To be fair, "quantum physics" is much too broad a brush here, your issue is with "quantum interpretations" or something -- I'm not sure this subfield has a really firm label. But it's fully of people tripping over paradoxes they invented and encouraging you to likewise stumble and admire how cleverly they tried to disguise their handiwork. In content it's unclear we've learned anything new here in the last 50 years.

But straight "quantum physics" covers lots of other, more solid, areas. Including understanding how lots of things you can actually manufacture work, like semiconductors and superconductors.
Plus the blog post is effectively a draft of said book.
An interesting thing about deterministic systems. If the deterministic system ever enters into a state exactly like a prior state, then from then on, that system will be in an inescapble loop destined to repeat forever.

If there ever was a repeatable state, I'd bet it would be at thr big bang, though i am no physicist.
But how long did they expose it to Roquefort?
Hello. I thought about what you wrote for a bit as I’m walking by some fields in the Netherlands.

Animal well being is of great importance to the Dutch middle class. Dairy consumption is high, and a high amount of the dairy sold, particularly milk, is advertised with animal well being. Just the milk cartons alone would tell you that cows do go to pasture a lot. That said it would be torture to have the cows stand outside the whole year. You can hardly get more domesticated than a Dutch cow. A golden retriever is more wild.

A lot of farm land, as a result, gets injected with fertiliser. In the summer the grass gets dried and stored to last through the winter.

I am assuming this is correct. I base this on what I see right in front of me.
Because I got down voted:

1) If he's arguing that SipHash (or any keyed) hash function is insufficient because one can presume that the key can be acquired, then that would render all encryption schemes insecure. The security of any keyed cipher or hash is always predicated on maintaining the secrecy of the key, period. If you throw that presumption out the door than they're all "broken".

2) If he's arguing that he can generate collisions by timing when an injected key collides, he never shows how that information can be used to reliably generate new collisions. At best he only _alludes_ to this. He says something about having code to do it, but then refuses to provide the code.

If a hash table only has two buckets, it's trivial to create collisions. For a uniformly random hashing function you have a 50% chance. But so what? Unless the hash table is a fixed size, when you try to inject more keys (usually 50%-80% of the hash table size) the table will be resized. This will happen regardless of the collision rate, and indeed you want to avoid predicating resize on actual collision rate because otherwise an attacker can force you to use up all memory. All you need for this is a simple counter for the table. (And of course your hash should evenly distribute keys, as SipHash does.)

If you use a fixed-sized table, then not only will a secure hash not help you, but neither will anything else. If an attacker can reliably generate biased collisions, then he can always cause worse-case performance, including triggering whatever fancy reshuffle logic the hash table uses after a collision, violating the presumption of amortized O(1) work.

Note that the paper cited in the Github thread (Wool 2009) presumes a small key space:

We have demonstrated that a remote algorithmic complexity
attack, against randomized hash tables, is possible if the
secret value is chosen from a small enough space. More
secret bits cause more effort, time and space to be consumed
in the information gathering stage. Thus, it seems that a
random value of 32 bits would render this attack impractical
with today's technology. Note though that in this paper the
attacker iterates over all possible random values in a
brute-force manner, searching for bucket collisions.
However, the search space may be limited to a smaller subset
of random numbers by taking advantage of the vulnerabilities
in the Linux Random Number Generator as suggested in
(Gutterman et al., 2006). This might lead to a feasible
attack against a server with a longer secret value.

SipHash takes a 128-bit key. The Wool attack isn't even remotely feasible. Even if the hash table is small and you're reducing the 64-bit SipHash-generated key to only, say, 10 bits, you still can't recover the key and you can't generate biased collisions. As for targeting Linux's PRNG, that same argument applies to all cryptographic software schemes.

EDIT: Previously said the Wool paper relied on fixed-sized hash tables. But it actually relies on a small key space permitting a brute force, oracle attack.
Did the locals also petition the police to arrest their own children?

I know what fascism is and in my opinion it is exactly what is happening in India in the current regime.

Today a BJP MP has openly declared that if the BJP wins the 2019 elections, there will not be a need for any more elections in 2024 or thereafter.
I’d say he is well aware of this. A lot of the things he makes are from reclamed materials with a mimimal amount of new stuff. He is awesome.

I would have loved this for baby formula. But I'm not sure if a family buys that for a long enough time for this to make sense for that. And most people try to avoid it nowadays. It also keeps for a pretty long time.

Our formula stock was a daily discussion. Will this last through the night? Running out was always a red alert though. Hungry babies don't care what time it is.
Far more dangerous than the idea it’s trying to silence.

I don't know about that. In the real world, there are homicidal maniacs, deranged ideologues trying to incite violence, paid propaganda outfits, state actors who masquerade as legitimate voices. If allowing them free rein is the price for "freedom", I'd rather have a little less freedom, because that sort of freedom is unsustainable and will, inevitably, destroy itself.

Ask HN: What do you think about internet echo chambers?

This makes me sound like a knee-jerk contrarian, but I think the majority opinion is wrong. Echo chambers are good! When you have too wide a chasm between points of view, you spend all your time bickering about surface issues. But if you speak to people who already agree with you on first principles, you can have a deeper discussion.

For example, a doctor and homeopath are less likely to have a productive discussion about health issues, than two doctors, or two homeopaths. A doctor and homeopath are just going to argue over whose profession is the worthless one.

is HN an internet echo chamber

Sure, moreso than most other sites, in that people on HN are better educated (and therefore more liberal) than the average social network. But I'd prefer it if the opinions were still less diverse.

and how do you tell?

Since I seldom see users threaten each other with physical violence here, I assume it's more of an echo chamber than most other websites.
I saw it is possible for netflix to direct user to a website to update his/her payment method. On the other hand spotify is not being allowed to develop such button in their app.

Netflix and spotify both delivering digital goods.

Why does such policy difference exist?

I asked apple officials and waiting for a reply.

We also have a digital goods transaction based app.(digital photo) We are also not allowed to use such button. Why does netflix have that option to use such thing?

Curious fact about F1 aerodynamics: the regulations limit the computing power of the CFD clusters they use. The limit is about 30 teraflops but the teams can trade off less teraflops to more wind tunnel time.

As someone working with semiconductors, I think the limit should be watts instead of flops to encourage competition in this aspect too.

I would consider it a cost center like a developer fixing a released bug. It's necessary maintenance and when done right results in more profits

This is another reason why everyone at a company should be a csr for a number of hours per month. From CEO to every developer.
Oh, cool: the 'do you have any better idea?' response.

yes, I actually do.

Blackmail is the attempt to coerce someone into doing something they do not desire to do by threatening with the exposure of information they do not want exposed.

How is that? better than:
To blackmail is to threaten to do something otherwise legal (usually divulge information) unless you are paid.

By the way, if I said that genocide was the killing of another being, and you said that was a terrible definition, I probably wouldn't complain if you didn't have another definition, you know, because genocide is pretty well defined (as is blackmail)
Look at what you wrote "I developed marketable skills, secured multiple internships". That does not read like school did that for you and probably you could do the same without school. How much of that CS101 was studying on your own time?

Finishing school is signaling that you are person that shows up in the morning for classes and puts up years of his life to do that. By any means I am hiring developer who is signaling that he is reliable and comes to work every day vs someone who is inconsistent.

The article does not distinguish between exposure to ionizing radiation and non-ionizing radiation, both present in fusion reactors. The non-ionizing neutron flux could change the chemical makeup of the alloy, making the alloy useless for reactor linings. Does anyone have more detail on the testing of this material?
> "whenever one of an inherently-coupled pair of actions is morally allowed, the other of those actions is morally allowed".

Why does that follow? I could understand it for actions you are morally obliged to do, but I fail to see why it follows for actions which are merely allowed.

A 6-year old boy is allowed to fall in love with his teacher, but she is not allowed to fall in love with him, so his love - even though morally allowed - can never be fulfilled. That is a perfectly fine situation, from a moral point of view.
Wow, how can you enforce a limit on simulation time?

And that's not by coincidence. Not only will extremists find anonymous people successfully arguing against their points in these image boards, but the moderators are giving their best to delete the worst posts and ban the worst posters.

There's nothing like that to be found in mosques. They're echo chambers.
This article inspired me to go and compare the Barack Obama and Donald Trump Wikipedia pages. It is layering subjectivity on top of subjectivity, but the treatment of Trump does seem pretty fair and the talk page goes into excruciating detail on any number of topics. The result being an excellent job done of finding references and characterising the situation with a careful and mature perspective.

I hadn't thought about it in that light before, but the highly partisan nature of the Trump Presidency does seem to have resulted in a level of quality that neither group of partisans would be able to achieve alone. Very encouraging what good editorial policy can do.
Is there a non-paywall version? I can't read this article.
Of course they would. They are a taxi service, not a Dropbox or YouTube. They do neither have obscene demand for storage, nor for bandwidth, they need some servers tracking their users coordinates, running a "who is nearest" search in case someone wants a ride, some GPS navigation/pathfinding during the ride and some billing code after it.

If you don't blow this up to stupid proportions, that should be able to run on modern hardware in a few racks at a colo for millions of users per day, especially since you can neatly shard the load geographically, thus distributing load (and rented racks) over multiple DCs, ideally with failover in place for emergencies. The only thing they really need to merge is the billing data at the end, but handling billing data of a global userbase of tens or hundreds of millions of users in a single system is a solved problem nowadays and does not even constitute a case worthy of the overused "big data" moniker.

It's more like, fascists and such come to /pol/ to post their garbage, and meet well-spoken anons that oppose their views and expose the flaws of their arguments.

This is an obvious advantage to all of this happening in the open, over it happening in some members-only curated hate forum where any voice of reason is just removed and banned.

I'm baffled with how irrational some people can get, irresponsibly calling for the suppression of public, anonymous image boards.
Just a small correction. It's not something proposed by me. It's a description of how things are at the moment, at least in the north of Europe.

The difference lies exactly in the details you describe. If an accident happens, you're not in the clear because you had "right of way", but because you, having good control of your vehicle, exhausted all possibilities to avoid the calamity.
Also not a US citizen and I don't know how it works at Princeton, but in my experience, getting actionable feedback on assignments is rare. You may get told where your mistakes are, but not how you should have done it instead. Most of the value of assignments is in simply doing them; that forces you to review the necessary material.

As for office hours, I never went to any, but I assume that they're not going to check your student ID, just as they don't check before lectures.

I think you should be a bit more open minded and critical. The point is that the energy required for exercise has been over emphasised and the relationship between calorie estimates and the energy that a person gets from that food is not linear. Therefore "fewer in than out" can end up meaning that you gain body fat rather than get rid of it. Conversely if you simply change the type of food (to unprocessed and uncooked) then your calories and exercise can remain static while you start losing body fat.

I always wondered about the downforce. If one design is few % better than another, providing the key advantage, does that mean the drivers are able to drive so exactly that they can use the extra force without spinning out?

Is there some sort of feedback when you're really close? I've only had a couple of track days, never came close to understanding it.

We use multiple schedules with Pagerduty, and when an escalation policy is triggered, it can route to multiple additional schedules.
So let's say you can escalate to an SME schedule, if a certain incident is not resolved within a certain amount of time.

They have a configuration tab for "business services", where you can set up dependencies between services, but we're not using that, so idk how smart is that.
I guarantee you they're already disengaged if that's the feedback you got. I don't see anything you can do to get the money for your team. You just have to accept it. It's a shitty situation. Your engineers should leave if they can and they absolutely should disengage if not. That's life. That's what's going to happen barring some miracle from the execs or whoever controls the money. The execs should also know this, but most likely they are psychopaths and don't give a fuck. You seem to be a caring manager who is stuck in the middle. There's a reason these psychopaths put you there and it's to act as a cushion between them and what they consider disposable plebs. I hope they're at least paying you decent money for it. The fact that you get things done and complete the explicitly stated part of your job is for the psychopaths just icing on the cake. Of course, when you don't because your entire team is gone or disengaged, they'll have no qualms about letting you or them go. C'est la vie. This is the position you pursue as a middle manager.
It's broken frequently over the years.

Ask HN: Remote Linux Environment
Hi HN,

I am yet again asking for your experience.

I am in need of a linux remote development environment.
Basically I just need a linux box on somebody else server with some disk space, enough CPU and RAM to run the compiler, and network connection to download stuff and to remotely connect to it.

Is there any service that does this for myself without me having to think about backup, turning off the machine when I am not using, storing volumens, etc...

All trivial stuff that need to be automated...

Renters also receive the benefit of the subsidy on landlord mortgages (that would otherwise increase costs to landlords which would tend to constrain supply).

The poor pay less in taxes. It would not surprise me to find that if you could trace the entire effects perfectly that poor renters are net beneficiaries of the policies particularly now that the owner-occupied MID has effectively been eliminated for houses on the low end and it was previously capped on the high end already.

Now, it mostly directly benefits landlords, which I’m sure is entirely a coincidence... (Our income tax system is based on taxing income/profits, meaning that eliminating business interest, including commercial mortgages, as a deduction is incongruous and a non-starter.)
Article was fine until this:

These behaviors make perfect sense if — and only if —
employers are eager to detect workers who dutifully
confirm to social expectations. In a society where
parents, teachers and peers glorify graduation, failing
classes and dropping out are deviant acts.

This is a misunderstanding. Employers pay attention to qualifications, e.g. on a CV, as an informational shortcut. If you don't get the qualification, then you are pooling with everyone else who didn't - including nonconformists, but also the incompetent and lazy. If you get the qualification, even only just, then you are in the category with everyone else who did, including brilliant top achievers.

Maybe employers do care about social conformity, maybe even overwhelmingly so - but this evidence doesn't show that. Looks like a journalist misreading the academic literature.

Adult learners are a demographic that could be highly motivated as you describe but often wouldn’t have any chance of getting in through the application process of an elite university.

I think this group is quite poorly served by our current system.
If you're making 50 euros per hour, couldn't stay in the Netherlands, so that you get to be with your girlfriend, friends and family and still work 3 days per week? I think 5000 euros per month should be enough even for the Netherlands. It's true that you would save less, but you would get to be with your friends and family.

Or you could just go to Thailand for a few months, so you also scratch the traveling bug. There's nothing stopping you from coming back when you start missing the people close to you. You have options.
For employed people the Dutch system is indeed awesome. When you run a business, it's still quite archaic.
