• How do I make a new Moose class and instantiate an object of that class at runtime?

  - by xxxxxxx

  After creating a metaclass using Moose::Meta::Class->create, how do I instantiate a real Moose class with that class as a metaclass? (I need to create the metaclass also because I also want to apply some roles to it.)

• Rotate webpage via code?

  - by Adam Davis

  I'm hoping that there's a relatively simple way to rotate a webpage a little bit, 30 degrees or so, while still leaving it fully functional and usable. I completely control the page, and can modify it to make this easier if needed. I'd rather not re-write the whole thing in SVG, though, but perhaps javascript and canvas will work? Is there a way using CSS, Javascript, or some other cross browser method that would allow me to accomplish this?

• Minimalistic tools for developer documentation

  - by Pekka

  I am currently working on a large PHP CMS / Framework and documenting it extensively as I go along. In addition to phpdoc-style inline comments, I need to document XML structures, details on concepts and practices, write HOWTOs and so on. At the moment, I am using simple OpenOffice documents for that, but I'm unhappy with it and looking for a "real" documentation system. So, I am looking for recommendations for robust, minimalistic, easy-to-use documentation software. I have tried a number of Wikis, most prominently Dokuwiki. I like the open-minded approach, the freedom in editing, and the simplicity, but they provide little support in structuring a multi-chapter documentation, and make basic reorganisation tasks very difficult (e.g. moving pages to a different namespace). Working with the plugins is Cumbersome, and they are not really easy to use. Open Source would be a plus but is not a requirement. Thanks for all the suggestions. I have not had time to look into each one in detail. I will be trying Sphinx, especially because it provides so much support for a good structure. I may update this post later when I'm done and report how it worked out. The suggestions Trac's built-in wiki which is great but for my taste provides too little support for keeping a structure - it's perfect though for "normal", smaller size project documentation Markdown my current favourite because of its minimalism, however not sure yet whether maintaining a structure will be easy enough. A Markdown-Based system would of course be very easy to extend, e.g. to look up cross references from the project's code base. Of course it would be great to find something that already has that out of the box. The DocBook format and to edit, the commercial Oxygen XML Editor - a great standard for building documentation, no doubt. Maybe too "technical" for my purposes as I need something to open quickly, write into and go on coding. Still always worth a mention. Sphinx an Open Source, Python based documentation generator, promising structured documentation and extensive cross-referencing. Interesting and will take a look. Confluence a commercial but very affordable Wiki. XWiki, an Open Source playing in Confluence's league with numerous extensions and connectors to Eclipse and Microsoft Office. TiddlyWiki an open-source Wiki.

• How to merge a "branch" that isn't really a branch (wasn't created by an svn copy)

  - by MatrixFrog

  I'm working on a team with lots of people who are pretty unfamiliar with the concepts of version control systems, and are just kind of doing whatever seems to work, by trial and error. Someone created a "branch" from the trunk that is not ancestrally related to the trunk. My guess is it went something like this: They created a folder in branches. They checked out all the code from the trunk to somewhere on their desktop. They added all that code to the newly created folder as though it was a bunch of brand new files. So the repository isn't aware that all that code is actually just a copy of the trunk. When I look at the history of that branch in TortoiseSVN, and uncheck the "Stop on copy/rename" box, there is no revision that has the trunk (or any other path) under the "Copy from path" column. Then they made lots of changes on their "branch". Meanwhile, others were making lots of changes on the trunk. We tried to do a merge and of course it doesn't work. Because, the trunk and the fake branch are not ancestrally related. I can see only two ways to resolve this: Go through the logs on the "branch", look at every change that was made, and manually apply each change to the trunk. Go through the logs on the trunk, look at every change that was made between revision 540 (when the "branch" was created) and HEAD, and manually apply each change to the "branch". This involves 7 revisions one way or 11 revisions the other way, so neither one is really that terrible. But is there any way to cause the repository to "realize" that the branch really IS ancestrally related even though it was created incorrectly, so that we can take advantage of the built-in merging functionality in Eclipse/TortoiseSVN? (You may be wondering: Why did your company hire these people and allow them to access the SVN repository without making sure they knew how to use it properly first?! We didn't -- this is a school assignment, which is a collaboration between two different classes -- the ones in the lower class were given a very quick hand-wavey "overview" of SVN which didn't really teach them anything. I've asked everyone in the group to please PLEASE read the svn book, and I'll make sure we (the slightly more experienced half of the team) keep a close eye on the repository to ensure this doesn't happen again.)

• Retrieve jquery-ui dialog's div

  - by Hikari

  When we apply $().dialog() in an object, jquery-ui puts it inside a <div class="ui-dialog ui-widget">, with a <div class="ui-dialog-titlebar ui-widget-header"> before it. After the creation of this dialog around the main object, how can we get that ui-dialog object so that we can execute other JavaScript commands in it? The best I could do was use .parent(".ui-dialog") in the main object, is there a better way to do it?

• Speed up login to StarTeam?

  - by Slapout

  I'm working on a program that accesses StarTeam using the StarTeam SDK for .NET. And I've noticed that it takes about 10 seconds to login to the StarTeam server. I'm wondering if there's anything I can do to speed that up. Edit I used this command to run the StarTeam Cross Platform client with debugging output: stjava.exe StarTeamCP.stjava -- -netmon It appears that the delay happens when it send the command SRVR_CMD_GET_USER_PERSONAL_INFO. So I don't think there's anything I can do to speed it up.

• WPF Applying a trigger on binding failure

  - by Aran Mulholland

  This question is a follow on from this one... I am binding to a heterogeneous collection of objects, not all objects have the same set of properties. I am doing this in a datagrid. I would like to gray out the cell if the binding fails. Is there a way to apply a trigger if a binding fails?

• MVC 2 AntiForgeryToken - Why symmetric encryption + IPrinciple?

  - by Brad R

  We recently updated our solution to MVC 2, and this has updated the way that the AntiForgeryToken works. Unfortunately this does not fit with our AJAX framework any more. The problem is that MVC 2 now uses symmetric encryption to encode some properties about the user, including the user's Name property (from IPrincipal). We are able to securely register a new user using AJAX, after which subsequent AJAX calls will be invalid as the anti forgery token will change when the user has been granted a new principal. There are also other cases when this may happen, such as a user updating their name etc. My main question is why does MVC 2 even bother using symmetric encryption? Any then why does it care about the user name property on the principal? If my understanding is correct then any random shared secret will do. The basic principle is that the user will be sent a cookie with some specific data (HttpOnly!). This cookie is then required to match a form variable sent back with each request that may have side effects (POST's usually). Since this is only meant to protect from cross site attacks it is easy to craft up a response that would easily pass the test, but only if you had full access to the cookie. Since a cross site attacker is not going to have access to your user cookies you are protected. By using symmetric encryption, what is the advantage in checking the contents of the cookie? That is, if I already have sent an HttpOnly cookie the attacker cannot override it (unless a browser has a major security issue), so why do I then need to check it again? After having a think about it it appears to be one of those 'added layer of security' cases - but if your first line of defence has fallen (HttpOnly) then the attacker is going to get past the second layer anyway as they have full access to the users cookie collection, and could just impersonate them directly, instead of using an indirect XSS/CSRF attack. Of course I could be missing a major issue, but I haven't found it yet. If there are some obvious or subtle issues at play here then I would like to be aware of them.

• What's the most accurate way to determine user geolocation in the browser?

  - by Crashalot

  I found a few examples suggesting Google AJAX APIs. This link typifies the advice I have found so far: http://briancray.com/2009/05/29/find-web-visitors-location-javascript-google-api/ However, the location is often wrong with the Google APIs. Other sites seem to know exactly which city I'm in, though, without me entering any information. Suggestions? Is there something cross-browser (ignoring IE6) and reliable?

• Stand-alone Java code formatter/beautifier/pretty printer?

  - by Greg Mattes

  I'm interested in learning about the available choices of high-quality, stand-alone source code formatters for Java. The formatter must be stand-alone, that is, it must support a "batch" mode that is decoupled from any particular development environment. Ideally it should be independent of any particular operating system as well. So, a built-in formatter for the IDE du jour is of little interest here (unless that IDE supports batch mode formatter invocation, perhaps from the command line). A formatter written in closed-source C/C++ that only runs on, say, Windows is not ideal, but is somewhat interesting. To be clear, a "formatter" (or "beautifier") is not the same as a "style checker." A formatter accepts source code as input, applies styling rules, and produces styled source code that is semantically equivalent to the original source code. A style checker also applies styling rules, but it simply reports rule violations without producing modified source code as output. So the picture looks like this: Formatter (produces modified source code that conforms to styling rules) Read Source Code → Apply Styling Rules → Write Styled Source Code Style Checker (does not produce modified source code) Read Source Code → Apply Styling Rules → Write Rule Violations Further Clarifications Solutions must be highly configurable. I want to be able to specify my own style, not simply select from a canned list. Also, I'm not looking for a general purpose pretty-printer written in Java that can pretty-print many things. I want to style Java code. I'm also not necessarily interested in a grand-unified formatter for many languages. I suppose it might be nice for a solution to have support for languages other than Java, but that is not a requirement. Furthermore, tools that only perform code highlighting are right out. I'm also not interested in a web service. I want a tool that I can run locally. Finally, solutions need not be restricted to open source, public domain, shareware, free software, commercial, or anything else. All forms of licensing are acceptable.

• jQuery slide effect

  - by Ayrton

  Hi I'm looking for a slide effect for a navigation. But in my opinion the slide effect of jQuery is a little strange, or doesn't really fit my needs. The list items kind of appear but aren't animated (the container is only animated) when I apply the slideDown,slideUp,toggleSlide effect. I would like to have the list items animated as well. I've found an example of this: http://www.creative-exposure.co.uk/ If you someone could help me out, I would really appreciate it. yours truthfully

• Scrolling a listbox with page up/down

  - by orca

  I had an ItemsControl, which you could use page up/down buttons to scroll expectedly. I switched it with a ListBox, to apply (thru triggers) a new DataTemplate when an item is selected. Everything works fine, until using pageup or pagedown buttons. Instead of scrolling one page, it scrolls till the end or the beginning. My previous attemps: Not changing the item height when DataTemplate changes Removed IsSelected=True trigger completely All SelectionMode values Do I miss something trivial?

• Built-in precedence in Expression Trees for math?

  - by jdk

  I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.
