This does not include any private repos such as my corporate work eg. where most of my Pull Requests and many of my commits went.

This only includes my public open source repos:

Core Public Repos

GitHub's limit of 6 pinned repos is far too low - these are what I consider my core open source public repos:

How the Hell, Bro

I get asked this a lot.

How the hell did this crazy guy write all these thousands of programs and scripts...

Well... honestly, unless I have something specific to do, this is me 👉

... often even at midnight.

I am simply not a man of moderation. The few things I care about in life I do a lot.

Even crazier, the first decade of my career I released almost nothing because GitHub didn't exist when I started, so I have even more code stuck in private repos that I maintained and migrated over years in Subversion, then Mercurial, then Git, but have no time to go back to QA and release.

codecat

Writing the above I suddenly got curious enough to quickly rustle up a new Golang program to generate this graph of my public repo commit times to see when I'm most active.

Generated by HariSekhon/GitHub-Graph-Commit-Times:

GitHub Times Graph

The TL;DR takeaway from the above graph is don't bother me in the mornings, I take a while to warm up 😉.

I also dip a bit around midday and 9pm as I need to eat once in a while... and sleep a few hours in the very early AM.

I just found out why my DevOps-Bash-tools repo stars went vertical in the graph above. GitHub themselves showed it at the top of their Trending repos page:
