"And then there are those texts that are unintelligible even after decryption ;-)" - David Semeria

"The big breakthrough came with the invention of asymmetric (or public key) cryptography (link). To communicate securely, both parties needed to know a "shared secret" which is used to encrypt the messages. This raised the paradoxical question of "how do I securely communicate a shared secret with somebody over an unsecure network?" Asymmetric cryptography is the answer, and it's actually very easy to understand. I send you a small metal box which contains an open padlock. You put the secret to be shared inside the box and then close it with the padlock and sent the box back to me. Since I'm the only person with the key to the padlock, only I can see inside the box. Voilà! We have managed to securely share a secret over an unsecure network. In this analogy, the metal box is the public key and the padlock key is the private key. This is why exposing your private key (or having it cracked) is such a big deal. If that happens anyone can look inside the box. Once the shared secret is..." - David Semeria

"What makes it inherently harder to innovate? Two things: - The low hanging fruit has already been picked (apart from games) - The "rich-get-richer" dynamic mentioned by Chris, making it harder for new entrants to get a toe-hold in native apps." - David Semeria

"The winner will be the one which comes up with an consistent and intuitive framework for presenting the information. People will not want to learn a new interface for each city app -- they will want everything to be in the same place. I believe this is the key reason why Facebook beat my MySpace." - David Semeria

Re: The Mobile Downturn - http://avc.com/2014...
"I would hate to be in a startup whose objective was to either be on the mobile home page or be an "always open" tab in the browser. I think there is more chance of winning the lottery than achieving these goals today. I believe it has less to do with the html / native divide on mobile and more to do with the fact that it's getting ever more difficult to come up with genuinely innovative consumer facing solutions. However, I see massive value in "horizontal" apps. The two key features about smartphones is that they are geo-aware and inherently personal. I firmly believe we will see the rise of "city apps" where users can find highly personalized content within a geographic boundary. Public transport info, show times, new exhibitions, restaurant reviews, etc, etc. I don't know whether this will happen at the app or OS level, but the key point is that in the future it won't be so much about functionality per se, but how that functionality is organized." - David Semeria

Re: Video Of The Week: Gary Vaynerchuck - http://avc.com/2014...
"I really liked Gary's comments on how patience is so underrated in the industry. Similar to Fred's observations on companies like Return Path. FWIW, I believe the "throw it at the wall and see if it sticks" school of business has a lot to answer for. If you don't think it'll stick, don't throw it -- especially on someone else's dime." - David Semeria

"Yes but it would still be a human reading the x-ray image. The ability to transfer large amounts of information merely increases the mobility of labour (the mountain can now come to Muhammad). I see no fundamental difference between this situation and offshore call centres, for example. The real question is: to what extent can machines *replace* humans?" - David Semeria

"The real game-changer for TV will be the content, not the interface. By coincidence, this game-changer arrived recently in the form of Popcorn Time. Finally, the service that everyone has been waiting for... It's like Napster for video - so I'm told ;-)" - David Semeria

Re: What’s Ahead: The Information Age Transition - http://continuations.com/post...
"Albert, you write But the price of labor is under tremendous pressure from machines and from globalization. These are two very different issues. Globalization is not a new phenomenon. Already in the mid 1700s Adam Smith was laying down the fundamental arguments in favour of free trade between nations. What we are seeing today is simply the continuation of a longstanding trend where nations become more industrialized and begin to export their low labour costs. As David Byrne would say: same as it ever was. The current pressure from machines is, however, a new phenomenon. In recent presentations you have made the analogy between the industrial revolution and the current technological one we are seeing. You correctly point out that machines are now in a position to disrupt both non-industrial manual jobs (robots) and also professional ones (machine learning). I am less pessimistic than many when it comes to pressure from machines. I was reading the excellent feature on robotics in last..." - David Semeria

"Around the turn of the century I spent a few days in Yalta which is the Monte Carlo of Crimea. I was staying on the 16th floor of its best hotel (easy at $50/night) when I heard music through the window. It's funny how you can always tell the difference between live and recorded music, even when muffled. The music was live, but on the 16th floor? Investigation was required. I made my way up to the roof-top terrace and found a band of middle aged men playing immaculately. I and my girlfriend made up the entire audience. When, during a pause, I asked them why they were playing so well when no-one was listening they simply replied: we're paid to play, so we play. Later, having talked with many more people from the ex Soviet Union, I found this simple phrase sums up a great deal about Russian thinking. They pay us to play, so we play. They pay us to wage war, so we wage war. We're not rock stars, we're not ideologues. It's more about what will happen to us if we don't perform... Later..." - David Semeria
