• Requiring multithreading/concurrency for implementation of scripting language

  - by Ricky Stewart

  Here's the deal: I'm looking at designing my own scripting/interpreted language for fun. I'm only in the planning stages right now; I want to make sure I have a very strong hold on exactly how I will implement everything before I start coding. What I'm currently struggling with is concurrency. It seems to me like an easy way to avoid the unpredictable performance that comes with garbage collection would be to put the garbage collector in its own thread, and have it run concurrently with the interpreter itself. (To be clear, I don't plan to allow the scripts to be multithreaded themselves; I would simply put a garbage collector to work in a different thread than the interpreter.) This doesn't seem to be a common strategy for many popular scripting languages, probably for portability reasons; I would probably write the interpreter in the UNIX/POSIX threading framework initially and then port it to other platforms (Windows, etc.) if need be. Does anyone have any thoughts in this issue? Would whatever gains I receive by exploiting concurrency be nullified by the portability issues that will inevitably arise? (On that note, am I really correct in my assumption that I would experience great performance gains with a concurrent garbage collector?) Should I move forward with this strategy or step away from it?

• What kinds of demos are good to make for a software engineer job

  - by user23012

  I have created my cv site and sent out my demos for a while now, but most of my demos are either from my course or games related since my course was a games programming course, I was wondering what kind of demos are good to show off my skills in programming in general. These are what i already have Pennies:just a simple game first coursework i did. Compiler:coursework for compiler writing module Pongout: basic a pong game in 68k using colour detection Snake: snake in 68k same thing as the pong Game Cube Maze: gamecube work BeatmyBot: basic Ai Basic plat-former game: 2d game with different types of collision Turing Lambda Simulation: my dissertation Turing machine simulated in Miranda. alpha and Beta reduction,and SKI calculus simulated in the Turing machine. What I am asking here is what kind of demos are good to add or have, i have been looking and have hit a tough spot I cant think of anything to make more than games. so for a general graduate software engineer what types would be good examples? EDIT: since responding to the comments bellow well for what languages well my main one would be C++, followed by Java, Erlang and abit of Haskell

• Design of input files reading when it comes to defaults/transformations

  - by Stefano Borini

  Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

• Formal definition for term "pure OO language"?

  - by Yauhen Yakimovich

  I can't think of a better place among SO siblings to pose such a question. Originally I wanted to ask "Is python a pure OO language?" but considering troubles and some sort of discomfort people experience while trying to define the term I decided to start with obtaining a clear definition for the term itself. It would be rather fair to start with correspondence by Dr. Alan Kay, who has coined the term (note the inspiration in biological analogy to cells or other living objects). There are following ways to approach the task: Give a comparative analysis by listing programming languages that exhibits certain properties unique and sufficient to define the term (although Smalltalk and Java are passing examples but IMO this way seems neither really complete or nor fruitful) Give a formal definition (or close to it, e.g. in more academic or mathematical style). Give a philosophical definition that would totally rely on semantical context of concrete language or a priori programming experience (there must be some chance of successful explanation by the community). My current version: "If a certain programing (formal) language that can (grammatically) differentiate between operations and operands as well as infer about the type of each operand whether this type is an object (in sense of OOP) or not then we call such a language an OO-language as long as there is at least one type in this language which is an object. Finally, if all types of the language are also objects we define such language to be pure OO-language." Would appreciate any possible improvement of it. As you can see I just made the definition dependent on the term "object" (often fully referenced as class of objects).

• [Dear Recruiter] I developed in Mo'Fusion

  - by refuctored

  Forward: Sometimes I really feel like technology recruiters have no experience or knowledge of the field they are recruting for.  A warning to those companies hiring technical recruiters -- ensure that the technical recruiters you hire to fill a position are actually technical.  Here's proof below, where I make up completely ridiculous technologies, but still have interest from the recruiter for an interview. Letter to me: Hello - Your name came up as a possible match for a long term contract Cold Fusion Developer role I have in Bothell, WA.  This role requires you to be onsite in Bothell, WA. This is  a tough role to fill so I was hoping you might have someone you can recommend? Unfortunately no telecommute. Thank you! Sincerly, Mindy Recruiter My response: Mindy -- Wow I'm super-excited that you took the time to contact me about this position!  Let me tell you, you won't be disappointed with my skill set! Firstly, I've been developing in ColdFusion since 1993 before it was owned by Adobe and it was operating under code name, "Hot-Jack".  Recently I started developing under the Domain-View-Driven-Domain-Model (DVDDM), integrating client-side CF on Moobuntu.  Not only do I have a boat load of ColdFusion EXP,  I also have a ton of experience in the open source communities lesser known derivative of CF, Mo'Fusion (MF).  I've also invested thousands of hours of my time learning esoteric programming languages. Look forward to working with you! George And her response: Hi George – just left you a message. Give me a call at your convenience.  The role does require someone to be onsite here.. are you able to relocate yourself? Mindy [Sigh]

• I know fundamental programming. But how do I get started in game development now?

  - by Rohan Menon

  I'm a 20 year old programming student. I know fundamental programming in BASIC, C, C++ and JAVA. What I wanted to ask is, where do I go from here? Are there any books that the community can mention that will help me develop a game or at least learn game development? I've had a lot of ideas and really want to make some sort of prototype to see if I'm suited for the industry. I really don't mind learning any new languages but I need to know what I should begin with. A good book that will help with a little more understanding as I go up will be very helpful. Maybe a tutorial to develop some basic 2D games like a side-scroller, snake or pocket tanks in an easy to understand SDK? I know that to get some credit under your belt, you need to be able to make a few games on your own. Also, what platform should I start on? The PC, iOS or Android (as an introduction) for now. I don't want to get into high level game design just yet. Just something a bit basic to help out in future development. Anything pointing me in the right direction will be really really helpful. Edit: Also, I want to say that I'm looking towards this from a game designer's point of view more than a game programmer. I want suggestions on any SDKs or easy to use programs I can use to understand game design. Then delve deeper into the programming after that. Not as employment but as developing your own games (for now).

• Monitor network connectivity in WP7 apps

  - by Daniel Moth

  Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.

• What to choose for a multilingual site with support for Markdown and commenting

  - by Kent

  I want to publish articles at a multilingual site. I want to be able to write an article in two languages and have them available on separate URLs: thesite.foo/english-breakfast thesite.com/engelsk-frukost If the users web browser is set to English I'd like to show a small notice at the top of the Swedish version with a link to the English one. The link should have an appropriate rel attribute for a translation (search for hreflang at http://diveintohtml5.org/semantics.html). There should be a way to list all articles belonging to these sets: Swedish only, English only, Swedish versions + English only, English versions + Swedish only. I'd like to publish these as four RSS-feeds. And I would like to have two versions of the main site, one in Swedish (showing Swedish versions + English only) and one in English (showing English versions). I shall be able to write the articles using Markdown, as that is the formatting language I find most convenient. There should be a way for users to comment. And some kind of way for me to protect myself against comment spam. I am leaning towards learning Drupal. I suspect I'll have to code this behavior myself as a module. To be frank I'd rather work with Java. Is Drupal the way to go? Or is there something more suitable for this project?

• Duplicate content appearing for multi lingual sites

  - by Rocky Singh

  I have a site which has a default url say "http://www.blahblah.com/" (which is default in english language). In my site there is support for multi languages. I am having few links at my home page say "English" "French" "Spanish" etc. and on clicking these links user is redirected to these links: http://www.blahblah.com/en-us/ (English) http://www.blahblah.com/fr-ca/ (French) http://www.blahblah.com/spanish-culture/ (Spanish) and based on culture in the url I am showing the content accordingly to end users in their desired language. Now, this was how my site is. The issue I am getting is with SEO. I noticed Google is considering (I checked via Google web masters) my site pages as duplicate like: 1. http://www.blahblah.com/documents/ and http://www.blahblah.com/en-us/documents/ 2. http://www.blahblah.com/news/ and http://www.blahblah.com/en-us/news and similarly all the pages are considered as a duplicate content in Google webmasters tools. I am worried of this, since I think my site is getting penalized in ranking because of this. Could you drop some idea how to overcome this situation?

• Why isn't Java used for modern web application development?

  - by Cliff

  As a professional Java programmer, I've been trying to understand - why the hate toward Java for modern web applications? I've noticed a trend that out of modern day web startups, a relatively small percentage of them appears to be using Java (compared to Java's overall popularity). When I've asked a few about this, I've typically received a response like, "I hate Java with a passion." But no one really seems to be able to give a definitive answer. I've also heard this same web startup community refer negatively to Java developers - more or less implying that they are slow, not creative, old. As a result, I've spent time working to pick up Ruby/Rails, basically to find out what I'm missing. But I can't help thinking to myself, "I could do this much faster if I were using Java," primarily due to my relative experience levels. But also because I haven't seen anything critical "missing" from Java, preventing me from building the same application. Which brings me to my question(s): Why is Java not being used in modern web applications? Is it a weakness of the language? Is it an unfair stereotype of Java because it's been around so long (it's been unfairly associated with its older technologies, and doesn't receive recognition for its "modern" capabilities)? Is the negative stereotype of Java developers too strong? (Java is just no longer "cool") Are applications written in other languages really faster to build, easier to maintain, and do they perform better? Is Java only used by big companies who are too slow to adapt to a new language?

• Is it recommended to use more than one language at a startup?

  - by GoofyBall

  I work for a mobile startup where, for historical reasons, our chosen language was C#. I was recently assigned to a small project to build a tool that would be used by us internally. When I explained my intention to use Python to build this tool I was heavily criticized for this because introducing new languages, and technologies (Debian, Apache, Python and Django) into our ecosystem would make it harder for other developers to maintain (because only two other people know more than one language besides C#). I countered that this project would take far longer to develop in C# (which I think is an inherent problem with the language/.NET framework) and that the project was small and designed to solve a very particular problem. Of course it is necessary that the ecosystem be as a homogeneous as possible but if your are developing tooling, infrastructure, and internal systems when there are better things to build them with than C# then you should consider using them. By using one language you exclude a lot of other great libraries and frameworks out there, and this case it was the difference between taking one week to build in Python as opposed to a month in C#. Do you think it is acceptable to understand and use only only one language at a startup or even a larger company? Am I perhaps being naive??

• Looking for 2D Cross platform suggestions based on requirements specified

  - by MannyG

  I am an intermediate developer with minor experience on enterprise mobile applications for iphone, android and blackberry looking to build my first ever mobile game. I did a google search for some game dev forums and this popped up so I thought I would try posting here as I lack luck elsewhere. If you have ever heard of the game for the iphone and android platform entitled avatar fight then you will have an idea of the graphic capabilities I require. Basically the battles which are automated one sprite attacking another doing cool animations but all in 2d. My buddy and I have two motivations, one is to jump into mobile Dev as my experience is limited as is his so we would like some trending knowledge (html5 would be nice to learn) . The other is to make some money on the side, don't expect much but polishing the game and putting our all will hopefully reward us a bit. We have looked into corona engine, however a lot of people are saying it is limited in the graphics department, we are open to learning new languages like lua, c++, python etc. Others we have looked at include phonegap, rhomobile, unity, and the list goes on. I really have no idea what the pros and cons of these are but for a basic battle sequence and some mini games we want to chose the right one. Some more things that we will be doing include things like card games, side scrolling flying object based games, maybe fishing stuff. We want to start small with these minigames and work our way up to the idea we would like to implement in the future. We only want to work in 2D. So with these requirements please help me chose a platform to work on (cross platform is what we are ideally leaning towards). Please feel free to throw in some pieces of advice you may have for newbie game developers like myself too. Thank you for reading!

• What web technology could I use which would support a decision tree?

  - by Rami Alhamad

  I am a big game development fan but I haven't done any commercial work in the past. I have been asked by a non-profit to look at developing a game similar to the award-winning www.playspent.org They want the following features: support 5 scenarios mobile isn't important but compatibility with older browsers would be a big bonus they want it to be visual and audible bonus is to have it easily modifiable support 4 languages I don't have much knowledge of Flash and would rather avoid using it as a solution. I started breaking down the problem into segments that I will need to examine, they are as follows: ability to read the game flow from a file that they can produce (xml, etc.) db design to store decision tree language challenge browser compatibility I am leaning towards an Google app engine/GWT solution but I am not sure what technology is best for this. I am really hoping to get your opinion/recommendation on my approach and on what technology is best. A special thanks (and beer if you live in Toronto) will be awarded to anyone who can help give me a ballpark estimate on how much such a game should go for. I know it's tough to estimate but any rough figure will help (how much would you charge for building something like playspent.org?) Thanks in advance

• Best Java Book(s) for an Experienced Developer

  - by Steven Elliott Jr

  I have been a .NET developer now for about the past 5/6 years give or take. I have never done any professional Java development and the last time I really touched it was probably back in college. I have been toying with the Scala language a little bit but nothing serious. Recently, I've been offered an opportunity to do some pretty cool work, but using Java instead of .NET. I think I can get by alright with my current skill set, meaning I already know how to program well and am familiar with languages such as C# and C++, etc. So, the syntax and all that language stuff are really not a problem. What I need is a really good reference book and a book about how to think in Java. Each language/Framework/Stack tries to address things a certain way and I'm sure Java is no different. What are some great Java books that you simply can't live without? Are there any books that talk about the most important parts of Java that must be understood before all else? As a side note, I will be doing mostly Java web development. Not really 100% on what types of stuff they are using for persistence, framework, server, etc. Thanks again for the consideration.

• Were the first assemblers written in machine code?

  - by The111

  I am reading the book The Elements of Computing Systems: Building a Modern Computer from First Principles, which contains projects encompassing the build of a computer from boolean gates all the way to high level applications (in that order). The current project I'm working on is writing an assembler using a high level language of my choice, to translate from Hack assembly code to Hack machine code (Hack is the name of the hardware platform built in the previous chapters). Although the hardware has all been built in a simulator, I have tried to pretend that I am really constructing each level using only the tools available to me at that point in the real process. That said, it got me thinking. Using a high level language to write my assembler is certainly convenient, but for the very first assembler ever written (i.e. in history), wouldn't it need to be written in machine code, since that's all that existed at the time? And a correlated question... how about today? If a brand new CPU architecture comes out, with a brand new instruction set, and a brand new assembly syntax, how would the assembler be constructed? I'm assuming you could still use an existing high level language to generate binaries for the assembler program, since if you know the syntax of both the assembly and machine languages for your new platform, then the task of writing the assembler is really just a text analysis task and is not inherently related to that platform (i.e. needing to be written in that platform's machine language)... which is the very reason I am able to "cheat" while writing my Hack assembler in 2012, and use some preexisting high level language to help me out.

• Should a Parent with Children have a DefaultChild, or should a Child have a Default property?

  - by Stijn

  Which of the following two models makes more sense? I'm leaning towards the first one because there can only be one default child. The examples are in C# but I think it can apply to other languages too. Here DefaultChild holds one of the items in Children. class Parent { int ID { get; set; } Child DefaultChild { get; set; } IEnumerable<Child> Children { get; set; } } class Child { int ID { get; set; } } Here one of the items in Children has Default set to true while the others have it set to false. class Parent { int ID { get; set; } IEnumerable<Child> Children { get; set; } } class Child { int ID { get; set; } bool Default { get; set; } } A concrete situation: a User in our system has one or more Customers attached. When logging in, if said User has a default Customer, they are immediately working under this Customer. If they don't, they have to select a Customer to work under. While logged in, they can switch between Customers.

• Creating user UI using Flixel

  - by Jamie Read

  I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

• What should I learn that I missed by not going to school?

  - by BinaryMuse

  I'm a software engineer at a local university, and I feel I'm able to competently do my job, but recently I've been interested in "filling in" the gaps in my knowledge. I suspect I would have learned some of this in school; for example, I don't have a lot of knowledge of sorting algorithms (something I feel is pretty common in college). So, what knowledge am I likely missing by not going to college that I could study on my own? Bonus points for listing resources that might put me on the right track! Some background: I've programmed in PHP, Java, and Ruby (more seriously in Java and Ruby than PHP); I have some experience with C/C++, though my workload doesn't really lend itself to those languages; I work mostly (recently) with the web, using frameworks such as CakePHP and Rails. I'm familiar with SQL (though probably not with some of the theory). Note: The university I work for has no technical classes, so taking courses on the university's dime is a great idea but not possible for me. :)

• Koans, now available in Python flavor

  - by Greg Malcolm

  Recently a Python developer friend with whom I was pair programming with suggested that I show him how to write a little Ruby. I responded by telling him to check out Ruby Koans as a starting point. However I wanted to try that in reverse at the same time with me learning some Python. I did a bit of googling, and sure enough someone had started writing some Python Koans. It just needed finishing... So, a few weeks later Python Koans is now complete and ready for action! It is available through Mercurial on Bitbucket: http://bitbucket.org/gregmalcolm/python_koans/wiki/Home It is also mirrored on Github: http://wiki.github.com/gregmalcolm/python_koans/ Converting it was fairly easy. Aside from the differing philosophical approaches behind the two languages, Ruby and Python are fairly similar. We had to come up with completely new material for a few subjects like multiple inheritance and decorators, but for most features in Ruby there is something roughly comparable in Python. I highly recommend writing tests (or koans) as a means to lean a new language or framework. I've learned a lot from doing this.

• Mobile cross-platform SDK for computationally intensive apps

  - by K.Steff

  I am aware of the PhoneGap toolkit for creating mobile applications for virtually all mobile platforms with a significant market share. However, the code in PhoneGap that is shared between the different platforms is written in JavaScript. While I like JS, I think it's hardly appropriate for computationally intensive tasks. The situation with Titanium is pretty much the same. So, is there any way that I can create a cross-platform mobile app that has the computationally intensive code shared between the platforms? Some context: Obviously, I don't want to implement the time consuming algorithm in many different languages, since this violates DRY, increases the chance for bugs slipping in at least one version and require boilerplate code to work. I've looked at Xamarin's MonoTouch and Mono for Android tools, but while they cover iOS and Android, they're not nearly as versatile for deployment as PhoneGap. On the other hand, (IMO) the statically typed nature of C# is more suited for intense computation than JS. Are there any other SDK/tools appropriate for the task that I don't know about or a point about the mentioned above that I've missed? Also, uploading data to a web service for processing is not an option, because of the traffic required.

• How to present a stable data model in a public API that allows internal data structures to be changed without breaking the public view of the data?

  - by Max Palmer

  I am in the process of developing an application that allows users to write C# scripts. These scripts allow users to call selected methods and to access and manipulate data in a document. This works well, however, in the development version, scripts access the document's (internal) data structures directly. This means that if we were to change the internal data model/structure, there is a good chance that someone's script will no longer compile. We obviously want to prevent this breaking change from happening, but still want to allow the user to write sensible C# code (whilst not restricting how we develop our internal data model as a result). We therefore need to decouple our scripting API and its data structures from our internal methods and data structures. We've a few ideas as to how we might allow the user to access a what is effectively a stable public version of the document's internal data*, but I wanted to throw the question out there to someone who might have some real experience of this problem. NB our internal document's data structure is quite complex and it could be quite difficult to wrap. We know we want to expose as little as possible in our public API, especially as once it's out there, it's out there for good. Can anyone help? How do scripting languages / APIs decouple their public API and data structures from their internal data structures? Is there no real alternative to having to write a complex interaction layer? If we need to do this, what's a good approach or pattern for wrapping complex data structures that include nested objects, including collections? I've looked at the API facade pattern, which looks like it's trying to address these kinds of issues, but are there alternatives? *One idea is to build a data facade that is kept stable across versions of our application. The facade exposes a set of facade data objects that are used in the script code. These maintain backwards compatibility and wrap access to our internal document's data model.

• Compiled code spreadsheet-like cell management? (auto-updating)

  - by proGrammar

  Okay so I am fully aware how spreadsheets manage cells, they build dependency graphs where when one cell changes it tells all the other cells that are dependent on it that it changed. So they can from there update. How they update I think involves either re-evaluating the formulas stored as strings, or re-evaluating the abstract syntax tree which I think is stored differently and might be faster. Something like that. What I'm looking to do is manage a few variables in my code so I don't have to update them in the correct way, which would be a nightmare. But I also want it much faster than spreadsheets. And since I'm not looking for any functionality as great as are in these spreadsheets, I just figured from that thought point that there has to be a way to have a very fast implementation of this functionality. Especially since I don't have to modify cells after compiling unless that would be an option. I'm very new to programming so I have no idea. One example might be to have a code-generator that generates code that does this for me. But I have no clue what the generated code would look like. Specifically, how exactly would variables inform others that they need to update, and what do those variables do to update? I'm looking for any kind of ideas. Programming is not my job but nonetheless I was hoping to have some kind of system like this that would greatly help me with some stuff. Of course I have been programming plenty lately so I can still program. I just don't have the full scope on things. I'm looking for any kind of ideas, thank you very much in advance! Also, please help me with the tags. I know C# and Java mainly and I'm hoping to implement this in either of those languages and I'm hoping this can stay in those tags. Forcing this into some kind of spreadsheet tag wouldn't be accurate.
