    Probably because given a standard pie's radius (around 6 inches) then using 3 provides a circumference which is accurate to roughly 1.5".

    Good lord, where did the time go. I thought about it for a bit and realized it's been 30 years not 20. In my mind I'm still 23, the fact that I have a son that's over 30 is kind of beside the point.

    I don't know about focusing particularly Boolean logic but I've been a proponent of at least a one year logic course for a long time.

    I'd focus on more practical aspects of logic, the kinds that you see poorly displayed on places like Slashdot every single day. e.g. paradoxes,inductive vs deductive logic, false equivalences, predicate logic, propositional logic, forms of cognitive bias. For the latter I mean things like selection bias, confirmation bias, though I know it would be an uphill fight as folks wanted to turn it into a 3 month seminar on specific forms of gender and racial bias.

    Frequently people conflate logic with 'what kind of sort of makes sense to them at the time or sounds ... you know ... right'.

    Some of the fired professors were fired *because* of their SJW proclivities. They were offended by something some autocrat said, spoke out and the autocrat fired them. Are you going to defend them even though they're special little snow flakes whose feelings were hurt by the idea of drowning little bunnies or do you approve of their firing ?

    Free speech is free speech, it's not limited to just those you agree with. If you're truly that concerned about free speech then defend free speech. If you're more concerned about defending your personally held beliefs from the SJW crowd that's fine but don't conflate it with a general love of free speech.

    For what it's worth I like the analogy and wholeheartedly agree with the idea of drowning the little bunnies, increasing retention at any cost is a dumb idea but the factulty shouldn't have been fired for being offended.

    They haven't been given a 'lawful order' they've been given a 'strongly worded request'. There is precedent for what Apple is being asked to do and the precedent is they can say 'fuck off'.

    They're not being asked to present data they have access to, they're being told to provide a mechanism to extract data. Picture a tech company that specializes in image manipulation and they make cameras. One of their cameras has a security still of a suspect. The government can ask that they turn over the still, they can not compel the company to write new software to manipulate that still.

    The govermnent has the phone, in fact there's evidence they borked things up by attempting to change the password. They want the data on it they can knock themselves out. If they succeed in extracting the data then phone manufacturers need to step up their security. If they fail then things are working as intended.

    This is a fairly significant problem for parts of Northern New Mexico through Central Colorado. I think though that it's kind of the opposite timing from what you describe. The Spruce Beetle larvae are spawning at an earlier time. The eggs of birds who primarily predate on them to feed their young aren't hatching early enough (they're hatching earlier, just not early enough) and are actually dwindling due to starvation while the infestation gets larger. The pine beetle infestation is even worse.

    It's rather stunning to see mile after mile of dead forest in parts of central Colorado.

    Ok from a pedantic view then I agree, it would be exceedingly hard to rebuild the SaturnV. But that's the wrong question because building a SaturnV is only interesting from a historic perspective. The real question is have we lost the ability to build a high mass launch vehicle and the answer is definitely no.

    The SaturnV had a 140,000KG mass to LEO capability. The Block-2 will have a comparable 130,000KG mass to LEO capability. Admittedly there's not one sitting on a launch pad right now but that's because there was never a need for it. Now that there's a perceived need we're building one. It's in the design and testing phase now but that's because they are in fact bloody complicated.

    The whole 'we can't build a SaturnV' meme is interesting as a testament to the failings of compartmentalized design and poor record keeping but it's not evidence of some lost technical ability. We're not any dumber now than we were 50 years ago, or smarter for that matter. About all one can say is there's more headwind now from bureaucracy than there was 50 years ago but that's a process problem not a technical problem.

    What do you mean by gone ? Once somebody has the bright idea of using round things to move other things the process of re-inventing the wheel is trivial. It's definitely frustrating to watch folks re-invent it but it take progressively less effort.

    You make it sound as if they couldn't build the Saturn now if they had to, what you really mean is they can't simply start manufacturing it. The design concepts are not 'lost'.

  19. Invalid comparison on One Hoss Shay and Our Society of Obsolescence (hackaday.com) · · Score: 1

    The One Hoss Shay comparison would be valid if:

    - Genetic engineers were madly trying to evolve a horse and still debating how many legs it should have.
    - Mechanical engineers were still debating the optimal number of sides for a wheel. Somewhere between 3 and a lot.
    - Structural engineers were still debating whether the frame should be made out of stone, iron, transparent aluminum or wood
    - Behavior scientists were still debating what direction was best to drive the thing in and which orientation. Landscape or portrait driving mode

    Obsolescence of parts is uninteresting when they have a half life significantly greater than their practical application.

    Designing a One Hoss Shay in 1905 that would last a hundred years would be very useful for about 5 to 10 years. Then everybody will trade it in for a Model-T, 20 years later for a Model-A, after that figure 5 to 10 years as a function of economy.

    It would not make it more secure. As the GP pointed out rm is just an example. Adding a user level hoop to jump through doesn't fundamentally change the nature of the problem. Root should be able to write to any filesystem exposed to it in read/write mode. The problem is it shouldn't have read/write access to that area . period . hard stop.

    If you want a secure system then it's the data owners job to decide who does and doesn't have access, not to grant access to everyone and hope they do the right thing. In this case it's 100% UEFI's fault for exposing it's data in read/write mode.

    On a related note how does 1st and 2nd century BC count as "Ancient Babylon". That was toward the end of the Hellenistic period of what was barely left of Babylon. Ancient Babylon by archaeological standards (to avoid conflating it with any number of other empires that just happened to share the same geographical area) had ended some 1000 years before. In fact the article suggests that the 2nd century BC tablets were actually copies handed down from as far back as actual ancient Babylonian mathematical texts in or around 1700 BC. Which is quite a bit more interesting.

    So what they really mean is Persian mathematicians during the Hellenistic period in the area that was known as ancient Babylon and now modern Iraq, but I guess that doesn't have the same ring.
