Stuff like this really puts my work into perspective. It makes my hardest problems seem like trivialities compared to lifting a cruise ship out of the ocean.
Suppose a Mach 2.5 (850 m/s) missile aiming at you. You blind it 4km out (about the same distance as Phalanx can engage) (suppose its sea-skimming so coming right onto your side). It takes 4.7 seconds to impact you. A DDG-51 is 150 meters long. If it was aiming center of mass, you need to induce a 75 m change in relative position in 4.7 seconds to cause a miss. This can be accomplished by like 6.8m/s^2 acceleration. Ok, so thats like 0.7G, super won't work.

But say its subsonic (mach 0.9... so like 300 m/s). Now your talking like 13.3 seconds to impact, and now need like 0.85 m/s^2 acceleration to induce a clean miss. Ok cool, that has some utility.

Oh, and totally, its a stop gap. But it's still useful to learn things like... how do gimballed laser systems behave on a ship? What type of maintenance is required? What unexpected interference is induced?
And more often than not, it's a set of technologies used for processing data on many machines which could be processed faster on one.
Part of the problem is that the IPCC in most of the more conservative scenarios were assuming humanity acted on climate change and limited CO2e emissions or that their growth at least tapered off (they did for a while after the 2008 crises).

I can predict that if you save $1 every year that you'll have $10 in 10 years, but if you don't save that $1 then the prediction isn't wrong even though it doesn't reflect reality.
What data structures and algorithms book do you recommend (Java)?
Instead of just doing interview questions, I want first to do some easy problems at the end of chapters so I can get super familiar with the data structures & algorithms.

What do you recommend?

True, but his examples were not from the US, which is reasonable. The USA does cities very poorly. New York has been forced into some true urban functionality by being the biggest city in the US, but that doesn't mean it's a fine model.

The difficulty of auditing someone is totally dependent on the complexity of their tax return. If someone just adds up the numbers wrong and pays the wrong amount of tax, how hard is that to catch? Whereas if someone reports thousands of different stock transactions over a five-year period, and those don’t quite add up, that could easily be a more expensive audit than a thousand automated ones.
The scale of this is so hard to comprehend. Seeing the people standing on the dry-dock below the ship, its just mind-blowing to see how massive both of these things are.
I work like you. Usually paragraph by paragraph, sometimes sentence by sentence. I usually won't break a chain of thought before editing, but I'll usually go back over what I just wrote when I'm done.

It's not really real editing though. You don't catch everything because you're still in the writing mindset. Plenty of times i've just gone back and completely re-written whole sections during editing. I won't usually do that while writing something. Editing and writing are two somewhat different skillsets.

Editing requires a detachment you can't quite get while something's fresh. You need a bit of time away from something before you can go and do a full real edit. It helps you look at things more objectively. Re-reading a first draft of something I wrote after usually only a couple of hours kinda makes me cringe sometimes even with some inline editing while writing.

I look at it like coding. I'll write a section, test it, fix simple mistakes, keep going until I hit a bigger complete milestone, then go back and fix all the real mistakes while I'm debugging.

ETA: Sometimes I wish the edit windows were longer on hn. There's been a few comments on here I wish I could go back and change after i've had time to.look at them more objectively. Not always downvoted ones.
The ship they're lifting? It's pretty flat bottomed so they can just build a small cradle under the ship. There's also some tall yellow support (or maybe access to the interior?) structures on one side in the video.
If time is no object, you could do it yourself with a straw. The pumps only needs to be powerful to drain the ballast tanks quickly.
I have a strong feeling this is a hamfisted attempt to make stories or some other camera related feature more seamless.

But FB has kind of burned any goodwill anyone had for them, so I can't exactly be sympathetic if that's the case and they're getting skewered but didn't do anything nefarious.
AR technology development is really just about turning the crank, and Apple is best at that nowadays.
It doesn't need to be better, just different. Based on the test market, Amazon's offering would appear to address a very different segment from Dollar General, which often serves communities where the nearest Walmart is an hour away.

Amazon doesn't need to be cheaper than Dollar General, just the grocery section at CVS.

And yet your average engineer (barring oil and gas) in the marine industry will never earn as much as a software engineer.
The thing that gets me about that definition is that "too large to be processd in a single machine" leaves out a lot of variables. How's the machine specced? How's it being analyzed? Using what kinds of software?

If the only single-machine option you consider is Pandas, which doesn't do streaming well and is built on a platform that makes ad-hoc multiprocessing a chore, you'll hit the ceiling a lot faster than if you had done it in Java, which might in turn be hard to push as far as something like C# (largely comparable to Java, but some platform features make it easier to be frugal with memory and mind your cache lines) or, dare I say it, something native like ocaml or C++.

Alternatively, if you start right off with Spark, you won't be able to push even one node as far as if you hadn't, because Spark is designed from the ground up for running on a cluster, and therefore has a tendency to manage memory the same way a 22-year-old professional basketball player handles money. It makes scale-out something of a self-fulfilling prophecy.

Also, as someone who was doing distributed data processing pipelines well before Hadoop and friends came along, I'm not sure I can swallow "big data" being one and the same as "handling data that is too big to run on one computer." Big data sort of implies a certain culture of handling data at that scale, too.

Because of that, I tend to think of "big data" as describing a culture as much as it describes anything practical. It's a set (not the only set) of technologies for procesing data on multiple machines. Whether you actually need multiple machines to do the job seems to be less relevant than the marketing team at IBM (to pick an easy punching back) would have us believe.
This is due to the law. Flow rate through a shower is limited. There is no point having an adjustable rate if everybody wants more than a legal showerhead can provide.
> What they did is somewhat complex and involved obtaining leverage as much as the tax savings but basically they turned short-term capital gains into long-term gains.

That sounds like misdirection. It's very common for hedge funds to use tons of leverage. It's not like getting this level of leverage is an unsolved problem.

On the other hand reducing your tax rate from 37% to 20% increases your returns by 27%. Even that would be valuable, but the real number is probably even more than 27%.

Neanderthals had larger brain cases which suggests they had larger brains, though it's not understood why their brains would be larger -- what evolutionary advantage did it confer? Why wouldn't Homo Sapiens have a similar volume of brain case?

One speculative theory is that Neanderthals, with apparently better night vision and sense of smell (based on size of ocular orbits & nasal passages), had larger optic & olfactory centers in their brains. This seems a tenuous argument, however.

If brain size is directly proportional to number of neurons and neural links, then Neanderthal brains (and the larger brains of certain other mammals) would be more complex than ours, have more capacity, more memory, or other capabilities.

It's not clear why a mammoth or other elephant-like creature would have such large brain (the African elephant's brain is about 3 times as large as a human's). Perhaps there's some redundancy in the tissue, or legacy regions that are not used today.

Elephants are remarkably intelligent, and one can assume similarly the mammoths. Elephants have a sophisticated culture and have been observed to do a dance to welcome another elephant returned from a trip. They do have excellent memory; the saying "elephants never forget" seems to be true. They remember watering holes all over the savannah including ones that no longer exist on the surface, and they know to dig down and find the subterranean water in the exact spot that they hadn't been to for years. Social interaction is also important for brain development. So who knows? Maybe there's more to pachyderm intelligence than we are currently aware.
The pumps are probably pretty large just so it doesn’t take that long. It’s more of a large volume of water problem than a push it forcefully problem if that makes any sense. There’s something called hydraulic head or pump head that determines how high a pump can pump. It’s sort of a trade off between height it can pump and flow rate. The pumps used are more than likely centrifugal pumps rather than positive displacement.
As an aside on pumps, on the ship I work on, we have two fire pumps that are run off 11kV motors, they have to pump a large volume of water potentially pretty high for a deluge/sprinkler system. Our normal ballast pumps are 480v and when they come on the lights flicker but we don’t do much ballasting of the same type as the heavy lifts, it’s more for trim and heel.
There are also considerations that a partially filled tank can lead to instability (free surface effect) and they have a definite sequence that they must pump out the tanks to prevent excess stress on both the vessels (on ships the bending is called hogging and sagging). Some ships if they are loaded/ballasted in a certain configuration can actually potentially break in half.
> And before someone says that it's a scam, there's no outside investors in the Medallion fund anymore, so if it is a scam, they would only be scamming their own employees. And if that was the case, I think we would know.

There are other possibilities. For example shifting profitable trades that occurred in their external funds to their internal funds. In which case it is partly a 'scam' and they would not be scamming their own employees.
It's market failure because you'd have to find a way to basically compete with Facebook while your TAM/potential is 5x smaller.

I wonder what J.K. Rowling and any authors with really complicated plots would have to say about that. http://blog.paperblanks.com/2013/05/j-k-rowling-book-outline...

Not that I know how the mind of a great author works, but it seems that it would be difficult to write a great story without having some solid idea of what the final product should look like before you start. Like creating a product, maybe they pivot a lot after realizing that something doesn't work well (Margaret Atwood apparently did that for a book once, completely started from scratch after realizing that she had chosen the wrong point of view for the protagonist). BUT it's difficult for me to imagine they don't actually have a good solid idea of the story they want to tell before they start writing. If not book by book, then at least chapter by chapter. But hey, I'm not an author, maybe their minds really do work differently. It's possible.

I guess my overall point is that I don't think having a solid idea about what the final product should look like is the reason why authors have the "never edit while drafting" because I think they also pre-structure their ideas, and diverge on "editing while drafting" for some other reason. But of course I have no data or evidence to back this idea up.

Ah, you meant in the select, not the table. I guess I'm just much more in favour of being explicit, but I can understand the usefulness of what you said now that I fully understand it.
The image on the top is quite misleading: like an iceberg, 90% of the ship is underwater in that photo. The real thing is about as big as the cruise ship; watch the video to get an actual sense of how large it is.

One rock star earns a lot more than one orchestra member, too. Why? Well, the orchestra member is one of several dozen people. The rock star performs for the same audience, but concentrates his compensation by being one of maybe 5 people performing.

Similarly, the one software engineer produces a lot more per capita than the marine engineer does, by working on problems that don't require so many people.
I apologize, I remember the comment being longer. I also did not mean it as an attack against you specifically, more that the act itself is annoying (not necessarily that you had ill intent, it could entirely be coincidental).

Whataboutism isn’t a defense. OP was pointing out that, as an outsider, it’s obvious NYC is lame for the class of city it’s trying to be.

They need secret shoppers on Airbnb. I have friends that do corporate housing through Airbnb, VRBO, and CHBO. If these fake or misleading Airbnb stories stir up enough problems, local and state governments will severely limit or restrict these listings.

This section shows how Lighthouse calculates your overall Performance score: https://web.dev/performance-scoring/#lighthouse-6

(Note that the table gets cut off on narrow mobile screens... I’ll file a bug)

FCP is 20% of the score. The other metrics capture different milestones in the loading experience. For example Total Blocking Time is intended to bring awareness to sites that may look complete but can’t respond to user input (because the main thread is busy running JS).

The metrics overview that we just launched provides more detail about how our metrics were designed to capture the end-to-end loading experience (or at least that’s what we’re working towards): https://web.dev/user-centric-performance-metrics/

So in the case of your site-that-just-loads-a-spinner example, yes it might have a good FCP time, but it’s LCP time probably wouldn’t be that good, and therefore the overall Performance score would be mediocre.

Long story short, I don’t think it’s as easy to game a good Performance score as you might think

i think it's worth posting, though. i still find little things that blow me away (most recently: it has a screensaver), and afaik i don't think it's a widely-known website. i've always been kinda obsessed with the idea of making an OS-style website, but this killed the dream for me as i simply will never be able to come near this particular demonstration.

that being said... your project might be the thing that helps me reach whatever eureka! moment i need. i poked around the github a little and i'm already excited at the modular principle used - it makes the webpage-as-OS concept far less intimidating, seeing the various components broken down into their respective pieces. most of the code i've ever peeked at is always at an extremely polished level that makes it too nebulous for someone at my very modest level of experience to use as a concrete inspiration/example. thanks for sharing!
SAC Capital says hi
> nowhere else in the states comes close

SF comes close.

After moving to SF from [small city/town] Europe a few years ago I spent a long time thinking about what it is that draws me to SF and why the only other city in USA that I'd even consider is NYC.

The answer I came up with was population density combined with population size. You want a big dense population. That creates the economies of scale that make a city feel like a city.

For example I've got 2 corner stores, 3 bars, and 2 restaurants on the same block as my apartment building. That just wouldn't make sense if there wasn't enough people around here to support those businesses.

If you look at US cities by population density on Wikipedia you'll notice the only places with more than 100,000 people and a density above 10,000 per square mile are San Francisco and New York with some surrounding cities in the greater megalopolis.

https://en.wikipedia.org/wiki/List_of_United_States_cities_b...

Next on the list is Boston. Then Chicago, Philadelphia, and Miami. But those have densities in the low 1X,000/mi^2 whereas SF is at 17,000/mi^2 and NYC a whopping 27,000/mi^2.

Without density a city feels like a sprawling suburb.

I would argue that a lot of sports, partly based on the structure of rules and partly inherent to the sport itself, are biased toward some kind of body type -- assuming we're talking about elite competition, which is the context of the article.

And while some rules (such as those governing the size of a basketball or the height of a volleyball net) could be adjusted to include some groups, other groups will be likewise disadvantaged.

I would also argue that notwithstanding your values, there are probably different optimums to achieve between the peak pro level and the community and youth level, but unfortunately people worship pros so much that at some point they would likely feel insulted if they had to continue with metaphorically shorter basketball hoops.
That’s not possible. The chip used in that model was limited to 16GB. I worked in IT at that time and DB admins begging me to get them a 15” at that time with 32GB of RAM. I told them the chip from Intel was the limiting factor. When Apple updated a year or two ago, they moved to the next version of the chip which allowed 32GB. So yeah, 32GB in 2015 was not possible.
It would be nice to see a summary (if feasible) at a section level or a summary page listing key points across sections.

Though there are several resources for making websites better (and faster), it would be good to have a complementary set of pages with recommendations based on, and linked to, these findings (while keeping in mind that this research is on a large, but limited, dataset).

This looks... too good to be true. And indeed, I just tested it out on the quadratic formula, and the result doesn't seem to be terribly useful?

I checked out Hudson Yards as a tourist, and I would also agree it’s not a great example of a mall. Both the architecture and the shop selection seemed to be tuned more for Instagram-worthiness than for being a place you’d want to spend time, eat, or actually shop. The same goes for the mall in the Oculus.
