Advapi32 Patch for Windows XP 64-Bit

As usual, here is the patch of advapi32 on Windows XP 64-Bit that enables testing of CSP dlls without Microsoft signature. In this platform, there is two versions of this dll : on in the System32 directory that is the real 64-bit one, and one in the SysWOW64 directory that is the 32-bit one. So, we have to patch the two dlls. You'll find below the usual patch description for each one of them. You may notice that two have an identical version number, 5.2.3790.1830, that is the same for advapi32 on Windows 2003 SP1. This is why the patch for the SysWOW64 copy is identical to the one on Windows 2003 SP1.

UPX universal binary for Mac OS X

As the buzz is mounting on the Mac OS X platform these days, I decided to buy one and start hacking. On the Windows and Linux platforms, I'm used to compress all my binaries using UPX, thus saving space and bandwidth. Unfortunately, when I tried to download a version of it for Mac OS X, I couldn't find a single link, even on the official web site. So, I decided to compile a version myself. The task was not straightforward but I was able to build a universal binary Mac OS X 10.4 and 10.5. It should work on 10.3 but I didn't test it. The result can be downloaded from the link below. I hope this will help. http://www.idrix.fr/Root/MacOSX/upx-3.02-universal-macosx.tar.gz
