Comment Don't be an idiot (like I was) - max-out on math! (Score 1) 656

Early 30s, undereducated, curmudgeonly, senior software developer here.

Not only is math my weakest area, but that weakness was probably partly due to my self-defeating and self-fulfilling belief that I didn't *need* much math, so I got my CS degree from a shitty university with just through Calc 2 and a couple non-calculus-based stats classes. No linear algebra, no dynamics, no quantum-anything, no Fourier analysis, no algebraic topology, no number theory, no discrete math, etc..

And so I've spent the last decade writing stupid CRUD-and-forms apps. It's boring shit that only pays high-5-figures (in my top-3-by-population U.S. city as I work in university research, though I am repeatedly sought by some of the biggest names among tech employers. But I choose my current employer for the work-life balance).

But to go anywhere more-interesting -- say, working on self-driving cars, or data-mining stocks or health data, or building robots -- I need more math. Shit.

I have taught myself some linear algebra from a LA book, at least, as well as learned some slightly less-basic stats (e.g. Markov models) and taken a couple graduate-level CS courses in AI and ML. But it's definitely not enough to break-free of my self-imposed intellectual chains.

So, get as much math as you can -- not because you'll definitely use it (maybe, maybe not), not because it's fun (but if it is for you, great; it is for me, when I understand it), and not because it's important for its own sake (by definition, anything that isn't eventually useful is useless), but because it gives you FLEXIBILITY later in life. And you have no way of knowing, a priori, whether you will need that flexibility.

I'm not original in this thinking. Learning more math is what Nassim Taleb would consider an example of "robustification" -- becoming robust against unknown undesirable future "bad" events or scenarios.

My strong advice: Don't be so damned efficient - or arrogant/overconfident - in your learning that you fail to robustify yourself against a future you that is smarter and wiser than the current you.

A "roadable helicopter" makes as much sense as a product as marketing bicycles to fish.

And a "flying car" that can only land at heliports might be great as an easy to fly helicopter, but it's utterly useless as a flying car. As a hint: If you can afford a helicopter and its running costs, I'm sure that the limo from the airport is small change for you.

BTW, in the UK ( so a heli pilot friend tells me ), in general you can land your helicopter anywhere where the landowner has given you permission.

Traffic jams are real, but putting the cars in the air isn't going to fix that problem. The key problem with driving cars into cities is that they take too much space per passenger (at rush hour, on average, 1.02). Granted, putting traffic corridors in the air gives you a bit more space, but you also need to leave a lot more safety margin.

Flying in a straight line might save fuel compared to flying detours, but that doesn't mean it saves fuel compared to driving. These flying cars don't stay in the air all by themselves, you know? And, seeing as we're all bitching about the price of gas to drive... ask your friendly helicopter pilot how many gallons his chopper burns per hour.

There are solutions to traffic jams. Telecommuting, walking, cycling, public transport.

Oh yeah, and if your hearing's still too good: Suggest to Air Traffic Control that they replace the couple of hundred planes / day over, say, LAX, with a couple of hundred thousand planes^H^H^H^H^H^H"Flying Cars" per day.

Don't get me wrong, I'd love to have a flying car. But frankly I'd rather save up for a one off trip to space instead. At least I won't have to kid myself that that's solving any problems.

The basic reason: it has no fixed value. It trades like a stock or commodity. In recent days it has been crashing after a spectacular rise in terms of dollars.

Has the man never heard of FX markets? Currencies trade exactly like stocks or commodities. They don't have a fixed value either.

She basically shut down the UK's manufacturing industry and moved us over to a service industry economy. Pity we're now outsourcing all the services. I remember living under her stiletto boot heels I'll not be dancing in the streets like some will be but I'll not miss her either.

She didn't kill British Industry; the Unions did that.

She just put it out of its misery.
