1) Lack of sleep is used as a form of torture in some countries. Your wife needs to be able to sleep whenever the child is asleep.

2) Feeding is often something that people worry about. Check with a health visitor / doctor; if the baby is thriving then everything is okay. Maybe try different teats? Make sure the milk is the right temperature. Try different chairs.

If none of that is working you could offer to do alternate nights for a week. This allows her to get at least some rest.

Your wife needs support through the day. She needs to have time just for herself, and time with friends, and time with friends and the child.

Post natal blues and post natal depression do happen and are normal, so support your wife if she wants to get treatment.

Things do get a bit better when the child is sleeping longer. After about 6 months you can start techniques to help your child sleep through the night.
This is one along the lines of 'wouldn't it be nice if'. Yes, it would be. You can get an idea of how effective this will be if you paint a good sized chunk of wall with http://glonation.com/ glow in the dark paint. The paint will likely have a much higher density than any plant based set-up will be.

This may be useful as emergency lighting in a jungle but I highly doubt that we'll be replacing LEDs, fluorescent or even incandescents with this technique.

Apologies for being terribly pessimistic but even if the project gets funded and the goal is successfully achieved I can't see the utility.

Has there been any work done on an estimate of efficiency, some sort of modelling about what reasonable expectations are with respect to output?

It's a super presentation complete with HN voting ring, congratulations on successfully gaming the system. If they are just as good at the execution then this can't fail.

edit: after reading the risks and challenges section:

"We hope to have a plant which you can visibly see in the dark (like glow in the dark paint) but don't expect to replace your light bulbs with version 1.0."

So that was pretty much spot on. Then:

"The more money we raise, the more we can refine our designs and the stronger the effect we will get so please tell all your friends about the project."

That's not very honest, there is no way there is a direct relationship between the money they raise and the effect produced, these things typically follow a saturation curve with the upper limit being pretty hard and rather low compared to other ways of generating light.
Without wishing to kick even more sand in your face, I thought it was pretty cool. I was as impressed with codepen (which I hadn't seen before) as I was with the demo (oh, they really can do some pretty neat stuff in javascript these days).

It's like this video: http://www.youtube.com/watch?v=GcDshWmhF4A

Where a guy builds a binary adding machine out of wood and marbles. I've seen them before. I've even seen nicer ones (more expertly constructed). His little counter / adder isn't really a feat in any way. I could even show you how to build a vastly better one with a CPLD. Yet, I am still impressed, and amused when I see that someone has built one. Wood, Minecraft, Little Big Planet, anything else.

But, don't stop being a hater. I even got something useful from your post 'Advanced Character Physics' by Jacobson. which is interesting, and which I probably wouldn't stumble across on my own.

For that matter, it doesn't address the work/life issues faced by the poor, or immigrants, or non-whites, etc.

I agree with you that men also face issues of work/life balance, but it seems unreasonable to expect everybody, every time they speak about a topic, to address all tangentially related topics.

It's not a zero-sum game. By addressing work/life balance issues for women, a topic which she has personal experience with, the author is not depriving other related issues of oxygen.

I think it's okay for a person or group to tackle one issue at a time. Other individuals and groups can tackle other issues. No harm done.

Thanks, and yes and no. When I realized I'd found a decent sized niche I had to make a decision: do I let it sit and coast/build something else, or do I invest more here?

I've decided with the latter, which will play out for at least the next year. Jury still out whether it was the right decision.
Y Combinator's Value to The US Economy
In fact cooling solar cells does make them more efficient. It's just that the effect is small because the "high" temperature is already so high (the temperature of the incoming photons is effectively that of the surface of the sun). A Carnot engine working between 330K and 5800K, ie a reversible solar cell, would be 95% efficient. If the cell's temperature were dropped to 300K it would be 94%. So we can estimate the efficiency change for a 30 Celcius cooling of the cell at 1%.
Patrick Henry is a little strong for this day and age, but "Give me liberty or give me 0.000001% chance of death", works perfectly well for me.
Problem is that if the browser doesn't support viewing of the file, then both links will cause a download, which can be confusing to the user. I think we need a way to see if a MIME type of a file is supported by the browser (including its plugins.)
To be fair, there are a number of advantages to having content in PDF's rather than HTML. For example,

1. The formatting is more static. Papers and memos and other documents are created and intended to be artifacts, not just mutable information, and PDFs can preserve that better. In 10 years, the PDF will look more like it did originally than HTML in tomorrow's browsers.

2. They're more durable. As a self-contained document, they don't rely on externally served files such as JavaScript and CSS. Ideally most HTML files are capable of presenting their semantic content even when you strip all that away, but that's easy to get wrong (especially with the advent of client-side templating and JavaScript frameworks). It's easier to archive a PDF than a web page, just save it to a thumb drive and it's pretty much guaranteed to work.

3. It's every bit as future-proof as HTML. With multiple independent implementations of PDF viewers, many of which are open source, the format is not going away. It will be readable for years to come.
Wow, that's really sad lead-in: A mom who is "famous", so her daughter introduces her to her friends via Google Search, instead of meeting them.

> "they have stages so that you don't spend 99% percent of your fuel pushing engines and tanks into orbit"

In fact you can kinda make a rocket that can reach orbit that doesn't have "stages" but rather jettisons engines themselves. Early Atlas rockets did this: they had one set of fuel tanks but two engines. About two minutes into the flight they would jettison one of the engines.

So that is a better hacking strategy than ddos'ing mt. Gox. Clearly if you can make the DOW drop 127 pts on demand you can figure out a way to profit handsomely from that. The simplest being to short a basket of stocks that are going to be affected and cover the shorts with buy orders. Harder to track than a 'one stock shock' as they say since by their nature DOW stocks are heavily traded and people are guessing all the time if they are going to go up and down. Spread $15 - $20M in shorts across the basket, cover them on a 15% net gain in proceeds and then shoot the canary.

Hey everyone! Thanks for the concerns, I am a new commenter, but like <<gruseom>> hinted, I have been reading HN for years, so this is not my first impression of the community. I also come from a culture where "gee why aren't you married yet" or "why don't you make more kids" are considered "safe" questions to ask to people, so the deleted-but-quoted comment was not offensive to me (but having also lived in the US, I understand that it could have been).

Anyway, just to reply to some of the comments: I mentioned the # of kids to present some reasoning behind the biological limitation to get married at 27. But kids and family are still fairly distant in the future for me, so it can change, I recognize that (i.e. haven't totally boxed myself in).

But let's even look at the more interesting side: men who want families have the OPTION of staying single well into their thirties without limiting the number of people who they could statistically find a match from. A 35 year old man has many more potential marriage partners than a 35 year old woman. And I think that is not going to change until it is as common for a 35 year old woman to date and marry a 5+ years younger man as it is for the reverse case.

I should mention that I am super open minded about these things - I am just observing some realities around me, not commenting on whether they are good or bad.

That's funny, because I have the opposite anecdote; I have been regularly converting OS X user to Kubuntu Lucid/KXStudio (with backports) for the last year or so. Know all those guys that are avoiding Lion and Mountain Lion like the plague that they are? Yeah. that's my market.

Tons of people with 3yo MBP's with an install of Snow Leopard, looking longingly at how pretty and useable my little powerless Netbook with 2GB of RAM is with OpenOffice/Dolphin/Blender/Gwenview/Firefox running and 40+ tabs open. They can barely run Safari, iPhoto, Mail.app, and Skype at the same time without constant beachballing, so they sit in quiet humility while I actually get stuff done.

Once installed on their computers, an install that just works, I grab AppMenu (QML) from kde-look and replace the default one. At this point the MBP owner has a better OS experience than Snow Leopard could/does offer, and we haven't even done any tweaking yet. like f.lux or redshift (which you can grab from a ppa). I don't see the crashes you guys do on these apps, oddly enough. just works for me and my customers.

I love you Mac guys, really. You pay top-dollar for your hardware, and then Apple forgets about you in less than 4 years. I almost feel like I'm a rescue worker for abused and battered Apple customers.

He's referring to freedoms to choose Verizon, Sprint or AT&T; to go with iPhone, Android, or even Windows Phone (for those odd fanatics); to pick a foreign or domestic hybrid vehicle; to choose Democans or Republicrats; and maybe the freedom to move to a new school district to get a better education (until the Department of Education takes them all over anyway).
There's a difference between the business and the job. Being a Barber doesn't scale in the same way a search engine or car manufacturer with 1 employee doesn't scale. There's no reason a company based on haircuts can't scale though by hiring more employees, and without knowing where you live I'm sure some hairdressing chains exist.

If you mean that scales exponentially, so the employee-value graph isn't linear, I guess that'd be different and you're probably right.
"Don't over commit yourself or your team."

Most of the time, I am forced to obsess about it because upper management decides me to put me in impossible situations.

Not that you need one more thing to do, but my wife and I (proud parents of 4, with our youngest also 2 months old), have found this book to be very helpful in learning how to guide a newborn into a good sleeping schedule.

http://www.amazon.com/Becoming-Baby-Wise-Giving-Nighttime/dp...

If you just do one thing from that book, choose to regulate the sleep/eat/awake cycle of your child.

And now some generic pointers you may have already heard:

- Every child is different, but parenting approaches not so much. Pick an approach that emphasizes the goals you want to achieve (regulate sleep, minimize crying, parental free time, etc.) and adapt it to your child in the particulars (approach says feed every 3 hours, but Sally is hungry after 2.5).

- Getting enough sleep is hard, but important, for both of you. If family can watch the baby so one or both of you get naps, absolutely take advantage of that.

- Be patient with your spouse, assume her intentions are good and give her the benefit of the doubt.

- In a time when your wife is resentful of you, ask her directly if there's anything you can do to alleviate some burden from her.

- Parenting is a constant reminder that you don't know what you're doing, so don't feel bad about that. Bill Watterson put it rather well in C&H: http://qph.is.quoracdn.net/main-qimg-a0c61445794a690aa3a00f4...

- It does get easier, especially when the kid drops a middle-of-the-night feeding.

Lastly, I just want to say that you aren't alone, our 7 week old is still up every 3 hours through the night, and lately our oldest has been waking up at 4:30 (which does not coincide with a time that we're up with the youngest). This has been the hardest lack of sleep to adjust to out of our 4 kids, and my wife is exhausted. Still, we're as close as a couple as we've ever been, and you only get that from doing whatever it takes to survive the hard times with someone else.
There is an assessment of the energy efficiency here: http://2010.igem.org/Team:Cambridge/Tools/Lighting
"And the problem is that, hidden in the parts you don’t fully understand when you start, there are often these problems that will explode and just utterly screw you."

I completely agree! I also find myself telling my bosses that 80% of the feature takes 20% of the effort/time. Then a wall is hit and the remaining 20% takes 4 times longer (80% of the time).

ADD: And as you go along, the cone of uncertainty hopefully narrows but when you hit one of the exploding "we didn't knows!" your original estimated time/effort is too small. We try to account for these by including some "uncertainty buffer" but then the stake holders get mad when they see these large effort/time values at the start of a project. It seems stake holders don't really want to hear the truth and the possibly ugly, only the sweet sound of nothing going wrong.

Giving those the-stars-align-and-nothing-unforeseen-happens estimates do a disservice to everyone and/but then you have other developers/consultants/etc. competing and vying for work so they try to undermine and and undercut the more realistic estimates and we find ourselves in a downward death spiral similar to trying to compete on price alone.

Don't Spam Your Users: Batch Notifications for Rails
Presumably the reason why inmates don't have unfettered access to the internet is to make sure they're not running some empire from behind bars

This is the argument that jailers use, but it really doesn't hold water. The vast majority of prisoners pose no threat to the public, online or in person. Preventing Internet access is nothing more than a way to increase recidivism, which keeps prison guard union dues flowing. This is why various correctional officer unions are constantly lobbying for ever more harsh criminal laws and mandatory sentencing schemes - often for victimless crimes. This strategy has worked; the US incarceration rate is the highest in the world - even higher than countries we think of as crazy that tie criminal laws to religious beliefs. Countless lives have been needlessly destroyed, and countless children have grown up without fathers, so that prison and jail guards can have make their $20/hr.

Some form of Internet should be allowed in correctional facilities. Since entire college courses are readily available for free online, you would think it would be a top priority to grant access to them. However, reform simply isn't the goal of the people that have the power to make these decisions. By enabling prisoners to better themselves, they would literally be working themselves out of a job.

Lift is optimized for maintaining persistent connections with users and maintaining their state for an easier programming model and probably performs well at that.

If your use case actually matches these benchmarks then yes, Lift would be a poor choice.
Actually, I'd say there's only one reason for the existence of prisons: confinement. As in, removing someone who could otherwise present a physical threat to others.

Prisons might be a deterrent, but locking up people who never caused physical harm to others is insane. Those should be alternate sentences.
I pretty much agree. Correct me if I'm wrong but Dropbox were the first to have come up with Camera Upload feature, which basically makes any average user go trouble free with their cellphones, tablets, snapping away photographs knowing that they will be ready on their desktop to view if they want to.

Google+ does that too now, but this is in fact a killer feature which has been adopted well by the average folks out there. So yes, Dropbox is not just about file sharing anymore.
There are orders of magnitude power differences between "glow" and "illuminate".

First, your eye has a logarithmic response to light intensity, which is great, it gives you nice dynamic range. But if you are judging photons/second, you are going to do a terrible job. It doesn't take many photons for your to perceive dim light, particularly when you are dark adapted.

Looking from the other direction, say that plant has about a 10cm x 10cm total leaf area. It gets the equivalent of 4 hours a day of sunlight at 1000 watts/sq meter (typical of earth). So 40 watt hours of energy per day hits it. Wikipedia says 3-6% efficient for photosynthesis, that gets us down to 2 watt hours per day. That gives it 100mW to live on. If it put all of that into glowing and were as efficient at making light as an LED it would make about the amount of light of an indicator LED that says something is on, but isn't silly bright. I think that is still orders of magnitude high. The plant still needs to use energy on growing, and the biological light making process is probably not as efficient as an LED.
Good question! We'll update the amounts when the dust settles. I'd expect our cost to be ~25% of the poster price.
