+title: Raggle Article, RubyGems Signing, Gah People XML-RPC, and More...
+---
+
+<p>
+<a href='http//linuxformat.com/'>Linux Format</a>, <a
+href='http://bsin.org/'>Alonzo's</a> Linux magazine of choice, has a
+brief article about <a href='http://raggle.org/'>Raggle</a> in issue 65
+(April 2005).  They seemed to like it.  Guess I'd better fix the UTF-8
+munging bug before anyone notices (actually, it's fixed in <a
+href='http://cvs.pablotron.org/?m=raggle'><acronym 
+title='Concurrent Versioning System'>CVS</acronym></a>).  I scanned the
+review &mdash; if you're intereste, you can check it out <a
+href='http://raggle.org/files/lf65-raggle_article.jpg'>here</a>.
+</p>
+
+<p>
+Side projects, side projects.  A couple weeks ago, I submitted a patch
+which adds <a href='http://openssl.org/'>OpenSSL</a>-based package signing for 
+<a href='http://rubygems.org/'>RubyGems</a>.  A patch against <a
+href='http://rubygems.org/'>RubyGems 0.8.10</a> is available <a
+href='/files/rubygems-0.8.10-sign.diff.gz'>here</a> (<a
+href='/files/rubygems-0.8.10-sign.diff.gz.asc'>signature</a>).  I also
+wrote up some fairly detailed documentation.  It's included in the
+patch, and also <a href='signing_gems.txt'>here</a>.
+</p>
+
+<p>
+Overall I like the <a href='http://openssl.org/'>OpenSSL</a> support in
+<a href='http://ruby-lang.org/'>Ruby</a>, although I've managed to
+uncover a couple of gremlins along the way, most notably missing methods
+in the <code>PKCS12</code> and <code>ASN1</code> modules.  The single
+biggest problem though, is the lack of documentation; it's even more
+sparse than the <a href='http://openssl.org/'>OpenSSL</a> documentation.
+I've done enough crypto stuff that I was able to slog through it, but
+this is just ridiculous.  It's 2005.  <a
+href='http://rdoc.sourceforge.net/'>RDoc</a> exists for a reason &mdash;
+use it.  I'll resist the urge to comment on the lack of decent <a
+href='http://rdoc.sourceforge.net/'>RDoc</a> documentation, because I
+think <a href='http://pragprog.com/'>pragdave</a> has earned a few gold
+stars.  You know, for that whole <a
+href='http://pragmaticprogrammer.com/titles/ruby/'>Pickaxe thing</a>.
+</p>
+
+<p>
+The <a href='http://gah.pablotron.org/'>#gah people page</a> now has an
+<a href='http://xmlrpc.com/'><acronym title='eXtensible Markup Language/Remote Procedure Call'>XML-RPC</acronym></a>
+interface, which allows you to (say), quickly build a blogroll of
+<acronym title='Internet Relay Chat'>IRC</acronym> people, find people
+in your state, or whatever other pathological idea you can come up with.  
+Full <acronym title='Application Programmer Interface'>API</acronym>
+documentation (including the <a href='http://xmlrpc.com/'><acronym title='eXtensible Markup Language/Remote Procedure Call'>XML-RPC</acronym></a>
+endpoint) is available <a href='http://gah.pablotron.org/api/'>here</a>.
+</p>
+
+<p>
+Speaking of web pages, I really <em>really</em> like the final designs
+on the <a href='http://redhanded.hobix.com/redesign2005/'>Ruby-Lang 2005
+Redesign Blog</a>.  The current <a
+href='http://ruby-lang.org/'><code>ruby-lang.org</code></a> is kind of
+an eye-sore, so the sooner they replace it, the better.
+</p>
+
+<p>
+On the nifty software front, I've been playing with <a
+href='http://openvpn.sf.net/'>OpenVPN</a> and <a
+href='http://venge.net/monotone/'>Monotone</a>.  The former is
+absolutely incredible; it's easy as piss to configure, completely
+customizable, fast, uses <a href='http://openssl.org/'>OpenSSL</a>-based
+X509 certs for identification (both client and server), and as Windows
+support.  Did I mention it's easy to configure, too?  I've been using an
+OpenVPN to tunnel from my laptop to my file server for the last couple
+of weeks so I can mount my <acronym title='Network File
+System'>NFS</acronym> exports read-write over wireless.
+</p>
+
+<p>
+As for <a href='http://venge.net/monotone/'>Monotone</a>, it looks
+really promising, but it's unbelievably slow.  Actually, "ridiculously,
+horribly, unbearably slow" might be more apt.  I know they're working on
+speed, so in a couple of months, I'm sure things will be bearable.  Once
+that happens, I may seriously consider switching over...
+</p>
+
+<p>
+Oh yeah, <a href='http://raggle.org/'>Raggle</a>.  Work continues on the
+0.4 branch. the next stable release (0.4.1) will have the Unicode
+munging behaving properly (hopefully), and a configurable bookmark
+system.  If I get harassed enough, that might be within the next few
+weeks :).
+</p>
+
+<p>
+As for the development version of <a
+href='http://raggle.org/'>Raggle</a>...  Well, that's where all the fun
+is.  Here's a high-level diagram of the various components:
+</p>

+What's new?  <a
+href='http://cvs.pablotron.org/?m=profanity'>Profanity</a> has been
+added to the diagram, and <a
+href='http://cvs.pablotron.org/?m=squaggle'>Squaggle</a> has a new
+dependency, <a
+href='http://cvs.pablotron.org/?m=libsynapse'>Synapse</a>.  Synapse
+is a C-level library that wraps <a href='http://curl.haxx.se/'>Curl</a>
+and <a href='http://cvs.pablotron.org/?m=libfeed'>libfeed</a>.  This
+arrangement has a whole lot of advantages; here's a handful of them:
+</p>
+
+<ul>
+<li>Speed.  C is faster than <a href='http://ruby-lang.org/'>Ruby</a>,
+and the <a
+href='http://cvs.pablotron.org/?m=libsynapse'>Synapse</a>
+<acronym title='Application Programmer Interface'>API</acronym> actually
+passes commands to a child process, so we also avoid the overhead of <a
+href='http://ruby-lang.org/'>Ruby's</a> green threads (and threads in
+general).</li>
+<li>Smaller memory footprint.</li>
+<li>All sorts of great new <a
+href='http://curl.haxx.se/'>Curl</a>-related
+<acronym title='HyperText Transfer Protocol'>HTTP</acronym> features:
+Digest authentication, GSS-Negotiate authentication (eg, Kerberos), NTLM
+authentication (Microsoft), SOCKS5 proxy support, tunnelled proxy
+support, SSL peer-verification control, cookie support (including <a
+href='http://mozilla.org/'>Mozilla</a> cookie jars), and more.</li>
+<li>A complete language-agnostic RSS/Atom parsing, fetching, and saving
+interface.  Write your own interface in whatever language you want!</li>
+</ul>
+
+<p>
+I could keep going, but I just saw the time.  I've got to take a look at
+<code>picard's</code> busted hard drive (yeah, another one), and check
+on <code>kylie's</code> fancy new off-site backups (thanks, <a
+href='http://bsin.org/blog/'>Alonzo</a>!).  Be sure to check out <a
