Author here, this is a refactoring of qr-filetransfer, already discussed in the past [0].

Here's how it works: qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete. When used to receive files, qrcp serves an upload page and handles the transfer.

The tool prints a QR code that encodes the text:

http://{address}:{port}/{random_path}

Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser.

To send one or more files (or directories):

qrcp /path/to/file
# Or
qrcp send /path/to/file

To receive one or more files:

qrcp receive --output ~/Downloads

But if you have a large (hundred GB, for example) SLC/TLC cache and DRAM, then for most consumer use you're never going to see a difference.
I always get a bit conflicted with Marc Andreessen stuff.

Like this article starts out with a bold claim that's...wrong.

Germany have done well. A western country has done well. Elephant in the room, massive 80 million person country, major western power, and the American claims no-one's done a good job because the US hasn't.

And then he goes into talking about having pre-prepared therapies or a vaccine. Again, we already have to an extent. You can't make a vaccine before the virus exists, but you can have a way of rapidly making one. We do have pre-prepared vaccines, like this one:

Perhaps, again, he's just talking about the US?
Yes. Decentralized finance is coming and it's maybe the most important technology of the 21st century. If you want anything resembling autonomy and liberty in the future, and if you want to avoid ending up in a world straight out of a Black Mirror episode, I recommend supporting open-source monetary blockchain systems like Bitcoin and Ethereum. There will be an attempt at some point by governments to centralize blockchain technology. China is already doing this. Western societies should embrace freedom and openness in finance. Besides being aligned with our core principles, it's incredibly powerful, and it can power the capital infrastructure in very innovative ways if we let it.

To your point, cryptocurrency enables reconstructing the entire financial infrastructure on blockchain. Everything from car loans (https://twitter.com/DMMDAO) to rental real estate (https://twitter.com/RealTPlatform) to interest-bearing savings accounts (https://compound.finance/) to derivatives and trading (https://www.synthetix.io/), to decentralized storage (https://sia.tech/), etc. There's hundreds of projects I follow regularly and I find new ones cropping up all the time. There's a Cambrian explosion of apps in blockchain right now.

I recommend reading https://bankless.substack.com/ and https://thedefiant.substack.com/ to stay on top of the topic. Watch some of the presentations from ETHDenver 2020 that was held 2 months ago (https://www.youtube.com/channel/UCgz9NU06t_FkT0Py1Vadczw)

Follow some of the thought leaders on Twitter, et al. Tons of promise in this space.
They both out of the chart!
I shall never stop being bitter, as opposite happened to me. In primary school i possibly got the worst math teacher in existence.

Even since preschool i could do math in my head beyond my grade(3 years ahead according to psych tests that we all had to undertake), and all of that was killed by a single teacher who had me under her care for 3 years.

She just plainly didn't believe that 10 year old child could solve all exercises in head. and forced me to write down each single step - while the exercises themselves were already too easy.

I never got into a habit of challenging myself, thanks to her it is quite the opposite, and i now am really bad at doing math in my head.

I would say that lack of challenge was the biggest flaw in my education, i went throughout whole education(including university) without studying at home - not because i was so damn good, just because in my formative years the habit of working hard was stripped from me, and C-equlivalent to B-Equivalent was good enough for most subjects.

I expected for that to change as i managed to get into top 3 high school for my area.. yet it was mostly the same.

I am slowly regaining it thankfully, but it is way, way harder to do so as an adult. And i still wonder where else i could be in life if not for that single person, and what happened to other such children in this post communist country.
Me and Monastic Academy
Alternatively, you can parallelise parts of your build (eg the tests, static analysis etc) and speed it up. Then, if you have more changes coming in than you could parallelise is when you can start to do some advanced things like trying to predict which changes might break the build.

There was a longer discussion on one of these approaches done by Uber[1] on HN. Granted it’s a lot of investment, it’s interesting to explore ways of dealing with long builds that need to run frequently.

https://news.ycombinator.com/item?id=19692820
It's not just binary, it's a binary choice between "those jobs that are a bit like mine" and "all the other ones". Imagine what some hypothetical parents with other careers might say:

> ... between jobs that involve being outside (gardener, railroad worker) and those that don't (office worker, bus driver, ...)

> ... between jobs that involve creative expression of your emotions (artist, musician) and those that don't (office worker, bus driver, ...)

> ... between jobs that involve saving people's lives (firefighter, doctor) and those that don't (office worker, bus driver, ...)

In the above, "office worker" includes desk jobs like programmer, startup CEO, and secretary. To people in some careers, those all sound pretty much the same.

A less extreme version of that third example would be jobs that are more people-based (in a meaningful way e.g. perhaps including travel agent but not barista) and those that aren't, which would be a very significant split for some people.

----

As a separate point, and probably a bit more pendantic: I think that even "making new stuff" can mean two different things. If you look at manufacturing e.g. building cars, you typically have a split between interesting design jobs and the factory floor where stuff actually gets built but the job is pretty boring and maybe sometimes even low skilled. Computer programming, even low-level implementation, is more analagous to design in manufacturing (then the "creating" is the trivial file copy of the executable).

But again, to some people that distinction is important and they would rather be building something physical with their hands (plasterer, carpenter, etc.), even if it's to someone else's design, rather than doing something that doesn't involve fine motor skill even if it's "creating" software or car designs.

Using a (widely trusted) blockchain you could provide a mechanism for people to make sure you have not tampered with the historical records.
>Ubër has also built a service that I, for one, strongly prefer to traditional transportation services.

This is a big reason why things are the way they are: despite all the obvious externalities Uber (and AirBnb) foists on the public, the rich support if because it benefits them.
GPUs can jump to function pointers and some GPU languages support them.

Have a look at "4.2 Branching" in http://developer.amd.com/wordpress/media/2013/12/AMD_GCN3_In...

Also, it's possible to compile code using function pointers down to more limited forms of flow control instructions.
To believe in a one-world government, I think it’s almost a prerequisite that you don’t care about what people actually want. The only line of reasoning I’ve seen sincerely put forward for creating a central world authority to rule over all people is that some people think they know what’s best for everybody else. Not only does what actual people want not matter, but in order to achieve their utopic vision, they must protect people from themselves when they want the wrong thing.
Doesn't paying encourage useless sites highly optimized to grab user attention, low quality content, shock sites, cloned sites, site bloat (if payment is per KB), and so on?

That said, I think there's definitely a space for paid internet. I was just surprised because siasky homepage says "Build a Free Internet" - perhaps it should say "Build a pay per view internet" instead?
Shepard's Prayer
The OP specifically asked to leave cryptocurrencies out of it and judging by the post does not consider finance to be a 'substantial' example. Are there any concrete examples where blockchains are both useful and necessary?
We don't know how many people covid19 would kill if everyone were infected. Given the data we have now about covid19, cars probably killed more people in the last 15 years than covid19 will kill people in the next 15 years.
True, but that type of optimization is quite moot if you're only running the build at night (i.e, that's not the first constraint to solve). In the article I mention that first get the builds to be tight one after another, then work on build times because that becomes the constraint.
And the primary reason for climate change is having so many people on this planet in the first place
Thanks for sharing this guide. For those (like me) who are lazy and want to delegate the hard work and maintenance to folks smarter than me, starship is a cross-shell prompt that will print duration of commands. https://starship.rs/
That's a good way of putting it. In TOC terms, the build time becomes the new constraint to solve, but only after you solve the build frequency constraint.

Those 6T haven't been spent, right? Those are funds committed towards "stimulus programs" (whatever that means in the end) that will run over months or years. It's still a staggering number, staggering also in comparison to other world economies. That is probably the intended effect.
My advice is for you doing exercise first thing in the morning as a routine.

It will give you energy(unlock your lymphatic system, improving your circulation, clean your waste) , activate your brain and body(generate activation hormones and oxytocins).

I recommend using the TV so you don't have to think(plan) what you do, just do it.

You can do yoga, you can do zumba, you can do samba or dancing, you can do strength, martial arts, bike, table tennis.

Right now everything is downloadable in torrents, and you can test any good program about any discipline before you decide you want to buy it(once you know you will use it).

I suggest you try for 30 days something different each day and you will find what you like to do and what not.

Once you know what you like, it is a good idea to buy the program so you make a(small) financial commitment that will help you to get used to the routine each day.

Once the routine is set in place, the difficult part will be not following it.

This working-style reminds me more of the weavers in Europe at the end of the 19th century. Home-workers will easily just be rated (and paid) on the amount of work done per day. As there are always others who will be more productive, wages decline. At the end, whole families have to produce digital content to make a small fortune...

On this topic, I have recently been quite enjoying and impressed by the game Rec Room (https://youtu.be/6kl9gqv9t_I). It's already well on its way to being an actual metaverse (it can be played both in VR and on a computer, for free, and has a far more flexible system for player creation). I kind of hope it ultimately prevails over the likes of Facebook or Tencent.
> Some types of speech are harmful with little benefit, from my perspective.

But for the people saying the things you don't want to hear, that same speech is beneficial, with little harm.

It's easy to want to ban things you don't want to do. That's the entire point of it being protected in the first place.
Ask HN: As a Facebook or Google engineer, do you consider your company evil?
Amid the severe backlash that tech companies currently face (Google and FB amongst others), how do you consider your own company from a moral POV?
Do you think the current backlash is justified?

No judgement, just curious.
Efficient products,saving easily on this platform
Assuming the only real use case is when all parties don't want to trust a central authority, the use cases do seem limited. Because once you have to trust anyone, you might as well use a simple ledger/database.

In the airline space, for example, all the airlines pay OAG to file schedules. OAG is a central authority they trust, and pay. Blockchain could replace that, and save them all some money. Hasn't happened though.
Bitcoin solves a real problem: It creates a permanent fix for monetary inflation, which allows people to save money without being taxed on their savings.

The rest of "cryptocurrency" is snake oil. Most of it attempts to reintroduce inflation and undermine the fix which Bitcoin introduced. While they may come up with a bunch of reasons for their decision to mint new tokens - the sole purpose of the new inflation is to enrich the creators, who intend to exchange their zero production cost tokens for some other tangible wealth before the naive buyers of the tokens realize they've been scammed.

Building on top of Bitcoin is the way to solve real problems because each development strengthens the permanent fix on inflation and enables Bitcoin to be more accessible.

A "blockchain" is just a linked list where each tail item is content addressed.

> Nobody is going to start a war with China.

Hopefully you are right, and I share your opinion (if that is what it is) that there will be no war in the immediate aftermath of covid-19. But I need to point out that the cited remark represents a kind of absolutist statements about the future that have had a chronic tendency to be wrong up through history.

There is definitely a risk for war with China as long as the US have a considerable number of weapons pointed against China, a war triggered either by intent or by mistake. The best way IMO to avoid the risk of war is to work towards total disarmament under the oversight of transparent and neutral international agencies. And discredit the warmongering on all sides.

Somehow and unfortunately I don't anticipate that such initiatives will be accepted by the world main powers, or by a frightened and easily manipulated public, any time soon.
Spies should carry crossbows more. They're pretty quiet.
problem #1 - protect freedom, liberties

problem #2 - adaptation to the needs of the complex system like modern society

those are kind of ‘significant’ problems, technologies like Internet, blockchain etc, provide sequential approximations to the solution of those problems.
This is only true for their first 5 years. The prices you pay now in US are absurdly profitable for Uber
A lot of people in this thread keep wondering about the choice of Basic and end up suggesting other programming languages.

This always comes up as one of the theoretical use cases or when a big company says they are doing blockchain now (which in reality is a small team evaluating if this new technology is worth it for them).

Do you have a source for where this is actually use in production and not as POC in a lab?
Hysterical.
I'm probably a standard deviation or so below you — I've met 2-3 people like you; it's really incredible and refreshing to converse with those people. I'll be making an argument, "Premise A, Premise B, Premise C..." and they'll often just just derive that I'm going to say D, E, F therefore G. On, like, quite novel arguments. When it's happened, I've always been like - wow. It's really incredible.

Two thoughts.

(1) I wonder if you could frame learning to communicate and get satisfaction from interactions with merely "quite smart" people as a challenge worth pursuing. You could brush up on negotiation, sales, rhetoric, poetics, etc. Perhaps slowly start converting those domains' messy forest of heuristics into some principles and equations, if your mind works that way. If you were able to, for instance, detect someone lying to preserve their own self-image around something they felt ashamed of, and then were able to navigate that to help them both renounce the lying without feeling bad about it and help them reintegrate their self-image around the concept — that sort of that is immensely cognitively demanding to be able to do, and it's pro-social (you might not care, some people do, but at least it's not pathological in any way)... in any event, that'd increase the amount of cognitive processing you'd be forced to do in any given interaction by an order of magnitude or two, which might make those interactions become enjoyable. You'd also rapidly become massively liked and trusted.

(2) With your intellectual horsepower, if you were willing to, you could absolutely seek out and cultivate a dozen or so people on your level cognitively. It'd take a while — you'd need to think through exactly what environments you navigate at what times and in what ways, how introductions get made to you, etc — but if you were to meet ~1000 people in a thoughtful thought-through way, then I'm sure you'd find at least a dozen or so close friends and peers to associate with. It'd be a multi-year project, but not incredibly time-demanding on any given day or week. I imagine it'd be worth it.

My two cents. Seems like it'd be terribly unfortunate and much less satisfying to not be able to fully actualize and explore all that raw capacity with other good people.
I’m not really impressed. This only applies to shots directly taken from the free throw line . Make a basketball hoop that moves based on ball flight Now that would be impressive. I have seen someone on YouTube do that with a dart board.
The distributed operation I consider necessary for something to be called blockchain technology. Git is an example of a Merkle tree [1], which definitely is a key component of a blockchain but not enough on its own. One also need a distributed consensus mechanism.

The distributed operation is both necessary, and the key challenge for blockchains. There is a heavy cost to secure distributed operations. My personal opinion is that most people don't care so much about distribution, they're fine with a few trusted/regulated actors using more efficient centralized schemes. And this is, in a nutshell, the big challenge of blockchains IMHO. And why some people are tempted to drop the challenging part, put a centralize scheme on top of a Merkle tree and call it a blockchain to ride the hype. I don't think this is correct, both technically and ethically. It's "merklewashing" ;)

You describe my double feeling quite adequately. I'm so happy my children have enough space to play and partially live on without lacking much except school and friends. On the other hand I miss office life and the way it quitely demands social contacts and intellectual novelty in a way my home work doesn't. We get all work done, perhaps even more efficient than in the office setting, but the novelty sure is gone. My work has shifted from change to production.
Silent pocket sales will definitely see an increase from this.

The problem is incentives. I absolutely agree that we should build more. Building brings us closer to the world outlined in the essay.
But building more doesn't solve the kind of problem like how we were unprepared for the Corona virus.
Neither in the health care system nor on the political level are there any incentives to act in the long term, taking rare events into account.
Preparing for rare events does neither help the current quarterly figures nor a re-election. On the contrary, such preparations require money and attention. When the disaster is there, a government can act in crisis mode. Sums that seemed unimaginable before can be waved through quickly. Even governments that have been in power long enough to take precautions are now getting approval for at least not failing completely in the crisis. And with the approval won, the government still has no incentive to change anything in the long run.
We need to adapt our systems to reward long-term incentives and preparation for rare events. I doubt, however, that the actors will be able to make these adjustments on their own.
There are some correlations between BCG vaccines (especially the Japanese strain) and covid-19 doubling times[1][2][3]. But these are just correlations so far.

There is also an ongoing study in Australia to try to find if there's really a relationship[4] and some talk about trying a similar trial in Boston[5].

It will probably be while before we see any specific results.

Yes, perhaps. That's what California is attempting. Unfortunately social security in US is national, so you can't operate a closed system.

E.g. only Danish people can get Danish social security
I also do not use an alarm clock for waking up. My body is my alarm clock because of routine and discipline.

If I need more sleep, I let my body sleeping more. Most of the time I don't need it.

In fact I use an alarm clock for working in chunks of 50 minutes, resting 10 minutes. Over time I have a very good idea how the timer is doing without looking at it.

To emphasize the original point more strongly: in the UK a road surfaced with cobbles would be described as "cobbled" not as a "cobblestone street".
