Does anyone have any info on changing the hash of a file without corrupting it?
I read about appending a null byte to the end of the file, thus changing the MD5 without corrupting it. Anyone have any info?
The language I wish to do this in is PHP.
Thanks...

If, for example, it's a text file, you could simply insert a space following one of the paragraphs .

First off, a bit of background: I had to do an erase and install about 2-3 weeks ago, so this is a fresh, up-to-date installation of Snow Leopard we're dealing with.
That said, I decided recently to branch out from simply programming PHP in a text editor...

What Mime-type is Safari downloading the file as? What happens if you download it via CURL? Have you tried firefox? XAMPP's web directory is /Applications/XAMPP/htdocs/ not ~/Sites. .

I have noticed that iTunes will sometimes corrupt the odd song in my music library. By "corrupt", I mean that the song seems to get truncated half way through. The metadata (specifically song length) stays accurate, but the song will just quit (and the...

Right click on the files and double check that you haven't set the end time of the song before the actual end time .

This call always triggers...

If this is indeed the case, without having more.
Another possibility is that you are actually corrupting the stack a bit before that point to another heap, your effectively corrupting yours.

Either that's a bug.
Is allowed to corrupt a vector, but it would still be nice if the operation were exception safe of that?
Anyway, whatever it is, I'm fairly sure it should not corrupt memory.

The other thing that springs to mind is software corruption.
There's a chance it's something on the MB, but as it's happened to both kinds of drives, this seems somewhat unlikely .

Hi,
I've inherited a project that at some point creates a zip file, adds an XML file to the zip and then adds a number of PNG files to the same archive. All works fine on the simulator, but whenever I run the same code on the device itself the resulting...

When Xcode builds an application for the device, it alters any PNG resources, converting them to BGRA (as opposed to the usual RGBA) and premultiplying the alpha channel .

For(vector<random>::iterator it = foo.getVector().begin();
The temporary vector is returned when you do foo.getVector() and it gets destroyed the moment ; is encountered after foo.getVector().begin(); Hence iterator becomes invalid inside the loop... .
