A Hacker’s Guide to Efficiently Train Deep Learning Models

Three months ago, I participated in a data science challenge that took place at my company. The goal was to help a marine researcher better identify whales based on the appearance of their flukes. More specifically, we were asked to predict for each image of a test set, the top 20 most similar images from the full database (train+test).

Millions of tiny databases

The Physalia configuration store for chain replication of EBS is implemented as key-value stores maintained over a large number of these cells. They built a test harness, called SimWorld, which abstracts networking, performance, and other systems concepts. The goal of this approach is to allow developers to write distributed systems tests, including tests that simulate packet loss, server failures, corruption, and other failure cases, as unit tests in the same language as the system itself.

Hi! I’m one of Embox RTOS developers, and in this article I’ll tell you about one of the typical problems in the world of embedded systems and how we were solving it. Control and responsibility is a key point for a wide range of embedded systems.

Cloudflare’s Current Expansion Is Different from the Others

The company is expanding its US network in a big way, and it’s turned to two edge data center startups for help. In January, Cloudflare, which helps companies make their web services run faster and be more secure – and which more recently started to use its global data center network to also provide cloud computing services – said it would expand the network in the US with three dozen new locations. Shortly thereafter, the company said it would add even more locations in the US – about the same amount as in the first announcement.

New Kubernetes 1.18 Extends Ingress

Last month, the Kubernetes team released Kubernetes 1.18, which extended Ingress. The two most exciting features include a new IngressClass resource and the new pathType field. To minimize the risk for our users who want to try out these exciting new features, the Ambassador Edge Stack supports the latest version of the Kubernetes Ingress specifications.

A Deep Dive into PostGIS Nearest Neighbor Search

In this post, we’re going to take a deeper dive into the Postgres and PostGIS internals to find out how this actually works. By the time we surface you will have a better understanding of the advanced technical capabilities and unparalleled extensibility of Postgres. You’ll also appreciate how the open philosophy of Postgres has fostered a development community whose collaboration over many years has provided powerful features that benefit numerous users.
