There is a wide range of online tools for making certain tasks (development or not) easier, I've found a few that I thought I would share.
RegEx : regex101
This site has really helped me design a few of the more complicated regex's and is a great tool for getting to grips with how they work. Cheat sheet and window for putting the content you want to regex.
This site is great for giving me instant feedback on the markdown that I use for writing READMEs and wiki contents.
Great for working with mindmaps, this is good for brain storming, very easy to use and work with.
Some of you might have run into this software as a plugin for confluence, I found it years ago and have watched it really refine itself in drawing diagrams easily and directly.
Sending Files: Drop Send
I've hit issues with Email stripping attachments or with file size try out drop send.
Anyone got any other suggestions ?
