  • IE8 is still caching my requests even with mathrandom.

    - by Ozaki
    TLDR IE is still caching my requests even with Math.random() included in the URL. So I added math random onto the end of my url: var MYKMLURL = 'http://' + host + 'data/pattern?key='+ Math.random(); I also added math random onto my function param: window.setTimeout(RefreshPatternData, 1000, MYKMLLAYER); function RefreshPatternData(layer) { layer.loaded = false; layer.setVisibility(true); layer.refresh({ force: true, params: { 'key': Math.random()} }); setTimeout(RefreshPatternData, 30000, MYKMLLAYER); } So the request appears as http://host/data/pattern?key=35678652545 etc. It changes everytime the request is made. It works in Firefox & Chrome & Safari etc. But IE8 is still caching the data and not updating my layer. Any ideas as to why this might be occuring?

  • Thread too slow. Better way to execute code (Android AndEngine)?

    - by rphello101
    I'm developing a game where the user creates sprites with every touch. I then have a thread run to check to see if those sprites collide with any others. The problem is, if I tap too quickly, I cause a null pointer exception error. I believe it's because I'm tapping faster than my thread is running. This is the thread I have: public class grow implements Runnable{ public grow(Sprite sprite){ } @Override public void run() { float radf, rads; //fill radius/stationary radius float fx=0, fy=0, sx, sy; while(down){ if(spriteC[spriteNum].active){ spriteC[spriteNum].sprite.setScale(spriteC[spriteNum].scale += 0.001); if(spriteC[spriteNum].sprite.collidesWith(ground)||spriteC[spriteNum].sprite.collidesWith(roof)|| spriteC[spriteNum].sprite.collidesWith(left)||spriteC[spriteNum].sprite.collidesWith(right)){ down = false; spriteC[spriteNum].active=false; yourScene.unregisterTouchArea(spriteC[spriteNum].sprite); } fx = spriteC[spriteNum].sprite.getX(); fy = spriteC[spriteNum].sprite.getY(); radf=spriteC[spriteNum].sprite.getHeightScaled()/2; Log.e("F"+Float.toString(fx),Float.toString(fy)); if(spriteNum>0) for(int x=0;x<spriteNum;x++){ rads=spriteC[x].sprite.getHeightScaled()/2; sx = spriteC[x].body.getWorldCenter().x * 32; sy = spriteC[x].body.getWorldCenter().y * 32; Log.e("S"+Float.toString(sx),Float.toString(sy)); Log.e(Float.toString((float) Math.sqrt(Math.pow((fx-sx),2)+Math.pow((fy-sy),2))),Float.toString((radf+rads))); if(Math.sqrt(Math.pow((fx-sx),2)+Math.pow((fy-sy),2))<(radf+rads)){ down = false; spriteC[spriteNum].active=false; yourScene.unregisterTouchArea(spriteC[spriteNum].sprite); Log.e("Collided",Boolean.toString(down)); } } } } spriteC[spriteNum].body = PhysicsFactory.createCircleBody(mPhysicsWorld, spriteC[spriteNum].sprite, BodyType.DynamicBody, FIXTURE_DEF); mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(spriteC[spriteNum].sprite, spriteC[spriteNum].body, true, true)); } } Better solution anyone? I know there is something to do with a handler, but I don't exactly know what that is or how to use one.

  • benefit of having a factory for object creation?

    - by ajsie
    I'm trying to understand the factory design pattern. I don't understand why it's good to have a middleman between the client and the product (object that the client wants). example with no factory: $mac = new Mac(); example with a factory: $appleStore = new AppleStore(); $mac = $appleStore->getProduct('mac'); How does the factory pattern decouple the client from the product? Could someone give an example of a future code change that will impact on example 1 negative, but positive in example 2 so I understand the importance of decoupling? Thanks.

  • When [script] file download fails, how can I tell why?

    - by Bruce
    My web application sends me diagnostic info from the browser javascript telling me that a [script] tag I've injected has failed to download the associated .js file. I can't reproduce this locally, and there is no particular pattern to which file fails, or what the browser type is. There is a pattern to the geo location of the requests - Mexico and Brazil are always more frequent - so I'm guessing that perhaps the internet in general is just more flaky there, and it is just network issues causing the failures. I'd really like to know for sure, though. Is there any way to determine, from the browser javascript, whether the failure occurred because of an error returned by the server, from a network error, or from a protocol timeout? I don't care if the mechanism is browser-specific, since it seems likely that the same issue is causing the error on all browser types.

  • jQuery: Scroll the window then addClass() - how to callback

    - by carillonator
    Inside a jQuery event handler, I would like to scroll the window and then add a class to something. This is my code: $('#foo').click(function() { window.scrollTo(y); $('#bar').addClass('active'); }); $(window).scroll(function() { $('#bar').removeClass('active'); }); Notice I have another handler to remove that same class whenever the window is scrolled. The scrolling part works fine, but seems to run asynchronously, so removeClass() happens after addClass() but before the scrolling is finished. I don't know how to do this in plain javascript. I know there is a jQuery scrollTop() function that does the same thing (but seems to have cross-browser issues), but it doesn't accept a callback. What I really need is a callback to add the class after the scrolling is finished. thanks!

  • Regular Expression repetition of class

    - by codersarepeople
    I am trying to figure out a regular expression for the following: <tr class="A">.*</tr><tr class="(B|C)">.*</tr> Now The second tr class will repeat an unknown number of times, with something unknown in between repetitions, but simply putting it in parentheses and added a plus doesn't work. Here's the PHP code that didn't work: $pattern = '/<tr\ class=\"A\">.*(<tr\ class=\"(B|C)\">.*<\/tr>.*)+/'; preg_match_all($pattern,$playerHtml,$scores); But it only returns the first Here's an example of something that should match: <tr class="A">blah</tr>blah <tr class="B">blah</tr>blah <tr class="B">blah</tr>blah <tr class="C">blah</tr> This only matches blahblahblah

  • MySQL -- How to do this better?

    - by Andrew
    $activeQuery = mysql_query("SELECT count(`status`) AS `active` FROM `assignments` WHERE `user` = $user_id AND `status` = 0"); $active = mysql_fetch_assoc($activeQuery); $failedQuery = mysql_query("SELECT count(`status`) AS `failed` FROM `assignments` WHERE `user` = $user_id AND `status` = 1"); $failed = mysql_fetch_assoc($failedQuery); $completedQuery = mysql_query("SELECT count(`status`) AS `completed` FROM `assignments` WHERE `user` = $user_id AND `status` = 2"); $completed = mysql_fetch_assoc($completedQuery); There has to be a better way to do that, right? I don't know how much I need to elaborate as you can see what I'm trying to do, but is there any way to do all of that in one query? I need to be able to output the active, failed, and completed assignments, preferably in one query.

  • [GWT] StackLayoutPanel and MVP

    - by Stine
    Hello! Think there might be something about this MVP approach I have completely misunderstood. Currently I am struggling to apply the MVP pattern to the part of my application consisting of a StackLayoutPanel (accordion). To me it seems natural to have a presenter and a view per stack... but how do I allow the different presenters to react when the user switch the state of the stack panel? If someone could sketch an application of the MVP pattern in the case of an accordion application I would be really, really grateful! This is really getting on my nerves! ;D Thanks a lot from Stine :)

  • [FLEX] MVC: choosing a view at runtime

    - by Alberto M
    Hi all, I'm quite new to the MVC design-pattern, and I'm translating all of my old code. I want to move to this pattern because I can change my views according to my needs, but I'm finding difficult to do it at runtime. I found an excellent example of MVC, and all that I do is the following: <mx:ViewStack xmlns:mx="http://www.adobe.com/2006/mxml" resizeToContent="true" xmlns:views="MVC.views.*"> <views:HomeView id="Home"/> <views:SecondPage id="SecondPage "/> </mx:ViewStack> what if I wanted to change (whenever the Controller says so) one of the views, for example the SecondPage view? (Hope I made my point clear)

  • Prevent RegEx Hang on Large Matches...

    - by developerjay
    This is a great regular expression for dates... However it hangs indefinitely on this one page I tried... I wanted to try this page ( http://pleac.sourceforge.net/pleac%5Fpython/datesandtimes.html ) for the fact that it does have lots of dates on it and I want to grab all of them. I don't understand why it is hanging when it doesn't on other pages... Why is my regexp hanging and/or how could I clean it up to make it better/efficient ? Python Code: monthnames = "(?:Jan\w*|Feb\w*|Mar\w*|Apr\w*|May|Jun\w?|Jul\w?|Aug\w*|Sep\w*|Oct\w*|Nov(?:ember)?|Dec\w*)" pattern1 = re.compile(r"(\d{1,4}[\/\\\-]+\d{1,2}[\/\\\-]+\d{2,4})") pattern4 = re.compile(r"(?:[\d]*[\,\.\ \-]+)*%s(?:[\,\.\ \-]+[\d]+[stndrh]*)+[:\d]*[\ ]?(PM)?(AM)?([\ \-\+\d]{4,7}|[UTCESTGMT\ ]{2,4})*"%monthnames, re.I) patterns = [pattern4, pattern1] for pattern in patterns: print re.findall(pattern, s) btw... when i say im trying it against this site..

  • PHP - ftp_get only works once

    - by William
    I'm connecting to an ftp server that I have no control over, and I'm pretty sure is using something old and outdated due to other issues I've run into. I'm simply using this code in a loop to get all the files in a directory. ftp_put($this->conn_id, $remote, $local, FTP_ASCII); The first time all goes well, but after that I get this error thrown for each file I try to get: "There is already an active transaction" I've tried both passive & active with no luck. It's the exact same code I use to connect to other FTP servers and get files with no problem. Any ideas? I suppose my last resort could be disconnecting and reconnecting for each file, but that seems like a huge waste.

  • Refactoring FAT client legacy application

    - by Paul
    I am working on a fat client legacy C++ application which has a lot of business logic mixed in with the presentation side of things. I want to clean things out and refactor the code out completely, so there is a clear seperation of concerns. I am looking at MVC or some other suitable design pattern in order to achieve this. I would like to get recommendations from people who have walked this road before - Do I use MVP or MVC (or another pattern)? What is/are the best practices for undertaking something like this (i.e. useful steps/checks) ?

  • .NET DB Query Without Allocations?

    - by Michael Covelli
    I have been given the task of re-writing some libraries written in C# so that there are no allocations once startup is completed. I just got to one project that does some DB queries over an OdbcConnection every 30 seconds. I've always just used .ExecuteReader() which creates an OdbcDataReader. Is there any pattern (like the SocketAsyncEventArgs socket pattern) that lets you re-use your own OdbcDataReader? Or some other clever way to avoid allocations? I haven't bothered to learn LINQ since all the dbs at work are Oracle based and the last I checked, there was no official Linq To Oracle provider. But if there's a way to do this in Linq, I could use one of the third-party ones.

  • proftpd, dynamic IP, and filezilla: port troubles

    - by Yami
    The basic setup: Two computers, one running proftpd, one attempting to connect via filezilla. Both linux (xubuntu on the server, kubuntu on the client). Both are at the moment behind a router on a residential (read: dynamic IP) connection; the client is a laptop I plan to take away from the home network, so I'll need this to work externally. I have my router set up to allow specific ports forwarded to each machine and, where possible, have plugged in those numbers into proftpd (via gadmin, double-checking the config file) and filezilla. Attempting to connect via active mode using the internal IP works: Status: Connecting to 192.168.1.139:8085... Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER <redacted> Response: 331 Password required for <redacted> Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PORT 192,168,1,52,153,140 Response: 200 PORT command successful Command: LIST Response: 150 Opening ASCII mode data connection for file list Response: 226 Transfer complete Status: Directory listing successful Attempting to connect via the domain name, however, leads to issues; in active mode, the PORT is the last command to be received according to the server's logs, and in passive mode, it's the PASV command. This leads me to believe I'm being redirected to a bad port? Active Sample: Status: Resolving address of <url> Status: Connecting to <ip:port> Status: Connection established, waiting for welcome message...

Response: 220 Crossroads FTP Command: USER yamikuronue Response: 331 Password required for yamikuronue Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PASV Response: 227 Entering Passive Mode (64,95,64,197,101,88). Command: LIST Error: Connection timed out Error: Failed to retrieve directory listing In both cases, the log file ends at "PORT" or "PASV" - there's no record of ever receiving a "LIST" command. Just above that I can see the attempt to connect actively via the internal IP, which does indeed include a LIST command. My config file includes "PassivePorts 20001-26999", which are the port forwards I set up for the ftp server, and "Port 8085", which is also forwarded to the same machine. I also have a MasqueradeAddress set up to prevent it from reporting its internal IP, which was an earlier issue I had. I think what I'm asking is, is there another setting someplace I have to change to get this setup to work?
