You're confusing a tensor with its representation. Tensors are objects which must obey a certain set of rules. (Which rules depends on whether you're talking to a mathematician or a physicist.)
Not this time, but I've had similar experiences as a result of cute programming language naming conventions
This! I think what I'm going to start doing is to not take any computer professional seriously unless they are an ACM or IEEE member (or similar org in your country).

EDIT: Getting downvoted, clearly not a popular opinion. Are people here not interested in having a strong corporate-independent organization to push the industry forward?
That doesn't seem to be using a flipped classroom model to maximize value of in-person contact time by moving static lecture out of classroom time; that seems to be replacing much of the school-hours direct contact time with online solo learning.
I've always ended up with, and still reach the conclusion that there are only two tenable options which will work against a corrupt and unethical system.

1. Infiltrate, subvert, and implode the system from within (that's meant to be as Tzu-esque as it sounds).

2. Using parallel propaganda to get the public to realize that they have the ability to disable the system if they can collectively wield a moral, objective, and ethical compass (with all the McLuhan-esque difficulties that come with it).

I prefer the former. As dangerous as it is, I think it's strategically easier to wield covert action as a tool for effecting change than it is to attempt a unification of the masses. But, maybe a combination of both these approaches would be ideal.
Something about Calabi–Yau manifolds.
Alright, I’ll take the heat for asking the obvious question:

Who would ever need a folding phone? This sounds like a silly idea. Apart from the obvious party trick (“hold my drink - ima fold this phone in half”) I don’t see any reason for a phone to fold halfway down the middle into a ridiculously thick package that can’t be comfortable carried inside any reasonably sized pants pocket.
Most places have built way more infrastructure than they can afford to maintain. This isn't an MA only problem. This is a nationwide problem.

Likely if you looked at your state/city/county budgets, they are spending more on road construction and maintenance than they are receiving in vehicle related taxes and fees.
Yes. It's like Notepad. It's small, lightweight, loads instantly, needs no manual, is available on every machine, and perfect for simple editing tasks.
I'm confused as to the implication of your comment. Is it peak or rock-bottom internet to get to what appears to be some form of antisemitism in the first comment?
If the state hasn't shown that an accused has committed a crime before the state trespassed but needs to trespass first to then dig up an ex-post justification for trespassing witch hunts develop.
This isn't all that uncommon in C. It's not really fundamentally different than pointers to pointers, just a slightly different syntax:

int a = 1; int *b = &a; *b = 2;

If this can be compiled to efficient assembly, I don't think that kind of variable binding presents much more of a challenge.
I share your wish and think that people are coming around to the idea of respecting places digitally.

I've noticed that Big Agnes, for example, is pretty discrete about the locations in their catalog. Last year there was a picture of a hot springs in an Idaho wilderness area and the caption was simply "secluded hot springs".

As one of the people who started the 8th LNT "movement" (really just a haphazard attempt by myself and two friends to create a coherent "policy" stance to bring the multitude of conversations about social media impacts together under one banner) I appreciate you bringing that idea up and linking to the articles you did.

LNT likely will never add an 8th principle (and in hindsight I wished we'd called the "movement" something else), but they were very responsive the idea and acknowledged the problems -- hence the social media guidelines they released. I think the fact that they did that was really courageous of them, given the potential for backlash by the "don't tell me what to do online" crowd.

I'm also very emotionally invested in public lands (I moved cross-country to be closer to some of the wildest places in the lower 48 five years ago) and think that most people who are see the fact that social media impacts wild places, often negatively.

Bummer about your friend's friend, but just goes to show just because people project an "outdoorsy" vibe doesn't mean they really care at all.

Thanks again for linking to the articles you did, makes me happy to see someone else out there "gets it". Hope you have some great hikes this summer.
I'm not arguing that they "act[ed] in bad faith".

I'm arguing that they misused data that they had. And so they actually didn't have enough evidence to file a police report.

But it's also arguable that the police screwed up, by not noticing that the photo from the video didn't match the suspect. So maybe the kid should also sue the police for false arrest.
Wait, what?

runako: If you make $23k, you don't have a job that gives you health insurance.

rayiner: None of this is a big deal, because most Americans have health insurance through their employer.

Er, what? Yeah, most do, I guess ... the part making much more than $23k.
I would LOVE something as simple as the Windows XP version of Paint on Linux. Something that opens instantly, doesn't have a bazillion options, nested and floating tool menus, etc.

I've tried Gimp and a few others and I end up wasting way too much time just trying to figure out how to do basic stuff like draw a red box around something.
And yet conservatives are usually the ones writing off the liberal arts as useless pursuits of "liberal snowflakes", not advocating for them as essential facets of civilization.

Edit: To be clear, the behavior described by the above commenter is reprehensible. Independently of that, I think it's incredibly sad that universities are being turned into businesses that only care about profit. Obviously that makes the original article a mixed bag.
There is a whole alt-right idea of "Demographic shifting" as a tactic being used to suppress their opinion. Unfortunately Americans are really stupid and conspiracy theories have gotten a deep hold on society.
The 2016 Democratic platform included a resolution for constitutional amendment to undo Citizens United in the first 90 days, do you think they were hoping to lose?

I provided a bunch of evidence over two decades of Democrats uniformly supporting election reform, and Republicans uniformly opposing. If what you say is true, it should be trivial to provide examples of the opposite, so why don't you?
FAA Certifies Google Wing Drone Delivery
This shop does not sell only crepes, it sells also other related things, like donuts and waffles, organic juices, and the like.

It works 24/7 with shifts and has delivery that covers the whole city.

To reach that amount, this guy worked his butt off for 3 years non-stop.
I have issue with the trespass part as well. If marking chalk on a car is trespassing then wouldn't throwing a newspaper in someone's driveway also be trespassing? So to would leaving a hand print on someone's car if you happened to touch it.

They aren't illegally entering the car, they're putting chalk on the outside of it.
I don’t know about best, as there are lots of trade offs between various projects. I’ve reviewed and worked with a lot of Java based ones, top of mind:

- Airflow

- jBPM

- Enhydra Shark

- Activiti

- Netflix Conductor

Most of those are more workflow engine than pure orchestration.

A few years back, we searched high and low and I was generally unhappy with the commercial offerings so we wound up building around Netflix Conductor (after a disastrous run with Joget, which is built on Enhydra Shark).

Since then I’ve been pretty happy with Conductor, submitted numerous PRs and accidentally became one of the people keeping the MySQL backend implementation going forward.
You could probably look at your state budget and find out, if you are really interested.
> The regulation won't necessarily help anything but to outlaw a lot of smart people from being able to write certain software. It will put us further behind the USA in our ability to create tech companies that matter (or that can compete with offshoring)

Has any of that happened with engineers in Canada? We still have plenty of engineers.

A lot of this comes off as any industry wanting to hold onto the engineer title without any of the accountability that should come along with it, or really any accountability at all.

I don't want a random self taught engineer involved in building my house or a local highway overpass. So why would I also want a random self taught software engineer working on vital computer systems or on autonomous vehicles or on the software that controls the pitch controls on a Boeing 737? Software is not just some shit-tier SaaS app. It being hard to get official credation means accepting holding oneself to high (legal) standards. If that means lots of people have to go around calling themselves a developer instead of an engineer then I'm fine with that.

It might seem depressing that we hold engineers to high standards and expect legal accountability for the things they sign off on or create or approve, but I think more accountability in the tech industry is a good thing. The modern tech industry and software engineers hold themselves to ludicrously low standards because they basically operate on the idea that innovation = good and if-it-makes-money it must also be good. I know fast food workers who are held to higher standards than software engineers. That many continue to call themselves engineers is mainly just a hold over from a metaphor that describes computer systems as "architecture".

Software is a big deal and it effects every fabric of daily life in 2019. We shouldn't treat it like it's ephemeral stuff that has no consequences beyond the next VC exit or going public.
> Obviously it is also a good fit for low scale use cases.

Is this a given? Just because something is necessary at scale doesn't mean it is a good fit for low scale use cases. I would expect the opposite is actually true.
How does it compare to BPM solution like Camunda?

I can assure you that Rod Rinkus', Sparsey creator, work is very serious. He is a computational neuro scientist I've actually been working with him since october. But he has said the website has needed some updating for a while now. One of my primary jobs will be to get the demos up and running with a more updated feel. I'm not sure of the other site, but I have done the work to recreate Rod's work from scratch and he has done several tests to prove the system works. Most of his work was done through DARPA and ONR research grants. He has only really recently decided to try to make a profitable company off of it recently, before that it has always been funded through research grants.

As for the look and feel of the website, which in reality has no merit on whether the research is legitimate or not, I have joked that he just needs to market himself better and he has laughingly agreed. But you can hit him or I up if the research is to hard to understand from a glance. We are trying to practice how to pitch it to people better so it's easier to understand. But once every thing clicks, its actually a really simple concept, it's just that its a highly recurrent system. I had to program it out piece by piece before things started making sense.

Obama is more to blame because he did the opposite of what he promised during his campaign... I don't recall Trump making any promises to reduce spying on citizens... Actually, I voted for Trump because I thought that he would make the breaking point come sooner rather then later (because the way it's going, that's how it's going to end anyways).

And what would be the penalty for not voting. Me not voting is a vote of FU to the whole endeavor. Now police state thugs are going to what, no knock raid my house in the middle of night? Garnish my wages? Take away by constitutional rights? Oh or will it be tax by another name, you’ll get a tax credit with proof of voting. Its all too illiberal and un-American. Sure Australia requires voting but they also voted to remain a commonwealth. The US on the other rejected subjugation. Voting is a right. Rights can be freely exercised. That means either participating or not participating. Compare to the 1st and 2nd amendments. I can speak freely or own arms but I have to do neither. I can keep my mouth shut and remain unarmed.
Your comment is disingenuous to a degree that’s comical. You complain about the use of the phrase Great American Firewall. Unless you’ve been living under a rock since 2016 you should be aware of the fears in Congress regarding “Fake News” and the extent to which Congress is trying to outsource the work of censorship to Facebook and other social media outlets. There are multiple articles, each week, that make the front page of Hacker News, on this very topic.

Nope! You could easily require states to offer a full week of voting as a minimum, this would also cut down on the tactic of making long lines at voting stations to reduce turn out.
Tablets are too big to carry around, and phones are too small to use for non-trivial purposes.

A folding display solves that issue. Small when it needs to be, large when you want it to be.

Yeah, it's thicker than a typical phone, but that's usually not the limiting dimension when determining pocketablity.
I've done some contract engineering work for them onsite. Super professional and talented engineers inside.
Anecdotal but I did linear algebra at a local CC in a "flipped" classroom. We were expected to watch lectures (youtube videos from a MIT or whatever) outside of class and then class was supposed to be a discussion of the homework, which we also had to do out of class and was provided no class time prior to it being due to discuss, in class. There was no real teaching on behalf of the professor. I can't just interject a video when I have a question about the subject matter. I'd either have to wait it out and see if it was answered later, rewind and watch again, or find another video explaining the same concept. All of a sudden an hour long video became an hour and a half to two hour endeavor. Just absolutely time consuming. It came off as lazy by the teacher. To be fair was like his first or second semester doing it but I didn't care to take the class again. Some of the smartest guys I knew we absolutely frustrated with it also. We all gave him bad reviews. Learning should be interactive. This was not. My friend group would basically meet up and teach ourselves the concepts. It was way harder than it should have been.

I'd rather MOOC's be used to supplement a traditional lecture. I know I used the hell out of Khan Academy during Calc 1-3 which were all traditional lectures.
I think the public benifits from that to some degree. A search engine index is inherently a derivative work and without updated legislation could easily qualify as copyright infringement.

I am not saying is fair, but other industries which get away with actually killing people (ex: fine particle pollution from coal power plants). So, bias is somewhat expected from how our system works, it’s just not all bad.
xpaint is pretty much this, though the UI is rather old style and you may have to experiment with it a little bit to become proficient.
OK, point taken. I considered "scaling" in a less general sense (scalar multiple of the unit matrix), while you want to allow arbitrary diagonal entries. My definition is to my knowledge the common one in linear algebra textbooks because in yours, the feasible maps depend on the chosen basis.

EDIT: To state my point more clearly: in textbooks, "scaling" is the linear map that is induced by the "scalar multiplication" in the definition of the vector space (that is why both terms start with "scal").
This human hacks!

'The Media' includes The Daily Mail and Fox News. The general public on average don't want facebook to curb 'their' news, perhaps those other people's.

Washington has been shouting fake news from both sides for a while. Is worth noting that Trump just copied something already being said by others and mashed the definition.
In Vermont there is a state holiday for "town hall day" it's statutory so everyone either is out of work or getting paid holiday overtime and it's meant to encourage people to participate in their local town's politics - it is awesome and everywhere in America should have it.
These phones also come with a warranty for if/when problems do show up.

I expected to see problems, I expected to see some outrage and jokes when things went wrong on the phone, but I never would have guessed at the number of comments saying things like "for $2000 it should never break!". That just seems so silly to me, it's a first gen product with a lot of new stuff in it. Expecting it to be perfect at any price is unreasonable.

Sure, if they stop honoring warranties, then I'm all for the bad press. But as of now, it seems like they are handling it about as good as I would expect. They delayed the launch, are looking into the issues, and will hopefully resolve them. Don't get me wrong, it's a horrible look that the review units broke so easily, but the phone also isn't out yet.
Looking at a few comments, can someone answer on whats are the nuances between managing data workflows vs service workflows ?
This would make life truly hellish for Web developers: your app randomly gets terminated on client machines that are temporarily sluggish. Lots of them would just give up on the Web and write apps for other platforms.
Money has inconvenient qualities for those in power:

1. Actually using it results in parting with it (rather than being able to merely present it over and over)

2. Money held by outsiders is just as valuable as money held by insiders (giving outsiders independent power)

#1 is mitigated by the inflationary treadmill policy, and #2 is mitigated by oxymoronic "money laundering" regulations. But the authoritarians in power are always seeking new ways of eroding distributed paradigms.

It's the Precautionary Principle.

The odds may be low, but there are vendor lockin scenarios that sink a company fast. Having experienced that once you don't want that sense of powerlessness again.

The part where I agree with the sentiment in this chain is where people try to avoid this by putting in big abstraction layers of custom crap.

It's possible to use Law of Demeter principles to keep the vendor details of a lot of subsystems from leaking across your entire app. But that requires architectural skills that are de-emphasized in the Ship Every Week world we live in.

(I'm not implying causality there, or maybe the causality is in the other direction. These things are hard to learn and harder to teach and if you can't get one thing you try something else.)
Some of the other stuff (the firewall) is clearly incorrect, but after thinking about this a long time, I think it's fair to label the current administration as having some fascists or fascist-curious/adjacent/whatever people. Authoritarian works too.

Often, the term gets thrown around too freely by those on the left when they want to disparage someone on the right whose ideas they dislike, so it gets overused.

But I think with the disdain for the rule of law, friendliness and admiration of rulers who are certainly authoritarian, and the push to "believe in me, rather than your lying eyes", the term has a place in the conversation.
Controlling the news feed on one site is not nearly comparable to a universal firewall... Many people already have stopped using Facebook

The housing bubble is far from being played out.

In most desirable-to-live places, prices have recovered and gone above and beyond 2008 levels. Of course it's really the value of land and not the structure itself, but still, the scarcity aspect remains unchanged.
While I am skeptical as well, there are a few other scenarios that aren't being considered in your napkin math:

- Selling items other than crepes: coffee, tea, alcohol, soft drinks, snacks, etc all have great margins.

- If the place is a cafe, customers may stay and work/read and run a tab, increasing the average revenue per customer.

- Multiple customers may arrive as a group and run up a higher tab.

- Multiple locations: compounding revenue, higher reach, etc

There are probably many more things I'm not even considering.
Sadly, there are. Or at least were.

When I went through university the standard set of courses was a Calculus course that was mostly about derivatives, a second one that was mostly about integrals, a third Calculus course that was about multi-variable Calculus. That third course necessarily had to teach matrices, and taught it as rote calculations. There was a follow-up differential equations course which refreshed people's memories of matrices..as a rote calculation.

It was done this way because the multi-variable Calculus course was a prerequisite for a lot of physics+engineering courses. So a lot of students wanted to take that sequence. Differential equations were a prerequisite for some other advanced courses. Linear algebra was pretty much just for math majors.
> We already have a social credit score. It's called FICO

There is a material difference between FICO and what China and, potentially, Facebook are building.

FICO looks at financial factors. It's a model to estimate likelihood of repayment. Being brown or gay or female might correlate with factors that reduce the likelihood of repayment. But if those systemic problems were fixed, and FICO were left unchanged, it should yield an unbiased result.

Social credit scores, on the other hand, directly incorporate biases. Introduce a social credit score into an economically equal society and it will redistribute from the "undesirable" to the "desirable" based on zero economic facts. (Same with ad-driven social networks like Facebook and Instagram.)

It's subtle. But it makes a world of difference in terms of effect and the moral culpability of those who choose to support its development and deployment.
I'm actually finding airflow + beam + kubernetes to be a really powerful combination. Especially if you're on GCP where airflow is managed by Cloud Composer, kubernetes is managed by GKE, and beam is managed by Dataflow.

Our airflow cluster _does_ almost nothing. Our operators just tell kubernetes to run containers with commands or dataflow to run some beam template and waits for the results from afar.

I love this setup but man do I agree with your points about the UI. For a product so powerful I can't believe how problematic it is.
