> Could someone surround my node with malicious nodes and put me on a forked chain?

Yes. You can’t know about blocks you don’t hear about. However:

1. Unless they can match the hashing power of the rest of the network, they can only publish new blocks to you at a very low rate (e.g. every 100 minutes if they have 10% of the hashing power)

2. If you connect to just a single node which tells the truth, you will discard the forked chain (again, unless the attackers can match the hash rate of the rest of the network)

All in all, proof-of-work makes it pretty easy for you to notice that something weird is happening.

> How does bitcoin protect against this from happening by accident?

You can prevent nodes from connecting to you (no inbound connections), such that you choose (randomly) which nodes to connect to. Choose a sufficiently high node count, and you’re almost certain that you don’t select a group of coordinating malicious nodes.

Side note: It would also be interesting to analyze the impact of this attack in the context of a proof-of-stake blockchain. I assume, although I’m not certain, that the attacked node would just consider the current stakers as defunct if the attackers don’t deliver blocks from them, and that the attackers would be able to become the new stakers, since the attackers would be able to censor competing staking transactions.

Distances in RGB space certainly mean something in the sense that you get a rough approximation that gets more convincing the more colors you quantize to. Decent for some purposes, while for others you need a space that more closely maps to human perception.

The problem with the hacker mindset as it applies to algorithms affecting lives is that most folk who studied computer science ( or any of the hard sciences for that matter ) usually went through programs that never approach the human interaction beyond, how to hook the user and keep them involved.

CS majors should be required to take at least 20 hours of philosophy or history. Or, be required to do 20 hours of community service. It's too easy to live in a code bubble and forget the rest of the world lives on $2 a day. That's why we have Uber which solves problems for the first world and the third world remains a disaster.
If you want to go down that road, you'd want to divide by value.

(And to make it more efficient and objective, charge a (global) land value tax and use the proceeds to finance a (global) basic income. The average person will have a net impact of zero, but anyone using less land by value than the average will be reimbursed for that generosity.)

But let's get back to the math.

I don't believe she's necessarily calling for the hiring of humanities grads.

What would help, as a start, is an appreciation for the values (and value) of the humanities.

On HN specifically, you frequently see something akin to Schadenfreude when referring to students of the liberal arts serving fries to tech grads. That is to some degree just factually wrong, considering many liberal arts undergrads go on to rather lucrative careers in law, or powerful careers in politics.

But it is also short-sighted, because history has always been a two-step process, with technology enabling us to do new things, and other disciplines enabling us to use these capabilities for something resembling the "common good".

I always like this thought experiment: Would you rather live in a world with the middle age's social/political/law system and today's technology–or the other way around?

This doesn't mean that social and political progress are the exclusive domain of those who studied greek mythology. In fact, this article explicitly argues that it shouldn't be: Hackers should engage with that community.

But what it does take is, sometimes, a bit of humility. Too often, I feel the tech community is looking at technological solutions to social and political problems. See cryptocurrencies, or the encryption debate as examples where you can feel cynicism, bordering on disdain, for the political process.

The problem with that is, first, that it's wrong: a lot of power rests in politics, and China is a living example that the internet community is currently unable to win a direct confrontation with the power of the state. It is also wrong in that it portraits all governments as equally bad, all laws as subject to changed or broken when expedient, when clearly there are differences in the rule of law between countries, and there are differences in the willingness of politicians to act with integrity.

Secondly, using technology to create facts is somewhat undemocratic in itself. The Federal Reserve may be committing all sorts of errors. But it is hard to deny that derives legitimacy through a transparent, tested, process much more democratic than bitcoin. It is also an illusion to suggest that bitcoin is free of ideology, only because that ideology takes the form of an algorithm decided in the past, ticking away with almost no method to influence it.

Doomsday Prep for Reasonably Rational People
Anti-immigration sentiment in the UK is to a large extent driven by lagging infrastructure.

As just a single example the housebuilding industry has been consistently able to build fewer houses than there are people arriving by a large number, and the statistics over how many people are arriving are themselves deeply suspect - they don't correlate with any other population related statistics, and are based on airport surveys that ask a subset of people whether they plan to stay for a long period.

If politicians allow immigration at levels significantly above the speed at which infrastructure can be built out to support the new people then infrastructure reliability and availability will decline. It is reasonable to be concerned about that if you rely on that infrastructure.

The idea of Brexit voters as incorrigible racists isn't supportable, no datasets of any integrity show that and the brief spike of "omg britain is so racist" died down very quickly after the referendum, simply because the UK is and remains by far the most racially diverse nation in Europe.

Not to derail the train, but it is hard to take anyone serious on the subject of Communism with statements like that.

More or less any numbers you see about the predicted economic impact of Brexit come from exactly the same sets of economists who have been proven 100% wrong so far about everything, so have no credibility. They predicted a massive recession in the wake of simply voting to leave, not actually leaving, which never materialised. Then there were claims it would be triggered by the formal notification of leaving - that didn't happen either. They also liked to claim that immigration had no impact on wages, but there have been quite a few stories since about industry leaders complaining about having to increase wages (suspect in and of themselves because immigration hasn't really fallen).

There simply aren't any economic projections of a trustworthy nature right now.

That's according to your definition of democracy and communism.

To give another example: the Athenians had very different definitions of democracy.

A lot of people derive enormous comfort and security from the belief that there's a social class who can predict the future. In the past they were shamans and oracles reading goose entrails, nowadays they're analysts and economists reading Excel entrails. In the Foundation trilogy they were psychohistorians, basically economists on steroids.

I think it takes a certain amount of bravery to accept that there are no "experts" when it comes to predicting the future.
I don't know how commonly known that is, but Hitler was a bohemian and failed artist before World War 1. While his paintings were quite bland and uninspired, he could draw and paint.

I can only offer a guess at what dang thought was a personal attack, but I can opine on what is a personal attack independently.

There are different contexts in which different levels of evidence or backing might be supplied, but the first thing I noted is that you don't explain why the things you mention are relevant. "That is not why women earn 20% less than men", regardless of if it is true or false is clearly relevant to the discussion, but why is what someone "sounds like" relevant?

Also, there is enough information in the above claim to search on it - or at least the claim can be refuted and thus begin an exchange of evidence. But your claim is about the character of the anonymous person you are talking to. Claims about a population of people, brought up in a relevant context is not disrespectful (possibly, depending on the legitimacy of the claims, but that is yet to be decided); Making remarks out of context about an individual is entirely different.

> that is not supported by any reference and it is also false

Who says it's false? Just say you don't believe the claim, and ask for evidence, or make a counter-claim of your own.
> One, I am tired of the notion you have to be in a coastal city to be successful (SF, LA, Seattle etc).

Economic growth has not been equal, though. I live in Springfield, MO. I have plenty of certifications, a degree, and a year of tech support experience, yet it's been extremely tough to find a job that I could find in a heartbeat in a tech hub.

> Two, as a tech industry we need a wake up call that a tremendous amount of talent comes from foreign workers and we should be more thankful of this.

Shipping in foreign workers(and outsourcing) is part of the reason it's tough for me to find a job. The labor market has been kept artificially loose, which removes the incentive to develop the economies of more "rural" areas of the country. (I live in the third largest city in my state, so it shouldn't really be considered rural, but I digress)

> Fourth, I think as a country we have to understand the real economic pain experienced when we no longer have access to overseas talent.

Wages have been stagnant yet return on capital has been increasing massively. It seems to me like our problem isn't economic growth, it's distribution of that wealth. When Americans compete with people in lower costs of areas, lower expectations for their quality of life, and less leverage, it hurts American workers just so the owners can maximize profit.

Middle class jobs have been shipped overseas and lower class jobs are being displaced by illegal immigrants in many states. At what point should we do something about that?

There are a few other pictures and how well the medium of Lego works for pixelated art.

There are a few people on this thread posting 'things made with Lego' which is a different thing to using Lego for pixelated art.

I think that you could build a small business out of making pixelated Lego for people wanting to buy their new-borns some Lego. Imagine if in the bedroom the Lego starts as a bright picture on the wall, out of reach. Then when they can reach it then see what happens. If they have no Lego then do they work out that you can make things with it? Or do we need marketing and instructions with box artwork?

Also interesting would be a Lego sorting machine that you tipped random bricks into for it to then print out as pixelated art. It would scan the bricks and then show you exactly what images you could make from the bricks and also dither a given image to the palette and availability provided by the bricks dropped into the sorter.
It is pseudonymous, so if you did work for someone over the internet and never met them, they could pay you without ever knowing your name and address. If your adversaries were looking to trace the coins they would see a transfer between 2 addresses only. If they managed to track down the owner of the sending address then that person could say they paid you for work done and pass on whatever contact details they have. So unlinking can be done and this is based on the adversary knowing which transaction and who the sender was.

I think he means that there's a lot of debate when you peel back the covers on how much modern trade deals really impact economic growth. And quite a lot of evidence that they have surprisingly little impact.

If you go read press releases made about trade deals they always have apparently huge numbers but spread over a very large number of years. Modulo what's said elsewhere about the uselessness of economic predictions, the predicted impact is usually very low. Probably because tariffs are already quite low and falling globally, most trade barriers are now regulatory in nature and those tend to be relatively unaffected by trade deals.

It's only a puzzle if you think that everything has to have an economic and/or evolutionary explanation. Christianity is a huge factor in the prevalence of monogamous marriages in the West, and indeed, attitudes towards monogomy are changing as fewer Westerners are practicing Christians. Conversely, Christianity is growing pretty rapidly if you look at the world as a whole.
> At what point does it become yours?

At no point does it become yours. I'm pretty sure that, while you can't necessarily prosecute the person currently in possession, you could almost certainly recover the property if you could prove it was stolen from your estate.

Added: In most English speaking countries it becomes a crime to willfully possess stolen property as soon as you know that it is stolen. In general, the lack of mens rea in merely possessing stolen goods would make it enough to repatriate the goods, but if that's not enough, most statutes on the matter explicitly state that you must know and wish to unlawfully handle the stolen property.

the EU's goals is to serve the collective best interests of all and every single member-state

That's clearly not what it's trying to do right now. For one the UK is still a member state and still paying its dues, but the EU is acting in an extremely hostile way. Unless you reflexively define the best interests of the EU Commission and related institutions as "the best interests of all and every single member state", it is certainly not the case.

Consider: The EU is setting things up such that in just over a year trucks will start to pile up at ports, costs will rise across Europe and the UK, many European firms will be cut off from the financing they receive from London, airplanes will be grounded, Irish politics will destabilise due to the introduction of a hard border and that's really just the beginning. None of this is in the interests of any person in any EU member state at all. And it can all be easily avoided.

Your spa analogy is very badly off by the way. Trade isn't something countries sell like a product itself, despite the EU's attempts to package it that way. Countries that strike free trade deals do not "buy" them, they negotiate and agree to them. Think about neighbours cooperating more than a consumer buying a product.

This sounds suspiciously like either a) choosing who to trust in advance, which negates one of the few benefits of blockchain-based cryptocurrencies that I accept exist (even if I don’t value it highly); or b) relying on random numbers being both fair and not being tampered with, even though over-reliance on that is one of the common failure modes with cryptography in general.

Yikes, doing a color conversion by nearest-neighbor RGB is guaranteed to give odd results like this. The entire center of her dress has undershot the blackpoint and is washed out entirely in black, and the representation of the headdress is extremely high variance. These are similar problems to people what people face attempting to print out digital photos or artwork without properly managed color.

At a minimum you would want to adjust the color gamut of the image by hand to line up with the lego color gamut so the end result is more pleasing, more concretely that means spending some time on the hue/saturation/lightness/color curve filters until those conversion artifacts are minimized. A more theoretically interesting way to do it would be to use a gamut matching algorithm with a discrete color space defined by the available lego bricks.
