Using the nipkgs unstable channel

Motivation

There a times when you need to build something from the nix unstable channel. For example the master contains a new package you need, but the next nixpkgs release is somewhere in the future, and you need this package now. In this guide I want to show how to install packages from unstable by using nix-env. Furthermore I hope to give a basic understanding of the channels concept.

What are nix channels?

A channel is a set of expressions which includes severall build, installation and configuration instructions for packages, services and the system itself. The repository normaly used here is nixpkgs. It is developed at https://github.com/NixOS/nixpkgs.

What is the nix unstable channel?

The unstable channel is a copy of the NixOS/nixpkgs master. It is pulled from github once in a while and will be available from a mirror under https://nixos.org/channels/nixpkgs-unstable. Since NixOS uses half-anual released stable channels, some changes (especially new f

Getting started with Linux kernel development

Prerequisites

The Linux kernel is written in C, so you should have at least a basic understanding of C before diving into kernel work. You don't need expert level C knowledge, since you can always pick some things up underway, but it certainly helps to know the language and to have written some userspace C programs already.

It will also help to be a Linux user. If you have never used Linux before, it's probably a good idea to download a distro and get comfortable with it before you start doing kernel work.

Lastly, knowing git is not actually required, but can really help you (since you can dig through changelogs and search for information you'll need). At a minimum you should probably be able to clone the git repository to a local directory.

High level description Bitcoin Core's fee estimation algorithm

The algorithm takes as input a target which represents a number of blocks within which you would like your transaction to be included in the blockchain. It returns a fee rate that you should use on your transaction in order to achieve this.

The algorithm is conceptually very simple and does not attempt to have any predictive power over future conditions. It only looks at some recent history of transactions and returns the lowest fee rate such that in that recent history a very high fraction of transactions with that fee rate were confirmed in the block chain in less than the target number of blocks.

Transactions can occur with a nearly continuous range of fee rates and so in order to avoid tracking every historical transaction independently, they are grouped into fee rate "buckets". A fee rate bucket represents a range of fee rates within which the algorithm treats all transactions as having approximately the same fee rate and the answer th

In your local clone of your forked repository, you can add the original GitHub repository as a "remote". ("Remotes" are like nicknames for the URLs of repositories - origin is one, for example.) Then you can fetch all the branches from that upstream repository, and rebase your work to continue working on the upstream version. In terms of commands that might look like:

Add the remote, call it "upstream":

git remote add upstream https://github.com/whoever/whatever.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream
