The iPad Hype: Much Ado About Nothing?
Apple Computers (yes, that is what it originally was) recently announced a new iPhone-like mobile computing device called the iPad. Unless you live in the most remote of Islands, I'm sure that is all you've heard or read about in the past week. (more...)

Software Vendors Encourage Security Lapses
I am now convinced that computer software vendors, knowingly or otherwise, help perpetuate insecure computer practices. They do this by the ridiculous practice of pushing out updates through executable files which ninety-eight percent of the time will get blocked by the security software we encourage users to install on their systems. You get a notification that an update is available, and you cli...

I know where you are!: Mobile devices and GPS

Posted By: Daniel on May 20, 2009 in Cloud Computing, Ethics, Web Technology, Wireless Technology - Comments: No Comments »

The other day I was in Houston for a seminar and as usual, got lost, despite the fact that I had a printed map and directions to the venue. I called the hotel I was going to stay at for help and they hung up on me. Oh well. After taking a few more wrong turns, I suddenly remembered that my G1 has a built-in GPS. I pulled over and opened the “Maps” application hoping to use it get new directions. The menu had an entry called “My Location” so I tapped on it and lo and behold, it brought up a street map of my exact location.

Roll Your Own Captive Portal

Posted By: Daniel on March 26, 2009 in Linux, Open Source, Security, Wireless Technology - Comments: 2 Comments »

A lot of businesses these days, especially small cafes, coffeee shops and restaurants, offer free WIFI services to their customers. The problem is, many of these wireless devices are left wide open and unsecured because customers and business owners do not want to deal with the hassle of locked down services. An alternative is to sign up for expensive “portal” services that  creates a “landing page” for the customer where they can sign up for the use of wireless services. But what if you can create your own so-called captive portal and hand out one-time use login credentials to customers who actually spend money in your business environment? Let’s say you own a coffee shop, and you see a customer lugging a laptop when they walk up to order coffee. You can hand them a piece of paper with a login username and password that is good for two hours of free browsing. After the two hours, they can pack up and leave, or order another cup off coffee.

The good folks from the Open Source community have several tools available that you can use in building your own customized captive portal with your logo, business information and a little word of encouragement for your customers. One such tool is the FreeBSD based pfSense. It runs as a LiveCD and can be installed on an old Pentium II computer with as little as 1GB hard drive and 128MB of RAM.
