Not to mention, Nim still doesn't have a Wikipedia article because it is "not significant". http://en.wikipedia.org/wiki/Nim_(disambiguation)

The package manager in Julia is great, but the process of making a package needs much better documentation. It looks like Bindeps is the intended way of building packages that have external dependencies, but last time I checked the "do

I agree with you. One needs a group of like-minded individuals who understand and agree on the core design goals, but who have individual say in what they implement. Nim isn't being designed with an inferior model, it is being design

Nim has the feel of a compiled Python (with many additional features that Python is lacking). It is garbage collected, is designed to look as pseudocode'ish as possible. Rust is designed for systems projects where GC is not a good idea

One of the things that kills some of these "completely unknown" languages is that it isn't obvious they are still being developed. The last known release is years ago, or they still only support one platform, etc.

The main reasons I think, are that Nim is not "production ready" and that other developers think of Nim as Andreas Rumpf's baby. In my opinion, this happens when a single author is responsible for most of the implementation o

The hard questions in that list seem much easier than the Google foobar challenge questions. Though of course you have days to solve those, rather than having to solve them during a (presumably short) interview.

The lectures themselves were a fantastic resource. I had been watching them in order, and was about half way through his 801 physics course. They are extremely entertaining and very well presented. He even addresses the issue of sexism at a

I absolutely agree with that. But there can be exceptions. For example the ternary Goldbach conjecture boiled down in the end (after a lot of analytic "pencil sharpening" as the author called it) to an exhaustive computer search u

The issue isn't that there couldn't be life as we know it. It is that life wouldn't have had time to evolve, e.g. the universe would disappear in far too short a time or that the expansion would be so rapid that not even star

Singular is only a component of the project. Maxima and Axiom contain almost none of the mathematical knowledge contained in the Singular project. No one wants to write hundreds of thousands of lines of code in some other system.

Another way you can try Julia online at the moment is William Stein's cloud.sagemath.com If you really want to try juliabox.org you can look at the other post about Julia on the HN page. Near the bottom of the HN comments are some deta

From the article: " A pervasive idea that Julia wishes to shatter is that technical computing languages are “prototyping” languages and one must switch to C or Fortran for performance. The consequences to scientific computing have been

This very much depends on what you want to do with it and what your background is. Here are some things that might bother you. * Julia's approach to OOP is via multimethods, not the usual class/inheritance model. This might be ann

I've been playing around with the Cxx library (currently only works with a source build of bleeding edge Julia) https://github.com/Keno/Cxx.jl It allows you to basically embed ordinary C++ code in Julia code, to i

What you really need is a "solution" that is wrong in just one digit somewhere in the middle that everyone would easily miss when comparing.

You could at least entertain us with a real mathematical problem, even if not the one you were given, e.g. in how many ways can 54673350319220399841294938973353 be expressed as three times a square plus twice a (generalised) octagonal numbe

Actually, looking more carefully at the Fish webpage I think they cite 7 as an example because 7 does not divide 2^32+/-1 (or indeed 2^64+/-1). If it did, the quotient would be a "magic number". However, 7 does divide 2^

You don't need the numbers to fit into a register to use the results from the paper I referenced. The same is true of the followup paper https://gmplib.org/~tege/division-paper.pdf I agree compilers have not used

Compilers have done this sort of thing for a very long time. Here is a well-known paper from 1994 that already tries to do it for more arbitrary constants. https://gmplib.org/~tege/divcnst-pldi94.pdf

The "doom/dread" spoken of is not the doom/dread you are associating it with. Anxiety disorder (regular panic attacks) absolutely comes with a sudden feeling of impending doom/dread. That is its most characteristic

You need something like 14 days for caffeine withdrawal to cease (during which anxiety may temporarily increase). And any effect from changing things about might take weeks to have an effect on anxiety (perhaps up to 6-12 weeks). Exercise (

Aerobic exercise is also great for anxiety disorders, but it is important to note that exercise to exhaustion can severely complicate anxiety, as opposed to depression. The reason is that it stresses the nervous system (producing excess cor

I also agree with the caffeine thing. The reason I stay off it is not so much the immediate effect of caffeine on anxiety (I find none), but because caffeine increases mania. Ultimately mania (dealing with life frantically) causes the nervo

That's interesting. I have had panic attacks so severely that it is impossible to shake them off. My jitters and anxiety about further attacks can go on for hours or even days. I think I have a normal amount of depression ensuing from
