Could someone please explain the business model of such open source based startups in general?

There are a few different models: for example, "open core" where part of the overall product is open source, and then layers of proprietary stuff are put on top and the aggregated "thing" is sold (but can't be redistributed). Then you have "dual licensing" where the product is purely under a F/OSS license (often times the GPL or another "copyleft" license) and the company sells commercial licenses that offer different terms (such as the right to redistribute a derivative product without needing to make your own product F/OSS).

And then there are the "pure play" OSS firms... everything is F/OSS, but they test/certify certain builds, and ship binaries for money even though you can download something which is probably 99.999% bit identical (images and copyright notices being the main differences). In this model what the customer is paying for is - arguably - not software at all, but "peace of mind," indemnification, certification, the "somebody to sue" factor, support, etc. Red Hat are a good example of this latter model. JBoss binaries are freely available, and CentOS is nearly identical to RHEL, but yet people still pay Red Hat for JBoss and RHEL.

In all three cases, there are also supplemental things the firm can sell for revenue, such as training classes, certifications, professional services work, T-shirts, etc.

There are probably still some other variations that I'm forgetting at the moment, but I think those are the big three.

Hey, Engadget comments called, they want you back.
> You're not really a scientist if you create something that works and you don't really know why.

According to your logic, the only true "science" is mathematics. If you test the workings of your "creation" using scientific method, you're still a scientist. Scientific method is also about testing your claims empirically, and it has been successfully applied for more than a century to study of biological organisms, climate, and other complex systems that we do not "really" understand. Not to berate understanding of underlying mechanism which is always preferable, just to point out that there is more than one way to skin the cat.

That's not an assumption. You can clearly see the brakes in the video which shows the intended use.

If it's single gear, you can simply stop pedaling to brake since it would be direct drive. In fact, that would probably be the easiest as I doubt this bike is capable of any serious speed.
It's a fixie. The front brake doesn't ever need to be used.
Not necessarily. The costly part of recycling is separating materials.
If this has cardboard with a waterproof coating or plastic skin (as it appears) or is glued to other components like the rubber tires then it could be very expensive to process. And at the end you are left with almost worthless cardboard.

An aluminium or steel bike is recycled in exactly the same way as a car - and we have got very good at that process - and at the end you have valuable scrap aluminium.
7zip is a slow compressor that compresses well. fastlz should better be compared to LZ4 or Snappy which are meant to be trade compression rate for speed.
The Search API's limits are more fluid than the REST API. It generally allows for about 1 query per second.
No matter what else happens in the world, the core team will be able to focus entirely on Meteor for several years, without taking on consulting work or trying to create some other application on top of Meteor to sell

Does that raise any red flags for anybody?

Do development frameworks built for their own sake ever really work in the wild?

I think of successful ways to build web apps, and the names that spring to mind are rails, django, php, etc. that evolved by developers who were using them to build stuff. In some cases (rails, django especially), they were the side product of a single application.

I think of overarchitected nightmares such as Fusebox and some of the magic frameworks that would be Meteor's competition, and they tend to share the quality of having been built as the Ultimate Solution to Everybody's problem (with the conspicuous exception of the developers themselves, who aren't actually dogfooding it for anything).

To be clear, I'm impressed by Meteor and I'm looking forward to seeing where it goes. But it makes me a bit uncomfortable to see a declaration like "we're definitely not going to try building anything with it!" tacked onto their funding announcement.

Or Jim Dalrymple, who in my opinion, took the on the role of official Apple apologist for the 5by5 Network when Gruber left.

He also has much more to say on entrepreneurship (given his first-hand experience with the App Store).

He was also the lead developer behind Tumblr during its rise, which I imagine involved some entrepreneurial thinking.

I'm sure you could use the actual drive chain (it looks like a cogged belt) to slow the vehicle down by removing energy from the rear wheel. My guess is that the front brake is only used for emergencies, and the bike works as a fixed-gear.

Man, $39 seems like a terrible price point for that. Forty bucks is a really good price for a well-designed, full-color hardcover book, not an e-book. $10 and I would've bought it already, but now I'm just queuing it up on Goodreads to maybe buy at some point in future.

For me the benefit of a cheap bike is that it then becomes disposable, meaning that no one wants to steal it and even if they did it would be no skin off your back.

Amsterdam has this problem solved in an interesting way. I am told there is a ring of drug addicts that steal and resell bikes for a living. You buy a bike from them for 8-10 euro, ride it around for a couple months until it gets stolen, then buy another stolen bike to replace it and repeat the cycle.
You're taking this way too seriously. Please, read the review. My interpretation is that it's Marco poking fun at Siracusa.

If it could somehow use standard off the shelf packages rather than 'Smart Packages' then we'd really be cooking.
Wide open DB access is for rapid development. In production, which meteor is totally not ready for yet, you'd restrict the db, have proper auth(which isn't built into meteor yet), and call restful methods from the client that have both client side and server side validations.

You are being way too vague. What is setting your expectations of "slowly"? What rate would you expect children to learn language at? Even if that were to be the case, your argument is essentially a god of the gaps argument. Not P therefor Q is not sound reasoning.

The whole notion of the Universal Grammar and innate language faculties which instantiate subsets of the Universal Grammar is weird.
If you listen to Marco's podcast, he'll occasionally say something like "I want to talk about this topic but Siracusa just talked about it on his podcast and did a great job so I'll be quick about it."

It think this review-review is Marco's way of saying that he knows he's expected to comment on the new OSX and everyone should just go read Siracusa's review. Plus it was funny.

I still can't believe the 'skeuomorphic' interfaces for Calendar and Reminders made it into the final version of Mountain Lion.

This is one of those rare moments in intellectual life where being in the room and now seeing the debate develop, it becomes clear that the resulting hype isn't (wasn't) loud enough.

This distinction marks the real turning point in AI from abstract, grand claims with highly restrictive evidence toward engineering that simply works. Who cares about the ontology when we can recreate? It's like saying airplanes don't properly explain flight because they don't replicate how birds do it. Who cares? We can fly (and translate and soon reason) artificially.

It's clear that Chomsky and Universal Syntax has held back the entire field of AI (and at MIT). There isn't one algorithm in the human mind to decode all of our mental capabilities. That's mistaking subjectivity for objective lessons. Trying to recreate that Phantom has led to rule tables in AI, constraints on how the mind must operate. Instead, by allowing those fuzzy boundaries to accumulate with evidence, statistical approaches win in the long-term of our lives and in this debate.

Yeah so, I suck profoundly at web application security, even on your everyday vanilla CRUD app. Having all of this logic available on the client needs tptacek approval before I will go anywhere near it.

Then again, I'm quite technologically conservative. I'm sure this is very exciting for early adopters but I'm not going to put any time into it until I know I can build something useful with it.
Ah, so I should set "Vary: Accept". Thanks, that was a great help.
The analysis is all nice and dandy, except for being wrong. Interrupted reads are retried, but only up to a certain amount which can be changed. The (perhaps not so good) default is to retry one time.
Indeed for in-memory decompression LZ4 is much faster as expected:

>I don't think Microsoft can reasonably compete with Apple in the hardware game. Apple's too good, and they have too much practice.

MS is good at hardware but the problem is margins and the lack of proper leadership. Apple has been building this manufacturing advantage for a decade and can get a cheaper price because of their high volumes of their orders. It doesn't hurt to have essentially created three new markets as well during that span.

>But I do think with the low price point of Windows 8, they realize that there is less and less money to be made in the consumer OS space, and more potential money to be made in servers and services.

I'd also add that Apple and Google are both splitting the PC market with tablets which means even far less future revenues from Windows.
As someone who's fairly ambivalent with respect to Apple, Daring Fireball is really good when Gruber is writing in-depth about Apple. It's from a certain perspective, but it's definitely insightful.

Sadly, he's utterly vapid and agenda-driven when talking about Android and Google, or writing snarky one-liners responding to criticism of Apple. I'd love to get a feed of Daring Fireball with just the longer pieces.

I apologize for my english. I am starting a new project. The problem (if it is a problem), is that it is based on external APIs. It has a lot of own technology, which is taking a lot of effort to develop. My fear is, what happen if those APIs become unavailable?

Have you got any advice for this kind of product, which are based mainly in data provided by external APIs?

Thank you!

"The previous post assumes the reader is familiar with the notion of undefined behavior and how C compilers have started to justify their more aggressive optimizations along the lines of “this program has always been undefined”....

This was not a serious suggestion, but should be understood as an argument in the debate about the exploitation of undefined behavior in compiler optimization.... I was not suggesting to replace the respected restrict keyword with an awkward replacement. All the arguments I put forward were in bad faith."

> If Microsoft wants to sell hardware,...

Microsoft does not want to sell hardware, not in the way you imply. Surface is akin to Google's Nexus; a 'northstar' product intended to lead OEMs in the right direction.

Microsoft is not, and never will be, a hardware company. Please don't go off saying "what about Xbox or mice & keyboards".

First Xbox, while finally turning a profit, is a shining example of how far Microsoft needs to go to truly be excellent at hardware supply chain management. The RROD debacle cost MS many $B and there is no evidence that they have truly learned.

I know the people who drove the Xbox360 hardware design and supply chain management. They are now war scared seasoned experts. The type of people you want working on the next big thing. None of them even knew about Surface until it was announced. Typical Microsoft organizational silos.

Designing and building hardware is easy. Easy relative to SELLING hardware. Retail, hardware supply chain management, support, etc... are huge endeavors that Microsoft has very little capability for. The DNA of Microsoft is that of a software company.

Second, a tiny, tiny percentage of Microsoft's profits come from direct sales of products to consumers. Like less than 5%. In order for MS to seriously get into the hardware business it would need a model that enabled something close to the +40% gross profit margins Apple is seeing from its vertically oriented model. It would take a decade or more of radical change for Microsoft to make such a change, and while MS has demonstrated it can turn the ship (more like a fleet) before, I simply do not think this is a direction it can go.

I do not believe Microsoft will try to compete with Apple on Apple's terms (vertically integrated, high-margin hardware with up-front payment). I believe Microsoft will try to end-around Apple by continuing with a predominantly horizontal play, enabling annuity revenue streams from 'experiences' delivered across all of a user's devices, regardless of whether they run Windows or not (including Apple's devices).

I'm going out on a limb because I don't really know much about neurology & I may be wrong about facts but.. I think an issue here is that we don't really know what "natural intelligence" is.

For a significant part of the Scientific age we knew about genes in some sense without knowing much about them. We called them traits, observed & measured them. We got to know some "rules" about their inheritance. But it wasn't until genetics got to be a little better understood that we got to know their physical manifestation. We can explain the diference between genetic & cultural (memetic?) inheritance in these terms. A descendant's cooking habits are memetic and her hair colour is genetic.

When it comes to neuroscience I think we're where we were a century ago in biology. Emotions, thoughts, memories. We don't know what their physical manifestation is. We dont know how they work. Since we don't know much about how natural intelligence works I think our common sense definition of intelligence is, to a certain extent: "stuff we can do that computers can't."

I think that if we had a definition that was more functional than observational, you wouldn't be hesitant at all to use "mammalian" in your definition. Whatever processes result in observed human intelligence are almost certainly shared with other species. We'd probably also know what species to draw the lines at: reptiles? invertebrates? fungi?

If apes have intelligence, goldfish don't but octopi do that suggests there multiple versions of natural intelligence.

If you are bound for a trip in Malaysia and yet to figure a way how to reach your hotel from the airport, taxis serve as a good resort.

You can choose to ride a taxi Malaysia from the Kuala Lumpur International Airport, but remember that you cannot just hop into any cab that you will find. You have to go first to the ticket window or counter, fall in line, and inform the assistant where you are heading to.
