I don't know Smalltalk well enough to say for sure, it's just my rather vague impression that Smalltalk is more compiler-friendly, likely based mostly on what I've read over the years about this, for example looking at: http

I would like to read an actual in-depth comparison. While undeniably the quality of the Ruby implementation has a long way to go, Ruby has very "loose" semantics and I think some of the optimizations that are possible for Java, Ja

When you have a multiplication of 5-10 matrices that has to be done in the correct order, the expression gets horribly unreadable when written as nested function applications. And those kinds of expressions are ubiquitous in numerical compu

This is just another one of those speculative stories invented out of thin air that are supposed to be plausible just because they illustrate some reproductive advantage of one trait over another and are hence deemed to be "evolutionar

This is simply completely untrue. Newton synthesized a lot of earlier results in physics and mathematics into a unified framework, and he deserves a lot of credit for that obviously, but nevertheless it was a synthesis and not something don

See this discussion: http://superuser.com/questions/343572/how-do-i-reorder-tmux-... It kind of works in the end, but it's arguably a bit more awkward to use than in screen.

This actually works with GNU Screen. Because of this, and because of the lack of workspace reordering in tmux, I seem to be actually about the only person who likes Screen more than tmux.

This idea that a software engineer picks a language as his "favourite" and becomes a "Ruby developer" or a "JavaScript developer" ever since is completely misguided, and I'm sad to see it cherished further

The last sentence from this piece is just beautiful, it has become my personal motto: For a successful technology, reality must take precedence over public relations, for nature cannot be fooled. It captures in a capsule form the reasons

There is no such thing as "true" randomness, in fact in rigorous mathematical probability theory "randomness" itself belongs to the class of undefined concepts like the concept of a line in Euclidean geometry. In the end

Thanks for the great resources. I still wonder to what extent is it at all possible to do cache-friendly data structures on the JVM. Besides the somewhat abstract data structure considerations of the kind posted, there is still the issue of

I edited that part of the comment out because it was not really related to anything, but I meant that all identifiers go into a single (language-level, not program-level) namespace, e.g if you have a struct type called Bytes, you can't

The size has to be known at compile time, though. One can do a slice of slices, but then it's not necessarily continuous in memory. So you are left with allocating a one dimensional array of size x*y and doing index calculations by han

I really hope this will get solved in the language itself, I like Go quite a bit, but there are quite ugly places, all related to generics I guess: - No min/max for integers (and Go doesn't have the ternary operator) - No IsMember
