Data transfer - what it is?

Whilst you are online, everything is about transfer of data – thus, emails and web pages are basically a file that when you read or log onto, you are in essence downloading the file or transferring it to your screen so you can view it. If you watch a film or play a game online, these activities send data backward and forward in…

Structural Accommodation

A theme in my blogs is how the "structure" of data - rather than just the "content" - affects what that data can say and is capable of doing. In particular, I suggest that certain structures tend to reinforce certain contents; this means that a structural imposition can have an effect similar to a contextual imposition. Structure is an interesting conversation…

What is Data Science? 24 Fundamental Articles Answering This Question

Many people new to data science might believe that this field is just about R, Python, Hadoop, SQL, and traditional machine learning techniques or statistical modeling. Below you will find fundamental articles that show how modern, broad and deep the field is. Some data scientists are actually doing none of the above. In my case, I don't even code, but instead, I make various applications talk to each other, in a machine-to-machine communication framework. It is true though that most data…

#Blockchain derivatives will replace structured products #fintech

The era of structured products is coming to an end. These are financial instruments that have different payouts, like derivatives, based on different outcomes. They are different from derivatives in that they are built like bonds. One of the biggest short coming of these is their lack of a large secondary trading market before maturity. That is, if you try to sell one before its maturity date, you might get what the financial industry calls a “haircut”. In finance this is commonly referred…

How do you search for a #sensor in Antartica on your Internet Of Things (#IoT) browser? Aka: Does #Arduino dream of electric sheep?

If you have ever launched a web page on a Raspberry Pi or Arduino, you know that it feels a bit like magic. How is it possible that a device the size of a credit card can be a web server? Its awe inspiring to be sure. For me, it leads to one of the key questions I have about the Internet of Things and how it will affect our world. How are we going to organize and search for all of these billions of devices?

When the web began, there were millions of…

Building an Algorithm to Break Strong Encryption

Here I discuss breaking encryption keys that rely on the product of two very large prime numbers. In other words, the interest here is to factor a number (representing a key in some encryption system) that is the product of two very large primes. Once the number is factored, the key is compromised. Factoring such large numbers is believed to be computationally non-feasible, thus the interest in discovering new algorithms to disprove this conjecture, and specifically to factor large numbers…
