• Does any language use "=/=" for denoting the not-equal operator

  Does any programming language use =/= for not-equal? Are there any lexical difficulties for scanners to recognize such an operator? Or was it the case historically? [Note: this is NOT a homework question. I'm just curious.]

• Local development using HTML5 storage

  - by jasongonzales

  I am experimenting with HTML5 local storage functionality, but was frustrated to learn that the browser won't allow local storage when the file is local. My guess is that the browser (Chrome in my case, FF too) wants to see a domain rather than a file location. Has anyone here discovered a workaround for developing locally? Perhaps setting up a local domain? That sounds like too much trouble. There should just be a developer option in the browser, grrrrrr.

• .NET: How to place my window near the notification area (systray)?

  - by Vilx-

  I'd like to display a little popup window next to the notification area. It's similar to what Outlook/Skype/Live! Messenger/etc does when it displays the notification about a new message. In my case it will have some input controls (textbox, datetimepicker, buttons...) so a simple bubble won't do. The trick is doing this correctly when the user has multiple monitors and/or the taskbar is not located at the bottom of the screen.

• How do you get the width of an element without a defined width?

  - by Moak

  How would you find out the width of a element that is wrapped by 20 odd other elements, but the only fixed width I know is the main wrapper's which is 800px. All child elements are generally blocks, floating or not, with different paddings and margins. I don't really need the answer to a specific case, I'm just wondering if there are tools or tricks to quickly calculate such things. Thanks

  XNA games have an Unload() method, where content is supposed to be unloaded. But what is the point of this? If all the content is being unloaded, then the game must be exiting, in which case everything would be garbage collected anyway, right?

• Why Java does not allow overriding equals(Object) in an Enum?

  - by Ashwin Prabhu

  @Override public boolean equals( Object otherObject ) is not allowed in Java for an Enum, since the method equals(Object x) is defined as final in Enum. Why is this so? I cannot thing of any use case which would require overriding equals(Object) for Enum. I'm just curious to know the reasoning behind this behavior.

• Is it possible in Android Market to delete an existing FREE app and reupload it again as a PAY app?

  - by watcherFR

  I have an app I am offering for free for now. At some point, I want to be able to change it to a pay app. The market doesn't allow a free app to become for-pay and doesn't allow for-pay apps to be priced at 0$. So is it possible to just delete the original app and then reupload it as a for-pay app ? It's okay in my case if users aren't notified of updates.

• Why thread specific data is required in pthread ?

  - by user504542

Since each thread has its own stack, the local variables that are created inside the thread is unique. In this case, why do we need to go for thread specific data mechanism?. Can't it be achieved by auto storage varibles inside the thread function ? Kindly clarify!!!. BR Rj
