• rapid application developement tools for very basic GUI apps

  - by Jurij

  I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.

• Deploying Application with mvc in shared hosting server

  - by ankita-13-3

  We have created an MVC web application in asp.net 3.5, it runs absolutely fine locally but when we deploy it on godaddy hosting server (shared hosting), it shows an error which is related to trust level problem. We contacted godaddy support and they say, that we only support medium trust level application. So how to convert my application in medium trust level. Do I need to make changes to web.config file. It shows the following error : Security Exception Description: The application attempted to perform an operation not allowed by the security policy.

• NSPopupButton bound to NSArrayController not updating

  - by BuzzB

  I've got an NSPopupButton bound to an NSArrayController. (Man, that was harder than I thought it would be!) I have an NSArrayController bound to an NSMutableArray via the NSArrayController's "Controller Content" binding. The "Content" and "Content Values" bindings of the NSPopupButton are bound to my NSArrayController, and "Selected Object" is bound to a member in my app delegate. It is working as I expect. Except, when I add items to the NSMutableArray that my NSArrayController is bound to they don't appear in the popup. I kind of expected this to work automagically... with the NSArrayController observing the NSMutableArray and updating the NSPopupButton as necessary. Clearly I am missing something. [Update] Ok, clearly I am adding items to my array in a way that the array controller can't see. I finally found this... https://developer.apple.com/library/mac/documentation/cocoa/conceptual/CocoaBindings/Concepts/Troubleshooting.html But I really don't understand what it means. Does anyone know of a simple example of the proper way to dynamically added items to a bound NSMutableArray when the "adder" has no idea that there is a UI element bound to the array? Any help would be greatly appreciated.

• What is best practice (and implications) for packaging projects into JAR's?

  - by user245510

  What is considered best practice deciding how to define the set of JAR's for a project (for example a Swing GUI)? There are many possible groupings: JAR per layer (presentation, business, data) JAR per (significant?) GUI panel. For significant system, this results in a large number of JAR's, but the JAR's are (should be) more re-usable - fine-grained granularity JAR per "project" (in the sense of an IDE project); "common.jar", "resources.jar", "gui.jar", etc I am an experienced developer; I know the mechanics of creating JAR's, I'm just looking for wisdom on best-practice. Personally, I like the idea of a JAR per component (e.g. a panel), as I am mad-keen on encapsulation, and the holy-grail of re-use accross projects. I am concerned, however, that on a practical, performance level, the JVM would struggle class loading over dozens, maybe hundreds of small JAR's. Each JAR would contain; the GUI panel code, necessary resources (i.e. not centralised) so each panel can stand alone. Does anyone have wisdom to share?

• Tips on managing dependencies for a release?

  - by Andrew Murray

  Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.

• Version Control and Coding Formatting

  - by Martin Giffy D'Souza

  Hi, I'm currently part of the team implementing a new version control system (Subversion) within my organization. There's been a bit of a debate on how to handle code formatting and I'd like to get other peoples opinions and experiences on this topic. We currently have ~10 developers each using different tools (due to licensing and preference). Some of these tools have automatic code formatters and others don't. If we allow "blind" checkins the code will look drastically different each time someone does a check in. This will make things such as diffs and merges complicated. I've talked to several people and they've mentioned the following solutions: Use the same developer program with the same code formatter (not really an option due to licensing) Have a hook (either client or server side) which will automatically format the code before going into the repository Manually format the code. Regarding the 3rd point, the concept is to never auto-format the code and have some standards. Right now that seems to be what we're leaning towards. I'm a bit hesitant on that approach as it could lead to developers spending a lot of time manually formatting code. If anyone can please provide some their thoughts and experience on this that would be great. Thank you, Martin

• how to push different local git branches to heroku/master

  - by lsiden

  Heroku has a policy of ignoring all branches but 'master'. While I'm sure Heroku's designers have excellent reasons for for this policy (I'm guessing for storage and performance optimization), the consequence to me as a developer is that whatever local topic branch I may be working on, I would like an easy way to switch Heroku's master to that local topic branch and do a "git push heroku -f" to over-write master on Heroku. What I got from reading the "Pushing Refspecs" section of http://progit.org/book/ch9-5.html is git push -f heroku local-topic-branch:refs/heads/master What I'd really like is a way to set this up in the config file so that "git push heroku" always does the above, replacing local-topic-branch with the name of whatever my current branch happens to be. If anyone knows how to accomplish that, please let me know! The caveat for this, of course, is that this is only sensible if I am the only one who can push to that Heroku app/repository. A test or QA team might manage such a repository to try out different candidate branches, but they would have to coordinate so that they all agree on what branch they are pushing to it on any given day. Needless to say, it would also be a very good idea to have a separate remote repository (like Github) without this restriction for backing everything up to. I'd call that one "origin" and use "heroku" for Heroku so that "git push" always backs up everything to origin, and "git push heroku" pushes whatever branch I'm currently on to Heroku's master branch, overwriting it if necessary. Can anybody tell me if this would work? [remote "heroku"] url = [email protected]:my-app.git push = +refs/heads/*:refs/heads/master I'd like to hear from someone more experienced before I begin to experiment, although I suppose I could create a dummy app on Heroku and experiment with that. As for fetching, I don't really care if the Heroku repository is write-only. I still have a separate repository, like Github, for backup and cloning of all my work. Footnote: This question is similar to, but not quite the same as http://stackoverflow.com/questions/1489393/good-git-deployment-using-branches-strategy-with-heroku

• Users in database server or database tables

  - by Batcat

  Hi all, I came across an interesting issue about client server application design. We have this browser based management application where it has many users using the system. So obvisously within that application we have an user management module within it. I have always thought having an user table in the database to keep all the login details was good enough. However, a senior developer said user management should be done in the database server layer if not then is poorly designed. What he meant was, if a user wants to use the application then a user should be created in the user table AND in the database server as a user account as well. So if I have 50 users using my applications, then I should have 50 database server user logins. I personally think having just one user account in the database server for this database was enough. Just grant this user with the allowed privileges to operate all the necessary operation need by the application. The users that are interacting with the application should have their user accounts created and managed within the database table as they are more related to the application layer. I don't see and agree there is need to create a database server user account for every user created for the application in the user table. A single database server user should be enough to handle all the query sent by the application. Really hope to hear some suggestions / opinions and whether I'm missing something? performance or security issues? Thank you very much.

• Static variable not initialized

  - by Simon Linder

  Hi all, I've got a strange problem with a static variable that is obviously not initialized as it should be. I have a huge project that runs with Windows and Linux. As the Linux developer doesn't have this problem I would suggest that this is some kind of wired Visual Studio stuff. Header file class MyClass { // some other stuff here ... private: static AnotherClass* const Default_; }; CPP file AnotherClass* const Default_(new AnotherClass("")); MyClass(AnotherClass* const var) { assert(Default_); ... } Problem is that Default_is always NULL. I also tried a breakpoint at the initialization of that variable but I cannot catch it. There is a similar problem in another class. CPP file std::string const MyClass::MyString_ ("someText"); MyClass::MyClass() { assert(MyString_ != ""); ... } In this case MyString_is always empty. So again not initialized. Does anyone have an idea about that? Is this a Visual Studio settings problem? Cheers Simon

• How to refactor this database to allow sync. with smart clients?

  - by Anton Zvgny

  Howdy, I have inherited the following database: http://i46.tinypic.com/einvjr.png (EDIT: I cannot post images, so here goes the link) This currently runs 100% online thru an Asp.Net web app , but some employees will need to have offline access to this database to either get documents or to insert new documents for later synchronization when back to the office. What changes need to be made to this database scheme to support such scenario (sync smart clients with central web database)? Thanks! ps. I'm not an developer/dba, i'm just an mechanic engineer tasked with changing this app, so, take it easy on me :D ps1. We're using MSSQL Server for the online central database and MSSQL Compact for the smart client. ps2. the ImageGuid field of the images table is used to save the images to the file system. The web app takes the guid and create folders according to the first 3 initial letters to persist the image to the file system. ps3. The users of the smart client not always get server data first and then go modifying to sync later the changes. Most of the time they start working completely offline (with a blank local database) and later sync the data to the server. ps4. All the users of the smart client app have an account at the web app.

• Does Firefox on OS X Lion make use of Full Page Zoom for the touchpad? How to customize behavior?

  - by Steven Lu

  I really like the smooth pinch-zoom of Safari using the touchpad, but the two-finger scroll on Firefox is so much better than the scrolling performance in Safari. So I really like to use Firefox, but then I miss out on two-finger-double-tap to zoom to paragraph width, and the smooth pinch gesture zoom. What I'm wondering is if it is possible to write a Firefox Extension to improve the update rate of the full-page zoom in Firefox that is already functioning via the touchpad pinch gesture. I feel like it is specifically programmed to zoom at certain zoom levels: 100%, 120%, 150% (these are guesses of mine) but I think it would be great if I can get some more control there to make it work more like the zoom functionality in Safari. Also the two-finger-double-tap on a paragraph or element to zoom to it would be really awesome as well. https://developer.mozilla.org/en/Full_page_zoom This seems to indicate (if "full page zoom" is what I think it is) that an extension has the ability to zoom to an arbitrary scale factor, but what remains is to find out if it is possible to obtain or hook the touchpad pinch gesture. Update: I have updated the toolkit.zoomManager.zoomValues option in about:config to include more zoom levels: .3,.5,.67,.8,.9,1,1.01,1.02,1.03,1.04,1.05,1.06,1.07,1.08,1.09,1.1,1.2,1.33,1.5,1.7,2,2.4,3 Notice how I inserted a bunch of entries between 1 and 1.1. But it isn't switching between them any faster (why would it?) so it's less usable than before because of waiting for it to respond fast enough. It's clear that re-rendering the page at a different zoom level requires time and in order for the zoom to be dynamic, some kind of screen capture and scale effect must be performed (which is what Safari does). I guess such a thing is probably doable but I don't think I could pull it off. :-/

• How to add share menu item to Gallery by code

  - by Anthony

  I know how to implement this issue by Menuifest.xml, see also: Google Android Developer Group related issue But my question is how to add share menu of Gallery by java code not Menuifest.xml. My code is as below: public class MyActivity extends Activity { private static final String TAG = "MyActivity"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_SEND); intentFilter.addCategory(Intent.CATEGORY_DEFAULT); try { intentFilter.addDataType("image/*"); } catch (MalformedMimeTypeException e) { Log.e(TAG, e.toString()); } Intent x = registerReceiver(new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Log.d(TAG, "Received intent "+intent); intent.setComponent(new ComponentName(context, Uploader.class)); startActivity(intent); } }, intentFilter); if (x==null) Log.i(TAG, "failed to regist a receiver"); else Log.i(TAG, "registed a receiver successfully"); // ... But registerReceiver always return null, and there is no menu added to Gallery's Share. Thank you. Anthony Xu

• How do you query namespaces with PHP/XPath/DOM

  - by Alsbury

  I am trying to query an XML document that uses namespaces. I have had success with xpath without namespaces, but no results with namespaces. This is a basic example of what I was trying. I have condensed it slightly, so there may be small issues in my sample that may detract from my actual problem. Sample XML: <?xml version="1.0"?> <sf:page> <sf:section> <sf:layout> <sf:p>My Content</sf:p> </sf:layout> </sf:section> </sf:page> Sample PHP Code: <?php $path = "index.xml"; $content = file_get_contents($path); $dom = new DOMDocument($content); $xpath = new DOMXPath($dom); $xpath->registerNamespace('sf', "http://developer.apple.com/namespaces/sf"); $p = $xpath->query("//sf:p", $dom); My result is that "p" is a "DOMNodeList Object ( )" and it's length is 0. Any help would be appreciated.

• pass objective c object and primitive type into a void *

  - by user674669

  I want to pass 2 variables: UIImage * img int i into another method that only takes a (void *) I tried making a C struct containing both img and i struct MyStruct { UIImage *img; int i; } but xcode gives me an error saying "ARC forbids Objective-C objects in structs or unions" The next thing I tried is to write an objective-c class MyStruct2 containing img and i, alloc-initing an instance of it and typecasting it as (__bridge void*) before passing it to the method. Seems little involved for my use case. Seems like there should be a better way. What's the simplest way to achieve this? Thank you. Edit based on comments: I have to use void * as it is required by the UIView API. I created a selector as mentioned by UIVIew API + (void)setAnimationDidStopSelector:(SEL)selector Please see documentation for setAnimationDidStopSelector at http://developer.apple.com/library/ios/#documentation/uikit/reference/UIView_Class/UIView/UIView.html . It says ... The selector should be of the form: - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context I want to pass both img and i into the (void *)context argument.

• How do I use Perl's WWW::Facebook::API to publish to a user's newsfeed?

  - by Russell C.

  We use Facebook Connect on our site in conjunction with the WWW::Facebook::API CPAN module to publish to our users newsfeed when requested by the user. So far we've been able to successfully update the user's status using the following code: use WWW::Facebook::API; my $facebook = WWW::Facebook::API->new( desktop => 0, api_key => $fb_api_key, secret => $fb_secret, session_key => $query->cookie($fb_api_key.'_session_key'), session_expires => $query->cookie($fb_api_key.'_expires'), session_uid => $query->cookie($fb_api_key.'_user') ); my $response = $facebook->stream->publish( message => qq|Test status message|, ); However, when we try to update the code above so we can publish newsfeed stories that include attachments and action links as specified in the Facebook API documentation for Stream.Publish, we have tried about 100 different ways without any success. According to the CPAN documentation all we should have to do is update our code to something like the following and pass the attachments & action links appropriately which doesn't seem to work: my $response = $facebook->stream->publish( message => qq|Test status message|, attachment => $json, action_links => [@links], ); For example, we are passing the above arguments as follows: $json = qq|{ 'name': 'i\'m bursting with joy', 'href': ' http://bit.ly/187gO1', 'caption': '{*actor*} rated the lolcat 5 stars', 'description': 'a funny looking cat', 'properties': { 'category': { 'text': 'humor', 'href': 'http://bit.ly/KYbaN'}, 'ratings': '5 stars' }, 'media': [{ 'type': 'image', 'src': 'http://icanhascheezburger.files.wordpress.com/2009/03/funny-pictures-your-cat-is-bursting-with-joy1.jpg', 'href': 'http://bit.ly/187gO1'}] }|; @links = ["{'text':'Link 1', 'href':'http://www.link1.com'}","{'text':'Link 2', 'href':'http://www.link2.com'}"]; The above, nor any of the other representations we tried seem to work. I'm hoping some other perl developer out there has this working and can explain how to create the attachment and action_links variables appropriately in Perl for posting to the Facebook news feed through WWW::Facebook::API. Thanks in advance for your help!

• Explaining to boss why we need to avoid horizontal scroll

  - by Bradley Herman

  I need help explaining to my boss why her design is poor on a clients website. She has no knowledge of web and it can be difficult as a web developer working with a woman who is a graphic designer (not even a web designer really). On a current site she has designed, an image bar "needs" to be like 1200px according to her, though it isn't necessary with the content. I'll show a quick sketch to illustrate what's going on: http://imgur.com/MNGOT.jpg As you see, the banner spills out past the 960px of the content and as wide as 1200px. This creates a horizontal scroll when all the content is viewable within the 960px wide viewport. I need to make this an img and not a css background because it's a jquery slideshow that fades from image to image. I think this is a big problem because a lot of people are going to get a horizontal scroll bar imposed in their browser when they're still able to see all the relevant content. How do I help her explain it. She thinks no one will notice and it'll be fine, I think it's very bad practice and confusing to the end user. Any help?

• Handling incremental Data Modeling Changes in Functional Programming

  - by Adam Gent

  Most of the problems I have to solve in my job as a developer have to do with data modeling. For example in a OOP Web Application world I often have to change the data properties that are in a object to meet new requirements. If I'm lucky I don't even need to programmatically add new "behavior" code (functions,methods). Instead I can declarative add validation and even UI options by annotating the property (Java). In Functional Programming it seems that adding new data properties requires lots of code changes because of pattern matching and data constructors (Haskell, ML). How do I minimize this problem? This seems to be a recognized problem as Xavier Leroy states nicely on page 24 of "Objects and Classes vs. Modules" - To summarize for those that don't have a PostScript viewer it basically says FP languages are better than OOP languages for adding new behavior over data objects but OOP languages are better for adding new data objects/properties. Are there any design pattern used in FP languages to help mitigate this problem? I have read Phillip Wadler's recommendation of using Monads to help this modularity problem but I'm not sure I understand how?

• Career Plan: The one year plan. The three year plan.

  - by drelihan

  Hi Folks, I work as a developer however I only recently began developing full time having worked for 5 years in various roles. When it comes to career planning I think I pretty much agree with The Journeyman to Craftsman model coined in The Pragmatic Probrammer and used by Bob Martin. I see myself as a journeyman and I won't call myself a "good" (for want of a better word) until I re-evaluate my skills in 5 years time. However, as part of our careers we are encouraged to make one and three year plan with specific goals that we should hit. Unfortunately, my goal is this: Write clean code that solves a problem and is easy to maintain. From a technology point of view I want to know C++ and .net programming inside out(C#, WCF etc..) But that's it. That's my plan. Is this enough? So although there's a great discussion on what people should do with their career: http://stackoverflow.com/questions/11313/career-planning-any-tips My question is this: What's your one year plan? What's your three year plan? And am I being naive with my career? Thanks,

• Usage of static analysis tools - with Clear Case/Quest

  - by boyd4715

  We are in the process of defining our software development process and wanted to get some feed back from the group about this topic. Our team is spread out - US, Canada and India - and I would like to put into place some simple standard rules that all teams will apply to their code. We make use of Clear Case/Quest and RAD I have been looking at PMD, CPP, checkstyle and FindBugs as a start. My thought is to just put these into ANT and have the developers run these manually. I realize doing this you have to have some trust in that each developer will do this. The other thought is to add in some builders in to the IDE which would run a subset of the rules (keep the build process light) and then add another set (heavy) when they check in the code. Some other ideals is to make use of something like Cruse Control and have it set up to run these static analysis tools along with the unit test when ever Clear Case/Quest is idle. Wondering if others have done this and if it was successfully or can provide lessons learned.

• Android: Is it possible to have multiple styles inside a TextView?

  - by Legend

  I was wondering if its possible to set multiple styles for different pieces of text inside a TextView. For instance, I am setting the text as follows: descbox.setText(line1 + "\n" + line2 + "\n" + word1 + "\t" + word2 + "\t" + word3); Now, is it possible to have a different style for each text element? I mean bold for line1, normal for word1 and so on... I found this http://developer.android.com/guide/appendix/faq/commontasks.html#selectingtext: // Get our EditText object. EditText vw = (EditText)findViewById(R.id.text); // Set the EditText's text. vw.setText("Italic, highlighted, bold."); // If this were just a TextView, we could do: // vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE); // to force it to use Spannable storage so styles can be attached. // Or we could specify that in the XML. // Get the EditText's internal text storage Spannable str = vw.getText(); // Create our span sections, and assign a format to each. str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); str.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); str.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 21, str.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); But it uses position numbers inside the text. Is there a cleaner way to do this?

• Parse XML function names and call within whole assembly

  - by Matt Clarkson

  Hello all, I have written an application that unit tests our hardware via a internet browser. I have command classes in the assembly that are a wrapper around individual web browser actions such as ticking a checkbox, selecting from a dropdown box as such: BasicConfigurationCommands EventConfigurationCommands StabilizationCommands and a set of test classes, that use the command classes to perform scripted tests: ConfigurationTests StabilizationTests These are then invoked via the GUI to run prescripted tests by our QA team. However, as the firmware is changed quite quickly between the releases it would be great if a developer could write an XML file that could invoke either the tests or the commands: <?xml version="1.0" encoding="UTF-8" ?> <testsuite> <StabilizationTests> <StressTest repetition="10" /> </StabilizationTests> <BasicConfigurationCommands> <SelectConfig number="2" /> <ChangeConfigProperties name="Weeeeee" timeOut="15000" delay="1000"/> <ApplyConfig /> </BasicConfigurationCommands> </testsuite> I have been looking at the System.Reflection class and have seen examples using GetMethod and then Invoke. This requires me to create the class object at compile time and I would like to do all of this at runtime. I would need to scan the whole assembly for the class name and then scan for the method within the class. This seems a large solution, so any information pointing me (and future readers of this post) towards an answer would be great! Thanks for reading, Matt

The psycopg2 documentation was not helpful.

• What is your preferred tool stack for PHP development in the Windows Environment?

  - by Tim Visher

  I have been developing basic web sites for awhile now with some PHP thrown in for getting dynamic stuff done. However, I recently decided that it was time I got my hands a little dirtier so I wanted to start to play with the underpinnings of Wordpress and other such apps. I work on a Mac at home and have been using Coda for most of my editing needs and I love it. Also, to manage the services stack I use MAMP at home. However, I've begun to realize that for heavy PHP and Web work (AJAX, etc.), more is needed. I'm very interested to hear the kinds of tools more experienced web developers use on a day to day basis to manage the entire work flow. I found this article over on developer tutorials and decided to go with XAMPP (for the moment) for managing the services. However, IDE, Source Control, Debugger, etc. are all up for grabs. Anyway, your thoughts are much appreciated. And, if at all possible, try to describe your entire stack with what each tool fulfills for your development process.

• Code Own Socket Server or Use Red5/ElectroServer on Amazon EC2?

  - by Travis

  I've been thinking for a long time about working on a multiplayer game in Flash. I need updates frequently enough that ajax requests won't work so I need to use a socket server. The system will eventually have enough objects/players that I would consider it an MMO. I would like to set up a scalable system on Amazon's EC2. (Which probably effects my choice of server) This architecture would hopefully allow the game to grow without many changes over time. (Using a domain decomposition technique or something similar) Heres my internal debate: Should I a. Code my own socket server in C++ or Java? b. Use the free and open source Red5 socket server for Flash? or c. Pay the licensing fees and go for Electroserver? I consider myself a decent developer, but am at an impasse as to what road to go down. I'm not sure if I, could develop/would need, the features of one of the prepackaged socket servers. I'm also not sure if the prepackaged servers would work well in an Amazon EC2 environment and take full advantage of its features. Any help or guidance would be greatly appreciated.
