Adding a file system hierarchy into a CVS module I had a whole bunch of code that needed to added to a CVS repository. Normally with just a new directory or two and a few files, doing "cvs add" for each one is no big deal. But when there's a whole file system hierarchy that can be a real PITA. This is where "cvs import" comes in handy.

I usually only use "cvs import" to create a new CVS module but it can also be used to do a "bulk add." Maybe it's common knowledge for CVS jockies but it's easy to forget about unless oft-used. Here's the scenario:

There, that's a lot easier than individually adding directories and files.

Editing Perl with Eclipse and EPIC I've been bouncing between development in Perl and Java a lot this, two languages that I both love and loath at various times. One of the things that I love about developing in Java is using Eclipse. This week I decided to give the Eclipse support for Perl a spin. Well, I'll be saving my love for the Java support.

The only gripe I've heard about Eclipse that I haven't had a good answer for is the absense of Emacs key bindings. Otherwise, what's there not to dig about Eclipse?

Dollar costs
Support for refactoring
renaming and changing method signatures, moving them around... all with dependent references kept in tact
Extracting interfaces
OK, that falls under refactoring but worthy of its own mention
Source and javadoc stub automation
Spontaneous method stub creation, constructor and accessor creation, javadoc stubs
Test case generation and running
JUnit and ant awareness, yum
Syntactical and semantic error highlighting
Fixing errors early and often is easy cause they're usually obvious

I was hopefull that the EPIC plugin would provide at least some of those things for Perl development. This is what I found:

OK, that's a pretty good start. But some things I wanted like syntax completion (i.e. when editing Java, you can type "for", hit shift-space to pull up options to loop over an array or a Collection and voila: a for loop is materialized. ...so basically all of the goodness you get for Java development is lacking for Perl. Nonetheless, I think it's a promising start. I'll be trying the EPIC updates from time to time as new occasions to develop in Perl present themselves.

In the meantime, you can enjoy the fruits of this week's labor by pulling it off of CPAN; that's where you can get WebService::Technorati. It's also part of the latest release of the Technorati web services SDK. Thanks to David Wheeler for turning me on to Pod::Simple::HTML ...I'm still trying to figure how he gets it to output nice docs from pod, mine didn't come out nearly that purty. Ah well, I guess that'll be part of next week's Perl fun.

XML::Parser on Mac OS X I needed to fiddle with XML::XPath on my powerbook today, it depends on XML::Parser. Complacent with how most unixy things I want to do JFW on Mac OS X, I dropped down to my CPAN shell and typed "install XML::Parser" -- bzzzt!

It turns out that expat is not installed, grrr. So I fired up Fink Commander and had it gimme some expat lovin'. Tried it again -- bzzzt! This is what I did in the CPAN shell

cpan> o conf makepl_arg "EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include"
cpan> install XML::Parser
-- ding-ding-ding! We have a winner! XML::Parser installed! Thereafter, XML::XPath JFW'd and I'm on my way.

Tomcat's "Content-type" header parsing busted? One bit fun this week was trying to figure out why some XML output I was working was mangling characters. I thought I was doing all of the right things as far as handling the data goes. Well, I think I was but Tomcat 5.0.28 wasn't.

I poked around the Jakarta bug database and the only mention I could find that close was PR 31442, which described having this

<%@ page language="java" contentType="text/html; charset=UTF-8" %>
<%@page pageEncoding="UTF-8"%>
and saying that the text was coming back ISO8859-1 when the page is requested as a GET but not as a POST. Well, someone from the Jakarta project marked the bug INVALID glibly saying to ask on the user's mailing list and look at the Connector configuration because it's not a bug. WTF? Are you kidding?

Now I looked around in the Connector stanza's that come in the server.xml and see no mention of encoding configuration attributes. I've got a real simple test case.

<% response.setContentType("text/xml"); %>
triggers no funny encoding behavior, I get the data out as good old utf8 just as I wanted but if I did this
<% response.setContentType("text/xml; charset=UTF-8"); %>
....kablooey! Mangled encoding! That's just wrong. And if it's not wrong, I think it warrants a better answer than RTFM on the Connectors.

And the problem may not just be isolated to JSP handling. Judging from other reports that are turning up in Google's index pertaining to SetCharacterEncodingFilter, it's affecting the filter implemetation as well.

What are all of these stupid people doing in my country? There were some severe system problems last week that pretty much knocked this site out of commission, I'm hoping it's all in the past now.

In the meantime, the Big Lie that waging war on Iraq has some relationship to 9/11 and terrorism apparently has been successfully Jedi mind-tricked into the American psyche and we're destined to have four more years of high crimes and misdemeanors. It just makes me wonder what is up with the rest of the country. Plenty of folks abroad are, evidently, equally perplexed by this election, as we see in a recent Daily Mail cover.

If you're single, there are some Canadians offering asylum. I'm thinking of packing up the family and moving to New Zealand or something.
Just to keep track of where I don't want to be, I'm reckoning with the map:

electoral college strong kerry Strong Kerry (146)
electoral college weak kerry Weak Kerry (37)
electoral college barely kerry Barely Kerry (69)
electoral college tied Exactly tied (0)
electoral college barely bush Barely Bush (30)
electoral college weak bush Weak Bush (66)
electoral college strong bush Strong Bush (183)
Needed to win: 270
Do you live in a state of stupity?
Apparently 59,054,087 of you do.

  State Avg. IQ 2004
1 Connecticut 113 Kerry
2 Massachusetts 111 Kerry
3 New Jersey 111 Kerry
4 New York 109 Kerry
5 Rhode Island 107 Kerry
6 Hawaii 106 Kerry
7 Maryland 105 Kerry
8 New Hampshire 105 Kerry
9 Illinois 104 Kerry
10 Delaware 103 Kerry
11 Minnesota 102 Kerry
12 Vermont 102 Kerry
13 Washington 102 Kerry
14 California 101 Kerry
15 Pennsylvania 101 Kerry
16 Maine 100 Kerry
17 Virginia 100 Bush
18 Wisconsin 100 Kerry
19 Colorado 99 Bush
20 Iowa 99 Bush
21 Michigan 99 Kerry
22 Nevada 99 Bush
23 Ohio 99 Bush
24 Oregon 99 Kerry
25 Alaska 98 Bush
26 Florida 98 Bush
27 Missouri 98 Bush
28 Kansas 96 Bush
29 Nebraska 95 Bush
30 Arizona 94 Bush
30 Arizona 94 Bush
31 Indiana 94 Bush
32 Tennessee 94 Bush
33 North Carolina 93 Bush

38 New Mexico 92 Bush
39 North Dakota 92 Bush
40 Texas 92 Bush
41 Alabama 90 Bush

43 Montana 90 Bush
44 Oklahoma 90 Bush
45 South Dakota 90 Bush
46 South Carolina 89 Bush
47 Wyoming 89 Bush
48 Idaho 87 Bush
49 Utah 87 Bush
50 Mississippi 85 Bush
There you have it: the closer you are to the coasts or Lake Michigan, the more likely you're not a dumbass.
I was never particularly enamored with John Kerry, in fact I would've been happy with a Wesley Clark-Howard Dean ticket. Nonetheless, I don't think Kerry would have been so driven to a war that he would have disregarded counter-indicative intelligence and the advice of allies to wage one.
Another idea that no longer seems entirely ridiculous is to secede from union. Seriously, who wants to be part of this country when California's vote is under represented in the electoral college and yet our youth are being sent to Fallujah to wage war against a culture and people most people here know little of. We're the country's vegetable stand and it's cannon fodder. I don't think so. Suddenly, Ecotopia sounds like a reasonable proposition.
Independence for California!
