  • Why isn't this button firing the anchor tag?

    - by Noor
    My idea is to press a button that takes me to a web page. I've created a thing that dynamically creates a button and an anchor tag. When the button is clicked, I want it to "click"/fire up the anchor tag.. I've uploaded a demo to my site, when you try it out just leave everything as it is. Click the first button then the add button right away.. then try to click the dynamically created button. Nothing happens, but if you watch the source you can find an anchor tag with the ID FL1000, I've set it up so that the anchor tag gets the ID from the value of the created button + 1000 just incase I need to use that ID.. Thanks guys... edit: this is optimized for google chrome, haven't tried it out with other browser.

  • MySQL TEXT field performance

    - by Jonathon
    I have several TEXT and/or MEDIUMTEXT fields in each of our 1000 MySQL tables. I now know that TEXT fields are written to disk rather than in memory when queried. Is that also true even if that field is not called in the query? For example, if I have a table (tbExam) with 2 fields (id int(11) and comment text) and I run SELECT id FROM tbExam, does MySQL still have to write that to disk before returning results or will it run that query in memory? I am trying to figure out if I need to reconfigure our actual db tables to switch to varchar(xxxx) or keep the text fields and reconfigure the queries.

  • jQuery accordion: is there a way to make the scrollbar fit the displayed panel?

    - by Cheeso
    I have a jQuery accordion (jQuery 1.3.2, jQuery UI 1.7.2), with between 3-12 content panels. Some of the content panels are large, and have lots of content. some are small, and have only a little. When I expand any of them, the scrollbar on the div containing the accordion (it's got css overflow: auto;) is set as if the largest of the panels is expanded. Let's say I have 3 panels. One has 3 lines of content, one has 20 lines, and one has 1000 lines. If I expand either of the first two, the scrollbar indicator gets very very tiny, and moves all the way to the top, even though there is nothing worth scrolling. Is there a way to fix this? It seems like autoHeight:false ought to do it, but that doesn't work for me.

  • Programmatically determine the relative "popularities" of a list of items (books, songs, movies, etc

    - by Horace Loeb
    Given a list of (say) songs, what's the best way to determine their relative "popularity"? My first thought is to use Google Trends. This list of songs: Subterranean Homesick Blues Empire State of Mind California Gurls produces the following Google Trends report: (to find out what's popular now, I restricted the report to the last 30 days) Empire State of Mind is marginally more popular than California Gurls, and Subterranean Homesick Blues is far less popular than either. So this works pretty well, but what happens when your list is 100 or 1000 songs long? Google Trends only allows you to compare 5 terms at once, so absent a huge round-robin, what's the right approach? Another option is to just do a Google Search for each song and see which has the most results, but this doesn't really measure the same thing

  • reuse generators

    - by wiso
    I need to check the central limit with dices. Rool D dices. Sum the results. Repeat the same thing for N times. Change D and repeat. There's no need to store random values so I want to use only generators. The problem is that generators are consuming, I can't resuging them more times. Now my code use explicit for and I don't like it. dice_numbers = (1, 2, 10, 100, 1000) repetitions = 10000 for dice_number in dice_numbers: # how many dice to sum sum_container = [] for r in range(repetitions): rool_sum = sum((random.randint(1,6) for _ in range(dice_number))) sum_container.append(rool_sum) plot_histogram(sum_container) I want to create something like for r in repetitions: rools_generator = (random.randint(1,6) for _ in range(dice_number) sum_generator = (sum(rools_generator) for _ in range(r)) but the second time I resuse rools_generator it is condumed. I need to construct generator class?

  • Perform tasks with delay, without delaying web response (ASP.NET)

    - by Tomas Lycken
    I'm working on a feature that needs to send two text messages with a 30 second delay, and it is crucial that both text messages are sent. Currently, this feature is built with ajax requests, that are sent with a 30 second javascript delay, but since this requires the user to have his browser open and left on the same page for at least 30 seconds, it is not a method I like. Instead, I have tried to solve this with threading. This is what I've done: Public Shared Sub Larma() Dim thread As New System.Threading.Thread(AddressOf Larma_Thread) thread.Start() End Sub Private Shared Sub Larma_Thread() StartaLarm() Thread.Sleep(1000 * 30) StoppaLarm() End Sub A web handler calls Larma(), and StartaLarm() and StoppaLarm() are the methods that send the first and second text messages respectively. However, I only get the first text message delivered - the second is never sent. Am I doing something wrong here? I have no deep understanding of how threading works in ASP.NET, so please let me know how to accomplish this.

So in the above mentioned case the number 25.562. Is this possible with grep and regular expressions? Thanks for your help.

  • Optimal strategy to make a C++ hash table, thread safe

    - by Ajeet
    (I am interested in design of implementation NOT a readymade construct that will do it all.) Suppose we have a class HashTable (not hash-map implemented as a tree but hash-table) and say there are eight threads. Suppose read to write ratio is about 100:1 or even better 1000:1. Case A) Only one thread is a writer and others including writer can read from HashTable(they may simply iterate over entire hash table) Case B) All threads are identical and all could read/write. Can someone suggest best strategy to make the class thread safe with following consideration 1. Top priority to least lock contention 2. Second priority to least number of locks My understanding so far is thus : One BIG reader-writer lock(semaphore). Specialize the semaphore so that there could be eight instances writer-resource for case B, where each each writer resource locks one row(or range for that matter). (so i guess 1+8 mutexes) Please let me know if I am thinking on the correct line, and how could we improve on this solution.

  • C# chart control Performance with large amounts of data

    - by user3642115
    I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series. The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down. Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues. Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens. Thanks.

  • Check for changes with jquery and a database

    - by Steve
    I am doing a notification system. When a new post is published, users will be notified immediately by an small notification on the screen. I am currently using this: setInterval(function(){ checkForChanges(); }, 2*1000); function checkForChanges(){ $.post("http://"+ document.domain + "/posts/checkForChanges/", function(dat){ if(dat>0){ .... /*create notification*/ } }); } And i was wondering if this is the correct way to do it or not. Because, this is calling a PHP function every 2 seconds and making a query to the database. In case there are no new changes, it won't do anything... Thanks.

  • Android Timer update UI between multiple tasks

    - by Rilcon42
    I have tried multiple ways to have a single persistent timer update the ui in multiple activities, and nothing seems to work. I have tried an AsyncTask, a Handler, and a CountDownTimer. The code below does not execute the first Log.i statement.... Is there a better way to start the timer (which must be called from another class) in Main (which is the only persistent class)? public static void MainLawTimer() { MainActivity.lawTimer = new CountDownTimer(MainActivity.timeLeft, 1000) { public void onTick(long millisUntilFinished) { Log.i("aaa","Timer running. Time left: "+MainActivity.timeLeft); MainActivity.timeLeft--; if(MainActivity.timeLeft<=0) { //do stuff } else { //call method in another class } }

  • Programmatic gradient stops with Javascript

    - by TomcatExodus
    Working with Javascript (jQuery), given 2 color values (2033ff and 3300a0 for example) how can I determine certain gradient stops between them? Reason being is, I intend on using an array of color values: 0 => '000000' 8400 => 'f0ff00' 44000 => '2033ff' 68400 => '3300a0' There being 86400 seconds in a day, 12:00AM maps to 0, and 11:59PM maps to 86399. As time passes, the background color of a specified element changes to the appropriate color in gradient list via window.setInterval(function(e){ ... }, 1000). For example 2:32:11PM = 52331, which from the example would be somewhere between 2033ff and 3300a0. I don't need to populate the array with the values (unless that would be easier) but instead use the index and value as references.
