Scripting languages are languages that allow you to send commands directly to a system that executes these commands. These commands are read line by line and executed. An error is issued when a line cannot be executed for any reasn (wrong syntax, illegal operation,...). e.g. Python, shell-script, Matlab
Programming languages are languages that allow you to create a program by writing structured code that is read all at once by the system, checked for errors, and translated into an unreadable format that the machine can then execute. e.g. Java, C/C++, Visual Basic...
Programming languages are generally faster in execution than scripting languages but are often more difficult to use and have more rigid syntax. You can generally use either of them to do pretty much anything, though each is more suited for specific applications.What are the differences between scripting languages and programming languages?
A scripting language executes a series of commands - usually to the command shell of an OS - like a weekly backup of all files newer than 7 days old.
A programming language allows the writer to create an application which uses functions usually not part of the command shell, such as opening files and manipulating the data within them.What are the differences between scripting languages and programming languages?
The short answer: These days, the line between a scripting language and a programming language is blurred. As such, in practical application, the differences are meaningless. So the answer is: no.
Some details 鈥?what a nerd might tell you: Scripting or writing scripts, is programming within a program. Traditionally you would write scripts to automate certain functionality within another program. Traditionally scripts would have very specific task like for example: reading a text file to extract all the email addresses.
The primary difference between a ';programming language'; (C, C++, VB etc.) and a ';scripting language'; (PHP, ASP, JSP, JavaScript, VBScript)is that code written in a programming language needs to be compiled before it is run. Once it is compiled, it can be run any number of times.
Scripting languages, on the other hand, are interpreted at run-time. This means that every time you want to run the program, a separate program needs to read the code, interpret it, and then follow the instructions in the code. Compiled code has already been interpreted into machine language, so it is will typically execute faster because the conversion into machine language has already been done.
Markup languages (HTML, XML) are somewhat different from both of the others. A markup language is simply a set of tags that are used to ';mark up'; text documents so that sections of text can be logically arranged and labeled. These documents can be viewed as plain text, or, more commonly, are viewed through a browser. The browser parses the document, looking for markup tags, and it then arranges the text and/or formats it according to the values in the tags.
A scripting language is considered an 'intrepreted' language. Each program step is executed as it is reached, and the host 'interprets' the command right then.
A programming language requires a compiler which translates each command during the compilation process and produces a program, typically an .exe file which can be run as a 'stand alone' program.
Firstly, a scripting language _is_ a programming language. I think though you are trying to determine the difference between a scripting language and a compiled language. The difference is simple:
Compiled languages must be compiled before they can be executed - this means you run it through a compiler and it converts your source code into executable machine code.
Scripting languages are interpreted - this means they are only compiled ';on the fly';, line-by-line as each line is executed. For this reason, code written in scripting languages will almost always run slower than it's equivalent compiled language code.

What programming language should I learn?
I want to learn how to develop Windows based software, but also web applications in general. What is the best, most flexible language to learn to get started? I don't want to spend months and months learning a language only to find out it is not useful anymore.
Thanks! NickWhat programming language should I learn?
first Learn VB6/VB.Net. It's easy to understand the programming and
you can build for both web application and desktop application.but, VB6/VB.Net not programming language then learn C/C++ and then Java. this is programming language.
Online study in programming language.
VC++ Tutorials / UI Samples:

http://www.idevelopment.info/data/Programming/java/PROGRAMMING_Java_Programming.shtmlWhat programming language should I learn?
I can never express this enough. Do not learn a language. Instead learn algorithms and patterns. I apologize now if you are an experienced programmer. Learn the algorithms to code instead of the pickiness of a single language. Don't trap yourself in that one language.
Now to learn windows coding and web applications. I would suggest learning C#. Other code to look at however is Visual Basic .NET, and possibly ColdFusion (I have seen it used heavily in web applications)
I hate to break the news to you, but there is no easy language to learn when it comes to web design. I have found that the most flexible language is A++ and advanced versions of C++. Windows at one time had a web design maker that come with 98 and ME. Try and seek those out. There are some web design software's out there that can help you as well. Try finding one and go from there.
Bill gets my vote too. (I'm a programmer.)
I think ActionScript 3 / Flex / Flash is fun. There's a good online community. It's cross-platform, and it's causing quite a buzz. Flash Player 10 is awesome.
VB.NET and C# are just for Windows, and although people in suits tend to like IIS, most developers I know prefer PHP.
I liked Scorpio4frenz's JavaScript suggestion too. You can even use it to develop Adobe AIR applications that run on the desktop.
I've recently started to take up Adobe Flex. It's kind of difficult to work with at first but produces AMAZING sites. Not only are its productions very nice to the eye, the programming features of the language are amazing. I would consider this to me a next-gen web application language. Volkswagen's website was done in Flex.

Do you have knowledge of HTML? If not, start with that since it is the basis of web development. Then you can learn JavaScript without which simple HTML code cannot do much. After that, you might be in a better position to decide whether you want to advance further in Java, .NET, or Oracle web development technologies like Application Express (APEX). Oracle APEX is very simple to learn (oracle provides online workspaces to use it for free..check oracle website), but you do require database knowledge and PL/SQL. But then, you would need database skills for any kind of web development.
I have to agree with Bill. Learning the algorithms and patterns is the most important. once you've got that down. most languages are a piece of cake. you just have to figure out the the syntaxes of the different languages which will, over time, come quite easily.
Learn VB.NET. It's easy and you can build for both web and desktop.
Yea learn VB .Net its the easiest one to use

How is math implemented in computer science and programming?
There is a definite link between computer science and math. (I minored in computer science.) Computer science is based on math.
This is what one website says:
Computer Science
Computer science is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Mathematicians, with their training in logical and precise thinking, are highly prized in this field. See the student section of the Association for Computing Machinery for career advice.
There are definitely more links than the one provided below. just google ';careers'; and ';math'; and ';computer science'; and you'll see many results.
good luck

Which programming languages are used most in bioinformatics?
i want to escape the bench! i think the computer is a suitable refuge, i think if i knew more about the programming side that could help, so i am going to try to learn some programing, which langauges wold be useful to learn for bioinformatics?Which programming languages are used most in bioinformatics?
Must know languages C++, SQL, HTML, PHP, Javascript
Helpful languages Python, Gambas, XML, Smalltalk, Java
Skip .NET as it'll be unsupported in a few years. M$ doesn't like to keep languages around very long so they can sell you a whole new language with almost no backward compatability.
The other languages are good choices. C/C++ is important to know at least a smattering of if you program at all. SQL is a must learn for any language. Start with ANSI SQL as it will give you a firm foundation of the concepts and will apply to a greater or lessor extent with all the SQL Varients like PLSQL.
When learning SQL this book cannot be beat.
http://www.amazon.com/Practical-SQL-Hand鈥?/a>
Python is a handy language to know even as just a computer user. Gambas if you run Linux is a language you can learn quickly, is quite powerful and easy to use, it only runs on Linux at this time. Java is not a language but an institution. I suspect nobody knows everything about Java programming. Even knowing everything about a specialty in Java programming would be difficult. It is a vast language. If you know C++ Java will be easier to learn. It's excellent for web based apps and has better portability than most languages but is complex in deployment.
PHP is another language you'll want to know. It is the web development language. Writing in any other is mostly a waste of time. .NET will be unsupported as M$ forces everybody into it's propriatory version of cloud computing. Cold Fusion is basically obsolete. Writing whole websites in javascript is begging for headaches.
You will do web development, no way around it in todays world. Somebody finds out you know anything about coding you'll be hit with some web development. As such you should know not only PHP but javascript. It's not Java at all and essential to augment other languages. HTML and XML are two other must knows but both are rather easy to learn the basics of.
Smalltalk is a very different bear but it's ability to create agents with self modifying code is quite useful in data mining. Smalltalk is much better supported and easier to learn than LISP. Smalltalk is well supported on most platforms where LISP is only supported on Windows in commercial form. Linux support for Linux is pretty decent including commercial versions, however graphics libs tend to be it's achilies heal on all platforms. Smalltalk comes without those headaches and nightmares. Smalltalk under Linux has some good IDEs to work from.
Last you'll want to at least dual boot. Linux provides far too many tools and advantages in this endeavor to ignore. Many of your end users will be Linux users, possibly the majority today.Which programming languages are used most in bioinformatics?
This benchmark compares the memory usage and speed of execution for three standard bioinformatics methods, implemented in programs using one of six different programming languages. Programs for the Needleman-Wunsch algorithm, the Neighbor-Joining tree construction algorithm and an algorithm for parsing BLAST file outputs were implemented in C, C++, C#, Java, Perl and Python.
A survey (bioinformatics.org) on which languages would be the most useful to learn ranked the following languages in decreasing order: Python, Perl, Java, C/C++ and the framework .NET which includes C#.
Requirements:6 programming languages: C, C++, C#, Java, Perl, Python
3 programs: Needleman-Wunsch global alignment algorithm, Neighbor-Joining tree algorithm and BLAST parsing program.
2 Operating Systems: Linux (Fedora) and Windows (XP)
To start off, learn C, C++, or Java (or all three). They are the basics for just about any programming language. Other than that, I would assume you are planning on storing a lot of data using bioinformatics, so possibly look into storage based languages such as SQL. But once you know one language, it seems that most of them are usually similar in some way. C, C++, and Java are definitely where you should start though.
OK - in order of what works best or what languages would be the most useful to learn. The general opinion would be the following languages ranked in decreasing order: Python, Perl, Java, C/C++ and the framework .NET which includes C#.
I'd suspect its matlab. But you have to have the math and biology background to use it. Programming shops are highly individual and sometimes contrary to what one might think. If you have a particular shop in mind, ask

Can I add one channel to my dish programming?
I have Dish network I my programming does not include the Disney Channel and I would like to add it. I just need that one channel. Do you think I can call and they add it for me for just a fee?Can I add one channel to my dish programming?
No. You have to buy a package. There are a few stations that are offered separately but that is not one of them. If something is part of a package it is not offered separately.
The only way they can keep prices down is to make you pay for channels that you don't watch along with what you want.Can I add one channel to my dish programming?
Yes, on the screen it says call ... for this channel. I'm not exactly sure if that channel must come in a package, but probably not. You might as well call and find out.
Good Luck, maybe your getting ready for Highschool musical 2 (just a guess)
Matt
I don't think Disney is offered as an a la carte channel from Dish. You may need to upgrade your programming package to get Disney and some other ';throw-in'; channels.
yes, call them

If I buy and HD Tivo with a cable card, will I still be able to use On-Demand programming through Comcast?
I'd like to save money by replacing one digital box with an HD Tivo, but I don't want to lose the functionality of On Demand programming. Is this still supported?If I buy and HD Tivo with a cable card, will I still be able to use On-Demand programming through Comcast?
Your cable provider will still be Comcast, so if you have a cablecard you can do everything you could do with a set-top box.
Instead of paying $5/month DVR fee to Comacst you will pay it to Tivo.If I buy and HD Tivo with a cable card, will I still be able to use On-Demand programming through Comcast?
nope, but you will be able to use on demand from amazon.com video on demand. and you get youtube and netflix.
you can also hook up the tivo hd to a antenna for free hdtv.
TOOTAl2 is correct, TV_Guy is nt.
You will not get two-way services from Comcast, instead you get them from TiVo or 3rd party providers from the Internet.
