Ask HN: Best practices to launch a new physical product?
We are in the process of launching a new physical product (clothing items). We have been working with ~100 target users for feedback and research and they are looking forward to the launch.

Beyond this do you have any recommendation on how to acquire our true 1000 fans.

Thank you in advance!
When we designed DCCP, I did a formal model using LTSA to prove liveness and safety properties. Mostly I did it for fun (I got landed with teaching concurrency, and the previous professor had used this tool). As formal models go, LTSA is rather simple. I was pretty surprised when it found a previously unknown deadlock state. To my chagrin, a decade or so earlier, I'd observed a very similar deadlock in the Solaris TCP stack when running SMTP, which is unusual in that it requires the server to send first.

I shared the LTSA model with a few others at the time, but no-one else seemed very interested in doing anything with it.

Edit: I dug through my old backups, and I think this is probably the model I used:

It's nothing fancy, but my point is that even simple modelling can spot errors that a whole standards group of smart people miss.

> There are two different kinds of freedom here: The freedom for society to govern itself and the freedom of the individual.

...

> My belief is that a society can exist where society is unfree (due to say a dictator) but individuals are free (a fair set of laws is in place that causes minimal harm/maximal good). This society is just as free if not more free than a democracy.
Therefore, democracy is not freedom.

Well, I'd be okay with your distinction if you didn't contradict yourself here. Is the society free or not?

It appears to me like you're suggesting that a dictator who valued individual rights could create a society where the people in it have no recourse short of a forceful overrule to change they're rights, but who'se forced upon rights are vast and very generous. So you'd classify this as an unfree society, but one where freedoms are given to individuals.

But that would mean that dictatorship is not free, and thus not equal to freedom or a free society. While democracy is free, and thus equal to a free society. And that ones individual rights is almost a fully orthogonal concept. Which is what I personally believe. And why I think both are important to maintain. Individual and human rights must be fought for, and made law, protected against strongly. Yet society need also be free, and democracy is the best implementation of a free society we have.

Now sure, in a unrealistic scenario, where a dictator would give me almost idealistic individual rights, yet the neighboring democracy would give me subpar individual rights, I might prefer individual rights over it. But that example is just ridiculous. In practice, this has never happened, and that choice doesn't exist. But I take your point was that individual rights might trump a fare election system, and I think I'd agree with that. But again, I see that in practice, one is rarely there without the other, probably because most people who value individual rights, also value the freedom to choose who govern them.

From my experience both wget and curl deserve respect. Both are fantastic tools, similar in some ways but covering much ground in other directions. I find wget ideal as a spider (checking broken linnks, making local backups of webpages and similar) while curl is much easier to use for quick inspection of web pages (including headers and https certificates).

This isn't true. Given a manifold that satisfies the vacuum Einstein equations and given a world line in that manifold, it can be shown that the world line is undergoing acceleration using only local calculations/measurements. The worldline of a particle on the edge of a gyroscope will have a non-vanishing acceleration and this can be computed using local calculations/measurements.

You can describe the manifold using a coordinate system corotating with the gyroscope, the worldlines will still have a non-zero acceleration. There is absolutely no need for any matter field satisfying hyperbolic PDE's with faster than light characteristics.

>So you are basically saying that someone who earns a shit-ton of money should live in a 1 bedroom apartment

No, I am not telling anybody to do anything. I am pointing to the existing legal possibilities because Zurich's landlords are arrogant and sometimes write clauses in their rent-contracts that "break" Swiss law ("only 1 person can live here"). I am trying to highlight that Zurich's jurisdiction is renter-friendly and laws are applied rigorously.

You can calmly rent-sign a contract with weird clauses, because they are invalid, so you can break them and the landlord can't kick you out for it. Worst case is you get infront of the "Schlichtungsbehörde" which is a pre-step before the court, where a volunteer-landlord, volunteer-renter-representative and a neutral party will decide over a dispute quickly (and cheaply). So please make sure you are member of mieterverband.ch, if you live in Zurich.

When I learned about high-frequency trading, I toyed with the idea of opening up a stock-exchange with different rules:

- one quote per day
- transactions of the day are processed in a random order (using a provable random deterministic algorithm)
- shares have to be kept for at least 3 months (Warren Buffet recommends 6 months) before being sold.

When Steve Jobs died, which was obviously an event that would have an impact on Apple's shares, the quotation was suspended for a day, so that people could take their time to evaluate the significance of the event. This was a confession that they knew that the high frequency changes is just noise and that the signal has a lower time resolution of about a day.

Further, the US government can literally inject money at will into the market. That is what is happening when you have interest rates less than or equal to 0.

Wget is first and foremost aimed at being a file downloader/spider. If used with no switches it will grab the first file behind the url and save it locally.

Curl on the other hand it more of a HTTP client lib with a cli interface. Unless fed a specific switch, it will send the file behind the url to stdout. Meaning that it is more at home at one end of a pipe.

Just read through some of your blog posts. Sadly I'm not in a position to be a patron. I really, really like your writing. I want to write too, but most of my writings are stuck in a journal half-finished. Do you have any tips to fleshing out pieces of writing like blog posts?
Is that so of civil law? It was my understanding civil law is specifically designed for this, that is, promoting civility amongst people. Courteous debate and disagreement is possible, even if one argues the other is a monkey. Such speech promotes arguments and content over appeals to hateful emotions, ridicule, and fear. The latter type of speech, to me, are actually psychological weapon of anti-free speech. They target someones else thoughts and speech, by inciting fear and blocking out reason.

Insulting someone, calling them names, threatening their well being, shouting at them, and inciting others to do the same, those are all tactics to shut out the targeted individuals. Make their voices irrelevant, ignored, and their will to speak smaller in fear of retribution.

Now I think we're smart enough to find regulation that are smart enough to restrict only that kind of speech, and if it's non obvious, I'm okay sitting on the side of allowing it. But some of today's speech is just blatantly the latter, and thats true in all political spheres, and even in most apolitical spheres.
My two cents: if you treat it as a proper responsibility and as essentially a furry child, you have no moral or ethical qualms. If you can satisfy its needs and help it lead a pleasant life free, that's enough.

On a related note, I had a professor in college who was a Buddhist and considered his living situation as involving a "cat who lived with me" and not "his cat" per se. I think that's a much healthier way to look at it. It preserves the cat's agency and rejects possession of another living being.

I'm afraid the material is some handwritten notes in Spanish, interleaved with some code examples in PROLOG. They were quite systematic IIRC, covering basic logic, data structures, proper use of the !bang for performance, etc.

I no longer have the exercises in code, just paper. I've yet to scan my handwritten notes and bring them to the digital era :-) This may prompt me to finally do it.

If you still want them, I can send you the scanned pdf to your mail. However, I think you'd better off with some free online course. On a cursory examination, this one seems similar to the content in my notes:

Me neither. Especially considering that this story was already alive before the latest deep learning advances. It is totally believable.

And even with a modern CNN approach, you would expect a model to be able to learn a sunny/cloudy categorization much easier than the nationality of a tank.

This story was repeated by professionals for ages because it is totally believable.
The good torrent sites do have token systems, though, and manage their economies in pretty interesting ways, e.g. periods of "freeleech" to stimulate engagement; stipends for new users; bounties for desirable rare content; etc. And this goes back to warez FTP sites.

Maybe private trackers would be a good use case for blockchain storage tokens. Certainly the hypothetical seeding ratio I could have on a certain private tracker for art film would be actually valuable to me.

I'm not sure where you're looking but around my parts, 1024, 2048, 4096 bit RSA is most common. Most of those are 2048 bit. I can't think of a 3072 bit RSA key I've run into in the wild. That's usually TLS, GPG, SSH keys.

I think the only real problem these storage tokens try to solve is incentivizing people to seed random stuff without active selection made by the seeders.

Whether or not we need a cryptotoken for that is debatable, but I don't know of any other alternative that would keep the system entirely decentralized.
The thing is..owning capital isnt what it used to be with jewels piling up. Credit allows debt backed by that physical collateral to be used for someones tractor to be built. These people may be 'worth' a lot of money but their wealth is actually more diversified and illiquid than the average person's capital. I think its an important distinction because we can easily lose sight when we don't realize that one person's wealth isn't a zero sum loss for the rest of us. In a credit debt economy, we still lose but not binary..more like a percentage. Their money is out there doing work, helping other people. They can call it back eventually..but if someone is so rich they never actually recall their 'floating' assets, is it economically scientific to consider those assets equal to cash under a mattress? I feel like we need a new measure for almost perpetually floating assets so we dont consider ownership as relevant.
All those companies argued that for the last 9 months they sat on the Yubikey vuln key issue.

I always thought it was a pretty silly system too. You end up in a situation where you want do download something, other people want to upload that thing but you don't do it because you don't want to ruin your ratio.

This in turns means that these other people don't increase their ratios and end up in the same situation. You have an artificial 0-sum game for absolutely no good reason. Then you need freeleech periods or bonuses to make up for the ratio credit "deflation".

I think it would make more sense to punish people who never seed (seeding if nobody is downloading is fine, you can't do anything about it) and incite people to seed torrents with a low seed count.

It actually does seem a little faster, which is sad. I would like to see how much normal userspace can be optimised, and where the delay occurs:

2. in the input subsystem
3. in the app / system libraries
4. in the display subsystem
5. between the CPU and the screen
If you spoke to a supporter of what you describe they would no doubt point to the extra economic activity created by the new money that would otherwise not be there - if we strictly only lend against deposits this would mean we would all be far poorer than we are now. As long as we all believe in the new money and expect our creditors to pay us back as promised, the sleight of hand works.

That's what a supporter of the current system would say. Personally I think the whole setup stinks and any benefit the average person gets is merely a side effect of a system designed for the benefit of the rich.
There is also a reason I can do 99% of the things I do on a laptop on my (totally sandboxed, not rooted) iPad Pro.
