The problem with most diagrams is that they lack semantics. What do the boxes and arrows really mean? As soon as you start getting fuzzy, the diagram is effectively useless. If you're up for a laugh, try to play "Diagram Bingo&quo

Computing's Climate Savior - really? By their estimate, if every organization in the world put in the effort to transition 60% of their data to tapes, you'd save 79 million tons a year, a whopping 0.16% reduction in CO2e. This doe

Like most of Wolfram's scientific work, it's hard to pin down whether he's a genius or an eccentric crank. He built his own theory of the universe from first principles. It all sounds plausible, but most of the large-scale as

Yes, thank you for the correction! Though the point still stands - keep your nflags <= 2 and you can reasonably test it.

You've described the ideal use case - a single feature flag, short lived, to let select users test one isolated piece of functionality until it's made generally available. Feature flags used in this way are wonderful. But there ar

No. Maybe it matters more on HN where the audience values things like grammar, logic, and empirical evidence. But we live in a bubble. On social media as a whole? Nope. Vulgar, grammatically-incorrect, emotional tirades seem to be the hot t

That's another aspect to it for sure. Those who chose to eat crap suffer the same fate as those who can't afford the alternative. Either way, eat poison = face health consequences.

I don't think "fork" has a consistent meaning, at least not since the arrival of github. In the early days of open source, a fork was somewhat hostile and indicated a schism or lack of confidence in the original authors. Toda

Exactly, some scientists raised the warning flags but were chastised despite being right. The obvious consequence has been a chilling effect - scientists are now heavily biased to understate the problem and most are somewhere between ultra-

The flipside of course is that they HAVE to be discrete. My issue with sprints is that they arbitrarily reduce the solution space - instead of asking "what's the right way to do this?", you ask "how much can we hack out

IMO sprints are a barely-adequate substitute for a coherent vision with priorities. In a chaotic (dysfunctional) business environment where things change on a whim, sprints serve as a firewall to provide a few days/weeks of focus. If e
