This years WorldWideDeveloperConference WWDC 2011 sould out within 8 hours. So, bad luck if you’ve been on a transatlanic flight at that time. Today, the lucky ones of the iOS & Mac developer community, who managed to get a ticked this year, gather at the Moscone West Center in San Francisco. Probably, Apple will share the videos of all of the WWDC sessions for free with their registered iOS & Mac developers, like they did last year. And even if the Cupertino guys won’t stream Steve Jobs keynote live, we’ll get a video stream short after the event. For real live coverage we can rely on the all those people blogging from the keynote. The keynote begins at 10:00 AM PST (07:00 PM CET) and there are a lot of things to cover: The next version of Mac OS X called Lion, the next version of iOS for iPhones & iPads and Apples new cloud service iCould.

Finally, Apple introduced native Git support in Xcode 4. Git is now the standard version control system you can use within Xcode. The Apple engineers did a great job in integrating Git into Xcode 4 … but there is room for improvements Tools like gitx still are essential for me to keep track of all the branches in the Git-repository.
If you want to use Git as the version control system for your Xcode projects, you definitely should use a specific .gitignore file to keep your Git-repository clean.

That’s the content of a Xcode4 optimized .gitignore text-file:

Sure, the iPhone can not cope with the image quality of a good digital camera … but it’s great for snapshots and ShakeItPhoto- or Hipstamatic-experiments. That’s why I’m collecting a lot of pictures on my iPhone from time to time. Sometimes I sync the pictures with iPhoto. But I’m not always using the delete-after-import feature. The current version of iPhoto does not have any problems with that if you use the “Hide Photos Already Imported” option: iPhoto just ignores the old photos and only downloads the previews of the new ones in the import section.
But there is no way to delete all or a selection of these old photos in iPhoto, iTunes or on the iPhone. But the only solution to delete these photos one-by-one on the iPhone is not working with hundrets of photos. So, what to do?

Every Mac ships with a standard Apple utility which helps you out It’s called “Image Capture” (or on German Mac OS X systems “Digitale Bilder”). This utility shows all images on the iPhone. You can select all or only a selection of these pictures and you’re able to delete them right away! Here is how to:

1. Connect your iPhone via USB with your Mac.
2. If iTunes or iPhoto starts, wait for the sync, and press the iPhone-disconnect button within the itunes window. Make sure, that you quit iTunes and iPhoto.
3. Open “Image Capture” from the applications folder.
4. Select your iPhone in the left column and a list of the iPhone photos will be displayed on the right.
5. Select the photos, you want to delete – or select all pictures by pressing command-A.
6. Now press on the red delete button just beneath the list. If you’re sure, that you want to delete the pictures you can confirm the deletion. WARNING: You cannot recover the deleted photos – so be sure, that you imported them to iPhoto before!

The automatic update function of WordPress makes it super easy to update the wp-installation. Most of the time
If there’s an update which is not working as requested, you do not need to switch to manual mode and search for your FTP-access on the server immediately. A small trick helps you to get rid of the “Fatal error: Out of memory”:

1. Before you start updating WP … don’t forget database update!
2. Deactivate the active WordPress-Plugins in the admin section under “Plugins”.
3. Now, you can start the automatic update of your WordPress installations.
4. Now it’s possible to reactivate the deactivated plugins: Select “Plugins” and “Recently Active”.

The WordPress community and your own blog readers will enjoy a new level of cyber secrity

Great to see Steve Jobs on stage again. The presentation is about three blocks of information:

1. The market: Steve presents some amazing numbers … 15 Million iPads sold, 100 Million iPhones sold, 100 Million iBooks downloaded, 200 Million Accounts on the iTunes/AppStore/iBookStore with credit cards, $2 Billion payout to AppStore developers.
2. The iPad 2: Apple listened to their customers and integrated most of the features iPad users are demanding. But they also kept the prices and the battery life. The new A5 Dual-Core CPU is up to twice as fast and the graphics performance up to 9x. With the HDMI-cable accessory, it’s possible to mirror the iPad 2 screen to a flatscreen or beamer. This is perfect for live app demos and presentations. The iPad 2 is now equipped with a front and a rear camera. The new design of the iPad 2 and the magnetic covers speak for themselves. The design team of Jony Ive did a great job.
3. The software: iOS 4.3 is shipping with a lot of improvements under the hood. By introducing iMovie and Garageband for the iPad Apple shows, that the iPad is not only a consuming device, but also a device to create things.

But I only can recommend to watch Steve Jobs, Scott Forstall, Randy Ubillos and Xander Soren on the Quicktime streaming video yourself. Sorry PC-folks: The streaming video requires Safari 4 or 5 on Mac OS X Snow Leopard or Safari on iOS 3 or later.
