  • Krita Interview with Chris Tallerås

    My name is Chris Tallerås and I’m a 23 year old dude from the Olympic city of Lillehammer in Norway and I do political activism traveling the country to fight the climate crisis and to advocate free culture/free, libre & opensource software in our kingdom.

  • IPFire 2.23 - Core Update 134 ready for testing

    The Linux kernel was vulnerable for two DoS attacks against its TCP stack. The first one made it possible for a remote attacker to panic the kernel and a second one could trick the system into transmitting very small packets so that a data transfer would have used the whole bandwidth but filled mainly with packet overhead.

    The IPFire kernel is now based on Linux 4.14.129, which fixes this vulnerability and fixes various other bugs.

  • The need of US OSS for the programs [Ed: What an awful article. Original? Plagiarism? Even the encoding is all wrong.]

    A wide range of sorts of OSS licenses exist. In any case, there are basic traits among most OSS licenses. Two of the principle normal qualities are that: (1) beneficiaries can uninhibitedly utilize, change and convey the product; and (2) the source code (for example the comprehensible code) is made accessible to empower the activity of these rights. This recognizes OSS from restrictive programming. With exclusive programming licenses, ordinarily duplicating, altering or redistributing is disallowed and just the item code (i.e., the machine meaningful code or 'gathered structure') is circulated. The centrality of this is to adequately adjust the product, an engineer commonly would need access to the source code.

  • Certified Kubernetes Administrator (CKA) Exam and Courses Are Now Offered Onsite in China in Local Language

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today is announcing the availability of Certified Kubernetes Administrator (CKA) exam and corresponding Kubernetes Fundamentals course as in-country, instructor-led programs taught in Chinese.

    According to a Cloud Native Computing Foundation survey, 44 percent of Mandarin respondents are deploying Kubernetes. There is great demand in China and the overall Asia/Pac region for training courses that will help developers accelerate their work with Kubernetes and associated technologies.

    Since launching in 2017, the CKA exam has been taken by nearly 10,000 professionals around the world. Now it will be easier for Chinese users to take advantage of this offering with in-person instructors and in their local language. To register for the exam and courses, please visit: http://training.linuxfoundation.cn/

    “The Kubernetes administrator courses and certified exam are among the most popular training courses we offer,” said Clyde Seepersad, general manager, Linux Foundation training. “We’re now able to make the courses and exam available in Chinese with in-country exam delivery and instructors, which we hope will increase access and opportunity to learn and apply one of today’s most relevant and pervasive open source technologies.”

  • Harnessing hybrid cloud for HPC

    As a grizzled veteran of the IT industry, I have been involved in many high performance computing (HPC) projects over the years, both from a hardware and software perspective. I have always found them to be intensely interesting mainly because the projects were deeply scientific in nature, whether it be decoding the human genome, designing better, more efficient vehicles or even deep space research.
    What’s different now is the emergence of HPC into the mainstream. Instead of it just being the preserve of academics, scientists and other boffins, normal commercial organisations are trying to harness the power of HPC to solve their business issues, notably through its application to AI and Machine Learning.
    As today’s technology creates vast hordes of unstructured data, unlocking the business value therein has become a key competitive advantage and almost the Holy Grail of Digital Transformation for many organisations. HPC has a key part to play in this as deriving insight from large data sets has been a major component of scientific research for many years.

  • Building Nonstop Data Access

    The traditional way we think of data is as something that’s stored and then used later, like electricity in batteries. But today, data is always flowing, and constantly in use, much more like the electricity you pull from a grid than the energy you store in a battery. In the old days, you could wait a day, even a week, to get ahold of data. Today, it needs to be there at the flip of a switch.

  • Asteroids, SUSE and Protecting the Planet

    Asteroid Day is a global awareness campaign where people from around the world come together to learn about asteroids, the impact hazard they may pose, and what we can do to protect our planet, families, communities and future generations from future asteroid impacts. Asteroid Day takes place on June 30, the anniversary of the largest impact in recent history, the 1908 Tunguska event in Siberia. That asteroid decimated about 800 square miles (to put that in perspective, greater London is about 600 square miles). It’s estimated that a Tunguska-level “city-killer” asteroid hits the Earth every 500 years. So, while there is nothing to lose sleep over, it’s imperative that we are aware and have a plan.

  • Microsoft bans its employees from using Slack, Google Docs, and more

    Keeping your company's data safe can be tricky when your competitors are begging you to put all your conversations, projects, and hard work right into the palms of their hands.

    To make sure its competitors aren't able to look behind its tightly drawn curtains, Microsoft has a list of online services that it forbids its workforce to use, according to a report from GeekWire. They're familiar names for most modern professionals: Slack, Google Docs, and Amazon Web Services (among others).

    Despite the popularity of some of these services that allow for easy communication between employees and data storing and sharing, Microsoft wants to make sure everybody is keeping all their information in-house with its own programs. Actually, not even all of its own programs are safe, as the Microsoft-owned GitHub is also off limits.

  • [Mozilla] Emily Dunham: More on Mentorship

    Last year, I wrote about some of the aspirations which motivated my move from Mozilla Research to the CloudOps team. At the recent Mozilla All Hands in Whistler, I had the “how’s the new team going?” conversation with many old and new friends, and that repetition helped me reify some ideas about what I really meant by “I’d like better mentorship”.

  • 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.
