You 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 closedIf you work at a desk all day, you should be thinking about your ergonomics.
Being comfortable while you work is important. It enables you to concentrate better, but more critically, it prevents you from injuring yourself. From Musculoskeletal to vision and hearing problems, yes, it is quite possible to injure yourself while working at a desk!
Comments closedI recently had someone ask me how to reorder the columns in a SQLite table. As you may be aware, the SQLite ALTER table does not have a lot of functionality compared to other databases and it certainly doesn’t have a way to do this.
Comments closedSometimes you’re going to need a data structure that is an array of classes and you’re going to want to sort them. The standard array Sort method can only sort simple types (Text, Integer, etc), so what do you do?
The traditional technique has been to use SortWith. You create a separate array of a simple type, populate it and then sort the temporary array using SortWith to sort the class array.
But there is an even slicker way to sort that was added in 2015 Release 3. You can now create your own custom comparison method and use that to sort the class. This custom method returns 0 if the values to compare are equal, a positive if the first value is greater than the second, and a negative value if the first value is less than the second.
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 closedMaybe you’ve heard the term SQL injection and how it can allow unintended database access. Here’s how a SQL Injection works and what you can do to avoid it.
1 CommentA 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 🙂
