GM Yasser Seriawan coined the term "Howler" to refect a very bad move made in chess. In chess the usual term used for a bad move is a blunder. So a Howler is a BAD blunder.
I made the biggest howler when I lost all my website content because I missed payments for the website a few months back. That's years of content from the Catur portal, chess calendar, pictures and various other blogs lost!
What's worse is that all that could have been avoided if I was not stingy and save on the optional 1$ per month payment for automantic backup.
Well, I have set up from scratch all my websites on Digital Ocean based on Singapore server and this time I will not skim on that $1/month.
