Main Page

Hey, another wiki. Great!

Here, you will find things. You may notice that anonymous edits are firmly DISABLED. Yeah, THAT'S RIGHT. I am intentionally destroying the communal benefits that wiki was designed to provide. Why? I friggin hate spam, and my two previous wikis were consumed by friggin spambots. You may also notice that you can't create a user account. COPE! :) If you really want to contribute, please mail me at dreNOSPAMPLSKTHX@mac.com, and I'd be more than happy to let you in.

Here is the page of User:Dre, your esteemed information broker.

Scripting

Here's where I keep a bunch of scripting snippets / examples. This includes:

• Basic shell scripting idioms (tests, loops, redirection)
• zsh profile elements
• AppleScript Droplet example
• Perl scripts

Useful Commands

Some useful and often Mac OS X specific commands. So far:

• Using dd to rescue data from a dying disk
• Encypted and growable disk images
• perl one-liner for global find / replace
• finding the input device idle time from ioreg

TigerPage

This stuff is all specific to Mac OS X 10.4, Tiger. Some items discussed here:

• launchd
• dummynet

Network Stuff

• iTunes Remote Streaming details the process for using iTunes music sharing across a WAN.
• AS / Routing Research includes information about determining the number of discrete logical paths in and out of an Autonomous System (AS)
• TCP Timeouts shows some sysctl configuration for adjusting TCP window sizes.
• xinetd, ssh and netcat is a xinetd configuration example showing how to use xinetd to trigger ssh / netcat on demand to encrypt pop3 traffic.

Servers / Hosting

I once maintained a FreeBSD box in colo. Check out the page of meta, where I have notes and instructions for the various services I was running.

Installing and using unix software in userland

In your shell init file, set the following (for bash / zsh compatible shells):

export LDFLAGS='-L/path/to/your/home/lib'
export CPPFLAGS='-I/path/to/your/home/include'
export PATH='/path/to/your/home:$PATH'
export LD_LIBRARY_PATH=/path/to/your/home/lib
export LD_INCLUDE_PATH=/path/to/your/home/include

Log out / in, so that the above takes effect.

• Configure any dependencies with --prefix=/path/to/your/home, and make / make install as usual. They will be installed into your home directory (~/lib, ~/include, ~/bin)
• Configure your desired software with --prefix=/path/to/your/home and make /make install as usual. It should pick up all your new libs / includes due to the environment variables.

When you execute your new binaries, they will be able to find your userland libraries thanks to LD_LIBRARY_PATH.

How to make and apply patches

Once you have the needed changes, apply them (pre autoconf) to a copy of a fresh source directory. You should now have a 'patched' directory sitting alongside an unpatched direcetory. Now generate the patch...

diff -ruN old new > my_patch

To apply this patch to a fresh source directory, place the patch alongside the source dir:

patch -p0 < my_patch

... and then of course, the requisite links to the mediawiki docs, hosted at wikipedia:
