Long Running Query

New Site: www.GetNS.Info

Sun, 14 Dec 2008 20:44:10 -0500

I've setup a new site, www.GetNS.Info. This site is intended to let you look up an IP and, if it's a nameserver, determine what domains it hosts. I also plan on keeping historical information on each server I come across.

debugsources.list: No such file or directory

Tue, 18 Nov 2008 09:16:18 -0500

I was getting "debugsources.list: No such file or directory" errors. Turns out I was moving the BUILD dir to the BUILDROOT. Copy, don't move. Once I changed mv to cp in %install it all worked.

error: Unable to open temp file.

Fri, 31 Oct 2008 09:18:03 -0400

Got this error while a script was building an RPM:

RPM build errors:
Unable to open temp file.
error: Unable to open temp file.

Turns out the permissions of /var/tmp were wrong. I did a 'chmod 777 /var/tmp' and 'chmod +t /var/tmp' to fix it. You can check what rpm's tmp dir is by running 'rpm --eval %_tmppath'.

Reasons I Dislike MSSQL

Wed, 29 Oct 2008 09:30:52 -0400

1) No MD5/SHA224-512
2) No indexing of varchars
3) It's slooooow to access via freetds+pymssql

Most of the talks were boring. I did enjoy Ian Clark's presentation on predicting people's behavior. :(

I'm not sure if I love the fact that I, as root, can't do anything. But not being able to run .bash_profile when I log in is a *bit* annoying. Plus I cant reboot or anything else without changing contexts.

4chan On My Chumby

Sun, 23 Mar 2008 18:47:07 -0400

My Chumby now displays random images off of 4chan's /b/. I ended up using a pre-made image displaying widget and then writing my own spider/parser/XML output engine on www.lulzlunch.com. Anyone can use it by enabling the PhotoFrame widget with the URL set to "http://www.lulzlunch.com/images/b". It now auto updates about once every 12 hours. An automatic resize is in place. I should have a chance to test it on Wednesday.
-Paul

Update: It's been working great for a while. You can even view random images from your browser. There are instructions at http://www.lulzlunch.com/index.py/chumbyinstructions

Sorcerer's Apprentice Syndrome

Ah, the newest techie thing I've learned:

Sorcerer's Apprentice Syndrome

Defiantly worth reading. If only for the brilliant Disney reference.

Uber Geek Moments In My Life

Thu, 05 Jul 2007 02:19:01 -0400

- Writing software for an amateur radio balloon
- Making a VIM vs Emacs joke and then being drawn in to the resulting discussion. This all took place on a MUD
- Researching routing protocols for use on a network of wifi routers using ham radio power levels. The goal being to create a very fast, redundant, emergency communication network.
- Participating in Defcon CTF quals.
- Instigating an argument about who is better in World Of Warcraft: Chuck Norris, Jack Bower, or Ven Diesel.

I'm sure there are others I'm not thinking of.

Count The Buzzwords

Sat, 19 May 2007 22:28:36 -0400

The following code is a recursive function that pulls data out of a Python xml.dom.minidom object using a list of lambda functions for selection. Its object oriented and functional using XML, DOM, scripting, dynamic typing, recursion, and Python. Its also a bastardization of the proper way of using XML. I'm sure I could include some closures and other fun stuff if I wanted.

>>> def walk(lst,dom):
	if len(lst)<=0:
		return dom.nodeValue
	match=lst.pop()
	errors=''
	for i in dom.childNodes:
		if match(i):
			try:
				return walk(lst,i)
			except KeyError, msg:
				errors+=msg
	if errors=='':
		raise KeyError, "Nothing found at %d "%len(lst)
	raise KeyError, errors

>>> walk([
	lambda x: True
	,lambda x: x.nodeName==u'VALUE'
	,lambda x: x.nodeName==u'PROPERTY'
	,lambda x: x.nodeName==u'INSTANCE'
	,lambda x: x.nodeName==u'VALUE.NAMEDINSTANCE'
	,lambda x: x.nodeName==u'SEF.MANAGEMENT.OBJECTS'
	],dom)

Let me know if you think of any more buzzwords.
