Time and space are bounded by gas; that ought to be a sufficient guarantee.

In the last snippet the function returns BigObject&&.

The 'object up the stack' is an rvalue reference. While we've successfully returned a reference into the caller's stack frame (RVO), the object it referred to has already been destroyed. That's why you see 'con

There is another subtlety that values associated with integer keys are stored as an array. dicts and HashMaps don't do this.

If that was his argument I'd be happier with it. As described, his goal was to encode comments in the function name and describe caveats in test cases; none of those steps sound like 'write a javadoc'. Javadoc and comments ar

Your argument is not an argument against comments, it's against any kind of description. Your code works just as well if you assigned each function a unique number starting from 'func0' - that's how code obfuscators or m

IME this also happens not because the function is reused, but because the programmer is trying to create functions at a 'high level of abstraction'. Usually this means one function that has a bunch of descriptively-named function

Since you're already using Lua, maybe you'll have an easier time switching to Terra. It supports SIMD, and you only need to deal with embedding LLVM. http://terralang.org

Well, the correct solution means you never want to examine each ball more than once anyway. It's the kind of constraint you can consider as existing 'outside' of the algorithm.

Seems like the key insight into solving problem 1 is constructing the unconditional jump operation. From what I remember of my Cambridge interview, the questions they asked weren't anywhere near as interesting as these.

IME refactoring optimises for a local minima of code entropy. Any time you want to add new functionality, you're going to have to jump back out into 'mess' to implement the feature, then 'fix' it again with further

Unless I misunderstand your point, how do you create complex data without complex code? I agree with the sentiment, but priority queues don't organise themselves. It seems more like its about the abstractions you use.

I see this sometimes in code at work. As soon as you need to stuff one of the 'const' objects into any kind of container you start requiring unique_ptrs everywhere, and then you start thinking how much easier your life would be if

You can see this with Rust which tries to satisfy the same niche. It's possible to avoid the gotchas in C++ while preserving the advantages, you just pay a different price by working harder to satisfy the compiler.

Describing what they are may be too hard for a HN comment, but what they achieve is easier. Traits are the way Rust supports both dynamic dispatch and static dispatch in polymorphic functions. C++ supports both kinds of dispatch too, but th

Android is the leader by market share but iOS leads mind share. Android isn't a strong brand. Samsung, HTC, Sony, LG et al put their own corporate branding ahead of whatever Android version they use. Amazon barely mentions its existenc

Subroutines are not "named blocks of code" any more than they are facilitators of code reuse. Inline comments around a block of code also matches the concept of a named block of code. The point of subroutines is to gather the code

For that to work, you need to enumerate either the acceptable failures (network timeouts) or the unacceptable failures (logic error). However, for idempotent actions, why does it matter what caused the exception? The worst that happens is y

Aliasing is only a problem because they prevent you assuming two values are independent of each other: a write to one could affect the other, if they are aliased. When you enforce immutability of aliases, as Rust does, aliasing stops being

Nobody says you have to OK with something you mitigated against. I remember on several occasions fighting Visual C++ over code it bombed out on. Having a precompiled header scheme to make up for poor performance. Yes it sucks, but you don&#

Lest we forget, the first engineers relied on folk wisdom and empirical knowledge before rigorous processes and accurate physical models existed. That also means we have a few millenia of catching up to do!

The reason why you bundle installers like this is to catch the 'press yes to everything' group of users. In this case it's done for the greater good (mostly), most users don't care about security updates or upgrading out
