Locate your mysql_config file and then pass it in the mysql config when you install the mysql gem.

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql-5.1.32-osx10.5-x86/bin/mysql_config

That should address the following error:
sudo gem install mysql
Building native extensions. This could take a while...

You can save highlighted source to a HTML file.
:runtime! syntax/2html.vim

So you can go from something like this:

Ruby Code in Vim

To a html file like this:

The hardest part, for me, was getting the audio transmitter. That’s where avrcp (AV remote control) bit me, because i didn’t know it was a separate profile from a2dp (stereo bluetooth) and then in addition, you’ve got class 1 and class 2 bluetooth devices. class 2 are the “default”, but the range is fairly short and microwave ovens disturb it at work

i switched to a class 1 device, and now i can go upstairs and still have music. Then on top of class 1 and avrcp, you also have to know what media players it supports for the avrcp

(the bluetooth stack, rather; not specifically the transmitter) but the transmitter i got used the toshiba bluetooth stack, which has avrcp but only for a handful of players (not itunes) so if one were to buy a bluetooth audio transmitter, i would say: a2dp, avrcp, class 1, and comes with the bluesoleil bluetooth stack…for windows. i just realized macs probably have builtin a2dp/avrcp and would certainly be compat with itunes.

the specific headset i have is the Sony DR-BT22 and i don’t have any major complaints. music sounds good, it’s reasonably comfortable, and it’s got good battery life. It does have a flimsy feel to it because it’s foldable, but it doesn’t bother me.

the transmitter i have (for the pc) is a Zoom class 2 bluetooth 2. it works as advertised, but i don’t necessary recommend it. it came w/ the toshiba bluetooth stack, which doesn’t work with itunes. so i like the stats of the zoom, but i’d recommend a transmitter that comes w/ the blue soleil stack instead (since it works with itunes).

Example:
rubyconsumer> I like kake!
rubyconsumer> s/kake/cake/

Well it looks like the Skype client for the mac has taken this one step further.  And for once, the mac client is actually ahead of the windows client.

An up to date Skype client will now take that regex and run it against your last message.  The resulting message from the previous example would look like:

Example:
Editted: 10/9/08 7:30AM – rubyconsumer
rubyconsumer> I like cake!

Now that’s Geek Accessibility!

Now if only video sites like youtube would add key board shortcuts…

A few though, need to be configured through secret command line incantations.

I’ve finally ran across a way to add the full path of the directory into the Finder.

defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES

Restart the Finder and volia!

There are more customizations available from the command line here.

Cmd-Shift-/ (aka. Cmd-?)

Now just type in your menu command and the result comes up like quicksilver/spotlight.

Hit enter and volia!

A lot of folks are very reliant on the internet for information. Understandably so, but it doesn’t work in a weak and no wifi situation.

Using gem_server to get your documentation each time seems like a lot of work.

Enter Bashfully Yours, Gem Shortcuts.

By setting up my bash to load up gem documentation, I’m able to get documentation faster then you can off the web.

gemdoc hpricot

Done!

Try it out. It might even inspire you to help out with documenting a few gems.

Having used Block Mode editting in Textmate, I really needed to find a way to do the same in vi.

Volia!

Ctrl-V with ‘c’, ‘I’, and ‘A’ are the magic commands in vi

In a mac environment, I need to add a path for my Ports directories as well as other mac specific configurations. On Solaris machines, I have a different set of configurations.

Managing all of this was getting to be a chore.

So I came up with the idea to use a common profile for all environments with custom profiles for each unique environment.

I’ve been using a low footprint method to running my customized profile for a while now. Luckily, this method also lends itself to the task at hand.

You can than source each profile based on the environment you are in.

In your .profile, .bash_login, or whatever is appropriate, place the following code:

.profile.common contains all my generic configurations.

.profile.mac contains all my mac customizations.

Volia! Instant environment specific customizations.
