I'm constantly amazed by the power a good idea has over people, the inspiration it creates, and the satisfaction of seeing it come to life... as difficult and rare as that might be.


Here I come again Amsterdam...

Here I come again Amsterdam…

March 4th, 2013

I love the internet. Thank jebuz I’m alive during such an amazing time… truly the dawn of a new age. I’ve been working on an amazing product development project with some fine chaps in the Amsterdam area… and the amazing thing is, we’ve never met in person. I know this is commonplace these days, but […]

Getting HTTPS to work for WordPress when behind a reverse proxy

Getting HTTPS to work for WordPress when behind a reverse proxy

January 4th, 2013

I recently had an issue with https functionality in WordPress when working behind a reverse proxy like Pound or nginx. I’m running Pound, so the solution for me was to add specific proto headers to the pound.cfg file; ## HTTPS listening ports ListenHTTPS HeadRemove “HTTP_X_FORWARDED_PROTO” HeadRemove “X_FORWARDED_PROTO” AddHeader “HTTP_X_FORWARDED_PROTO: https” AddHeader “X_FORWARDED_PROTO: https” ## HTTP […]

How to fix a bum package or force a re-install on CentOS

How to fix a bum package or force a re-install on CentOS

December 2nd, 2012

I recently had a package show up in yum as being installed, but it was not or had been manually removed, so the yum removal process was broken and the ghost package was causing a yum update to fail. The solution was to use rpm to simply and safely remove the entry from the database, […]

Using NFC implant to unlock Samsung Ezon SHS-3120 deadbolt door lock

Using NFC implant to unlock Samsung Ezon SHS-3120 deadbolt door lock

November 27th, 2012

In this video I unlock a Samsung Ezon SHS-3120 electronic deadbolt using my NFC implant from http://dangerousthings.com Great things about the Ezon SHS-3120; – It’s completely self contained and battery powered – It uses only the UID bits of Mifare S50 tags for access control – It leaves memory contents of the S50 free for […]

Security features of the Mifare S50 explained

Security features of the Mifare S50 explained

November 19th, 2012

Combing through spec documents can be a pain in the ass. I recently had to come to a much better understanding of how security features worked inside Mifare S50 and S70 RFID tags, so I put this doc together to try to make the whole thing a little more understandable and easier to read. The […]

Video demonstrating how to read an 2x12mm Mifare S50 NFC compatible tag with a Samsung Galaxy Nexus

October 5th, 2012

This video demonstrates how to get a good consistent read with a 2x12mm Mifare S50 tag and a mobile phone. I use my Samsung Galaxy Nexus to read a glass 2x12mm S50 tag in a sterilization pouch, and read the tag implanted in my right hand.

Video explaining how to get good consistent reads of an NFC 2x12mm glass tag with a typical flat plane NFC reader

October 3rd, 2012

I had some questions from Dangerous Things customers that centered around getting a good consistent read of the 2x12mm NFC compatible tags they purchased. Rather than respond via email, I figured it would be easier to make this video to explain how to get the tag to read consistently when used with typical “flat plane” […]

Let's talk about gun control

Let’s talk about gun control

September 27th, 2012

I don’t own a gun. I want one… heck, I’ve made lists of guns I’d want to buy… but this post isn’t about that. It’s about the absolute insanity of “gun nut” types when it comes to even trying to have a discussion about gun control. So I figured, why not take this gun debate […]

Poor man's DoS attack

Poor man’s DoS attack

September 19th, 2012

I was going through pictures on my phone and came across this one I took of a “poor man’s DoS attack” I was doing to some website for the crime of pissing me off for some likely arbitrary reason. Chrome + the good ‘ol spoon wedging down the F5 refresh key for 30 minutes trick […]

Ron Swanson as an operating system

Ron Swanson as an operating system

September 19th, 2012

I was creating a simple webpage that clients could download a support software package, and I was doing the typical icons for operating systems thing… but I needed an option for no-nonsense web-only support option. I thought “what icon represents the no-nonsense, to-the-point option?” … Ron Swanson! Something about the concept of Ron Swanson as […]
