I have young children. I’m not trying to prevent my kids from intentionally seeking something objectionable on the internet; I’m trying to avoid them accidentally finding things they’re not ready for (this happens).

It’s rather amazing how hard this is to accomplish without locking them down so hard they’re using the net though a drinking straw.

Ways Engineering Managers Get Stuck
Free speech goes both ways. From the NYTimes article:

> Bill Burger, a spokesman for the college, said in an interview: “There are people who are eager to portray college students or the entire higher education establishment as hopelessly out of touch, a bastion of liberal indoctrination, and I think that’s fundamentally false. However, events like last night’s do feed that false narrative.”

Couldn't have said it better myself. They're only hurting their own cause.
If genetic boosting is actually possible and not fringe bullshit, it's way faster than socioeconomic fixes, which seem to take 10 years per 3 iq points.
I find it amusing that this first program in Go is for parsing an Lisp-style S-Expression, given that this has nothing to do with Go's syntax.
Also mentioned in sibling comment, but I was thinking more from the perspective of a company trying to accurately gauge a candidate's caliber. From the side of an interviewee, it definitely isn't a clear win; the only case where I think a candidate would prefer this would if they tend not to perform well in interviews (which I don't think is necessarily a good indicator of whether or a not a candidate would perform well for a job).

An additional perspective I didn't think of until now is whether this type of recruitment process would be more beneficial to the industry as a whole. An argument could be made that we'd all be better off as a whole if interviews tended to more accurately assess candidates and candidates were able to get a more realistic sense of the type of work they'd be doing for a company.
Evidence suggests that this market is changing rapidly. I have seen graphs on paid ride figures being pretty even over time, whereas standard taxi figures appear to almost universally be dropping in quantity. Might not a longer term perspective change a lot of this speculation?
Putting aside the driverless car thing for a moment, can't we at least agree for the next 3-5 years people are going to continue to require taxi-like transportation services?
Some people will ALWAYS want to have a driver.
> In the prior 17 years of professional experience, I have never needed to write a graph traversal algorithm.

I don't get this. I'm in my early 20s and have professionally implemented graph traversal algorithms at least five times. Graphs are extremely powerful data structures, and if you have them, then you can expect to traverse/search them.
Nope. Genetic engineering works far, far better. We've already plucked the low hanging fruit of adequate nutrition, early education, salt iodization, and lead reduction. Anyway, those reduce mental retardation, they don't improve the baseline too much. And the Flynn effect looks to be slowing or reversing. 50 IQ points is huge. It's the difference between a burger flipper and a physics professor. The change to the world when the average 5th grader is mastering chromodynamics is hard to even contemplate.
Agree. The best thing a business can do is standardize their hiring practices to weed out intentional and unintentional bias and politics. It is hard, though, but possible. Guess that is why I love working in a small business. We keep it transparent and real. We just want to hack things and work with good people.
Will they, for example, mark as "disputed" that the Ryzen is faster than a core i7? (No, as far as I can tell.)
> didn't like that Trump took credit for a hard and proven fact

Since you, yourself, note that Trump is trying to take credit for it, perhaps you should explain why their reasoning is wrong.

"The national debt fluctuates up and down depending on the day. While the debt is "down" after one month, experts say that trend will reverse and the debt will continue to rise.

This factoid is a gross misrepresentation of the state of the debt and the role the new president had in shaping the figure."
Isn't that dangerous ? This will allow him to have a normal life, which includes kids, which will need this (potentially very expensive) treatment as well.

Wouldn't you, in order to not destroy the gene pool, want to restrict gene changes to both of those ? Either that or sterilize the patient to prevent transmission of lethal genes ? This treatment is VERY unfair to any children this guy fathers.

Of course I do get that the method used here goes not really support germ transfer (that requires the gene change to happen in vitro)
A current shunt. There are modern energy monitoring ICs that sample voltage and current at high speed and accurately compute power and energy with switched reactive loads.
54 companies? That seems very inefficient.

I like Triplebytes [1] focused approach to hiring engineers. I think they used to interview candidates to assess their skills rather than depend on whiteboards or resumes. If the candidate passes the interview, they would be connected to relevant companies, take up interviews with the companies and negotiate the offer(s). Now it looks like they changed the process slightly to introduce online coding tests to make it easier to screen more candidates. Edit : As pointed out below, the online coding test is the first step followed by one on one interviews.

I have a few anecdotal examples of innovations or ways in which China is 'ahead':

Bike-sharing startups like MoBike: Use their app to find the nearest bike to you, scan a QR code to unlock it, and pay $0.15 for one hour. You can then ride and leave it anywhere. Admittedly, this is only possible due to v. high urban density (China has ten cities with populations greater than London and similar urban densities).

I can order a lot from the same app/interface: takeaway, cinema tickets, hotels, flights, KTV, etc. I find this more convenient than UK. Mobile payment penetration here is very high here too. Almost everyone pays for almost everything with WeChat.

Andrew Ng argues that AI progress in China is underreported due to the language barrier. I suspect this insight applies more generally to all the innovations happening here.

A-10 (CAS) and F-16 (higher up). Both around $20 megabucks to acquire and both about $20k CPFH. Tried-and-true. Battle-tested. The. End.

With the US MIC budget exceeding 50% of total (or 4% of GDP or about 7 next countries together), value for money is a far-off concept.

And, why not heavier-load drones (say pilotless attack helo or fixed-wing) with loitering capabilities? Reducing expensive pilot training and survivability apparatii would cut costs.

I have the same worry. Page downloads content as some encrypted binary blob, displays it using <canvas>, impossible to block advertising or copy text.

However, at the end of the day, content providers have to make their content available in plain HTML format in order for search engines to index it. If they did the above without offering a plain HTML alternative, they'd lose traffic from search engines. But, if they are offering that format to search engines, they have to offer it to us too.

(Okay, they could lock it down so the plain HTML is only available if User-Agent = Googlebot/Bingbot/etc and source IP is coming from Google/Bing/etc network. But, will the search engines let them get away with that? I would hope Google would refuse to index it on the grounds that their crawler is getting something very different from what the real user sees, but I guess that's their decision.)
If you're selling $5 bills for $2, funded by venture capital, are you really disrupting the dollar bill industry?

I mean, you are, in the dictionary sense of disrupting - you're messing it up. But in the Silicon Valley sense, this disruption is going to last right until the money runs out and then disappear without a trace. Uber will be a cautionary tale along the lines of Kozmo or Pets.com.
Germany did not make anything like that 'well-known' around the world.

Refugees have been fleeing for some time from Syria, especially when the war escalated. People from North Africa increasingly come to Europe, especially because the events of the last decade: war, collapse of order, economic problems, ...

Claiming that all these people come to Germany, because we imported or invite them is just a lie. The wave of refugees coming to Germany from Syria was especially, because no one else helped them, just when the war escalated. Some EU countries don't get enough help dealing with refugees and others simply refuse to provide help. In the past German politics wasn't very helpful either and the problem slowly escalated over time. But one of the root causes are failed politics of regime change in middle east and north africa.

1, 2 or 3 million refugees in Germany is not the biggest problem. The much bigger problem is ending the war in Syria, which is to a large part caused or fueled by countries like the US, Russia, Iran, the Saudis, ... If the war ends, many refugees could return home... which would take years.

A current probe.

You might need more then one probe for instance you might have one current probe that was accurate at a lower current but could not measure the higher current, and a second probe for the high current. Then process the data using the appropriate instrument depending upon the current.

I haven't done much w/ AC power measurements, but it's a common enough problem (large dynamic current range) for DC power measurements. Agilent (now Keysight) make instruments like the N6705B DC Power Analyzer that can sample a pretty high rates (like 10's of uSeconds) and be accurate at both uA range and 100's of mAs for dynamic current. I would imagine you could rig up something similar for AC power measurements.
From the paper:

The registered energy of the static meters was measured using an Arduino microprocessor and optical sensors for detecting the pulses from the LED on the static meter fronts. The readings were verified using the liquid crystal display (LCD) reading on the meter. For example, the LCD displayed 18 kWh, and the Arduino measured 17902 Wh, while on another meter the display showed 7.43 kWh, and the Arduino measured 7430 Wh. A conventional electromechanical meter based on the Ferraris principle was used as reference, because consumers are also using this as reference.
You may be interested in this earlier 2016 paper by the same authors:

http://doc.utwente.nl/102016/1/Runaway_energy_Meters.pdf

In this paper, it seems they were using an electromechanical meter (i.e. the analog style that predated digital) for reference because that's what consumers were using. This is measuring energy, obviously, not current.
A SilverSpring Networks meter were installed on our house in N. Cal around 2011.

Perhaps there should be some certification requirements like scales for trade?

> - requires you to give up 50% to a local partner

Chinese people. Don't worry, there's plenty. And they do not have subpar education, nor do they have less intellectual capacity (hell, most studies seem to conclude they have -just a little- more, on average).

> - blocks internet access to foreign websites (thus foreign customers)

I think you'll find that inbound commerce (or outbound commerce) is not all that restricted. Some movies, yes. And newspapers (do they still exist ?). That's about it. Other than that, it's not more restricted than in the west (ie. large amounts expenditures require government/irs/... approval one way or the other).

> - can take away your business/assets/customers without trials

It's not like Japan did it for 30 years before that ... By the way ... how did the US get started on it's industrial base ? Could it have been copying ?

> - treats foreigners as a mere entity to steal technology and clients from?

Again, one wonders how Europeans think about America in this area. Yep, similarly.

So, I've been curious: having a "worldline" seems to imply that the objects in question are a point object -- adding one dimension (time) to zero gives you one, a line. Is this actually a reasonable model, though?

If we think of particles as little spheres (or loops), it should be possible to knot them -- you can knot objects 2 dimensions less than your space. (Hence, there are 1-knots in 3D and 2-knots in 4D, where an N-knot is a N-sphere embedded.)

Is the question of 3+1D "anyons" actually settled, or has no one performed the analysis on the wave equation(s) looking for 2-knots? (My reading of MS papers implied the second, but I'm hardly an expert.)

Ed: As an aside, Im super happy Wilzcek is covering this. I've always found his writing to be rather accessible.

OK so serious question -- utility companies tend to have high-accuracy, company-operated/maintained meters (that effectively measure the total use of a bunch of customers).

They're meant for like, identifying non-malicious/technical losses but it's possible to use them to identify customers who are bypassing/tampering with their meters, as:

total use (as measured by the trusted meter) must be equal to
∑ accuracy(customer ID) * reported use(customer ID)

and assuming there aren't many cheating customers, and enough measurements (smartmeters make this easier, 15 minute slices is a lot better than 1 or 2 month slices), and assuming enough variation/independence between customers, it shouldn't be that hard to estimate the accuracy of each reporting meter.

I'm wondering if this sort of balance check (i don't know the proper terminology, this isn't my field of expertise, if you know more, i would love to be corrected!) would have been sufficient to detect the sort of misreporting mentioned in this article.

The problem is that Slack is designed for synchronous communication. However there is a huge need for a collaboration tool that is designed for asynchronous communication.

Being synchronous all the time means that you have no time to concentrate on cognitively complex work which is necessary for adding lots of value to your organization. Cal Newport in his seminal book of the same name calls this Deep Work.

Deep Collaboration is our term for collaboration that is asynchronous in nature and allows Deep Work to happen in collaborative environments.

Https://tmail21.com is a platform designed around Deep Collaboration principles.
Let me try to be more precise, I probably did a pretty bad job explaining what I really want to argue for.

I want to argue that whenever you think that there is some math already contained in the universe, it is actually you accidentally introducing it without noticing it. Look, trees! One, two, three, ... See? There are numbers in the universe. And look, I can add the number of trees in this wood and that wood.

It is of course tempting to conclude that the math was already there. But I argue that it was not, that it is you inventing it. It is your concept of object identity that defines what a tree is and when two trees are the same or different trees, you divide the world into different objects. It is your concept of grouping objects into sets. It is your concept of pairing the elements of two different sets to compare their cardinalities. It is your concept of including one more element in a set that defines what counting means. It is your concept of combining two sets that defines what addition is.

That are all things you can do with objects in the universe, but nothing of that is inherent. If you look carefully enough, all the things that look like math already exists in the universe actually require you making use of a lot of abstract man-made concepts. Many of them, like object identity and counting, are just so deeply ingrained in us that you don't notice that you are using them if you don't pay careful attention.

That is I asked for the empty universe, I wanted to take away all the objects on which you could accidentally impose structure. If math were truly fundamental, if Platonism were true, then seven should still exist in an empty universe. I don't see how this would be true in any meaningful way.

If we added a mathematician to our empty universe, he could invent math. He could come up with the idea of objects and identity and set of objects and he could think about operations with those objects and consequences of the definitions he made. But it would all have no relation to the otherwise empty universe, it would be a game of formal rules, mostly manipulating strings of symbols. If the mathematician had great imagination, maybe he could imagine actual things existing in the universe, how he could label them with those numbers he invented, and how he could visualize addition by moving things around.
Its high risk but the potential return is also great.

>Quick, name a language where I can do something simple like mention "Whenever this function is called, make sure there is enough free memory (at least ---- MB) before actually calling it; if there isn't, first swap out any objects from memory to disk, starting with the ones that had been used the longest time ago, and after the function has finished running, swap those back into memory."

The first fallacy is thinking that this is "simple" merely because it is "well specified".

The second fallacy is thinking that this should be the task of a language.
