  • The State of Robotics – January 2020

    Last month the TechRepublic came out with an article dubbing ROS the “hottest thing in robotics […] you’ve never heard of.” This feels like an excellent step in the right direction, moving beyond academics and into the mainstream. Of course, if you’re reading this it’s likely you have heard of ROS before, and given the size of the community, we hardly agree with the “you’ve never heard of” part. But more exposure, more adoption, more contributions to ROS, is only going to be a good thing.

    The article also links to another entitled “The 8 Coolest Robots Spotted at CES 2020.” CES, the consumer electronics show, is an annual show for consumer technologies in Las Vegas. It’s a chance for innovators and new technologies to take the stage and prove themselves in the industry. Typically it’s very saturated with lots of new technologies and it’s hard to make a mark, but it’s good to see publicity around consumer robotics coming out. One in particular that caught my attention was MarsCat. A bionic cat, home robot. As of publishing this blog the folks behind MarsCat still have time on their Kickstarter too, in case you’re the backing type.

  • Introducing a cheat sheet for open source software alternatives

    It can be frustrating when a mainstream software tool is proprietary. This is a common problem at work. Many companies default to Slack for chat, Adobe Photoshop for creative editing, and Salesforce for customer relationship management. We are faced with this issue at home, too. Our friends and family are likely to use the most popular social media platforms which tend to be closed source. With tax season coming up here in the United States, we are reminded that the go-to home finance software is proprietary.
    Luckily, we do not need to be bound by the constraints of proprietary software. There are tons of open source software alternatives to meet arguably every demand. If there isn't one already out there, someone (maybe you!) is bound to create one. One of the many benefits of choosing open source technology is that it is supported by the community. There's bound to be someone else out there eager to lend a new user a helping hand.

  • The Top 10 Free and Open Source HR Technology Solutions

    Searching for HR technology solutions can be a daunting (and expensive) process, one that requires long hours of research and deep pockets. The most popular HR tech tools often provide more than what’s necessary for non-enterprise organizations, with advanced functionality relevant to only the most technically savvy users. Thankfully, there are a number of free and open source HR technology solutions out there. Some of these solutions are offered by vendors looking to eventually sell you on their enterprise product, and others are maintained and operated by a community of developers looking to democratize HR tech.

    Let’s examine free and open source HR technology solutions, first by providing a brief overview of what to expect and also with short blurbs of the options currently available in the space.

  • Daniel Stenberg: Rockbox services transition

    Remember Rockbox? It is a free software firmware replacement for mp3 players. I co-founded the project back in 2001 together with Björn and Linus. I officially left the project back in 2014.

    The project is still alive today, even of course many of us can’t hardly remember the concept of a separate portable music player and can’t figure out why that’s a good idea when we carry around a powerful phone all days anyway that can do the job – better.

    Already when the project took off, we at Haxx hosted the web site and related services. Heck, if you don’t run your own server to add fun toy projects to, then what kind of lame hacker are you?

    None of us in Haxx no longer participates in the project and we haven’t done so for several years. We host the web site, we run the mailing lists, we take care of the DNS, etc.

    Most of the time it’s no biggie. The server hosts a bunch of other things anyway for other project so what is a few extra services after all?

  • 6 open educational resources for learning Spanish

    My goal for 2020 is to improve my Spanish, and I intend to use the open educational resources described below to help me along my long path towards fluency. These suggestions are by no means an exhaustive list of resources for learning Spanish. The items included are all open resources, which means they are either shared under an open license or are in the public domain.

    You should also consider using resources that are not open but are free, such as books in Spanish from your local library, videos on YouTube and similar sites about topics that interest you or that are designed for people learning Spanish, and anything else you can access that will increase your exposure to the Spanish language.

  • Gunnar Wolf: Migrated to Jekyll

    My blog remained with JAWS for four years, but by February 2008, I decided to switch over to Drupal 5; I needed to properly evaluate it in order to use it at work, so I migrated my blog to use Drupal instead. And behold! You can still look at my half-decent and quite long (and specific to my site) JAWS to Drupal 5 migration script!

    The upgrade to Drupal 6 was quite uneventful. I don’t remember (and cannot find) when it happened, but it didn’t scare or scar me forever. But, even when I most embraced Drupal 7 (I adopted the Debian packages in 2013, and have kept it at least up to date with the each time less frequent updates), I never got around to do the 6→7 migration on my personal website. Yes, because I don’t want to migrate a sh!tload of posts by hand… And could not be bothered to produce a script to decently replicate the whole thing.

  • Best Open Source eCommerce Platforms to Build Online Shopping Websites

    In an earlier article, I listed some of the best open-source CMS options available out there. These CMS software, as the name suggests, are more suitable for content focused websites.

    But what if you want to build your own online shopping websites? Thankfully, we have some good open source eCommerce solutions that you can deploy on your own Linux server.

    These eCommerce software are tailored for the sole purpose of giving you a shopping website. So they have essential features like inventory management, product listings, cart, checkout, wishlisting and option to integrate a payment solution.

  • 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.
