SSL may not be good enough...
Some interesting findings were presented at this year's Black Hat conference. See this AP story to read more. This conference take-away recap is also interesting.
How to install the Ruby gem command
I hunted around for this for a surprising time and decided to post it here, because I couldn't find one place that said, "This is how you do it!"
To install the Ruby gem command on your Linux system:
1. For Ruby 1.8.5 or less, download rubygems-1.3.5.tgz:
pushd ~/Downloads
wget http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz
2. Unpack it in /var/tmp:
pushd /var/tmp
tar -zxf ~/Downloads/rubygems-1.3.5.tgz
3. Run setup.rb as root:
pushd /var/tmp/rubygems-1.3.5
sudo ruby setup.rb --no-ri --no-rdoc
That will do it! Now you can use gem to get lots of other useful Ruby packages :-)

My eReader Choice
I'd been watching the eReader market for a while with interest. At first, it was only Amazon and Sony, then Barnes & Noble jumped in. I didn't like the complexity of the Kindle, although I had to admit it has awesomely crisp and readable print.The Sony units would handle PDF documents, but they were pricey and were too bulky for my backpack.
One day, I visited a B&N store and handled a Nook live. I was surprised at how thick and heavy it felt. Silly me, I was also expecting a full color display, not realizing that only the small navigation LCD can do color. I liked the combination of features, but Nook and the other candidates were pretty pricey for me. So I passed on it and decided to wait a while longer.
Then, a month ago, I found out that Borders was jumping in to the fray with the Kobo eReader. I was immediately intrigued by the Kobo, as it seemed to offer simplicity, a comfortable feel, and was thin and light as well. Although it lacked wireless connectivity, I didn't care, because I usually have a laptop handy anyway. And the price (at that time) was half the cost of the others! So, I visited my local Borders store and ordered one; and it arrived at my door within ten days. Now, I'm happily eReading books and PDF docs that I wouldn't have been able to truck around in my backpack otherwise! SWEET :-)
