  • In Bash, how do you access command line arguments inside a function?

    - by DonGar
    I'm attempting to write a function in bash that will access the scripts command line arguments, but they are replaced with the positional arguments to the function. Is there any way for the function to access the command line arguments if they aren't passed in explicitly? # Demo function function stuff { echo $0 $* } # Echo's the name of the script, but no command line arguments stuff # Echo's everything I want, but trying to avoid stuff $*

  • How to set cookies via PHP in the middle of a document?

    - by Sam
    Hi all, how can I set cookies in the middle of a document, without incurring a 'headers already sent' error? What I'm trying to do is make a log out script (the log in cookie setting works...so odd. Is it because it's enclosed in an if statement?) however I've already echoed the page title and some other stuff at the top of the page, before I've made this logout happen. Thanks!

  • json data not rendered in backbone view

    - by user2535706
    I have been trying to render the json data to the view by calling the rest api and the code is as follows: var Profile = Backbone.Model.extend({ dataType:'jsonp', defaults: { intuitId: null, email: null, type: null }, }); var ProfileList = Backbone.Collection.extend({ model: Profile, url: '/v1/entities/6414256167329108895' }); var ProfileView = Backbone.View.extend({ el: "#profiles", template: _.template($('#profileTemplate').html()), render: function() { _.each(this.model.models, function(profile) { var profileTemplate = this.template(this.model.toJSON()); $(this.el).append(tprofileTemplate); }, this); return this; } }); var profiles = new ProfileList(); var profilesView = new ProfileView({model: profiles}); profiles.fetch(); profilesView.render(); and the html file is as follows: <!DOCTYPE html> <html> <head> <title>SPA Example</title> <!-- <link rel="stylesheet" type="text/css" href="src/css/reset.css" /> <link rel="stylesheet" type="text/css" href="src/css/harmony_compiled.css" /> --> </head> <body class="harmony"> <header> <div class="title">SPA Example</div> </header> <div id="profiles"></div> <script id="profileTemplate" type="text/template"> <div class="profile"> <div class="info"> <div class="intuitId"> <%= intuitId %> </div> <div class="email"> <%= email %> </div> <div class="type"> <%= type %> </div> </div> </div> </script> </body> </html> This gives me an error and the render function isn't invoking properly and the render function is called even before the REST API returns the JSON response. Could anyone please help me to figure out where I went wrong. Any help is highly appreciated Thank you

  • Is there a way that I can force mod_perl to re-use buffer memory?

    - by Pavel Georgiev
    Hi, I have a Perl script running in mod_perl that needs to write a large amount of data to the client, possibly over a long period. The behavior that I observe is that once I print and flush something, the buffer memory is not reclaimed even though I rflush (I know this can't be reclaimed back by the OS). Is that how mod_perl operates and is there a way that I can force it to periodically free the buffer memory, so that I can use that for new buffers instead of taking more from the OS?

  • How to measure Silverlight control load time with Google Analytics

    - by ddehghan
    Hi everyone I have a simple silverlight page for for finding available domain names. I use Google Analytics for monitoring the traffic. I would really like to find out how long it take for users to download and render the Silverlight control. Once the java script on a page is loaded there should be a way to start a timer and then stop the timer once the Silverlight control is loaded. Key points I would like to measure are: Time it takes to download the silverlight control Time it takes to initialize the control Thanks

  • Get computed font size for DOM element in JS

    - by Pekka
    Is it possible to detect the computed font-size of a DOM element, taking into consideration generic settings made elsewhere (In the body tag for example), inherited values, and so on? A framework-independent approach would be nice, as I'm working on a script that should work standalone, but that is not a requirement of course. Background: I'm trying to tweak CKEditor's font selector plugin (source here) so that it always shows the font size of the current cursor position (as opposed to only when within a span that has an explicit font-size set, which is the current behaviour).

  • Database Schema Versioning Strategies

    - by Jack Ryan
    I work on a project that uses a reasonably large database, the live version weighing in at somewhere around 60-80GB. The live database is the only real definitive source of our schema, and because of its size duplicating this database is too slow to be done often. This means we have ended up developing our database schema in a pretty ad hoc way, using sql compare to migrate changes from dev dbs to the live system, and only wiping our dev dbs every month or two. I am hoping to get some pointers on how to improve our database development work flow so that we have a little more control. Some things to think about: Currently nobody is really in charge of the database schema, all developers can change it if they need to, though generally these decisions are talked about before they are done. There are stored procedures, functions, and views in the database. These should probably be dumped to files so they can be reloaded on every build. Schema changes should probably be checked in as scripts. We have started to do this recently. However all our scripts must then be numbered (because there may be dependencies between them), and must be re runnable (because our build script currently runs them all in order). This makes them hard to read because they are full of conditionals that check whether tables or columns already exist. This is a step that is often forgotten by developers. Getting a new database should be quick and easy. This is currently a big problem, it takes several hours to get a copy of last nights backup and restore it onto a dev machine. Some mechanism needs to be in place to allow developers to update static data. We have tables that contain data that is never updated through the application, but does potentially need to be changed when we do a new release (often this drives dropdowns). The whole thing needs to be runnable as part of a build script. Are there any tools that can be used to help to do this? Eventually I would like to be at a point where a new DB can be built from scratch without copying any data from the live system. I don't mind writing some scripts to glue all the steps together but each part should be easily editable so that we continue to use it rather than make changes directly on DBs.

  • How can I test a windows dll to determine if it is 32bit or 64bit?

    - by morechilli
    I'd like to write a test script or program that asserts that all dlls in a given directory are of a particular build type. I would use this as a sanity check at the end of a build process on an sdk to make sure that the 64bit version hasn't somehow got some 32bit dlls in it and vice versa. Is there an easy way to look at a dll file and determine its type? The solution should work on both xp32 and xp64.

  • ASP.NET Master Page + pageLoad() = kills jquery?

    - by Clay Angelly
    In my MasterPage, I have a ScriptManager that has a ScriptReference to my jquery.js file. This has always worked with no problems, all content pages that utilize jquery work fine. Recently, I added the following javascript script block at the end of my MasterPage: function pageLoad(sender, args) { } By simply adding the above pageLoad method, no jquery code is executed from any of my content pages. Why would just having a pageLoad in the Master Page have this effect? Thanks in advance for any insight.
