Capital expenditures are actually up over last quarter, to $72M. I don't see that as sustainable with a gross margin of only eight percent at twenty thousand cars a year, as that leaves a gross profit of only $120M a year at a $75K average selling price.

So something must be improved--either expenditures need to go down or gross margin needs to go up. Meanwhile, the average selling prices of Teslas will go down as early adopters run dry, even as R&D and capital expenditures on other models ramp up. At 25% gross margin, though, they can recoup their billion dollars in only three years.

If they're indeed flying in tires from the Czech Republic it sounds like there's a lot of low hanging fruit in the cost department, but it's quite possible Tesla has just built a more expensive car than they thought they were making. I suspect it, in fact. I'm not sure they'll be able to avoid going back to the public markets for more money this year if they want to expand their product line.

I think the interesting question is whether incumbent manufacturers will produce an equivalent auto lineup at less cost, or not. Many competitors, like Mercedes, BMW, or Ford, have existing labor, plants and tooling they could leverage for electric vehicle manufacture. Some have been in business for a hundred years. If the answer is no (market is too niche, existing plants are too old, incumbents lack the skillz) I think Tesla may be a viable entity. However, I think mainstream manufacturers have stayed away from aggressively creating new hotness in the vehicle market because they don't yet see any profits there. Their approach has been conservative, and I think the reason is that conditions are not yet ripe. Tesla was founded ten years ago; timing is everything.
In some cases, I can imagine that users paying for open source software would be a nightmare situation for the developers.

For instance, whenever I'm the sole developer of a "type 0" OSS project, supporting users is typically the most difficult part. This is because, many times, the software is something that I wanted for my own needs, and those needs have been met.

The one saving grace I often have in those situations is that, as demanding as some users might be, at least it's not the potential shitstorm of a user who has paid for something and isn't completely satisfied.

I even think carefully about offering a vector for donations these days. Because inevitably, it will eventually lead to a difficult to parse email from a user who wants help right now, because they just donated $2.
This is a tough question. To be completely honest, none of them are amazing. Opentable does a good job of telling us which guests are first-time diners, but I still have no way of knowing if they would have come in whether OT existed or not.

The biggest problem that a lot of restaurants face is that we simply don't know which marketing tactics are working. The only thing we see is if total revenue goes up or down. This causes us to just throw everything at the wall and guess what sticks based on revenue changes.

To some extent coupons work because we can simply track how many are redeemed, but like I mentioned in my original post, this cheapens the product often and causes the guest to perceive that the food is worth less than the normal price.

With that said, there is no homerun (at least that I know of) customer acquisition method as of right now.
Yeah, unfortunately you have to go in and manually export as BibTeX after every change to your reference library. It's not very annoying if you are writing one paper but I can see how that would be annoying if you're writing many at once. I suppose one could point LaTeX towards one master library in one location which you export to...
I'd prefer supporting its developers via Gittip or similar rather than having to deal with buying something to use it. That just puts a barrier on use. (If only they'd accept my money.)

Similarly, I'd rather share my open source project for free rather than spend my effort on selling it, and hope to get some support via other means.

I don't like barriers.

New York Times experimenting with link-bait headlines back in 1996.
I moved to the Bay Area in 2006 seeking out the very strong labor market. When I'm not situated for going through another risky startup, I want to be floating on a deep reservoir of high-paying employers desperate for every specialty I can conceivably claim. Nothing I've read convinces me NYC has that to the same extent yet, at least not when I don't want to become a quant. If you aren't here, you're selecting against people who responded to incentives I found very compelling.

It's the way numbers are written in India. 1,00,000 ( = 100,000 ) is 1 lakh and 1,00,00,000 ( = 10,000,000 ) is 1 crore. Millions and billions are not used a lot, but most people know what they are. See http://en.wikipedia.org/wiki/South_Asian_numbering_system
What does the PS4 announcement really mean?
That statement is disingenuous. Collateral based bad mortgages were a small fraction of the toxic assets. Banks only ended up forgiving around $20 billion in mortgage debt, which is nothing compare to the size of other issues. The bad mortgage issue has been a red herring from the beginning to distract attention from criminal fraud by bankers and absurdly focus on homeowners instead.

Almost all of the toxic assets, or more properly, speculative loss that will never be paid, was on the derivatives market which could be as much as $1.2 quadrillion dollars, 20 times the size of the entire world economy, of which even the $16 trillion in bailouts was a small amount.

The toxic assets have been moving around and ending up off of bank sheets and on federal government sheets as part of loan paybacks, which is more of the massive scam and stealth bailouts going on.

Every one of these mega banks should be dismantled. The same scams continue.

Expecting that is absolutely fine. Feeling entitled to that is not. You don't get to fuck over other people's days when they fail to extend you a courtesy.

Well I mean, clearly they do get to do that, but that is a problem, not excusable behavior.

I treat clerks nicely because I am a decent person. I treat government officials in positions of power over me nicely because, aside from being a decent person, I understand the score.

Frankly I wish American culture were such that I could just give people $50s instead of putting on the song and dance. Either one is bribery, neither particularly morally superior to the other.

This is what I thought when I saw the US custom of tipping bartenders.
I read this over, as well as the original blog post about the grails plugins and am not sure I can really agree. Personally I've always looked at open source contributions as a hobby, and in the end I'm doing it in order to keep the source open and available for those who wish to learn off of it / utilize it somehow.

In fact I would presume that the reason people are not going to pay up front is that they assume the developer is doing it as a favor to the community, and that giving them money for it would break the philosophy of giving out of free will. The real issue though seems to be an overall lack of resources. A one man shop, even with the ability to work on their projects full time, still has a maximum output capacity. Without others to assist there is the chance they would get swarmed with bugs and feature requests leading to burn out.

I think that open source developers need to step back and consider the costs and benefits of their projects. Doing a large amount of projects by oneself without a good job to support on the side will lead to burnout, as we've seen here. It may feel like bestowing a great gift on the community, but if you burn out and halt all development where has that feeling of contribution gone?

Which begs the question of which is more valuable: financial contributions or code contributions?
The form is being treated as a contract, and like all contracts I am requested to sign, I would line through and correct them as needed, then sign. If the other party will not allow the amendments, then we go to the next step, but in the mean time, the contract was made factually correct.

I did this with my girlfriend (now wife) on our first rental contract and was amused by her shock at my changing the "official" forms.

Likewise, forms with blanks that in no way allow for the information to be printed into the space given get writing that extends across whatever needed to supply the correct answers. Maybe the form will eventually be updated to be a little more accommodating, maybe not.

I know several doctors and they all complain about how they are getting screwed--by the trial lawyers, the insurance companies, the hospital, the government, etc.

This may just be a situation where the grass looks greener.
Another source says, "Believe me, my young friend, there is NOTHING--absolute nothing--half so much worth doing as simply messing about in boats..."

I believe this to be true at least for me, and I've also found that no other machine exists that can gather a family or friends together with the same reliable prospect for good times. A quality boat can last decades, but yes they are never any sort of good investment; they are an up-front and recurring cost. It just depends if it's your thing or not.
> I bet they understand a lot more about life than you do.

Dude, WTF?

I know this isn't a reply to me directly but here's an example of the sort of thing I had in mind. I have premature twins that were born last January three months early (they are doing great now, BTW). While they were in the hospital, family came and visited sporadically. One of our parents (I'll be vague) was with us in the hospital when my wife and I were mistakenly told by doctor that our son had potentially severe brain damage (IMMEDIATE PARENTHETICAL NOTE: he did not and is doing great, they misread the MRI). So, my wife and I are pretty alarmed and stressed.

The visiting parent, on the other hand, was stammering and incoherent for days afterwards, totally unable to handle it.

If we had been counting on him or her for emotional support, understanding, really anything at all of substance this meltdown would have been a problem. But we weren't, because, you know, we've known this parent for a while now and realize and accept his or her limitations. This response was unsurprising.

The point I was trying to make in my initial comment[1] is that, for some people, it is naive and dangerous to think of your parents as a "safe harbor" and you need to look elsewhere. Not everyone has all of the strengths and perspective that I can only assume your parents do. Mythologizing people as universally "knowing more about life than you do" because they're a little older is bullshit.

Or, just go with the flow. I remember a time I was leaving Boca Raton Florida, heading for Front Royal Virginia (field engineering work). I had a partial bottle of wine in my carry on (way before 9-11) and as I carefully set the bag on the conveyor for the x-ray device, I asked the security attendant if it was okay to have a partial bottle in the bag.

She said "What?" in a heavy accent, so I asked again, she said "What?" again, and by this time my bag was at the bottom of the exit ramp of the conveyor.

I said "Never mind, have a nice day" picked up my bag and made my flight.
God, I wish it was the way you describe it. Unfortunately, Mr. Incredible is the exception, not the rule. Most flunkies really don't care about the person in front of them - at least not enough to risk their job (which Mr. Incredible was doing every time he helped someone).

Additionally, it has been my experience that American cops are not shy about showing overwhelming force. Nor are they shy about pushing the boundaries of what they can do to you, what they can cite or arrest you for. Nor do they have any compunction about tricking you into giving them more access or more information than they have a right to.

We live in a society which has somehow learned to ascribe to the philosophy that you should use your power to it's full extent. Discretion is a sucker's game. The MO is: show up to the scene with overwhelming force, and if anyone gives you an excuse, arrest them. Cite them. Take their stuff. Cost them time and money. Punish them. Or, for a federal prosecutor: ignore common sense and threaten a non-violent person with decades in federal prison to get your desired plea-deal. There is no prize for discretion, only convictions.

15 years ago, downtown St. Louis was largely vacant except for a few big name companies. Since then it's come back in a big way, with a solid loft district, new sports and entertainment facilities, and a steady progression of rehabbing and revitalization.

But there's still a number of large buildings waiting to be rehabbed. The Railway Exchange is the biggest of these (but at least it's partially occupied!)

One of the best (and first) success stories is the City Museum:

There are dozens of such projects now, all of them 1 or 2% different from the others, little differences that would be more suitable as plugins or extensions to a defacto static generator (Jekyll).

Instead we get a mass duplication of effort into implementing essentially the same thing, a common problem with open source projects.

What is really required is a dead-simple static generator, the equivalent to what Wordpress and Movable Type did for the old style of blogging. A simple app that ordinary computer users can plug their FTP or S3 details into and then publish.
Our facility manager wouldn't like that ;-)
I read it slightly differently.

Virtually no open source project makes it big without some kind of full time commitment and/or corporate patronage.

However, there also isn't really any incubation mechanism in place for OSS. It sort of grows organically or it fades into obscurity, and that's not necessarily an optimal model.

The solution being that financial contributions early on might inject energy into a project which might otherwise lose steam. It makes sense to me. We've probably lost at least a few cool projects to atrophy-and-entropy land, which is a shame.

For me, the good thing about Play is the platform support. Play 2.X is fully supported on Heroku which makes developers to hack something out really quickly.
He misses out on another type of open source project: those supported by professionals as part of their day job, but that aren't directly related the core business of the company.

For example, at my current job we need plupload, or something like it. If it didn't exist, we would be forced to create and maintain something like it. There's no reason why we wouldn't release the code as open source and then continue maintaining it as necessary for our software. The company wins, and so does everyone else.

Well you have to consider that:

* CBs are monetizing enormously; and if they stop the stock market crashes; they are also promising inflation;

* the Libor conspiracy might bring down one TBTF in London

* Bankia and Santander are under stress and might fail

* There's a full-blown currency war going on with competitive devaluations

* People are placing billions of dollars betting that the Japanese bonds & yen will collapse

* there are reasons Germany is repatriating their gold

I could go on, but bitcoin is oblivious to all that; in some ways it is less risky than the int'l banking system.

Finally, just as an example, the Fed is printing $800,000 new usds per each new bitcoin created. I'm not saying that bitcoin is going to be that valuable, of course, but if you look at the numbers involved you might as well consider putting some savings completely out of an interconnected banking system that is the contrary of the internet: it needs all nodes to be up and running to survive.
This is great, good job!
Would Google Glass be able to solve this type of issues???
I concur, what is done is a step in the right direction. Once its digitized even scanned copies can be transcribed via some technology(may be OCR?) in the future if not now.
This approach seems to have worked for Google, at any rate.

As in many other situations, simply setting boundaries is often enough. In this case, user expectations.

Has the OP used J, how long, any experiences. I heard of J several years back, has it picked up at all ?

I'm really surprised that nobody is doing a kickstarter thing for open source.

I mean in all honesty if I saw a link to some awesome fucking shit and I saw that it was $500 away from being open source, I'd probably do it. It would probably happen yearly or less, but honestly there are a lot of developers making big bucks and we all know how much certain tools could make our lives so much easier.

So Padlet's sort of the Weebly approach to collaboration? I like the idea, though I think it could use more structural elements (only having free-form text squares seems somewhat limiting).

If someone makes it to graduate school without knowing LaTeX, I would suspect chances are high they don't really have any interest in changing their routine then. They're busy, and hey, word has been working in university for several years already!

If I wanted to increase LaTeX adoption, I would get undergrads hooked on it. I bailed to LaTeX my second year of undergrad and never looked back. Even with papers for the english department it was great, if only because it just looked that much better than all the Word formatted papers from my peers. The fact that it made bibliographies dead simple was just icing on the cake, it practically felt like cheating. Get undergraduates to understand those "sly" benefits and they'll be willing to take a night off from binge drinking to learn it. At least more willing than a grad student anyway.
