You assume that Alice is the sole provider of the product, which is by and large false. In practice Alice shows an ad to Bob at the $2 price point, while Claire and Darcy have the same product for $0.5. Furthermore, Alice creates an entire

The people of ADVERT_CO work hard to distract and confuse my attention such that I overpay for the products they push. For every ad-supported site out there, I'd be better off by directly paying them money for their service. This is ba

No. I'm upset if it's not shown. I write 1 star reviews as well. There appears to be no commitment to show reviews fairly instead of selling 5 star reviews to the higher bidder. Compare and contrast with the care for fairness in

The algorithm only requires 12 holes, and scales the number of holes logarithmically. As opposed to make one group per unit, which scales the number of groups linearly. Less holes, less work, win. If you squint your eyes a bit, you can even

I can rephrase as well. I'm not going to rush your interview code to production, but the review cycle needs to start with a first version. We'll refine as needed, but this is a simple enough problem to expect well-structured code

There is "crappy" as in buggy / overcomplicated and there is "crappy" as in lean, simple minded LRU that just works. The latter is production-ready high quality, even if it may be not tuned or optimized. You can twe

There is one construct for repetition in Go. It's called "for". parser = ParserNil; for i := 0; i < 10; i++ { parser = ParserSeq(parser, ParserSeq(parseComma, parseInt)) } PS. I'm a complete Go newbie. Don't take

The point is to not (re)invent little languages all the time, but to use the actual language. For coroutines, see https://sites.google.com/site/gopatterns/concurrency/corouti... . The parser combinator is also interesting. A parser combina

I'll bite. What are useful uses of monads, other than implementing exceptions, async, state and IO? Granted, it's aestethically pleasing to have a really tiny core on which to layer more sugar, but sometimes using the language as-is suffice

Does panic isolate gracefully a query-of-death, or does it take the entire server down? Does panic provide the stack-trace?

Yes and no. In practice, you're going to fold into a different domain, which causes the types of the reduce function arguments to be different. Moreover, you are not going to have your reduce function conveniently in a library. You are goin

What is the "fold" variant in Ruby? Maps are trivial either way, but folds are a pita in my functional programming experience.

by pacala 14y ago
For loops have been parallelized for quite a while. Having a dataflow analysis tell apart a "map" loop from a "fold" loop is quite trivial once you have the framework in place (aliasing not withstanding). Heck, Fortran is all about for loop

On the flip side, I had to scratch my head on what "&:" is supposed to mean. Or perhaps it's "&" ":". I know, I'll Google it </yeahright>. More seriously, "for ..." maps into "map", "foldl", "foldl'", "foldr" and perhaps oth
