So far, all of the lawns on our street are yellow. My neighbor just dug up his lawn, re-landscaped the dirt, and plans to try grass again next year. My church got a polite note from a neighbor informing us that our sprinklers were sprinkling the sidewalks some of the time (glad they said something). I think all of us take more notice now when non-residential entities are overusing or possibly wasting water. We also use less bathwater at home for our kids and spend less time in the shower. It doesn't really feel so bad for us non-agricultural folks at this point.

I once met a retired government employee in the desert in Utah, and we talked a bit about water and droughts before he said, "things would have to get really, really, REALLY bad before you couldn't get tap water on demand anymore, even in a desert like this." Listening to his experience I realized that he had the benefit of some experience that I didn't. Not that it makes a draught feel any better. And the wildfires that make your city smell like a campground for days at a time don't help either. :-)
How do people from other countries attend the event? Do they send invitations, so I can get visa and be there? I'm crazy enough to travel 6506 miles to feel that experience.
A look at the specs: 419x138px monochrome green display.. so they basically attached a COG lcd display to glass frames? This actually doesn't seem to hard to hack with off the shelf components...
Quick Tutorial on setting up cheap and effective lighting for videos
I get the gist of what you are saying and agree with some of it. I still think the article isn't sufficient, at all, for even an elementary introduction to anything. It's incredibly incomplete. An introductory cs course is going to present asymptotic complexity analysis (written using Landau notation) as one of the TOOLS for thinking about the efficiency of code. It will hopefully not just hop to big O without setting up the context. The author can fix this by just reworking the preface. It needs to answer the question: "why are we doing this and how will this accomplish anything?"

If you fail to frame the context and the semantics well enough, you'll end up with people running around saying that an algorithm is "big O of blah." AGH

The introduction to the concept is articulated by the following comparison:

'We want to measure code efficiency. Big O notation describes this. Here are some examples.'

vs.

'We want to measure code efficiency. We can do this by thinking about its usage of resources (complexity). for example, total run time and memory usage. One of the ways to compare the efficiencies of algorithms is to compare their asymptotic behaviors. We can express this using big O notation. Here are some examples.'

-----

The author talks about how big O notation is awesome because you can drop the constants. It is not explained why this is awesome or useful. Interestingly, it later says that sometimes it isn't good because the constants sometimes matter. What is the reader supposed to understand here?

There's no followup as to what to think about after you determine the "big O" of an algorithm. Either he forgot to write this or figured that it was obvious at that point. Considering that he didn't sufficiently explain the concept's motivation either, I don't see how an uneducated reader will get a clear picture.
This reads like a grotesque Cass Sunstein-architected "nudge."
" if you fail in whatever you are doing because of a baby, you would fail without it either. "

Try and switch those two around:

if you fail in being a father because of whatever you are doing, you have failed having a child.
Because I didn't like his tone.
I'm a father. I have three teen-age children: 17, 15, 13. I'm a business owner.

I'm also a lawyer and I know what it takes to create and maintain an LLC. It's a big fucking pain in the ass, and it is totally irrelevant to the success or failure of a business.

Maybe you can't see the view from your father's side of the equation. Nor can I -- I do not know you and we have never met. But I can guess what is going through his head.

What I do know is that I deeply want my children to succeed in life. I'll bet your father does, too.

I'll also bet that he doesn't give two fucks about owning 50% of a company with you. I'll bet in his eyes the company is 100% yours, and he wants nothing but the best for you.

He didn't invest in a company to buy you a MacBook. He gave you a MacBook because he's your dad and he loves you and he wants you to massively succeed in ways he never did.

He's watching you work hard, and I'll bet he is thrilled at every achievement, big and small. He's probably thrilled just to see you get down and grind hard. Do you know how rare that is in a 16-year old? That is gold to a dad.

He was probably crushed when you gave him the MacBook back. Because that meant you were quitting. I hate it when I see my kids quit. He doesn't care about getting his investment back. His investment is you. He loves you.

You had a company that you 100% owned. You quit. Your reason for quitting is because your father did not give you something you do not need. That's stupid on stilts.

Don't do that. If you quit now you will keep quitting when you are 18. And 22. And 30. And 45. And 60.

You published apps. That means you have a business. A business is one or more people producing something that other people (customers) think is valuable. They vote for your efforts by giving you money to show that they value what you produced.

You have a business. Don't throw that away.

You have a father who loves you. Don't throw that away, either.

Dunno, he would have to be a strong man to donate that much to open source after all the hate vomited his way about it.

I somehow suspect he might give money to something else in the end.
No, its just that a really small minority has the chance to be absurdly vocal on the internet.

Amazon introduces 5 new members of the Kindle family
Also female dev here - I think we all have our unique story about how we stayed in tech against the odds, rather than going with the flow. It might be helpful if we could, as women still working in the industry, compile a proper set of documents about the challenges we faced. It might help if there were just more details out there rather than the few stories we pass along when a post like this comes up.

Definitely easier now for the kids though - I've met 9 year old girls lately who are rocking python/robot dev and if they can stay in all-girl schools through secondary school (or have a very female-supported CS dept if mixed) they'll have good chance of staying in STEM.

I also have to say, because this is fairly recent for me, I've become less and less of a dev myself and more management and I'm having a blast. My years of dev has really gelled with the demands on product development and I very much enjoy the dynamics of running a team - something I never thought I'd find interesting. So it's something quite new for me, and as I know it's more common to see women building a career in management rather than thank of themselves as part of the coding team but I can see clearly how having more dev experience just makes you all the stronger. Might be a compelling argument for those going through school with their eye on an executive position for their future.
Even more so with syntax highlighting: http://i.imgur.com/pDSUIb5.png
That's just confusing because I didn't give up the MacBook willingly. I told him I didn't want to work on it anymore with him because he didn't seem to into it as much I had hoped. I even gave him the offer that I'll stay if it was split 70/30, but he said no. He's even taking it another step by only allowing me to access the Internet for school now.
Anxiety and Depression often go together. There are neurophysiological reasons for this. I found that lack of quality sleep, energy drinks and prozac was a really bad combination.

Long, Long before there was any shortage of drinking water, the various water authorities would simply increase the prices of water to levels which reduce residential usage.

The problem in California isn't lack of water for individual use (for the most part, there are a few small communities that are having to truck in water), it's the impact on Agriculture, which is hugely important to the economy of California, and our general food security.

If you were wondering why there aren't more water restrictions for individuals, (Like leaning on people hard to take shorter shower, or use low-flush toilets, or ultra-low-flush toilets) - here's why: Changes to individual use will only have a small impact on our water use - 80% is used for agriculture. Individual restricting use by 20% will only have a 4% impact on overall water use.

With that said, there is a lot of room for California to transition to a "Desert Water Existance"

In 2011, the average californian used about 326 gallons/day of water. With water restriction, that can, with a little bit of expense, and changes in landscaping (no green lawns), be brought down to 150 gallons/day, and with a bit more expense (typically around the toilet), be brought down to 100 gallons/day with some lifestyle changes (typically shorter showers).

On the flip side, California almonds use 1.1 trillion gallons of water each year. That one crop uses enough water to support a population of about 30 million people @ 100 gallons a day.

For individual water use, though - a lot of the California population is right beside the ocean. Desalination costs about $0.75/cubic meter (264 gallons) based on recent Singapore Desalination plant deployments. If we didn't want a lifestyle change, then 329 gallons / day * 30 days / 264 gallons * 0.75 = about $28 to generate the water needed to maintain our lavish California lifestyle (add some more for distribution, which is reasonable for coastal cities without distance or elevation for pumping.

This only works for individuals though - Agriculture needs cheap water to be sustainable, and much of the farmland is too far away from the coast (or too high), too make for economical distribution.
I booked a spot and will be from either Ingleside or Tenderloin.
Hehe. Based on the previous pendantry, it blended in. I'll take it as help then. :D
This particular quirk also holds true of, say, Ruby or Python:

256 is 256 # True
(2**50) is (2**50) # False

albeit without Java's fear of operator overloading and the counterintuitiveness it causes.
It's not clear from the (beautiful!) article, but 4 times as much water goes to agricultural use than to municipal use in California. People won't die of thirst in California, but crops aren't doing as well.

In particular, orchards spread through much of California's central valley. These are perennial plants (trees or vines), living decades in some cases.

If you've mortgaged the farm to plant acres of fruit or nut trees, you're not going to let them die in a drought. You'll fight hard for any running water you can get your hands on, and then you'll dig wells and suck as much water out of the ground as your trees need.

Groundwater has been (uncharacteristically!) unregulated in California, so aggressive ranchers or farmers can draw down the water table, threatening their neighbors' wells and causing a 'tragedy of the commons' situation and a race to drill. Sucking all that water out of the ground has all sorts of environmental concerns - as a result, California just passed laws to become the last western state to regulate groundwater usage.
young homie, let me break it down for you.

do you understand how much money mother fuckers are throwing at developers?

if you learn to make a specific type of app and then try to sell it you may or may not get any business from the app store but you will have obtained the skills necessary to repeat the work for someone who has ca$h - forever in the future you will be able to provide this service. learn and build as much as humanly possible mane.
I don't know what an eid is but if you had a free app with enough users that you knew you needed to start charging NOW then you wouldn't have to convince your dad to pay for an llc... you'd find the money yourself. You can get one online for cheap.

I'm a dad. I can tell you i wouldn't need to know anything about what you are doing to know if there aren't hundreds of customers interested and a real high quality product done and dusted and on the table then its too early to get bogged down by paperwork. you are in the r&d phase right now and that is a good thing. you are light and nimble, move fast! When you have a winner, you'll know.

I remembered Eric Raymond answering this. (Confession: I remember it because his response struck me as very odd.)

I know right? That 85M is a real drain on my 16GB of memory on my macbook, amirite? What year are we living in when people nitpick over native performance. Is vim too heavy because pathogen takes ten fractions of a second to load more than pine?
A bit of a tangent, but I actually shipped 0install on a system I built a few years back. It was intended to be a way to help users manage plugins. 0install is a really fantastic idea. However, the lack of packages and community eventually made me regret that decision. If I had to do it over again today I would have used docker.

You could say it's a raw deal if you think patents should exist. If like me, you don't, then you could say it doesn't go nearly far enough, and should instead terminate all rights to both the patents and the copyrighted work if you attempt to assert any patent against anyone, anywhere.
Not a lawyer, but RICO has to do more with conspiracies that try to hide crimes by assigning the individual acts to underlings.

And it's not a racket if what you're threatening is legal, which this kind of abuse of patent law unfortunately is.

Show HN: ShopMyApp Photoshop extractor
ShopMyApp is a prototyping solution intended for designers that allows a Photoshop file to be exported as an interactive device prototype.

Example JSON: https://www.dropbox.com/s/fjexrhdy4uctge4/applewatch_health.json?dl=0
Example texturemap: https://www.dropbox.com/s/2x7uxi219cpi3me/applewatch_health.png?dl=0

Part of the solution is a Photoshop plugin that exports a PSD as a texturemap and JSON-formatted metada about dimensions and texture coordinates. This is pretty cool from general perspective and might have other uses also.

The exporter is free to use so feel free to try it at http://shopmyapp.com. Also the question we had in mind was if you see any potential in this kind of thing. Like if we'd develop it to certain direction, could it be something to pay for?
Apple could have handled the lineups better but they make for such good publicity.

Why does it say the cdr of (list 1 2 3 4 5) is 5, instead of (2 3 4 5)?
we do have the ability to make relatively stable environments in which the necessary components of an ecosystem can thrive.

Only with the inputs of massive amounts of energy and additives -- fertilizers, pesticides, and cultivation supplied directly by humans (or our machines).

The energy intensity of modern ag is many, many times higher than of natural environmentments. Food production in the US requires ten calories of fossil energy for every calorie of food energy produced, in Europe it's closer to a 5:1 ratio.

A sustainable agricultural system would require that the output energy be greater than the input.

I experience the same thing with devs and 'done' all the time.

"It's done; it just has some bugs that need fixing."

To be fair, I've said this sentence myself in earnest several times.
If it's prose, I write one or more essay(s) on the topic after reading the topic and mulling over it for 1 or 2 days.

Oh - and this one makes me look crazy but here goes nothing - I teach it....to myself that is, in my own mind that is, usually while exercising! How weird is that! I become these 2 persons in my head - 1 is the teacher, 1 is the student - and I pretend that teacher-me is teaching the subject to student-me, using own vocabulary. Sounds weird, but it works for me.

If it's programming, I implement the concepts I read.

If it's math, I write notes, solve related problems and try to come up with related corollaries.

In general, using whatever I've read in some way seems to help me a lot.
What sense definition for you thanks!

Developing Android apps isn't an intended use case of the Chromebook. As such, Chrome OS devs can still "eat their own dogfood" without developing Android apps on a Chromebook.

I work for a navigation company. We deploy navigation software on 3rd party, purpose built hardware following model analagous to Chrome OS and the "Chromebook" moniker. Even though I use our devices in my car, would you say that I'm not "eating my own dog food" because I'm not writing software on the device in my car?

I downvoted you because you make very bad points:

Being inclusive: Yeah, it's extremely inclusive, The most famous videogame in the world is about a Italian plumber, the most sold videogame in history is about a redneck, a black man and a Russian man. The most famous puzzle game is about a women in a experiment. They want the prime time on more AAA games? So you think giving them the main role in GTA would make them happy? I don't think so, they would scream "Women are not violent, this is sexism!"

I'm "brown" by all US definitions of it and I couldn't care less for "more brown people in videogames".

This is true for more rural areas, but the bigger cities (i.e. San Francisco) don't share water with farms. Farming does use a ridiculous amount of water in aggregate, but it doesn't do us any good to discourage city dwellers from their responsibility to conserve.

That said, it's pretty obscene to drive through the central valley and see people growing rice for acres and acres. In the desert.
Thermodynamically speaking, a perfectly reversible computer which erases no bits (and creates no entropy) approaches zero watts per operation to run.

Kurzweil has pointed out that one can think of the 10^15 state changes per second going on inside a 1Kg rock with no outside energy input as a computation device.

Ok, so at 28 minutes, he's referring to some quantum mechanical lower bound to change a bit. I imagine the rock is using that really tiny amount of energy from the outside environment.
I'm still a little confused and will have to go over some code or something to really understand the limitations of what transducers can do... can any transducer be used in a "parallel" context (like map and filter) or are they limited to a linear context (like the fold makes me suspect)?
