I just went thru’ this process to wipe a stack of drives before I dropped them off at the local Goodwill Computerworks…
With stories abounding of identity theft aided by information lifted from discarded storage devices, you want devices you no longer plan to use to have no usable information when they head out the door. Here’s how to wipe them clean.
This is good stuff when choosing colors for designs…
Color in design is very subjective. What evokes one reaction in one person may evoke a very different reaction in somone else. Sometimes this is due to personal preference, and other times due to cultural background. Color theory is a science in itself. Studying how colors affect different people, either individually or as a group, is something some people build their careers on. And there’s a lot to it. Something as simple as changing the exact hue or saturation of a color can evoke a completely different feeling. Cultural differences mean that something that’s happy and uplifting in one country can be depressing in another.
Someday, when I run out of projects… maybe I’ll build one of these… 🙂
After visiting some web pages about 2.4 GHz ISM band spectrum analyzers based on the CYWM6935 module, I tried to build my own analyzer, but with some improvements. The references I found on the net used the parallel port or a serial link to a host computer. I want the analyzer to be portable, and easy to transport, so I will use a microcontroller and a graphical LCD.
This has gotten me so freaked out that I have this new habit where I inspect an ATM carefully even before I take my wallet out… yikes!
Easily the most-viewed post at krebsonsecurity.com so far has been the entry on a cleverly disguised ATM skimmer found attached to a Citibank ATM in California in late December. Last week, I had a chance to chat with Rick Doten, chief scientist at Lockheed Martin’s Center for Cyber Security Innovation. Doten has built an impressive slide deck on ATM fraud attacks, and pictured below are some of the more interesting images he uses in his presentations.
According to Doten, the U.S. Secret Service estimates that annual losses from ATM fraud totaled about $1 billion in 2008, or about $350,000 each day. Card skimming, where the fraudster affixes a bogus card reader on top of the real reader, accounts for more than 80 percent of ATM fraud, Doten said.
Sadly, I agree… except, the last line in his article… I think TED is done too. 🙁
The Interactive portion of the conference drew over 12,000 attendees this year, and the rumor going round is this is the first year that Interactive has more badge-holders than Music. But the same rumor went around last year, and who cares, Music’s still got all the wrist-banders too. Burning Man gets bigger every year, but it’s (reportedly) pretty much as cool as ever. What’s different at this year’s SXSWi?
I was fascinated with this antenna design when I saw it at a local ham radio meeting… I love how you can roll it up for travel…
This antenna evolved during my search for a beam with a really great front-to-back ratio to use in hidden transmitter hunts. This design exhibits a very clean pattern and is perfect for RDF use. It trades a bit of forward gain in exchange for a very deep notch in the pattern toward the rear. (You could optimize the design for more forward gain, but at the expense of a really good notch in the pattern toward the rear.) It is a design that can be constructed using only simple hand tools (no machine shop needed) and still perform well. It has been duplicated several dozen times by other local hams and has been successfully used as a club construction project.
