Not sure I’ve seen someone so openly hostile on HN in a while. Read the guidelines, and please share your thoughts in better faith.

I don’t see it mentioned here yet in recommendations: Pentax 6x7 is an outstanding camera, especially paired with the 105mm f/2.4 lens. Some of my favorite photos ever have come from that pair.

That’s just a performance optimization because blocks are typically only invoked, not passed or otherwise manipulated. If you want to do anything with the block, you pay a tiny tax and have a Proc instance.

Blocks are actually instances of the Proc class. There are helper methods to handle blocks passed to methods in a lightweight manner but you can also accept the block as a method argument, e.g.,

  class Integer
    def times(&blk)
      i = 0
      while i < self
        blk.call(i)
        i += 1
      end
    end
  end

But in general, ruby code only passes anonymous functions and, in those cases, the syntax is beautiful.

We spend a large portion of the federal budget on human death prevention. It sounds like hyperbole, but anyone dying from administrative changes is literally “world ending” for them.

If a plan to cut bureaucracy was somehow analyzed to find that we could save 5% of the US budget in exchange for 10,000 lives, reasonable people might consider otherwise. To take these changes against life-saving organizations without first analysis of consequences is pretty reckless.

Yes, and only next day settlement. Because there’s no real time authorization, payments have two business days after settlement for the banks to report ordinary failures like insufficient funds.

How quickly a bank responds in that window depends greatly on the bank. In practice at decent scale, we see banks using every possible hour of that two day window to fail transactions.

An ACH debit made on Friday night technically has until open of business Wednesday to fail.

ACH has many of the same consumer protections as credit card networks. The window is 60 days instead of 90 days and the dispute outcome is always in your favor—merchants cannot respond to the dispute or win.

Also, you're self-aware enough to ask if it's you or not, without an obvious bias towards it not being you. That makes me think you're doing pretty good.

Empathy and a desire to be a better human are underappreciated values in this industry. I’ve made this a pillar of interviewing at companies I’ve worked at over the years; it’s better to hire kind people with a capacity for growth and skills in the right direction than to hire folks with all the necessary skills and experience at the time of hire but with poor social skills or a lot of dogma.

Agreed. I buy 5lbs from them at a time and keep it in the freezer. It’s usually frozen two days after they roasted it. I then refill the hopper on my grinder as necessary and use a pour over (chemex with a metal filter). It’s fast and easy and tasty. But I will also drink any coffee and enjoy it.
