There's still differences. If you're running it in prod then the functionality has at least gone through code review and you have higher confidence what's running is what you think it is. If you run things from personal boxes

I remember news saying the FAA added supplemental type certs allowing G100UL for basically every engine in 2022. What gaps are there?

Commercial mowers do exist, for example Exmark[1] (some not launched yet) and Toro[2]. Based on the pricing I'd guess the breakeven vs gas is still >3yrs without tax credits. [1] https://www.exmark.com/electric [2]

For an example, my team owns a dozen services and they have hundreds of direct and transient dependencies. Of those, maybe a dozen or two to need work to support the new version but that's a dozen different teams that have to put the w

This is just the data serialization format, you have to build any other functionality yourself. We do have a pattern on a few of our APIs where there's a big fixed schema (i.e. it's just a struct and you can't do GraphQL thin

The SDKs use Smithy[1] which is tailored for defining+generating services and SDKs, Ion is more of a pure data serialization format. It's definitely niche but my org uses it in a few places and it has some nice properties that fit our

The key to sleeping at night is to add metrics and alarms near those cliffs or 'edges of the map' so they aren't invisible anymore. It's hard to anticipate every angle to this but in any case where you're making thi

Everything in moderation I suppose. I've experimented with marking large blocks (2-4hrs) as tentative for IC work a couple days/week recurring and it does help avoid the Swiss cheese of 30m meetings spread across the entire day. L

In a similar vein, in the early days of launching Relay[1] I ended up spending a couple weeks in total squashing timestamp bugs. We were integrating with a few existing systems that used epoch seconds or milliseconds for timestamps and they

The philosophy is "1 > 2 > 0". This means ideally you'd prefer a single thing but single things often bottleneck delivery from different orgs as they have differing requirements. In that case you'll accept overlap&

Not being able to check out customers is a really bad customer experience. It's a double whammy of wasting their time and they don't even get what they needed so it's worth investing to make that less likely. Things are proba
