This bash script will come in handy with my idea of using habak in a
cron job to update the background to my screen every hour:
------------
#!/bin/bash
DIR=~/wallpaper
nfiles=$(ls -1 $DIR | wc -l | tr -d ' ')
fileno=$(( ($RANDOM % $nfiles) + 1 ))
FILE=$DIR/$(ls -1 $DIR | head -n $fileno | tail -n 1)
echo $FILE
------------
Thanks to Joshua Oreman
(http://lists.freebsd.org/pipermail/freebsd-questions/2003-August/016689.html)
for the script. Also, another possible script is randfile found at

WalMart Earth Shoe==garbage footwear
Needed some new shoes two months ago and bought a pair of casual Earth Shoes at WalMart ($26.97). Took a couple of days for the lining to start becoming unstitched. After a couple of weeks the interior heel was completely worn. By now (two months passed) the shoes are flat-soled static generators. I've been psychologically traumatized when I reach for grounded items. Continuous zapping becomes increasingly unpleasant.
Dockers Glacier was the decided replacement. If we had an REI near my place I would've purchased the Dunham Rutland. First day has been pleasant, nice arch support (which was another lacking element of the Earth Shoe). Anyhow, beware the Earth Shoe from WalMart. See it has low price, see it appears gentle on the pocketbook but, lo, it will strike from behind and crush they investment!

MySQL Hibernate and Timestamp issues
Long day trying to figure out a problem with passing a null value on a
Hibernate object that corresponds to a Timestamp field in MySQL. You
can't do it because MySQL interprets the null to mean "insert current
time", and so it does. But, in your sql statement you can place '' and
the column will remain null. After looking through the forums the
general suggestion is the DateTime type to get around this issue.
Because we'll be using Oracle in production anyway (both types map to
Date) this is a moot point--we need to update all of our Timestamps to
DateTime and manually set the values per record.

Jedit macros
Thanks to Scalex in the JEdit community forums, I wrote a bunch of auto completion macros based upon some code he posted. I've saved each of these snippets my ~/.jedit/macros/.bsh and then associated each one as a short cut. That is, to initiate the bracket completion I assigned it to the "[" key as a shortcut. These are really basic and I plan to make updates (especially to the LOG one) as
I have time. For now they work and it's rather slick.
for auto quotes in JEdit:
-------------
buffer_mode = buffer.getMode().toString();
if (buffer_mode.equals("java")
||buffer_mode.equals("xml")
||buffer_mode.equals("html")) {
textArea.setSelectedText("\"\"");
textArea.goToPrevCharacter(false);
} else {
textArea.setSelectedText("\"");
}
-------------
for auto brackets:
-------------
buffer_mode = buffer.getMode().toString();
if (buffer_mode.equals("java")) {
textArea.setSelectedText("{");
textArea.insertEnterAndIndent();
textArea.setSelectedText("}");
textArea.shiftIndentLeft();
textArea.goToPrevLine(false);
textArea.goToEndOfWhiteSpace(false);
textArea.insertEnterAndIndent();
} else{
textArea.setSelectedText("{");
}
--------------
for auto parenthesis:
--------------
buffer_mode = buffer.getMode().toString();

emerge rpm
In the course of getting the Lexmark T632 working on the new Gentoo box we followed the previous post I made a couple months back. There were a couple of things I failed to include the first time. Turns out that to get rpm properly working it requires db3. This can be obtained by emerging openldap (which is something else we needed anyway). Also, the Lexmark installation won't work if you don't have CUPS emerged.

mysql #2
To get the manually-built mysql to startup at boot a script file (that basically wraps the mysql.server script) is required in /etc/init.d. I'll include the script in a future post...
mysql 4.1.3
Needed to get MySQL 4.1.3 working on the new Gentoo laptop and we
downloaded the binary distribution. But it croaked immediately upon
startup with a signal 11. Rather lengthy bug threads didn't provide us
with much information so we simply downloaded the source and built it.
That did it, mysqld_safe now works.

himem needed for laptop memory upgrade
Just received two 1G DIMMs for the old D800 and what to my surprise to see that cat /proc/meminfo only shows 900MB! That was my old amount. Hmmmmm...no good. Turns out, thanks to bcowan on #gentoo, that "himem" needs to be set to 4GB in the linux kernel config or else 900MB is the max recognizable. Easy solution and I'm now cruising with 2026MB. Beautiful.

JEdit 2
Quick way to get the syntax checking on is to create a macro that runs JCompiler. This worked for me because the classpath that I have JCompiler set up with (from maven) will compile the files I'm working on. So all I do is run a macro that saves the buffer and compiles it. JCompiler updates ErrorList with the line numbers of the issues it
encounters. Everything works beautifully.
encounters. Everything works beautifully.
Jedit rules
Okay, I've had it again with Eclipse. It's slow, cumbersome, and drives me nuts with its unresponsive behavior. Several times this week I've completely lost my keyboard functionality. Sure it responds to the mouse and I can navigate, click on menus, etc. But i can't type! Usually I have to either reset the beast or I have to open a model
dialog, then close it, and then the keyboard may work. Either way, I'm jumping back to JEdit.
Several huge plug-ins I got working this morning and absolutely love:
a) Open It. This functions just like the Open Resource in Eclipse: a dialog pops-up, you type in the filename and it matches as you type. This is great because it alleviates the necessity to use the built-in file-explorer in JEdit (which I think is kind of a pain).
b) Dot-Complete. Finally had some inspiration this morning in getting this to work the way I want it. Our projects are Maven projects. How to get the classpath into Dot Complete? Solution is simple, maven -X build-ourproject. Dumps out the the classpath that's created from the dependencies in project.xml. This is great! Now it works and is saving me time and pain of constantly referencing Javadocs.
c) XML/HTML. While I have had this working forever, I simply love how easy it is to create XML/HTML docs in JEdit. It's awesome because it auto-completes closing tabs, shows the hierarchy of the DOM (in relation to the current element) and is overall so fluid. Have yet to find something so simple and powerful. Oxygen is too bloated, Eclipse HTML editor is crap, etc. JEdit reigns in this area.
d) JDiff. This is a beautifully simplistic diff. Nothing else to add. It just works, and functions nicely.
e) Java Browser. If you like the ctrl+o functionality in Eclipse, then this does an adequate job of replicating the behavior. Opinions may differ.
f) Getters/Setters. Autogenerate these by selecting the the variables for which you want them created. Then run the build-in macro.
g) Class Wizard. Rather simple but competent class wizard (for those that like using wizards).

MVC definition
Best definition I've yet to find of the Model-View-Component design pattern:
* A Model that represents application data or state
* The View that processes, formats and renders the display of the Model
* The Controller that is responsible for taking user/client input and
updating the Model

javap and classpath resolution
Having a heck of a time trying to get javap to spit out correct info
for a class that's contained in many jars--it was spitting out the
same thing for each class in the jar (from my script that searches
through the jars for a particular class). After about 10 minutes of
frustration and figuring this out I went to the web and found this:
http://www.ecst.csuchico.edu/~amk/foo/java2tools.html. So, no thanks
to the man page for javap. If the class on which you are invoking
javap resides with the JDK, it'll ALWAYS be decompiled from the JDK
entry. What you need to do is add "-bootclasspath ." to the command
line so that you bootclasspath gets reassigned (to something you don't
care about) to your local dir. Glad this didn't waste too much more
time. Once I get the script completed I'll post it.

importance of having DEVFS in Gentoo
Had a buddy here at work install Gentoo, and he chose dev-sources
which gave him 2.6.7-gentoo-r11. I have r7. Turns out that he *had to
include* dev fs to be compiled into the kernel. The menu states
OBSOLETE, but when Gentoo boots it gives you a warning message if you
don't have it. Without it he could only use terminals (xterm,
gnome-terminal) in X if he was root.
The terminal (gnome-terminal) that he invoked was essentially dead
and was not functional. It loaded a blank, white screen with a
blinking cursor. Took about 5 minutes to figure what he needed in the
Gentoo forums: he needed dev fs. Quick kernel reconfigure, recompile,
copy to /boot, and lilo execution. After a reboot and loading Gnome,
his problem was solved..

Bluetooth, speedstep
I needed to get Bluetooth working so I could toy around with my iPaq
(tossed the Zaurus, too slow and the iPaq is far more aesthetic).
After reading around a bunch of places what to do (mostly at the
Gentoo forums), I reconfigured my kernel and pretty much added all of
the Bluetooth options there are (L2CAP, SCO, RFCOMM, RFCOMMTTY, BNEP,
Multicast filter, Protocol Filter, HCI USB, sco, HCI uart,BCSP). At
the time I also changed my power settings to fix the wierd
clock-synching problem I've been having (since day 1). I enabled CPU
Freq. scaling, ACPI Proccesor P-states driver, Intel Enhanced
SpeedStep.
Bluetooth was easy to get up and running after finally figuring out
that modprobe hci_usb was the only thing needed to get the Dell D800
integrated bluetooth alive. But, since this kernel
recompilation/reconfiguration I've been running noticebly slower.
However, my clock as begun to work. Finally decided to take a look at
the CPU freq today (cat /proc/cpuinfo) and noticed that it's been
capped at 600MHZ! No wonder i've been going crazy with delays. SImple
fix, modprobe speedstep-centrino and the clock is kicked to the max at
1698MHZ (1700MHZ rated).

Multisync
To get multisync to work correctly with Opie Datebook running on the

at least it works. You don't appear to need to do this with the
contact list.

Zaurus pxa255 5600
So I sold my Palm Tungsten C for a Zaurus. And then I bricked the
thing by renaming the wrong file and trying to reflash. Solution was
to get into the Service menu by holding down "d" and "m" while
pressing reset, then powering on (to get out of the Service menu, just
reset). From here you can restore from a NAND flash (4th menu, I
think).
Nice fellow (stormer) from Ireland helped me out by creating two clean
NAND backups from his devices. One an Opie 3.6-pre, the other a QPE.
Both of which I still have and am waiting to post to
zaurususergroup.com for downloads. If you would like this NAND, email
me, securityDOTidentityATgmail.com and I'll make it available.
Secondly, I was able to get the wireless synchronization working with
Evolution using Multisync. I love Gentoo. I didn't need to download
the plugins for this, just typed the following:
USE="evo opie" emerge multisync
Too lazy to add those to my official USE flags. This built the plugins
right into Multisync. Withing minutes everything was up and running.
Love the unit so far. Love being able to SSH and FTP with the thing.
Wireless works wonderfully. Need an SD card for more room.

Tapestry 2

----(begin)----
assets.Content, assets.FontStyles}"/>
----(end)----
So, now all the pages will have the Border component and inherit the style. Plus, the style is easily managable for the designer at the component level.

Tapestry
Okay, so the Home service with Tapestry is HARD-CODED to resolve a blank URL to a Home.page. Well, the beauty of open-source is that you can modify that to your heart's content. I tried that, spent a couple hours on getting it to work and ended up just overriding the service with a local one (extends org.apache.tapestry.engine.HomeService &
Next piece I'm working on is modifying a basic Border component to provide only the shell and specific stylesheets. According to the Shell component you can provide many stylesheets to be applied by assigning an array or collection of IAsset. At this point I'm not sure where I should do that. Should it be in the engine that I define my list? I've got the entries as context-assets, can I just provide that as the expression? Gotta figure it out and record it.

rox-filer key binding
Bothering me that rox-filer default ctrl+n is set to Create New File. So, how to change it to Create New Directory? After scouring Google, #rox, and the mailing list I pieced together the information. You have to have ROX-Session running in order to edit the menu entries. I guess it's assumed in the Help that you do have ROX-Session running.
Of course, it would be nice to just have .roxrc or something equivelant...ROX Faq Keyboard Shortcuts

Lexmark T632 working Gentoo
What a fiasco here at work to get the T632 working in Gentoo, compared with Fedora. It was entirely user error.
So today I decided to give it another shot by downloading the drivers from Lexmark's site. I chose the Suse/Redhat driver because it appears to be the only legit linux driver. Steps for operation:
1) emerge rpm
2) rpm -Uvh --nodeps whateverdrivername.rpm
3) /usr/local/lexmark/setup.lexprint
4) /usr/lexprint/bin/lexprint
The Java app will take it from there. It was a breeze to browse to the T632, create a queue, and print a test page. "gnome-cups-manager" will then have the queue listed, right-click to make default and the setup was complete.
Another completely satisfactory Gentoo experience.

Eterm versus aterm,materm,multiaterm
I've had enough of using aterm and it's variants. I continually find descrepencies in behavior when running jboss and other apps. The terminal will simply vanish and take whatever was running with it.
Eterm appears more solid, just as configurable, and more polished.

Time sync
For some odd reason I've been having time issues when I halt the

# emerge ntp
You need a time server, which can be obtained here:
http://www.eecis.udel.edu/~mills/ntp/clock2a.html
Uncomment the second statement and update the NTP server with your selection.
Add the service to default run-level to startup on boot:
# rc-update add ntp-client default
Start the service now for immediate sync
#/etc/init.d/ntp-client start

Gentoo: Mysql 4.1.3 beta, Openldap
The latest version of MySQL (at the time of this writing) in Gentoo
Portage is only 4.0.20. However, my project at work requires 4.1.1+
for proper behavior. I found this out the hard way after emerging it
from Portage and then building/testing our project only to find a
connection pooling issue. Fortunately, due to the grace of emerge,
unmerging MySQL was painless. Installation of binaries from MySQL's
site was extremely simple and took a matter of minutes to get
everything up and running.
It's not my intention to zealously preach the benefits of Gentoo (or
maybe it is?) , but I do remember when I had a similar problem like
this while running Fedora and I had to go through several steps with
RPMs to set matters straight.
Similarly, what a riotous mess I encountered with getting openldap up
and running in Fedora. This round of installing Openldap, with emerge,
it was a delight. The only change I had to make was adding permissions
for others to write .to /var/lib/ldap so I wouldn't need to be root in
order to CRUD the entries. On second though, I suppose I could've
alleviated that need if I added myself to the ldap group.

ACPI handling for power-button and lid-closing events
Finally have a script for handling the power-button event and
turning off the screen when the lid button is triggered. Hopefully
will soon be able to resolve the issue of suspending and hibernating
(since both are supported in my kernel, 2.6.7-gentoo-r7). For some
reason it croaks reporting some piece of hardware doesn't support the
action...still need to investigate.
Here's the perl script to place into /etc/acpi/handle.pl:

Make sure that it's executable after you create it. Next step is to
update /etc/acpi/events/default:
---begin----
event=.*
action=/etc/acpi/handle.pl %e
---end----
That's it. Now you can shutdown the machine by simply pressing the
power button.
the prerequisite I didn't mention is that ACPI must be compiled into
your kernel and you must have acpid running or nothing here will work.

turning off the screen when the lid button is triggered. Hopefully
will soon be able to resolve the issue of suspending and hibernating
(since both are supported in my kernel, 2.6.7-gentoo-r7). For some
reason it croaks reporting some piece of hardware doesn't support the
action...still need to investigate.
Here's the perl script to place into /etc/acpi/handle.pl:
---begin----
#! /usr/bin/perl -w
use strict;
my $eventarg = shift (@ARGV);
if ($eventarg =~ /^button\/lid$/) {
system ('/usr/X11R6/bin/xset -display :0 dpms force off');
}
if($eventarg =~ /^button\/power$/) {
system('/sbin/halt');
}
---end----

Fluxbox GTK apps and large fonts
Recently installed Gentoo. I'm loving it. Had a problem, though, with
fonts in Fluxbox and GTK apps. Firefox's application fonts (not
rendered HTML) were distastefully large, Eclipse too.
It took me quite some time to track down the real problem. The fix was
a combination of switching the GTK theme to use a specific font
(emerge gtk-theme-switch; /usr/bin/switch2 ) and starting X with the
dpi flag: startx -- -dpi 96. Ended up with this in my .bashrc: alias
startx='startx -- -dpi 96' and now everything looks acceptable.

Up and running
Here's the first post. Don't have much time to write about anything due to time constraints and preperation for the vacation to Oregon tomorrow. Hopefully will have access at the rental place so I can post from there. If not, maybe I'll go "sniffing" around town.
