She didn't eat donuts and fries, true. She was born in 1926 in rural eastern Slovakia, so her staples were meat (including cheap, highly processed meat), local variant of pasta (halušky), plus a lot of animal fat.

Her cholesterol was something like 9,5, often exceeding 10. She also smoked for 30 years, but stopped around 65 years of age.

Theoretically, her arteries should have been clogged like crazy. They weren't.
Thanks for explaining! (I'm a different person)

I can understand why this gives a better learning experience and results (for most students). Hmm, also depends on the subject -- they're saying and discussing things? Eg social sciences? Whilst in maths, maybe there is less to discuss and talk about, and the positive effects you're seeing wouldn't be there?

Seems to me all this can be done in real life too -- but requires more discipline, since the "default", that the more talkative students speak out loud when they want, is what comes naturally? Rather than writing questions and thoughts on paper and handing in, and you read them.

Would be interesting to try IRL with pencils and paper :-) I'm not a teacher though.

Edit: what do you teach? / What do the students study
Don't sell illegal drugs?

Sure there are countries with no functioning legal systems and extreme levels of corruption but most people affected by that would probably have a hard time using blockchain technologies directly and would have to rely on 3rd parties anyway.

When you use bitcoin, you actually rely on a third party to validate your transaction. A banking organisation can also be a third party.

> Consider the complete graph on n vertices; there are roughly n-factorial-many Hamiltonian cycles. Any permutation of the vertices corresponds to one such cycle. Different permutations can correspond to the same cycle, so the number is not exactly n-factorial.

Isn't it just (n-1)!/2 as each cycle can be cyclically permuted (n possibilities) and (for n>=3) also be reversed? (Cases n=2 and n=1 have only one cycle.)

(That wasn't the point you were trying to get to, I know. I'm just thinking about the precise number.)
I'd go one step further: the few legal purchases done with crypto currencies are mostly done by people unaware they're paying that price
If you’re transacting with a bunch of people that you do not trust then the payment rails are the least of your problems.

Your comment just feels like typical crypto-booster vague handwaving to me - can you give an actual example of such a situation where the existing third parties that alreayd exist to solve these kind of problems cannot be used? Be concrete.
Proof of Work is only as good as the assumption that CPU power and energy are guaranteed to be equally distributed, also everyone must have equal access on the network. Which we've seen is not the case.
This is enraging. Would you please be willing to countersue HackerRank on behalf of:

(1) abusing the DMCA
(2) lying in the DMCA message

I want that HackerRank is made an example and that this sets a precedent for all other DMCA trolls. Please follow through with this for all other open source projects that can be targeted the same way.
Absolutely not.

Proposing that just because something mimics something then it equates it is so absurd.
I cannot judge the American banking situation but I can attest to the fact that transactions are reverted constantly in Europe. The reason for this is the SEPA direct debit system where debitors can directly charge an account via SEPA direct debit and fraud does happen. For that reason banks are very happy to reverse the transaction and it's not at all a unique situation.

US Army plan to replace Patriot interceptors gets a jolt in FY23 budget request
This is true, but that was also the case for Russia in Afghanistan, or the US in Vietnam, Afghanistan, and Iraq.

It's hard to tell what Russia's goals really are because on one hand they say "we just want the Russians in Donetsk and Luhansk to be free", and on the other hand Putin is also openly saying Ukraine isn't really an independent country. Besides, Kyiv isn't in Donetsk or Luhansk is it? Maybe Putin's map is wrong.

Even if they managed to complete their military goals this week by defeating the Ukrainian armed forces and toppling the Ukrainian government they will either have to retreat and leave Ukraine independent with extremely hostile views towards Russia (and will probably try to join NATO/EU), or they will have to occupy an extremely hostile population who feel their country is invaded by a hostile malevolent power.

It seems to me that Russia already lost, no matter what happens militarily; they dug themselves into a pit that will be very hard to climb out of. The biggest question is how much (more) Ukraine will lose in all of this.
I think your question is too general to answer effectively. In theory just about any data structure can be implemented on disk but in practice access times are likely to be too slow for that to be a usable solution in most cases. As far as I know databases typically use a few specific data structures which are optimized for this sort of application, such as B-trees.

Terabytes of data for a decision tree ? I've heard of deep learning models with billions of parameters but I find it surprising that you would need anywhere near that much storage for a decision tree.

EDIT: Moreover if you do need that much storage, you are almost certainly going to need multiple nodes to process that data reasonably quickly so you would almost certainly need a way to partition the dataset across nodes rather than having everything stored in a single file. The company probably most known for developing that kind of architecture is Google and I think there is a fair amount of information available online on their architecture. That might be a good place to look to get you started.

EDIT2: And how would you create such a large decision tree in the first place ? Are you sure that's the best type of model for your problem ? It seems to me it would likely massively overfit just about any dataset you trained it on.
Same reason game developers get treated like shit compared to many other developers. People are willing to put up with more shit to do a job they find rewarding.
New Test Compares AI Reasoning with Human Thinking
> I don't think protection against human-factor scams and frauds was ever a goal, you certainly never hear it as an argument.

In a sense, it admits that traditional banking has the advantage in that regard because it has things like traceability, reversibility, insurance, accountability, and legal guarantees. These have been put aside on purpose in the crypto market, and while I think I understand the whys and wherefores, I don't see giving up these consumer protections is worth it.

Well, not to me anyway, but I'm not getting rich off of crypto.
I like these articles as they will probably bring blockchain to a better state

Even if we all know knifes are dangerous

Probably in the future most enterprise applications will have some sort of transaction blockchain for auditing
I would look for some local hackerspaces. They usually come with a space for electronics, and at least where I live (tho space is not so premium here), you get a key to access the space whenever, if you are a member.

Alternatively, you might have some luck contacting a local university, they might be open to let you use their lab (again, probably for a fee).
This is a heck of a lot of hard work. I wouldn't dare to call this passive by any means. You're going to spend just as much time updating content when technologies become obsolete or outdated as you did writing original material. This is hard hard work that's paid off. Major props to the OP, but there is nothing passive here.
I mean when you put it that way, blockchains aren't really financial systems in the first place.
I've laid out how they are linked. Please debate my points rather than saying it's a fallacy, which adds nothing to the conversation and is basically an ad hominem attack like this (see, I can use these debating words too!)
> technology does not solve technical problems that havent been solved better

Critics like Diehl repeat this often, but without ever referencing the solutions. What non-blockchain solution solves the double spend problem when transferring digital assets in a peer-to-peer network? Or, in the case of Ethereum, providing solutions to general-purpose decentralized computation and state (rather than only peer-to-peer payments) with such strong public consensus?

I would love to see the following succinctly solved by a non-crypto and non-blockchain solution:

- User A holds digital asset X (such as a valuable domain name "xyz.eth") and User B holds digital asset Y (such as a valuable sum of stablecoin tokens) and these users wish to exchange them in a single public + cryptographically verifiable transaction (i.e. atomic swap), without relying on the trust (and for-profit services) of a third-party escrow agent.
The basic definition of a blockchain covers the implementation of git.

I guess, as the question/answer implies, ultimately, it's personal opinion.

I look at Git and other DVCSs implementations and see that they match the definition of blockchain.

> A blockchain is a growing list of records, called blocks, that are securely linked together using cryptography.[1][2][3][4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leafs).

How so? So far, crypto seems to amplify its worst trait: greed. It takes its destructive properties to new levels.

These controls are there for a reason. Controls create trust, and trust removes friction. Creating a stable currency and protecting people's money from scammers has nothing to do with censoring speech. It's a false equivalence.

You also get this in an environment where the slightest mishap can irreversibly empty your savings account.

That's a problem with capital, not the currency with which it's expressed.
I'm not sure I fully understand what Lennart means by "/usr merge". Is it assuming all paths under /usr belong to the same mount point, or something else?
There's a pretty hilarious split in the comments which I think is due to time zone. Americans think the project is cool because self-promotion is valued there. Europeans think it's narcissistic and self-absorbed.

I think it's in between. You have to be a pretty self-absorbed person to start doing this, but then I think it organically grows even bigger over time, and then becomes cool enough to actually show other people.
Honestly, I'm a little sad about PHP's direction. What I enjoyed most about it was it's simplicity. It seems like at this point everyone is trying to add $everything_i_like_about_java and $everything_i_like_about_javascript etc. It's almost like this is "phpng" now.

I've always dreamt of a purely procedural PHP fork, removing all the overhead for object management. Keep things as functions, arrays, and I'm even cool with type juggling. Fix the needle/haystack stuff, but basically a "scripting" layer relatively close to being on top of C, in a way. I can do a ton of amazing things without the need of OOP/objects/autoloaders and basically anything else introduced after PHP 5.x. :)

> I don't buy your claim that an educated (implying literate) person would not understand the idea of storage of information.

I agree they'd understand we can store information in written documents, etc. But I don't see why they'd make the leap from information can be stored somewhere to all information must be stored somewhere. The later is a modern view rather than an ancient/mediaeval one. But, absent the belief that all information must be stored somewhere, my hypothetical disembodied mind has no reason to assume its own thoughts/memories/etc must be stored somewhere.

> Keeping BBs from appearing practically everywhere in the universe turns out to strongly limit a number of features of the not-full-of-false-brains universe we appear to inhabit

I think BB arguments are dubious, because they all involve disputable philosophical assumptions (about the nature of consciousness/etc). If you subtract those philosophical assumptions, BB arguments no longer work as justifications for rejecting those physics theories which produce "too many" BBs. Also: if combining a philosophical assumption with a scientific theory produces absurdity, why treat that as an argument against the scientific theory, when instead you could use it as an argument against the philosophical assumption?

I have my whole system running like a livecd using overlayfs, it's great. It's a real peace of mind knowing nothing will persist. No logs or information is stored without your knowledge, any configuration mistakes will solve themselves on reboot, it also enforces the separation between your data and the system install.

At the start of the post you were the person taking out the loan but by the time you got to the explanation at the bottom of the post you were the bank.

If you've sold your $2/year income for $100 yesterday, why on earth do you want to buy it back and resell it for $50?

e: Oh wait I see. You want to go to the bank and say "I know I owe you $100+interest over the life of the mortgage, but what if I just pay you back $50 right now and we call it even?" Does that actually work?
Compare romance scams, authorise push payment fraud, and ponzi schemes.

You can absolutely have a 30 year mortgage that is fixed all the way through. It's rare that people take it though, most opt to 5-10 years fixed with variable late afterwards from my own experience (Austria). The standard product used to be fixed rate.
My suggestion is: "grow up".

All of human society is based on trust, and it works just fine and has for centuries.

Who would even want to live in a trust less society? That sounds like hell.
>better housing technology

Almost everywhere throughout the developed world the ratio "house prices"/"wages" is skyrocketing. Young people are increasingly forming a precariat with fewer and fewer of them being able to own a home and constitute a family. "Better housing technology" what does this even mean? Solar panels on the roof? Well first you need to own a roof to put panels in.

>better food technology

Obesity is increasing. In most places junk food is cheaper per calorie than healthy food (to say nothing of aggressive marketing of the former). Again, what does this "better food technology" refer to?

No, Proof of Work does not need to be equally distributed. Even if just one entity does all the work it is incentivized that its blocks are accepted by the community otherwise all the work was for nothing and the miner makes a loss.
I’ve been both on the deploying side and the consuming side of VDI solutions in both commercial and educational settings. My experiences with it have universally sucked.

There’s almost always a problem with capacity planning, especially around peak usage, that almost always results in a shitty experience for the end user. VDI gets touted as a cost saving solution but whatever you save on hardware you get back tenfold in frustrated users and support needs. And you still need to administer and maintain the end user terminals anyway which isn’t significantly less time consuming than a fleet of standardised workstations.

As a consumer, it’s always terrible. Performance is disappointing, anything graphical is a nightmare. If the network is down or congested you can’t work, despite the fact that all you need to do is edit a Word doc.

At a newspaper I worked at we ended up with VDI for most folks but editors had both VDI and a local workstation. Some software could only be accessed in one environment and not the other, so there was a whole dance you had to do to move work across too. It was a nightmare and costs were ridiculous since we ended up managing two environments anyway.

I’m sure VDI can be done well in some environments. I’ve just never seen it be better, cheaper and with less maintenance and support burden than a managed fleet of workstations/laptops.
For me "quantified self" has been half meditative. I have tracked daily water intake (and only water to keep it simple) and that has been a huge noticeable quality of life improvement. Waterminder on apple watch is the best.

This year I added in daily mood tracking, and it's mostly focused on taking 5 minutes a day for myself to just jot notes down quickly. I'm using dailo and I have a few categories too (work good/ok/bad - food homecooked/takeout - vices) and just the space I've created to do that has been worth it. I don't expect to get anything too interesting long term besides patterns in takeout/cooking, but I find myself more connected to my day good or bad, and that presence of mind to combat the autopilot is worth it.

Danish loans are a bit special, though, as in most people don't pay them down, but just use them as a way of having a fixed rent. At least that's my experience, all my danish family own their houses, but have almost done no real payments on the loans. Whenever they've paid down a bit, that is just refinanced to a new loan so they get cash, aggressively promoted by the banks. Or the equity is just based on a hope that the loan will stay the same but the value of the property increase. Which it certainly has not.

Nirvana fallacy. Bitcoin allows people to control their own money, if they decide to give it to scammers, it's not Bitcoins fault.

> The absolutely perverted energy usage in times of climate change is only one of those (this is mainly caused by proof-of-work, still used by all relevant public blockchains, and general inefficiency). [8]

Bitcoin provides truly self-custodial, borderless money to the world and only causes <0.1% of CO2. Crypto donations to Ukraine worked flawlessly in the current time of war in which national banks are not fully operational. Refugees are able to travel with their funds simply by remembering a few words.

I would not call that "perverted energy usage".

Video streaming, video games, porn, dryers are causing similar or higher CO2 emissions. Wasted foods alone cause 6% of CO2. Calling these emissions useful but at the same time denying unbanked people access to financial services reeks of financial privilege.

Also the cited source [8] is an employee of the dutch central bank which is probably as opposed to Bitcoin and cryptocurrency as you can possibly get.

The rest of the article cites several projects which use the blockchain label to generate publicity. While this criticism is warranted, it should be directed at the projects, not at blockchain tech in general.
the binaries are not specially lightweight either. What I had in mind in that when you start CL or install a bunch of dependencies (by staying in the REPL), this doesn't take many resources. Try another modern Lisp and bam, CPU and memory on fire. Running a binary is instantaneous too. That's a smooth developer experience.
