Not true in that absolute: There is tons of freely licensed music out there. You can find free game assets for genres that are somewhat "generic". But still it is a thing, a few theories on contributing factors:

a) More typically an individual work, with one person having a vision that they do not want to have compromised by others. Arguably harder to have contributions in a way that doesn't stand out in many cases, which means one work made by a small army of contributors sharing the workload doesn't happen often.

b) the "work for me for free" demands are worse for artists than for coders. "Freeloading" is seen a lot more critically/abusive than in software circles. (although it does happen with open-source projects as well of course, and long-term maintainers burn out accordingly as well).

c) approximately nobody pays artists to produce freely licensed works

d) free work by artists might be in direct competition to their ability to make money from their art.

e) Parts vs final product: a lot of open-source development is in pieces that other projects build on. Similarly, you can find quite a lot of "pieces" of art for free: sound templates, stock/reference images, textures, ..., which is not very visible to someone looking for "free graphics". Similarly to how many people not involved with software do not understand on what mountain of free libraries a lot of software stands.

f) More visible if reused, which leads users of graphic resources to want individual ones instead of the same as everyone else. E.g. games will more likely stand out by graphics but use the same engine as X other games.
It's a great question. No kidding. Of course, you can since you can build the first piece naturally, then get the second from a pair of points and a derivative of the first, and so on. But it would generally oscillate as hell. The trick is - if you're approximating a parametric curve, you don't want derivatives to actually match. You want the tangential continuity, which is a proportion of dx/dt and dy/dt derivatives and not the exact number. So if you just tame your derivatives a little, you would still keep the tangential continuity and not let the oscillations loose.

Ask HN: Any tutorial that explains the secure way of doing user authentication?
So I am a beginner, working on my first project without any tutorials. One thing I am stuck on is how to do user authentication, most resources I have found till now explains how to use a particular lib for authenticating users, but my concept behind authentication is still kinda foggy. What I am looking for is an overview of what happens or needs to be done for user authentication in a language agnostic way.

No, that's not what I'm saying at all. It doesn't matter how well they "performed". What matters is: would they have chosen that profession if they weren't placed there? Could it be that men preferred computer-related careers more than women did? If so, then the fact that many women were placed in those careers initially is completely irrelevant to the question of why there aren't a lot of women in those careers now.

I can't find the source right now, but drivers have been privileged versus pedestrians since around 1900 when vehicles were given the right of way instead of the pedestrian who had it before.

If Amazon drops prices to a significant loss on a single product to specifically undercut a new competitor, that might be an issue.

>Only when it comes to things that the right is is indisputably on the wrong side of history and hasn't figured it out yet (gay rights, gender rights, etc).

Except that's not how it works the other direction. You mentioned communism. The left is indisputably on the wrong side of history here and hasn't figured it out yet. And yet somehow the right is still willing to engage in reasonable discussion.

A person could take a generous reading of Damore's memo and find plenty of common ground. It doesn't matter if he's right about the differences between genders being biological vs environmental. Survey after survey suggests that part of the reason why women avoid/leave tech is long hours and inflexible schedules. Since men are more willing to accept long hours and inflexible schedules (again, could be socially constructed) then Google is currently set up to maximally benefit men (patriarchy). To help with this situation Damore suggests some new policies like creating more part time positions and offering more telecommute opportunities.

But instead of trying to find common ground and move forward with some policies which might create an environment maximally beneficial to everyone, the ENTIRE NATION needed to stop what we were doing so this socially awkward nobody with no power could be publicly flogged over some potentially incorrect ideas about diversity policy.

The origin of soft skills
disclaimer: not medical advice, please consult opthalmologist

There is a genetic component to myopia, i.e. two people can have similar closeup/distance/light exposure as children, yet only one develops myopia. If you are genetically (nature) susceptible to myopia, then lifestyle (nurture) plays a role in development and progression of myopia. Lifestyle factors include:

% of closeup vs distance vision
reducing uninterrupted closeup time
increasing viewing distance
light quality/intensity: >10K lux natural vs artificial
self-awareness of eye strain signals
outside distance vision (especially with motion)
sports with fast-moving objects, e.g. ping pong
use of full peripheral vision

Good vision depends on the visual cortex of the brain which processes signals from the physical eye. Software and hardware. There is a complex feedback loop between the brain's ability to correct small errors vs. eye muscles accomodating to change focus and direction. The most advanced work in this area is vision therapy for veterans with TBI (Traumatic Brain Injury).

Neuroplasticity means that the brain/software can be upgraded with vision therapy. This is most effective with children where both the brain and eye are still developing, but it also works with adults. However, it is much more expensive than eyeglass correction and thus requires special insurance coverage for behavioral opthalmology. It may be covered by national healthcare.

https://aoa.org/patients-and-public/resources-for-teachers/a... says: "Reading requires the integration of a number of vision skills: visual acuity, visual fixation, accommodation, binocular fusion, convergence, field of vision, and form perception. The typical school eye chart test only evaluates distance visual acuity." This means a child can pass the "eye exam" (visual acuity) test and still have vision difficulty, causing an incorrect diagnosis of learning disability.

Why wouldn't you punish people who illegally hacked your countries companies at high cost to the companies, and by extension your citizens. Especially when the actions are illegal in that country, illegal in your country, and illegal by treaty that your countries are both part of.

The reasons not to have them indicted are "we don't want to keep the rule of law" and "we don't care about costs to our citizens" and "screw democracy, we want to play with the pawns too".

Yes, there is zero chance of extradition because such people give less than two shits about rule of law and democracy ... but that's exactly why one should care. They should evict all our UK government personnel from Belgium.

In my opinion online education is failing because:

1- people are not accustomed to it and online education companies do not spread a "methodology" to approach online education. Students that need help are supposed to at least use discussion forums but often they don't

2- online education target the low hanging fruits, usually offering "just" master's degrees. I dreamed to be able to get my bachelor's by an accredited institution, on-line and for a reasonable fee but that dream never came true.

So at least in my opinion, online learning didn't really happen: the promises of "disruption" and "revolution" haven't been kept.

You still need to go to a regular university to get a bachelor's degree, and then you can (maybe) enroll in a master's degree, assuming regular universities aren't better/cheaper than online ones.
The issue here is a point of view: Freedom technically means free of constraints, which is the US view. However, many people (me included, BTW) interprete freedom as in "freedom of choice", that is, a society that enables more, not less choices of going about your life. Sadly, total freedom (in its most literal definition) is ultimately equal to anarchy...

No. A police officer can politely and non-violently deal with a citizen.

As for the military... I've met some Special Forces officers. They were dedicated and crazy-smart (senior NCOs), and I'm happy to pay them to do their jobs, and possibly even call them friends, but they should not be police, and I don't think they would want to be.
I agree with you on principle and wish I could do that. I already protect myself quite a bit from Facebook.

I don't even use it to post any personal stuff, and use it for specific social causes and some events around that. I can't avoid Facebook (though I hate the company and its practices) because this is where most of my target audience is.

> So awesome that Red Hat Linux even deprecated it.

They never "supported" it in the strict meaning of the word, it was only a technical preview and they dropped it from technical preview. That's different from "deprecated" (let alone that Red Hat doesn't have the power to deprecate things in upstream Linux). Not to mention that most/all of Red Hat's btrfs engineers moved to other companies (like Facebook) so nobody was there to maintain it.

The more forward-thinking reason for dropping it is that Red Hat is putting all their eggs into devicemapper+XFS (in the form of "Stratis"[1]), so why would they expend engineering resources on more projects than necessary -- especially when they'll probably want customers to switch to Stratis rather than keep them on a never-actually-supported-by-them filesystem.

Reminder that the FDA seems to fast track the wrong drug:

They gave "breakthrough designation" ( https://en.wikipedia.org/wiki/Breakthrough_therapy ) to Esketamine under pressure from Johnson & Johnson:

https://en.wikipedia.org/wiki/Esketamine#Depression

Although Arketamine seems like it has a lot more responsibility for the antidepressant effect of racemic ketamine:

https://en.wikipedia.org/wiki/Arketamine#Novel_antidepressan...

https://en.wikipedia.org/wiki/Hydroxynorketamine

https://www.ncbi.nlm.nih.gov/pubmed/24316345 (2013)

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5487269/#__sec4... (2017)

That isn't to say Esketamine doesn't have an antidepressant effect. In light of the fact that Esketamine makes you Trip Balls(tm) while Arketamine doesn't, I like to think of it this way:

You can likely get an antidepressant effect out of Esketamine in the same way that you can get an antidepressant effect out of psychdelics like LSD-25 & Psilocin. However, like those, it could possibly also make depression worse, and unlike Arketamine doesn't seem to represent anything awfully novel. It however also makes me suspect that like with other racemic drugs like Amphetamine, a shifted ratio preparation might make for a better drug overall than isolating the stereoisomers. For example, Adderall contains 75% dexamphetamine, 25% levoamphetamine, in the form of various amphetamine salts (wheras racemic amphetamine contains 50% of each, typically as a single salt.).

[Semi-related: I still don't comprehend why pharmaceutical companies have yet to create a combination preparation of Lisdexamfetamine with something like Lislevoamfetamine, - which I haven't seen synthesized but I don't see anything speaking against it -, in a ratio akin to the one seen in Adderall. The rational behind that ratio seems sound, albeit I'd perhaps go for an 80/20 split instead of a 75/25 split...]
