Re: Code Execution: Where Are the Clouds Headed? - http://continuations.com/post...
"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

"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

"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

"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

"A bit of trivia: Bob Geldof uses an old Nokia 6210 (he calls it the AK-47 of mobile phones). The ringer is broken so if you want to call him you need to text him first and ask him to stare at the screen so he can see the incoming call." - 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

Re: The Grind vs The Pivot - http://avc.com/2014...
"Arnold is the only adviser to the company. My reasoning was a bit like for programmers: one great one is worth 10 average ones. He provides us with very valuable feedback and guidance on product, marketing and communication. The geographical distance is not really a problem (because Arnold always pops in to see us when he's in Europe). The time difference is more of an issue: it's hard to take someone seriously when they Skype in their PJs :) Arnold is a gem." - David Semeria

"First point: yes, they're teaching the kids to be users, not programmers. Your second point is very similar to how the mouse will work. One kid will be the mouse and every time the user moves the mouse, the mouse kid will call the OS kid and say "mouse has moved up a bit and left a bit". The OS kid will then call the screen kid (at the blackboard) and say "move the pointer up and to the left" and finally the screen kid will call the pointer kid (with a big pointer on a stick) who will actually move the pointer." - David Semeria

"It's more a question of explaining the most important principle in computing: abstraction -- ie the fact that a given layer can only communicate with those immediately above and below. I was thinking of explaining this principle using 3 kids with telephones. Kid A can only talk to kid C by asking kid B (who is contact with both) to pass on the message, Except that instead of phones I want to use bananas." - David Semeria

Re: Attention All Software Engineers: Please Volunteer During The Hour Of Code - http://avc.com/2014...
"Here in Italy my 11 year old son has just started learning about IT at school. I read his text book and became depressed. It's full of things like "How to use in start button in Windows". He has learned that stuff by himself, thorough trial and error. What is missing is any notion of what a computer is and how it works. So I proposed to his teacher that I came in and explained. But not using a blackboard, I wanted to something different which would hold their attention. So we're going to build a computer out of students. Each one will wear a hat defining his or her function (RAM, OS, keyboard, etc) and they will hold colored ropes which will define the communication channels (red for output, green for input). We'll then run a program on our human computer (I was thinking of tic-tac-toe or Connect 4). I don't know if the experiment will work, but at least we'll have some fun." - David Semeria
