Veel Streamdeck tips in het topic “Mountain brengt DisplayPad- en MacroPad-toetsenbordjes uit voor content creators”

Posted by jpluimers on 2024/04/29

Het grappige van sommige Tweakers.net artikelen is dat er dan ineens veel tips over een concurrerend product in staat (omdat de laatste over het algemeen op bepaalde vlakke beter is).

Zo ook met diverse handige Stream Deck (van Elgato) tips in commentaar onder het artikel [Wayback/Archive] Mountain brengt DisplayPad- en MacroPad-toetsenbordjes uit voor content creators – Computer – Nieuws – Tweakers.

When Ctrl-Alt-Del fails on Linux: Fix a Frozen System with the Magic SysRq Keys (via FOSSwire)

Posted by jpluimers on 2024/04/26

Ctrl-Alt-Del will not safely reboot all systems under all circumstances.

If you run Linux, your keyboard has a magic RysRq key (sometimes not marked, but its the same key as the Print-Scrn key) and the Linux kernel is still running not all is lost.

Due to link rot, the archived links are the most recent that have all the comments for [Wayback/Archive] Fix a Frozen System with the Magic SysRq Keys | FOSSwire which amend

You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn’t have installed that bad driver, but you did it anyway.
So you reach for the power button.
Stop.
Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job.
  1. Hold down the Alt and SysRq (Print Screen) keys.
  2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
  3. Watch your computer reboot magically.

This 2007 comment makes it easier to remember: REISUB is the reverse of BUSIER:

R E I S U B – is just the word busier in reverse.

Robust DYMO label writers with USB interface for printing shrink tube: DYMO Rhino 6000 and 5200 (via Bradán Lane on Twitter)

[Wayback/Archive] Bradán Lane on X: “@jpluimers @jilles_com I have a DYMO Rhino 6000. “New” they are pricy but the 6000 and 5200 are often on eBay at really good prices. I have used the USB interface on it for automation and to upload custom graphics.”

This was in a response thread started by [Wayback/Archive] Jilles.com which you will find further below.

Karoly Negyesi on Twitter: “Apparently some/many/most powered USB C hubs with Ethernet are causing serious problems when not connected to a computer. This is such an amazing interaction of various standards.”

Posted by jpluimers on 2024/04/05

TL;DR: for the foreseeable future, avoid USB C hubs with built-in Ethernet as they will bring down your local LAN when no PC is connected to the hub.

VoIP: passing on a phone number from one Fritz!Box to another Fritz!Box

Posted by jpluimers on 2024/03/11

Most Fritz!Box VoIP configurations have a phone number configured to only work on telephony devices (i.e. handsets) on the same Fritz!Box.

But it is possible to define a telephony device that itself is another VoIP end-point.

This way you can hook a second (or more) Fritz!Box up to the phone number(s) of the first Fritz!Box.

I am using this for two reasons:

Below is how to get this going, assuming the first Fritz!Box is a 7490 running firmware 7.29 and the second is a a 7360 with firmware 6.33 (other versions and firmware versions vary slightly).

But first the related post: Many links about free modem/router choice and their configurations for the Dutch KPN internet/VoIP provider where I figured out that just using a 7360 won’t cut it any more.

thuddevort on Twitter: “You can disable the extra confirmation under System > FRITZ!Box Users > Additional Confirmation”

Posted by jpluimers on 2024/02/16

My ISP did auto-update the Fritz!Box, but did not send release-notes, so I was not aware this feature had been added eons ago:

[Wayback/Archive] thuddevort on Twitter: “@jpluimers @wijnands @b0rk @xs4all You can disable the extra confirmation under System > FRITZ!Box Users > Additional Confirmation”.

I know a second factor is better for security, but doing that on both sites at the same time when setting up LAN2LAN VPN is tough (Fritz!Box names this either “LAN-LAN coupling” or “VPN Connections between the FRITZ!Box and Other Networks”.

A better feature at the same configuration page is instead of disabling, enabling to confirm using apps like Google Authenticator and Authy:

Reminder that the Fritz!Box IKE error 0x1C is still barely documented: crucial places like the built-in help page point to non-existing URLs

Posted by jpluimers on 2024/02/12

A while ago, I had to redo all of the existing Fritz!Box LAN2LAN VPN connections.

It was a pain for many reasons, reminding me of the pain

This is why it was so painful:
