Windows memory dump options
From Microsoft’s KB:
阅读全文…You can configure Microsoft Windows 2000, Microsoft Windows XP, and Microsoft Windows Server 2003 to write debugging information to three different file formats (also known as memory dump files) when your computer stops unexpectedly as a result of a Stop error (also known as a “blue screen”, system crash, or bug check). You can also configure Windows not to write debugging information to a memory dump file. Windows can generate any one of the following three memory dump file types:

junsu and I have discussed about some big hacks to FreeBSD kernel, and the implementation of a minidump is a good idea, I think.

I finally understood what he want, according to his post today:
" Hey, here’s an idea… using the VFS wrapper idea our
‘ports’ system could create a namespace that makes everything

simply run the program you want to run and our package manager
would download and install it on the fly."
Dillon's commit!
Despite being hurt in an accident, he finally committed the newtoken commit to DragonFlyBSD!!

Scott Long today announced the release. This is a point release over 5.2-RELEASE which addresses many critical bugs.
The -CURRENT have already differentiated from the RELENG_5_2 branch, say, 5.2.1-RELEASE by this time. The most significant differences are:

Profiling based optimization means better performance.
Here’s phk’s suggestion:
We can compile our kernel with "--test-coverage --profile-arcs" to
do basic-block profiling (see kernbb(8) and gcov(1)/gcc(1) docs.)Announcing FreeBSD 5-SELECT cvs repository
