Shadowing: You can’t always get what you want (or expect)

Shadowing is when a subclass defines a constant, property or enumeration (almost anything that is not an event or a method) that has the same name as a constant, property or enumeration (but not an event or a method) in the superclass. Generally the best rule is avoid using the same names for constants, properties and enumerations that the superclass has already used.

It’s 10 o’clock. Do you know where your time zone is ?

If you’ve worked with times and dates you know how much fun they can be especially when you deal with different time zones, differing Daylight savings time rules, if they observe DST and all the other intricacies tracking dates and times bring up.

And very often you need to save data to a database. So how do you store the data in your database so you can properly deal with it? And does your chosen database make that easy?

Guest Post: Xojo Networking by Eric Gibbon

Eric Gibbon has been a Xojo developer since 1999. When not heading up the Birmingham, UK Xojo User Group, you can find Eric at MacTasks.com where he offers consulting services and develops bespoke multi-platform multi-user databases for Mac, PC and the Web using Xojo.

Last year work wasn’t going so well, and I was feeling down. I had lost my “Xojo mojo”. As a freelance developer it can be hard to do everything you need to and it is easy to get bogged down. Sometimes you need a fresh injection of ideas and opinions, to see what other developers are doing and how they do it.

Xojo’s iOS Support and 64-bit

As you may have heard, Apple announced that as of February 1st, 2015, all new apps submitted to the iOS App Store must support 64-bit. It was already our intention to be in beta testing on 64-bit in that timeframe. However, our original plan was to support Linux first since more and more Linux servers now only support 64-bit. Instead, we will support iOS first followed by the x86 platforms.

How Vulnerable Is Google?

Google is by far the most popular search engine in the world with 71% of the market. While Google does many things, they make over 90% of their revenue from ads. In terms of revenue, that means that Google is a one-trick pony. If users switched en mass to another search engine, could Google’s ad revenue quickly dry up?
