The Simplicity of Making Librem 5 Apps
The “quick start” video below that I made for the Librem 5 developers documentation demonstrates how quickly you can get up and running with making your own GTK applications on a Librem 5.
In this video, I have attached a Librem 5 to an external keyboard, mouse and monitor through a USB-C hub, and I use GNOME Builder to quickly create a new GTK application project, build it and run it on both the big desktop monitor and the small mobile screen with just a drag and drop across the screens.
Yes, I do all that with the computing power of the Librem 5 only! There are no special effects nor a hidden desktop computer. I even did the screencast recording with an external device so it shows the real speed of the Librem 5 when driving a 32″ Full HD monitor.

Stream event data with this open source tool
An event stream is a pipeline between a source you define and a destination of your choice. Rudderstack provides you with SDKs and plugins to help you ingest event data from your website, mobile apps, and server-side sources — including JavaScript, Gatsby, Android, iOS, Unity, ReactNative, Node.js, and many more. Similarly, Rudderstack's Event Stream module features over 80 destination and warehouse integrations, including Firebase, Google Analytics, Salesforce, Zendesk, Snowflake, BigQuery, RedShift, and more, making it easy to send event data to downstream tools that can use it as well as build a customer data lake on a data warehouse for analytical use cases.

Linux Fu: Shell Script File Embedding | Hackaday
You need to package up a bunch of files, send them somewhere, and do something with them at the destination. It isn’t an uncommon scenario. The obvious answer is to create an archive — a zip or tar file, maybe — and include a shell script that you have to tell the user to run after unpacking.
That may be obvious, but it assumes a lot on the part of the remote user. They need to know how to unpack the file and they also need to know to run your magic script of commands after the unpack. However, you can easily create a shell script that contains a file — even an archive of many files — and then retrieve the file and act on it at run time. This is much simpler from the remote user’s point of view. You get one file, you execute it, and you are done.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe 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. |
