STM's a good one. I'd consider I/O and State as solving a self-inflicted problem -- I can have side-effect-creating I/O and State in just plain C with barely any type system.

Follow-on question, are there any useful monadic constructs not tied to collections (including optional as you said)?

Hey, thanks for filling in. So basically a facade over the original object only masking some fields.. yeah, not really my cup of tea personally, I'm fine with approx the same amount of code for a boring builder and/or constructo

You mind pasting an example? I typically find higher kinded types, monads etc to be more of a pain than the problems they're solving (builders & constructors not really that painful IMO), but am really trying to keep an open mind.

Java 8 has lambdas and lots of streaming functional comprehensions like map, filter, fold etc. That sounds like all the functional stuff Scala has, right? What's it missing? Also, since when does 'functional' mean 'alg

What's Scala's superior alternative to builder patterns? You can have lots of final members in a constructor in Java, too..

Additionally, it's not a religion. Every programmer should be exposed to Unix style programming just like every programmer should be exposed to functional programming. 100% purity in either case is just creating unnecessary problems.

Fracking is new tech with a ridiculously short path to profitability, you pump the oil and you sell it. It's just good business to pump money into fracking (maybe bad environmentally, but that's beside the point). I wasn't

But it didn't devalue the dollar, inflation's been really low for the last 7 years. Honestly it doesn't make much sense, and should really make people hesitate to pursue deflationary measures. China's fiscal policy does

I'd agree with your first paragraph and disagree with your 2nd one with the exception of the tech bubble -- it's been really, really hard for normal businesses to get bank loans even when competing with 0.1% interest rates from th

You already got the payoff, look at some charts of gdp and employment figures from 2008-2012. The downward slide was stopped and the slow recovery started, exactly the opposite of what the naysayers predicted. In other words there was a hu

Stimulus compared to what others wanted. Indeed since 2010 we've been cutting lots of domestic spending but you wouldn't know that watching TV talk about socialism, so people have been calling for crazier cuts while predicting do

Sure, 'wasteful' anything is probably, uh, wasteful. But there's a long history of successfully executed stimulus, VERY MUCH INCLUDING the recent one which was supposed to lead to hyperinflation and the end of society as we

I think you need to justify that statement, what about type theory says that Go can't have generics? As a follow-up, would the same logic have proved that Java 1.4 couldn't add generics?

Here are my thoughts: America invented the transistor and Internet with tax money, plus educated most of the engineers who built those products up to grade 12. But everyone acts like it'd be some moral tragedy for Apple to pay taxes b

Every product exists to make/save money for its owners. Apply pay and stripe are no different. The glaring question mark is whether a consortium of retailers, none of which are that strong in tech, can actually make a product that ho

Just to throw it out there, I thought communication across 2 cores on different sockets is generally regarded as impossible in less than 100ns regardless of language? If you're staying in L3 on a single socket, I could believe it, may

Yeah, and as always, it comes down to energy -- there's an established way to turn CO2 and H20 into Methane and Oxygen, given enough energy for input. And SpaceX has put some research into methane-fueled rockets already. So some peop

Because libertarians define themselves in terms of pure ideology? US modern liberalism, on the other hand, has basically no pure ideological component other than beliefs in humanistic morals, pragmatism and empiricism. (And, of course, pan

Yeah, but with C's old-school int values for errors, you can always make an equality comparison. The error interface in Go doesn't specify equality, so you can do "if err == io.EOF" in some cases and you're up a cr

A lot of people do argue that about big object-class hierarchies and inheritance, and they've been declining since the mid-2000s at least in mainstream OO languages like Java and C#.

While we're making doc requests on this topic, could you address passing function pointers between C/Rust at some point? Sorry if this is already obvious to more experienced Rust users.

Invalid comparison. Failure to prevent something is not the same as personally perpetrating it.

I hear you RE: compact source code, and that as much as the benchmarks are why I use LMDB (thanks) and not Rocks when I have a need. I was under the impression that Rocks manages more compact storage, probably as another consequence of all
