Sorry if I was ambiguous before. When I said "log format", I was referring to the message part of the log line. Standardized timestamp, line in the source code that emitted the log line, and level are the bare minimum for all logg

You can't realistically expect every log format to get a custom schema declared for it prior to deployment.

Sure the relative difference between the fastest and slowest approach is 5x. But the absolute difference is still just 125.23 ns. For some perspective, 1 millisecond / 125.23 ns = ~7,985. There certainly are cases where that slowdown m

As you correctly point out, everything you can do with metrics can be achieved via logs if you have enough compute and I/O. But that ignores the reality of what happens when you do indeed have too many logs to use something fancier lik

Graphing metrics and doing transformations/comparisons is (much) faster. Yes, metrics do have to be defined first but in my experience that's a non-issue since the things you want to monitor are usually immediately obvious during

I think the author is asserting that trading away the hackability is worth the faster compile times because faster compiles lets you iterate faster and therefore increases hackability (i.e. put in minutes of effort once and get minutes of b

If they're no longer manufacturing older devices, they're probably not manufacturing parts for them anymore either. The only new iPhone that Apple is selling that's not on the repair parts website is the iPhone 11 which is a

One interesting thing is that First Class Parcels have noticeably faster delivery times than First Class Letters (as long as you both start and end in the continental US).

I've personally experienced three kinds of coding interviews. 1. Trivial questions that can be done very quickly; e.g. does this list of integers contain any duplicate integers? 2. Non-trivial questions that require a large amount of t

I'm surprised Apple supports custom email domains to any extent. Apple is a consumer electronics company. Hosted email on custom domains is very distinctly not a typical consumer behavior.

Can you expand on what you mean by "rent seeking" in this context? Regarding subscription fees, there's nothing wrong with paying for software.

In NYC at least, electric supply charges are distinct line items from electric delivery charges. Consumers do have the option of choosing who supplies their electricity (e.g. namely if you want to buy your electricity from a green source).

For websites, the value is that feature flags should be much faster than the revert/deploy cycle. At $PRIOR_JOB, a revert/deploy or rollback takes tens of minutes of the main application.
