The "arraypocalypse" name is somewhat tongue in cheek, referring to the fact that this change will include some breaking changes. To provide some very brief motivation for the two most significant changes that are planned:

1. Array slices will create views rather than copies. This is just a matter of performance – although possible, it is currently way too annoying to write copy-free array code. This change will make it the default.

2. Slicing will behave more like APL: the rank of a slice of an array will be the sum of the ranks of the slices. This is a regular and powerful scheme, but sometimes at odds with how slicing works in Matlab.

These changes will make the language easier to write high-performance, general code, while, with some care not making linear algebra harder.

Ask HN: Difficulty taking charge as PM
I am the PM on the client side of a major project that is using an implementation partner who is doing much of the analysis, design and config. They also have their PM who acts as lead PM. On our side, the business team has been working together for years, is experienced and is working very tightly with the implementation team. I am also new to the business domain. In short, I'm having trouble getting on top of things as PM and feel like I am chasing after the rest of the team. I don't feel like I'm adding enough value. Has anyone been through this?

I've looked at a couple of data build tools and many will do basic jobs very well, and some of them will use even a nice dsl. Where I see many tools struggle is with task parameterization, which I found to be a frequent requirement for these kind of systems.

They are really, really expensive to make compared to silicon, and I want to say they run hotter (but my memory is fuzzy).

Silicon has never really been the most ideal material for transistors, but it has always been so cheap in comparison to be the most cost effective.

There is a circle around Boston (that include Manchester and Nahsua, NH) that is very different than a lot of the rest of New England.

I moved from Boston to Nashua, NH (a 90k+ person city less than 50 minutes from Boston) and was right at home; yet there are rural parts of New Hampshire I would feel entirely out of place like it is a different country. But at the same time, I feel there is a sense of unity in most of New England. A shared heritage and creativeness ("Yankee Ingenuity") that binds the region together.

Sometimes I think about moving to the West Coast (usually around the fourth foot of snow in the Winter) but I do like it here.

One reason might be a development environment preference since developing directly in Jython would typically imply the overhead of the JVM. Another possible use case may be porting where a transpiler could address differences between implementations automatically that would otherwise have to be addressed more manually at the source code level.

To put it another way, Jython makes obvious sense when the primary target is the JVM and there's little legacy code. As target platforms proliferate and the code base becomes cruftier, it may become a less obvious choice.

I'm not sure the Pythonic "only one way" extends quite so far as to make Jython worthy of monopoly status.

You can calculate what the non-linearities do to gravitational waves and, in short, this isn't correct.

First, some definitions:

Equality of opportunity: everyone takes the same test, outcome is dependent on individual, even if the group containning that individual scores differently than other groups

Equality of outcomes: everyone takes the same test, but the individuals scores are weighted based on the group of which they are a member, so that representation of groups is equivalent across all groups.

Further, we can separate bias in terms of intentional and unintentional, where the former indicates direct manipulation of selection criteria in order to change group outcomes to match the manipulator's desires. The latter occurs when systematic bias affects the individual's scores, such as when a particular group has less access to educational opportunities.

The article values equality of outcomes, by encouraging algorithms to take into account the individual's group when performing selection. But in cases of unintentional bias, this can mask problems. In the long term, it would be more beneficial to ensure groups have equal access to education than to upwardly adjust their scores.

In fact, this upward bias to adjust for perceived unintentional lowered outcomes can in fact perpetuate the initial biases: the message is that a particular group underperforms, and thus needs extra help.

Point taken; you are right to defend the drug comparison, so long as we're talking about compulsive behavior with negative effects.

I do feel the analogy is overused though, mostly because the notion that chemical reactions in the brain are involved seems to have an unduly strong impression on people, whereas I imagine that these phenomena in the brain turn up in all sorts of human activity (see sandworm101's comment).

There's also a negative connotation that exists with drug usage. I could be totally addicted to jogging, though ("runner's high"), with an almost totally net positive effect on my life.
That's a great question. I do not know for certain, but I suspect the answer lies in reliability and much longer intervals between servicing and overhauls.

Piston aircraft engines have a recommended time between overhaul of 1200-2000 hours (with outliers above and below).

Jet aircraft engines have a recommended time between overhaul of several times that, with required inspections typically at slightly longer intervals than piston engine overhauls. (In a fixed install turbine plant, you might be able to skip the inspections as well, and just use trend monitoring data to determine when to take the turbine out of service for maintenance/overhaul. In an aircraft carrying people, the risk profile is a little different.)
It looks like vaporware to me. What gives me pause is the sneaky way they present it as if it were a KickStarter project, but it's not. So all those people shelling out for the early release are not protected if they close up shop and disappear it seems to me. So many glowing promises, but will they be able to follow through on all of them? I dunno. I am skeptical. (I hope they do though, I seriously want this to be real).
Well, I'm not touching or smelling everyone I talk to. I mean of course, text is much narrower band, but it's not that most of the communication you do day-to-day needs, or even benefits, from the full spectrum of bodily expressions.

Please consider, that current technology gives us the ability to have many, many more conversations every day than our great grandparents could ever dream of. For instance, this whole discussion between all of us here wouldn't happen without Internet. I prefer having "subpar" communication with people all around the world to not having it at all.

Also consider this - we've been having video chat capabilities for a decade or so already, and yet people don't go for it all that often. Why it's so? Maybe because for most of our conversations, not having to involve the messy things like body language and posture and cleaning yourself up from whatever you ate for breakfast are actually beneficial?

Perhaps you meant "better than the US and France"? France has a much bigger nuclear power industry than Russia.

Once we do colonize the solar system I'm sure invidual moons of giant planets will play a larger role than the actual planets. So I don't see this working in the future.

The only future we can truly expect, aside from total annihilation and reset of the planet, would be a total colonization of the solar system.
Show HN: Fictionhub, a place to share fiction
For some reason they've split Metro Atlanta in two, which makes absolutely no sense. I move half a mile down the road, I'm in Greater Appalachia instead of the Deep South.

People in Metro Atlanta don't identify with Appalachia more than they do with "The South", and the northern half of Metro Atlanta definitely didn't side with the Union in the Civil War (which is what the blurb about Greater Appalachia says).

Obviously non-geographic borders are going to be a bit arbitrary, but splitting a major population center like this is particularly bad.

That one is a lot more interesting, though it's basically just a map, which is atypical for flags.

The OP's flag is very abstract. Presumably, any other alien race also strives for unity and lives.

It's hard to create a better flag without actually knowing aliens and having some idea of commonalities and differences with humanity. Indeed, maybe we need a flag for humanity, not planet earth?

No, but newspapers also served as a clear sign of "I don't want to engage in casual conversation". Really, it's not like before smartphones people were actually talking with each other on the bus. Hell, in the fine era of 1990s, when people stopped reading so many newspapers but didn't have smartphones yet, no one talked with random people either - it's sort of a cultural norm in the west.
Yeah, the Futurama one is just fine if you subscribe to American Exceptionalism. Which would suit 4.48% of the world population just fine.
A more realistic option would be to institute a strong audit process. Anytime personal data is viewed or matched against some criteria, it would be logged. By default, those logs would be available after something like a few years, unless there's an ongoing investigation (and that extension would be logged along with who/why it was authorized).

The only way something like this could even work is if there was a completely separate government agency that was both empowered and motivated to be the counterweight against warrantless surveillance. Unfortunately, I have no idea how this could ever happen.

Two things:

1) Blue and white aren't exactly politically neutral. They tried to give Iraq a blue and white flag, with blue stripes representing the rivers. It did not go well.

2) A flag should not be so complex that children cannot draw it with crayons. The interlocking rings are nice, but the specificity of which goes under which makes things too difficult. The union jack is perfect example of this complexity but at least there is was the result of various mergers.
It's an interesting start, but the balance feels a bit off. A bit too yonic in the center and the way the rings overlap with negative space makes it look worse at small sizes. Realistically speaking a flag is in many ways the way you are different from other flags but this raises the question: Who is looking at the flag of Earth? Who does the flag not represent? In the short term I'd argue it's Venusians or Lunarian settlers. To them a flag that represents origins is more important. I like the idea of a blue background symbolizing water / the earth sky, and the primary molecule that makes up our actual tissue, but the symbol in the middle shouldn't be based on circles. All planetary life would want to use a circle. Especially as the flag for the first planet that humans arise from, it's weak.

In the long term the symbol for Earthlings may even be observed by aliens. In what ways will we be different from them? The flag may even be used as a symbol for other Earth species like Dolphins once we get the technology to communicate with them effectively or to artificially increase their intelligence.
> The Vereenigde Oostindische Compagnie (VOC), or Dutch East India Company, is often considered the be the world's first multinational corporation. ...

Ah, trivia time! The VOC also had the world's first entirely privatized army. The "monopoly" cited in the README basically included a license to kill. Think "Google Armed Forces", but then scarier. The army was mostly used to keep a grumpy unpaid workforce "motivated", to keep the spice coming, and thus to keep that lovely 18% annual dividend payout reality.

Basically, the VOC made current evil multinational corps (e.g. the oil companies, monsanto, blackwater, etc) look like cute cuddly charities.

That said, it's been centuries, not sure getting worked up about the name makes sense now. It's a compiler, not a guidebook about how to traffic humans. I just thought the README section made the VOC seem a "little" awesomer than they were.
Yep. I used to be involved in a community of "crafters" (not accurate, but close enough). There are fairs all over the country, where said crafters set up the booths in small to medium convention center settings, and sell their wares. You pay a fee to the organiser, set up, sell, tear down Sunday night and go home.

Most crafters came and went. A few consistently made money, and they usually had permanent businesses; the fairs were a way to connect with the community and spread awareness. The big money was made by the organiser: "the store."

You may get rich mining for gold, or you may die. Selling pick axes to miners is a pretty good business, and there's always new, hopeful customers.

"It isn’t that residents of one or another nation all think the same, but rather that they are all embedded within a cultural framework of deep-seated preferences and attitudes—each of which a person may like or hate, but has to deal with nonetheless."

You're right, but people still argue for nuclear. It's silly really, and will be somewhat humorous to watch new nuclear plants come online in 10-15 years that are immediately unprofitable because wind and solar (backed by battery) are already cheaper.
Seems like using a flag that gives an unknown contact your home address is a bad idea. That information might not be something we want to communicate right off the bat.

I actually meant Russia, typically France's nuclear research and the US research is, as far as I can tell pretty much joined at the hip. That also goes for English, and German research as well.

Both China and Russia began nuclear research programs against the interests of that western block, and because of that history, sharing was (and as I understand it from folks I've talked to about collaborating, still is) not freely, or as freely, shared. [would love to hear from current researchers though to know if this would agree with that impression]

Thus independently seeded programs tend to have different approaches and limitations, and that gives them the opportunity to progress differently.

From that perspective I see France and the US as the same body of research. (although I agree, the French have an extensive program).
