Ask HN: Project Based Tutorials?
Getting back into web dev after a multi-year hiatus so I can build some project ideas I've been wanting to tackle.
For now I've chosen a stack including react, node, tailwind, etc.

All the tutorials/guides online seem to regurgitate official documentation, are super outdated or are very basic.

I know the best way to learn is by building something (which I am doing) but I feel like I need a little bit more experience seeing how other people build things, tinkering around with their solutions and seeing how something is made from start to finish.

There's just so much stuff out there now.

I'm a huge fan of www.fullstackopen.com, are there any other project-based tutorials you guys can recommend?
> Did you know you can get a public URL for a Node application being served from localhost or 127.0.0.1 on your local machine, even if its behind a firewall or corporate network?

Great way to irritate your security team.
Personally I’d like to see a return of mandatory draft or civil service. I think merging people across all boundaries to forge common experience could only serve to improve society.
To start you Tweet off chain, and you only verify on chain. Most of the skeptics here seem to take pride in their shallow understanding of blockchain - most of these questions are posed with some idea that people want to post a million tweets a day on the Bitcoin blockchain. People smart enough to answer your questions don't actually hang out here - I would know, because I hang out with them where they are welcome.

And yes, those people also make a distinction between themselves and the average grifter - something HN fails miserably at.
Yes I've called my Representatives I get someone answering the phone that says they'll take my concern or suggestion and that is the end. If you want to have a meeting with them then you have to pay for it and you usually need to draft the changes to the bills in advance if you want them introduced which takes entire teams to do, but even individuals can see where things are clearly wrong. The only special people in politics are the ones who pay and have money. Everyone else is just hoping they'll get a share of the pie in the end.
Apps Script is amazing and a sorely under-appreciated feature in Workspace.
You can always use an ORM which provides better usability for developers.
End of the day rdbms model is suited for a wide variety of workloads and there are several other factors in play while choosing a good db including eco system, cloud vendor support, migrations, performance etc.
For most people.

For many professional digital artists and designers, however, the iPad is far more convenient that the traditional Wacom tablet connected to a desktop or laptop.
I've been intrigued by dgraph (https://dgraph.io) and used it to good effect in a (toy) project where it felt easy to create and evolve it's data model given changing requirements.

Dgraph uses graphql as its native query language.

Anyone here has some experience to share on it? ... Since it isn't mentioned in the article.
In the process of functional modification of the backup program by Hewlett-Packard Japan, the supplier of the supercomputer system, there was a problem in the unintentional modification of the program and its application procedure, which caused a malfunction in the process of deleting the files under the /LARGE0 directory instead of deleting the backup log files that are no longer needed.

Use a real debugger instead of printing variables

"Print real variables instead of using a debugger"
The narrative driving Web3 is that people don't want to be treated like cattle. Or in your parlance, "the average user." Just because people are slow to wake with the contracts they made with centralized platforms doesn't mean they are so dull as to not care when they finally figure it out.
Beanie Babies, Baseball Cards, Comic Books all had period of rampant speculation whos markets were destroyed once people who "invested" tried to turn their assets back into cash. Hobbyists just suffer through these periods.

Anecdote time, I was at an Xmas party and people were talking about what crypto they were investing in. I said I speculated a bit, then got spooked and got my money out of Crypto.com. (which wasn't easy). This got everyone interested, they had no idea how to turn their Crypto back to dollars. The market is going up, because there's a one way flow of money.
People can question the science all they want. But when you do, you need good, verifiable evidence to back your claim or else you won't be taken seriously.

And if you contradict health science without evidence, you're impossible to differentiate from someone spreading dangerous lies that will cost other people their health and lives. That's where the law comes in to stop you in order to protect other people. Without it, we'd be back to snake oil merchants.

This whole discussion reminds me of Reddit's imfamous /r/findbostonbombers. Humans seem to have this need to find and punish cheaters (see for example some of the experiments by Cosmides and Tooby). Sometimes we get things wrong.

(we did it HN! Take that lamestrean media)

This seems like a pretty low-level detail that doesn't warrant being heralded as a "breakthrough." They apparently have a new, more efficient power electronics to supply electric current to the superconducting coils. The electronics are situated inside the cryostat, so they are also cooled to very low temperatures apparently (few degrees Kelvin). The article is really vague, though.
You can also spend money and get a star named after you. I suppose you could assign an NFT to the stellar coordinates and sell the stars as well.
Every ycombinator project involved with the creation, moderation, infrastructure, management, or sourcing of content for platforms makes use of hn as a source. Everyone in those circles follow suit, HN is beautifully curated and wonderfully crafted to be open.

HN content is "fresh," mirrored on dozens of sites within minutes of showing up on the front page. 4chan and reddit get the links within about 20 minutes of it showing up here. Slashdot, dailydot, and other aggregators lag about an hour. Within 3 hours, most links here have probably hit the eyeballs of at least a few hundred million people, and there's probably a good 50k legitimately insane people in that crowd.

I found HN when I started looking for where the aggregators and forums were sourcing stuff I was interested in. I'd love to see Google's rankings and see what other sites are similar to HN in this regard.
It seems to me that it's comparing apples and oranges. I use Instagram because everybody else uses Instagram. I use Flickr, because I'm into photography and I don't mean Iphone or Android photography. I mean photography in general.

Instagram is a mobile app. End of story. There is some web/desktop whatever, but it's a joke. I do most of the image manipulation on my laptop/desktop, so I want something that works there. I want to share a full sized result, not a 1080px preview. Mobile app is a welcomed bonus.

Instagram is not a site for photographers. It's an image centric social network. Photographers can use it to reach wider audience, but besides that it has zero features geared towards photography as such. It works for exactly 3 (yes, three!) image sizes and doesn't even show EXIF data.
People made good money selling Beanie Babies, Baseball Cards and other fads... at the beginning of those.
Maybe it took the first failed project to realize that should the project succeed, there could be a financial incentive to kidnap/coerce/blackmail the founder.
Can you describe a monad without using the words "functor", "applicative," "endofunctor" or using Haskel syntax to describe it?
This is the kind of thing that inspires true Web3 people (not the grifters selling their OpenSea NFTs). If you dig into the problems that arise when implementing those systems you talk about and what happens when data of value can be contributed, you start naturally running into the solutions that Blockchain developers have been working on for years.
The Church of Satan was on the right track in some areas (such as viewing Abrahamic God as evil and nonexistent), but in others it is clear that it is an incoherent "first attempt" with lots of contradictory statements, such as the belief in magic yet the disbelief in Satan, and its hatred of abortion despite its otherwise Social Darwinist leanings. More damning (no pun intended) is how the Satanic Bible (LaVey's work) simultaneously condemns the authority of "God" yet says that dictators are good Satanists. It was very much the views of a single man, Anton LaVey, which while not entirely without merit and LaVey not being necessarily a completely terrible person, are far off course in my view in many ways.

Anton loved Ayn Rand. Many TST members are appalled at Rand's ethical ideology, or lack thereof, myself especially included.

You'll find that in many areas, The Satanic Temple is diametrically opposed, and represents a much more coherent, logical, refined ideology, and wholly rejects social darwinism as mostly discredited, advocating instead for empathy and compassion, recognizing their evolutionary benefit.

What both organizations have in common is the demand for rationalist thinking, the belief in the immorality of God, the belief in personal freedom, and deriving their ideologies partly from the sciences of their respective time periods.
I’ve used to this for distributed locking on jobs and it’s been great. The other janky implementation (without some distributed locks or task manager) would be incrementAndGet with a TTL. Obviously this runs into a lot more edge cases.
Related tidbit: Brad Bird (Iron Giant, Incredibles, MI:Ghost Protocol) was trying for years to make a related movie with this story as the context. The latest news is it was shelved 9 years ago after going through several screenplays and over a $200 million budget.
Though you acknowledged the bias against non native English speakers, I feel that’s a huge bias. I for one can write two pages comment on Reddit without thinking, but I never dare to so on HN. I feel the pressure to be succinct on HN and being a non-English, that’s not easy. And it’s not (primarily) because of vocabulary.
Be nice if you didn't actually have a phone number and you exchanged cryptographic keys with someone touchlessly when you were in physical contact. Then you'd have two-way ID verification, and if a merchant abused that by leaking their key material (or if it leaked in a hack) you could revoke that key's permission.

A large weakness with existing communication systems (phone, e-mail, physical mail) is that its a pipe where anyone in the world can blast at you, often anonymously.
Let's assume that Ethereum gets properly sharded, and web3 solves all these technical challenges somehow, because that's supposedly where Ethereum is headed.

Why would I as a user prefer Twitter or prefer web3 decentralized microblogging?

With Twitter, even with minimal gate keeping, I still get a spam/scam message only once every month or so.

But minimal gatekeeping is soooooo much better than email, where I get so much spam email that it has made the service worthless without spam filtering, which has an error rate for finding spam.I literally only read my personal email messages once every week or so because it's such a chore to get through all the craft spam, much of it from places where I once bought a single item.

So as a programmer and creator, sure, you prefer the ability to not be locked out. But as a user of Twitter, I vastly prefer all those programmers being locked from access. It's the only thing that keeps it sane and almost-useful.

One application I recently heard of that might be relevant: using wallets as crypto for the average person, finally allowing more secure and better website login. If everybody has wallet, it might finally solve the problem of scattered passwords everywhere for every site, with many users reusing site password.
Baseball cards now have value, in the period of 1990 to 2000 they were pretty worthless after the bubble of the late 80s crashed. They retain value though nostalgia, as soon as they become an investment again, and speculation starts, a new bubble will build, with a crash following.
Or, you could try to be nicer when somebody makes themselves vulnerable to you.
Yeah, why would anyone want an app like Facebook or Discord or Skype or Teams or Google Meet or Zoom or the littany of other apps that have some version of the functionality you just described?
This is not outrageous, very possible
I invite you to ask your child how he would share three cookies with you. I've been asking variations of that question to all three of my children since they could talk.

Of interesting mathematical consequence, each of my children converged on the same solution at different ages. Them: three cookies. Daddy: zero cookies.
Well, it should work in some well-controlled cases and in those cases if you're writing this code you are probably an OS vendor. Examples of legit use case: an executable loader or some bootstrapping code/bootloader.

When writing code like this, as Chen says, you are bound to the architectural rules regarding how to appropriately locate code and safely invalidate code caches etc.

So if you follow the rules it doesn't work then typically I figure you'd take it up with the CPU vendor.

While you could potentially do it and have a good reason to in userspace code, it should be heavily scrutinized because it's so unconventional.
I’m not sure how you arrived at that conclusion. If you go to the very beginning I’m sure many startups get money from employee #1, AKA the founder. But even in an early stage startup why hire someone that isn’t delivering value?
> The article just happens to use a photo of Mayer because she was the CEO at the time Flickr was sold to SmugMug.

Wait, isn't that just another way of saying that she sold Flicker to SmugMug? If so, she sounds very blamable.
So indelicately put.. Comes across (to my Euro mind) as an order doubled with an insult.

Looks like it is just more tailored to your particular brain neurocircuitry and give more pulses but instead of in 1 session over ten small sessions in a day. Sounds like it only makes sense that this works even better!
> We in security like to throw around that "once the attacker has physical access it's game over", but that isn't true in practice, as evidenced by the success of locked platforms like iPhones.

People find iPhone jailbreaks all the time. Apple patches them, but if you want a jailbroken iPhone, they exist.

Moreover, the vulnerabilities they keep finding were there before they find them, and the ones they'll find tomorrow are there right now, if you have the resources to look.

And this is distinct from the level of resources (generally considered impractical for anyone) for other forms of computer security, e.g. AES replaced 3DES in 2001 but still to my knowledge nobody -- not even the NSA or other state actors -- has ever even broken 3DES.

If you ask whether a large corporation could break into an iPhone today given physical access, the answer is going to be yes. And without decapsulating your CPU. The physical vulnerabilities often end up being related to USB and things like that.

Remember the whole farce where the FBI wanted to get into some iPhone and "couldn't" because Apple refused to help them? Then they just paid somebody to break into it.

> You can be secure against physical access, at least assuming your attacker can't decapsulate your CPU, rewire it with a FIB workstation, and recapsulate it

Or steal your phone and leave you with an identical looking one that transmits your authentication to the real one as soon as you try to unlock it.

And that's really the physical access problem. If you have a device with full disk encryption and have cleared the keys from memory, the attacker might not be able to get the contents even with physical access. But if they've had physical access and then return the device to you, can you still trust it? Nope.
> But at what point do we qualify something/someone as “smart”?

That's a good point. We can only give our guess based on what we know. For example, people regarded Alan Greenspan as "smart" before 2008. I now think he is an idiot at best and a horrible, malicious person at worst (the truth is probably somewhere in between). Maybe things will change in a few decades and people will then recognize him as "smart" again? It is pretty silly trying to predict the future.

> I’d argue that someone that’s getting lucky over and over again are clearly on to something. As the saying goes: “You create your own luck”.

I present Sir Isaac Newton as a counterexample. Clearly a smart person but just because someone is smart does not mean he was right about everything. In fact, we know now that his nonsensical "work" with alchemy killed him. I am positive that this fad will fail. I am just annoyed that now the name web3 is taken by this nonsense.
Oh I thought it was a marketplace.

Salaries aren’t high in the bay because houses are expensive. Houses are expensive because salaries are high. There happens to be a concentration of talented and highly compensated people there. That doesn’t mean they will settle for less elsewhere.
You bought a NFT on some blockchain that exists now, you didn't buy the number. I can sell that same number to someone else, and I could print a big picture of it on fancy paper in a nice frame and afix a hologram seal of authenticity. You owning the NFT of that number doesn't give you any rights to that sale, just as my framed picture doesn't give me any rights over the NFT.
They did get in trouble after all. https://montreal.ctvnews.ca/mobile/canada-post-s-english-onl...
The paper said that villages in Bangladesh that used the provided cloth masks did not have a statistically significant reduction in cases. This is not the same as saying cloth masks do not work; a cloth mask with higher filtration efficiency than was used in the study can be manufactured, but this was cost prohibitive compared to surgical masks. It was also not possible to procure one of the materials they wanted to use in the cloth masks; without it efficiency was only 37% instead of 60%. This was described in some detail in Appendix F.
This should be called ring -1 access. Or maybe -2 since IME is a thing sometimes.
What was the technology stack?
Sure. And everyone is welcome to go out and perform an intensive literature review of the existing science, make observations, come up with a theory that better fits the data, construct a specific hypothesis, run well-designed experiments, use statistically valid techniques to analyze the results of said experiments, and then publish their findings to be peer reviewed. That is (approximately) how you "question science."

What you don't get to do, and then claim that you're not being allowed to "question science", is "research" by watching random Youtube conspiracy theory videos, ignore the entire existing body of knowledge in a field, use dubious (or no) statistical analyses, and run around screaming on Facebook and Twitter how your "findings" about the dangers of vaccines, or the veracity of the moon landings reports, etc. are being "suppressed" or whatever bullshit you can think of.
If you are homeless, unemployed and unable to be employed due to mental health issues, anything more than “free” is too much for you to afford.

Those were the people I’m speaking about, those are people that many of us see daily, and those are a large portion of the homeless wrecking havoc.
Not saying this is evidence for or against it, but it shouldn't surprise anyone that someone who wants to stay anonymous would throw out red herrings.
Wouldn't it be easier if they just not interview anyone with more than X years of work history?
When the target of your objectively reasonable directive is self-admittedly of the mindset "I could (A) get up and do it, or (B) kill myself", you may want to reconsider the wording.
I think you have it backwards. Nobody needs evidence to doubt a claim, the burden of proof is on the claimant. There is a wide divide between doubt and "spreading dangerous lies".

I chose int16 just to make it easier to write an exhaustive search. That is where my assertion that the code works correctly comes from.

The case you suppose makes sense, but for some reason does not produce incorrect results when I run it, for instance:

N = INT16_MAX - 2:
mod(32762, 32765) = 32762
mod(32763, 32765) = 32763
mod(32764, 32765) = 32764
mod(32765, 32765) = 0
mod(32766, 32765) = 1
mod(32767, 32765) = 2

I wonder if the compiler just used the full register. I'll have to check the disassembly.
You may not want to hear this, but technical analysis of /price data/ is a fools errand for a number of reasons. There are the folks with PhDs who dream in C++ about martingales but even they dont consistently beat the index. More fundamentally, as a retail investor, you cant get better arbitrage than the pros can since they know 10x more than you do (I dont believe that the protections and firewalls between banking and broking are anything more than useful fictions, which means brokers and market makers always know more than you do).

I do think it is worth using technical skills to audit non price data however. Much less sexy but more valuable. P/E, FCF and all that.
WR for 40L is 14.9 by Reset[1] last I heard. 15 is definitely humanly possible.

Thanks everyone for the upvotes, I'd love to hear what you think.
A carrington event could do it...lots of estimates at 2 years to recover from one....

2 years without a supply chain, grocery stores, etc... of course that would equally affect our enemies abroad.

If any enemy abroad did it...we'd probably be ready to surrender in a month if they just provide food and supplies for the 3rd world country that used to be America.
I'm creating an NFT project that's doing something I've never really seen other projects doing in any capacity, and can confirm it's pretty hard doing something against the current perception of what is possible with the tech. It's been disheartening sometimes tbh because of the stigma the tech has currently, and I've been called a scammer more than a few times simply because I'm creating a project that utilizes NFTs, by people who only know of the current "link to png on cloud storage and nothing else" model that is most common.

Oh well, I just hope that when I release my project next month that I can prove that it's an incredibly unique experience that some group of people find it to be an exciting product.
i’ve very rarely found that using a full temporal table is the right choice for online analysis—a dedicated schema serves you better in the long run and helps you design your indexes, etc appropriately. For compliance, PIT backups via WAL shipping should suffice, no?
