As a programmer I find constructivism is my default position if I think of math intuitively; perhaps that's why I butted heads so much with many of my math teachers. But, your argument actually makes me less sure of my agreement with it: i

Again, you're not getting the point. Constant time != "fast", it just has to do with how the operation scales with N. The point, though counter intuitive, is that the constant time of the list operation is larger than the linear time of

This reminds me of P and N silicon; the negative frequency light is like hole current. (N silicon has "extra" electrons. P silicon has "missing" electrons that leave "holes", and you can have current where it's the holes that are moving.)

I spent about ten years working on Markov based chat programs. I gave up on themwhen I realized that no matter how sophisticated your statistical model it will never be more than a statistical analysis of text, unless it includes some rich

I was under the impression the accepted reason for Mars losing water was it being carried off by solar wind due to Mars' lack of a strong magnetic field, that lack in turn being caused by its smaller size making its outer core not remaining

This is great. But it would be nicer if the algorithm to randomly place the new messages would attempt to not obscure the most recent ones; sometimes I was trying to read a really interesting message and it got covered up before I finished

I've been looking for an alternative to Ubuntu because I'm unhappy with how paternalistic Canonical has been leaning in the latest Ubuntu releases. This may be a great time to switch to Kubuntu.

I ran into this same problem recently: while looking for a legitimate and very specific car book on Amazon, all of the top hits were strange 3rd party offers to sell the book at ridiculous markup, over $200 for a $30 book. At the time I t

Io has a similar distinction. In the Io language, := is syntax sugar for newSlot and = only means updateSlot. So if you accidently = a slot that doesn't exist, it doesn't new-up a magic global, it raises an error.

Me too. I added a 3rd snake that was black and controlled by the computer. Also made it so the levels wrapped so if you went off one edge you appeared on the other side. The unintended consequence was you could get into the scoreboard and

He's not advocating "auto everywhere", he just said it will make the STL algorithms easier to use (which it will). The other benefit of auto is for generic code (code in templates) where you might not necessarily know what the return typ

Well it's Io but you're still correct, I could fix that by letting enums "decay" into Numbers. In fact, I originally had that happen accidentally and I actually considered it a bug. The reason I considered that a bug was that I made a d

C++ function to compare two enums: bool operator ==(SomeEnum left, SomeEnum right) { return left == right; } In my bindings (in C++): LM_BIND_NONMEMBER_OP(SomeEnum, (==)) In Io script: if( obj property == SomeEnumInstance, doStuff()) The ==

First, because I knew Io and not Lua. I had gotten interested in Io years before. Io was actually my first dynamic language, not Python or Ruby or Javascript. I stopped using Io for a few years when I moved on to other things, but _why's

I'm currently working on a game engine that is a mix of C++ and Io. Here are some things I learned: - By far the most time spent in cross-language calls is in functions that take two integers and return a boolean. What's up with that? En

The striking thing about this is not just that it works but that it works so well . That I did not expect.

I'm using Io in a serious project, it is the scripting language I chose to use for my games. Io's expressiveness and reflection has allowed me to make lots of mini-DSLs to simplify game scripting tasks. I'm very happy with the performance

This simple formula produces an interesting sound in your a1k0n.net player: (t % 1000) & t Multiplying the whole thing by t adds to it. Edit: t >> (t % 8) also produces an interesting sound; changing the number 8 changes the pi

I recently used category theory to clarify my thinking on a difficult type-conversions problem I had in some C++ code that needed to generically handle many different combinations of const/non-const and value/reference/pointer to another.

I was about to say the same thing. Since Io represents the program as an expression tree of messages, you can write macros to operate on the message tree, and they work for Io's syntax as easily as Lisp macros work for Lisp syntax.

I wrote a library that makes C++ callable from script languages, but instead of parsing headers it uses C++11 template metaprogramming and type inference, so it always parses exactly what the types are because it runs in the same compiler a

I hadn't been aware of ChaiScript until now, but its C++ binding techniques are similar to what I developed for my LikeMagic project, a (mostly-)language-independent C++ script language binding project, with Io as its first backend language

Close but I think you have your orders understated. A normal programmer faces O(n^2), while a great programmer achieves O(n log n). Really bad programmers do O(k ^n) amount of work to achieve the same, with k>2.
