Having cancer is not a fight or a battle, it is about having luck or misfortune

Posted by jpluimers on 2021/12/10

It has been a while after my last post about me having cancer. No, I am not giving up. But I am having the regular fear of the upcoming checks: did the metastases return, or do I have the luck to outlive some 30% of my peer group.

Post by @lookitup.baby (Ian Coldwater) — Bluesky on recharge being part of your work

Posted by jpluimers on 2026/06/11

I paid my therapist a zillion dollars to tell me this, so I’m passing it on to anyone else in MN who needs to hear it:

Think of taking time away to recharge not as not doing the work, but as doing quality control for the work. You’re not going to be able to show up to do it well if you’re depleted

The replies add a few other useful tips. Be sure to read the thread on BSKY.

A few days later, this Dutch post basically stated it in a different way:

Posted by jpluimers on 2026/06/10

[Wayback/Archive] This is useful for playing back in Cartrain CP7##BMW devices (currently CP700BMW, CP730BMW, CP740BMW) as these play back in the order in which directories and files have been created. which is related to Elektronik-Idee – CP740BMW – USB wireless MP3 Player (with Bluetooth and Audio/Video in support) and fully PowerShell 2.0 compatible:

Script to recursively copy directories in alphabetical order from source-base-directory to destination-base-directory
while adding an intermediate directory with a single uppercase letter in destination-base-directory for 
each set of directories under source-base-directory starting with that letter.

This is useful for playing back in Cartrain CP7##BMW devices (currently CP700BMW, CP730BMW, CP740BMW)
as these play back in the order in which directories and files have been created, as per:

  Unterordner sind hervorragend geeignet um Musik besser zu organisieren. Dateinamen und Unterverzeichnis sind in der Reihenfolge gleichgestellt. Die Wiedergabe der Titel in sämtlichen Unterordnern erfolgt der Reihe nach wie sie auf den USB Stick kopiert wurde
