In a statement, Tencent said that the company did not store the chat history of users and that it would never use chat history for big data analytics. The comments were met with widespread disbelief: WeChat users have been arrested over what they’ve said on the app, conversations have turned up as evidence in court proceedings, and activists have reported being followed based on WeChat conversations.

Unfortunately, WeChat is so firmly embedded in social and commercial activities that it's very difficult to go cold turkey.

Nightmare scenario for people outside of China would be some sort of Facebook/WeChat partnership or acquisition. Note that Zuckerberg is very keen on breaking into this market, and has been buttering up Chinese officials and citizens for years to pave the way (see "Why would Mark Zuckerberg want Facebook employees to read the Chinese President's book?", https://www.washingtonpost.com/news/worldviews/wp/2014/12/08...)
This is a great point that a lot of people seem to miss (or just don't care). I do care because I don't like to worry about dust accumulating internally, noisy/malfunctioning fans, etc.

The Pacific Northwest used to have a lot more Aluminum smelting than it does now - the power was provided by large hydro power contracts.

Not sure if it was changes in these contracts or other market forces that caused the decline.

How We Built a Cost-Based SQL Optimizer
I'm guessing a lot of people aren't familiar with this recent spam.

They're using email/password combinations from lists of leaked accounts. I use a distinct email address for every site (qmail's scheme: x-foo@mydomain), and so the setup was very transparent to me. But I can see the technique totally working on a basic user who reuses passwords and email addresses.
I think it might be even more subtle than that. If I'm understanding page 9-11 correctly, they selected GA, HDG and ALT SEL (the correct settings) before entering the altitude, and doing it in this order caused the autopilot to switch to ALT mode. Then when they subsequently re-selected ALT SEL mode, this was ignored because the autopilot was in ALT mode. Nasty bit of UI design.
does anyone know if this or epigenetic inheritance only result from stress during the time the sperm were grown or whether sperm carry such information years after stress, which has now gone - i.e. if one was stressed over some interval in the past but is now happy and relaxed, does one's sperm still carry the marks of stress from the previous stressfull period ?
> How do we fix this bug in human psychology?

My gut feeling is that this sort of thing is cyclical. We oscillate back and forth in countless ways, micro and macro. So the bug fix is to ride the crazy train until we reach the apex and then keep riding it back down to “sanity”, overshoot, then do it all again forever.
"Then there are the work schedules. The Silicon Valley natives were introduced to the Chinese start-up concept of 996: Work from 9 a.m. to 9 p.m., six days a week. Once they got over their shock, they had to ask: Does that punishing schedule make sense? “I’m not worried so much about my portfolio companies not working as hard as the Chinese companies,” said Mr. Chan, now a partner at Felicis Ventures. “I’ll worry when they’re less creative and less efficient.”"

This is scary
That is typical usage but it isn't the required usage. It is straight forward to generate a controller ASIC that would provide the appropriate bus signals and drive levels for these to operate on a module.
That's why it's aggravating to me how many cities insist on building everything at ground level. Cars? Ground level. Bikes and pedestrians? Ground level. Trains? Ground level, creating chaos at intersections. And now we have tons of scooters. Ground level, and causing chaos as people ride them without helmets and weave into car traffic.

Adding more ground level transit isn't ever going to be the solution, and widening lanes doesn't ever seem to work. Cities like LA need to stop being bought off by the developers and instead build larger versions of these for non-automobile traffic:

I would counterpoint that it probably should be someone elses job to us force to get the mic back. I’m sure there are officers of some kind in that room.
Routers being the “bottom of the block” in a subnet is just convention. In fact I’d say someone with a router in the “middle” of a block probably knows exactly what they are doing.
No, that's her job. The problem is, if this was a physically imposing dude rather than a woman, he would have given up the mic handily. But instead, he ignored her position to distribute the mic (as appointed by the President of the U.S.) and manhandled the mic away from her.
1. That's just the gray fallacy. "Knowing only gray, you conclude that all grays are the same shade. You mock the simplicity of the two-color view, yet you replace it with a one-color view." Just because some cases are uncertain doesn't mean all cases are equally uncertain. As Asimov put it in The Relativity of Wrong: "When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together."

2. Let's set aside the heredity assumptions for a moment and go straight to the heart of the matter: As a proportion of the people who will be born in the next generation, would you rather have a larger or smaller fraction of them be poor for life? Why?

> MA1 (margin-all-size1) and MA2 (margin-all-size2)

Honestly these aren't too bad. But all the CSS frameworks I've seen of this style instead are like MA-10 (margin all 10- pixels) and MA-20 (margin-all 20 pixels) which of course completely defeats the idea of standardized steps beyond limiting you to that subset.

I think there is some value to a few of these styles in any project but ultimately you get more standardization with semantic names. "alert-danger" instead of "alert-red" for example.
So what you're saying is this is good for bitcoin?
No, I don't think this is a transition.

What we're likely seeing is M&A people caught up in the hype and trends.

In some ways, it's worth spending some amount as a hedge against something happening, but I don't believe these scooters will represent any meaningful change ... personally I think they are kind of a fad.

The logistics, cost, narrow use cases of all of it just don't work out well enough. Truly - what % of people could actually commute using these things? It's very small. Of those, who would actually do it? In winter? Up and down hills? Are they a little bit too old for this, or maybe not so open minded? Are there status issues, i.e. if you are a 'serious professional' in many industries it just doesn't bode well to be bouncing around on a scooter (I know this might seem foreign maybe to HN readers but this is a thing). And then of course - if it was useful for commuting, why wouldn't people just end up buying one so they always have it when needed? I think the use cases for these scooters is very narrow.

While I agree the general attitude of 'moving beyond traditional cars' is a strategic impetus, and it makes a lot of sense to 'participate' in these things early on ... I don't think this is a secular shift. Not yet anyhow.

America is a very spread out place - even LA.

And we're only just starting to see the regulatory and populist backlash.

Those aren't mutually exclusive. Object capabilities are a core part of what makes the L4s faster than Mach. Mach had to do a permissions check on every IPC message since the port table is global. And since it was global, practically that was an expensive ACL check. You don't even have to do a full permissions check on capability endpoints since the mere fact that you have a handle to it is proof of that you have the appropriate permissions.
When the POTUS is preventing the freedom of the press, he/she is not representing the people or the Constitution.
Oof, I had hoped nobody would take me on such bad faith as to claim I was saying that Jim Acosta, a single employee of a single news agency, represented the entirety of the 4th branch. This is disappointing. I'd be especially interested in a discussion with you of why you felt this was necessarily, offline via email if you'd like (in my profile is my email).

To answer your question - the press conference is the one (rare) chance that I get to have my questions, as Trump's employer, answered. I don't find it acceptable that the man living in the house that I pay for is dodging questions that really aren't even that hard. It's not like Acosta was asking for Trump's birth certificates - he was asking Trump to explain his vitriolic language and spending of my resources sending troops to the border.
Plumber probably is. The tech and tools used may change, but I can't see it going away.
This might be one of those San Francisco problems. In most places a combination of law enforcement and peer shaming would discourage cyclists from breaking the law.

Yeah and he spent like a full minute responding and talked about the difference between globalists and nationalists.
Yeah, there's a distinct difference between my yelling and my wife's yelling. Mine is calculated; hers is more emotionally responsive. That's one reason I escalate to yelling more quickly: because I want to be doing it as a rational response to a need for discipline, as opposed to an emotional response when I just can't take it anymore.

I've come up with a few catch phrases that have served me well. I'm personally somewhat noise sensitive and honestly don't like the cacophony that comes with children much. But the reality is that there's nothing wrong with kids making noise: they're just being kids. My dad's catch phrase was "children are to be seen and not heard" but I don't think that's really ideal for teaching kids to be reasonably expressive, so I've leaned on "That's enough." There's no moral judgment implied, but I've reached the end of my tolerance for that particular noise, and the kid(s) needs to stop doing it.

Kids are really quite dumb. They just don't know much about the world. They don't intuitively understand why certain rules exist, and that's ok, because they're young and don't have decades of life experience to lean on. When I ask them to do something, or ask them to stop doing something, their first response is frequently "Why?" I've been there too, kid. My parents would respond "Because I said so!" which I never really understood as a kid. As an adult I realize it's because they were trying to teach me a measure of respect for and obedience to authority, and I as an adult I also realize how important it is for kids to understand that, but I think we can do better. So my response is "Does it matter?" "Clean your room." "Why?" "Does it matter?" The kid is forced to admit that "why" doesn't really matter: they've been told to do something and they must do it. Once they admit that, I happily explain to them the reasoning behind the request. I'm simultaneously teaching them intuition about the rule and that authority matters. Best of both worlds.

I had to have a recent conversation with my 9yo boy about his response to me yelling. He gets really frazzled and basically crumbles if I yell too much or too loudly or too pointedly about something. Obviously as a parent I don't like this, in much the same way that my parents would say "This hurts me more than it hurts you" when they'd spank me. (I still don't believe them, btw, but I understand where they were coming from.) So I had to explain to him that there exist people in this world who will try to use their emotions to control him. They'll use their anger to make him do things he doesn't want to do, or make him stop doing things he ought to do. He needs to be able to respond appropriately and rationally in those situations. He needs to recognize their emotions for what they are, understand the underlying reasons for those emotions, and decide what to do in response. He needs to grow into a person who doesn't let other people's emotions decide his behavior. Yelling can signal disatisfaction, but it can also provide an opportunity for kids to learn how to deal with others' emotions effectively.

It’s a great story for a bunch of reasons, but what I would like to point out for this thread is how effective pitting ethnic and racial groups against each other in prison is at surpressing organized dissent. That’s exactly the tactic employed here with the virulent tribalism egged on by this administration.
I think we’ve solved the mystery here
No, I'm not.

Firstly, I recognize this is just one factor. I focused on it because it's one I'm highly familiar with, not because it's the end-all be-all. I've already pointed this out in multiple comments. We could also talk about educational opportunities or tolerance/discrimination, but those things either aren't as clear cut or would be more contentious to discuss.

Americans saying they prefer cars when you ask makes sense when you consider the other options are usually hilariously bad wherever they live, and where they've lived in the past, too. Give them an option where walking and biking and transit actually work, and suddenly many people find those options desirable. Just look at how many American tourists say they love the transit system in, say, Tokyo, when they visit. Americans mostly "love cars" because they've been given no other serious options.

Lastly, while many people may not think of it in explicit terms, they may nonetheless enjoy some of the knock-on effects of urbanism, like a city "feeling more lively".

It seems to me that your question is coming at this from the wrong angle.
Look, you wont find this in the towns with the absolute best schools, and it is only possible to have this sort of commute if you work on top of the lower manhattan path station or penn station. Additionally, prices could've have risen since I last checked, and property taxes in NJ will always be high. But towns ranging from Maplewood to Cranford fall in this price range. Note when I say sizable I'm talking the ~2000 sqft range also.

Chinese citizens have en masse been exploited by those in power for thousands of years. Moreover, workers and peasants weren't critical or even overwhelmingly supportive of the cultural revolution. Now China near the highest income inequality in the world and just like in the past those in power have technology in place to keep the average Chinese worker the ability to protest their working conditions. Hopefully, this will change but it is probably unlikely.

I'd really like to ask these VC's and corporate leaders "Are 12 hour work days 6 days a week where every movement of your workers are tracked something you'd like to see as a cultural norm?"

I think it is up to employees and entrepreneurs here in the US to push back against this march to longer and longer work days. Our physical and emotional health is far more important than a title or a few extra dollars. The well balanced life is a wealthy life.
This is absolutely true, from what I've been hearing NJ transit has just been getting worse and worse since I had used it on a daily basis.
>> At the same time, we are seeing Rust pop up in a lot of places that used to be the exclusive domain of C. People are already re-implementing libraries, popular command line tools,

> Yes, but some (e.g. ripgrep) don't actually do the same thing as the programs they are supposed to "re-implement". Most Rust "re-implementations" don't actually re-implement programs, they are new programs doing a similar-but-not-quite-the-same thing to the older C implementations. For example, ripgrep is neither GNU or POSIX compliant, and therefore it is not a re-implementation.

That ripgrep isn't GNU or POSIX compliant is indeed a distinction worth making, but certainly not in this context. You're taking on a very pedantic interpretation of "re-implementation" here that doesn't really matter to the general point. Specifically:

> At the same time, we are seeing Rust pop up in a lot of places that used to be the exclusive domain of C. People are already re-implementing libraries, popular command line tools, etc. A lot of these implementations have clear merit in the sense that they are faster, safer to use, easier to scale, maintain, etc.

None of this requires any of the "re-implementations" to be 100% strict bug-for-bug compatible tools.

This general confusion comes up so often that I have a FAQ item for it: https://github.com/BurntSushi/ripgrep/blob/master/FAQ.md#pos...
Right, we live in a capitalist society, so unlike say a communist nation we don't need to have an "agency of government transparency" or whatever that has the sole responsibility (and the only entity allowed to) of telling the people what the government is up to, we have companies that find a way to generate a profit off this service.

There are plenty other public goods entities that are also profitable - hospitals, for example, have to generate profit (though I disagree that this should be necessary). Energy companies. Airline companies. Etc.

In any case, CNN was there to ask questions on my behalf. I'm glad, too, because I like government transparency, and I for one don't trust any government to self-report without bias. Hence, auditors.
> Really, we are arguing over whether someone grazed the arm of a woman who reached to remove the microphone from a reporter?

I don't think so. The conversation has been about the WH press secretary's characterization and reaction to the event and, now, whether that office is pushing an account of the event that deliberately distorts the truth.
>>Why is this even being talked about?

-A major news outlet had one of their major White House reporter's press pass revoked.
-The President's press secretary cited a doctored/edited video as evidence of the behavior that resulted in this revocation.
-The President of the United States has been on a 3 year long campaign to sew distrust in media sources he doesn't feel portray him favorably.
-The President of the United States has blatantly and openly lied about information he felt was affecting his policy making, causing many people on both sides of the aisle to distrust his ability to objectively lead the country. This interaction occurred during a press conference in which the President was again repeating blatant lie, as well as the less offensive ignoring and misdirection of unfavorable questions.

Would you like me to keep going?
I think it's helpful if you come from a different culture where some of those things would be considered acceptable.
I think we need to have an agent centric approach. To view the world as a game, with a purpose, and the agent as a player learning to improve its game and the understanding of the world. Interactivity with humans would be part of the game, of course, and the AI agent will learn the human values and the meaning of human actions as a byproduct of trying to predict its own future rewards and optimal actions. Just like kids.
Congrats to the Spin team!
This reminds me of a company I worked at where they deiced people were spending too much on travel. So they came out with new rules about travel expenses every 6 months until large swaths of people simply couldn't travel (me included).

But the problem wasn't solved at all because the bulk of the absurd spending was caused by people who the rules didn't apply to....
