Scripts to convert datasets from unruly forms to SQLite

The script json2sqlite.py reads files which have one JSON block per new line to be inserted in a database. This has become a rather common dataformat which is easy to incrementally parse. The arguments to the scripts are self explanatory.

Example execution: python json2sqlite.py --gzip aggressive_dedup.json.gz amazon.sqlite reviews

For a more upto date scripts, see: Networks-Leraning/datasets2sqlite.

As explained on Don't Be Scared of git rebase, git fetch+rebase is a better alternative to git pull; unfortunately it's not as concise.

git get

From now on, use git get instead of git pull, a custom command that does this:

# get data from remote
git fetch origin
# rebase the remote branch with the same name as local

# There are many greedy algorithms that could be used to pick a collection of sets that is close to as small as possible. Here are some that you will consider in this problem.
