To create a shortcut of an appimage into your Applications menu (Linux Mint XFCE) but probably works with Cinammon too
On your Desktop right click and choose Create Launcher
Name: Krita 5.2.0
Command: browse to your directory of appimages and choose Krita.appimage
right click on Krita 5_2_0.desktop file you just created and open with Text Editor and add
If you have many appimages it's best just to drag your appimages folder to sidebar in the file manager and open them by double clicking them. That's what I do.

Mainting aspect ratios. Just like in some photo editing programs when you resize an image by dragging a photo at its corner you need to hold SHIFT to lock its aspect ratio so the same concept for upscaling or descaling videos you wish to re-encode.
In ffmpeg using
-vf scale=-2:720
-2 preserves aspect ratio and 720 says downscale to 720p. In the screenshot it’s a 1080p (970p) video and no need to use this aspect ratio calculator to figure out your width would need to be 1475.

Video and audio conferencing. Most know Zoom. Telegram in July 2021 rolled out up to 30 participants. Easily can record the video stream and or just audio and after sends them to your Saved messages. I’d still re-encode them to reduce the file size.
Jistsi I’ve used a little bit but no longer a fan. Jami I am a fan of and can do video conferencing too and around 30 too. Jami is totally decentralized. In fact I became aware of it when investigating off the grid communication. Supposedly you can have a Wi-Fi network setup WITHOUT internet access (like on a ship) and two phones can communicate video / audio or text / video / audio messaging. Send files even.
December 23, 2021 they’ve finally released the swarm feature. I need to get more people on Jami because between Telegram and Jami those seem to have the best privacy options. Once Jami gets group chat guessing mid 2022 it should be really good. Right now just 1 to 1 chat for swarm.

Jami swarm feature just means conversation history you have with someone will show up on your eyephone, android, Linux, windoze or BigMac. So what? All social media apps do this. Yes but Jami doesn’t have central servers so it was a huge technical feat to implement.

Linux Mint XFCE 20.3 is out. Download the the ISO with torrent using Transmission. On Windows or Linux use QBitTorrent.
If you never have used torrent before then be sure to set your Upload speed to something low and Stop seeding ratio (sharing) ratio at like .25 (1/4). So if you download 2GB you share 500MB.
I plan to just upgrade Linux Mint 20.2 to 20.3 following these instructions

freac (open source free) re-encode 256 and 128kbps mp3s (just talking / no music) to 32kbps. Can set in encoding options to automatically delete source files and to output to same folder as source. Also use this to convert entire music collection mp3 320kbps files —> opus 96kbps files.
Apps you wish to startup at boot. Go to Settings | Session and Startup

VLC I use the command

Combine a subtitle SRT file and hard burn-in video. Usually for movies, tv shows you don't want to do this as you just use external SRT files. However, if your audience is say on telegram and they aren't gonna download the mp4 or mkv along with the SRT then this is a solution.
Here's my videomass command I used to encode an mp4. Notice double quotes " enclose the single quotes '.

I recommend set it to once a week and just keep one snapshot if something goes wrong you can restore a snapshot. In the screenshot it shows 20.2 which I could revert back to in case 20.3 upgrade didn't go smooth. No need to though as it went without a hitch as expected.
Only optimizing a PDF for file size and no need to OCR it so from 20.3MiB —> 10.7MiB.
-s is same as —skip-text (skips text if already OCR'd)
-O (that's a letter O not a 0 zero) - - optimize and 3 does aggressive lossy optimizations (including lossy JBIG2)
- - skip-big tells it to skip any page over 0.1 Megapixels (which would be every page)
INFO - Start processing 4 pages concurrently

The LibreOffice suite includes several
tools, including:
Writer - the word processor (MS Word)
Calc - the spreadsheet (MS Excel)
Impress - the presentation tool (MS Powerpoint)
Draw - for diagrams, flowcharts, leaflets, etc. (MS Visio)
Base - for databases (MS Access)
Math - to create formulas
If not using Base for a quicker start up time go to Tools | Options | Advanced and uncheck Use a Java runtime environment
When saving an odt choose Hybrid if you wish to embed the odt file within the PDF making it editable later with LibreOffice Writer although at a cost of file size.

Exifcleaner cleans out exif data in images and metadata from videos and PDFs. It can be installed by downloaded a .deb file or appimage. I do like it better than Metadatacleaner even though that one has gone down from 600MB to 68MB recently. It has darkmode and you can drag files onto it compared to the other one you couldn't.
Qprompt.app is a free teleprompter. Works well and can mirror on two screens so one can control and other can display to speaker. Download appimage.
