  • Do host firewalls matter in cloud deployments?

    Cloud deployments enable incredible amounts of network flexibility for any workload. Companies build, connect, and configure networks at a rapid pace via convenient application programming interfaces (APIs). However, these easily configurable interconnections lead to situations where dangerous network paths remain open due to misconfiguration or complexity.

    Someone asked me recently if host firewalls still matter in cloud deployments. In short: they do still matter. Host firewalls, such as iptables or nftables, play a key role in a defense-in-depth strategy, and they often close gaps in critical network infrastructure. Red Hat Enterprise Linux (RHEL) includes firewalld, a firewall management framework, that delivers reasonable defaults and makes rule management easy.

    This post covers some potential scenarios where a host firewall could reduce risk in a cloud deployment.

  • Saaf Water provides insights for safe water consumption

    Many of us take for granted that clean, safe drinking water will be instantly available when we turn on a tap in our home. But 2 billion people around the world lack access to safely managed drinking water, and in order for that to change by 2030, the current rate of progress would need to double in 129 countries. The issue is especially challenging for remote communities who have to gather their drinking water from unreliable sources. Helping these communities make informed decisions about their drinking water can greatly mitigate the risks.

    For the team in India behind Saaf Water (“saaf” is a Hindi word for “clean”), the inspiration to take on the issue of clean drinking water was personal. Team member Hrishikesh saw firsthand the danger of unsafe drinking water when his mother became ill by drinking from her village’s groundwater supply that was assumed to be safe. Even though the team members are all from different villages, they all have friends or family members impacted by contaminated water. They realized that communities need data and information about their local drinking water to be able to make safe decisions about purification and consumption.

  • Honestly leads consumers to more ethical purchases

    How can you really know the environmental impact of that pair of jeans you just ordered online? Household consumption of goods contributes to over 60% of the greenhouse gases that drive climate change. Now, e-commerce is causing an increasing share of the environmental damage created by consumer goods: The UN reports that during the COVID-19 pandemic, online sales jumped from 16% to 19% of all retail sales. Individual consumers want to do the right thing and are often willing to spend a bit more to make sustainable purchases. However, it can be overwhelming to try to fully understand the ethical practices of the businesses they buy from or the environmental footprint of the products they consume.

  • Plenti cuts kitchen waste to shrink carbon footprint [Ed: IBM pretends to care about carbon footprint; same as Microsoft]

    Did you know the average household throws away 1 in 5 bags of spoiled groceries? Beyond the economic impact on households, the environmental impact is exacerbated by the fact that food products create a considerable carbon footprint from the farm, to the store, and into your kitchen before getting dumped.

    The Plenti team are looking to change this and help us better manage our groceries. As a Top Five finalist in the 2021 Call for Code Global Challenge, Plenti was developed as a mobile app that alerts you before your food goes off.

  • Project Scavenger manages e-waste for a healthier world [Ed: IBM kicked off another greenwash campaign today]

    Once an anomaly, working remotely has become a common practice for many employees over the course of the past 20 months — and it shows no sign of receding. Gartner estimates that remote workers will represent 32% of all employees worldwide by the end of 2021. While there are wide-ranging opinions surrounding the work-from-home dynamic, one objective truth is that there has been a massive increase in home office set-ups, and demand for home office devices like keyboards, mice, CPUs and more. Manufacturers are trying to keep up with this rapid increase in demand. Combine those new devices with the thousands still residing in now abandoned on-site offices, and the result is an alarming amount of e-waste.

  • Green Farm supports sustainable community agriculture

    Agriculture accounts for about one-third of global greenhouse gas emissions. While sustainable farming plays an important role in helping reduce carbon emissions and combat climate change, it still only represents a small share of all agricultural production. Community supported agriculture (CSA) has increased in popularity during recent years as an answer to this global challenge, especially during the supply chain disruptions and day-to-day hurdles consumers have faced during the COVID-19 pandemic. But the rapid growth of this type of farming model brings its own set of challenges. Small farmers struggle to ensure their planting methods are sustainable, eco-friendly, and transparent as they attempt to scale and reach new customers. It is difficult for them to experiment with alternative agricultural methods because of local volatility, both ecologically and in the market, brought on by climate change and the ongoing pandemic. Consumers, meanwhile, face uncertainty about the quality and availability of local produce.

  • Digital transformation: 7 in-demand technology skills

    The pandemic jolted businesses across the globe, forcing them to accelerate their digital initiatives – some achieved years’ worth of digital transformation initiatives in a matter of months. And with remote work in effect, organizations also had to invest in collaborative platforms for employees and self-service portals for customers to ensure business continuity.

    Organizations today continue to invest in digital transformation priorities, and the demand for those with skills in cloud, rapid application development (low code), and new-age technologies is growing. As companies compete to attract candidates who are proficient in emergent technologies, candidates with extensive experience in these areas are in a strong position to drive digital transformation initiatives, optimize costs, approach complex issues innovatively, and aid in the decision-making process.

  • How to put people at the center of digital transformation

    Many businesses saw the COVID-19 pandemic rapidly accelerate their digital transformation plans. Going digital is imperative in the new reality, characterized by hyper-connection and an ever-increasing consumption of online products and services. Even so, many still struggle to understand and apply the concept of going digital in real life.

    However, some organizations have failed in their digital transformation journey as they overlooked a fundamental aspect in these times of change ‒ the human factor.

    At first glance, it may seem odd that this is considered a factor. Still, digital transformation and innovation are related to profound human transformation. A Boston Consulting Group publication, “It’s Not a Digital Transformation without a Digital Culture,” argues that “like any major transformation, a digital transformation requires instilling a culture that supports the change while enabling the company’s overarching strategy.”

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
