Ignoring surface tension effects, and assuming a much larger and relatively fixed volume and density of supporting water compared to that of the melting iceberg (i.e. not an edge-case of huge iceberg floating in a very small amount of water) and no loss/gain of iceberg mass over time to evaporation (which can be non-trivial in dry polar air) or precipitation, the water level will actually BOTH increase & decrease over time depending on the RATE of melting which depends mostly on the temperature of the surrounding water and the amount of wetted surface the ice has in contact with it. For most icebergs, the wetted surface also changes significantly over time as its center of buoyancy changes--hence iceberg rolling and sheer surface break-offs.

We're also assuming the perfect case of relatively pure fresh-water ice and sea-water salinity. When changes in salinity and "dirty-ice" are factored-in, it gets even more complex.

It's actually a very non-trivial solution which, among other things, is why predicting iceberg lifetimes and danger to shipping lanes in the open seas is still very much an art.

In the end, the iceberg WILL melt and a net additional volume of water will be added to the sea, but if one could measure things that precisely the sea-level change relative to the melting process will fluctuate up and down over the lifetime of the berg.
For the Jobless, Web Sites Offer More Options
I've followed this since it started; it has understandably caused a great amount of anxiety in the online poker community. Almost everyone was happy that the cheating was exposed, but I think most players would have preferred it if the 60 Minutes episode had not aired.

Prior to the 60 Minutes piece, knowledge of the cheating was limited mostly to online poker aficionados. Now that it has received national media coverage, casual poker players everywhere are likely to hear about it. People who were already hesitant to play because of online poker's grey legality and funding difficulties are not going to be swamped with "Oh, you know online poker is rigged. I saw it on 60 Minutes." Combine that with the waning interest in televised poker and the UIGEA legislation and you've got a bleak outlook for the future of online poker.

In the end, I think the 60 minutes episode will deal in a much greater blow to online poker than the money the cheaters stole.
you are paranoid, dude :)
Open Source: The Model Is Broken
The only way that the water level could rise is if the average density of the submerged rope and anchor were less then the density of the water. However if this were the case then the anchor would not reach the bottom due to having insufficient mass to submerge the rope, and the water level would remain the same.

how confident/comfortable are you with the idea of working on this company as your sole source of income? ... really, you need to honestly answer that question first.

second, do you have a co-founder? though one isn't necessary it doesn't hurt to have one (or more).

to go with option 2 (which is my knee-jerk recommendation), answering affirmative to the first is required, for the second it's "strongly encouraged".

also if you have a spouse, sig-other, or any dependents, it might be nice to (see: you better) talk this over with them and get their input.
I have no useful suggestions, but like @pchristensen, you had me halfway through the title. Most excellent idea. I'm reminded of an old Wired piece by Neal Stephenson entitled "Mother Earth, Mother Board" in which he talks about the 'hacker-tourist.' The only thing that could make it better is to suggest nearby non-geek attractions that I can use to sell the trips to my wife. :-)

I can take a look at a book, see whether my friends recommend it, and so on. It's a fixed, known quantity. A mailing list you've just started up is not. Especially at a price point that's neither:

* Free, in order to attract lots of people and get some network effects happening.

* Nor enough to compensate you for doing actual work to solve problems.

So to me it seems like neither fish nor fowl. If I want to hire a consultant to do stuff, that's one thing, and something I'd spend a lot more than 10 a month on! Free mailing lists are another. Something in between for a fairly niche topic... I'm not so hot on the idea.

America's Other Auto Industry
Perhaps, but I am starting to realize that creating a business isn't the most sure way to get into changing the world. Seth says that it isn't so much about connections, which is true, but at some point it seems like you have to be lucky enough to be in the right place at the right time to get noticed by the right people. This seems like an excellent opportunity to increase the likelihood of those situations.
I would support this as a requirement for reviews. It just makes the entire process much easier for everyone in the community.
What a poor article.

It's pretty much completely devoid of any evidence to substantiate any of his claims.

He states: "The open-source business model is broken." and makes vague references to companies that have faltered but gives no hard numbers, e.g how do the numbers of companies using an open source business model failing relate to companies with a proprietary model?

The article's filled with other assertions that are backed up by vague statements. I mean:

"And therein lies the great paradox: Open-source code is generally great code, not requiring much support. So open-source companies that rely on support and service alone are not long for this world."

A rampant generalisation, followed by a complete lack of any evidence.
Call me naive, but I think it would be great for OSS to have a license that is free (as in freedom), but free as in beer only as long as a certain revenue threshold is not passed, basically, a "pay when you can" model.

Why shouldn't a company that makes 100k/month using linux, etc. spend 0.5% or whatever of their revenues supporting that infrastructure. It could go a long way to improve OSS project funding, quality and long-term maintenance. (I guess it would be akin to a tax).

Another interesting idea with so much hosted software today would be to adopt a sort of "Affero LGPL" (require hosted software to publish the source & modifications of the code, but don't force the whole code base to become GPL). Perhaps allow a fee for keeping modifications proprietary. Not for ideological purists, but pragmatic imho.

Just trying to throw some ideas out there for discussion.
Ha! beat me to it. I loved this line:

Any federal money or loans that goes to Tesla should be through some sort of grant project where other automakers and manufacturers can compete for the money.

The only way direct bailout money should go to them is if they have any IP worth salvaging. Personally, I don't think an all-electric car is "the future" of the passenger car. Fuel cells, PHEV, natural gas, etc. all seem like better options, so I'd rather see federal money invested into these technologies.

I think markessien has a great point. A lot of enterprises don't want their office worker in browsers (however lame that sounds) and may not be comfortable sending you their data.

Yeah, it's not that good. I voted it up just because I think open source business is a fascinating subject and interesting thing to discuss, and if nothing else, the guy was quite involved with it at OSDL.

My take is that 1) open source works very, very well, but that 2) "opens source business" is not really a solved problem, and that the economics of the whole thing are weird and interesting.
This is a prime example of why, back in my high-school trivia team days, I learned to dread questions about science. The problem isn't so much that the writers of trivia questions get the answers wrong (they do, but only very rarely). The problem is that they pose questions they think are simple, but they use real world examples ("an iceberg"), instead of the Platonic ideals they meant to use ("an ideal spherical iceberg composed of pure ice floating in a sea of pure water, neglecting evaporation, on a series of rainless days..." -- actually, come to think of it, it's pretty damn hard to construct the Platonic iceberg!)

When answering a science trivia question you need to work hard to cut your train of thought off at the level of the "obvious" answer before you get too far down the line to computing the "more correct" answer.
The problem is that it makes things very, very complex. What if GE has 10 linux servers - how much do they pay? How about a little startup (that makes 100K per month) that is entirely based on doing custom Linux work? What if I'm in charge of a "skunkworks" project at IBM, with just me and two people working on a new project - do we have to pay?

Basically, you take away one of the critical freedoms of free software with that kind of license, as much as it would be very, very tempting to get some of that money recycled into developer salaries.
Any chance of a web form?

Email sucks for this I want to write a bookmarklet!
I like how Calacanis acts like the $400 million loan has no default risk. Tesla has blown through hundreds of millions already with no profit. What makes him think that this company will be able to continue to fund operations and research as well as pay back interest and principle on a $400 million loan.

All of his "consumer benefits" can be had in other technologies as well. It's not like Tesla is the be all and end all of all alternative powered vehicles. If GM and Toyota are able to put 40-50 mile range PHEV on the roads next year, Tesla becomes even more irrelevant to the average consumer.

The problem isn't bias -- the problem is one actor having more information than the others, earlier than the others. There is no evidence that the RNG was anything other than fair.

A related attack on poker is just stuffing a game with colluding players. You don't have to know player A's cards to beat him in the long run if you know the cards of B, C, D, and E (and, if you want to get really tricky -- they can know yours, too!).

Plus, given that this is online poker, you can have players B, C, D, and E be bots, programmed to talk to your server to get the odds, throw enough hands to look reasonable, and bet big only once in a while when their collusion means The Syndicate rakes in the moolah.

Example: the flop is 5, 6, 7 with 3 different suits. The best hand from The Syndicate is pocket 7s, which is (poker amateur hour commences) pretty strong but not unbeatable. Everybody is out but one player. The next card is shown, and it is a 3. There are two worlds the game could be in now: the world where there are fours available, in which case the adversary might have one. Then there is the world with no fours available, in which case The Syndicate has the best possible hand and will only lose by a freak accident.

The adversary goes all in. The Syndicate checks with the other TEN cards from the deck they saw, notes that they've seen three of the 4s already, and calls, with a smile on his face. (Again, amateur poker player but I'm thinking this is a 95%+ win for the syndicate.)
I haven't been successful with poker software and would like to leave the past behind. The Erlang Journal is both a new business venture and psychological relief at the same time.

It doesn't require a lot of time to share the fair amount of information I collected while writing Hardcore Erlang and the feedback makes it worthwhile, even if the money isn't.

There's a marketing sideline to this as well. A member-only mailing list is a great way to size up the market. Perhaps there's none, perhaps there's a sizable one. If I get swamped with subscriptions then I could invite other experts to help me and, perhaps, sell products or services my subscribers would be interested in.

Also, I have a number of crazy Erlang projects in mind like a Mac Cocoa bridge, trading software and others. I could dedicate myself full-time to writing code for The Erlang Journal, if the number of subscribers allows it.

In the meantime, I don't look to solve all the problems that folks bring up, I just have to solve enough problems for them to keep coming back.

There's also a public source code repo at http://github.com/wagerlabs/thinkerlang/tree/master that you may want to take a look at.
If they will only ever build luxury cars, then no.

If they will work down into lower parts of the market as their tech gets less experimental and less expensive, then yes for sure.
Reminds me of the math test given to one of the WWII characters in Cryptonimicon (Daniel Waterhouse's grandfather).
For typical anchor and typical rope (i.e not metal chain) on a typical boat on a typical lake:

Scenario #1:

1. Negative buoyancy of anchor >> Positive buoyancy of rope.
2. Sufficient rope exists to reach the bottom with some additional rope remaining in the boat.
3. It's a calm enough pond without eddy currents such that, essentially, the only non-trivial forces acting on the rope once an anchorage has been established are isotonic (i.e water pressure).

Actually #3 completely obviates the need for an anchor in the first place, but I digress.

Imagine that one were to cut the rope at the anchor.

The rope begins to ascend to the surface due to its positive buoyancy and the amount of water being displaced will decrease over time until all of the rope is floating on surface and displacing its own weight.

Scenario #2:

The case is slightly different if the rope is under any kind of tension. Assuming a sufficiently strong rope and zero relative boat movement from its anchorage, the negative buoyancy forces due to the anchor are sufficient to overcome drag effects due to the current so the boat is very slightly being pulled under--hence an additional very slight increase in the water level of the pond.

Two additional edge-case visualizations that may be helpful. Think of the "perfect superdense anchor" scenario with a neutron-star and carbon nano-tube rope and a "worst-case" anchor consisting of aero-gel.

The article states that "The open-source business model is broken".

This is wrong, because there is no one "open source business model"; there are lots of them. ESR lists 9 in The Magic Cauldron ( http://www.catb.org/~esr/writings/cathedral-bazaar/magic-cau... )

The article does have a grain of truth in that open source does close off some possibilities for making money from a product.

"Any federal money or loans that goes to Tesla should be through some sort of grant project where other automakers and manufacturers can compete for the money."

Some sort of grant project for clean energy? Some kind of grant project that has $25 billion to give away to worthy projects?

Almost entirely lost in the subsequent discussion was the fact that Section 136 of EISA created a $25 billion fund known as the Advanced Technology Vehicle Manufacturing Incentive Program (ATVM). The ATVM specified that the Department of Energy (DOE) should provide loans, loan guarantees and grants to new and existing automakers and suppliers to encourage development and speed delivery of next-generation cars – vehicles that meet higher standards for fuel efficiency and stretch technology beyond the internal combustion engine. The program aimed to provide “grants and loans to eligible automobile makers and component suppliers for projects that re-equip, expand, and establish manufacturing facilities in the U.S. to produce light-duty vehicles and components that make meaningful improvements in fuel economy performance.”

My impression is that "sell consulting support for open-source products" is a good business model for the individual consultant (in the sense that if you're good at it you can make a decent living at it). It's not such a good business model for an investor looking for growth, because the consultants don't leave behind much profit for the investor, and the only way the consulting firm can grow its revenues is by hiring more consultants.

You're right because they work on battery technology too. They have to in order to make electric vehicles more appealing and they plan on selling their batteries to other automakers.

A guy goes to his wife with a business idea. He has had them before, and his use of their savings has taken the couple's net worth to below zero when the debts that he has incurred are factored in. The thing is, he believes that this business will be different. This is the one that will turn things around for them. A bit skeptical, the wife hears the husband out. At length, the husband finishes his 'pitch'. Still skeptical, the wife tells him that while she would love to help him give this new business a try, they are out of money, and are obliged to start paying down debts at this point. Relieved at being able to blame their situation for the denial as opposed to her skepticism, the wife tries to move the conversation to a different topic. When the husband hits upon an idea.

They still have a sizable sum of money in the kid's college fund!!! Just enough to get him started!!!

People we are broke. I would suggest everyone accommodate themselves to the new fiscal realities coagulating around us. To continue to spend in the hopes that some future generation will pick up the bill is morally unconscionable. It is also contrary to our self interests by the way. As it is highly likely that the most damaging consequences of our financial mismanagement will develop in a more immediate time frame. That is, it is likely that you only THINK your kids will be the ones saddled with the consequences. In our current situation, it is far more probable that you will.

If a business enterprise requires government assistance to make it economically feasible then alarm bells should be going off in our heads with regard to the economic efficiency of that enterprise.

I wonder how this went.
if you want to run "hosted" mode, where the javascript and java is executed by eclipse, then yes, GWT requires eclipse.

GWT itself does not have a "desktop" mode, it does not have a "desktop" version, and so GWT apps cannot themselves be run as a "desktop" app unless you use the GWT Eclipse-basesd "hosted" mode - or you run the GWT-compiled javascript under Adobe AIR, Mozilla's Gecko / Spidermonkey, etc. etc. etc.
Right...

The debate is whether or not Tesla is more worthy of the money than another manufacturer. I'm not convinced they are.
