A while ago I bumped into the error [Wayback/Archive] .net – The library hostpolicy.dll was not found – Stack Overflow (thanks [Wayback/Archive] Nate Barbettini for asking) which prevented me to debug in Visual Studio Code, but none of the answers applied to my case, so I added this one: Read the rest of this entry »

Quick batch file hack to download a file calling PowerShell to do the heavy lifting

I needed this download-file.bat a while ago, but forgot how I found out.
It’s in this gist too: [Wayback/Archive] Quick batch file hack to download a file calling PowerShell to do the heavy lifting.

PowerShell: playing around with Get-PnpDevice filtering with -Class and -Status
Posted by jpluimers on 2025/07/29
I while ago I was playing around in PowerShell with Get-PnpDevice (which got introduced in Windows 10 and Windows Server 2019):

Overlay of commands / shortcuts / keys pressed – Screencast Mode · Issue #981 · microsoft/PowerToys · GitHub
Posted by jpluimers on 2025/07/23
This is a reminder to check if this below late 2019 proposal inspired by Visual Studio Code Screencast mode¹ already made it: [Wayback/Archive] Overlay of commands / shortcuts / keys pressed – Screencast Mode · Issue #981 · microsoft/PowerToys · GitHub which mentions some tools that can already do this
Here is a list of FOSS apps that currently do this (sorted by stars):
- github.com/Code52/carnac – Unmaintained, does not work on most applications
- github.com/Phaiax/Key-n-Stroke
- github.com/marius-sucan/KeyPress-OSD – Commercial version available
- https://github.com/Jagailo/YetAnotherKeyDisplayer
- mulaRahul/keyviz – Quite new and looks good
To add to this list (unsorted):
- github.com/nutti/Screencast-Keys – Blender addon
- github.com/AxDSan/KeyPose – free alternative to MousePosé for Windows
- github.com/keycastr/keycastr – macOS only
In the meantime, I am using Key-n-Stroke as it is the only still supported one I found that is easily turned off/on when typing sensitive content like passwords:

Alan Turing Wrote Object-Oriented Code In C And Ran It On BEAM – De Programmatica Ipsum
Posted by jpluimers on 2025/07/16
I originally missed this as back then I was in the midst of managing trouble in my parental family, unaware I was already having rectum cancer. Then things went fast, not even including the Covid-19 years, so I was glad last year I got reminded of this mid-2019 article:
[Wayback/Archive] Alan Turing Wrote Object-Oriented Code In C And Ran It On BEAM – De Programmatica Ipsum writes a lot of interesting things on programming paradigms, starting with
In his rare 1994 book “Object-Oriented Programming In C” Axel Tobias Schreiner explains how to do inheritance, class methods, class hierarchies, and even how to raise exceptions using nothing else than pure, simple, pointer arithmetic-filled, ANSI C.
then arguing basically most of not all modern languages share the majority of programming paradigms and all these paradigms are repeats of the past:
These days, we are using the offsprings of multiple programming paradigms having unprotected sex with one another in a thoughtful orgy. PHP, C#, Perl, C++ and even Visual Basic have all closures, lambdas or anonymous functions now. F# and Scala can instantiate any class included in their corresponding vendor-provided frameworks. JavaScript implements functions as objects with a single method.call(). Haskell comonads are actually objects. Swift 1.0 implemented instance methods as curried functions.But none of this is new. Smalltalk, arguably the precursor of object orientation, hadcollectandselectmethods which were the grandparents of our more commonmapandfilterfunctional friends.
What sets modern languages apart is that they the majority covers all the paradigms you might need, just differing in how well they support the paradigm-du-jour.
It means programming language wars should have been a thing of the past for about two decades now.
Please let that sink in.
Oh: if you look for that ANSI C book, here it is: [Wayback/Archive] https://www.cs.rit.edu/~ats/books/ooc.pdf [Wayback PDF View/PDF View]

badamczewski/PowerUp: ⚡ Decompilation Tools and High Productivity Utilities ⚡
Posted by jpluimers on 2025/07/10
Below is a really cool tool-set for Visual Studio Code of which its development started when I was recovering from life-saving bowel-surgery during the series of procedures to get rid of my metastasised rectum cancer.
It supports decompilation of various languages (.NET C# and F#, GO, Rust and clang) into either x86 assembler or IR (Intermediate Representation, on the .NET side often also called IL for Intermediate Language) to research how well a compiler stack behaves.

“C# emits .callvirt instructions, even if the method isn’t virtual. That forces a call site null check.” (Immo Landwerth on Twitter)
Posted by jpluimers on 2025/06/25
From a while back, which I initially missed because it was in the midst figuring out my ver increasing bowel problems leading up to all my cancer treatments, but still relevant:
[Wayback/Archive] Immo Landwerth @terrajobst@hachyderm.io on Twitter: “That’s why C# emits
.callvirtinstructions, even if the method isn’t virtual. That forces a call sitenullcheck.”
Except inside [Wayback/Archive] Extension Methods, referring to this will never return null.
Yes you can work around this using things like reflection, but the C# compiler will emit .callvirt for any method call which does an implicit null check by the caller which means you never have to check that in callees.
The above tweet quoted the first message of the [Wayback/Archive] Thread by @MStrehovsky on Thread Reader App on working around this .callvirt protection:

Naming things isn’t hard: if it contains a number, include the unit in the name (your timeout might not be in nanoseconds)
Posted by jpluimers on 2025/05/27
This case, it was C# accessing a SQL back-end, but the responses to the Tweet how so many more examples not even related to software development.
Remember that plane crashing because they overloaded while they thought the fuel load numbers were in Imperial pounds where in fact they were in metric kilograms?
That’s why naming things that contain numbers should contain the unit in their name!

Tweet: [Wayback/Archive] Nick Craver on Twitter: “Troubleshooting a hanging test suite and godDAMMIT. “In seconds”. Integer timeouts should be a felony offense punishable by an indeterminate amount of seconds/milliseconds/hours/fortnights/whatever the judge chooses.”
var csb = new SqlConnectionStringBuilder(TestConfig.Current. SQLServerConnectionString) { ConnectTimeout = 2000 }; int SqlConnectionStringBuilder.ConnectTimeout { get; set; } Gets or sets the length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. Returns: The value of the SqlConnectionStringBuilder, ConnectTimeout property, or 15 seconds if no value has been supplied.

Online .NET source code browsers for both .NET Framework and .NET Core
Posted by jpluimers on 2025/05/22
I used these .NET Source Browsers quite few times over the last decade, first for the .NET Framework and later for .NET Core (now called .NET, sometimes .NET Runtime) as well, but forgot to blog about them, so now that I discovered there is one for the Roslyn Compiler Platform as well, let’s list them all:
- [Wayback/Archive] .NET Source Browser
- [Wayback/Archive] .NET 4.8 Framework Reference Source
- [Wayback/Archive] Roslyn Compiler Platform Source Browser
- [Wayback/Archive] sourcebrowser Source Browser
It was introduced as [Wayback/Archive] referencesource-beta.microsoft.com by [Wayback/Archive] A new look for .NET Reference Source – .NET Blog which explains how to use it for browsing (on-line and off-line), Visual Studio integration, debugging, and more. In about a month however it got out of beta and became the primary as it functioned so well (you can verify this while browsing through the 2014 Wayback links).
All are powered by [Wayback/Archive] KirillOsenkov/SourceBrowser:
