Manpage Resume

dave — Sat, 04 Feb 2012 02:29:31 +0000

My resume was getting a little dated, and needed to be updated badly. I’ve gotten sick of the current style of the page (which was done all in HTML/CSS) and wanted to change it up. The result of that is a manpage formatted resume! You can check it out at http://www.daveeddy.com/resume.

The page will automatically redirect to the pdf version of the resume, but if you would like to get the full experience of my resume in your man viewer, run these commands.

wget http://www.daveeddy.com/resume/daveeddy.7
man ./daveeddy.7

Happy hacking!

PS: as a bonus I have pushed out my resume to all of my servers using puppet, so on any one of my machines I can issue a ‘man daveeddy’!

Acer Aspire One + Xubuntu

dave — Sat, 04 Feb 2012 02:23:00 +0000

A couple of weeks ago I bought an Acer Aspire One! It never even made it to the “Welcome to Windows” screen; it was boot up with an Ubuntu USB key. I tried desperately to get used to gnome 3, and unity, and I just couldn’t do it. Besides painfully slow, I’m just not a fan of fullscreen apps, dynamic desktop space allocation, lack of customizability, etc.

After a couple days of that I decided to try out Xubuntu. I wanted to get a Linux experience I was used to, but have a window manager that I actually like using. Xfce has turned out to be amazing! it’s extremely light weight, and it has the full customizability that I loved from Gnome-2.

I upgraded the ram from 1G to 2G, and upgraded the internal 250GB hard drive to a 60GB SSD. After doing some tuning in the system to disable atime, use a different queue scheduler for the disk, and offload the chrome cache directory into a tmpfs, this thing flies. It’s still a little difficult getting used to the small size of it.. but i love it.

Scripts Repo

dave — Mon, 30 Jan 2012 20:43:17 +0000

Check out my scripts repository on github. I have written a bunch of random scripts that needed a home, so I put them up on github! These scripts are put on all of my servers in my ~/bin folder, controlled through puppet.
In the repo you’ll find a flac-to-v0 script that acts just like cp, in that you give it 1 or more source files, and a single destination, and it will convert the given input files (as flac) to mp3. I also have a php rss parser, a shoutcast/df.fm parser/player, and other random stuff, check it out!

Github Account

dave — Sun, 01 Jan 2012 20:06:35 +0000

Check out my github account at https://github.com/bahamas10. Right now I don’t have much code on there, only a single repository for my various dot files. As I write more code I’ll be pushing it up to github, in the works right now is a script to automatically rename mp3/flac files based on their artist/album/song tags.

Puppet Management

dave — Sat, 24 Sep 2011 18:48:26 +0000

Puppet from Puppet Labs is a utility for controlling multiple machines from a single point. It allows for easy server roll outs, as well as keeping multiple servers in the same state. I have a server dedicated for Linux KVM virtualization, and because of this I have spun up about 10 VM’s, so 10 individual Linux installations. I use puppet to make sure that they all have the packages installed that I use on a daily basis, as well as a to make sure that anytime I make a change to my bash or zsh rc it gets populated out to all my servers. Also I store my public key in puppet, so any new server I provision will automatically be populated with it so I can easily SSH into it in a more secure manner.

My virtual servers:

dave@[nexus]:~/$ virsh list --all
 Id Name                 State
----------------------------------
 46 b-puppet             running
 47 b-ssh01              running
 48 codemaster           running
 49 frontend             running
 50 gradius              running
 51 gvoice               running
 52 ldap                 running
 53 ns1                  running
 54 overmind             running
 55 porthose             running
 56 redbull              running
 57 zfs-test             running
 58 skyevm               running
  - template_ubuntu-server-11.04-amd64 shut off

Using puppet I am able to control all of these virtual servers, as well as the virtual host itself, and the storage server that backs it. When I spin up a VM now, all I need to do is install the puppet client and point it to my puppet server and it pulls in the necessary configs to make that VM ready to use.

Puppet Modules:

dave@[overmind]:/etc/puppet/modules/$ ls -1
bwm_ng/
htop/
mini_httpd/
motd/
ntp/
puppet/
users/
vim/

When a new server is provisioned, puppet will insure that some of my favorite packages like htop, bwm-ng, and vim is installed. I also have a module called ‘motd’ that will allow me to easily control the /etc/motd.tail file using the power of puppet templates. NTP is also a good package that I install to make sure that all new servers are synced on the time, so there are no discrepancies in that. Another thing that is key here is I push out the puppet client configs, which will take the puppet client from a default installation, to one that is set to work with puppet in my environment.

Nginx + Apache

dave — Mon, 01 Aug 2011 00:07:45 +0000

This update was in the works for a couple of weeks now, but just a couple of minutes ago I finally pulled the switch, and switched my webserver over to nginx as a reverse proxy for Apache. Nginx can serve up static content faster than you can blink, so that is why it is the first responder to all web requests on 80 and 443. I have a regex line that looks for static content and tells nginx to deliver it without hitting Apache. If the request does not match this regex it will simply be forwarded to Apache to handle it like a normal request.

This update has allowed me to move my webserver from a physical host with 8GB of ram and 2 Intel Xeon processors to a Virtual Machine with only 2 virt cores and 2GB of ram. Putting my server under a stress test I see that I can’t max out the 2 cores, or get the ram to go above 500mb, whereas with the old machine I could max out all 4 cores and get the ram up to 4-5GB’s used.

Atlas Shrugged Part 1 — See it!

dave — Tue, 19 Apr 2011 04:11:15 +0000

I went to see Atlas Shrugged on the Friday it came out and the Saturday after! The movie itself was absolutely amazing, completely faithful to the book and produced exceptionally well for being an independent film.

The casting was done very well, all of the characters in the movie matched up with how I pictured them from reading the book. The acting was great, and the John Galt line making its first run was an amazing scene paralleling the accomplishment of getting Atlas Shrugged on the big screen!

Definitely go see the movie if you haven’t already!

Check out this text document of sed one liners, i’m mirroring it on this website. (thanks for alex levinson for sitting on my couch… where all sed wizardry happens).

New Business Cards

dave — Fri, 11 Mar 2011 04:16:52 +0000

This is the design I have made for my new business cards. I made them using Apple’s Pages, and am getting them printed from http://vistaprint.com. The cards cost me a grand total of (after shipping and tax) $60.00 for 1,000 business cards… which is a LOT of business cards! I orded them a week ago, and according to UPS should be arriving this weekend! Click on the designs to see a high resolution version.
