  • Are there any good sites for blogging about programming?

    - by Jacques Bosch
    I have a few programming articles I would like to write, but I do not have a site of my own - yet ;). Is there a site that is specifically geared toward technical / programming topics, with great functionality and style? Or will I have to go with things like wordpress or blogspot? I would like a site that can track number of views and that has an intuitive commenting system. Any thoughts would be appreciated.

  • Rails wiki highlight/strikethrough version differences between article versions

    - by mark
    Hi I'm wondering how to implement highlighting of changes to user edited articles on a wiki style rails project. Since articles may be fairly lengthy I'd ideally like strikethrough and highlighting, similar to github and wikipedia for example. Despite searching around the net I've not really come up with much, apart from instiki which is a complete wiki application. Thanks in advance for any advice.

  • Passing variables from PHP to Javascript back to PHP using Ajax.

    - by ObjectiveJ
    I hope this makes sesne, please bare with me. So I have a PHP page that contains variables, I have some radial boxes, and on click of them, it calculates a price for the item you have clicked on. I do this by activating a js function that I have passed some variables to. Like so. PHP: <?php $result = mssql_query("SELECT * FROM Segments ORDER BY 'Squares'"); if (!$result) { echo 'query failed'; exit; } while ($row = mssql_fetch_array($result)) { ?> <span><?php echo $row["Squares"]; ?></span><input name="squares" type="radio" onclick="ajaxCases('<?php echo $row["Squares"]; ?>', '<?php echo $row["StartCaseID"]; ?>', '<?php echo $row["StartMatrixPrice"]; ?>')" value="<?php echo $row["Squares"]; ?>"<?php if ($row["Squares"] == "1") { ?> checked="checked" <?php }else{ ?> checked="" <?php } ?>/> <?php } ?> As you can see onclick it goes to a function called ajaxcases, this function looks like this. function ajaxCases(squares,start,price){ $('#step1').html('<p style="margin:100px 0px 0px 100px"><img src="images/ajax-loader-bigindic.gif" width="32" height="32" alt="" /></p>'); $('#step1').load("ajax-styles.php?squares="+squares); prevId1 = ""; document.varsForm.caseid.value=start; $('#step1price').html('<span style="margin:0px 0px 0px 30px"><img src="images/ajax-loader-price.gif" width="24" height="24" alt="" /></span>'); $('#step1price').load("ajax-step1-price.php?Squares="+Squares); return true; } This then goes to a php page called ajax-step1-price.php and I try to recall the variable Squares. However it doesn't work, I thought it was a GET however that returns undefined. In Summary: I would like to know how to pass a variable from PHP to JS then back to PHP, or if someone could just tell me where I am going wrong that would be greatly appreciated.

  • Ideal laptop specs for a Computer Science Masters student?

    - by Ayush
    I have a HP pavillion core 2 duo 2 GHz and 4 GB RAM, and it is painful to use this machine for any kind of coding. Eclipse (especially Juno) literally takes 5 minutes to load. And even after that, everything is lagy. Apart from school stuff, I also use my computer as a television. I watch Hulu, Netflix, YouTube etc in 720p, and this laptop gets hot as hell and the fans are loud enough to wake somebody up from deep sleep. I DON'T use my laptop for Gaming or Video/Photo Editing. I'm looking to buy a new laptop (in which most widely used IDEs would work smoothly and playing hi-def videos wouldn't be too much for the machine to handle) any suggestions (on hardware specs) would be greatly appreciated. Thanks

  • PHP Menu Items Count then add under more button

    - by Adrian M.
    Hello, I use the bellow code to load the main menu elements from some CMS, the present code is perfect except that it loads ALL the main items on a single line of menu - which will make the width of it unusable in any centered design (under 1000px).. I want to change this script so after 15 main elements will add a "MORE" button under which the rest of the main menu items will show as sub-items of this "MORE" button (they will not have their own sub-items as the first 15 do).. How can I do it? Thanks! <?php require_once( '../../../inc/header.inc.php' ); require_once( DIRECTORY_PATH_INC . 'membership_levels.inc.php' ); require_once( DIRECTORY_PATH_ROOT . "templates/tmpl_{$tmpl}/scripts/TemplMenu.php" ); class SimpleMenu extends TemplMenu { function getCode() { $this->iElementsCntInLine = 100; $this->getMenuInfo(); $this->genTopItems(); return $this->sCode; } function genTopItem($sText, $sLink, $sTarget, $sOnclick, $bActive, $iItemID, $isBold = false, $sPicture = '') { $sActiveStyle = ($bActive) ?

  • jquery show hidden div

    - by Fahad
    Firstly, I'm sort of embarrassed asking about this, so many people have already asked this question but even after having gone through so many posts, I'm unable to achieve what I want. Basically, a div, initially hidden, has to be displayed on a button click. I tried hiding the div using display:none and hide() and then displaying it using show(), toggle(), and css("display","block"). Using all sorts of combinations of the above, I was still unable to get the result. Code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="css/smoothness/jquery-ui-1.9.2.custom.min.css" rel="stylesheet" type="text/css" /> <script src="jQuery/jquery-1.8.3.min.js" type="text/javascript"></script> <script src="jQuery/jquery-ui-1.9.2.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#one').hide(); $('#Button1').click(function () { $('#one').toggle(500); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="one" style="height: 20px;width:200px; background-color: Red; "> </div> <asp:Button ID="Button1" runat="server" Text="Show" /> </form> </body> </html> On button click, the div is shown for a brief second before it disappears again. The same thing happens if I use show() instead of toggle() in the above code. Again the same thing if I set style="display:none" to the div instead of using hide() and then use show() or toggle(). I also tried using $('#one').css("display","block"); but again, the same result. Can anyone please tell me where I'm going wrong. Just started learning jQuery and it is really frustrating when something apparently so simple will not work. Thanks in advance. :)

  • Looking for programmer in NYC

    I have taken the idea of "language maintenance" a niche that no one is paying attention to and created a company focused on live conversation with complimentary tools. Looking to create a web 2.0 style social network with an already clearly defined brand identity, design and plan. Already have assembled a team but am looking for a passionate programmer to take the technical lead and create a functional alpha and beta.

  • powershell.exe tab completion - list alternatives?

    - by J Cooper
    I've never really used PowerShell before, and playing with it a bit, it looks like it uses cmd.exe's style of tab completion (fill in the first likely candidate, and then you can use tab to cycle through other alternatives). I'd much prefer the way e.g. bash works, where if there are multiple candidates, it shows a list of them. Is there an easy way to turn this on, by any chance?

    - by metal-gear-solid
    What are cons if we use JavaScript to apply only CSS property to that browser who do not support that property by default? to keep my HTML semantic and keep free from Deprecated HTML. Is it against content, style and Behavior separation? How much it will effect to site accessibility, usability? What are cons? If I make accessible site then should i only use whatever i can do with pure css. shouldn't use JavaScript to apply CSS properties

  • Wi-fi signal with keeping the internet cable

    - by daGrevis
    So the situation is that I have Ethernet cable which provides internet to my computer. Thing I want is to have wi-fi connection in my house and Ethernet cable (like I have before) to use for my PC. I will use wi-fi for my laptop and mobile phone. I think I need router for that and I'm looking at Asus RT-N16 (suggested in Coding Horror) for it, but I am not sure. Is it the right thing for me and I will be able to get wi-fi signal and keep the Ethernet cable? I guess the system will be that current cable goes into router, router provides wi-fi signal and gives back new cable... or something like that. Thanks in any advice! And sorry if topic isn't in right site.

  • Converting HTML TAG Object to JSON Object

    Hi, I want to convert the html tag objects to json object in the javascript in order to send them to the server from the javascript. As i have to save these objects at the Ruby on Rails server.

  • jquery ie6 issue swaping videos through hide/show while playing.

    So my code is: Click the link show the div. I'm using the jquery flash embed object. $(document).ready( function() { $('a.overview').click( function() { $('#overview').show(); // show div.contact $('#evaulting').hide(); // hide div.contact $('#his').hide(); // hide div.contact }); }); $(document).ready( function() { $('a.evaulting').click( function() { $('#evaulting').show(); // show div.contact $('#overview').hide(); // hide div.contact $('#his').hide(); // hide div.contact }); }); <div id="overview" style="display:none"> <ul> <li rel="play-norelated.swf:680:480:true:ffffff" class="flash-replaced"> <embed width="680" height="480" type="application/x-shockwave-flash" src="play-norelated.swf" pluginspage="http://www.adobe.com/go/getflashplayer" flashvars="playVideo=ent_web_480x" bgcolor="ffffff" /> <div class="alt"><h1>To Play Iron Mountain Videos - You will need to upgrade your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p></div> </li> </ul> </div> <div id="evaulting" style="display:none"> <ul> <li rel="play-norelated.swf:680:480:true:ffffff" class="flash-replaced"> <embed width="680" height="480" type="application/x-shockwave-flash" src="play-norelated.swf" pluginspage="http://www.adobe.com/go/getflashplayer" flashvars="playVideo=evaulting_web_480x" bgcolor="ffffff" /> <div class="alt"><h1>To Play Iron Mountain Video's - You will need to upgrade your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p></div> </li> </ul> </div> When I repeat this code and get the second video to load on click. It works in all browsers. The only issue I'm running into is that in IE6 the video keeps playing and in other browsers it stops the video your watching and loads the one you clicked on. I looked into using the .remove object or the .append to a div, but I can't seem to get that to work and if it does work will it play nice with IE6. Try it out and maybe solve my issues.

  • Using data from a dataset in styles with Mapnik

    - by Alex King
    I've setup Mapnik to connect to a PostGIS database, and display geometry. I'd like to have a column in my database called opacity, and use it as the opacity for that row of geometry when Mapnik renders it. So far, I've only found information on how to display text from the database, and how to use filters to display different styles when database values are within parameters. Nothing about how to use the values directly inside of a style or layer though - is this possible?
