Another Online Courses

Well, well, well…
It has been some time since I wrote the last blog post. And I won’t make the same mistake promising that I will write more. Not like there is nothing happening in my life. I recently finished two online courses and I am going to give you a review of them. Rather there is happening so many things that I just have to put my focus into different things. Or I am just being lazy – pick your excuse.

Here is a quick review of Cryptography and AI online courses

Handwriting OCR Poster – Intel ISEF 2018

Poster Handwriting OCR - Intel ISEF 2018

From zero to Intel ISEF 2018

"The Intel International Science and Engineering Fair (Intel ISEF) is the world’s largest international pre-college science competition."

“The Intel International Science and Engineering Fair (Intel ISEF) is the world’s largest international pre-college science competition.”

I am not sure if it is the largest pre-college competition, but with the hundreds of students from around the world, the atmosphere of the whole event is simply amazing. At Intel ISEF students get a chance to present their science projects and meet each other. For many people, including me, attending ISEF is a pretty big deal. The prizes are high, the competition has a good recognition, and you just hope that all the hard work finally pays off.

MOOCs — Massive Open Online Courses

The MOOCs (massive open online courses) are becoming a common thing, yet there are some doubts about them. To date, I’ve fully—with all assignments and exams—completed three courses. Yes, I finished another great course called Introduction to Computational Thinking and Data Science from MIT (on edX). But how to choose suitable courses? And is it worth taking them? And should we purchase the certificates from them?

Quick Fix: No DISPLAY Variable while using Matplotlib on Android

A few weeks after releasing my tutorial for installing Jupyter Notebook on Android, I ran into this issue of Matplotlib: TclError: no display name and $DISPLAY environment variable, whenever I tried to use it in Jupyter Notebook on Android. This problem got me puzzled for a while because I knew it used to work when I was writing the tutorial. Luckily, there is a one-line fix for this issue. So, in case you don’t have time for any other details, just put this line at the beginning of the notebook:

%matplotlib inline
Matplotlib no display ERROR on Android

Check the example, it works!

Make Your Habits Come True

Don’t worry, this blog post will not include any stupidly long and heartbreaking story how I become motivated. Instead, I would like to give you some tips from my personal experience how I stick to my new habits. You may not trust me, but keep in mind that I already successfully completed a few on-line courses and I still take new ones ? (just try to google the completion rate of MOOCs).

End of GCI

It is kind of sad bud the GCI ended (on  25. January). And I thought that I will have some free time. But in the end, I am writing this 4 days after the deadline of GCI. Since I already wrote articles about OpenMRS and about my experience with GCI. And I don’t like to repeat myself, I wouldn’t go over it again. However, I would like to kind of extend these articles.

OpenMRS

Some of you may know that I am participating in Google Code-in and that I am completing some tasks for OpenMRS. So, I guess that now is the right time to explain what OpenMRS really is.
