[Ilugc] Julia, I Love You

[Shrinivasan T]

Julia is a new language for scientific computing that is winning
praise from a slew of very smart people, including Harlan Harris,
Chris Fonnesbeck, Douglas Bates, Vince Buffalo and Shane Conway. As a
language, it has lofty design goals, which, if attained, will make it
noticeably superior to Matlab, R and Python for scientific
programming. In the core development team’s own words:

We want a language that’s open source, with a liberal license. We
want the speed of C with the dynamism of Ruby. We want a language
that’s homoiconic, with true macros like Lisp, but with obvious,
familiar mathematical notation like Matlab. We want something as
usable for general programming as Python, as easy for statistics as R,
as natural for string processing as Perl, as powerful for linear
algebra as Matlab, as good at gluing programs together as the shell.
Something that is dirt simple to learn, yet keeps the most serious
hackers happy. We want it interactive and we want it compiled.

I like "j".

It's open source, good with arrays, elegant, and so
concise that it can improve programmer
productivity about 10x.

For example, you can write a really small function
to calculate the average of a list of numbers:

$ avg=: +/ % #

Run it with

$ avg 1 2 3 4
2.5

It's like apl with a normal keyboard.

Just 24 hours earlier you could have written the whole thing off as an
April Fools joke...

Just wondered to see the benchmark chart here.

http://julialang.org/

It may be useful when high performance is the requirement.

It's nice.
Thanks for the link.

On a side note, never knew JavaScript was so incredible in performance!

Not just performance, it is also damn good in `readable` code

The subtle connection of this sample code in their page to their namesake
`Julia`(sets) is super cool :)
Julia sets are curves/point sets in fractal planes (planes with fractal
dimensions - how cool is a 2.46 dimension - A human mind can only interpret
integer dimensions, this is 1D, 2D and 3D spaces) which satisfies a
limiting function.
That limiting function is:

function mandel(z)
c = z
maxiter = 80
for n = 1:maxiter
if abs(z) > 2
return n-1
end
z = z^2 + c
end
return maxiter
end

The readability of this code is incredible. Considering the variables `c`
and `z` are complex numbers with real and imaginary coefficients.

Arun

It would be nice to see something like Jacket (The CUDA lib for
Matlab) for this language. Intel's MKL might be fast, but I doubt if
it can number crunch like the GPU.

That could actually be a good project just in case someone is looking
for one.

P.S. One thing I got out of this thread is a reference to the book
Machine Learning for Hackers. I did not know such a book existed
before
