Arbitrary-precision integers are not that slow if they're implemented the way most Lisp implementations do it. For a strongly-typed language, you would need only one tag bit: if the low-order bit is 0, then the remaining bits of a pointer-sized word, shifted right 1 bit, are the value; no heap storage or indirection is required, and addition and subtraction require no fixup afterwards as long as there was no overflow. Only if the low-order bit of an operand is 1, or if there's overflow, do you have to trap out to the general case which handles heap allocation.

Yes, this is slower than ordinary fixed-width integer arithmetic, as a couple of conditional branches are required, but it's nowhere near the price of heap-allocating every integer.
Why not make auto-sizing the default and manual size control the exceptional case? It's already like this "in reality," I just wish the language would follow that.

I use templates so my editor shims in the above anyway, at the cost of lots of noise.

IBM has definitely created some cool stuff at various times. The problem, though, is that IBM misrepresents themselves in publicly-facing marketing and with paying clients during implementation.
At a guess because he didn't? If there is anything that would prove a crime he might hope submerging the boat would erase the evidence. It's all way too reminiscent of Hans Reiser trying to erase evidence of murder and pretending he was smarter than the investigators. That did not end well.
You can read a lot to support nearly any claim, that statement is less valuable evidence than even an actual anecdote. Regardless, surely you'd be able to recall at least one reputable source to serve your "explanation." Why do all the high performing organic search results supporting your claim come from sketchy websites and paranoid blogs? I see the "soy is evil" sentiment come up on hn with some regularity, and I can't understand why because the argument never presents it as more a credible claim than alternative medicines or homeopathy.

I don't really understand why this stuff is in the news so much these days. Boca burgers have been around forever and they taste fine - I tried Impossible Foods and it's at best a marginal improvement. And as for mayo, Vegennaise has been around for a while too and it's totally fine, other than getting a bit soupy when the jar is almost empty.

This is like saying people who are defending FB have some agenda where they don't like seeing criticism against it. For example, you could be someone who coaches freelancers who might hang out on HN and also be coaching them on using FB ads. Remember that when you point out that others may have agendas, there is always the issue that you could be subject to the very same suspicion.

In any case, the real issue isn't that Zuckerberg thought his users were "dumb fucks" when he was young. The issue is that he keeps acting as if he believes it, till today. Take the example of the WhatsApp acquisition. A lot of people, even here on HN, rooted for the WhatApp mantra of "no ads, ever". Now they have clearly been cheated. Interestingly, the usual response to those who complain about this spectacular bait and switch is - "it isn't FB's fault if WhatsApp users were 'too dumb' to trust the words of the company's founder". The lack of ethics amongst these founder types has somehow now become a burden to be borne by the "dumb fucks" who pay for these services with a lack of privacy.

Someone once asked here what is wrong with shadow profiles - that is, why are they actually illegal. The answer was prompt and quite clear - "because those who don't have accounts on FB but have shadow profiles have never explicitly agreed to the ToS". I think if anyone is willing to dig deeper into this issue, it will lead to the same conclusion at a much larger scale - there was nothing "legally wrong" going on, except a large mass of people acting like "dumb fucks" by say, not reading the ToS carefully. Hey, what do you know, supply people with mass quantities of undecipherable garbage called the ToS, and most people are too "dumb" to understand its implications. The assumption of dumbness amongst your users, it turns out, can take you very far - even towards trillion dollar valuations.

Recently, there was this story about the EU fine of 1% of turnover if FB was found guilty of misleading claims. "Those dumb fucks", Zuckerberg probably thought,"the price of providing misleading information is just 1% of the turnover? Who put these dumb fucks in charge?"

I would be very happy to supply more examples if you ask for it.
Not that I think it is worth near that much cause it is 99% speculators, but I would assume it is based on current market price * current BTC withstanding just like how stocks market cap is based (subbing BTC with shares).

I'm in rather strong agreement with your post. There seems to be some brand of, I don't know, utilitarianism? That decided that any life, no matter how wretched, is equal to any other life in the evaluation of how bad things are, when this just can't be correct.

This one, though, I would say comes from biology. Power imbalance is the name of the game of everything in nature. You can find it in monkeys, you can find it in simpler life forms.

At some point, we need to accept where all this garbage originally came from (which is also why it's so resilient and strong) and oppose it, assuming it won't eat us first.

This is getting very off topic, but I think that's a terrible basis for disregarding the ethical argument against eating meat. Why is it "species-ist" to think that mammals and other animals with highly developed nervous systems might have a conscious experience similar to our own (and not plants)?
It seems to me like more of this fragmentation will make streaming less like cable.

It looks like disintermediation, which is what the Internet was supposed to do. Direct from the studio to the consumer. But the reason probably comes from a bad deal.

One would think the NFL would run their own network. Major League Baseball does. But ESPN (owned by Disney) way overpaid for rights to show NFL games, for which viewership is declining. ESPN subscribers are down 13 million from the peak. They bought NFL rights near the top, so the NFL has a great deal for a few years. ESPN had to downsize substantially because of that mistake.[1]

On top of that, ESPN also apparently made a bad deal to broadcast NBA games. The phrase
"sports rights bubble" is used.

This activity at Disney may be trying to dig out of the ESPN hole.

I'm out of my depth but I found this interesting. Is it accurate?

"But Z2 is usually studied with first-order semantics, and in that context it is an effective theory of arithmetic subject to the incompleteness theorems. In particular, Z2 includes every axiom of PA, and it does include the second-order induction axiom, and it is still incomplete.

"Therefore, the well-known categoricity proof must not rely solely on the second-order induction axiom. It also relies on a change to an entirely different semantics, apart from the choice of axioms. It is only in the context of these special 'full' semantics that PA with the second-order induction axiom becomes categorical."

> This is a really bizarre assertion: my bubble is such that I've literally never met someone (that I'm aware of, just as with your claim) who _doesn't_ pay their credit cards off in full each month.

I'm probably halfway in between the working class and the tech bubble. In fact I grew up near the poverty line. I have a lot of lower class "technical debt" that I am still working to replace. Most recently my wife and were replacing the non-existent financial skills that my parents and public education system imparted to me. All of that to be said, it's no wonder we have polarized experiences with credit cards.

I did a quick Google search to make sure I wasn't completely off base here. According to the American Bankers Association Credit Card Market Monitor May 2016 report [http://www.aba.com/Press/Documents/ABA2016Q2CreditCardMonito...] 42.1% of Americans are Revolvers (carry a balance and pay interest) and 29.7% of Americans are Transactors who pay their bill in full each month.

I'm not insulted because we we're absolutely being irresponsible with our finances. We didn't have a budget to flow, we we're not saving money for future purchases, and we were very much not in control of where our money was going.

> But I don't justify my weakness by claiming that we'd be better of if dessert never existed[1].

I don't think I was suggesting that credit cards should never exist or that they are evil. I was trying to contrast the fact that even when 29.7% of people are benefiting from 1% - 4% cash back, that 42.1% are not. And that the companies who offer these products are in fact making money on them. Because people like me we're going into debt using them. And in my case, I was buying crap I didn't need and really shouldn't have bought because I truly couldn't afford it. Otherwise I would have always paid my balance in full at the end of the month.

For anyone interested in (or worried about) this I strongly suggest to read A Philosophy of Loneliness by Lars Svendsen.

This book analyzes loneliness (and solitude, the more positive counterpart) to a great detail, and offers some constructive and positive suggestions on how to transform the former into the latter.

The number is calculated by number of bitcoins in existence * price of bitcoin.

Same as the stock market.
Currency exchange rates affect businesses as well. It affects buying power between countries and can give companies in one country an advantage over companies in another country.
Bitcoin is capable of storing value because its features allow value to be exchanged. Of course that doesn't endow it with value. But we endow it with value because we inherently value a decentralized method for the exchange of value. Bitcoin's existence bootstraps its value.

>Why is it good that bitcoin is so inefficient?

It helps increase the confidence in bitcoin. We value the energy used to create bitcoins so that helps us recognize the value of the coins. It's no different than rare stones being valuable because of the work expended to find them.
That's negative land value. Doesn't bode well for investment though, but more of a depreciating luxury like a weekend car.
there's a tiny book called Godel's Proof that is both short and easy to read. I picked it up in my quest to read everything Hofstadter (he wrote the foreword) and thought it made it pretty straight forward. any axiomatic system that's flexible/powerful enough to make some sort of statement about itself will succumb to this method for constructing a paradox - and so all such systems are either inconsistent (paradox is possible) or incomplete (lacks sufficient flexibility to make a statement about itself).
> The real killer IMO is most young adults just don't watch much TV in any form.

It's interesting, I'm 32 so on the upper end of millennial. We're supposed to be the multitasking, multiple screen generation.

But I'll visit older relatives, say 55+, and they'll have the TV on constantly and just talk over it. I find it so distracting and honestly stressful, like when you're on a conference call, your boss is Slacking you and your friend's texting about their fight with their SO last night.

My friends my age all say the same. For most "young adults," you're either silently watching TV, or you're doing something else.

My best guess is that TV has gotten louder and faster paced, but older viewers have hung on to their habits. I bet I could easily have a conversation during Cheers or '90s Law and Order, but not today's shows.

A hard part of React is determining when and what to re-render. It's one of the main things the state-management tools solve (Redux, MobX, etc).

For example, imagine the naive example where you just have a global `const store = { ... }` and all components read from it and update it. You could tell everything to re-render on any change, but that's slow. So you can then implement `shouldComponentUpdate` for each component to manually check if their dependent data changed. But that may be a lot of work where each component needs to know quite a bit about the data.

For instance, how do you check if two arrays are the same and without walking both arrays? Depending on your data, it may be as simple as comparing `item.id` of the first item in each array. But it might not be.

On the other hand, you can tell if two immutable datastructures are equal with reference equality (obj1 === obj2). If all of your components take immutable data, then you can abstract away `shouldComponentUpdate` with a reference comparison. This is what React's PureComponent does.

That's the main use-case. Not as many obvious use-cases on the server side in Javascript.

> If not using/having credit cards is what works for your family, more power to you. But don't assume just because I use a CC for my purchases I'm in debt or foolish. In fact there's a whole subculture of making money off of credit card offers (see /r/churning).

I don't think people are foolish for having credit cards. And certainly hope that my comment didn't paint credit cards or cardholders as evil.

I think there people like me, who grew up thinking that having a credit card payment was just how things worked. And if you wanted to splurge on something you could just put it on the credit card and pay it all off come tax return time. (Trust me I know how ridiculous this sounds, but this is what I learned growing up. I still see my friends and family continuing this insanity).

This thread is about getting outside of the tech bubble. I consider myself to be blessed having grown up in a low income bubble, it was very humbling. I also consider myself even more blessed to be trending towards the tech bubble. These two bubbles are very different and I was trying to provide some context to that difference. Hopefully this helped provide a different perspective.
I really do think there is a pretty sise-able market at least in California for people looking to reduce their intake of meat but not wanting to go full vegan. People who like the taste of a good burger but want to be healthier (more fiber, less fat and less antibiotics) and reduce the environmental impacts. I am one of them.

I think one of the simplest solutions would be to have a different line of products under a different brand name which had a mixture of plant based meat alternative (i.e. Boca or Impossible Burger) to actual meat in the burger. That way you get the taste of meat but the substrate is fiber based.

The level of actual meat could be adjusted like they do fat content for ground beef (i.e. I'm feeling sorta vegan today so I'm gonna go 75% plant based today).

The one thing I never understood is American vegetarian restaurants who serve tofu steaks as the entire dish. This looks awful:

http://www.pbs.org/food/fresh-tastes/asian-baked-tofu/

Asian people always eat tofu blended in with a bunch of meat and vegetables for the actual flavor.
Here are some examples:

Of course they don't want what is best for us. They are an incorporated enterprise. Sergey and Larry may sometimes want to do things that make the world a better place, but at the end of the day, Google will do whatever is best for them, their founders, and their shareholders.

This concept that companies should be expected to act in the best interest of their users/consumers/employees is why some people have the misconception that all regulation is bad, and leaders are applauded for blindly repealing them.

Personally, I don't expect anything more of a corporate enterprise than that of which they are legally obliged.

Lisp under SBCL is as fast as Java under the latest Oracle JVM and for numeric computation is sometimes as fast as Fortran.

This means at least 10-20x faster than CPython, Ruby's MRI and others.

I routinely read third-party Lisp libraries and they are very readable, no problems with that.
