  • What’s new in Security for Ubuntu 22.04 LTS?

    Canonical Ubuntu 22.04 LTS is the latest long term support release of Ubuntu, one of the world’s most popular Linux distributions. As a Long Term Support release, Ubuntu 22.04 LTS will be supported for 10 years, receiving both extended security updates and kernel livepatching via an Ubuntu Advantage subscription (which is free for personal use). This continues the benchmark of Ubuntu LTS releases serving as the most secure foundation on which to both develop and deploy Linux applications and services. In this blog post, we take a look at the various security features and enhancements that have gone into this new release since the Ubuntu 20.04 LTS release. For a more detailed examination of some of these features, be sure to check out the previous articles in this series which cover the improvements delivered across each interim release of Ubuntu in the past 2 years between 20.04 LTS and 22.04 LTS.

  • We Still Want IBM i On The Impending Power E1050

    In March last year, as Big Blue was finishing up the development of the Power10 family of Power Systems machines, we wrote an essay explaining that we wanted IBM i to be a first-class operating system citizen on the four-socket Power E1050 machine, which we finally expect to see launch on July 12 if the rumors are correct.

  • Big Blue Tweaks IBM i Pricing Ahead Of Subscription Model

    Back in May, Big Blue said that it was going to be simplifying the IBM i stack ahead of a move to subscription pricing for systems software as well as hardware that runs it. To do that means zeroing out prices for a slew of things that had price tags on them formerly.

  • Guru: The Finer Points of Exit Points

    Many years ago, we received a call from an IBM i customer stating that all exit points were gone and the QAUDJRN and receivers were missing. Then the question, “Do you think we’ve been hacked?” Truth was, the exit points weren’t gone; the associated programs had been de-registered. Conclusion, they had most likely been compromised.

  • How to properly adopt and manage Kubernetes in production

    Kubernetes is a very important technology in the marketplace because vendors, ISVs, end users and enterprises are all able to come together and use this common infrastructure substrate to build their product on.

    In this video for Help Net Security, Alex Jones, Director of Kubernetes Engineering at Canonical, talks about properly adopting and managing Kubernetes in production.

  • Big Data on Kubernetes: The End For Hadoop?

    When data sets are too large and/or too complex for traditional software to deal with, we refer to them as ‘big data.’ Organizations and businesses around the world need to use big data to work on projects that influence the way we live now and in the future.

    Conversational AI companies want their bots to seem as natural as possible. To achieve this, they must process massive amounts of data in the most efficient and cost-effective way possible. That’s where open source ecosystems like Hadoop come in.

  • Traefik Labs Adds Hub to Simplify Container Networking - Container Journal

    Traefik Labs today unveiled a cloud service that leverages agent software to simplify the provisioning of network services for containers.

    Manuel Zapf, a product manager for Traefik Labs, says Traefik Hub is a software-as-a-service (SaaS) platform that adds an agent to the open source Traefik Proxy software. That agent makes it possible to instantly authorize access to containers from a single dashboard. That capability eliminates the need to manually configure domain name system (DNS) addresses, routing rules, access control and network access translation to gain access to the internet, he adds.

  • 8 open source Kubernetes security tools | Red Hat Developer

    Security remains a top concern for developers working with containers and Kubernetes. In a just-released paper from Red Hat, the 2022 State of Kubernetes security report, 93% of respondents experienced at least one security incident in their Kubernetes environments during the previous year. And 31% of respondents attributed revenue or customer loss to these security incidents.

    Innumerable tools exist—including intrusion detection systems, code scanners, and more—to improve security in an increasingly at-risk software development environment. Unfortunately, few of these are built with the unique risks and needs of a Kubernetes environment in mind.

  • Digital transformation: Maximize customer experience in 3 steps

    Organizations looking to improve the customer service experience have long turned to digital solutions – to great effect if done correctly. According to McKinsey, organizations that successfully leverage digital products to improve the customer experience are able to increase customer satisfaction by up to 20 percent, reduce the cost to serve by up to 40 percent, and boost conversion rates and growth by 20 percent.

    However, to truly impact and improve the customer experience, organizations need to go beyond simply purchasing a product. Research from Boston Consulting Group shows that 70 percent of digital transformation efforts fail, often for reasons that have more to do with implementation than with the actual solutions themselves.

Error resolved: 1698 (28000) Access denied for user ‘root’@’localhost’

Filed under

This error is very common when you try to log in to your MySQL for the first time.

Personally, I too faced this issue multiple times, maybe because we were not following the right way to install MySQL, or we forgot to set a password, or else we didn’t get the options to set a password.

Similarly, there may be many other reasons for the above error, but the solution to this error is pretty simple and easy. In this article, you will find a way to resolve 1698 (28000) Access denied for user ‘root’@’localhost’.

There are two ways to resolve this error. First, you will see a simple and less time-consuming method. If the first method didn’t work in your case, then go to the second one.

  • 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.
