Some notes on recursive lambda expressions in case I ever want to try this myself (spoilers: a lot of study time ahead; many of these links are not live any more)

Posted by jpluimers on 2025/03/20

A sidestep of the series around Writing a tool that restarts the Google Chat desktop app Window (and hopefully the Google Duo desktop app Window too):

Enumerating Windows and especially Child Windows is a recursive endeavour, so I wondered if it was possible to write a self referencing delegate, anonymous method or lambda in C#.

That turns out to be way more complicated than I hoped for.

Some notes below, as:

  • one day I might want to rewrite the core to use this technique just for learning purposes
  • finding these links was quite a bit harder than expected due to link rot often caused by missing redirects (especially on the Microsoft blog sites: for one as not all their blog members are still with them which means content got ditched, and also because they moved through a couple of blog platforms so the really old links to not redirect, not even while tracking them through the Wayback Machine, or the content is incomplete which is why all below links are both in the Wayback Machine and Archive.is)

Here we go:

Laurensvanrun/Delphi-Promises: Delphi implementation of promises for asynchronous programming.

Posted by jpluimers on 2025/03/19

On my research list after making this short note April 2024: [Wayback/Archive] GitHub – Laurensvanrun/Delphi-Promises: Delphi implementation of promises for asynchronous programming.

My first impression is that this might be on the same level of usefulness and influention as these two:

Writing a tool that restarts the Google Chat desktop app Window (and hopefully the Google Duo desktop app Window too) and some EnumWindows/EnumChildWindows tricks

Posted by jpluimers on 2025/03/19

Earlier this months I wrote Writing a tool that restarts the Google Chat desktop app Window (and hopefully the Google Duo desktop app Window too) promising I would rewrite the Delphi code into C# and integrate it into PowerShell.

This is the beginning on porting the basics of the Delphi code (which had a flaw!) to C# and contains EnumWindows/EnumChildWindows and error handling tricks and tips.

Ben Dicken on X: “You asked for it, so here it is. Visualizing CPU cache speeds relative to RAM. Cache optimization is important too!”

CPU Cache and RAM performance slowed down many magnitudes for better comparison

The graph was made using [Wayback/Archive] GitHub – d3/d3: Bring data to life with SVG, Canvas and HTML. :bar_chart::chart_with_upwards_trend::tada:.

The underlying data is from [Wayback/Archive] Memory Performance in a Nutshell.

It was kind of a follow-up on a similar animation for Memory lookup versus SSD read speed (links at the end of this blog post)

Enabling XML Auto Commenting C# in Visual Studio Code is in an odd setting (via Stack Overflow)

Posted by jpluimers on 2025/03/18

In Visual Studio Code I already had [Wayback/Archive] C# – Visual Studio Marketplace: C# for Visual Studio Code (powered by OmniSharp) installed in (through code --install-extension ms-dotnettools.csharp), and wanted automatic XML documentation comments generation just like Visual Studio does:

Ungendered writing – #awareness

Posted by jpluimers on 2025/03/14

Maybe the outcome of this research study is even more reason to promote awareness around ungendered writing.

In this world at large, inclusivity should be the norm and showing that in your writing should increase funding rates for science articles.

For my link archive: Counting the leading zeroes and ones in a binary number with C#

Posted by jpluimers on 2025/03/13

From a while back, but still interesting:

  1. [Wayback/Archive] Counting the leading zeroes in a binary number with C#
  2. [Wayback/Archive] c# – Getting the number of leading 1 bits – Stack Overflow (thanks [Wayback/Archive] Barry Kelly and [Wayback/Archive] SoapBox)

Especially the first link explains the algorithm very well and is similar to links referred to from the Stack Overflow question as it is based on counting ones (and leading ones are basically leading zeros but bit-inverted).

It also explains a cool thing for leading zeros: modern CPU have instructions which .NET Core.

Delphi and SonarQube: great open source additions in the last few years.

Posted by jpluimers on 2025/03/12

In the past, I mentioned that the open source SonarQube by SonarSource was on my “research list” in a few blog posts* as I am a fan of static code analysis **, and now it is time to amend them with the current state for using it in Delphi.

SonarSource products

  • SonarQube Server (formerly SonarQube) is an open core product for static code analysis, with additional features offered in commercial editions.
  • SonarQube Cloud (formerly SonarCloud) offers free analysis of open source projects.
  • SonarQube for IDE (formerly SonarLint) is a free IDE extension for static analysis.

For more history on them, see [Wayback/Archive] About – Sonar and SonarSource | Sonar.

Delphi integration

There are two open source integrations: for ConarQube Server, and Linting, both maintained by the same company ([Wayback/Archive] IntegraDev · GitHub):

I was today years old when I found there is a shortcut to switch to the Terminal tab in Visual Studio Code

Posted by jpluimers on 2025/03/12

Boy, I always to the Ctrl+Shift+Space on Microsoft Windows (or on MacOS Command+Shift+Space) detour to switch to the Terminal tab in Visual Studio Code

So I was amazed to find the shortcut inside the first bullet in the Google Search quote of the first result at [Wayback/Archive] vscode terminal open new terminal – Recherche Google:
