> To me, the first rule of rewarding someone is to make sure the recipient did all of the work before the reward. If you make them work afterward then it sours the desserts.

For executives and directors, I disagree completely. The shareholders are paying them to make and execute decisions that will grow the company (and share price) over a long period of time. The share-based compensation plan should reflect (and help align) that they are being paid to make long-term decisions.

Those are inherently "promise/award before the hard work is done" type of grants as I see it. (Why would I pay you more for a decision you've already made or work you already did, unless we're just talking about a modest spot bonus for a job well done?)
Not directly, but Parity multi-signagure wallets on Ethereum Classic, Expanse, Musicoin, and other public chains are affected as well.
This begs the question: couldn't the Chinese government intentionally delay even small (outgoing) blocks to give Chinese miners an advantage (with either benign or malicious motives)?
I feel you. The time spent discovering a new domain is high-value but also very creatively demanding. Often underestimated by technical folk used to "coding to specification".

That stressful period, full of uncertainty and half-articulated thoughts, as you figure out the basic concepts, how they inter-relate, form goals, make things fall into place conceptually.

Personally, I don't find staring at a blinking cursor helps. During this phase, long walks work the best for me.
The libertarian counter argument to this is that public servants/bureaucrats shouldn't be in the business of investing trillions of dollars. The market gets to decide which investments get made and the investor takes the fall for bad decision instead of sucking on taxpayer's teats for a bailout.

I think it's somewhat amusing that I grew up with my single mother making less than the cited poverty threshold for one person, but still had a pretty good life without ever being short of money. She's been putting quite a lot aside for her retirement, too. I guess that goes to show how expectations can differ.
That's classy, trying to hijack the top comment to spread lies, ad hominems and smears.

>For example, he claimed in the announcement(1) for his Teechan payment channel scheme that it could do 2480 transactions per second, but neglected to mention that it achieved that by failing to actually write those transactions to disk and storing them in RAM only.

First of all, our actual deployments showed that Teechan can do more than 30,000 tx/sec across the Atlantic, in fully fault tolerant mode.

Second, the Teechan paper made clear exactly how we reported the initial, unoptimized numbers, which is precisely why you're here writing these bogus critiques.

>Emin's announcement and paper also gave the impression that payment channels weren't currently possible to implement on Bitcoin without segwit

We learned after publication that there are rumors of a "Lightning Network" implementation without Segwit. Unless you can point to a protocol specification, however, these remain unbacked and uncharacterized assertions, of the kind "I believe I can fly."

>Then there's how Emin's PR around that announcement presented Teechan as something that could be implemented right away as a replacement for segwit via Intel SGX, without mentioning that Intel required SGX users to get licenses to use it in production, and Teechan didn't have one.

This is HN, and I usually try to be more diplomatic, but this is stupid. First, Teechan is a protocol, it isn't tied to SGX. We are working with HSM vendors to deploy it on non-Intel hardware. Second, Teechan does NOT require the users to obtain licenses, it just needs to be signed by an entity. Third, Peter Todd has no idea about the nature and scope of academic work and how it differs from industrial deployments, which explains why he feels so threatened as to indulge in personal smears.

I could go on, but tearing down a known Bitcoin troll is pointless.

There's feeling like you're getting things done because you're on a coding roll, and then there's feeling like you're getting very little done because you're still organising the project in your mind.

I don't think the two can be separated. Being stuck and being moving are dependent on each other.

A lot of the time I'm frustrated because I haven't quite figured out how the code should look. It takes a long time, a lot of chopping and changing, before you come upon a structure that you feel comfortable building on.

When you do get to that point though, it feels easy. Everything you write makes sense in terms of your new structure, and there aren't so many awkward kludges. The only thing is this period can be brief, because when you're fast, you get to the next problem sooner. You'll find higher and higher levels at which to view your code, and at each level you'll need to do some organising.
What is the right term then?
> Real actions are already underground, extremism only uses public places to recruit masses to get better selection and financial support.

And it's exactly these public places where their ideas need to be opposed. If you drive them, and their ideas, deeper into the underground there will be no one there to oppose any of their ideas, it will be yet another echo-chamber driven by a victim complex.

> I bet you're living in first-world country saying that you we should just go and rationally talk to extremists.

What else you want to do with them through the Internet? Would you rather censor them and their ideas away like they don't exist, exactly like they try to censor opposing views away in their territories of influence?

How does that make us any better than them? It doesn't, it's hypocrisy at it's finest and exactly the kind of hypocrisy which also drives recruitment.

It's a giant crying shame on our "western culture" which supposedly values "freedom" so much.
He mentions fridge/freezer - I'll just draw attention to this project[0] where the smart guy uses a chest freezer as a fridge with an external thermostat. It has better insulation and design (cool air stays in when open), so ends up much more efficient and can be run on minimal power. Just 90 seconds of run time per hour.

There are other ways to do this in mobile setups, or with inverters in any setup, using mini-freezers, simple electronics to turn the inverter on/off and a small panel. See /r/vandwellers[1].

I've been using a Samsung 40" 4k TV as my main monitor for development work for about 8 months and it's been great for me.

A couple caveats -- Because I don't game or do graphics work, I don't know or care about color reproduction. I made sure to get a TV, graphics card, and cable that supported 4k@60hz with 4:4:4 chroma so the text is perfectly sharp and the refresh is not obtrusive. It's not hard to find a Samsung TV around $350 that supports that, but as far as I could tell, I had to go up to a GTX1050 graphics card to get that. I sit between 24 and 28" away from the monitor so the text is readable to me at full resolution. At that distance, I do have to turn my head to comfortably read text in the corners of the TV, especially the upper corners. In practice, that means I keep monitoring-type applications such as CPU charts, Datadog graphs, etc., in one of those corners for quick reference. While I still have two 1920x1080 monitors on either side of the TV, it's quite nice to be able to open up on my main monitor a huge IDE window and, when necessary, put 3-4 normal-sized windows next to each other for comparison work.
Cherry picking a controversy doesn't do much to generalize an entire field (if you want I can find some Freud controversies and say that psychology is hocus pocus). By the way, I'm not american.
Funny enough, that one you picked is exactly the opposite from here. The authors were harshly criticized for NOT applying "mathy" rigor. The conclusion from "This time is different" is exactly what common sense would tell you, don't get too much debt or else you might grow less in the future and they got crushed because they did not entered in the extreme math/econometrics analysis. What the article criticizes is exactly what "This time is different" did, it applied less data rigor to point out almost a common sense and yet it backfired, so what is it? Should economists apply more or less "math"? I guess either way, this misses completely the point about economics and dismissing the entire field because of it is ridiculous.
It's surprising how much attention this has had over the last few days, without any discussion of the downside: it's slow.

It's true that it is fast for the power it consumes, but it is way (way!) to slow to use for any form of training, which seems to be what many people think they can use it for.

According to Anandtech[1], it will do 10 GoogLeNet inferences per second. By very rough comparison, Inception in TensorFlow on a Raspberry Pi does about 2 inferences per second[2], and I think I saw AlexNet on an i7 doing about 60/second. Any desktop GPU will do orders of magnitude more.

The Reasons for Success in Life
Because the company was staffed by those developers already happy working in Palo Alto, obviously.

I'm just speculating that there may be more developers who are happy with the East Bay location in the wider pool of developers, not that this was a good move for the then current employees.
The Internet Phone
Parity does not run on the EVM, it's a local node processing a local copy of the blockchain. You can create normal accounts which are just private/public keypairs you have full control of without anything "being in the cloud" or "distributed". What you are referring to might be the vulnerable multi-signature wallet itself, which - once deployed - runs on the EVM. And that only affects a fraction of Parity users.

Note, I work for Parity.
I am not sure of the wording of the proposed requirement but I cannot see why companies (let's use Paypal as an example) can't offer a service where they verify age without releasing personal details or keeping records at their end.

They could even charge a modest fee, perhaps even once off, to provide this service.

It doesn't seem like an intractable problem to me.
The whole point of the TV tax is that the BBC can take on projects that are "worthy" but not commercially viable. Why does it have big-name stars at all? Why is it competing for ratings at all? They want to have their cake and eat it is why.

Working for the BBC is a privilege; one of the few cases where people really should be doing it "for the exposure" and not paid at all.
So what you're saying is that there basically is no room for negotiation, because it would deviate too much from the standard scale? e.g. a company needs someone for X, and will fix pay around €XX,000.

At any big company, you need to make sure they want to hire you first. Once you have done that, pay becomes irrelevant because mentally they have already hired you. It's a rounding error on a budget. And it often is not even their own budget.

You would be surprised at how easy it is to negotiate a €20k salary increase by just saying: I'd love to work here, but we need to figure out a salary range that works for both. And if they lowball you (which they probably will), you just counter and take it from there.
> What can I do in Haskell that I can't do in Clojure, because of Clojure's dynamic typing?

You are making a false equivalence here. This thread started with the implication that the flexibility of dynamic languages is more useful than anything static typing can give, and questioning the grounds for that is not the same as asserting the opposite.
You can't really do any reasonable training on a Jetson.
Statements like this, that allege some group is being victimized, makes scapegoats out of those with more resources.

Yes we're all "economically coerced", by the need to produce economic resources in order to consume economic resources.

It's like Bastiat said 160 years ago:

"Man recoils from trouble - from suffering; and yet he is condemned by nature to the suffering of privation, if he does not take the trouble to work. He has to choose, then, between these two evils. What means can he adopt to avoid both? There remains now, and there will remain, only one way, which is, to enjoy the labor of others."
Great then. Do you have any ideas then how to stop the radicalisation of young muslims? I'm less inclined to believe that rational discussions with ISIS warriors and their supporters will lead that far.

I live in what used to be one of the most secular countries in the world, and for various reasons our government have encouraged immigration from the middle east for 20 years, providing free education, free healthcare, generous social welfare, and an actively non-racist society. Unfortunately, this didn't seem to automatically integrate many in our society, mainly because of unemployment caused by the originally low "human capital", and partly due to there are many cultural issues that wasn't even socially acceptable to discuss at all until recently.

While many have done great, there are many more that haven't and the 2nd or 3rd generation are still doing pretty bad compared to the natives, which has created street gangs and criminality in many areas, even in small towns.

Among many bad things, one of the results is that we now have many ISIS warriors here, and no plan on how to handle them. It doesn't even seem to be illegal to be an ISIS warrior here.

Many more are susceptible to the propaganda, and in my book, any means stop the propaganda is more than welcome. I really don't understand how large US companies can carry messages from violent extremist like it's no big deal.

I don't know, and I don't care, I just see it as a big usability gap compared to Safari. It could use Alexa or something.

But at least it could autocomplete sites I've already visited. For example, say I've visited microsoft.com. The next time I type "micros", it could offer microsoft.com as the first autocompletion, which is what Safari does [1]. Instead you get this [2].

Basic airport screening is useful, but you very quickly hit diminishing returns.
I notice the ebb and flow of productivity as well. Ken uses the term fallow period. I like the reproduction analogy. New ideas, skills, or domain knowledge are like the sperm that finds its place in the egg which I think of as the existing stable but receptive body of knowledge and skills.

There is often excitement at the beginning "I have this new skill!" However, the new skill or knowledge hasn't really integrated with the existing body of knowledge yet. Then often it seems that there needs to be a gestation period. You have the sense that connections are forming and something new is forming that is the combination of the new and the old.

And, then it feels like I am ready to pour it out. Whether it is writing an article, preparing a speech or coding up that feature or application. When that happens it feels like the "Flow." But I understand that the gestation period was just as important if much less visible and seemingly unproductive.
Big difference between UK and US defamation law is that the burden of proof is reversed. In UK you have to prove that your defamatory statements were true but in US the defamed party has to prove they were false.

I'm not a lawyer, I'm not your lawyer. If you need legal advice or need to make a defamatory statement get real legal advice.
Confirming this always was and still is the case. (Working for Parity.) However, this does not guarantee that such mistakes happen.

What about some authority like a professor who writes a book about his subject? Suppose the guy's been paid or heavily subsidised through his career.

Seems a bit unobvious to me. On the one hand, the guy's gotta bother to sit and write a book. OTOH, his book would be worthless if he didn't have the skills paid for by other people.

I guess what's normal is that we disregard how his expertise was funded and just let him keep whatever he makes. After all, he doesn't have to write a textbook.
"To put it bluntly, the discipline of economics has yet to get over its childish passion for mathematics and for purely theoretical and often highly ideological speculation, at the expense of historical research and collaboration with the other social sciences. Economists are all too often preoccupied with petty mathematical problems of interest only to themselves. This obsession with mathematics is an easy way of acquiring the appearance of scientificity without having to answer the far more complex questions posed by the world we live in."

Piketty T. "Capital in the 21st century", p. 36.
All these articles from opinionated outsiders aiming at "stimulating debate" sound extremely arrogant to academic economists. Do you really think you are telling anything new?
There are also videos made by murderous dictatorial regimes as a recruitment tool. YouTube has no problem with that. There are videos made by US to get more cannon fodder for their wars which also killed millions of innocent people over the decades. Where do you stop?

I'm fine with stopping recruitment videos for war, but at least do it on principle as against the war, not just against a few particular organizations. It's ridiculous otherwise. It's just one belligerent suppressing the other one in a conflict. Nothing else.
I don't buy argument. It confuses economics used to advance political or commercial goals with academic economics.

Economics is far ahead other social sciences because it uses mathematical modelling. Models make it easier to see the limits and the scope of the arguments. Ability of outsiders to clearly see oversimplification s is strength.

Rational actor model is the best first order approximation of behaviour. Moving to others, there are others, should be justified carefully.

Other social sciences have it worse.

Btw. Economics is only partially social science. Actors don't have to be humans.
A thousand time yes.

Free will only makes sense in the context of an individual
Actor. So we can talk about my free will for example. But for that free will and the choices I make to be mine, they must logically be dependent on my state at that time. If they are not determined by my state, then those choices are in no way mine. Furthermore in order to be free choices, they must not be primarily determined by external influences such as threats or misinformation.

This is not a tautology. It's a necessary requirement if any choices are to be ascribed to an agent that the state of the agent must determine the choice. Why this is in any way controversial really eludes me. So are our choices pre-determined? In the sense we are talking about, yes. Is that a problem philosophically? Sure, but philosophy and the real world have no obligation to be convenient to our expectations or desires.
The same bad arguments against economist repeated again and again. The people who write this are either stupid or simply write what people want to read.
> Can someone explain me the technical details as to how the mirroring of the website didn't raise any suspicion from the customer or buyer side ?

I don't know any of the specifics in this case, but generally speaking, that would not be a user-visible change. The police had access to the hidden service's private key and could simply announce the service from a new location, keeping the same URL. Tor hidden services hide the location where the service is hosted (at least from regular users, less so from more powerful adversaries).

> The banner there mentions that the source code of the website was changed to allow such behaviour which makes sense. However, this should only put the new buyers/sellers at risk and leave the old ones safe. What went wrong ?

I don't know if they've mentioned whether they have busted only users that have used the site after the takeover - they got a massive influx of new users after AlphaBay went down, so that could've been good enough for them. Based on past cases, I imagine there were plenty of OpSec mistakes that could've lead to a bust either way.

(This is probably a good example for why browser crypto is currently a bad idea.)
Great point, in fact I've been bird struck whilst riding a motorcycle and that's DANGEROUS.

It's simply called authoritarianism. The problem is that the left AND the right are authoritarian. The benefit of all those 'anti terror' laws is not only not proven but also largely debunked, however, you just need to instill a bit of fear in the population and they give up all their oh so cherished freedoms.
