This is the most useless academic 'discovery' I've ever seen. Am I wrong?

How is the engine for BFG different from the older Doom3 version?

I vaguely remember using this knowledge of the scales to "cheat" on the violin. If you move your hand into whatever position puts your first finger on the first note in the scale then you can always move the rest of the fingers in exactly the same manner - whole whole half, whole whole whole half. My music theory knowledge is crumbling but what I mean is if you move into 2nd position on the A string to play a B scale its much easier than starting in 1st position with the 2nd finger.

I did this at a competition once when given some insane scales (like 3 flats in the clef) without having ever practiced the scale itself and got it right.

I tried it on my kubuntu i386 netbook earlier today. The ppa installed ok and when I ran 'netflix-desktop' for the first time the wine installer downloaded and installed mono, then proceeded to install firefox. I noticed some errors but didn't look at them very carefuly.

I ran 'netflix-desktop' again and it said 'firefox.exe not found' at which point I gave up.

Is there a youtube video?

I found this http://www.youtube.com/watch?v=NDGl-eDEuNQ but I'm not sure if its the same game.

They are not homoiconic. The underlying datastructure for many schemes, and racket, is not a list. It is a syntax object. Of course you can still do metaprogramming with syntax objects but I wouldn't call it the same thing.

You can still do anaphoric macros with hygienic macros.

Its disingenuous to call scheme and racket lisps. They have parenthesis and first class functions but the similarities stop there.

So yes I equate Lisp with common lisp. I didn't read the entire article (far too long) but he does mention 'defmacro' which is in Common Lisp.

To understand Lisp is to understand interpreters. With that understanding you can create domain specific languages which is extremely powerful.

But I wouldn't recommend using Lisp itself.. macros in particular are unhygienic.

The major issue he has seems to be that visual studio is much easier to use than the command line + makefiles. Ok that may be but if you are porting to linux then you probably are already familiar with the command line and makefiles. Supporting gcc on windows from a makefile that you already need on linux is not super hard.

But in any case I find visual studio a horrendous piece of garbage.

Also Nacl supports threads while emscripten does not. For a large set of applications (including my own games) this is a deal breaker to using emscripten.

Beej's networking guide is pretty good

I suppose bitcoin could be used as the technical solution. Maybe receivers of money can white-list certain senders so they don't have to pay anything to send to them. Then only spammers and unknown people would have to pay.

Clearly you can't perceive sarcasm.

    $ t
    command not found

clearly they could have named the compiler just 't' instead of the overly verbose 'tsc'. all those extra characters!!

I'm not a network engineer but is this all that difficult to do? I imagine if you control the AS (autonomous system) then you can control all routes into and out of the country, so they can easily block anything out of the country unless it comes from some known IP (like the computers of the elite class).

I don't necessarily disagree with this assessment but you can easily create functionality in C that requires looking at multiple source files to understand whats going on.

    x = foo(bar(), baz());

Now you have to look at the definitions for bar and baz to understand the cost of this line.

I guess this is the trade-off with using a high level language. Expressivity vs transparency.

I spent a few minutes trying to figure out how to install the thing so for anyone that is equally as lost

    $ pip install sh

or goto the github page https://github.com/amoffat/sh

I agree, although I have never had a performance bottleneck related to std::list that required a move to std::vector. Do you know at what point std::set becomes more optimal (in some dimension) than std::vector?
