>Are supersonic aircraft more or less efficient

Surprisingly enough, supersonic planes have good fuel economy while supercruising - thanks to thin air at the high altitude, and speeds around Mach 2 ... 3 being good for turbojet engines.

Expect worse taxiing, take-off and climb fuel economy, due to dense air and also suboptimal (high) angle of attack. This means supersonic planes are best suited for longer routes.

Even the grandpa Concorde had good fuel economy in cruise, however it was overshadowed by atrocious fuel economy at low speeds, and the use of afterburners in transsonic region[1]. The designed but never built Concorde "B" would have notably better economy thanks to more advanced engines doing away with the afterburners.

Look, there are a ton of marketing submarines[1] on this topic, and there is precious little fact checking involved. I've worked on numerous wall street projects, I presently advise several HF startups; higher frequency and low, have consulted for a couple of fintech companies in the recent past, I've worked with advanced research teams at JPMC, Citi, Credit Suisse, a couple of big HF you've heard of and smaller ones you've never heard of. I regularly talk to one of the best regarded academic guys who attempts to apply DL to trading problems. I keep my ear to the ground as to the latest trends; people on the street talk to me because I'm a funny asshole and I know what I'm talking about. I have found zero evidence DL is being used in the financial services industry at all.

The reasons for this should be quite clear. It isn't appropriate for this kind of work. Pretty much all financial problems are insanely noisy, and DL is shit at dealing with any kind of noise, both in labeled, unlabeled and reinforcement configurations. Trading problems on short time horizons can harvest innovations vastly faster than DL can keep up using what amounts to Kalman filter like ideas. Long time horizons don't have enough data to fit a meaningful DL model even if 90% of the spectrum weren't noise. We're not talking something like automatic translation where you basically have all the clean data on the internet to fit to. The only place I could imagine it being used at the two-sigmas of the world is in natural language processing, but since you are asserting something completely different, that's irrelevant.

R&D departments, of course, fool around with it. And fintech companies are definitely implying they're using it because ... everyone else is. IRL they're all doing some kind of Markowitz MPT with factor models spooge. If you have any actual evidence that there is some large scale automation of wall street analysts facilitated by deep learning: I'd love to see it. Marketing submarines riding the DL hype chuckwagon are not evidence.

It bothers me to no end whenever I hear any leader describe the world in black and white terms like Aaronson does in this post:

>"I will seek to use this awesome responsibility to steer the ACM along the path of good rather than evil."

Even if this is partially in jest, it betrays the worst of "you are either with us or against us" kind of a mindset. A leader who thinks that they are on the side of good while the opposition is on the side of evil is incapable of reaching reasonable compromises. Such leaders are morally immature and fail at basic empathy needed to steer an organization that encompasses many people with diverse viewpoints and agendas. These leaders are prone to totalitarianism, trying to making everyone in their organization fall in line on the "side of good".
>Do you have personal experimental data to prove that eating handfuls of mud is likely to hurt your stomach?

I do have evidence that eating mud is likely to hurt my stomach: the relevant body of literature showing that this is a likely event for the population I'm part of.

In OP's case, however, considering that the relevant body of litetuare shows that placebos are very effective for improving sleep quality, I would say it's very reasonable to ask someone to elaborate on why they are so convinced that their method of treatment is not a placebo for sleep quality.

No one is saying they have to "prove" it--they can just elaborate on their conviction: perhaps OP had many insomnnia treatments before and this was the only one that showed efficiency. Not a proof, but it is some circumstatial evidence. On the other hand, maybe OP is not aware how effective placebos are, in which case his statement may be too strong to straight-out declare that "it's not a placebo effect."
How to Create an Alias in Linux
I don't think there's one right answer, but my opinion is:

- Treat APIs as immutable.

- Any mutation results in a wholly new API version, not a patch or minor update.

- The developer will learn what changed, and how much changed by reading the patchnotes, not looking at which semver numbers changed. This is probably a healthy practice to encourage.

- Don't change APIs so much. The interface should be very carefully designed and tested and shipped like an NES cartridge: consider it impossible to fix once its shipped.

Therefore just start with `1` and increment each time.

The reason I don't like semver is that it's a developer convenience that leads to sloppy practices. You built your product against a specific API. If the API changes, you need to re-run your entire API evaluation, testing, blessing workflow. If the delta is tiny (what would have been a patch change) then yay, your task is likely going to be very simple. But you shouldn't see a bump version update and decide you can cut corners.

That's an easy copout though.

Sure, commit messages could be mandated to be "whatever an individual, community, or organization decides they should be".

That doesn't mean any of those choices is optimal in absolute terms, or even optimal for the use case of the individual, community, or organization who made the decision.

So it makes sense then to debate what the optimal choice (either absolute, or per use case) is, and this is what the article tries to do.

It would be even better if we had some kind of objective, statistical check on such claims and their pros/cons (e.g. a massive test, with control groups, well defined procedures, and such).

But debating them is also a start, and is needed. If not for anything so that each "individual, community, or organisation" has some input on their decision, and don't just arbitrary impose a format for their commit messages.
Current laws make no distinction between the two. The State calls all prostitution 'sex trafficking'. So yes.. by the government's definition consenting adults is sex trafficking.
Large screens are more usable, small screens are more portable. There's no way to have both unless we completely rethink the mobile platform itself moving away from the dream of having one big clunky jack of all trades, but rather as a group of devices, all interconnected (mesh PAN + shared storage) and equipped with the hardware they need for the task, so that one small screen device is used as a phone, a bigger one to navigate, read bigger documents, watch movies etc, one even smaller one to shoot photos and videos, one to listen to music, record it etc.

But if you had picked any other tool from 2014, you'd probably also be stuck with a legacy code base now, without any clear transition path except a big bang rewrite. You would have probably picked angularjs or backbone back in 2014 and a switch to react would have been even more trouble. Meteor allows you to mix blaze & react, mix atmosphere & npm packages, mix their old module systems with commonjs and ES6 modules.

We made the same transition, but just replacing one package/ui part at a time when it suited us, so we always kept releasing new features each sprint while gradually modernizing our code base.

GP is simply incorrect here. Sanskrit dictionaries list multiple meanings per word sometimes with the period during which a meaning was prevalent.

If you are talking about things like PM10 or PM2.5, then it would be infeasible to re-add an identical or even plausibly equivalent pollutant, unless it's the one removed.

By definition, it is a concentration of things small and solid. Whether they are ground tires, engine soot, rock/dirt, pollen, mold spores or powdered cyanides, they are counted the same.

If you wish to replicate pollutants, then consider ethical implications of: Looks the same to me, my colleagues and everyone I know, yet it's not, or is it?

Feels like? On.. "the inside"? How's that going to work?

Don't you guys see the inherent problem in this? There is no "feeling" and there is no "inside". How such an illusion can come to be is totally unaccounted for and an ignored problem.

You write like some "awareness" is watching these machinations, but in your model there is no awareness, nothing is watching this. There are just a bunch of bouncing billiard balls. Where is the "feeling"? Where, exactly, is the "illusion"?

> I also note that there's not a single comment in this thread regarding rhymthic structure, again reflecting the western emphasis on a particular (simplistic) understanding rather than the highly developed music cultures built around rhythm across Africa and Asia.

This is so true. I've been wanting to learn about rhythmic theory for about as long as I've been studying music theory (harmony). But while you can find youtube videos and webpages full of explaining musical harmony all over the place, information about rhythmic theory is far and few between.

Most I've been able to find is either very abstract, like Euclidean Rhythms, which are interesting and weird but only explore equidistant grids (no swing). The other information is usually about really specific cultural rhythms. Both are good and useful, but I feel like they combine into less than 20% of the total theory about rhythm that I believe should be there. There's really a lot to it and I'm still looking for some fundamental theories about repetition and expectation and tension/release. The latter is very important in rhythm, but as far as I'm aware, the music theory about harmonic tension and release (chord progressions etc) seems so much more complete than what I've been able to find about rhythm.

If you got any good pointers, I'm all ears :)

> I think investing in air filters is a silly approach to this problem

The problem of air pollution and the problem of the fucked up society we live in are not identical in scope. You can't dismiss the solution to the smaller problem for not solving the larger one.

If living in a smog filled city is affecting my health, I will invest in air filters and masks before I invest in societal change that will change the way the world does business. I can do one in an afternoon, and the other is an unbounded task.

We should be able to tackle problems at large and in the small simultaneously, but your position strikes me as all or nothing in the sense that nothing but your exact prescription will do.

Given A: fucked up society, B: air pollution, C: depression, the world is probably a cyclical graph between all three. You are denying that B and C could be connected, just because you think A is such a huge problem. This is putting the blinders on against evidence for political reasons.

>> The end users have gotten used to AI-driven features like recommendations. Features like personalization can provide huge benefits for both the user and the business.

While it's true that "the end users have gotten used to AI-driven features like recommendations" most of the time the user is "used to" recommendations like Medieval peasants were "used to" poverty, wars and the Black Death. If I had a penny everytime I heard an "end user" making fun of e.g. Amazon's recommendation algorithm I'd be a penny billionaire (latest example: "everytime I order shoes on Amazon it shows me shoes for a week afterwads").

"Personalisation" in particular usually means personalised advertisement. I don't think at this point anyone can seriously deny that personalised advertisement is just personalised nuisance. It seems that only the people working in advertisement companies are immune to this observation. As a small bit of concrete evidence- well, that's why we have ad-blockers (and the success of ad-blockers, evidenced by attempts to er, block them, is evidence of the strength of feeling against internet advertisement, personalised or otherwise).

So, yes, personalised ads can provide "huge benefits" for businesses, as long as those businesses can profit while ignoring the annoyance those ads cause to the users. How the user benefits- that's another matter and I'm very skeptical of the article's claim that the user also reaps "huge benefits" by personalisation in this context.

Edit: just noticed the author of the article is participating in the thread. I hope the above doesn't come across as a criticism of the product itself. I'd be interested to know how the "predictive database" can help reduce the nuisance of targeted advertisement. For example, is the predictive database smarter than a typical recommender engine? Can it avoid situations like "I get shoe ads for a week afterwards"?

Sure, I think we actually mostly agree. My issue with SESTA/FOSTA is that if trafficking is truly the issue, it's far from clear to me that this was the right approach -- there have been credible pleas, including from law enforcement, that shutting down online solicitation would make it harder to fight actual trafficking because it drives it underground.

Meanwhile, SESTA/FOSTA effectively puts such a burden on web operators that even legitimate sites (like Craiglist personals) have been shut down out of fear that they will be liable if someone misuses them. This is even true in states and municipalities that choose to legalize prostitution. The effect of SESTA/FOSTA is to usurp states' ability to decide for themselves how they want to regulate the sex trade, at least as far as it comes to the communication platforms they can use. If the intent of SESTA/FOSTA was to inhibit prostitution that didn't involve trafficking, fine, but that's not how it was sold by elected Democrats.

I wouldn't be so cynical about this, except that there is a long history in the US of using moral panic around trafficking to enforce moral preferences -- look at how the Mann act was used against interracial couples, for example. I'm all for helping actual victims of trafficking, but using outrage about trafficking for other political purposes upsets me.
