QPSK [Quadrature Phase-Shift Keying] is a system of modulating digital signals onto a radio-frequency carrier signal using four phase states to code two digital bits.

Well it looks as if Chris is really enjoying his vacation to Alaska thanks to Holland America cruises. Being as I am from Alaska myself, I had to admit that I was somewhat envious of Chris being able to take this trip up north and away from the “Lower 48.”

How do you truly know when email has become a problem without a good solution? Simple. Take a vacation. This is a clue…

The market for Wireless LAN Intrusion Prevention Systems (IPSs) will double in size in 2006 as more organizations look to tighten the security of their wireless networks. To help organizations address their WLAN IPS needs, Gartner has assessed seven vendors that offer overlay WLAN IPSs or have integrated WLAN IPSs into their WLAN infrastructure components.

For small and large database projects, Microsoft Access works wonderfully. If you have a database with hundreds of thousands of records, maybe even connecting to other databases remotely, Access will work just fine. Security isn’t too much of a problem (no Access database is truly secure), and with a wide range of options for publishing […]

In the animated tutorial there is a brief comparison between Zigbee, Wi-Fi, and Bluetooth, which all operate in unlicensed 2.4 GHz and other frequencies. Zigbee is an IEEE 802.15.4 standard. Zigbee is designed around low-power consumption allowing batteries to essentially last forever. Key features are:

Data rates […]

I can hardly believe that this has happened - the Outlook compatible PIM for Linux known as Evolution is now available on Windows. As a matter of fact, I actually emailed Pirillo about this the moment I first discovered the application had finally been successfully ported.
It’s great on Linux, but on Windows - there are […]

Known for their ruthless efficiency and almost fanatical devotion to their language of choice, Python programmers seem to have it all: a language that’s elegant and pragmatic, simple and powerful, and is high-level yet doesn’t intrude between programmer and code when one needs to fiddle with the bits and bytes. Furthermore, Python is relatively easy […]

Today, every enterprise must put the reins on spending in every location and category. This white paper, Managing Services Spend, highlights how some companies are using world class applications to manage services spend.

Frequency Converters are used to convert 2.4 GHz input channels to 5.7 GHz output signals to expand service or provide service where there is congestion. The 5.7 GHz is another low-power unlicensed FCC set of frequencies. However, there are now cordless telephones, wireless stereo amplifiers, CCTV [Closed […]

To increase the reliability of security testing results, developers are finding that security testing should be a combination of analysis techniques - utilizing source code analysis information to direct a second, more practical approach called dynamic analysis. This enables developers to identify vulnerabilities more accurately and confidently than with either technique individually. This combination approach, […]

Routing protocols provide routers with maps and directions to route TCP/IP [Transmission Control Protocol/Internet Protocol] packets. Routing protocols route messages between routers, not users. That is, routing protocols do not carry or transmit data (email) or content. RIP [Routing Information Protocol] is a routing protocol that […]

Ubuntu Linux for Non-Geeks was written by Rickford Grant, a teacher/author who has made his name explaining tech concepts to novices in previous works such as Linux For Non-Geeks and Linux Made Easy (both No Starch Press). He has a natural talent for anticipating when and how a newbie will goof up. If you don’t […]
