function touchHandler(event)
{
var touches = event.changedTouches,
first = touches[0],
type = "";
switch (event.type)
{
case "touchstart": type = "mousedown"; break;
case "touchmove": type = "mousemove"; break;
case "touchend": type = "mouseup"; break;
default: return;
}
//initMouseEvent(type, canBubble, cancelable, view, clickCount,
// screenX, screenY, clientX, clientY, ctrlKey,
// altKey, shiftKey, metaKey, button, relatedTarget);
var simulatedEvent = document.createEvent("MouseEvent");
simulatedEvent.initMouseEvent(type, true, true, window, 1,
first.screenX, first.screenY,
first.clientX, first.clientY, false,
false, false, false, 0/*left*/, null);
first.target.dispatchEvent(simulatedEvent);
event.preventDefault();
}
It appears to work fine if I attach the touchHandler to the `document` touchstart/move/end, but then no native zooming/scrolling on the iPad is allowed, so I am trying to just attach this handler to the draggables themselves.
The issue that I am seeing with this is that `event.changeTouches` is always undefined for some reason, as you can witness in http://jsfiddle.net/myLj2/1/ . I can't come up with a reason why a touch event will always have an undefined `changeTouches` property and because of it, this code won't work. Any thoughts? | javascript | jquery | jquery-ui | touch-events | null | null | open | Handling iPad touch events for draggables/droppables (undefined changedTouches)

-which is better programming language A or B?
-what programming language should i learn ?
i came to the conclusion that those questions are "wrong" questions because the choice of programming language is governed by many factors including but not limited to the type of job on hand / your programming experience / targeted platforms ....etc.so the choice of programming language should be tailored to the job.
therefore , the correct question would be :
of all the programming languages you know , tell us :
1-advantages
2-disadvantages
3-the type /domain of applications in which that language is best suited to and why it is.
4- any other comments
if you know more than one language it is also very useful to give some comparison.
by sharing your experience with novice programmers who want to jump into the programming world you will help them to make informed decisions.

When developing an application that uses media files(images, videos, xml files etc) that are constantly changed and almost every application version (or revision) is using a unique set of these media files which are not compatible with previous (or future) versions of these files. When this application uses certain versions of third party libraries which are incompatible with their previous or future versions. Is it a common practice to store all these binary files in the repository, e.g. SVN?
I think yes.
Pros:
- If the project is big and some functionality was broken in it or a bug have appeared you can always do an "Update to revision" and find that place where the bug appeared. And fix it.
- Making checkout and building the application is easy, because you have everything you need in your working copy to build the application
Cons:
- SVN server will need much HDD space to store all the versions. Somebody says that it becomes sluggish
- SVN Updates are slow
Are there any other advantages of storing only source code files in the repository? | svn | version-control | null | null | null | null | open | Should library and media files be stored in the repository?

Need less to say, the properties/bindings are not know as they can vary across elements/controls we are loading.
As the run time view model context is not available when we load the control for preview - after loading the Element, the idea is to grab the binding information, create a type with those propertes at run time, to assign the same as the data context of the loaded control.
We'll be using AssemblyBuilder/ModuleBuilder/TypeBuilder to build a type at run time. Having said that, we need to walk the visual tree to identify the bindings involved, to create a list of binding paths.
Obviously, one way is to use regex to parse the xaml directly and build this list.. Just want to know a way exist so that I can grab the bindings and related paths from the visual tree itself?

I quickly found two alternatives, namely the `hashchange` event and the HTML5 History API. Both options are available through jQuery plugins, which of course makes them easier to use. I'm leaning towards [History.js][1] as the HTML5 solution seems to be the way to go and this plugin gracefully degrades for "older" (IE9 is not that old) browsers.
However, from the documentation I'm not sure whether the plugin is suitable for my needs. I have a site which is build using ASP.NET MVC and various pages are rendered based on the results from AJAX POSTs.
Now I'm wondering how to modify the state of a page after the HTML is returned from the Action and rendered on the page. The resulting HTML is based on the information in the POST header (usually some kind of JSON object). Should I store the JSON in the page state? And how can I bookmark this as the information cannot be stored in the URL due to size limitations.
--------------------------------
Having written the above, I realise it might be difficult to answer this question without some context. Basically we use (abuse?) the POST to retrieve (parts of) new pages. We could not do this using a standard GET as the size of the URL became too big due to the number and size of the parameters. However, now we run into the common problem when AJAXifying a webpage, namely that you cannot bookmark the resulting pages unless some action is undertaken. This lead us to the jQuery plugins mentioned above. However, it is not clear how an API like History.js can be used to allow creation of bookmarks for pages which are (partly) the result of AJAX POST requests. How is the state retained if someone deeplinks to a page which contained such results when the bookmark was created?
--------------------------------
Anyway, I hope this provides some more context on the origin of the question. Thanks for anyone who can shed some light on this

I have a test method that is run. When the method generates an exception I want to know what the name of the test was and the exception content.
In the teardown for the test I want to get access to this information. How would I get access to it from the TearDown attributed method? | 0 |

I have a program which simulates directory "copy-on-write" functionality, by hardlinking all entries. Currently all the underlying code, some of which I don't have access to, uses standard `open(fname, 'w')` to write the regular files.
But with hardlinks, this means the same inode is used (just truncated), so the original content is destroyed as well. For copy-on-write, I would of course want the original to remain untouched (old inode) and the `open('w')` call to create a new inode.
Any ideas on the best way to achieve this? Monkey-patch `open` somehow?
What I came up with so far is overriding `open` to try to delete the file first (if it exists) and only then do `open('w')`.

I would really appreciate your opinion.
Maybe I should just say F all this, and create my static pages with straight HTML/CSS, and then use a blogging platform like Tumblr or WordPress strictly for blog posts, as per Sproutcore?

It works currently on a couple of old XP PCs and I was asked to see if I could get it working on Windows 7 64bit. Well… that was a no go, so I tried a 32bit version to verify that 64 wasn’t the issue and it didn’t work. So I then created an XP virtual machine and it didn’t work either. The issue is the same on all three environments. You double click the .exe and nothing is displayed but when you look under task manager, it’s there and pegging the CPU.
I downloaded Dependency Walker and it seems that all the required dlls and OCX files are there. Can anyone suggest anything else? I’m really at a loss here. Anything would be appreciated!

I have one virtual machine for my web server, another for my zimbra server, another for my mysql server, and another that runs windows xp for testing.
My problem is where to store the data. Web files, email files, mysql, etc?
Which of these scenarios are the best?
* Each virtual machine stores it's own data on it's own virtual hard disk
* Create a new virtual machine for data storage and use Samba or NFS to share
* Use Samba or NFS on the host machine to share the data
* something else i haven't thought of yet
I know that storing Mysql data files remotely via NFS or Samba is a bad thing but I would like to keep my data consolidated together. (Or maybe i'm on crack for thinking that)
Anyway, please set me straight! Thanks. | vmware-server | null | null | null | null | 03/24/2009 22:19:51 | off topic | Where should I store data on a VMWare Server (or any virtual machine) install?
===
I have a Linux server at home that runs VMWare Server. I have one virtual machine for my web server, another for my zimbra server, another for my mysql server, and another that runs windows xp for testing.
My problem is where to store the data. Web files, email files, mysql, etc?
Which of these scenarios are the best?
* Each virtual machine stores it's own data on it's own virtual hard disk
* Create a new virtual machine for data storage and use Samba or NFS to share
* Use Samba or NFS on the host machine to share the data
* something else i haven't thought of yet
