How to serve a custom HTTPS domain on GitHub Pages with CloudFlare: *FREE*, secure and performant by default


CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

  1. Make sure you have registered a domain name.
  2. Sign up for CloudFlare and create an account for your domain.
  3. In your domain registrar's admin panel, point the nameservers to CloudFlare's (refer to this awesome list of links for instructions for various registrars).
  4. From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)
  5. If you

How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
    • the database is restored

Clojure is for Aristotelians

I was reading ["Clojure is for Type B Personalities"][2] and it sparked some thoughts I had about the intersection of western philosophy and programming.

One could say Mathematics is an extension of Epistemology. And all theory about computability are an extension of mathematics. I reckon how one thinks about computability and how one writes computable functions are a reflection of a person's natural epistemological tendencies. This is going to be just as unscientific as ["Clojure is for Type B Personalities"][2], but hopefully another
