So as you may be aware, I developed SelfSolved in order to avoid cluttering up this blog with “I fixed this!” posts. I’m trying to get into a habit of writing at a higher conceptual level, instead of this repository being just yet another technical problems blog. It turns out that without writing [...]

fixing a scrambled IPython command history on stock OS X 10.6
So I started over with a fresh install of OS X 10.6 recently, and wanted to restore my Python development environment. In doing so, IPython is absolutely essential if you want a sane interpreter environment to test out code. I had a bit of trouble with it though.
The Problem
The stock Python 2.6 shipped [...]
Subversion 1.6.2 runtime error on network access on OS X 10.5
A new SelfSolved solution is up for perusal. The problem I tried to solve:
After compiling Subversion 1.6.2 from source on OS X 10.5 Leopard, the compilation is apparently successful, but svn dies when it tries to connect to the network for the first time. Crash log reports that symbols are missing from libneon.dylib.
Crash report [...]
finding a fault-tolerant HTML parser for iPhone SDK
A new SelfSolved problem is ready for perusal:
A couple of my iPhone projects require a decent HTML/XHTML parser. On OS X, Cocoa ships with NSXMLDocument, which includes dirty HTML parsing functionality from libtidy. Unfortunately, NSXMLDocument is not part of the actual iPhone 2.2 SDK (though it is part of the 2.2 Simulator — so it’ll [...]
MenuMeters integer overflow in memory stats
MenuMeters is a very cool, free (as in freedom) system monitoring tool for OS X that sits in the menu bar and shows you live statistics, including such values as current bandwidth usage, current network activity, memory usage, page faults, etc.
One thing that has been irritating me lately is that there’s a cosmetic error MenuMeters [...]
SSH, Subversion through SOCKS proxy on Mac OS X
One persistent problem that I run into is that I need to access certain network resources through a SOCKS proxy server. This is all well and good if they are web resources — Safari, Firefox, etc. support SOCKS proxies quite well. However, I also need, for example, SSH and Subversion access to some [...]
Fixing undefined library symbols for compiling PHP 5.2.8
So while compiling PHP 5.2.8 on OS X 10.5, you might run into something like:
Undefined symbols for architecture i386:
“_xmlTextReaderSchemaValidate”, referenced from:
_zim_xmlreader_setSchema in php_xmlreader.o
“_xmlTextReaderSetup”, referenced from:
_zim_xmlreader_XML in php_xmlreader.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
Undefined symbols [...]
Testing a POP3 server via telnet or OpenSSL
Sometimes you can’t be bothered to install and setup a command-line mail client and/or VPN, but you still need to access a POP 3 server from a remote machine. Sometimes you just need to know if a POP3 server is working or not. As a largely text-based protocol much like the HTTP protocol, [...]
Building from source package on Debian / Ubuntu to fix sudo PATH issue
So I’ve been kicking around an Ubuntu installation, hoping to replace my aging Fedora 5 deployment. Last time I touched a Debian distro was…well…sufficiently long ago that it’s more or less all new to me.
What’s less new is the sudo path inheritance issue — this one’s been around. Ubuntu’s sudo hard-codes its PATH [...]
