> How do you know I don't understand math?

Because if you had a deep appreciation for mathematical structures you wouldn't be surprised by this development.

> And if a high schooler could figure this out, then Leibnitz own discussion or contribution to this topic is then meaningless?

Mostly, yes. Binary is useful for computers, but it's not like we use binary algebra in our daily lives. FWIW, Leibnitz did a much better job at calculus than Newton ... mathematical construct that has been "discovered" at least 3 times.

> The main point is that the finding in the article has cultural significance, rather than purely in terms of mathematics. I think you either don't understand that or are not willing to see that.

The OP was complaining about Nature screwing up the understanding of the mathematics and chiding the social scientists for ignorant remarks about the mathematics involved. I am also tired of seeing silly pop-science articles being posted HN.

> Could there an underlying commonality in the way humans learn and organize knowledge?

Yes, it does and this finding does not contribute to what we already know about mathematics and its relation to cognition [0]. I'm frankly a bit embarrassed by my social science colleagues and Nature for not doing a better job framing their findings more appropriately.

Sorry for being curt.

I don't think this is a new page on their site-- why is this suddenly at the top of HN? There's no new info here; this isn't an update or press release.
I'll own that I could see why you might think that I think a certain way but consider that we do not disagree? I pointed out that - with a premium on billing efficiency - the linchpin the product's actually delivering value in such an environment would still rely on (what I note as) _the assumption that_ a semantic+graph -based product does in fact cut down research hours, compared to the boolean-based approach.

Your explanation about the value of exceptions to rules in research is correct and would occur to, say, pretty much anyone who has drafted a motion (worth clarifying: not a drag on you). Far from a disagreement, the truth of this premise is why - as I pointed out - the most experienced/valued appellate drafters effectively rely on boolean. (Except, I guess, the 'within' operator might count as a semantic operator. Although that's been in lexis and west for as long as I've seen them, and I suspect have found immense use for much longer than that...)

edit: Adding that of course only one of the two following premises need be incorrect (firms should use products which enable them to spend less time on research; the citation graph enables lawyers to spend less time on research while yielding identical quality; firms should use citation graph -based products). Depending on your circumstances, only one may in fact be wrong.
LiDAR doesn't work well in rain and it's just a ray of infrared laser light scanning surroundings, so it can be obstructed the same way as cameras; radar is what you want. But NVidia uses just 3 normal cameras and deep learning to drive in rain/snow/night and it seems to be working for them.
> At the time (I was s cashier) WF culture was dead set against self checkout stands, because they really wanted someone to be there to help customers.

As opposed to having longer checkout lines? How about investing in a non-shitty self checkout stand?
They didn't advertise that all Teslas are capable of self-driving, they just say that the hardware has the capability. They're specifically speaking in computer terms, even - I wouldn't expect that buying a computer advertised as having the hardware to run <game> at 120fps would include a copy of that game.
If anyone isn't aware: While most companies use LIDAR, Tesla uses radar

You can't make a physical model of the solar system that has the axis outside the surface of the sun because if the radius of sun and planets was in the correct proportion to the distances of the planets, they would be too tiny to see. Nor would you see the microscopic offset of the axis. If the sun was grossly oversized compared to the orbits (as it usually is), then the tiny offset of the center of rotation would still be visually indistinguishable from being at the center of the sun.

Sure, but I can't imagine every clerk who signs up for the job stays there forever. Even a 15%-25% attrition rate would allow the company to invest in automation without having to resort to layoffs.
German system does not measure IQ. They split children based on second, third and partly fourth grade grades.

There is a lot more then IQ that goes into grades. All of it happens before 10.
From "Surely You're Joking, Mr. Feynman!":

"While I was doing all this trigonometry, I didn't like the symbols for sine, cosine, tangent, and so on. To me, "sin f" looked like s times i times n times f! So I invented another symbol, like a square root sign, that was a sigma with a long arm sticking out of it, and I put the f underneath. For the tangent it was a tau with the top of the tau extended, and for the cosine I made a kind of gamma, but it looked a little bit like the square root sign. Now the inverse sine was the same sigma, but left -to-right reflected so that it started with the horizontal line with the value underneath, and then the sigma. That was the inverse sine, NOT sink f--that was crazy! They had that in books! To me, sin_i meant i/sine, the reciprocal. So my symbols were better."

And some example here: https://tex.stackexchange.com/questions/274463/feynman-trig-....
simple solutions are things like making separate ventures be actually independent. For example spinning off IE as a separate, independent company from Microsoft. One that would be free to make deals with other OSes.

Imagine if Apple bought Intel. It would be extremely likely that Intel would be forced to continue to sell its products to everyone, even if theoretically Apple might want to just stop shipping the parts to competitors.
We are asking a brand-new technology to catch up with stuff that has had an entire industry optimizing it for decades. It's going to take decades for a single company to get things up to speed.

Compare Chris Urmson's SXSW talk from 2016 about Google's system.[1] Look carefully at the graphics which show what the sensors are detecting, and compare with Tesla's. Watch Urmson discuss hard cases, problems, and failures. Not seeing that with Tesla. Or Uber. Or Cruise. Or Otto.

Thinkpads have been water resistant for many many years now. Recently, this video[1] shows coffee, wine, water being poured on a T440s without problems. The thickness of that laptop is 0.8in. This laptop comes with 2 separate replaceable battery so you can even hot swap them.

Recent thinkpad X1Cs are only 0.65in and have user serviceable batteries via just a couple screws. So it's definitely not a crazy hard feat to pull this off.

Granted this is not a waterproof laptop, it is simply water resistant (no dropping into the pool). However, that seems to be what you're asking for in your original reply. The only question remains what you believe to be "substantially thicker than a modern smartphone".

It doesn't matter that most people going through the USA have no issue with US Customs.

What matters is that nerve-wracking bullshit like this[1] happens to people (little old ladies!) from allied bloody countries.

Mem Fox is a celebrated Australian author of childrens books.

She later received an apology, but only because she's famous. Tough luck to the average foreigner who gets abused by your border agents.

This is why the US is hell bent on spewing negative propaganda about China and Russia, because it needs to hide the fact that it's a huge embarrassment to itself.

Does Mars have much atmosphere to speak of? The figure on Wikipedia is that surface pressure is a measly 0.6% of mean sea level pressure on Earth. And there's no magnetosphere at all.

Nope. Once I start typing the code simply flies.
> I disagree. With opportunistic encryption, if the recipient' server supports STARTTLS, then the communication between the sender' server and the recipient' server is encrypted using TLS. Nowadays, all major email service providers support STARTLES.

With regular passwords via a browser, you can ensure the channel is encrypted via HTTPS.

Opportunistic encryption is exactly that: it uses encryption if it can, but will fallback to unencrypted if not.

How is "sometimes encrypted, if its available" not less secure than "always encrypted, unavailable if encryption doesn't work"?

> Just use the GMail to avoid the delay with fetching third party accounts.

So, you're simultaneously suggesting that everyone use 'email links for login' and suggesting everyone use a single email provider? Sure, that doesn't sound terrible at all.

> most users don't use a password manager

What's your basis for this? Every browser in use today has a password manager built in. People promoting these bullshit "not a password" alternatives always claim "average people" don't use password managers, but never present any evidence of that.

> If the user uses an email server that doesn't support STARTTLS, then theoretically an attacker could request a password reset and "catch" the unencrypted email.

Firstly - the main security concern with emailed 'login' links isn't the transport at all - it's storage/accessibility via the mailbox. Breach the mailbox, and you've breached the third party sites. The part people always ignore when suggesting emailed links as an alternative, is that if an attacker breaches your mailbox, they could conceivably use that to access your third party service that uses login links, and the victim would never know, because there is no password being reset, no killing of previous sessions.

> My conclusion: Passwordless login is an interesting solution. But there are other issues to consider, discussed in other comments (email delivery latency/greylisting, ergonomy, need to remember which email address you used, etc.).

My conclusion: password-less login is a thing that exists via public key cryptography: see ssh, TLS client certificates. Emailing links to people is nothing more than a fucking stupid idea, and frankly it's ridiculous that your "other issues to consider" makes literally zero mention of any security concerns.

The dash cam videos would be correct, outside of high-occupancy lane (2+ people) there are no lane speed restrictions, and if someone feels like getting into the left-most lane and driving 5 miles below the speed limit, they most certainly act on that impulse.

As you can imagine, anybody intending to use the left-most lane for high-speed driving is now forced to use the brakes, execute a [rarely safe] lane merge to the right, pass the slower vehicle on the right, and then aggressively execute a merge back to the left.

I've come into large python2 projects which had been started with non-unicode strings (because the initial developers didn't think about it). At some point a user with non-English characters invariably signs up and then shortly complains. It has been significant work to (1) convert everything that should be converted to unicode (2) re-train the developers to use the unicode syntax.
How do you think a ship is going to power a continuous acceleration? 1G for 4 years is... I don't really know, but it's a heck of a lot of energy even if you've somehow beaten Tsiolkovsy's rocket equation. You don't get to hand-wave this away in a remotely serious conversation. There's also the small problem of the interstellar medium wrecking your hull at high velocity, if you ever get there.

I wouldn't be surprised to see AMD release an APU SoC with HBM memory built in, a step closer to an entire "computer" being a single chip.
China can't steal all of that IP if we release it to the public first!

Just kidding of course, this is great news. The EU should still be the main beneficiary of open access science following this policy.
Not explicitly stated anywhere on the page, so let's be clear - this will only do 2 layer PCBs (top/bottom copper), correct? Also, what can it do without any "addons"? It looks like an addon is needed to do anything useful (etching, drilling, pick&place). What am I missing?

I reckon anyone willing to spend ~€3000 on hardware will be designing significantly more complicated PCBs than this will be capable of making.

Visiting and colonization are points on a spectrum.
Thats the thing.. A lot of westerners seems to think Chinese state apparatus are super ideological communists bent on catching anything that has a slight smell of democracy.

If I were to sum up my personal experience with Chinese gov. officials, I think "apathetic", or even "lazy" would be a much more apt description.
The airplanes of this world demonstrate this.
The author is the IT security person for the Linux Foundation, who's activities include distributing the Linux kernel via kernel.org. They represent a particularly juicy target for nation-state actors, and have been targeted with reasonably advanced attacks before. In 2015 the author published a checklist for laptop security, this is just an extension of that, teaching people (and LF employees) how to comply with their policies and China's.

Are they likely to be hassled at the border? No. But if there's a way to make all parties happy, might as well document it.
No, we should stop organizing conferences in countries where it is not legal to bring encrypted devices for personal use (like China, according to the beginning of the article), or countries where there have been known cases of pressuring travelers to decrypt their devices or of confiscating the devices (like the US).

How is it reasonable or courteous to require your conference attendees to read a long guide, buy a throwaway laptop, set it up, etc., or run the risk of being requested to decrypt sensitive information at the border or have their devices seized?

Just because the US and China get away with this does not mean that all countries do. Just pick any state in this list http://www.wassenaar.org/participating-states/ that doesn't have a history of requesting decryption or taking traveler's property without good cause.
What the article doesn't mention is remote workers are less often promoted. It's psychological - out of sight, out of mind. By default coworkers don't see you, only when you say something. In an office a manager will often pass by, and just by noticing someone will have a random thought about him. Like, "this guy has been doing really good recently, he deserves a promotion". I'm saying that you have to work harder to establish the same level of presence. You have to make an active effort you make yourself visible.
Since you mention Asana your probably interested in the task-management side of org-mode. I know people simply check the documents into version-control. Whenever you've done a pull, your task-list has been updated as well. I know someone also made an integration for Asana, but I'm not sure how stable it is
How did that work out performance wise? I was on an adsl connection in Beijing. Inside the country it was really great, could max out the 100mbit. Foreign websites were a pain. I found that ingress traffic constantly had a packet loss of 30%, which made TCP really unhappy, including ssh tunnels. Ended up writing my own tunnel software that was tuned to cope with the network situation.
Otto is Uber now ;)
I think so too. I've extended this frustration to airbnb and to zoning laws. How can they tell me what I can and can not do with MY property? That's insanity! If I want to rent it to different travellers every week, maybe I will find a way to do it, and maybe people should mind their own damn business and stop telling other people how to mind theirs.

Sovereignty goes hand in hand with property
For the record: this type of debt-slavery job is in large part what led to the rise and power of labor unions in the US. If you're reading HN and are a US citizen, you owe those early organizers for the fact that your life isn't like the life of these truckers.
The author's post is less about smuggling democracy into china and more about avoiding newspaper headlines like 'kernel.org pwned by national actor'.

Because when you buy software, you know you are renting it - you technically can reverse engineer/decompile, copy, clone, resell - but you know you shouldn't.

If I buy a car and want to take the engine out, or a light and resell it - I would be very stupid, but, it is my property and I should be able to.

If Tesla want to lend instead of sell you something - fine, just be honest!

This is very useful for quick prototypes. 2k is no money for a company on a tight deadline.

At DIY level however there are already multiple open source projects doing this for a fraction of the price.
I don't get what's the disagreement here. Apple sells you a whole system, iPhone + iOS. They don't sell you two things, like in PC world, for example, and that's different and that's okay as long as everyone is upfront about it.

What I am saying is that Apple sells you a product. You own it. You can do whatever you want with it. Feel free to alter any part of it, just don't expect it to work or keep your warrantee. The fact the product has limitations out of the box is a different matter. (Kind of like no one complains that kitchen timer can't boil water, or doesn't have nanoseconds precision — you want those things, you buy a different thing or make your own.)

What Apple doesn't do is to restrict you in how you use their product. There's no such thing like "you can only non-commercially photograph your family" or "never resell your iPhone", or "detaching screen is illegal".

And, more importantly, there is nothing Apple can do to stop you from doing any of those things.
I missed that bit. I see where he mentions the missing PUE, but that's not the same as outlawing the export of encryption.
I live here and it doesn't seem vague at all. It seems to basically mean no riots, large protests, or attempts to overthrow or weaken the government. We don't have a democracy so there's a risk that if large enough groups of people get too worked up, they might create a massive problem like a revolution or something. Nobody would benefit from that - see the mess it made in Syria, Egypt, Lybia, and Tunisia. In a democracy, there's no such risk because of the safety valve of angry mobs being able to vote their opponent out of power. But in a one-party system, it's necessary to limit the spread of dissenting ideas.

So as long as you're not doing political activism, it's fine. I know people who've had private messages apparently censored when they contained anti-government ideas. They don't get arrested. It's not something to fear. The tech companies just monitor and delete politically risky content. If you are a real dissident, then you know you're breaking the law, however vaguely it's worded, and you know you're in danger.

I'm pretty sure you are just mistaken in that assertion. There are experiments we could do that would validate it ... but it allows for FTL communications and thus breaks causality. It might be like string theory in that there are extensions which you can't rule out....

Bohmian Mechanics is a pretty garbage theory, it was literally invented as a way to show that the math could be done in a certain way. It's only been of interest to fringe theorists and in pop-science venues because it preserves notions of discrete/continuous space in exchange for violating causality. It might be easier to imagine time-travel than throw away human notions of physical reality, but the universe doesn't care about our puny brains : )
Ask HN: How do I grow my IT training business
Hello,

I'm a freelance trainer specializing in high end subjects such as Devops, Agile Software, Blockchain and Cryptocurrencies and Python application development.

I've been going through third party training companies to generate business but I'm finding that the amount of paying work being generated is erratic and not as plentiful as I would have expected. I'm looking for alternate ways to generate training revenue.

A quick background on me. I've been in the IT field for 25 years and have taught at major financial institutions such as Morgan, Stanley, Citibank and the New York Stock Exchange. I've been training for over 15 years and have worked all over the world.

If anybody has any suggestions on how to grow my business, I would be grateful to hear them.

Thanks
