(Digital) photography, F-stops and polarisers

Posted by jpluimers on 2025/03/24

My filter removal tool broke, so while I had new ones on order, I had to figure out how many F-stops I would need to compensate for especially because I would be shooting during the evening.

Here are some links that gave me an impression:

Don’t you love the accessibility (a11y) awareness of people that put tables as images on their web-pages? The last link above did (see the image on the right below), I don’t: I love plain HTML with plain old rules and left-alignment content when it makes things more readable, so I converted it into a plain HTML table (: Read the rest of this entry »

Wat zou de status zijn nadat ICTU 2,5 jaar terug een slechte Mijn PGB Portaal en migratie opleverde?

Posted by jpluimers on 2025/03/21

Ergens zomer 2022 werd het nieuwe Mijn PGB Portaal verplicht. Voorheen verliepen declaraties en dergelijke via een portaal van het SVB. Die was niet snel, had soms nukken, maar voldeed aan meer NORA richtlijnen dan het nieuwe portaal.

ICTU is een speler die exclusief op de overheidsmarkt functioneert, dus daarvan zou je verwachten dat die snappen wat NORA inhoudt en een goed product neer zetten.

Het tegendeel is waar: ik schreef in september 2022 een Twitter draad met veel screenshots over mijn eerste ervaring met het nieuwe portaal en de migratie van de onderliggende data waaruit het tegendeel bleek.

Ik ben benieuwd hoe de status nu is.

GitHub: creating a directory while adding on-line adding a file or uploading file(s)

Posted by jpluimers on 2025/03/20

Since git doesn’t have the notion of directories as entities, neither does GitHub.

This makes it counter-intuitive to add a sub-directory when creating a new file on-line in the GitHub web-UI or uploading file(s) there.

I wanted to do this as instead of taking the local route, it was easier to on-line add and edit [Wayback/Archive] GitHub – jpluimers/https-imgur.com-a-bmw-e61-remote-fix-sWdk0: Content from https://imgur.com/a/bmw-e61-remote-fix-sWdk0 for Wayback Machine archival.

The GitHub web-UI can indeed do this:

You can also do this from the git command-line, by adding an empty file in the directory first. By convention, usually a .gitkeep file is used for that though others use .gitignore files for it.

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

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:
