Where does it say carbon neutral in the article?

see more

Anything that doesn't reduce some large stable store of carbon (extracting oil/ng/coal/forests) is at worst carbon neutral. If this leads to the development of huge algae farms it may actually be carbon negative during the ramp-up as a bunch of atmospheric carbon gets stored in the new biomass.

If BFR is even close to the specs that have been stated, it seems kind of crazy to think of SpaceX not doing at lest one moon landing. For one, it seems like a no-brainier just to test out landing capabilities on something other than earth. They could also easily fund it by transporting up science packets from various players on earth that don't want to figure out landing vehicles.

Conceivably any propellant price they offer SpaceX could be prohibitively expensive, considering their close rivalry. Hence SpaceX would probably prefer to make lunar propellant themselves, in order to more closely control cost, quality and delivery.

Possibly, but Bezos is a businessperson. He surely won't want to have BO producing propellant that only they get to use, any more than he wants Amazon to offer web services that only Amazon can use. He made his fortune selling stuff to people and other companies, and I expect BO would do the same.

I also think that BO is unlikely to be to crazy with fuel prices. One of their stated goals is to have a million people working and living in space. They don't say that they need those million people to all be BO employees, they seem genuinely interested in creating true infrastructure.

That being said, it is a business and normal economic principles will apply. They are unlikely to offer fuel at discount prices, just something that makes it very competitive compared to bringing fuel up from earth. This kind of gravity-well vs in situ economy will probably keep prices relatively high until cost to orbit drops another few orders of magnitude beyond what we get with full rocket re-usability with something like an orbital ring.

  • It get's easier, but people always tell me it get's harder later, so, I have that to look forward to.
  • Remember that they are people, they can be super cool, they can also be assholes, they switch back and forth often.
  • It's OK not to be prepared, nobody is. That goes for when you first bring them home all the way to what goes in the diaper bag. For our first kid we had a backpack loaded with changes of clothes, food, bottles, diapers, wipes, books, etc. Now we have like one diaper thrown into my wifes purse and some more stuff in the car.
  • I don't know what we did before baby wipes, I think they are staying around forever.

I think if we get to the point where an AMA doesn't get at least 20-30 good questions then we may want to consider walking away from them, but I don't feel that they need to even make it to r/all, as long as we aren't wasting the time of the person we are bringing in to do the AMA, it doesn't require 1k comments.

Instead of asking people to upvote, we can just ask people to ask questions.

I haven't seen humans. As for Westworld I think that you nailed it in the list. I would just make the point that Westworld only uses sentient robots as a way to tell a broader story, it isn't really about the singularity or even AI as much as it is about what humans would do if they thought there were no consequences (pretty dark interpretation of human nature), but of course, there are consequences.

You clearly missed the whole point of the first season ending and what is going on from that point onwards.

see more

How so? The 'hosts' in Westworld are designed to be almost indistinguishable from humans. The 'problem' is that they are too human. They are fundamental robots, but the story is dependent on them being essentially human. This became even more the case in the new season, now they can die, and nobody is actively programming them.

I'm not trying to argue that Westworld isn't an amazing piece of science fiction. Just that the story is more about how humans can be inhumane and that slaves can rise up against that, not about how AI and the singularity is going to change society.

Stunning!

I'm new, so sorry if this is obvious, but is that a ceramic pot (for stove top)?

It's an enameled cast iron dutch oven, so you can use it in the oven or on the stove.

Made two loafs last weekend, here's the album: https://imgur.com/a/JkXxwax

I was busy last week so I did a much longer total ferment time, almost entirely in the fridge.

  • Morning of day 1 - feed starter
  • Evening of day 1 - autolyse for 30 minutes -> mix in salt and starter -> wait 30 minutes -> fold, wait 30 minutes -> fold -> into the fridge
  • Evening of day 2 - pulled out of fridge -> fold -> wait 30 minutes -> fold -> cut in half -> shape -> wait 30 minutes -> second shaping -> wait 10 minutes -> 3rd shape -> wait 10 minutes -> place into bannetons dusted with rice flour
  • Morning of day 3 - take out of fridge -> wait 3 hours -> still not proofed enough -> wait 2 hours -> still not proofed enough but I'm impatient, preheat oven and dutch oven to 500f -> score the loaf drop into dutch oven, put on lid -> wait 10 minutes -> drop temp to 450f -> wait 20 minutes -> pull off lid -> wait 10 minutes -> take out of oven and repeat with second loaf.

Recipe:

  • 200g starter (whole wheat 70% hydration)
  • 765g water
  • 1012g bread flour
  • 23g salt
  • total weight 2000g
  • final hydration 75%

The bottom is slightly burnt, but the top seems perfect. How do I fix that? Less Dutch oven preheat?

see more

What temp do you bake at? Do you keep it at the same temp the whole time?

I preheat to 500, but after the loaf has been in the dutch oven for about 10 minutes, I drop the oven down to 450. The main reason I do that is so that the element isn't on the whole time it's baking.

+1 as long as we have a clear and specific definition of tabloid.

love seeing progress pics !

Just recently got into making sourdough. I've gone through bread making phases in the past, so I had some equipment around, such as bannetons and a sweet lame that I had never used before.

I did some algebra and put together a little calculator for myself to adjust my recipe and solve to the variables I'm interested in. Check it out if you want, you should be able to edit the yellow cells. If you have any issues please let me know, I haven't shared a spreadsheet before: https://docs.google.com/spreadsheets/d/16xEwXoXIvYad-6-ztUqd0SrQSGaldpyWAFjMRtBM17g/edit?usp=sharing . I'm playing around with some other driving variables, can't decide how I want to adjust my starter. Currently it is represented as a percent of final dough weight, but I could do it as bakers percent of added flour, bakers percent of total flour, or as the percent of total flour that originates in the starter (leaning towards this).

Some of the details are in the album, but I didn't go into too much detail, so feel free to ask questions.

Things that you may wonder:

  • Starter is whole wheat, playing around with it's hydration
  • Remaining flour is american bread flour
  • I bake in a dutch oven - 10 minutes at 500f, 20 minutes at 450f, 10 minutes at 450f with the lid off.

Let me know what you think. Thanks!

This was my first time baking with a dutch oven, and it came out absolutely incredible! Delightfully crisp crust with a soft inner. I'll never go back to the baking sheet and pan of water method I've been using till now. I highly recommend a dutch oven if you have to use a conventional oven for your bread.

looks yummy, do you have a pic of the crumb?

When I started getting into DIY stuff around my house I realized that most of the DIY people from my dad's generation had no idea what they were doing. A lot of stuff ended up being downright dangerous. Thanks to YouTube I have a lot more confidence that I'm doing things to code and benifiting from other people's mistakes.

Probably too late to the party here, but how has nobody come up with the right answer? The question isn't "what movie was better than you expected it would be."

Jaws

Jaws is the right answer, and is also the best evidence of how amazing Steven Spielberg is as a storyteller. A movie about a killer shark has no right to be that good. Put it next to every other killer shark movie if you need proof.

There are only a couple of things that would explain why the booster beats the capsule back to the landing pad. Either it is more aerodynamic (slowed down less as it falls through atmosphere) or they are separated with some small force which would slightly increase the capsule's upward velocity while slightly reducing the booster's upward velocity, a small change up close to apogee would actually put them down pretty far apart, so I lean towards that as the answer.

You have to think about what forces are applied to each body after separation, gravity will apply the same force per unit mass on each, so one being lighter than the other doesn't change anything.

These guys are physically radiating with asshole-ness

I think what's frightening about these pictures is that these guys probably weren't exceptional assholes, just your average young American white men at the time. This behavior was just them fulfilling a social norm. I wonder what we do now that will be looked at in this way in 50 years. Makes me uncomfortable.

I find it to be more polarizing among Culture fans than Player of Games, but the people that love Use of Weapons REALLY love Use of Weapons.

I don't understand why it isn't everyone's favorite. I love use of weapons.

Thanks for contributing. However, your submission was removed from /r/Futurology

Rule 2 - Submissions must be futurology related or future focused.

Message the Mods if you feel this was in error

-1 for blanket duplicate removal within 7 day window.

+1 for /u/sirt6 idea. I don't think it should be considered a repost at all if the first post has less than 50 upvotes in the first 6 hours or so.

You have two classes of reposts.

  1. Breaking stuff that has a lot of nearly simultanious posts (covered under existing rules)
  2. Things that poster finds interesting several days since anyone else posted (I don't really see this as a problem)

As of python 3.6 you can also use f strings instead of .format. So instead of "This text is variable: {}".format(variable) you can just use f"This text is variable: {variable}" . I find it much easier to keep track of what is going on.

Maybe we should just require better documentation and remove any sites from the list if it isn't clear why they are on it. If a reason is given and somebody disagrees with it, then we are at a place where we can have a discussion.

Obviously we should give mods a chance to go through and annotate the banned sites before we go through a blanket unban, but ultimately, if we don't have a note as to why it's banned, it shouldn't be banned.

Careful, this bundle is by Packt. Meaning it's quality varies from "decent" to "outdated crap". It's still much better than nothing obviously but there are better resources as well. So if you find one of those books hard to understand then it's not necessarily on you, might very well be on them.

Here's free course on Coursera, courtesy of Stanford University and made by a guy who actually worked on cutting-edge AIs at Google. If you are interested in stuff like self driving cars, OCR etc then it's one of the better resources currently available:

https://www.coursera.org/learn/machine-learning

Do note - this is mostly a field of math that uses programming, not the opposite. Meaning that you will probably need to refresh (or learn from scratch, Khan Academy is useful for this) your linear algebra knowledge to some degree (it is shown in this course as well but it might be a point you can struggle with).

Also - do note that this Humble Bundle pack has 3 tiers, most expensive one (with all the books) for $15. I suggest paying a bit more to have a complete list.

see more

Coursera also has a more recent deep learning specialization that is taught by the same guy (Andrew Ng). I'm taking it now and it is pretty awesome. Taught in python using jupyter notebooks.

https://www.coursera.org/specializations/deep-learning

I think that last time we tried this (years ago), we found that stickying a post actually ended up hurting the organic growth. The algorithms have changed a lot since so maybe it wouldn't be an issue any more.

Overall it would be awesome, anything to increase the 'community' feel by encouraging conversations.

Um. I was under 100 in May 2017, December 2017 and February 2018. I don't see how that is 2 times in a row.

Either way, I apologize for my lack of activity recently, getting into the groove of a new job and haven't figured out my mod schedule yet. Good news is that I actually should have more time to mod than I did before once things settle out. I would appreciate it if you could give me another chance.

+1 from me

I suggest downloading a reddit app like 'reddit is fun' and just mod comments on the fly every so often.

I usually approve like 20-30 posts within a couple minutes every blue moon, in addition to the occasional comment modding. It's very easy to hit 100 a month.

Yeah, that's actually what I usually do. just been in a job transition so my normal routines have been out of whack. Should be able to pick it up going forward.

Ok, I'll re-approve. Sorry for the inconvenience.

As much as I hate overdraft fees, PMI is probably the sleaziest fee I pay.

I'm confused as to what banks risk when they finance a mortgage given that they are operating in a fractional reserve system. What kind of risk does PMI protect them from?

Let's say they loan somebody $1,000,000 for a home of the same value. The person defaults, the bank now owns a $1,000,000 asset and they have the same lending power as before since it doesn't reduce the reserve. I know I must be missing something here because it seems like this system would directly incentivize bad loans.
