True, Decentralized systems != Cryptocurrencies, but email, BitTorrent, and Git are different from what Bitcoin, Ethereum, and other blockchain system provide.

Blockchain-based systems allow storing a shared, verifiable state. Anybody has a chance (depending on mining resources) to make a decision regarding the next state change in the system by mining the next block, but this block will be rejected if the state change is invalid (e.g., in case of Bitcoin a transaction spends non-existing funds).

This is very different comparing to existing technologies that usually store state in a centralized place that is owned by a single company.

A benefit of full decentralization that is commonly mentioned is that this system is hard or even impossible to censor since even if a nation-state decides to stop transactions from a single actor, mining nodes in other countries will process these transactions fine.

Another benefit is that since all state changes are verified by every other node, it is impossible to perform invalid transaction changes. For example, a bank can reduce everyone's accounts by 5%, but Bitcoin network won't do this.

My questions are: how important these benefits are for practical purposes (mind that we are talking about public, permissionless blockchains here), and can we go away with faster but less centralized systems like NEO?

It's a movie cliche. Shot on the left side, you are a gonner. Shot on the right, you'll be just fine. So you don't have to worry about whether your favorite character is going to make it to the end of the movie or not.
I was always suspicious of the magical 'one glass of red a day is actually GOOD for you!' - seemed like a major case of wishful thinking and confirmation bias.

Alcohol is fun to many people - including researchers. This has driven an almost desperate attempt to legitimate drinking in nearly any context. Drinking daily? Good for you! While pregnant? Probably not bad! Breastfeeding? Sure! Just social drinking once a week, but a little bingey? Well that's like an average of 1 drink/day, so it's also good for you basically!

I quote a friend who is a psychiatrist: there is no known safe level of alcohol.
I also rarely sleep on flights but find the best chance is putting on a movie I wont like (and even better if I've already seen it) and attempting to watch it.
Serious question: Would the Volvo system have picked up and appropriately responded to the gore point involved in the recent fatal Tesla crash? Any time anyone raised the question of Tesla's AEB's reliability, the responses were along the lines of "no AEB is perfect", "AEB only works on cars", etc.
good news is that is not something I keep up. Out of my 11 years ib reddit and however long here this is the first time I am saying out loud that there will be a correction in within a next year or two.

I think this is a combination of great safety equipment, the safeness of the car itself (crash tests and so on) and the people who buys it. Its not the most hardcore drivers who buys a Volvo, even tho the 2017 and newer models are really good looking. Volvo has always been a pioneer in security as well

My girlfriend receives ketamine treatment for her depression, so I’ve the results first hand. It’s truly astounding. She’s seen more improvement from the ketamine than from a decade of psychotherapy and traditional psychopharmacology.

The only downside is the cost (it’s not covered by insurance) and the potential that there are long term side effects that have yet to be discovered. We pay $375 for a 40-minute infusion. The recommended initial course is six infusions over two weeks. After that a booster or two is usually needed very two to six weeks. (It’s been about every three weeks for my girlfriend.)
Have you driven it? I didn't, but my current car is a similarly-sized Seat, also 4 cylinder. It's quite snappy for its size, snappier in fact than all US cars I personally drove (though, tbh, in the US I've never been in a hurry, and I tend to drive 100% legally because I'm not in the mood of familiarizing myself with foreign/US law)

> But don't go too far and substitute authentication for network isolation. Vulnerabilities are a thing.

I don't know if I still agree with this. One of my most important and private services is exposed on the web - the most untrusted network on the planet - and it's using application layer authentication, and no network isolation.

I don't need a vpn to get access to my gmail, my web banking or my nextcloud instance. I can access all those services over the most untrusted network of the world with a username and a password (and maybe a second factor auth token).

I think network layer isolation is overvalued. In the end, you still have to secure all your local lan resources anyway, because trusting your lan clients is never a good idea. So if your lan is untrusted like the wan network, and you secure all your stuff in your lan like you would secure them if they where exposed on the internet, there is no need for network level isolation at this point. Sure, it's an other layer of security and all that, but that comes with a high cost, that not always is worth paying for.

True of course, but: 1) Any other open source OS would have exactly the same problems. And 2) They wouldn’t be any easier for them to solve, so why not concentrate efforts an solving it on AOSP which already has an ecosystem?

Yours is an argument why all struggling OSS mobile OSes are struggling, not particularly why AOSP has problems. Surely if even AOSP is struggling to solve these issues, what chance do the others have?
Search Giant Baidu Unveils Blockchain Photo Platform
It works for me, in a really remarkable way. My bike broke down twice last year, and I couldn't ride for over a week each time; it was really remarkable to notice how dramatically my mood improved when I got the machine back. I hadn't noticed that I was getting depressed, but I sure noticed the feeling after I got back on two wheels - like drawing in a deep breath, as clarity and calm returned.

Sometimes I use the bike that way on purpose, not to go anywhere but simply to improve my mood. A quick run out east on the highway, up to the mountains and back, will usually knock me out of whatever loop I've got stuck in. I think it has something to do with the way that you have to stay present, immersed in the moment, aware of everything going on around you; there's still some room in the brain for higher-level thought, but you have a base of calm presence to work from.
I don’t know if there’s a specific term, but it’s pretty basic design in pretty much any retail store. In grocery stores, they put high-intent items like milk in the very back. In grocery stores and convenience stores, the checkout area is filled with low-cost (and presumably high-margin) products (like snacks) that are likely to be impulse buys.

I don't recall "trustless" being one of bittorrent's main selling points?

Further, to accept crypto as payment very much requires trust (or faith or belief or whatever you want to call it) that you later find some third party that is willing to accept your coins as payment, preferably with roughly the same value that you assigned to it in the first place.

Awfully lot of trust flying around in a trustless system in my opinion.

>My god, the author of this story made all the wrong choices.

Did he? He kept his job, didn't get drunk or hooked on pain pills, bailed out what sounded like a very uncooperative ex-wife, and all through it kept his house clean and even took care of the neighbor's dog. If anything, I'd say the story comes dangerously close to being a humble brag.

Whatever money difference there was be between him and pretty much any of the others, including the couple who skipped town with pizza on the counter...I'd gladly pay it twice over to have neighbors like this guy.
Sudden curves in the road when there are parked cars is the biggest issue for mine. I think it plots a path based on how my wheel is turned. When there's a 10-15 degree kink in the road, I can't turn early or I'll cross the center line, so it thinks I'm going to continue straight into a parked car. Hasn't brought me to a complete stop, but it could certainly mess with a tailgater.
It's trying to be the former but is still the later.

Lessons from cybersecurity exits
I find the best way when going to reversed time zones;

1) Fly in a couple days early where possible. Sightsee or work remotely before you hit the meetings etc you're over for.

2) If you have to hit the ground running, sleeping tablets. I use short action ones so it gives 4hrs sleep (and usually more naturally once you are asleep) which is a game changer for my brain function getting a >3hr which can happen without. Obviously speak with your Dr etc. And probably not best if your a frequent traveler.

Electricity marketplace is a good example and is commonly mentioned as a killer-app for blockchain technologies. But what technology would you use to implement this marketplace?

Would you use a public, permissionless blockchain like Ethereum or should we use a private blockchain? There are private blockchains like JP Morgan Quorum (https://github.com/jpmorganchase/quorum) that is based on Ethereum software and allows to have >10K transactions per second. These private blockchains use different consensus methods that are much less decentralized than public Ethereum, all participants are known, and access to the network is restricted.

Would a private blockchain be a better fit in this case?
If you would a public blockchain, could you elaborate why?
> Not surprising: Keynesian economist doesn't like Austrian economics explanations.

When an Austrian economics fan says "Keynesian economist", it's like a creationist calling any sort of scientist who disagrees with them "evolutionary".

Coppola's assertions on history are reality-based. If you have particular objections, you'll need to go into more detail than just saying "Keynesian".

> Surprising: Bitcoin part is largely left uncriticized.

This was largely left to my review: https://davidgerard.co.uk/blockchain/2018/04/07/saifedean-am... He makes a lot of assertions about Bitcoin that are simply factually untrue in plain English, and would only be barely true even being generous in assuming particular jargon.

To Ammous' credit, he appears to know more about the Bitcoin sphere than about ... basic economic history.
I'm not a chemist either but as someone who as partaken and knows other people who have also partaken, the dosages you have to take in order for this to become an issue are way beyond what would seem reasonable for someone who's not heavily dependent and tolerant.

You would have to be taking grams and grams of the stuff on the regular; infrequent or one-off dosages won't cause bladder damage.

Edit: even in the article you can see that the guy developed "K bladder" after taking 15g per day. 15g is a truly scary amount of powder to be ingesting.

'There is no such thing as past or future': changing how we think about time
The cost of a switch is non-zero. For IPC you need to switch out the process running in the CPU, for Syscalls to drivers a microkernel will have to switch into priv ring, then out, wait for the driver, then back in and back out, as it switches context.

A monolithic, hybrid or modular kernel can significantly reduce this overhead while still being able to employ the same methods to amortize the cost that exists.

A microkernel is by nature incapable of being more efficient than a monolithic kernel. That is true as long as switching processes or going into priv has a non-zero cost.

The easy escape hatch is to allow a microkernel to run processes in priv ring and in the kernel address so the kernel doesn't have to switch out any page tables or switch privs any more than necessary while retaining the ability to somewhat control and isolate the module (with some PT trickery you can prevent the module from corrupting memory due to bugs or malware)

A fair question, I actually did install two different Linux distributions a couple weeks ago. For some background I'm a software developer, and consider myself reasonably competent in using Linux.

I started with Fedora. Installed, seemed nice. Then I did a dnf update or something like that. It froze for 4 hours in the middle of the install. So I hit ctrl+z. When I restarted my computer GRUB was attempting to boot an OS version that did not exist and I had to manually try to figure out how to fix this which I was in no mood to do after having the OS for 10 minutes. Also apparently the newest version of Fedora didn't have the concept of turning off auto lock? Or a timer. I'm not sure, but the end result was that if I tried to watch a movie for more than 10 minutes my desktop would helpfully lock, continuing to play the movie.

So I then installed Ubuntu, which was fairly straightforward. Then deleted the couple of things that felt like advertisements (like a direct link to Amazon on the quickbar or whatever it is). Overall, was a pretty good experience until I installed the proprietary Nvidia drivers. Then for some reasons movies (DRM-free files) would stutter. At that point I was thinking about doing some C# development in visual studio anyway so I looked into dual boot installing windows 10 while having Ubuntu installed, and while there are a million articles on how to install Ubuntu with Windows 10 already installed, the reverse did not seem to be true. So I just wiped my system drive and reinstalled Windows 10, which helpfully activated based on my hardware profile even though I'd neglected to save the key.

> Did Linux succeed because other UNIXes were bad?

No, it succeeded because there was a need for a UNIX like OS not encumbered by lawsuits (like BSDs) or costing a fortune (Solaris, SGI etc.).

Linux is a clean room implementation that doesn’t borrow any code from proprietary AT&T UNIX, ensuring that it has future. That, and the backing of FSF means it is not going to be sued into oblivion - something that could not be said for BSDs and other free variants back in 1990s. No one wants to invest into a something that may be shut down anytime. It is the fighting thtpat hurt the BSDs the most — causing them to be overshadowed by Linux despite being superior in many ways back in the days. Some would argue that they are still technologically superior in certain areas — but that is debatable.
I agree if the language is something very specific like SQL, or an extension language to embedded as plugins.

Otherwise any general purpose language, should be able to be used for all kinds of application, including compilers.
He basically identifies 3 free related issues coming to a nexus with FB. First is that free and monopoly (in the Pete Thiel sense) are related. A lot of the FB problems are problems of concentrated scale.

Second is the advertising business model. There as side effects to this three-way market. In any casefb as business works because they are such a monopoly.

Third is political influence, which I think is at the centre of FB's current heat, not data security. People become presidents on FB, revolutions happen on FB. This gives extra importance to the first two.

FB had been in denial about the politics issue, I suspect they still don't fully grasp it. They're not a neutral platform. They actually built in certain biases via their "optimization" for "engagement". In any case, since people like to argue politics on FB, it's a great advertiaing platform for politics.

I think they will not like the answer to the last problem. Its either an editorial approach, recognizing their position as a publication or trying to get rid of politics.
That's something most people think and do. The problem is that they assume that all this targeting will work in future as it is now.

My wild guess is it will not, it will get much clever, it will be able to figure out if a given person is "worth being targeted" (buys expensive goods and services and does this often, has big credit on his card, etc.).

Soon or later those who does not qualify will get nothing or will have to pay a lot to access given service since not being part of it will be considered suspicious (by government, employers, shops). US gov wants people to give their "social" username at the border, Chinese government is working on system to "rate" citizens, companies are setting the prizes in online stores on the base of knowledge they have about incoming customers.

Traversing a saying about communists and capitalists it seems that social networks are giving away a rope they will hang its users someday.
