  • When Should I Use Threads?

    - by cam
    As far as I'm concerned, the ideal amount of threads is 3: one for the UI, one for CPU resources, and one for IO resources. But I'm probably wrong. I'm just getting introduced to them, but I've always used one for the UI and one for everything else. When should I use threads and how? How do I know if I should be using them?

  • How can I get a COUNT(col) ... GROUP BY to use an index?

    - by thecoop
    I've got a table (col1, col2, ...) with an index on (col1, col2, ...). The table has got millions of rows in it, and I want to run a query: SELECT col1, COUNT(col2) WHERE col1 NOT IN (<couple of exclusions>) GROUP BY col1 Unfortunately, this is resulting in a full table scan of the table, which takes upwards of a minute. Is there any way of getting oracle to use the index on the columns to return the results much faster?

  • Faster way to dump mysql

    - by japancheese
    This may be a dumb question, but I was just watching a screencast on MySQL replication, and I learned that a master database doesn't send SQL over to a slave for replication, it actually sends data over in binary, which makes importing extremely fast. I started wondering, "if a database can export and import binary, why do mysqldumps / imports take so long?" Is there a way to get mysql to dump a database in binary in a similar fashion to speed up that process as well?

  • JQuery UI: is it possible to know where an object has been dropped?

    - by Jack Duluoz
    Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

  • Extract Data from a Website using PHP

    - by 01jayss
    I am trying to get PHP to extract the TOKEN (the uppercase one), USERID (uppercase), and the USER NAME (uppercase) from a web page with the following text. {"rsp":{"stat":"ok","auth":{"token":"**TOKEN**","perms":"read","user":{"id":"**USERID**","username":"**USER NAME**","fullname":"**NAME OF USER**"}}}} (This is from the RTM api, getting the authentication token of the user). How would I go about doing this? Thanks!

  • Selecting id of TextArea (despite RichEditableText)

    - by duder
    I'm trying to select the id of a textArea when it's focused in <s:TextArea id="textarea1" focusIn="selectId(event)" /> selectId(event){ event.target.id; } Problem is TextArea is made up of RichEditableText so target doesn't actually refer to TextArea. I've tried event.target.parent.id but still not getting there. Anyone knows how to get to the bottom of this?

Any help is much appreciated :)

  • Java- screen capture behind the application.

    - by Auxiliary
    Is there a way to capture the screen but without the app itself getting shown. I know how to minimize or make a frame invisible but this has to be done real fast cos it's going to happen alot in each second (at least once every second). I want it to look something like the magnifier in Windows Vista/7. (The app can see behind itself.) Thanks in advance.
