How to link to headings in GitHub issues and pull requests

If you have an issue comment / PR description on GitHub, it doesn't automatically get anchors / IDs that you could link to:

What I like to do is to add a visible # character like this:

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.

The Zen of Cypher

• Write functions() in lower case, KEYWORDS in upper.
• START each keyword clause
  ON a new line.
• Use either camelCase or snake_case for node identifiers but be consistent.
• Relationship type names should use UPPER_CASE_AND_UNDERSCORES.
• Label names should use CamelCaseWithInitialCaps.
• MATCH (clauses)-->(should)-->(always)-->(use)-->(parentheses)-->(around)-->(nodes)
• Backticks `cân éscape odd-ch@racter$ & keyw0rd$` but should be a code smell.
