  • How does the dispatch action call work in the Twitter sidebar

    - by phwd
    I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

    As a newbie to rails I can't find how to solve my issue ^^ I want to create a VideoPost from a form with a text field containing a video url (like youtube) I'm getting information on the video thanks to the gem https://github.com/thibaudgg/video_info And I want to save thoses information using a model of mine (VideoInformation). But I don't know how the create process should work. Thanks for any help ! I'm trying to create a VideoPost in VideoPostsController like this : def create video_info = VideoInfo.new(params[:video_url]) video_information = VideoInformation.create(video_info) #undefined method `stringify_keys' for #<Youtube:0x00000006a24120> if video_information.save @video_post = current_user.video_posts.build(video_information) end end My VideoPost model : # Table name: video_posts # # id :integer not null, primary key # user_id :integer # video_information_id :integer # created_at :datetime not null # updated_at :datetime not null My VideoInformation model (which got same attributes name than VideoInfo gem) : # Table name: video_informations # # id :integer not null, primary key # title :string(255) # description :text # keywords :text # duration :integer # video_url :string(255) # thumbnail_small :string(255) # thumbnail_large :string(255) # created_at :datetime not null # updated_at :datetime not null

  • Map a struts2 action result to a controller instead of a jsp

    - by Jim
    Hello, I'm working on on a site built using struts2. The vast majority of our targets generate xml, so mapping the result to a jsp page makes sense. A couple of our targets actually generated binaries. I'm wondering if there is a convenient way to say that the result should come from a servlet/controller instead of a jsp. Obviously this could be done by modifying the web.xml so the struts filter doesn't apply to those targets and mapping those targets as servlets, but this is non-ideal. Currently, the struts filter applies to the entire site, and we would like to keep it that way. Ideas? Thanks!

  • Can we view objets in the JVM memory?

    - by Sebastien Lorber
    Hey, At work we found that on some instances (particulary the slow ones) we have a different behaviour, acquired at the reboot. We guess a cache is not initialized correctly, or maybe a concurrency problem... Anyway it's not reproductible in any other env than production. We actually don't have loggers to activate... it's an old component... Thus i'd like to know if there are tools that can help us to see the different objets present in the JVM memory in order to check the content of the cache... Thank you!

  • Offline Database Write Cache in C#

    - by Todd Gardner
    I have a windows service that receives a large amount of data that needs to be transformed and persisted to a database. To ensure that we do not lose data, I want to create a "Write cache" for the data that will continue regardless if the database is online. Once the database becomes available again, I would want it to flush the content of the cache back into the database. I've seen some articles indicating that I might be able to do this with NHibernate, but I haven't found it conclusively. What options exist for this, and is NHibernate the appropriate direction?

  • Best approach to cache Counts from SQL tables ?

    - by pixel3cs
    I would like to develop a Forum from scratch, with special needs and customization. I would like to prepare my forum for intensive usage and wondering how to cache things like User posts count and User replies count. Having only three tables, tblForum, tblForumTopics, tblForumReplies, what is the best approach of cache the User topics and replies counts ? Think at a simple scenario: user press a link and open the Replies.aspx?id=x&page=y page, and start reading replies. On the HTTP Request, the server will run an SQL command wich will fetch all replies for that page, also "inner joining with tblForumReplies to find out the number of User replies for each user that replied." select tblForumReplies.*, tblFR.TotalReplies from tblForumReplies inner join ( select IdRepliedBy, count(*) as TotalReplies from tblForumReplies group by IdRepliedBy ) as tblFR on tblFR.IdRepliedBy = tblForumReplies.IdRepliedBy Unfortunately this approach is very cpu intensive, and I would like to see your ideas of how to cache things like table Counts. If counting replies for each user on insert/delete, and store it in a separate field, how to syncronize with manual data changing. Suppose I will manually delete Replies from SQL.

  • jQuery: if value is true without user action

    - by Kevin Brown
    I want to show a div if the value of an input =='CP'. Right now this is my code: $(".register-type").change(function(){ var value = $(this).val(); if(value == 'CP'){ $('.cp-show').show(); This works fine if they change the input, but if things get validated false and the page reloads, this input is still 'CP', but the div doesn't show... Is there a way to correct this so that jquery checks if this is set on the page load?

  • Refresh page using cache

    - by cbh
    I am trying to refresh a page, but WANT to use the cache and can't figure out how to do this. There are two situations: If I click in the URL bar and hit enter (or visit the page from somewhere else) it reloads the page/images from the cache. GREAT! If I click on the refresh button or use Javascript to refresh the page it grabs all the images again and takes forever. NOT GREAT! I've tried: top.location.reload(false); and top.location.reload(true); (I'm sending this from in an iFrame) and neither used the cache. I'm avoiding using location so it doesn't end up in the browser history twice. Question: How do I reload the page using the cached images? Is there a different javascript function or is this a mod_expires issue? Thanks for any help in advance! EDIT: (info from chrome: developer tools) When navigating to the page I get "From Cache" for all images When refreshing page I get "304 - Not Modified" for all images (and it takes the time to download each)

  • Strange "cache" effect between client and server

    - by mark
    I use a Socket-based connection between Client and server with ObjectOutputStream. The objects serialized and exchanged have this structure: public class RichiestaSalvataggioArticolo implements Serializable { private ArticoloDati articolo; public RichiestaSalvataggioArticolo(ArticoloDati articolo) { this.articolo = articolo; } @Override public void ricevi(GestoreRichieste gestore) throws Exception { gestore.interpreta(this); } public ArticoloDati getArticolo() { return articolo; } } the issue is that when I try to exchange messages between C/S with incapsulated content very similar (ArticoloDati whom differ only in 2 fields out of 10), the Client sends an ArticoloDati, but the Server receives the previous one. Does the ObjectOutputStream implement some kind of cache or memory between the calls, that fails to recognize that my 2 objects are different because they are very similar?

  • Why does code need to be reloaded in Rails 3?

    - by Venkat D.
    I am a former PHP developer learning Rails and Sinatra. In PHP, every page request loaded all of the required files. If I changed some code and refreshed the page, I could be sure that the code was fresh. In Rails 3, Controller code is fresh on every request. However, if I modify any code in the /lib folder, I need to restart the server so the changes take effect. Why does this happen? Is it something to do with the way Ruby is designed? Is Rails doing some optimizations to avoid reloading code on every request? Thanks!

  • How to check total cache size using a program

    - by user1888541
    so I'm having some trouble creating a program to measure cache size in C. I understand the basic concept of going about this but I'm still having trouble figuring out exactly what I am doing wrong. Basically, I create an array of varying length (going by power of 2s) and access each element in the array and put it in a dummy variable. I go through the array and do this around 1000 times to negate the "noise" that would otherwise occur if I only did it once to get an accurate measurement for time. Then, I look for the size that causes a big jump in access time. Unfortunately, this is where I am having my problem, I don't see this jump using my code and clearly I am doing something wrong. Another thing is that I used /proc/cpuinfo to check the cache and it said the size was 6114 but that was not a power of 2. I was told to go by powers of 2 to figure out the cache can anyone explain why this is? Here is the just of my code...I will post the rest if need be { struct timeval start; struct timeval end; // int n = 1; // change this to test different sizes int array_size = 1048576*n; // I'm trying to check the time "manually" first before creating a loop for the program to do it by itself this is why I have a separate "n" variable to increase the size char x = 0; int i =0, j=0; char *a; a =malloc(sizeof(char) * (array_size)); gettimeofday(&start,NULL); for(i=0; i<1000; i++) { for(j=0; j < array_size; j += 1) { x = a[j]; } } gettimeofday(&end,NULL); int timeTaken = (end.tv_sec * 1000000 + end.tv_usec) - (start.tv_sec *1000000 + start.tv_usec); printf("Time Taken: %d \n", timeTaken); printf("Average: %f \n", (double)timeTaken/((double)array_size); }

  • Example of xargs' -x option in action

    - by Ole Tange
    GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all. Please provide two examples in which the only difference is an added -x and that produce different output.

  • What data actually gets cached in InnoDB/MySQL?

    - by ming yeow
    Hi folks, i am trying to optimize performance for my database. My question is - what get cached in the db memory? For example: (table with 2 columns: key (indexed), data (not indexed) updated (not indexed) Select * where updated=20100202 (the db will do a scan - will the scanned rows be kept in memory?) Select * where key = 20 (the db will refer to the index - will the identified rows be kept in memory?)

  • Performing an action on Parent/Child elements independently.

    - by Matt Weldon
    I have HTML similar to the following in my page <div id="someDiv"> <img src="foo.gif" class="someImg" /> </div> The wrapper div is set up such that when it is clicked, it's background-color changes using the following jQuery code. $("div").click(function(event){ $(this).css("background-color", "blue"); }); I also have some jQuery associated with my img that will do some other function (for the sake of argument I am going to display and alert box) like so: $("img[class=someImg]").click(function(event){ alert("Image clicked"); }); The issue I have come across is that when I click on the img, the event associated with the div is also triggered. I'm pretty sure that this is due to the way that jQuery (or indeed JavaScript) is handling the two DOM elements - clicking the img would require you to also technically click the div, thus triggering both events. Two questions then really: Is my understanding of the DOM/JavaScript flawed in some way or is this actually how things are occurring? Are there any jQuery methods that would allow me to perform actions on a child element without invoking those associated with its parent?

  • Recover a deleted webpage

    - by rc
    Suppose, a blog or a nice article was hosted on a website and it got deleted or worse the website was brought down. How do you view that web page? I tried searching for the cached version in Google. But, looks like the content was deleted long ago and is not listed in the search results directly. There are annotations to the link from many other sites, but still the actual content is not fully available. Now, can anybody help me see this page... I am actually looking for http://effectize.com/become-coolest-programmer :) And, moreover, in addition to bookmarking a favorite link, is it possible to cache the content of the link as well for later reference in case it gets deleted? EDIT: Looks like a URL can be cached for future reference. Try: http://backupurl.com/

  • Problem with modifying a page with ajax, and the browser keeping the unmodified page in cache.

    - by David Lawson
    Hey there, I have a situation where my page loads some information from a database, which is then modified through AJAX. I click a link to another page, then use the 'back' button to return to the original page. The changes to the page through AJAX I made before don't appear, because the browser has the unchanged page stored in the cache. Is there a way of fixing this without setting the page not to cache at all? Thanks :)

  • Is it the filename or the whole URL used as a key in browser caches?

    - by Richard Turner
    It's common to want browsers to cache resources - JavaScript, CSS, images, etc. until there is a new version available, and then ensure that the browser fetches and caches the new version instead. One solution is to embed a version number in the resource's filename, but will placing the resources to be managed in this way in a directory with a revision number in it do the same thing? Is the whole URL to the file used as a key in the browser's cache, or is it just the filename itself and some meta-data? If my code changes from fetching '/r20/example.js' to '/r21/example.js', can I be sure that revision 20 of example.js was cached, but now revision 21 has been fetched instead and it is now cached?

  • expiring image assets referenced from stylesheets

    - by crankharder
    So rails appends timestamps to CSS, JS and image files: image_tag 'foo.png' => <img src="foo.png?123123123123' /> # or somethin like that ...which is really useful for doing far-future expiration, etc. with Apache's help. But what about images referenced from stylesheets? They don't get an appended timestamp. So it seems to me that it's entirely possible to update one of those images, redeploy, and then not see the file change because the browser doesn't think it's been updated. Unless I'm missing something. If I'm not, is there a decent solution to this problem?

  • Hibernate query cache automatically refreshed on external update?

    - by artgon
    I'm creating a service that has read-only access to the database. I have a query cache and a second level cache enabled (READ_ONLY mode) in Hibernate to speed up the service, as the tables being accessed change rarely. My question is, if someone goes into the DB and changes the tables manually (i.e. outside of Hibernate), does the cache recognize automatically that it needs to be cleared? Is there a time limit on the cache?
