As of June 30th 2022, my favorite software (besides from Simple DNS Plus) is:
Software Development tools
Software development components / libraries
Desktop software / Utilities
ClipClip - https://clipclip.com New in 2021
Clipboard manager / screen shots.
Notion - https://notion.so New in 2021
Notes, kanban boards, etc.
KeePass Password Safe - http://keepass.info
Great (free) program for storing passwords.
Storing the (encrypted) password database on DropBox makes it easy to sync between computers and my (Android) phone.
7-Zip - http://www.7-zip.org
Great for working with zip files and other compressed file archives.
I primarily use this because the built-in function for creating zip files in Windows 10 doesn't work with file names containing non-english characters.
TightVNC - https://www.tightvnc.com
For remote control of Windows "Home" edition computers. Also does file transfers.
CutePDF Professional - http://www.cutepdf.com
I mostly use it for scanning to PDF files, and for merging multiple PDF files into one.
TreeSize Free - https://www.jam-software.com/treesize_free
Figure out what is using all that hard disk space.
VirtualBox - https://www.virtualbox.org
Virtual machine software for the desktop.
Debut Professional - https://www.nchsoftware.com/capture
Screen recording / video capture. For making tutorials etc.
ZeroTier - https://www.zerotier.com
Virtual LAN in the cloud connecting all your remote locations and devices.
I have tried many different tools in all these categories over the years, and I can recommend all of the above over any competitors that I know of.
If you know of any better alternatives please do tell me in the comments below - always looking for better toys :-)
