RPMForge

Red Hat support being four pips less useless than IBM support, I'm forced to admit defeat and merely install SVN using their repository rather than actually activating a test system on RHN. It's all so disappointing to deal with two really obviously technically advanced companies that SUCK at dealing with technical issues on their front lines. With the exception of 1/3 of the IBM personnel I dealt with on the phone this week, most of my experience has been disheartening at best.

Esthers Follies (and Politicks)

Had a great time seeing Esthers Follies, in Austin Texas. However...

Esthers Follies would be much funnier if it wasn't so chock-a-block full of the kind of (hate to use limbaughisms, or the lines of thinking stemming from limbaughnese folk[yaknow, ditto-heads, I still love you, but critical thinking is sometimes lacking in your crowd], because he's a douchebag fat tick of a man, demonstrably, and loves government when it's staffed by his football team of Dicks and Chainsies) exclusively aimed at media-caricature Right Wingers. It's still funny enough to be worth seeing and enjoying for the performers quality antics and delivery, however. And they do poke alot of fun at media-caricature Lefties, don't get me wrong.

Perhaps it's merely a matter of genuineness of delivery coming from an arguably more Lefty bunch of folks with respect to chosen subject matter.

Simply getting at a resource file in a Jar in Java.

Accessing resources in jar files.  I came across a need for this while attempting to not hard code in Java the some data that would be loaded into a HashMap.  The xml in question was conforming to NetBeans default '.ent' file naming.

Sifting through lots of cruft, applet loading specifics and other somewhat useless but informative and educational blather, I eventually ran across http://forums.sun.com/thread.jspa?threadID=5123126 and was rewarded with a straightforward snippet:

use : this.getClass().getClassLoader().getResourceAsStream(name)
example: myClass.getClass().getClassLoader().getResourceAsStream("res/my.gif")

two tips:
1 - use your own class that is in jar file. if used another class - for example Object - fails
2 - name i.e. resource must be without leading '/'

I then repurposed accordingly, since I was assuming XML for my org.w3c.dom.* stuff to parse the config with, I needed an InputStream implementation that could later be passed to the document object I was going to be letting those wonderful modules build for me.


InputStream xmlinstr = this.getClass().getClassLoader().getResourceAsStream("SomeFileAtTheRootOfMyJar.ent");


Reclaim the word Liberal!

"I am a Liberal. By definition this word means "free man". The root of the word is Latin and is "LIBER" meaning FREE. To free a man is to liberATE him. Once he has that freedom he has liberTY. A free-thinking individual would (in a perfect USA) be a liberTARIAN (I have disavowed my membership with this party since the nomination of Bob Barr last ... Read Moreyear). If you freely give you give liberALLY. A soccer player who freely roams the field is called a liberO. Too many people have made this a disgusting word and it is NOT disgusting to be FREE or to want FREEDOM. BE A LIBERAL and help us ALL be liberals, proudly! Rise from the cognitive misunderstanding of this word to the definitive beauty of it and embrace its essence my brother! Semper Fidelis and Semper LIBER!" -- Adrian Scott Parks

Timezone configuration on SLES Linux

Having some trouble with clock drift with 2 SLES 9 SuSE linux boxes. Turns out vmware and the hwclock settings I chose during setup of the OS have been conspiring to put a long drift on my two systems. Fixing it is somewhat simple. Setting it up right the first time is obviously the best solution. To remedy:

Do this stuff to get your time figured out and fixed to where you want from an OS perspective:

Totally stolen from: http://www.planetmy.com/blog/how-to-configure-timezone-on-sles-linux/

The following tutorial will guide you How to configure TIMEZONE on SLES Linux.

Basically you can configure Linux timezone using two methods which is using command or YaST.

Note: use timezone “GMT+0“ for an example below.

For YaST timezone setup, it’s pretty simple. Login to terminal and type:

#YasT Setup

yast timezone

Select Global, select GMT+0
Hardware clock Set To: Localtime
Click Accept.

For command line setup, you’re require to know these 2 files /etc/localtime and /etc/sysconfig/clock.

#Backup existing file

mv /etc/localtime /etc/localtime.old

cp /etc/sysconfig/clock /etc/sysconfig/clock.old

#Edit configuration files

ln -s /usr/share/zoneinfo/GMT+0 /etc/localtimevi /etc/sysconfig/clock

TIMEZONE=GMT+0

HWCLOCK="--localtime"

Bear in mind, you can have different timezone setup for individual or global user by using user profile in your system. For an example,

#Edit configuration file

vi /etc/profile or ~username/.bash_profile
export TZ=/usr/share/zoneinfo/Asia/Kuala_Lumpur

Export “TZ” will overwrite /etc/sysconfig/clock or /etc/localtime setup. Mean that I can use Kuala Lumpur as my separate time zone for particular user in the same system eventhrough my primary timezone setup is GMT+0.

NTP setup
#Edit NTP configuration file

vi /etc/ntp.confserver 0.europe.pool.ntp.org

server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server 3.europe.pool.ntp.org
server your.ntp.server

#Restart NTP Server

rcxntpd xntpd restart

Hardware Clock

#showing hardware clock

hwclock --show

#set the system time from the hardware clock

hwclock --hctosys

#set the hardware clock from the system time

hwclock --systohc

Done!

After doing this verify your clock isn't drifting crazy by using ntpq and lpeers to figure out your clock delay offset and jitter numbers. Seems to work well, saves us some trouble in the future maybe it'll help someone else out of course.

Failing that this thread on the vmware community website illustrates the "clock=pit" option.

SSH Passwordless Authentication

http://blogs.translucentcode.org/mick/archives/000230.html was a great find today. Hail google. Hail clarity in technical documentation.

Keep in mind this is dangerous to do if you don't trust your overall account security, but for my purposes at work it's a great way to get something done.

print "Enter Unix Time Seconds Value Finish:";

Bash Tidbit: environment variables after escaped semicolons

If you find yourself in need of embedding an environment variable in a path directly after an escaped semicolon (something that happens when you have version control tools like Telelogic, which use semicolons as a project toplevel node delimiter) it is possible to merely use backticks "`<around the command>`" to get the desired effect.

Say your default case on the command line to list the directory contents is thus:


ls /mnt/buford/d/teledb/ccm_wa/poobits01/foo.bar\;foo.bar99.99_int/foo.bar/


And you want the 'foo.bar99.99' to be something settable in a shell variable called $REL you then would insert the following to do such a thing:

REL=foo.bar99.99
ls /mnt/buford/d/teledb/ccm_wa/poobits01/foo.bar\;`echo $REL`_int/foo.bar/

Heads and Tails of the last file in a directory.

Screen, act like an xterm

Screen when invoked has a multitude of options, but one that was particularly helpful for me was this:

screen -T xterm ssh user@someunixhost

So as to make the TERM environment variable appear to be xterm allowing vi and other tools to work properly.

Figuring out how to get that into my ~/.screenrc so that it takes affect every time is the next objective. Not many of the hosts I connect to identify "screen" as a TERM type.

Obama's Newbie Activists: Unloved By Insiders But Here To Stay

You should ask those more "seasoned" individuals, who there house is built to serve? Their own well being or the well being of the people of this country? Whether in the Republican or Democrat party, I've found that (with some exceptions in each of course) the established members of each organization are convinced of their own entitlement to lead and control things than they are of operating as an organization of free people acting together in the mass of people that make up the parties interests.

Both parties should lean towards the latter half in future or get more Liebermans and might as well be neocon / pseudodem types in your ranks.

Say It Ain't Jew, Joe

A very effective PAC working in the US to advance the interests of the nation of Israel

* not the people of Israel as about half of Israelis believe the US aids Israel too much, which is saying alot.



You don't have to read conspiracy into it either, it's just a case of one country having a very effective lobbying organization that is getting what more than what it pays for from the US government. That lobbying organization is acting in the interests of hard line militarists in Israel. These folks want to stay in power indefinitely, apparently seeing that the best way to do that is to keep tension high in the region, peace is best kept short lived, military funding is perpetual and plentiful, and best of all we(the US) look like the bad guy.



Lieberman is a friend to them, at all costs it seems.



Contrast AIPAC with JStreet the latter being a more worthy lobbying group IMO. Essentially saying, perpetual shows of "strength" and ever escalating conflict is maybe not such a good idea, go figure.

Meh, more code stuff this time, playing with Perl's FileHandle modules.

Code like:

1. #!/usr/bin/perl -w
   
   use FileHandle;

   if ($ifh->open("< fee.txt")) {
       print <$ifh>;

Apache Commons

Java is an obtuse beast, written by obtuse beasts.

I will be detailing efforts to use the apache commons io framework (DirectoryWalker in particular) in this post.

Apache Commons consists of several helpful extensions to Java in various areas, IO in particular being the one I'm interested, though Math and XML processing code exists for anyone to take advantage of.

Problems that I'm currently working through:

• DirectoryWalker seems to include mechanics for depth limitations, but the default means of shuffling the File objects returned seems to be an Array, the search process itself seems to dive into the filesystem in a chaotic and unseemly way, that does not lend itself to being easily limited to a certain depth.

• Java in general, is somewhat defiant of concrete scrutiny to non domain level experts. So, if one isn't already an expert Java programmer, one cannot take at face value the indications of the documentation for modules involved.

At the moment, I'm determining if indeed I can throw a DirectoryWalker.CancelException and how much more code I'll have to write to do something that is quite simple in a shell script (gnu find, and the parameters --maxdepth --mindepth) in order to mitigate the lack of an ability to constrain a directory walk to an exact distance from a starting point.

From the documentation:

This class operates with a FileFilter and maximum depth to limit the files and direcories visited. Commons IO supplies many common filter implementations in the filefilter package.

Deciphering HPUX 11.0 era compilers and how they tend to fail to build Chinese code (zhchs, zhcht locales) when it is attempted at my workplace, on certain machines.

What this all brings to mind is the tendency of Unix System Administrators to "poison the pool" so to speak by *not* documenting their setups. I'll put this simply for anyone who is a Unix / Linux advocate in todays world of computing, Unix is difficult enough to understand for people who understand it. Throwing shit together and putting it in production with no supporting documentation creates no end of grief when the eventual (and certain) leaving of your job occurs. Unless you want your name to be cursed nigh unto eternity by those that follow you, DOCUMENT YOUR SETUPS AS YOU GO.

Thank you, and good night.
