  • Architecture for a farmville/yoville/cafe world type game?

    - by Joff
    I'm thinking of building a game along the lines of Farmville - items, events, time management system etc. Options I am thinking of: 1) Flash UI frontend that uses AMFPHP to get all data for the view from a PHP powered backend. 2) Actionscript to power the whole game Any input is appreciated. My concern with Actionscript is scaling, my concern with PHP is having to build an update system that would need a lot of back and forth xmlhttprequests which might get complicated. If there's a better way to build something like this, I'm all ears :)

  • Wi-Fi connected but can't go to any site

    - by Michael Dy
    My Windows 7 laptop can connect to our Wi-Fi signal, I can sign in on Yahoo! Messenger, but I can't go to any site. I can access the Net on other devices. The issue started a few weeks ago, so I've been troubleshooting since then in vain. There's no virus, and I already used System Restore. In Wireless Network Connection Status, the received activity is greater than the sent activity. I turned off Windows Firewall and still no Net access. My ping tests: How do I fix this?

  • Huge email sizes when using mail merge in Word 2010

    - by Nic
    So I've designed an HTML template to send out some emails on. The code is fine, everything looks great there, and it tests just fantastically. I was sending out putting my recipients in the BCC field, but I decided to make it a little more personal and open the file in Word and do an email merge. The HTML file itself is 3.06kb and contains an img src to an absolute URL, which is about 125kb (a little large, I know, but it's very important). When I merge the file from Word 2010 - Outlook 2010, the email size jumps to about 250kb. It's not much, I know, but I'm a gigantic nerd and I'm stuck thinking it should be about 5kb with MIME overhead. Here's the file list on one of the test emails: File Size image001.png 104366 image002.gif 43 MESSAGE 1259 Mime.822 152575 TEXT.htm 5712 Since the img src is specified, I'm not sure why these are coming through. If this is an issue inherent to Outlook, I'd be happy to explore other options.

  • How to make the WebBrowser to scroll up when new content is appended to the bottom of the page?

    - by Java Doe
    In order to achieve this effect, I would like to know how I can make the WebBrowser to scroll up when new content is added to the HTML page? "Allow more entries to be displayed in the view: When the user clicks more, additional entries should be displayed in addition to the ones which are already displayed. The code should cause the UI to scroll such that the first entry of the "more" set is on top". I am using com.ibm.rcp.browser.service.WebBrowser which is similar to SWT WebBrowser.

  • Why do .NET winforms scale improperly at large DPI settings?

    - by Alex
    My .NET application (VB.NET 3.5 if you really must know) forms do not properly format when rendered at high DPI settings. All of the fixes I've found so far simply explain the cause of the problem as "certain UI elements do not scale properly". I was wondering if anyone had a more meaningful explanation? Thanks!

  • Simple Grouping With TableSorter Plugin

    - by HurnsMobile
    Im playing around with the Tablesorter plug-in for jQuery and was trying to get a very simple grouping functionality added into it. Using the follow html/js works great until you click sort again and reverse the order. The headers get moved to the bottom of the group when this happens. The following is my (admitedly hacky) attempt at it. Does anyone have any ideas? <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Table Manipulation Test</title> <link type="text/css" href="css/ui-lightness/jquery-ui-1.8.1.custom.css" rel="stylesheet" /> <link rel="stylesheet" href="tablesorter/themes/green/style.css" type="text/css"/> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="js/jquery-ui-1.8.1.custom.min.js"></script> <script type="text/javascript" src="tablesorter/jquery.tablesorter.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#test_table").tablesorter({ sortForce: [[3,0]] }); $(".group_details").hide(); $(".group_header").click(function(){ var group = $(this).attr("group"); var $expander = $(this).children("td.expanderguy") if ($("." + group + ":visible").length){ $("." + group + "").fadeOut('fast'); $expander.html("<img src='icons/plus.gif'>"); } else{ $("." + group + "").fadeIn('fast'); $expander.html("<img src='icons/minus.gif'>"); } }); } ); </script> <style type="text/css"> .group_header td{ background-color: #888888; !important } </style> </head> <body> <table id="test_table" class="tablesorter"> <thead> <tr><th>First Name</th><th>Last Name</th><th>Email</th><th>Due Date</th><th>Amount Due</th></tr> </thead> <tbody> <tr class="group_header" group="group1"><td class="expanderguy"><img src="icons/plus.gif"></td><td></td><td></td><td>Monday, June 7</td><td></td></tr> <tr class="group_details group1"><td>Flavian</td><td>Wenceslas</td><td>[email protected]</td><td>Monday, June 7</td><td>$100</td></tr> <tr class="group_details group1"><td>Gordian</td><td>Ives</td><td>[email protected]</td><td>Monday, June 7</td><td>$1700</td></tr> <tr class="group_details group1"><td>Saladin</td><td>Tarquin</td><td>[email protected]</td><td>Monday, June 7</td><td>$1700</td></tr> <tr class="group_details group1"><td>Urban</td><td>Cyprian</td><td>[email protected]</td><td>Monday, June 7</td><td>$1500</td></tr> <tr class="group_details group1"><td>Sargon</td><td>Swithun</td><td>[email protected]</td><td>Monday, June 7</td><td>$1100</td></tr> <tr class="group_details group1"><td>Pompey</td><td>Ladislas</td><td>[email protected]</td><td>Monday, June 7</td><td>$300</td></tr> <tr class="group_details group1"><td>Attila</td><td>Hiawatha</td><td>[email protected]</td><td>Monday, June 7</td><td>$200</td></tr> <tr class="group_header" group="group2"><td class="expanderguy"><img src="icons/plus.gif"></td><td></td><td></td><td>Tuesday, June 8</td><td></td></tr> <tr class="group_details group2"><td>Bruce</td><td>Fenton</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$1700</td></tr> <tr class="group_details group2"><td>Wade</td><td>Sequoia</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$1400</td></tr> <tr class="group_details group2"><td>Eddie</td><td>Jerold</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$1100</td></tr> <tr class="group_details group2"><td>Lynn</td><td>Lucan</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$1200</td></tr> <tr class="group_details group2"><td>Taegan</td><td>Tadg</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$100</td></tr> <tr class="group_details group2"><td>Clyde</td><td>Reed</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$6100</td></tr> <tr class="group_details group2"><td>Alaois</td><td>Art</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$2100</td></tr> <tr class="group_details group2"><td>Gilbert</td><td>Patsy</td><td>[email protected]</td><td>Tuesday, June 8</td><td>$1500</td></tr> <tr class="group_header" group="group3"><td class="expanderguy"><img src="icons/plus.gif"></td><td></td><td></td><td>Wednesday, June 9</td><td></td></tr> <tr class="group_details group3" ><td>Clem</td><td>Eben</td><td>[email protected]</td><td>Wednesday, June 9</td><td>$2100</td></tr> <tr class="group_details group3" ><td>Elijah</td><td>Julyan</td><td>[email protected]</td><td>Wednesday, June 9</td><td>$2100</td></tr> <tr class="group_details group3" ><td>Marvyn</td><td>Damian</td><td>[email protected]</td><td>Wednesday, June 9</td><td>$1100</td></tr> <tr class="group_details group3" ><td>Sawyer</td><td>Ryker</td><td>[email protected]</td><td>Wednesday, June 9</td><td>$500</td></tr> </tbody> </table> </body>

  • Add querystring parameters to link_to

    - by Craig
    I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

  • Facebook Connect for iPhone: How to upload an image (UIImage) to user's wall without having to use j

    - by Crowem
    Is there any way to upload an image (UIImage) directly from an iPhone app to a user's wall/feed? All the samples I see are either using a json-embedded link or they use the photos.upload call with album ID (aid) which results in the user getting the image in his photo album(s). What I want to do is to upload an (UI)Image created (by the user) inside an iPhone app and upload to his/her wall. Is this possible? Sample code would be highly appreciated.

    - by Benny
    For a long operation that will be executed in presenter, where to set the wait cursor? in View? the view shouldn't know too much about business logic, it is passive. in presenter? seems odd in presenter to call UI code. add method to View interface, like SetWait(bool), and call it in presenter? So what do you think?

  • The meaning of thermal throttle counters and package power limit notifications in Linux

    - by Trustin Lee
    Whenever I do some performance testing on my Linux-installed MacBook Pro, I often see the following messages in dmesg: Aug 8 09:29:31 infinity kernel: [79791.789404] CPU1: Package power limit notification (total events = 40365) Aug 8 09:29:31 infinity kernel: [79791.789408] CPU3: Package power limit notification (total events = 40367) Aug 8 09:29:31 infinity kernel: [79791.789411] CPU2: Package power limit notification (total events = 40453) Aug 8 09:29:31 infinity kernel: [79791.789414] CPU0: Package power limit notification (total events = 40453) I also see the throttle counters in the sysfs increases over time: trustin@infinity:/sys/devices/system/cpu/cpu0/thermal_throttle $ ls core_power_limit_count package_power_limit_count core_throttle_count package_throttle_count $ cat core_power_limit_count 0 $ cat core_throttle_count 41912 $ cat package_power_limit_count 67945 $ cat package_throttle_count 67565 What do these counters mean? Do they affect the performance of CPU or system? Do they result in increased deviation of performance numbers? (i.e. Do they prevent me from getting reliable performance numbers?) If so, how do I avoid these messages and increasing counters? Would running the performance tests on a well-cooled desktop system help?

  • What happens when Oracle's Enterprise Single-Sign-On database goes down? [migrated]

    - by Unai
    We're working on setting up Oracle's Enterprise Single-Sign-On with High Availability. At the moment every component provides HA except our database backend (i.e. we have just one instance). While conducting some kick-the-plug tests we learnt that the ESSO system works even with the database turned OFF. This was a nice surprise but now we need to understand what are the implications of a database failure; sure the sessions might be handled on the application servers and the policies might have been cached but... for how long? how big is this cache? what is the role of the database? I would appreciate if anyone shares her/his experience and/or points out to documentation that covers this. Thank you so much.

  • ssh port forwarding / security risk

    - by jcooper
    Hi there, I want to access a web application running on a web server behind my office firewall from an external machine. We have a bastion host running sshd that is accessible from the Internet. I want to know if this solution is a bad idea: Create an account on the bastion host with shell=/bin/false and no password ('testuser') Create a ssh RSA key on the external machine Add the public RSA key to the testuser's authorized_keys file ssh to the bastion host from the external host using: ssh -N 8888:targethost:80 run my tests from the external host shut down the ssh tunnel I understand that if my RSA private key were compromised then someone could ssh to the bastion host. But are there other reasons this solution is a bad idea? thank you!
