Zstandard - Real-time data compression algorithm
Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder (see benchmarks below). It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set. Zstandard library is provided as open source software using a BSD license.

guetzli: Perceptual JPEG encoder
Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer.

USB-C Compliant Cables
Not all usb-c cables are created the same. Benson Leung at Google has reviewed numerous cables, and there are quite a few non-compliant cables. These cables can result in weird, or even dangerous behavior.

If you have a Nexus 6p, Nexus 5x, or a OnePlus 2, I highly recommend using cables from the following list to save yourself trouble. All cables listed below have been reviewed, and are fully compliant with the USB-C standard.

Why Github can't host the Linux Kernel Community
The problem is that github doesn’t support the way the linux kernel scales out to a huge number of contributors, and therefore we can’t simply move, not even just a few subsystems. And this isn’t about just hosting the git data, that part obviously works, but how pull requests, issues and forks work on github.

Docker vs. Kubernetes vs. Apache Mesos: Why What You Think You Know is Probably Wrong - Mesosphere
While all three technologies make it possible to use containers to deploy, manage, and scale applications, in reality they each solve for different things and are rooted in very different contexts. In fact, none of these three widely adopted toolchains is completely like the others.

Instead of comparing the overlapping features of these fast-evolving technologies, let’s revisit each project’s original mission, architectures, and how they can complement and interact with each other.

This repository contains multiple implementations of the same 3D scene, using different APIs and frameworks on various platforms. The goal is to provide a comparison between multiple rendering methods. This is inherently biased due to the variety of algorithms used and available CPU/GPU configurations, but can hopefully still provide interesting insights on 3D rendering.

An end to end tutorial of a machine learning pipeline
This tutorial tries to do what most Most Machine Learning tutorials available online do not. It is not a 30 minute tutorial which teaches you how to "Train your own neural netowrk" or "Learn deep learning in under 30 minutes".

It's a full pipeline which you would need to do if you actually work with machine learning - introducing you to all the parts, and all the implementation decisions and details that need to be made.

The dataset is not one of the standard sets like MNIST or CIFAR, you will make you very own dataset. Then you will go through a couple conventional machine learning algorithms, before finally getting to deep learning!

Kafka Message Queue (softwaremill/kmq)
Using kmq you can acknowledge processing of individual messages in Kafka, and have unacknowledged messages re-delivered after a timeout.

This is in contrast to the usual Kafka offset-committing mechanism, using which you can acknowledge all messages up to a given offset only.

If you are familiar with Amazon SQS, kmq implements a similar message processing model.

FSArchiver - Filesystem Archiver for Linux
FSArchiver is a system tool that allows you to save the contents of a file-system to a compressed archive file. The file-system can be restored on a partition which has a different size and it can be restored on a different file-system. Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive.
