> The ratio between fundamental frequencies theory is most easily debunked: if that were true, equal temperament tuning would sound unbearable, but the over-tone matching theory is not confirmed either thus far.

Strong disagree there. EDO results in pure 4ths and 5ths. And I’m not sure how you can separate ratio of fundamentals from overtone consonance. And I’m not sure how you can separate “pleasing” from culture/upbringing, or why anyone would ever think that you could. It’s immediately evident by different people having different tastes. I appreciate the research, but I don’t think any of this is at all surprising.

That some properties of “consonance” are shared between cultures seems unsurprising, too, since the sounds everyone is exposed to will follow the same underlying acoustic properties. You can’t form words without listening to the overtones above your fundamental frequency, and forming resonance creates a notable body experiences, so those ratios are going to play an important role in most cultures as a matter of course.

Alphabet wing needs to be at the forefront for creating policy that's serves both customers and businesses yet still avoids the swarm of nuisance, noise pollution, privacy violation, and operational failure. The only way to avoid public backlash.

Required are

1. Established routes

2. Operational failure protocols

3. Limits in Distance veering from established routes for deliveries

4. Collision avoidance

5. Noise to height ratio

6. Minimum and maximum speed requirements

7. Capability limits e.g. Video, audio, recording, delivery.

8. Color codes

9... What else.

>It weighs only around 154 pounds and makes around 110 horsepower—a pretty decent number considering how compact this thing is, and that includes everything: motor, single-speed transmission, cooling system, and power inverter.

Yeah, includes everything. Except, you know, for the battery.

It's pretty amusing how little attention the article gives for the actual batteries. The fact that you can easily swap out the engine will do so much when you still need to figure out where to cram an array of batteries smartly and safely.
These are excellent points, but I don't think this is as much a political thing as a personal one. The highly-numerate, low-social-skills set that makes up the bulk of the posters here tends to be disproportionately successful on standardized tests.

I think to a lot of us (and again, I actually agree on the policy angle here that testing is at best a flawed predictor of future success) this feels like a rejection of our own qualifications.
This is awesome. I want something 350hp+ I can drop into a truck. Compact cars cause back problems for the very tall among us.

HN threads are supposed to be conversations. In conversation one doesn't take a recording of what one said in a previous conversation and replay it. One makes a fresh statement of one's views, even if they're mostly the same as what one has thought in the past. That's part of how we relate to each other.

https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

Submissions and comments play different roles. Submissions provide topics for conversation. Once enough time has gone by—on HN, about a year—the cache is considered clear and the floor is open for a fresh conversation on that topic. https://news.ycombinator.com/newsfaq.html

> Please don't teach people how to self-censor.

You could say that about any rule that asks users to do one thing rather than another. I think most people here would support "please don't copy/paste into the threads" as serving the overall quality of the forum rather than seeing it as a censorship issue. This is the sort of case where it's probably good to have a rule, since the thing we want to avoid is having copy/pasting become common.

This is cute but stretches the point too far. Your time is better spent working in Inkscape versus handcrafting a file that is a hundred bytes smaller, more likely to have syntax errors and has to be tested across different browsers. Likewise, frameworks help standardize code and reduce a lot of cognitive overhead once you understand them and their limitations and workarounds. On the other hand, using white-space padding npm packages may be taking things too far.
You are absolutely right! Because heaviest part of an electric car is not the battery pack, am I right?

Why not? Markets are interested in capital gains and profit sharing, not necessarily steering the wheel directly.

How is it wrong for a founder to take a smaller cut of the profit in exchange for more power?

Founders (individuals) want a voice in their companies, and how much money does one need anyway? Investors (usually institutions) want to make money, and they need lots of it.

Seems like a fair trade.
Up front about coming from a left perspective. Pretty decent. Better than any mainstream paper in the US. I prefer the FT as far as UK newspapers go, but paywall.
Pre-fetching may be interesting if the first SQL query using prefetched data picks a small set of data stored on a disk plate here, then another one stored far away (distant cylinder), then back, then again far away, and so on... On a mechanical HDD the implied head movements may considerably slow this first query down.

Is there another case justifying a pre-fetching?

If I'm right pg_prewarm if not adequate with a SSD storage device, moreover "makes most sense if your database and your RAM are really really large" is sound as the amount of head moves is (typically) proportional to the DB size.

IMHO the most significant overall performance indicator here is the ratio R/D, where R is the size of the RAM available to PostgreSQL (mainly shared_buffers and the kernel buffercache), and D stands for the size of often used database objects (data, indices...).

Multiple runs of a benchmark in contexts where this ratio is 1, then 0.5, then 0.01... often produces interesting results.

No, it’s a terrible system that we have here in Ontario.

People kill themselves every year at Waterloo when they reach university and discover their 98% grade in high school math was a lie and they are completely unprepared and begin flunking out.

Simultaneously someone who goes to a good high school and learns real math but only gets an 80% (which should be good!) is instead stressing out that they won’t get into university because the published admissions average is 90%+. To their credit Waterloo actually adjusts grades based on which high school you go to, but now that is unfair to someone good who happens to go to a bad high school.

Finally you have rich kids that go from getting 60% in day school to getting 98% in their “accredited” private high school night classes which are economically incentivized to give the highest grades to their customers.

What a joke.
Yeah, I would discern personal bias from institutional distortion.

I can deal with biases because like you said I can sense truthfulness (good faith), and triangulate multiple sources to form an image by trusting my own bias. Bias and different perspectives are everywhere and carry valuable signals.

What I can’t sense is that I can check all sources to find what is actually true. His solution is to proxy our sense-making to some collective intelligence (community) grown in a positive-sum game. But our current game is zero-sum, and information becomes competitive rather than collaborative, which incents (guarantees) institutional distortion (e.g. obscuring, disinforming, context-shrinking).

Aside for describing the problem, I think he covers some practical ways to make sense of things in the broken information ecology, but I haven’t gone over that part in any detail yet.

So the DoJ has a criminal investigation ongoing. That's one thing.

But the airlines and the families of the victims of the two fatal crashes have standing to sue Boeing over this. This will take a long time to play out. The problem for Boeing here is that these civil suits will have an extensive discovery phase.

All they really need is an exchange like this and to follow the trail. Did a manager bury it? How high did these concerns go? Who was aware of this and signed off on having this system rely on a single sensor?

We're now at the point where single exchange that can be construed as a cover up will kill this plane.

It's absolutely shocking to me that Boeing has played so fast and loose with their reputation in a desperate attempt to compete with the A320neo.

So after all of this, how are we still at the stage this is "jeopardizing" the job of the CEO? Like he should be done. If the ever-ballooning CEO pay packets are justified by the shareholder value they create, doesn't the reverse apply? The CEO is responsible even if he was completely unaware of it because he failed to be aware of it, because he failed to create the culture and management structure that allowed this to happen.

The difference between this and a typical engine swap is that the car was never intended to be run this way. Are you planning on putting the batteries where the gas tank was? Will they fit? Will this have an adverse impact on vehicle dynamics? How are you going to manage charging these things? What happens if the battery pack ruptures? Is safety even a concern? Do you want regenerative braking? What sort of range is required? Does the fuel gauge show battery life or is it now useless? What about oil level gauge? Any other internal electronics? How are you going to drive an A/C compressor or is this no longer a concern either? Hydraulic/vacuum assist steering/brakes?

There are new problems to solve with this approach. It's certainly not going to be a straightforward process compared to a factory engine swap. There will probably be some body work involved. You will probably have to fabricate completely custom parts to get certain things to work together.

I don't see this as a reasonable solution for existing gasoline powered cars. It seems it's a much safer/cheaper/simpler/reliable option to purchase a vehicle designed from the ground up for an electric drivetrain and all of the nuances that go along with that.
> I haven’t found details about what sorts of battery packs it’s designed to work with, but ideally, it’ll be able to be adapted to work with battery packs from Leafs or Bolts or Teslas or whatever you can find in your local junkyards.
I am surprised more mechanics aren’t developing conversion kits for their customers. It would be a good way to deal with the impending decline of ICE maintenance requirements.

Plus you’d think it would really scratch the gear head itches a lot of mechanics have.

It would create demand for car bodies that were well built and easily serviceable. I guess I just wish things were very modular.
Some of the slides are contradictory: miss lack of safety by default and miss focus on GC.

It is well known and universally acknowledged that SAT scores are highly predictive of educational outcomes. See eg. https://collegereadiness.collegeboard.org/educators/higher-e... . You can use other alternative measures to predict educational success, but it’s important to get it right, otherwise you’ll end up with low quality student body that isn’t able to learn much and will drop out at high rates. Currently, high school GPA is also good at predicting success, but it’s highly variable among schools. Should SAT testing be abolished, parents who now pay for prepping will instead put their children in schools where they are guaranteed high GPAs.

With all of its flaws, standardized testing is still the best of all available alternatives for the purpose it’s used for. You need to acknowledge that no matter what approach you use, it will be gamed.Thus, if you want to ensure fairness, you need to choose one that’s hardest to game. Clearly, high school GPA, essays and volunteering is much easier to game than SAT score.

But the story is talking about "generational ownership" of companies, that pass control to heirs when the founder dies.

Whether through dual class shares, or retaining a large % stake, it's the same. The Ford heirs control Ford. The Walton heirs control Walmart. There are many, many companies in this world controlled by the children and grandchildren of the founder. That's never been a huge problem.

I just think this Techcrunch story is poorly written. It's acting "shocked" that a child or grandchild of a founder could still control a company. Nothing to be shocked about there.
>How accurate are their articles in general? Is it a publication worth supporting?

It's an opinion paper. Specifically, (UK's) Labor-style socialism + 4th wave feminism. If you have emotional attachment to those positions, you'll feel satisfaction and validation from reading it. Otherwise it feels like advanced clickbait, geared to give emotional validation to a particular segment of society.
Your lay explanation doesn't account for some important fundamentals - like the subtle distinctions between the different historic tunings, the fact that pure equal temperament is only really a thing on electronic instruments, the need for stretch tuning on some acoustic instruments but not others, the origins of the melodic minor, the harmonic minor, and the modes, the use of the dissonant major second in many folk musics around the world... and that's not even getting into the complications of composing in different styles.

It's not technically wrong to say that equal temperament is based on the 12th root of 2. But it's also not a complete description of real world tunings, especially in acoustic performance.

Generally, math turns out to be a bad way to understand music. There are elements in music that look like math, but the similarities turn out to be superficial and massively oversimplified. If you take them too literally you run into serious conceptual problems almost immediately.

In fact the defining feature of music is that it always slips through any simple bounded conceptual model. Music simply isn't simple. That's what makes it so interesting.

Notably, well-temperament is not equal-temperament. Also under-appreciated is that you can change the pitch of each strike of a key on a clavichord by striking harder/softer or pressing into the key. It uses a “hammer-on” like action, so if you press into the key after striking a note, you will increase the tension on the string and raise the pitch. For me, realizing this gave me a whole new appreciation for CPE Bach’s music. There’s probably a dissertation in that somewhere for somebody.

A klavier is not necessarily a clavichord, but an organ has some interesting tuning tricks up its sleeves with its various stops.
since you remove the fuel tank, the gearbox and the engine there are nice chunks of space. Someone should start working on modular battery packs that could be assembled to fit current space.

This is a hard cut over from Python2 to 3. This presupposes that both upstream and downstream deps are on Python3. On which magical day does everyone decide "to have their port finished" ?

If it is the same work to to support both 2 and 3 as jettison support for 2 in favor of three. Then supporting both so the system can actually upgrade is far preferable. Applications and libraries not used in isolation. To jettison support while the rest of the dependency graph is flux is analogous to gimbal lock, you can't just get here from there. Without `six` the whole Python ecosystem would have bifurcated and Python2 would still be the dominant Python.

I don't think the fuel tank and gearbox in my car take up that much space when compared to the batteries in a Leaf or a Tesla. And you still need to put this where the engine used to go, so it's really a limited amount of space there as well.
