I had one of the LeapMotion input devices back around when they launched, and really did try to use it in earnest - using a whole bunch of shortcuts and AutoHotkey hacks to navigate the OS with it. There were even experimental programs people wrote to input text with it, using something similar to chorded keyboards.
It didn't really work out though. Long story short: my arms got tired. Turns out that it's a kinda fundamental problem with how they had designed the interface - hovering your hands above something for extended periods of time is simply just tiring and uncomfortable.
Syncthing. Been using this combination for a few months now and seems to work fine between an Android phone and a few Windows + Linux machines.
I had previously been hosting TiddlyWiki from my phone, but offline editing + opportunistic syncing when on WiFi seems to fit a personal wiki better for me.
Highly specific to Dell XPS laptops, but I used to have a similar issue to this. Eventually realised that the display wasn't actually turning off sometimes when I closed the lid. After much mucking around, it eventually turned out that in some of these laptops the magnet in the lid that triggers the "lid closed" action can become physically unstuck, and move around in the display housing (on my XPS 9350 this is in the bottom right corner of the display). Using an external magnet to jiggle it around both allowed testing to trigger the sensor and confirm the issue, and also to move it back to its proper location. Seems to work properly again now.
This sounds like a great idea, and I'm sure there's people that would be willing to help (me included). Is there somewhere organized already for people to discuss the development, or where to contribute (Gitter, Discord, IRC, etc.)? I couldn't find anything mentioned in the GitHub pages.
I've been using SyncThing for years with my KeePassXC database without issues (including Android for use with Keepass2Android).
On the odd occasion it's been modified on two devices without a sync and SyncThing produces a sync-conflict file, a simple "Merge from database..." within KeePassXC happily pulls in the newer data from both databases to merge them again.
I use the Staggered File Versioning feature on at least one device + a separate backup mechanism to satisfy my paranoia about losing the database.
