Notepad++ is a free (as in “free speech” and also as in “free beer”) source code editor and Notepad replacement that supports several languages. Running in the MS Windows environment, its use is governed by GPL License.

Based on the powerful editing component Scintilla, Notepad++ is written in C++ and uses pure Win32 API and STL which ensures a higher execution speed and smaller program size.

Brave is a free and open-source web browser developed by Brave Software, Inc. based on the Chromium web browser. The browser blocks ads and website trackers. The company has proposed adopting a Get paid to surf business model in a future version of the browser.

Brave created a new “blockchain-based advertising model that reforms the current system with privacy by design and 70 percent revenue share to users in the form of Basic Attention Tokens (BAT)”. Users may opt-in to view ads to earn BAT which they may convert into digital assets and fiat currencies, or use to support their favorite publishers, content creators, and companies.

According to Brave Software, “ad matching happens directly” on user devices which means that data is not sent to anyone.
