• Benefits of using the same language for client and server?

  - by Makita

  I'm looking at architecture solutions for a mobile project that will have a web-service/app in addition to native apps. I've been looking at various libraries, frameworks, and stacks like jqm, backbone, parse, and meteor. Meteor, sort of an "open stack package framework", is tightly bound with node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail, any explicit examples or links would be greatly appreciated, thanks!

• Which is the best non-java, dynamic, programming language to build attractive GUIs?

  - by VeeKay

  I am well acquainted with java and groovy but somehow I am not intrigued by the performance or looks of swing based applications that are developed on the same. So I want to learn and know about THE best alternate dynamic programming language (coz I am looking for little bit of luxury while writing code by not willing to fiddle with pointers, memory handling, static typing difficulties etc) to develop attractive cross platform GUIs. To be precise, when I say attractive I mean support for elegant translucent windows and nicer components (not the flashy adobe stuff). Can you please suggest me a programming language that manages to fit into this?

• Which language is productive for high phase business application development? [closed]

  - by Nizar

  If we (I and my friends) would like to build web-based products and sell it using a license approach (to renew every year for example). Which server-side language will be most suitable for our purpose? We could target the following audience: - Personal sites. - Serious small-medium companies (to sell prducts such as Help-Desks, Forms,etc.) - Restaurants (to sell online order web applications). We would like to - attract as many customers as possible. - provide updates for our prodcuts (for our customers). - make our products easy to use. There are number of open-source frameworks and languages that has potential to handle our business problems (like Django, Python, Java, etc..) However, we are not sure which one is easier to learn and has variety of tools/plugins to help us in development process. Thus we need to get you experience on this hard to decide matter. Which language and its supporting framework we should choose ?

• What is a *slightly* less extreme equivalent to being "fluent" in a language?

  - by Mehrdad

  tl;dr: What is a less extreme (but still noticeable) alternative to the word "fluent", when saying e.g. "I am fluent in C++/Python/whatever?" I think I can call myself "fluent" in C#, because I know the language and runtime very well, and I'm very familiar with the .NET framework's APIs and classes, etc. I would like to claim the same thing for Python and C++. But while I can program in Python (I did so for an entire summer, making a website with Django), for example, I would not call myself fluent because my code isn't always "Pythonic" (e.g. using map/filter vs. list comprehensions), and I'm not too intimate with some aspects of the language and standard library yet (e.g. the introspection API, etc.). Is there a word or phrase I can use on e.g. a resume to describe what I know? I can think of "very familiar with", but is there a better word/phrase I can use?

• What server-side language should I learn to be able to start big user-input websites (like twitter, facebook, stackexchange...)?

  - by DarkLightA

  I'm thinking ASP.NET, but I don't really know. Can someone tell me what a good server-side language for the "Zuckerberg-dorm-room-starting-up-a-huge-website" deal? I know the latter used PHP, but as I've understood it that's kind of outdated and C#/ASP.NET is a better way to go about it. Is HTML + CSS + JavaScript + C#/ASP.NET MVC + MySQL a good combination for it? Is MySQL combined in ASP.NET MVC? Also, where's a good tutorial for the server-side language you suggest? As mentioned previously it has to be able to handle massive user-input without much fuss.

• I need a multi-language site with webshop functionality. Which CMS to choose?

  - by ec30

  I need to develop a multi-language site which includes simple webshop functionality. I have extended experience with WordPress. There are numerous shopping cart plugins available for WordPress however none of them is compatible with multi-language plugins such as WMPL. Drupal is an option I looked into (using i18n and Ubercart) and I am not sure this is the solution I am looking for. Another solution I considered is to develop a custom WordPress cart plugin that is compatible with WPML. Anyone familiar with this situation? Any recommendation regarding CMSes that fit my needs? Thanks!

• Should you apply a language filter to a randomly generated string?

  - by Tim

  A while back I created a licensing system for my companies new product, as well as all products after this one. As with a lot of licensing systems mine generates codes: 25 character product and registration codes, as well as 16 character module unlocking codes. My question is, since some parts of these generated codes are random should I apply a language filter to it to avoid any embarrassing language being given to the end users? I chose to as it was not difficult at all. But has anyone else ever came across something like this? Any viewpoints as to if it is worth the effort?

• PHP or C++? I just want to choose a language and focus on it!

  - by user19177

  I love C++, but I feel I don't know if I should focus on web, so PHP, or C++. It's just an hard choice because right now I want to focus on one language and don't want to switch it a few months later. With C++ I'd program in SDL, while with PHP I don't know yet. I am not a very advanced programmer but I know basics of programming and can get going very well if determined. The problem is I just don't know.. I'm like OK! I'll go for C++! Then a minute later, wait what if I went with C#? Why this that.. ! I've read milion threads about C vs VB C# Python Ruby etc, all of them which I could find! It got me nowhere. The problem is probably I need to know something from some experts I guess.. I'm sure I'm not the only one who feels/felt like I do right now yeah? Uhm... I guess I might help you with some details so your answer may be easier to write! ( And also, if you want to say something else which is not related to PHP or C++, you can do that, I've just got to the conclusion that C++ and PHP are the ones that are worth it but yeah. C# I've discarded due to some stuff I read which says in future the projects I'd start now could just be useless and stuff like that.. ) Ok well : I'm 18 years old, and I program as hobby right now, but I do hope to go to a programming college in future. ( That would be in 2 years ). Hmm, I like programming games, and I'm mostly bothered by the fact "this language could be useless to what I need to do" ( I don't know how to explain this feeling! ) I don't know which other details I could add... I hope you guys can help me choose my path, this is really stressing me I'm wasting my time not doing anything right now because I don't know which language to use..! Thanks!

• How do you stay in touch with a programming language?

  - by Abijeet Patro

  I'll be starting work for the first time in the IT Industry on the 18th of this month. I'll be working mostly with Microsoft technologies such as C#.NET and MS Dynamic CRM. I spent the last year working with C++. Developing small applications to automate taks and organize my notes. During this time I have developed a good basic understanding of the language. My question is how do you guys stay in touch with a programming language that you love when you need to use something else at the office?

• Which language to dive into after having mastered python? [closed]

  - by larsvegas

  To put it in a nutshell: which programming language would you advice to go at next after having mastered python? I do love python (after having done some rather simple scripting in Perl for a couple of years) for it's clearness and straightforwardness. Of course there is still room for improvement and topics I haven't touched yet. Still: I feel quite confident about my skills by now but want to keep learning. I thought it might be helpful to dive into another language to learn about differences, advantages and disadvantages of one over the other etc.

  - by Azcordelia

  i just bought the Corona SDK course on Udemy, and now i need to learn Lua in order to use it. However i've never fully learned a programming language. I know a bit of Ruby, and some C++, will Lua be hard for me to learn? And is it a robust/powerful language? Thanks, but also how hard is it to use Corona SDK, i downloaded it and Sublime Test Editor 2, and so far installed the plugin for Sublime, but am juts confused.. :?

• Ruby on Rails - pass variable to nested form

  - by Krule

  I am trying to build a multilingual site using Rails, but I can't figure out how to pass variable to nested form. Right now I am creating nested form like this. @languages.each do @article.article_locale.build(:language_id => language.id) end But i would like to pass value of language to it so i can distinguish fields. Something like this. @languages.each do |language| @language = language @article.article_locale.build(:language_id => language.id) end However, I always end up with language of the last loop iteration. Any way to pass this variable? -- edit -- In the end, since I've got no answer I have solved this problem so it, at least, works as it should. Following code is my partial solution. In model: def self.languages Language.all end def self.language_name language = [] self.languages.each_with_index do |lang, i| language[i] = lang.longname end return language end In Controller: def new @article = Article.new Article.languages.each do |language| @article.article_locale.build(:language_id => language.id) end end In HAML View: -count = 0 -f.fields_for :article_locale do |al| %h3= Article.language_name[count] -count+=1 -field_set_tag do %p =al.label :name, t(:name) =al.text_field :name %p =al.label :description, t(:description) =al.text_area :description =al.hidden_field :language_id It's not the most elegant solution I suppose, but it works. I would really love if I could get rid of counter in view for instance.

• Would the world be a better place if there were only one programming language?

  - by Simon

  Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

• Why learn Perl, Python, Ruby if the company is using C++, C# or Java as the application language?

  - by szabgab

  I wonder why would a C++, C#, Java developer want to learn a dynamic language? Assuming the company won't switch its main development language from C++/C#/Java to a dynamic one what use is there for a dynamic language? What helper tasks can be done by the dynamic languages faster or better after only a few days of learning than with the static language that you have been using for several years? Update After seeing the first few responses it is clear that there two issues. My main interest would be something that is justifiable to the employer as an expense. That is, I am looking for justifications for the employer to finance the learning of a dynamic language. Aside from the obvious that the employee will have broader view, the employers are usually looking for some "real" benefit.

• Why were namespaces removed from ECMAScript consideration?

  - by Bob

  Namespaces were once a consideration for ECMAScript (the old ECMAScript 4) but were taken out. As Brendan Eich says in this message: One of the use-cases for namespaces in ES4 was early binding (use namespace intrinsic), both for performance and for programmer comprehension -- no chance of runtime name binding disagreeing with any earlier binding. But early binding in any dynamic code loading scenario like the web requires a prioritization or reservation mechanism to avoid early versus late binding conflicts. Plus, as some JS implementors have noted with concern, multiple open namespaces impose runtime cost unless an implementation works significantly harder. For these reasons, namespaces and early binding (like packages before them, this past April) must go. But I'm not sure I understand all of that. What exactly is a prioritization or reservation mechanism and why would either of those be needed? Also, must early binding and namespaces go hand-in-hand? For some reason I can't wrap my head around the issues involved. Can anyone attempt a more fleshed out explanation? Also, why would namespaces impose runtime costs? In my mind I can't help but see little difference in concept between a namespace and a function using closures. For instance, Yahoo and Google both have YAHOO and google objects that "act like" namespaces in that they contain all of their public and private variables, functions, and objects within a single access point. So why, then, would a namespace be so significantly different in implementation? Maybe I just have a misconception as to what a namespace is exactly.

• Objective-C: how to prevent abstraction leaks

  - by iter

  I gather that in Objective-C I must declare instance variables as part of the interface of my class even if these variables are implementation details and have private access. In "subjective" C, I can declare a variable in my .c file and it is not visible outside of that compilation unit. I can declare it in the corresponding .h file, and then anyone who links in that compilation unit can see the variable. I wonder if there is an equivalent choice in Objective-C, or if I must indeed declare every ivar in the .h for my class. Ari.

• Hashing words to numbers with respect to definition

  - by thornate

  As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

• Interface member name conflicts in ActionScript 3

  - by Aaron

  I am trying to create an ActionScript 3 class that implements two interfaces. The interfaces contain member functions with different signatures but the same name: public interface IFoo { function doStuff(input:int):void; } public interface IBar { function doStuff(input1:String, input2:Number):void; } public class FooBar implements IFoo, IBar { // ??? } In C# this problem can be solved with explicit interface implementations, but as far as I can tell ActionScript does not have that feature. Is there any way to create a class that implements both interfaces?

• Sentiment analysis for twitter in python

  - by Ran

  I'm looking for an open source implementation, preferably in python, of Textual Sentiment Analysis (http://en.wikipedia.org/wiki/Sentiment_analysis). Is anyone familiar with such open source implementation I can use? I'm writing an application that searches twitter for some search term, say "youtube", and counts "happy" tweets vs. "sad" tweets. I'm using Google's appengine, so it's in python. I'd like to be able to classify the returned search results from twitter and I'd like to do that in python. I haven't been able to find such sentiment analyzer so far, specifically not in python. Are you familiar with such open source implementation I can use? Preferably this is already in python, but if not, hopefully I can translate it to python. Note, the texts I'm analyzing are VERY short, they are tweets. So ideally, this classifier is optimized for such short texts. BTW, twitter does support the ":)" and ":(" operators in search, which aim to do just this, but unfortunately, the classification provided by them isn't that great, so I figured I might give this a try myself. Thanks! BTW, an early demo is here and the code I have so far is here and I'd love to opensource it with any interested developer.

• Python equivalent of IDL's stop and .reset

  - by Jamie

  Hi there, I'm relatively new to python but have a bit of experience using IDL. I was wondering if anyone knows if there are equivalent commands in python for IDL's stop and .reset commands. If I'm running some IDL script I wrote that I put a stop command in, essentially what it does is stop the script there and give me access to the command line in the middle of the script. So I have access to all the functions and variables that I defined before the stop command, which I find really useful for debugging. The .reset command I find extremely useful too. What it does is reset the the IDL environment (clears all variables, functions, etc.). It's as if I closed that session and opened a new one, but without having to exit and restart IDL. I find that if I'm trying to debug a script I wrote it's useful sometimes to start from scratch and not have to reset IDL (or python now). It would be useful also in python to be able to un-import any modules I had previously imported. Any help with these issues would be greatly appreciated. Cheers Related Python Drop into REPL Is it possible to go into ipython from code?

• What is the python "with" statement designed for?

  - by fmark

  I came across the Python with statement for the first time today. I've been using Python lightly for several months and didn't even of its existence! Given its somewhat obscure status, I thought it would be worth asking: What is the Python with statement designed to be used for? What do you use it for? Are their any gotchas I need to be aware of, or common anti-patterns associated with its use?
