Sapiens by Yuval Noah Harari. It gave me a good understanding of where we, as a species, came from. What did we do, why did we spread across the planet, how did we replace other hominids? What I really appreciated was his ability to explain some of the underpinnings of society like religion, nation states and currency with a relatively simple idea. Afterwards I felt like "damn that's so simple, I should have thought of that!" When you think that, you know you're on to something good.

On Writing by Stephen King. This a biography masquerading as a book on writing advice... Or its the other way around. Whichever it is, I think it's a great book for any aspiring writer to read. King explains the basics on how to get started, how to persevere and through his experiences, how not to handle success. Full of honesty and simple, effective advice.

Chasing the Scream by Johann Hari. Most people agree that the War on Drugs is lost and has been lost for decades now. But why did we fight it in the first place? Why do some continue to believe it's the correct approach? How has it distorted outcomes in society and how can we recognise and prevent such grotesque policies in the future? This book offers some of those answers.

Only if you're Indian - India After Gandhi by Ramachandra Guha. Sadly almost every Indian I've met isn't well informed about anything that happened in India after 1947, the year India became independent. History stops there because that's the final page of high school history textbooks. An uninformed electorate leads to uninformed policy, like "encouraging" the use of a single language throughout the country. If I were dictator, I'd require every Indian to read this book.

"People in Bakersfield aren't going to take the HSR to LA, at least not in enough numbers to justify connecting Bakersfield"

This is a pretty vague and evidence-free claim!

Note that thousands of people commute from Bakersfield to LA daily: http://www.bakersfield.com/news/residents-go-to-and-drive-gr.... The commute from the central valley to San Jose is also very heavy.

"take all the money you save and give a tax break to folks in Bakersfield"

I'd like to see HSR critics back up their claims with the ridership forecast model and public benefit accounting that you'd need to compute this tax break.
Back when my dad still worked at Aberdeen University, they had a phased array of maybe 7 or 8 transducers of about 8 cm each, that at a range of 6 inches or so, could deliver a focused beam that would penetrate a phantom / lab animal enough to cook a 2 - 3 cm sphere several cm below the skin.

The research was aimed at basically heating carcinomas above the 44 oC needed to kill the cells.

So you can focus an ultrasound beam, but it seems like a heck of a way to charge a phone.
People have been known to mistake them for volvariella volvacea or amanita brunnescens.

The article doesn't say how young the specimens these people ate were. Mushrooms that seem obvious as adults can be harder to identify when young.
The lower end BMWs are not fancy cars in the UK either. I don't know if they'd class as "cheaper" or "downmarket", but the typical example probably isn't exactly the opposite either. There are a lot of 3-/4-cylinder 1-4 series on the road, and the 520d is common too. Something similar applies to Mercedes and Audi as well.

(see, e.g., https://www.whatcar.com/news/the-10-most-popular-cars-in-the...)
Note: they make a claim that explains why you can't find a source for the transducer:
""In five years, we have invented five completely novel ultrasonic transducers," she says. "They are the world's smallest, thinnest and most powerful and potentially least expensive transducers that exist. This may seem novel now, but our mission is to have charging become a passive experience. It will fade into the background.”"
You're right, of course, but I think that if McDonalds let others use them, they'd have a good chance of becoming well-known within a generation, just like some of the old VCR icons are today due to use in myriad music players, video players, etc.

> Nobody was made to buy a home they couldn't afford. They wanted it

I suppose, in the same way that no one forces me to buy drinking water, I just want it, so as not to die.

If there is no affordable housing available (as is the case in most US markets today), you essentially are made to buy/rent an unaffordable home if at all possible. Because the alternative is homelessness, which isn't really an alternative.

Obviously, sometimes people purposely overspend on housing because of lifestyle inflation. But I don't think that's a majority -- many people are overspending on housing because housing is a fundamental human need and they have literally zero alternatives to overspending. It's more common than most people will admit.

I ask this as a totally naive person regarding novels and publishing, but who is fairly happy with writing papers in Latex: what is difficult about typesetting a novel? I ask because I would think that novels would be on the easier end of typesetting situations, but clearly your experience is different.. I just can't imagine what you are struggling with. I've "typeset" many novels by converting them from text formats to latex for the purpose of reading on my e-reader and haven't had many difficulties other than dealing with unsupported character encodings. Of course I can imagine that the professional situation is quite difficult, but I'm surprised it's so different. Care to share details of the trouble you had?
This is so USA. Anti science and individualism at its best. Surely if someone wants a thing to happen and works hard enough it will happen. This is cornerstone of USA belief. That science says it can not happen has zero perhaps less than zero bearing on it: it's just those leftist, hippie, commie professors claiming shit to put down a hard working woman.
> VCs, at leas the best ones, are there for your company in good times and bad. There is a difference, trust me.

This is backwards. Raising via an ICO mean no VC can ever push you out as CEO or take control of your company. Their priority is making the company get to a big exit, with or without you. When Ev was running Twitter, Fred wasn't a fan of his and had not problem plotting behind his back with Jack and eventually pushing him out.

Are we really in a situation where it's heretical to turn left when there's no traffic? Ok then.

If you didn't notice my other comment, we didn't see the sign. So maybe reserve judgement for whoever you like to judge.

The point of traffic laws are to mold behavior into healthy patterns, not to generate money for the city. That's the goal, anyway. If you're really defending a "don't turn left without an arrow under any circumstances," then I couldn't disagree more strongly with your stance.
I upvote many things that I already know of to let others become aware of them. It's a bit like xkcd #1053 [1], when I encourage others to read about something, they might then write comments about that thing offering new insights etc. that is of value to me. Additionally, them having become aware of that thing now might lead to them caring about that thing and doing something related to that thing that is of value to me in the future. But really my primary motivation is simply that I think that things I like deserve that I upvote them so that others can enjoy those things too regardless of future utility to me.

I would think a financial literacy exam would be too much.

I think a large red disclaimer page that says in very simple language: "This contract is unregulated and may be a dangerous financial transaction. Do not proceed unless you know what you are doing" that must be signed should be sufficient.

Simpler, tightly regulated contracts, wouldn't require this disclosure. If implemented well, it should be like the warning page you get when a certificate doesn't validate. Rare and scary is the best way to warn a consumer that something worth paying attention to is happening.
1. $400+ million to turn peanut fragments into a treatment. What?!?!?!

2. I think this treatment could potentially be a lot more deadly than the problem. It's a case of unintended side effects...in this case over-confidence vs. a strict no peanuts ever policy.

Imagine a kid has had the treatment and can eat 3 or 4 peanuts without a problem...a year or two later, maybe older & wanting to show off or over-confident, the child eats 12 peanuts...has an anaphylactic attack and dies. This case vs. a child who religiously avoids all peanuts, never considers them. A possible unintended effect related to psychology that I think should be considered.

3. Antibiotic use in infants and toddlers have been linked to a higher risk of allergies (maybe peanut allergies though I don't know if that's been studied & maybe that's why peanut allergies are a big problem in the US but not in India where most people don't take a lot of medicines)...try to avoid them if possible in small children though please listen to your doctor's advice. Antibiotics have some side effects which aren't great but on the whole have saved an incalculable number of lives.

Hey, you're the author, cool! Nice work.
Not OP, but read the book 'Hatching Twitter,' most of it is in there.
> Kilowatts in, watts out.

Probably milliwatts out, you have the conversion efficiency twice, once when you convert from electricity to ultrasound and then the reverse, where the reverse conversion gets the interference of the wave-fronts of all the sound waves emitted by all the transducers at the source all mixed up. It's not going to arrive as a nicely coherent wavefront.

That really is not going to help, and any losses to heating the air also need to be factored in.

Chances are the uBeam will end up pivoting to an ultrasonic heating system for coffeeshops.

Also, where do you see the 32x32 array?

Is it this pic?

https://www.gannett-cdn.com/-mm-/6e692618ead22efd1bb5f481476...

To me that shows a 10x10 array of much larger transducers.

The other device (the white ceiling tile) shows 7 hexagonal arrays each with 144 transducers, that works out to almost 32x32 for all 7 but they may be steering the beams to different phones from different arrays (they claim up to 5 phones) so it may be that only one such blade is active for a phone. And the total size of that array is much larger than 200 mm square.
I wrote a free tool a bit ago that wraps Pandoc/LaTeX/Jekyll and takes Markdown inputs and exports epub, mobi, and print-ready PDFs (5x8 & 6x9 Pdfx-1a compliant), specifically for fiction.

Have you seen the KOMA-script or memoir latex classes? They are very suited for typesetting books and have great documentation.
Getting otf fonts working, getting images working and properly positioned, getting alternating left-right headers to behave themselves, especially at a chapter start. Every new thing involved going back to ctan (I had high hopes for memoir) or searching online in the hopes that someone took the time to write down how they did it. Most of the time you'd just find "how to make your math formulas look pretty" or "how to typeset your thesis"

You'd think that typesetting a novel would be a gimme, but in the current ecosystem (tex or otherwise) it's a shambles.
> Moreover any vector z can be uniquely expresseed as p+q where p is in W and v is in symp(W)

Of course, crucially, this is only true if `W` is non-degenerate; as you'll know, one of the important things about symplectic spaces is the existence of half-dimensional, totally isotropic subspaces. (In fact, there's nothing particularly symplectic per se about this issue; it is not the (conjugate-)symmetry of the usual inner product so much as its positive definiteness that means that no such extra non-degeneracy condition must be imposed. Indeed, the study of non-positive definite but symmetric inner products, as in the geometry of relativistic spacetime, carries its own challenges to intuition.)
Never underestimate the ability of "very conservative" people, who hate tax-funded infrastructure, to nonetheless be heavy users of that infrastructure.

Remember, even Ayn Rand accepted payments from entitlement programs she hated.
Regular ultrasonic transducers are already very cheap when bought in small numbers ($2-$3), it would be very hard to improve significantly on that price-wise, the automotive industry uses these by the bucket for park assist systems.

This is hardly the first time I've been this deeply engrossed in a comment, only to pause half way through and think 'this has to be Animats'.

Thanks, John - I will never understand how you find the time to know everything.
You can actually buy commercial products that are powered by sound. Sound is actually a pretty great power source for wireless sensor nodes that monitor loud pieces of machinery. Sure, you don't get much power, but for a sensor node you don't need much either. Sometimes sound is the only source of power you can get for such things where it's too dark or parts need to move relative to each making wires difficult. Plus, sometimes you want to monitor the very same vibration that's giving your sensor power.

Now the thing that really gets me is some work I saw on developing a vibration powered sensor for highway bridges. So the best power source they found was a small wind turbine. But when they tried them out on a bridge out in the middle of nowhere, the problem was they were just too much of an entertaining object for people to shoot. So they made this rather large pipe with a magnet on springs inside and were able to harvest energy from the low frequency vibrations of the bridge moving around.

This type of consumer credit's also seems to exist to lure enough people other to other products of the cooperating bank. It doesn't need to be priced in into the product and could actually be paid for by the bank as lead generation.

Very powerful file renaming tool that also leverages TheTVDB, AniDB, TheMovieDB, etc for TV and movies. Both GUI and command-line versions available, I always use the (free) command-line version even though I paid for the GUI.

It also accepts scripts, has smart/fuzzy matching, and is an all-around good renaming tool for other things too.
I've been programming professionally for a decade and I've yet to see a "feature fairy" like you describe. I have seen a lot of crab mentality though -- mediocre developers and managers trying to use process to bring everyone back to the mean. Humoring the idea for a moment though: isn't anyone that writes a high volume of code also going to create a (proportional) high volume of bugs as collateral? If someone has written twice as much of a system as others on the team, it wouldnt be weird if they were responsible for twice as many bugs.

If this project makes financial sense, ideally an existing railroad company would run it.

Berkshire Hathaway (as the owners of the BNSF railroad) is the only US-based company that has the capital and railroad experience to even consider it.

In this situation, I'm not sure how or why the California government would turn away any foreign company willing to do it.

"Potentially" least expensive implies they're not the least expensive currently, but could be at scale.
When the rebuttal letter literally says "I am aware that there was significant controversy over SNCF in 2010, emanating from their role in deporting French Jews to death camps during WW II", I suspect the reasoning is more political bickering than anything else.

Even if the company did literally support the Nazis during the French occupation over 70 years ago, that's no reason to boycott them now.
There even was a company that tried to produce windpower based on that principle (windbelt).
Echoing the negative comments about this company. They interviewed me (two names ago, I believe it was Game Closure) via an engineering quiz. It took two hours and in the phone conversation that followed, it was clear they barely read my (completely working) solution, and then rejected my candidacy for vague reasons around the tech stack I used.
It's not a question of liberal versus conservative. The main value of HSR is allowing people to rapidly move between city centers for business or pleasure. How often do people in Bakersfield need to go to LA or SF?

Some people are born communicators and find interaction with others completely intuitive.

Others are born with a brain more ready to understand math, or writing screenplays, or software engineering, or business management - and bumble their way through communication, getting a lot wrong, not knowing where the lines are between their successes and failures, and generally having a miserable time.

Books like these define specific scopes to focus on as worth investing time and energy in, with the promise that understanding in these areas will definitely bring reward, as unintuitive as this may seem [to these people].

I wouldn't mind similar ones that explain learning how to learn, on a related note.
If you pump enough energy into the source, sure. But your average coffeeshop is not going to replace their ceilingtiles with what would be really inefficient space heaters in order to charge some phones (and cook the inhabitants in the process).

That's the whole point of the exercise here: if the efficiency isn't there the whole thing is dead because you can't be pumping kilowatts into space in order to get a few watts (or milliwatts) back out. The difference between the two will get converted into heat!

So the only way this will work is if the efficiency is really high, much higher than seems to be feasible right now.
Can you explain what's "vibrant" about the central valley? Their economy certainly is not.
Nobody here has the courage to respond. How could they when a bunch of cents on their drug dollar goes to fund the Zetas? Or the Taliban? The drug users here are too busy getting angry that the gov't wants to harsh their buzz to take an unsparing view of the consequences of their spending habits. You buy pot? Congrats, you paid a little bit to have some people boiled in acid. You buy heroin? Good for you, you just paid for part of an IED. You can wish it were different, but that's the reality of the market today.

New Jersey Considers “Right to Repair” Legislation
Yes, potentially anything could happen, but they don't know. What we do know is that mass manufactured transducers already exist and what they cost. uBeam is now developing custom transducers which normally would translate into a higher price rather than a lower one so if you don't mind I'd like to see that proven before I believe it given their history to date.

What something costs when you make it at scale you tend to find out when you make it at scale, and if they are going to revolutionize the transducer market that alone would be worth a fortune, never mind transmitting itty bits of power to cellphones.

Warcraft is nearly a pure meritocracy. I might not have very much when I start, but there is a clear path that I can take to level up. In short, Warcraft is fair.

It is exactly that dynamic of actually being predictably rewarded for hard work that people are finding in these games.

Redistribution schemes may seem just but they are very seldom anything approaching fair. Its no surprise that they almost never appear in any game mechanics.
