Rosetta Code Mediawiki and Wordpress installs have been updated to latest stable versions.  For the curious, the wiki database backup weighs in at 129MB.  Please email me if something's broken.--Short Circuit

## Maintenance

The Rosetta Code wiki and blog will be going down Sunday, December 28th for maintenance and upgrades at 1AM Eastern Time.  Hopefully, the down time will be brief.Short Circuit

## Weekly update

ActivityShinTakezou is a new user who has been adding examples in a couple of different languages (mostly C and Objective-C). Rahul added a lot of Icon examples (Icon is new to RC, see below). C and Icon received most of the new examples this week.New Tasks and LanguageMore image-related tasks have sprouted up:
Other regular tasks have also been created:
• Trial factoring of a Mersenne number -- An algorithm using binary conversion to see if a Mersenne prime candidate is composite.
• Yuletide Holiday (most of the edits near the end of the week) -- A task which asks the programmer to find the years in a range where Christmas falls on a Sunday. This task was created to complete our task alphabet, and even though it's a little bit of a stretch, we'll go with it.
Icon came to RC this week and already has more than 20 examples written for it. It looks a little like Pascal to me, but with some extra "new language"-type features like the swap operator (:=:).Still NeededMore general volunteers for the admin assistance call. A list of jobs should be coming soon. It's being made by the people who do the admin work right now, but the reason they're calling for assistance is that they're too busy, so it may still be a little bit until it's finished. The list will probably include jobs as simple as spam removal and as interesting as Bot Master.

## Weekly update

• Knapsack Problem -- a classic computer science problem to determine the best total value of items that will fit in a knapsack.
• Top Rank Per Group -- a database-ish task to find the top N rows in a table based on a column.
• Palindrome -- write a function to determine if a string is a palindrome (case-insensitive).
• Constrained Genericity -- a language feature demonstration task, show how to put some rules on generic classes.
Here are the image processing tasks:
A task beginning with Y is still needed to complete the alphabet.Still NeededWith these new tasks come opportunities for new examples. Don't forget about the old tasks, though. Check through the task category (organized or unorganized) for tasks that you think you can do, not just new tasks.
