Advanced Application Signing – Milan Adamov

As developers of applications that run on Macs and Windows machines, we have to play by the rules of each of the platforms. Both operating systems are constantly improving security, and part of tightening down the system is requiring applications to be signed by registered developers. This way the OS can deter potentially harmful softwares from being downloaded or running on your system.

Application signing is close to be mandatory on macOS already, and Windows is becoming stricter with every release. Apple made the signing process pretty straight-forward on macOS and really cheap. Microsoft is catching up with the introduction of Azure trusted signing about a year and a half ago. Both of them offer a convenient signing process that can be easily automated.

In this demo, Milan Adamov will demonstrate how can you setup and use both of the singing services manually on a local computer and as well via Github actions worklows. It might be worthwhile to review his last demo to be able to follow this one in step… Master Action Building with GitHub – Milan Adamov

4D AI Platform – the Future Is Now – Ricardo Mello and Mathieu Ferry

4D has been valued as a Rapid Application Development tool since back in the 80s giving developers the capability to get a working prototype of a technical solution in front of prospective clients quicker than the competition. The platform gives you the ability to deliver modern, performant applications that integrate well with other systems without needing to write low level code for complicated system libraries.

Today 4D continues keeping developers in front of the pack with its focus on AI in 4D 21. With the release of the component AI Kit, 4D is making it easier and easier to deliver remarkable AI powered functionality to your users without you needing to go back to school for another degree!

Ricardo Mello and Mathieu Ferry will join us in this meeting to demo new and upcoming AI features available in 4D today and even more with 4D 21.

Cron – It’s about time! – Koichi Harada

Cron – It’s about time! – Koichi Harada

4D apps are running 24 hours a day/ 7 days a week all over the world, and often they need to execute tasks on a regular basis in the background without user or administrative action. These tasks could be related to maintenance, reporting, importing, exporting, notifications, data checks and fixes, date related events, and so on. The tasks are as varied as the applications themselves.

I, for one, cannot operate without a schedule, and neither can my applications. Many of us have written our own variety of scheduler modules, which normally have a control process running around the clock that checks a list of jobs and fires them off when necessary. This is a very common need, which deserves a very common solution.

Release the daemons! Koichi Harada’s open source Cron component provides a modern, class based, simple yet powerful solution for all of your scheduling needs!

List As Objects – Bruno Raeymaekers

Special Topic:
List As Objects – Bruno Raeymaekers

The ability to use lists is an important tool in the hand of every software developer. In it’s purest form, the concept of lists is simple: you have a “subject” (the list itself), and you can relate “topics” (list items), or even other “subjects” (in case of a hierarchical lists) to it.

But what if you need something more? What if you could enhance a list item with an unlimited number of attributes to give it more meaning? What if you could add more potential to the list itself by adding an object to it to capture related data to be used in your project?

Special Topic:
Beautiful Documentation Made Easy – Jim Kerver

Inspired by the 4D Method presentation Building developer.4d.com, let’s dive deeper into Docusaurus and how to set up a documentation website for yourself.

Documentation is always a chore, but by using Obsidian and Docusaurus, it can be made beautiful and maintained practically by using Git. Check out the example website here.

In this presentation, Jim Kerver will take you through the steps of setting up your own Docusaurus website, customize it for your brand, and deploy it for free via GitHub Pages.

Special Event! – Visual Studio Code for 4D Developers: Code, Debug and Copilot – Mathieu Ferry and Damien Fuzeau

Special Event!
Visual Studio Code for 4D Developers: Code, Debug and Copilot – Mathieu Ferry and Damien Fuzeau

4D has always come with a very capable Code Editor in its Integrated Development Environment (IDE) that has a wide set of features for highly productive application development such as intelligent code completion, code navigation, debugging, searching, macros, and more.

Since the introduction of Project Mode, where each piece of code (method, class…) is stored in external text files, 4D has been adding features to support using other code editing environments such as Visual Studio Code (aka VS Code.) VS Code is an extremely popular, free IDE for Windows, Linux, macOS that includes embedded version control with Git, debugging and many useful extensions that add functionality. You can super-charge your 4D application development capabilities by leveraging some of the features available in VS Code but not yet in the 4D IDE, like integrated source control and GitHub Copilot.

In this 4DMethod special event, Mathieu Ferry and Damien Fuzeau join us to demonstrate how to use VS Code in your 4D application development. This will be a great opportunity for the 4D developer community to give feedback directly to 4D about current integration with VS Code and to discuss upcoming potential features that 4D is considering for its IDE.

Enable Data Change Tracking – Keisuke Miyako

Special Topic:
Enable Data Change Tracking – Keisuke Miyako

I often hear myself repeating… “Syncing is hard.” Data replication is a common requirement for a variety of different application architecture requirements, be it offline access for mobile apps, offloading data access away from your production server for security reasons or reporting needs, or even for load balancing in a high traffic environment. It can be very challenging to replicate every single data update into a separate datastore. Thankfully we recently got some new tools for making this problem easier to manage!

Native data change tracking is a relatively new feature in 4D, being included in the 4D 20 R3 release. So many new features become available with each R version that you might have missed this game changing update. And it is relatively easy to set up once you know how it works.

At long last, Keisuke Miyako will join us to present this not-to-be-missed demo. Keisuke is one of the most prolific 4D developers ever, with over 600 open source projects in his GitHub repository. In this session, Keisuke Miyako will explain how the feature works, how it differs from journaling or mirroring, how to manage collisions, and more.
