These are hexdumps of the tarball added in isaacs/node-tar#187

• gnu-tar from gtar -cf ...
• gnu-posix-tar from gtar --posix -cf ...
• bsd-tar from bsdtar -cf ...

edit: I've added additional line breaks at the 512 byte boundaries to make it easier to see the tar framing.

# Print tab-separated details for the given file based on the package that owns it
# Usage:
#  awk -v file=/path/to/some/file -f find.awk /lib/apk/db/installed

    # multi-line records, go!
    RS=""
    # our input fields are lines, but our output is tab-delimited

// original Promise-only version. I try to write my functions to be pure
// when appropriate so that they are composable in to promise chains like
// this
function findOrCreateUser(id /* :string */, user /* :User */) /* :Promise<User> */ {
  return db.users
    .hsetnx(id, 'created_at', user.created_at.toJSON())
    .then(function(isNew) {
      if (isNew) {
        logger.info({user: user}, 'New user');
        return db.users.hmset(id, serializeUser(user))

Idea:

A simple shorthand for foo.bar.bind(foo, ...) to make it nicer to work with partial function application.

// shorthand
function sillyClone(input) {
  var acc = [];
  input.forEach(acc.push&());
  return acc;

https.get('https://nodejs.org/dist/index.json', onResponse);

function onResponse(res) {
  // monkey patch using our Symbol as a key

  // event emitters invoke handlers using emitter as 'this'
  res.on('data', accumulate);
