  • PHP thread pool?

    - by embedded
    I have scheduled a CRON job to run every 4 hours which needs to gather user accounts information. Now I want to speed things up and to split the work between several processes and to use one process to update the MySQL DB with the retrieved data from other processes. In JAVA I know that there is a thread pool which I can dedicate some threads to accomplish some work. how do I do it in PHP? Any advice is welcome. Thank

  • WPF / Silverlight - Mapping API

    - by Travis
    I am about to start on a project where I need to display maps with cross streets and possibly directions. I know there are a lot of API for the web, but I was wondering what the best solution is for a desktop application. I know of Bing Maps and I believe there are some Google Maps solutions out there as well. Any help or information on good mapping API's would be greatly appreciated. Thanks.

  • Objective-C memory management issue

    - by Toby Wilson
    I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which adds web service call information to a stack. A seperate thread takes the most recent web service call information from the stack, and uses it to make the web service call. The other objects on the stack get binned. The idea of this is to reduce the number of web service calls to only those appropriate, and only one at a time. Right, with the long story out of the way (for which I apologise), here is my memory management problem: The graph has persistant (and suitably locked) NSDate* objects for the currently displayed start & end times of the graph. These are passed into the initialisers for my web service request objects. The web service call objects then retain the dates. After the web service calls have been made (or binned if they were out of date), they release the NSDate*. The graph itself releases and reallocates new NSDates* on the 'touches ended' event. If there is only one web service call object on the stack when removeAllObjects is called, EXC_BAD_ACCESS occurs in the web service call object's deallocation method when it attempts to release the date objects (even though they appear to exist and are in scope in the debugger). If, however, I comment out the release messages from the destructor, no memory leak occurs for one object on the stack being released, but memory leaks occur if there are more than one object on the stack. I have absolutely no idea what is going wrong. It doesn't make a difference what storage symantics I use for the web service call objects dates as they are assigned in the initialiser and then only read (so for correctness' sake are set to readonly). It also doesn't seem to make a difference if I retain or copy the dates in the initialiser (though anything else obviously falls out of scope or is unwantedly released elsewhere and causes a crash). I'm sorry this explanation is long winded, I hope it's sufficiently clear but I'm not gambling on that either I'm afraid. Major big thanks to anyone that can help, even suggest anything I may have missed?

  • What is the most semantic way to display a street address in HTML?

    - by tomk
    I have an address that is going to be displayed on a webpage, but it is not the address for the author of the page. How should this be coded to be semantic given the w3c recommendation of: The ADDRESS element may be used by authors to supply contact information for a document or a major part of a document such as a form. This element often appears at the beginning or end of a document.

  • Centering fonts in VB6

    - by James Musser
    How do you determine the length of a string of text in Arial Bold font, and then center it in VB6? If not here, can you point me in a direction where I might be able to find this information? We're not using a "label" or "picture box" do print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.

  • How do I find where an exception was thrown in C++?

    - by Alex
    I have a program that throws an uncaught exception somewhere. All I get is a report of an exception being thrown, and no information as to where it was thrown. It seems illogical for a program compiled to contain debug symbols not to notify me of where in my code an exception was generated. Is there any way to tell where my exceptions are coming from short of setting 'catch throw' in gdb and calling a backtrace for every single thrown exception?

  • Grabbing "last saved by" metadata from access '03 file to excel '03 in VBA

    - by Spacious
    So I am in Excel trying to read the last saved metadata from an Access database, but I cannot figure out how on earth to do this. If I use environ$("username") it will give my the last saved information for the excel document where I am coding, not the access db that I want it to grab from. Excel has a built in function for grabbing username data, but I cannot find one for access. How can I do this?! Any help is greatly appreciated!

    I've looked through the YouTube JS API, but can't find a way to jump to a video in a playlist. (Mimicking the built-in navigation) And if you're wondering why I'd want both, it's because I have a menu set up with additional information, and want to let the user click these links to jump between the videos.

    - by 8EM
    What is the best way to update a Java or GWT program from MySQL. For example, a MySQL database which holds Weather information... updating whenever the weather changes a degree. How would I update a Java / GWT field with each update. Would I use a thread to query every few seconds??

  • What to have in mind when building a AJAX-based webapp

    - by Industrial
    Hi everyone, We're in the first steps of what will be a AJAX-based webapp where information and generated HTML will be sent backwards and forwards with the help of JSON/POST techniques. We're able to get the data out quickly without putting to much load on the database with the help of a cache-layer that features memcached as well as disc-based cache. Besides that - what's essential to have in mind when designing AJAX heavy webapps? Thanks a lot,
