To backup Nextcloud: there are four major components to deal with: folder nextcloud/config folder nextcloud/data folder nextcloud/theme folder nextcloud/config (added by me) (also possibly .htaccess) The database (can be MySQL/MariaDB, SQLite, or PostgreSQL) It's possible to manually back up folders, files, and the database. Have a look at the Nextcloud documentation to find out how to achieve that. It basically involves shutting down the application, letting it store its internal state on disk, backing up all files, and restarting Nextcloud. from: How to back up Nextcloud with Bareos – Nextcloud

To share a NextCloud image file, right-click on file to get link. You probably need to share file first. The image displays in other apps ok. The link will look something like this (it will differ with different NC providers): https://your_nextcloud.org/apps/files_sharing/publicpreview/TGgDBx69pBN6pTX?x=1522&y=626&a=true&file=filename.jpg&scalingup=0

“You may customize a Gallery album with a simple text file named gallery.cnf, which contains parameters structured using the Yaml markup language. You may have multiple gallery.cnf files; you need one in your own root Nextcloud folder (your Home folder) that defines global features, and then you may have individual per-album gallery.cnf files if you want to define different behaviors in different albums.” Docs source

A filedrop is available: “You may create your own special upload directories so that other people can upload files to you without having to log in to the server, and without being a Nextcloud user. They will not be allowed to see the contents of this directory, or to make any changes.' Docs source

Apparently, markdown syntax for images does not work when Note is viewed in a browser page (apparently IF the image is hosted external to the NC instance). Images do show when viewing the note in NextCloud. This is true for all NextCloud instances I've used. However, see this. Apparently, the reason that image displays ok on a webpage is that the image file is hosted on the nextcloud instance. This was confirmed on both nixnet and snopyta – images display ok when note is viewed as a web page IF the image file is hosted on the NC instance where the note is posted. CodiMD, HackMD, write.as, and writefreely notes do not have this limitation.

Provider Features Comparison:

Feature	Snopyta	CNow	OwnCube	Hostiso	Nixnet
MD Notes	Yes	Limited	Rich Text editor	Limited	Yes
Collabora	No	No	No	Yes	No
Storage	500 mb	5 gb	5 gb	3 gb	10 gb
Bookmarks	Yes	No	Yes	Yes	No
Gallery	Yes	Yes	Yes	Yes	Yes
Carnet	No	No	No	No	Yes
Performance	Fast	Fast	Medium	Slow	Slow

ocloud.de has an admin demo, so you can install apps that you want to learn about. The menus are in German though. Their free version gives 1gb space but Notes and the markdown editor are not included.

5 Ways to Undo Mistakes with Git: Discarding Some of Your Local Changes, Resetting a Specific File to a Previous State, Recovering a Lost Revision with the Reflog, Recovering a Deleted Branch, Moving a Commit to a Different Branch

Removing a git commit and force pushing to remove it from history; simonw TILs

How to push to a repo to maintain only one commit – useful if you would otherwise have a whole bunch of data-hogging commits that aren't necessary to keep. From simonw: The latest til.db file is now stored in https://github.com/simonw/til-db – every time I push a new copy of the file there I use git commit --amend to rewrite history followed by git push --force – so that repo only ever contains a single commit which is the commit that added the file.

How to change git master to main note the caveats in the thread

How to remove a pushed commit Committed and pushed incorrect file otd-tweets-by-mcnees (forgot the html extension). I could have dealt with the unpushed change but was in a rush and instead went ahead and committed/pushed corrected version otd-tweets-by-mcnees.html But later I wanted to remove that bad commit/push. Here's how I did it, using procedure from the above web page: git revert e98adc579131244c56913e0d5afbd5ba395bc6c8 Then git status said local repo was ahead of remote by 1 and that a push was needed. So I did the git push. The file then did not show up in the jrdmb/jrdmb github repo.
