  • What language, or language feature, do you wish made it to the mainstream?

    - by Macneil
    Some languages in the past have been influential without ever reaching wide adoption. For example, many languages owe much to the design of Algol 68, even though few compilers were ever written for it. The Dylan language was killed by Apple but had a clean and interesting design. What other programming languages had cool ideas but-- for whatever reasons-- didn't make it to the mainstream? Is there an interesting language feature that you wish your main language had? Is there a feature ahead of its time that we'll soon see used?

  • What percentage of revenue would be fair for app stores to take? [closed]

    - by Tyler Collier
    Apple takes 30% of revenue from app sales on the iPhone app store. Now Apple does the same with the Mac app store. Google also takes a 30% cut in the Android Market. These seem pretty steep. What percentage do you think would be fair and good for both you as a developer/vendor and Apple/Google? What's a happier middle ground? 20%? If the answer you give is less than 30% but you are selling apps in the app store or android market, please explain why you are willing to, and what benefits Apple and Google would see from reducing their cuts.

  • When modeling a virtual circuit board, what is the best design pattern to check for cycles?

    - by Wallace Brown
    To make it simple assume you have only AND and OR gates. Each has two inputs and one output. The output of two inputs can be used as an input for the next gate For example: A AND B - E C AND D - F E OR F - G Assuming an arbitrary number of gates, we want to check if the circuit ever connects back into itself at an earlier state? For example: E AND F - A This should be illegal since it creates an endless cycle. What design pattern would best be able to check for these cycles?

  • Multi-lingual error messages and error numbers

    - by Jon Hopkins
    So we're looking at the possibility of porting our software to support multiple languages and one of the areas we're going to have to deal with is error messages and other notifications. These obviously have to be reported to the users in their own language. Our team (largely) only speak English and even if we were all multi-lingual we're looking at selling to a wide range of countries and could never expect to have a reasonable number of people speaking all languages (we're a small company). The obvious way to get round the language issue when errors or other messages we may get asked about which are being reported is error numbers which would be consistent across language. While these are going to exist in the backend (if only as key on the error message), I'd really rather not throw them at users if we don't have to but I don't have any other solution. Anyone have any useful suggestions for alternatives?

  • What to watch out for when writing code at an Interview?

    - by Philip
    Hi, I have read that at a lot of companies you have to write code at an interview. On the one hand I see that it makes sense to ask for a work sample. On the other hand: What kind of code do you expect to be written in 5 minutes? And what if they tell me "Write an algorithm that does this and that" but I cannot think of a smart solution or even write code that doesn't semantically work? I am particularly interested in that question because I do not have that much commercial programming experience, 2 years part-time, one year full-time. (But I am interested in programming languages since nearly 15 years though usually I was more concentrated in playing with the language rather than writing large applications...) And actually I consider my debugging and problem solving skills much better than my coding skills. I sometimes see myself not writing the most beautiful code when looking back, but on the other hand I often come up with solutions for hard problems. And I think I am very good at optimizing, fixing, restructuring existing code, but I have problems with writing new applications from scratch. The software design sucks... ;-) Therefore I don't feel comfortable when thinking about this code writing situation at an interview... So what do the interviewers expect? What kind of information about my code writing are they interested in? Philip

  • Is there a LOGO interpreter that actually has a turtle?

    - by Tim Post
    This is not a repeat of the now infamous "How do I move the turtle in LOGO?" Recently, I had the following conversation with my five year old daughter: Daughter: Daddy, do you write programs? Me: Yes! Daughter: Daddy, what's a program? Me: A program is a set of instructions that a computer follows. Daughter: Daddy, can I write a program too? Me: Sure! This got me scrambling to think of a very basic language that a five year old could get some satisfaction from mastering rather quickly. I'm ashamed to admit that the first thing that came to mind was this: 10 INPUT "Tell me a secret" A$ 20 PRINT "Wow really? :" A$ 30 GOTO 10 That isn't going to hold a five year old's attention for very long and it requires too much of a lecture. However, moving a turtle around and drawing neat pictures might just work. Sadly, my search for a LOGO interpreter yielded noting but ad ridden sites, flight simulators and a whole bunch of other stuff that I really don't want. I'm hoping to find a cross platform (Java / Python) LOGO interpreter (dare I call it simulator?) with the following features: Can save / replay commands (stored programs) Has an actual turtle Sound effects are a plus Have you stumbled across something like this, if so, can you provide a link? I hate to ask a 'shopping' sort of question, but it seemed much better than "Is LOGO appropriate for a five year old?"

  • Which programming language for text editing?

    - by Ali
    I need a programming language for text editing and processing (replace, formatting, regex, string comparison, word processing, text analysis, etc). Which programming language is more powerful and has more functions for this purpose? Since I work PHP for my web projects, I currently use PHP; but the fact is that PHP is a scripting language for web applications, my current project is offline. I am curious if other programming languages such as Perl, Python, C, C++, Java, etc have more functionality for this purpose, and worth of shifting the project?

  • Using branchs for a mini project or module of project: Good practice?

    - by TheLQ
    In my repo I have 3 closely related mini projects: 1 server and 2 clients. They are all quite small (<3 files each). Since they are so small and so closely related I just dropped them in folders in one single repo. However now that I know I can't clone a single directory in my VCS of choice (Mercurial), I'm considering splitting them up. However I'm confused about general best practice: Is it okay to put different small projects in different branches, or should they all go in different repos? I'm currently leaning towards branching since I can't easily splice out the file history of the different projects but then your using a feature in a way it wasn't meant to be used.

  • Leadership does not see value in standard process for machine configuration and new developer orientation

    - by opensourcechris
    About 3 months ago our lead web developer and designer(same person) left the company, greener pastures was the reason for leaving. Good for them I say. My problem is that his department was completely undocumented. Things have been tough since the lead left, there is a lot of knowledge both theoretical knowledge we use to quote new projects and technical/implementation knowledge of our existing products that we have lost as a result of his departure. My normal role is as a product manager (for our products themselves) and as a business analyst for some of our project based consulting work. I've taught myself to code over the past year and in an effort to continue moving forward I've taken on the task of setting my laptop up as a development machine with hopes of implementing some of the easier feature requests and fixing some of the no brainer bugs that get submitted into our ticketing system. But, no one knows how to take a fresh Windows machine and configure it to work seamlessly with our production apps. I have requested my boss, who is still in contact with the developer who left, ask them to document and create a process to onboard a new developer, software installation, required packages, process to deploy to the productions application servers, etc. None of this exists, and I'm spinning my wheels trying to get my computer working as a functional development machine. But she does not seem to understand the need for such a process to exist. Apparently the new developer who replaced the one who left has been using a machine that was pre-configured for our environment, so even the new developer could not set up a new machine if we added another developer. My question is two part: Am I wrong in assuming a process to on-board and configure a new computer to be part of our development eco-system should exist? Am I being a whinny baby and should I figure the process out and create a document on my own?

  • Programming by dictation?

    - by Andrew M
    ie. you speak out the code, and someone else across the room types it in Anyone tried this? Obviously the person taking the dictation would need to be a coder too, so you didn't have to explain everything and go into tedious detail (not 'open bracket, new line...' but more like 'create a new class called myParser that takes three arguments, first one is...'). I thought of it because sometimes I'm too easily distracted at my computer. Surrounded by buttons, instant gratification a click away, the world at my fingertips. To get stuff done, I want to get away, write my code on paper. But that would mean losing access to necessary resources, and necessitate tedious typing-up later on. The solution? Dictate. Pros: no chance to check reddit, stackexchange, gmail, etc. code while you pace the room, lie down, play billiards, whatever train your brain to think more abstractedly (have to visualize things if you can't just see the screen) skip the tedious details (closing brackets etc.) the typist gets to shadow a more experienced programmer and learn how they work the typist can provide assistance/suggestions external pressure of typist expecting instructions, urging you to stay focussed Cons might be too hard might not work any better rather inefficient use of assisting programmer need to find/pay someone to do this

  • How do you play or record audio (to .WAV) on Linux in C++? [closed]

    - by Jacky Alcine
    Hello, I've been looking for a way to play and record audio on a Linux (preferably Ubuntu) system. I'm currently working on a front-end to a voice recognition toolkit that'll automate a few steps required to adapt a voice model for PocketSphinx and Julius. Suggestions of alternative means of audio input/output are welcome, as well as a fix to the bug shown below. Here is the current code I've used so far to play a .WAV file: void Engine::sayText ( const string OutputText ) { string audioUri = "temp.wav"; string requestUri = this->getRequestUri( OPENMARY_PROCESS , OutputText.c_str( ) ); int error , audioStream; pa_simple *pulseConnection; pa_sample_spec simpleSpecs; simpleSpecs.format = PA_SAMPLE_S16LE; simpleSpecs.rate = 44100; simpleSpecs.channels = 2; eprintf( E_MESSAGE , "Generating audio for '%s' from '%s'..." , OutputText.c_str( ) , requestUri.c_str( ) ); FILE* audio = this->getHttpFile( requestUri , audioUri ); fclose(audio); eprintf( E_MESSAGE , "Generated audio."); if ( ( audioStream = open( audioUri.c_str( ) , O_RDONLY ) ) < 0 ) { fprintf( stderr , __FILE__": open() failed: %s\n" , strerror( errno ) ); goto finish; } if ( dup2( audioStream , STDIN_FILENO ) < 0 ) { fprintf( stderr , __FILE__": dup2() failed: %s\n" , strerror( errno ) ); goto finish; } close( audioStream ); pulseConnection = pa_simple_new( NULL , "AudioPush" , PA_STREAM_PLAYBACK , NULL , "openMary C++" , &simpleSpecs , NULL , NULL , &error ); for (int i = 0;;i++ ) { const int bufferSize = 1024; uint8_t audioBuffer[bufferSize]; ssize_t r; eprintf( E_MESSAGE , "Buffering %d..",i); /* Read some data ... */ if ( ( r = read( STDIN_FILENO , audioBuffer , sizeof (audioBuffer ) ) ) <= 0 ) { if ( r == 0 ) /* EOF */ break; eprintf( E_ERROR , __FILE__": read() failed: %s\n" , strerror( errno ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } /* ... and play it */ if ( pa_simple_write( pulseConnection , audioBuffer , ( size_t ) r , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_write() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } usleep(2); } /* Make sure that every single sample was played */ if ( pa_simple_drain( pulseConnection , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_drain() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } } NOTE: If you want the rest of the code to this file, you can download it here directly from Launchpad.

  • Can't I just use all static methods?

    - by Reddy S R
    What's the difference between the two UpdateSubject methods below? I felt using static methods is better if you just want to operate on the entities. In which situations should I go with non-static methods? public class Subject { public int Id {get; set;} public string Name { get; set; } public static bool UpdateSubject(Subject subject) { //Do something and return result return true; } public bool UpdateSubject() { //Do something on 'this' and return result return true; } } I know I will be getting many kicks from the community for this really annoying question but I could not stop myself asking it. Does this become impractical when dealing with inheritance?

  • Is there any reason not to go directly from client-side Javascript to a database?

    - by Chris Smith
    So, let's say I'm going to build a Stack Exchange clone and I decide to use something like CouchDB as my backend store. If I use their built-in authentication and database-level authorization, is there any reason not to allow the client-side Javascript to write directly to the publicly available CouchDB server? Since this is basically a CRUD application and the business logic consists of "Only the author can edit their post" I don't see much of a need to have a layer between the client-side stuff and the database. I would simply use validation on the CouchDB side to make sure someone isn't putting in garbage data and make sure that permissions are set properly so that users can only read their own _user data. The rendering would be done client-side by something like AngularJS. In essence you could just have a CouchDB server and a bunch of "static" pages and you're good to go. You wouldn't need any kind of server-side processing, just something that could serve up the HTML pages. Opening my database up to the world seems wrong, but in this scenario I can't think of why as long as permissions are set properly. It goes against my instinct as a web developer, but I can't think of a good reason. So, why is this a bad idea? EDIT: Looks like there is a similar discussion here: Writing Web "server less" applications EDIT: Awesome discussion so far, and I appreciate everyone's feedback! I feel like I should add a few generic assumptions instead of calling out CouchDB and AngularJS specifically. So let's assume that: The database can authenticate users directly from its hidden store All database communication would happen over SSL Data validation can (but maybe shouldn't?) be handled by the database The only authorization we care about other than admin functions is someone only being allowed to edit their own post We're perfectly fine with everyone being able to read all data (EXCEPT user records which may contain password hashes) Administrative functions would be restricted by database authorization No one can add themselves to an administrator role The database is relatively easy to scale There is little to no true business logic; this is a basic CRUD app

  • Scrum: How to work on one story at a time

    - by Juergen
    I was nominated as scrum master in a new formed scrum team. We have already done some sprints. In the beginning I tried to make my team to work on one story at a time. But it didn't work. My team had difficulties to distribute the tasks in a way that they can work simultaneously on one story. Maybe we are doing something wrong? For example: we have a story to create a new dialog. We create the following tasks: Create Model classes Read model data from database Connect model classes with view Implement dialog handling Save data on close Test Documentation Solution Description Can theses tasks be done by more than one person at a time? The tasks - more or less - build upon each other. Or do we design the tasks in a wrong way?

  • Would learning any (linguistic) language in particular further your programming career?

    - by Anonymous
    It seems apparent that English is the dominant international language for programming based on previous P.SE questions (though a highly upvoted comment correctly points out that asking a question like that on a predominantly English site will skew the results). However, is there benefit in learning a foreign language for software development? For example, do the Chinese have completely different software tools, languages, technologies, etc? How about Japanese, Russian, and other non-latin based languages? Is there an entire world of software development languages, tools and so on that only exist in these other languages? Or do people that know these languages use the tools and languages we know and love?

  • Dependency injection in constructor, method or just use a static class instead?

    - by gaetanm
    What is the best between: $dispatcher = new Dispatcher($request); $dispatcher->dispatch(); and $dispatcher = new Dispatcher(); $dispatcher->dispatch($request); or even Dispatcher::dispatch($request); Knowing that only one method of this class uses the $request instance. I naturally tend to the last solution because the class have no other states, but by I feel that it may not be the best OOP solution.

  • Question about the no-endorsment clause on the BSD license

    - by Earlz
    I'm developing a non-free library and I want to use Bcrypt.Net in it. The clause in question: Neither the name of BCrypt.Net nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission. To what extent does this mean I can't use the name of Bcrypt.Net? For instance, could I say "the only ASP.Net authentication library capable of using Bcrypt" or can I even include "supports Bcrypt for password hashing" in promotional materials? Note: I do not actually modify any of Bcrypt.Net's code

  • What are the basic features of an email module in a common web application?

    - by Coral Doe
    When developing an email module, what are the features to have in mind, besides actual email sending? I am talking about an email module that notifies users of events and periodically sends reports. The only other feature I have in mind is maintaining grey/black lists for users that do illegal operations in the system or any other things that may lead to email/domain/IP banning. Is there an etiquette for developing email modules? Are there some references of requirements for such modules?

  • Few specific questions on how games are developed

    - by russ
    When it comes to programming games from the old school sega games like sonic to indie games or angry birds or even to more advance games like Diablo, how exactly is level design done? As in, are the levels sometimes designed straight out of code in an IDE? Or do they create a visual level design editor where things can be placed at the click of a mouse button? I'm imagining old school games or very simple ones like indies are done via code, where extremely complicated ones require a visual editor. Is this correct? Also, when it comes to libraries like SDL or XNA, how often are these used rather than just utilizing OpenGL or DirectX? What about creating your own game engine vs utilizing one already made? Do most use already built engines? This question is directed toward the whole gaming spectrum of indie/big game development. Thanks.

  • Why Beta versions have so many bugs?

    - by Eugene
    When I worked in Microsoft on MSE antivirus, we had several stages of pre-release: Alpha, Beta, RC. The biggest difference between these stages were bug fixes. Each time we fixed more bugs, and usually updated some minor features. Apple works in the same way. Look here: http://www.techrepublic.com/article/pro-tip-how-to-create-a-bootable-usb-installer-for-os-x-yosemite/ They released a beta of Yosemite OS, but the beta is full of bugs. Why do these big companies work like this? Isn't it better to release a beta version that was tested very thoroughly but one that just doesn't provide all the features that the final version will provide?

  • Is code that terminates on a random condition guaranteed to terminate?

    - by Simon Campbell
    If I had a code which terminated based on if a random number generator returned a result (as follows), would it be 100% certain that the code would terminate if it was allowed to run forever. while (random(MAX_NUMBER) != 0): // random returns a random number between 0 and MAX_NUMBER print('Hello World') I am also interested in any distinctions between purely random and the deterministic random that computers generally use. Assume the seed is not able to be known in the case of the deterministic random. Naively it could be suggested that the code will exit, after all every number has some possibility and all of time for that possibility to be exercised. On the other hand it could be argued that there is the random chance it may not ever meet the exit condition-- the generator could generate 1 'randomly' until infinity. (I suppose one would question the validity of the random number generator if it was a deterministic generator returning only 1's 'randomly' though)

  • Single database, multiple system dependency

    - by davenewza
    Consider an environment where we have a single, core database, with many separate systems using this one database. This leads to all of these systems have a common dependency, which ultimately introduces coupling between them. This means that we cannot always evolve systems independently of each other. Structural changes to the database (even if only intended for one, particular system), requires a full sweep test of ALL systems, and may require that other systems be 'patched' and subsequently released. This is especially tricky when you want to have separate teams working on different projects. What is a good 'pattern' to help in avoiding such coupling? I would imagine that a database should be exclusively depended on by one system. If other systems require data for whatever reason, they should request such from an API service of some kind. A drawback of this approach which comes to mind is performance: routing data between high-throughput systems through service calls is much slower than through a database connection.

  • Which design better when use foreign key instead of a string to store a list of id

    I'm building online examination system. I have designed to table, Question and GeneralExam. The table GeneralExam contains info about the exam like name, description, duration,... Now I would like to design table GeneralQuestion, it will contain the ids of questions belongs to a general exam. Currently, I have two ideas to design GeneralQuestion table: It will have two columns: general_exam_id, question_id. It will have two columns: general_exam_id, list_question_ids (string/text). I would like to know which designing is better, or pros and cons of each designing. I'm using Postgresql database.

  • Non-zero exit status for clean exit

    - by trinithis
    Is it acceptable to return a non-zero exit code if the program in question ran properly? For example, say I have a simple program that (only) does the following: Program takes N arguments. It returns an exit code of min(N, 255). Note that any N is valid for the program. A more realistic program might return different codes for successfully ran programs that signify different things. Should these programs instead write this information to a stream instead, such as to stdout?
