Oregon Delphi User Group

It’s time to get into some coding practices. This is the first in a series exploring the SOLID principles of software development. This month, we’ll concentrate on the Single Responsibility Principle. As time allows we’ll start looking at the “O” which stands for the Open/Closed principle. Many of us have probably used these principles even though we may not have had fancy terms like this in mind at the time. Hopefully we can help one another think about how we can make use of common sense principles like these in our own work.

Due to the weather, we’ll postpone the start of our SOLID discussion until March. For those who would like to join tonight anyway, we’ll have a small gathering at the usual space and time and let the conversation lead us where it may!

For the discussion tonight, we’ll briefly touch on the latest update to Delphi which was 10.2.2. Since it’s the first meeting of 2018 we will also focus on what we’re all doing with Delphi (if anything) and what kinds of discussions would be best to focus on this year. I don’t want to spend too much time talking about features that are hardly even marginally useful to any of us and focus on what is useful.

Just discussions among friends.

There’s a pretty cool framework in .NET from DevExpress called XAF. We’ll start out with some tech talk and see if there’s anything Delphi related that we’d like to discuss. Then demonstrate some of the cool features XAF has to offer and why some of the things it’s trying to do may become the norm over time in software development.

Tonight, we’ll just hang out and talk. If someone would like to demo something they’ve been working on lately that would be wonderful. If nothing else we can fire up Delphi and play with the new REST features they’ve been adding. It might be fun to have a small database and just explore questions we might have about this technology together.

The interest in Pivot Tables was high. We saw demos last month and talked about concepts. This month we’ll see some real-life examples. Additionally, you might just see a hover-craft as a side-line interest!

Ron will lead a discussion on Pivot Tables and show some examples with the DevExpress Pivot Table. It allows you to dump data so your customers can create them using Excel’s Power Pivot feature. PRESENTER Ron Grove has been in the IT Services area for many years but has become a superb programmer with a strong interest in a broad spectrum of technologies including Delphi, .NET, and mobile.

This month, among other subjects, we’ll be looking at RAD Studio 10.2 Tokyo. There’s a possibility of other subjects being brought to the table, but you’ll have to be there to find out! PRESENTER Ron Grove has been in the IT Services area for many years but has become a superb programmer with a strong interest in a broad spectrum of technologies including Delphi, .NET, and mobile. His career has recently taken an interesting turn for the better.

Have you ever heard the phrase, March is for Makers? With the rise of inexpensive and easy-to-use micro computers, people are enjoying the hobby of making all kinds of gadgets themselves. Arduino and Raspberry Pi are two of the most popular names in the maker space. So what does this have to do with Delphi? Nothing necessarily. However, some of our members have shown how to connect and control small devices with a Delphi program.
