With just three staff members left and fear that I would have been forced to take a hiatus in a few months, the only way to continue keeping the website alive was to process into a restructure of our staff system. When I ran Omnimaga (which I founded in 2001), the main staff had some activity requirements to meet in order to ensure that we can maintain the website adequatly and keep its activity steady. That idea was transplanted into CodeWalrus when I co-founded it in October 2014. However, the TI community has mutated over the years, with changes in people's habits and priorities, reducing the amount of people who could contribute full time. In addition to that, some people might not necessarily feel comfortable with too many staff privileges. But then, what if those people still wanted to give us an hand?

This is why we are pleased to announce the introduction of a new staff group called Part-time maintenance and a position called Topic management! With the addition of the Part-time maintenance group, Streetwalrus is now able to stay in the team, at the server maintenance position! Besides those changes, Juju is now in charge of site funding. I am also now part of the Topic management group, although all its permissions are already available in the Forum maintenance group by default.

Now for the site itself, there have been quite a lot of updates since last week's events:
-There is now a forum navigation on the site front page portal, so you can access your favorite sub-forums faster! Thanks to SiNaN from SimplePortal website, this navigation is dynamic, so it will update itself automatically!
-When you register a new account, you can now directly choose to subscribe or unsubscribe from e-mail announcements and updates.
-It is now possible to switch between WIRC and OmnomIRC at will via your profile. Just join or leave the new group called "OmnomIRC mode" via the Group Memberships option and you're set. As always, you can also turn both off entirely by joining the "Disabled shoutbox mode" usergroup. #CodeWalrus is also reachable via EFnet, Omninet or Freenode as always.
-It is now possible to view all attachments of a topic in one page, via a topic list link or a topic view link at the bottom of the discussion.
-The forum rules now includes "disruptive behavior" as punishable offense, under rule #6
-The CodeWalrus store has been discontinued, as I am now out of the music business. The music link is now available as a new Downloads sub-menu in the top navigation bar and my entire discography will be available for free (without the bonus tracks) starting March 15th. This also ends the "My Little Activity: Posting is Music" promotion, which lasted for 2 years.
-The thrash bin sub-forum (where deleted posts land by default) is now visible to all members that have at least 1 post.
-You can now add your calculator collection above your signature (it doesn't take much space, especially now that CSS has been edited to shrink down signature size). Go to your profile to edit it.

And finally, we are working on our first newsletter, which will be sent via e-mail soon for those who have them enabled. The CodeWalrus newsletter will have an edition at the end of Winter, Spring, Summer and Fall and summarize major site events, updates and member projects and releases. Another surprise is coming soon as well.

Happy codewalrifying and thanks for the support! :walrii:

Calculators in General
People on Cemetech have analyzed TI-84 Plus CE Flash applications that Texas Instruments released a few days before. It appears that they contains a 2048-bits signature. The signature key is required to sign APPs and make them valid for use on the new ez80 calculator, and there is no sign that Texas Instruments have any plans to release a SDK to develop such software.

Since factoring an key this large is impossible with today's technology, could this mean that the TI-83 Premium CE and TI-84 Plus CE will be locked down against third-party Flash APPs and be restricted to only a few developers such as TI themselves? ASM programs are possible to write no matter the outcome of this, so 3rd-party ASM development on those new calculators is perfectly safe, but in some cases, choosing a 8xp ASM file over a Flash  APP is not the ideal situation, especially if TI decides also to add an executable code limit to that new calculator line, like the 8 KB limit on the TI-83+. Or could TI be planning a paid SDK? After all, back in the early 2000's, Flash APP development costed money before TI finally decided to make the SDK free of charge.

In conclusions, there is a possibility that for the TI-83 Premium CE and TI-84 Plus CE, we might be limited to the Asm() command to launch native language softwares.

Normally, as soon as a new version of Ndless comes out, a new TI-Nspire OS is announced shortly afterward. This is the case again after Ndless 3.9 release :P


It apparently comes out on March 26th 2015. Note that this OS drops compatibility with the grayscale TI-Nspire handhelds. However, the writing was on the wall for many years, as newer OSes kept growing in size, to the point where those using OS 3.9.1 would only have about 2 or 3 MB of free memory available for their programs once Ndless was installed. This means, on the other hand, that Nspire Clickpad/Touchpad users will be able to stick to an Ndlessable OS as long as their school allows grayscale TI-Nspire models!

The OS 4.0 announcement page advertises the usual anti-downgrade protection, although it also comes with many new features. Ideally, you should wait before upgrading until a new tool such as DowngradeFix is released, in case you want to downgrade back to OS 3.9.1.

According to a post on the HP Prime blog, it appears that this is the end of the line for the HP 50g calculator. Should the post reveal to be true, then HP will cease production of the HP 50g this year, to focus on the HP Prime. So after 15 years, the reign of the HP 49/50g series seems to be over.

This could probably have explained why there have been quite a few hot deals on the HP 50g lately, sometimes being offered for as low as $50. In any case, there will most likely be much more. It's a shame that the calculator has not taken off more than it did among developers, though, although it was very popular among engineers. Hopefully HP adds more engineering tool to the HP Prime firmware in the near future as a compromise to this loss.

Well, that was quick. As we said, we had some staff departures today:

- aeTIos lacks the time to do any admining, he therefore resigns;
- Streetwalrus don't have any time either, he takes a hiatus and may come back to the position at a later date.

So we're now in severe understaffing, as a result, we decided to close the site and made a closing post. However, as we decided the fate of the website, we concluded the best course of action would actually to leave it open for as long as I can afford hosting it... So it is my pleasure to welcome you back to CodeWalrus, but it's not without some changes:

- Juju is appointed Supreme Overlord of CodeWalrus (er, wait, that sound's a little scary... Let's just say I'm the head honcho here). I takeover the website and I'll pay for it with my economies and the free credits I have left in my account. If you feel generous enough to help, I take Paypal and credit over here :P

On the goal of the site, CodeWalrus gives programmers, artists, hardware and software hackers and the like a fun hangout to discuss together between geeks of projects in progress or just whatever, not just about TI, but yeah pretty much everything. The same rules applies under what's left of the administration, so nothing illegal, although I advise crossposting your projects on our friends at Omnimaga and Cemetech.

So, welcome back on CodeWalrus!
