• WebSocket support on mobile devices

  - by Marco W.

  For an Android multiplayer game's communication between players I'm using a WebSocket server and TooTallNate's Java library on the client side to enable WebSocket support in the Android app. So just to point it out clearly, WebSocket support in mobile browsers is not important to me. Unfortunately, users report that they're experiencing problems such as connection failures or unreceived messages. Is that a general problem of WebSockets on mobile devices (blocked ports, firewalls, mobile Internet connection) or is that probably a flaw in the client side code? Do you have experience with WebSocket client libraries such as the one above? I've just discovered autobahn.ws for Android - but I don't know if it's worth switching from my current library (see above). What about WAMP? Is WebSocket technology not exactly the adequate solution so that I should use the sub-protocol (?) WAMP?

• Building html tables from query data... faster?

  - by Andrew Heath

  With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

• SQLite doesn't have booleans or date-times.

  - by DanM

  I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?

• Viewing, building & debugging Borland C++ Builder project in Visual Studio 2010

  - by grunt

  I would like to use VC2010 to handle a BCB 2006 project I have. I do not want to convert the code to VC since much UI will need to be ported. I just want to be able to view build & debug from VS IDE. Viewing: I assume once I create VS projects for the native BCB code viewing will be possible, although the UI editor will not. Building: I found the "C++ Native Multi-Targeting" option of VS, although I'm not sure on what to set the different options there to (Daffodil is mentioned as helpful although I'm not sure what the added value is over existing functionality). Debugging: not sure how to do this at all from within VS. There are some stand alone console tools that convert debug info files e.g. tds2pdb (wheres the documentation link?). If anyone has experience with such a task I would thank you for any advice.

• SQL Server indexed view matching of views with joins not working

  - by usr

  Does anyone have experience of when SQL Servr 2008 R2 is able to automatically match indexed view (also known as materialized views) that contain joins to a query? for example the view select dbo.Orders.Date, dbo.OrderDetails.ProductID from dbo.OrderDetails join dbo.Orders on dbo.OrderDetails.OrderID = dbo.Orders.ID cannot be automatically matched to the same exact query. When I select directly from this view ith (noexpand) I actually get a much faster query plan that does a scan on the clustered index of the indexed view. Can I get SQL Server to do this matching automatically? I have quite a few queries and views... I am on enterprise edition of SQL Server 2008 R2.

• What is the best logging solution for a C# .NET 3.5 project?

  - by Odd

  My team is about to start a new enterprise wide ASP.NET development project, quite possibly the largest undertaken by my department so far and the largest project that I've ever worked on. I'm looking for a good logging solution for the system. Firstly, what logging tools are currently available and widely used? Secondly, for an ASP.NET (probably MVC) enterprise applicaiton, which tool is most appropriate based on your experience? So far I've used Log4net almost exclusively for all my previous projects. It's a fantastic tool, however I would like to see if there is anything I've not used out there before I start a project of this magnitude or if there is any reason I would not want to use Log4net for a project of this size.

• An image from byte to optimized web page presentation

  - by blgnklc

  I get the data of the stored image on database as byte[] array; then I convert it to System.Drawing.Image like the code shown below; public System.Drawing.Image CreateImage(byte[] bytes) { System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(bytes); System.Drawing.Image image = System.Drawing.Image.FromStream(memoryStream); return image; } (*) On the other hand I am planning to show a list of images on asp.net pages as the client scrolls downs the page. The more user gets down and down on the page he/she does see the more photos. So it means fast page loads and rich user experience. (you may see what I mean on www.mashable.com, just take care the new loads of the photos as you scroll down.) Moreover, the returned imgae object from the method above, how can i show it in a loop dynamically using the (*) conditions above. Regards bk

• How many records can i store in a Sql server table before it's getting ugly?

  - by Michel

  Hi, i've been asked to do some performance tests for a new system. It is only just running with a few client, but as they expect to grow, these are the numbers i work with for my test: 200 clients, 4 years of data, and the data changes per.... 5 minutes. So for every 5 minutes for every client there is 1 record. That means 365*24*12 = 105.000 records per client per year, that means 80 milion records for my test. It has one FK to another table, one PK (uniqueidentifier) and one index on the clientID. Is this something SqlServer laughs about because it isn't scaring him, is this getting too much for one quad core 8 GB machine, is this on the edge, or..... Has anybody had any experience with these kind of numbers?

• Good tool to test WCF service (not SOAP/HTTP webservice)

  - by Kangkan

  I recently found SOAPUI and discovered that it is just a great tool for testing any SOAP/HTTP service. Conventionally, we have been developing our own driver to test our services (WCF based netTCP binding) so far. But with SOAPUI experience, I am really looking for some such tool that can be used with such ease with built-in facilities for load testing, functional testing etc. The other thought in my mind is that for services that I wish to deploy with netTCP can be first tested using a HTTP binding using SOAPUI. Once found suitable, the binding can be changed for the intended one. I shall like the views from all the experts here. Thanks.

• CGI, python, and setgid

  - by user331398

  I'm running a compiled python cgi script (using cxfreeze) in Apache. The script, among other things, calls os.setuid(some_uid) os.setgid(some_gid) Obviously some_uid/gid are legal and I set the sticky bit for both user and group, and verified it is indeed set. However on every call i get an error os.setgid(int(self.gid)) OSError: [Errno 1] Operation not permitted As you may notice, setuid() is successful, setgid is not. Which is very weird, at least for me, though I admit I have little experience with permissions in Linux. Any thoughts/ideas are welcome. I'm using apache 2.2.15, python 2.6.5, RHEL 5.4 (kernel 2.6.18) Thank you

• How to build a Video Broadcaster, which can handle more than 20,000 viewers

  - by Gaurav Srivastava

  I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

• Avoid hourglass mouse cursor when calling a web-service?

  - by BigMoose

  I don't know if this is a general web-services issue or just my specific scenario, which is a WPF application with a DispatcherTimer calling a web-service method. Whenever the timer is called, the mouse cursor automatically changes to an hourglass cursor. The processing of the call is very short and happens every 3 seconds, so the user experience is that every 3 seconds the mouse filckers as an hourglass for a split-second and then goes back to the normal cursor representation. How can I avoid this inconvenience? Thanks.

• Recommended Python publish/subscribe/dispatch module ?

  - by Eli Bendersky

  From PyPubSub: Pypubsub provides a simple way for your Python application to decouple its components: parts of your application can publish messages (with or without data) and other parts can subscribe/receive them. This allows message "senders" and message "listeners" to be unaware of each other: one doesn't need to import the other a sender doesn't need to know "who" gets the messages, what the listeners will do with the data, or even if any listener will get the message data. similarly, listeners don't need to worry about where messages come from. This is a great tool for implementing a Model-View-Controller architecture or any similar architecture that promotes decoupling of its components. There seem to be quite a few Python modules for publishing/subscribing floating around the web, from PyPubSub, to PyDispatcher to simple "home-cooked" classes. Can you recommend a module that works well in most cases ? Which modules have you had positive experience with ? Negative ? Thanks in advance

• Nesting maximum amount of shapes on a surface

  - by Fuu

  In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, made out of polygons and/or curved lines, and target is another polygon of given dimensions. I assume many of the current CAM suites implement this, but having no experience using them or of their internals, what kind of computational algorithm is used to find the most efficient use of space? Can someone point me to a book or other reference that discusses this topic?

• to-many Core Data fetch request behaves oddly with a new store

  - by Giao

  I have two entities, Department and Person. Department has a to-many relationship to Person. The Person entity has a hireDate property. I'm using the predicate "count(person) = 0 OR none person.hireDate %@" to find Departments without any Persons in them or Departments that haven't hired anyone since a recent date. When the app first starts up (new user experience) and Departments are inserted and no Person have been inserted, the fetch request with this predicate returns nothing. However, if I create insert a new Person entity and delete it, then save the store, the fetch request will return all the Departments. I've found a work around where, I just insert a new Person and delete it, then save the store, the fetch request as I expected it to work. I've found that inserting a new Person and deleting it without saving will not correct the problem. Is this a bug with Core Data or is this a bug with how I've designed my app?

• Adding a imageview to child elements in a expandable list query

  - by Thomas Millin

  I am looking to find out how to assign an image to a imageview in each child of an expandable list. If anyone has any information or links to find out how to do this I would be most appreciative. expListAdapter = new SimpleExpandableListAdapter( main.this, createGroupList(), R.layout.parentnode, new String[] { "day", "number" }, new int[] { R.id.TextView01, R.id.TextView02 }, createChildList(), R.layout.child_row, new String[] { "image", "childName", "date"}, new int[] { R.id.ImageView01, R.id.childname, R.id.date } ); setListAdapter( expListAdapter ); is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start. Any help would be great :D

• Accessing HttpRequest from Global.asax via a page

  - by Polymorphix

  I'm trying to get a property (ImpersonatePersonId) from a page in global.asax but get a HttpException saying 'Request is not available in this context'. I've been searching for some documentation on where in the pipeline the request is accessible, but as far as I can see all Microsoft can produce of documentation is one-liners like "PostRequestHandlerExecute: Occurs when the ASP.NET event handler finishes execution." which really doesn't give me much... I've tried placing the call in both Pre and PostRequestHandlerExceute but with the same result. I wonder if anyone with experience in this would be so kind as to tell me where the Request object is available. My code from global asax is below. ICanImpersonate page = HttpContext.Current.Handler as ICanImpersonate; ImpersonatedUser impersonatePerson = page != null ? page.ImpersonatePersonId : null; Response.Filter = new TagRewriter(Response, new TagProcessor(Context, impersonatePerson).Process); What I want to do is rewrite some HTML based on some request parameters.

• Have you ever turned-down morally questionable or unethical web work?

  - by louism

  i'm just wondering if you guys have ever had a situation where you were offered a web development project which you turned down because you felt it was unethical or morally questionable. i've only had this once. i was offered a contract to develop a website for a meat abattoir (i.e. slaughterhouse). what's the problem you may ask? i'm vegetarian. i know, it's not an egregious dilemma, but it just didn't seem right to me. i have a female graphic designer friend who declined to work on a sex toys website where she was working at the time. funny thing is, it wouldn't bother me to work on a porn site (as long as it wasn't anything shifty - e.g. dwarfs + donkeys, that sort of thing). anyone else ever had a similar experience?

• What turns away users/prospective users?

  - by Zach Johnson

  In your experience, what kinds of things have turned away users and prospective users from using your programs? Also, what kinds of things turn you away from using someone else's programs? For example, one thing that really bugs me is when someone provides free software, but requires you to enter your name and email address before you download it. Why do they need my name and email address? I just want to use the program! I understand that the developer(s) may want to get a feel for how many users they have, etc, but the extra work I have to do really makes me think twice about downloading their software, even if it does really great things.

• Looking to eventually build a smartphone app...

  - by Brian L

  Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

• How to reduce java concurrent mode failure and excessive gc

  - by jimx

  In Java, the concurrent mode failure means that the concurrent collector failed to free up enough memory space form tenured and permanent gen and has to give up and let the full stop-the-world gc kicks in. The end result could be very expensive. I understand this concept but never had a good comprehensive understanding of A) what could cause a concurrent mode failure and B) what's the solution?. This sort of unclearness leads me to write/debug code without much of hints in mind and often has to shop around those performance flags from Foo to Bar without particular reasons, just have to try. I'd like to learn from developers here how your experience is. If you had previous encountered such performance issue, what was the cause and how you addressed it? If you have coding recommendations, please don't be too general. Thanks!

• Using gmail as SMTP server in Java web app is slow

  - by Annie

  Hi, I was wondering if anyone might be able to explain to me why it's taking nearly 30 seconds each time my Java web app sends an email using Gmail's SMTP server? See the following timestamps: 13/04/2010-22:24:27:281 DEBUG test.service.impl.SynchronousEmailService - Before sending mail. 13/04/2010-22:24:52:625 DEBUG test.service.impl.SynchronousEmailService - After sending mail. I'm using spring's JavaMailSender class with the following settings: email.host=smtp.gmail.com [email protected] email.password=mypassword email.port=465 mail.smtp.auth.required=true Note that the mail is getting sent and I'm receiving it fine, there's just this delay which is resulting in a slow experience for the application user. If you know how I can diagnose the problem myself that would be good too :)

• Does Seaside scale?

  - by Richard Durr

  Seaside is known as "the heretical web framework". One of the points that make it heretical is that it has much shared state. That however is something which, in my current understanding, hinders easy scaling. Ruby on rails on the other hand shares as less state as possible. It has been known to scale pretty well, even if it is dog slow compared to modern smalltalk vms. flickr uses php and has scaled to an extremly big infrastructure... So has anybody some experience in the scaling of Seaside?

• Building an application that includes a DB, and need recommendations

  - by Rubys

  I'm going to build a little system for personal use, and I want it to save data to a database. The language is going to be C#, and so I'd like to use this opportunity to get my head around LINQ to SQL. I have some DB experience and I know my SQL, but it was all in school using Access, which is giving me trouble, and so I'd like to use another DB, something that is small in size, easy to install, and should work with LINQ to SQL. The problem is: I don't know any except Access, and am looking for recommendations. To sum it up: I need a lightweight, easy to install, linq-to-sql supporting database for a small system on a home computer, any recommendations?
