It is not 100% clear from the examples cited that scaling should necessitate the consistency issues they have. Surely it is quite straight forwards to scale user private data (i.e. 'sharding' on user data) such as position in play and the queue.

For the data which is cross user, such as that which drives their recommendation system (are there other parts, I don't know, not a user) then consistency would be compromised - but given the soft/heuristic nature, presumably also more or less irrelevant. Here eventual consistency would be good enough (and ideally should not require extra processes)?

Like the halting theorem, the implications of the CAP theorem are only unavoidable in pathological cases. Until it is identified as a pathological case then I believe it is premature to invoke such theorems.
Huh? I'm going to need more than hand waving to get that assertion. Please expand.

So you can buy a house in the south bay for $600K, using that as a baseline and a 6% Mortgage you're talking $3,500 house payment which is 60% -> 40% of your take home pay vs 100K -> 150K salary. Leaving you 2K -> 5k / month for other stuff. (car/insurance/phone/cable/utilities/food/etc).

'Average' salary for tech workers is $110K [1] so can you live on $2K/month?

I agree. If noSQL/SQL vendors start providing a common query mechanism for both SQL and coSQL, it will lead to huge adoption of noSQL products resulting in a huge transformational effect on data persistence.

No catch.

Our goal is to enable developers to build great apps that help make two-way and group video a part of the fabric of the web. Our focus for right now is on continuous improvement of the service that makes that possible.

We believe that there are reasonable ways for us to incorporate monetization in our overall product offering - while still keeping today's basic OpenTok service free. When it's time for us to introduce some of those enhancements, you'll know which ones those are.

Regardless, we fully expect that what's free today will stay free. No tricks. No catch.

Great post. However, with regard to Apple choosing certain dimensions for a tablet, it is probably patentable. The claim would cover a device with length, width and height within certain numerical ranges. Of course, the invention must be novel and non-obvious. If the ranges are specified too narrowly, the competitor can just make the device bigger or smaller. But if the range is specified too widely, it may include a prior art device, which would invalidate the claim.

Here's an interesting link on numerical ranges in nanotech patents:

I might be mistaken but I believe Sundar Pichai isn't an american national, in which case he'll be working on a visa. And in the US work visas require a public declaration of salary (the published data has the names stripped but frankly at a $50m salary I imagine he'd be easy to spot). So come paperwork renewal time we'll be able to see exactly how accurate TC are...
Not necessarily. Holding still is useful, but a modern submarine isn't dramatically louder when in motion than it is at rest.

Sound from turbulent flow over the surface of the hull is minor and doesn't travel very far (IIRC it's more of a problem for listening than being heard). More significant is the noise generated the formation and popping of bubbles on the surface of the propeller (cavitation) as it moves through the water. But this is a function of depth in addition to speed: to prevent cavitation you can just go deeper. Or more precisely: the deeper you go, the faster you can turn your propeller without cavitating.

Yeah I got an email today from elance(i've never used them) telling me they have thousands of web developer jobs that have only been bid on by a few people and they need more developers.

I've always been somewhat puzzled as to why NYC is the software development hub that it is. It's easy to get why the Bay area is such a powerful draw for developers. It's the one place in the continental U.S. where the climate is perpetually perfect, so it's only natural that people want to live there and it's inevitable that people with rare and valuable skills that can command high salaries will congregate there. It's not as clear to me what the draw is for NYC since the weather there is as bad or worse than Chicago, Detroit, Minneapolis, or Milwaukee and the cost of living is higher than those Midwestern cities. It seems like Boston should be a bigger software hub than NYC just on the basis of the proximity of MIT and Harvard and the intellectual community that fosters. On the basis of desirable climate (and astonishing natural beauty), it seems like Honolulu ought to be a major software hub, but it isn't. What's NYC's secret of success as a software hub?
This seems like one of the few cases where full on stealth mode makes sense, and even then, only if the team is slow and the work so far amounts to nothing more than an elevator pitch.

If the idea is something a bigger competitor would actually want, they are probably better off letting the team do the ground work, then either acquiring them outright or copying what they did. I would guess the biggest threats are from other motivated small teams that could execute the idea faster to achieve the aforementioned acquisition exit strategy.
Yes, that might work on some operating systems, but not on Windows XP (http://msdn.microsoft.com/en-us/windows/hardware/gg487503.as...)
There are some reasonable things here, but:

"Lumping together function pointers that operate on the same data structure is essentially object-oriented programming" is unbelievably contentious regardless of which of the various definitions of OOP you follow.
I hope they never find out about comic books. I hear there might be some illustrated violence in some of them now and again as well.
Perhaps it can be justified on the basis of property rights. If you own a penny, you have the right to place it on your table heads up or tails up, barring extreme circumstances. In that sense, the penny can be in two states.

If you own a six-sided die, you obviously have the right to place it in any of its six natural states.

If you own a hard disk, it has 2^N states, where N is the capacity in bits. You have the right to place the disk in any of those states.

According to this line of thought, any regulation which deprives the property owner of the right to place his property in one of its natural states is an infringement of property rights.

Agreed, in the same spirit, quality students do not need to graduate from IIT.
thanks for the prompt answer! could you explain the following from your terms (http://www.tokbox.com/legal/termsofservice):

1. tokbox reserves the right to put ads within the videos:

"TokBox retains the exclusive right to include and to sell advertising, promotions and sponsorships in the Service that is displayed on Your Websites"

2. also, if I create an opentok app, andd put ads in my website, I have to share the ad revenue with tokox:

"For example, you may sell sponsorships or branding in areas around the live video streams, provided that you and Tokbox agree in advance on appropriate compensation to be paid to TokBox."

in summary, in return for the free media service, tokbox can put ads in my app, and I have to share an unknown portion of the app revenue with tokbox, is this correct?

Skimming the comments, it seems a lot of people are missing a significant point - the employee is in customer service. Customer service is a dead-end job. It doesn't take long to get on top of your game, and there's really nowhere to go.

Managers and marketers get new products and changing business conditions to keep them interested, developers get new tech to explore and tech debt to resolve.

Customer service... is easy to master and once done there's no new fields to conquer. It's ultimately boring. Fine if you want a job to show up to and just do, but if you want to be interested in developing/advancing skills, it's not going to happen in customer service.

I actually find it a little insulting that the tone of the article is a little "well, the developers can handle 'not advancing', why can't the customer support person?".

The professional development tree for customer support looks like a stump.
Strange that the "refresh" button does not provide any visual feedback if there are no new messages. Not good. Even refreshing inbox by clicking on "Inbox" on the left briefly shows a "loading" message.

My assertion means that relational algebra without Cartesian product operator can be used for noSQL databases, except graph databases. Primitive operators of relational algebra such as projection, selection and set operators are pretty much scalable. Cartesian product is not. Authors mentioned that property of the Cartesian product in the example with WWW database. In order to emulate Cartesian product in noSQL developers have to use external tools such as Map Reduce which has nothing to do with databases. http://typicalprogrammer.com/?p=16
I don't see how. The only thing that prevents human intelligence explosion is limited intake rate of data (and possibly hardware, of which an AI's would presumably be more reliable).
I preferred when the refresh button was a link. It made sense because all of the buttons are actions to be performed (POST) whereas the refresh link simply checks for new emails (GET).

Hey no problem. I agree that the idea is to keep the discussion civil. I didn't mean for my statement to be troll-ish but I can see how it could be seen that way. But the downvote doesn't matter to me personally. I sprinkle up and down votes liberally as the mood strikes and I expect others to do the same. I don't think one needs to deeply think about each vote.
I would strongly disagree that it's contentious. (Think that over...disagreement about contention. I raised my eyebrow too.)

Some of the more exotic features of what people call "OOP", like polymorphism, take a bit more care and feeding to pull off in straight C. They are most certainly possible, that being said.

Unwind "OOP" to "working with objects that contain data and methods together," and structs with function pointers fit the bill. I've had people stand in my face and practically shout that C++ is object-oriented and C isn't, and one refused to believe or admit that C++ basically compiles down to C in the end.

Yes, there are a lot of third-party replication solutions for Postgres (http://wiki.postgresql.org/wiki/Replication,_Clustering,_and...), which offer various features (some of which offer even more complex and redundent replication options than the built-in replication). However, since they are all third-party solutions, there are such varying levels of complexity and support I think you would prefer to use the built-in versions of replication.

And as discussed in the post, I believe that streaming replication is a very nice replication solution, and probably good enough for most applications.
Consumers IME prefer the predictability that tiered plans offer. That is, many people would rather pay $40 for 400 minutes when they usually use 300 - 375 than $.11/min even though on average the PAYGO plan would be cheaper.

Any chance you can outline the steps in your workflow? Or perhaps provide a snapshot of example data?

I'm asking because I'm interested in real-world examples of how someone with a lot of CouchDB experience approaches a number crunching task like this. I think seeing the steps in how the data flows from instrument to final charts and graphs would be interesting. The fact that it was done in a rush makes it doubly interesting because it means that it wasn't planned out, and was probably iterated on a bit.
I have no problem with the Montessori method but if you're going to throw the names of a few very successful people as examples, you also need to show the full picture, i.e. for all these Montessori kids that became so successful, how many other successful people did not got to Montessori?

If anything, the fact that they only list 4-5 names tells me that at best, the kind of education you receive at that age is not that important after all (I think your parents and your environment are probably bigger factors) and at worst, the Montessori school doesn't really work that well after all.
It gets complicated the more things you want to be involved in. If you have no girlfriend/wife, no responsibilities, don't care what your few friends think of you and have no ambitions to add value to the world (other than through your startup) you can go hard, day or night.

For those of us who are married, have kids, do community work, go to Church (Sundays and weeknights) etc... we have a lot more to juggle and finding quality time is very difficult. You really need to put in at least 20 hours a week to have traction so it's a case of making time (and learning to live with less sleep). There's little to no room for procrastination for people in this boat.

Of course I'm not complaining - having a wife, family, helping the community and participating in a local church are great ways to add value with your life. It's all about priorities I guess...

I guess that's one of the reasons why successful startups are an anomaly.
Really cool idea! The homepage is immediately showing me sales around me. Will be using it more :)
Who are you kidding? We are all chasing money.
You really don't have to worry about competition until you get users/customers.

For the most part, people copy (or at least pay close attention to) what people buy/use.

Though, perhaps people prefer to be in stealth mode until they get some traction behind the scenes, to stave off embarrassment.

If that's the case, I think being in stealth mode serves a useful purpose.

Hey bigsassy, congratulations on launching! I saw your presentation at the Hacker News DC meetup last month and was impressed then as well as now.

I really like how you've set up easy feedback for those features that haven't been implemented yet ("how disappointed would you be"). This seems like a nice way to get some good feedback on how prospective users would rate different features even if they don't want to send you an email. It might be nice to add a simple textbox to that popup to allow for additional comments as well, at least optionally.

One minor nitpick - you spelled "dissapointed" wrong :)

I'm glad to see there's some forward motion on Gmail; it's seemed like development stalled out a year or so ago. However, it's a bit depressing. If it takes this long to get around to fixing the small things, how long is it going to take the fix the big things?

Gmail's still the best web-based email client I've seen, but at this rate not for long. There's a big honking opportunity here for someone to move in and eat Google's lunch.
