Posted by jpluimers on 2017/03/06
In case you manually want to configure or have a web-server that’s not supported by certbot for letsencrypt (yet): Generate Mozilla Security Recommended Web Server Configuration Files.
At the time of writing, these were supported by the generator (* were not supported by certbot for letsencrypt yet):

Getting the IP addresses of gmail MX servers – via Super User – dig isn’t enough
Posted by jpluimers on 2017/03/06
I needed the current IP-addresses of the gmail MX server (don’t ask the details; but it has to do with the brain-dead TP-LINK ER5120 configuration possibilities).
This is the command I finally used:
dig @8.8.8.8 +short MX gmail.com | sed "s/^[0-9]* //g" | sed "s/.$//" | xargs -I {} dig @8.8.8.8 +short {} | uniq | sort
Basically it’s a three stage sequence which had to work on OS X as well as Linux using a bash shell:
- Use the Google DNS servers (either 8.8.8.8 or 8.8.4.4)
- Get the FQDNs of MX records of gmail.com which are the mail servers for GMail.
- Translate these in IPv4 addresses
- Filter into a distinct list (just in case entries are duplicate: they aren’t yet, but might be)
The basics of the above are about using dig to get short (or terse) answers with as little (but still to the point) information as possible.

Factory restoring a 3rd generation Apple TV was more cumbersome, but I learned about BlueTooth keyboard sharing from my Mac
Posted by jpluimers on 2017/03/03
Apple TV needs iTunes
A while ago, my model A1469 3rd generation Apple TV had a slowly blinking white light but nothing displayed over HDMI any more, so I searched for Apple TV slow blinking white and
Reading Restoring your Apple TV (when its white light is flashing) | Comics and gadgets, I opted for the first option: a soft-restart of the Apple TV. To do that you have to press menu+down on the Apple Remote at the same time for 5+ seconds, then wait for the Apple TV to restart. That initially did show an image over HDMI which later disappeared. I didn’t get the image at first as I thought it was looking for iTunes media over USB (like from an iPhone or iPad), so I waited for a time-out to occur.
After a while that image disappeared and the Apple TV white LED started rapidly flashing. Not good.
Later I found the image was portraying a USB cable not having a connection to an iTunes logo and some dark grey text on a black background pointing to support.apple.com/appletv/restore.
I didn’t see that at first as the room was a bit brightly lit since we had a lot of sun that day so this non-descriptive image with grey on black UX worked really well.
Conclusion: I had to restore the Apple TV which I thought would be straight-forward as it had been connected to my iCloud account.

230 V safety on the work bench – Put your power supply in an old tablet container…
Posted by jpluimers on 2017/02/28
Great tip from Nelis Willers:
230 V safety on the work bench.Put your power supply in an old tablet container. The high voltage is safely encapsulated and will not accidentally touch something. Of course don’t do this for a kW supply, only where low heat is generated, otherwise you might set a fire!
