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. 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be 💌 Newsletter: https://newsletter.savjee.be (Once a month) ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join 👩‍💻 Source code: Available on GitHub: https://github.com/Savjee/yt-spam-classifier ❓❓ Frequently asked question: ❓ Why do I still see spam comments on your channel? First, not all comments are caught by the AI and still require manual intervention. Secondly, the script runs on a fixed interval. Give it some time to run.

Once you have FreeRTOS tasks running, you might want to manage them. The scheduler can stop, suspend, and resume individual tasks. You can control tasks from within or you can use task handles to control them from anywhere in your code. ⚡️Other videos in this series: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join 💌 Newsletter: http://newsletter.savjee.be (no more than once a month)

Does your ESP32 need a constant WiFi connection? Use a FreeRTOS task to constantly check your connection, and re-establish it when needed. This code has been super robust for me. I've been using it for my Home Energy Monitor, and it has been running reliably for years. ⚡️Other videos in this series: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join 💌 Newsletter: http://newsletter.savjee.be (no more than once a month)

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: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join

Run multiple tasks on the ESP32 with FreeRTOS. For instance: blinking two LED's at different intervals or increment two counters at the same time. A FreeRTOS task is nothing more than a standard C (or C++) function. Nothing fancy, very easy! Most ESP32's have a dual-core processor, so FreeRTOS will balance your tasks across cores. This technique also works for single-core versions of the ESP32. In that case, FreeRTOS will rapidly switch between tasks, giving the impression that it's multitasking. ⚡️Other videos in this series: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join 💌 Newsletter: http://newsletter.savjee.be (no more than once a month)

mRNA vaccines have to potential to end the COVID19 pandemic. How do they work? Are they safe? And how could they've been developed so quickly? The main idea of mRNA vaccines is to trick our bodies to produce part of a virus. This kickstarts our immune response, without getting us sick. All that's needed is a part of the virus's DNA or RNA, packaged into mRNA. Cool! 📚 Sources used to make this video: https://savjee.be/videos/simply-explained/mrna-vaccines/ Clarifications: - Initial test reports indicate that the vaccine is safe in the short-term (with few people having very mild complaints). However, we don't know what effects it might have in the long run.

NoSQL databases power some of the biggest sites. They're fast and super scalable but how do they work? Behind-the-scenes, they use a keyspace to distribute your data across multiple servers or partitions. This allows them to scale horizontally across many thousand servers. NoSQL databases can operate in multiple modes: as key-value store, document store or wide column store. You can run your own NoSQL database with software like Cassandra, CouchDB, MongoDB or Scylla. You can also use a cloud version like AWS DynamoDB, Google Cloud BigTable or Azure CosmosDB. 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be ❤️ Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join

The ESP32 can consume a lot of power when you keep it running at full speed. Here, I'll go over all the different modes that allow you to reduce power consumption and save your battery. The best way is by using one of the sleep modes, such as Deep Sleep mode. In this mode, the entire CPU is powered down and only a clock is running so the board can wakeup after a certain period of time. ⚡️Other videos in this series: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) 🌍 Social Twitter: https://twitter.com/Savjee Facebook: https://facebook.com/Savjee Blog: https://savjee.be Become a Simply Explained member: https://www.youtube.com/channel/UCnxrdFPXJMeHru_b4Q_vTPQ/join

When efficiency increases, consumption drops, right? Errr... No.. So far, increased efficiency has mostly lead to increased consumption.

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 scenes https://youtu.be/MTr2dfKtRFU 📚Sources This video is based on the work/research of others.

The state pattern is used to keep track of the state of a process. In this video I'll use an order on Amazon.com as an example. Each order moves to a specific process and the user has limited options at each state. For instance: you cannot cancel an order once it has been shipped. But you can cancel it at previous states. TIP: Set the properties in your classes to "private". I've forgot to do that here, but it's important to encapsulate them and only allow modification through a getter/setter. Interested?

The adapter pattern allows you to make different classes with different interfaces work together, without changing their source code. You can compare it to adapters in real life. Say you're traveling from the United States to Europe. If you want to charge your devices, you'll need an adapter to convert the European wall outlet to the US one. In this case the adapter should "implement" the European plug and expose a US plug for you to use. Interested?

The facade pattern is used to hide a lot of complexity behind a single method. I'll use a home theater system as an example because those can be quite complex to control and set up for a particular use case. Interested?

Often when information in one part of application changes, other parts need to be updates. This is the problem that the Observer pattern solves very efficiently. In this example we'll program a weather station that notifies a fan and a temperature display every time a new measurement was taken. Interested?

With the Decorator pattern you can add behaviour to classes dynamically. In this example I'll show you how to program a system to sell Tesla cars with many options (such as Auto Pilot). Each option affects the price of the car differently and a customer can choose many options or none at all. This is exactly the kind of problem that you can solve efficiently with a Decorator pattern. Interested?

In this video I will show you how you can get a free SSL certificate for your CloudFront distribution with the AWS Certificate Manager. ► What is SSL/TLS? SSL/TLS is a security technology that encrypts all traffic between your browser and a webserver. It also ensures that you're talking to the correct server and not with a man-in-the-middle. ► Advantage of AWS Certificate Manager? It's free of charge, easy to use with other AWS services and it automatically renews your certificates when they expire. You can set it up once and than forget it! ► Limitations As of right now you can only use the generated certificates with Elastic Load Balancers and CloudFront distributions. Amazon will probably extend the support to many more services in the future. ► Want to know more?

In this video I will show you how you can host a static website on Amazon S3. Want to automate this process? You can use s3_website to automatically setup your bucket and deploy your website. Check out my tutorial on how to use s3_website: https://www.youtube.com/watch?v=sshXVtr29HU ► What is S3? S3 stands for Simple Storage Service, an online storage service that allows you to store unlimited files in the cloud. ► Why would I use S3 instead of a regular host? Regular shared hosting providers charge you a fixed amount every month. That's regardless of the amount of files you store or the amount of visitors you get. Most cheaper webhosting companies also don't cope well with high traffic websites. Suddenly got featured on Reddit or Hacker News? A regular hosting provider might suspend your account for all the traffic! With S3 you only pay for what you use and it's highly scalable. ► What does it cost? To give you an example of cost: when my blog receiver 1000 visitors per month I was paying just 6 cents to host it! Check out more detailed S3 pricing here: https://aws.amazon.com/s3/pricing/ Or use the calculator to estimate your AWS bill: http://calculator.s3.amazonaws.com/index.html ► I want to read more!
