Have you ever needed or wanted a populated sample database with several related tables to play around with? Perhaps you are learning about databases and database design or perhaps you want to try out a new tool such as Xojo but want a pre-build database to start with.

The TSA was recently in the news for paying tens of thousands of dollars for a seemingly simple iPad app to direct people to different security lines. Now we obviously don’t know everything the app does, but it sure seems like it would be pretty straightforward to make such an app, especially using Xojo.
Comments closed“Retina” is the name for high resolution screens on Mac and iOS devices while “HiDPI” is the Windows equivalent. For simplicity, I’ll use HiDPI (which really is the universal technical term) for the rest of this blog post. Now that we have HiDPI support in Xojo, if you app doesn’t use any pictures, you can simply open your project, click on Shared under Build Settings and turn on the “Supports Retina/HiDPI” option. That’s all you need to do to have a HiDPI version of your app!
Having said that, if you are creating or using pictures in your project, there may be a few adjustments you’ll need to make to your code. A little over a year ago the process of making sure we had all of the necessary graphics together to build a Retina/HiDPI IDE was added to my to-do list. While 95% of the icons created for the Xojo IDE in 2013 already existed, most of the graphics that made up the IDE itself did not, and the IDE itself needed a bit of an overhaul to get it ready for the big change, both in graphics and in code…
2 CommentsYou don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.
My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.
Comments closedOn Monday February 29th, the Raspberry Pi Foundation announced the new Raspberry Pi 3. This updated Pi has some significant improvements over the Pi 2, including:
- A 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (~10x the performance of Raspberry Pi 1)
- Integrated 802.11n wireless LAN and Bluetooth 4.1
- Complete compatibility with Raspberry Pi 1 and 2
That last bullet point is notable because it means that Xojo is also fully compatible with the new Raspberry Pi 3!
Comments closedA couple years ago I wrote a post about Going Rogue with Xojo. It proved to be rather popular and I got some great stories back from how people were able to use Xojo in their organizations.
Comments closedHow do you format and organize your code? I’m here to tell you that your way is wrong and my way is right 🙂
Comments closedIn the blog post Smartphone Encryption is a Red Herring, I pointed out the folly of requiring an encryption back door for the Good Guys to use. So the question arises- “What can be done? If we don’t want a global encryption back door that can be used by anyone, can we still track the Bad Guys?”
The answer is yes. There are plenty of options that don’t require a global back door. I’m not passing judgment on whether these are inherently good or bad options, just that they are available when there is a reason to track a Bad Guy.
