I know it's a rhetorical question, but "Unicode didn't exist when C or C++ were invented" is a really good answer.

Wait, that's it? The difference between bad (with italics!) and awesome is being able to reference the garbage half of a multiple return?

Well, we seem to disagree on the usefulness of those items and the quality of SBT's solutions vs the pain of rebuilding an entire new build/deployment stack and fighting through all the bugs you've created. We'll just ha

If you're motivated to wade this far down the thread, but can't be bothered to explain one concrete benefit in one sentence, I've gotta assume it's pretty difficult to come up with one.

Not yet. You wanna show me the better solution than Maven? Something that manages multi-module projects, with various versions of dependencies, and packaging as war/jar/tgz/whatever? I've probably spent way more time c

SBT is probably the best example of the total immaturity of the Scala community in terms of real-world engineering. Hey, we're building for the JVM, we've got Maven, it's arguably the best solution in any language for a very

There's no such thing as a Scala shop, there are Java shops and Java-and-Scala shops.

Traditional immigration proceedings? You mean the system where if you're from China or India, you have to wait 3-5X as long for a green card as people from western europe? Yeah, that system sounds great. Dunno why people in software

Actually, funnily enough, the Constellation program got it's big funding push under Bush, while he was talking about all his typical Republican things. Then Obama showed up, cut Constellation and privatized the launch industry, to crie

It's missing the ability to publish or lock to a particular version, which is a game breaker for shops with >5 people, and the go maintainers don't seem to see it as a problem, making it a permanent game breaker.

Well, then there's BlockingQueues as noted above. Callables, Runnables and BlockingQueues are a great setup for CSP-style concurrency.
372.
by jbooth 12y ago
Doing concurrency right is very, very easy in just plain Java. ExecutorService is all you need, it's even 100% FP as long as you remap "anonymous class with 1 method" to "lambda" in your head.

Yeah, but an assumed 10% rate of return with no risk is still ridiculous. How come the government can sell t-bills at sub 1% interest? They wouldn't be able to sell a dime of debt if those numbers were anywhere near reasonable.
374.
by jbooth 12y ago
Declaring that "government is the problem, just privatize it" without bothing to think through or research anything about the actual issue is the political equivalent of "just use node.js and mongodb, it's web scale&quot

My memory's fuzzy, but wasn't there a court case 50 years ago that explicitly decided "outside of envelope is public, no privacy, inside is private, reasonable expectation of privacy"?

They can hadoop fs -get it or query it from hive. Because you want to coalesce all your model updates for every pass over the data, the long startup-time for hadoop jobs actually plays into this. You can have hundreds of millions of sample

by jbooth 12y ago
Doesn't need it. If you're computing a linear/logistic regression via gradient descent, performance-oriented C code on a single machine using local filesystem/caches will beat a hadoop-based algorithm for just about any

If the efficient market hypothesis is confounded by moves like bailing out Coca Cola, what good is it?

I'm seeing I/O as "side effects with possible random error conditions". I really don't see how that squares with functional purity. It's late on EST but I promise if you put effort into explaining a higher-ord
380.
by jbooth 12y ago
Point being, I/O doesn't square with that concept. For some reason, every time I point this out, I'm accused of not appreciating the beauty of pure functions. I love pure functions. Maybe they're not appreciating the

by jbooth 12y ago
So how are errors handled?
382.
by jbooth 12y ago
Hey, so I agree with your analysis in general, and sorry for being opaque earlier (was at work), but you totally got what I was driving at and explained it probably better than I could have. The one thing I disagree with, in many server app

by jbooth 12y ago
Well, that's good, sorry for asking. I've had a lot of people point at the big-0 notation of that linked-list append and tell me that it's faster than an ArrayList append on average. Usually this is right after telling me t

Personally, I view the collections library as a showcase for how that language works when you're designing an API to be used for 3rd parties. If it's incomprehensible, that worries me. If the collections API is purposely trying t

I inferred that you probably use standard library collections. Not really an insulting inference, it'd be insulting to assume you didn't. Personally, I make it a habit to always read (or try to read, in this case) standard librar

Actually, I hold exactly that opinion about C++ :)

by jbooth 12y ago
The claim was that scala code is very difficult to read and idiomatic scala code, as evidenced by their collections library, brings along a ton of conceptual overhead that creates much more complexity than it eliminates. That line alone dri

I agree that Option types are great, so great that I'm happy to work in a much 'weaker' language, use option types, and solve 90% of the problems that more 'theoretically robust' languages address with none of their

It's from the standard collections library, the most-used code in any language. It is in fact representative of the vast majority of code you use. The fact that it wasn't immediately clear to you that a lot of your code DOES use t

Here's a random line from the Scala standard collections library: def :+[B >: A, That](elem: B)(implicit bf: CanBuildFrom[Repr, B, That]): That This is from the standard collections library. In Java, I've got a List.add functio
