Well intuitively an n-dimensional generalization of matrices would just be a big multi-dimensional table. But a tensor is different in that you have some number of dimensions which are covariant and some number which are contravariant.

Additionally, you've sort of got it backwards. A matrix with units (and a set of basis vectors) attached is one representation of a rank (1, 1) tensor. But it's not really a unique representation of the tensor - you could choose a different set of basis vectors and come up with a different matrix representation of the exact same tensor. The tensor is an entity, while the matrix is a representation of an entity within a given coordinate system.
Honestly, I agree with Nadella here. They built a technology which happens to be useful to the military (and has many, more numerous, non-military applications), and the military (understandably) wanted to use it.

Protesting selling Hololens to the military here is like protesting contributing to Linux because the US DoD uses it. Should we all boycott Linux because of the lack of an anti-military-use clause in the GPL?
Yes sorry I should have also mentioned that it only really saves time if you have ddg as your default searchbar engine!
Walmart Is Eliminating Greeters. Workers With Disabilities Feel Targeted
That's sort of the whole point, though. Long-time Portlanders are frustrated at getting priced out of the rentals they live in, as rents increase faster then their salaries increase because of newcomers competing for the same supply.
I have lived in Japan for the past 6 years and smartphone addiction is high. Mostly eldery people are the only ones reading newspapers or books. I've seen them just looking at nothing (falling asleep while playing some stupid game). The number of times I have come close to bumping into people is insane. My best preventative is to make loud claps and it snaps them out of the phone.

I think most people are stuck to the smartphone because everything (2FA, calendars, messages, phone calls) centers around your phone. I have missed my fair share of calls from the wife and others because I never check the thing regliously. I think it is how much you interact with people that kind of determines how much you will use the smartphone for communication vs entertainment.
"Files transferred over Shell protocol (FISH) is a network protocol that uses Secure Shell (SSH) or Remote Shell (RSH) to transfer files between computers and manage remote files."

"The protocol was designed by Pavel Machek in 1998 for the Midnight Commander software tool."

I'm not saying that there's no very big model, just saying that it's a minority of publications, for any trivia example of big model I can show you 10x trivia examples of relevant non-big models.

Also you are talking about a model which is specifically designed for TPU (the dimensionality of the networks is especially fine-tuned).

And even tho, BERT_large still fit in the memory of a single GPU (for very small batch), there is an implementation on Pytorch. I don't understand, are people complaining that Deep Learning is actually (reasonably) scaling ? Isn't it a good news ?

I'm not sure we can turn the clock back like that. Back in the early 80's computers were expected to do very little, so we were easily impressed if they did anything. For those of us who were easily impressed with this, it got us interested. And it was possible to bang out a somewhat-playable version of an arcade game in 12Kb ;)

Nowadays the expectations are so much bigger. I've seen people create their first website and be disappointed it looks so crappy, rather than excited it works at all. Not everyone, mind - some are still excited.

Reminds me of Yellocabs in NYC. The screen can be muted but you're still staring at a lit blue screen while riding in the back of a cab and it's very unpleasant at night. Try relaxing if you can.

It took a long time for agriculture to spread. Crops that work in a Mediterranean climate do not work in Northern Europe. You have to breed new varieties. That can take hundreds to thousands of years. Heck, it’s still hard to grow certain kinds of fruit up here in the rainy parts of Oregon and we know how genetics and inheritance work.

I don't see how any of this relates to direct sabotage of US military. Again, requesting that your bosses not make a specific sales is not an act of sabotage nor is it in any way aide to Russia or China.

The United States must set positive examples for the world. A country that effectively forces corporations and their employees for the military is fascist. The public pressure for Microsoft to work with the military is disconcerting. Opposing people like the OP make it sound like anyone who holds a differing opinion is mentally ill or something.

This isn't an okay state of affairs.
The Greeter at my local Walmart has a nasty scowl and makes me feel really uncomfortable every time I walk in there. I for one welcome this move towards a more anti-social world.
I'm not actually taking a stand on 'women in combat' one way or another at all.

I'm saying that for 90% of roles 'gender doesn't matter' really. So it's 90% a 'moot point'.

Without taking a stand on the issue ... I believe that in reality if there were a relatively major conflict today, women would be getting close to the lines but not on front line units for the most part. Pretty much every other role they would do.

Wayfarer's Dole
Jack Dorsey just discussed this concept a bit in an interview on Bill Simmons' podcast. They were discussing the pitfalls of giving users (or others) the ability to edit/delete their tweets.

In discussing having a N-second window where a user can correct typos, Dorsey brought it down to a tradeoff between real-timeness and correctibility. Essentially he feels that much of Twitter's charm as a platform comes from the fact that updates feel "live", so every delay from tweet source to delivery needs to be given a heavy cost in the cost/benefit analysis.

Adding a delay like that as a feature (especially for a figure notable enough to move the stock market with a tweet) would undermine that message completely, by preventing that figure from engaging with the conversation in real time.
Ask HN: Unfairly Flagged Submissions?
There was an interesting story from the Guardian submitted today (not by me), "The deadly truth about a world built for men – from stab vests to car crashes".. Which was fascinating, well-written, well-researched, about how a lot of things in the world are designed to fit men's bodies, and can cause problems (or death) when women try to use them. It first attracted 1 horrible comment, then after 3 more comments it was [dead][flagged]. I didn't see anything in the article that would at all warrant flagging, so I tried submitting it myself, but just ended up on the comment page of the previous attempt. The topic seems one very relevant to people in computer-related fields of all kinds, and one I don't remember reading about before, so I don't think it's been done to death on here.

So I was wondering... 1. Does this often happen on here, stories on particular topics flagged to seemingly censor them, prevent them being discussed (which is a matter of opinion, I guess, which ones fit that description and which don't). Are there notable examples of this from the past?

And 2. What should I do here? I don't know if it was a couple of people effectively vetoing the article, or some kind of consensus. I was very surprised to see this story flagged, and would have liked to see it discussed.
How to Create the Future
I agree. I think it may be naivety. There even was a thread here on HN about how saying that the world is fallen is just religious and therefore should be avoided [1]

These people might think human beings are fundamentally good and war is just evil people doing evil things to each other.

But evil is just a reality. People band together to kill others to get what they want unless you kill them or raise a credible threat to kill them in return. This is what war ultimately is.

If men were angels, no government would be necessary

Salary is never reasonable. Employment is essentially slavery which is never reasonable, at least with the surplus we have at this age.
I can't recall someone ever saying "welcome to walmart" to me, anywhere in the US. Even so, I don't think someone saying that to me would be enough to humanize the face of one of the world's biggest megacorps. Maybe if they handed out coupons or free food I would be interested. I sympathize with these workers but I don't see myself going into the streets to protest this.
Little do the protesters know that the actual tools of war are PowerPoint and Word.

No mission is launched without first planning and revising using those tools.
This look really interesting. I am really happy to see something with great benefit to society in YC. I would suggest looking at Future Agenda [1]. I have worked with them in the university setting and both OWID and FA seem to be in line.

In a recent interview on CNBC, Buffett said that Walmart CEO
Doug McMillon always carries with him a list of top 10 retailers of each of the past decades just to remind himself of the brutal history of retailing. Walmart took Sears to the cleaners and with status quo, there was a high chance Amazon and Costco will take Walmart to the cleaners. So far, they have done a pretty good job modernizing.
In Boston it's still possible to buy lobster literally out of the back of a truck.

Lobster was so plentiful off the coast of New England that it was historically a common man's food -- marketing elevated its status significantly.

This is impressive, but it adds yet another very complex io api to the Linux list.

Compared to this Windows is looking more and more impressive and their api is decades old.

I’m sure this is higher performing in some benchmark setup, but very little cpu time is spent on kernel overhead for any heavy io application.

It would be nicer just to have a clean set of flexible asynchronous apis that all shared a relatively simpler model.
Is the contract simply "selling Hololens to the military"? My understanding was that they already had contracts in place to sell them to the military for training purposes and have done so for many years. I was under the impression from other articles that the employees are upset over the request for "targeting ... capabilities" to be embedded into the devices.

Edit: Upon reading their 'letter' it appears they take most issue with the use of Hololens to 'increase lethality'. I would argue that even the use of Hololens for training purposes (as they have done so in the past) would increase lethality anyway (as training of any kind might) and they apparently had no issue with it before. Even then, the military doesn't need Microsoft to do it, they could pay any of their contractors to implement it.
Great news! (Oregonian here) We were kinda pushed into buying our first home because our rent went up $100/month in 2017 and then $200/month in 2018.. I saw where that was headed and we made home buying happen way sooner than we wanted too.

Glad to see this is being addressed because some just can't make that happen.
One has to ponder philosophically whether that "bug" is actually a bug or not, given the extremely pathological situation it involves:

This bug can manifest itself for arrays whose length (in elements) is 2^30 or greater (roughly a billion elements). This was inconceivable back in the '80s, when Programming Pearls was written, but it is common these days at Google and other places.

If you're using a 32-bit system, which has only 2^32 bytes in its address space, of which half is typically taken up by the OS kernel, leaving 2^31 bytes for your process, you can see just how strange this is; you would only be able to have an element size of 1 byte, for 2 would fill up the whole 2^31 bytes of address space and leave no room at all for code, and the memory manager would need to let you allocate a whole 1GB block --- and that's not even considering why you would ever want to binary search an array that large at once.

Of course, to use a 32-bit element count on a 64-bit system is itself a more valid bug, but otherwise the "bug" would appear at 2^63 elements --- clearly well beyond the capacities of computers today (x86-64 has only 48 bits virtual address space), or for that matter the size of anything which would be practically binary searchable.

Thus IMHO this is really more of a curiosity along the lines of "you'll run out of memory if you try to ask for too much", and you're probably doing something either exotic or just plain wrong if you need to fill up the machine's address space with a single data structure.

I forget how this was accounted for in Kim Stanley Robin's famous Mars trilogy (highly recommend; best Sci-Fi book I've ever read). I think Earth and Mars were so far apart with time delays and everything else that Martian days/years took on a meaning of their own.

I remember going to a mall once and being in an altered state of mind... [Mainstream] music felt like something used to get people in an almost hypnotic state of ignorance, an acoustic bubble to encourage shopping, mingling... I don't know how to quite put a finger on it. It wasn't anything particularly negative, but it was the thought of it being some sort of mood manipulator, setting a scene for those who were well off enough to be a part of it.
I stayed at the W hotel in Chicago on a business trip once years ago. The music sampler they provided was like listening to some mix made from my wife's playlist. So yeah, I don't plan to take her to the W, or that will be the only place suitable for the rest of my life. It's pricey and they have expensive stores all around it.
crypto/tls is designed and developed to be fit to be exposed directly to the Internet. The advice I wrote here is mostly dated (I really need to write a follow-up), but it's still indicative: https://blog.gopheracademy.com/advent-2016/exposing-go-on-th...

[Updated to add] TLS 1.3 is opt-in because despite years of improvements, it can still hit compatibility issues with broken or legacy peers. (Search for "TLS 1.3" on the Go issue tracker if you are curious.)

0-RTT is blocked on figuring out good, safe APIs for it. I feel like I am 80% of the way there for servers (just have to figure out how to make it opt-in per http.Handler instead of opt-out), while for clients I have no idea how to fit resending in io.Writer.
It's not direct, it's indirect sabotage. As said in OP, tech giants from China and Russia don't have employees protesting military aid just because 'the technology is scary and can do harm'. I also highly doubt the US 'setting an example' will change any of their minds.

If none of the United States tech giants sign with the Government, it's very likely that the US's technology used for an upcoming world war will be inferior to that of the US's enemies.
The earthquake didn't cause any damage. The single point of failure was the seawall being breached. The rest was a zipper of each failure causing the next. The tragedy is this zipper could have been halted at many places.

For example, the hydgrogen overpressure in the reactor (caused by previous failures) was vented through an overpressure valve into a pipe. The pipe exited into the enclosed reactor building, which lead to an explosion.

The pipe should have been vented to the exterior. The cost of that would have been insignificant, like numerous other zipper-stops.

Deepwater Horizon was a big zipper, too, none of which would have been costly to prevent.
That title immediately makes me think this is a hit piece.

It looks designed to place Walmart in the worst possible light.
According to interviews with workers and documents reviewed by NPR, to qualify for these new host positions, workers must be able to lift 25 pounds, clean up spills, collect carts and stand for long periods of time, among other things — tasks that can be impossible for people with disabilities.

1) Who employed at my local Wal-Mart does this now?

2) Why do these job duties need a new title?

I see a lot of comments referring to a study that says it does more harm than good and I haven't read into them yet but my first question is: Does it measure the impact it has on community? As in does it take into account the fact that a community needs residents to stick around, not just live in boxes and not interact with each other. Because my experience with a $100 then $200/month rent increase showed me that it is going to destroy the community of long time renters in the neighborhood. Hopefully it addresses that.

How about an API?
The small parts of the Mars Rovers (MER) I worked on or worked with didn’t use SQLite. It was too early in SQLite’s history for it to be used on MER. MER also used VxWorks which probably didn’t have a lot in the way of POSIX support at the time. I remember other devs telling me the fun they had supporting 1553 bus on “such a new RTOS”.

Wikipedia say MSL used VxWorks as well.

I’d have to ask a buddy still doing Mission Ops Support at JPL but I’d think the answer is no SQLite on MER or MSL missions. The OSes were fairly custom, non-POSIX builds. The ESA folks might have tried though on their missions.
While I suspected this happened in the USSR, I had no information. Thanks for it!

There are newer PPCs as well, like the Talon motherboards.
I'm not super familiar with the specifics and I'm sure someone who's worked on this particular probably will be able to clarify, but the way I understand it there is a limit on how many characters can be displayed on the screen at any given time, as well as a minimum amount of time a subtitle should be visible on the screen. Because of this, transcribers might be forced to write down a shorter version of the line in order to make it fit.
