How to flatten sharpening stones
Over time, sharpening stones wear more in the middle than along the edges. If you continue to sharpen in the dished area of a stone, your tools' cutting edges will have slightly rounded edges. That's why it's critical to remove the high sides.

Photos from Crude Sketches: NVIDIA's GauGAN Explained Visually - AdamDKing.com
The app builds off the deep learning–based technology of generative adversarial networks (GAN). In a pun inspired by painter Paul Gauguin, NVIDIA has named it GauGAN. Underlying GauGAN’s functionality is a new algorithm called SPADE.

Using 6 Page and 2 Page Documents To Make Organizational Decisions
A challenge of organizations is the aggregation of local information to a point where a globally optimal decision can be made in a way all stakeholders have seen their feedback heard and so can “disagree and commit on the result. This document describes Amazon's famous “6 pager” and “2 pager” document and review meeting process, as a mechanism to address this challenge.

The 5 Basic Statistics Concepts Data Scientists Need to Know
From a high-level view, statistics is the use of mathematics to perform technical analysis of data. A basic visualisation such as a bar chart might give you some high-level information, but with statistics we get to operate on the data in a much more information-driven and targeted way. The math involved helps us form concrete conclusions about our data rather than just guesstimating.

Food Discovery with Uber Eats: Recommending for the Marketplace | Uber Engineering Blog
Recommendations are based on both our modeling of each user’s taste preference through machine learning and our semantic understanding of food types. These recommendations also serve to support the overall health of the Uber Eats marketplace. Through multi-objective optimization, we can help eaters discover a diverse array of restaurants and ensure that our restaurant-partners receive a fair amount of exposure in the app based on eater interest.

Why Fastly loves QUIC and HTTP/3
QUIC (that’s not an acronym) is a brand-new internet transport protocol, replacing the most commonly used transport today, TCP. HTTP/3 is designed to take advantage of QUIC’s features. It does not change HTTP semantics (URLs and HTTP header definitions) from HTTP/2. By using QUIC, HTTP/3 should address HTTP/2’s performance issues, while avoiding application changes.

Vertically Scaling PostgreSQL - pgDash
PostgreSQL can scale rather well vertically. The more resources (CPU, memory, disk) that you can make available to your PostgreSQL server, the better it can perform. However, while some parts of Postgres can automatically make use of the increased resources, other parts need configuration changes before improvements can be noticed.

Best practice and tips & tricks to write scientific papers in LaTeX, with figures generated in Python or Matlab.
This repository contains a list of tools, best practices, tips and other guidelines we found useful/important when writing scientific papers. Some are a matter of style (we tend to follow the guidelines of the Chicago Manual of Style), and we are well aware that other people prefer to do things differently, but we list them anyway to have a consistent guide.

media.ccc.de - How to teach programming to your loved ones
Teaching beginners how to program is often hard. Showing them how to copy-paste a few example programs and change a few parameters is easy, but bridging from there to building substantial programs is a different game entirely. This talk is about how to teach programming successfully, through comprehensible design recipes, which anyone can follow, using languages and tools designed for beginners.

Performance Under Load – Netflix Technology Blog – Medium
Adaptive concurrency limits fundamentally improve how an application behaves under extreme load, and allow us to avoid cascading service failures. We have eliminated the arduous task of trying to determine the concurrency limit of a system, while ensuring that latencies remain low. With this announcement, we’re also open-sourcing a simple Java library with integrations for servlets, executors and GRPC.

This article outlines a variety of additional patterns available for REST-based APIs. The intent isn’t to be fully exhaustive, but to open the options for API designers uncertain about how to apply designs beyond CRUD to REST-based APIs.
