TiDB is an open source NewSQL database released under the Apache 2.0 License. Because it speaks the MySQL protocol, your existing applications will be able to connect to it using any MySQL connector, and most SQL functionality remains identical (joins, subqueries, transactions, etc.). Step under the covers, however, and thereare differences. If your architecture is based on MySQL with Read Replicas, you’ll see things work a little bit differently with TiDB. In this post, I’ll go through the top five key differences I’ve found between TiDB and MySQL. With MySQL, it is common to scale-out via replication.

AWS CloudFormation supports you in your efforts to implement Infrastructure as Code (IaC). You can use a template to define the desired AWS resource configuration, and then use it to launch a CloudFormation stack. The stack contains the set of resources defined in the template, configured as specified. When you need to make a change to the configuration, you update the template and use a CloudFormation Change Set to apply the change. Your template completely and precisely specifies your infrastructure and you can rest assured that you can use it to create a fresh set of resources at any time. That’s the ideal case!

Airbnb serves millions of guests and hosts in our community. Every second, their activities on Airbnb.com, such as searching, booking, and messaging, generate a huge amount of data we anonymize and use to improve the community’s experience on our platform. The Data Platform Team at Airbnb strives to leverage this data to improve our customers’ experiences and optimize Airbnb’s business. Our mission is to provide infrastructure to collect, organize, and process this deluge of data (all in privacy-safe ways), and empower various organizations across Airbnb to derive necessary analytics and make data-informed decisions from it. The primary way high-level analytics is exposed and shared within the company is through various dashboards. A lot of people use these dashboards every day to make various decisions.

The AWS cloud provider for Kubernetes enables a couple of key integration points for Kubernetes running on AWS; namely, dynamic provisioning of Elastic Block Store (EBS) volumes, and dynamic provisioning/configuration of Elastic Load Balancers (ELBs) for exposing Kubernetes Service objects. Unfortunately, the documentation surrounding how to set up the AWS cloud provider with Kubernetes is woefully inadequate. This article is an attempt to help address that shortcoming.

Node is one of the most popular languages for microservices. With the rise of Kubernetes, increasingly, Node developers are being asked to deploy their services to a Kubernetes cluster. But what’s required to safely deploy and run Node services on Kubernetes? In this post, we focus on one specific, but vital, component: how do I understand what’s happening with my Node service on Kubernetes, and how do I debug it when things go wrong? At this point, you may be thinking, can’t I just use the Kubernetes dashboard? Unfortunately,while Kubernetes can automatically keep your service up in the event of node failure or a software crash, it doesn’t actually know whether your service is behaving correctly.

Speaker diarization, the process of partitioning an audio stream with multiple people into homogeneous segments associated with each individual, is an important part of speech recognition systems. By solving the problem of “who spoke when”, speaker diarization has applications in many important scenarios, such as understanding medical conversations, video captioning and more. However, training these systems with supervised learning methods is challenging — unlike standard supervised classification tasks, a robust diarization model requires the ability to associate new individuals with distinct speech segments that weren’t involved in training.

Note that this guide was written in November 2018 to complement an in-depth conversation on the 80,000 Hours Podcast with Catherine Olsson and Daniel Ziegler on how to transition from computer science and software engineering in general into ML engineering, with a focus on alignment and safety. If you like this guide, we’d strongly encourage you to check out the podcast episode where we discuss some of the instructions here, and other relevant advice. Technical AI safety is a multifaceted area of research, with many sub-questions in areas such as reward learning, robustness, and interpretability.

In this manifesto, we will give a specific definition of what REST is, according to Roy, and see the majority of APIs and API specs (JSONAPI, HAL etc) fail to follow this model. We will see what problems a RESTful API brings and why API designers have been constantly avoiding using it but instead come up with half-way solutions or retreat to alternative models like RPC-over-HTTP or, lately, GraphQL. Then, we will propose a new model, Introspected REST, that solves the issues that REST creates and allows the design of progressively evolvable APIs, in a much simpler way than conventional REST.

We have CNI as a common standard in Kubernetes and all these plugins need to do is assign an IP address to each pod so they can talk to each other, […] The most complicated comparison I’ve ever attempted. From a 10,000 ft perspective it should be simple. We have CNI as a common standard in Kubernetes and all these plugins need to do is assign an IP address to each pod so they can talk to each other, both on the same host, and across hosts.

Convolutional Neural Network models, or CNNs for short, can be applied to time series forecasting. There are many types of CNN models that can be used for each specific type of time series forecasting problem. In this tutorial, you will discover how to develop a suite of CNN models for a range of standard time series forecasting problems. The objective of this tutorial is to provide standalone examples of each model on each type of time series problem as a template that you can copy and adapt for your specific time series forecasting problem. After completing this tutorial, you will know: How to develop CNN models for univariate time series forecasting. How to develop CNN models for multivariate time series forecasting.
