Fighting Spam on YouTube with TensorFlow & Python Simply Explained 2021-06-25 | I'm sick of crypto-related spam comments on YouTube, so I trained a machine learning model to delete them! A script runs periodically and uses the text classifier to filter the latest comments on my videos.The filter is surprisingly effective, even though the training dataset is relatively small. I'll keep expanding the dataset and retrain the classifier so it becomes more accurate overtime.💌 Sign up for Simply Explained Newsletter:newsletter.simplyexplained.comMonthly newsletter with cool stuff I found on the internet (related to science, technology, biology, and other nerdy things)!

What is FreeRTOS? (ESP32 + Arduino series) Simply Explained 2021-03-11 | Want to multitask on your ESP32? By using FreeRTOS you won't have to worry about scheduling your tasks and making sure that all of them are given enough processing time.FreeRTOS is a real-time operating system, designed to run on microcontrollers. It has a scheduler that gives each task a fair share of CPU processing power. When that's not possible, the scheduler will use a task's priority to give the most important ones the most CPU time.⚡️Other videos in this series:youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU(Everything you need to know about programming the ESP32 by using the Arduino Framework)🌍 SocialTwitter: twitter.com/SavjeeFacebook: facebook.com/SavjeeBlog: savjee.be❤️ Become a Simply Explained member: youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join

DNA Data Storage is the Future! Simply Explained 2019-06-17 | Floppy drives, hard drives and SSD's could soon be replaced by DNA storage. But why is it so much better? And what are the challenges before we can use DNA as storage media? Let's take a look!Current storage techniques have 3 problems: they are not robust, have a low density and each media requires a special reader. DNA could solve all of these problems. It's very robust (it can easily last a few centuries), it's very high density (storing many petabytes of data per gram) and we already have readers for it. 🎬Take a look behind the scenesyoutu.be/MTr2dfKtRFU📚SourcesThis video is based on the work/research of others.
