Well in sweden (which is to supposed to be a peaceful nation) there are city districts where the police can't go because the "natives" try to kill them.
Unsurprisingly these places are full of immigrants.
You can pooh-pooh over how they have lousy conditions and are poor and riot because of that, but the fact is that they get everything they need from the state (food, shelter, spending money, schooling, healthcare), and also there has always been poor people in sweden and they haven't had problems with eg. cops or looting and rioting.
So it's probably some kind of cultural thing for people from some places.
You are correct—photons do not have mass, and they are affected by gravity. The analogy here confounds things because it suggests gravity is part of the picture, when it is irrelevant to the explanation (example of another confounded analogy: https://xkcd.com/895/). Photons are affected by gravity because gravity affects space-time. Photons travel in straight lines, and the presence of mass changes what a straight line is. Figure out how this is connected to the Higgs and you've solved the biggest problem in physics.
nowhere in the article there is any mention of gravity. mass is 'just' a form of energy and photons definitely have energy; in general relativity, that's enough. we don't have an accepted theory that works on quantum scales.
Gotta agree. But people apparently need a Hero and hero worship to get exited about things (ie. funding).
I bet there are thousands of people who would have been able and willing to do the same things as Neil, and who today would happily make a one way trip to Mars.
Most people of course couldn't be bothered to get off their couch, so these people (eg. asttronauts) of course get my respect for pushing the envelope.
So, do you actually know anything about Neil's life, and are dismissing all of those accomplishments, or are you making that statement out of complete ignorance? He didn't pop out of a test tube and into the Eagle, and sure, lets say thousands of people were equally qualified. That's about 0.00002% of of the population, and puts him in the top 0.1% of the people that could have done what he did (i.e. he did it).
What an amazing amount of money. Apparently they have got $70m+ in total.
Our small/mid sized company with about 20 employees could operate for about 50 years with that amount of cash...
An apparently they already pay for themselves:
"“Business is fantastic,” 10gen President Max Schireson told me. “We keep outperforming every goal that we set for ourselves and the market just feels like it’s huge.” In fact, he said, new sales people pay for themselves almost immediately upon joining the company."
So I wonder what they are going to do with that huge pile of cash? R&D for a single DB surely can't be that expensive (or at least it would be difficult to get that many people to suddenly work on productive things that would actually improve the product and not just make it bloatware).
Apparently the hype works, for a DB that is about scaling but doesn't scale yet? "Just another $100m and we'll get there"?
How many people actually need a DB that "scales" better than mysql/postgres which are much easier to use and better supported and understood?
" Among other things, it has been criticized for being rather difficult to manage at scale. This is somewhat ironic, as scalability, along with the flexibility that comes with being schemaless, is among the driving factors behind the NoSQL movement. One would expect the most-popular of the bunch to scale with ease."
disclaimer: I used to work for Couchbase, and am still involved in the CouchDB community
'Magic Scaling' isnt the only reason people use alternative data stores such as Mongo (or Couch), in fact as shown it can often turn out to be a really bad idea to do so. I wouldnt still be interested in CouchDB if it was just 'do stuff a bit differently from mysql and everything will work at scale' type database.
Schemaless, Native JSON, master master replication, HTTP API are all features which can be hugely beneficial to particular applications over tradition RDBMS' (those were only a few features and they were probably bias towards CouchDB because I know that better)
I think your post proves the theory that they have a lot of product education work to do.
It's not just about scaling. IMO it's about teaching the vast armies of software developers that work on proprietary line-of-business software that there is variety in data stores and that they should be using the right tool for the job.
I shudder to think about how many EAV anti-patterns have been implemented on top of relational databases. Or how many 1-table-per-X databases there are. Or how many "json" columns and "blob" columns and "xml" columns have been added to otherwise innocent tables who did not deserve that kind of abuse.
That alone -- educating and giving tools and support to engineers outside of the tech industry -- is no easy task.
You'd be surprised, "scaling" a database is something that more and more folks are having to do lately, with the onslaught of mobile apps and facebook apps and web apps, it's just a whole lot easier to create an application that gets hundreds of thousands of users - millions of users.
And more importantly, you can have an application that has hundreds of thousands of users and not really make a ton of money, so you kinda need something that is easy to use because you don't have the capital
Thanks for all the replies. I wasn't actually trying to put mongodb (or nosql in general) down, there sure is a use for these technologies.
The amount of money just seems staggering (money in the IT world nowadays seems to be off the charts, re. facebook et. al.), and it probably will be hard to put it all to productive use. But it will of course also help to improve the product so no worries :)
And indeed, I do have a relational database with a column that stores json! The horrors :)
You could help me get familiar with mongodb, any good real world tutorials for it? I have played with it just a little.
I've seen these kind of people, and the fact is that they are not "the fun of the party" though they themselves of course can enjoy themselves (and the drunk people don't mind).
It's the "drunken" people providing all the fun and atmosphere (no, you don't have to be wasted, just a little drunk so that you don't have so many inhibitions).
Well DRM helps nothing to stop a video from being torrented, so why bother with it.
I think Louis CK is smart enough to understand this, and with this personal appeal will probably sell better than using the usual methods.
I bought a copy because of this. It's nice to support the artist directly especially when the video file finally is as good as the versions you usually find only on torrent sites (no "you criminal" warnings eg. like on store bought DVD:s. Nice way to thank those that have actually paid for the content...).
