[Wayback/Archive.is] capitaltg/thea: Certificate Checker
Certificate Checker provides an easy-to-use solution to check certificates, certificate chains, and TLS configurations. To run Certificate Checker for publicly-accessible web sites you can go to:
https://certchecker.app and enter in there a URL to check.
Users can easily run Certificate Checker in an internal network to validate or troubleshoot their TLS configuration. To run it on a local network you can run the Docker image as described below. You can also build the application and deploy it on an existing server.
It runs on [Wayback/Archive.is] Certificate Checker.
I used it to check various certificates and chains, including those for my GitHub Pages explained last week in Setting up a GitHub project so it is served over https as a custom subdomain.

There is a Harman Kardon Remote app on [Wayback/Archive.is] Android and [Wayback/Archive.is] iOS.
It can control Harman Kardon AVR and BDS devices, and the communication appears to be simple XML over HTTP according to [Wayback/Archive.is] H/K AVR 151 Remote Control API – Adam Parsons.
It got reverse engineered into two libraries, both based on string concatenating XML HTTP requests:
Note:
- the Harman Kardon Remote app only runs on my local IPv4 subnet (it won’t work routing from one IPv4 to another IPv4), hopefully the API works better
- the app does auto-detect (wich often fails) of on-line Harman Kardon AVR/BDS devices, I wonder how that is implemented
- there is this [Wayback] Harman Kardon AVR – Home Assistant plugin
- it works on some JBL devices too, as they are based on Harman Kardon internals: [Wayback] Harmon/Kardon AVR – Configuration – Home Assistant Community
I just tested it with a unit test and it work on my JBL AVR101 (same API as the Harman/Kardon)
- that the Harman Kardon remoting protocol is quite unstable (and even worse than the above Remote apps) that can only be solved by cold-rebooting your Harman Kardon device (observed this both on a BDS 277 and BDS 580), so be sure to have a remote controlled power outlet for that.
- You often have to cold-reboot these anyway because they stop listening to the IR-remote control as well or listen to HDMI commands (like ARC or CEC), so I already had such a switch in place.
- Same for Samsung TVs that over time will not wake up using CEC and require cold-rebooting
- various devices and firmware versions have different ideas of the
sleep command and eventually can perform a full shutdown, see the comments at [Wayback/Archive.is] Add list of known devices · KarimGeiger/HKAPI@6036d4f.
- the Harkan Kardon Remote protocol is totally different from the Harman Kardon Controller protocol used by the Harman Kardon Controller apps on [Wayback/Archive.is] Android and [Wayback/Archive.is] iOS.
- For people interested: the Harman Kardon Controller protocol is for the Harman Kardon Omni speakers and use a JSON/REST API, with:

I say to people: only use shell interactively, don’t write scripts. Never. Not one.
But Kris, they ask, why so radical?
Because of this:
is the literal English Google Translation of the German text
Ich sage den Leuten: benutzt Shell nur interaktiv, schreibt keine Scripte. Nie. Nicht eines.
Aber Kris, fragen sie, wieso so Radikal?
Deswegen:
then links to [Wayback/Archive] Jan Schaumann on Twitter: “TIL zgrep(1) is a shell script. BSD basically does “zcat | grep”, but GNU does “gzip -dc | sed”. How did I learn that? The fun way! CVE-2022-1271, arbitrary-file-write and code execution vulnerability in GNU zgrep / gzip. …”:

I’ve written about link rot quite a few times (it even has a category on my blog).
Preventing it is important, as it improves user experience.
For most users this is an unconscious thing when it works and becomes consciously annoying when it fails.
Some user groups are vocal enough to force you to fix link rot after the fact, causing brand reputation damage.
One good example was last year: [Wayback] Users condemn Microsoft for removing KB IDs from some bug documentation | Computerworld.
