Crouching Slave, Hidden Master

by on March 24, 2016

For the past 15 years or so I have run my own authoritative DNS server for all of my domain names.  It started out because back when I was 18 or 19 I ran a small web design / web hosting business which was also a re-seller for a registrar.  At the time it made sense to run my own name servers.  After that business was dissolved, I consolidated my server farm down to one small un-managed VPS for my own personal projects, and just kept running my own DNS.  There was no real reason for me to keep it, but it worked, and I like hosting my own stuff. Recently I started toying with the idea of offloading my DNS to somewhere else.  There are a number of free options that I have access to, but the more I was thinking about it, the more I liked having complete […]

Unicode Font Issue in Windows

by on February 17, 2016

Let me start out by saying that I am not sure if this is a common issue, or a rare issue. My current workstation has been upgraded from Windows 7 > 8 > 8.1 > 10 and I have had a some strange issues crop up, so there is a good chance this problem is somewhat unique. To summarize the problem: Certain Unicode font glyphs were not showing up in certain programs, but displaying fine in others. An example would be that Chrome/Firefox worked fine, but MobaXTerm and Notepad++ did not. The issue was related to Windows Font Fallback and/or Font Linking. The way the issue manifests itself is when you attempt to display Unicode characters that do not exist in the now selected font, they display as missing characters, either a ? or a box. The correct/desired functionality is for windows to fallback to another font which can display […]

Let’s Encrypt with Nginx

by on January 28, 2016

When I saw the first news of the Let’s Encrypt project several months ago I got pretty excited about it, mostly because I don’t like to use self-signed certificates and this blog didn’t seem worthwhile to pay for a proper certificate on.  Combined with the recent news of Google starting to shame sites not using SSL I figured I would give it a shot.  Here is a quick rundown of how I configured my nginx web server to use Let’s Encrypt SSL certificates.  The official documentation for Let’s Encrypt can be found here. A few things to note at the start: I did not use the nginx plugin, as that is very broken I followed a fairly manual process using the “webroot” method thanks to this tutorial My Linux distro is Arch Linux This first thing you need to do is install/configure Let’s Encrypt. You can do this in any […]

Breaking Down an NAA ID / World Wide Name

by on January 20, 2016

At least once a week in my career as a storage engineer I have a conversation that involves a systems admin asking me to add space to a SAN (fiber channel attached) based storage object by referring to it how they see it.  This could be the name of a data store in VMware, saying the “E-drive”, or any number of other descriptions of a storage object which are meaningless to me.  When I ask for more detail I am often given the world wide name of the device, as to them it looks like a pretty unique identifier for the storage they are talking about.  Before I long I log into the system myself and get it all sorted out but I wanted to see if there was a way I could make a quick and easy translation of the world wide name they give me so that it […]

Nano Box Hybrid Review and PAR Analysis

by on September 9, 2015

Introduction As mentioned in my previous post outlining my new reef tank build, the light was one of the things I stressed out over the most.  At the most basic level I knew I wanted to keep SPS primarily, and that I also wanted a hybrid LED/T-5 fixture.  I also knew I would be using a canopy above the tank so whatever light I chose would need to fit inside the canopy, which forced me to exclude most 36″ length fixtures as I did not want to have to squeeze something under the canopy and have it just barely fit.  Coming back into the hobby after over 5 years of not keeping up with the latest technologies forced me to do a lot of research regarding LED technology because when I was last involved in the hobby LED fixtures were not commonly being used.  After a lot of internal debate […]
