This new "node-sized" device consumes 1mW when transmitting and the home wiring is used as a receiving antenna. If HomePlug radiated this much, ham guys would be really happy.

UVB-76 Explained

· Score: 5, Insightful
This particular submission may be crap, but the situation around UVB-76 demonstrates that it is becoming hard to keep any secrets on the shortwave band. There are thousands of listeners at any given time. And what is much more important, they now have the ability to record big chunks of spectrum and analyze it in a way that was only available to government agencies not long ago. $500 receiver (there are even sub-$100 DIY alternatives) and free software is all you need. The next big step is exchange of such information. It may be outright illegal (UK) or borderline legal (US) to tell other what you've heard, but people do this more and more on various forums. Now including/.
Any profitable business is based on some barrier for entry for competitors. When the barrier gets lower, the profitability inevitably goes down to zero as a result of unhindered competition. This is called free market. Being angry about this is like being angry at gravity or evolution.
Censorship is never about effectively suppressing the thought or speech. It is always about politicians pretending to care about "order", "moral health of the nation" and other such big words. It earns them some reelection points (in democratic societies) or support of some part of the population (in dictatorships).
We are talking about St.Petersburg, Russia, not Florida. The average temperature is well below freezing and there is a snow on the ground (at least in the forest).
You don't need impedance transformers in this case. 75 Ohm terminators (in place of standard Ethernet 50 Ohm) will do the trick. These are much cheaper and can be hacked together at home if not found in stores. 10BaseT cards have high impedance transmitters and receivers that can drive/receive wide range of cable impedances, as long as the cable is matched at the ends (to avoid reflections).
Let the USSR demise be a warning to the US. It had nothing to do with Reagan's shaking his fists, but everything with him engaging Soviets in the unsustainable arms race. There is no real existential military threat to the US now, so having this tremendous military spending is just self-destruction for nothing.
You can get a decent P3 or Celeron laptop for under $100 (for free if you are lucky). Depending on the CPU, it can draw 15-40W under load. The upside is that usually no hardware tweaking is required at all.
I know a guy who's father was on very good terms with Bin Laden, and even supplied him with weapons and money. Oh, wait, that was _before_ he "became a terrorist"...
Progress in personal communication (I would call it "personal broadcast") is a great counterexample. Discussing your ideas with strangers all over the world in real time is a very recent concept, and it IS revolutionary.
As a kid, I could actually hear some EM quite distinctly. It was only the stronger pulse-like stuff, like arcing transformer a hundred meters away, or lightning strikes within about 2km. I can still hear lightning strikes that are fairly close as a faint crack in my head, a second or so before the thunder, but this ability seem to be diminishing as I age. Of course, there is no frickin way anybody can feel 100mW of 2.4GHz radiation from any distance, and not feel 1kW (although shielded, but leaking a lot more than 100mW) microwave oven.
If you have enough tech knowledge to set up a VoIP router yourself, you can find a provider that gives you a Canadian local phone number (in most area codes) for $2 per months plus 2 cents per minute for outgoing calls to North America (incoming calls are free). Calls to China are even cheaper:) $25/month is a horrendous rip-off for a/.-reading geek.
There is a cable reseller, CIA/3Web/Cybersurf. They offer very little customer service and as a result their "service" is cheaper than Rogers. A nice side effect is that they don't have stuff to enforce any traffic limits. And the connection is constant 8Mbit/s. Of course, Rogers can stop this at any time, because the last mile is under their control.
TFA doesn't mention it, but my guess is that the "feature" can use the CMOS sensor of the built-in camera. It is sensitive to gamma-radiation to some degree. Although this would require the camera to be always on and continuously taking pictures with the shutter closed (thus quickly draining the battery). Some new software to look for bright dots and analyze them is required as well.
Even easier than that: the rocket can be rigged to switch from the sensitive guidance system looking at the engine heat to a really dumb one looking at the bright laser. This "countermeasure" is not more intelligent than attaching lasers and wings to sharks and releasing them from the plane when a rocket is approaching.
I wonder how they counted VoIP services. As a landline? The share of VoIP is substantial in Ontario, to the point where Bell Canada has to run landline commercials and is offering their own VoIP "home phone".
Defensive patents are not used to protect the patented idea. They are usually used as a weapon when the company is sued by a competitor for something completely different. This tactics doesn't work against patent trolls, but works very well against competitors. No computer company can touch IBM because of fear of their patents. I think Google is trying to achieve the same status.
Rogers in Canada behaved in a similar way. They sent threats of disconnect for "excessive use" without telling the limit and even without telling people how much they downloaded. First type of complaints people submitted to Competition Bureau (SEC in the US?), about Rogers using their monopoly position in areas where no competition was available to increase profitability at the expense of customers who had no alternative. Second type of complaints was to Privacy Commissioner, concerning the personal information collected by Rogers (traffic use). According to Canadian privacy laws, this information must be given to the customer upon request. This pressure actually worked, Rogers later implemented usage counter and then declared the usage limit in GBs (60 or 100, don't remember).

(For "node-sized," think "size of a breakfast cereal prize.")
Don't know about yours, my node is way bigger than this.

Now imagine what may happen when schools turn them on.
I wonder how many of the "concerned parents" switched back to wired networking at home.

Doing math is fine, but picking mushrooms in St.Petersburg in March is kinda borderline.

Maybe the Streisand effect was the desired outcome in this case. For many celebs, there is no such thing as bad publicity. Any publicity is good.

That would be nice, but you don't "simply" flip the hourglass. You expend energy while lifting the sand from lower to higher position.
