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.

kaiuhl | 5 months ago | on: Ruby Blocks

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

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.

kaiuhl | 3 years ago | on: Stripe Financial Connections

I work at one of the companies that integrated Financial Connections during its beta, moving from Plaid Auth. We use the link to bank accounts for instant account verification and as a fraud signal for ACH payments. However, we definitely can’t do a better job than Stripe could at risk analysis, provided they had access to metadata on the bank account when processing the payment and could provide insights from their entire platform. Now they do.

I’d guess the big benefit here, besides taking some of Plaid’s existing customers, is what’s possible now that Connections lives alongside the other things Stripe offers like ACH, loans, and identity verification.

This sort of shaming about how exactly someone should be, and how they’re failing to live up to expectations by not doing what parent is doing, is presumably exactly why this material exist. Thanks for illustrating to everyone why this might actually be useful.

kaiuhl | 10 years ago | on: About those lava lamps

Left alone to our own willpower, most of us would be less accomplished. We'd live in dirtier houses, wash the dishes less, and treat ourselves less well. It's the promise of others seeing our accomplishments, being around our mess, or seeing us naked that keeps us doing right by ourselves. Doing chores is a chore, but social pressure and acceptance is a powerful drug.

kaiuhl | 11 years ago | on: At some startups, Friday is so casual that it’s not even a workday

Sunday was just an example. Nobody is stopped from working if they're movitated to do so, but we generally discourage each other from working overtime unnecessarily. I personally work 32-hour weeks regularly and still contribute meaningfully.

And then, I go backpacking or bike-riding or something that tends to be demanding physically and relaxing mentally—I find it helps me keep a healthy balance. I know there are plenty of people that don't crave that reprieve though, and that's totally okay as well.

There's weekends where I'm working on a particularly interesting problem where I'll work through the weekend because I want to. The big difference is the extrinsic pressure is missing. Nobody has to.

As someone who was also diagnosed with skin cancer recently and who's mother is dying of metastatic cancer, I can particularly relate. It's amazing that simply being told you're sick can physically make you so. If you want someone to talk to, I'm available. Contact information is my profile. Good luck.

kaiuhl | 12 years ago | on: Facebook Paper's gesture problems

Simple solution: swipe up on the carousel to make the cards full-screen, then browse. The whole UI works on this paradigm, so it may not be obvious at first, but it will be if this style of app continues.

kaiuhl | 12 years ago | on: We work a 4-day week and just raised $4.75m (2012)

I've worked 40 hour weeks in a corporate environment (where it's often actually less than 40), 60 hour weeks in an agency, 32 hour weeks at Treehouse. I find that needing to physically commit to work five days a week is the crux—it makes very little difference how much time you're spending in the pursuit of it. I'm big into backpacking, so three full, available days makes a world of difference to me, not the amount of hours I'm expected to work.
