I greatly desire a fun method of personal transport to get around to the shops, to work, etc. I don't want to sit in traffic, and I feel biking isn't safe when there's distracted drivers on the road.

So, I was pleasantly surprised to learn that jet packs actually exist in real life. Unfortunately, they're very loud, have a very short range, and are $275,000 USD. They would probably be regulated like cars some day.

So I guess it's just a dream until some cheap form of quiet propulsion is invented. It takes a lot of electricity to put even a 120lb human in the air for a few seconds!
I switched to Dvorak about ten years ago then switched back about five years ago. I switched back because I use swipe text input on phones which works much better (only?) with QWERTY, and swipe text became and still is very important for me.

Although I could type faster and much more comfortable on Dvorak I regret ever making the change, I feel I am still not as fast on QWERTY as I was before I switched to Dvorak. I make a lot of mistakes typing now and can't seem get much faster or more accurate with practice.

It was very difficult for me to do both or switch between the two - I was much better at Dvorak until I gave it up. My QWERTY was prbly 30 wpm max while using Dvorak. It helps to switch context or use different keyboards for switching. I think I got to 90 wpm Dvorak, QWERTY is now around 65-70.

I have problems typing comfortably and motor learning / coordination issues that might make me unusual, but I have read that fluency with both is rare and very difficult.

Oh shortcuts were more annoying in Dvorak, only other issue aside from swipe text.
No. You're turning people into serfs for the better part of their adult life for a decision they made as a teenager. That's not justice, that's cruelty.
> However, I do not feel that people who majored in, say, English ... should suffer because of the debt they incurred.

Why shouldn't they face the responsibility for the decisions they made?

That's the crux of the argument, really. Either people are forced to be responsible for their actions or they aren't...doubly so with student loans since they never really go away.

And I'm saying this as someone who got a "worthless" degree (back in the '90s when college was reasonably cheap) and has been in default on one of my loans for well over a decade but has never once asked anyone else to "suffer" over my decision to party, err...pursue a degree without a clear career track. Sure, it would be really, really nice if the good taxpayers subsidized my slacker lifestyle by forgiving my loan but I'm not holding my breath.

What about pose estimation? e.g. Given a well defined coordinate system, like the origin is the nose on a face, determine the pose of the face. Is this still best done with classic optimization formulations like ransac/ICP and a supplied model, or have these been bested by learned models somehow?
I would put Debian Testing on that list. Although it's called "testing", it's at least as much stable as Arch and very suitable for the desktop user, Debian's "edge" release is unstable (codename sid).

I think fixed wireless will take a chunk out of wireline in a few places such as urban areas where many customers are in sight of a millimeter wave tower but also exurban areas that are a mile or two from the end of the cable line and are underserved with slow DSL. AT&T, Verizon and T-Mo all have substantial amounts of UHF spectrum and could pressure Frontier and other bottom feeders.
> invested in an activity

Odd phrase. "Invested" in your own amusement? And that trumps others' right to be in the same place? The ones with "skin in the game" are the residents, owners, and/or official caretakers. If they want to let the unwashed masses in, as seems to be the case, who are you to overrule them? Instead of trying to exclude people, maybe we should educate people about what not to do and why not, providing facilities to contain the damage, hiring personnel to enforce rules and/or ameliorate damage as much as they can, etc.

I've been an active hiker, occasional backpacker, etc. for many years. Longer than most HNers have been alive. I've seen plenty of the damage that crowds can do. But I still realize that turning public places into private preserves for the most privileged is not an acceptable alternative.
I switched to Dvorak in a weekend (~8 hours) using something like https://learn.dvorak.nl/

It took me about a month to get comfortable and stop making mistakes and I switched back and forth regularly for the first two years (working in IT).

Now I mostly use Dvorak and when I switch it's not a problem but my typing speed in Qwerty is about a third slower.

Having done it, I'm happy with it but I probably would have learned Colemak instead because it's closer to Qwerty and would make those infrequent switches easier.

I would like to add more questions to authorcolle's:

How many qubits are for error correction, and how many usable qubits would you get?

Is it commercially viable to buy one of these machines, or are you better off just using Google cloud or similar to get the equivalent amount of computational power to solve problems that are appropriate for quantum computing?
> College is still probably a good deal the majority of the time I think, but I wish there was some acknowledgement that it is less important in some fields than others.

I'm certainly not advising you what to do - I don't know you at all and you didn't ask - but speaking generally about the issue: I think the unstated premise that college is vocational training for careers is very misguided. College is the acquisition of knowledge, of cognitive skills, and of a personal foundation for life, and life is so much more than career, and you'll probably have several careers. In fact, I'd argue that if you are using college to train for a specific career, you're wasting college. The world is so much bigger than Python or JavaScript, or even than computer science fundamentals. There are so many more issues, so many great thinkers and ideas to learn from, and so many critical thinking skills to acquire, 4 years isn't enough.

IMHO, theory is worth the time, a much broader understanding of the world is worth the time, JavaScript you can learn outside of college.

Sometimes the asker is wrong in what they’re asking, or barking up the wrong tree. In the example you give, unless the C++ Standard Library has changed since I last used it a number of years ago, a strict interpretation of your question gives the answer “You can’t;” the person suggesting Boost was trying to be helpful without calling you out as asking an unreasonable question.

The person asking a technical question should always include the goal they’re actually trying to achieve, not just the technical step they think they need to accomplish to get there. Otherwise they won’t actually get the best help possible.
There are opportunities in bull and bear markets. Also, has the $SPY ever gone to $0? If you have the belief that it will, well, when that happens, we are all screwed. No point thinking doomsday.

But let's step back and calculate suppose you got into $SPY in 2007 at 155. If you had kept the $10K in there, it would be worth $20K today almost. However, if you had kept adding money to it each year, your return would be massive. As you get older, you move from more index holdings to bonds, which guarantees you to hold your money. Another method is dividends, if you had AAPL shares, suppose 1000 shares @ 0.50 per quarter, that's $2.00 a year on 1000 shares, $2000 a year. If you had a family member who doesn't work and owns all the shares, in Canada, that would be up to $60,000 each year you can earn tax free.

I don't hold any stock, although I believe it is safe to do so, I currently only own 2 shares of TSLA as I wanted to be eligible for the class action lawsuit if there ever was one. I only trade options and I believe that is the safest way to make money and never go bankrupt.

Also, if you buy stock you can also sells calls/puts against your shares to protect you from a downside/flat days.

To reiterate, the statement above, is always easy to make, because this is the only way to make money. If you don't get into the market, then each year your money is running away from you, see inflation. Ally savings accounts just aren't as helpful.

Hopefully I have changed your mind and you will start looking into Vanguard funds at the minimum.
I've wondered about this for a long time. Can you be a republican and be considered virtuous. Not sure why my comment was downvoted, I am not suggesting that this is that case, just asking why its not case.

I am not an American but the way I understood American politics is that Republican values are believing that you are successful because you worked hard while democrats are that you are merely a product of the zeitgeist. All the policies of each 'side' can be extrapolated from that basic tenet.

For example, if you are a republican you favor slashing funding for social programs(eg: McCain's bill to slash funding for military medical research funding, slash funding to amtrak ).

can you still be considered virtuous if you are republican?
I was referring specifically to the parent's concerns. Fuel disposal is certainly a problem in nuclear in general. I'm not sure about this specific reactor type; it's possible it produces less-troublesome waste, but I don't know. Most power generation is exceedingly bad for the planet in one way or another, but nuclear is certainly a whole lot better than fossil fuels.
The Mafia also says that you have to pay them protection money. Just because they have the power to force you to let them doesn't give them the right to do so.

I'd hope an empty electric truck is light enough to pass the weigh station check. Else it would be useless when loaded.

> No truck, not even teslas, carries a braking system or air system with enough power to stop a downhill tractor trailer without shifting to a lower gear and employing the engine to help some.

A drivetrain that size should have impressive regeneration supplementing the mechanical brakes. Apparently this is about equal to engine braking in gas trucks. Though these trucks were empty.

Have we seen a fully-loaded Tesla truck yet?
The comment section on the story about this on Foxnew.com [1] is eye-opening.

> I don’t think other companies are doing 40.

Maybe I am just lucky but I have worked for 2 of the major big tech companies and came out of college making 100k+ while primarily working 40 hour weeks at both.

> 75% (45/60) of 150k

Tesla new grad software engineer total comp is 150k? Damn, in that case they are pretty close with big tech (amazon is 145k and G/FB is 165k from what I have heard). I assumed it was lower since my brother was a PM with 6 YOE and got payed 130k a year.

> That’s damn fine compensation for someone fresh out of undergrad even in 2018.

Oh totally, my girlfriend is probably going to make like 60k out of grad school. However, while it is much better than anyone besides what my finance friends are making, that does not mean they are paying well relative to the tech industry.
>I dig that it's a few extra lines of code, but I guess I'm looking for a really mean example.

>>> I've never known anyone who couldn't get a loan, no matter how bad their grades or weak their employment after college looks.

Student loans are risk free for the lender and very profitable. They will always be granted.
Don't think it's exactly what you're talking about (I'm sure there are other works much closer to what you have in mind, just can't recall off the top of my head) — but you might find PoseNet (https://www.cv-foundation.org/openaccess/content_iccv_2015/p...) interesting. Not explicitly 3D, but estimates where in a large-scale scene a picture was taken using an end-to-end convolutional network.

With that said, I think there's still a ton of merit in classical geometric approaches like ICP — there's a real, geometric basis to why they work. Convolutional networks can demonstrate some pretty amazing results, but they're still mostly "black boxes" to us, and a consequence of this is that it's hard to understand why they work and predict when they'll fail. This blog post (by the PoseNet author, actually) articulates the viewpoint well: https://alexgkendall.com/computer_vision/have_we_forgotten_a.... One recent research direction that I personally find really fascinating is designing deep learning architectures around real geometric properties, e.g. as in Skydio's deep stereo work: https://arxiv.org/pdf/1703.04309.pdf
Id say the game is rigged from the get go. Between age 18-21 we say that people are not responsible enough to even buy alcohol, but apparently they are responsible enough to sign up for loans that take decades if ever to pay off. Then on top of it weve made the loans impossible to discharge under any circumstances _and_ we have an entire system that tells children their entire life that you go to college or you will have a terrible life. How is any of this not rigging the system?
> Journalism aside, what is the reason? Are railways really that inefficient?

Most likely they (are forced to) cross-subsidize the non-profitabele routes from the profitable ones like Berlin-Cologne. Unlike national railways, cheap airlines can choose which routes they want to serve.

In semver versions before 1.0 are prerelease versions.
1. The money is in the form of a loan, which by virtue of our fractional reserve system, is created upon signing a promissory note. This is the basic form of money creation in the United States. Repaying the loan extinguishes the principal balance and "destroys" that money. However, interest owed remains and the debtor must "seek" out that money in the economy (which, consequently for many people, is in the form of another debt from some other person or company).

2. An economy where a major portion of debtors are unable to discharge their loans (due to the laws presuming student loans as ineligible for discharge), debtors will fall into a cycle of inability to pay debt, inability to qualify for a home, apartment or a vehicle, and potential inability to qualify for a job (credit check) and become increasingly dependent on government programs to stay afloat. This can put a strain on government resources beyond what a simple bankruptcy would do, which is the forced cancellation (discharge) of a debt. Basically, the cost of a bankruptcy (to the economy) is smaller than the cost of an otherwise capable judgment-debtor on welfare/Medicade/SNAP/others.

3. Private student loans, which are effectively no different than unsecured debt, should be presumed dischargeable in bankruptcy. Federal student loans are actually structured quite nicely, except many debtors do not understand the complexities of the multiple forms of loans they carry (perkins, plus, university-managed, subsidized, unsubsidized, private) and rules for one loan type do not necessarily apply to the other.

Colleges would actually benefit from student loan reform, since they could better educate students and parents on standardized loan packages, rather than the large array of loan options available now.
Honestly just a better package manager could work. Apk in Alpine is lean, pretty easy to build packages for, and works.

Alpine is the best distro today, at least for servers.

>It's pretty difficult for generics not to adversely affect compile times.

Compared to what? Non having type-specific code?

Because if you manually write (or use code generation madness as some propose) that type specific code you need yourself, then the compiler will take the same time to compile it as if generics were a language feature.

Economic's and economists' record wwith historical data and theory is an exceptionally poor standard to follow. (There are some exceptions to the rule.)
When it comes to society level discussion it seems that it is often assumed that people make irrational decisions. I am not sure that is true. For a lot of people it makes sense to take a chance on something unknown rather than to face likely failure. That is presumably also why they think the game is rigged. Because if you ask the average person who didn't go to college they probably aren't doing particularly well either.
My Camry Hybrid has a 500+ mile range. It says "585 miles to empty" after a fillup but usually gets 540-550 miles in mixed driving. Maybe gas-only cars will someday have range anxiety.
My loans were based on the LIBOR rate. That rate was shown to be manipulated by many banks[1]. Did I chose to do this going into the agreement for the loan? Did I get the chance to leave the agreement after the rate was manipulated, or to not pay back interest for the portion of time it was manipulated?

Personally, my loans are almost all paid off and any wiping of student loan debt would barely affect me. I can still see how letting the system continue as it is does nothing but funnel money from the public, and students in particular, into the banks pockets. I don't see why we need to protect the banks from any negative results when they have actively subverted the rules

Not worth reading. For example, this makes no sense:

"(2) decision science, which is about “taking data and using it to help a company make a decision”; and (3) machine learning, which is about “how can we take data science models and put them continuously into production."

Machine learning isn't about putting models into production. It's about machine learning models directly from data.

And if decision science is 'taking data and using it to help a company make a decision', then pretty much any job involves data science, e.g. the guy comparing quotes for paperclips and picking a vendor.

Senator John McCain dies at 81
I mean a few things. For the most part I'm being a bit fatalist: we are all going to die and we are all going to end up in the same place. So the journey through our lives should be one where we embrace other people's differences instead of rail against them.

McCain, to me, seemed to embody values that showed a willingness to work with people who shared different views. He put his nation before himself. That's partly what I was alluding to..
Well, I did a minor switch from Azerty (iso) to Qwerty (ansi) and it took maybe a week or two.

Edit: I get about 140wpm with qwerty and similar with azerty, but switching between them takes some time to get up to speed. Maybe because they are so similar.. :)
>It vastly improves on and simplifies anything that existed in this domain before.

I've read the specs and justification posts. I don't find it gives anything better (and in some ways it's worse) than what can be achieved with, e.g. cargo.

>It's like saying Copernican heliocentrism didn't bring anything extraordinary to the table compared to Ptolemaic geocentrism

Yeah, it's like saying that, with the only difference that we're actually talking about something that brought nothing extraordinary here (as opposed in the contrived example).
> McCain experienced episodes of torture and refused an out-of-sequence early repatriation offer

I'm not sure I can imagine how difficult that would be in practice, though it's nice to think you could do it in theory.

For charge product

q1q2 > 0 : even integer spin attractive

q1q2 > 0 : odd integer spin repulsive

Jumping up classically, for a vector field like charges repel. For a (symmetric) rank-2 tensor field like charges attract.

The weak equivalence principle only requires m_i = m_g up to the sign of the latter. It's the energy conditions which constrain that, notably the WEC component of the positive energy theorem.
I notice that for 99% of the places we go, if we just hike 10 minutes from the ‘touristic entrypoint’, places are deserted unless you can get there by car. Even in extremely densely packed places like Hong Kong or tourist places where in the weekend many people go walking; if you just go a bit further, there is no one for hours. You do not need to go mountaineering for that. A lot of people like nature but abhor walking, so in places like in Spain where I go often you see hundreds of tourists on the picnic place deep in the forest on the mountain you can drive to, but, again, 10 minutes walk on a solid nice path which is forbidden for cars, you will find no people at all. Even or maybe especially in high season (walking in heat seems even worse for people; I love it).
