NeuroOn validation poster

Also in: [pl]

Winding up the long-overdue NeuroOn's signal research together with Ryszard Cetnarski from Nencki Institute of Experimental Biology in Warsaw (github profile) we created a scientific poster summarizing our findings. We presented it at the 6th International Conference "Aspects of Neuroscience" (link) taking place between 25-27th of November in Warsaw, Poland.

Just as the research notebook itself is freely available on Github and licensed under MIT License, our poster is released as completely open, under a little bit more restrictive CC-BY-SA license.

Since our research wasn't criticized beyond data representation methods on the course of several months, it should be safe to assume that it's ready to present to a wider audience. On the course of the following week you may expect a full NeuroOn verification summary blogpost with results explained in simple terms, leaving no ambiguities regarding the device.

Hackers, researchers, biohackers

Note: I am still working on NeuroOn signal analysis. You can expect to see the hypnogram1 comparisons first together with time-synchronized signal files and all the code in an open Jupyter Notebook2

Hackerspaces and biology

As a long time Citizen Science and Open Source supporter I love the idea of Hackerspaces3 - collaboration workspaces allowing individuals to work on their own technical projects, sharing tools and knowledge. I consider them a vital counterpart to Academic research labs, where people are not bound by strict rules and grants. Hackerspaces excel in very disorganized research and development of various IT and electronic projects, producing a lot of open designs and proof of concepts4.

Many researchers point out that it is possible only due to the nature of IT and electronics allowing rapid prototyping and near-instantaneous results - something which couldn ...

The analysis and all the data files are available for peer review at my Github.

NeuroOn Today

I was intending to start a blog for a long time, kept back by the feeling that I didn't really have anything valuable to share. This changed when I found a Polish startup - NeuroOn1 over two years ago. My first post2 expressed all the hopes I had for the sleep mask and skepticism at the clear disregard for scientific standards of its creators. Since it consists mostly of quotes I don't want to risk misinterpretation of IntelClinic employees by translating it fully. I ended it with the following paragraph:

The NeuroOn sleep mask cannot work exactly as advertised - it cannot utilize a proper EEG signal. While it can detect a REM phase in sleep very roughly, it ...

Second steps in React

For some time I've been using React JS stack in my professional projects at X-Team and I decided to share some knowledge. React is just one piece piece of puzzle, requiring Redux, React-Router, Webpack and Babel to create truly interesting architecture. I've met many people having problems with grasping that, struggling to go beyond simple component state of their application. Since I had similar problems learning this modular approach, I decided to give a short presentation on the topic.

Initially given on April 27th in a wonderful Noisebridge hackerspace, I updated it a little after React Europe 2016 and presented again at MeetJS Warsaw on the 7th of June 2016.

The presented application of React + Redux is just a simple view authentication method, which nicely highlights the simplicity of the architecture. All links - including "by then you should know" are clickable, so feel free to browse sources recommended by me. All code itself is either runnable or has a pseudocode warning on the slide.

SurviveJS - a guide to modern web development with React and Webpack

This time I wish to share a recommendation. For two years I've been developing in JavaScript in Angular, using various in-house habits and techniques of my respective employers. I have tried vanilla JS and CoffeeScript, Grunt and Gulp, Jasmine and Mocha, various deployment models. I have been learning various tools on my own, but I always seemed to lack the understanding of what is their specific place and strength in a project.

I never really got what's so good in React and Webpack, even though I've completed the tutorials before. I got myself to understand ES6 and BabelJS, but never intuitively realized the potential of const and modules, even though my taxBrackets project uses a lot of their functions.

There are lots of great tutorials and showcases of various tools, showing how each of them can simplify and speed up the development. Still - nothing can replace seeing an experienced professional make most of his toolbox and guide you through their work process.

Recently I've seen such a guide, creating a simple ...
