  • MySQL Insert Query Randomly Takes a Long Time

    - by ShimmerTroll
    I am using MySQL to manage session data for my PHP application. When testing the app, it is usually very quick and responsive. However, seemingly randomly the response will stall before finally completing after a few seconds. I have narrowed the problem down to the session write query which looks something like this: INSERT INTO Session VALUES('lvg0p9peb1vd55tue9nvh460a7', '1275704013', '') ON DUPLICATE KEY UPDATE sessAccess='1275704013',sessData=''; The slow query log has this information: Query_time: 0.524446 Lock_time: 0.000046 Rows_sent: 0 Rows_examined: 0 This happens about 1 out of every 10 times. The query usually only takes ~0.0044 sec. The table is InnoDB with about 60 rows. sessId is the primary key with a BTREE index. Since this is accessed on every page view, it is clearly not an acceptable execution time. Why is this happening? Update: Table schema is: sessId:varchar(32), sessAccess:int(10), sessData:text

  • Use jQuery to match variable text?

    - by VUELA
    Hello! I have a sidebar navigation that lists blog entry titles down the side of the page. I am trying to write some jquery that will check the text in the title of the current full blog entry page and match it with the corresponding title in the sidebar navigation so that I can apply a class to style for an active state link ... but I'm not quite getting it! Here is the link to an example page: http://ncw-commercial.com/property-listings/eastpoint-plaza-lot.html, and below is my current code. I have also tried using :contains but could not figure out how to get that to work with a variable rather than direct text. $('.single-journal-entry-wrapper .journal-entry .title').each(function(){ var activeTitle = $(this).text(); $(".feedburnerFeedBlock .headline a").filter(function(index) { return $(this).text() == "activeTitle"; }).parent().addClass("activeTitle"); });

  • Site won't open in Facebook App for ios, nor redirect to Safari

    - by user1431811
    I'm not a heavy coder here, so i'll ask my best. We made a brochure about our home town. However users spreading it trough facebook cant open the links when in their facebook app. The app does not send it to safari either. If opened directly from safari it is no problem. The link is http://visit.lodingen360.com Is there anything i can do to the site/index.html/whatever that will make it open in safari when the link is clicked in the facebook app for ios? (that won't affect visiting the site from pc's and so on) Is there anything uiwebview won't read that can force it to safari, so that we can redirect from the thing opened in safari to the site?

  • Lua : How to check if one of the values associated with the specified key of a table is nil, from ap

    - by felace
    In lua, it's legal to do this : table={} bar if(table[key]==nil) foo However, using C API, I couldn't find way to check if there's a nil value on the specified position. lua_getglobal(L,"table"); lua_gettable(L,key); If there's a nil value stored in table[key], lua_gettable would give me the "unprotected error in call to Lua API (attempt to index a nil value)" message. Is there any way to check if there's actually something associated with that key, before actually pushing the key to do so ?

  • How do I convert a number (as a String) to an array of bytes in Java?

    - by user1795595
    I'm creating a method specific method for a java project i'm working on. The UML given specifies the return type to be of static byte[] that accepts the arguments (String, byte) So far, looks like this: public static byte[] convertNumToDigitArray(String number, byte numDigits) { } This method is supposed to convert a number (as a String) to an array of bytes. The ordering must go from most to least significant digits. For example, if the number String is “732” then index 0 of the array should contain 7. The last argument (numDigits) should match the length of the string passed in. How do I do this?

  • Dropdown menu getting hidden by images

    - by Bob
    I have a set of dropdown menus across the top of a web page. Below is text and some images. When I hover over the top of each menu the menu then expands below as expected but while it overlaps any text on the page it is hidden behind any images. I set the z-index to 9999 and the position is set to absolute. I found if I lower the opacity of the images to say 0.6 then the menu will overlap it. So one solution would be to detect when the menu is being hovered over and then in JavaScript or JQuery temporarily reduce the opacity of the rest of the page until the cursor moves off the menu. If so I'm not sure how to do that but is that the best approach?

  • /form making table go odd

    - by noryb009
    I have a table (3x3) that counts "< /form" as space in IE. The code for 1 td looks like: <style type="text/css"> table { border-width: 0px; border-collapse: collapse; padding: 0px; } td, th { padding: 0px; } </style> <table><tr><td><form name="form" action="index.php" method="post"><input type="hidden" name="from" value="a" /><input type="image" src="pic1.gif" alt="1" name="submit" value="submit" /></form></td> There is no spaces anywhere outside the tags. Inside the td, there is a form, with a hidden field and a picture. Firefox shows only the picture, but IE has spaces between the rows. I did a little debugging, and found it was from the /form. Does anyone know a fix to this?

  • advanced css: top and bottom with flexible centre

    - by Haroldo
    is it possible with just css2 to have the following: all the content to be in the flexible div.mid section overlap the top and bottom parts not fussed about ie6 here's the photoshop with centre slice: as you can see the top and bottom parts are quite large and i need to overlap them from the middle slice... Please dont misunderstand here, i understand how to make a flexible central div, the complexity is in the overlapping of the top and bottom while the mid div remains flexible. I imagine it requires either negative margins or absolutely position top and bottoms elements with z-index..

  • Best way to search a point across several polygons

    - by user1474341
    I have a requirement whereby I need to match a given point (lat,lon) against several polygons to decide if there is a match. The easiest way would be to iterative over each polygon and apply the point-in-polygon check algorithm, but that is prohibitively expensive. The next optimization that I did was to define a bounding rectangle for each polygon (upper bound, lower bound) and iteratively check the point against the bounding box (fewer comparisons as against checking all the points in the polygon). Is there any other optimization possible? Would a spatial index on the bound rectangle points or a geohash help ? Any guidance would be greatly appreciated. Thanks!

  • which one consume less resources? opening text file or make an sql query,both a thousand times ?

    - by imin
    hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

  • Clarification For Dynamic Height Boxes for CSS

    - by HollerTrain
    I am having the hardest time trying to figure out this (should be) simple css: Website is here: http://mibsoftware.us/fct/index.php I'm simply trying to get my #leftcolumn and #maincolumn to be inside the #content_container, yet whatever I'm doing isn't working at all. I'd like for the #content_container to be a dynamic height since the height of #leftcolumn and #maincolumn change depending on the page you are on. From the framework of my css it should work fine, so I must be missing something in my .css file declaring these divs. Any help would be greatly appreciated, as this will be a great learning experience for me.

  • Find and sort by number of ocurrences of tag with Active Admin and act_as_taggable_on

    - by nunopolonia
    I'm using act_as_taggable_on and Active Admin on a Rails project. In that project there are Posts and each Post has Tags. I want to show a list of Tags in Active Admin and the number of ocurrences of each one. The way I found to do this was: index do column :name column :ocurrences do |tag| ocurrences = Post.tag_counts.find(tag.id).count end default_actions end Which will search the Tag List every time for every Post, which performance wise looks really bad. I would also like to be able to sort the tags by ocurrence. Any idea of how I can do it?

  • How to get an array of all controllers in a Codeigniter project ?

    - by ashmckenzie
    I'd like to obtain a list of all controllers in a Codeiginiter project so I can easily loop through each of them and add defined routes. I can't seem to find a method that will give me what I'm after ? Here is the code snippet from the routes.php file where I would like to access the array: - // I'd like $controllers to be dynamically populated by a method // $controllers = array('pages', 'users'); // Loop through each controller and add controller/action routes // foreach ($controllers as $controller) { $route[$controller] = $controller . '/index'; $route[$controller . '/(.+)'] = $controller . '/$1'; } // Any URL that doesn't have a / in it should be tried as an action against // the pages controller // $route['([^\/]+)$'] = 'pages/$1';

  • Lua not producing table of functions (IO API)

    - by ArtOfCode
    I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

  • How can I refresh a page via jQuery and ensure that there's a connection?

    - by Steve
    Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later. I'm using the jQueryTimers plugin. this is my code so far: //reload trigger $(document).everyTime('60s', 'pagerefresh', reloadPage, 0, true); //refresh function function reloadPage() { $.ajax({ url:'index-1.php', type:'HEAD', success: location.reload(true) }) } I have no idea how to tell jQ what I want. any hint appreciated.

I would like it to appear onload automatically.. But live() does not support "load". What other ways I could get the plugin to trigger onload? hope the question is clear.
