I bet it's no more than ten minutes on a busy day, between 6:30 and 7:30, between coffee and thinking about work. Meditation is hard when you have something to do and must do it. Meditation is an Eastern thing and it doesn't play well with the Western values.

It was quite common for the Linux kernel to panic, 15 years or so ago. I bet that even now it is much easier to make Linux panic than Darwin. HN became way too passive-aggressive in recent years... :(

A very nice reminder that there's no such thing as code without bugs.

Except it is, because your code doesn't work:

  > [10, 1, 5, 1, 10, 10, 1, 5, 5, 5, 10].sort(byNum)
  > [10, 10, 5, 1, 10, 1, 1, 5, 5, 5, 10]

The right way is

  > function byNum(a, b) { return a - b; }

The same can be done with Python lambdas:

  >>> ZERO = lambda f: lambda x: x
  >>> FIVE = lambda f: lambda x: f(f(f(f(f(x)))))
  >>> to_int = lambda f: f(lambda x: x+1)(0)
  ... etc.

You can make it without any 'weaknesses' in Python:

  collection = Transaction.search(
      order_id__starts_with='a2d',
      customer_website__ends_with='.com',
      billing__first_name__exact='John',
      status__in=[
        Transaction.Status.Authorized,
        Transaction.Status.Settled
      ],
      amount__between=("10.00", "20.00")
  )

the implementation could look like this:

  def search(**kwargs):
      for arg, value in kwargs.items():
          action = arg.split('__')
          attr = getattr(self, action[0])
          if len(action) == 2:
              method = getattr(attr, action[1])
              method(value)
          etc.
          .....
