• Pool Billiard AI

  - by Sebi

  Im implementing a pool billiard game in Java and it all works fine. It is a multiplayer game, but nevertheless, it should also be possible to play it alone. For this purpose I'm trying to implement a simple KI. At the moment, the KI choose just randomly a direction and a random intensity of the impulse (don't know the correct english word for that). Of course this AI is very poor and unlikely to ever challenge a player. So i thought about improving the KI, but there are several hard to solve problems. First I thought of just choosing the nearest ball and to try to put it directly into the nearest hole. This isn't that bad, but if there other balls in the line between, it isn't really working anymore. Additionally this dosn't solve te problem of calculating the intensity of the impulse. So are there any general advice? Or any ideas? Best practices?

• trouble configuring WCF to use session

  - by Michael

  I am having trouble in configuring WCF service to run in session mode. As a test I wrote this simple service : [ServiceContract] public interface IService1 { [OperationContract] string AddData(int value); } [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession)] internal class Service1 : IService1,IDisposable { private int acc; public Service1() { acc = 0; } public string AddData(int value) { acc += value; return string.Format("Accumulator value: {0}", acc); } #region IDisposable Members public void Dispose() { } #endregion } I am using Net.TCP binding with default configuration with reliable session flag enabled. As far as I understand , such service should run with no problems in session mode. But , the service runs as in per call mode - each time I call AddData , constructor gets called before executing AddData and Dispose() is called after the call. Any ideas why this might be happening?

• WPF 4.0 Font Rendering Issue

  - by Tom Allen

  I'm getting a weird rendering issue with WPF 4 applications in the way they render some of the text as it's stretching it and making it very narrow. .net 3.5: .net 4.0: At first I thought it could be a problem with the font, but I'm also seeing the same problem in the Blend 4 beta: I'm running XP SP3, Visual Studio 2010 Professional and everything's as up to date as it can be. I'm not noticing any such problems with Silverlight 4 apps I have built on the same machine... Anyone else seen this or know why it's happening?

• Is Lucern.net good choice for website search of 1M item product database? (giving up on SQL Server

  - by Pete Alvin

  We currently have in production SQL Server 2005 and we use it's full text search for a eCommerce site search of a million product database. I've optimized it as much as possible (I think) and we're still seeing search times of five seconds. (We don't need site scrawl or PDF (etc.) document indexing features... JUST "Google" speed for site search.) I was going to buy dtSearch but now I realize I can just use Lucerne.net and save the $2,500 for two server license. I read on a post that Lucerne.Net is not good for website searches. Has anyone else used Lucerne.Net from ASP.Net? Does it take a lot of memory? Any problems? Any comments?

• Detect if a table contains a column in Android/sqlite

  - by sandis

  So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function. Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution. Cheers,

• Getting 401 on Twitter OAuth POST requests

  - by Baishampayan Ghose

  I am trying to use Twitter OAuth and my POST requests are failing with a 401 (Invalid OAuth Request) error. For example, if I want to post a new status update, I am sending a HTTP POST request to https://twitter.com/statuses/update.json with the following parameters - status=Testing&oauth_version=1.0&oauth_token=xxx& oauth_nonce=xxx&oauth_timestamp=xxx&oauth_signature=xxx& oauth_consumer_key=xxx&in_reply_to=xxx&oauth_signature_method=HMAC-SHA1` My GET requests are all working fine. I can see on the mailing lists that a lot of people have had identical problems but I could not find a solution anywhere. I am using the oauth.py Python library.

• PHP-GD: Dealing with Unicode characters

  - by sehugg

  I am developing a web service that renders characters using the PHP GD extension, using a user-selected TTF font. This works fine in ASCII-land, but there are a few problems: The string to be rendered comes in as UTF-8. I would like to limit the list of user-selectable fonts to be only those which can render the string properly, as some fonts only have glyphs for ASCII characters, ISO 8601, etc. In the case where some decorative characters are included, it would be fine to render the majority of characters in the selected font and render the decorative characters in Arial (or whatever font contains the extended glyphs). It does not seem like PHP-GD has support for querying the font metadata sufficiently to figure out if a character can be rendered in a given font. What is a good way to get font metrics into PHP? Is there a command-line utility that can dump in XML or other parsable format?

• Controlling maximum Java standalone running in Linux

  - by Gnanam

  Hi, We've developed a Java standalone program. We've configured in our Linux (RedHat ES 4) cron schedule to execute this Java standalone every 10 minutes. Each standalone may sometime take more than 1 hour to complete, or sometime it may complete even within 5 minutes. My problem/solution I'm looking for is, the number of Java standalones executing at any time should not exceed, for example, 5 threads. So, for example, before even a Java standalone/thread starts, if there are already 5 threads running, then this thread should not be started; otherwise this would indirectly start creating OutOfMemoryError problems. How do I control this? I would also like to make this 5 thread as configurable. Other Information: I've also configured -Xms and -Xmx heap size settings. Is there any tool/mechanism by which we can control this? I also heard about Java Service Wrapper. What is this all about?

• Are jQuery and GWT comparable frameworks?

  - by lomaxx

  At work there's a bit of discussion around what client side framework we should use for our front end web applications. Currently it's a showdown between GWT and jQuery and I'm kind of on the fence but leaning towards jQuery. From what I can tell, GWT and jQuery are trying to solve different problems but are compared to each other because they both end up existing in the web applications space. I suspect that if this is the case, then comparing the two may be fruitless so what I'm trying to get my head around is if comparing jQuery to GWT is even an apples to apples comparison in the same way that jQuery and ExtJS can be compared, or would it be more beneficial for our team to ask certain questions of our application and use the answers to determine which framework is a better fit for us?

• How to build sqlite for Python 2.4?

  - by Verrtex

  I would like to use pysqlite interface between Python and sdlite database. I have already Python and SQLite on my computer. But I have troubles with installation of pysqlite. During the installation I get the following error message: error: command 'gcc' failed with exit status 1 As far as I understood the problems appears because version of my Python is 2.4.3 and SQLite is integrated in Python since 2.5. However, I also found out that it IS possible to build sqlite for Python 2.4 (using some tricks, probably). Does anybody know how to build sqlite for Python 2.4? As another option I could try to install higher version of Python. However I do not have root privileges. Does anybody know what will be the easiest way to solve the problem (build SQLite fro Python 2.4, or install newer version of Python)? I have to mention that I would not like to overwrite the old version version of Python. Thank you in advance.

• iphone - compiler conditional on header

  - by Mike

  I have a project that generates applications for two targets. One of the targets has to include one additional delegate protocol that should not be present on the other one. So, I have created a macro on Xcode and declared the header like this: #ifdef TARGET_1 @interface myViewController : UIViewController <UIScrollViewDelegate, UIPopoverControllerDelegate> #endif #ifdef TARGET_2 @interface myViewController : UIViewController <UIScrollViewDelegate> #endif { .... bla bla.... } The problem is that Xcode is not liking this "double" declaration of @interface and is giving me all sort of problems. How to solve that? thanks for any help.

• Scheme homework problem, need help.

  - by poorStudent

  Okay one of my homework problems is to take a list of lists and return the car of each sublist as a list. I have it to where I can print out the values, but it's not a list. To be honest, I have no clue how to output lists. Here's what I got: (define (car-print alist) (if (null? alist) (newline) (begin (write (car (car alist))) (display " ") (car-print(cdr alist))))) This is a cheap way to do it, perhaps some help on actually solving this problem would be much appreciated. Not necessarily the full answer but steps to get there. Thanks.

• MVVM - RaisePropertyChanged turning code into a mess

  - by vidalsasoon

  New to MVVM so please excuse my ignorance. I THINK i'm using it right but I find my ViewModel has too many of these: RaisePropertyChanged("SomeProperty") Every time I set a property I have to raise that damned property changed. I miss the days where I could just go: public int SomeInteger { get; private set;} These days I have to stick the "RaisePropertyChanged" in everywhere or my UI does not reflect the changes :( Am I doing it wrong or are other people getting annoyed with the excessive number of magic strings and old school property setters? Should I be using dependency properties instead? (I doubt that would help the code bloat anyway) Despite these problems I still think MVVM is the way to go so I guess that's something.

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• Updating the datalist in a RadComboBox

  - by jphenow

  So I'm just struggling with a lot of little things in the web app so I'm checking up with all kinds of stuff to make sure i'm not breaking it cause of stupid problems. At some point in my web app (trying to keep it mostly Asynchronous) I have to update the list in my RadComboBox because something was added. Do I just need to call RadComboBox.DataBind() again? Since I don't explicitly use its datasource(I do it in the manual insert using a string fashion) object to insert my new record do I need to tell that to update? The list just doesn't seem to update when i just call databind so I feel like i need to have the datasource recheck for entries or SOMETHING Thanks

• Boost graph libraries: setting edge weight values

  - by AndyUK

  I am investigating the use of the boost graph libraries in order to apply them to various network problems I have in mind. In the examples I have been looking at the graph edge values ("weights") are always initialized as integers, such as in these Bellman-Ford and Kruskal algorithms eg: int weights[] = { 1, 1, 2, 7, 3, 1, 1, 1 }; My problem is if I try and change the weights to double, I get a heap of warning messages about conversions etc, which so far I have not been able to figure out how to overcome. Does anyone see a way around this?

• ReadOnly Property in Custom Column Types in Sharepoint

  - by Ray Booysen

  Hey all I'm creating a custom column in a feature for Sharepoint. It is essentially this: <Field Type="Integer" ID="<insert guid here>" ReadOnly="true" Name="xxx" DisplayName="XXX" Group="YYY" /> When the field is deployed and attached to a content type, the content type shows no instance of this field being attached. The documentation about ReadOnly is a bit vague but definitely states that the column will be available for viewing in a View. However, when I create a view it is not available. The moment I remove ReadOnly from the field, it is available on the content type without any problems. Any ideas?
