Admittedly, there still a lot of room for solar panel research for the upcoming years which is pretty exciting!

The discrepancies is often due to fact we're defining "solar panels" quite different for each application and also the definition of input energy is different.

A great example is engines. The theoretical (Carnot) efficiency is limited by the heat difference between the source and the sink. You can burn fuel at a higher temperature and pressure which will give you great efficiency, but it's not realistically possibly due to physical constraints (usually the steel that houses the explosions). That's why steel engines are often said to have a maximum fuel efficiency of 37%.

This same idea applies to solar panel but it's even more convoluted. What is input energy? Is it all the energy from the sun or is it only the energy within the energy band that the panel can "see"? What is efficiency? The efficiency for different energy band is different for each solar panel as well. Worst of all, this efficiency changes for different temperature and is effected by hysteresis! By the time you store the energy, you also lose efficiency depending on the internal resistance of the energy storage (That's why MPPT exist and fun fact of the day, from what I know, there is still no reliable analytical method to account for this. Most MPPT trackers are done empirically).

Sorry for the long rant, but yeah, solar panels are confusing and there is a surprising about of research that still needs to be done!
Russian foreign minister proposes international convention on infosec/hacking
A 16 hour flight where there is a bed to sleep on in the plane would be better than a 6 hour flight crammed into a tiny seat like on a Concorde. Other than some 0.1%er stuff on really big jumbos you just don't see that. Where are the planes with the Fifth Element style sleeping bunks? I would be all over that if airlines could offer it at a reasonable price.
Well, marrying young for material benefits and being in love. I have no problem with gaming the system for benefits, because marriage is unfortunately tied to so many benefits.

Yes, when I was initially investigating it, it tripped me up which is why I wanted to make a point of it.

I know a lot of people on HN have far more experience with regexes at a theoretical level than me, so I'm also hoping any errors are quickly highlighted in comments here for me to correct :-D
If your argument is correct US and European slave trade in 19th and 20th century shows us what?
Wow. What a weak article. It basically tells nothing other than the fact that the Huns were people (we knew that) and that different people may lead different lives (we knew that also).
You have a really high belief in the ability of GPS to get things right. And probably of humans to work together when things aren't.

If you ask to be picked up at MacArthur BART station in Oakland and you're not careful, your driver will get routed to pick you up in the middle of the freeway that happens to run overhead. Some locations are also GPS distorting due to tall buildings and you'll literally show up 1-2 blocks away from your location (long blocks in SF's case). GPS is great, but it's not perfect.

Gee, it is almost like white people make up a huge part of the population. Apply a little Bayes Theorem and visit back when you've run the numbers.

Also, fwiw, Islam is not a race, hence you can't be racist for criticizing it. It is an ideological system. In that way it is no different than Democracy, Communism, Buddhism, Capitalism, Mormonism, Anarchism, etc, etc. Race doesn't define any of those ideologies either. In a free society we must be allowed to criticize ideas.

I'm allowed to criticize Islamism and its practices and beliefs. I'm also allowed to criticize Christianity, Judaism, Hinduism, Buddhism, et al. However only one of these ideologies regularly/commonly threatens to kill (and actually will kill) people who leave the faith. Only one of these ideologies has a large constituency who condones the intentional targeting of innocent civilians. It isn't a majority, but it isn't a fringe 1% either. Pew Research Surveys show the number to be 20-30% of these practitioners worldwide. (http://www.pewforum.org/2013/04/30/the-worlds-muslims-religi...)

I get to vote but, in democracy, we are a drop in the ocean.

In any case what's done is done, and if we've already waged war on them, it makes no sense to open our borders to them because most of them are bitter at us and some of them want to and have succeeded in killing us in our own soil. It's simply a security issue.

There are millions of Muslims now scattered everywhere in Europe, and these last attacks are simply the beginning. Now Erdogan can threaten us because he has a dormant army everywhere. And we let them in, like a trojan horse.

Exactly, 5 weeks! That's a huge amount by American standards. And many Dutch I know do take most that time in the summer, at once.
A few problems with scio:

- It's reading from (mostly) the surface, not the bulk mass. Not great for heterogeneous things like pills

- It uses machine learning models on 10-datapoint IR reflectance spectra, meaning it's only useful in a trained regime. It doesn't give information about composition, but instead classifies a sample as a member of a pretty constrained population. So a mystery substance that can't be roughly identified ('vegetable', 'pill' etc) can't be scanned, etc. If nobody's built a model for the thing you're scanning and for the property you want to evaluate, then you're out of luck

- So, evaluating drugs ("we can distinguish fake from real viagra") is done by looking at the surface coating which typically has no active ingredients (and even if there were, the signal would be washed out by inactive ingredients). The model is basically trained on 10-100 scans of a presumed good viagra pill, or maybe 10-100 different good viagra pills if they felt like it

- Building models requires purchase of a $250 license in addition to the $250 hardware, which is just ridiculous. Of course they're doing the calculations on their servers, but it still seems really scammy, hostile to developers, and counterproductive to launching an ecosystem of scanning models. The useless 10-point IR "spectra" notwithstanding, I would totally buy one of these if you could use open data and open models supported by a public community.
This again seems odd. Browsers shipped with Flash preinstalled, and EME in Firefox is a plugin.

People are just tying themselves in knots to act like the status quo is a disaster.
That's it, although I'd say it's access to capital & advice from wealthy people.

You can code and create a product anywhere; you can meet VCs by flying into SFO (VCs might fly to you if you are extremely successful already).
Interesting, though I fear if this becomes mainstream, the producers will just optimize food for good readings. Does that mean good food? I would bet not. It's the same as with roses which nowadays look beautiful, but smell like - nothing. Unless they put a drop of perfume on it (which they sometimes do).

This is exactly what pkg command on Solaris 11 does, though. The package manifests only are allowed to declare certain things: files, users, device drivers, and so forth. They are allowed to include service definitions as well, but services then don't need to touch anything outside of their designated area. On removal, no arbitrary code gets to run - pkg just removed the declared files, drivers, users and services.

Transitioning some packages took work and thought, but overall the system seemed pretty darn good to me.

Exactly. As I watch Downtown Brooklyn seemingly magically transform itself overnight from a collection of third-tier forgotten university offerings to a genuine nexus of tech and engineering education[0] I'm reminded that this dynamic does indeed work in both directions.

Houston is, for some definition of "tech". It's just more focused on petroleum and ocean engineering, which don't get a lot of play I'm these circles.
i didn't say any of those things. i said i had a small business. your favorite neighborhood restaurant probably does more revenues than my business, but it's still in the millions.

having a business with a single one million in revenues means you probably make < 100k in personal income and is the first to take a paycut when things turn south.

i see you're building a product. just wait until it starts making some money and you'll learn all of these things in due time.

Exactly right. Young people today would rather be poor in a "trendy" city, than rich in a not so trendy one. It has almost become a badge of honor of how much you can rough it to stay afloat in X trendy city. I am guessing it was not like this for previous generations, and I think it leads to too much homogeneity of culture. I think we should start to encouraging people to go to a uncool city and help build it up and make it cool.
Ride cancellation messages can easily have location attached and Uber can check if the cancellation location more or less matches requested arrival location. If they do not even send location - it's negligence. If they do send the location, but do not check it and still charge rider - it's malice. They have the tools.

Conspiracy theory: maybe showing that they actually have the tools could be unfavourable to them when/if the regulations are placed?
This is the web today. I stopped reading comments on most articles long ago because it's always like you described. This does nobody any good. Actually, it does politicians good to keep us separated down the middle. We are at our weakest in this position.

Uber's GPS and navigation data is such trash that this is halfway believable excuse. As a destination, Uber thinks I live halfway down the block on another street. It's not a convenience thing either. It's down a hill. It's flat out wrong. Lyft doesn't have this problem.

I have a friend who works at Uber on Second, and he says the same things happens to Uber at their own office. It sends the drivers to the wrong alley.

Conclusion? Bad data and drivers who don't know where they are actually going equals a bad experience.
Well, it's not the same as a simple positive or negative look-ahead, but that's not what I proposed either.

It seems riskier to employees if that were the case - if you get laid off or tired of one company in one of these small regional centers and there's only say 5 companies total to choose from, chances are you'll have to uproot your life and move to a new city for your next job which is a big inconvenience.

I think some part of the network effect of big tech hubs is the option value. If you're in the Bay Area you can have the best of both worlds - stay in one place as long as you want for your personal life/family, and still have the possibility of working at any of thousands of the best companies of all sizes and switching between them if you need to.
It's not an unreasonable legend. Conventional wisdom is that all Indo-Europeans sprang from the steppes of Central Asia. Having it mentioned in a 14th century declaration is pretty fascinating!
Speaking for London, the only taxis that you can hail are "black cabs" which are very heavily regulated (and generally high quality), but 2-3x the price of an uberX. You can book a taxi from a local taxi company, but that's typically over the phone, and ideally needs to be done in advance, they are often ~1.5x the price of an uberX.
Uber is sometimes cheaper and Uber drivers have an incentive to provide a better service because if they don't their rating goes down. Taxi drivers don't care because they don't have a rating and will be rude, overcharge or take longer routes than needed to make you pay more.
Typically 2/3rd of expenses in companies go into salaries. That's a huge chunk of money.

Somebody finds a system that reduces the salarial expenses to zero and all the hard-capitalists are over-joyed, secretly dreaming that they could apply this model to their own business.

In the mean time workers, while owning the means of production, are still liable to pay all the running expenses, to invest their time and work and give a percentage to a stranger, for some odd reason.

This is a form of feudalism.

I am not anti-capitalist, but I fear that this form of economy on the long run will not allow individuals to flourish economically through the merit of their work.
> Most jobs have completely unmeasurable contributions to the bottom line of the company (eg accounting, clerical, administrative, and such jobs). If you have a job like this, then get a hard skill such that your output can be measured directly. Learn to code, learn to sell, learn digital marketing lead generation, something.

Yeah bro! Forget your bachelor's degree in accounting, that has nothing to do with serious business. Serious business means one thing and one thing only: JavaScript.

> If you’re gonna be in $80k of debt you better be damn sure you’re learning a hard skill that can produce value for employers. This is something that’s simply not available in most colleges, so you’re gonna have to do research and find somewhere like Full Sail, General Assembly, or TechLaunch (my employer) where it’s actually possible to learn worthwhile things.

To summarize: don't waste your time with higher education. Spend your time learning to code, so that you can convince a person who wasted their time with higher education that you're worth keeping around.

Is there really an effective market in credit cards' willingness to refund? Aren't credit cards preferred mostly because regulation require them to refund the user in a lot of cases?

(Also, what's with that weird US regulation about a purchase having to be "within my home state or within 100 miles of my home" to be eligible for some credit card protections?)
I'd imagine, without putting much thought into it, that when you compare salaries, and then account for how much more is paid in taxes in (most) European countries, then at least parts of the comparison can get voided - like retirement savings or something of that nature.

If you're working as a professional in the US it's pretty rare that your health insurance isn't at least mostly paid for by your employer, if not completely paid for by them.

But like you said, that's why it's a tricky calculation.
All of which varies if you're single or married with children.

I'd imagine that for the young and healthy people without children, it isn't hard to sock away more in the US.
What happens when you miss giving notice to one of your contacts? What if your contact doesn't update their records right away? How do you get the timing just right? Not having your mail sent to a new address before you move in nor having any mail arrive after you've left your old address?

There is value in updating your address. Ideally, you won't need a year to get things sorted, but a couple of months is certainly valuable.

Carl Sagan was famously denied tenure at Harvard and membership in the National Academy of Sciences for his science advocacy. Different takes on it range from "jealousy" of his peers over his broader popularity to anger from them for his making science accessible and explaining concepts in a way that allowed readers to understand them:

https://en.wikipedia.org/wiki/Carl_Sagan

I used to see this with my peers in computer programming in the 1990s. There was a lot of anger and jealousy when everyday normal people started putting up websites. Several of my CS friends were of the opinion that this was almost polluting the WWW with bad code.
The challenges I see:

1. Vetting. Who vouches for the quality of each team?

2. Market making. Who insures that most teams find work and that most people looking for a team find one?

These are typical of two sided market places and harder for a narrowly targeted marketplace than for a broadly targeted one -- how different is a consulting team marketplace from Ebay?

The existing sites have not died because they solved the two problems and the ways in which they suck mostly reflect how they solved those problems, e.g. low rates solves the market maker problem so long as some consultants will work at those rates.

Good luck.

I agree that "tool" (in this case compiler) as a service is OK. You're also correct about "trust" aspect (that's what I've meant by "cloud" stuff).

Also In the FAQ on Kickstarter page it says that you'll be able to have your own "Nectar" server, so you don't depend on "Nectar" cloud.

But look at it seriously... 32k USD for a thing that will be probably faced with an open-source (and possibly free) solution.

Without a change in law, I don't see it. The owner or manufacturer of the machine is liable; they're subject to the law and prosecution. The machine could "suffer" the actions you describe, but that would be at most punishment against the owner, or more neutrally just removal of a hazard.

Guns and cars aren't prosecuted for murder. I'm assuming autonomous cars won't be either.
To be perfectly honest, cab service in some smaller places is horrendous. For example, do you meed to get to work by 9:00am tomorrow morning? You gotta call about 6:30-7:am. It might take them 15 minutes to pick you up or two hours and you cannot order in advance. There are no places to flag them down, so you always have to order one. Oddly enough, I've found these poor cabs mostly in places with no other public transportation. This sort of things plays games with a lifestyle. A trip to the GP can easily go from an hour-long short visit to taking up most of one's workday. In these places, I'd have welcomed the choice, even though I find it more risky than a cab.

That said, in places with good taxi service (where I*m at, for instance), there isn't a reason to switch.

Okay -- we played with this tonight -- and it's not fit for purpose.

There's a 5-minute delay, with a screen-on alert for the duration at the b-end, before you can get a geo-location response back.

If the 5-minute delay was configurable (I want it immediately), and the pop-up was a notification (sys-tray rather than full screen / break -screen saver) then it'd be a contender.

As it is, it's less useful than sending an SMS.
I was speaking with a friend about this recently. I do think we'll see growth in smaller cities, kind of like how Austin exploded. I think an interesting aspect of this is the job problem. Jobs are getting more scarce outside cities as industries change it seems, and I wonder how that might affect population movement.
The article explains that (?~foo) is not the same as (?!foo), since the latter fails the match if it matches, but the former succeeds if it can match anything that's not 'foo' (including 'oo'). The first examples anchor the patterns, so that this behaviour:

"foo" ~= /(?~foo)/ # => 1

isn't revealed.
Doesn't ubranization drive urbanization? I mean, people (myself included) treat living in cities as end in itself. People pay more of their income in rent just for the access and experience of urban life. So yeah, I think Cowen's justification is off.

There is a second layer where I agree with Cowen more, which is that urban cash flows need some 'engine'. People can only pay based on their salaries, and some fraction of spending in a city flows out (to food, industry, etc). So yeah, having a major economic driver raises your price cap, but it doesn't have to be creative. It just has to be something you can effectively do in a city and get money from elsewhere. I don't know what it would be for Tokyo, but in my home town it was urban-friendly manufacturing not creativity.
Yeah, I think there's either missing details regarding the attorneys, etc (which is possible) or this is really "How I Paid $30,000 for My Website." Either way the lack of customer protection from the host and registrar is appalling to me.
