This depends a lot on the cost of the model. For a powered model costing hundreds, or thousands of dollars, this is a wise addition because it protects the motor in the event of something going wrong (usually the control link dying)

However in RC gliders (slope especially) it's not necessary - the plane is made of foam and will bounce off any obstacle with minor damage, and they don't fly at long range. It's quite uncommon in this type of flying.

I've flown flying wing gliders that didn't have a flight controller - they work just fine. They're very aerobatic, though, which is less than ideal for carrying passengers.

The main issue I can see with this flying configuration is that the Centre of Gravity is extremely sensitive. You have quite a lot of leeway with a conventional airframe, but with a flying wing the CoG has to be spot-on or it becomes uncontrollable.
As you can tell by the reactions, HN is not Reddit. Perhaps make a post over there, they’re most likely more receptive to this story.
papers in top journals/conferences supervene everything but let's be realistic: if you're asking here you're probably not publishing in nature/annals/nips etc so unless there's something else exceptional about you (that you're publishing in mediocre journals as a high school student) LORs would carry more weight.

Publishing (public disclosure) starts a 1-year clock on patentability: https://en.wikipedia.org/wiki/Public_disclosure

In an effort that incrementally builds to something patentable, it would be difficult to find the perfect moment where the previous year's efforts amount to something meaningful and patentable.
Agreed. We can certainly engineer around climate changes.

About the only thing that might end us would be another asteroid impact of notable size. i.e. Indian Ocean 5k BC, Greenland 12.6k BC. Even then our current hunter-gatherers outside the immediate blast area and not near the coastlines would likely survive.
This filing makes it appear that Kik was attempting to scam investors. That is simply not true though. Take a look at the Kin Foundation’s github repos. This is one of the most active crypto projects there is. My company implemented Kin into our app with over 10 million users. 40 other apps have also implemented it. There are over 400,000 users spending Kin within our apps each month. Kik might have broken securities law in their offering to the public, but don’t confuse that with the resulting project also being fraudulent or a scam. It’s not.

>A lot of people see platforms like Twitter as inherently terrible

Good users can overcome deficiencies of a platform, but it's hard to deny that material conditions influence the level of discussion. Twitter always struck me as a platform delibrately designed to streamline low-effort shitposting and drama. Similarly, Reddit and (to a slightly lesser degree) HN are skewed towards circlejerking because of karma, while imageboards are conductive to thoughtless memeing and drive-by thread derailment, since there's hardly any downside to that when no one knows your posting history. Usenet was already dead/dying when I started to go online and I have no idea what went wrong there, I think that PhpBB fora weren't all that bad after all but that's probably just rose tinted glasses. I dreally wish there's some answer to building online communities besides "people are shit and when you bring N people together you get N^2 shit".

>However, I ask you to consider the most liberal and progressive figures of the 18th century

People change over time. My mother is over 80 now, and happily buys all kinds of stuff on Amazon with her laptop or smartphone, even though she said decades ago she didn't see the need for a computer. Her politics are also quite liberal, a lot more so than a lot of 20-somethings I talk to these days who seem to be a bunch of MAGA fans.

Also, how do you know that progressive people from the 18th century would have a problem talking to a divorced woman or women wearing pants? Just because that was the standard of the day doesn't mean that everyone from those times agreed with that.

>progressive people, and their opinions, turn into reactionary conservatives with nothing but the passage of time.

This simply isn't true at all. Many of today's conservatives are quite young, and lots of liberals are quite old. One of the most liberal SCOTUS justices is on her deathbed now, while the youngest one is a Trump appointee.
For a few weeks in 2016, my neighborhood was transformed by Pokemon Go. Children were everywhere. They roamed in twos and threes on every block; dozens gathered in the park. I couldn't believe that my neighborhood was home to so many kids. Then, as suddenly as they appeared, they were gone. I think if there were more reasons to be outdoors having fun with friends, children would find a way.

No, that's just your opinion, which other people are free to disagree with without being wrong. For instance, I find it perfectly acceptable that the story was initially published with ample reliability disclaimers, then later corrected when new information surfaced.

Me too. Mid 40's and trying to figure out how to make something stick, especially with stuff I had learned years ago (linear algebra especially).

I have recently come to the revelation that the notion of "rote" that I had always eschewed in favor of "a true and deep understanding" should no longer be so eschewed.

I've recently adopted Anki (that other people love so much on this forum) as a way of forcing me to catalog forevermore the inherent vocabulary of things that cannot stick without internalizing. I now have an Anki board for Rust, Linear Algebra and APL. Fingers crossed it will work.

Another meta-learning technique I have found extremely useful is creating an ontology map. The act of copying down a term and relating it to others spatially gives me so much more context. Here's a nasty one I did seven years ago: https://i.imgur.com/MYCsl7F.png

> Don’t non-EU students have to pay tuition fees? If not, they certainly should.

They pay "nothing" just like every other student in Germany. Nothing here means "less than 500 bucks of (administrative) fees / year". The added benefits that you get with being a student (for instance free public transport) generally already outweigh that fee though.

> No I don’t think an expensive university education is a “right” that these young people should be given for a chance in life.

Education is actually a recognized human right under the "International Covenant on Economic, Social and Cultural Rights" treaty. Exactly 169 Countries have signed and ratified the treaty, but the US are not one of them (signed but not ratified).

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

Because I believe in that right myself, I'll gladly pay for the education of every US American university student (and others) in Germany with my taxes until the US steps up its game. Curiously I'm paying for my own education that way too.

> I don’t think hosting 350k Chinese foreign students in US universities where 90% of them will return to China to compete against American companies and American jobs is something that the US should be doing on principle.

In total there are almost 400,000 international students enrolled in Germany. For free.

Nah, even that is extremely kind, unless you never see how your program is doing a few years later.

Usually you get feedback within 1/2 a year. That complicated search system with your own fantastic DSL an absolute nightmare to modify? Kind feedback. Your system works fine with 100 users but falls over with 10,000? Kind feedback. You used a trendy new js framework that disappeared 2 years later? Kind feedback.

And better still our industry has tons of people who write lots of books or do podcasts or do conferences where they talk about how their projects went wrong, and how they fixed them. Whether it was the GoF design patterns, or Code Complete or one of the many others.

To me, all of that is clearly kind feedback.

Could I get something cheaper if I spend time looking for it? Maybe, but the time I spend looking is also money down the drain, for what usually amounts to savings of a couple dollars and cents. Rarely worth it.

This is actually super simple to do in Cockroach, as it supports time travel queries - https://www.cockroachlabs.com/blog/time-travel-queries-selec...

So you can run a script at, say, 12:05 AM every morning, saving the table state “AS OF SYSTEM TIME 12:00” (simplifying syntax). And thereby get a fully consistent snapshot of all tables, as long as your backup script takes less time to execute than the configured table TTLs

Much better effect than some generic cgi animation could have had.

In hindsight that seems to be the case, but in 2017 at the time of the ICO, the laws and how the SEC would interpret them was much more uncertain. They clearly decided to take a huge risk and it backfired. I’m not saying that it’s a risk I would have ever taken myself though.

> Google has 90% of the search market.

To me this is not the biggest issue. The biggest problem is YouTube.

YouTube is a ravenous black hole that you can't keep content out of--and that is ALL Google's fault. If I put a video online and I don't want it on YouTube and it winds up there, YouTube should have to pay a sufficient fine in a timely enough fashion such that it won't happen again.

Instead, Google banks on the fact that the small guys would have to expend so much money to fight Google that it isn't worth it. That's behavior that the Robber Barons of the Gilded Age would be quite familiar with.
We need fewer people on bikes. When I moved to SF in 1999, I rode my beater single speed all around town in peace. Now I have to deal with rude people on bikes, people that don't know how to ride bikes on bikes, people that are on bikes that previously were jerks in cars and are jerks on bikes, people that are self-absorbed pedestrians on cell phones that have decided to try riding a bike in total oblivion to their surroundings....

Lets forget about protected bike lanes. Lets let Darwin's rule of evolution work for the responsible cyclists.
I've heard of this bug on and off for years now. Clearly it's not important to the Firefox team that Firefox is a viable browser on mac. Every other browser / application seems to be able to work around/with the issues described except them.
Good question. Here's the best summary I found. Note, it's an article from 2012. Search "facebook dual class stock structure" if you want to see much more that has been written on the topic.

"A string of voting arrangements outlined in Facebook’s SEC filing show that some of the company’s most powerful shareholders have ceded their voting rights to Zuckerberg, the company’s chief executive. While Zuckerberg only owns 28.2 percent of the Facebook’s shares, the additional “shares subject to voting proxy” gives him an additional 30.6 percent of the voting power, leaving him with a total of 56.9 percent of the shareholder voting power. That gives Zuckerberg full control of the company’s decisionmaking.

Under the arrangement, Dustin Moscovitz, Sean Parker, and a host of other Silicon Valley bigwigs have given Zuckerberg “irrevocable proxy” to control their votes. That means that their shares will swing with his shares.

Zuckerberg also has irrevocable control over shares held by DST, Greylock, Accel Partners, and other major firms and investors — and the voting rights that go along with those shares — in most circumstances.

“This is not common at all,” said Menlo Ventures partner Mark Siegel, who has monitored quite a few IPOs in his time in Silicon Valley and spoke to VentureBeat by phone today.

“He negotiated a very unique deal,” said Siegel of Zuckerberg’s coup. While no one knows exactly why Moscovitz, Parker, and a slew of high-powered VC firms would have given up their votes, Siegel speculated, “I’m sure there’s a point where shares were offered with that as a contingency.”"

They are looking for a test case because, per the SEC document, they were bankrupt and have literally no alternative but to fight it, as any settled penalty will sink their business.

They're so fucked. Good riddance.
I won't give them the benefit of the doubt on poor wording (they have plenty of time and resources to get it right).

As far as we know, there is no general ban on wearing instrumentation of any other on the job, unless it is somehow clumsy and would interfere with their duties or the appearance of their uniform.

In contrast, the simplest dosimeter is typically a very small patch of photographic paper in an envelope opaque to visual light but transparent to harder radiation (towards the gamma end of the spectrum). It is like an inch square, or like a typical nametag, easily worn in a shirt pocket, no more visible to anyone else than a credit card in the shirt pocket.

The only plausible reason to forbid this is to prevent any kind of whistleblower event.

Of course I do not know the actual levels of radiation inside each machine or all of their possible failure modes. However, we do know

1) high-energy radiation dosage is cumlulative -- each day's dose adds up, so if you have 1/100th of a critical dose each day in a workzone, in less than four months, you should be banned from that work zone. This is the way it works in many facilities dealing with radiation sources, and everyone wears dosimeters which are checked, and people are reassigned when the total dosage exceeds the prescribed level.

2) There are medical limits on how many x-ray and CT-Scan procedures are allowed for patients, again due to the cumulative nature of radiation exposure. Even with the very low-doses of modern machines, these are a concern and are tracked (I know this from the experiences of several close family members).

3) The TSA machines do produce sufficient radiation in their beam to fog ASA800 and higher film. This is definitely a non-trivial dose. Tho obviously not lethal in a single dose (e.g., if you rode through the machine), it is significant.
If an interior shielding panel is bent or somehow mis-installed during manufacturing, maintenance, or repair, it is entirely plausible that people working regularly in the area of the leaking radiation could be overexposed.

So, no, this is not even close to mere suspicion or Luddite "ooh radiation bad" -- and yes, we do know that these could be harmful, especially over extended periods.

I hope you are not an employer with that attitude.
