Regarding poor_style(), I've never understood this objection (and indeed I prefer the block style you complain about there). Can't your editor fix this up for you in a few keystrokes? This is the sort of thing that an editor should make eas

You cannot be serious. You cannot go through life letting people walk all over you and abuse your trust. Your approach isn't "better than most alternatives"; it's encouraging him to accept the role of victim. Life is too short for THAT.

In static languages this really isn't a big deal, since you can dispatch based on type. Things definitely get more awkward if you can do things like define new types at runtime, though.

If a .c file includes U x M .h files on average, where U is a number from 0 to 1, then the work we expect to do at compilation time is proportional to U x (N x M). This is still O(N x M).

Absolutely. The claim that the form of government in the United States is a "democracy" is one of the most impressive propaganda successes I've seen.

> There are only two ways to handle this - return values and exceptions - and they differ in style more than in functionality. "There are only two" is a bit strong. Off the top of my head I can think of conditions and restarts in e.g. C

While conventions are useful, different conventions are appropriate for writing different kinds of code, and one should use the right tool for the job. Understanding code written in a functional style is something a good developer should be

If anything it's quite the opposite; most OOP languages are extremely limiting for DSL creation as compared to most FP languages.

As with many corner cases of English grammar, I don't think there is such a decisive answer here that we can call him absolutely right or absolutely wrong, but FWIW his approach ('a' vs 'an' selected based upon the pronunciation of the acro

Rape jokes aren't funny. Even when they involve terrible people like the operators of this site.

Strange explanation of the word "variable" in here. It doesn't mean "many" - more like "changeable". It's the opposite of "constant".

"Smart data structures and dumb code works a lot better than the other way around." An interesting assertion. In your link Guy Steele observes the duality between objects (where it's easy to add new data types but harder to add new operatio

I am unable to reply to my sibling poster, but I believe what you're saying is that having a hideous and unreadable syntax that forces the use of typedefs just so others can understand what you have written is a sign of deep, unfixable badn

You say "we" as if you were speaking for all artists, but you do not speak for me. In my view, the current model of selling a copy of a work to a customer as if it were a scarce good was dubious in the past and is downright unsupportable no

I totally agree with most of this list but I just wanted to let you know that the iPhone does indeed include an alarm clock, and many other time-related utilities, as part of the Clock app. I don't have my iPad here with me, but if I recall

Yeah, neither can I, that's really bizarre. Shouldn't it extend Sum? (which doesn't appear to exist) Can anyone familiar with this design decision shed light on this?

This is just fantastic. Great work. I look forward to see how it evolves further.

I'm not sure I agree that learning multiple languages in the first 2 months of studies is a good approach. I think it's difficult to appreciate the advantages and disadvantages of a language until you've really used it for a while, and I'd

I know that some people feel they still need a watch, either as a status symbol or because they feel it's more subtle in a meeting to glance at your watch than your smartphone, and for them this might be great. For me, though? I can't say I

You seem to be implying that modern GUIs have reached a level of maturity that approximates perfection. I really think that's a bit of a stretch. Why would there be so much effort among technical people to avoid using GUIs, either by using

This is a great explanation of algebraic datatypes! The notion of one-hole context, its connection to differentiation, and its application to zippers is really interesting stuff. Another (much more detailed) discussion of it can be found he

Haha, wow. Went to the Exploratorium today and saw this guy there with his sculpture. Now it's on the front page of Hacker News! What a coincidence. He said that when people ask him when he started building it, he replies "Well, I got up r

A bijective function (also called isomorphic) is a one-to-one mapping between the persons and the bikes (between the domain and codomain). That's the assertion made in the article - that a bijection and an isomorphism are the same thing.

Haven't seen this operator before; reminds me of angelic programming. (see eg. http://portal.acm.org/citation.cfm?id=1706339 ) This also seems like a very natural application of monads.

It seems to me that it DOES pretty trivially give you polymorphism; just change the function pointers in a struct and it behaves differently, while retaining the same type! Inheritance can be implemented, too, by copying function pointers a

by swift 16y ago
Well, function pointers exist in C, though they are certainly a clumsy replacement for having methods (or first-class functions / closures / currying) built into the language.
