Comment: Using NetStumber to measure microwave oven leaks (Score 1) 124

by Mozz Alimoz (#37505378) Attached to: Wi-Fi Cards Can Now Detect Microwave Ovens

I had a microwave oven that consistently stopped my Netflix videos streaming over WiFi every time someone made a cup of tea.
I was able to prove a contributing issue was related to its poor door seal letting microwaves out using the free WiFi tool NetStumbler (Also known as "Network Stumbler").

NetStumbler has can graph the Signal/Noise ratio of a WiFi station over time. If you put a laptop running NetStumber in a microwave (Don't turn on the microwave!) you should see the signal to noise ratio drop 30 dBm as the door shielding attenuates the WiFi signal. If not, you probably have an old oven that has developed a wonky door seal.

In my case, I was able to feel the microwave door close a little more as I pressed the handle. And after alternating pressing and releasing the door without changing my body position, 10 seconds on 10 seconds off, I was able to clearly see a 5 dBm difference in the WiFi signal to noise ratio on my old oven. That didn't happen on my new oven.

I also saw other people comment that if a cell phone rings inside a microwave, then that's a sign the microwave is leaky. I doubt that's reliable, since many cell phones use a different frequency than microwave ovens. And they don't report signal strength accurately.

EA Shuts Down Pandemic Studios, Cuts 200 Jobs 161

lbalbalba writes "Electronic Arts is shutting down its Westwood-based game developer Pandemic Studios just two years after acquiring it, putting nearly 200 people out of work. 'The struggling video game publisher informed employees Tuesday morning that it was closing the studio as part of a recently announced plan to eliminate 1,500 jobs, or 16% of its global workforce. Pandemic has about 220 employees, but an EA spokesman said that a core team, estimated by two people close to the studio to be about 25, will be integrated into the publisher's other Los Angeles studio, in Playa Vista.' An ex-developer for Pandemic attributed the studio's struggles to poor decisions from the management."
