> When I've implemented Hash Tables in JavaScript in the past, I've also included functionality to rehash the entire table into a larger array as it gets more than 25-50% full... but can't remember off the top of my head what's the mathematically optimal point to rehash.

The load factor (entries/bucket before you resize) varies greatly depending on the hashmap's addressing and collision resolution. Robin-hood hashing allows ridiculously high open-addressing load factors for instance (above 0.9 on an open-addressing linear-probed map, an open-addressing hash table can't go beyond 1), meanwhile separate-chaining allows load factors way above 1 (buckets are sequences and conflicting entries are appended to the sequence)
I agree with this. I would be ADHD if my parents sent me to school and/or believed in those diagnoses. I have yet to meet a gifted child male that does not qualify as ADHD. It is interesting to hear what you have mastered vs. struggled with. I can't say that my anecdotal evidence suggests that people always get a net benefit, just that in the right environment, people with autism can have complete, fulfilling and engaging lives. Unfortunately it seems to take a lot of will power and brute force intelligence to make it so, and not everyone is successful.

This isn't a counter point, all you're doing is proving my point. The consumer is the person who's being an idiot here, not the manufacturer. You can buy bathroom stall doors without a gap.

holy run on sentence batman

Speaking of commission, it "has to" be a fund because the SP500 is not constant, companies are continually being added and removed. Otherwise you'd directly owe substantial commissions and you'd have to be careful to avoid various capital gains income taxes while endlessly rebalancing.

There are a lot of index funds, for no apparent reason the first one I checked was VFINX and it's annual expense ratio is 0.17% which is pretty low compared to the average return over the past 90 years around 10%.

So the actual result would be a little lower, although not staggeringly so.
yes. We will have Daredevil!
You could just do it in lump sums twice a year or similar. Plus unmanaged funds like indexes have lower recurring fees than managed funds.

If I have my phone in hand and it was already open to a number dial pad then maybe it's easier to press 1,2,3. But often, even when I"m already in call, I have to (1) press a side button to turn screen on, then (2) look to find button to press to bring up dial pad, before (3) I look to press 1,2,3. I hardly think saying "customer support" (without diverting my eyes or attention) instead is "way too much effort" in comparison. In fact, I just used similar voice command in automated call ten minutes ago because it felt like _less_ effort than bringing up the dial pad. With home automation I expect it would be even stronger in favor of voice interface, because I would almost never have a phone in hand with home automation app in foreground with display on.
Thanks a lot for the courage to openly write that, it really means a lot to me. My posts have definitely hit the 'deserved justice' nerve of a lot of readers. I hope your answers don't get the same treatment.
"Having money does not make a good parent"

I couldn't agree more. In fact, I grew up in an extremely poor family, and my mother is an excellent mother!

But I also know how difficult it can be for a poor, single parent.

My point was that those who would choose to pay for their children to attend a Montessori school are a self selecting group, and I am not confident that if you took an average public school and turned it into a Montessori school that it would work as well as your private school. (It might very well work better than an average public school, though.)
Prescribing opium ... a trend that have not been seen in the world since victorian era in the UK.

Opium having the reputation to make people amorph losing their will to rebel.

The new trend is opioid are now cheap and not prescribed to the rich but the poor.

Religion used to the opium of the people they said, and now that opium is cheap, religion is not needed anymore to make people servile.

I love this new era of progress.

Tomorrow we make an application to help parents poor sell their kids body part on the internet for the cure of richer people?

I mean, let's try to make even more dystopic. We can do better. That is what progress is. Making system more efficient.
How do they handle DoS?
Where I live, Montessori ends at Kindergarten, unfortunately. I have three kids in Montessori pre-K right now, and it costs more than the mortgage on my house. But as other commenters have said, it's worth every penny. Kids are calm, happy, and engaged. They love school and learning. I'm not looking forward to public primary school, which is our only realistic option.
Bill Gates recreates high school photo for his AMA identity verification
I used Buzz a lot with myself and family. I think one of the points that made it fail the most was simply that it was set up to fail and not given the love it needs.

The problem is that the stock market is a sort of "inefficiency": Companies would prefer to keep their own profits instead of giving them away to investors.

Yes, people have done well in the past, but I believe it's entirely possible for median market gains to disappear in the near future as this inefficiency is removed: We're seeing the start of this right now, in the way many of the more desirable "unicorns" are relying mainly on private equity and loans.
THE E-PI-COMPUTER
I'm not sure I understand your question in that case. I do mean the kiosk itself.

You might have multiple Raspberry Pis (one for each screen) and then they just connect to tellybox.me to provide them with their slides.

I really like that in "Teiresias", if you make the canvas narrow enough, the man jumping (presumably Teiresias) changes position and gets a white beard instead of white long hair. Just to still give the impression that it's an old sage, in small vertical space.
I've been spending some of my spare time learning it. Just seeing the same thing working on my Android phone and my iPod Touch with almost zero code difference has been a beautiful thing to behold.

But coming from native iOS development, some things seem harder to grok and slower to implement (like I'm writing more code than I'd have to on iOS, and loading and saving data is the current thing I'm trying to figure out and it seems a little unintuitive, and like there's seven different possible solutions various people have made and are all claiming is the best). But I'm slowly working through that, and for me the cross-platform aspect of things really makes up for it.
You can't even imagine the pain and suffering the constraints currently in place cause legitimate users of pain killers. Doctors are so scared of the DEA they're doing crazy things. Someone very close to me had a ruptured disc, killing the nerves in her spine, so much that just standing would cause pain that made her black out or vomit. And even though she'd never been prescribed anything for pain, she had to hover over a urinal crying uncontrollably, to take a drug test to make sure she wasn't an addict.

If the line is between people suffering horrendous incomprehensible pain and people making a choice to abuse drugs. Well I'm pushing that line right up against the people who get the luxury of making a choice.
Huh. I always thought those parenthesized numbers after unix commands were version numbers.
There's certainly more than just scaling involved, but there's definitely scaling in there.
> (even though "computation per energy" is clearly a human win)

Is it? The problem here is it is really hard to compare the TCO. For example prime human computation requires years and years of learning and teaching, in which the human cannot be turned off (this kills the human). A computer can save its state and go in a low or even a zero power mode.

>such as clock speed (hertz) and memory size (bytes).

Which are completely meaningless, especially in distributed hybrid systems. Clock speed is like saying you can run at 10 miles per hour, but it doesn't define how much you can carry. GPUs run a far slower clock speed than CPUs, but they are massively parallel and are much faster than CPUs on distributed workloads. Having lots of memory is important, but not all memory is equal and hierarchy is even more important. Computer memory is (hopefully) bit perfect and a massive amount of power is spent keeping it that way. That is nice when it comes to remembering exactly how much money you have in the bank. Human memory is wonderful and terrible at the same time. There is no 'truth' in human memory, only repetition. A computer can take a picture and then make a hash of the image, both of which can be documented and verified. A human can recall a memory, but the act of recalling that memory changes it, and the parts we don't remember so well are influenced by our current state. It is this 'inaccuracy' that helps us use so little power for the amount of thinking we do.
iFlix gets $45m funding in battle against Netflix
This is why all the retirement advice is to regularly contribute - Smaller amounts monthly (or even more frequently) works way better than only doing so when you're flush. The key to this is not spending all the dollars you make on your present lifestyle, but setting aside some percentage for investment from every paycheck. This means you'll be buying in the down times too, where everything is on sale.

Of course it also means accepting a lower spending rate in one's life.
From what it looks, no. And yes, that's a critical factor.
Most web pages have suboptimal designs and dependency downloads. This system speeds things up by changing the order of dependencies such that the pages can be rendered more quickly.

If you do it manually, you can generally do things that will speed things up more significantly, but that requires time, specialized knowledge, and attention to a not very glamorous area of web development.

An example might be an image that shows up on a hidden tab that does not have enough information in the html for the browser to understand it is not a required element for initial rendering. If the request for that image can be pushed to the time frame after the initial render the end user has a better experience.

When the web was limited to 28K speeds for a significant amount of the userbase people paid a lot more attention to these kinds of things. Now that a significant amount of end users have broadband speeds, web developers are more concerned about other things because some things as simple as leveraging a CDN and outputting appropriate cache control headers are enough optimization to provide adequate performance.

It's not clear on my initial read if this is a new rendering engine, a client side script, or a server side parser that re-shapes output, but the intention is obvious - download things in the right order to get the fastest page load times. I've done this kind of optimization before and it can make an enormous difference - especially with bandwidth challenged end users.
Wow, epic!
What are the reasons for Netflix choosing nodejs for their front-end server and not java like in their back-end?
There was one for powerpcs (PSIM?) that IBM put out during the mac/power days.

But generally you run benchmarks to figure out what the costs are and performance counters to see how often your code is paying those costs.
Hmm. I partly agree, but "a sociopath"? That seems a bit much...
I like your communication here. I would love to explore this in a separate discussion at first glance I would say certain crimes are not possible at magnitude without a computer or technology to assist. With extreme simplification I consider computers to be a tool to increase productivity. With that said, I will agree, the same exact crime in type and magnitude should have the same punishment, not altered.
This is helpful but you're not mentioning what instance type at EC2.. t2 and t1 instances do heavy throttling after you use up your CPU credits[1] so it's likely that you were just using all or most of a full Xeon CPU. I got similar results on even a t2.nano.. until I used up the CPU credits. Then it slowed to a crawl!

Also keep in mind that nbench only tests a single CPU[2].

Apples to apples would probably be a small m3 or m4 against a comparable DO instance. (but let's not go down that cost disparity rabbit hole.. esp EBS vs SSD or bandwidth!)

honestly I don't know why you'd ever do a move or expansion to SF. The rise in expenses would kill you. Starting things there certainly has a lot of benefits, but moving anything more that a handful of founders after you get going would be a very rough transition.

With the cost and ease of flights to SF you can get a lot of the benefit of your business being there if your founders and fundraisers are ready to fly out and hustle.

> take their "storage snapshot", and turn off the server

Or rather, turn off the server and then take the storage snapshot, which is the order you have to do it. And you have to snapshot and reincarnate just in order to attach or detach a volume, which means adding some more storage space requires several hours downtime, which is a nuisance.

Although apart from that, I have found them very good.

What are the rates like compared to other countries?

Does the US just over prescribe painkillers, meaning more flood to the blackmarket?

Is it people are getting it from the Dr and accidentally ODing?

Are the Drs prescribing without care, so those who want the drug for a high and no medical reason can?

I never knew painkillers to be used as party drug / fun drug in the UK (outside of the heroin using demographic) nor ever heard of some one ODing on prescribed painkillers.

Seems strange it is such a big issue in the US
> Sometimes, maybe. I'd argue rarely. I don't see much difference between an unmanned drone and an unmanned satellite or a manned helicopter in terms of applicable law.

I think the important distinction is police vs millitary, not drone vs satellite vs helicopter. As @protomyth pointed out, there is existing law (Posse Comitatus Act) which may prohibit such things. The article does say that the drone flights were done in accordance with existing laws. But, given the propensity for the FBI to flaunt laws and mislead the public about doing so, I'm not sure how much I trust that statement in the article.

> Believing that a new law is needed because computers/drones/robots/AI/whatever now exist can lead to bad laws, or laws that are out-of-balance in terms of punishment. (i.e., commit a crime - 5 years. commit the same crime WITH A COMPUTER - 10 years)

I agree with this. I don't think new laws should necessarily be specifically created for this. At any rate, it seems like the Posse Comitatus Act should cover this already.

Check out the inside of the system... It works. It's only had about 10hrs of development from idea to today so I hope to improve things over the coming days.
Speaking from experience, the code is normally functional but unsightly, thus it would be embarrassing to place it online. Most researchers are happy to email you the code if you ask for it though.

Most of my code is for scientific computing and consists of a bunch of one-off Jupyter notebooks and Julia scripts that are written with two objectives in mind: get-the-task-done-before-my-advisor-meeting and make-it-as-fast-as-possible. Good coding practices and code cleanliness are not priorities. And particularly for code that needs to run on HPC clusters or supercomputers, it's really hard to make it look nice — one could easily spend weeks designing a proper, modular system only to throw it all away in favor of using a better algorithm that was just published. Anecdotally, the vast majority of my code has produced results that were later discarded.

For example, I have a function named YPXt. What does such a woefully named subroutine do? It multiplies a matrix Y by a permutation matrix P, and then multiplies that by another (transposed) matrix X. The matrices are small, so the overhead of using BLAS for the task is wasteful. It's better to use Julia's macro system to generate the necessary for loops on the fly and let the compiler SIMD-ify the result. Also, permutation matrix multiplies can be done in a way that doesn't actually involve creating a full permutation matrix. And of course the subroutine has side effects — in order to conserve memory I need to overwrite the input matrices instead of allocating new ones. Immutable data structures may work great for functional programming, but the overhead of red-black trees and stateless programming is too high for numerical data crunching.

Add that to the fact that a lot of scientists in academia are unfamiliar with tools like Git, and so manually versioning the code and emailing it back and forth is unfortunately a necessary part of the collaboration process.
Investment fees were high more than 25 years ago. I remember paying 3% to buy or sell a stock in the 1980s when you had to use brokers. That limited the kind of day trading strategies you could use. Its as little as a hundredth of a percent now for a large computer executed transaction.

This is what you wrote:

"The country of these assassins was invaded (without provocation) by Austria just before the assassination"

I don't know what "just before" means to you, but I don't think "5 years earlier" when I read that. If you mean the troop maneuvers just before the Archduke's visit, it's odd to say Bosnia was "invaded" by simply moving troops in annexed territory, 5 years after it was annexed.

It's just an unnecessarily misleading sentence. Note that I'm not diminishing Princip's or the Black Hand or Serbian nationalists' motives.
