Map-side join example - Java code for joining two datasets - one large (tsv format), and one with lookup data (text), made available through DistributedCache
This gist demonstrates how to do a map-side join, loading one small dataset from DistributedCache into a HashMap
in memory, and joining with a larger dataset.
Includes:
---------
1. Input data and script download
2. Dataset structure review
3. Expected results
4. Mapper code
5. Driver code

petehunt / React sortable
Created December 9, 2013 22:30
Here's an example of React + jQuery UI sortable. The key thing to note is that we have the render() method do absolutely nothing and use componentDidUpdate() + React.renderComponent() to proxy updates through to the children. This lets us manage the DOM manually but still be able to use all the React goodies you know and love.

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

  • create tasks T{NNNN} asign them
  • create a branch with name like "T{NNNN}-boo-hoo"
  • git checkout -b T1234-boo-foo
  • commit changes on that branch until it gets ready to be reviewed
  • git commit -am 'first'
  • git commit -am 'now it works'
  • check if it's lint free (NOTE: it runs lint against only modified files)
  • arc lint
  • push a review request to the server. This will create a diff with id D{NNNN}
  • arc diff
