  1. Re:XFoil on Finding Airfoil Data For Amateur Projects? · · Score: 1

    Strictly speaking, XFoil is not under GPL. The webpage lists additional requirements, such as the requirement to open code to any port of the software, regardless of whether the modified code is distributed. Also, the users are required to accept those conditions in order to be allowed to download the software. Doesn't look like GPL to me, even it says GPL.

    "Proper space crafts" will take at least twice the amount of fuel. A rocket that puts 25 tons to LEO puts 10 tons to GEO. If you go above that, you need more fuel. If you change inclination, you need much more fuel. More fuel means bigger rocket, higher price.

    Ion engines should work for months to be effective. Ion engines mean more food and other stuff for the crew, and that again translates to a bigger rocket.

    Either we build the space elevator, or we start mining the Moon or we make smart robots and send them to do work for us. Otherwise is will be another money sink with low return on investment. We cannot bring everything from Earth with us.

    Maybe we should develop universal space robots that could fix satellites? Using an ion engine and solar arrays, such robot could to change orbit gradually to approach any satellite. The robots could dock with the ISS for service and to refill engines. Even if it takes months to change the orbit, it would still save a lot of satellites. We probably don't have the techology to make truly universal robots with abilities close to those of astronauts, but it shouldn't be take very long to develop such systems given sufficient financing. And that's the case where the advances in technology would certainly return back to Earth.

    On the other hand:
    • It's easier to launch stuff from the Moon because of lower gravity and missing air drag.
    • It's easier to send stuff from the moon to the Earth orbit than from Earth itself, let alnone Mars!
    • There is more sunlight on the Moon, hence more solar energy.
    • There is more aluminum on the Moon. Iron is harder to extract if you don't have coal.
    • The Moon is one light second away. It's possible to control robots remotely and get feedback almost in real time.
    • Communications are easier. In particular, the Moon aligns with Sun for days, not for months.
    • There is no bad weather on the Moon. Ever.
    • It's likely that water and other solvents are deposited in craters on the South Pole of the Moon.
    • Poles of the Moon as not too cold as on Mars, and that's where mining is possible. You won't need to heat solvents too much.

  9. Re:Why is some software more secure than others? on OpenSSL Security Vulnerability · · Score: 2, Interesting
    In this case the failures were mostly in the error handling, and any developer knows that this tends to be the hardest part of your program to get right. Not only are there a lot more ways things can fail than go right, but they can fail in many more places in your code and it is very difficult to make sure your program can recover gracefully from everywhere something might go wrong.
    I always wanted to have better support for error handling in C. Programmers should not be forced to handle errors by nested if's, "goto error" and wrapper functions that do nothing but check the result of another function and do cleanup. But please don't offer me C++ or Java. If OpenSSL is written in C, that's for a reason. Compatibility with all other libraries, relative independence from the compiler, native speed - those reasons cannot be ignored. If C is good to write secure software in it, I want exception handling in C.

    Magnetic flux density is local by definition and it's measured in Tesla. Magnetic field of Earth is 1/20000 Tesla. Jupiter has magnetic field measuring 1 Tesla in some locations. The Tallahassee magnet produces 500000 times stronger field than Earth.

    Magnetic flux is magnetic flux density multiplied (or integrated) by the surface. The unit of magnetic flux is Weber. That's where Earth wins over all man-made magnets.

    It's not just blatant lies. It's racket. Unlike other registrars, Netsol (now VeriSign) actually has technical means to "expire" your domain name from the nameservers if you don't pay. Netsol could easily do it and then claim that they "forgot" that the domain was transferred to another registrar. A notice from another registrar could have been ignored without much fear to lose the domain.

    I'm assuming VeriSign was lucky to have such an "understanding" plaintiff.

    Class action lawsuit would be more effective if the users sued to recover fines they paid while using the software.

    Currently, users don't lose any money if their systems are infected (except some malicious viruses that erase files), and sysadmins of the attacked systems are not necessarily customers of the maker of the unsafe OS.

    Ultimately, it's the users who are responsible for their choice of the software. If they feel they were mislead by software or hardware vendors, they are welcome to sue.

    Yes, that could affecxt Linux vendors who use deceptive advertizing, and that's a good thing.

    What's the point in scrapping the ISS and building another one in a higher orbit? Wouldn't in be better to boost the ISS into a higher orbit once we have the capability to get people there.

    Actually, I remember reading that most space junk is located on the orbits just above the ISS, so boosting it could increase the risk of debris penetration.

    It's also worth noting that the heavy lift rockets are not man-rated. Titan is quite unreliable, and the heavy versions of Atlas and Boeing are yet to fly. They will consist of 3 booster cores. If one of the 3 fails, the mission fails. The spacecraft would need to be able to separate and land safely if it happens.

    It's a major limitation - either the spacecraft has wings or it cannot carry heavy payloads, so that parachutes or rockets could slow it down for an emergency landing.

    We should have positive and negative modpoints, as explained here. If you ever posted on kuro5hin, perhaps you noticed how hard it is for a comment to stay on top, because it's so easy for everyone to rate it down. Here, modpoints are so hard to get that you won't spent them on stupid +5 comments unless you are offended or too bored to read comments with lower ratings.

    The K5 moderation won't work here because it's too prone to abuse. But separate modpoints can make the difference.
