All the locks featured seem to be something I'd only use for cellar that stores old mattresses or similar, but not for anything valuable (like my home). Is there any information whether this bumping works against real locks such as ABLOY?
The question should be why can't he get a good 5:1 speaker system for less then the cost of 400 gig hard drive? You have just told him to spend as much on the audio as on the rest of his entire system.
Because audio reproduction is still governed by the same laws of physics as it was 30 years ago. Bass response is dictated by the size of the transducer and the cabinet, and while you can do minor tuning with active EQ, you simply cannot compensate for 50 times too small enclosure. The enclosure must also be rigid and without obvious resonances, hence you need either thick walls (of MDF or similar material) or fancy and expensive manufacturing (as in Genelec's new 8000 series monitors).
Can't stand US born and raised teens at the checkout line that can't understand or respond to a simple question.
Add to that list the huge number of slashdot users who can't separate than/then and other similar words. Very annoying to read for a non-native speaker.
English is the de-facto standard language of the internet and technology. An ISP without english speaking employees has no business connecting to the internet. It's not like learning passable english is hard. I should know, I did it by the time I was 12 (as did the vast majority of all the other students).
My personal favorite is definitely the Vff rating (6.3V AC). For those (sane) individuals who don't build their own amplifiers, this is the voltage used in electronic tubes for the heater filaments. Come to think of it, this would also explain the need for a 6 inch cooling fan.
The legal system can't stop me from wandering down to radioshack and picking up a 1M resistor and a 741 opamp.... Christ, their security scheme could be bypassed for $2.50 in parts!!!!
Perhaps, but if you want any quality at all a 741 op-amp is a braindead idea. It was pretty good back in the seventies (actually it wasn't good, it just was the only decent op-amp back then) but nowadays there are MANY better options (like the cheap and good TL072).
The radio signals induce currents in the wires inside your TV/radio/whatever. The currents are rectified by any active semiconductor (transistor, ic, whatever) and the resulting signal has frequencies all over the spectrum. So your nice 900MHz GSM signal gets transferred to audio spectrum. This "artifact" is used in primitve AM receivers to convert the filtered (just the channel you're listening to) high frequency signal to an audio frequency signal.
The reason older analog cellular phones don't do this is that they send a continuous but relatively low power signal. Digital phones send bursts of high power signal so audio electronics picks it up a lot easier. The average power over time is about same for analog and digital phones tho.
Bizarreness. I spent about two hours the other night studying using the mic port.
You could build a random noise generator easily and cheap. Here's an example circuit. The idea is to amplify the natural noise of a transistor (white noise) and then hook that to soundcard. Cost is < $10 + the price of wallwart.
You really should see our #5 demo from Assembly '96. It might work in win95 dos shell or it might not. It might work with emm386 or it might not. 8 bit graphics modes WON'T work.

That is perfectly true *IF* you believe that a slave is in fact property. Slavery was abolished with the shift in paradigm: that people cannot be owned (i.e. they cannot be property).
Replace slavery and people with information and see how your statement turns out.
That's almost like plugging in an ISA card while the computer is compiling a kernel.
Actually that would be perfectly safe if you could guarantee that all io pins were in low state.
The danger with hotplugging is connecting an io-pin in high state before Vcc. This results in input protection diodes being turned on, effectively short-circuiting Vcc and ground.
Correct if I'm wrong (really), but where _could_ you put the descrambler where at some point it would not be possible to grab a digital copy of the data.
In the video DAC. Encrypted data goes in, unencrypted analog signal comes out.
European AC mains is always 50Hz afaik. It may vary between 220 and 240 volts, but that doesn't matter as all power supplies are designed to accommodate for small variations (10% or so).

Microwave oven does not produce alpha/beta/gamma radiation. It produces high frequency radiowaves that heat water molecules in the food.

It could be the electrolytic capacitors blowing up. If you connect one to wrong polarity, it WILL blow up. And produce toxic gases so I don't recommend experimenting indoors.

This just changes where the A/D conversion happens. Instead of happening inside the computer it happens inside the speaker cabinet.
People seem to forget that the only way to distinguish the codecs is with very good equipment. Consumer class soundcards certainly don't fall into that category. So as long as you don't burn the mp3's (or whatever) to CD and listen with a Good player it doesn't really matter.

Abloy is used in practically every single door with a lock here in Finland. Most serious padlocks are Abloy too.

I suggest you check out some of the 4k intros on
ftp.scene.org. They've got 3d AND sound too. In 4096 bytes.

P.S. Compare the sound quality side by side, and
hear the difference for yourself -- I did!
I think I'll stick with my Denon CD player & amp and B&W speakers. I doubt they sell as good digital speakers yet.
