Manage Neovim plugins (and more!) with Nix and Home Manager

Highly extensible software like Emacs, Vim, and Neovim tend to grow their own package managers. A software developer, for example, might want to install editor plugins that hook into a particular programming language's linter or language server. The programmer's text editor is therefore extended to support managing additional software to extend the text editor. If this loop continues for too long, the programmer's editor becomes more delicate and complex. The remedy for this problem is to manage software using dedicated tools apart

Dynamic PGO in .NET 6.0

Dynamic PGO (Profile-guided optimization) is a JIT-compiler optimization technique that allows JIT to collect additional information about surroundings (aka profile) in tier0 codegen in order to rely on it later during promotion from tier0 to tier1 for hot methods to make them even more efficient.

What exactly PGO can optimize for us?

1. Profile-driving inlining - inliner relies on PGO data and can be very aggressive for hot paths and care less about cold ones, see dotnet/runtime#52708 and dotnet/runtime#55478. A good example where it has visible effects is this StringBuilder benchmark:

2. Guarded devirtualization - most monomorphic virtual/interface calls can be devirtualized using PGO data, e.g.:

void DisposeMe(IDisposable d)

These are some notes about settings I like to use when I code in Visual Studio. They are completely optional.

• Automatic brace completion = false
• Dark Theme Tools -> Options -> Environment -> General
• Disable Semicolon Bullshit Tools -> Options -> Text Editor -> C# -> IntelliSense
  • Automatically complete statement on semicolon = false

Generic tensor library in C# in a week

Hello!

For this article we take Tensor as a N-dimensional array whose last two axes might be interpreted as Matrix and/or the last axis might be interpreted as Vector. For TLDR the result is here.

What do we want?

1. Tensors (N-dimensional storage)
2. Implementation of methods and functions for working with tensors as with data storages

Tips on exposing F# to C#

Api and Methods

I suggest that you create one or more Api.fs files to expose F# code in a C# friendly way.

In this file:

• Define functions with PascalCase names. They will appear to C# as static methods.
• Functions should use tuple-style declarations (like C#) rather than F#-style params with spaces.
