> Segwit is all about sidechains, that's the main application, and the real purpose.

You're just wrong. Segwit is about a major malleability bug. It happens to open the way for sidechains, but do you honestly think we shouldn't fix the bug purely because it happens to make sidechains more feasible?

> Side chains mean transactions off chain. Transactions off chain mean less fees for Bitcoin miners. It's not rocket science.

Correct, but you don't seem to be following the problem the same way I am. Your major concern is how much miners get paid. My major concern is network adoption and decentralization. Pretending that your values are the only values is what makes your position distasteful.

> The reason nodes are expensive is because they are doing full historical validation which is almost completely useless and unnecessary. Minor changes to the Bitcoin block header would make that completely irrelevant. The nodes need all data ever argument is total junk.

You just literally dismissed how an open block chain works. If nodes don't have the entire history attacks become arbitrary.

> How much does it cost to open and close a channel on the main bitcoin blockchain at a 1 megabyte limit with millions of users? It's not a free thing, it's very expensive.

And guess whose in the best position to implement channels (and collect the fees associated with it)? miners.

> To say that won't result in centralization is ridiculous.

Less than would exist by big blocks.
Stack Overflow’s mishap with self-reported data – tabs-vs-spaces debacle
Seems to me GP is right:

The remaining miners make the same amount per day, until difficulty is adjusted, and then much more.

Consider this: one pool with 20% hash power. They only get every 5th block, i.e. 1 coinbase reward every 50 minutes.

Now all the other miners fall away. Now this pool will still take about 50 minutes to find a block, but it will get 100% of them, thus still being rewarded a block every 50 minutes.

However, 2 to 10 weeks later (depending when the last difficulty adjustment was) (or longer, if difficulty adjustment is capped), a block is found every 10 minutes again, and the pool gets 100% of them, thus 5 rewards in 50 minutes.

On the other hand, gp also said:
> Also as there would be the same amount of transactions and less blocks, the blocks would have more collected transaction fees -> bigger reward.

If I understand correctly, that the hypothetical 20% mining pool would immediately get 100% rather than 20% of all transaction fees when the other miners fall away.

However, AFAIK the coinbase (mining reward) dwarfs the transaction fees (for now), so that should not be that relevant.
not sure if this is what you are looking for but I had success with this Java library http://aparapi.com/, it looks at function's JVM byte code and runs it on GPU if it can, otherwise falls back to CPU. I suspect same thing can be done in other languages.

https://github.com/Syncleus/aparapi/

"Aparapi allows developers to write native Java code capable of being executed directly on a graphics card GPU by converting Java byte code to an OpenCL kernel dynamically at runtime. Because it is backed by OpenCL Aparapi is compatible with all OpenCL compatible Graphics Cards."

According to the ProPublica podcast[1] (published this past week, so probably the catalyst for this 2015 article on HN), The World Bank was collecting data for decades on displacements, but wasn't consuming it for anything useful. The ICIJ + ProPublica FOIAed the data and painstakingly assembled it.

As I note conspicuously, the idea is not new. The Plan 9 OS 9P protocol dates even earlier, to at least 1992:

Actually there are quite a few researchers working on applying newer NN research to systems that incorporate sensorimotor input, experience, etc. and more generally, some of them are combining an AGI approach with those new NN techniques. And there has been research coming out with different types of NNs and ways to address problems like overfitting or slow learning/requiring huge datasets, etc. When he says something about abstraction and reasoning, yes that is important but it seems like something NNish may be a necessary part of that because the logical/symbolic approaches to things like reasoning have previously mainly been proven inadequate for real-world complexity and generally the expectations we have for these systems.

Search for things like "Towards Deep Developmental Learning" or "Overcoming catastrophic forgetting in neural networks" or "Feynman Universal Dynamical" or "Wang Emotional NARS". No one seems to have put together everything or totally solved all of the problems but there are lots of exciting developments in the direction of animal/human-like intelligence, with advanced NNs seeming to be an important part (although not necessarily in their most common form, or the only possible approach).

Go sit in on a meeting in Mountain View or Cupertino. Existing home owners don't want it and the elected admins don't want it. They are happy to foist the problem off on, well, just about anywhere else. They want wealthy folks in detached single-family homes, and the fact that they host companies that employ more people than can live there means constant upward pressure on home prices and the tax base.

In other words, it is an externality just like pollution that the producers don't want to internalize.

I just want to point out that the "Cost of a Hot Economy" headline is baloney - or rather it's part of the story but the least important part of the story, used as a cover for the more important processes at work.

Whatever the unemployment rate, the present level of "economic growth" is very much a product of a lot of money being pumped into the "real economy" and large portion of this money leaking out into investments like houses that are perceived as more solid and reliable than companies engaged in production [1].

The old effect of printing was a consumption-goods price spiral but the new, more hidden effect is capital-good price spiral (housing bubbles etc). But, of course, if wages aren't increasing and costs of living are, a little bit of increase goes a long to making people's lives unlivable.

And it's worth noting that rent-increases are happening in a wide variety of town in the US. Everywhere they're attributed to local factors and that further muddies the wasters concerning the root cause.

You're playing semantics. mortal/life-threatening risk/safety is clearly different from other forms of usages of the same word(s).

You absolutely should teach your children to avoid those kinds of risks, or at least, in the context of having dependants.

With a salary of $180K you can definitely afford to buy near SF. Banks will sign off on an $900,000 mortgage no problem on that salary. You have to put maybe $100-200K down payment for your million dollar 2BR.

Guess what? You need to save for a few years to get that, which is easy when you're making $15K pre tax a month and living in Manteca.

Only if you think the need of any society to be able to defend itself is an economic problem.

That depends on what threats we expect to have to deal with.

Also, if you argue that people with children should not be soldiers, you are taking out of the decision loop people who are likely to have a more restrained view of when violence should be used.

The diet that truly works is high protein. Carbs and Fats cannot convert to muscle like proteins can and as a result they can not raise your resting metabolic rate like proteins can. Furthermore proteins have a filling effect that satiates hunger and they are not easily stored as fat. If you focus on filling your daily allotment of proteins first, you will often find you are too full to fill the remaining Fats/Carbs requirement. This advice from a personal trainer helped me lose 60 lbs over a year.

Who do you mean by "you", when you say "you should"? Do you mean you as in YOU? Or everyone else? Of course people who can't afford housing want cheaper housing. But people who have housing don't want high-rise buildings in their neighborhoods and that's understandable. The solution is not to build more housing. The solution is to create work in other places, too. Why should all companies be in SF? Force companies to move to states with plenty of space.
you need to spend more money on your house then.
One of the problems is that the average size of a new single family home has been increasing for decades:

http://eyeonhousing.org/2014/01/average-size-of-new-single-f...

According to data from the Census the Quarterly Starts and Completions by Purpose and Design survey, the average and median size of single-family homes that began construction rose during 2013. For the third quarter alone, the average single-family square footage increased from 2,646 to 2,701, while the median rose from 2,446 to 2,491.

In the 1950s, average size of a new home was less than half that, at around 1200 sq ft. It also held, on average, more people.

I strongly suspect this is partly driven by tax incentives that are aimed at upper class families and help create or fuel a growing divide between the Have and Have Nots.

I've said it before in other threads, but I highly recommend The Color of Law by Richard Rothstein for anyone interested in this topic.

Much of today's housing crisis is a direct result of blatantly racist policies that were implemented to keep out PoC out of white neighborhoods.

Ordinances like minimum lot sizes, heigh restrictions etc. are the very same tools used by NIMBYs to keep new developments out of their neighborhoods, and choking the US economy.
That's not a good program... but it's better than nothing.

Depends on childcare costs, but probably. My budget for SF requires about $150k and includes unusually high retirement savings.

Personally, I believe that is an artifact of zoning laws + commute distance.

Most people I know rationally choose housing based on commute distance for an individual/couple + price.

My guess is that voters who actually care about city level politics or influential people in the city are already home owners. For home owners, building more housing means a decrease in their home value so they have no incentive to push more housing.
How about taxing 2nd, 3rd, Nth properties, unoccupied properties and foreign investors? Right, the "T"-word...
> Get rid of that though, and suddenly there's no economic incentive to own property.

How do you figure that? What about cost stability? What about not losing 100% of your payment (that is, retaining some as equity)?

I'm not saying there is always an incentive; some markets favor renting over buying in spite of the MITD. However, saying the only reason buying is financially attractive makes no sense.

Edit: corrected C (credit) to D (deduction), since it is technically correct and makes a big difference in it's usefulness.
This is still anecdotical, but most python developers I know would chose py2 if given the choice. It's what they know, and they don't want to change semantics even if it's just changing how you write prints.
That doesn't sound right. How many cave-going dads are there that you could make the claim? And do a majority of kids believe their fathers are boring? I just don't buy it. And is taking a risk like this the best way to be "not boring?" Definitely don't buy it.

You can have fun and be adventurous without taking heavy risks. It's fair to say that someone who continues to put himself at harm is foolish in one capacity or another.

If there were no zoning regulations, you are absolutely right...and this would've resolved itself long ago. But there are strong zoning and property rights at play. I'm very libertarian, and was priced out of the Bay Area (recently left grad school for Texas), but I'm actually sympathetic to the homeowners there who are using democratic means (i.e. their elected city reps) to support their interests. Society (in the form of the state government) could upend the property rights they are leveraging...but that would have significant incentive repercussions down the line. It would greatly weaken property rights...which is a foundation of Western society. There are far deeper, and interesting, issues aside from mere housing stock.
Or other parts of California with plenty of space such as the Central Valley. Unfortunately, similar to how homeowners don't want high-rise buildings in their neighborhood, companies do not want to build additional campuses or allow remote work.
People who beg for help, but are beyond help, are one thing. Yes, that's annoying, but you are projecting an awful lot that's not actually in this article.

I would humbly suggest that there is something deeper being triggered in your psyche that you would gain more by exploring than trying to convince everyone else how irrational this approach is.
Zoning laws aren't handed out by God on stone tablets. If current zoning laws prohibit the apartment buildings the cities need, the cities can and should change the zoning laws.
No. We added code that, if the power was too far off from what we asked for, tried to kill power three different ways, plus alerted the operator. It was a bit tricky, because the power is never exactly what you ask for (variable impedance match, plus noise).

Have you purchased housing in any of the more desirable areas of California recently? If you have, please tell me where this fantasy of your played out and I will buy there.

What happens to someone with a $100K-200K down payment and a bank willing to cover another $900K on top of that is that they put in a $1.1M offer with the required bank contingencies and then someone puts in a $1.1M offer with no contingencies and the cash offer wins.

Having a bank willing to lend you money has not been sufficient to purchase a home in most areas since the housing collapse because there's so much speculation in cash.

rental rates are exactly the same thing as interest rates (+/- wear and tear and so forth). what you retain in equity, you would equally retain by simply not paying into some other investment. There's nothing special about owning your home, there's no arbitrage to be had beyond the MITC.
For the analogy to hold, it's more of a question of whether or not ML algorithms operate in the same way as the brain. Right now, ML models use algorithms from continuous optimization that require certain structure. Namely, we require a Hilbert space, so that we can define things like derivatives and gradients. This puts certain requirements on the kinds of functions that we can minimize and the kinds of spaces that we can work with. These are requirements that are difficult to have precise analogies in biology. What does it mean to have an inner product in the brain? We does twice continuously differentiable mean in the context of a neuron? Even if there is a minimization principle, which I am not sure there is or is not, if ML uses algorithms, which are fundamentally not realizable in biology, how can we say it replicates the brain?
That makes sense. However from what I've read, the timeline is "SegWit -> multi-month transition period -> 2x HF".

So by the time the 2x fork comes up, the segwit-enabled chain will already be in use for several months.

Another point I'm wondering (sorry if that's a noob question) : Assume that some of the forks actually lead to a chain split with hashpower distributed 90%/10%.

At some point, the difficulty of the chains will adjust to bring both of them back to the "one block every 10 minutes" rate. However, this will not happen immediately but only when the current difficulty period would complete. Before that happens, the minority chain will still have the difficulty from before the split - the one that assumes 10x as much hash power as now is actually available. That sounds as if the minority chain could become effectively unminable for the rest of the difficulty period. Worse, as the period durations are measured in mined blocks, if blocks are mined slower, the difficulty period will also go on for a longer time.

Does that make any sense?

The arguments about Segwit are not about security holes. Segwit would enable off-chain transactions using systems that are patented and centralized, allowing others to control things on top of the bitcoin network. LTC isn't used for purchases, so Segwit hasn't had much of an effect there.
