A remarkable pilot project installed on a 240-m (787-ft) container ship has proven it's possible to capture at least 78% of emissions from the smokestacks of cargo ships and convert the CO2 into limestone pebbles, which can be offloaded and sold.London startup Seabound, funded by a US$1.5-million grant from the UK Government, partnered up with global shipping company Lomar to install the carbon capture equipment on one of its older and dirtier-burning ships, a medium-sized vessel capable of carrying more than 3,200…

Last week, Stanley landed itself in hot water after a safety advocate went viral for pointing out that the company uses toxic lead in cups, tumblers, and other products. The internet, which spent recent months celebrating Stanleys as the must-have hot girl product, went ballistic. Stories about the leaded Stanley cups cropped up everywhere from the New York Times to the TODAY show, and Hydro Flask—Stanley’s chief competitor—seized the opportunity. Hydro Flask ran posts on social media boasting about its lead-free…

Docker Swarm is a powerful orchestration tool that allows you to manage and deploy containers in a cluster environment. It provides features for load balancing, scaling, and ensuring high availability of your containerized applications. In this comprehensive tutorial, we will walk you through the process of setting up a Docker Swarm cluster and deploying Docker containers within it. This guide assumes you have a basic understanding of Docker and containerization concepts. Introduction to Docker Swarm What Is Docker…

A practical tutorial for setting up a local dev environment using Docker ContainerImage by Tom Fask from PexelsMotivationAn essential part of a data scientist’s daily work involves managing and maintaining a development environment. Our work goes considerably more smoothly when the development environment is kept up-to-date and closely reflects the production environment; when it isn’t, things start to get messy. Proficiency with the CI/CD pipeline and devops can be quite advantageous in a larger environment. Providing…

In a new study published in Environmental Science and Technology Letters, fluorinated high-density polyethylene (HDPE) plastic containers — used for household cleaners, pesticides, personal care products and, potentially, food packaging — tested positive for PFAS. Credit: University of Notre DameScientists at the University of Notre Dame are expanding their list of consumer products that contain PFAS (per- and polyfluoroalkyl substances), a harmful group of fluorine-based compounds known as “forever chemicals.”A new study…

LONG BEACH, Calif.—Global shipping executives are wrestling with plunging exports, falling freight rates and mounting suspense over whether the industry is headed for a price war. Traffic from China’s ports has slowed significantly, empty containers are stacked six high and trucks with no cargo dot the highway leading to the major terminals. The world’s largest box-ship operator plans to return dozens of chartered vessels to their owners.  China’s exports fell nearly 10% in December from a year ago, the third…

Optimizing Container Resource Allocation with Linux Control GroupsPhoto by Joshua Hoehne on UnsplashThe last article examined how to use Linux Namespaces to create isolated environments within a single Linux system. This article is part of our effort to deeply understand how containers work by looking under the hood.Namespaces are the first step of our journey. We saw how you can create a PID namespace to create a world where the processes running within are under the assumption that they are the only ones in existence,…
