Is there anybody here who has run MongoDB at moderate scale with good results?

As in a few terabytes of data, >10k ops/second territory.

I've been really disappointed with its reliability and performance in situations where I've been around that.

Has anyone had some good experiences with Spark?

I put several weeks in to moving our machine learning pipeline over to Spark only to find I kept hitting a race condition in their scheduler.

After doing a bit of searching, it seems this is actually a known issue https://issues.apache.org/jira/browse/SPARK-4454 and there's been a fix on their github for a while: https://github.com/apache/spark/pull/3345 and yet in that time two releases have swung by bringing a tonne of features.

I ended up having to drop Spark ultimately because I wasn't confident about putting it in to production (the random OOMs and NPEs during development weren't great either). Does anyone have any positive experiences?

Very interesting.. Do tell. What kind of misconceptions are there and how have they changed?

I still labour under the assumption that NREs make doing anything like that _extremely_ expensive.

The problem with the Monument Valley numbers is that they expected a hit game on iOS would magically translate in to a hit game on Android and that's really not the case.

The two stores are completely separate, your popularity on either will not help you on the latter unless you're bringing a big marketing budget with you or have something truly unique and viral.

There are plenty of popular Android games that have virtually no player base on iOS.

To be fair, the market put such a small premium on the non-Alibaba value in Yahoo largely because they weren't confident that Yahoo wouldn't just squander it.

Yahoo's purchase of Tumblr for nearly a billion dollars is a great example. That asset will likely never give Yahoo a return.

Over 10,000 people died in drink driving incidents in the US along last year. Distraction from mobile phones also led to thousands of accidents, should they be illegal too?

Let's now throw the baby out with the bathwater.

Just as another datapoint, I used to keep a couple of virtual machines at Linode.

After seeing how they acted after their security breaches, I left for DigitalOcean. I've also recommended DO over Linode to other people for that reason.

I should note it wasn't the fact they had a security incident, that happens. It was the way they 'communicated' it.

I see the latter case used as an argument lots but I just don't seem to understand it.

OVH will rent you servers for as little as a month at a time, for a _massive_ reduction in cost over AWS. We're talking >10x. Are there really startups that only have capital to last a week?

Presumably those were a while back?

Do you think the climate has changed since then to make it much harder?

"Although your product may not be very appealing yet, if you're a startup your programmers will often be way better than the ones your customers have or can hire."

Is this really true? I'm very sceptical.

Does anyone have any evidence to back this up?

The reference to the unmanned large planes at the bottom:

"Mr McAuslan said there was an urgent need for rules to be tightened before much larger unmanned cargo planes - potentially the size of a Boeing 737 - took to the skies."

sounds intriguing. Are we really close to that happening? I was under the impression the CAA restrictions around unmanned aircraft were still very tight.

That's because this was never about Microsoft investing in the Nook.

Microsoft's investment was really just a settlement with Barnes and Noble in everything other than name.

Microsoft sued B&N (http://www.bbc.co.uk/news/business-12814018) for infringing on the patents it's been collecting royalties from Android manufacturers for. B&N then counter-sued (http://www.phonearena.com/news/Barnes---Noble-countersues-Mi...).

Once Microsoft invested in the Nook business, the whole thing got dropped. Makes you wonder if Microsoft were concerned that B&N actually putting up a fight might bring the whole of their lucrative Android licensing business in jeopardy.
