  • jQuery is only returning first item

    - by Andy
    For some strange reason, whenever I have a selector and expect to get multiple items, jQuery is only returning the first item, instead of the entire collection. This is the HTML I have: <a id="reply-424880" class="reply" href="#" rel="nofollow">Reply</a> <a id="reply-424885" class="reply" href="#" rel="nofollow">Reply</a> And the selector: $('.reply').unbind('click').click(function(event) { ... } I have tried debugging using FireBug, and still get the same results. Using the work around I can get it to work: $('a').each(function (index, element) { if ($(element).attr('class') == 'reply') { $(this).unbind('click').click(function(event) { ... }); } }); I would like to use the built-in functionality instead of my work around. Any idea why only the first element would be returned?

  • The data structure of libev watchers

    - by changchang
    Libev uses three data structures to storage different watchers. Heap: for watchers that sorted by time, such as ev_timer and ev_periodic. Linked list: such as ev_io, ev_signal, ev_child and etc. Array: such as ev_prepare, ev_check, ev_async and etc. There is no doubt about that uses heap to store timer watcher. But what is the criteria of selecting linked list and array? The data structure that stores ev_io watchers seems a little complex. It first is an array that with fd as its index and the element in the array is a linked list of ev_io watcher. It is more convenient to allocate space for array if use linked list as element. Is it the reason? Or just because of the insert or remove operation of ev_io is more frequently and the ev_prepare seems more stable? Or any other reasons?

  • Sphinx without using an auto_increment id

    - by squeeks
    I am current in planning on creating a big database (2+ million rows) with a variety of data from separate sources. I would like to avoid structuring the database around auto_increment ids to help prevent against sync issues with replication, and also because each item inserted will have a alphanumeric product code that is guaranteed to be unique - it seems to me more sense to use that instead. I am looking at a search engine to index this database with Sphinx looking rather appealing due to its design around indexing relational databases. However, looking at various tutorials and documentation seems to show database designs being dependent on an auto_increment field in one form or another and a rather bold statement in the documentation saying that document ids must be 32/64bit integers only or things break. Is there a way to have a database indexed by Sphinx without auto_increment fields as the id?

  • SQL Server - how to determine if indexes aren't being used?

    - by rwmnau
    I have a high-demand transactional database that I think is over-indexed. Originally, it didn't have any indexes at all, so adding some for common processes made a huge difference. However, over time, we've created indexes to speed up individual queries, and some of the most popular tables have 10-15 different indexes on them, and in some cases, the indexes are only slightly different from each other, or are the same columns in a different order. Is there a straightforward way to watch database activity and tell if any indexes are not hit anymore, or what their usage percentage is? I'm concerned that indexes were created to speed up either a single daily/weekly query, or even a query that's not being run anymore, but the index still has to be kept up to date every time the data changes. In the case of the high-traffic tables, that's a dozen times/second, and I want to eliminate indexes that are weighing down data updates while providing only marginal improvement.

  • php vs python django or something else for CMS module

    - by Michael
    We're looking to develop a CMS module for our website and I need some help in choosing the language/framework for this project. Basically we need to develop a "help' module like this one from ebay http://pages.ebay.com/help/index.html which will contain a lot of static pages with nice URLs for SEO. The application must run fast using low computer resources. We have been looking to use php on a custom made mvc framework but we received advice from other sources that py/django is the exactly language/framework that we need in terms of maintainability and development speed because it was developed for exactly this kind of projects so I need an expert advice on this matter with pro and cons for each choice.

  • How to place some text over the DIV without breaking hover area of this DIV?

    - by Andr
    I'm total noob with CSS and it looks like hell =/ I have absolute positioned DIV and I handle mouse events over this DIV with JS like this: <div style='position: absolute; left: 0px; width:50px; height: 50px;' onmouseover='this.style.border="2px solid red"' onmouseout='this.style.border="1px solid black"'> </div> <div style='position: absolute;'>SOME TEXT</div> I need to place some text over this DIV and over the few same DIVs, but if I place any element over this DIV onMouseOut event is firing when mouse cursor switch to text. Tag with text can't be inside the DIV. Playing with z-index didn`t help. My browser is IE8.

  • Find consecutive sub-vectors of length k out of a numeric vector which satisfy a given condition

    - by user3559153
    I have a numeric vector in R, say v= c(2,3,5,6,7,6,3,2,3,4,5,7,8,9,6,1,1,2,5,6,7,11,2,3,4). Now, I have to find all the consecutive sub-vector of size 4 out of it with the condition that each element of the sub-vector must be greater than 2 and all sub-vector must be disjoint in the sense that non of the two sub-vector can contain same index element. So my output will be: (3,5,6,7),(3,4,5,7),(5,6,7,11). [Explanation: c(2,3,5,6,7,6,3,2,3,4,5,7,8,9,6,1,3,2,5,6,7,11,2,3,4) ]

  • Lucene boost: I need to make it work better

    - by zvikico
    I'm using Lucene to index components with names and types. Some components are more important, thus, get a bigger boost. However, I cannot get my boost to work properly. I sill get some components appear later (get worse score), even though they have a higher boost. Note that the indexing is done on one field only and I've set the boost to that field alone. I'm using Lucene in Java. I don't think it has anything to do with the field length. I've seen components with the same name (but different type) get the wrong score.

  • Ruby on Rails - can't access datetime model object

    - by NomadicRiley
    I've created a model that has 3 string columns and a datetime. Everything is running in SQLite3 and I can view the records in my table just fine using Lita. I'm trying to display the values in a page (index action) using code like this: <% @details.each do |lifeCycle| % <%= debug(lifeCycle)% <%= lifeCycle.lifeCycleId % <%= lifeCycle.eventType % <%= debug(lifeCycle.timeId) % <% end % From the debug I get a result like this: --- !ruby/object:LifeCycle attributes: eventType: Order created_at: "2111359287.23037" timeId: "2455364.89983796" eventId: "98765" updated_at: "2111359287.23037" lifeCycleId: "12345" id: "1" attributes_cache: {} But whenever I try to access the event timeId - i' getting a nil value. This is true if i try to run debug on just that field debug(lifeCycle.timeId), or call a function on it. Is there something obvious I'm missing here?

  • String formatting [str.format()] with a dictionary having a key which is a str() of a number

    - by decimus phostle
    Python neophyte here. I was wondering if someone could help with the KeyError I am getting when using a dictionary for string interpolation in str.format. dictionary = {'key1': 'val1', '1': 'val2'} string1 = 'Interpolating {0[key1]}'.format(dictionary) print string1 The above works fine and yields: Interpolating val1 However doing the following: dictionary = {'key1': 'val1', '1': 'val2'} string2 = 'Interpolating {0[1]}'.format(dictionary) print string2 results in: Traceback (most recent call last): File "test.py", line 3, in <module> string2 = 'Interpolating {0[1]}'.format(dictionary) KeyError: 1L So the problem seems to be in the interpretation of the numeric key as a list index, IMHO. Is there any way to work around this? (i.e. convey that this is instead a dictionary key) TIA and apologies if this question has been asked before(couldn't find anything relevant with my search-fu).

  • python: creating a list inside a dictionary

    - by user1871081
    I just started using python and I'm trying to create a program that will read a file that looks like this: AAA x 111 AAB x 111 AAA x 112 AAC x 123 ... the file is 50 lines long and I'm trying to make the letters into keys in a dictionary and the numbers lists that correspond with the keys. I want the output to look like this: {AAA: ['111', '112'], AAB: ['111'], AAC: [123], ...} This is what I've tried file = open("filename.txt", "r") readline = file.readline().rstrip() while readline!= "": list = [] list = readline.split(" ") j = list.index("x") k = list[0:j] v = list[p + 1:] d = {} if k in d == False d[k] = [] d[k].append(v) else d[k].append(v) readline = file.readline().rstrip() I keep getting syntax errors on my if statement and I can't figure out what I've done wrong.

  • Using preg_match as boolean AND array

    - by silow
    I have this code where preg_match is used to break up a string into $pmarr array. Index 1 of that array is then being used to set a value $val = $pmarr[1]. $pmarr = array(); if (preg_match($expression, $orig, $pmarr)) { $val = $pmarr[1]; } What I'm wondering about is why the preg_match itself is being used as a boolean. If the expression doesn't match, does the array stay empty and therefore equate to false? Is the above code the same as saying preg_match($expression, $orig, $pmarr); if(isset($pmarr[1]) AND !empty($pmarr[1])){ $val = $pmarr[1]; }

  • Is it possible to get the current request that is being served by node.js?

    - by user420504
    I am using express.js. I have a need to be able to log certain request data whenever someone tries to log a message. For this I would like to create a helper method like so function log_message(level, message){ winston.log(level, req.path + "" + message); } I would then use the method like so. exports.index = function(req, res){ log_message("info", "I'm here"); } Note that I am not passing the req object to the log_message function. I want that to be transparently done so that the log_message API user does not need to be aware of the common data that is being logged. Is there a way to achieve this with express.js/node.js. Is the request object available from a global variable of some sort?

  • How do I gather a class' css attributes given nothing but the className?

    For example I might have some css stuff that looks like this: .divType1 { position: absolute; width: 60px; height: 60px; left: 400px; top: 100px; border: 1px solid #89B; z-index: 0; } Now within Javascript I want to gather div class divType1' css attributes, but am provided only with the div class, so I can't do something of form ( pseudo-code ): selectDivWithClass( divType1 ).getCss(left). I could hack something by instantiating a div with class divType1 and grab its css attributes, and then destroy it, but is there a better way?

  • Paginator (Migration from Cake 1.3 to 2.0

    - by Christian Waschke
    i am struggling with the paginator in cakephp 2.0. While i am trying to migrate my application to 2.0 i cant find any solution to jump directly to the last page. In 1.3 it was quiet to do that from outside like this: echo $this->Html->link(__('Flights'), array('controller' => 'flights', 'action' => 'index','page' => 'last')); but this little trick putting 'page:last' in does not work anymore in 2.0. Of course there is a Paginator function called last, but this would only help if i would be already inside the app. My Problem is to access from an outside link directly the last page of the paginator. Thank you for reading, cdjw

  • (Rails) How do I reference resources from non-restful views...?

    - by humble_coder
    Hi All, How do you ensure that your javascript includes get included properly for all files everywhere using a particular layout? Basically I have some non-restful actions that I've added. I haven't added any ROUTES for them, however, using normal text rendering works fine. It's when I start requiring different "swf" and "js" files (files which are properly placed in PUBLIC) that things get hairy. I start receiving "406 Not Acceptable" errors telling me that it's looking for the files in a subdirectory of the current controller. As it stands I'm in including the JS in "application" layout file. It works for the INDEX action, but doesn't seem to work for any of the non-restful actions. Thoughts?

  • SQL Server FTS: possible to get information how/why rows were matched?

    - by jimmy_keen
    Is it possible to get the information why/how given row returned by FTS query was matched (or which substring caused row to match)? For example, consider simpliest table with id and text columns, with FTS index on the later one. SELECT * FROM Example WHERE CONTAINS(text, 'FORMSOF(INFLECTIONAL, jump)'); This examplary query could return, say row {1, 'Jumping Jack'}. Now, is it possible to somehow get information that this very row was matched because of 'Jumping' word? It doesn't even have to be exact information, more of a which substring caused row to match. Why I'm asking - I got C# app that builds up those queries basing on user input (keywords to search for), and I need the very basic information why/how row was matched back, to use further in C# code. If it's not possible, any alternatives?
