A nice and layman introduction to encryption as used for digital signing, based on private/public keys and Certification Authorities (CA), and how that relates to the upcoming Gatekeeper security feature of Mac OSX Mountain Lion (10.8).
An excellent round-up of the current solutions available to install NTFS read/write support on MacOSX 10.7.x Lion (in case, for some sad reason, you really have to deal with NTFS filesystems ;-)).
A good description of the differences and usage of these two useful command line tools.
I kinda of understand why Apple decided to hide the ~/Library folder when using Finder: they probably noticed how much user support they were wasting because people end up deleting the Library folder from their user account.
Anyway, it’s nice to have a way to get it back visible in Finder in Lion:
chflags nohidden ~/Library
This command can be used to hide/unhide any folder. Neat.
In case you use Omnifocus (I totally dependent on this piece of software to put some order in my life and actually GTD ;-)), it’s nice to know that there are some beta revisions released quite often by the Omni developer team that may fix some issues with the most current stable release.
I’ve just “fixed” some annoying bugs in the most recent stable version (19.2.) in Lion, and got some new Lion specific features (e.g full screen). I’m probably getting some brand new bugs too, but so far, I like living on the bleeding edge 😉
