It's very interesting, but it's only the strictly minimal amount. It doesn't include the additional weight of the rocket and fuel.

Let's estimate that. [From: http://en.wikipedia.org/wiki/Ariane_5 ]

The total launch mass is ~800T and the payload to ES is ~20. All the energy calculations are linear in the mass, so we have a x40 factor.

But obviously not all the rocket and fuel reach the ISS, so not all the initial mass should be lifted and accelerated. We have to make some kind of differential equation that depends on a lot of details that I don't know. But from similar calculations I guess that a x1/3 factor is not very far from the correct number. Let's be optimistic and pick x1/4.

So, if the minimal is 1.6 c.b., then my uninformed guess is that the total amount is 1.6x40x1/4 =~ 15 c.b..

I'd really like to see a estimation made from someone with more knowledge, or one based in the energy contained in the fuel.

This is the only HR-related legal action I have ever seen succeed against a company I've worked at. It is so difficult to defend these things that professionally-run companies apparently just settle immediately. I think there's a reason both Grellas and D.C. are warning you all so strenuously about this problem.
Ask HN: How to sell my startup?
Just wanted to ask the HN community for some advice on how to sell a start-up. We launched http://www.dingadeal.com just over a year ago and feel like we can't bring it any further. It has a lot of potential, but unfortunately due to other commitments, me and my two co-founders feel we don't have the time to bring it any further.

Below is information about the website, any ideas how I could go about selling it and how much it is worth?
I have tried flippa, but haven’t had much luck.

What it does?
Dingadeal.com is aimed at groups of 8 people or more, we take the hassle away from your group trip by giving you a platform where hotels can tender for your group. Tell us some details about your trip and we will contact all the applicable hotels on your behalf ensuring that you get the best deal possible!

What it is has?
- Microsoft stack - asp.net/c# mvc, ms sql, azure. Html 5, javascript, jquery is also used in parts
- High quality design.
- Inventory of hotels who are actively engaged in the site from the UK and Ireland.
- Ranks high for certain keywords such as "hen party in Killarney" and "group golfing in killarney".
- An SEO strategy that works and can be replicated worldwide.
- 497 followers on Twitter
- 512 likes on Facebook
- Google+,Linkedin, youtube channel.
- Good relationship with developers to continue development work.
- In built room management and group payment functionality.
- Explanation video - http://www.youtube.com/watch?v=v1j3ylK00SU

What it needs?
The current revenue model doesn't work. We rely on the group to complete the payment online when they usually need direct contact with the hotel before payment is completed.
The ideal revenue model would be a mix between getting paid when a group completes a payment and offering hotels the option of being a "partner hotels". This would give them higher ranking on the results and maybe further information about the group such as the lead group members telephone number. You could also sell auxiliary services around the group trip. e.g. if a group planned on going to Killarney you could put them in touch with hotels, golf clubs etc in Killarney. These could be your "partner golf club" in this area. These services would pay a monthly fee for being included in the Dingadeal mails.

A number of websites with a similar idea have implemented revenue models that work.
http://www.hotelplanner.com
http://www.iknow-uk.com
http://www.meetingsbooker.com

Who would it suit?
Someone already in the hospitality sector, ideally if they were selling into this space they could add this as an add on to their existing product. No reason why someone who is not in this space,but with technical expertise could also make it a success.
If interested contact kevin@dingadeal.com
I wonder how this correlating data can be used in cases of copyright infringement where the alleged infringer is only identified by IP address. Could a correlation between IP address and real-world identification be made by subpoena of FB records?

There's also a BBC series titled The Wonderful World of Albert Kahn that includes a selection of images and film with a little commentary thrown in for context. I really enjoyed it.

This looks like a great project. My only feedback is that in these types of situations, the tendency is for people to use the tools they already have. For the London riots that was BBM, for Tunisia and Egypt that was Facebook and Twitter.

This could be particularly problematic if you're targeting an internet blackout situation, because people will likely use the tools they have until they can't anymore, at which point it will be too late to download yours.

So you might think about positioning it differently, or coming up with an application for it that people will enjoy outside of a crisis situation, so that it will be one of those tools that people already have.
I agree with you to an extent. It's why I would choose different problems to solve than what Mr. Gates feels are important. However, I don't think the Gates Foundation and its efforts are in any way a net negative.

Perhaps the poacher from your story would not need to kill more elephants to feed his children if the general condition of his country were better, and the economy supported other endeavors more readily (and prosperously) than poaching. In fact, if you believe the Rand think-tank, "first world" inhabitants produce less offspring, and much of the developed world is facing a looming underpopulation crisis.

I know many Western European countries have a birthrate that is lower than the replacement rate. This may be the case for America as well, but last I heard our population was still rising, with immigration also being a contributing factor.

In any event, you're right in that the answers don't come easy. I think the fact that Mr. Gates is willing to make the attempt, and is showing some signs of success (whether it's the right success metric is certainly up for debate) is to be commended. More people should aspire to philanthropy and there are certainly worse role models than him.
Stata won't work on data that don't fit in memory. It is fast, but it isn't an option for very large datasets.
I think that is an unfortunate attitude. I always opt-out. It's a form of civil disobedience and governments don't like that, so they enact procedures that try to discourage people. If enough people opted out, the whole system would come to a stand-still and they would have to rethink the policy. That may mean just removing the option of a pat down altogether, in which case I imagine there will be a large backlash. The real fear for me is that people just become accepting of it slowly over time, until they finally can remove the option and then not enough people will be outraged.
Having to constantly remind yourself that, more or less, "this is happening right now" is a surreal experience. It feels like the cheesy curated montage at the beginning of a smarmy independent film - but it's not. It's just random, unfiltered views into things people are filming all over the world.

I had no idea how many of us could connect over our love of filming coffee preparation, or cats, or traffic, or terrible attempts at stop motion. Hey look another magic trick!

Seriously though. Fascinating and, for now, quite engaging. I vote against re-wind or links to previous clips though. Keep it ephemeral and impermanent. Like real life - a moment is here, then it is gone.
With OXO and quirky, we're in a realm where hiring a team of $700/hour lawyers would wreck both companies. For Samsung and apple, the cost of legal advice is a rounding error.

While you make great points, the cost/risk of designing a cutting board or a dustpan is orders of magnitude lower and the response should be commensurate.

I don't think it's wise for Apple to not defend the things it believes it has patented but that's an argument for a horse of a different color.
Essentially it's a form of terrorism.

T-mobile prepaid requirement: "you have a minimum of 60 consecutive days of active service with T-Mobile"

AT&T prepaid is much worse:

"Requirements for prepaid wireless plans with AT&T branded phones:
You have had AT&T service for six months or longer
You can provide a receipt or other proof of purchase"

The last line illustrates how carriers are dictating policy in an effort to subvert the secondary phone market.

Even more frustrating in the same link you will see that certain AT&T phones are "ineligible" for unlocking presumably due to some arbitrary restriction.
A couple of years ago my wife's 2 years old nephew was diagnosed with retinoblastoma (eye's cancer). I contacted the world's best hospitals and was told that the treatment will cost hundreds of thousands dollars.

So I tried to get some financial help from related funds and organizations and contacted all of them I could find on the internet.

Guess what happened: 90% of them just ignored me, and the rest told me that they are not helping sick kids, but only doing research work. One came up to cover up to $3.500(!) if I provide a bunch of documents I was sure I wouldn't be able to gather in a short term.

On web pages of such funds you normally can easily find a button to make a donation. But try to contact them if you need help - you will be surprised how difficult it is.

So we (relatives and friends) collected as much money as we could, the kid was receiving treatment in one of the local hospitals, in the end both of his eyes got removed. Maybe the same would have happened in those best hospitals too, but if there was even the slightest chance to keep his sight it certainly would worth any money.

Bottom line is - I don't believe in cancer funds any longer, and will never donate any dime. In fact I'm not even sure that they spend all money for "Research", they might be just another way to avoid taxes.

May be Bill Gates fund is different, I hope so...
Even though this ruling seems to be in favor of liberty, I'm disheartened to read the excerpt of the appeals court ruling in the article.

We take heed of [Benjamin Franklin's] warning and are therefore unwilling to relinquish our First Amendment protections—even in an airport.

The court finds itself tempted to set aside Constitutional language for the sake of the nebulous idea of "national security." Next time they're faced with a ruling of this nature, their temptations might just get the better of them.
And the obvious point: we're all paying these fees already, only they're spread indiscriminately across all customers, including those who pay cash. Saying a surcharge is 'penalising' me for my payment choice isn't much less silly than saying that a retailer's pricing structure 'penalises' me for preferring a luxury brand.

I always opt-out too. It's a matter of principle, I refuse to have my privacy invaded like that without being able to see who invades it, plus it creates more work for them.

Also, I rather enjoy pat-downs. They're like a massage, and the TSA agents wasn't too overt with the problematic regions, although they did try psychological manipulation to make me feel bad (refusing to let me touch my stuff, making me take my belt off, etc). I didn't mind, though, opting out felt like a big "fuck you" to the TSA.

Of course, I don't even live in the US, so I've only done it twice.

I don't necessarily disagree with much you wrote, but this piece about corporate charter schools,

Alas, free market means monopoly, not more parental choice.

seems like it came out of nowhere. Since charter schools entered my area, my kids have gone from two choices, the local high school and a gifted program for engineering students at a local college, to many choices, includes a performing arts school, a science and engineering school for the "non-gifted" and many others.

As a parent, I have concerns about how charter schools impact the local school budgets, but monopoly is the exact opposite of the word I'd use.

So I'm curious about what logic brought you to that statement. Your comment was well thought out, so I don't think you are just pulling statements out of nowhere.
I upvoted you.

I'm sorry you're being dismissed as a Malthusian.

I also believe we humans are in deep trouble.

I volunteered at a treehugger organization for about a decade (the 90s). Trying save the birds and the salmon. These people were scientists working on policy. Like saving critical habitat such as wetlands.

Etc.

Pretty much everything I first learned in the 90s has come true. And the actual numbers are worse than the predicted worse case scenario (eg climate change).

I personally believe we're past the tipping point. Meaning climate change has entered into a positive feedback loop where even if we stopped burning fossil fuels, atmospheric CO2, methane etc will continue to increase. Because of the arboreal forests continue to burn and the tundra continues to thaw and the ocean (the biggest carbon sink) continues to acidify.

To stop this progression or even reverse it, decades from now, humans will have to aggressively retool our industry to remove CO2 from the atmospheric.

Weirdly, I'm strangely optimistic. I think it's possible. I'm not willing to give up hope.

I sometimes wonder if I'm just fooling myself. Things are so bad, I just go to my happy place. Like Sam Lowry in the movie Brazil.
this is very cool!, last year we had a same idea. but we didn't finish it.
at first, we decided to build a microblog which relies on geolocation to find nearby blogs. but the content is actually hosted on a server.
but later, we had more and more ideas added to the project, it got too huge, we eventually gave up.
>But I think most people also think that a guy who burns movies to DVDs and sells them on the street corner is an asshole.

It's not about killing an underclass. Human beings are selfish.

>Educated societies have far fewer children than non, to the point that some first world countries are losing population.

You're citing statistics without understanding the reason why. Education means a higher household income which has become less so during the recent economic crisis. The traditional reasoning, while crude, of why poor people have more kids is because they have less money. What they can do is have more sex because they don't have the money to do anything else.

This is a great point. We were trying to figure out a way for people to first pass the app between devices locally so it could spread and be used in a situation where the internet was down, but we haven't figured anything out there yet.

On the firing, my first real job almost didn't happen. It was for a government contractor and another group was trying to slot its bad apple into the position. She was minority woman who was often found sleeping on the job, hanging out for hours in the women's restroom, etc. As a minority woman in a government job, she was impossible to fire. It wasn't until the politics settled that I could be hired.

The real question is whether this is worse than the alternative[1]. The alternative was women and minorities unable to get jobs or stuck in their current job. I think in many areas our society has moved past that, but not in all. It is certainly worth looking at the regulations to see if we can improve the situation.

1. Unions are a completely different piece of the equation, especially when it comes to teachers. I don't know how you break that stranglehold, short of increasing completion by including schools that don't hire unionized teachers, but that's if you can even hire a non-unionized teacher.
