenu une véritable TI-Nspire! :bj:
Merci fortytwo! :bj:!

Debian Linux sur Nspire

New postby Lionel Debroux » 24 Feb 2013, 09:11

Fortytwo nous démontre aujourd'hui une distribution Debian standard tournant sur Nspire :)

2131

Ca ne présente pas de difficulté technique particulière, mais c'est quand même bien que quelqu'un ait pris le temps de le faire :)
* debootstrap / multistrap pour la création du rootfs;
* utilisation d'une board ARM physique pour finir le travail, ou bien de qemu-arm-static contenu dans le package Debian qemu-user-static:
Code: Select all
# Make sure we have the appropriate packages.
apt-get install debootstrap multistrap binfmt-support
# This package ought to register the appropriate definitions for binfmt-support
apt-get install qemu-user-static
# Load binfmt support
modprobe binfmt_misc
# Start a debootstrap that will fail when trying to install the packages
mkdir $DEST_DIR
cd $DEST_DIR
debootstrap --verbose --arch=armel sid . http://ftp.fr.debian.org/debian/
# Fix it. ln assumes the programs are on the same partition, use cp instead if they aren't.
ln /usr/bin/qemu-arm-static ./usr/bin/qemu-arm-static
# Start debootstrap again, and while at it, we can add some packages into the mix :)
debootstrap --verbose --arch=armel --include=locales,build-essential sid . http://ftp.fr.debian.org/debian/

(j'ai fait ce script il y a quelques mois au boulot, mais je n'ai pas essayé de l'appliquer à la Nspire)

Mise à jour Ndless+

New postby critor » 25 Feb 2013, 15:29

Ndless+ est un kernel basé sur Ndless 1.1, qui permet l'exécution de programmes assembleur sur les prototypes TI-Nspire CAS+ testés dans des classes pilotes en 2006-2007 avant le lancement des TI-Nspire.
Image


Aujourd'hui, Ndless+ passe en version 0.3 avec:
  • un script permettant de l'installer sous l'émulateur Nspire communautaire de Goplat, et donc de tester rapidement ses programmes sans besoin de connecter une vraie CAS+ :bj:
  • plein de nouveaux syscalls pour les développeurs! :bj:

Amusez-vous bien! ;)
