This is a just crazy tech rant. Not even remotely a tech post or how to :D
So here’s how to do it.
Install Dropbox. Share a directory with a friend and create a text file inside it.
Now open the text file with a text editor. (I use Gedit).
Type in what you want to say.
ctrl+s to send :D
once your friend see the update s/he will (hopefully ;) ) type in and press ctrl+s.
you’ll get a notification from Dopbox about the file modification.
And also gedit will prompt that file is updated and will let you reload the file.
You reload and read the new entry and reply if you wish.
So there’s a very basic chat client :D.
Dropbox is an awesome piece of software. Runs on Linux, Mac and Windows. If you still didn’t try Dropbox, you should, now :).
PS: Click to get Dropbox with my friends referral and you both will get extra 250MB of space :) (Default free space of Dropbox is 2GB).
Update: Find more referral links in comments. And share your referral too :D (If you use Dropbox find your referral link here )
