Also @dang, should require every user to add a tag/label that will show us if they are a Bitcoin speculator/owner, and would be great if then upvotes/downvotes had a stat that was viewable to see what % of upvotes/downvotes posts or comments have are by those who are financially incentivized for Bitcoin to succeed.

Edit to add: what are the odds this comment would be downvoted in a Bitcoin thread? Would be great to see the bias of upvote/downvoters and commenters in Bitcoin threads, then can have 2 thread columns: top comments for those who own Bitcoin, and top comments for those who don't own Bitcoin; obviously it'd an honour system and could be gamed.

Not making a judgement either way on BTC's success but what you've highlighted there isn't evidence. An artificially inflated market based on speculation would show the exact same signs.
A lot of comments here attacking this guy's name or things totally tangential to the meat of the post: simply plugging in some numbers into a financial formula to estimate the market's implied probability of these BTC exchanges going bust.

A lot of people here probably have BTC in their own wallets so don't care but the current btc exchanges (binance/coinbase etc) collapsing like mt. gox did would not be good for BTC in the short run at the very least.

On one hand I'm completely ok paying for a service like this, because it is worth it. On the other, I'm pretty angry about this change.

I am so sick of services luring you in with a free tier, then changing the terms once they have you locked in.

I've been considering a movie to 1Password for a while, and this is the final push I needed to jump to their paid tier instead.
It creates an Enumerator (for practical purposes consider it a continuation) over the method "each" unless you've passed in an argument named "block", which by convention would be a block argument (a closure passed after the argument list effectively) that will evaluate to Proc object.

Consider this example:

class Foo
def each
yield(42)
yield(:hello)
yield(:world)
end
end

You can now do:

Foo.new.to_enum(:each)

(In this case the ":each" is redundant - to_enum defaults to :each, so you could do Foo.new.to_enum)
And you will get back an Enumerator that supports the Enumerable interface, giving you methods like map, inject, to_a (to array) etc. as a facade to the original object so you can do (for example:

Foo.new.to_enum.to_a
=> [42, :hello, :world]

(you can achieve a similar thing by including Enumerable into the class in question, but to_enum lets you do this on arbitrary objects without messing around with the class)

It allows any method to return something that behaves like a collection class without needing to pass more than a method that implements "each" by yielding each value of the collection.

You can also do this with a bare lambda, btw., but the syntax is a bit awkward as "yield" is syntactic sugar over calling the "call" method over an implicit (unnamed) block argument that isn't quite as transparent as you might like:

ob = ->(&block) { block.call(42); block.call(:hello); block.call(:world) }.to_enum(:call)

The explicit "&block" argument is needed because "yield" has lexical scope where defined.
"ob" is now an enumerator that supporters each, to_a, map etc.:

ob.to_a
=> [42, :hello, :world]
I have been watching some BTC related companies recently and one caught my attention - Canaan. A few days ago they announced purchase orders of 100,000 mining machines for 2021. Supposedly many were pre-paid.

Also of note was their claim that in late 2020 they shifted their client base from individual miners to mostly publicly traded companies.

I am not sure what to make of it. Maybe HN can chip in?
As I watch the total crypto market cap shoot through the roof over the past year, one thing I've been wondering is what will stop a global "bank run" on the exchanges when/if something like this does happen?

I was reading thru Coinbase's own insurance wording, and it's clear they dance around it by saying:

To the extent these funds are held as USD in U.S. banks, they are maintained as pooled custodial accounts at one or more banks insured by the FDIC. These pooled custodial accounts have pass-through FDIC insurance up to the per-depositor coverage limit then in place [1]

Which basically means, only Coinbase's holding accounts are covered for $250k, not our personal accounts. I can't imagine the US Gov stepping in to rescue US crypto account holders when/if it does tank, but it might be necessary if it balloons enough.

On the flip side: whole projects are stuck on older versions so even though something like the walrus is interesting and could be useful no one else on the team has any interest in doing the work of switching to a newer version so none of the new features matter.

This is a bit hand wavy. Holding Bitcoin has real administrative and compliance costs for financial players in a position to sell Bitcoin futures. Particularly since, to do this properly, you’d need to be trading on the referenced cryptocurrency exchanges.

Also, I don’t think that default probability equation works for this case. (It’s also highly sensitive to the recovery assumption.)

I don't think this is the case, it feels more like people here are no longer as easily charmed by the whole buzzword catalogue surrounding bitcoin.

I have skimmed through the post series and some comments over here, like from the Singapore Chinese about non-startup business and Ronnie Cheng chinese love money comment https://www.youtube.com/watch?v=O_KpLrHCAx0

There are only two reasons why a business can succeed from Chinese point of view, I am writing this as a Malaysian, ethnicity is Chinese.

1. Work Hard (grit)

2. 会做人 (know how to take care of other people's feelings and needs first)

To elaborate on the second point, you have to know how to lobby and please

1. the government

2. the police

3. the other rich businessmen/women

4. the clients/customers

and of course those of famous people around the town you operate your business in, like

5. bad guys who are notorious

6. pretty/powerful people

if you are doing all of these, it is just bad luck that if your business fail, from Chinese point of view.

There are infinite reasons why a business will fail, and as a Chinese businessman, what you would do is to quit that industry and start in another one (grit).

> "Is your claim that the picture is the building?"

You said "a model which makes accurate predictions is as real as real gets". That the picture is the building is your claim here, that there's nothing more real than an accurate model, which I'm countering by absurdum. Wind can turn a turbine, a weather predicting model of wind cannot. You say "the differentiation [between a model and reality] is meaningless", I say a model is a leaky abstraction - when you send a single atom through a Young's double slit experiment and it interferes with itself and generates a wave interference pattern, that's leaking a reality outside the billiard-ball model of atoms, that's one time when the distinction between model and non-model is meaningful.

> "If that building is destroyed in a fire and remade to those exact specs, do we not say it is still a building?"

If the building is destroyed in the fire, and your model of it isn't, how can you say there is no difference between the building and the model?

Voyager-1 single dish detection at Allen Telescope Array
"Only if you fail to take the obvious step of looking for the external influence--and finding it in the case of the radio receiver, but not in the case of the brain." The neutrino was hypothesized back in the 1930s solely on the basis of missing mass/energy in beta decay. (One of the papers describing this was rejected by Nature on the grounds that it was too far from reality.) It was only decades later that the neutrino was found (in whatever sense a weakly interacting uncharged particle can be "found"). At any rate, I'm just saying that it's not illogical to hypothesize that the brain is more like a radio receiver than a tape player; whether it really is, is a different question.
Bitcoin in itself is quite useful, it’s something people will exchange for usd or things of value which the gov can’t censor or directly police.

Out enough, forever. That’s why if you ask me it makes logical sense to have 1-10% Of the portfolio betting long or short, because it has a much better than 1 in 10 chances of going x10 or -90% in relatively short timeframe. I didn’t backtest it but looking at a chart it looks like there are those many-sigma shifts every 2 years.

To that extent, if you’re interested in betting on it, you might want to use option contracts and make sure your max loss is fixed at the premium and the upside is unlimited.

I wouldn't be so sure.

Based on context, GP's example is a ManyToMany field. "friend_set" is what you'd get on a reverse ForeignKey or reverse ManyToMany by default, but can be changed with the "related_name" kwarg.

Either way you're right, GP's example as given doesn't have the 1+N problem (it's 1+1 at worst, a single query for user and a second single query for all friends), there's definitely missing context if they are seeing it.
Intelligence operations like the NSA, CIA, etc operate under a dual mandate: 1) gather information on foreign governments and 2) keep domestic information secure. However, with everyone using the same software, both mandates are in conflict. Any attempt to secure domestic information by fixing security holes also diminishes information-gathering capability elsewhere.

My personal opinion is that spymasters have decided as a class to leave things open in the name of keeping a job. Better to let China read your secrets than to lose access to China's.

Anecdotal but the gamification of exercise with respect to some of the newer products out there (Peloton, Zwift, Apple Fitness+) seems to be a step in this direction. I've been using Zwift for the past couple of months and have ridden my bike more than I have probably in the previous year combined. Most of it I don't really care/bother with, but when it keeps track of your records and you beat one during an exercise, it does give you a little of that dopamine rush.

Segment is a product that allows you to write events once and then allows you to send them to whatever tools you want.

If you use amplitude or Mixpanel you're locked in with an SDK and it's harder to switch vendors. With segment you can write events once and decide afterwards where to send them.

This is useful as your company grows and you start using analytics events in BI tools, Marketing tools (like Intercom) and product analytics tools (like Amplitude)

first, I don't understand how this quote squares with your overall description -- it's specific, first-hand, from a named source, who should (on its face) know what he is talking about:

> “This was espionage on the board itself,” said Mukul Kumar, who said he received one such warning during an unclassified briefing in 2015 when he was the chief security officer for Altera Corp., a chip designer in San Jose. “There was a chip on the board that was not supposed to be there that was calling home—not to Supermicro but to China.”

second, the article presents a plausible scenario for why it would be difficult to get additional details: the U.S. govt's strategy for dealing with this was to let it play out, so they could learn more about the nature of the threat. any public disclosures about this are at odds with the strategy of the U.S. government in combating it.

it seems like a very realistic scenario to me that some of the details of what happened became "lost in translation" - but that there is a real underlying truth. the first article wasn't convincing to me, but this one is very difficult to dismiss.
