Oregon Delphi User Group

For the last 10 years, a set of programming challenges has been produced on a daily basis from the beginning of December until Christmas. It is called Advent of Code, a name derived from the “Advent Calendars” popular this time of year where kids open a daily tab on a wall-hung calendar to reveal a surprise as they count down the days until Christmas.

Tonight we’ll look at a batch script that calls three command-line utilities which perform a lot of tedious work of migrating legacy Delphi 5 programs to compile under Delphi 12. The old code base uses the BDE and a lot of custom components; the new code uses FireDAC and Raize Controls and Quantumn Grid from DevExpress–a huge jump in functionality and improvement in user interface!

This month will be a light touch on a few of the recent features added to Delphi 12, including AI integration, Split Editor, Focus Mode, and WebStencils.

This month, we’ll meet at Gene and Sue’s home for authentic home-made pizza! They have a new address and would like a head-count, so watch your email and RSVP to that. If you want to attend, join our Groups.io mailing list and I’ll make sure you get an invite.

No meeting this month–enjoy a trip to the beach or mountains!

We’re taking it easy this month–no official presentation, no computers, just get together as friends and make sure we’re all surviving the summer heat!

Due to multiple conflicting schedules, we will not hold our regular Delphi meeting in Oregon this month. Enjoy the Juneteenth holiday and we’ll see you in July!

We have no official presentation this month. Instead, we’ll just discuss whatever topics that arise, possibly touching on RTTI and attributes.

We have no official presentation this month. Instead we’ll just discuss whatever topics that arise, like the recent release of Delphi 12.1, or why Lazarus produces much faster Linux code than Delphi, or where you were during the Eclipse on April 8? _UPDATE: The Main Topic turned out to be Source Control. A few notes were thrown together at the last minute and a good discussion ensued. Download: PowerPoint Slides (with links!

An interesting challenge was presented on multiple Delphi forums recently that grabbed my interest: read in a billion rows of data, collate and sort them, and print the summaries using only pure Object Pascal. The challenge started in January by an engineer’s blog post and has been expanded to Java, Go, and even SQL! For Delphi and Free Pascal, there’s an open source project and there’s an active discussion on Discord.
