We've started up a Twitter account for Lazy Joe's Warehouse

Last week I created the Twitter account [@LazyJoesApp(https://twitter.com/#!/LazyJoesApp) for our iPhone puzzle game Lazy Joe's Warehouse and I'm looking forward to interesting conversations with iPhone gamers around the world. If you're a fan of the game, follow us for some daily challenges!

Personally I'm pretty new to Twitter so I'm looking forward to learning more about it.

iOS dynamic image loading

When developing iOS apps you often find yourself wanting to fetch images dynamically from a server rather than having them all shipped in the app bundle. For this task I usually use the [EGOImageLoader](http://developers.enormego.com/code/EGOImageLoading) library by [ENORMEGO Developers](http://developers.enormego.com/). It handles the downloading and caching of images, and if used for instance in a UITableView it changes download priority in the fly to prioritize images in the UITableViewCells currently displayed. It also uses the delegate pattern so you can easily add whatever adjustments you need for your particular project.

Apache Drupal XML with statistics - High load on events

Today we had another event with Ski Classics. And as usual we find ourself having  performance issues. We have XML files of statistics showing stats of the race at the same time we are streaming the event. The streaming is done by a third part and we just embed a jw player for flash and html 5 playback for iOS support. The problem is that the statistics of the race is updated all the time and is delivered to us as xml files. We are currently reloading the statistics every 10 second for the race statistics and every 150 second for the over all standings. We relod the part of the page with using javascript. This causes the server/apache to use a lot of memory even on small number of users. We are dealing with this problem currently by downloading the part of the page evert 5th second and then store it as clean html. This makes sure that the users only view fixed html version of the page and decrease the server load a lot (have occasionally seen 8 processors been reduced from 99% usage to 10 %). I do this my using the watch command (watch -n 5 ./script.sh) on a script. The script first sets the file and then reloads it with wget. If anyone have any other solutions please let me know.
