Anyone know what programming language(s) is algorithmic trading software mostly written in? Also known as automated trading, algo trading, black-box trading or robo trading. If I wanted to write the above software where would I start? Any tips/trick/advice greatly appreciated. Thank you in advance ;-) ...
According to this page,it seems that Perl,PHP,Python is 50 times slower than C/C++/Java. Thus,I think Perl,PHP,Python could not handle critical application(such as >100 million user,>xx million request every second) well.But exceptions are exist,e.g. facebook(it is said facebook is written with PHP entirely),wikipeida.Moreover,I heard g...
I was thinking whether it is possible to bridge asp.net, php and java to form a single page. Actually i dont need any such thing as of now. It was just an idea that stiked to my mind as some features of some languages are good and some features or some other languages are good, so i was thinking what if i combine all these features into...
I have heard the term "universal type" thrown around in the context of programming language type systems, does anybody know what this means? Is is something to do with objects like a String where two instances of "foo" are identical even though ("foo"=="foo") may be false? ...
If I design a new language with type inference, no explicit types and no class inheritance support and then want to add inheritance, what are the minimum extra hints to the compiler needed to resolve type ambiguity when adding the feature? Are class names needed? EDIT The type-tainting is traced through assignments throughout the prog...
I'm now thinking to develop a disassembler, but as I know that it's very hard to build a disassembler I want to know the best/easiest language to turn my dream into a reality, also, a tutorial suggestion is very nice too ;-) ...
Hi all! I am looking for various approaches for supporting some level of intellisense on a dynamically typed language. Since intellisense information is based on type information, there are inherent difficulties in implementing this for dynamic languages. Do you know any algorithms or methods to implemented it? ...
In programming languages concept, Sebesta's book states that (Ninth ed., 284): The disadvantage of fixed heap-dynamic arrays is that they take longer time to allocate array from stack. How can we analyze this statement? What is the difference between fixed heap-dynamic and heap-dynamic arrays. What does that fixed word stand for? ...
I have an interview where one of the areas I was told I might brush up on is "dynamic programming languages". So I figured I might spend this weekend writing one to bring as sample code. :-) Of course, given the time constraints, I plan on writing something very basic and preferably using a language and/or toolset that will make it ex...
What language is used to build low level languages like c++ and java? How could you build the first language with no language? ...
That title sounds more argumentative than intended but I don't know enough Lisp to say whether its good or bad. It seems like everyone who has used Lisp loves it yet the most popular languages these days are descended from C. So what is it about Lisp that is so great and why isn't it used more? Is there anything just plain bad about L...
I have to write some code in ML and it is my first time I`m going to use the language. Is there any Development Environment for Standard ML? (preferably under Windows). I tried googling (and stackOverFlowing ! ) but all I found was plain compilers for Linux (at most with an interactive console), but no IDE nor Eclipse/NetBeans plugin. An...
What is the best programming language for writing MIDI-interactive musical application that would be run on MAC and on Windows? ...
there are tons of books out there teaching you a new language. but some of them are just too thick with lot of information and less code. it usually makes you sleepy. especially when you already know the basic syntax and wanna learn how to use a new language very fast. are there good series of books for this? the dummies series is very...
I came to know that eclipse can be used for other languages as well. But will it give the same comfort level as using java? Is there anybody who has used eclipse for other languages? ...
is it possible to translate one language to another with an interpreter? heard that quercus could translate php to java? at first, i thought it was a cheap lousy solution which could give code errors, but it seems that it´s fully possible to do so. could you translate php to other languages, like python or ruby? c++ to java and so on? ...
Background Perl and Ruby have the __END__ and __DATA__ tokens that allow embedding of arbitrary data directly inside a source code file. Although this practice may not be well-advised for general-purpose programming use, it is pretty useful for "one-off" quick scripts for routine tasks. Question: What other programming languages sup...
I hear claims that Ruby on Rails makes web applications ten times faster to write. Is this really true? Do they just make a bunch of tools to make the simple stuff fast and the hard stuff impossible (without serious refactoring)? Can it handle difficult web problems like an advanced searches and AJAX webgrids? Can't other languages j...
Ever since I started programming properly using good old VB6 and up until present day, I often still get burned (and just have) by this in programming: if x == something or x == somethingelse I often end up writing: if x == something or somethingelse Just out of pure interest, does any langauge/languages out there support this? ...
I am already working on some software in Python but I'm having one of those days where I step back and reflect just to make sure I'm not spinning my wheels. I know that Twitter launched with RoR because it was fast to build. Then they almost moved into another language in 2008 because of scalability issues. This has caused me to step bac...
