Wireshark 1.2.0 - New Version

Wireshark is a tool that performs packet and protocol analysis on a network. Packets are the virtual transport mechanism that moves are data from sender to receiver. Each packet has a header and payload - the header contains information about where the packet came from and where it's going, as well as the protocols being used. The payload has our actual digitized data - parts of website, text, a section of photo, or a clip of audio from an MP3 or a phone call. If you don't get all of the packets then a phone call may sound choppy or it may take a while to download a complete file. Wireshark allows you to take a look at the packets you are sending and receiving and learn a lot more about what it happening and what's breaking down. Wireshark is not for the lighthearted, as the tool requires knowledge of protocols and a deep understanding of OSI, IP, and TCP/UDP at the very least. But, with time, Wireshark becomes invaluable to the troubleshooting process. I have relied on the tool for my work supporting Voice-over-IP (VoIP) and system and application connectivity. The only side-effect to Wireshark is that you will soon realize why it's not a good idea to surf the web in a public spot (without a VPN or encryption).

The new version of Wireshark includes more protocols that it will decode, supports 64-bit Windows, and has GeoIP integrated support. Also, Wireshark works perfectly with my passive network cable. Visit www.wireshark.org to download the latest version and learn more about it.

Clearblue Screen of Death

Everything is going digital. I know, a profound statement, but the consequences of "digital" are a future riddled with software bugs, failures, and EMP induced outages (the EPT EMP to be exact). We rely on technology to get us through our days and we will be faced with crashes when we need technology the most.

"Clearblue" has released a digital version of their pregnancy tester. My girlfriend, completely fictional to make a point, and I were discussing the ramifications of a digital pregnancy test. One day the test will be dependent on an Operating System to drive the user interface. It might even have Windows on it.

In your critical moment, of whether you will be with child or have more time to yourself -- unshackled by a disappointing version of yourself, the pregnancy tester will crash giving you an ambiguous result.

Take a glimpse of the future. You have been warned.
