Comment: Defense in depth, physical security first always (Score 1) 508

You need to adopt a defense in depth approach similar to computer security.
First you need to block all breakins through windows. install aluminum shutters on all your windows from the inside with remote motors. These run about $200 including labor for a window, manufactured in germany and installed locally.
Then replace your doors with steel commercial fire rated doors. these are over an inch thick and put digital locks on the doors, preferably Kaba Mas which are DoD compliant. The doors run around $1000 including labor.
Thirdly put IP cameras with built in recording. DVRs are too easy to steal. Use Trendnet IP522Ps with built in SD cards. You can also use axis. Make sure you cover all approaches and remove any trees shrubs etc.
Make sure you have 6 ft high fences around your property or whatever the highest available fence height is from your local minicipal regs. behind the fence create a 4 ft buffer zone and plant cacti such as ocotillo. This will deter fence jumpers.
Finally put a vista 20P alarm system you can get cheaply off ebay for $250 or so with panel alarm and sensors. The motion detectors are $10 - $20, the glass break sensors are cheap and door sensors are like $5. Install a GSM board and find a cheap local security company to monitor it.

For all the non lawyers at /. this may seem a travesty but this is such a brilliant piece of legal work by the prosecutor. Not only has he become famous -- instantly, he has a shot at changing the way the country functions and has managed to get untouchable people to be touched. Plus he has managed to get attention from the international community and the heads of his state. I expect that he has a good shot at putting the scientists behind bars after which he will move on to a well deserved legal career as a lawmaker. Expect solid career advancement as he might end up in the Italian cabinet one day.
Consider the response of all the international media AND the scientist organizations -- Scientists prosecuted for failed earthquake predictions. OMG !
Consider what is actually in the prosecutors complaint -- Scientists failed to communicate risks clearly as per their legal duties, which were attached to them as a result of their jobs.
A truly brilliant prosecution. With a good shot at changing the planet in a small way. With a tiny lever, great changes can be achieved.

the toshiba 4S is a sodium metal reactor. take that and shove it 30m underground to produce 10MW of power. awesome.
until you factor in the earthquake and tsunami.
water + sodium = BIG BOOM.
and the fact that regulatory approvals take a shitload of time for EACH reactor.
and you need 1200 of them to even come close to meeting demand.
and 1200 x 100s of days of regulatory paperwork is much more than 2-4 conventional plants with 100s of days of paperwork each.
not to mention environmental impact assessments at EACH SITE for EACH of those 1200 reactors.

the toshiba design needs to use lead and be rebuilt. the legal process needs to change which will take longer than it takes to build conventional plants. in short... NO.

its not like the ISS is doing anything critical or military related. the military stuff will still launch on delta iv heavy boosters off vandy or the cape.
the ISS can also sit there parked in orbit for years with no one on board. its not like its going to fall down cuz joe blow astronaut was not up there to go out and shove it back up the gravity well or something. hell there were plans to shut the whole stupid lame ass project down anyway. its a white elephant. no commercial value, minimal scientific value compared to robotic probes and basically worthless for long term space exploration due to its placement in low earth orbit.
now build a tanking platform with robotic spacecraft construction/assembly/food production/power generation/roid mining gear at lagrange points l1/l2 for staging earth/moon/mars/europa missions and that makes much more sense.

I have the same problem. I am not in a restrictive country, however my phone lines are tapped on a regular basis since i deal with defendants. its not paranoia -- they really do tap phones of attorneys to get around atty/client and ive seen the records more than once. I use an SSH connection to a tomatousb router (ASUS RT-N16) and forward ports to my N810. you can do the same with your N900. this allows me to do VOIP directly and also share the same connection locally by letting my N810 serve as a local hotspot. All traffic is encrypted with SSH until it reaches my home which is on a dynamic ip anyway. This has worked against local and fed agencies but may not work against NSA/big brother type agencies or against foreign government state departments. You need a fast upload connection (my 25/2 Mbps cable connection works fine). For anything more than the usual calls i meet people in person at the office. meeting in person is covered by priv and works well.

How this actually works :
The Challenge in Achieving Full-Duplex

The problem that has historically prevented full-duplex is that, when a node transmits, its own signal is millions of times stronger than other signals it might hear: the node is trying to hear a whisper while shouting. The challenge is canceling the node's own transmitted signal (shout) from what it receives (whisper). Existing approaches, such as digital cancellation and noise cancellation circtuis, can cancel some of the transmitted signal, reducing its strength, but not enough to make a node able to receive.

Antenna Cancellation

Our design uses two transmit antennas one receive antenna per node. The transmit antennas send the same data and the receive antenna is placed such that there is destructive interference from the two transmit antennas, thus reducing self-interference. Offsetting the two transmit signals by half of the wavelength causes them to cancel each other, creating a null position where the transmitted signal is much, much weaker.

Combining antenna cancellation with cancellation through a noise cancellation circuit gives ~50dB reduction in self-interference before the RF signal is demodulated and sampled to the digital domain. Digital cancellation removes the residual interference.

also is there any good mapping of what an individual worm neuron does ? how does it use chemical and electrical functions to execute commands.

the difference is basic stupidity. It was PHB stupidity which made the SCADA systems run windows - an operating system so unreliable the majority of servers are running a homegrown unix (linux) to ensure stability. If you insist on building your industrial infrastructure out of paper and cardboard, you should assume the first hurricane to come along will blow over your origami construction. A decent airgapped SCADA system running on any decent unix (heck just use a bunch of sun enterprise boxes on solaris to run it) would never be vulnerable to this sort of an attack. Build your industrial infrastructure on industrial equipment or face the consequences. since when is windows certified for running anything much less nuclear plants ???

Without ideology we wouldn't have the scientific method.

I find it strange that people think the scientific method is based on a philosophy or ideology. What scientists do is no different from what us common folk do when we debug a program or try to fix a mechanical system: you notice something funny (program gives wrong result, car won't start, water rising in basement) so you or the called-in expert speculates on the cause and then proceed on the basis of that speculation. If the facts don't bear it out, you pause, scratch your head and come up with a new speculation. Repeat as needed.

AFAICT even the most uneducated of us operate the same way in whatever we do. I suspect it's instinct, or at least such a basic result of the exercise of intelligence that no intelligent species could avoid operating that way.

thats interesting. where do you suppose the speculation come from ? only prior experience/learning ? or somewhere else ?

Submitted by sciencehabit
sciencehabit (1205606) writes "You may not give a lot of thought to what happens inside the battery of your laptop or cell phone, but to judge from this video, it's not a dull place. The battery in question is a miniature rechargeable lithium-ion device, and the clip shows what happens when it is charged. As lithium ions flow from the positively charged cathode into the 200-nanometre diameter wires of tin oxide that make up the negatively charged anode, the nanowires writhe and bulge, causing them to expand up to 2.5 fold. The wires also change structure from a neatly ordered crystal to a disordered glassy material. These distortions may explain why such batteries ultimately wear down. Knowing more about the process may help researchers develop longer lasting, and perhaps much smaller, batteries in the future."

Shiwei (666) writes "While BitTorrent is the most popular P2P protocol, it still relies on several centralized points for users to find the files they are looking. There have been several attempts at making BitTorrent more decentralized, and the latest Tribler 5.3 client is the first to offer the BitTorrent experience without requiring central trackers or search engines. Tribler offers some very interesting technologies; the latest version enables users to search and download files from inside the client. Plenty of other clients offer search features, including the ever-popular Torrent, but Tribler's results come from other peers rather than from a dedicated search engine. Users can search and download content without a server ever getting involved; everything is done among peers, without the need of a BitTorrent tracker or search indexer."
