DEF CON 27 WiFi Project

Filed under Projects |

Last year, at DEF CON 26, my wife Sunfire and I debuted our Wifi Project in the Jean Vest, fitting the declared 80s theme of DEF CON 26. It got a lot of attention that year and this year, for DEF CON 27, I decided to keep the project going, but to change the project […]

What I’ve learned from the Web Application Security Beginner’s Guide

Filed under Research | Topics covered: , ,

Over the past couple of weeks, I’ve been reading through “Web Application Security – a Beginner’s Guide” from Bryan Sullivan and Vincent Liu (2012, McGraw Hill) with a highlighter in hand. Now that I’ve finished reading through it, I wanted to record some of my thoughts on what I’ve learned, and what I need to […]

** Disclaimer: I’m not an affiliate for anything here, just sharing my honest opinion. ** In an effort to keep working on code, I found another browser game to play with. It’s not as entertaining as my Feed the Snake game, but it’s good practice for looking over code and trying to figure out a […]

HashChecker – a tool for duplicate file detection

Filed under Development | Topics covered: , , , ,

If you are anywhere near as ‘techie’ as I am you have tons of media: thumbdrives, SD cards, hard drives. I even have CDs. I won’t confess if I have floppy disks. Guess. As the year closed out I finally started the massive project of attempting to consolidate all the media I’ve had lying around […]

Linux CLI network troubleshooting in one line

Filed under Development | Topics covered: , ,

Over the years I’ve seen bloated tools and bad how-tos for basic troubleshooting, probably just like you. Earlier this year I got my hands on a troubleshooting flowchart from a company I’d once worked for. It was good that they had developed a process, but I  was astounded at how drawn out it was to […]
