Cemetech Contest #21: Holiday Celebrations
Published by jcgter777 on February 19, 2018 at 11:45:45 PM CST | Discuss this article (25)

Cemetech Contest #21, Holiday Celebrations, is all about the celebration of holidays! You can submit any program, in any language, for any platform. Holidays can be anything fairly widely recognized in any country, on any calendar (but please don't make up your own holiday); examples include Boxing Day, Valentine’s Day, Christmas, Hanukkah, Ramadan, Guy Fawkes Day, Bastille Day, etc.

This can be a program or game, in any language, for any platforms, celebrating a holiday. Be creative! You cannot copy or use part of any other programs, and no program previously published is eligible; this has to be entirely new. You can choose how exactly you celebrate your holiday. There cannot be any inappropriate content, or any content that discriminates against others. This contest is open to all Cemetech users, whether you’re a contestant or a voter. Voting will be done in a separate thread, and not in this one.

Submit your entries through email (contest at this website’s domain). Submit it in the same format as you would upload the file to the Cemetech archives. In the ReadMe, please include a contest specific section that includes the language it’s written in and the platform it was written for, and for the optional screenshot(s), include them in the submission itself. (If you need help getting screenshots, you should post in this thread). All entries must be in by 11:59 PM EST on the due dates outlined below. You may only submit one entry. (If you want to submit an update to your entry, PM either jcgter777 or jonbush, and re-email your submission)

Please create a thread to document your progress with the title format "CC21: ". You are allowed to receive help for this particular contest, provided that it is done publicly on either the forums, or on SAX/IRC. If you receive help from someone, make sure to give them credit!

Contest Timeline
The contest will begin on February 20 and end on March 20. *New* Voting will (hopefully) start March 21, and end on March 31.

If there happens to be a tie, 3 judges will be selected to break it. To be a judge, you cannot have been part of the contest, and you must PM either jcgter777 or jonbush with your application, including your background and why you should be a judge. The two (or maybe three) tied entries will be voted for by how well constructed they are, their program size and efficiency, and other factors.

Merry Christmas & Happy Holidays from Cemetech
Published by KermMartian on December 25, 2017 at 1:41:07 AM CST | Discuss this article (11)

Best wishes for a happy, peaceful Christmas and holiday season from the Cemetech staff to all of you and your family and friends! No matter what you celebrate (or don't), we hope you're able to take the end of the year to share some time with those who matter, reflect on the past year, and look forward to what's ahead. We particularly hope that even if you haven't had a chance to pick up your calculator or computer for a while to do some programming, that you take the opportunity to code up a project this winter.

If you need a little inspiration and Christmas cheer, here's a simple TI-BASIC program for the TI-84 Plus CE and TI-84 Plus C Silver Edition that will draw some Christmas greetings on your graphscreen. Just press [ENTER] after it pauses to end the program (and restore your graphscreen settings). If you're curious how it works and how to replicate it on your own calculator, just look in the attached topic, where we have the code and have challenged our members to provide the most accurate and concise explanation (yes, guys, that means you. Go to it!). Happy holidays!
