• What C#/SQL Server feature did someone show you that made you say Wow!

  - by Randy Minder

  It's late Friday afternoon, and my mind is checking out for the week. So I thought I'd ask a light-hearted, interesting, question. Yesterday a co-worker showed me how he managed to save quite a bit of code and improve code reuse through the use of an anonymous delegate and the use of the Action function. My first thought was, "Wow, I had no idea you could do that!". I'm curious what sort of things someone showed you, either in c# or SQL Server, that made you stop and think, "Wow!". Randy

• Powershell 2.0 error handling - Command line call vs. ISE

  - by Gromix

  Hi, In the context of deployment scripts, I would like to capture any error than happens and stop immediately. I have notice some significant differences between the following calls: powershell.exe -File Script.ps1 powershell.exe -Command "& '.\Script.ps1'" powershell.exe .\Script.ps1 For example, the -File call will handle errors in the exact same way as the ISE. The other two seem to ignore the $ErrorActionPreference variable, and do not seem to catch Write-Error in try/catch blocks. Could someone help me understand the implications of each one, and why they are behaving differently? Thanks, Romain

• Why do socket.makefile objects fail after the first read for UDP sockets?

  - by Eli Courtwright

  I'm using the socket.makefile method to create a file-like object on a UDP socket for the purposes of reading. When I receive a UDP packet, I can read the entire contents of the packet all at once by using the read method, but if I try to split it up into multiple reads, my program hangs. Here's a program which demonstrates this problem: import socket from sys import argv SERVER_ADDR = ("localhost", 12345) sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) sock.bind(SERVER_ADDR) f = sock.makefile("rb") sock.sendto("HelloWorld", SERVER_ADDR) if "--all" in argv: print f.read(10) else: print f.read(5) print f.read(5) If I run the above program with the --all option, then it works perfectly and prints HelloWorld. If I run it without that option, it prints Hello and then hangs on the second read. I do not have this problem with socket.makefile objects when using TCP sockets. Why is this happening and what can I do to stop it?

• OpenLayers .containsPoint after pan

  - by Adrian

  I've seem to have hit a bug or i have overlooked something. I written some code that enumerates through all the vector features on a OpenLayers Vector layer - to check if the mouse is inside a vector feature - if so then it displays some info based on the feature. I had to write my own methods to do this because the existing OpenLayers Controls( select etc) stop after finding a feature under the mouse, and i the possibility of several features being stacked on top of one another. My problem is that the .containsPoint method seems to be using coords from before a 'pan'. After zooming in or out the geometry seems to be in the right place and .containsPoint is works correctly when I wave the mouse over the map. Do I need to do something after the map has been panned to update something( feature's geometry)

• If I want to play the same sound 10 times per second, must I have 10 copies of that sound in memory?

  - by mystify

  I have a sound that needs to get played 10 times per second. The sound is 1 second long. So it does overlap like 10 times. However, as far as I understand the Finch sound library, I would need 10 different instances of a sound in place so that I can play it 10 times at almost the same time. When I have just one instance, the sound would stop and play from the beginning on every iteration, but not overlap with itself. How to do that?

  The following code is throwing the error "this.element is null". However, the wid_cont is definitely grabbing an element. window.addEvent('domready',function(){ var min = $(document.body).getElements('a.widget_minimize'); min.addEvent('click', function(event){ event.stop(); //var box = ; var wid_cont = ($(this).getParents('.widget_box').getElement('.widget_box_content_cont')); var myVerticalSlide = new Fx.Slide(wid_cont); myVerticalSlide.slideOut(); } ); }); It's moo tools 1.2.4 and has the fx.slide included....

• Problem With HTML5 Application Cache Whitelist - Won't Ignore Items

  - by Ryan Donnelly

  I'm trying to use HTML5 Application Cache to speed some things up on an iPhone webapp. It works great for storing images, css and JS, but the problem is that it also tries to store the HTML. I haven't been able to get it to ignore the html and stop storing it in the cache. From what I've read, I have to "whitelist" the files and directories that I want to load no matter what. I've tried listing the files I want cached explicitly, and I've tried adding a series of things under the "NETWORK:" heading. I've tried * / /* http://mysite.com http://mysite.com/ http://mysite.com/* None of them seem to work. Is there any way to ignore HTML files by MIME-Type or anything? Any advice would be appreciated. Ryan P.S. Of course, my site is not mysite.com..I just used that for simplicity.

• pySerial writes to Arduino Uno get buffered

  - by Bhaktavatsalam Nallanthighal

  I have a Python script that writes short messages to the serial port on my Arduino Uno board using pySerial. There is a loop and depending on some conditions, multiple writes can happen within a loop, something like this: while True: #Conditions block 1 if <CONDITION1>: serial.writelines("INIT") elif <CONDITION2>: serial.writelines("NEW") ... #Conditions block 2 if <CONDITION1>: # Fetch something from the Internet serial.writelines("CHECK") elif <CONDITION2>: # Fetch something from the Internet serial.writelines("STOP") ... But, when my Arduino board receives this it receives the first message as INIT, but the second one is being read as INITSTOP or INITCHECK and third one gets concatenated to the previous messages. My arduino program checks for specific message in this way: if(msg.equals("CHECK")) { // Do something } else if(msg.equals("INIT")) { // Do Something else } Can anyone guide me on this? BTW, I don't think the problem is with the Arduino as it works perfectly when I test it with the Serial Monitor available with the IDE. I've tried adding sleeps of upto 10 seconds before every write, but that did not work out.

• emacs indentation in asm mode

  - by Gauthier

  I am looking for the equivalent of c-indent-level and ruby-indent-level, for asm-mode. That is, I want to force the indentation to 4 spaces, and I want them to be replaced with blanks. What I've seen tells me it does not exist for asm-mode. Could someone please tell me this is wrong? I tried this also: http://stackoverflow.com/questions/69934/set-4-space-indent-in-emacs-in-text-mode , to no av. I have tried: (setq tab-width 4) (setq indent-line-function 'insert-tab) (setq asm-indent-level 4) This works however: (custom-set-variables '(tab-stop-list (quote (4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120)))) But I wonder if there is a way to define that for asm-mode only. What if I wanted to keep the default tab behaviour for other modes?

• Hyperlinks to download files without stopping the current page load

  - by Evgeny

  I've got an ASP.NET page that takes a long time to download and returns partial results as it's loading (as per my previous question). On the page I have some links to download files, ie. the response headers contain "Content-Disposition: attachment", so that the browser doesn't navigate away from the page. However, if the user clicks one of these links while the page is still loading it stops loading - normal behaviour, but not what I want in this case. I can get around that by adding target=_"blank" to the links, but this momentarily opens a new window and the closes it again (once the browser realises it's an "attachment"). Is there any way to avoid having those links stop the current page load without this new window trick? JavaScript is OK.

• Using 'load' in octave

  - by lollygagger

  Is there a way to tell the load function to only load until a certain line? I want to read in a data file and assign the numbers to an array, however, I want it to stop after it has created a 200 X 200. Could I also do this with a do-while loop and fgetl? When I try to use fgetl(fid, len) and give it 'len', it does not obey :-/ How can I tell octave to ignore the comment lines in an input file? They are '#' characters, so I figured octave would just automatically ignore them, but not so... Thanks.

• Approaches for memcached sessions

  - by Industrial

  Hi everybody, I was thinking about using memcached to store sessions instead of mySQL, which seemed like a good idea, at first. When it comes to the failover part of utilizing memcached servers, It's a bit worrying that my sessions will stop working if the memcached would go offline. It will certainly affect my users. There's a few techniques that we already utilize to reduce failover, including having a pool of servers available to compensate in the event of downtime, utilizing sharding/consistent hashing across the server pool and so on. We would also do some sort of graceful degradation that tells the users that something have gone wrong and they are welcome to login again, in the event of them being kicked out due to memcached server failover. So how does people generally deal with these issues when storing sessions on memcached servers?

• recv returns old data

  - by anon

  This loop is supposed to take data from a socket line by line and put it in a buffer. For some reason, when there is no new data to return, recv returns the last couple lines it got. I was able to stop the bug by commenting out the first recv, but then I cant tell how long the next line will be. I know it's not a while(this->connected){ memset(buf, '\0', sizeof(buf)); recv(this->sock, buf, sizeof(buf), MSG_PEEK); //get length of next message ptr = strstr(buf, "\r\n"); if (ptr == NULL) continue; err = recv(this->sock, buf, (ptr-buf), NULL); //get next message printf("--%db\n%s\n", err, buf); tok[0] = strtok(buf, " "); for(i=1;tok[i-1]!=NULL;i++) tok[i] = strtok(NULL, " "); //do more stuff }

• Building a case for solr

  - by Midhat

  Our product consists of multiple applications, All using Lucene. 2 of the applications I am involved with have Lucene indexes of about 3 GB and 12GB. Another team is building an application, for which they estimate the LUCENE INDEX size to be close to 1 Terabyte. New documents are added to the indexes every 15 days approx. We do not have any apparent performance issues with the current applications. So my question is SHould we be using Solr now? When should one stop using Lucene and graduate to Solr? Any disadvantages/problems for using Solr? The client applications are made in ASP.Net, but I assume they will be able to use a solr server using solrnet

• As our favorite imperative languages gain functional constructs, should loops be considered a code s

  - by Michael Buen

  In allusion to Dare Obasanjo's impressions on Map, Reduce, Filter (Functional Programming in C# 3.0: How Map/Reduce/Filter can Rock your World) "With these three building blocks, you could replace the majority of the procedural for loops in your application with a single line of code. C# 3.0 doesn't just stop there." Should we increasingly use them instead of loops? And should be having loops(instead of those three building blocks of data manipulation) be one of the metrics for coding horrors on code reviews? And why? [NOTE] I'm not advocating fully functional programming on those codes that could be simply translated to loops(e.g. tail recursions) Asking for politer term. Considering that the phrase "code smell" is not so diplomatic, I posted another question http://stackoverflow.com/questions/432492/whats-the-politer-word-for-code-smell about the right word for "code smell", er.. utterly bad code. Should that phrase have a place in our programming parlance?

• Is there a way to create custom UIDataDetectorTypes?

  - by KingAndrew

  Hi All, What I am trying to do is create tooltip functionality so that certain words in my instructional app can be tapped and the definition pops up. For the popup part I plan on using code from “AFInformationView” which provides bubbles on the iPhone. The part I'm struggling with is how to associate A particular word's location with the bubble. Currently I have the text on a UILabel that is on a custom UITableCell. Since I calculate the row height on the fly with: [textToUse sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:CGSizeMake(stop-start, 500)]; I'm not sure what the coordinates for a specific word will be. I was thinking that if I created a custom DataDetectorType that could be the fix. If anyone knows how to do this or has any other ideas I would be happy to hear them. Thanks, Andrew

• jCarousel, IE6 and Fixed Width

  - by Pat Long - Munkii Yebee

  We are using jCarousel on our websites to display images. Simple enough. We have fairly flexible layouts so the carousels are not always the same width. FF, IE7+, Chrome, Safari etc work perfectly well taking up the space available. However IE6 ends up sending the jCarousel script into a loop and warns that a script is stopping the page from loading correctly. To stop IE6 from failing we are having to specify a fixed width in CSS for the carousel container. Is this a problem that others have had with IE6 and jCarousel?

• flash video covering JQueryUI model dialog

  - by user200295

  I have a site with a flash SWF on the home page. I have a login dialog that is displayed using the jquery ui modal. The modal dialog is being covered by the SWF movie when it opens. I tried setting the z-index etc but nothing seems to stop the SWF from covering the log in. Is there any way to force the SWF movie to the background? The SWF uses src="support/AC_RunActiveContent.js" if that helps isolate the version.

• Ajax And REST: Can I send an ajax request to a REST service and recieve response?

  - by Morteza M.

  Hi everybody here, I want to use mootools and SqueezBox class to handle a request to a RESTful service. I don't want to use any server-side script. I am using AJAX. I send a request to the following url using GET method. http://www.idevcenter.com/api/v1/links/links-upcoming.json but I receive a 404 error. Is it because cross-site scripting? here is my code: SqueezeBox.initialize({handler:'url',ajaxOptions:{method:'GET'}}); $('a.modal').addEvent('click',function(e){ new Event(e).stop(); SqueezeBox.fromElement($('a.modal')); }); In Firebug console, sometimes 'aborted' is shown and sometimes '404'.what is wrong with that?

• Getting a NullPointerException at seemingly random intervals, not sure why

  - by Miles

  I'm running an example from a Kinect library for Processing (http://www.shiffman.net/2010/11/14/kinect-and-processing/) and sometimes get a NullPointerException pointing to this line: int rawDepth = depth[offset]; The depth array is created in this line: int[] depth = kinect.getRawDepth(); I'm not exactly sure what a NullPointerException is, and much googling hasn't really helped. It seems odd to me that the code compiles 70% of the time and returns the error unpredictably. Could the hardware itself be affecting it? Here's the whole example if it helps: // Daniel Shiffman // Kinect Point Cloud example // http://www.shiffman.net // https://github.com/shiffman/libfreenect/tree/master/wrappers/java/processing import org.openkinect.*; import org.openkinect.processing.*; // Kinect Library object Kinect kinect; float a = 0; // Size of kinect image int w = 640; int h = 480; // We'll use a lookup table so that we don't have to repeat the math over and over float[] depthLookUp = new float[2048]; void setup() { size(800,600,P3D); kinect = new Kinect(this); kinect.start(); kinect.enableDepth(true); // We don't need the grayscale image in this example // so this makes it more efficient kinect.processDepthImage(false); // Lookup table for all possible depth values (0 - 2047) for (int i = 0; i < depthLookUp.length; i++) { depthLookUp[i] = rawDepthToMeters(i); } } void draw() { background(0); fill(255); textMode(SCREEN); text("Kinect FR: " + (int)kinect.getDepthFPS() + "\nProcessing FR: " + (int)frameRate,10,16); // Get the raw depth as array of integers int[] depth = kinect.getRawDepth(); // We're just going to calculate and draw every 4th pixel (equivalent of 160x120) int skip = 4; // Translate and rotate translate(width/2,height/2,-50); rotateY(a); for(int x=0; x<w; x+=skip) { for(int y=0; y<h; y+=skip) { int offset = x+y*w; // Convert kinect data to world xyz coordinate int rawDepth = depth[offset]; PVector v = depthToWorld(x,y,rawDepth); stroke(255); pushMatrix(); // Scale up by 200 float factor = 200; translate(v.x*factor,v.y*factor,factor-v.z*factor); // Draw a point point(0,0); popMatrix(); } } // Rotate a += 0.015f; } // These functions come from: http://graphics.stanford.edu/~mdfisher/Kinect.html float rawDepthToMeters(int depthValue) { if (depthValue < 2047) { return (float)(1.0 / ((double)(depthValue) * -0.0030711016 + 3.3309495161)); } return 0.0f; } PVector depthToWorld(int x, int y, int depthValue) { final double fx_d = 1.0 / 5.9421434211923247e+02; final double fy_d = 1.0 / 5.9104053696870778e+02; final double cx_d = 3.3930780975300314e+02; final double cy_d = 2.4273913761751615e+02; PVector result = new PVector(); double depth = depthLookUp[depthValue];//rawDepthToMeters(depthValue); result.x = (float)((x - cx_d) * depth * fx_d); result.y = (float)((y - cy_d) * depth * fy_d); result.z = (float)(depth); return result; } void stop() { kinect.quit(); super.stop(); } And here are the errors: processing.app.debug.RunnerException: NullPointerException at processing.app.Sketch.placeException(Sketch.java:1543) at processing.app.debug.Runner.findException(Runner.java:583) at processing.app.debug.Runner.reportException(Runner.java:558) at processing.app.debug.Runner.exception(Runner.java:498) at processing.app.debug.EventThread.exceptionEvent(EventThread.java:367) at processing.app.debug.EventThread.handleEvent(EventThread.java:255) at processing.app.debug.EventThread.run(EventThread.java:89) Exception in thread "Animation Thread" java.lang.NullPointerException at org.openkinect.processing.Kinect.enableDepth(Kinect.java:70) at PointCloud.setup(PointCloud.java:48) at processing.core.PApplet.handleDraw(PApplet.java:1583) at processing.core.PApplet.run(PApplet.java:1503) at java.lang.Thread.run(Thread.java:637)

• BlackBerry - video player - FramePositioningControl is null

  I'm developing a blackberry application that plays video from the server. I've used Player.start() and Player.stop() for playing and pausing a video. But I also need rewind, forward and seek bar controls in my application. I tried using FramePositioningControl for these controls. But the following code is returning null. FramePositioningControl framePositioningControl = (FramePositioningControl) player.getControl("FramePositioningControl"); I searched several forums and they say many players do not support FramePositioningControl. What players support FramePositioningControl? And what else should I do to add these controls in my application?
