The Libreboot C201 from Minifree is really really really ridiculously open source

 Open source laptops – ones not running any commercial software whatsoever – have been the holy grail for free software fans for years. Now, with the introduction of libreboot, a truly open source boot firmware, the dream is close to fruition. The $730 laptop is a bog standard piece of hardware but it contains only open source software. The OS, Debian, is completely open source and… Read More

Show HN: Legal Concepts for Founders – Online Handbook

Here at Clerky, we build software to make legal paperwork easier for startups and their attorneys. We are the most popular way for startups to get formation paperwork done, and have products covering everything else typical seed-stage startups need.
Chris and I started Clerky in 2011. As startup attorneys, we noticed that many startups had costly errors with their legal paperwork – usually the result of using low-quality services or DIY approaches. With our engineering backgrounds, we knew that this problem could be solved through software built with the right legal expertise. Thus, Clerky was born.
As startup attorneys, we did a lot of legal paperwork for founders. But because we did the work ourselves, and because every email came with a steep price tag attached to it, we weren’t exposed to the full range of questions we get at Clerky. As a result of having largely unfiltered feedback from founders, and

Conexant and Amazon bring Alexa to Raspberry Pi with ‘AudioSmart 2-mic Development Kit’

Amazon’s Echo devices are incredible. I’ll admit that I was a skeptic at first, but once I got my own, I was hooked. Not only can the Alexa voice assistant provide me with important data like weather, news, and traffic, but it can play music too. Most importantly, it serves as a brilliant IoT control unit. My house has several WiFi connected power outlets, and I can verbally tell Alexa to turn off my lamps. It can even control my television! Much of Amazon’s success with Echo and Alexa is thanks to third-party developers and hardware. Today, Conexant and Amazon announce the AudioSmart 2-mic… [Continue Reading]

Surprise – a simple recommender system library for Python

Overview

Surprise is an easy-to-use open
source Python library for recommender systems. Its goal is to make life easier
for reseachers who want to play around with new algorithms ideas, for teachers
who want some teaching materials, and for students.

Surprise was designed with the
following purposes in mind:

Give the user perfect control over his experiments. To this end, a strong
emphasis is laid on
documentation, which we
have tried to make as clear and precise as possible by pointing out every
details of the algorithms.
Alleviate the pain of Dataset
handling.
Users can use both built-in datasets
(Movielens,
Jester), and their own custom datasets.
Provide with various ready-to-use prediction
algorithms (Neighborhood approaches, SVD, SVD++…)
Make it easy to implement new algorithm
ideas.
Provide with tools to evaluate,
analyse
and
compare
the algorithms performance. Cross-validation procedures can be run very easily.
The name SurPRISE (roughly) stands for Simple Python RecommendatIon System
Engine.

Installation / Usage

The easiest way is to use pip (you’ll need numpy):

Or you can clone the repo and build the source

What’s new on Drupal.org? – November 2016

Read our Roadmap to understand how this work falls into priorities set by the Drupal Association with direction and collaboration from the Board and community.
The engineering team at the Drupal Association had much to be thankful for in November. With the support of the wonderful volunteers in our community and the contributions of our Supporting Partners we were able to deliver some great tools for the project. Let’s dive and see what’s new.
Drupal.org updates
Promoting Drupal by Industry

In November we finished the technical scaffolding for the upcoming industry pages, and began working with the wider Association team on content development for these pages. Because we were ahead of our internal targets for this page and we felt it would add significant value, we’ve also added the ability to geotarget content on these industry pages.
This is the first instance of geo-targeting on Drupal.org, and we’ll be using it to help connect Drupal

What’s New with Xen Project Hypervisor 4.8?

I’m pleased to announce the release of the Xen Project Hypervisor 4.8. As always, we focused on improving code quality, security hardening as well as enabling new features. One area of interest and particular focus is new feature support for ARM servers. Over the last few months, we’ve seen a surge of patches from various ARM vendors that have collaborated on a wide range of updates from new drivers to architecture to security.
We are also pleased to announce that Julien Grall will be the next release manager for Xen Project Hypervisor 4.9. Julien has been an active developer for the past few years, making significant code contributions to advance Xen on ARM. He is a software virtualization engineer at ARM and co-maintainer of Xen on ARM with Stefano Stabellini.
This release also marks the start of our first 6-month release cycle. Despite the shorter timeframe and putting more thorough security processes

By Ronnie Chen and Diana PojarResearch Data Management via janneke staaks licensed under Creative CommonsFor a company like Slack that strives to be as data-driven as possible, understanding how our users use our product is essential.The Data Engineering team at Slack works to provide an ecosystem to help people in the company quickly and easily answer questions about usage, so they can make better and data informed decisions: “Based on a team’s activity within its first week, what is the probability that it will upgrade to a paid team?” or “What is the performance impact of the newest release of the desktop app?”The DreamWe knew when we started building this system that we would need flexibility in choosing the tools to process and analyze our data. Sometimes the questions being asked involve a small amount of data and we want a fast, interactive way to explore the results. Other times we
