    Yeah, we can ship a few people someplace far away AKA Captain Cook (or was that Captain Bligh?) but for having people living in Tombstone, Arizona, Mars is unbelievable, never mind having a McD, WalM, or Micky there to visit when you're bored.

    Well, even in his most generous projections of massive reuse at scale in the far future Musk said "The cost of moving to Mars ultimately could drop below $100,000" which is a bit outside my budget for a burger and it's for a one way trip. So yeah the people who expect warp drive-like bouncing around the Solar system have watched too much sci-fi. Same with the people thinking we have the capability of terraforming Mars.

    That said, getting to LEO is a lot of the effort to get into space and the difference between TLI and going to other planets even smaller. According to this chart

    Earth to LEO: 9.4 km/s
    Earth to TLI: 9.4 + 2.44 + 0.68 km/s = 12.5 km/s
    Earth to Moon: 12.5 + 0.14 + 0.68 + 1.73 = 15.1 km/s
    Earth to Mars: 12.5 + 0.09 + 0.39 + 0.67 + 0.34 + 0.4 + 0.7 + 3.8 = 18.9 km/s

    Towards Mars you can use aerobraking, which puts the rocket requirements more in the ballpark of the Moon. Granted getting off Mars again is quite a bit harder but it's not some impossible goal from a technological point of view with an Apollo 2 program and a Saturn VI. The challenge is finding some economically viable path to make it happen, but with SpaceX aiming for the third launch of a Block 5 rocket this year they've hopefully turned the corner on that and the 4th and 5th is not that far behind. And 2019 will hopefully see a crew rating of the F9 too.

  3. Not unusual mark-up for oddities on Air Quality in San Francisco is So Bad that Uber Drivers Are Selling Masks Out of Their Cars (recode.net) · · Score: 4, Interesting

    In San Francisco, which currently has the second-worst-rated air quality out of any city in the world, one driver was spotted selling N95 respirator masks for $5 apiece. That's significantly above market rate. Right now you can buy a 10-pack of similar masks for about $13 on Amazon.

    Truth is, under most circumstances you'd always buy shit cheaper at a supermarket or whatever and often in volume if it's non-perishable. Which means there's very little point at selling something at 30% or 50% mark-up. I've paid 5 euros at a camping grounds on the weekend for a pack of batteries that would normally cost 1 euro. How often would that happen, maybe once a month? You're not going to get rich making 4 euros/month selling batteries. They still wouldn't sell well for 2 euros/pack. At some point you have to cease looking at "rational" cost and look at lost opportunity costs. I was there, out of batteries, the nearest proper store was far away and the alternative was probably to not buy batteries at all. It wasn't a trap or anything like that, it was just a duuuuuuuh moment as I realized all the batteries were dead.

    Honestly, I feel that this is sometimes the exact opposite of the sunk cost fallacy - we've spent tons of money to get here but then we're going to skimp on the last dollars to actually take advantage of it. Like you go to a foreign country with airplane tickets and hotel and whatnot but then it's like should we really go out to eat or just grab some snacks from the local store. And I'm like the opportunity cost of going out to eat at a fancy Greek restaurant is just the cost of going out to a fancy restaurant, we've already paid for everything else. Yes in isolation we can go to McDonald's and it's a lot cheaper, but in total we're then paying a ton of money for the same shitty experience we could get at home. If we ever wanted to do it later, we'd have to re-sink the cost of going to Greece so the opportunity is "cheap" here and now. So... if you're about to step of out the taxi and see smog hell, is $5 worth it? I think yes.

Now if he had some kind of metadata like say file indexes, project references etc. that'll help but otherwise he'll have an uphill battle trying to convince the court he lost anything at all.

  9. To be fair, that is only true in English. In every other language I know of, the equivalent word means 10^12 and 10^9 is called something resembling the word milliard. It remains confusing except perhaps to those whose mother tongue is English.

    10^6: Million
    10^9: Milliard
    10^12: Billion
    10^15: Billiard

    Fortunately we rarely need the word billion in Norwegian as that would be a trillion in English and because it could be ambiguous on the rare occasions we could use it we tend to simply avoid it like a thousand milliards, So practically it's like "billion" is the English translation of Norwegian "milliard", forget everything past 10^9 and the etymology as you'll only confuse yourself.

    No, the main problem is that the spoken word is fleeting and poorly searchable. If it's not recorded you have no paper trail of what was actually said and even if you do it's is much easier to find the relevant bits with a transcript or better yet a summary that omits all the irrelevant bits, that is why we have long discussions and try to make short conclusions. But it's exceptionally rare that I actually mishear something in a conversation, like I literally didn't understand the words. It may be that I'm struggling to understand what they're trying to explain, but that would probably be the same over Slack or Skype. I will agree that if you're in effect editing a document then trying to come up with a non-ambiguous specification is much easier in writing.

    Very common stories include people coming out of retirement after a year, people turning to alcoholism after retirement, people dying shortly after retirement (sometimes by suicide and usually with depression-related symptoms), and people volunteering a lot after retirement.

    Anecdotal stories yes, but most people who retire simply retire. The mortality tables show no jump or peak at general retirement age. They do more volunteer work but for most that's at a fraction of a full work week and quite possibly a way of winding down, not proof they need it permanently. In fact I just checked the stats here in Norway and only 39% of our retirees are active members in any volunteer organization. Only 30% claim to have done any volunteer work. Of course that covers all retirees, directly post-retirement is probably higher but most of our elderly do fine just being retired.

    They're just extrapolating though, like if you look at historic fertility rates in the US you might think in the 1930s that it's around 2.0, in the 1950s 3.5 and in the 1970s 1.8. Countries have had huge "mood swings" and despite being somewhat correlated with GDP, HDI and whatnot there's a lot of variation. The rate of medical advancements increasing lifespan the next 30 years is also far from given. Maybe someone will set off WW3, that'll throw all projections out the window.

    The main reason it's almost certainly true though is that you don't need huge changes from the status quo. People live a lot longer, have kids later and have fewer kids right now, unless there's a radical shift to pop out tons of babies again it's happening. Most western social security systems were created when we had few retirees, they didn't live long on retirement and there was a booming population to support them. The essential input factors have already changed, it just hasn't filtered through the system yet.

    Here in Norway they've fixed this quite easily because around 2010 most the banks introduced regional blocks, the defaults vary a little but my bank's card by default only works in Norway. To expand the coverage you must log in to the online bank and enable it.
