Citizenship in a Republic By Theodore Roosevelt (1910)

Posted on November 15, 2020

Here there are some quotes from the Citizenship in a Republic By Theodore Roosevelt that I found were worth keeping and reflecting upon. Each of the following paragraphs represents a segment. It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweatRead More

Is "what doesn't kill you makes you stronger" wrong?

Posted on November 3, 2020

What doesn’t kill you kills the weak and gives you the perception that you became stronger.

Conspicuous consumption

Posted on November 1, 2020

The fusion of both words, conspicuous consumption, is a term coined by Thorstein Veblen in 1899 but it is easily applicable to modern society. It is an economic theory that does not shine optimism. Based on the meaning of the words separately Conspicuous: Attracting notice or attention. Consumption: The action of using up a resource. Put together, conspicuous consumption refers to buying expensive goods to display wealth rather than covering the real consumer needs. This economic theory criticizes the industrializedRead More

The new software: Advantages and disadvantages

Posted on September 29, 2020

Recently I published a post about the new software paradigm. The new paradigm of software is the one that the coder does not directly program each of the cases for any of the given inputs. The new paradigm uses training data to let the computer learn the outputs for each input. The computer programs itself while the coder and the software developer’s job is to prepare the data and set the target. The new paradigm seems to bring new challengesRead More

The new software: Less coding more data

Posted on September 1, 2020

Software like everything is evolving but it is evolving differently than I thought. When I was studying computer science at the university I thought that the future was parallelism. We were taught only one class in parallel programming. Multi-core computers were on the rise and it seemed to be the thing to learn. Since then my opinion has changed. There is indeed the need for parallel programmers but it is not as big as I had foreseen. Most of theRead More

Want to reduce the plastic usage? Try the wellness approach

Posted on August 25, 2020

We’ve been facing the problem of plastic usage wrong. Plastics cannot be recycled [1] and when they can be recycled it is not an easy straight forward process. Yet, everyone is using them out of convenience. They are cheap and nobody cares about the environment when it comes into conflict with their pocket. The solution? Studies should be found to find if plastics are nocive to human health. If people worry that they or their kids will get cancer, theyRead More

Go to the bottom of your SMS and text people regularly something like: Hi Joe, It’s Roc here, we haven’t spoken in ages!! I hope you’re fine. What’s the latest with you? No rush on the reply Don’t skip people The same for emails. But search for random letters and see what the autocomplete in the “to” field shows. Look at Linkedin (and other social media) and prise people through a private channel for something they did recently. No likesRead More

Convert a mask into a Polygon for images using shapely and rasterio

Posted on August 7, 2020

Sometimes it is necessary to transform masks into polygons to use polygon operations. The way to transform a raster or a binary mask into a polygon is pretty easy. Most of the solutions I found online were the other way (from polygon to a mask). But for my project I needed to convert the mask to a polygon.

Time at Risk

Posted on June 27, 2020

Time at Risk == Value at Risk (if we replace value by time) E.g. An insurance company’s 90% TaR is 3 year for liquidity risk – That means that for 3 years the insurer under the current financial structure would be 90% safe Time at Risk (TaR for short): is the maximum period of time that an adverse event would not occur. We calculate it as follows: The units are cases/person-year
