Tell HN: Political Detox Week – No politics on HN for one week

Like everyone else, HN has been on a political binge lately. As an experiment, we’re going to try something new and have a cleanse. Starting today, it’s Political Detox Week on HN.For one week, political stories are off-topic. Please flag them. Please also flag political threads on non-political stories. For our part, we’ll kill such stories and threads when we see them. Then we’ll watch together to see what happens.Why? Political conflicts cause harm here. The values of Hacker News are intellectual curiosity and thoughtful conversation. Those things are lost when political emotions seize control. Our values are fragile—they’re like plants that get forgotten, then trampled and scorched in combat. HN is a garden, politics is war by other means, and war and gardening don’t mix.Worse, these harsher patterns can spread through the rest of the culture, threatening the community as a whole. A detox week seems like a good

Mux – A lightweight, fast HTTP request router for Go

mux is a lightweight fast HTTP request router (also called multiplexer or just mux for short) for Go 1.7.

The difference between the default mux of Go’s net/http package and this mux is,
it’s supports variables and regex in the routing pattern and matches against the request method. It also scales better.


Vars URL Matcher
GetVars in handler
GetQueries in handler
URL Matcher
Header Matcher
Scheme Matcher
Custom Matcher
Route Validators
Http method declaration
Support for standard lib http.Handler and http.HandlerFunc
Custom NotFound handler
Respect the Go standard http.Handler interface
Routes are sorted
Context support
Feature request are welcome

Example (Method GET):

package main

import (


func main() {
r := mux.Classic()

//URL: https://localhost:8080/home
r.HandleFunc(http.MethodGet, “/home”, homeHandler)

//URL: https://localhost:8080/home-1
r.Handle(http.MethodGet, “/home-1”, http.HandlerFunc(homeHandler))

//URL: https://localhost:8080/home-2
r.Get(“/home-2”, homeHandler)

//URL: https://localhost:8080/home-3
r.RegisterRoute(http.MethodGet, r.NewRoute().Path(“/home-3”).HandlerFunc(homeHandler))

//URL: https://localhost:8080/home-4
r.RegisterRoute(http.MethodGet, r.NewRoute().Path(“/home-4”).Handler(http.HandlerFunc(homeHandler)))

errorHandler := func(errs []error) {
for _ , err := range errs {
if != len(errs) {

Google’s DeepMind is Opening Up Its Flagship Platform To AI Researchers Outside the Company

Artificial intelligence (AI) researchers around the world will soon be able to use DeepMind’s “flagship” platform to develop innovative computer systems that can learn and think for themselves. From a report on BusinessInsider: DeepMind, which was acquired by Google for $400 million in 2014, announced on Monday that it is open-sourcing its “Lab” from this week onwards so that others can try and make advances in the notoriously complex field of AI. The company says that the DeepMind Lab, which it has been using internally for some time, is a 3D game-like platform tailored for agent-based AI research. […] The DeepMind Lab aims to combine several different AI research areas into one environment. Researchers will be able to test their AI agent’s abilities on navigation, memory, and 3D vision, while determining how good they are at planning and strategy.

Open-sourcing DeepMind Lab

Artificial general intelligence research in DeepMind Lab emphasizes navigation, memory, 3D vision from a first person viewpoint, motor control, planning, strategy, time, and fully autonomous agents that must learn for themselves what tasks to perform by exploring their environment. All these factors make learning difficult. Each are considered frontier research questions in their own right. Putting them all together in one platform, as we have, represents a significant new challenge for the field.

Dockuwiki: A containerized wiki that backs itself up via git

A good old fashioned self backup-ing dokuwiki in a box.

But what is it?

A self installing instance of the venerable dokuwiki that backs itself up to a git repo every hour. All wrapped up in a docker image (sorry, bow not included). Blog post with details here.

But why is it?

I wanted a dead simple method of setting up wikis without hassle. Using a git repo for backups simplifies deployment and eliminates the need for a host with persistent storage.

I don’t get the name

I tried to be cute by combining “Docker” and “Doku”. Get it? Hah!

How do I use it?

Create a git repo somewhere that the docker host can access. Just don’t commit anything to it! In step 2, let’s pretend you used BitBucket for hosting the repo.
$ docker run -d –restart=always –name=wiki -e -e -p 3000:3000 ericbarch/dockuwiki
On the first run, the container will generate a
