1. Why I write posts on Dev.to, and you should too
I have written nearly thirty posts on Dev.to and supplied countless (constructive) comments on posts of others. On the whole, I have found the experience rewarding and the community appreciative and supportive, even when they disagree with me. Here are the three main reasons why I will continue to write and I suggest you try it yourself, if you have not yet done so. If you already write posts, perhaps you might want say why you do in the comments below.

2. MicroPython officially becomes part of the Arduino ecosystem
Last month MicroPython officially became part of the Arduino ecosystem. The inclusion of MicroPython as a member of the Arduino family is an exciting development for those interested in using Python to develop for any board with a serial REPL interface, like the ESP32. The ESP32 is a low-cost, low-power system-on-chip (SoC) microcontroller with built-in WiFi and Bluetooth capabilities, making it a popular choice for a wide range of projects, including IoT devices, home automation, and wearable e…

1. Removing Google Analytics and Replacing it with a cookie free Javascript Geo Tracking app
Running Google Analytics slows down site performance because adding any script to our html head tag adds overhead to our app. This includes any third party libraries also added to the head tag.
I found a free jsonp geo tracking app, pulled country, city and ip variables into my javascript, then passed these vars into a Lambda function and saved them as a json file to a simple AWS S3 bucket. This way I could avoid adding the google analytics to my head tag, thereby speeding up my performance a b…

2. Redirects and rewrites with Edge computing
💬 Intent
Edge Computing is an architectural pattern that lets you bring computational resources (processing, data, etc.) closer to where it's needed in order to improve response times and save bandwidth used on requests.
Within AWS, CloudFront is the Content Delivery Network (CDN) service used to speed up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users.
😖 Problem
Imagine a scenario where you have a new website under a new domain,…

3. PyBricks ile ileri geri ve sağa sola dönme
Lego'nun Technic Large Hub'ı için varsayılan firmware yerine PyBricks firmware'ü kullanarak Lego cihazınızda MicroPython kullanabiliyoruz.
Bu yazımızda Lego'nun uzaktan kumandası ile, _2 motor_lu bir düzeneğin çalıştırılması anlatılmıştır.
PyBricks firmware yükleme
Bunun için öncelikle Firmware'ü sisteme yüklemek gerekiyor ki, bunun için Lego Technic Hub üzerindeki bluetooth tuşuna basılı tutarken cihaza USB kablosunu takarak, ışıkların birkaç kere yanıp sönmesini bekledikten sonra sisteme g…
