  4. Off the pig! Time to get rid of OSs on VMs. on New Operating System Seeks To Replace Linux In the Cloud · · Score: 5, Insightful

    This is a language-support library. It replaces the C runtime system, and the bottom levels of the Java runtime system. For environments where a virtual machine is running one program, or a family of tightly related programs, that's all you really need. The real operating system is the hypervisor underneath and the remote management tools that run the cluster.

    Linux, with millions of lines of code, just isn't doing much inside a VM. It's not managing the memory. It's not handling real devices. It's not handling real interrupts. It may not even be managing any file systems - in cloud environments, those are usually out on some storage area network. It's just a big fat pig of an OS that needs to be fed patches and attention to keep it going, while not doing any useful work.

    Within the virtual machine, there are no security boundaries. This may be a problem if more than one application is running in the VM. But if you only have one big program with many threads running, the OS isn't doing anything for you in security anyway.

    The ship is now upright. It's not floating; it's sitting on the underwater platform built for it, sunk several decks deep, and still full of water. Next step is to patch the hole in the hull, get pontoons on both sides, and start pumping. Big job, but now a routine one for a salvage company.

  7. Overly complex, but working on Cruise Ship "Costa Concordia" Salvage Attempt To Go Ahead · · Score: 2

    Doing that in a marine sanctuary would have a significant environmental impact.

    That's part of it. The other part is that the ship is on the edge of a slope into deeper water. There was real worry that she'd slide down the slope while passengers were still being evacuated. After that, the big worry was that she'd slide down the slope, break up, and leak bunker oil for years, producing a long-term oil spill. The first phase of salvage (by Smit, the Dutch salvage firm) was to drain the fuel tanks and stabilize the hulk. They did that with few problems.

    Then it got political. If Smit had been given the contract to finish the job and get rid of the hulk, it would have been cut up and out of there by now. That was their proposal. But there would have been some medium-term damage to the environment in the area.

    Hence the rather elaborate plan currently underway. The ship isn't just being pulled upright. That's not enough; it's full of water and wouldn't float. An underwater platform was built to support it, and it's being pulled onto that. Then it gets re-floated and towed away.

    This is probably the most elaborate (in the overkill sense) marine salvage operation since the Army Corps of Engineers removed the wreck of the U.S.S. Maine in Havana harbor in 1911. They built an enormous temporary dam around the entire area. Then they pumped out the entire area around the ship. Then they cut up the wreckage and hauled it out. Then they let the water back in and dismantled the dam.

    DBI has built control rooms for other agencies. Here's their portfolio. They did the new White House Situation Room (which looks reasonable), the National Counterterrorism Center (overdid the lighting effects), Lockheed Martin (looks like a movie set, overhead lighting grids and all), a NASA auditorium (just rows of seats and some big screens), GeoEye (overdid the ceiling design), Defense Information Security Agency (fancy ceiling, lots of Eames chairs.)

    But only for the NSA facility did they really go over the top. This is the silliest control center design since the Moscow United electric power control center The layout makes no sense. The person in the "Captain's chair" is in front, and can't see what everybody else is doing. The "captains chair" has no controls or screens of its own, so whomever sits there cannot do anything except shout orders.

    A common setup in operational control centers, especially USAF and NASA, is to have the ability for each station to look at screens of other stations in view-only mode. (Originally this was done with an actual channel selector and an analog cable TV system). When something important is happening, a lot of people may need to look at one display. This eliminates everybody crowding around the station that has the key information at the moment. Once you have that, the physical layout doesn't matter as much.

    The result is that most modern military command centers are rather boring - they look like a help-desk operation. The current NORAD center looks much less impressive than its predecessors. In the field, a bunch of laptops in a tent can operate as a command center. A modern tactical operations center looks like that, not like one of these fancy overdecorated rooms.

    I own a domain in .com for which a private school in the UK has the same domain in the .co.uk namespace. I used to have a catchall email address for that domain, before spam made that useless. So I would occasionally get misaddressed mail for students at that school, all of whom had addresses within the school domain.

    So one day I get an email: "I am going to kill you tonight". It's not addressed to me, but to a student at the school. This was shortly after Columbine, so I thought I should do something. I was able to reach the headmistress of the school by phone. They had to wake her up for this; it's the middle of the night in the UK. I read her the email.

    "The problem with Google's current approach is that the sensor system is too expensive" - Musk

    He's referring to the expensive Velodyne rotating array of 64 LIDARs found on top of Google's cars. It's a useful device, but it's a research tool, not something that belongs on top of production vehicles.

    What's needed is a compact solid-state 3D LIDAR for outdoor use. Advanced Scientific Concepts makes such things, but they're sold to DoD for about $100K each. Typical performance is 300 meter range, 128x128 pixels, 30 FPS. There's no fundamental reason the technology needs to be that expensive; it's just that the things are hand-made at a lab in Santa Barbara, CA. (I visited them a decade ago when we were doing a DARPA Grand Challenge vehicle. Back then, they had the technology working on an optical bench, but didn't have usable hardware yet.) This technology needs to be turned into a mass market product. The current generation Kinect, (which is a true LIDAR, not a trianguation sensor like the previous model) does roughly the same thing, but with a less sensitive sensor and a weaker laser. Eventually somebody will put enough money behind this to get it right.

    That's a good point. While the US and the UK have had a formal agreement on intelligence sharing since WWII (the UKUSA agreement), they're allies of the US, with a mutual defense treaty (under NATO) with the US.

    Israel is not formally an ally of the US. While the US provides "security assistance" to Israel, there's no mutual defense treaty. There was an "exchange of diplomatic notes on mutual defense assistance" in 1952, and there's the Camp David agreement (US, Egypt, Israel) from 1979 which ended the wars between Israel and Egypt. Other assistance from the US is on an ad-hoc basis, and it's mostly money, not troops.

    This is significant. When some parties in Israel were talking about bombing Iran, and expecting the US to help, the chairman of the US Joint Chiefs of Staff told Israel that the US would not become involved. Not Congress, not the President, the head of the JCS. No treaty, no support without orders from higher.

  21. Over the limit on microwave exposure on Wireless Charging Start-Up Claims 30-Foot Radius · · Score: 1

    OK, let's take a closer look.

    The issued patent from the application linked above is US 8,446,248. The claims are quite narrow, because, over five years of rejections and reexaminations, the USPTO examiners found prior art and narrowed the patent coverage.

    Back in 2003, Geoffery Landis at NASA (also a visiting professor of aeronautics at MIT and an SF writer with a Hugo) proposed something similar, and that was patented. The NASA patent says "The present inventive technique provides for wireless, charging power and/or primary power to electronic/electrical devices whereby microwave energy is employed. The microwave energy is focused by one or more adaptively-phased microwave array emitters in a power transmitter portion of the system onto a device to be charged. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power. A locator signal generated by the device to be charged is analyzed by the system to determine the location of the device to be charged relative to the microwave array emitters, permitting the microwave energy to be directly specifically towards the device to be charged.". That's the basic idea here.

    The Landis patent gives a much clearer idea of the concept. It's simply a steerable microwave beam aimed at the receiver. That's known to transmit power just fine. You could do that with a mechanically steered dish. There are some tricks; one is noticing backscatter from the beam, indicating that it's hitting something that isn't a receiver, so stop aiming there. Another is finding the receiver with low power, then upping the power once on target. Much of this is borrowed from the solar power satellite scheme of the 1980s, with ground based "rectennas", which is why this came out of NASA.

    There's a safety issue. The US safety standard for microwave exposure is 10 mW/cm^2 for periods of 0.1-hour or more. To get 1 watt at the receiver, it's going to take maybe 10 watts of output at the transmitter. If the emitting area is about two square meters, as in his demo, the energy is spread out over 20,000 cm^2, so there's only about 0.5mW/cm^2 in front of the transmitter array. That's OK.

    At the receiver end, all that power is supposed to be focused to a point, or at least down to the size of his little box. That should focus at least 1 or 2 watts onto his little box, with maybe 25cm^2 area. Now we're up to 40 to 80 mW/cm^2, which is well above the safe limit for prolonged exposure. Since you may be wearing or carrying that little box, and it's going to take a while to charge the battery, this isn't too good.

    It's a nice demo, but a system which focuses microwave power beams on handheld devices probably isn't going to be acceptable. What it looks like he did here was to gang together a lot of off the shelf devices which individually can't emit enough power to be dangerous, but when combined into a phased array put too much power in one place.

    If it is now merely feeding the pool as one of multiple sources, then it's OK. If anything is directly exposed to raw rdrand output, something is very wrong.

    That's exactly right. Even if the hardware RdRand has a "work reduction factor" built in, i.e. it's not as random as it seems to be, there's some randomness there, and it can be fed into the entropy pool along with other sources of randomness.

    Randomness sources inside deterministic computers are scarce. Disk timing, clock jitter, network arrival times, etc. are useful, but generate random bits at a low rate. Thus, "/dev/random" will block if not enough random bits are currently available. This usually isn't a problem, but if every TCP connection you open is SSL and you need random bits for key generation, the supply could run out. If, say, you wanted to fill a DVD with random bits for a one-time key system, /dev/random would probably be a bottleneck. Is Torvalds making that argument?

    There's another application of randomness. The only known theoretically unbreakable cryptosystem is a one-time key system where 1) the keys are truly random and 2) are used only once, 3) then destroyed. One time key systems have been broken in practice due to violations of each of those rules. Venona violated rule 1 and 2, and there have been spy cases where the spy hadn't destroyed their keying material when captured.

    A reasonable cryptosystem is to make two identical DVDs of random bits. Each party has a DVD, and they can communicate as many bits as they have random bits in common. This is a pain, but it works. Such systems are used by the US for embassy-to-capital links. In the paper-tape era, this was a huge pain, but a DVD can store enough data for a thousand hours of phone calls.

    Any reduction in randomness in a one-time key system makes it very vulnerable. It doesn't take much to provide an entry into the cypher.
