Date: 14th Nov 2022
- Delphi, Linux, Daemons and Windows Sub-system for Linux (WSL) vs VMs for testing – Dave Martel
A Delphi Linux project developed to aid data transfer from old legacy systems that have been isolated from the main network for security concerns through a Linux proxy.hes of computations by offloading the work onto the GPU.
- Microsoft Licensing & Microsoft Accounts – James Daniel
This session explores the current status of Microsoft’s free upgrade programme for Windows 7, 8 and 8.1 to Windows 10. It also illustrates some ways of managing Microsoft Digital Licences for Windows 10 by using Microsoft Accounts in combination with Windows 10. Some of the material relating to Microsoft Accounts may also apply to Windows 11.
- Issues with MTD Project, update – Ian Hamilton, Russell Weetch
- Open Mic for Mote /Fleck/Gobbit/Tools / Tricks / Ticks
Date: 12th Oct 2022
- A quick introduction to GPU compute work – Dave Capps
I will cover a very quick high level history of GPU computation, then show with code examples how to accelerate large batches of computations by offloading the work onto the GPU.
- A potential replacement for Slack – Ian Hamilton
A quick look at a an attempt to build a replacement for Slack, or the bits of Slack the group uses. One way of doing it, includes (hopefully) WebCore and VCL clients, a WebBroker REST API and a Firebird database.
Date: 13th Sept 2022
- Network Boundary Security – Rob Lambden
- Memory Management with Managed Records – Conrad Vermeulen
Date: 11th July 2022
- Lets do some pascal scripting, as used in our ETL (Exchange, Transform, Load) tool – Lorenz Wolf
Will look @ FastScript Scripting library for Delphi 7-XE8, C++Builder 2005-XE8, Embarcadero RAD Studio 11 and Lazarus from Fast Reports .com
How we have used it in our ETL tool; for lack of a better name ritTWDC.exe (r-retail it – infotechnology T-two -W-way D-data and C-converter. )
Explain how we use it and go through some simple scripts to some more complicated ones using OLE/COM to bind with other useful components.
One of which is WINSCP – windows secure copy to provide easy access to a smorgasbord of communication and file transfer protocols.
- Ecommerce workflow example – fetch xml order files SFTP, transform to alternative XML format , call Soap Webservice/s (Web Request), remove processed files, Notify via Email if error conditions occur. Pop original order XMLS into MSSQL database.
- Simple Emailing or data conversion
- Using commandline variables/ parameters in the script to allow for more integration options.
- Custom Plugin dlls to extend or bespoke functionality
- A quick look at Lazarus – Ian Hamilton
An intro to the Lazarus IDE and a discussion of some of the things that I have found it can do and cannot do. For those who cannot afford to keep up their Delphi maintenance, a look at the kind of projects for which Lazarus is, or might be, a viable alternative.
- Introduction to Network Boundary Security – Rob Lambden
Code-free (code to be covered in a later session if there’s still sufficient interest!).
Background to IP layer security, role of the boundary, networking stack on Linux (and maybe Windows … probably not).
Tools to keep your boundary secure and how to leverage them.
Future session to include the software design and implementation code for agents that are used to respond to issues inside the network and implement blocks at the boundary.
Date: 15th June 2022
- Integration testing with WebMocks for Delphi – Richard Hatherall
- Continuation of – Anonymous Methods with and without Delphi – Dr Kevin Bond
- Toolkit Corner, to include:
- Beep and Compilers – Adam & Brian Long
- MMX Refactorings – Dr Kevin Bond
- Bookmarks – Paul Woodhams
- Linker Switches – Mark Jacobs
Date: 17th May 2022
- Guest Speaker: Delphi memory management – Dalija Prasnikar
Memory management. One of the most basic parts of software development, often kept on the side even though it has the most profound effect on how we write our code.
Managing memory is both a trivial and a complex task. Trivial, because the basic rules are rather simple and straightforward. Managing a few references, when you know the rules, is a piece of cake. The complex part comes from several things. First, even though each rule is simple, there are many of them, and knowing and remembering them all is a challenge. Next, combining the rules makes even more rules. Some combinations work, some don’t, and while this knowledge can be extrapolated from each single rule, it is easy to overlook some important fact that can lead to disaster. And at last, complexity arises from all the pieces of code sitting together in one place, obscuring each other.
What is important to remember is that managing memory requires following the same simple principles, regardless of the size of the codebase. Divide and conquer is the winning strategy. If each small, self-contained piece of code, where managing memory is trivial, is done right, then all the pieces can work together in harmony.
- Anonymous Methods with and without Delphi – Dr Kevin Bond
Talk will cover background to anonymous methods, the functional programming style, higher order functions and closure, how Delphi implements anonymous methods, comparisons will be made between Delphi, PascalABC.NET, Haskell, Python and C# via example programs that use anonymous methods/functions/procedures and fluent interfaces.
- Speech APIs in Delphi and C++ Builder – Mark Jacobs, Richard Hatherall, Ian Hamilton
A demo of using a basic API from MS in BCB5 (MJ), Polly in AWS (RH), and 2 short demos, at 5 minutes each, one on Azure and the other on TMS (IH)
Date: 11th April 2022
- Guest Speaker: RAD Studio Open Tools API – Glenn Dufke
Have you ever wondered how you can extend the RAD Studio IDE yourself? Do you have an idea for a helper utility which could ease daily development?
Then the Open Tools API is the gateway to extend the IDE!
Embark on a deeper dive into what the Open Tools API is and how you can work and access many IDE elements, including the new Welcome Page API.
We’ll code a Welcome Page plugin and look at how you can access the editor buffer.
Feel free to prepare questions if you have specific ideas and want help to get started.
- Nugget: Chasing down a bug – Jason Chapman
A user was reporting that a report was missing rows
- XML Import Export – Rob Lambden
Date: 16th March 2022
- Server Load Testing – Simon Hooper
We have 90,000 staff, does it scale? asked a potential customer. How we measured how many Reports Per Minute (rpm) that our Wise Eyes server can deliver. Concept, code, live demonstration and results. If time allows an introduction to the issues of high capacity.
- Guest Speaker: kbmMW SmartService and kbmMW SmartBind – Kim Madsen
- Embarcadero webinar: “What’s Coming in RAD Studio Alexandria”
Date: 15th February 2022
- React framework – an introduction – Will Watts
- Nugget: Automating Google lookups – Mark Jacobs
I gave a talk on Google lookups before, but they seemed to have clamped down on the methods I used, and they no longer work on Google. I discovered a way to circumvent these measures, using Google’s image search. I propose to talk about how I do these image lookups, using a random web page selector I have developed at https://jacobsm.com/randword.htm
- InterBase and InterBase with IBX – Jason Chapman
The title is pulled directly out of a request from MartinB in the group. I no longer consider myself an expert at the cutting edge of what is available with Interbase, but I can cover the basics and provide a platform for others to chime in with their experience (relevant experience of course, I’m not going to entertain “I wrote my own DB engine”). So this will be an introduction to Interbase and the cross over with Firebird, then specifically talking about IBX, which is the road less travelled these days as most are likely to be using Firedac
Date: 17th January 2022
- Developing a full XData – WebCore stack – Russell Weetch
This session will show the work doen to create a fully functional application using the TMS XData server and WebCore client library.
- Buying and Selling a Software Business – Rob LambdenWhat’s involved in buying and selling a software business, how much a software business is worth, how the deal can be packaged.
- The AWS SDK for Delphi – First look and discussion about evolution and adoption by Embarcadero – Richard Hatherall
