Want to see how easy it is to make an iOS app with Xojo? Check out Xojo Draw in the App Store. Released last week at the start of XDC 2016, Xojo Draw is an enhanced version of the Xojo Doodle sample project that is included with Xojo. Working on both iPhone and iPad, Xojo Draw lets you draw with touch and save your creations to the camera roll or send to other apps.

I’ve ran into PostgreSQL case sensitivity myself before and I’ve seen it come up on the forums, so I thought it might be a good thing to bring up here.
Sometimes you hear that PostgreSQL is case-insensitive, but it isn’t really. What it actually does is convert your SQL to lowercase by default. So take a look at this SQL:
SELECT FullName FROM Person
This gets converted to:
SELECT fullname FROM person
That is nice if you happen to like to write your queries with mixed casing.

In this Xojo tutorial we will see how simple it is to make an iOS App that shortens an entered URL using the public API of Bit.ly. We will use our own subclass inherited from Xojo.Net.HTTPSocket, and the Declare statement in order to use some functions and methods found on the native Cocoa Touch API. In fact, the use of Declare is mandatory because with the new Xojo Framewok we don’t yet have access to the EncodeURLComponent function available with the old framework. This one is a big help in substituting any ilegal character with his hexadecimal value for the final URL’s composition.

My kids both recently finished their summer band camps. My son plays the trombone and my daughter plays the saxophone and trumpet. As one of the instructors at band camp said, even if you don’t take up a career in music, learning and playing music exercises important parts of your brain that are useful for learning other things. In fact, some have wondered if learning music helps with math skills.
I think the same thing can be said about coding. In fact, there is research that found students with computer programming skills scored higher on cognitive ability tests than students without any programming skills. Coding teaches you skills that are valuable even if you don’t plan on being a professional software developer. Being able to code means utilizing incredible attention to detail and thinking about problems abstractly, useful skills for anyone – student or professional.
Remember, Summertime isn’t just an opportunity for the kids to learn new things. You’ve still got a month of Summer left, plenty of time to expand your own skill set. While the kids are at band camp or swim camp send yourself to programming camp from the comfort of your air-conditioned home.

On the Xojo forum a user asked if there was a way to execute a formula in Xojo. As pointed out in the conversation, Xojo includes an Evaluator example that does exactly that. It uses XojoScript and I thought it might be interesting to show how it works.
