Current State

Hi! It’s been ages since I wrote here… I’ll try to be better. I now am self-hosting my personal websites as I put a server in a local datacenter recently. It’s something fun, and hardening WordPress is now something more easily doable since I have root on the server. That’s all for now!

This issue came up at work this week. I received two phone calls from customers who were having issues with their Raspberry Pi-based D-STAR Hotspot: something was corrupting the microSD card.

Every year I’ve looked at Anime Weekend Atlanta as more than a chance to hang out with friends from out of town because of the rather unique situation having several laptop wielders in the same hotel room can present. Therefore, I come up with all sorts of hair-brained network schemes to get everyone online from ... Read More

The Importance of VPN Tunnels

Computers, NetworkingLeave a Comment

DEF CON was this past weekend, and in usual fashion, the staff of the convention had projected onto a screen the “Wall of Sheep”: a list of usernames and obfuscated passwords that were transmitted in the clear on the convention’s wireless network. As DEF CON has doubtlessly the most hostile wireless network ever seen, ensuring ... Read More
