HaaS

I am not able to get on with my one-blog-post-per-week routine. I have a set of blog posts in various stages of writing, some just being a title to some being almost completed pieces. And I usually upload them on Fridays.

If I missed the Friday mood and deadline, I wait till next Friday to post. But now the gap between posts are increasing. So I thought I will do a small emergency post.

Today is Saturday and on Saturdays the road traffic is a bit lesser than week days. The peak congestion hours in Hyderabad are 10 am - 12 noon and 6:30 p.m. to around 9 p.m. And during these peak hours, a travel that take 30 - 40 minutes ends up taking 1 - 1.5 hours.
