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.

html – What can cause Chrome to give an net::ERR_FAILED on cached content against a server on localhost? – Stack Overflow
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.
ERR_FAILED

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.

linux – Get final URL after curl is redirected – Stack Overflow (plus some Twitter scraping tricks)
Posted by jpluimers on 2025/08/06
Sometimes I need [Wayback/Archive] Redirect Checker | Check your Statuscode 301 vs 302 on the command-line, so cURL to the rescue: [Wayback/Archive] linux – Get final URL after curl is redirected – Stack Overflow. The relevant portions of answers and comments further below.
TL;DR:
Since I prefer verbose command-line arguments (you can find them at the [Wayback/Archive] curl – How To Use on-line man page) especially in scripts this HTTP GET request is what works with Twitter:
% curl --location --silent --output /dev/null --write-out "%{url_effective}\n" https://twitter.com/anyuser/status/20https://x.com/anyuser/status/20
This failed (twitter dislikes HTTP HEAD requests):
% curl --head --location --silent --output /dev/null --write-out "%{url_effective}\n" https://twitter.com/anyuser/status/20https://twitter.com/anyuser/status/20
Notes
Given so many of my scripts now run on zsh, I added the new-line because of command line – Why does a cURL request return a percent sign (%) with every request in ZSH? – Stack Overflow. You can strip that bit.
Note that these do not perform client side redirects, so they do not return the ultimate originating URL https://x.com/jack/status/20 (which was the first ever Tweet on what was back then called twttr) as Twitter on the client-side overwrites window.location.href with the final URL. Similar behaviour for getting the Twitter user handle of a Twitter user ID, more on Twitter tricks below.
