> Find counterexamples to each of the following algorithms for the knapsack problem.

Anyway, yes, in the strictest sense of the term, it is unsolved because it's NP-complete, however it's been thoroughly analyzed in many different ways (it's pseudo-P, we have a MITM algo, different flavors of approximations, etc.)
Not even back then was this tied to being in an union in Poland, but to having right certification which anyone can get provided they document having passed training and exam.

And indeed, the force people to join bit was outlawed in EU in 2006, but it was never particularly popular outside UK anyway.
You can certainly buy shoes that will last for decades, if you're diligent with maintenance.

BUT, you're still going to need (probably) multiple resoles, patching, and what not.

Take a look at the shoes Prince Charles is wearing - they're bespoke shoes from the 50s.

But you need to ask yourself - at what point do you just scrap them, and buy a new pair?

Some people love the vintage "relic" look - but every resole and patching is going to cost you money. Purchasing a pair of $1000 shoes, and then spending $1000-$2000 on maintenance the next 50 years will make sense for some, but not for others.

I personally, would much rather just buy a new pair of $500-$1000 shoes every 10-15 years, and discard the old ones when they start to look too shabby.

I live my guitars old and reliced, but shoes ? No thanks. When / if my shoes need patching, I'm throwing them.
As heavy critic, but also fan, I have been following up on it, and the last update on the document is from September, so I am positive they might make it, it just appears the proper implementation still has some engineering challenges.

There's little point owning an EV if you can't charge it every night in a garage/driveway/street.
> Technological advancement is good in its own right.

I don't think it's as clear cut as you want to believe. Technological progress is almost exclusively fueled by economical gain, economical gain rarely aligns with long term progress.

Was leaded gas a progress ? Freon ? Asbestos ? Privacy invading social networks ? I guess it depends on the scale you look at it but it's more "is technological progress always desirable ?" rather than "tech is always good, always trust the tech, always praise the tech"

I believe that modern landfills are not permitted to have run-offs (i think the term is 'leachate') into the environment. There is a water-tight lining between the ground and the actual landfill.

So I suspect that in practice plastics sent to landfills are effectively sealed from the environment, at least in most Western countries.
July 6 - August 6 - September 6 -- that's 2 months elapsed, not three.

Five people working for 2 months is 10 person-months. Apple paid them just under $52,000, none of which was guaranteed. They had to pay whatever taxes are appropriate for their jurisdictions.

I'd say Apple got an amazing bargain.
Even just comparing total number of deaths this year to last year is pretty gruesome. From the same website as the original article - https://www.ons.gov.uk/peoplepopulationandcommunity/birthsde... - the second last paragraph of section 2 reads:

"Looking at the year-to-date (using the most up-to-date data we have available), the number of deaths up to 25 September 2020 was 453,771, which is 53,888 more than the five-year average."

That’s just in England and Wales.
This is the real question :) Of course it will be by some far left leaning person. Zuckerberg said they have content moderation and consult with many many groups and the interviewer asked for ONE example of a conservative group they consult with, he had no answer.
> The "ore" (called Tamahagane) is sandy/rocky stone material which needs to be forged repeatedly to remove impurities and get a higher carbon content in the steel.

FWIW tamagahane is already a steel, made from processing ironsand. Tamahagane is not the raw material.

Ironsand is found throughout the world, but outside of the japanese few made actual iron (or steel) out of it historically, because there are usually better sources of iron available.

NZ is an other country which is very poor in iron ore but it has a lot of ironsand, some of its beaches are ironsand (which is genuinely dangerous: it heats up quickly and very high in the sun). While the japanese were largely the only historical users of ironsand, I think NZ is the only one which industrially smelts ironsand.
The only democratic way to have a vetting system for political messages would be to have an transparent government institute that are responsible to the public, and it seems to me then that we have just reinvented the censor bureau of the past.
Of course, you can use deep learning algorithms without even knowing that you are using them. I do not want to disuade anybody from doing that!

Maybe I misunderstood the question, but the GP said they wanted to "study deep learning". I do not think that is feasible at all without some math knowledge.
Perfect example of regulation having the opposite impact of its stated intent.

Its 100% better to dispose of something that “maybe” recyclable, rather than “wish-recycle” it and contaminate an entire load of material.
In the argument you made, private versus public is entirely irrelevant.

There are two free speech arguments. Keep in mind that "free speech" is not relegated to the 1st Amendment and defenses of that generally lean on supplementary law.

1) The free speech of the user. Again, while it's true that it's not protected within a private entity, it's irrelevant because your protections are limited; in this case when your speech breaks another law.

2) The free speech of the platform. Being compelled to reveal this information really doesn't even touch any free speech argument except a vague interpretation of shield laws. DMCA as it exists provides legal protection against the crime, of course.
I sorted exploits by date, it made a fun short headline summary of how productive they were. Short answer: very.

I know it’s hard for senior management to want to really commit to bug bounty programs like this because it feels embarrassing and vulnerable, but posts like this should be sent around the boardroom when discussing — apple rented an AMAZING security team here.

C != C++. Really wish people would stop lumping them together. Compilers support both, but many compilers also support D, Obj-C, Obj-C++, assembly, etc.

This article focuses almost entirely on C++, but the title would have you think otherwise.
I find HN to be a very specific political demographic of great interest, so when I read it, it's with the specific intent of exposing myself to the point of view of this very specific political demographic.

That's not the same thing as a specific POV or catechism: the demographic actively seeks novel answers and ideas in certain ways so long as larger assumptions remain unchallenged, and even then the right framing can work wonders. It's the demographic that remains consistent, even predictable. The position of this demographic isn't always a given.
"To be brief: Apple's infrastructure is massive. They own the entire 17.0.0.0/8 IP range, which includes 25,000 web servers with 10,000 of them under apple.com, another 7,000 unique domains, and to top it all off, their own TLD (dot apple)."

Wow. I would think it's just impossible to secure all that, and that's not even everything.
NP-complete doesn't mean unsolvable! It means that we don't know any algorithms that run in subexponential time for every input. But of course we can use the algorithms with exponential worst case running time. We can also use algorithms that solve most instances fairly quickly but may take a very long time to solve some particularly hard instances.

There is a lot of mythology in this area about steel folding, which acts to even out the amount of carbon in the steel and remove impurities as slag. The corresponding Western process is "Damascus steel" and you can still get decorative "damascening" (which is often just faked on the surface).

The blog I would refer people to is https://acoup.blog/2020/10/02/collections-iron-how-did-they-... (in general as well as that post); I don't think they've covered katanas specifically but they are great on detail.
Nice read, like Forensic Files for hackers.

However I am stunned that they did not earn past 6 figures. I was a bit primed with the $100.000 bug earnings.

Fortunately those of us on HN relearn software ecosystems every few years, to teach us humility.

I often wonder if there had been a class distinction in the "it's all greek to me" saying in english? For some englishmen, the simile would be saying that it was incomprehensible foreign squiggles, and they'd never understand, but for others it would be saying that it was incomprehensible foreign squiggles, yet with a bit of swotting and practice they'd eventually understand.

CASSIUS: Did Cicero say any thing?
CASCA: Ay, he spoke Greek.

I saw the free speech angle as related to the government’s ability to go after Twitter, and this user. (But I agree with GP that the point is moot if they impersonated the FBI.)
> Makes me wonder, if these guys could do it, how many Chinese industrial espionage units have?

And Russia, and Iran, and so on... It seems safe to assume someone else out there found at least one of these and got in to the Apple internal network and has been quietly doing their job, whatever it may be.
I would expect somebody who has "nothing to do with neo-nazis" to say "wow, I've made a huge mistake" and leave the first time they hear somebody they are marching next to shout "gas the k--es, race war now". Who specifically are these hypothetical good people?

Unlike you, I do believe that every counterprotestor was associated with antifa. It was an antifascist counterprotest. That is antifa.

Support for the Lee statue has never been seriously about history because the supporters of keeping it up never asked historians. I'm serious. UVA is an excellent history program. They could have asked the history faculty to decide. It wouldn't have gone in their favor.

So now you want to blame Vulkan for mobile hardware variety and lack of Android updates? You can still use the lowest common denominator that is supported for all your targets. If you want to have code paths to enable more features on some devices then do that. Complaining that Vulkan gives you the freedom to choose where to make the cutoff for feature levels is pointless.
Yeah, it IMHO only makes sense to treat it as genericized term for "big tech company", not as the actual firms in the acronym.

End of the post it says 51k so far. I'd expect the price to go up a LOT more, because otherwise the sane (monetary) advice becomes "report some vulnerabilities to apple, and then keep finding them and sell them to third parties".

I thought metamoderation was a brilliant idea, but I'm not sure if it had practical benefits.

It's certainly very interesting to talk about, at least for me!

Starting with the results and working backwards, I didn't find the results of moderation+metamoderation on Slashdot to be superior to subsequent sites like Reddit and HN that skipped the metamoderation portion.

Why? I think metamoderation on Slashdot was ultimately redundant. The metamoderators were also the moderators. So your moderation was being moderated by the moderators that moderated the posts. The metamoderation was not really of a higher quality than the moderation, so it didn't really add much.

Metamoderation was good at flagging grossly incompetent moderation, such as somebody seeing an ASCII swastika and upvoting it. However, as long as the community as whole is relatively healthy, that sort of poor moderation would be rendered moot anyway; such a post on Reddit would receive perhaps 98% downvotes and 2% upvotes, it's not clear to me that preventing that tiny 2% minority from voting in the future would be demonstrably better than simply drowning them out which is what happens by default anyway.

Metamoderation could perhaps be useful if the metamoderators were guaranteed to be trusted, high-quality users.

Slashdot tried to do something like that; IIRC you got the opportunity to meta-mod after you were up-modded yourself, so theoretically "better" posters were doing the meta-modding, but in practice I think this just added an extra layer of echoes to the echo chamber.
> they would prevent posts from spreading to tens of thousands/ millions of people without being vetted.

But _the precious engagement_!

Viral nonsense is, unfortunately, effectively Facebook's business model, so they're unlikely to do much about it.
I saw somewhere there was some confusion in translation what decriminalization means, as Portugal has Roman Law as opposed to Common Law found in English speaking countries. Portugal "decriminalization" of drugs left it in a similar state to British law anyway. I can't find a reference now though - does anyone know more?
Late to this but I've owned 2 Leatherman Waves and will continue to own them as long as they are produced.
I've lost one, and the second purchase included having the tool replaced for free after 5 years when I'd ruined most of the features due to hard use. This was a mix of 'professional' and hobby use.

This brings to mind some considerations for you:

1. Professional tier tools are often much hardier than consumer, and often a pro tool would last a lifetime for a consumer user, but only a few cycles professionally

2. Warranty and replacement is very important here. Example is Osprey who _had_ an incredible no questions replacement, but they've changed it while keeping the "all-mighty-guarantee" name.

Elements to consider. I'll try add a Leatherman review.
Cute!

Yes, I don't disagree with any of this. Let me rephrase that. The problem of determining what is the minimum asymptotic time complexity for an algorithm that correctly solves any knapsack instance is unsolved.
A better reading of his comment is this. You can analyze side effects easily in a small function or system. Not so easily in a large system. That's why it's better to avoid side effects.
You seem to completely misunderstand what the union formed at Kickstarter is about. Nothing like what you describe, but rather giving employees more control over the company's decisions.
I’m a hiring manager with a global team. Yes salaries for Europeans are generally much lower than USA employees. Except Switzerland. They’re getting paid similarly to people in the more expensive parts of the USA.

There’s a few reasons why EU compensation is so low. One is it’s expensive to hire a person in the EU. We have to pay a lot in taxes on the employees behalf. They never see this on their check stub - it’s paid as part of a payroll tax. We have these in the USA as well but much lower and parts of it phase out as the employee earns more. Keep in mind that the USA employee may have to cover certain things like part of their health care though.

Secondly it’s far more difficult to get rid of an EU employee. We can of course, but it can be more expensive.

People make more in the USA and it’s a reason a lot of people from EU/UK come here to work in professional roles. Lower taxes and lower costs of employing someone send the money to the employee. But also a lot of the covered benefits (health, pension, etc) the USA employee has to cover themselves out of their pay (pre-tax though). So in part it’s a visibility thing too.

I'm in the same boat. I started living a more minimal lifestyle about 2 years ago. All my stuff fits into a 35L bag.

So I prefer to pay a premium for high quality durable products. If they can solve the trust problem, I'd be a customer.

I hope for a larger counter movement to the consumerism today. Reward companies for making durable products and punish those who don't.

Great idea!

If this former Citi employee can successfully argue before a court that his views are the result of a sincere religious belief then I believe he should get his job back.

To be clear on my position, I am not advocating for the government to step in here or even that he should be able to seek legal recourse. I am merely lamenting the fact that we as a society yield more to emotion and reaction rather than trying to instill principals in ourselves that are applied evenhandedly. I am not advocation that we regulate companies abilities to dissociate with employees, just noting that it's a shitty thing to be fired for your personal life and it was shitty when it was done to people of a different cloth in the past.

Too many people have grown too comfortable venting on the internet expecting there will never be consequences for their posts. So comfortable in fact that if anyone dare say they don't want to work with you or interact with you there are accusations of persecution and analogies of persecutions past (or at least a slippery slope fallacy argument that it is coming).

I don't disagree with you here, I think with the exception of a few pockets of the internet online discourse is leading a net loss of humanity. I think the general population feels free to just hang it all out there when they are not face to face and that is an issue. Before all of this people did tend to self censure a bit in front of polite company, if you will.

I differ a little on the not want to work with you part, and I think that is the sticking point. If they are not bringing it to work and the work discourse never leads to those subjects. I don't think it is the purview of another person to decide that they should not be employed because they don't feel like working with them.

Now I will give you that this is a nuanced conversation and there are a lot of issues such as if a person is actively advocation for violence, but in my view that is the point where a idea or belief that someone hold starts to move towards being the planning of crime. I hold this stance across the board, if ISIS calls for Jihad is no different to me that if a QAnon member calls for a race war or if Antifa/Proud Boys calls for rioting.
Not even just the time, there is a clear energy cost that every household has been paying electricity and gas costs for heating of water. Extra cleaning materials in brushes and washing up liquid and additional dishwasher tablets etc etc. I doubt most households have good enough accounting to attribute the cost of recycling directly other than perhaps the cost of recycling bags (ours requires all recycling in clear bags) but it goes well beyond just time, we have literally burnt CO2 to recycle something that actually can't be recycled.

What I don't understand is why governments and councils continued to go along with this, to collect it all separately and then just send most of it to be burnt or landfill, the cost surely wasn't worth it. My Freedom of information act request to my council about plastic recycling was eye opening, just 3.2% of the plastic put into recycling correctly was actually recycled. They know full well this is pointless and yet it continues.
Go will eventually grew up to be like Java and Cä# in 2020.

Java was released in 1996, and only got enterprise-style C++ adoption around 2000.

Until then, the inheritance and enterprise-style programming was done in a mix of Smalltalk, Eiffel, C++ and C based OOP.

Julia is basically Dylan/Common Lisp at its kernel, Java and C# are getting all the ML like goodies to stay relevant, see C# vs F#.

Cosmetics are potentially harmful to humans, and that harm can be prevented by testing on animals first.

Maybe there is some risk of this tinnitus treatment causing harm (could be something like https://en.wikipedia.org/wiki/Havana_syndrome), and animal testing would avoid that. But it's not necessary to inflict extra suffering to show that. Maybe they had to show the combination of the treatment with tinnitus doesn't cause harm but I doubt that.

There's also an argument where a disease is rare and inflicting animals with it to allows for efficacy testing, but tinnitus isn't rare, plenty of human volunteers are available. (I mean, half the people in this thread have already "volunteered" to perform testing of possible treatments on themselves, myself included).

Lastly as others have pointed out there are many causes of tinnitus. The researchers only inflicted one kind of it (I'd assume it's the same kind that everyone hears after hearing loud noises, since these guinea pigs were presumably otherwise healthy), it's possible this treatment only works on that kind and is a waste of time for everyone else.
Point b, "if you don't like it go back to your country"... they might be earning more, but the cost of living is WAY more than in their home country, I agree that they might be able to save some to no go back empty handed or to send back to their family, but why should they suffer in the meantime?
You tell the taxpayer that you will just stipulate a very large sum until they instruct their bank to hand over the details. If they are willing to pay the stipulated amount instead of handing over the data you raise it because it was obviously too low.

We already have other methods of desalinating water, so not sure why this would be a step forward toward that idea. Also, a Stillsuit was not supposed to desalinate saltwater, but to purify urine and sweat, which contain many more chemicals than just NaCl.

Because spring steel is even better. Before that, European swordsmiths did the same with Damast-steel. Spring steel made stuff like rapiers, short swords and so on possible. And long-swords, which only worked with spring steel against solid plate armor.

Katanas retain their sharpness better, so, as they are harder. And carried in wooden scabords and not metal ones as European sabres and such.
