Given that parsing C++ may be Turing complete ¹ I'm not exactly sure that's the best example to use. The world _is_ littered with a million JavaScript and Python parsers. ¹ http://stackoverflow.com/questions/

Off the top of my head: - Not Google - More hackable - Qt + QML looks really cool to me. Android is decidedly not the be-all-end-all of mobile OSes, and an alternative project is always nice.

GLL is fantastic! Unlike Earley and GLR, implementing GLL parser combinators is pretty easy. It's pretty fast and has some other nice features (it can be implemented to produce a lazy stream of possible parse sequences). It is, IMO, th

Interesting, I didn't know about @safe. I need to study D more! At the moment I'm pretty happy with OCaml and learning Rust, but D definitely has me interested (especially when the no-GC stdlib completes).

I… I just got corrected by Walter Bright. That's true. You actually can write an RTOS in D, and it would still be more pleasant than in C (thanks to D's excellent metaprogramming). The problem I have with opt-out GC in D is that i

I agree. To pick a low-hanging fruit, the EU's internet legislation can only have come from bureaucrats completely detached from reality.

Why not both? What if all races commit roughly proportional amounts of crime, but there's a higher density of crime in black neighborhoods? There are way too many variables to say anything about whether “blacks commit more crime” OR

by PeCaN 10y ago
I'm not going to get into a debate if you're going to appeal to the “actual crime rate” vs the “racially biased arrest rate”. There's not enough data to know, and too many interacting variables. It's enough for me to acc

I didn't say D wasn't suitable for writing OSes. Might as well throw Singularity into the list of GCed operating systems. I did say D is unsuitable for real-time and soft-real-time programs, OS or otherwise. You can't write a

It works super well with NoScript, aside from the pricing calculator (obviously). The worst sites are the ones that hijack your scrollbar and use JavaScript for layout.

Last I checked, JSON parsing is not a typical (soft-)real-time workload. Heck, GC probably doesn't even kick in in that JSON benchmark. And yes, I'm aware that Phobos is being rewritten to remove GC. I'll reevaluate D when th

I think this is a valid question. They're pretty different languages in terms of design, but they're definitely worth comparing—their problem domains do overlap in spite of design differences. I've used both, but can't

Relatedly, I highly recommend anyone read Notation as a Tool of Thought¹ if they haven't yet. If I may inquire, what did you work on with APL? ¹ http://www.jsoftware.com/papers/tot.htm

Yes, and VMS had asynchronous system traps for I/O in 1977.² ³ And yes, of course? Erlang could do scalable async I/O in 1988. Alice ML and Erlang both emulate async I/O by having a few OS level threads each switching between

I suspect the influence of Smalltalk and Perl on Ruby kept it from being more SOV-ish. Too bad, since I actually have an odd preference for SOV and OSV grammars. They're easier on my brain. I think "backwards of" gets the poi

They're really not all that different. Both are implementations of concurrency based on data-flow synchronization. Alice ML is explicit about running concurrent promises (it has other types of promises as well) in “threads”, but they&#

Alice ML “threads” are more like Erlang threads than C# threads. They're lightweight userspace threads and you can have thousands of them. That's quite scalable. Also, that's not a new idea. Blocking-style code with async I&#

Alice ML¹ had that in 2000², and the idea of promises/futures dates back to the 70s. async/await to flatten promise hierarchies is decidedly _not_ a new idea. ¹ http://www.ps.uni-saarland.de/alice/manual/

That… isn't an "application extension language" use case. I guess if you count wrapping various C and Fortran libraries it's a "glue" language, but that's not exactly what I was getting at.

If you actually want to develop applications you should probably stick to Common Lisp. SBCL and ClozureCL are extremely high-quality implementations and Common Lisp generally has the most libraries. It's probably the worst Lisp from a
