When it comes to watching MKV files with embedded subtitles, it often takes a very long time to load the files no matter you use Quicktime or VLC. Here is a simple solution to fix it:
1. Open the Terminal.
2. Type “sudo chmod -R 771 /usr/X11/var/cache/fontconfig”
I don’t actually know why the privilege need to be changed in order to play MKV instantly, but it works like a charm.
As a novice vim user, I found that when I install a new plugin and installed the documentation into ~/.vim/doc folder, but when I try to read the documentation (e.g. “:help NERD_tree.txt” vim displays an error message “E149: Sorry, no help for
NERD_tree.txt”. This can be easily fixed by the following:
:helptags ~/.vim/doc
Recently, I have seriously started using Vim as my main text editor. It’s really cool stuff, because anything based on terminal is awesome 
From today I’ll probably start to post a few hints that I found during the learning of using Vim. The purpose is to share some useful tips, and also keep my own references.
First tip I would like to share to day is to commenting a block of text using Vim.
To uncomment, you can use the similar idea by first block visual select all comment symbol you are using, and then press ‘d‘ to delete the selected. There is no need to press ESC this time.
Apple’s “Back to the Mac” special event has just finished, having watched the partial event video, here are some random thoughts about this event.
About the Lion
I think one of most important things I’m looking for is the sneaky peak of the next OSX release, the “Lion”. We do have a lot of expectations about this release having to see the code name — the King of the jungle. Another thing that is worth looking at is that having the last major architectural improvement from 32bit to 64bit, apple could now concentrate on providing us with new features. The following is some of the new features introduced in this event:
Well, the concept of app store is good. Having one central location for finding and installing all software is really nice. The open source community (e.g. Ubuntu) has been doing this for years. However, since this is the Apple who is doing it. I do have the concern that I need to ‘jailbreak’ a Macbook in order to install softwares. Do note that Steve Jobs said “it’s not the only way for installing apps”, ‘jailbreak’ a Macbook probably won’t that necessary in the near future, but it is a possibility. The app home page and mission control are the very nice small things that Apple is really good at. Making small things really enjoyable to use. The overall feeling is that Lion does not have that much of improvement Maybe I’m asking too much.
About FaceTime
Video chat, Apple introduced this produce like it has never been done before, and they are the inventor of Video chatting. I think this just gets over blowed. I mean, what are the key difference between FaceTime and Skype, and many other softwares that supports video chatting (e.g. gmail, msn, qq etc.)
About TouchScreen
Yes, I completely agrees, touch screen is a useless for note book computers. I mean who wants to have there fingers touching around their computer screen? It makes the screen dirty overtime, and it’s just not comfortable.
Some Little Things
I noticed that in order to watch the event video right after the event. The first browser that is able to do it is Safari. If you’re using other browsers, you just have to wait a bit longer. Here are some screenshots when I was trying to watch the video earlier:
Using Safari on Macbook Pro:
Using other browser (Google Chrome) on Macbook Pro:
I have been using firefox 4 beta on my macbook pro for a while, now there is a bug that is really annoying. To create the bug:
Now firefox window will not show no matter what.
How to make it show again?
Option 1
Connect the external monitor back.
Option 2
Of course your toolbars and controls are reset to the default, at least you can now open firefox without an external monitor.
