>Music I prefer, is usually also quite complex, but
"pieces so powerful they can bring people to tears."

... do really not need to be complex.

Sure, but that [that it needs to be complex] was never asserted here though.

The thread started from a comment made by tempguy9999 saying that they are bothered by the article saying: [the classical musicians] "who achieve such heights are capable of playing the most complex, technically difficult music on equally complex instruments that take decades to master".

And he added "Complexity just isn't of value in software and I don't know if it is in music".

My response to which was, and I quote: "Nobody said that music has to be complex to be good. But a good classical musician should be able to play the complex pieces too" and that: "You don't get to be a concert pianist or violinist if you only play the simple pieces...".

tempguy9999 further that they don't have the ability "to determine if there is any value in complex music other than coincidental. If you are a musician I'd appreciate your view."

To which I replied basically that many pieces (classical and otherwise) are both inherently complex and good, and gave some examples.

This whole thread revolves around its tail, but nobody said music has to be complex to be good.

What was said was, to recap:

A: Hmm, the article saying "you need to play complex difficult music on complex instruments that take decades to master" bothers me.

B: It says so for classical musicians. There are lots of difficult classical pieces, and to be a classical musician you need to be able to play them

A: But do they have to be complex? Or do they have just accidental complexity? Whaddaya think?

B: That's another question, but since you've asked, sure, there are classical (and rock, jazz, etc) pieces, that are difficult to play and highly technical, and are nonetheless masterpieces, and one would be hard pressed to take anything away from them. It's up to the artist how they want to express themselves, and a pieces can be very difficult/technical and equally beautiful.
PEGs are amazing precisely because they're as easy to use as, if not easier than, common regular expression syntax. PEGs are literally the same as regular expressions except 1) alternations are ordered, 2) zero-width assertions are formalized, and 3) quantifiers match greedily. This is effectively the same behavior as the Perl-compatible regular expressions with which most people are familiar.

Many PEG engines, especially for dynamic languages, permit grammar composition using first-class variables. That might be a small barrier to people more familiar with the terseness and conceptual simplicity of regular expressions as string'ish values. But it's fairly trivial to implement the latter using PEGs. For example, LPeg provides a small auxiliary module for doing that: http://www.inf.puc-rio.br/~roberto/lpeg/re.html

Also, Rosie seems amazing. I've not yet had the opportunity to make use of it, but I attended a presentation of Rosie by the author at a Lua workshop which left me very impressed.

But we already have identifying marks: license plates. What the paint job here does is make the car stand out, which is a different thing.
Is this a typo or total misunderstanding? In this article:, the author said "FAANG is Facebook, Apple, Amazon, "LinkedIn" (Wrong! it should be Netflix) and Google. ..." Frankly, if someone wants to give a "hiring (software developer) guide" but does not even know what FAANG is, I seriously doubt how good this guide could possibly be.
Some searching around on YouTube [1][2][3] reveals a bunch of cars on greek plates with mixed paintjobs, fancy designs, stickers etc. Some of those (especially 70s muscle cars) are stock from the factory, so perhaps there's an exception for that, a bunch of the rest are not stock. I don't know the situation in Greece, maybe you're wrong, maybe they re-paint them to pass inspection, bribe the cops, or the cops don't care etc...

I wonder whether automated mathematics software would really be able to compete with humans at explaining how areas of mathematics fit together and what roles different mathematical objects play.

I'm not a mathematician so sorry for the simplistic example, but for example, would automated mathematics software be able to do something like (a) invent the complex numbers (i.e. as an object in algebra -- a "field extension" of the reals), and (b) also make a statement like "these are useful for modeling cyclical/oscillatory behavior"?
Thanks for these, I appreciate the effort you put in.

I can't do them justice right now as it's late but I've had a quick listen, and will have a proper bash at them tomorrow.

But I'm beginning to doubt my original post; it asked if good music related to complex music. But if 'good' is so personal, my question becomes void because it's personal to each. (Edit: that was craply put, but I hope YSWIM)

If we want to define π×π, the best we can do is some kind of algorithm for generating an approximation to π (e.g. as a continued fraction or as a positional decimal fraction) to any desired degree, and then an algorithm for multiplying such approximations. We can prove some bounds on the error introduced by our multiplication algorithm, and that gives us a way of approximating the product to any desired precision.

For example if we want to know π^2 to about 3 decimal digits (~9.87), we can start by using an approximation of π to about 4 decimal places (~3.142) and then multiplying the two decimals.

For rational numbers, multiplication algorithms are usually built on breaking a number down into constituent pieces, multiplying every pair of pieces from the two multiplicands, and then adding up all of the partial products.

Matrix multiplication has the additional complication that the elementary terms involved (entries in different places in the matrix) cannot be added to each-other. But the basic procedure is still the same: break the two multiplicands down into basic units which we already know a multiplication table for, compute all of the partial products, then sum them up.
Considering how the only reason we don't ban cigarettes is that they are too entrenched in society and the economy there is a precedent.
I'm a cloud 1pass customer, but the UX leaves something to be desired, especially for a cloud app.

When adding an account to 1pass, it's important to click [save] before closing the tab, otherwise it's lost. (Having to pull passwords out of the PW generator history is a hack.) (It does support my belief/their claim that the pw decryption is done locally though.) To be fair, it used to be that you could accidentally click on the left pane and lose the unsaved account - they've fixed that in the latest of the 1PasswordX extension.

I haven't moved my entire life to 1password, so I don't have, eg, my passport or SSN or any outdoor license's in the system, and the inclusion of such things degrades my user experience - imo the new button should make a new login, with a button on that panel/page to change type, rather than making me pick which type of secret I'd like to create when I hit the [+].

I have, however, added my credit cards, but as far as UX, in the main UI, I click on the credit card category, then click on the search and try to search for a website login, only to have 0 results. Not surprising, I don't have an ycombinator credit card, but search results pane could surface hits in other categories if there are zero hits in the selected category - most (all?) of the data in 1 password is text, so I'm doubtful that full-text search is that expensive.

1PasswordX (the obvious chrome extension to install) doesn't work with TouchID without some extra configuring. (I set that for less technical people in my life, and that only came up after asking them why they stopped using 1pass.)

I'll give them a bit of pass on the difficulty of adding accounts on ios, but where many/most websites use email as username these days, maybe that could be autofilled when adding/creating logins manually?

And for my gripe about cloudification - I'm reasonably happy to pay a subscription (I currently pay for one, and am hopeful they're working on ^ UX issues), but every time I add something to 1pass, I question if adding secrets to a cloud/SaaS app, is going to royally fuck me over if AgileBits ever shuts down. Being able to save file-based backups to various places was reassuring. (Yes, this is a UX issue - it's not great if a customer questions if they want your product, each time they make the product more useful for themselves.) (See also: Trying to choose a Netflix title to watch, and giving up in disgust.)

TBC, I'm a (reasonably) happy customer, but I wouldn't hold up their UX as "well polished". I don't use it as a selling point when trying to convert people, certainly. At least I don't have to interact with it for the most part - I click into a password field, authenticate, and click autofill.

> At the absolute minimum, the B4UFLY app should not tell users that they’re “good to go” unless they are flying from an area where drone use is explicitly permitted, like national forests.

Even then... I thought I saw a sign asking people not to do that during wildfires so as not to interfere with firefighting operations. Do these things make it into some kind of temporary no-fly zone for drones?
Well I already have the machine and the electricity is free. That's the only reason though, haven't needed to mess around with AWS much.
No, you cannot.

Do the math on how much energy and resources would be required to do what you are suggesting at a global scale.

That’s the problem with all of these great sounding ideas, nobody bothers to quantify them —particularly at a planetary scale.

EDIT: Just noticed your comment about burning fuels.

I need to clarify something. And this is important. I have never --ever-- said (and I've written about this a few times on HN) that migrating away from fossil fuels is a bad idea. It's a great idea. We should do it to the extent possible. I've done my part, I installed a 13 kW solar power system at my home and we are on track to switch to 100% electric vehicles within, say, a year.

What is NOT OK is pretending that this is going to "save the planet". Our migration away from fossil fuels will do absolutely nothing of note --zero-- as far as reversing atmospheric CO2 accumulation. This has been studied and published. The conclusion was, to paraphrase, "even if we migrated the entire planet to the MOST OPTIMAL FORMS of renewable energy sources, atmospheric CO2 accumulation would continue to INCREASE EXPONENTIALLY".

In other words, even if we did the impossible (total migration to renewable sources at a global is likely impossible). Why? BECAUSE THE BASELINE IS 75,000 YEARS with NO HUMANS ON EARTH.

BTW, I am not yelling, using caps for emphasis.

We can discuss facts or that which we wish were facts. The difference is that we are never going to improve anything if we insist on ignoring reality.

It is OK to say "all of these proposals are nonsense", if, in fact, they are. It would be the same if politicians were proposing to save humanity by reducing the planet's gravitational constant by 10%. Ridiculous, but I bet someone out there could make a fictional case about the idea and collect an audience...just like the flat earth geniuses.
It's ok to abstain from voting if you don't feel confident about providing an estimate for SOME of the tasks. However if team members cannot provide any input on any of the stories then you have a bigger problem.

> usually results in a shrug

This is a problem. I'd suggest to repeat voting after having a conversation. And like I've said before - developers should try to commit themselves to deliver a chunk of work. It's hard to commit to random estimate that does not take your point of view into account.

You could also try replacing story points with t-shirt sizes. If you cannot agree whether the story is 2 or 4 points, maybe it would be easier to agree between M or L. I am not a big fan of this method but I've seen teams for whom it worked better than story points.
There is an entire class of first person flying micro drones called “CineWhoops” which combine first person real-time video and HD recording on the drone and have an AUW far under 250g. They are certainly a different flying and photography style from a DJI style photo rig, and I’d argue a much more fun one.
Just wanted to say thanks for replying with these links!
Maybe org-mode in Emacs? I know that can function as a spreadsheet of sorts, and I expect it probably gives you access to the full power of elisp. (I have minimal experience with using org-mode in this manner though.) This gets a bit further away from the everyman-programmer ideal embodied by Excel though.

I have been personally experimenting with user-extensible software backed by sqlite designed for organizing files by tags. I've found that given the right primitives, the right DSL, extending the program to create novel queries is a lot of fun and possibly even approachable for 'non-programmers'.

I'm saying that the inputs to the brain are data, and the outputs are data. The brain transforms that data in some way, and we have mathematical theorems that say yep, most of the ways data can be transformed can be expressed as an algorithm in any Turing-complete language.

If your argument is that the brain leaps past normal computation into hypercomputation or something like that, then you're making an extremely bold claim that doesn't match what we know about the physical universe (there is a long history of arguments about the physical possibility of hypercomputation, and most people don't think it's possible even in theory).

I know it sounds expansive to say that everything in the physical world (at least the bits accessible to our experimentation) can be modeled by an algorithm, but that really is the mainstream scientific view, and the edges where people argue about the fringe possibilities most definitely do not apply to the energy/time scales involved with the brain.
> A drone maliciously aimed at a helicopter's tail rotor could conceivably cause an accident

A gun maliciously fired at a helicopter's tail rotor could conceivably cause an accident. A laser fired maliciously into the eye of a helicopter pilot could etc etc. Do we ban any of those brought near a hospital out of fear that a malicious actor would use them in the worst possible way?

A malicious actor can always find a way to cause problems. A benign but stupid actor is the one we should be regulating for, and IMO keeping your drone 50 yards away from a helicopter landing pad should be sufficient.
That is a well worded, thoughtful and precise summary. Thanks.

And God knows how many other games and apps out there are happily running right now not knowing that some guy edited code directly on the server and left no trace of what he's done...
PE's 1.0 came out in November 2016. It's well and truly out of Early Access and has been for nearly two years and the playerbase had dwindled to a rounding error.

And even with Early Access, you're still paying for it as it is at the time of purchase--you're buying for the now or for the hope of the future, you are not buying for any future commitments of any sort. If this isn't well-understood already, it had best become understood, because financial exigencies don't really leave a lot of room for "but I bought it in Early Access!".

The finances of games are brutal and punishing and the race to the bottom that consumers have happily encouraged has resulted in those consumers' investment not being valued nearly as much. This was foreseeable and is inevitable. The best way to be reasonably assured that the games you like continue to be worked on, maintained, and managed is 1) pay a lot more for them up front, or 2) play games with ongoing subscription systems. As-is? It is economically non-viable to throw money after 30 concurrent users and nobody with a pocket calculator could fault them for it.

This is great
I don't know about "no privacy" when you can install (perhaps except for a few drivers, depending on which hardware you fancy) a FOSS environment.

I see where you are coming from and as a non-USA citizen I hate the Google integration as much as you probably do, but if this is the kind of thing you care about, Android is the free platform that gives you all the options. Those who say that iOS is more supportive of privacy... by default (if privacy is not important enough to you to follow a tutorial to install a clean OS), then sure, but when it really matters and you need to have control over your device, Apple just doesn't allow you to do that.

But let me repeat: I do see where you are coming from. Apple does a bunch more things right on this front than Android (again, speaking about manufacturers' defaults) and a lot of non-technical people would find it hard to even follow the step by step instructions that are available. I'm not sure there is an absolute right or wrong answer in the general case. I'm just saying that for the specific case of people that (need to) care about this, Android is at least an open platform with a (tiny, tiny) FOSS ecosystem.
It would be the same ammonia, but it wouldn't be releasing all that carbon in the atmosphere that natural gas brings when pulled to the surface.
True enough, but that isn’t going to solve anything.

The problem, again, is that when you actually look into the reality of such a proposal it crumbles very quickly.

Remember, the baseline is in the order of 75,000 years if humanity evaporates from the planet. Do anything LESS than that and it will take longer.
Ya, but someone who wants to down a helicopter with a drone isn't going to care about no-fly zones. The rules aren't meant to protect against the really evil people. They are to stop accidental collisions.

Getting a drone into a tail rotor would be very tricky. If the helo is in forward flight you would need a comparably fast drone to approach from the side, without being blown off course by the main rotor downwash. I doubt it possible. It might be done with the helo in a hover, but even there there would be only seconds of vulnerability. Say you get close enough, the tail rotor is itself another massive powerful fan. This wouldn't, couldn't, happen by accident.

The greater threat is pilots reacting badly to sighted drones. Fear of drones might well cause more accidents than actual collisions.

>> A trainee had been practising hovering about 15m (50ft) above trees ... Seeing a quadcopter flying towards them, the instructor had taken control. But he had clipped a tree with the tail rotor, causing the helicopter to crash to the ground and tip on to its side.

Wouldnt it be a really really long time to run out of oxygen?

“What would happen if we combusted every living cell on Earth?” it asked. That is, Peters wanted to know what would happen to the atmosphere if you burned down not just the Amazon, but every forest on Earth, every blade of grass, every moss and lichen-spackled patch of rock, all the flowers and bees, all the orchids and hummingbirds, all the phytoplankton, zooplankton, whales, starfish, bacteria, giraffes, hyraxes, coatimundis, oarfish, albatrosses, mushrooms, placozoans—all of it, besides the humans.

Peters pulled up the next slide. After this unthinkable planetary immolation, the concentration of oxygen in the atmosphere dropped from 20.9 percent to 20.4 percent. CO2 rose from 400 parts per million to 900—less, even, than it does in the worst-case scenarios for fossil-fuel emissions by 2100. By burning every living thing on Earth.

Philosophy is the study of knowledge, including the idea of "knowing", and furthermore even being in a position to know (existence). It is indeed more fundamental, as it was probably the discipline in which first useful breakthroughs were made in human thought. Though we would do well not to confuse being more fundamental, with being more important (as far as people & society today are concerned).

In a way, it is the fuzzy wiring that underlies most other disciplines, that you need to poke around in when you run into longstanding, or seemingly intractable problems in what you're trying to do above. See for example: https://news.ycombinator.com/item?id=20905801
