My reading-related startup did a study recently and found that — even among our relatively techie users – there is still a strong preference for paper books over ebooks. We were really surprised at the magnitude of this preference, given how tech-savvy the respondents were.

Conversely, if this helps one portion of the economy that greatly then it will surely benefit the entire economy even more - or at least equally.

Precisely why I would say this should be a governmental system of bare essentials living and housing. Every dollar spent on people with nothing will be spent by those people and increase aggregate demand, economically, and health, at a societal level.
You could argue that they're biased, but you could also argue that they're the most knowledgeable people available.

If you don't like those sources, look around. There are lots of government studies in many countries available.

If you are willing to read them, that is.

That's true but the profit margin grew for publishers. We don't see the same comparative price reduction in electronic books. And this reminds me of what happened with CDs, they were easier to physically produce than tapes or vinyl and yet they went up in price.
One good thing is we do have free e-books, thing that was not physically possible with paper books, the production had to be paid by someone at some point. On the other, electronic books are ephemeral, are locked into whatever platform/device and are bound to render useless as time goes by.
Landfills are actually better, in that in many cases commercial operators can recover the gas and turn it into renewable fuel.

Scope uncertainty is always larger than the certain part. It's often nearly all of the scope.

Technical uncertainty is also more common than not, unless you are using a dying platform, it will change between the estimation and implementation.

Human uncertainties are an avoidable one, if you work alone. If you are in a team, they are also certain.

Or, to put it shortly, yes it's perfectly possible if you are doing a university project alone in an old platform without an active community.
With current energy grids that are used in the world as a template, you can have one of two grid.

1) Nuclear, with the high building cost and externalization of spent fuel.

2) Renewable, with cheap building costs and externalization of variable production rate which is solved by burning fossil fuels like natural gas or coal.

If we look beyond current grids and look into the future there is solutions to those externalizations. Renewable could use batteries rather than burning fossil fuels, but the current best bet is to build enough hydro powerplants and dams to fully support the energy grid during low production periods, and pumping back the water during high production. This will cost a lot of land and put a lot of greenhouse gases into the air, in particular because putting a lot of land under water tend to create a lot of methane. The cement for the dams are just like the cement in nuclear plants a major contributor to greenhouse gas production.

Personally, I just would declare that the age of burning fossil fuel to manage the energy grid has come and passed. By 2020 we should not build any new natural gas power plants. by 2030 we should have decommissioned 90% of all fossil burning plants, and by 2040 a complete ban of burning fossil fuel for electricity for any scale larger than a hospitals backup generator. With those decision in place I trust that investors will figure out if nuclear is profitable or not, and I personally do not care. For the climate sake my only wish is that we stop burning fossil fuels.
That sort of undermines some of the carbon arguments used against recycling.
If it's an economy-wide crash, the opposite is more likely: a reduction in interest rates.

People who oppose investing in nuclear who, in the same breath, claim climate change is the greatest existential threat to humanity, reveal just how seriously they take the climate threat. If we had an inbound asteroid headed to hit us and there were technologies we could deploy to mitigate it that had potentially large negative downsides there would be no hesitation. In this case, hand wringing over the threat of nuclear implies the threat of climate change is not being taken as seriously as one might think.

Uhhh, I think you may want to rethink that. Rotting things, whether in a landfill or in your ecologically principled compost heap in your back yard releases methane.

I don't know where they got their numbers, but they're saying that home price of a $1000 rental is $421,080 which is absolutely insane for Seattle. 3 Years ago when I was shopping around shitty apartments were $1500+, with decent apartments and houses renting for $2000+ easily. One of my family members rent out their $400,000ish house for something like $2200-2400 a month. You won't be able to find a $400,000 property to rent for anywhere close to $1000. My house was listed in the 200s, sold for 12% over asking, and has appreciated nearly 50%. If I ever move my house will rent for over $2000 a month easily and it's quite old and not even in Seattle proper
I'm coming around to a similar viewpoint. But I'd say it it's looking bad for building new nuclear power plants, we certainly want to try to keep running our existing nuclear plants until we get rid of all of our base load fossil fuel power plants.
That is not nearly the same issue. It is a relatively tiny few airplanes with very high numbers of legs, i.e., landings, which is the most likely culprit (exacerbated by hard landings of inexperienced, low cost pilots). And most of the grounded planes seem to just meet lowered inspection thresholds; many of which will simply enter service again after inspection.
> Are you suggesting hiring employees to check every single listing on AirBnB?

Yes.

Unless they don't actually plan to verify listings, in which case they should just state they don't verify listings. Then they don't have to hire anyone extra.
Skepticism is healthy and is the essential posture of the Scientific Mind, and is not remotely the same as denial. The cherry picked time series used by the Met are clearly 'bad science' in the name of something 'ostensibly good'. FYI the intellectual authoritarians are much scarier than the skeptics, usually, in the long run. I wonder if this discussion should be more about communications strategies than material science.

Simple: because at high levels of intermittent penetration, you have to build so much "non-productive" storage technology that the Energy Return on Investment is below the level thought necessary to sustain industrial civilization. For example, this was just published last week:

Depends on your perspective. Yes, if you are an application developer with weaker skills to access the data integrity logic in the database. No, if are a skilled database guy with weaker knowledge of all the source code of all the applications (could be multiple) sharing the database. Things are happening and it takes forever pouring thru each app's code to find its data integrity logic to figure out why they are happening.

By centralizing data integrity logic in the database, you know where to look and that all apps using the database will abide by it.
A year ago I had bluetooth headphones that would call out mileage stats during my run; pausing my audiobook in the progress. I recently replaced the headphones with a newer model b/c battery life degraded on the old pair; and also recently upgraded to android 10 on my phone. But now instead of getting a full report of distance, pace, and time, I get distance followed by 5 seconds of silence. Not sure if it is the headphones, Android 10, audiobook app or workout app, but yeah, it does totally seem like software just gets worse over time.
My wife and I bought a condo this past year. It's working for us at the moment, but getting an offer accepted without breaking the bank was the hard bit. We got our offer rejected, then someone else reneged on an offer, and then we were asked to fucking match their offer. We had to go up from our original, which was already quite sufficient, just to get it accepted, and even that was by luck! It was something like the third place we'd offered on.

Contrary to popular belief, quad engine planes are not inefficient [1], at least not in terms of fuel consumption (we are talking 1% to 2% difference). In terms of dispatch reliability however I think they are doing somewhat worse than twins, as they are more likely to have one engine out of service. And it not a small problem: a plane flying revenue passengers is an asset, but a plane not flying is a liability.

At least two of the planes you list are not being phased out because they were quads. The A340-300 was doing very well against the 777, however the A340-600 did very poorly against the 777-300ER. This is because the frame was too long and narrow, requiring extra reinforcement not to bend, thus ending up much heavier than the frame of the 777. The frame itself was grossly overweight, the extra engines were a rounding error.

The A380 was (and still is) extremely efficient (in terms of fuel burn per seat, at equivalent seating density), with a fuel consumption similar if not better than that of 787s or A350s, despite engines one generation older. It is, however, way way too big. In the end flying empty seats is very inefficient. But that has little to do with having 4 engines instead of 2.

The re-engined 777-9 will certainly be the most efficient plane flying when it is launched in 2021. Yet sales are lacking. It may, like the A380, turned out to be too big.

This is profitable goodness. This is what we should strive for as a society. I imagine it was quite a battle for the people who suggested this strategy against the naysayers. Listen to them here in this thread.

> It is very hard to measure the reduced life expectancy due to radiation.

No it is not. The ability to fairly precisely calculate cancer risk over time based on radiation exposure is exactly how we get the death numbers for nuclear. It's basically no different than calculating deaths from other airborne pollution except that radiation gives you cancer whereas coal soot (for example) gives you lung problems.
My dad has been a once or twice a week movie goer since I can remember, sometimes with my mom sometimes without. But since I bought him a 49" Roku TV, he goes to the movie a lot less often. He has Netflix, Amazon Prime Video, access to my Plex Server, Crackle and the Roku Channel. He would have access to a lot more if the other network provided apps didn't keep forgetting his cable login and force him to validate by going to a website.
A lot of "ought" in what you're saying, but there's a stark reality that clashes with that ideology, and it's how little you can control others.

The difficulty with the approach you propose, and by contrast one of the major strengths of SQL, is composition. Passing a list of column names and a list of conditions lets you express precisely two concepts: Filtering and Projection. You could also add more: A set of tables to join together, an "aggregation" version of the same operation, etc... Going down this path, however, leads to a monolithic function that becomes progressively harder to generalize.

What relational algebra (and by extension SQL) gets "right" is that each of these operations (Projection, Filtering, Join, Aggregation, Union) are composable: They take 1 or 2 collections as input and produce a collection as output. Moreover, each operation has simple and well-defined semantics from which you can build much more complex logic.

That's not to say that Relational Algebra can't be built in to an imperative language. Scala (and by extension Spark) collections are a great example of composable operators at work. Ruby's array methods, Python comprehension syntax, and Pandas/NumPy are similar examples of simple, composable primitives that combine to be much more powerful data transformations.

Apart from RA-based language primitives, there's also compiler support that allows you to use SQL directly, but avoid passing strings around at runtime. .NET's LINQ is a great example. I'll also pitch one of my own projects, DBToaster (https://dbtoaster.github.io/), which compiles view maintenance queries down to a C++ or Scala class.

In short, I agree that passing strings around leaves performance on the floor and leads to escaping and code injection nightmares. But SQL is the culmination of literally decades of use-based design, and any effort to replace it needs to take care to understand what it does well and why (like the efforts I reference above)
I feel like a system that discourages young, healthy and educated citizens to not have children until they are much older... is screwed up. Especially since many of those with student loans are not finding jobs that would pay them off before the end of their child bearing years.
I'm about your age, I also live in Seattle. Though, I do have a partner and a dog so that makes some difference. I chose to buy a home and I'm quite happy with it overall. It's a good place to have people over since it's much larger than the average apartment, I don't have to move every year or so to fight the rising rent, I have plenty of space for projects and storage of various hobbies. My family doesn't have to stay in a hotel when they visit because I have a spare bedroom now. I've also learned a ton of skills related to home ownership such as basic construction, electrical work, etc. which can be a plus if you're into that sort of thing. I prefer the quiet of the suburbs as well.

That being said, my commute is atrocious. It's about 1.5hrs each way into the city. Even so, I feel it's worth it. But obviously may not be for everyone.

Personally, I wouldn't look at it as an investment. It's more a lifestyle thing that you've gotta think you'll be happier with. My mortgage is the same as my rent was at the time, so I thought I was netting out just fine, but houses have a lot of expensive maintenance events that pop up and will put you in the red pretty quick if you're not careful. For example, my heat pump and furnace went out recently which will set me back several thousand to fix. So, while you're building equity in something, there is a hidden cost with that. Worth being aware of.

Hope that helps.
Vaguely similar boat! Northern NJ though.

I'm 24 and became single about 6 months ago. After this happened, I moved out of my family home to rent closer to work, which cut an hour off my commute. It's been a mixed bag financially and I've been borderline paycheck-to-paycheck (I do max my 401k, so it's more of a self-wrought liquidity issue).

My thoughts:

- I'm really getting punched down by the 20% down payment standard. I know PMI is a thing, but it's a fee that I'd like to avoid paying in addition to interest. Assuming 20% is enough to avoid PMI, even if I snag a 600k condo I need 120k down to not have a PMI.

- I don't entirely know that I'd like to commit to this area, but I know I want to buy at some point, and I'd like to believe that snagging a property sooner than later will at least give me some leverage for a future purchase via the equity in the property. One of my friends bought a studio in FiDi for similar reasons- he'll probably break even in the `rent v buy` scenario but will at least have some sort of fund to fuel his next purchase via the equity in the apartment.

- This is also a game of forecasting your income for some period of time. I'm in software development, which seems stable for now (I hope), so I'm pretty confident in my ability to eventually pay off a high mortgage.

In the end, I have no hope of buying a place right now, all I can really do is shove money into a MM savings/mutual fund and wait around until its worth enough to convince a bank I'm worth their time.
I took a long time looking for a home, precisely because I was unwilling to accept a long commute. Buying a house is not worth a 45 minute commute.

Leaving aside the considerable additional expenses of commuting, and the missed health benefits of a 20-minute walk every day, you're now talking about spending 70 extra minutes per day commuting. That means 5 hours and 50 minutes extra commuting per week (total of 7.5 hours), or about 12 extra 24-hour days of your year spent commuting.

You currently live 10 minutes walk from work. Don't move to 45 minutes drive/bus from work. That's a substantial chunk of your life you won't get back.

And as other replies have pointed out, in the area you're in, owning may not be a win for you.
The concept you are looking to read up on is servant leadership. It's entire thesis is that a leader serves those "below" them.

> If the MCAS had informed pilots of a potential sensor failure, then there would have been a very good chance that the pilots would have been able to land the planes safely.

Perhaps on the two crashes. We don't have any data on successful landings with MCAS disabled in very adverse flying conditions.

What if the plane is unsafe to fly without proper MCAS operation?

There should be a test that results in a plane crash with 50% of the simulations with MCAS behaving properly (IE, extreme weather, low fuel, land or die). Now during that same simulation, disable MCAS randomly. Also, there seems to be potential for the MCAS to come in and out based on disagreement (loose sensor wiring, etc), and see what the crash rate is for intermittent MCAS failures.

It's clear Boeing didn't do any of this kind of testing because they would have easily caught the failure modes that caused the plane to nose-dive into the ground. Completely predictable based on the behavior of the system.

I agree that paper-medium has a huge advantage. If I had to find a word to describe it, it would be without a doubt Tangibility.

The usual argument, is that, people are just more used to paper, but while that's definitively true, it doesn't do justice to how bad screens are in comparison - for a certain subset of use-cases.
Paper is there. It's _very_ easy to interact with, with a _wide_ variety of tools for manipulation.

In relation to Netflix:
I've subscribed to Netflix, a year or two ago. I've subscribed to HBO, a couple of months ago.
Due to the increasing amount of streaming services, I'm now thinking of reverting back to P2P sharing (torrents) with a proper VPS setup (It's legal on my country of residence).
There are several reasons for this - none of those is pricing - which to be fair, is very okay for now - I pay less that 10$/month for both services - I'll probably have to spend more in a personal setup):

- Data freedom - i.e. no way of 1984 disappearing from my library)

- Privacy

- UI/UX-wise stable

- Functionally stable

- An open ecosystem, which means I can hack some tools for it.

I don't find it slow, though.
I wouldn’t be so quick to label “quick learning” as a good thing. Sure learning quick is good when you’re trying to adapt to new environments, but environments aren’t always changing. In edge cases quick learning in response to, say, a traumatic event and environment change, can yield learning that is maladaptive.

A suitable analogy is to look at gradient descent methods — which explicitly rely upon a “learning rate” parameter that controls how quickly the algorithm updates its global result as a result of local, immediate, information. Certain classes of problems do well with higher or lower learning rates — so it is very unspecified and unknown how something like this translates to human behavior
