Best VPN Services in 2021

A VPN - or Virtual Private Network - is a piece of software that you can download to your computer, phone and other devices to help you stay more private online. By encrypting all the data that you send and receive on the internet, VPN services are the ideal tool to ensure that no prying eyes can track what you’re doing on the web.

It adds an extra layer of security to whichever network you are trying to connect to, be it your home broadband, public Wi-Fi, or your mobile connection. It allows you to send and receive data privately while connecting to that network.

VSCodium - Open Source Version of VS Code

Listen article as podcast episode

Every time you launch VS Code, Microsoft collects telemetry unless you’ve manually disabled it. Even then, you’re trusting a proprietary binary that differs from the open-source code it’s built from. VSCodium eliminates this uncertainty. Built from the same MIT-licensed source without Microsoft’s tracking infrastructure, it’s VS Code as the source code intended, not as Microsoft packaged it. The trade-off is losing access to a handful of proprietary extensions. For many developers, that’s worth it.

Python on Google Colab

Google Colab is a powerful platform for writing and executing Python in your browser with zero configuration required, free access to GPU, and easy sharing, learning and quickly developing machine learning models in Python. It is based on the Jupyter notebook and supports collaborator development.

Google Collab allows developers to write and execute arbitrary Python code through the browser, document the code that supports mathematical equations, create, upload and share notebook from and to Google Drive, import and publish notebooks from GitHub, import external datasets from Kaggle. It also allows to integrate and support ML libraries such as PyTorch, TensorFlow, Keras, OpenCV, and finally, free cloud service with free GPU (graphical processing unit) and TPU (tensor processing unit) acceleration.

Protecting Server with Fail2Ban: The Ultimate Guide

As soon as you start your server, it immediately jumps into the ocean of botnets trying to login with common credentials. And if your server has anything useful, sooner or later it may become a target for script kiddies or even more advanced folks with powerful computers and latest technologies, including Artificial Intelligence.

You can save your server from the botnets and somewhat complicate life for hackers using Fail2ban.

Fail2Ban is an IPF - Intrusion Prevention Framework that protects servers from external attacks. It was created by Cyril Jaquier (Switzerland) back in 2004 and since then it is under active development by the growing community.
