Two things have happened in this area recently.

1. The grams of rare earths required per watt of solar have been dropping steadily. And Solar PV panels with no rare earths at all have been developed, though they are not yet common.

2. "Rare earths" are not so rare. Their prices have tumbled substantially as new mines have opened up and substitutes have been found.
I am absolutely against that exam culture so I like that suggestion a lot. The exam perspective is just completely artificial which has nothing to do with the real world. That project based approach mirrors the real world much better where you can compensate for almost anything just by rising the effort one is putting into something.

>I have seen housewives and cookers heat the Teflon pan without oil for evaporating the water. Big no no with Teflon.

Oops... I regularly do this. Same question as previously.
It's difficult to say. Solar thermal is not dropping in cost the way that solar PV is. For now, at low penetrations, solar PV is a far better bet.

But solar thermal has the advantage of integrated storage. When solar overall is at some reasonably high penetration (say, 10-15%) storage will become important. At that point, it depends on the cost curve of storage technologies.

If batteries or other energy storage technologies have gotten cheap enough, PV + storage will be cheaper than solar thermal. If batteries haven't dropped in price enough, solar thermal may see a resurgence.

My bet is on PV + storage, though there is no certainty here.

This is pretty much how some of the better known standardized testing regimes work - SATs and the British O and A level exams.
"a random number generator determines the value of many of the prizes you encounter and the path some of the obstacles take."

Seemingly, you would still need several TAS-tries because of the RNG, right? (Unless you can rewind and the 'random' is calculated as a function of something separate from the running instance of the game.)
Like the government has the power or time to regulate the huge amounts of "chemicals"

How about instead of having "government" do the testing, we instead require that anyone creating a new chemical needs to test it for safety and publish the results (and raw data) before allowing it to be sold? Seems reasonable to me that you verify that whatever you're selling isn't dangerous (or if it turns out to be dangerous, inform the buyers so that they can act accordingly). Should be the same with any product too, not just chemicals.
Since the RSUs are a significant (ex: 90%) part of their equity portfolio, it makes a lot of sense to diversify here. (It's like founders selling 20% of their stake at IPO and buying an index ETF with the proceeds)

I think this would be different if an engineer went to work for GOOGL at age 35. At that point their assets would be diversified across various equity and/or real estate holdings and the GOOGL shares would represent a large but not overwhelming portion of their equity holdings within their greater portfolio of assets.
I think you are misunderstanding something. Shell scripts and unsigned code are treated exactly the same by Gatekeeper.

When you double click a shell script downloaded from the internet, the warning will not ask you if you want to open the file. The warning will tell you that you can't open it because it is from an unidentified developer.

Let me try to clarify this:
"Quarantine" is a flag set on files downloaded from the internet.
When you open a file with the quarantine flag, Gatekeeper checks the code signature. If it is valid, it asks you if you want to open this file that you downloaded from the web. If the code signature is not valid, or if the file has no code signature, you wont be able to open it.

There are several ways to execute shell scripts downloaded from the internet:
1) Check "Allow all Applications" in System Preferences
2) Right click, select open. Then the warning will have a second option to open it despite being unsigned
3) Execute it from the command line

All of these presumably require the user to know what they are doing...
The graph doesn't have an 2015 data on it, but the average in 2015 has dropped further.

I initially set out to model soft costs on their own, separate from module costs. However, that effort revealed other factors. Solar capacity factor is rising and operational costs (which are not included in soft costs are dropping. There are more variables at play. For some of those variables, there isn't robust data available over lon times.

All of those variables ultimately feed into electricity prices, in the end, which is why I chose that modeling approach.

> I'd rather pay more now for solar, than pay through the nose later for the environmental equivalent of a triple bypass surgery.

That's really generous, however I think it would be the government's duty to compensate for these externalities so you don't have to pay more for solar (or not much more) than for the grid. Otherwise the environment will just stay a huge "tragedy of the commons".
It's definitely interesting to see how a driving service company alters behaviors. In Brazil, almost not a day goes by that Uber isn't in the news where it's common to read about taxi drivers threatening physical assault of Uber drivers, forcing passengers get out of an Uber and into a taxi, and most recently, kidnapping an Uber driver. In another instance, Rio taxis even went on 24h strike (obviously not too well thought out).
I tried the technical preview of IoT core and was underwhelmed. The mouse didn't even work! It jumped around erratically making it unusable.

My experience with Linux on the Pi is that it just works out of the box. Simple things that you need to install a driver for on Windows are plug and play on Linux [0].

I installed the desktop Windows 10 preview just to flash the SD card. Although I read in the Mag Pi [1] that there is a Python script [2] to convert the image to a normal format.

"Groovy" isn't mentioned even once on this page. Are the Gradle people embarrassed about their sole offering of Groovy for the build DSL? Because Maven uses XML, any programming language can sit on top and be used as a configuration DSL. https://github.com/takari/polyglot-maven not only offers Groovy, but also Clojure, Scala, and Ruby.
There's a more concrete, specific reason, than generic risk that you should consider and discount the stock price of the company you work for accordingly: it is less liquid for you relative to the market, because you cannot trade it in blackout periods. Lack of liquidity is a cost to you, therefore, if you work at Google, a share of GOOG should be less valuable to you than the market price (assuming you consider the current market price to be fair, which is a totally different matter).

Being in control of so much of your hardware of course some hardwired logic could be included e.g. in the keyboard matrix that would make some physical interaction necessary during firmware upgrades, but not require a hidden button.

Nevertheless, as long as such a button or switch is easily accessible, and not able to be covered by a seal, the system stays vulnerable to evil maids. And such a thing definitely wouldn't be the Apple Way™
> What the author ends up proposing, as usual, is basically RPC-over-JSON [because] "message content/transmission channel."...

No he's not. The RPC pattern is a tad more specific than "any pattern that separates message content from channel". Likewise, just because you put one or more "verbs" in your payload doesn't mean you're doing RPC.

An RPC system has a much more rigid message structure that represents a function call, which is automatically marshaled via concrete client and server methods. If you're just receiving a payload and calling one or more methods based on it's contents, you're not doing RPC and you're not even touching upon any of the problems of SOAP.

The actual problems with SOAP have very little to do with the fact that messages can be serialized or that there are verbs. Here are some of the problems with SOAP:

- XML is verbose, making transmission slower.
- SOAP is a huge, complicated type system compared to JSON.
- Mapping SOAP to a given language is difficult.
- Security concerns over automatic function marshaling.

Meanwhile, you can write a JSON parser in an afternoon and it's extremely simple idioms are relatively easy to relate to a given programming language.

Outsource or Maybe In-House? – Don't Outsource Developers
I started with BigCorp at age 33, after leaving academia with a phd and equity measured mostly in magic: the gathering cards. So, uh, yeah. Assets.

- (I don't actually own any M:TG cards, which I use here as a glamorous stand-in for my actual hoarde of obscure tabletop RPG's, bits of electronics that could one day be synthesizers, and books about representation theory.)
This is the EU approach (REACH: http://echa.europa.eu/regulations/reach ). It's pretty burdensome, and somewhat unevenly applied (lead has been phased out of solder, but not of batteries).

The "verify your product is not dangerous" has had strange effects, as people selling hand-knitted stuffed toys in tiny quantities have to work out how to handle CE marking requirements. This kind of regulation sets an effective minimum size on businesses.
That's a much fairer requirement (and it exists in some forms), but it has some issues

Some substances are not meant to be in contact with people. It would be even unethical/illegal to study the contact of certain substances with people. Short studies usually can't tell the long effects of substances.

Testing in animals also has some problems (cigarettes are safe for mice)

Longer exposures (in a factory environment) also cause more problems, and in the case of duPont they're not the first not the last to be involved in similar issues (of employee contamination)

Just to be clear, I'm not defending the company, but to think government can regulate all kind of new substances that appear everyday is just silly.
Sorry, I deleted my post when I re-read the story. Still, it's not clear that the levels in the products were enough to have harmful effects, the problem was really the lack of care handling it in the plant, and the unsafe disposal.
> Because of the politics

Precisely, but not because of the second-half of your sentence. From my experience the problem lies in the revolutionary governments not being voted out: what has typically happened is the governments continue to fight the revolutionary war (which has long-since ended) instead of trying to fix the problems that the oppression of the past created. In some instances the government and governmental systems also become completely fixated on, in complete truth, getting revenge - this is especially true in Zimbabwe and South Africa.

One specific example (which is a very touchy subject). South Africa currently lacks electrical power production capacity: homes and businesses can expect up to 8 hours of blackout per week. The electricity utility company made the government aware of this issue circa 2005, at which point the power grid was nearing capacity. This was (and continues to be) because little-to-no capacity upgrades occurred. Instead the government was focusing on ending apartheid: even though that era had ended. It is this kind of focus on the past (instead of the future) that is driving portions of the continent into the ground.

I don't think it's entirely the fault of all of these governments either: they were born out of strife and it's natural that they would continue to cause strife. What should have happened is them being voted out: the problem there is that (due to apartheid and colonization) people were not educated enough to realize the change that needed to occur. The particularly villainous governments, being power hungry and revengeful, would also bribe the impoverished (with food) to vote for them or outright use violence and fear (Zimbabwe). Education remains a sorry story and it's thought that this is purposeful. In South Africa there is some hope, as I do believe Madiba did as much as he could to educate the people. This completely ceased when he stepped down, though. South Africa had so much potential during his reign.

A smaller, but still significant issue, is that Africa is being looted by the rest of the world. E.g. Anglo-Platinum: South Africa exports raw platinum only to re-import the refined product at a higher price. Building our own refineries is a blue sky dream because Anglo-Platinum would pull out, and, we don't have enough electricity to run such facilities. Many of our raw materials share this fate.

Keep in mind that this is not a universal result in Africa. I hear that Botswana is doing pretty well. This an opinion after living here for 28 years - so I may be somewhat jaded (although you may still find an insider opinion interesting), the truth may be out of grasp for many of us. I can agree with much of what is said in the article. Most assuredly Africa is a very complex place, which would lead to drastically varying opinions about it (especially for those living in it).

This looks good, nice work.

I need something like this at the moment, but I'm curious what the target company size is for a project like this. For example, we're a 2-3 person team and not quite big enough to have the capacity to run our own deployment of something as critical as Kala/job schedulers. Nor do I want to run another DB like Bolt/Redis when I'm already running another critical DB.

I'll probably go with a hosted solution ala http://www.iron.io/worker until we can run our own.
I'm very interested in feedback on the tutorial. It's under development and will be the basis of a lecture on the subject in next week.

Not really, especially in East European countries where the legal system is weak. When everybody hacks everybody every day and nobody gets sued then you stop to worry about hiding.
No single company, nor even ecosystem can 'solve' it. OEMs keep pushing new devices, with their own legacy stuff on those, likely we aren't seeing fragmentation be solved anytime soon.
Can you elaborate on this for me, I found the article confusing in its usage of C8 and Teflon (which seemed interchangeable as written?). What chemicals are used to produce Teflon which are harmful?
There are probably hundred ways to do it legally. Would you be surprised to find out that for every company with such a business model that gets caught there are 10 or 100 or maybe 1000 that do the same thing but more smart and therefore with legal protection? Wouldn't shock me.

Are you referring to student debt vs starting salary with your net worth comment? Otherwise I'd love to know where the average student is graduating college with such healthy investment portfolios.
I do this on cast iron. Never on Teflon.

You can use an oven thermocouple to measure the temp of your pan as you heat it without oil. If you do it once,and compare with the temps that are dangerous(you could see it on Internet) you will never do it again, as you will realize how fast temp goes up and how easy is to manufacture C8 with your pan.

Water acts as a limit of temperature, when it is wet it can't go higher than 100 Celsius(locally, it can in the parts of the pan that are dry). But once all water is gone, it goes hot incredibly fast. Oil does the same but with higher temperature than water, with way higher boiling pressure.

If someone does this mistake in one of my Teflon pans, I just throw it away. I never trust pans that are not mine.

Obviously, when you see smoke in the oil it is not good either.

By the way most of my pans are ceramic or cast iron.

The UK system (at least when I was doing it) at GCSE (14-16) and A-level (16-18) consists of smaller module exams, but students are allowed to retake the exams each time they're administered. So if they do well, it takes the pressure off their future exams, but it's not the end of the world if they don't. (EDIT: They're also standardised, which is pretty much necessary for this to work.)

I think it's a good balance between the massive short-term stress of big exams, and the consistent stress of smaller exams.
This is a very open question... you won't get much use from the responses unless you specify what it is you're trying to establish.

Are you interested in getting into programming but want to know which one will earn you the most money? Again, that's not a straight forward question.

Programming comes in tons of different forms... e.g. Desktop apps, mobile apps, games, simulations, algorithms, data manipulation, data analysis etc etc.

I would advise that you pickup a decent entry level programming language like C# or Java. Once you know the fundamentals you will quite easily be able to transfer your skills to other languages...

Don't pick a language "because it makes the most money".

On a related note, but not strictly in response to your question, there is a high demand for software developers currently and I foresee this continuing for a long time. It is a great industry to be in if you are concerned about job security.

Hope this helps...
Studies have shown that overweight people don't necessarily eat more calories or have less active lifestyles than their normal weight peers [1][2][3][4].

These appear to be observational studies based on self reporting. There are multiple studies that showed overweight people underreporting their caloric intake by up to 50%. Interestingly, people with normal and less than normal weight ofter overestimate their caloric intake, such as [1].

There are enough clinically controlled studies done that prove that caloric intake is the primary determinant of weight.

Thanks, I'll look into it. Right now the Android boxes we're using cost €50 (less if you buy in bulk) and do both accelerated rendering and HLS video, but I'm always looking out for more options.
The more interesting question I think is not whether skipping breakfast might help lose weight, it is whether the weight loss is due to lower overall caloric intake

It is overall caloric intake. This link [1] has 20 studies cited that support this hypothesis. At the same time, I'm not aware of any clinically controlled studies that contradict this hypothesis.

The doubt always comes from the studies where caloric intake is assessed by questionnaires and self reporting, which in turn was shown to be very inaccurate, i.e. [2].

While teflon pans are the most famous household use of teflon, they don't appear to be a significant route for these compounds getting into human bodies [1]. The main route is environmental contamination of crops and sources of drinking water, not contamination during cooking or household storage. The main sources of the environmental contamination seem to be industrial discharges, and the use of firefighting foams that contain PFOA/PFOS.

One of our goals with the Nylas calendar APIs was to make them backwards compatible, so that developers could still interact with Gcal/Exchange.
