• Make a steady automata in javascript

  - by RobertWHurst

  I'm working on a javascript game and I've got an automata system controlling game time and sprite animation as well as giving a hand to the path finding system for timing and such. My problem is on slow browsers the javascript loop I'm using for counting the time is not very accurate. It tends to jump around a lot. I there a way to force the loop to run consistantly at 30 fps? The automata can drop frames if it needs to catch up so if the solution requires droping frames thats ok.

• What messaging technologies in windows-ce for gauranteed msg delivery?

  - by Aidanapword

  All, We are building a windows-ce (6.0R3) based device that requires guaranteed and audit-ready message delivery (including store & forward) up to and down from the cloud. I have been looking for choices beyond: MSMQ a proprietary solution (what our prototype device is using) AMQP (research on using this in our context is now starting) ... are there any others? We will be transporting sensitive data (who isn't?!?!) over a public network, and large scale options are required. Anything running on an embedded device will be performance sensitive too. Thanks!

• Reading Character from Image

  - by Chinjoo

  I am working on an application which requires matching of numbers from a scanned image file to database entry and update the database with the match result. Say I have image- employee1.jpg. This image will have two two handwritten entries - Employee number and the amount to be paid to the employee. I have to read the employee number from the image and query the database for the that number, update the employee with the amount to be paid as got from the image. Both the employee number and amount to be paid are written inside two boxes at a specified place on the image. Is there any way to automate this. Basically I want a solution in .net using c#. I know this can be done using artificial neural networks. Any ideas would be much appreciated.

• How to skip "Loose Object" popup when running 'git gui'

  - by Michael Donohue

  When I run 'git gui' I get a popup that says This repository currently has approximately 1500 loose objects. It then suggests compressing the database. I've done this before, and it reduces the loose objects to about 250, but that doesn't suppress the popup. Compressing again doesn't change the number of loose objects. Our current workflow requires significant use of 'rebase' as we are transitioning from Perforce, and Perforce is still the canonical SCM. Once Git is the canonical SCM, we will do regular merges, and the loose objects problem should be greatly mitigated. In the mean time, I'd really like to make this 'helpful' popup go away.

• Navigating cursor rows in SQLite

  - by Alan Harris-Reid

  Hi there, I am trying to understand how the following builtin functions work when sequentially processing cursor rows. The descriptions come from the Python 3.1 manual (using SQLite3) Cursor.fetchone() Fetches the next row of a query result set, returning a single sequence. Cursor.fetchmany() Fetches the next set of rows of a query result, returning a list. Cursor.fetchall() Fetches all (remaining) rows of a query result, returning a list. So if I have a loop in which I am processing one row at a time using cursor.fetchone(), and some later code requires that I return to the first row, or fetch all rows using fetchall(), how do I do it? The concept is a bit strange to me, especially coming from a Foxpro background which has the concept of a record pointer which can be moved to the 1st or last row in a cursor (go top/bottom), or go to the nth row (go n) Any help would be appreciated. Alan

• Advantages of three-way automatic merging vs. two-way

  - by bnsmith

  I'm interested in understanding two-way and three-way merging of source code files. Based on what I've read, two-way merging has some "crippling weaknesses" compared to three-way merging. What I'd really like to see are one or two simple, concrete examples of cases where three-way merging is able to automatically merge something from a branch to the trunk without producing conflicts, while two-way merging falls down and requires a bunch of manual intervention to get the code merged. Any links to blog posts or even references to books would be appreciated (yes, I have Googled this for an hour or so). Thanks!

• Creating a proper CMS thoughts

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value. The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• Private JQuery instance

  - by Nir Levy

  We are writing a SaaS like solution that requires our customers to SCRIPT SRC some javascript code we are building (think Google Analytics scenario). We would like to use JQuery. However, since our customers might already have conflicting JQuery versions or other conflicting frameworks (prototype.js for one) we cannot tell them to source jquery.js. We were thinking of coping the jquery source as to create a 'private' jquery instance and simple search/replace the JQuery and $ functions with myJQuery and $J Is there any reason for this not to work? has anyone tried something like this? What can we do about plugins?

• Ruby Methods: how to return an usage string when insufficient arguments are given

  - by Shyam

  Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

• Weird problem: IE8 user can't authenticate with web service

  - by NovaJoe

  I have an asp.net app. It has a page that requires authentication. The authenticated user can view the page because he/she is authenticated. The page makes a jQuery Ajax call to a WCF service. The WCF service checks that the user is authenticated via HttpContext. I have a user that is using WinXP and IE8. This user can authenticate to the page, but when the Ajax call is made from the page to the wb service, the user recieves my "session not authenticated" message on the page, generated by the service and displayed on the page. When I use the same OS/browser combo, the page and service work just fine, as expected; no errors. What option in this user's IE settings would cause this behavior?

• What is the "official" place for community support for the Mere Mortals .NET framework?

  - by Ryan Hayes

  My team is using the Mere Mortals .NET framework from Oak Leaf. Being used to working with primarily open source software, I found it excruciatingly painful to find ANY community support for MM.NET. When I asked if there was any, the only place I was given to look for support was Universal Thread, which is a site which requires a membership for search and archived questions. It seems like a third party, pay-for site should not be the primary source of support for anything like this, especially MM.NET which costs $700 per developer. It doesn' to me like an entire community around MM.NET would choose to all pay on top of the license just to use a forum. If not Universal Thread, then what is the "official" place to find support for the Mere Mortals .NET framework?

• How to make script paths inside user control independent of page hierarchy.

  - by Rohit

  My website is organized in the following folder structure Root Pages CustomerManagement DepartMentManagement Script UserControls Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way <script type="text/javascript" language="javascript" src="../Script/slider.js"></script> My understanding is that since both are under root so i have used a single .. Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work. I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.Please tell me how to achieve this.

• Calling https process from ASP Net

  - by David M

  I have an ASP NET web server application that calls another process running on the same box that creates a pdf file and returns it. The second process requires a secure connection via SSL. The second process has issued my ASP NET application with a digital certificate but I still cannot authenticate, getting a 403 error. The code is a little hard to show but here's a simplified method ... X509Certificate cert = X509Certificate.CreateFromCertFile("path\to\cert.cer"); string URL = "https://urltoservice?params=value"; HttpWebRequest req = HttpWebRequest.Create(URL) as HttpWebRequest; req.ClientCertificates.Add(cert); req.Credentials = CredentialCache.DefaultCredentials; req.PreAuthenticate = true; /// error happens here WebResponse resp = req.GetResponse(); Stream input = resp.GetResponseStream(); The error text is "The remote server returned an error: (403) Forbidden." Any pointers are welcome.

• Jar extraction and verification in BlackBerry

  - by Basilio

  Hi All, The application I am currently working on requires me to extract contents from and verify the authenticity of the signed jar that is stored on the SD Card. In Java [and Android], we have the java.util.jar and java.util.zip classes, that allow to extract jar. However, J2ME or BlackBerry® does not provide support for these packages. I have, however, successfully extracted these using the third party ZipMe library. Can anyone let me know, how to get the signature block from the .DSA/.RSA file to authenticate the jar? I have the certificate that was used to sign the jar as well. This is easily done in Java using the getCertificates() method available in java.util.jar.JarFile. Is there any 3rd party API available that emulates the JarFile for BlackBerry®? Any help in this regard will be deeply appreciated. Thanks & Regards Basilio John Vincent D'souza

• Can documents indexed with Solr on JDK6 be retrieved using only lucene api on JDK1.4?

  - by huynhjl

  My runtime environment is still on JDK1.4 but I like the Solr features related to how documents are ingested and indexed. Would I be able to index my documents using Solr offline on a recent version of the JDK, copy the index over and use it in my runtime environment with an older version of the JDK? Version wise, Solr 1.4.0 uses Apache Lucene 2.9.1 which is JDK1.4 compatible. (but Solr itself requires JDK5). Assuming what I'm trying to do is even possible, what features would I lose if I search Solr indices only with the Lucene API?

• Using Fluent NHibernate with Castle Windsor and the NHibernate Facility

  - by Andrew

  Ive managed to get Fluent NHibernate 1.1 playing nicely with Castle Windsor 2.1. This involved me recompiling NHibernate.ByteCode.Castle.dll and it all works fine. Ive managed to do the same thing this time with Castle Windsor 2.5, havent tried it yet but its not complaining which is good enough for me at the moment. However Im also using the Castle NHibernate Facility and that is another story. The version of the NHibernate Facility that is compatible with Castle 2.5 requires a much later version of NHibernate. Is there an easy way to get the NHibernate Facility to work with NHibernate 2.1 and Castle Core 2.5?

• How do I reuse code in Zend Framework

  - by Mario

  I am working on a web application which requires the user to login before they see or do anything. No part of this app should be accessible without being logged in. (Except of course, the login controller) Currently I am using sessions to handle the authentication and I have put code in each controller in the init() function to check if their session is valid. This was a temporary workaround, but it is redundant and inefficient. I would like my init() function to be similar to the following, but I am not sure how to achieve it: public function init() { // If user not logged in redirect to login controller $myLibrary = Zend_Library_MyLibrary(); $myLibrary->CheckAuth(); } So my question really has two parts: Where is the best place to store code that will be used in multiple controllers? How do I then call that function from a controller? Thanks.

• Write directly to a remote Git repository, without adding objects to a local index/repo?

  - by Ryan B. Lynch

  Does Git support any commands that would allow me to commit directly from a local/working tree into a remote repository? The normal workflow requires a "git add", at least, to populate the object database with copies of the file contents, etc. I understand that this is NOT the normal, expected Git workflow. But I noticed that Git already supports downloading directly from the repository, with no local repo ("git archive"), so it seems reasonable that there might be a similar uploading operation. Alternatively, if there isn't such a command in the core Git itself, does any 3rd-party software support direct remote writes?

• Problem linking SDL_Image against libpng

  - by Tim Jones

  I'm trying to compile SDL_Image 1.2.10 with MinGW + MSys (gcc 4.5.0) on Windows, I have compiled all the requires libs (zlib 1.2.5, libpng 1.4.2, libjpeg 8a, libtiff 3.9.2). SDL_Image compiles fine, but fails to link to libpng, throwing .libs/IMG_png.o:IMG_png.c:(.text+0x16): undefined reference errors on various png structs. If I run ./configure --prefix=/mingw --disable-png for SDL_Image, it compiles and links against the other libs just fine. I have tried older versions of libpng (1.2.43), but they also caused SDL_Image to throw the same errors.

• How can I integrate a bitbucket repository with the hosted on-demand version of FogBugz?

  - by carrier

  I use the on-demand (hosted) version of FogBugz. I would like to start using Mercurial for source control. I would like to integrate FogBugz and a BitBucket repository. I gave it a bit of a try but things weren't going very well. FogBugz requires that you hook up your Mercurial client to a fogbugz.py python script. TortoiseHg doesn't seem to have the hgext directory that they refer to in instructions. So has anyone successfully done something similar?

• Mercurial Messing Up csproj Files?

  - by alphadogg

  I am using Hg to manage and merge code with three other developers involved in a VS2008 project. We do have an .hgignore file that ignores a fair number of files not necessary to track, such as *.pdb, *.obj, etc. However, we do track .csproj files. Periodically, it would seem that files go missing after a merge. We would get build issues, and have to relocate files which were in the project folders, but not in the csproj file. Eventually, I noted during a merge conflict that sometimes Hg seems to merge incorrectly. Here's a screenshot below. The actual conflict that requires manual intervention is lower in the file. But in this section, hg incorrectly replaces DirectoryTasks.cs with a new, different file called ReportTasks.cs, when in fact, both should be added. How do people manage to avoid this?

• Array.BinarySearch does not find item using IComparable

  - by Sir Psycho

  If a binary search requires an array to be sorted before hand, why does the following code work? string[] strings = new[] { "z", "a", "y", "e", "v", "u" }; int pos = Array.BinarySearch(strings, "Y", StringComparer.OrdinalIgnoreCase); Console.WriteLine(pos); And why does this code result return -1? public class Person : IComparable<Person> { public string Name { get; set; } public int Age { get; set; } public int CompareTo(Person other) { return this.Age.CompareTo(other.Age) + this.Name.CompareTo(other.Name); } } var people = new[] { new Person { Age=5,Name="Tom"}, new Person { Age=1,Name="Tom"}, new Person { Age=2,Name="Tom"}, new Person { Age=1,Name="John"}, new Person { Age=1,Name="Bob"}, }; var s = new Person { Age = 1, Name = "Tom" }; // returns -1 Console.WriteLine( Array.BinarySearch(people, s) );

• Can I allow a write access to a particular registry key without elevation?

  - by 280Z28

  I develop an extension for Visual Studio 2005, 2008, and 2010. The Visual Studio 2005 SDK requires write access to the following registry key during builds. The normal way to handle this run Visual Studio with elevated privileges. The entire issue can be avoided if there's some way I can set permissions to allow access to this particular registry key without elevation: HKLM\SOFTWARE\Microsoft\VisualStudio\8.0Exp Side note: This key is only used for testing Visual Studio 2005 extensions. The issue does not occur on client machines so this is just a workaround for my own development machine.
