There's a company that makes kite sails for cargo ships, which have proven effective [1]. However, as the fuel costs are payed by the shipper, there is a lack of economic incentive for ship owners to purchase them.

Thanks!

I started my kid with Scratch. Then had him do some of the Hour of Code challenges on Code.org and then some of their courses (recommended). Did a couple Arduino projects programmed with ArduBlock. Now we are working with a VEXIQ kit from Vex Robotics and working our way through the RobotC course. All graphical programming so far. Want to start looking under the hood at the actual code soon.
Age? How many young kids are curious about how plumbing works or lawnmower engines? It probably has more to do with you and your friends being curious about something and not understanding why other people in general aren't curious about it.
Stop-start cars are amazing when the battery/alternator starts getting a little dicky after a few years. Pull up to the lights, engine shuts down, and doesn't start back up. Genius.
It is only data from universities, not real for-profit businesses.
Encryption while keeping the "shape"/"form" of the data intact. This way you can have secure third-party computation, without that third-party knowing exactly what data it is operating on.
Tests Georg is an outlier, and should not have been counted.
You encrypt some data and send it to Bob.

Bob does some computations on the encrypted data and sends you the (still-encrypted) results.

You decrypt the results to get the answer of your computation. Bob never learns what your data is or what the results are.

The term "homomorphic" roughly refers to the fact that the encrypt/decrypt functions go "outside" the computation. That is, if Bob is applying the function f, we have f(Encrypt(data)) = Encrypt(f(data)). The left side is what Bob does, the right side is what you want to get (because you can decrypt it).

EDIT. To see how cool this is, think about this: I have two numbers, I encrypt them to form long strings of gibberish. Then I have Bob perform the "multiplication" function on the gibberish and send me the result, and I am able to decrypt that to get the result of multiplying the original two numbers. If that doesn't impress you, I send Bob my database of encrypted emails, then ask him to do a string lookup for "chocolate", he sends me back the set of matching emails without ever knowing what they say or what string I looked for.
You also need to prevent the resulting trees from burning or rotting, to keep the carbon they captured intact.

It was "easy" when tree trunks kept falling into ancient swamps for millennia. Right now it's not as feasible.
This may appear to "work" but I doubt it is better than a 300K FPS camera by any means. It will not work perfectly across all scenes, it cannot interpolate uncommon movements and finally, it cannot interpolate many low-res cases like 5-20 FPS where there is actually significant missing information across frames.
Indeed, I remember when PhoneNet made ad-hoc AppleTalk networks a bit easier (although, by then, the LocalTalk hardware, genuine and clone, was common enough, too, except sometimes long enough cables could still be a rarity).
Agreed. I don't see how justice and bargains are compatible.
> none of those things matter

... unless the software's needs evolve over time such as to require them.

> you know if your gray box ships with a 10gbe card or not

Yes; and lucky we do know. Else, our upcoming model of gray boxes that - unlike their predecessors - aren't approaching EOL but are only available with 10gbe cards ... would already be shipping with broken networking.
When you say "data science" does that encompass traditionally educated statisticians and business intelligence folks? If you only count the practitioners out there who self-identify as data scientists you get a pretty incomplete sample of what the field actually is.
I mean... there are many years (since being an adult) that I haven't read a book: why would I need to read one when I have online news, blog articles, wikipedia and other such resources.
The idea of my approach was that a "power user" could add the rules and scores without having to understand something that may take a while to explain. A scoring sheet can be displayed for a given message that would make sense to just about anybody with an associate degree. Example scoring sheet for a given message:

Category: Spam
Rule-ID Score
----------------
NgrPrnc1 7
bPills 5
knownPeople -3
Total: 9 Threshold Exceeded!

Category: Tech Support
knownWidgets 3
offer1 -2
Total: 1 Insufficient total

Category: Etc...

One could click on the rule-ID as a hyperlink to see specifics of a given rule (if details don't fit on screen).

What about refrigerated diesel trucks? When the diesel engine turns off, the cooling turns off. Has this tattletale also considered the horrendous emissions of engines whose catalysts cool down? Idling is sometimes cleaner, sometimes dirtier, this kind of blanket enforcement makes no sense to me.

Where I live in CA, people object to diesel idling more due to noise than anything else.
"If you accept a trial's outcome that the accused is guilty, it follows logically that they deserve to be punished more for denying it (or at least, more than they would be punished if they confessed.) "

Except we know lots of innocent people have been convicted and later (often MUCH later) exonerated.

The fallibility of the court system is a strong argument not to load up penalties because someone simply exercised their Constitutional right to a trial.
For many people who started worked before the 80’s, using a keyboard is for clerical work, and a sign of reduced social status.

Any estimation on the co2 output building said walls and surrounding Greenland and Antarctic with them. What about animals the navigate through these waters. This just doesn't seem like a well thought idea to me.
Ok please.

Modern cars, to a greater or lesser extent, aren't too bad with running on fresh startup due to modern oil technologies.

BUT. This is not a universal case.
Large diesels like to idle up before operating. Performance cars (especially turbocharged cars) will live longer if you allow the fluids to warm up correctly. My race car will absolutely shit the bed if you don't warm it up before operating.

And to be fair, as far as mechanical sympathy goes, it always pays to warm up your car. It'll be the difference between the car going 100,000miles or 150,000 miles in a lot of cases.
How do I get my account banned? I’ve been trying to delete it but can’t figure out how.
Two notes:

1) I am evaluated on the progress of my students. While bad ones will actually be fired, good ones are more useful to me if they go off and get postdocs etc. Some of the most powerful "businesses" in the field are created by the network of people who all trained with the same PI and then went on to found their own labs.

2) A burnt out, trapped graduate student is not actually one that produces good work, in my experience.

3) Several grants, which are how I fund my lab, will look very poorly on trainees making no progress. There's very little exploitation that's worth a program officer at the NSF wondering if I'm worth there time.

Are there bad, exploitative PIs? Absolutely. But these people are assholes, not the only logical outcome of the system.
Tell us your thoughts on voting.
Indeed. By way of comparison, my department has zero TA lines.
It seems obvious in retrospect, but persistent memory adds a pretty exciting new advantage for persistent data structures.

Another thought: As potentially paradigm changing technology like this becomes available will it ever make sense to redesign the OS?

A homomorphism between two sets preserves relations between elements.

A set with a single operation (plus some extra properties) is called a group. The integers with addition (+) is an example of a group.

Suppose I have groups X and Y. Then a group homomorphism, h, is a mapping at that preserves the + in the two groups, so

h(x +_X y)=h(x) +_Y h(y)

Where +_X is addition in X and +_Y is addition in Y.

Homomorphic encryption means that what you used to do you encryption is a homomorphism.
My claim is that some of these optimizations on BFS/DFS style questions were never something most people could effortlessly solve in a few seconds. Which is how I took the claim of the OP.

Incorrect. My point is that some high GPA undergrads don't seem to have the habit/ability to even think along those lines. Of course we aren't going to ask for a difficult and polished algorithm in an interview. We throw simple stuff at them, to see if they know how to approach a problem. There are some common problems which are trivially solvable by imply throwing BFS/DFS at them. These 3.75+ GPA wunderkinds will flub those! At least one HN commenter replied to one by saying they could solve it in a couple of days.

Not to mention, most solutions people give in seconds are at best a good starting position.

Too many of these supposed A students can't even get to that starting position.

I've literally seen folks that think someone should be able to write algorithms such as Knuth-Morris-Pratt in a standup interview.

No. What we ask is more along the lines of: Would this candidate be able to think through what would happen if they used DFS on this graph? And that is just about the hardest thing we'd ask.
This is a great piece. I think my only addition to it is to point out two small insights.

1. SemVer works great in some communities (Ruby) and shit in others (Python). Generally the more computer sciency the community the better I find the SemVer'ing. Python has a bunch of scientists using it, so it's less reliable, even if many of the core libraries follow it pretty well.

2. Apps, plugins, frameworks, and libraries are different things with different SemVer strategies. With a paid app versioning is often a marketing decision. Framework plugins versioning is often a "match the framework to reduce mental burden" decision. Whereas frameworks and libraries I find a much higher adherence to what SemVer strives to do.
Yea--I'm not blaming doctors, nor drug companies.

Americans are misserable on so many levels. I believe most people who really liked opiates, are also very depressed.

Life in America, since the 80'-90's has been not great for many of us.

I'm not suprised people liked a drug that lifted the depression, and completely took away the anxiety.
I actually switched to this a couple months ago, mainly because I was using other habit-tracking apps that only allows a certain number of habits available for free.

I didn't even know about the statistics, as I just wanted a way to check yes or no and see the past week to see if I needed to change things from week to week. Knowing I can see the trends changes everything... I think I'm going to need to add a few more things to this because this could be extremely helpful for me with several things. It was helpful enough just seeing week to week at a glance, but being able to see trends and long-term progress is great.
The difference is that your pistons, rings, bearings, etc have not come up to operating temperature and have not expanded due to heat. It's not going to explode immediately but you are reducing the overall lifespan of the moving parts if you drive on a cold engine.

Most modern cars are a lot more tolerant thanks to advancements in oil technology. But it is to a greater or lesser extent better to warm your car up, even if it's not immediately / apparently necessary to you.
> Still plenty of stuff to complain about, but the job market looks far different than in the natural sciences or humanities.

Yup. Economics [0] and comp sci are basically the only doctoral programs worth going into at this point (at least if you're an American citizen). You can debate which one is _more_ worth it, but the fact is that if you're doing anything else, you're in a for a world of pain.

Irrelevant. We're concerned here about the edge cases.

Yes, sure, there's a lot of obviously guilty people that get charged for the obviously illegal and obviously immoral thing they obviously did, and then they get the obvious punishment, fine, great.

> DAs don’t make a career of threatening trials for cases that aren’t locks.

That's not remotely the same thing as "no DAs ever threaten trials for cases that aren't locks". That does happen, all the time, and to the people who get caught up in it, the fact that the DA doing it isn't making a career of it is cold comfort.

It also doesn't consider a wide number of other structural issues involved with prosecutor discretion, or with the systemic imbalances in the system, as discussed in, eg, the linked article.
This is something that can I cannot stress the importance of, yet rarely ever receives the recognition that it should. Being able to delicately and compassionstely work on old code, while still bringing valuable updates is hard.

It’s even harder to make your changes look easy and obvious in hindsight.

This is something that most engineering organizations are not equipped to recognize and promote as a virtue - it’s sort of hard to explain as it is. If anything, this patience can be considered an enemy to progress.

When you see people who do this well, take note.
> Getting rid of the plea system doesn't change that.

What it does do is reduce the sentences for wrongly convicted innocents to ones that are reasonable for the crimes that they supposedly committed.

If a guilty person who pleads guilty gets two years for a particular crime, why should an innocent person wrongly convicted get twenty years for the same supposed crime?

Combat vet reporting in: you have my permission to view the rest of the Snowden documents. While secrecy does have a role in operational security - taken too far it does much more harm than good. I'll never forget the news rolling in about the leak, and how vindicated many security folks (including myself) felt in regard to how insane the surveillance apparatus had become. It was hilarious watching them drip feed the leak, see the predictable government lie, then see the next leak proving that the government just lied.
I try to encourage everyone to define a contract, code to that contract, and update the contract when it is no longer accurate. The exact nature of the contract is contextual, sometimes a schema, sometimes a well documented comment header or perhaps a project README.
About 1,000,000 people legally immigrate to the US each year. That's hardly indicative of a "fucked up" system.

Sure there are 7 billion people in the world outside of the US, but we can't just open our borders and let everyone come in. It would be chaos and destroy the country and all the reasons for coming in the first place.
Can you explain why you think this? I entered a PhD program at the start of the summer and I can't think of a way that veterans would be punished in the application process.
Part of the reason to mention building codes is that building codes in the US enforce car-centric building in many areas, by mandating maximum densities, parking minimums, road setbacks, etc.

And part of the reason for that is that many towns buy an off the shelf municipal code called municode to start from.

Arguably the vast majority of the processing power is in the plasticity. That is what enables learning.
Look - the next 10 years is all about card-circulators. It's actually a combination of two things: Cards, which present business metadata such as contact info and personalized notes, and a circulator, which efficiently organizes and presents the best contact for any particular job. We're branding it Rolodex, but really, there is a whole industry ready to break the mold of traditional B2B.

the users will need to adjust to new ways of organizing and sorting, but some power users already have proven the new model.
I'd assume marketing considerations dominate the version number discussion for (consumer) applications--whether you want the release to be seen as the good old whatever you know and trust or as new and improved.
Not to take away from your point, but I like to imagine

My mother was prescribed it to deal with transient insomnia, and very much used as directed. For two nights she had fine sleep, and on the third day called me mid-day. She was sitting in a chair crying, and said totally calmly that she didn’t feel sad, and had no idea why she was crying. She stopped Ambien immediately and that was that.

I’d stay the fuck away from Ambien, period.
It would be great if they did this in Miami, too.

Does it generalize? Can you in theory perform any computation in this way?

> What about animals the navigate through these waters

This is going to sound mighty unpopular - it already does to me while I try to formulate the right way to say this in my head...

But at what point do we need to conclude that saving the nearly 8-billion human beings and the overall habitability of the Earth is of greater importance than certain animals living in individual biomes?

I know it's not the contemporary, popular thing to think about. But if the alternative is the mass displacement and deaths of humans, it feels like it's something we're going to have to make a decision on.
If you read through the comments of the closed pull requests you will get some idea of the type of enhancements that the maintainers expect.

Nitpick: It's specifically surrounding major glacier outlets, not all of (or even a significant portion of) the landmasses. A complete surround would be effectively impossible.
Why?

If a qualified member (bachelors in physics, within UW Physics' normal acceptance criteria for grades/GRE/etc.) of the armed services stepped up and said to our research group, "I think gravity is the coolest thing in Physics, I'd like to spend the next 5-7 years measuring it, and here's why!", that person would have a big leg up in admissions to our department.

I've worked with a number of current and former military in our group. To a person, they've all been great and know how to get things done. Indeed, one of our research scientists is a former submariner.

Wouldn't it be easier to write optional variables, allowing you to keep the same method name? This results in cleaner code that doesn't break existing usage.

For example:

}
The initial release was really underwhelming, given the hype around this. So my personal (uninformed) expectations is just incremental improvement to the initial product.
