Make your own quadrille, graph, hex, etc paper! Uses the pgf/TikZ package for LaTeX, which should be part of any modern TeX installation.

To copy heroku database from one app to another and from local to heroku

To copy database from one heroku app to another -

heroku pg:backups capture [database_name]
heroku pg:backups restore $(heroku pg:backups public-url --app source_app) DATABASE_URL --app target_app

You can refer to https://devcenter.heroku.com/articles/heroku-postgres-backups for more information.

To copy database from local to heroku - Dump your local database in compressed format using the open source pg_dump tool: PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U myuser mydb > mydb.dump where myuser is your database username and mydb is the database name.

Github Two-Factor Authentication Failed For HTTPS

I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

Longer-lived feature branches can usually benefit from notes, so you can figure out more quickly where you were at in the process. TIL about branch descriptions, and made it easier to keep track of my various branches.
