    I'd like to send data to browser from server (website). For example on SO you receive notifications about new answers when answering a question. Should I every n seconds send ajax queries to server, or there are better ways of doing this? Is it possible to push data from server to browser?

I figure that i can make my own class that implements InputStream and just consolidates two input streams (the file first, my additional data to append second.) but is there an existing view class that i can use to just return an InputStream or will i have to roll my own view class as well?

  • What are real world examples of when Linked Lists should be used?

    - by oo
    Another programmer was mentioning that they haven't found a use case for using a linked list data structure in any professional software in his career. I couldn't think of any good examples off the top of my head. He is mostly a C# and Java developer Can anyone give some examples where this was the correct data structure to solve a particular real world problem? Related: What is a practical, real world example of the Linked List?

  • Offline database access

    - by dtech
    I have a small application which basically consists of an user-friendly CRUD interface to a few tables (and joined tables) It currently works with a MySQL database but I would like to make it available offline. My first thought was to create a SQLite "buffer" in between the MySQL database and the application, e.g. by executing all queries on the SQLite but also storing them in a log table so that they can be executed later in the main database with very basic conflict resolution (I will basically let the user solve it if a conflict is detected) Due to the simplicity of the application this shouldn't be too difficult and good exercise, but I think I would be re-inventing the wheel. So my question is: are there existing solutions or other approaches for this problem?

  • Is there any way to access codeigniter language and config properties from included javascript files

    - by ubermensch
    Good morning! I'm having great success so far with CodeIgniter. I'm new to PHP and web development in general, but I feel that CodeIgniter is giving me a leg up while I catch up on the basics. My question for today is this - I have been happily loading config and lang values from my views for a while now, and everything is working fine. But what about JavaScript files being linked into my views? Is there any way to make the $this-lang-line and $this-config-item function references available to me in my JavaScript files? I am implementing jQuery client-side validation, and would like to pull in my error messages from the server, both to support internationalisation and to make sure that validation gracefully degrades if JavaScript is not available, in that the error messages pushed back into the view from the server-side validation are identical to those displayed dynamically by the jQuery validation. I would not like to have to keep coming back to make sure that these strings are kept in sync. As for internationalisation, I'm fresh out of ideas on how to support that if it turns out that lang and config item strings are completely unavailable from my JS files. Any help you can provide would be greatly appreciated! :)

  • Clojure: I have many sorted maps and want to reduce in order all there values a super maps of keys -> vector

    - by Alex Foreman
    I have seen this but can't work out how to apply it (no pun intended) to my situation. I have a sorted list of maps like this: (note there can be more than two keys in the map) ({name1 3, name2 7}, {name1 35, name2 7}, {name1 0, name2 3}) What I am after is this data structure afterwards: ({:name1 [3,35,0]}, {:name2 [7,7,3]}) Ive been struggling with this for a while and cant seem to get anywhere near. Caveats: The data must stay sorted and I have N keywords not just two.

  • Can't access media assets in an SWC

    - by Sold Out Activist
    I'm having trouble accessing content in an SWC. The main project compiles without error, but the assets (sound, music) aren't displayed or played. My workflow: i. Using Flash CS5 1. Create MAsset.fla 2. Import sounds, art 3. Assign class names, check export in frame 1 4a. Write out the classes in the actions panel in frame 1 4b. OR. Add a document class and write out the classes there 5. Export SWC. Filesize is similar to what it is when I directly import assets in the main project library. 6. Create Project.fla and document class Project.as 7. Import SWC into main project through the Actionscript panel. 8. Add code, which calls the class names from the SWC (e.g. DCL_UI_MOUSE) 9. Compile. No compiler errors, but nothing doing. And the resulting SWF filesize doesn't reflect anything more than the compiled code from the main project. Regarding step 4, if I just write the class name in the root timeline or document class, the compiler error will go away and the asset appear to be compiled in the SWC. But I have also tried: var asset0000:DCL_UI_MOUSE; And: var asset0000:DCL_UI_MOUSE = new DCL_UI_MOUSE(); Regardless the assets don't make it into the final SWF. What am I doing wrong?

  • How to generate sample XML documents from their DTD or XSD?

    - by lindelof
    We are developing an application that involves a substantial amount of XML transformations. We do not have any proper input test data per se, only DTD or XSD files. We'd like to generate our test data ourselves from these files. Is there an easy/free way to do that? Edit There are apparently no free tools for this, and I agree that OxygenXML is one of the best tools for this.
