Fix for slower startup and shutdown times since Snow Leopard 10.6.1

Ever since I upgraded to Snow Leopard 10.6.1, my MacBook Pro startup and shutdown was much slower than before.

I searched for a quite a while on forums to find the solution, but nobody seemed to know a solution. I finally figured out what it was. It seems that somehow the ownership of my startup volume's root directory (/) wasn't assigned to the root account anymore, but to my account instead. This made the kernel prelinking fail since it requires that root is the owner.

This is how you solve this after launching the Terminal app:

sudo chown root:admin /
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches

You'll have to enter your password after the first command.

Hope this helps someone, since it was really frustrating to have these slower startup/shutdown times for me.

ScreenFlow : Finally a Mac screen capturing app that kicks ass

I've been recording all my screen casts with SnapzPro and then re-recording them with Camtasia Studio on Windows to be able to edit them. This is to say the least, extremely tedious.

Yesterday I stumbled into ScreenFlow, an all-in one screen recording and video editing application with very cool features like call outs, video actions, key press display, etc. You can even capture audio from multiple sources and record your iSight at the same time as doing your screen cast. Afterwards you can combine them by manipulating the individual tracks and for example get a cool narrator call out that sits in a corner of the screen cast.

I also like their approach towards the recording operation itself. You don't have to constraint yourself by deciding which area of the screen has to be recorded beforehand. With ScreenFlow you just record everything and crop it in the editor afterwards. They are using a custom algorithm that only records changes that appeared on the screen, so even my 2560x1600 resolution was recorded together with audio and the iSight video, without any sign of a hick-up. I love it!

It might be a tad on the expensive side ($99), but considering the functionality that you get, I don't think it's exaggerated.

SvnX ... at last a great Subversion GUI for MacOSX

I just finished explaining my girlfriend how to use Subversion and thought I'd check up on the status of the GUI clients out there. After some searching, I stumbled into one I had never seen before, and it looks great! It's called SvnX and you can get it from here.

It's very close to what I had been looking for since the beginning. It even offers repository browsing and checkout. Another nice touch is the integration of Apple's FileMerge, which is one of the nicest diff and merge utilities that I have ever seen.

At last I will not have to regret the Bitkeeper GUI tools anymore!

Quick note for those that have been searching, you can access the Tiger search directly by pressing F5.

Quicksilver ranks amongst the most useful apps ever

I've been looking for an easy and lightweight way to launch applications after certain keyboard combinations. Most applications I tried were much too heavy and did way too much.

Then I stumbled into Quicksilver. I doesn't do what I was looking for at all, but instead it offers a new paradigm that feels perfectly right after using it for a little bit.

Instead of having to define shortcuts for all the applications that I'm interested in, it indexes all applications, addresses, bookmarks, scripts, sherlock channels, music files. You access Quicksilver by pressing Command-Space and it provides you with a very cool transparent dialog where you can type in characters. According to the characters you enter, it looks for entries in it's catalog and offers you the possible actions that can be executed upon a match.

I also suspect that it intelligently remembers what your most common actions are and proposes those first. So to launch a Terminal, I just press Command+Space T Enter, for Mail this is Command+Space M Enter. Now I don't have to spend time trying to figure out which keyboard combination would be the most suitable, I don't have to configure them and I don't have to remember them. Also, if any new applications are installed, it instantly knows about those and I can start using them.

It always great when people try to offer innovative solutions for day-to-day problems. :-)
