• Visual Studio 2010 RC &ndash; Silverlight 4 and WCF RIA Services Development - Updates from MIX Anno

  - by Harish Ranganathan

  MIX is happening and there is a lot of excitement around the various releases such as the Windows Phone 7 Developer Preview, IE9 Platform Preview and few other announcements that have been made.  Clearly, the Windows Phone 7 Developer Preview has generated the maximum interest and opened a plethora of opportunities for .NET Developers.  It also takes the mobile development to a new generation and doesn’t force developers to learn different programming language. Along with this, few other releases have been out.  The most anticipated Silverlight 4 RC is out and its corresponding templates are also out there for you to download.  Once VS 2010 RC was released, it was much of a disappointment that it doesn’t support SL4 development as well as the SL4 Business Application Development (a.k.a. WCF RIA Services).   There were few workarounds though nothing concrete.  Earlier I had written about how the WCF RIA Services Preview does work with ASP.NET Development using VS 2010 RC. However, with the release of SL4 RC and the corresponding tooling updates, one can develop for both SL4 as well as SL4 + WCF RIA Services using VS 2010 RC.  This is kind of important and keeps the continuum going until VS 2010 RTMs.  So, the purpose of this post is to quickly give the updates and links to install the relevant tools. Silverlight 4 RC Runtime Windows Runtime or the Mac Runtime Silverlight 4 RC Developer Tools for Visual Studio 2010 RC Silverlight 4 Tools for Visual Studio 2010 (this would install the Runtime as well automatically) Expression Blend 4 Beta Expression Blend 4 Beta If you install the SL4 RC Developer Tools, it also installs the WCF RIA Services Preview automatically.  You just need to install the WCF RIA Services Toolkit that can be downloaded from Install the WCF RIA Services Toolkit Of course you can also just install the WCF RIA Services for VS 2010 RC separately (without SL4 Tools) from here Kindly note, all the above mentioned links are with respect to Visual Studio 2010 RC edition.  If you are developing with VS 2008, then you can just target SL3 (as I write this, there seems to be no official support for developing SL4 with VS 2008) and the related tools can be downloaded from http://www.silverlight.net/getstarted/ Basically you need to download SL 3 Runtime, SDK, Expression Blend 3 and the Silverlight Toolkit.  All the links for the download are available in the above mentioned page. Also, a version of WCF RIA Services that is supported in VS 2008 is available for download at WCF RIA Services Beta for VS 2008 I know there are far too many things to keep in mind.  So, I put a flowchart that could help with depicting it pictorial.  Note that this is just my own imagination and doesn’t cover all scenarios.  for example, if you are neither developing for Webform, Silverlight, you end up nowhere whereas in actual scenario you may want to develop Desktop, Services, Console, Game and what not.  So, keep in mind this is just Web. Cheers !!!

• HTTP 1.0 vs 1.1

  - by Jason Baker

  Could somebody give me a brief overview of the differences between HTTP 1.0 and HTTP 1.1? I've spent some time with both of the RFCs, but haven't been able to pull out a lot of difference between them. Wikipedia says this: HTTP/1.1 (1997-1999) Current version; persistent connections enabled by default and works well with proxies. Also supports request pipelining, allowing multiple requests to be sent at the same time, allowing the server to prepare for the workload and potentially transfer the requested resources more quickly to the client. But that doesn't mean a lot to me. I realize this is a somewhat complicated subject, so I'm not expecting a full answer, but can someone give me a brief overview of the differences at a bit lower level? By this I mean that I'm looking for the info I would need to know to implement either an HTTP server or application. I realize that this can be a somewhat complicated subject (based on what I know about HTTP as of right now), so I'm not necessarily looking for a full answer. I'm really more looking for a nudge in the right direction so that I can figure it out on my own.

• jQuery RJS inserting string vs dom.

  - by Dmitriy Likhten

  So I am trying to use jQuery to insert data from an ajax call. I actually use the jquery.form plugin, and have the ajax form submitted with a dataType: 'script'. The response is a jquery expression which contains a <%= javascript_escape(render ...) %> erb tag (similar to what the railscasts episode 136 instructs to do). However the end result is that the full text of the render is inserted as if that was the content to be inserted into the page, as text, not as dom elements. Could the fact that the render had some newlines at the beginning be the cause? Dom text: "\n \n &lt;li>....&lt;/li>" I also tried having jQuery just read the response as a script and execute it, and used the prototype-based rjs stuff, same effect, the text is inserted into the dom. Are there any reasons why such a behavior would be experienced? A bit of clarification: My response.js.erb is jQuery("#content").append("<%= escape_javascript(render(:partial => "widgets")) %>"); jQuery("#information").text("Finally, something happened!"); The full text inside the append() call is inserted as text into #content.

• Window message procedures in Linux vs Windows

  - by mizipzor

  In Windows when you create a window, you must define a (c++) LRESULT CALLBACK message_proc(HWND Handle, UINT Message, WPARAM WParam, LPARAM LParam); to handle all the messages sent from the OS to the window, like keypresses and such. Im looking to do some reading on how the same system works in Linux. Maybe it is because I fall a bit short on the terminology but I fail to find anything on this through google (although Im sure there must be plenty!). Is it still just one single C function that handles all the communication? Does the function definition differ on different WMs (Gnome, KDE) or is it handled on a lower level in the OS? Edit: Ive looked into tools like QT and WxWidgets, but those frameworks seems to be geared more towards developing GUI extensive applications. Im rather looking for a way to create a basic window (restrict resize, borders/decorations) for my OGL graphics and retrieve input on more than one platform. And according to my initial research, this kind of function is the only way to retrieve that input. What would be the best route? Reading up, learning and then use QT or WxWidgets? Or learning how the systems work and implement those few basic features I want myself?

• XElement vs Dcitionary

  - by user135498

  Hi All, I need advice. I have application that imports 10,000 rows containing name & address from a text file into XElements that are subsequently added to a synchronized queue. When the import is complete the app spawns worker threads that process the XElements by deenqueuing them, making a database call, inserting the database output into the request document and inserting the processed document into an output queue. When all requests have been processed the output queue is written to disk as an XML doc. I used XElements for the requests because I needed the flexibility to add fields to the request during processing. i.e. Depending on the job type the app might require that it add phone number, date of birth or email address to a request based on a name/address match against a public record database. My questions is; The XElements seems to use quite a bit of memory and I know there is a lot of parsing as the document makes its way through the processing methods. I’m considering replacing the XElements with a Dictionary object but I’m skeptical the gain will be worth the effort. In essence it will accomplish the same thing. Thoughts?

• Flex Modules vs RSL

  - by nil

  Hi, I'm a little bit confused about when is better to use Flex Modules or RSL libriaries (in Flex 3.5). My goal is split my project in several unit projects, so I can test and work separately. Let's assume I have a Customer app and Vendor app. I also have a front-end panel with two buttons. Each button launches Customer app or Vendor app. These applications make different things. They share some .as functions and common components, too. I understand that if I make a main project (for user login and to show a first panel) and two modules (customer, vendor) I must have all that components in my Eclipse project, isn't it? Instead of doing modules, should I create SWC for Vendor and other for Customer app and call from main app by using RSL? So, which option is more suitable? What do you advise me? Which are the trade-offs of each option? On the other side, this flex application is integrated with Java through Blaze and ibatis for persistence managment, and hold by a web apache server. I considered also to create independent war files to keep this indpendence, but I thought this do not optimize flex code. I'm right? Thank you. Nil

• SQL vs. Oracle Live Debate (AKA Smackdown!)

  - by Peter W. DeBetta

  A few years ago I was speaking at a conference in Raleigh, NC where Ted Neward and I found a fun way to promote a Java vs. .NET debate that was planned one evening. We stood in the middle of a crowd during one of the breaks and starting “arguing” about Java vs. .NET with one another. Our voice levels quickly raised and we ended it by slapping each other across the face with a glove to request a challenge. It was a great way to segue to our announcing of the actual debate planned later that evening....(read more)

  i am trying to do using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.EMailAddress == "[email protected]" select u; return users.Count(); } however, when i get to: using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses. i do not get offered the EMailAddress name, but rather some neutral default-looking list of options in intelisense. what am i doing wrong? table Users ID bigint NameTitle nvarchar(64) NameFirst nvarchar(64) NameMiddle nvarchar(64) NameLast nvarchar(64) NameSuffix nvarchar(64) Status bigint IsActive bit table UserEMailAddresses ID bigint UserID bigint EMailAddress nvarchar(256) IsPrimary bit IsActive bit obviously, 1 user can have many addresses and so Users.ID and UserEMailAddresses.UserID have a relationship between them: 1 to MANY.

• Can I use AppDomain.AssemblyResolve Event to redirect a failed Assembly Load?

  - by esac

  By default, my application references a mixed mode DLL, so this DLL is both 32 and 64 bit. On a 32 bit system, my app is MSIL and loads the 32 bit DLL. On a 64 bit system, my app loads the 64 bit. However on a 64 bit system, in an older version of the assembly that I am referencing, they only created a 32 bit version. So I fail to load this. I was looking at doing it dynamically, and ideally I would want my MSIL app in 64 bit mode to load the 32 bit DLL. Is this possible? Also it would be nice to resolve it to a different version than what I have referenced as well. Any help appreciated.

• JS/CSS include section replacement, Debug vs Release

  - by Bayard Randel

  I'd be interested to hear how people handle conditional markup, specifically in their masterpages between release and debug builds. The particular scenario this is applicable to is handling concatenated js and css files. I'm currently using the .Net port of YUI compress to produce a single site.css and site.js from a large collection of separate files. One thought that occurred to me was to place the js and css include section in a user control or collection of panels and conditionally display the <link> and <script> markup based on the Debug or Release state of the assembly. Something along the lines of: #if DEBUG pnlDebugIncludes.visible = true #else pnlReleaseIncludes.visible = true #endif The panel is really not very nice semantically - wrapping <script> tags in a <div> is a bit gross; there must be a better approach. I would also think that a block level element like a <div> within <head> would be invalid html. Another idea was this could possibly be handled using web.config section replacements, but I'm not sure how I would go about doing that.

• Vector [] vs copying

  - by sak

  What is faster and/or generally better? vector<myType> myVec; int i; myType current; for( i = 0; i < 1000000; i ++ ) { current = myVec[ i ]; doSomethingWith( current ); doAlotMoreWith( current ); messAroundWith( current ); checkSomeValuesOf( current ); } or vector<myType> myVec; int i; for( i = 0; i < 1000000; i ++ ) { doSomethingWith( myVec[ i ] ); doAlotMoreWith( myVec[ i ] ); messAroundWith( myVec[ i ] ); checkSomeValuesOf( myVec[ i ] ); } I'm currently using the first solution. There are really millions of calls per second and every single bit comparison/move is performance-problematic.

• Void* array casting to float, int32, int16, etc.

  - by Griffin

  Hey guys, I've got an array of PCM data, it could be 16 bit, 24 bit packed, 32 bit, etc.. It could be signed, or unsigned, and it could be 32 or 64 bit floating point. It is currently stored as a "void**" matrix, indexed by channel, then by frame. The goal is to allow my library to take in any PCM format and buffer it, without requiring manipulation of the data to fit a designated structure. If the A/D converter spits out 24 bit packed arrays of interleaved PCM, I need to accept it gracefully. I also need to support 16 bit non interleaved, as well as any permutation of the above formats. I know the bit depth and other information at runtime, and I'm trying to code efficiently while not duplicating code. What I need is an effective way to cast the matrix, put PCM data into the matrix, and then pull it out later. I can cast the matrix to int32_t, or int16_t for the 32 and 16 bit signed PCM respectively, I'll probably have to store the 24 bit PCM in an int32_t for 32 bit, 8 bit byte systems as well. Can anyone recommend a good way to put data into this array, and pull it out later? I'd like to avoid large sections of code which look like: switch( mFormat ) { case 1: // unsigned 8 bit for( int i = 0; i < mChannels; i++ ) framesArray = (uint8_t*)pcm[i]; break; case 2: // signed 8 bit for( int i = 0; i < mChannels; i++ ) framesArray = (int8_t*)pcm[i]; break; case 3: // unsigned 16 bit ... Limitations: I'm working in C/C++, no templates, no RTTI, no STL. Think embedded. Things get trickier when I have to port this to a DSP with 16 bit bytes. Does anybody have any useful macros they might be willing to share? Thanks, -Griff

• Trial vs free with limited functionality

  - by Morten K

  Hi everyone, Not a programming question as such, but a bit more business oriented question about software product development. We have just released a small app, and is offering a free, fully functional trial which lasts for 15 days. I have the gut feeling however, that to reach any kind of penetration on the web, we'd need to offer a version which is free forever, but then has a few limitations in terms of functionality (still quite usable, but not full-throttle). For example, the Roboform browser plugin is somewhat similar in purpose to ours. Not functionality wise, but it's basically a little util that saves time and removes some repetitive-action pain. They offer a free version with limitations and then a pro version for around 30 USD. Roboform has gotten very much attention over the years, and I can't help to think that this is because they have a product which is obviously good, but also free, thus adoption becomes much higher than if they had only offered a 15 day trial. I am wondering if any of you have experience in a similar scenario? Or any thoughts on the two models? Again, I know it's not directly programming related, but it's still a question I feel best answered by a community of developers.

• C++ STL Map vs Vector speed

  - by sub

  In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.). At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted. Then I though using a map, in my case map<string,symbol>, would be better than iterating through the vector all the time but: It's a bit hard to explain this part but I'll try. If a variable is retrieved the first time in a program in my language, of course its position in the symbol table has to be found (using vector now). If I would iterate through the vector every time the line gets executed (think of a loop), it would be terribly slow (as it currently is, nearly as slow as microsoft's batch). So I could use a map to retrieve the variable: SymbolTable[ myVar.Name ] But think of the following: If the variable, still using vector, is found the first time, I can store its exact integer position in the vector with it. That means: The next time it is needed, my interpreter knows that it has been "cached" and doesn't search the symbol table for it but does something like SymbolTable.at( myVar.CachedPosition ). Now my (rather hard?) question: Should I use a vector for the symbol table together with caching the position of the variable in the vector? Should I rather use a map? Why? How fast is the [] operator? Should I use something completely different?

• Pros and cons of integrated vs. standalone tools [closed]

  - by eckes

  When it comes to version control, for example, there seem to be two different types of users: those using standalone VCS tools those using integrated tools from their IDE In my opinion, both have pros: Integrated tools do everything out of the IDE, no need to leave the environment you're used to ... Standalone tools usable for every type of project, not only for those associated with an IDE always behave the same (e.g. no difference like Eclipse-SVN-Client vs. AnkhSVN client for VS) ... I would be interested in your opinions and use cases.

• How to design 2D collision callback methods?

  - by Ahmed Fakhry

  In a 2D game where you have a lot of possible combination of collision between objects, such as: object A vs object B = object B vs A; object A vs object C = object C vs A; object A vs object D = object D vs A; and so on ... Do we need to create callback methods for all single type of collision? and do we need to create the same method twice? Like, say a bullet hits a wall, now I need a method to penetrate the wall for the wall, and a method to destroy the bullet for the bullet!! At the same time, a bullet can hit many objects in the game, and hence, more different callback methods!!! Is there a design pattern for that?

• starting with flex - please let me know if the direction is right (ActionScript vs MXML separation)

  - by Piotr

  Hi, I've just started learning flex using OReilly "Programming Flex 3.0". After completing three chapters and starting fourth (ActionScript), and not having enough patience to wait till completing chapter 22 I started to practice :) One bit that I have most worries about right now is the the dual coding mode (MXML vs ActionScript) Please have a look at my code below (it compiles via mxmlc design.mxml, second file 'code.as' should be in same directory) and advise if the separation I used between visual design and code is appropriate. Also - if some smart guy could show me how to recode same example with *.as being a class file [package?] it would be highly appreciated. I got lost with creating directory structure for package - and did not find it most intuitive, especially for small project that has two files like my example.

• Node.js vs PHP processing speed

  - by Cody Craven

  I've been looking into node.js recently and wanted to see a true comparison of processing speed for PHP vs Node.js. In most of the comparisons I had seen, Node trounced Apache/PHP set ups handily. However all of the tests were small 'hello worlds' that would not accurately reflect any webpage's markup. So I decided to create a basic HTML page with 10,000 hello world paragraph elements. In these tests Node with Cluster was beaten to a pulp by PHP on Nginx utilizing PHP-FPM. So I'm curious if I am misusing Node somehow or if Node is really just this bad at processing power. Note that my results were equivalent outputting "Hello world\n" with text/plain as the HTML, but I only included the HTML as it's closer to the use case I was investigating. My testing box: Core i7-2600 Intel CPU (has 8 threads with 4 cores) 8GB DDR3 RAM Fedora 16 64bit Node.js v0.6.13 Nginx v1.0.13 PHP v5.3.10 (with PHP-FPM) My test scripts: Node.js script var cluster = require('cluster'); var http = require('http'); var numCPUs = require('os').cpus().length; if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('death', function (worker) { console.log('worker ' + worker.pid + ' died'); }); } else { // Worker processes have an HTTP server. http.Server(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n'); for (var i = 0; i < 10000; i++) { res.write('<p>Hello world</p>\n'); } res.end('</body>\n</html>'); }).listen(80); } This script is adapted from Node.js' documentation at http://nodejs.org/docs/latest/api/cluster.html PHP script <?php echo "<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n"; for ($i = 0; $i < 10000; $i++) { echo "<p>Hello world</p>\n"; } echo "</body>\n</html>"; My results Node.js $ ab -n 500 -c 20 http://speedtest.dev/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: Server Hostname: speedtest.dev Server Port: 80 Document Path: / Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 14.603 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95066500 bytes HTML transferred: 95035000 bytes Requests per second: 34.24 [#/sec] (mean) Time per request: 584.123 [ms] (mean) Time per request: 29.206 [ms] (mean, across all concurrent requests) Transfer rate: 6357.45 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 2 Processing: 94 547 405.4 424 2516 Waiting: 0 331 399.3 216 2284 Total: 95 547 405.4 424 2516 Percentage of the requests served within a certain time (ms) 50% 424 66% 607 75% 733 80% 813 90% 1084 95% 1325 98% 1843 99% 2062 100% 2516 (longest request) PHP/Nginx $ ab -n 500 -c 20 http://speedtest.dev/test.php This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: nginx/1.0.13 Server Hostname: speedtest.dev Server Port: 80 Document Path: /test.php Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 0.130 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95109000 bytes HTML transferred: 95035000 bytes Requests per second: 3849.11 [#/sec] (mean) Time per request: 5.196 [ms] (mean) Time per request: 0.260 [ms] (mean, across all concurrent requests) Transfer rate: 715010.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 1 Processing: 3 5 0.7 5 7 Waiting: 1 4 0.7 4 7 Total: 3 5 0.7 5 7 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 6 95% 6 98% 6 99% 6 100% 7 (longest request) Additional details Again what I'm looking for is to find out if I'm doing something wrong with Node.js or if it is really just that slow compared to PHP on Nginx with FPM. I certainly think Node has a real niche that it could fit well, however with these test results (which I really hope I made a mistake with - as I like the idea of Node) lead me to believe that it is a horrible choice for even a modest processing load when compared to PHP (let alone JVM or various other fast solutions). As a final note, I also tried running an Apache Bench test against node with $ ab -n 20 -c 20 http://speedtest.dev/ and consistently received a total test time of greater than 0.900 seconds.

• Trac vs. Redmine vs. JIRA vs. FogBugz for one-man shop?

  - by kizzx2

  Background I am a one-man freelancer looking for a project management software that can provide the following requirements. I have used Trac for about a year now. Tried Redmine and FogBugz on Demand for a couple of weeks. Never tried JIRA before. Basically, I'm looking for a piece of software that: Facilitates developer-client communication/collaboration Does time tracking Requirements Record time estimates/Time tracking Clients must be able to create/edit his own tickets/cases Clients must not see Developer created tickets/cases (internal) Affordable (price) with multiple clients Nice-to-haves Supports multiple projects in one installation Free eclipse integration (Mylyn) Easy time-tracking without using the Web UI (Trac's post commit hook or Redmine's commit message scanning) Clients can access the Wiki Export the data to standard formats My evaluation Trac can basically fulfill most of the above requirements, but with lots of customizations and plug-ins that it doesn't feel so clean. One downside is that the main trunk (0.11) has been around for a year or more and I still haven't seen much tendency of any upgrades coming up. Redmine has the cleanest Web UI. It's design philosophy seems to be the most elegant, with its innovative commit message scanning and stuff. However, the current version doesn't seem to be very mature and stable yet. It doesn't support internal (private) tickets and the time-tracking commit message patch doesn't support the trunk version. The good thing about it is that the main trunk still seems to be actively developed. FogBugz is actually a very well written piece of software. However the idea of paying $25/month for the client to be able to log-in to the system seems a little bit too far off for an individual developer. The free version supports letting clients create/view their own cases using email, which is a sub-optimal alternative to having a full-fledged list of the user's own cases. That also means clients can't read/write wiki pages. Its time-tracking approach is innovative and good though. However the fact that all the eclipse integration (Bugclipse, Foglyn) are commercial. Yet other investments before I can use my bug-tracker! If I revert back to the Web UI, it's not really a fast rendering Web service. Also, the in-built report functions are excellent (e.g. evidence based scheduling) JIRA is something I have zero experience with. Can someone with JIRA experience recommend why it might be a good fit for this particular situation? Question Can we share experience on this? Any specific plugins/customizations would that would best suit the requirements for this case?

• Crazy VS Designer Errors

  - by BlueRaja

  Here's a strange one. After renaming a class, one of my forms began giving me errors in the designer, refusing to open. Funny thing is, the form worked just fine when I ran the program. I began reverting my changes to deduce the problem. I have now reverted completely back to the last commit - in which I know the form was working in the designer - cleaned the solution, and deleted the bin/ and obj/ folders, as well as the *.suo file for good measure. The form still does not display in designer. Here are the errors it gives: Could not find 'MyNamespace.MyControl'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built. The variable 'myControl1' is either undeclared or was never assigned. The variable is both declared and assigned, and MyControl builds fine (again, the form works fine when the program is actually run). Stranger still, if I try to create a new form and drag a MyControl onto it, I get this Entity-Framework error: Failed to create component 'MyControl'. The error message follows: 'System.ArgumentException: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. at System.Data.EntityClient.EntityConnection.ChangeConnectionString(String newConnectionString) at System.Data.EntityClient.EntityConnection..ctor(String connectionString) at System.Data.Objects.ObjectContect.CreateEntityConnection(String connectionString) etc. etc. There is nothing wrong with my connection string: it worked before, and, again, it works when I actually run the program (the control already exists on the old form from the previous commit). Any ideas whatsoever? I am completely at a loss. [Edit] The only significant code: MyControl.cs public MyControl() { _entities = new MyEFEntities(); //Entity-framework generated class } MyForm.Designer.cs private void InitializeComponent() { this.myControl1 = new MyNamespace.MyControl(); ... this.Controls.Add(this.myControl1); } MyEFDatabase.Designer.cs public MyEFEntities() : base("name=MyEFEntities", "MyEFEntities") { ... } App.Config <connectionStrings> <add name="MyEFEntities" connectionString="metadata=res://*/MyEFDatabase.csdl|res://*/MyEFDatabase.ssdl|res://*/MyEFDatabase.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MyDatabaseServer;Initial Catalog=MyDatabase;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> I've tried the "replace &quot; with '" trick - didn't help. [Edit2] It is happening to new projects also, but not immediately. Only after fiddling around a bit (it has something to do with adding a many-to-one relationship that EF did not figure out on its own), but I can't figure out the exact steps to reproduce.

• agent-based simulation: performance issue: Python vs NetLogo & Repast

  - by max

  I'm replicating a small piece of Sugarscape agent simulation model in Python 3. I found the performance of my code is ~3 times slower than that of NetLogo. Is it likely the problem with my code, or can it be the inherent limitation of Python? Obviously, this is just a fragment of the code, but that's where Python spends two-thirds of the run-time. I hope if I wrote something really inefficient it might show up in this fragment: UP = (0, -1) RIGHT = (1, 0) DOWN = (0, 1) LEFT = (-1, 0) all_directions = [UP, DOWN, RIGHT, LEFT] # point is just a tuple (x, y) def look_around(self): max_sugar_point = self.point max_sugar = self.world.sugar_map[self.point].level min_range = 0 random.shuffle(self.all_directions) for r in range(1, self.vision+1): for d in self.all_directions: p = ((self.point[0] + r * d[0]) % self.world.surface.length, (self.point[1] + r * d[1]) % self.world.surface.height) if self.world.occupied(p): # checks if p is in a lookup table (dict) continue if self.world.sugar_map[p].level > max_sugar: max_sugar = self.world.sugar_map[p].level max_sugar_point = p if max_sugar_point is not self.point: self.move(max_sugar_point) Roughly equivalent code in NetLogo (this fragment does a bit more than the Python function above): ; -- The SugarScape growth and motion procedures. -- to M ; Motion rule (page 25) locals [ps p v d] set ps (patches at-points neighborhood) with [count turtles-here = 0] if (count ps > 0) [ set v psugar-of max-one-of ps [psugar] ; v is max sugar w/in vision set ps ps with [psugar = v] ; ps is legal sites w/ v sugar set d distance min-one-of ps [distance myself] ; d is min dist from me to ps agents set p random-one-of ps with [distance myself = d] ; p is one of the min dist patches if (psugar >= v and includeMyPatch?) [set p patch-here] setxy pxcor-of p pycor-of p ; jump to p set sugar sugar + psugar-of p ; consume its sugar ask p [setpsugar 0] ; .. setting its sugar to 0 ] set sugar sugar - metabolism ; eat sugar (metabolism) set age age + 1 end On my computer, the Python code takes 15.5 sec to run 1000 steps; on the same laptop, the NetLogo simulation running in Java inside the browser finishes 1000 steps in less than 6 sec. EDIT: Just checked Repast, using Java implementation. And it's also about the same as NetLogo at 5.4 sec. Recent comparisons between Java and Python suggest no advantage to Java, so I guess it's just my code that's to blame? EDIT: I understand MASON is supposed to be even faster than Repast, and yet it still runs Java in the end.

• iPhone Image Resources, ICO vs PNG, app bundle filesize

  - by Jasarien

  My application has a collection of around 1940 icons that are used throughout. They're currently in ICO and new images provided to me come in ICO format too. I have noticed that they contain a 16x16 and 32x32 representation of each icon in one file. Each file is roughly 4KB in filesize (as reported by finder, but ls reports that they vary from being ~1000 bytes to 5000 bytes) A very small number of these icons only contain the 32x32 representation, and as a result are only around 700 bytes in size. Currently I am bundling these icons with my application and they are inflating the size of the app a bit more than I would like. Altogether, the images total just about 25.5MB. Xcode must do some kind of compression because the resulting app bundle is about 12.4MB. Compressing this further into a ZIP (as it would be when submitted to the App Store), results in a final file of 5.8MB. I'm aware that the maximum limit for over the air App Store downloads has been raised to 20MB since the introduction of the iPad (I'm not sure if that extends to iPhone apps as well as iPad apps though, if not the limit would be 10MB). My worry is that new icons are going to be added (sometimes up to 10 icons per week), and will continue to inflate the app bundle over time. What is the best way to distribute these icons with my app? Things I've tried and not had much success with: Converting the icons from ICO to PNG: I tried this in the hopes that the pngcrush utility would help out with the filesize. But it appears that it doesn't make much of a difference between a normal PNG and a crushed png (I believe it just optimises the image for display on the iPhone's GPU rather than compress it's size). Also in going from ICO to PNG actually increased the size of the icon file... Zipping the images, and then uncompressing them on first run. While this did reduce the overall image sizes, I found that the effort needed to unzip them, copy them to the documents folder and ensure that duplication doesn't happen on upgrades was too much hassle to be worth the benefit. Also, on original and 3G iPhones unzipping and copying around 25MB of images takes too long and creates a bad experience... Things I've considered but not yet tried: Instead of distributing the icons within the app bundle, host them online, and download each icon on demand (it depends on the user's data as to which icons will actually be displayed and when). Issues with this is that bandwidth costs money, and image downloads will be bandwidth intensive. However, my app currently has a small userbase of around 5,500 users (of which I estimate around 1500 to be active based on Flurry stats), and I have a huge unused bandwidth allowance with my current hosting package. So I'm open to thoughts on how to solve this tricky issue.
