I am currently archiving and making freebsd-questions, freebsd-hackers, freebsd-stable, and cvs-all available on my website with mhonarc. The lists have been indexed and made searchable with namazu. I have found that freebsd-questions is usefull to people of any *nix platform... You can learn more about FreeBSD at their website.

Matrox PowerDesk

Matrox PowerDesk makes it easy to configure my MatroxG550 graphics card for X11. I love how it makes dual display so simple to set up. You can get Matrox PowerDesk for Linux off of the matrox website.

A.I.N.A.B.: Adam.KungFooHampster.Com Is Not A Blog. I don't like journals and you will never find anything out about my life here. ( update: it has been pointed out to me that this has become a blog... but.. i still won't say anything personal on here... dangit )
Adaptec 2400A or Western Digital 120G Hard Drive?: I have been experiencing some strange issues with my machine during high load times... I posted to freebsd-questions and got a very interesting responce. The whole time I had assumed that the problem was with my raid controller card when in actuallity it may be my Western Digital Hard Disks.
Pong: I know I said that I wouldn't put journal sorta stuff on here, but I just couldn't pass this up. I was playing Atari's Pong and I found a sweet spot! I didn't have to move the paddle!!! It just scored over and over and over and over and over... I found the sweet spot right around when I scored 5 points and I just left it there till it got to 21 and the level stopped. -- time passes -- WOO HOO!!! It left the paddle where I left it! I was able to do it again from the start and get 60 seconds of proof! The madness!! WOO HOO!!
Hi: I will eat your soul.
What Happened to artwiz??: artwiz (or Youngjin Hahn) is someone whom I consider to be one of the best graphic designers right around the turn of the century (2000), and only in the 8th grade. Living proof that open source applications like GIMP could produce professional quality graphics when driven by a professional quality user. I don't know what exactly happened. Did he burn out? He had mastered the art of detail, simplicity, and a crisp modernness that I had never seen before. This ranged from creating amazing simplistic fonts, window manager themes, and music to some sweet desktops. I came across this interview which seems to be at the end of his ambition. After reading it, what can you say? He sounds burnt out. Then I came across his home page which doesn't even mention "artwiz" at all. Maybe its a way of being humble? But, I would be proud to have beared the alias artwiz. Every now and then, I go to his "downed site" in hopes that it will be rebirthed. Cheers to you, artwiz. ... the best damn graphic artist I've ever seen and I don't even know him.

Why is portupgrade so cool?: I personally use portupgrade on my FreeBSD system and have found it to be invaluable. Another slashdot post pointing to onlamp.com has a great run-thru on the power of portupgrade.
CVS Tags - Which should my FreeBSD system use?: The FreeBSD handbook has a great page that explains the differences between all of the different branch tags so that one can decide which version is best for them.
FreeBSD CUPS howto: The FreeBSD Diary has a simple howto on setting up the CUPS (Common UNIX Printing System) server and client in FreeBSD. The message this person posted to freebsd-questions seems to agree. Another thread beginning here helps a newbie get a better grasp on what files to look at, etc for setting up CUPS.

What is Virtual FreeBSD?: This message explains that 'virtual FreeBSD' is simply jails on a FreeBSD system. You can find out more about jails by going to the page on onlamp.com that was discovered on a slashdot post. Of course, the FreeBSD man page on jail is a good resource too!

Apache Module C API: Directory tidbits: I have come across some intersting guideliness if one is writing an Apache Module in C and wants to catch directories with their Sethandler. ( Just imagine a directory as a file of type httpd/unix-directory or DIR_MAGIC_TYPE. )

SetHandler doesn't affect directories inside a <Location> or <Directory> directive. SetHandler does affect all files within those directories recursively.

mod_mime.c's first few lines of its "type checker" immediately rule out directories as r->content_type=DIR_MAGIC_TYPE and returns OK. mod_autoindex and mod_dir will catch this mime type.

This is why the handler of the module I am working on isn't getting a chance. The way my module can get a chance is by implementing its own "type checker". I had it access mod_mime's configuration data and check to see if its cfg->handler matched the name of my module's handler. If it checked out then I changed r->handler to equal the name of my module's handler. I also added another condition to check if the r->uri's last character was a slash("/"). If it wasn't a slash then I returned DECLINED so that mod_dir would redirect it to the appropriate path.

The reason I had to do this is because every module's type checker gets a shot to change the attributes of a request object. It gets called every time there is a hit to apache and does not care if you defined a SetHandler inside a <Location> or <Directory> directive. I needed to know that the object being requested was within the bounds of a SetHandler(cfg->handler) with the same name as my handler handler. I found this out the hard way when every virtual host on my site ended up with a blank page because I assumed that my module would only be called within a SetHandler directive and that I wouldn't have to verify.

I hope someone out there finds this information useful because I wasted a lot of time looking in the wrong places to solve my problem.

Client Side XSLT/XML Inernet Explorer & Netscape/Mozilla/Firefox

HOW can I get mozzilla and IE to render xml pages with xsl in similar fashions?

XML's xml:space="preserve" is an attribute that will tell a tag to preserve whitespace and linefeeds
XSL's <xsl:preserve-space elements="tag"/> is a xsl tag that will tell the xsl processor to preserve whitespace and linefeeds for the specified elements (white seperated list)
XML's second line! <?xml-stylesheet type="text/xsl" href="template.xsl" alternate="no"?>
XSL's <xsl:stylesheet ... >
1. omit-xml-declaration="no" -- keeps the <?xml version="1.0"?> at the top of the output. -- tells IE to respect xml:space="preserve" among other things.
2. indent="no" -- prevents IE from getting confuzed with whitespace if you have white-space: pre CSS usage being processed on the outputted HTML.
3. method="html" -- tells mozilla to process this output like html (obviously it doesn't do anything intelligent with media-type, doctype-public, or doctype-system ... they're just output ... not instructions like method
4. media-type="text/xml" -- tells IE to use this document like an XML document... so that it will respect the xml:space="preserve"'s
5. doctype-public="-//W3C//DTD HTML 4.01 Transitional//EN" -- we can't use xhtml because method="html" doesn't make self ending tags like <br/>
6. doctype-system="http://www.w3.org/TR/html4/loose.dtd" -- we can't use xhtml because method="html" doesn't make self ending tags like <br/>

To see this page as XML processed against XSL on the fly with both IE and MOZ ... clicky ... clicky ...

XSL-FO and FOP and white space (converting XML to PDF)

I never realized what an issue white space was until I started using, xml, xsl, and fo.

If you want the same effect as the HTML <pre> tag in FO then in your...

XML make use of the xml:space="preserve" attribute
XSL make use of <xsl:preserve-space elements="tag"/> instruction.
FO
1. FOP make use of the white-space-collapse="false" and linefeed-treatment="preserve" attributes ( warning: Due to a bug in current versions of FOP, setting white-space-collapse="false" will also preserve line breaks in the text. Do not rely on this behavior, as it is non-conformant and will be changed. ) - meaning.. always set linefeed-treatment ... don't make assumptions
2. Other FO engine consider FOP's primary way of preserving whitespace and maybe try out the white-space-treatment="preserve" attribute

Remember... WHEN IN DOUBT - W3C!! ( XSL-FO ) ( XSLT ) ( XML )

To see this page as REALLY ROUGH BETA PDF OUTPUT (proccessed by FOP) ... clicky ... clicky ... ( and please remember ... if this output is ugly, its my fault ... not FOP's )
