Best Films – 2018

Raul Zambrano Film Leave a comment

While I managed to watch a film every 2.5 days on average, online sources were instrumental in making this a reality. The astounding public library system of the US county where I happen to live at the moment also played a significant role. In addition to facilitating access to academic books (usually on the expensive side) at no cost, it also provides free access to online film platforms.

This is the first time I make extensive use of this resource  – and certainly not the last. In fact, fifteen percent of the films I was able to catch this year delivered via this channel. In any event, I am still a big fan of the big screen and will not change that for any other platform.

It seems to me this year the quality of the films released was probably higher than in the recent past. Films like

Algorithms and Algocracy – II

Raul Zambrano Artificial Intelligence, Blockchain, Governance 1 Comment

In the previous post, I provided a simple definition of an algorithm to then explore their use in the digital world. While algorithms live from that there are fed as inputs, digital programs such as mobile apps and web platforms are comprised of a series of algorithms that working in sync deliver the desired output(s). Algorithms sit between a given input and the expected output. They take the former, do their magic and yield the latter.

There is a direct relationship between the complexity of the planned output(s) and the coding effort required for its delivery. The latter is usually measured by the number of coding lines in a given program. For example, Google is said to have over 2 billion coding lines (2×10^9) supporting its various services. You certainly need an army of programmers

Algorithms and Algocracy – I

Raul Zambrano Artificial Intelligence, Governance, Robotics 1 Comment

While the concept of an algorithm has been around for centuries, the same cannot be said about algocracy. The latter has recently gained notoriety thanks in part to the renaissance of Artificial Intelligence and Machine Learning (AI/ML) and is frequently used to describe the increased use of algorithms in decision-making and governance processes. Indeed, the so-called Singularity could be seen as an extreme and seemingly irreversible algocracy case where humans lose the capacity to control superintelligent machines and might even face extinction. Not sure that will ever happen though.

A more plausible scenario takes place when humans and human institutions rely on algorithms to make critical decisions without any reservations. This is happening today – the quasi-dictatorship of algorithms.

Smart contracts are not that smart

Raul Zambrano Blockchain, Governance, Innovation Leave a comment

Smart contracts are perhaps one of the most touted features of blockchain technology. While the idea itself dates from the end of last century,  blockchains provided the platform for actual implementation in the Internet era. Undoubtedly, Ethereum was the real disruptive innovator by enhancing the original but limited Bitcoin architecture with a plethora of programmable new features, smart contracts being one of them.1 In fact, Ethereum is defined as a Turing-complete platform.. This same development also opened the door for clearly distinguishing between blockchains and cryptocurrencies, the latter being just one application of the former, a general purpose technology of sorts.

Analysis of smart contracts can be undertaken from at least three different angles. These are 1. Finance; 2.

Waste no time waiting for e-Waste data

Raul Zambrano Blockchain, Climate Change, Human Development, Social Innovation Leave a comment

The town where I currently reside is planning to change its e-Waste collection policy starting next year. As it is today, town people can go downtown once a month and drop their old computers, laptops, monitors and the rest. This will now be reduced to one day per year. Missing that date will entail people having to go to some other place out of town to take care of business. Or one could try to go to a nearby and more affluent village where one can drop the stuff at any time. Probably not kosher, though.

I am not sure if this change is the result of budget cuts or lower demand for such service  – or both. I am not really following town decision-making processes. But I do know that e-Waste collection is a state law, and all towns must thus take care of business. Note that appliances such

ICOs: Endangered Species

Raul Zambrano Blockchain, Economics, Innovation Leave a comment

As expected, ICOs are finally cooling down. There are several reasons for this. First, ICO oversight by regulators in many countries has substantially increased. Regulators are poking not so much into new ICOs. Instead, they are doing deep dives into those that have already been completed and going after those who look fraudulent. Second, the token market is in a massive downswing. Some tokens have lost at least 90 percent of their value thus leading to substantial loses for ICO investors. As a result, crypto tokens have become much less attractive.

Third, many of the successfully completed ICOs are having a hard time showing or delivering on the ground results in spite of massive infusions of capital. While lack of maturity and technology constraints might play a role here, it may also

Uncertainty and Artificial Intelligence

Raul Zambrano Artificial Intelligence, Book review, Economics, Inequality, Innovation Leave a comment

In a world where perfect information supposedly rules across the board, uncertainty certainly poses a challenge to mainstream economists. While some of the tenets of such assumption have been already addressed – via the theory of information asymmetries and the development of the rational expectations school, for example, uncertainty still poses critical questions.

For starters, uncertainty should not be confused with risk. The latter in a nutshell can be quantified using probability theory. Based on existing data and previous behavior, we could say predict there is a 75 percent chance investments in the stock market can yield a 25 percent reward in say 5 years. This is not the case for uncertainty as here the outcome is entirely unknown. In other words, we have no idea what is going to

Nein Uber in Berlin

Raul Zambrano Uncategorized Leave a comment

Arriving in Berlin from Africa via Frankfurt proved to be a nightmare this time around. While the flight and connections were almost perfect, the same cannot be said about my luggage. I checked in one bag at the point of origin and asked the airline agent to confirm my bag will indeed show up in Berlin while ensuring the bag tag had the TXL symbol (for Berlin’s Tegel airport) and the right flight number printed on it. Both checks yielded positive results.

Twelve hours later I found myself waiting for my smallish suitcase at Tegel. Bags are unloaded in batches. I oversaw all three of them. The conveyor belt then stopped, telling me my bag did not board the plane in Frankfurt. Or maybe at the point of origin. No idea.

As far as I know, there are at least two lost and found windows in Tegel.

Visa on Arrival

Raul Zambrano Innovation, On-mission Leave a comment

My passport seems to profess a deep love for visa stamps. Every time the possibility of travel to another country arises, I can hear its excitement of filling yet another passport page with a brand new and (maybe) shiny visa stamp. The more, the merrier – although blank pages to host additional stamps are becoming scarce, yet again.

Finding an index for all sort of things is one of the traits of our data age. Yes, there is a passport-power index that ranks countries according to visa-free travel. For 2018, Japan and Singapore shared top honors followed by Germany and Denmark. The usual suspects sat comfortably in the basement: Pakistan, Somalia, Syria, Iraq, and Afghanistan. My passport is part of the middle-class having recently risen in the ranks thanks to the addition of the Schengen

Learning about Machine Learning

Raul Zambrano Artificial Intelligence, Innovation 2 Comments

A few months ago, as I was finishing a paper on blockchain technology, I received an unexpected comment on Artificial Intelligence (AI from here on in) from one of the peer reviewers. While addressing the overall topic of innovation in the 21st Century, I mentioned in passing the revival of both AI and Machine Learning (ML, not be confused with Marxism-Leninism) as a good example. The reviewer requested the deletion of one of the two terms as, in his book, they were exactly the same. Not so fast, was my prompt reply. In the end, both survived the peer review.

Looking at the history of AI helps shed some light on these concepts. While the AI term was coined in the 1950s, the work of Alan Turing, limited by the use of analog/mechanical computers, can be seen as its launching pad. Digital computers
