This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

• OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
• App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
• webos-vncserver frontend with autostart option
• Package hyperiond into Piccap directly
• Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
• Custom IR remote codes editor/updater/blaster

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

mwise

To use this hook:

• add the prepare-commit-msg file at .git/hooks/prepare-commit-msg and edit as needed
• make it executable: chmod +x .git/hooks/prepare-commit-msg
• disable fast-forward merges: git config branch.master.mergeoptions "--no-ff"
• that's it!

NOTE: after a failed merge from a forbidden branch, the working tree will still be in a MERGING state. To discard the local working copy state, run: git reset --merge

How to enable bind mount inside lxc container

When mount is returning:

STDERR: mount: block device /srv/database-data/postgres is write-protected, mounting read-only
mount: cannot mount block device /srv/database-data/postgres read-only

and dmesg shows:
