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.

Download the APK directly to your phone from here: http://quantuminfinity.space/files/Walrifier.apk

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:

Art and Music
Some of you might be unaware of this, but I did not create two forums in the past, but rather three. Aside from Omnimaga group in 2001, its website in 2004 and CodeWalrus in 2014, I also founded TIMGUL in 2007, which stands for "The International Music Generator Users Lounge". Similar to Omnimaga's history of catering to TI-BASIC and xLIB programmers in its early days, TIMGUL did the same with the music making scene: From 1998 to 2004, Codemasters and Jester Interactive released the MTV Music Generator and Music 2000 software series for the Playstation 1 and 2, PC and even portable iterations known as Pocket Music for the GBC and GBA. Those softwares, especially the Playstation version of MTVMG and Music 2000, were basically the TI-BASIC of the music making scene, and TIMGUL was a community of users creating songs using those softwares.

Despite this console "game" series being discontinued three years prior the site's creation, the userbase grew to the point where the site hosted over 1000 songs and 12000 posts by the start of 2009. Unfortunately, drama then ensued, as well as multiple data losses, including corrupted song files and months of posts. Things stabilized in Early 2010 and TIMGUL enjoyed a revival under new administration, but after I stepped down from Omnimaga in 2011, the remaining administrators of the latter site chose to stop maintaining TIMGUL hosting and their backups became corrupted. Without warning, the site vanished for weeks, until me and Juju offered to host it. With all late 2011 and early 2012 songs data gone and its userbase being completely depleted, we chose to close the site and put it in read-only mode, until its new host also shut down in 2013. Afterwards the posts made between July 5th and April 24th 2012 were also lost.

Tonight, however, we are happy to announce that  CodeWalrus has put what's left of The International Music Generator Users Lounge archives back online. While it uses a different, read-only SMF database, you can now access TIMGUL like any other CW sub-forum or from the Downloads navigation at the top of each page. TIMGUL featured not only hundreds of songs made with the aforementioned vintage music making softwares, but also tutorials, help and support, contests and more. It is currently unclear if the TIMGUL database will merge with CodeWalrus, due to the challenges this would pose, so as a result, it is currently not possible to link old accounts and topics with new ones, but old TIMGUL users are free to register a CodeWalrus account and showcase their old or current work in our current music section, which we will expand based on future demand.
