Calculators in General
Texas Instruments have finally released the new TI-84 Plus CE and TI-83 Premium CE OS, version 5.2, on their website. This new OS brings several major improvements to those two color ez80 calculator models, including what might be one of the largest TI-BASIC enhancements ever since 2010:

-Sending strings to the TI-Innovator via the Send() and Get() commands
-Many more TI-Innovator-related commands
-expr(): You can now solve math calculations that are stored in a string.
-eval(): Converts a calculation result into a string. @grosged 's sprite v3.3 library users might find this very handy.
-toString(): Same as above, but also handles the format in which the result was returned
-Wait: Pauses program execution for a specific amount of time. No more need for For(Z,0,999:End
-Pause command now has Wait abilities if you use the command to display text and specify an amount of time at the end.

However, that's not all, because if you program TI-BASIC directly on the calculator, the on-calc editor now shows the program line number inside the status bar! Some commands previously available exclusively in the CATALOG are now available via the PRGM key as well.

There are many more improvements, such as the ALPHA shortcuts on the TI-84 Plus CE, bringing this calculator closer to its French counterpart, and the release of a new application called Hub, which adds extra menus to the PRGM key during editing. Remember that for all commands, pressing the + key next to the name will bring up help on how to use it, with the syntax and required arguments.

And finally, new versions of Vernier EasyData, SmartPad, TI-SmartView CE and TI-Connect CE were released.



-TI-Connect CE 5.2: Windows and Mac
-OS 5.2: TI-84 Plus CE and TI-83 Premium CE
-Flash APPS: Vernier EasyData, SmartPad CE and Hub

Hello, walrusses! :walrii:
This is my first news post, now being a news editor, so let's get rolling:

A while back this and last year, Cumred_Snektron and I were creating official real-time post notifiers.
Unfortunately many new users and even some of the die-hard walruses that have been with us since the beginning of CodeWalr.us are still not aware of them.
So I would like to present you the two post notifiers today:

CodeWalr.us Post Notifier (works on Windows, Linux and Mac)


The PC notifier works well on Windows, Linux and Mac.
On Windows, it requires .NET framework and GTK-Sharp.
Linux and Mac need a full installation of Mono and the respective GTK packages.

The notifier allows configuration of audio notifications, visual pop-ups, the design of the UI and allows ignoring posts based on parameters such as title and content.
Other useful features include a customizable update interval and gzip compression to save you bandwidth.
The Source code is available under the terms of the MIT License on GitHub.
A discussion topic can be found here.

You can download the ZIP archive with all the libraries from here: http://data.bmuessig.eu/Projects/CodeWalriiNotify/Builds/CodeWalriiNotify_1_5.zip

On Linux you can run the following command-line in your terminal to install the notifier:
Code: [Select]
wget http://data.bmuessig.eu/Projects/CodeWalriiNotify/install_on_linux.sh && chmod +x install_on_linux.sh && ./install_on_linux.sh && rm install_on_linux.sh

Walrifier (works on Android)


The Walrifier works on Android only (sorry iOS people! :P) and displays notifications through the Android UI.
Cumred_Snektron kindly released the source code on GitHub.
It's features include bandwidth saving and a configurable interval between checks.
The original topic can be found here.

Calculators in General
Despite the recent DMCA takedown notices that Nintendo of America sent about Pokémon Uranium and Another Metroid 2 Project (AM2R), the TI calculator community has been rather lucky about fan games and demakes. However, did you know that in the past, calculator developers were also hit by cease and desist letters, e-mails or DMCA takedown notices by big game companies for copyright infrigments? This retrospective article will look back in time at some games that ended up on the wrong end of a C&D:

-Monopoly (Kirk Meyer's version) http://www.ticalc.org/archives/news/articles/0/2/2322.html
In 1998, Kirk Meyer, a notable calculator programmer of that era, was working on a TI-z80 ASM version of Monopoly. However, Parker Brothers did not like this and he was ordered to stop all development due to copyright infrigments. However, for some reasons he still managed to release an unfinished copy a while later. It's possible that he had an agreement with them later on or was allowed to publish what he had, but nonetheless, this marked one of the earliest instances of a calculator fan game being hit by a cease and desist letter. You can download the game at http://www.ticalc.org/archives/files/fileinfo/69/6993.html .

-Golden Sun: The Chosen One (Omnimaga) https://www.omnimaga.org/other-calc-related-projects-and-ideas/the-chosen-one/msg4890/#msg4890
Some older TI community members who were active on Omnimaga back in 2005 might remember this. Back in the days, Tenniskid493, decided to work on a Golden Sun clone for the TI-83 Plus. The game was to be called Golden Sun: The Chosen One and featured some of the nicest xLIB BASIC graphics at the time. However, Camelot did not like that and sent a cease and desist e-mail to TK493 telling him that if he released the game, he would be on the wrong end of a lawsuit. He had to change the name to The Chosen One and remove all Golden Sun content from the game. Like many calculator RPGs, this one was never finished nor released, but this incident was the same year as MaxCoderz' April Fools joke about Metroid getting a C&D (remember that, @tr1p1ea ? For other people, see below.) and it was enough to give the chills to authors of other calculator fan games originally released by other big companies.

-Space Station Pheta http://maxcoderz.org/forum/viewtopic.php?p=24389#p24389
Threefingeredguy got lucky on that one, but it still gave all of us a good scare, plus it happened shortly before the Golden Sun incident and after April Fools 2005's MaxCoderz joke. The authors of the original Space Station Pheta discovered that 3fg was porting it to the TI-83 Plus and were happy that he loved the game enough to port it, but not the fact he didn't ask them first. They, however, were nice, and allowed him to continue on. But there was a catch: Development was restricted to the TI-83+/84+ per the original game maker's request. Unlike Golden Sun, this game came out and we were graced with a great calculator classic. Nonetheless, think twice before porting it to a color calculator!


Feel free to share more in the comments below this article if you remember similar fan game DMCA/C&D incidents in the TI community or if you saw any happen in the Casio or HP community. But before we stop writing, let's now look at other similar incidents that happened in the TI community, but instead of involving a calculator fan game and a big game company, involved the TI community vs Texas Instruments themselves:

-TI-News C&D from TI requesting site name change http://www.ticalc.org/archives/news/articles/4/40/40306.html
Although this also had something to do with a ROM sharing C&D, TI asked them to change their names too in the process. That part of the C&D was countered, though, so TI-News could keep their name. Can you imagine if TI started disallowing all sites to use TI in their names or domain name?

-TI-83+/84+ Private RSA key factoring
This is the most widely known episode of DMCA takedown notices in the TI community, as it made news on several sites outside the TI community. TI requested that people take down the private RSA keys from their website. With the help of the EFF, the initial DMCA takedown notices were countered, no reply was received then as a result people were able to host the keys again. However, over the years TI responded by locking their calculators even more against hacking (such as using 1024 and 2048 bits RSA keys instead of 512, which cannot be factored in a reasonable amount of time with today's technology)

-Ndless 1.1 and OS 1.1 hosting (this one is a bit of a grey area, but is included anyway due to the nature of it)
Hosting Nspire OS 1.7 and 2.0 without TI's permission? No problem. OS 1.1, on the other hand? Cease and desist letter! Back in 2010, TI-BANK hosted copies of all TI-Nspire OSes on their website for future posterity, as TI was taking down legacy files from their website one by one. Back then, Ndless 1.0 and 1.1 only ran on OS 1.1, so TI sent a lawyer letter to TI-BANK requesting the removal of the latter. It was seen as a direct attack towards Ndless rather than IP protection, because the C&D letter only targeted OS 1.1, despite all other OSes being very easy to find on TI-BANK.


The following were fake and pure satire, but still relevant to copyright issues:

-Playboy sues Ticalc.org for usage of the POTM acronym http://www.ticalc.org/archives/news/articles/1/14/14996.html
One of the first Ticalc.org fake news (red-border).

-DMCA takedown notice for using Keyfont in Omni logo https://www.omnimaga.org/news/ti-sends-dmca-takedown-notice-to-omnimaga-for-key-font-usage/
April Fools Day 2010. This one was a parody of the RSA key factoring incident, to make fun of TI actions against the TI community at the time.

-Metroid (MaxCoderz version) http://maxcoderz.org/forum/viewtopic.php?f=9&t=507
April Fools Day 2005. Joe Pemberton receives a cease and desist letter from Nintendo forcing him to stop development of Metroid for the TI-83/83+ to avoid legal action being taken against him. Thankfully this was fake (although the game never came out anyway), but it scared us enough to make me consider renaming Zelda: Dark Link Quest to "The Dark Curse". This April Fools joke is still mentionned every few year on April 2nd in the TI community.

After 9 years of developement, Pokémon Uranium is now released!



It's a fan game based on Pokémon franchise, featuring 150 new creatures, but with a twist: all of them are of nuclear type! During your usual gotta-catch-em-all quest, you will also have to save everyone from numerous nuclear meltdowns around. And no, sorry, despite being irradiated, our walruses aren't in the game. :P

Because of what recently happened to AM2R, we recommend that you take a small break from Pokémon Go,  hurry up and download this game before it's taken down:
