Netbird has a command that will generate the appropriate auto-completions for you:

netbird completion fish > .config/fish/completions/netbird.fish

This will work for fish shell.

The MX Keys seems to want to pair using a passcode that needs to be typed using the keyboard followed by and Enter. Below are the steps I needed to take.

Launch bluetoohctl
# bluetoothctl

Turn on scanning
[bluetooth]# scan on

You will then see your keyboard
[NEW] Device 01:02:03:04:05:06 MX Keys

Select the device to pair
[bluetooth]# pair 01:02:03:04:05:06

You will see a pair code printed. Type that with they keyboard and hit enter.

Trust it
[bluetooth]# trust 01:02:03:04:05:06

Connect
[bluetooth]# connect 01:02:03:04:05:06

Since I recently changed from Chrome to Firefox, I’ve realized that Firefox does not make switching profiles as easy as Chrome does. You either need to

• Launch Firefox with the -P command line parameter
• Navigate to about:profiles and launch it from there

I wanted to have two separate taskbar icons that can help me differentiate between my profiles. In my case, Work and Personal.

I recently switched back over to Firefox again. As of yesterday I was using Firefox for Personal browsing and Chrome for work. Firefox doesn’t have a nice way to switch profiles on the fly and having to have a dedicated .desktop file with the “-p” option was a no go.

What I ended up figuring out was that in Linux Mint, I can modify the .desktop file that Firefox ships with to add an additional option to the right-click menu on the grouped window taskbar applet.

The default options that Firefox ships with are great but I want to add another for “Select a Profile”.

At the time of writing, Linux Mint stores it’s firefox.desktop (and a lot of other .desktop files) in the /usr/share/applications folder.

Let’s edit that file. You will first see a [Desktop Entry] on the first line. Scroll down until you see:

Actions=new-window;new-private-window;

And convert it to say:

Actions=new-window;new-private-window;new-profile;

Next, right below that, add a few new lines and the following text:

[Desktop Action new-profile]
Name=New Profile
Exec=firefox -P

Save the file.

The last step you need to do to make this live is to press Alt+F2 and then type r in the prompt and Enter. This will restart Cinnamon.

Now when you right-click the firefox image, you will see the following:

Today I had a customer report that on their Snom IP phones (specifically the D735 and D785 in my case), when they set the volume, after some time, it gets reset to max. Since they are a small office and have a ring-all ring group, it gets loud.

I suspected that the phone must be pulling it’s config periodically and that the provisioning template may be overriding what the user has set.

I logged into the web interface of one of the phones and manually set the volume to 1. I then manually provisioned the phone via PBXacT and it did indeed change the value to the max.

To stop this from happening, we will need to edit the base file of the template.

Go to Endpoint Manager > Basefile Edit and choose your template. Next choose the model of phone that you’d like to fix from the list on the left side.

Search the XML for vol_ringer and click on that line.

On the popup, edit the Perm field, which should be blank, and add a !

It should look like this:

The ! means that if the user has modified this setting, the phone should keep the modified option by the user. If the user has not modified this option, then the phone should take the provisioned value.

I have a web camera that has a built-in mic. It sometimes happens that my application will use that mic vs my headset mic because of reasons unknown.

I wanted to be able to disable the system from allowing the mic driver to be loaded so that it can never be used. To accomplish this I used the Linux udev rules to stop the kernel from loading the audio drivers for my device specifically.

Step 1: Find your device’s ID

$ lsusb | grep -i 'camera\|dualshock'
    Bus 001 Device 016: ID 0c45:636b Microdia USB 2.0 Camera
    Bus 001 Device 009: ID 054c:09cc Sony Corp. DualShock 4

Step 2: Create a udev rule

Below are the two file we will create.

/etc/udev/rules.d/01-webcam-mic.rules
/etc/udev/rules.d/02-dualshock-mic.rules

Create the following rule:

sudo printf "# Block Mic from Webcam\nSUBSYSTEM==\"usb\", DRIVER==\"snd-usb-audio\", ATTRS{idVendor}==\"0c45\", ATTRS{idProduct}==\"636b\", ATTR{authorized}=\"0\"" | sudo tee /etc/udev/rules.d/01-webcam-mic.rules

sudo printf "# Block Mic from Dual Shock 4\nSUBSYSTEM==\"usb\", DRIVER==\"snd-usb-audio\", ATTRS{idVendor}==\"054c\", ATTRS{idProduct}==\"09cc\", ATTR{authorized}=\"0\"" | sudo tee /etc/udev/rules.d/02-dualshock-mic.rules

Step 3: Reload the udev rules

$ sudo udevadm control --reload-rules

Step 4: Reboot

$ sudo reboot

I ran into an issue installing spotifyd on my Linux Mint PC and I wanted to document what was required to fix this.

The error:

error[E0658]: use of unstable library feature 'bool_to_option'
   --> src/config.rs:636:57

    = note: see issue #80967 <https://github.com/rust-lang/rust/issues/80967> for more information

To me this werror meant nothing. Apparently, according to a github issue, there is a bug in the Rust compiler. To fix this we need to uninstall rust from the Ubuntu/Lint repository and install it using a different command.

$> sudo apt remove rustc
$> curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Next you will need to exit out of your terminal emulator.

Finally you can follow the install instructions provided here.
