Re: Secular Stagnation: GDP is the Wrong KPI - http://continuations.com/post...
"Thanks for the link, that's very interesting." - David Semeria
Re: Secular Stagnation: GDP is the Wrong KPI - http://continuations.com/post...
"We could take a weighted basket approach, similar to CPI. Here's a quick example (without weights) off the top of my head: - Average life expectancy - Average time spent commuting - Average time spent on recreation - Net savings/debt (excluding mortgages) - Access to education (places available) - Cost of education - etc... It would be fun to crowd source this list - and I know just the tool for job :-)" - David Semeria
Re: Secular Stagnation: GDP is the Wrong KPI - http://continuations.com/post...
"I think most people would agree that GDP is too one dimensional to accurately capture variations in aggregate value added (in the widest possible sense of the term). The key question is what do you replace it with? A good KPI (or composite KPI) must be easy to compile and, importantly, allow for backwards projection. We need something like The Economist's Big Mac Index for PPP." - David Semeria

"The official site is the best place to start: https://spark.apache.org/ If I had to bet on one OSS project for the future, it would be Spark." - David Semeria
Re: Code Execution: Where Are the Clouds Headed? - http://continuations.com/post...
"Yup, the difference is quite subtle. They key is the DB service (since the others are stateless which makes them much easier to manage). That's why I'm very interested in Spark, because it's DB agnostic and scales painlessly." - David Semeria

"I think Albert is talking about much higher levels of abstraction than those offered by, for example, Heroku. Imagine a multi node elastic infrastructure that is configurable from a single web interface. Rather than providing multiple (linux) instances which need to be manually maintained, the infrastructure would expose, and you would program against, a set of high level services. How these services are implemented and maintained ceases to be a concern for you. The key point is that they are always available and can scale with your needs." - David Semeria

"At the moment we are digging deep into Spark and keeping our eye on Mesos. We run Spark on our own hardware, as per my original comment. I suspect we'll soon see layers like http://mesosphere.com/ being offered as a service. At that point, assuming the delta is not too larger with respect to DIY, I think such services will be very successful because the dev ops workload falls off a cliff." - David Semeria
Re: Code Execution: Where Are the Clouds Headed? - http://continuations.com/post...
"I think I answered that: Spark running on top of Mesos." - David Semeria
Re: Code Execution: Where Are the Clouds Headed? - http://continuations.com/post...
"In my experience there's not significantly less dev-op work involved in maintaining a cloud server compared to one running on dedicated hardware. However, the larger the instance the more cost effective it becomes to buy your own hardware. For this reason we run small instances ( <= 8GB RAM) in the cloud and anything larger on our own hardware. For the larger instances (eg 64GB RAM w/ SSD) the payback period for the hardware is around 3 months (excluding power and bandwidth). As yet we have not begun experimenting with data warehouses because we don't think the technology is mature enough. When it is, this could well be a game changer because it abstracts away the database and everything underneath - which WOULD lead to much less dev ops work. I think Spark and Mesos will play a strong role in this shift." - David Semeria

"I see the discussion has moved on from "we must know what we're fighting for rather than what we're fighting against" to the more complex issue of the causes of terrorism. I'm not going to get into that, but I will add one thing: as far as I'm aware, no two democracies have ever gone to war with each other. That's why I believe three interlinked preconditions are necessary for change: universal access to basic education, a free press, and fair elections." - David Semeria

"Agreed, that section highlighted ideas that were new to me. Could Surkov's alleged strategy be a reaction to the proliferation of information sources which are now available? If it becomes harder to control the mouthpeice then it makes sense to move down a level and interfere directly with the very notion of reality. I'm reminded of Barry Schwartz's TED talk on the paradox of choice." - David Semeria

"You're projecting your happiness onto the rest of the Western world Andy. Would you be so cheerful if you were unemployed and saddled with debt?" - David Semeria
Re: The Charlie Hebdo Massacre: We Need a Coherent Alternative Idea - http://continuations.com/post...
"A very good Arabic friend explained to me the role economics plays in all this. Simplifying greatly, his thesis is as follows: money => education => critical analysis. He points out that in the West we are much more cynical than in poorer countries, which leads us to be distrusting of figures of authority. It may be somewhat tenuous, but I think there might be a link between your ideas regarding UBI and the fact that poverty provides fertile ground for radicalism." - David Semeria

Re: Some Thoughts On Workplace Diversity - http://avc.com/2015...
"I'm glad you made that point Fred. I know it's uncool to say so, but I firmly believe the problem is supply side, not demand side. Like Andy Swan, my policy is to hire on merit alone. If that means my team is not diverse, so be it. My first duty is to my shareholders, no apologies given. The best solutions tackle causes, not effects. Hiring the wrong people just to promote diversity is tackling the effect. Getting kids interested in STEM is tackling the cause. Enlightened and motivated STEM teachers is definitely the game changer IMO." - David Semeria

Re: What’s Next - http://avc.com/2014...
"I'll go out on a limb and mention Gestalt, which basically means the whole is worth more than the sum of the parts. I'm talking about how information and services are organized, especially on mobile. A great example is Wikipedia -- the site itself is worth more than the sum of the pages, because the pages are enhanced by their presence on the site (indexing, hyperlinks, etc). I believe we'll see a big change in how stuff is organized on mobile. I see city apps emerging that aggregate many external services that are relevant only to the city you are living in (or visiting). I see personal apps, that aggregate personal information about "me" -- well being, medical records, tax deadlines, etc It's not just about ease of access, it's about the synergies between different services related by context." - David Semeria

"Thanks for the link Albert, I was not aware of Laplace's Demon. I arrived at this conclusion just by thinking about the problem for a few days. For me at least, it's an acceptable rebuttal of the no free will argument." - David Semeria
Re: Free Will (Revisited) - http://continuations.com/post...
"I spent a great deal of time thinking about this subject the last time you wrote about it. My thinking led me to a hypothetical situation where I would ask a person to make a choice and then, before they answered, I would inform them of their choice based on the deterministic state of the universe at that point in time -- a state which also included the communication of the choice. I then wondered what was stopping that person from changing their mind. That is when I ceased worrying about free will." - David Semeria
