• Is the Keychain suitable for storing general data, such as strings?

  - by cannyboy

  The Keychain seems to be used a lot for usernames and passwords, but is it a good idea to use it for other sensitive stuff (bank details, ID numbers etc), but with no password? What kind of encryption does the keychain use? The scenario I'm concerned about is a thief acquiring an iPhone (which is screen-locked) and being able to access the file system to get this info. Also, would using the Keychain involve export restrictions due to the use of encryption?

• Does Java support default parameter values?

  - by gnavi

  I came across some Java code that had the following structure: public MyParameterizedFunction(String param1, int param2) { this(param1, param2, false); } public MyParameterizedFunction(String param1, int param2, boolean param3) { //use all three parameters here } I know that in C++ I can assign a parameter a default value. For example: void MyParameterizedFunction(String param1, int param2, bool param3=false); Does Java support this kind of syntax? Are there any reasons why this two step syntax is preferable?

• Transform any JavaScript function into a page event

  - by Laith

  I need to be able to achieve the following (one way or another): function ShowContent() {} document.onShowContent = function () { // anything I want to happen.... } What I'm trying to do is to add a kind of listener to me Advertisement code on the page that will auto refresh the ad slot when a specific function is called.

• netcon.h not found with mingw?

  - by cftmon

  I am using the mingw(4.4.0) compiler that is included with QT4 and my IDE is netbeans 6.9. i noticed that i can't find netcon.h when i try to include it.I need netcon.h because i need some kind of API to bring up/down a network adapter,and after some googling i found that netcon.h is most commonly used. Linking netcon.h directly from the microsoft sdk produces lots of errors.Or is there some other library to alows me to reset an adapter, or i had to visual C++ completely to solve this problem?

  Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects.

• Web Application Loading Screen

  - by Matt Charlton

  I have a web app that has several tree views. When the page loads i see the unordered lists and after a small latency the styling of the tree is rendered into the DOM. Is there a way to mask the webapp, and have a spinner in the middle of the screen, and when everything on the page is fully rendered the spinner goes away and the mask fades out? Kind of like a semi transparent mask that you would see on a lightbox pop-up dialog.

• File permissions changed between OS X and Windows

  - by Horace Ho

  I zipped a rails project from OS X and sent it to a colleague who works on Windows. He updated the source, zipped the whole project folder and sent the zip file back to me. After unzipping the project, I found that the file permissions information is kind of lost. For example, the script/server is changed from -rwxr-xr-x to -rw-r--r--. Is there a way to preserver the file permission flags, when transferring files between mac and windows? Thanks

• generic programming in C with void pointer.

  - by Nyan

  Hi everyone, even though it is possible to write generic code in C using void pointer(generic pointer), I find that it is quite difficult to debug the code since void pointer can take any pointer type without warning from compiler. (e.g function foo() take void pointer which is supposed to be pointer to struct, but compiler won't complain if char array is passed.) What kind of approach/strategy do you all use when using void pointer in C?

• Tuning SQL Server 2008 for web applications

  - by Kibbee

  In one of the Stackoverflow podcasts, I remember Jeff Atwood saying that there was a configuration option in SQL Server 2008 which cuts down on locking, and was kind of an alternative to using "with (nolock)" in all your queries. Does anybody know how to enable the feature he was talking about, possibly even Jeff himself. I'm looking at deploying SQL Server 2008, and want to see if using a feature like this would help out my web application.
