What Freedom Means in Relation to Control

What freedom means to me is not the same freedom that is preached to the masses by broadcasting companies. It is neither freedom of choice nor freedom that relates to cost.

In its most fundamental state, any person is not tied to anyone else except perhaps the community which is family, extended family, and sometimes more than that. In that case, a person is familiar with/to all peers, which is also what enables trade without currencies. There is a level of trust.

As societies grow bigger and bigger (moving into mega-cities, as noted in the previous post) trust gets replaced by control. Rather than trusting one’s peers people increasingly dominate and reign over other people; it’s means of peer control and it regulates one’s behaviour.

In the software world too there is a move from small communities of privileged developers with access to expensive machines; these days, a lot of people have access to computers and moreover to the Internet, which connects many of these disparate people. Mechanisms of control rather than trust are over time being put in place and these range from simple censorship to all sorts of artificial restrictions.

Freedom is always hindered by control. It is a relation of opposites. Control is antithetical to freedom assuming that control is not one’s own. Whether in a society as broad of ours one can ensure total freedom is very much questionable, but one must always keep in mind that if freedom is the goal, then control by others is a threat; sometimes it is a necessary and legitimate threat, but often it is (mis)used as a pretext for someone else to take control over others.

Nanorobots: the new soldiers of medicine

Writing assignment by anonymous contributor

The nanorobot is an artificial tiny machine that can move on its own. The nanorobot consists of a central unit which can operate inside the human organisms, and of a group of additional units that back the central unit. Its task is to implement certain medical operations on separate organs and tissues. With a successful technology today, the future nanorobots will be able to perform many actions and solve many problems which modern medicine cannot solve. In addition, the nanorobots can cause various atoms and molecules to connect and create new material which can be use as a substitute for important substances in the human body, and the role of certain organs.

Challenging Task: One-point Tracking Without Localised Vicinity

THE previous post about validation with rotation put focus on large regions outside the heart, where there was greater separation between landmark points. In this case, initially I tested a general case where 120 points were put around a circular area in and outside the heart, showing more or less what got detected as the expected translation at each frame. I look at only one point at a time here, on purpose — meaning that for each point only its neighbours in the next frame are being compared and there is room for improvement if the whole spacial patch (e.g. 3×3 window) gets used in the current frame. This simplification was intentional here.

Heart rotation contour only

Informal QtOctave Demo

This Octave ramble is an experimental video where I try to present some elements of the program before preparing something more professionally put. In this part of a series I go just through some elements of QtOctave and show how it is used in practice. In the future I will prepare something much more polished that is planned in advance.
