If you added up all the R&D money spent on these self-driving features, we probably could have already covered 80% of American roads with simple guidance systems that would assist in piloting cars safely. Then nav systems wouldn't need to be as complex, and wouldn't depend so much on trying to guess road factors.

If self-driving really is the future, the government's going to need to be involved, the way it is in building and maintaining roads. Many roads already have cameras and sensors built into them just for measuring traffic, so it's not a big leap to say it should also have tech to improve automated driving.

It reminds me of the "sounds like a bad idea" / "is a good idea" Venn diagram for startups.

If it sounded like a good idea and was a good idea, then a bunch of people would have already tried it. There would be steady progress by many people, and steady competition. There would be no "breakthrough" by a single person / company.

If it sounded like a bad idea and was a bad idea, then either nobody tried it, or a contrarian tried it and quietly failed.

I think people mistake this as an attempt to tell people to get rid of jQuery. No, that's not the point of these webpages.
jQuery still offers an overall nicer API than native. If you're building an application, and have to make the choice between using jQuery and going native, go pick jQuery.

However if you're writing a 10 line script that does something really small (eg. if you have a static webpage and need to make one button slightly interactive) then these guides tell you how to do it without importing all of jQuery.

I think the quality of the average HN user is pretty high, but obviously this might attract low-quality proposals. Honestly every offer to code someone's idea will (I've been there, and fallen for it more then once), take what "nithin001" posted as example.

This isn't the way to find the next Steve Jobs indeed, and that's not what I'm searching for. I'm looking for that consultant that has seen 4 clients wasting 8 hours a week on the same inefficiency. Someone who will get $2k for an idea and a number of phone calls, and a large kickback for sales (s)he makes in his/her direct network. This isn't the way to kickstart a $1bn company :)
Yes, but it's even better than you think given that you can find ryzen 3 at the price point that used to be modern "pentium" playground; Windows 10 and a browser with a few tabs and office with a couple spreadsheets opened just don't do well on two cores anymore

And in fact ryzen 5 2200/2400 is so cheap that competing offers price wise are i3 based (or i5 but with less ram, and 4 GB is just not enough in 2019, when windows want 2, chrome wants 2, office wants 2, ...). Ryzen 5 2xxx vs i3 is simply not a fair fight, it's not even a fight at all.

I guess I'm usually so focused on high / super high / server needs that it didn't fully hit me how intel was getting eaten alive even in the low / middle market right now. And medium sized business replacing office computers really don't care about the brand of their cpu, "cheaper, works better" is going to win every time.
Is it? I would say Waymo is a lot closer to being the poster child; a significant number of people have realized that Tesla isn’t true self-driving despite their claims.

The existence of dark matter in galactic halos is inferred from the velocity dispersion of stars in a galaxy (sigma). It’s important to realize that this is a very rough kind of estimate because every aspect of it (as in the case of the M-sigma relation) is roughly estimated. Virial mass is inferred from average temperatures of gas by way of detexting X-rays. Central black hole mass is inferred through the M-sigma relation, and stellar masses are inferred through luminosity. Every so often a new paper comes out revising the overall estimates, but the proportion of DM to luminous matter stays pretty constant.

Now, in a sense this makes a “selfie” easier, because you just need a series of snapshots which help you make all of these inferences. On the other hand because we’re in the disk of our galaxy it is difficult to image because we have to deal with all of that hot interstellar gas and dust, and the extremely bright galactic core. I’m not sure how much, when you take into account a long period of time and many wavelengths can be observed, but I’d say we can observe the majority of our galaxy in at least one wavelength. Still, we’re not talking about “selfies” here, just really well educated guesses based on observations of our own galaxy and similar spiral galaxies.

So as far as inferring the existence of a dark matter halo in our own galaxy we’re pretty certain, and it seems to make up about 95% of the galactic mass. It’s based on something a lot more tenuous and complex than a “selfie” though. Once you’ve done your best to estimate the total luminous mass of the galaxy and it’s rough distribution though, and ruled out MACHOs with lending surveys all that’s left in the remaining narrow window is dark matter. The only other theory with any chance at all is MOND, but it has to thread crushingly narrow passages between observation and tests of GR.

> If you like, but that is not how sales tax works.

It frequently is. In many cases it goes the other way, e.g. if you buy a PC for $1000 and pay sales tax on it, and then you sell it some years later for $200, the buyer often doesn't owe sales tax because you already paid it when the PC was new. And when a business buys a product as inventory they don't pay sales tax on it, because the customer will.

It's generally not a good policy to charge the same tax twice on the same product. But that's not even what we're talking about here:

> My point is that taxing economic activity that is not in cash form (such as trading shares) is not generally considered unreasonable.

My point is that it isn't doing that.

You can't avoid income tax by having your employer buy you a car. The value of the car just becomes taxable income.

Deferring taxes when securities are exchanged isn't doing that, because your tax basis in the new securities would be the same as it was in the original ones. You still owe the tax whenever you want to sell the securities and spend the money.

Doing it this way would also allow you to get rid of a lot of the rules that really do reset the tax basis, like the one that happens to inherited property. The concern there is that property inherited through generations would have a tax basis of nearly zero, so the entire value would be taxable income and that amount of tax would make it uneconomical to ever sell the property, even if continuing to own it was highly inefficient. But if you could exchange it for another investment vehicle of equal value and just transfer the tax basis then that wouldn't be necessary and the government could continue to defer the tax obligation rather than waiving it entirely as they do now.

I am not surprised that their inclusion was sneaky. I recall when Intel attempted to market TPM for the first time. The reaction was swift and very negative. Slashdot was not in favor of 'security' through including security holes and relying upon obscurity of the information on how to exploit the holes being the single point of failure. It was closer to when the government was trying to mandate key escrow and Clipper chips than now and back then they had to walk it back and not release it with a high profile. Back then the most common worry focused on was that this would be used for hardware-based DRM in service of the entertainment industry.

I definitely appreciate every free software maintainer out there. Hats off for your hard work.

What I appreciate a bit less is a burnt out maintainers that does not ask for help and has his hands full. Hats off for your hard work, we use your library and we want to help. You are not alone.

What I dislike is a burnt out maintainer / not so great person of multiple important libraries of a popular language that randomly closes issues and PRs without explaining the reasons and then blocking people once asked why he did close an issue that was still relevant.

If it's a personal project open sourced, sure, you have the absolute freedom to do whatever you like. If it's a multi-maintainer project that has a huge piece of the market, then that's absolutely not okay - it causes a toxic environment that only damages the library and it's future.

PHP is doing great! I like the direction it is going in. PHP 7.4 also introduced nice features to improve static typing. The FFI is pretty cool too. You also get free performance improvements while remaining mostly backward compatible. It is trying very hard to stay relevant and I believe it is succeeding.

Perl's decline relative to PHP is a bit more nuanced. With mod_perl you had to be really careful with global variables otherwise another process could access them in memory. Mod_php did a better job of isolating processes so mod_perl gained a reputation as a security headache which most cheap hosting companies were not prepared to deal with. It's often overlooked that a lot of cheap hosts only offer PHP as a CGI so the benefits over Perl/CGI appear, at first glance, to be minimal but even as a CGI PHP has templating built-in where Perl, Python and Ruby don't. Perl only has CGI.pm when limited to CGI. Sure, you can try to run Perl web frameworks such a Mojolicious, Dancer and Catalyst under CGI but they're not going to compete with PHP since they don't run as drop-in templated pages. Perl did have a PHP clone - HTML::Mason - but it wasn't worth using unless you ran it with mod_perl. That's where Perl lost to PHP.

When PHP gained full OOP support with PHP5 the Perl community was still tearing itself apart over introducing a MOP and which of the dozen Moose clones should reign supreme. That was the final nail in Perl's coffin, at least in it's bid to compete with PHP.
That looks it merely needs some reflection support (variable name lookup).

While I think the “sovereign movement” is pretty laughable in both theory and action - I think this article smacks of a total lack of even attempting to understand where these people are coming from. It’s the same people that write these articles that are surprised by the vitriol directed at the press or “how trump won”

The real question is what is driving these people to behave in such an irrational way? Might it be the ever increasing reach of government into people’s lives or the fact that many in positions of power in the US seem to think of that the people should serve the government rather than the government serving the people...

For sure, but you're asking someone else to shift their hours, are you happy to shift yours.

Whilst there's an economic element there's a large social/family element to the consideration which is why, IMO, you don't see many services time-shifting: particularly dentists where they are relatively well paid and usually able to direct their own hours.

Example I work in an SME that could make much more money working Sundays, but we choose to close and be with Church and family. Same sort of consideration; valuing social aspects far beyond their monetary value.

Not everyone will be happier with business hours expanding, especially low-wage workers I expect as the expanding hours will lead to lower QoL.

Well said. I should add that as an entrepreneur you don’t have to work for some moronic boss or organization. Bearing in mind that if you employ anyone, then you may be it. Either way, this is a biggie for me.

Vice writers are unionized and are thus profiting from pro-union laws that allow them to undermine the contracting rights of their employer and get themselves above-market wages. Therefore the angle they choose for this article is not surprising to me.

Whatever happened was probably entirely legal and probably ethical as well.

You can be a cofounder, and have ownership even if there is a lack of contracts and paperwork, and that likely would have come up during that $500M acquisition. I can't find it, but there was a Ycombinator - backed startup whose sale was blocked by a founder who went AWOL early.

If he was an employee, or did otherwise hand over / accept compensation for his work, well, that's just business as usual: employees generating wealth for owners.

The lesson is to have clarity of what you want out of a certain work, and then have some kind of contract, before you start working.
I wasn't aware of Common Lisp type declarations, thanks. But they are optional (right?) so in practice if they are not there they do little good.

Could you tell a bit more about how generic functions do the same thing as Interfaces? Can you use them as part of a type-declaration? Say like a Java Interface can be used as a Type in a type-declaration of a method.

> Hanzi Writer uses character data from the Make Me a Hanzi project
The ban in California has backfired, in my opinion. Many stores, including major chains like Safeway, still give out plastic bags. However, they are very thick plastic that they call "reusable" to get around the law banning "single-use" plastic bags. It obviously goes against the intent of the law.
> Better documented is better.

I was talking to some kid who wanted to be a developer, and I echoed this sentiment. A complex tool with good documentation is easier to use than a simple tool with bad documentation.
Exactly. The main downside to plastic bags is not the carbon emissions or landfill contributions, it’s just what the OP said: ocean plastic and street litter. Each factor isn’t equally weighted.

Isn't reflection slow as hell?

If not please correct me.
I think you've answered your own question. Between working one hour out of the day, or ten minutes out of each hour, which is actually more feasible and likely?

In a day rate situation, if you're blocked by client inaction, they're still paying you daily. In an hourly situation, that is generally not the case. And if you can truly satisfy client obligations working only an hour a day (very unlikely), then yes, you'd still get paid for the days and there would be nothing unethical about it.
Sovereigns start out by taking the classroom taught non-controversial idea of self determination to its logical extreme (every individual a country unto themselves). They don't need a foundational document because they believe that not answering to anyone is the natural state and therefore needs no deceleration. They further conclude that unnatural states (re: being born into someone else's rule) must be the result of some form of scam or trick. It has appeal because on the surface it is logical and congruent with things you learn in school.

Sovereign's go from extreme libertarian to crackpot in their explanation of why the world doesn't match their description of the natural free state. They invent an elaborate story of paper people and corporations and conspiracies to act as a sort of dark matter that makes their theory match reality. Soverign's can have wildly different takes on the dark matter while still agreeing on the core ideology.

Soverign's are basically just magical thinkers who happen to be libertarian.
> because of dark matter's lack of electromagnetic interaction

This is still an assumption, because we don't know for sure that dark matter is only weakly interacting, but this is what was observed in the Bullet Cluster collision: https://en.wikipedia.org/wiki/Bullet_Cluster

There's a good explanation here: https://astrobites.org/2016/11/04/the-bullet-cluster-a-smoki...

The lensing was found to be strongest near the visible matter (stars), and the amount of observed lensing couldn't be accounted for with the total stellar mass alone. So the assumption is that the dark matter, like the stars, wasn't slowed much by the collision. The gas, on the other hand, interacts electromagnetically and slows down in the middle.

That's not to say that the stuff that stars are made up of isn't affected by electromagnetism, but it's a short-range effect and even in a collision, interstellar separation is large (i.e. contrary to what you might think, a galaxy collision doesn't involve all the stars smashing into each other, most of them will just sail right on through). Gravity will dominate in that case.
There always was too much out there in the last decades, and a majority of people looking for "universally good" things, reassured by knowing that everyone else approves it and enjoys it.

I don’t know anything about Gavin. Not that I particularly trust journalists but they are supposed to be neutral third parties reporting facts.

I agree that something that I didn’t say would have been disingenuous, but I’m not sure why you would bring it up.

I’m sure you would agree that it being an op-ed tells us primarily that this article was not written by a neutral third party. We would not be surprised if it makes little to no effort to present opposing views. As an op-ed it is free to make unsupported conjectures and should probably be approached with a higher bar of skepticism and should be expected to provide facts or evidence to back up any of its novel claims.

In short, op-eds are not news, and should not be treated as such. Not that “news” is particularly deserving of the distinction these days.

I said simply that we should not take op-ed claims at face value. You said you don’t agree at all. I mean, you are perfectly free to take the claims at face value if you like, but appeal to authority is hardly compelling and perhaps even a bit disingenuous itself.

“This argument has been made for over a decade, now, with no satisfactory counterargument coming from detractors of dark matter. It isn’t the displacement of gravitation from normal matter that “proves” dark matter exists, but rather the fact that the displacement only occurs in environments where dark matter and normal matter would be separated by astrophysical processes.”
