To address "abuse by parents", I am not referring to physical violence. Abuse by parents in the sense that a group of parents can conspire to "punish" a teacher they perceive as being unfair to their child by not bidding on that teacher's class, potentially resulting in the teacher being fired.

The racial barrier doesn't mean that it has to be inherently racist. It can simply mean that, for example, white parents avoiding African-American teachers. Or vice-versa. A bidding system such as this could potentially result in an unintended segregation within the school.

In many school systems, there is already a "bidding" process among schools that put the good teachers at the good schools and the bad teachers at the bad schools. It is called school choice and allows parents to choose which school their child goes to.
How much do these VMs actually optimize with newer instructions? Last I checked (oracle java 8), the jvm still had really spotty autovectorization optimizations, and SSE has been around since 1999, with the most recent SSE4 coming out over 10 years ago. I get that they technically could do so, but how much do they do it in practice?

First reaction is that this would work well with ideal students and struggle (probably fail) with real world students. I principally say this not because the general idea is invalid (many online education and digital cognitive tutors are looking in a similar direction) it's just that young people are not good at self motivating when things are difficult (or when they have a more attractive alternative). Those super self directed learners will succeed no matter what, and this sort of program would probably work fine. The vast majority of students (even "good" students) do not fall in this bin. Your untrained hourly teachers may be able to provide such motivation, but there is significant value in the kind of relationships an experienced instructor can create over time with immature/reluctant/distractible/traumatized/hungry/sleepy/angry students.
If the last years have show us anything it is that the USA government (and others) can create the legality that they think more convenient.

For instance, you can invent a new category in order to avoid detaining people like criminals or war enemies if none of the laws applying to those are convenient.

Being good in politics does not imply avoiding conflicts. It implies effective approach to them. Most importantly, ability to diffuse the conflict and ability to find solution that satisfy multiple parties is not conflict avoidance - it is rational approach instead of emotional angry one. The direct angry confrontation is sometimes part of conflict solution too, if you have that kind of personality, but even there you need to control yourself enough not to make complete fool out of you - and know when not to do so. Which is pretty easy for angry people.

The other part of politics is understanding what other people are up to and why they are doing what they are doing. Knowing who can make decisions, who can be trusted in what, who is stubbornly refusing change and thus it is waste of time trying to convince him etc.

China has a long and proud tradition as being at the forefront of civilization, and they see the last 100+ years or so just as a temporary setback. The current ruling class may not see the need to share with the outside world. This may sadly result in the decline of China's competitiveness on the world stage, but those in the ruling class may be more concerned with consolidating their power within the country. This is not a new problem for the Chinese; it's just repeating the cycle of every dynasty that came before.

On a separate note, Whatsapp has been copying WeChat's features rather than the other way around for years. So perhaps China thinks they can innovate enough on their own to match or outpace the outside world. While I don't think that's impossible, I don't think they've taken into account how much the cultural revolution wiped out a lot of culture and collective wisdom built up over the centuries, and that will put them at much more of a disadvantage than they realize.

My father (economics professor) said you can date the start of a company's demise from when they build a palace for a headquarters.

For one thing, the design of the palace becomes a huge distraction for top management. Once they move in, they start to believe they are the godlike businessman the palace suggests they are.

If you're on AWS, a good solution is EC2 Parameter Store. Paired with KMS, you have encrypted secrets, locked down by IAM user if necessary. Paired with IAM Roles, you don't even have to have a key you manage for secrets access. You can cache a secrets file in S3, using the same encryption mechanism (useful if you want something like a .env.development to pull down). Most complicated part is bootstrapping your app to pull down the secrets, which is true of any secrets management solution you might use.
Filenames are not buckets of bytes. They're human-readable strings. Treating them as buckets of bytes is a great way to end up in very confusing situations, like having two files named "über.png" with no way to visually distinguish them.

This is another avenue that could be further explored, which I quite like. That is, a non-artist can doodle images and create a completely new photo-realistic image based on the line drawings.

I was modifying a few images (from link on another comment here: https://affinelayer.com/pixsrv/ ) and the end results were interesting.
Another factor is that Chinese data privacy is much more lax and platforms like WeChat that span so much of consumers' lives have unparalleled access to data which will prove to be major differentiation in the long term.
Ask HN: Best articles on how A/B testing is done in a large tech company?
Hi HN,

I am working for a large online retailer, similar to Amazon.

Are there any great articles out there on how A/B testing fits into a large tech organisation (i.e. as opposed to a startup, where it can be done on a more ad-hoc basis)?

I work in the IT department at a community college. One of the biggest costs we face is our ERP, Ellucian's Banner. I'm not on that team, but the number of times I've been interrupted by them talking about a problem in Banner is really really high.

AFAIK, the biggest reason there are no real competitors is that Ellucian does a good job packaging the law and regulation related stuff for financial aid. Apparently that's difficult enough that no open source alternative or non-open source company has been able to do better.

I'd love to see someone fix that problem.
Congrats David!

RE: your question about inherent privacy, there is Monero (XMR) and ZCash which implement transactional privacy in different ways.

In my opinion XMR/Monero are the only implementation to do it all the way through, so it's what I prefer but as with all things, you should research what the differences are and which is better for you. ZCash has a higher value per coin right now and is probably more accepted than XMR/Monero.
To date, less than half of the total possible SSNs have been used. They are not re-used at this time. (1)

1) I worked in a large hospital in medical information systems, and the edge cases of SSN included the (required) SSN for newborns and unidentified patients. For the former, we re-used the SSN of the mother, but added a suffix. (So in our database, it wasn't just a 9 digit integer, it was a >9 character string. I can't recall how long.) When the newborn got an SSN assigned, we updated it. For John/Jane Doe folks, we used something like all zeros or some such, with an 'auto-incrementing' character suffix. These were re-used.

That's just untrue.

I did no such thing.

> Edit: It appears you are that someone.

Nope. You're not reading my comments. I clearly said that alimony is deserved compensation.

I understand your frustration that people are taking a somewhat counter position. But the point here is to not blame you or to say you "deserve" to be poor.

The point is to have a discussion on responsibility. Why are people being compensated? How much should they be compensated? For how long should that be paid?

For me, if you're married for 2 years, and pay alimony for 50, that's abusive and wrong. Saying so shouldn't be interpreted as an attack on you personally.

Please learn to distinguish a discussion on the topic of alimony from a personal attack on you. There are absolutely not the same thing.

Now I've gotta watch, just so I can figure out whether the Klingons are racist (as in, the depiction is racist and the Federation's going all high-colonial Britain on 'em) or racist (as in, they're Trump supporter stand-ins), or somehow both at the same time.

These days, a store brand of clothes with respectable cachet is "Kirkland" from Costco. Basics like Kirkland jeans, underwear, sweatshirts, etc. I don't know if the kids like them, but a lot of adults wear Kirkland with pride. (Sort of like a billionaire driving an ecogreen Toyota Prius... an adult wearing Kirkland as a badge signaling "I shop at Costco which means I can afford Ralph Lauren but I'm smart enough to know that Kirkland is better quality for the money.")
I see your point, but using EnvKey also removes storing plain text copies of secrets as a default step in the workflow, so after you revoke an ENVKEY, it's a lot less likely that copies are still floating around. Of course, in the event that you're worried about this, you still need to assume that copies could have been made, so you still have to rotate any secrets that could have been exposed. EnvKey makes that process a LOT faster as well, and speed can be crucial in the case of a compromise.

In short, while EnvKey doesn't solve every conceivable issue with managing secrets securely, and still requires some common sense, I think it does offer a drastically better default workflow for companies that are currently sharing secrets on email or slack, keeping them in git, etc.
The health effects described are also similar to what you can get with a severe black mold infestation. Although if they've already taken apart the walls looking for electronic devices then presumably they would have noticed that.

Bernie proposed Medicare for All, but I haven't really heard anything about blocking mergers. Sounds more like effective DOJ/antitrust, though.

Keep in mind that Obama (widely seen as a sellout from Dems and the antichrist on the GOP side) was effective in reducing mobile subscription costs by blocking the AT&T / TMobile merger in 2014 - that was the FCC.
I used to do research in a lab which studied extreme temperature electronics using Silicon Carbide CMOS. These electronics are able to handle over 450 C ambient temperatures and may be able to survive in the Venusian atmosphere with minimal shielding. Looks like they started a company and have funding for jet engine electronics.

I didn't say anything about life ending at 30, in fact I'd say it is often the opposite. But it at least changes. I'm just recommending taking advantage of the things that easier when you are 18 than when you are 50.
Once people get married and have kids, men take on additional work to pay for their kids. Women take on less work to take care of their kids.

Women take on more work too, it is just not paid work. Mothers, whether they have a paid job or not, tend to be chronically short of sleep. Full time moms spend about 60 hours per week on household chores. Working moms spend about 40 hours per week.

I am aware that there are two sides to this story and men have their own concerns. But, the open hostility towards women you are displaying is something I felt a need to give a little pushback to. This is an overwhelmingly male forum. Such comments are often wildly upvoted and cheered on. It does not help bridge the gap. It just deepens the "war of the sexes."

But, I should probably disengage. Your pattern of comments here looks pretty toxic to me. Probably no good will come of engaging you further.

No, I didn't meant to say it was.

My point is the lines were easier drawn then - but not in 2017.

1950 was less nuanced. Black people were not allowed on TV, it was 'shocking' to have them there. An easy choice, in retrospect.

In 2017 - real social progress is complicated, it's not black and white. No pun intended :). I do not think that 'social progress' - in the populist sense, defined by the slightly-left-of-centre popular social voices - will have history fully behind them. Surely in many ways, but think it's much more complicated now.
Sears sold the Craftsman brand this year to Stanley Black & Decker (who also own DeWalt, Porter Cable, Bostich, and Mac among others).
> Of course at these scales a cluster is x5 slower.

So this complaint should be levelled at the papers and the academic communities- why is it acceptable to only provide empirical evidence for these distributed algorithms at data scales where they cannot out perform simpler implementations? Why not require empirical performance measurement on truly large scale examples for these kind of algorithms?
There is no such thing as a 'confidential email address'. The moment it is used by a single party outside of the owner the secret is out and from that point forwards you'd have to assume your 'confidential email address' is now a public email address. This is because of how email works. It's roughly the same as insisting your secret phone number stays secret. The only thing you can do with a phone number is not list it. But with every phone now having a contacts database and nobody using the phone book any more the numbers are all roughly equally public: they are known to all those you pass them out to and each and every service provider along the way as well as all applications with sufficient privileges on the devices that store your phone / email address owned by others.

By that reckoning confidential email addresses once used are no longer.

You do make me wonder if Troy's service stores the UIDs and email addresses or only their hashes. He wouldn't need the actual UIDs and email addresses to do the verification.
It's debatable.

Once the user has installed unauthorized software, the attacker can simply sit and wait for the user to expose more goodies (logins, bank data, 1password access, etc). In many ways, it is game over. If the attacker can leverage that to get your admin password, prompts are not going to save you.

Sort of. It seems to me though that once you've missed coins from many sources in various ways 90+ times then the coins are distributed in parts to many end recipients its then very hard to to say if some fraction of a coin came had any one source. If I were designing a way to launder cryptocoins that may or may not have a questionable source I think this is pretty much what I'd come up with.
I read an article about it many years ago. Who you bump into and are physically near can create and maintain certain workflows and company culture. This was probably more important before personal computers and the internet. You are likely to have lunch with people you see and different business units can cross fertilize with greater ease. Moving from an organically grown bunch of buildings near each other, to a huge building with only elevator access to each floor, will change how people interact quite a bit.

Just for context, Chinese made 122 millon overseas trips last year https://www.travelchinaguide.com/tourism/2016statistics/outb...

The censorship of social media is mainly to prevent collective action:

"The study showed that, contrary to western conventional wisdom, Chinese social media is as raucous and chaotic as it is everywhere else, so the Daily Mail’s idea of a country full of timid, faceless people with only banal opinions is baloney.

The study also revealed, though, that these outlets are ruthlessly but astutely censored: what gets taken down, apart from the usual suspects such as Falun Gong, pornography, democracy etc, are any posts that could conceivably stimulate collective action, even when the posts are favourable towards the government. You can say more or less what you like in China, in other words, as long as nothing you say might have the effect of getting people out on to the streets."

I'd also be interested in someone knowledgeable weighing in on the quality of those books.

My first world problem with somewhat random information dumps like that is usually that I don't really find that it's a lack of resources holding you back from learning about certain topics, it's a lack of time. The quality of those books really has to significantly eclipse what's available on the internet (especially in terms of presentation of the material) before it seems worth buying them (to be fair, price is not a real issue here, just in principle). For instance, I don't really see the value of software reference manuals (unless you already know the software and just need the reference, but then you would likely own it already and not buy it from humble bundle, right?).
Could be laundering but even with that you wouldn't want all of the source currency to be illegitimate so only a fraction of it would be. So it would probably cover both cases.
