WTF are you talking about? I can and do write code on my iOS and Mac devices and Mr Cook and his company provide the tools to do it.

That's because music doesn't usually use a 12 tone scale, it uses a heptatonic or pentatonic scale, and Western musical notation is pretty good at representing that.

A single piece may not, but taken as a whole body of work, dodecatonic scales are the norm in most music today. So rather than have to say "this 5-stave notation represents the key of E-flat in this particular case", a 6-stave representation would be key-agnostic. Not all note positions would be needed in a given piece, but all instruments could play the same piece in the same key from the same notation. The notation would be clearer due to the lower degree of visual "compression" and the lack of need to notate exceptions to sharps, flats and naturals indicated by the key. Makes total sense. But it will never happen, because reactionaries would object, as you did.

The "sound" of a badly encoded MP3 is already influencing the way people sing - it's almost as if they think those artefacts and unwanted harmonics are something that makes a voice a good singing voice, because that's what they hear when someone holds a long or high note. Bloody hateful.

You're right - music as a logical system is pretty much a mess. But that reflects both its long history and lack of understanding that went along with it for a very long time. A great series to watch if you're interested in that is Howard Goodall's "Big Bangs" which is very interesting and approachable even for non-musicians.

The idea of musical notes being a straightforward geometric series took an awful long time to be realised, because of the idea (set in train by Pythagoras) that musical intervals HAD TO BE simple integer ratios. Just like Pythag's blind-spot about irrational numbers such as root 2, he assumed that nature abhorred nasty fractions. That thinking influenced music for millennia, and people still think that equal temperament is a "compromise" because it's slightly off from whole number ratios - but who says it has to be? That's just trying to force it to fit an idealised model of nature that is an entirely human idea.

Musical notation is also barking mad in the light of a 12-tone scale. It would make much more sense if a stave had six lines, so every note in the scale had its own fixed place, instead of wandering all over the place because 12 doesn't divide into 5. It would do away with clefs, the need to notate keys by use of special sharps and flats, and generally make it much easier to learn and use. However, it'll never happen because those who read the existing notation think it's fine, and a change would be too disruptive.

Listen to "Jealous Guy" by John Lennon. Entirely pentatonic.

The premise is that things going extinct is universally bad

Says who? You realise that >99% of species that have ever lived are extinct? Of course it seems sad when a species goes extinct, especially as it's often because of unnecessary predation by humans (e.g. elephants, rhinos), so let's concentrate on stopping our own species being such arseholes. However, in general extinction is totally natural, and as in this (rare) case when it's not our fault at all, then let it be. I suspect that those Iguanas will be perfectly fine if we just leave it alone for a change.

If this is true, then in the long run it's good news for Mac users - it will spur Apple on to make OS X better. That's what competition is good for - just as Windows users are now reaping the rewards of greater Mac market share in having Windows get better.

I have never understood why Windows users wanted to "win" by having all competition sink without trace, nor Mac users for that matter. If there's only one game in town, why would anyone ever want to make it any better? Healthier for everyone if there are at least 2 viable systems, preferably 3 or 4.

What you're talking about is "productionization" - in other words making a prototype able to be manufactured. That sounds over-the-top for a hobbyist project, especially a one-off, but I think it's often worth doing for several reasons: those you state, i.e. for reliability, longevity, but also a) because it gives you some insight into what's needed to create a real product not just a hobby project, b) it adds greatly to the satisfaction you get from the finished article. If (b) isn't a consideration for you, then you're probably pursuing the wrong hobby, for the wrong reasons.

I have to agree with you - Eagle is downright obstructive. Maybe you can get used to it, plenty seem to, and that perhaps blinds them to how awkward it is for occasional, casual users. Even the dedicated Racal CAD minicomputer system we used in the 80s was a lot easier to use than Eagle, and that's saying something.

The Golden Age of popular music was 1955 - 1995. It's over. That's not to say that all modern music is rubbish, or that there won't be another equally phenomenal period in future, but that particular seam has been mined out.

Pixels are a quantized version of whatever it is you want to portray. Pixel art is doing that quantization manually, when the computer could do it for you, rasterizing to whatever resolution it needs. Therefore the artwork should all be in vector form. They've been doing it that way for Fonts since the late 1980s, it's really about time all other graphics caught up.

The problem with LGW, STN and LTN is that they are not in London. Not even close. It's a bit of a joke that they even have the audacity to put London in their names. There are of course road and rail connections, but that just makes the journey more complicated and stressful.

Heathrow's "classic" terminals are dilapidated and badly laid out, requiring miles of walking through nasty corridors and passageways to and from the gates - the newer terminals are better but the entire airport is completely space constrained. In fact the whole south-east is completely space-constrained, so there's never going to be a new, fully functional London airport. Crossrail might make it more bearable, but the entire experience of flying in and out of Heathrow is a horrible nightmare. I haven't flown through La Guardia but I have through LAX many times, and that's the only airport worse than Heathrow in my opinion.

Any stable oscillator must have a negative feedback

If it's an oscillator, it must have positive feedback. That's what causes the oscillation. The oscillation itself may be stable, but that doesn't imply negative feedback.

Yes it is.

FTA: Alexanderplatz square

'Platz' means square. It's just Alexanderplatz.
