[CAP] min and max functions
Since there is nothing in the official CAP documentation about min and max functions, I figured out the following syntax:
const result1 = await cds.run(`SELECT *, MAX(seqNr) FROM ${myTable} LIMIT 1`) //returns array
const result2 = await SELECT.one.from(myTable, [`MAX(seqNr)`]).columns('*') //returns object
const result3 = await SELECT.one.from(myTable).columns('MAX(seqNr)') //returns object containing only the max counter value
[Proxmox] Upgrade 7.4 to 8.0 – Failed to run lxc.hook.pre-start for container
After updating my Proxmox Server to PVE8.0, suddenly two lxc containers did not start anymore.
root@pve:~# pct start 192
run_buffer: 322 Script exited with status 2
lxc_init: 844 Failed to run lxc.hook.pre-start for container "192"
__lxc_start: 2027 Failed to initialize container "192"
startup for container '192' failed
I tried to view the error.log but couldn’t find any helpful information.
lxc-start -lDEBUG -o error.log -F -n 192
When googling, I stumbled across this reddit post. Although the issue was a bit different, I tried the recommended steps. The first command, directly led me to the right direction…
root@pve:~# pct mount 192
mounting container failed
directory '/mnt/nfs/data/folder' does not exist
For whatever reason, after restarting proxmox it did not mount the nfs shares properly on the host. And of course, after this hint, I noticed that both containers were trying to mount some of these folders, which were actually nfs shares from my NAS. A simple mount -a on the host fixed it immediately. Besides of this little problem, everything went well with the proxmox upgrade!
[Firefox] uBlock – Cloud Storage
Since version 1.1.0.0. uBlock can sync its settings via the brower build-in sync ability, in case of Firefox it’s called Firefox Sync.

The export process must be triggered manually in each uBlock tab.

[Home Assistant] Ikea Traefdri Reset Script / Pairing mode
Handy script, to put Ikea Bulbs into pairing mode by using a Zigbee Switch: https://community.home-assistant.io/t/handy-script-to-reset-ikea-tradfri-bulb/435622
Just go to Settings -> Automations -> Scripts and paste the following YAML script:
alias: Reset IKEA bulb with Switch
sequence:
- repeat:
count: "5"
sequence:
- service: switch.turn_off
data: {}
target:
entity_id: "{{ smart_plug }}"
- delay:
hours: 0
minutes: 0
seconds: 0
milliseconds: 900
- service: switch.turn_on
data: {}
target:
entity_id: "{{ smart_plug }}"
- delay:
hours: 0
minutes: 0
seconds: 0
milliseconds: 500
variables:
smart_plug: switch.REPLACE_SWITCH_NAME
mode: single
Now just insert your light bulb with a light socket into the plug and run the script.
To use the script with other bulbs, just adjust the counter and seconds to your needs, e.g. like here for Ledvance bulbs:
alias: Reset Ledvance Gardenpole with Switch
sequence:
- repeat:
count: "5"
sequence:
- service: switch.turn_off
data: {}
target:
entity_id: "{{ smart_plug }}"
- delay:
hours: 0
minutes: 0
seconds: 5
milliseconds: 0
- service: switch.turn_on
data: {}
target:
entity_id: "{{ smart_plug }}"
- delay:
hours: 0
minutes: 0
seconds: 5
milliseconds: 0
variables:
smart_plug: switch.REPLACE_SWITCH_NAME
mode: single
