Running stats objects for pytorch: mean, variance, covariance, second-moment, quantiles, topk, and combinations.
'''
To use a runningstats object,
1. Create the the desired stat object, e.g., `m = Mean()`
2. Feed it batches via the add method, e.g., `m.add(batch)`
3. Repeat step 2 any number of times.
4. Read out the statistic of interest, e.g., `m.mean()`
Built-in runningstats objects include:

Nix language changes

This document contains some ideas for additions to the Nix language.

Motivation

The Nix package manager, Nixpkgs and NixOS currently have several problems:

  • Poor discoverability of package options. Package functions have function arguments like enableFoo, but there is no way for the Nix UI to discover them, let alone to provide programmatic ways to

Linux on MacBook Pro Late 2016 and Mid 2017 (with Touchbar)

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

How to set up distributed builds with nix
