  • Five reasons why researchers should learn to love the command line

    During his postdoctoral studies, Casey Greene’s adviser insisted that all images of figures that were used in presentations had a black background. Greene got pretty good, he says, at opening figures in an image editor, inverting and colour-rotating them, and repeating. “But at some point, it turns out life is too short to continue importing and colour-rotating in even a free software program that is relatively easy to use,” says Greene, who now directs the Center for Health Artificial Intelligence at the University of Colorado School of Medicine in Aurora. So, he turned to the command line — specifically, the free and open-source image-manipulation tool ImageMagick, using a for loop to repeat the operation across all his files:

  • The start of a crazy journey: the SunFire V245

    I have a lot of learning to do here, since the server world is not a place I have ever really visited. I’m going to make stumbles along the way, but the end goal is for this server to be a usable workstation – most likely running either Linux or BSD.

    Migrating from HTTP to HTTPS is streamlined
    Switching a WordPress site from HTTP to HTTPS has proven to be a pain for all involved. While on the surface, the Site Address and WordPress Address have to be updated, content with embedded HTTP URLs remains unchanged in the database. With this release, migrating a site to HTTPS is now a one-click interaction. URLs in the database are automatically replaced when the Site and WordPress Address are both using HTTPS. Also, Site Health now includes an HTTPS status check.

    Standardize colors used in WP-Admin CSS to a single palette
    This change collapses all colors used in the CSS to one of the available shades of blue, green, red, yellow, grey, black, and white. The palette makes it simpler than ever to build components your users can read, because half the range gives you great contrast with white type and a half with black, according to current accessibility guidelines.

  • Why Firefox for Android logs you out of everything all the time

    I’ve been increasingly frustrated with Firefox for Android, my preferred mobile web browser. I’ve repeatedly had to re-login to some websites and had various problems with cookies since last year’s release of the new Firefox codenamed “Daylight.” Websites forget me between each visit and I get the “new visitor” experience every time. I finally worked out what’s going wrong.

    I’ve suspected that it might have been a side-effect of Firefox’s tracking-cookie-blocking features. I’ve just assumed the issues have been caused by short-lived session cookies, limited device storage space, perverse incentives to give me new opportunities to consent to tracking cookies, and I’ve made other excuses for the buggy behavior.

  • SODA Foundation and SNIA to Advance Education for Data and Storage Management

    In a move that advances a common goal of increasing education for a unified framework and standardization for data and storage management, the SODA Foundation and Storage Networking Industry Association (SNIA) are pleased to announce they have entered into a marketing alliance.

    The SODA Foundation is an open source project under the Linux Foundation that seeks to foster an ecosystem of open source data management and storage software for data autonomy, while SNIA is dedicated to developing standards and education programs to advance storage and information technology.

    “Working with SNIA in a marketing capacity is an ideal stepping stone to combining our expertise for the advancement of storage management technology,” said Steven Tan, VP & CTO, Futurewei and SODA Foundation Chair. “Together, we will contribute to creating a more engaged and informed developer ecosystem and emphasize the importance of the standardization of storage management APIs.”

  • Why There’s Hard, Cold Cash For Soft, Disaggregated Routing

    The appetite for such open networking – and we did not say open source networking, but that is an important subset of open networking that may not make a big difference in the longest of runs – is increasing, and it is happening at an increasing rate. But network operators are a conservative bunch, and given the nature of the job – you can lose a few nodes here and there in a datacenter and you recover, but you can’t lose the network or the whole business is hosed – you can appreciate that. There is an appetite for both open switching and open routing, and while we have talked about open switches for a long time, we are just coming around to the need for open routing as credible companies are emerging to take on these tasks.

    Open networking has the same chicken and egg problem that open serving did back in the late 1980s and early 1990s, and it took a good recession or two and the dot-com boom to get everyone on board with running some flavor of Unix on top of a RISC processor that offered better bang for the buck than the proprietary systems of the time. The hardware has to come first, and then the software moves onto it and drives the total cost of ownership down relative to fully proprietary solutions. This is ever the way in IT. It started happening with whitebox switching in a big way a decade ago, although no single network operating system has yet emerged here, and it is most definitely happening right now with whitebox routing as Arrcus, DriveNets, Volta Networks, and the open source FRR project take on routing in their own unique ways.

  • Hungary and Open Source: the Digital Success Programme 2030 [iophk: “The Hungarian DSSP is not a new operating system but simply a new GNU/Linux distro. Join up wrote an incorrect summary. It looks like some Debian derivative.”]

    In the wake of the Digital Success Programme 2030 implementation, the Ministry of Innovation and Technology has supported several Hungarian SMEs to develop a new Open Source (OSS) operating system.

  • Digital Success Software Package

    Digital Success Software Package is a collection of an operation system and several user software in Hungarian language that is free to download and to use. It is supposed to substitute those document and spreadsheet editor, web browser, email client and other office software that require subscription to use them. The Digital Success Software Package represents a software package that is easily accessible for everyone, is supported by the government and enables its users to manage their public administration affairs electronically while also being in line with modern user experience trends.

  • Jonathan Carter: Free Software Activities 2021-01

    Yikes, my head is still spinning from what a crazy month January was. Only managed to squeeze in a few uploads. I’ve also been working on an annual DPL summary that I got to about 80% in December and was barely able to touch it during January, might end up simplifying it just so that I can get it released. In the meantime there’s a lot of interesting stuff happening, stay tuned Smile

  • Outreach, Survey Extension Addressed in Second Meetup

    The second session of the openSUSE Project’s meetup regarding the End of the Year Survey Results on Jan. 30 led to some changes with regard to future surveys and contributors are looking to enhance outreach.

    The two-hour meetup took place on openSUSE’s Jitsi instance and several community members around the globe provided input on the results and how to improve the project’s diversity as well as global use.

    The group spent time discussing the projects’ weaknesses and strengths based on the survey results and commonly understood areas members hope to improve.

  • Julian Sparber: NlNet grant for Fractal

  • 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.
