About the collection. In general the photovoltaic technology efficiency is about 17%, commercially it's about 27% and there's technology reaching up to 45% but not commercially available.

There's another problem, the efficiency drops with temperature. I don't know what kind of heat dissipation this technology is capable of but assuming the worst case scenario the solar panels will surpass boiling point temperature. This means that without cooling the system in the solar peak it will have the worst efficiency by a huge margin. A typical solar panel is cooled by air, this possibly is siting in a heat insulator.

Another problem are the scratches. Ideally the glass need to be clear, but over time it will lose it's transparency so there is another mayor drop in the production.

There's another problem. As you can see in the video, using these roads you need to transport energy in or out. For do that you need wires, many, but they are expensive. Consider you don't use the energy generation... you still need wires to use the leds.

I consider more intelligent put photovoltaic cells in every building in the city. As you use the same power infrastructure you don't need to worry to install new wires. As the cities concentrate the use of energy then the lose of power due to heat (Joule Law) it's reduced. It's a plus in efficiency. As daily beings even if we don't save the energy collected (because batteries are expensive) is a win. We could use other energy sources during the night. There's another possibility, some scientist are trying to create a photovoltaic paint, this will be even more cheap but also less efficient.

Another ideas. Use the heat produced in thermal plants (Gas/carbon/Dissel). For example to heat the roadways or houses in cold areas (you will heat you house anyway). Use the heat for industries: smelters, oil refineries, glass makers among other. Remember the heat is a waste anyway, but is useful in many industries.

Use the sewer waste to produce biomass energy. Think about it, if your feces produce methane in your body before you poop... The idea is, in general the energy we use is carbon buried eons ago. Methane does not add carbon the the atmosphere only use carbon already there. Then add the previous idea and... imagine how much petroleum you can cut with this.
I think Swedish to English is pretty easy to do automatically to some satisfaction -- there are a lot of similarities in grammar and most words have direct translations. Chinese to English or Japanese to English with that level of clarity would be much more impressive.
Haven't tried those distros. (my distro hopping days are OVER)

Before Qiana, Nemo (Mint's forked Nautilus), Cinnamon's prefs panels, some 3rd party toolkits, they all got scrolling wrong. Lots of apps got it right too, but enough was wrong that the trackpad was pretty irritating to use.

Now, in Qiana, everything seems to work. (well, the physics aren't there, like flinging to scroll feels pretty dead, but it's not bad)

Based on that, I'd guess that Ubuntu Trusty would work great, likely Fedora 20 too. Guessing no for Debian stable or testing, but maybe unstable would be good.

Take solace, big corp won't let you change your wallpaper away from the approved one with the company logo, precisely so that no one is ever offended. That is the tradeoff.

Maybe the same thing that makes big corp so safe is also what makes it so boring that your friend wants to work in a startup instead.

Maybe startups have so much potential because you're opinionated but otherwise rule-free, so the tradeoff there is that not everybody is compatible with the company culture.

Maybe I'm a white Mormon, and there are millions of us in the USA (more of us than there are Indians, btw) who don't drink either despite the pervasive American drinking culture, and get pressured to drink. all. the. time. But get along better with an office of mostly Indian Muslims because none of us drink or send porno pictures to each other over email, entirely by choice rather than by regulation. And we can do it all in a tiny company with few rules because we have a company culture.

Maybe startup culture needs more Indian (or Mormon...) founders.

One of the pleasant takeaways from this is this entirely expected economic reaction to Amazon's behavior

"Amazon’s competitors are trying to seize the advantage. Walmart.com, for instance, is promoting Hachette titles at 40 percent off, and said Friday that its online book sales had jumped as a result."
The objective-c with ARC support really enjoys some advantages script programing languages enjoy. Apple added many syntax sugar such as `@[]` to build array and `@{}` to build dictionary, which makes it easy to write.

So I am not surprised someone is trying to use it as a so-called shell script. The cocoa frameworks really contains a lot of convenient API (ex. when it comes to python, you have to install PIL or something else to process images). But on the other hand the objective-c shell scripting can not be used on platform other than OSX. That is a disadvantage.
You talking to me? I never said I had the solution to the general problem. I only said that it doesn't seem like as big a problem as the Mint guys claim.

True, I did say that Ubuntu has solved this problem. For them, dist-upgrades are well understood and not blind luck. If you're disagreeing with that statement, I'd like to hear more.
Perhaps, over time, the increasing isolation of the US coupled with deep distrust of future presidents by the leaders of other governments may lead to a reduction in economic power?

Also, the impossibility of organising a broad based political movement for change within the US in response to, say, severely worsening economic or climatic conditions because of 'self censorship' by US citizens?

These are weak signals working over a long timescale. But those things are important.
I find both examples unethical. However, I never expressed an opinion on the unfairness of their prosecution. You argue a point that I never made. I don't think they should be treated like murders and neither should a GPL infraction. The degree of punishment is a different issue from whether or not I agree with what they're doing. I don't find that mishmash at all and if you do then that's your own problem.

You do have a unique opportunity to support TPB, though, as all of your books are available there. Maybe you should put your money where your mouth is and replace your amazon links in your profile with TPB links.
But either way, you're going to get a runtime error. Languages like Java or C# that actually have real interfaces and abstract classes can detect these problems at compile time. This seems only marginally better.
When there's a difference I find that ++x is usually what I need so I prefer to use it by default and x++ only when I need it.
I don't disagree, but will share a bit of my reasoning with you.

Two network ports. This takes the top of rack switch out of the picture in terms of failure zones. If you're using 64 port switches, having one drop dead is annoying in that it takes out a disproportionate share of the other resource.

Agreed that they don't have to be 10G, 1G minimum. There a funny story about the product guys at BigCorp saying 100MB was ok, and platform-networking folks arguing for GB. Needless to say the improvement when moving to GB was much better than 10x because the product guys were not thinking cross traffic loads clearly.

Storage distributed to the cloud is much much more effective than storage in a pod. Amazon is kindof figuring this out, Google figured it out about 10 years ago. Once you get to that point you realize you can push computation into the storage and that not only gives you resiliency in the face of module failure it make return from disaster faster (something the Joyent people might have a better appreciation for at this point).

32 full speed SATA ports give you 3,200 Magnetic IOP/s and 25,000 Silicon IOP/s. There are literally legion the number of things that you cannot do on one drive with at best 250 IOP/s and insufficient cache space.

Just a thought: terrorist networks may not be the most significant factor here. Recent outrages (and I mean that) in Boston, London[1] and Birmingham/West Midlands[2] UK have been the work of lone individuals who may have self-radicalised, 'consuming' propaganda thrown over the wall by terrorist organisations based in different parts of the world.

What exactly is the difference between 'forced' and 'pressured' in your mind? The two words are practically synonymous.

It doesn't matter whether they physically held her down and poured it into her throat, or that they cajoled her over an extended period into doing it. Either way, she was forced into drinking. Peer pressure is just another way of forcing people to do things they don't want to.

I'm Irish. I'm fully familiar with that kind of drinking culture.

Obviously that didn't work in this case.

$125? Amazon is showing me $209.

When mine wore out [1], I replaced it with the international edition. Exact same text, but paperback instead of hardback. Around $30 with shipping. Amusingly, I could either have bought from a dealer in India for around $10, with $20 shipping, or from a dealer in the US for around $25 with $5 shipping.

Good sources for international editions of textbooks are abebooks.com an biblio.com.

I strongly prefer to purchase items that are either sold directly from Amazon or "Fulfilled by Amazon" items if at all possible.

Among many many other differences, assuming your angle isn't to denigrate the Archive team, one of the important differences is that TPB makes no garantees about content availability. Information that you can find through TPB (they host magnet links, not content. magnet links can be used to find other who host content) is only available as long as those who are interested in the content are interested in hosting it. Conversely, the Archive people seek to ensure that content remains available even after everyone else seemingly loses interest in it.

It's something like the difference between your local used book store, and the Library of Congress. Or maybe the difference between the display cases of your local natural history museum, and the basement of the Smithsonian.
If you are looking for an alternative to Node check out Nimrod. If you just don't like nested callbacks in Node then check out ToffeeScript.

FYI Node is actually compiled so it might perform better than you think. Also it has threads with the module webworker-threads. Node is kind of memory hungry.

Nimrod lets you write clean Pythonish code that is as fast as C and even can interface extremely easily with C libraries if necessary.

Harvard University's endowment is the largest out of any university in the world. They have literally no incentive to squeeze matriculants, and have been increasing their financial aid pool whenever they can.

You really don't know what you're talking about. Harvard is trying as hard as it can to not be an elitist club. They regularly review admissions policies so as to avoid giving the appearance of favoritism towards alums.

They really are trying to be the best university in the world.

Technically it is not legal to do this. At that point, you're putting on a "public performance", and they may indeed sue you.

Where is the line at which "having a few friends over to watch the game" a public performance? It's up to the NFL's lawyers and the corrupt judges that decades of copyright cartel lobbyists have schmoozed.
20+ year C/C++ programmer here. I always use ++x unless the postfix version (x++) provides more succinct code.

The postfix operator can incur a temporary variable to be created by the compiler and thus make code slower.

Reading these stories it seems the rationale is "lazy bureaucrats". Clearly where this ends up is putting all poor people into a "system" which ultimate serves the blind will of the faceless bureaucrats running it. The pretext is that this power is used to "help" the poor, but ultimately it will be used simple to keep the faceless people in power--come hell or high-water.Iris scanning refugees is basically akin to iris scanning for food stamps.

I'm not 100% sure your point but if you release work under the GPL then yes, you are giving people explicit permission to copy and share your work under those conditions. But, to use that as an example, if you enjoy pirating music and movies then, to be consistent, I feel you should also support violating the terms of the GPL and all other licenses. In other words, you should not be upset when for-profit companies use GPL code and do not give back or comply with the GPL conditions. Because if you do feel that the idea of licenses and intellectual property are bullshit, then everyone should just be able to ignore them and do whatever they want. As long as someone can get their hands on the code then they should be able to do whatever they want with it.

I think that's a messed up attitude personally, but at least it is a consistent attitude towards intellectual property. I could respect somebody for being consistent in their attitude - especially if they themselves are also having their work pirated. Anybody who is pirating music and movies, but they themselves do not tolerate disobeying the license terms of their own work I feel is a hypocrite.

The timing of this post is impeccable. A very exhaustive new study came out showing that the value of a college degree is higher than ever.

http://www.nytimes.com/2014/05/27/upshot/is-college-worth-it...

Basically, you go to college in America or you risk being poor for the rest of the your life. Sure, some coders / entrepreneurs can do it without college. And maybe college is the selection process for these success traits. But with this size of differential on a very large sample size, I think its pretty hard to say, at least in earnings power, universities are not fulfilling the myth.
The killer gigabit app? It’s not what you think
Is it possible to indicate, in an interface, that it's not a structural type? Ie, that classes need to specifically indicate they implement it to be considered it's type?

For example, the HtmlString interface could require only "toString" as a method, but not everything that has that method should be considered that type.
Question from the uninitiated: in the 'old days', you'd write or expose a C library. Most languages support C APIs without too much work and you don't need to serialize/deserialize data structures.

Although the described approach has some advantages (a plugin is separate from the Neovim process, can run across a network, etc.), I wonder if in some situations this doesn't give to much overhead. E.g. if someone is scrolling fast, do you really want to communicate with all plugins over a named pipe or socket, doing messagepack serialization/deserialization?

Your 3%/yr is assuming you only invest in the safest of assets, like government bonds. You can get that up to 5-6% tax adjusted yield by having a bond portfolio (corporates, munis, junk, etc.) without much increase in default risk due to diversification. This would essentially cut your FU money in half, and going from 10M to 5M is a pretty huge jump.

If you have no plans of ever liquidating, you can use leverage (and increase your exposure to interest rates, which is irrelevant if you will not liquidate) but get up to a 8-9% tax adjusted yield right now, so then your FU money drops to about 2.5-3M.
Seems like it's more damage control than an actual expose. It's extremely confusing, why certain quotes were included unless they were to mislead the reader, e.g.

"It is not clear how many images the agency has acquired. The N.S.A. does not collect facial imagery through its bulk metadata collection programs, including that involving Americans’ domestic phone records, authorized under Section 215 of the Patriot Act, according to Ms. Vines."

Why would a phone metadata program, which is basically call records ever be thought to include photos?

No problem... I mostly remembered what I lost, it's just always kind of a wtf thing... I actually did send you guys an email, I think you'll know which one it is! Didn't mean to be overly critical, I was pretty happy with the experience otherwise.
Even a 5-6% tax-adjusted yield (which seems high, but I'm in Canada so I don't follow US rates too closely) is less than 5% after any inflation. Also corporate and municipal bonds are not without risk, although it's not large with proper diversification.

Parent implied the 20k/month was spending money. If you're reinvesting some of that money, then you're effectively reducing your withdrawal rate, in which case I agree. Also if you're willing to reduce your spending in the case of a downturn you could withstand a higher withdrawal rate. I'm just saying that a 5%+ real withdrawal rate is not sustainable indefinitely in a vacuum.
