> Contrast that with Lisp where you can spend at least a day just getting the environment set up in a way that asdf doesn't hate.

I recently re-installed my OS and setting up my Lisp environment (SBCL, Quicklisp, SLIME+Emacs) took about 30 minutes.

Jon pls, do you even Lisp Machine? Seriously, you can't base your opinion on kernels/OS:s written in Lisp on this guy's hobby project. I know what you think of GC, but history shows what an industrial Lisp OS is like and it's awesome.

Considering the feature list, doesn't Common Lisp also qualify as a game programming language then?

Looks like they use defmacro/g! from let over lambda.

Yes but the point is that the (at least I assumed so) 5% increase in speed was based on the initial performance of the system and that it didn't scale. Isn't that basically what you're talking about?

>Say you can either spend X amount of effort on a 50% improvement, or you can spend X/10 on each of 10 5% improvements. Sounds the same, right?

This is the same thing. The point is that you say "10 5% improvements of state S0" in that sentence and then later on you use 10 5% improvements of state S0, S1... S9. This doesn't make any sense, could you explain to me how this would work?

I'd call Common Lisp functional between quotes.

I don't think that any Lisp programmer downvoted him.

Sure, check out pgloader (this guy re-wrote a Python program into Common Lisp and wrote about the experience), the European Lisp Symposium ( http://www.european-lisp-symposium.org/content-programme-ful... ), it's used by Google (ITA, air fairing system), it was used by Naughty Dog for their PS1 and PS2 games (they still use Lisp for scripting), it's been used by NASA, DART ( https://en.wikipedia.org/wiki/Dynamic_Analysis_and_Replannin... ), Cyc, there's a European company I can't remember the name of that uses Common Lisp for its train scheduling system. There's this new Swedish music company that uses Common Lisp for their software.

If you want to see much used applications in the Common Lisp community then check out all of Edi Weitz' software http://weitz.de/

Most Common Lisp that you use is in stuff you don't see, there're no Ruby hipsters here.

EDIT: Oh, or why not something like StumpWm? Really, thre's a lot of cool Common Lisp software out there.

But you won't be allowed to post those apps on the Play Market, because apparently compiling code at runtime isn't okay.

I know :)

I meant "take Java math code and convert into LaTeX, display inline", the first part is the missing one!

The weird thing is that some people feel that they need to find all kinds of justifications for why not having an infix syntax is OK.

Arithmetic in Lisp-style is excellent and easy to read. Thing is that programming languages infix math is ridiculously bad compared to what I can do with paper and pencil. It's really just a really bad form of imitation and to me that irks me way more than just doing it in Lisp. Math written in PL:s is hard to read in general and I'd love to see an Emacs package that lets you show an inline picture as you mark a mathematical expression of LaTeX rendering it as 'regular' math.

First of all: A wide stance low bar back squat going down to parallel together with conventional deadlifts will strengthen your hamstrings and glutes greatly. There are reasons to pull sumo, those reasons are mainly proportion-related. Most people I've talked to who pull sumo at meets usually also train using the conventional dead lift (see for example Dan Green).

Second of all: I'm going to assume that your pelvis suffer from an anterior tilt. If so, then focus more on stretching your psoas muscles since these are usually very tight in people who sit down a lot (and you browse HNews) and pulls on your pelvis. Strengthening your back, hamstrings, glutes and quads aren't a bad idea either, it's just that these are things that usually come with a good training program.

https://en.wikipedia.org/wiki/Psoas_major_muscle

Third of all: The position that is toughest for the lifter is largely dependent on the lifter's own weaknesses. I, for example, deadlift conventionally and have the most trouble to come off the floor because I usually do touch-and-go DLs.

Do you really want a turing complete type system? Being turing complete does not necessarily mean more powerful for real world applications.

The thing about the OP is that Lisp isn't well defined. The only constant is that what Lisp is changes, so it's really not that useful to talk about Lisp as "the final language" because there will always be new Lisps. The only common thing between the Lisps seems to be the s-expressions and metaprogramming.
