  • Computer Locked after period of time

    - by bossDub
    I have a Windows XP machine that locks itself after an unknown amount of time. I have disabled the screen saver completely, and unchecked "lock computer when coming out of standby". I've even overrode the settings with gpedit. Even still, it locks itself after a while, and it doesn't take long. If it's any sort of hint, the time period for the screensaver is greyed out, even if I choose an actual screensaver.

  • Django - raw_id_fields title not refreshing.

    - by James Howell
    Hi, I am currently having an issue when using the raw_id_field within admin.py in my Django project. My site's admin area has a number of image upload fields for various different model pages which are all ForeignKey fields to an Image model where all images for the site are stored. As the site will eventually be dealing with a large quantity of images (100s, maybe 1000s) the default select box would be unusable. I created various admin.ModelAdmin classes e.g class InfoSlideAdmin(admin.ModelAdmin): raw_id_fields=('image',) These change the image selector within my Edit pages from a Select Box to a Raw ID Field. However when I select a different image using this control although the ID of the new image is shown the title from the previous image still displays. Any ideas?

  • Configure Postfix to allow incoming mails only from one (defined) mail-id

    - by Saurabh
    I have set-up Postfix with Spamassassin on Ubuntu 12.04.5. Fundamental usage of Postfix is to (pipe) trigger a PHP file. Till here I've arrived successfully. Now, to avoid unneccessary load on the server, and also to avoid unwanted mails triggering my PHP script, I want to configure Postfix to allow mails only from [email protected] and reject everything else. How to achieve this absolute lock-down on mail server unless mail comes from [email protected]?

  • How to deal with large result sets with Linq to Entities?

    - by user169867
    I have a fairly complex linq to entities query that I display on a website. It uses paging so I never pull down more than 50 records at a time for display. But I also want to give the user the option to export the full results to Excel or some other file format. My concern is that there could potentially be a large # of records all being loaded into memory at one time to do this. Is there a way to process a linq result set 1 record at a time like you could w/ a datareader so only 1 record is really being kept in memory at a time? I'd appreciate any help. Thanks

  • Redirecting a large number of URLs with htaccess or php header

    - by Peter
    I have undergone a major website overhaul and now have 5,000+ incoming links from search engines and external sites, bookmark services etc that lead to dead pages or 404 errors. A lot of the pages have corresponding "permalinks" or known replacement hierarchy/URL structure. I've started to list the main redirects with htaccess or physical files with simply a header location reidrect which is clearly not sustainable! What would be the best method to list all of the old link addresses and their corresponding new addresses with htaccess, php headers, mysql, sitemap file or is it better to have all broken links and wait for search engines etc to re-index my site? Are there any implications for having a large number of redirecting files for this temporary period until links are reset?

  • PHP Fatal error on line number that doesn't exist

    - by alexantd
    Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in /Library/WebServer/Documents/XMLDataStore.class.php on line 981 The curious thing about this error is not the memory leak, which would be easy enough to troubleshoot. Rather, it is the fact that XMLDataStore.class.php is only 850 lines long, which I have verified in multiple text editors. This is with the PHP 5.3 bundled with Snow Leopard. I'm not using an opcode cache. Here is my php.ini: allow_url_fopen = Off error_reporting = -1 display_errors = 1 display_startup_errors = 1 date.timezone = 'America/Los_Angeles' output_buffering = Off realpath_cache_size = 0k XMLDataStore.class.php has recently been refactored and it used to be longer than 981 lines. It's almost as if PHP has cached a 2-week-old version and is reading that. I'm positive that the current version at /Library/WebServer/Documents/XMLDataStore.class.php is only 850 lines long, though.

  • Switching from C++ (with a lot of STL use) to C for interpreter building

    - by wndsr
    I'm switching from C++ to C because I'm rebuilding my toy interpreter. I was used to vectors for dynamic allocation of objects like tokens or instructions of my programs, stacks and mainly strings with all their aspects. Now, in C I'm not going to have all these anymore. I know that I will have to use a lot of memory management, too. I'm completely new to C, I only know the high-level easy-life data structures from the STL, how can I get started with strings and dynamic memory allocation?

  • jquery $.GET loading order

    - by welovedesign
    I am loading all external pages in jquery for a slider. The problem is it loads in a different order. What I need to do is sequence the loading of pages $.get("page1.php", function( my_var ) { $('#slider').append($('.content', my_var)); }); $.get("page2.php", function( my_var ) { $('#slider').append($('.content', my_var)); }); $.get("page3.php", function( my_var ) { $('#slider').append($('.content', my_var)); }); sometimes page3 loads before page2.

  • Creating a virtual, data-driven section of a Wordpress-powered site

    - by lgomez
    Hello all, I want to create a plugin for wordpress to automatically serve pages containing data pulled from a provider's API. The API returns one or more records containing data for that record and I simply want to have the plugin intercept the request, call the API with parameters pulled from the request URI and display the data using a template that I can either let them upload to the server or let them copy and paste into the plugins admin settings. For example, I may want one of my wordpress installations to show products pulled from such an API under the url "example.com/products". The plugin would catch that request, extract the variables from the URL, call the API and render the template with the returned results. I'd like to avoid requiring editing the .htaccess file like some caching plugins do. Some of the admins of these pages won't know how to do that or simply won't have access to the .htaccess file. Thanks!

  • SQL Stored Procedure

    - by Nathan
    I am trying to run a stored procedure with a while loop in it using Aqua Data Studio 6.5 and as soon as the SP starts Aqua Data starts consuming an increasing amount of my CPU's memory which makes absolutely no sense to me because everything should be off on the Sybase server I am working with. I have commented out and tested every piece of the SP and narrowed the issue down to the while loop. Can anyone explain to me what is going on? create procedure sp_check_stuff as begin declare @counter numeric (9), @max_id numeric (9), @exists numeric (1), @rows numeric (1) select @max_id = max(id) from my_table set @counter = 0 set @exists = 0 set @rows = 0 while @count <= @max_id begin //More logic which doesn't affect memory usage based //on commenting it out and running the SP set @counter = @counter + 1 set @exists = 0 set @rows = 0 end end return

    - by mp0int
    I ned to write a code sniplet that enables to disable connection to some parts of a site. Admin and the mainpage will be displayable, but user section (which uses ajax) will be displayed, but can not be used (vith a transparent div set over the page). Also there is a few pages which will be disabled. my logic is that, i write a middleware, def process_request(self, request): if ayar.tonline_kapali: url_parcalari = request.path.split('/') if url_parcalari[0] not in settings.BAGIMSIZ_URLLER: if not request.is_ajax(): return render_to_response('bakim_modu.html') else: return None that code let me to display a "site closed" message for the urls not in BAGIMSIZ_URLLER (which contains urls that will be accessible) But i do not figure out how can i solve the problem about ajax pages... i need to set a header or something to the response and need to check it in the template.

  • How to? - part of the site over ssl, other part not

    - by spirytus
    What is common practice for coding web applications where part of the site has to be secured (e.g. checkout section) and part not necessarily, lets say homepage. As far as I know sharing sessions in between http and https parts of the site is not easily possible (or is it?). What would be common approach if I wanted to display on http page like homepage, shopping cart data (items) that users ordered on https pages? How those two parts of the site would communicate if necessary? Also isn't it security flaw in popular shopping carts as it seems that many of these have only checkout pages secured (ssl) and the rest not? I'm using php if it makes any difference.

  • opening iWorks documents in iPad UIWebView

    - by user369156
    Hello, I'm writing an iPad application that has a UIWebView which I open word and excel documents in, but I want the user to be able to import those documents into the iWorks applications, Pages and Numbers, just like how you can do it in Safari if you open a document. If you open a document in Safari on the iPad, there'll be a button on the top bar that says "Open in..." and you can choose applications to open in. You get the top bar to appear by tapping on middle of the page. So is there an option you can set to allow UIWebView to show up the bar and automatically detect the content type and populate the list with applications you can import in? Or do I have to build this myself? And if I have to build my own, how do I open URLs to import documents into Pages and Numbers etc? Thanks, -David

  • How to prevent virtual machines's copy

    - by Florent
    I'll have to deploy virtual machines on demo laptops, which will use Vmware player, but I've got some security concerns, as some data stored in the virtual machines are a bit sensitive. Is there a way to prevent the copy of these virtual machines ? Are the virtual hard drives encrypted, and if not is there a way to encrypt them ? In short, is there a way to lock down everything so that nobody could copy and or use these VMs in another computer ?

  • Automated browsing with javascript?

    - by Paul Wicks
    I'm trying to do some browser automation, but I'm having some problems. Basically, what I'd like to do is load a set pages, set some forms options, click a button and view the results for each page that I open. Originally, I tried to do this by placing the pages I wanted to automate in iframes and then using javascript to drive the interactions I want in each, but that results in a Permissions Error, since the sites I want to automate are not on my server. Is there any way around this? The other possibility I've thought of is to use QT's webkit class and the evaluateJavaScript method to accomplish what I'd like to do, but this seems a bit more heavy weight for something that is, conceptually, pretty simple.

  • onbeforeunload dilemma: iframe breaking vs. annoying message on refresh/back buttons click

    - by Tossapol
    I'm implementing a search service called SearchInsideOut. http://bit.ly/97SFyW This search service simply replaces web page results by full web pages (Yes, I used iframe). The problem I have to deal with is iframe-breaking pages. The promising solution I found is using onbeforeunload to let users decide whether to stay or leave my site. But this also creates another annoying behavior. When users click other links in my site, onbeforeunload will also be triggered. Fortunately, I could solve this case by placing window.onbeforeunload=null in the onclick event of those links of my site. Unfortunately, I have no idea how to detect external events like clicking "refresh/back" buttons. What should I do to solve this difficulty? All suggestions and comments are highly appreciated.
