Speaking at WordCamp Charleston

Just got confirmation that I will be speaking at the inaugural occurrence of WordCamp Charleston in May. WordCamps are informal, community-organized events that are put together by WordPress the user community. Everyone from casual users to core developers participate, share ideas, and get to know each other.

Wordpress Security at WordCamp CharlestonThis WordCamp will be a one-day event, May 17, held at the College of Charleston, and promises to focus on quality content covering all topics relating to WordPress, from a beginner level to developer sessions, and much more.

I will be speaking on WordPress security. As WordPress becomes one of the most used content platforms on the web it increasingly comes under attack by those wishing to either take control of sites or and just take them down. To keep sites from being compromised it is important to have a good understanding of how WordPress operates and what your options are. In this talk I will cover topics ranging from installation and setup to user accounts and updates.  We will also talk about backup and recovery and what you can do if your site is attacked.

This talk is aimed at anyone running WordPress.org on shared or self-hosting and will give specific steps and examples that you can take to secure your site regardless of  your experience level.

For additional information on the conference, speakers, sponsors and registration, please check out the WordCamp Charleston website.  And if you are in the Charleston community and interested in WordPress, please consider attending one of the monthly Charleston WordPress User Group meetings.

JMRI, Raspberry Pi, SPROG

My mind is turning in odd ways – thinking of using something like this connected to a Rasperry Pi (cheap small Linux computer) running JMRI and wireless. That could then be controlled remotely using VNC and also support iPhone type based Raspberry Pithrottles. I already have the Raspberry Pi that I got from Element 14 and all the other components I believe – except one. I am missing a way to convert the computer signals to DCC. There are products on the market to do that, such as the SPROG or more appropriately for me, the SPROG Nano, or I could even use an interface to my Digtrax Zephyr system, but that seems like cheating.

Plus, I want this to be as small and compact as possible. What I would really like is to be able to bundle everything together in a small box not much bigger than an entire normal DC or DCC powerpack. About twice to three times the size of the Raspberry Pi alone.  So maybe 3″ x 2″ x 6″ or so? Guess that wouldn’t include the power supply I am going to have to run to it. It will need power to power up the Raspberry Pi, the USB interface, and of course the actual boost of power for the trains themselves – looking to hit about 2.5 amps.

I am going to diagram this, and my proposed case, and post it soon. [ed: and here it is!]

Raspberry Pi DCC Unit

Yes, I was thinking about all this last night when I should have been sleeping.
