> I am surprised no one mentioned that it is possible to trace bitcoin.

The many ways to CoinJoin that the article covers address just that. (Just saying for completeness.)

> this article make me wonder if its real value depends upon its use for illegal activities

Bitcoin has many values to many people. Speculation was most often at the top, money laundering / unsanctioned money transfers, drug trade, trafficking and similar non-speculative, criminal uses second. With the recent changes, speculation may come to have a smaller share than before, but still significant. Since the dream of STONKS was always what made the general population condone crypto currencies, maybe we’ll see a decline in support in western societies. At least, with the heavy AML effort in the EU, it could go that way. I sense that Asia is not going that way soon. From what I’ve read (I’m not in Asia), it is as hyped as it ever was. I suspect it fits with gambling cultures.
Yep, doctor just means teacher. A physician should be called medicus if they want a fancy Latin title.

> Pedagogy is about how children learn, it has less relevance in higher education, which is more about learning how to learn. Andragogy is how adults learn and I invite anyone to see how often that word is used.

It's always amusing to see lectures on correct usage from people who don't know the difference between etymology and meaning. (And also who don't know the etymology, either, since etymologically, pedagogy isn't “how children learn” but more like “the act of leading children”.)

In English, especially American English, “Andragogy” is mostly used in relation to a particular theory/approach to adult education originating with Martin Knowles, who leveraged the same conflation of etymology and meaning—even when it originated, pedagogy was well established with its modern and more general meaning despite the narrower sense of its Greek roots—to promote it; education for different audiences by age or other circumstance is not generally distinguished by different greek-root terms in English, but by English terms [“early childhood education”, “adult education”, “continuing professional education”, etc.)

Show HN: NetBird – A P2P Network with WebRTC, WireGuard, SSO, and Zero Trust
Hey folks! We have just released NetBird. It is a big update so I decided to share it here and get your feedback :)

NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, data center, container, cloud, or edge environments) unifying virtual private network management experience. It uses ICE protocol (WebRTC) to negotiate p2p connections and WireGuard (kernel module, when possible) to create a fast and encrypted tunnel between machines, falling back to relay (TURN) in case a p2p connection isn't possible. Pretty much just a client application installation is needed, the rest is done by the software!

Sharing the project with you wasn't the only purpose of the post. I wanted to discuss the future and vision behind it.
I'm pretty sure that in a few years, such seamless connectivity without the hassle of configuring firewalls, managing IPs, manual key rotations, centralized gateways, etc. will become a commodity and the majority won't be talking about traditional VPNs.

But what we think is becoming more relevant is advanced network security. We've seen the rise of Zero Trust with its ZTNA solutions in the past years. There are big vendors like ZScaler or Palo Alto already offering advanced network security features that leverage ML or contextual access controls to allow/block access based on context, not just identity.

Why can't this be open-source and built on top of universal connectivity that works anywhere? That is what we are setting as a mission for our project - to bring seamless connectivity and advanced network security together in a single open-source solution.
What do you think about it?

We welcome contributors and if your excited of what we are building, feel free to reach out to us!

P.S. We've been previously know as Wiretrustee :)

If latency is your main concern, switching your kernel to something like XanMod Real-Time [1] may be enough to fix any latency issues.

I think that's the big question isn't it? We're now at a point in human history where a few percentage points of annual growth, when compounded, can lead us into an extinction event/societal collapse. The big question of the 21st century is how long can this continue before we have to hit the brakes?

The closest thing I can think of is small family-owned ventures. Or on a larger scale perhaps the Cuban cigar industry? It remains labor intensive and is locked to a specific region which means growth prospects are limited. It also exists under a socialist regime so there's no incentive for growth.

If the DNS server of your local ISP maps rt.com into an IP address that it controls but for which the server has a certificate for a different domain, i.e. upc.biz, there is a conflict: your browser still has rt.com in the address bar (it is not a http redirect) but it sees a certificate for upc.biz, so it reports a certificate error.
I studied engineering in Italy and all my exams were both written (with exercises, multiple choice didn't exist at all) and oral. No way you could cheat or not engage with the materials.
Sylt ist fällich!
> I've personally never witnessed any cheating, heard any friends or
students even allude to doing so, I never cheated myself and I can't
even comprehend how you would cheat at most of the coursework I did
in uni in Sweden.

For most of my life I would've been frightened to even say so, or risk
accusations of being a "swot", "teachers pet" or as the Aussies call
it, "a tall poppy".

But the attitude that it's "normal" to cheat is common within
US/UK/AUS culture now. Truth is I always considered cheating beneath
me and was simply _WAY_ ahead of every class I ever took - but you
can't say that in "polite" US/UK culture - one cannot be too pious and
clean-cut, one must seem little bit like "everybody else" - even if
everybody else is not really like that, if that makes sense.

So actually I've taught at universities in Sweden (Stockholm) and
Finland (Helsinki) and notice similar attitudes to those you say. But
those cultures aren't without dirty hands either. Here's the weird
thing: Tall Poppy Syndrome is culturally closest to Jante Law [1], a
Scandinavian ethos of "Don't think you're better than anyone else"
which is precisely the corrosive culture that means people cheat
because everybody else is cheating and causes a downward spiral or
race to the bottom.

"When you've done your very best
When things turn out unpleasant

existed, but now I see it everywhere, not just in school.

> what is the point of privatizing something when the structure itself doesn't change and the privatization does nothing but siphon money out of the system and pump tax money in anyway?

That is the point.

Gigantic projects like nuclear reactors, stadiums, high ways, bridges, airports (hallo Berlin) trains (and big software projects and wars, too) are just different ways of funneling a significant percentage of the tax payer money funding the project into the politicians' and decision makers' circle's wallet.
> And yet correlation is not causation

Well... yeah. To pedantically elaborate that, clearly the hypothesis is that the measured traits (doing well on a coding interview and doing well at coding) are co-causal, and that measuring one (which is comparatively cheap to do) is a useful proxy for measuring the other (extremely expensive!).

That's a really compelling hypothesis. The counter point requires, to my eyes, a clear working example: a company with a uniform hiring process involving some other technique which has a track record of product development as robust as all the existing leaders. And I don't see one. Calling them monopolies or cargo cults seems to be filling in for evidence, and I don't see that as persuasive.

The age of the fast self-checkout lane is over
Sometimes I think this about huge swaths of human discourse. How we’ve formalized computation and think about it, large branches of philosophy going back to Plato and Aristotle.

For example, math has continued to be unreduced to any other theory. There is also no dogma of what counts as math. Is it what follows from intuitionism, from certain axioms (which axioms and why), from classical logical principles (LEM, LNC), from sentences which can be propositionalized or predicated, from psychology and physics? No one has demonstrated they have the answer.

Maybe we keep chasing the same rabbits too strongly. Especially since we don’t know how mind relates to world.

I'm not sure I understand your question. The point I was trying to make is that moving away from a growth-based economy is inevitable on a planet with finite resources. It doesn't mean we all need to live in mud puddles and eat slop.
How often does one need to convert miles into yards?

Of course I know about the SI base units, which effectively remove the ability of ordinary people to tinker with, use, and reason about measurements by placing the system in the hands of ultra-experts. Just consider what a diversity of miles used to be enjoyed by the world: https://en.wikipedia.org/wiki/Mile#Historical.

It is impossible to return to the pre-standardization days, and I do not argue that we should. Many people enjoy savoring the differences that other cultures provide in terms of architecture, cuisine, language, etc. and decry the destruction of cultural differences wrought by things like tourism, globalism, capitalism, whatever. I mourn the loss of local measurements just like I do the loss of vernacular languages, architectural styles, styles of dress, foods, all that.
Cooking can take a lot of time, but there are some tricks to make it more efficient.

1) Buy a large freezer. Then you can cook larger amounts, divide them into small boxes, and freeze them. That means you can have a cooked meal every day, without having to cook every day, or having to eat the same meal two days in a row.

A large freezer also allows you to buy ingredients when they are cheap, without having to consume them immediately. Peel them, cut them, freeze them. Later, take them out of the freezer and put them into boling water.

2) Be selective about the recipes. Some of them require 2 hours of work. Some of them only require 30 minutes, and 20 minutes of that is literally waiting. You can decide to only do the latter. And the waiting time can be spent doing something else.

3) While you cook, you can listen to a podcast or an audio book. Download some good stuff to your smartphone, or buy a wireless headset. Cooking for 2 hours can be fun, if you simultaneously listen to Joe Rogan.

An alternative is having someone to talk to. This may depend on how your house is organized. Sometimes the kitchen is at the opposite side from the living room; sometimes the two are connected. In the latter case, you can chat with someone while cooking.
Does work for me for Turkish airline operators (I tried TK and PC)
The other key feature of "serverless" is that the store-of-record for a "serverless" system isn't a part of the running system — i.e. the system's state doesn't live on any particular server / cluster that is run as part of the operations of the system.

Instead, a "serverless" system's store-of-record is some external and semantically-abstracted storage system — e.g. "a remote git repository" (GitOps); "an object-storage bucket" (Snowflake); "a document store" (Lambda); "a blockchain"; etc. Where all that's important about this storage system is its API, such that the design is portable to any backing storage service that supports the same API.

This means that, in serverless systems, the mutable state in the cluster is just an ephemeral cache representation of the externally-managed data-at-rest.

Another way to think about this is by thinking of "a server" as a thing with durable state that you have to worry about — e.g. protect from disk corruption, make backups of, etc; vs. something like "an ephemeral immutable-infrastructure container workload" that can die and be recreated with no problems. Serverless systems are systems without any "servers" in this sense — nothing to back up; nothing to disaster-recover; etc. Nobody operating these systems ever needs to think about individual servers. Nobody ever needs to SSH into a server, upgrade a server, restart a server, etc. The operations for such systems can be handled entirely at the "cluster" and "ephemeral workload" levels. Nodes within the cluster that "go bad" can simply be drained and deleted — this may even be automated.

And further, because of this lack of local durable state, there's no need to worry about "allocating" that state, and thereby allocating customers to particular clusters. Serverless compute clusters are usually just one huge cluster (per region), where customers' individual request workloads just get scheduled onto that cluster wherever they'll fit.

Of course, the external store-of-record for a serverless system must have "servers" — the data-at-rest ultimately has to reside durably on some disk somewhere. But 1. they're not your servers, and their ops problems are not your ops problems; and 2. because they're a much lower-level abstraction, they can scaled much more robustly, and so can have far fewer operational problems in the first place; and 3. because they're a much lower-level abstraction, they benefit from economies-of-scale in shared tenancy in ways domain-specific compute/DBMS/etc. clusters usually don't; and so your system can benefit from a storage layer that's hyperscaled + hyper-robust from serving millions of tenants' low-level needs.
Are you me? I have almost the exact same build as discussed in the post, and I am super annoyed with how loud the disks are. I have a cronjob that puts them to sleep every night(the NAS is in my bedroom)... For some weird reason they never stop spinning otherwise.
Okay, can you provide some literature on that claim? Do you, by any chance refer to the European governments buying directly from the pharma companies, thus getting solid discount? Or is it the case that European companies simply copy the drugs and move on? If that's the case, is the US healthcare expensive because pharma companies need to make money from the US sales only?
Sure, feel free to compare the trains in New York State vs Germany then.
> I was surprised how much of the throwaway news filler in Europe is about random Florida-man stuff.

I'd guess that that's mostly because the Joe from Florida is both far, far away (so they can publish unverifiable bullshit) but also culturally adjacent and his exploits or misfortune more relatable than, say, a guy from Uruguay or Vietnam. Also you wouldn't believe how many trash articles start with "American scientists".
Honestly, I would start by looking at an undergraduate physical chemistry book. Chemistry is just applied physics at the smallest non-quantum scale (mostly)

- you learn about thermodynamics
- introduction to basic concepts like heat, enthapy, entropy
- quantum light effects that explain absorbance, Raman scattering, fluorescence
> The majority of browsers that were commercially closed software didn’t make it

Keep in mind that the last time this was tried, free/open-source alternatives were on-par if not better and the web was much less hostile.

Nowadays, not only is the web teeming with hostility that can best be addressed by a browser, but the closest free/open-source solution (Firefox) is half-baked and doesn't actually solve many of these issues nor is it incentivized to due to murky funding (most of it comes from Google, a big advertising provider) and a dysfunctional company.

A browser whose funding comes directly from its users wouldn't have these misaligned incentives and wouldn't be afraid of doing bold moves that piss off adtech.

The Enterprise™ spends a lot of money on (often dubious) security products and given that the browser is often on the front-line for various threats, a browser with built-in security features (both against malware and other features such as DLP, blocking/filtering/monitoring without middleboxes) with a paid enterprise plan subsidizing a free version for personal use could become a sustainable business.

You can't ignore the details if you want the fastest performance. Unfortunately sometimes the solution that's the fastest is also more complex. Simplicity tends to win and also is less likely to be buggy, easier to maintain etc but sometimes the fastest code deliberately introduces coupling, hardware specific cache shenanigans or unreadable hand written asm and/or inlined SIMD. This is often counter to your hypothesis.

> A great example on why 'trust' only works for everything inside the Blockchain only.

Having a “trustless” component at the core of a Blockchain has made us all re-examine the places where we deeply rely on trust for real interaction. It is ironic how “trustless” technology is so apt for scamming if you can trigger peoples desire for wealth at the same time. “You don’t have to trust me” was always a great bait for a victim who takes trust for granted. You just need to say high numbers and people will wire money to you.

Cuba's data is pretty suspect. Too lazy to find it at the moment, but I recall reading that their cancer rates or deaths were some absurd fraction of what would be expected given smoking rates even compared with better developed countries. They also had some eye raising way of counting perinatal infant death that makes their infant mortality rates look a lot lower.
