https://www.reddit.com/r/explainlikeimfive/comments/33fmrq/e... In computer science, the satisfiability problem is the task of determining whether a boolean problem can be satisfied, that is, made to be true, by some combination of inputs. For example, the expression: A AND NOT B is satisfied whenever A is true and B is false, while the expression: A AND NOT A cannot be satisfied.
A naive approach to satisfiablilty would be to check every possible input and see if the expression evaluates to true.
However, the number of combinations that must be checked is 2n, where n is the number of variables in the expression. This is what is meant by exponential time.
The exponential time hypothesis conjectures that you cannot do better, that is, the number of operations needed to solve satisfiability will always be exponential in the size of the problem, no matter what algorithm is chosen.
If this hypothesis is true, it would imply that P≠NP, because satisfiability has been shown to be in NP, and in order for it to be in P there would have to exist an algorithm that solves it in polynomial time.

For a small mostly-text blog post? Wtf are you talking about? That’s absurd.
Wow what a fun little interesting time. My wife and I made it to the end on mobile!

And from 2010. I missed both facts despite reading the whole darn thing.

Proud of myself for recognizing the conceit (pun intended) here pretty quickly. Good point in the end too!
Did google get slashdotted by hacker news? The “getting started” link at the bottom gives me an internal server error.

I enjoyed this. In particular the drawn diagram and:
> Look at an audio file's waveform before playing it at max volume.
That’s always good advice.
What do you mean by “sanitizing” the sdk’s? Did you remove the OpenTelemetry package?
They do the same thing for digital-only subscriptions.
I've had horrible luck driving cars - thankfully nothing as bad as injuring humans or colliding with oncoming traffic, but I've come close. The stakes - and expenses - are so high compared to other forms of transportation. I prefer cycling although doing it in NYC I don't know if it's actually rationally safer or cheaper than living elsewhere with a car.
OT: Why is this a link to twitter and not to the article referenced in the tweet? There's no other content there.

Thanks for this! Seriously I’m a tab minimalist and this narrative is a great explanation of how “the other half” lives.
You’ve got it exactly backwards. Committees take away autonomy by introducing external influence. Politics by definition is guiding policy, not acting with purpose within the confines of policy.
The most interesting stuff is toward the bottom. I found this fascinating and unintuitive:
> Downranking of Tutorials
> HN submissions which are tutorials are downranked by moderators, as they gratify intellectual curiosity less.
This is brilliant!
It’s one of those things that’s so easy to forget or not even think about but once you see it or think about it, it’s essential.
I’m shocked (and amused) how little of this is comprehensible to me without more context.
That shade map is awesome!
Does it include buildings? (Could it, if not?) I’ve been dying for this for ages.
I found the “subjective” comment easier to understand than this one. Not every opinion or generalization requires citation. Your stance and reply are also subjective. I do prefer quantitative data and references, especially when the topic is at all scientific. It doesn’t automatically make qualitative or broad statements pointless though. It especially doesn’t mean they don’t contribute to understanding.
Can you elaborate on what was so exhausting? This is a super interesting anecdote to hear!
