Why should text files end with a newline?

Why should text files end with a newline?

Reasons:

  • UNIX standard
  • If the last line in a file doesn't end with a newline then addition of next line affects two lines instead of one. This also pollutes diff on multiple files, so reader may wonder what has changed in a line whereas no significant change has occured.

Multiple newlines at the file end are also redundant as well as spaces at the end of line.

Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

PostgreSQL index naming convention to remember

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

  • pkey for a Primary Key constraint;
  • key for a Unique constraint;
  • excl for an Exclusion constraint;
  • idx for any other kind of index;
