  • The Y2038 problem in the Linux kernel, 25 years of Java, and other industry news

    As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.

  • How fast are your disks? Find out the open source way, with fio

    Storage benchmarking—much like Wi-Fi benchmarking—is a widely misunderstood black art. Admins and enthusiasts have for decades been tempted to just “get the big number” by reading or writing a large amount of data to a disk, getting a figure in MB/sec, and calling it a day. Unfortunately, the actual workload of a typical disk doesn’t look like that—and that “simple speed test” doesn’t reproduce a lot of the bottlenecks that slow down disk access in real-world systems.

    The most realistic way to test and benchmark disks is, of course, to just use them and see what happens. Unfortunately, that’s neither very repeatable, nor is it simple to analyze. So we do want an artificial benchmarking tool—but we want one that we can use intelligently to test storage systems across realistic scenarios that model our day-to-day usage well. Fortunately, we don’t have to invent such a tool—there’s already a free and open source software tool called fio, and it’s even cross-platform!

  • How the Iowa caucus app went wrong and how open source could have helped

    Opinion: It was incompetence, not politics, that led to the Iowa caucus app misfiring. Above all, it was poor programming. Open-source software techniques could have prevented this blunder.

    When the Iowa Democratic Caucus results were delayed by an application foul-up Bernie Sanders supporters were outraged at a stolen victory. Now, as the results trickle in, and Sanders' results turned out OK, they've quieted down. But the fact remains that the application not only fouled up caucus results reporting, but it also made people even less trusting of the election process.

    Most of the Iowa caucus post-mortem has focused on Shadow, the company behind the app, and its parent organization, Acronym. The root problem wasn't with the groups behind the misfiring application, IowaReporterApp; it was with a fundamentally flawed software development process.

  • Switzerland plans to anchor public services' contribution to open source in law

    Swiss federal government organisations and agencies will soon be free to share the source code of their software solutions as open source. In addition, software developers working for the federal government should be able to be part of open source communities. The government wants to anchor this in federal law, according to new Guidelines on Open Source in the Federal Government, made public last Friday.

  • Mass resignations at Wiley journal over academic independence

    The resignation of all members of a journal's editorial and advisory boards in a row over academic independence raises fundamental questions about "who owns" academic publications, scholars have claimed.

    The mass resignations at the European Law Journal -- in which a total of 20 academics linked to the Wiley publication quit -- follow more than a year of negotiations with the US publisher in the wake of its alleged effort to appoint new editors-in-chief in 2018 without consulting either its board of editors or its advisory board.

  • Bada Bing, bada bork: Windows 10 is not happy, and Microsoft's search engine has something to do with it

    Microsoft doesn't do things by halves. Not content with Teams taking the day off and Outlook labeling everything as spam, now Windows 10 Search has joined the cock-up club.

    The problem manifests itself by flinging up a large black box where search results should be on the Windows 10 desktop. Multiple flavours of Windows 10 are affected, and PCs at Vulture Central have also suddenly caught the search sickness.

    We're guessing queries are piped to Bing, which isn't responding for some reason, causing all results to not show up on desktops. In which case, we have to wonder, why is it necessary for Windows 10 to send local queries to Microsoft's backend, and why is it programmed in such a way that network failures blow away all results, including local ones?

  • Citrix ADC in OpenShift Service Mesh

    Citrix is proud and thankful to achieve Red Hat OpenShift Operator Certification. Operators enable users to deploy and manage resources in an OpenShift environment in an easier and more simplified manner. This blog post talks about various benefits of Citrix Cloud Native Stack and deployment of Citrix ADC to act as OpenShift Ingress.

  • Docker Inc. Creates Index to Track Docker Hub Usage

    Docker Inc. this week launched a Docker Hub Index that provides access to analytics based on anonymized data from 5 million Docker Hub and 2 million Docker Desktop users.

    John Kreisa, senior vice president of marketing for Docker Inc., says the company decided to create the index to illustrate how vibrant the Docker developer community remains in the wake of its restructuring to focus on workflow tools that accelerate the development of containerized applications.

    The Docker Index shows there have been 8 billion pulls from the Docker Hub in the last month alone, and a total of 30 billion overall. Docker Inc. reports there are now 6 million repositories on Docker Hub that are being accessed by 5 million users.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
