A perfect example of Betteridges Law (and a very clickbait title): no, every speed limit is not too low.

The article implicitly accepts the conventional 85h percentile rule as defining correctness, and it's the single most common rule used to set speed limits in the US. Yes, some are below because of rounding rules, and some are below because of special safety conditions (in California, in general, these allow 5mph downward departures), because of specific legislative exceptions (school zones), or because of state maximums (which mostly affect major highways, not city streets).

And, outside of restricted-access highways, while the 85th percentile rule may be ideal for automotive traffic alone, there's a reasonable case that it's too high for mixed uses. [0]

Microsoft does deserve some blame for deciding to support backwards-compatibility in-situ instead of introducing proper API versioning, packaging, isolation, and other proven techniques. Win32 wasn't versioned for processes until Windows 7 (using app.manifest) even though the need for such as system was blatantly obvious during the Windows 2000 days.
Every single person I know in software has a decent job and I'm having a hard time finding good people. We're slowly increasing staff, but it's hard. Back in 2008-9 I worked somewhere that was hiring a LOT and the problem was just sifting through the mountains of people after the crash. This is the complete opposite. Part of the problem is internal - since management wants to operate very lean we need to find really good people, but there aren't very many average ones showing up either.
Your experience is directly contradicted by what people studying this observed as the national limit was relaxed and then removed completely.

It's hard to think of any problem that would be more important than the problem of not having users.

Very nice article! I've been willing to delve into Bézier curves for a while now, and this looks like an awesome reference to start.

I'd just like to make an annoying mathematician comment on the beginning (paragraph 3): you might want to point out that the first definition you give of Bézier(n,t) is, for any n and t, nothing else than the constant function 1 (that, by the way, is an absolutely fine polynomial, unlike the statement above that if f(x) has no x then it's not a polynomial).

You can see this by noting that it's nothing else than $((1-t)\cdot t)^n = 1^n = 1$. If you insist on being fancy, you can say that the i-th term in the sum is the probability of a discrete random variable X with binomial law being equal to i, so the sum over all i must be 1 (here the binomial law has parameters (n,t)).

By the way, this last thing has the nice interpretation that each point of the Bézier curve is just the expected value of $p(X)$, where $p(0), \dots, p(n)$ are the points you are interpolating - by changing t you are just changing the parameter of the random variable.
I think you're attacking a straw man - this situation is nothing like the typical pattern of "acquire company, shut down the product". Hackpad has been running for years since it was acquired (everyone in our company uses it regularly). Dropbox Paper is basically a newer, better version of Hackpad. Anyone using Hackpad can "upgrade" by moving all of their pads into Paper. We just moved over - it was easy and cost nothing.
I just returned from a 2 week driving trip through Germany and vastly preferred driving there to driving in the U.S. The "always pass on the left and never on the right" seemed like it led to more systematic and predictable behaviors, and also tremendously reduced the competitiveness of the driving experience as compared to the U.S.

It might all be cultural differences though. I noticed drivers seemed more attentive and never used their phones (unless completely stopped in traffic jams), whereas here in the U.S. it is extremely common to have drivers piddling in the left lane and absolutely oblivious to the goings on around them.

The only stressor I could see from driving on the autobahn was easily overcome - before passing someone on the left, just be sure to check really, really far back towards the horizon to make sure one one is coming.
Playing the stock market is just one facet of investing, and a widely-discouraged one at that (e.g. market timing). Long-term investments favour index trackers so that you can gain from the performance of the market as a whole.
The problem with US public transit is not its interregional distances, but the low density of its regions. Diffuse populations defeat transit. People in those diffuse regions are more likely to utilize cars for midrange travel because the time to reach transit is high. In many regions, this means that transit is only for people too poor to have reliable cars, introducing another problem.

That we have any American cities with decent transit seems to be largely thanks to the restrictive geography of those cities, as well as some excellent activists (Jane Jacobs being the easiest example.)
There's a difference between having "a single standard", and having "a few popular ones" (which Exchange contributes to).

The big downside it that apps still need to either support two protocols, or live inside on of two bubbles. I really with Exchange would adopt IETF standards (but I guess that's not in their best interest).
Hmm, on a related thought, how could self driving cars ever work there?
From everything I've seen and read, these positions are becoming more and more rare.

> I don't think the main problem is that speed differentials are causing poor dynamics, but that the roads don't have enough lanes.

I don't know.

I drove throughout Germany a few times last year, and I didn't really understand why there were so many jams and general slowdowns. I usually drive in France where the highways are almost exactly the same as Germany (most often two lanes, frequently three, rarely more, usually in very good state) and traffic is rarely as bad. I got stranded a few times in completely still traffic, for tens of minutes, during a normal working day, while this only ever happens at the worst time of holiday traffic in France.

Maybe it's because French highways are paying which probably discourages some drivers, but I also noticed a lot of roadworks in Germany (almost as bad as Belgium during the height of roadworks there last year). Enough, as you said, to never be able to maintain a high speed for long, while you barely ever notice those in France. I don't know how French companies do it, but I'm pretty sure it helps with the traffic.

Other than the traffic though, driving in Germany was a pleasure. People are aware of their surroundings and don't drive like the road was theirs.
It varies by state; in California the unauthorized practice of law is a crime.

Perhaps predictably, the people complaining about this feel that it's a form of rent-seeking by incumbents, but none of them have bothered to consider the flip side of the equation which is that bad actors who falsely hold themselves out as licensed professionals can hurt would-be clients in two ways: by directly exploiting them for the cost of services which they are not licensed to provide, and by jeopardizing their longer-term interests in a way that might severely impact them in the future.

Obviously this gentleman is not running around trying to scam Oregonians into paying for cut-price engineering work. But publicly asserting that you are licensed to practice a profession without actually being so, especially when licensure is generally easy to obtain, creates the potential for public misunderstanding. The point of the fine is not to impose a serious financial penalty (hence the token amount of %500) but to draw the public's attention to the fact that anyone holding themselves out as an engineer needs to be licensed within the jurisdiction in which they are practicing - and practicing on your own behalf is still practicing and indeed widely considered by professionals as a kind of marketing.

Considering that the annual fee to practice as an engineer in Oregon is only $75, and that engineering is well established as a profession, I don't think his complaints have a whole lot of merit. Last time I looked engineers are required to take ethics classes as part of their education, and in many jurisdictions keeping ones certification up requires a certain number of hours spent in continuing education each year, same as in the medical and legal professions. If you're not actively practicing your profession then you have, legally speaking, retired and should not present yourself as being currently licensed.
> The evidence seems to suggest that raising speed limits slightly increases fatality rates, but not accident rates

Accident rates are only a concern because of harms from accidents, including, most especially, fatalities.
I don't know where to start with this. The whole point of the truck is to get the workers! to the site. Said vehicle is also there to support the workers during the day with storage for tools and materials. SO no, the damn truck isn't going to replace a plumber or a/c tech. wow.
So what do you do when you have a ton of money? You can of course spend it on charity or investing in companies, but that requires work, and is not in everyone's interests. There are also only so many expensive things that they can buy in this world, so they buy all of them, and some more, and there is still a lot of money left to spend. Even if they do all of the above, there will be more money left, and the search for purpose and meaning will become more and more intense. Also, due to the nature of capitalism, the rich can't stop making more wealth than the rest.
Interesting. I agree with almost everything. Still think search is huge. A highly customizable, secure private search engine. Your own pagerank.

You jest, but given that the average lifespan is about 622k hours, I think you can have a serious moral argument about whether it's better to kill one person or make a million people late by an hour.
Because, over the long term, it would reduce the selective pressure on the ability to gestate embryos in vivo, unnecessarily increasing dependence on technology.

We should try to avoid adding extinction to the list of consequences of the collapse of technological civilization.
> couldn't we just put speed cameras everywhere and issue tickets automatically for people who are driving too fast?

There are stretches in DC with exactly that strategy. As a consequence, people speed and then hit the brakes right before the cameras.

I'd love to know the accident stats right around those stretches.

Google's CalDAV implementation does not expose todos/reminders. Trying to upload one results in an error.

Are you sure it's not just events, and not todos (CalDAV does both, as per the original spec).

Google's CalDAV auth is also VERY user unfriendly. FLOSS apps are not allowed to include API tokens, so end-users have to sign up as google developers, and get their own API keys, which immediately kills UX.
They aren't mutually exclusive. Existing roads are wide and straight and have too-low speed limits. Revamping them to be lower speed roads takes more money than just fixing the sign.
What is ridiculous is that in many European countries speed limits haven't changed since the 70's, when cars used to be a lot less safe and driving education was a joke as compared with today's standards.

You can see that this holds true when looking at some of the Eastern European countries that only recently got better road infrastructure. E.g in Poland, the max speed limit at a highway is 140 km/h, whereas countries like France or Spain keep lower limits (130 & 120 respectively).

I think that today, any highway limit below 140 km/h is just obsolete and should be revised. Now, I would prosecute harder those who speed in urban areas, where the risk of hitting pedestrians or cyclist is real.
Great library, and great documentation! Thanks for sharing :)
So now what do we tell our kids? "Don't get into a van even when nobody is driving it." ? :-)

I think it is great that they are getting additional exposure to nominally real world users here. However, I'm not exactly sure what they are learning in user behaviors. Is it "Can we make a less expensive livery service?" or is it "How freaked out do people get in self driving cars?" or is it something else?

I went to a conference last week where there were several talks that were pretty critical of self driving 'hype' given the HLS[1] issues and the ability to inexpensively 'spoof' the AI[2] to see something that isn't actually there (road signs being particularly vulnerable). It left me thinking I might be more optimistic about the technology than I should be.

Personally I prefer a digit "touchpad" and 24h digital entry - just as for entering phone numbers. So "why not let me type it (on my smart phone)?" is a perfectly sensible question for me as well.

But see the comment above about pro-digital possibly being a vocal minority - we very well could be.

I suppose there's a big difference with never really growing up with analog clocks, and being used to relate to analog clocks for time keeping. All my watches were casio digital clocks, set for 24h display - similar with alarm clocks. I readily think in terms of 24h, not 2x12.

[ed: I'm also used to be able to tell the time by the sun for 24h two months in summer - 0100 being due north with dst (ironic, but true) - just as 1300 is south, 0700 is East, 1900 is West.]
Johnathan Haight's conclusion about the universities suggests that the slow shift of large institutions to the left can't be explained by geography alone.

Unless you suffer from social anxiety, you improve your social skills just like anything else - with intentional practice.

If you want to be better at small talk, make small talk any opportunity you can (or become an Uber/Lyft driver, tour guide, or some other job that requires you to use these skills). If you want to be better at flirting, flirt. Make note of when you're practicing, try and look for social/body language cues and make adjustments. Replay the conversation later in your head and figure out places you can do better next time. Then try again.
Yeah, the difference is that "positive psychology" is scientific field, and they haven't discovered that "thinking positive" helps with being more successful. I changed the title of the sub-section.
I've thought about that. Just 8 or 16 cores running LLVMpipe should be able to do quite a bit of basic graphics. Certainly enough for a RaspberryPi type SoC.
>The startup agenda is either make a billion dollar company or go home.

It's not just startups. Every publicly traded company is focused on growth. You could have many billions of revenue and billions in profit, but if you aren't growing you're failing. I don't agree with this, but the stock market certainly does.
The myth of software development time estimation
Not compared to anyone, you don't need to compare to someone to make a statement that outside of tech, Zuck isn't that well known.

It would surprise me to see millennials vote in swarms at all, that fact that young people generally don't vote is one of the big problems and always has been. Young people don't choose government, they're too busy being young; it's older people that show up and vote and largely always has been which explains the demographic of congress.

MZ isn't a politician, and I don't think he could win because he doesn't have the personality required of a politician and diplomat. Trump didn't win on anti-establishment, he won on racism pure and simple and that was born out by the numbers. He ran a nasty divisive campaign invoking the worst in people and it was just enough with our wacky electoral system to win despite losing by millions of votes overall.

As for your summary of the left, well, it's just an unhinged partisan rant not grounded in any facts and not worth arguing with.
From your link:

"However, it is important to make a distinction between a "graduate engineer" and a "professional engineer" or "licensed engineer." A "graduate engineer" is anyone holding a degree in engineering from an accredited four-year university program, but is not licensed to practice or offer services to the public. Unlicensed engineers usually work as employees for a company, or as professors in engineering colleges, where they are governed under the industrial exemption clause. Some states, such as Ohio and New Jersey, prohibit the use of the term "engineer" by an unlicensed person unless it is part of the internal classification of their employer."

So you don't need a license to call yourself an engineer. What this effectively does is permits engineers to perform engineering tasks and be called engineers in their line of work, without having to complete the examinations and all of that jazz. Otherwise, the entire system makes 0 sense. Furthermore, this demonstrates that you may call yourself an engineer if you have graduated from engineering college as you are under granted the title "graduate engineer", and thus can use engineer for shorthand, just as "engineers in training" and "professional engineers" may call themselves engineers for short. I doubt they want to always have to call themselves professional engineers or engineers in training or face a silly fine.

Though I do fully support requiring licensure for some engineering related work. Basically, if you can fuck something up that can cost lives (aviation, bridges, buildings, etc...), you should have a license. Screwing up some code or mixing industrial chemicals normally doesn't fall into that category, though. If it does then yes you should be licensed.
This debate unfortunately lends itself to the Fallacy of the Single Cause [1]. I think this article goes a long way to implicitly argue for a multi-cause reason for the problem of uneven GDP distribution.

The global economy is a complex dynamic system, and doesn't lend itself to accurate modeling. So finding cause and effect is an impossible game - especially a single one.

We discovered that we were more efficient if we divided labor.

There was a short supply of people able to do some labor, but demand was high, so wages were high.

We've succeeded at that so wildly, and automated so much of our lives, that we have bountiful free time to train to be successful in modern jobs.

...while there is some specialization in modern jobs, there's a lot of jobs that are NOT THAT SPECIAL. So the pool of people who would be capable of doing them with no or a small amount of training is HUGE.

So wages are low.

There's no magic here, folks.

Meanwhile, Capital has chased not just profits, but OWNERSHIP of profit-generating entities. Rents, right? And they've been wildly successful at it.
Your argument just tells me you need a ped bridge, not slower speed limits. Even as it is, bikes are traffic, and drivers can wait. The differential is not the root issue in your case.

New developer looking to help
Hello I am a new developer and I want to help for example foodbank, gov, school with code and build my experience(not github).
I agree that driving on a German highway is a stressful experience. Especially since there is not so many highways with more than 2 lanes, occasionally changing to 3 lanes.

On a highway with no speed limit and only 2 lanes, the difference between the right lane and the left lane is just so freaking huge, you are stressed out every time you need to pass a truck or slower car, and almost always see your random Ferrari / Maseratti / Porsche approaching at a fraction of second of the time you spend on the left lane.

I would advocate for no speed limit on highways with >= 3 lanes, but would put a limit of 140-150 on those with only 2.
That's your problem there! :D

Self driving cars are just hype that won't be any significant for another decade. You should forget about self driving cars.

Self driving waymo/uber cars around Tempe (the suburb where Arizona State University is) have become part of the landscape.

Uber has also done a really good job of using their self-driving cars for marketing. My partner and I have taken quite a few uber trips that we wouldn't have otherwise, just because we've wanted to try and get a ride in one of the self-drivers.

So far, no luck though.

Not completely opposite. Trying to stay healthy is probably a good thing. But tricking yourself psychologically into a hard working employee is as crazy as it gets. You are not supposed to feel happy for being an employee and making money for someone else, because you are not in control of your own life.
