+# Blender 
+
+Blender is an "[open-source](open_source.md)" 3D modeling and [rendering](rendering.md) [software](software.md) -- one of the most powerful and "feature-rich" ones, even compared to [proprietary](proprietary.md) competition -- used not only by the [FOSS](foss.md) community, but also the industry (commercial [games](game.md), movies etc.), which is an impressive achievement in itself, however Blender is also a [capitalist](capitalist.md) software suffering from many not-so-nice features such as [bloat](bloat.md).
+
+After version 2.76 Blender started requiring [OpenGL](opengl.md) 2.1 due to its "[modern](modern.md)" EEVEE renderer, deprecating old machines and giving a huge fuck you to all users with incompatible hardware (for example the users of [RYF](ryf.md) software). This new version also stopped working with the [free](free_software.md) [Nouveau](nouvea.md) driver, forcing the users to use NVidia's proprietary drivers. Blender of course doesn't at all care about this.

 - **advanced notation**: ability to understand the notation that's often used in papers etc. (the big sigma for sum etc.)
 - **formal [logic](logic.md)**: computers are based on Boolean logic, knowing basic formulas and theorems here is crucial (e.g. the completeness of [NAND](nand.md)), formal logic is also just generally used in formal texts, one should know about predicate vs propositional logic, the notation symbols, etc.
 - **[linear algebra](linear_algebra.md)**: aka "vectors and matrices", essential in many fields such as [graphics](graphics.md) and [machine learning](machine_learning.md).
