Outdated how? They were working the last time I made a commit a year ago, I'm not sure what could have changed.

The only collisions I care about in my implementation are asteroid/ship and bullet/asteroid, and they're easier to express directly. The OP's version appears to have many more types of collisions, which makes multiple dispatch a more obvio

Here's an Asteroids clone I wrote in Clojure a few years back, which has less than 400 lines and some neat stuff like procedurally generated 3D asteroids: https://github.com/ztellman/penumbra/blob/master/test/exampl... Some of the design

What about the JVM is such a downer?

Let's talk about Google, then. In addition to having special ways of displaying results for different types of searches (local, geo, weather, shopping, etc.), there are also a lot of different heuristics underlying the search results. I

All of your examples are gestalts . They're not single seamless abstractions, they're patchworks that are more than the sum of their parts. That's precisely what is being proposed here: a platform for creating a development environment th

Unless you're taking the sunk cost of the node.js development into account, I don't understand your point. If the core programming model for node.js doesn't help them in any way, and the ecosystem is less mature, then it kind of misses the

I think the point wasn't that "asynchronous is hard", it's that "asynchronous is just incidental complexity". CRUD apps don't need to be asynchronous, and node.js has a relatively impoverished ecosystem for such apps. There are undoubtedly

If they already have support for Ruby, PHP, Java, Objective-C, and server-side Javascript, then a post that claims Haskell and Clojure are the languages that "really matter" can probably be safely assumed to be a joke.

I doubt they actually think a Haskell client is going to be one that "matters". It's a fun bit of software, take it for what it is. Also, if you google "factual api", you get http://developer.factual.com/display/docs/Factual+Developer+...

Netty has support for zero-copy file responses, I imagine that's at least a large part of the performance discrepancy.

The side-effect could also just be updating a mutable hash-map, which has much of the same issues, and isn't something that you can sandbox.

by prospero 14y ago
There is a valid point lurking in there. The instant evaluation model doesn't play nicely with side-effects. Exactly where side-effects occur can be difficult to determine, there's no simple way to work around this. This is less of a probl

Okay, I've only ever skimmed CTM before, I'll give it a closer look.

From now on, I'm going to start all my questions with "this is either obvious or wrong, but ...". I hadn't made the connection between dataflow and logic programming. I'm not sure if the programming practices surrounding logic programming

I haven't really written about this anywhere, and the code in its current state is far from self-documenting, so I'll give it a shot here. The code transformation is pretty much all local. Since everything in Clojure is an expression (this

Hey, I'm the guy in the video. If anyone has questions, I'd be happy to answer them. Any questions regarding odd numbers will have to wait for my upcoming presentation.

Anyone who likes this would also probably enjoy Stanislaw Lem's The Cyberiad [1], which is the same conceit writ large. I highly recommend it. [1] http://www.amazon.com/Cyberiad-Stanislaw-Lem/dp/B005DI94CE/r...

Seriously? China is the foremost present-day example of state capitalism. A quick Google search brings up http://www.nytimes.com/2010/08/30/world/asia/30china.html .

As the author of the OpenGL Tetris implementation, I have to agree that the use of exceptions for flow control is a little cringe-worthy. I've been meaning to clean that up since I wrote it over two years ago, and still haven't gotten arou

Language fluency, on the other hand, does exist and is very valuable. It shouldn't be a prerequisite for a full-time hire, but not everything about a platform can be inferred from first principles. Understanding the idioms and pitfalls of

You have a very high opinion of the average programmer. I'd say unrealistically high.

The macro example used is meant to be instructive, not a demonstration of how powerful macros could be. Consider https://gist.github.com/1119534 , which demonstrates a pattern-matching syntax that (at compile-time!) constructs a minimal tr

"It's what I had to do to keep my job" isn't some sort of cure-all justification for unethical/criminal behavior.
