  • What makes a language (or feature) "hackerish"?

    - by iCanLearn
    I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

  • What are the key aspects of a strongly typed language?

    - by Chris Sutton
    What makes a language strongly typed? I'm looking for the most important aspects of a strongly typed language. Yesterday I asked if PowerShell was strongly typed, but no one could agree on the definition of "strongly-typed", so I'm looking to clarify the definition. Feel free to link to wikipedia or other sources, but don't just cut and paste for your answer.

  • Zend_Controller_Router_Route: Could not find a translator

    - by Antonio
    I am developing a multilanguage application. In the bootstrap there is the routes setup: protected function _initRoutes() { $this->bootstrap('frontController'); $router = $this->frontController->getRouter(); // PAGES ROUTE $page = new Zend_Controller_Router_Route( ':language/:ident', array( 'module' => 'core', 'controller' => 'pagine', 'action' => 'view' ), array( 'ident' => '[a-zA-Z-_0-9]{3,}', 'language' => '[a-z]{2}' ) ); $registrazione = new Zend_Controller_Router_Route( ':language/@utenti/@registrati', array( 'module' => 'core', 'controller' => 'utenti', 'action' => 'registrazione' ), array( 'language' => '[a-z]{2}' ) ); $router->addRoute('page', $page); $router->addRoute('registrazione', $registrazione); ..... } I cannot set the default translator to Zend_Controller_Router_Route (for translated segments) because i don't know the language parameter in the request object. I get the language parameter in Multilanguage Plugin during the "routeShutdown": class Activa_Controller_Plugin_Multilanguage extends Zend_Controller_Plugin_Abstract { public function routeShutdown(Zend_Controller_Request_Abstract $request) { $language = $request->getParam("language"); $locale = new Zend_Locale($language); $translate = new Zend_Translate('array', APPLICATION_PATH.'/config/lang/'.$language.'.php', $locale); Zend_Registry::set('Zend_Locale', $locale); Zend_Registry::set('Zend_Translate', $translate); Zend_Controller_Router_Route::setDefaultTranslator($translate); //////////////////////// // BUT NOW IS TOO LATE //////////////////////// } When i type the address "http://servername/it/utenti/registrati" i get the exception with the message "Could not find a translator". How can i fix it? Antonio (Italy)

  • loading data from a flat file to table using informatica, having both english and foreign language c

    - by Manish
    I am loading data from a flat file to table using informatica, the file has both english and foreign language characters like chinese, and others. The foreign language characters are not getting displayed properly after loading. How can this problem be solved ? I could solve it by using code page UTF - 16 Encoding of Unicode Platform Endian, earlier i was using different code page UTF-8.

  • How to get started with embedded systems in the airline or submarine industries?

    - by Jason
    Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!

  • How to deploy a Java Swing application with an embedded JavaDB database?

    - by Jonas
    I have implemented an Java Swing application that uses an embedded JavaDB database. The database need to be stored somewhere and the database tables need to be created at the first run. What is the preferred way to do these procedures? Should I always create the database in the local directory, and first check if the database file exist, and if it doesn't exist let the user create the tables (or at least show a message that the tables will be created). Or should I let the user choose a path? but then I have to save the path somewhere. Should I save the path with Preferences.systemRoot();, and check if that variable is set on startup? If the user choses a path and save it in the Preferences, can I get any problems with user permissions? or should it be safe wherever the user store the database? Or how do I handle this? Any other suggestions for this procedure?

  • #define vs enum in an embedded environment (How do they compile?)

    - by Alexander Kondratskiy
    This question has been done to death, and I would agree that enums are the way to go. However, I am curious as to how enums compile in the final code- #defines are just string replacements, but do enums add anything to the compiled binary? Or are they both equivalent at that stage. When writing firmware and memory is very limited, is there any advantage, no matter how small, to using #defines? Thanks! EDIT: As requested by the comment below, by embedded, I mean a digital camera. Thanks for the answers! I am all for enums!

  • How to test reliability of my own (small) embedded operating system ?

    - by TridenT
    I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

  • How many programming jobs are there that require German/French language ?

    - by HJ-INCPP
    Hello, I want to improve my chances getting a job (entry-level:programming) by learning another language. How many jobs that require exclusively French, German, English are there ? Which is better to learn (more/better jobs): French or German ? Is it worth it (or should I learn another programming language instead :D) ? Thank you. P.S I live in Romania, I (think I) know English

  • Does knowing a Natural Language well help with Programming?

    - by Earlz
    We all hear that math at least helps a little bit with programming. My question though, does English or other natural language skills help with programming? I know it has to help with technical documentation, but what about actual programming? Are certain constructs in a programming language also there in natural languages? Does knowing how to write a 20 page research paper help with writing a 20k loc programming project?

  • How can I write a "Hello World" app in assembly language?

    - by SLC
    I've often heard of applications written using the language of the gods, assembly language. I've never tried though, and I don't even have a clue how to do it. If I wanted to dabble, how would I go about doing it? I know absolutely nothing about what is required, although presumably some kind of compiler and Notepad. Just purely out of curiousity, what would I need to write a "Hello World!" application?

  • Embedded Lua on iPhone. What's new and what does it mean?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • Why are C, C++, and LISP so prevalent in embedded devices and robots?

    - by David
    It seems that the software language skills most sought for embedded devices and robots are C, C++, and LISP. Why haven't more recent languages made inroads into these applications? For example, Erlang would seem particularly well-suited to robotic applications, since it makes concurrent programming easier and allows hot swapping of code. Python would seem to be useful, if for no other reason than its support of multiple programming paradigms. I'm even surprised that Java hasn't made a foray into general robotic programming. I'm sure one argument would be, "Some newer languages are interpreted, not compiled" - implying that compiled languages are quicker and use fewer computational resources. Is this still the case, in a time when we can put a Java Virtual Machine on a cell phone or a SunSpot? (and isn't LISP interpreted anyway?)

  • 4GB limitation on these embedded/express DBs good enough? what's next if limitation is reached?

    - by edwin.nathaniel
    I'm wondering how long a (theoretically) desktop-app can consume the full 4GB limitation of these express/embedded database products (SQL-Server Express, Oracle Express, SQLite3, etc) provided that big blobs will be stored in filesystem. Also what would be your strategy when it hits the 4GB? Archive the old DB Copy 1-3 months of data to the new DB (consider this as cache strategy?) Start using the new DB from this point onward (How do you access the old data?) I understand that the answer might varies depending on how much data you stored in the table/column. But please describe based on your experience (what kind of desktop-app, write/read heavy, how long will it reach according to your guess).

  • PHP text parsing and / or make your own language?

    - by AlexanderJohannesen
    Been Googling around without finding much at all, so does anyone know of a class or library that helps you parse any sort of language, like a Domain Specific Language (I'm creating one, so I'm flexible in what the syntax and format can be) into either PHP code or some helpful struct or a class hiearchy or ... ? Anything goes at this point. :) I want to experiment with parsing text files into tokens, building up a small grammar and syntax library to express things like Business Natural Languages.

  • Embedded quicktime video pause on click how to prevent?

    - by Marek
    I embedded a quicktime video in firefox. It works, but i would like to prevent the users to stop the video by clicking on it with the left mouse button. Reading the apple documentation i didn't find any answear. I came up with a workaround, i just put an almost invisible div over the whole video. The workaround works in firefox for os X, but oddly does not for the same version of firefox in windows. I would appreciate a way, workaround or not, to achive this at least in the windows/firefox environment. Thanks!
