Hi and welcome to BHW.
What kind of tools do you usually make to improve our life?
I can code zennoposter templates, php scripts and windows applications.
Examples
detectIPchanges.exe
it detects when your ip changes (mine changes every 24hours).
then it writes a text file with the current ip.
based on that you can trigger other events (like zennoposter templates)
statusCheck.exe
it reads text files from various folders and shows you when they were last updated.
Useful if you have alot of zennoposter templates and you want to know when the last time was when it successfully saved new data to text files.
spinner.exe
spin text from the command line
usernamegenerator.php
you can send a first and last name to the script and it will send you back a username.
it can create usernames that dont look like the usual ones (stevejackson1980).
So it randomly returns stevejackson80, sjackson1980, stevej1980.
It can also use fantasy names from a list and integrate them into the username, like
aeglosjackson, anglachelj80, AftershockJ1980.
I think this is useful if you want to register alot of accounts with a service like twitter and you don't want all usernames to look the same.
