Sure, the spot price -that is: the wholesale price- for electricity in EU and AU might be negative, but that doesn't mean the end user pays less. Anecdote: the data centre I used to work in had a fixed kWh price for bulk electricity consumption. As far as I'm aware electricity retailers, at least in Australia, don't adjust their retail and bulk rates in accordance with the spot price. The retailers are about making money, not dispatching excess generation.

Also, very little oil is used to generate electricity. This Wikipedia article claims 5.5% of global electricity generation is from oil.[1]

Something I don't understand is why more coal and oil businesses aren't investing more in solar and wind. Perhaps they are and I'm not aware of it. Or perhaps they have a view of the market we're not privy to. BP used to manufacture solar panels, but they've wound down that operation.[2]

I'm generation source agnostic. I've read things that have made me doubt the long term viability of both solar PV and solar thermal.[3] I'm not at convinced burning coal is a good idea. Nuclear has it's problems, yet it does seem if Greenpeace got out of the way in Australia 40 years ago we could have nuclear like, say, France, and be producing one tenth the electricity related carbon emissions we do now in this country. I recently moved to Tasmania where electricity is 76%-ish hydro, but could have been higher if the Wilderness Society hadn't got in the way of the proposed Franklin River damn and hydro project, thereby halting indefinitely any new hydro electricity projects in this country. It strikes me as odd that the two strongest environmental NGOs in this country are now in a position where we can look back and, from a certain perspective, think 'Gee, that didn't really work out as intended did it.' So, ya know, I'm just confused about the whole mess. I'm fairly convinced, though, that if I keep clicking 'Like' the problem will eventually go away ;)

I agree with the parent comment that $10k is low for a bug of this severity. However, it's a step in the right direction that a non-trivial bounty was given, and it seems the person who found and reported the bug was satisfied with the reward. IIRC, Yahoo didn't offer monetary rewards at all until recently after the t-shirt scandal. I reported the first item duplication method I discovered in a very popular online game, and received a virtual pat on the back as a reward. I didn't even get a beta invite for a new game or expansion pack. I understand if a smaller company or open source game couldn't afford to pay a monetary bounty, but this company could definitely afford it.

I used the next dupe methods I found in that game and another more popular game by the same company to make money selling items to players. I should have reported all of the bugs instead of exploiting them regardless of the insulting lack of any bounty. We desperately needed money, and I gave in to temptation. I know that I was wrong, and hopefully my comment won't evoke responses that focus on my mistake alone. I certainly would've strongly considered reporting the bugs for a monetary bounty above $1k, the freedom to publicly explain the dupe method after the bug was patched, and a small acknowledgement from the company that I had found the bug.

Thought experiments about the most effective way to exploit a bug are a great way to discover places that flags should be set to trigger notifications of unusual activity in order to mitigate damage from exploitation. If the company that developed the game had put more effort into considering the question, "If a dupe method did exist in this game, what would be the most effective ways to profit from it?" then I wouldn't have been able to exploit the bugs for nearly ten years.
He means Ketones.

When you are eating excessive sugars and carbs like most people today, your body doesn't burn fat. You only use sugars for energy. That's why you have your energy levels constantly up and down.

I have been on ketagonic diet last 3 months. I eat no sugars and less than 50gr carbs. My energy levels are always stable now, lost 20lb. I don't need glucose for energy.

I see it as winter mode vs summer mode:

- If it's is summer there are sugars and carbs. So, your body keep storing as much fat as possible and uses carbs for energy and pushes you to eat as much as you can. Making you feel hungry all the time so you eat more and store more fat.

- if it is winter, there are nothing much to eat, so your body uses fat as energy.

The problem with modern world is that there are just so much food and carbs around us that we are always in summer mode.

I'm of the mind that we should be making an active effort to recruit coal miners into the renewable industry; there's a whole lot of wind turbines and solar capacity left to install, and those are much safer, healthy, and I'd argue better paying jobs that the coal industry.

I'm biased though, and think the coal industry should be starved of resources as quickly as possible.
Supersonic: New UI Hybrid Framework – Ionic, AngularJS, Cordova
All else being equal, you do want to minimize your input costs, labor, capital, raw materials, and otherwise, in whatever activities you're engaged in.

The fact that fossil fuels allow for a huge avoided cost (that of the prehistoric accumulation of sunlight and transformation into fuels) doesn't make low labor costs inherently bad.

I'm wrapping my head around various bits of the labor / wage equity question, but on balance I suspect it's largely independent of cost inputs to basic resources, including energy, which would mean that you're confounding two unrelated issues.

The goal should be to have sufficient accessible well-paying jobs. Not for them to necessarily be in low-productivity, but nonetheless essential, energy harvesting positions.

Though that may turn out to be the case.

QR codes seem ripe for disruption, but I am not sure Li-Fi would be the one to do so. Given an object that is illuminated, how would one know if it's Li-Fi enabled? If there needs to be a sign that says 'Li-fi here', might as well go with a QR code, or maybe better would be a more advanced image recognition technology.

I like the possibilities that come with Li-Fi, but it's a long ways from maturity.

There is no metabolic pathway that converts lipids to glucose. Your body will not be able to metabolize glucose from your diet if you're eating only fats.

The metabolic pathways which do produce glucose are:

1) Eat starches.

2) Eat protein.

Starches are converted directly to glucose. Protein can be converted to glucose by a process called gluconeogensis. This is what happens under either a starvation situation (in which case the protein is supplied from body tissues -- skeletal muscle and eventually organ tissue), or under a ketogenic diet, in which dietary protein could be utilized.

While dietary glucose is apparently not necessary, it's also not a bad thing, provided you're not getting excessive quantities or low-fiber sources which trigger an excessive insulin response.

That said: the typical Western diet provides more than ample glucose and starches, often in an overly refined form. That can trigger lipogenesis, in which excessive glucose is converted to lipids and stored as fat.

Gluconeogenesis (part of the starvation adaptation) occurs within minutes. Ketogenesis requires enzymes which take some time to be produced by the liver -- a few days, up to a week, for this to go into full effect so far as I understand.

And while the brain can run on ketone bodies (to a large extent), certain body tissues must have glucose, among them red blood cells.

Random tidbit, I lived a few hundred meters away from Marie Curie's place in my younger days (long after her death, in the 80's).
A friend of mine in fact lived at her place. One day, the city decided to have radiation studies done and everyone in the area got visits from scientists - they took ground and water samples at multiple locations.

Results were communicated later - and radium, radon levels were more elevated especially at the old Marie Curie's house. However, nothing had been done following these findings.

Several areas in the city with radium and other radioactive materials have been found (older and newer dumps really!). Some areas are blocked off with radioactive signs, some houses have been destroyed for safety now.

Both our families moved. Note that the house also is at chemin du radium in France.

My friend's family and mine have left a few years later. All that to say, even recently there was still very little awareness and safety precautions being taken.

You seem quite resourceful so you might enjoy MetaMath[1]. This is, in my opinion, literally learning mathematics from first principles. Well, it's not really learning mathematics (insofar that lot of the concepts won't be particularly novel), but it's really showing you the "first principles" of mathematics, and how you can build that up into other stuff.

If you feel like MetaMath is your kinda thing, do visit the FAQ; it's quite good (and virtually required reading if you're going to do this alone).

Admittedly, it's not going to give you the tools suited for solving problems of antenna designs, or enlighten you about electromagnetism, but if you're into just pure recreational mathematics, it's worth a look.

We were actually just discussing the "what if I trip their filter" concern at our morning meeting. Full disclosure: my company (as the username implies) builds FunCaptcha, a CAPTCHA alternative. Your concern, to us, is a very valid one and has been a driving force behind our own design and mentality. Our lead designer is (understandably) passionate about this so he actually wrote a few words on the blog that dives pretty deeply into the topic, if you're inclined: https://www.funcaptcha.co/2014/12/04/killing-the-captcha-wit....
I second this and would strongly advise this approach.

The courses available on Khan Academy help you visualize the math and gain a better understanding on the 'why' (reasoning) while also teaching you the 'how' (application).

There's sufficient math courses available to teach you everything from pre/primary school arithmetic to first year university/college level calculus/linear algebra.

>Sure, the spot price -that is: the wholesale price- for electricity in EU and AU might be negative, but that doesn't mean the end user pays less.

Nope, but it's a strong sign that they will do one day in the not too distant future when we have more intelligent grids (and more intelligent electricity consumption systems).

We are already starting to see this (e.g. the other day I saw a story about an aluminum smelter matching their production to the electricity spot price in Germany).

There are countries with power grids run by monopolistic assholes, often with strong financial interests in coal/gas/oil. Like America. The uptake of renewables in those countries will be much, much slower and they will pay more for electricity in the long run because they will keep the grids configured to operate poorly with renewables.

>Also, very little oil is used to generate electricity.

Yup, because it's damned expensive. This is why electric cars often end up being cheaper in the long run despite having higher purchasing prices.

This is also why solar panels are incredibly popular in Hawaii: their power stations do run on (expensive) oil.

>Something I don't understand is why more coal and oil businesses aren't investing more in solar and wind.

Typewriter companies didn't invest in computers. Kodak decided not to pursue digital cameras. This is the norm.

Large corporations are resistant to change at the best of times. They are ultra-resistant to change when the change will cannibalize an existing, profitable line of business.

Why is it difficult to understand code?
Probably that as you scale up the size linearly, the volume, and thus weight goes up as the cube, but the surface area goes up as the square.

Since this design relies on closing the circuit by having the magnets rub the wire, as you scale up you have an area in contact with the wire (surface area) going up as X^2, but the downforce due to gravity going up as X^3.

You could add wheels and metallic contact brushes to scale it up. Keep in mind copper is really expensive, and you'd be scaling that up nontrivially too, or the current would fry the wire (I'd think the mass of the copper would go up as the cube too, at least to accelerate at the same rate--acceleration depends on the mass since F=MA, and the mass of the train went up as the cube).
