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 »

In case I need a small 5-port managed switch that can do port-mirroring: GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support
Posted by jpluimers on 2025/08/13
[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.
This is a newer and cheaper hardware revision than the:
- GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
- GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold
Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:
- there are different revisions of the GS105E with the above drawbacks
- there is GS305E

Comment Only What the Code Cannot Say | by Kevlin Henney | Medium
Posted by jpluimers on 2025/08/13
Often after having taught a topic for decades, somebody rephrases it in a beautiful concise way:
[Wayback Comment Only What the Code Cannot Say | by Kevlin Henney | Medium
Kevlin has the same two quotes I have included teaching software quality for a long time:
In The Elements of Programming Style, Kernighan and Plauger note thatA comment is of zero (or negative) value if it is wrong.Instead of writing apologies and apologia, follow Kernighan and Plauger’s advice from the 1970s:Don’t comment bad code — rewrite it.

Hopefully by now the Chocolatey .nuspec extensions and limitations are documented in a more central way
Posted by jpluimers on 2025/08/08
Chocolatey extends the NuGet file format .nuspec based XML files as base for their packages with at the time of writing very sparse and limited documentation in what it extends, why it does that and what extra limitations it imposes on the fields used inside .nuspec files.
Hopefully by now that has improved, so this post is a reminder to myself to check that out eventually.
At the time of writing, the NuGet .nuspec documentation was at [Wayback/Archive] .nuspec File Reference for NuGet | Microsoft Learn and the file format at [Wayback/Archive] NuGet.Client/nuspec.xsd at dev · NuGet/NuGet.Client. Most fields are defined as primitive data types xs:boolean, xs:string and xs:anyURI (of the 19 available primitive XML SChema (W3C) types). Some composite data types are are composed from them using local and global complexType, most using xs:all, xs:attribute or single-type unbounded xs:sequence (which all imply no particular order).
Since an XML Schema allows to both use restriction and extension on data types (the eXtensible in XML!), making them more strict is a relatively straight-forward operation and has the benefit of having these in a central place.
In the past for more than 5 years [Wayback/Archive] Is there a specification for the package format? · Issue #379 · chocolatey/choco was just pointing to the NuGet .nuspec format, but after a request to re-open new comments were made pointing to a current issue (basically a stub, but still) and a Chocolatey nuspec.xsd file, yay!
Still it was a quest to figure out the additional rules they have added, especially since the documentation was sparse and sloppy.

Posted by jpluimers on 2025/08/07
On my research list [Wayback/Archive] html – What can cause Chrome to give an net::ERR_FAILED on cached content against a server on localhost? – Stack Overflow
The reason what that back then this would fail (but worked in Firefox and Safari, and because I was in a hurry I didn’t research further): [Wayback/Archive] https://www.office.com/
This site can’t be reached
The webpage at https://www.office.com/ might be temporarily down or it may have moved permanently to a new web address.

Looking for an alternative to the (now dead) ZXing Barcode Scanner – Apps on Google Play
Posted by jpluimers on 2025/08/07
Edit 20250807: (thanks [Wayback/Archive] twm/dummzeuch!) at [Wayback/Archive] dummzeuch: “@wiert yeah, I found out about…” – Mastodon
@wiert yeah, I found out about this a few weeks ago, when I wanted to install it on my new phone.
I switched to this one:https://gitlab.com/Atharok/BarcodeScanner
But I haven’t used it enough to be able to make a final evaluation.
So I will try [Wayback/Archive] Atharok / Barcode Scanner · GitLab with the install from the Android App-store [Wayback/Archive] Scanner: QR Code and Products – Apps on Google Play.
