Install MultiPass on Ubuntu : A good VM Manager - LinuxTechLab
Multipass is a very lightweight VM manager that can be used to launch & manage VMs with a single Linux command. It is available on Linux, macOS as well as Windows. On Windows, it used Hyper-V, on Linux, it uses KVM & on Mac it used HyperKit.
It can simulate a cloud environment with the support of cloud-init. It helps to create a new development or testing environment with ease. It also supports VirtualBox on macOS & Linux also. In this tutorial, we will learn how to install Multipass on Ubuntu

How to install Java on Manjaro Linux
Many developers and programmers choose Manjaro because it's one of the most user-friendly and feature-rich Linux distributions. In this guide, we go over the steps to install the Java Development Kit on Manjaro Linux. We'll show you how to install both the OpenJDK package (which is free and GPL-licensed) as well as Oracle Java SE Development Kit.
Arch Linux and Manjaro only officially support the OpenJDK, as that is the non-proprietary version. However, the Oracle package can be installed from the AUR, as you'll see shortly.

Arduino IDE contains an editor that is used for writing and uploading programs to the Arduino board. Before start to create projects through Arduino, the user needs to set up an IDE for the programmable board.
In this article, we will learn how to install the latest Arduino IDE on CentOS 8.

Vincent Fourmond: QSoas tips and tricks: generating smooth curves from a fit
Often, one would want to generate smooth data from a fit over a small number of data points. For an example, take the data in the following file. It contains (fake) experimental data points that obey to Michaelis-Menten kinetics: $$v = \frac{v_m}{1 + K_m/s}$$ in which \(v\) is the measured rate (the y values of the data), \(s\) the concentration of substrate (the x values of the data), \(v_m\) the maximal rate and \(K_m\) the Michaelis constant.
[...]
Now, with the fit, we have reasonable values for \(v_m\) (vm) and \(K_m\) (km). But, for publication, one would want to generate "smooth" curve going through the lines... Saving the curve from "Data.../Save all" doesn't help, since the data has as many points as the original data and looks very "jaggy" (like on the screenshot above)... So one needs a curve with more data points.

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. |
