Make a language-specific setting like this (in your settings.json):
"[plaintext]": { "editor.quickSuggestions": { "other": false, "comments": false, "strings": false } }
This goes inside the bracket already in that file. Also to get to JSON mode you have to first click a little icon at the top right.
I used info from this guy's page: https://www.riksoft.it/wikiriks/linux/remove-foreign-fonts-from-debian-ubuntu
This command came in handy to spot any straddlers:
sudo dpkg -l fonts\*|grep ^ii|awk '{print $2}'It was 3x faster than sha256sum in my tests, but that includes a lot of just file I/O. So it must be comparatively a lot faster than that.
I decided to use a different Chromium profile for running some extensions, including translation extensions. Problem is I'm running under a Swedish locale, and me changing settings to translate into English in the extensions did not work; they were just ignored.
Finally in the custom desktop file I've made in order to launch a separate profile for Chromium, I put in a language environment variable on the execution line:
Exec=env LANGUAGE=en chromium --user-data-dir=/path/to/my/custom/profile/directory
A certain error message: "Freezing of tasks failed after 20.009 seconds", led me to this discussion on Nvidia.
Now installed it, will have to wait and see if it works.

Had some files that needed unpacking and was reaching for dtrx, but wasn't installed and also not in the Ubuntu repos. Found unp which seems to do more or less the same thing. Haven't tried it on zip files to unzip, tarballs, 7zip or other stuff yet though. Just .xz .

The final thing that made it work was realising that not all video formats are accepted by the free version. It will happily import them, but they can not be dragged on to the time line. Or if you succeed in creating a new timeline with them on, nothing is played as the play head traverses through them. This ffmpeg script seems to work to convert files:
ffmpeg -i infile.mp4 -vcodec mjpeg -q:v 2 -acodec pcm_s16be -q:a 0 -f mov outfile.movDescribed here: https://www.reddit.com/r/davinciresolve/comments/pxicvk/comment/ho2inmz/ , In fact there is listed a batch command:
mkdir transcoded; for i in *.mp4; do ffmpeg -i "$i" -vcodec mjpeg -q:v 2 -acodec pcm_s16be -q:a 0 -f mov "transcoded/${i%.*}.mov"; doneIt seems you need an external video card to run Resolve too, and the card must be active when running the installation script. Or you will get missing license key once you run the application with the graphics card.
Not that there comes any license key with the free version.
In order to switch to the card being always on I used the nvidia-settings app. I tried to do it also with some CLI command but it did not seem to stick.
Summary: No system wide setting has worked for me so far. You can open about:config in Firefox, search for "middle" and set to false as much as you can find there. In VS code you can search for "editor.selectionClipboard" and set it to false.
A dodgy mouse keeps middle clicking when the scroll wheel is used. This lead to a flurry of new tabs in Firefox and text all over the place in VS Code.
See: https://askubuntu.com/questions/1419274/middle-click-paste-disable for the VS Code setting.
Summary: Use a repository from the Linux Mint distribution. Promote chromium there and demote everything else from that Mint repository.Mint is like Ubuntu, but have decided to not go down the snap path.
The instructions are copied from here with very light editing such as a newer Mint (una → vera) https://askubuntu.com/questions/1386738/how-to-install-chromium-from-the-linux-mint-repositories-in-ubuntu :
Make a backup of the stuff from the snap chromium you want to keep, such as bookmarks
Uninstall snap's Chromium, and if you installed it via apt, remember to also uninstall chromium-browser there or you will get a conflict that prevents Mint's Chromium from being installed
Create an apt source file for the Mint repository:
echo "deb http://packages.linuxmint.com vera upstream" | sudo tee /etc/apt/sources.list.d/mint-vera.listTo prevent NO_PUBKEY you have to add the GPG key by this:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com A1715D88E1DF1F24 40976EAF437D05B5 3B4FE6ACC0B21F32 A6616109451BBBF2Then update package lists by apt: sudo apt update
Prevent installation of other packages by pin-file:
cat <<EOF | sudo tee /etc/apt/preferences.d/pin-chromium
Package: *
Pin: release o=linuxmint
Pin-Priority: -1
Package: chromium
Pin: release o=linuxmint
Pin-Priority: 1000
EOFInstall chromium:
sudo apt install chromiumSome browser extensions cannot work with snap versions of Firefox and Chromium and snap is what Ubuntu offers nowadays. The snap people are working on making extensions that need to communicate outside the sandbox to work in both in Firefox and Chromium, and it seems they have a solution you can use for Firefox, if you snap install firefox-beta. Untested by me. Once they get the irons wrinkled out as one says, they will make this work for Firefox normal and for Chromium.
See: https://www.omgubuntu.co.uk/2022/07/ubuntu-devs-fix-another-frustrating-firefox-snap-flaw
You could conceivable get some glue to work inside the snap for e.g. Chromium, similar to this guide for Firefox and Flatpak:
In that case you'd put a proxy binary inside the snap and some JSON for the browser.
If Ubuntu Linux on the desktop was a car
Today when I went out to the garage, two wheels were missing from the car. After some searching it turned out to be a conflict between the mechanic and the guy who changes the wheels to winter tyres. I pinned the mechanic to the ground and praised the tyre guy a 1000 times, and the wheels snapped on again.
A security update (UPS update) had disabled old unsafe driving modes such as driving in reverse. It was just a question of going under the engine hood to file off two serial numbers and I could after a restart, back out of the garage.
The car keeps middle-honking when I turn the steering wheel but there is no workaround as of right now.
In a terminal, just issue:

Sound disappeared in Firefox sometimes and did not come back, while playing YouTube videos. Only recourse seemed to be to restart the computer! I got it back by installing a new sound system called pipewire, see instructions here: https://ubuntuhandbook.org/index.php/2022/04/pipewire-replace-pulseaudio-ubuntu-2204/
Seems to be a problem for a certain Intel chipset?

encfs is an old deprecated way of encrypting a volume. It may have problems working on newer Linuxes, unless you allow OpenSSL to use old stuff. More info here: https://askubuntu.com/questions/1405656/encfs-segfault-in-version-22-04
It's better to replace encfs with something better, such as the pretty much standard luks/luks2.
Well, the answer from me is that I don't know but some seem more trustworthy than others. apkmirror has a known team behind while e.g. apkpure does not. According to this comparison, apkpure has had malware included, and no one knows who's behind the site: https://www.slant.co/versus/7899/22173/~apkmirror_vs_apkpure
So if choosing between these two, https://apkmirror.com seems the better option. If it's good enough, no idea.
Preliminary notes. I wasn't exactly sure what I was doing here. Maybe it was already mounted and that was the problem. Anyway, files saved.
A USB boot disk with luks2 and LVM refused to boot. Needed to save the files from it.
I connected it to another computer.
Used this to figure out its /dev/sd(letter)(number):
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABELIt was /dev/sdc6. Opened it into a logical volume name that I made up, "my_encrypted_volume":
sudo cryptsetup luksOpen /dev/sdc6 my_encrypted_volumeMade a local mount point in the home directory
mkdir -p mnt/rescueMounted it there:
sudo mount /dev/mapper/my_encrypted_volume mnt/rescueAnd that did not work for me, it may work for you. I got an error message about:
mount: unknown filesystem type 'LVM2_member'I figured out its LVM(?) name by issuing:
sudo pvscanThen took that name, e.g.: "root-vg" and issued:
sudo vgchange -a n root-vg
sudo vgchange -a y root-vg…to make Linux mark it as inactive, then active again. Got this info from this page:
https://svennd.be/mount-unknown-filesystem-type-lvm2_member/
And then it could be mounted and then accessed under $HOME/mnt/rescue. Copied files off of it with:
rsync -rh --progress mnt/rescue/path/to/files /media/username/mybackudisk/backups/The lsblk dance I got from https://askubuntu.com/questions/182446/how-do-i-view-all-available-hdds-partitions .
Simple 3 point lighting rules for a talking head. I took these from a video, published here as notes for myself only. Don't take lighting advice from me without double checking!
First light, right or left (maybe camera's left best?). 45 degree angle, a bit above the subject if you want Rembrandt's triangle. No sharp light, since it casts sharp shadows
Second light, same setup but opposite side. Less light.
Third light, directly opposite first light but higher up, out of shot.
Background should be darker on the more lit side of the face. Background overall in between the brightness of the left and right side of the face of the subject.
Background can have complement colours, each side.
To make a systemd Linux check its boot disk on startup, you provide a special boot parameter, fsck.mode=force. So in /etc/grub something like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet fsck.mode=force"And then remember to update grub.

Updated 2022-11-26: What seems to work for me now on Ubuntu 22.10 is to install a Firefox extension which then smoothly and a bit worryingly integrates with gnome on my desktop.
The extension can then be installed from here: https://extensions.gnome.org/extension/1160/dash-to-panel/
Old text:
You have to download dash-to-panel. This can be done by installing gnome extensions manager from the standard repos. Then choose "Browse" and type a search string to find dash-to-panel. Nota bene that gnome extensions manager only presents the first twelve or so search results, so you've got to do a reasonably precise search.
Once installed, you can configure dash-to-panel either from gnome extensions manager or from gnome extensions app.
gnome extensions manager:
gnome extensions app (in Swedish)
In either one go to dash-to-panel's settings and under "Behavior" select "Ungroup programs" (sorry about the Swedish):
And your dock, if it's vertical will start to look like this:
You can use heretext. The syntax seems to be:
commmand <<< $"file contents"
Tested by me. Or use single quotes. See: https://stackoverflow.com/questions/5852643/piping-in-on-the-command-line-simulating-a-file
