Bitcoin Cash has a separate blockchain (and peer-to-peer swarm, etc) but uses the same address format and checksum as Bitcoin. Bitcoin Cash did that on purpose so people's addresses from before the fork would continue to work if they moved to BCH at the fork. Personally I think they (BCH) like the confusion because it keeps people talking about them where Bitcoin is talked about (never mind the confusingly-similar name).

Coinbase technically could make the addresses they show be able to receive both BTC and BCH funds, but it would be more complexity on their end as their BTC and BCH support would no longer be separate systems.

There is a plan for Bitcoin to get a new type of address format eventually (BIP 173, "Bech32"), built specifically for Segwit addresses, so this problem will eventually be addressed. Well, it will be fixed until the next Bitcoin Cash Gold Deluxe Whatever fork shows up...
Even the word "disputed" is too kind. The U.N. rejects the claim, which is based on fantasy (and force), only, not history. It doesn't even rise to the standard of revanchism or irredentism, which are disreputable, too.
It wouldn't work unless everybody including the gamers were willing to preorder a year or more in advance, because if the bottom fell out of GPUs for cryptocurrency then everyone who preordered for mining would immediately turn around and resell them and flood the market.
Not using cryptocurrency is cheaper than proof of work.

Folks are getting involved in the community planning meetings, which are a major way here for potential developments to get more visibility.

In SF this week there's a case of a man who owns a laundromat, and would like to turn it into a 75 unit apartment building. It sounds like he met all the objective criteria and is getting stonewalled by NIMBY's due to the usual excuses: "neighborhood character" and historical value of the building. The building is a laundromat, and by all appearances fairly mundane and not at all historical. I can think of no obvious opposition a reasonable urban planner would have to this development. Yet it's being stonewalled. What undesirable side effects would it have? I grew up in New York City, which is also dense. People love living there. What's wrong with SF moving in that direction if it means accommodating all the new residents AND providing reasonably priced housing to all the current ones. Pardon the rant, this issue hits close to home for me.

Edit: Re your earlier point on SF geography, earthquake proofing is a well developed tech. It will add some cost to development, but that doesn't make it infeasible. I live in a part of the city where they had to drill many many feet down to bedrock. It can be done.
They are absolutely thrilled about the demand, and very reluctant to bank on it going forward.

While I appreciate your questions I get the feeling that your trying to poke holes in a very well researched and funded project based on what you read of it in my comments.

There's much more to the project and a lot of brilliant people with over a billion dollars in funding making sure this thing is bulletproof. So if you're interested in learning more about it I'd recommend you read their whitepaper as it will be a much better source of information.

Building a Distributed File Sync in Ruby
As I said above, Dropbox's real competitors (Microsoft, Google, Amazon, Apple, Box) all follow a similar approach and don't use E2E. The ones you mentioned are very niche.

The technology just doesn't exist to give users an equivalent experience with equivalent features when using E2E. I wish this wasn't so but it is.

HTTPS is transport layer encryption that goes seamlessly over HTTP and doesn't change anything at all about what you can do online. With E2E giving users collaborative folders, shared links, online browsing, password reset, etc while still providing zero knowledge encryption is a huge technical challenge. If you're doing decryption locally in the browser you still have to trust the company not to just add some JS to siphon off you decryption key at any moment.

I really do want to live in a world where E2E is in more places, but with cloud file solutions there's just not a way to do it right now that gives people the features they want and the market share of these companies is showing that.

> Let me ask you back. Can you prove with 100% certainty that banks are more "efficient" than bitcoin? What does "efficient" even mean? Did you take into account all the jobs required to run the banks? Did you take into account all the energy these bank employees consume? Did you take into account all the side industries that arise around banking system?

What? I thought you said you were well versed in economics. This is literally one of the core concepts for the benefits of economics because you can evaluate things on their "efficiency" (costs) versus the value they provide (revenue). Every "job", "energy cost", and "side industries that arise around banking system" are evaluated in the cost to run the business and if they were greater than the value they provided, they would not be in bunessines because revenue would be less than sum of those costs.

> Did you take into account all the corruption that took place over and over and over throughout history that eventually took everything down to zero?

Obviously corruption is not good for our systems neither are other economic problems such as negative externalities [0]. However, I don't see how cryptocurrencies solve them in a way that makes them better than current solutions as a whole.

> This question is really meaningless when you consider all these factors.

I'm not asking you to write a phd. Just give me one good economic use case outside of illegal markets for cryptocurrencies that is better than current technological solutions.

As someone at the end of their undergrad, I have to agree that group based projects trend towards being unpleasant. The article describes the distribution of work harming full understanding of the content when all people contribute, however that's usually the best case.

Most students are oversubscribed with four or five classes. There tends to always be some portion of a group which contributes trivially or simply doesn't. When you've got a group of five, one is typically unreachable, apathetic, or just exhausted. Pairs are a gamble, a bad partner being a massive workload. When you're the person who's carrying the group, you usually end up grokking everything in the project because you touched all of it. However, since you touched all of it, you're exhausted and likely pissed.

What I've found works is individual work sample projects, particularly those timeboxed to 'hopefully a lab period but you have a week'. The GPGPU course at my school has labs which are 'fill in the blanks' for cuda code. As the course goes on, those blanks get progressively more complex and make you flex your core understanding of the course. For more theory driven courses, the standard set of assignments works nicely.

As an aside, group projects seem to be partially motivated by the TAs and profs trying to deal with larger class sizes. Taking a senior level graphics class with 30 people lets you write 4 gnarly opengl projects which the TA marks in depth; a software engineering course with 200 people, a weekly deliverable, and 5 TAs? Dividing that by 5 is more realistic.

(For context I go to a school not known for their undergrad CS program; experiences may differ in other institutions)
"First, the argument is ridiculous because Bitcoin is already doing something useful for society (mining wouldn’t be profitable if it wasn’t)."

Errrr, no. That's not how things work. Mining is profitable because it produces bitcoins which are valuable. Whether they are valuable because they are useful to society or because of some other reason is unclear.
> Assuming Craig Federighi didn't perjure himself, why has China seemingly made an exception for Apple when it comes to iMessage (or iOS or iCloud)? The answer is that Apple is the only tech company that actually has leverage with the CPC in (indirectly) employing millions of workers in China.

Eh, there’s a simpler explanation: Basically bobody uses iMessage in China.

Employing people in China is only leverage is they can readily move production elsewhere (nope, not at that scale).

Not that it counts for nothing but the real issue here is iMessage is just a non issue for China.

> So, for programming, we need to (1) figure out the core concepts to teach, and (2) pick languages that make the concepts readily available.

James, the main argument for project-based learning is ability to make learning interesting. Considering that students aren't vessels that need to be filled, but torches which need to be lit, this can trump other approaches. Importance of being interested in the material can be hard to overestimate.

You may still be right, but I was surprised to see the arguments for project missing this one.
Agreed. So many technical blogs try to strike the same to to sound edgy or cute. Here the author uses it masterfully to reinforce his points on language.

If two people were racing to "learn" a programming language then yes, project based learning would fail.

This dude doesn't recognize the audience that most blog posts target.

Most people reading blog posts about learning code are NOT in college and ARE NOT employed by colleges.

So the challenge for learning is more about motivation and projects tend to help you stay motivated more easily that little learning lectures and components.

Everybody's up in arms over the fact that the FCC reverted the Internet to the same level of governance that it operated under from its inception up until 2015.

I submit that these people are sheep and just braying along with the herd.
I don't understand what exactly is the reason people don't like Eclipse. The features and the overall feeling of using the IDE is great, that's why I am still using Eclipse (mostly Java and Scala development), so are many of my colleagues. I guess there are some downsides, like slower leading times and a bit clunky compilation process, but other than that, it's a solid IDE.
> Rich people will often look for ways (not necessarily conspicuous) of asserting their status.

The point is that non-rich do that, too. Most people buying luxuries are not ultra-rich. $300 dollar chocolate is not out of reach for the upper-middle class, or really even the regular middle class. It might be a dumb purchase, but you could realistically earn less than $50k/year and still buy a bar of this.

I would imagine that my peers make up a much larger portion of To’ak's clientele than Warren Buffet's peers.
I am not familiar with the specific case you are talking about. But one of the reasons we have this mess is due to historical efforts to improve things that resulted in the elimination of a lot of affordable housing. I have seen lots of examples of zoning gone wrong and stated goals being achieved, but with unexpected costs.

I don't remember it as clearly as I once did, but the Aswan Dam met all its stated goals of providing electricity and controlling flooding. But it cost vastly more to build than expected, silt build up was much faster than expected, leading to a shorter lifespan than expected, it caused a terrible schistosomiasis epidemic and farmers had to spend huge quantities on fertilizer. They overlooked the fact that the icky flooding provided free fertilizer in the form of rich silt. They overlooked the fact that the icky flooding is why Egypt was The Jewel of the Nile for thousands of years. They didn't recognize that the icky flooding also kept the snail population under control. The snails are the vector for schistosomiasis, a horrifying parasitic infection.

Lots of efforts to fix things go sideways. It happens all the time.

I feed my purebred English bulldog:

He started off on royal cabin puppy bulldog blend.

Then I was a little smarter, and fed Origin.

Origin I found was true protein rich.
Switched to Acanna, which is actuallyade by same people as origin, just less protein.

Tried fromms, taste of the wild.

Then nutrience grain free with freeze dried meat.

I have used this a few times inbetween, but now back on it.

Hypoallergenic meat first recipe, with no Corn, grains, Wheat, Soy, Dairy, or Chicken, Chicken Eggs, or Chicken By-Products.

My Dog is allergic to chicken, suprised how much chicken meal is in alot of dog foods.

They pet store basically said: "has your dog ever had kangaroo? unlikely, and its only meat in it.)

So I tried it, maybe not the absolute most favorite of my dog, but he still enjoys it and it's been the best for him.

Never tried blue origin, likely won't now, my wife' heart always dropped watching the commercials telling the history of blue the dog and the resulting company in memory

I think a implicit-trust powered blockchain is provably cheaper, provided you can guarantee trust for a sufficient amount of time.

One such example I can find is Luckychain[0] which is where I'd start if I was going to attempt something like this. Intel SGX is the closest thing we have to a legitimate system in which we can place trust in the client. That being said, it requires trusting the signer, Intel. And we have to trust that it can't be cracked even with government-level capability, for the duration of the network's lifetime.

I wonder if you could somehow move the job of signing onto the blockchain itself, so it becomes self-trusting and autonomous.

This article reads to me like someone arguing whether it's better to learn by reading or watching videos.
Maybe both? Neither?

For me, what good is it to learn all of the fundamentals if I'm not sure those fundamentals are getting me closer to my goal?
Especially in the world of tech, there is no short supply of "critical fundamentals", but woefully less in actual implementation.

And in the tech world, there's a lot of implementation that lacks even a cursory understanding of fundamentals.

IMO, this isn't a problem in the approach of learning, but the learner stopping at a superficial understanding on either side.

Some people don't like to jump into new endeavors without understanding the concepts. And others don't want to be bothered with abstracts until they can see the results.

Good students beat bad ones, regardless of the journey that took them there.

A manager's role is three parts: information routing, training, resource management.

A manager collects information from a team and abstracts it to upper management. Upper management can then use this info to understand what the organization is capable of.

It's also the manager's job to understand where the company is going, what the strategy is, and communicate this effectively to the grunts.

They also relay and filter out information between departments. They help engineers understand what sales (and clients) want, and sales to understand what the product is capable of.

They suss out flaws, normally with people. Sometimes engineers might not be willing to voice out concerns.

The engineers might also want more resources, whether it's an outside service, hardware, more manpower. The manager looks at this from a higher level and finds the best solution. They appeal for budget increases and extend deadlines.

And if you have a really skilled dev turned manager, their job is to mentor and train. This is possibly the most effective thing a manager can do.
Stack Overflow stalling
Yeah but the problem with the current method is introducing solutions before the problem. Learning a tool is way easier if you see the value of that tool. I had assignments writing XML schema. No idea why but we had to write them. I didn’t retain any of that but found them very valuable to define interfaces later on. If I’d known the use I’d have been more motivated to learn how to create them.
I'm glad they've gone for global availability, but I'm still not a fan in my own personal sense for using this.

Liberal / conservative are usually used as shorthand for specific political philosophies.

Many mainstream American conservatives refer to themselves as classical liberals, and they are correct. Liberal, in the American parlance, on the other hand covers a wider gamut, from centrists who favor technocratic regulatory regimes and government nonintervention in personal affairs all the way to progressives who favor income redistribution and widespread social engineering policies. (Clinton and Sanders camps in the Democratic party respectively.) There's also an emerging hard-right anti-immigration / "nationalist" fringe. I take no issue with your points but object to the terminology which masks the complexity of the situation at hand.
> inspiring a more long-term view of the world and our place in it

I fail to see how that is pertinent. We know the world will still exist in 10,000 years, but we have no idea what it will look like. The mere existence of a clock that could potentially still be running then doesn't change anything about that, does it?

If anything, celestial objects do exist and provide some kind of a natural long term clock. I really don't get what a mechanical one hidden in a mountain adds to it.

In Portuguese, although ‘sim’ means yes, when answering a question in the affirmative you often use the same verb as the question.

For example: “Gosta frango? Gosto.” “Do you like chicken? I like it.”

Also, it’s common to say ‘isso’ to agree with something. It means ‘this’ and Anglophones are now doing the same thing, at least online.
That's not always true. It may look easy to start a company and make it at least a moderate success in Silicon Valley today, perhaps due to the easy availability of money and helping mentality from peer companies who would jump into trying your product and even paying for that because they themselves got easy money from cash rich, aggressive investors.

But it is not the case in traditional markets other countries where you have to put lot of time, effort, our own money and mental stress into creating even a moderately successful business.. On the other hand employees get relatively less strain and a stable income and an option to leave the company anytime and move to better higher paying jobs.
The author is not criticizing project-based learning in general, but instead how some curriculum (I wonder who's?) uses group projects as the only form of learning.

This feels a bit like a strawman. I agree group projects are not the best way to teach individual concepts. However, they're the best way to put what you've learned into practice. To use the author's martial arts analogy, group projects are like sparring in a safe environment.

Group projects are also the best way to practice your group communication skills, something isolated exercises cannot help with.
