  1. Re:Planned Obsolescence on Steel Treatment Paves the Way For Radically Lighter, Stronger, Cheaper Cars (gizmag.com) · · Score: 1

    Before the days of unibody construction, usually the lifespan of a car was dictated by how long it took for the frame to rot, up here in New England anyway. I had a series of Subarus through the 1980s and 1990s that had perfectly running powertrains

    Um, those 1980s and 1990s Subarus all had unibody construction. The only 'cars' that didn't by then were American SUVs, which were built on truck chassis to skirt gas guzzling taxes.

  2. Re:Who is really financing this? on Faraday Future Selects Las Vegas As Home For $1B Electric Car Factory (autoblog.com) · · Score: 1

    a. The fact they haven't published a design yet doesn't mean there isn't one.
    b. In the car industry, a $1B factory is an absolute requirement if you want to, you know, actually build your marketable product. Introducing your worldbeater and then going "whoops, we forgot we need a place to build them, so come back in 4 years when we finish the factory so we can build more than this single hand-built prototype that cost $3M to fabricate" is not a recipe for success.

  3. Re:A rather large "destroyer" on Largest Destroyer Built For Navy Headed To Sea For Testing (ap.org) · · Score: 1

    The whole cruiser/destroyer/frigate nomenclature has become pointless with the advent of guided weapons. In the old days, a cruiser had much bigger guns and more armour than a destroyer. Now, a Ticonderoga-class cruiser has the same armament as an Arleigh-Burke class destroyer, the Tico just has more missile cells and can track more targets simultaneously.

    Also, there's been a trend to make ships much larger for the same initial functionality. The extra space isn't expensive to add, and it tends to come in handy later on (it becomes easier to retrofit new systems, for example). The Dutch navy found that their new 6,000-ton hulls were cheaper to build than the previous 4,500-ton design just because the old design was highly optimized for space, with lots of irregularly-shaped rooms to fit the equipment exactly. The new design has standard rooms so it became easier to build, with fewer specialized parts needed.

  4. Luck or wisdom? on Japanese Space Probe Akatsuki Enters Orbit Around Venus Five Years Late (space.com) · · Score: 5, Interesting

    They can do this attempt because when the original orbit insertion failed, Akatsuki entered a heliocentric orbit in an 8:9 orbital resonance with Venus, making sure it'd meet up with Venus eventually. I haven't been able to find if that was a happy coincidence or if the initial approach to Venus was designed for this contingency.

  5. Re:Why are there so few? on Japanese Space Probe Akatsuki Enters Orbit Around Venus Five Years Late (space.com) · · Score: 1

    For interplanetary missions, launch weight is a big limiting factor. Sending 2 probes would have meant 2 launches, making the mission much more expensive.

  6. Re:Define 'monstrous' on Astronomers Spot Baby Galaxies Cradled In Dark Matter (phys.org) · · Score: 1

    Even 'n times larger than the Milky Way' would be better than "monstrous", which gives no information at all.

    TFA uses an annoyingly vague term and fails to define it. How large are these galaxies?

  8. Disconnect from geography on Providing Addresses for 4 Billion People Using Three Words (mondaynote.com) · · Score: 1

    Many of those 4 billion people already have a partial address: the city or village they live in. This system throws that out.
    Their algorithm also seems to be random. You'd expect people in one city to have part of the address in common, but the example shown doesn't do that. So there is no way for a human to estimate where an address may be. Horse.battery.staple could be next door to you or on the other end of the country.

    Traditionally, address systems have been worked out by governments and/or postal organizations. At their best, they provide amazing accuracy. In the Netherlands, a single 7-to-10-character code (6-character post code plus house number) provides 100% address resolution.

    Some systems are less robust. I can believe the UK example (£775M in incorrect addressing cost). In the UK, addresses use 3-6 lines of text because the UK Post office didn't introduce universal house numbering (so you have to identify houses by name), and because traditionally there are up to 3 names for the village/neighborhood/region.

    So there is plenty of room for improvement. But I don't think this is the way to go.

  9. So do we need to revise our estimates? on More Than Half of Kepler's Giant Exoplanets Were False Positives · · Score: 1

    Does this mean there are lots more binary stars than we realized?

  11. How to make information worthless on After Demanding $3 Million Ransom, Hacker Dumps Massive Customer Financial Data (dailydot.com) · · Score: 1

    I was thinking about ways the bank could have mitigated the effects of the attack. Would it be worth releasing piles and piles of false identities? Generate so much noise that anyone who'd want to use the data would have no way to separate the wheat from the chaff.

    It doesn't matter on which grounds the protest group objected to the permit. They were not heard, and that's what the Court ruled on.

    This ruling has nothing to do with religion. Due process was not followed when the permit was granted. The university is free to apply for a permit again.

    Where are they going to sink that excess electricity? Spinning up servers just to let them sit idle is pointless, you might as well dump the power into a resistor bank. Low-priority grid computing, maybe?

    Placement of Ctrl, Alt/Option, Cmd and Windows keys.
    For a Mac, you want Cmd next to the spacebar (for easy access to the most-used shortcuts like Cmd-X/C/V) and Ctrl off to the left somewhere. For Windows, Ctrl needs to be next to the spacebar.

    I've got a Windows machine and a Mac running off the same keyboard (KVM switch). Switching is a pain. I've experimented with key remapping software, but haven't found a program that would swap keys only if keyboard 'X' was attached.

    the idea of the information escrow is to reduce students' fears that the first person to make an accusation could face undue repercussions.

  24. Re:Pedantic but... on Huawei Battery Upgrade Means Dramatically Faster Charging For Mobile Devices · · Score: 1

    No, they're taking advantage of the different molecular structures possible with carbon. Which (and that was my point) means it does make sense to talk about graphite vs. carbon, even if they get the word 'atom' wrong.

    Quoting an answer from elsewhere in the discussion:
    "Introducing extra carbon atoms into the graphite anode to create artificial fault sites in the graphene sheets, allowing lithium ions to enter through those locations into the interlayer space instead of having to enter from the sides of the stack."

  25. Re:Pedantic but... on Huawei Battery Upgrade Means Dramatically Faster Charging For Mobile Devices · · Score: 1

    Apparently, there is a difference. This paper for instance lists graphite and carbon separately as anode materials. So I'd guess the "crystal" structure of the various forms of carbon does make a difference.
