Doors CSE 8.2 Released
Published by KermMartian on May 19, 2015 at 11:14:45 AM CST | Discuss this article (6)
Since version 8.0 in November 2013, Doors CSE has been a mainstay on many TI-84 Plus C Silver Edition graphing calculators. This powerful shell is an App that sits on top of the TI-OS, allowing users to create and run powerful TI-BASIC and assembly programs while leaving the math and science capabilities of the calculator untouched. Over the year and a half since Doors CSE 8.0 was released, Patrick "tr1p1ea" Prendergast and I have been working hard to field feature requests and bug reports to improve Doors CSE. The release of Doors CSE 8.1 last July brought features like a special Apps folder that allows you to list and run Apps on your calculator, more xLIBC hybrid TI-BASIC functions, and many fixes for minor bugs. Now, I'm happy to present Doors CSE 8.2, the next iteration of Doors CSE for the TI-84 Plus C Silver Edition.
Doors CSE 8.2 focuses on improving Doors CSE's interaction with the TI-OS and with other Apps. But what exactly is Doors CSE 8? Doors CSE lists and can run all of your TI-BASIC and Assembly games and programs. It lets you organize your programs into folders, and archive, lock, copy, rename, delete, and hide them. It gives you extra features like an enhanced TI-BASIC editor, a clock, lowercase letters, and much more. Doors CSE 8 also contains the powerful xLIBC library by Patrick Prendergast and Celtic 2 CSE, which will make color TI-BASIC programs and games more powerful, useful, and fun. Here's what's new:

GraphnCalc83: A Review of a Faithful TI-83 Lookalike for iOS

I was provided a gift code and invited to look at a TI-83/84 "Work-alike" clone, GraphnCalc83, for iOS. The app is a universal binary so it supports both the iPad and the iPhone/iPod. I'll be reviewing this app on an iPhone 6 on iOS8, I did use it on an iPad as well.

The Bottom Line
The app is remarkable. The developer set out to create a graphing calculator for iOS that does its best to emulate TI-83 programs. While I can't recommend this app as a substitute for a physical calculator, due to the extreme differences and lack of complete support for TI-83+ programs. I can recommend this app to those that can't afford a graphing calculator and have a desire to learn coding but do have access to an iOS device like an iPod or iPad. I'd like to see iCloud integration to a degree, of course the more integrated the better but save/share and retrieve would suffice. The app doesn't even support "File Sharing" under iTunes, which means the only way to get your programs off and on your digital calc is to e-mail them. If File Sharing is supported, retrieving and sending programs would be as simple as dragging and dropping to/from the File Sharing window or clicking the appropriate buttons. If this application takes off it'd be amazing if we'd eventually see a centralized way to share programs with others similarly to ticalc.org.
In brief, it's not for everyone but for those with an iOS device and a need for a graphing calc with programming capabilities this is a must. You can check it out on the App Store here (USD $5.99).
Projects of the Month: April 2015

Another month has passed, which means it's time for our monthly Projects of the Month (POTM) article. The end of the academic semester, final exams and projects, AP exams, and SATs and ACTs are upon us, which means that people have been mostly busy with their education and jobs. Fortunately, some of our members have been particularly good at time management, juggling their personal programming projects in the midst of their other responsibilities. We're happy to showcase some of the most promising projects discussed on Cemetech this month.
Thanks to all of our members who have worked hard and shown us their creativity and perseverance this month. We can't wait to see where these and many other projects go in the coming month, as school winds down and free time ramps up. Who knows; perhaps a new Cemetech programming contest might even be on the horizon for the summer?

In 2012, Manning Publications and I published a book entitled Programming the TI-83 Plus/TI-84 Plus. It was the first (and only) book published that approached TI-BASIC programming as a useful skill as well as a way to learn programming techniques applicable to any language. I've since gotten much-appreciated positive feedback from readers about the material covered in the book, the many programs and games that it uses as liberal examples throughout, and how it teaches you to "think like a programmer". Although I hardly need to explain to the users of Cemetech how valuable knowing how to program can be, it's a great way to improve logic and reasoning skills in a fun, useful way, and provide a way to enrich other areas of STEM education. Unfortunately, a few months after Programming the TI-83 Plus/TI-84 Plus was published, TI Education announced the TI-84 Plus C Silver Edition, and two years later, we have the new TI-84 Plus CE, two calculators not originally covered in the book.
To address this omission, last summer I wrote a new appendix for Programming the TI-83 Plus/TI-84 Plus teaching TI-BASIC programming for the color TI-84 Plus C Silver Edition. At last, it is available as a free download from Manning Publication's website, and covers both the TI-84 Plus CE and TI-84 Plus C Silver Edition. In this appendix, entitled Programming the TI-84 Plus C Silver Edition and TI-84 Plus CE, you learn about programming for the new, larger homescreen, drawing in color on the graphscreen, and new commands available on the color-screen calculators. You'll explore a Snake game, a colorful hybrid TI-BASIC RPG game, and other examples as you learn to apply your TI-BASIC expertise to the color calculators. Please explore this free PDF, and I encourage you to buy the TI-BASIC programming book (available from Amazon and Manning) that it accompanies.
