  • 10 tech freebies to grab now: Software, phone service, logos and more

    Microsoft Office is pricey. You don’t need to pay for it if you know about this free alternative: LibreOffice. It’s a free, open-source office suite compatible with Microsoft Office files. Since it’s open-source software, the program is continually updated at no charge.

    LibreOffice offers six programs that will feel instantly familiar to you if you’ve used Office before. Writer, Calc and Impress are equivalent to Microsoft Word, Excel and PowerPoint. They have most of the same features. You might need to poke around to find some of them.

    Even better, LibreOffice can open and edit the documents you made in Office and save new files in Office formats. Download Libre Office here.

  • Airbyte: The Money and Licensing of Software Plumbing

    AirByte, a basically open source startup that specializes in connectors for data channels caught the attention of venture capitalists in a big way in 2021, completing three funding rounds that raised a total of $181.2 million during the year, for a valuation of $1.5 billion. Not bad for a startup that won’t enter its second year until early 2022.

    It also seems to have avoided what could have been a kerfuffle with open sourcers with a decision to license the software that runs its SaaS platform with the Elastic License v2. This move came with the risk of generating a bit of unwanted controversy, since the license is one of a spate of licenses that have been created during the last five years or so that some are derisively calling “fauxpen source,” because they have some of the trappings of open source but are believed to not qualify for approval by the Open Source Initiative standards organization.

  • Let it snow! New: xsnow plays better with xscreensaver, see the 'settings' tab

    Xsnow has old roots and is adapting to new environments, visible in the code, which is a good thing for an application like xsnow. For example, there is no convention whatsoever for the naming of variables and functions. Something like 'windonfallensnow' can be spelled like: 'windonfallensnow', 'wind_on_fallen_snow', 'WindOnFallenSnow', WOFS and so on. The language used is C, (not C++ as would be the obvious choice now, however: see 'Technical issues' (no, not Python or Ruby: we really need some performance)), with many global variables, sometimes with not very helpful names. The choice whether a function and accompanying header files are placed is separate files or in xsnow.c, is based on the moment of the day, or the flipping of a coin. Xsnow-1.42 hardly used floating point arithmetic, xsnow-2.0 uses a mix of floating point and integer arithmetic, floating point gradually taking over. The documentation contains references to systems that are extinct for many years, but description of new flags has been noted to creep in. Xsnow's genes show traces of findent, and even of some Hitchhikers Guide. The genes for 'toon.h' are almost gone, there are at this moment better ways to find the window to snow in. The program became aware of the fact the Santa's sleigh is pulled by 8 reindeers: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder and Blixem. Later on, Rudolf could be added. It seems that some of the pixmaps are evolving in that direction.

  • FreeBSD and I2C

    I've been playing around with some I2C based sensors from SparkFun. They have QWIIC connectors making it easy to speak to them from SparkFuns OpenLog Artemis. The OpenLog Artemis can log sensor data to SD card and also presents itself as a serial device where it streams data from the sensors in a CSV-like format. It works great and I can highly recommend the whole QWIIC ecosystem.

    Occationally I need to use one of the QWIIC sensors from some FreeBSD based system, without the OpenLog Artemis. In this case I am using a Raspberry PI Zero with FreeBSD a 13-CURRENT from December. This is easy because the QWIIC system is just plain I2C underneath, so it is easy to hook a sensor up directly to the GPIO pins of the RPI with one of these.

    In FreeBSD land we have i2c(8) which is a userspace utility for reading and writing to I2C devices. I will start by going over basic usage before diving deeper into the actual sensors I am playing with in this learning session.

  • OpenBSD on MeLE Quieter2

    So I got the MeLE Quieter2Q. It ships an Intel Celeron J4125 @2.00GHz and 8GB of RAM. My model also comes with 256GB of eMMC storage and 256GB of removable M.2 NVMe/SATA 2280. And it is fanless.

    Installation when straightforward. Simply plug the machine to an HDMI monitor (I used my Samsung TV), connect a keyboard (I used an wireless Logitech keyboard) and a USB stick were install70.img was transferred.

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.
