  • Qt QTableView and horizontalHeader()->restoreState()

    - by cheez
    I can't narrow down this bug, however I seem to have the following problem: - saveState() of a horizontalHeader() - restart app - Modify model so that it has one less column - restoreState() - Now, for some reason, the state of the headerview is totally messed up. I cannot show or hide any new columns, nor can I ever get a reasonable state back I know, this is not very descriptive but I'm hoping others have had this problem before.

  • How to REALLY focus a link using jQuery / javascript

    - by Bobby Jack
    Calling the jQuery focus() method on a link appears to only partially focus the link. Whilst the link has focus to the extent that pressing ENTER follows the link, it doesn't take on the default outline styling (or adopt any styling set via the :focus pseudo-class), nor is the tab-order correctly 'entered'. Any ideas on how to resolve this? (results observed in Firefox 3.6.2)

  • Open-sourcing a mobile app

    - by hgpc
    I'm considering making one of my most popular mobile apps into an open-source project. It has an Android and iPhone version. While I have used open-source projects and submitted feature requests and bug reports, I have never created an open-source project nor contributed with a patch to an existing one. What are the top things that I should take into account before opening the source of my project? What specific steps do you recommend taking for open-sourcing a mobile app?

    - by Ronald
    Anybody out there notice anything wrong with this JSON? It validates at JSONLint.com, but neither Chrome nor Firefox's native JSON parse functions will properly parse it. Any ideas? { "result": "{\"players\":[{\"name\":\"User 522\",\"turn\":true,\"score\":0},{\"name\":\"User 925\",\"turn\":false,\"score\":5}],\"enableControls\":false}", "error": "null", "id": "7" }

  • Ruby - How to remove a setter on an object

    - by Markus Orrelly
    Given a class like this: class B class << self attr_accessor :var end end Suppose I can't modify the original source code of class B. How might I go about removing the setter on the class variable var? I've tried using something like B.send("unset_method", "var="), but that doesn't work (nor does remove_method, or overwriting that method with a var= method that doesn't do anything). Any ideas?

  • Array.sort Sorting Stability in Different Browsers

    - by Boushley
    What is the stability of Array.sort in different browsers. I know that the ECMA Script specification does not specify which algorithm to use, nor does it specify whether the sort should be stable. I've found this information on for Firefox https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/Array/sort which specifies that firefox uses a stable sort. Does anyone know about IE 6/7/8, Chrome, Safari?

  • asp.net web app - writing data to access or error logs?

    - by chris
    I'm looking for a quick way to log some data - I seem to remember a way to write to the access log, similar to System.Out.Println() but I can't seem to remember how to do it. I can't attach a debugger, nor can I add additional information to the web app via Response.Write(). Is there a simple way - a single statement with no configuration changes would be ideal - to write to either the error or access logs?

  • Does anyone use AMPL anymore

    - by steven
    I took a class on "Intelligent Decision Making" (which was mostly an Problem Optimization class). In the class we learned about AMPL and how to extend the solvers. I haven't heard much about it lately, nor have I seen job listings for it. My question is: Is AMPL still in use anymore? If so what is it being used for? Yes, I do understand that AMPL can be replaced with Matlab, however AMPL is free and Matlab isn't even close.

  • Slick: why would I save "Unit" to my database?

    - by alapeno
    I'm new to Scala and Slick and was surprised by something in the Slick documentation: The following primitive types are supported out of the box for JDBC-based databases in JdbcProfile ... Unit ... I don't get why this list contains Unit. From my understanding, Unit is similar to Java's void, something I neither can save to nor receive from my database. What is the intention behind it? edit: you can find it here.

  • Web application starter kit

    - by Steve Robillard
    I am looking for a site that allows you to input a project name, choose a doctype, a js library etc. and then generates the directory structure and files to start a web project. I know about project deploy, but it is no longer maintained. There was a new one that was created within the last 2 or 3 months, but for the life of me I can't find it either through Google nor my delicious bookmarks. Any help would be greatly appreciated. Thanks, Steve
