Linux: Windows Embracing Ubuntu

In the past, Microsoft has had an reluctant view on its competitors, such as the Linux and open source communities. Linux has put in huge effort to make it Windows-compatible, but those efforts hasn't been mutual.

Over the last years, Microsoft has changed its approach to the open source community. I assume that it is a pragmatic decision - Windows is still dominating the desktops, but nowadays there are many more areas where Windows hasn't been able to compete with Linux, such as servers, smart phones and embedded systems.

Windows Subsystem for Linux
A couple of years ago, Microsoft introduced Windows Subsystem for Linux. It is a compatibility layer that makes it possible to run a Linux distribution inside a virtual machine in Windows (WSL 2). Currently, it is configured for command-line applications only, but there are web sites describing how to setup an X- server for WSL 2.

As it is possible to reach all files in Windows from the Linux VM, and also to reach the home folder from Windows, it is easy to modify files and scripts.

Installation
Microsoft has an excellent installation guide for WSL.

1. Ensure that you are using a new version of Windows 10. You want to have Windows build 18917 or higher to run WSL 2.
   
2. Enable Viritualization on the computer. In my case, those settings were already enabled. 
3. Enable Windows Subsystem for Windows. In Power Shell, run:  Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
4. Install WSL 2 from PowerShell
   
5. Install a Linux Distribtion of choice from Microsoft Store
6. Wait for Microsoft to develop GUI support on WSL 2

In Linux, Windows drives can be found at /mnt/ . In Windows, the root of the Linux file system can be found at \\wsl$\<distribution name>. In my case. the distribution name is ubuntu.  More info here.

Roadmap for WSL
Microsoft has announced that they intend to add support for GUI apps on WSL 2. That will be very useful.

Embrace. Extend and Extinguish?
There is a discussion about whether WSL is a way for Microsoft to embrace Linux in order to take over it. Even I have had concerns and some hostility towards Microsoft in the past, but in this case, I am not to concerned. My understanding is that Microsoft has had a change-of-hearts towards Linux.

Adding WSL/Linux is a way for Microsoft to stay relevant and prevent developers from leaving Windows entirely.

After all, WSL 2 introduced a full Linux kernel (WSL was a translation layer). This is a step towards more Linux.

Linux is still dominant when it comes to servers, embedded systems and Android. Microsoft had an attempt to enter the smartphone market but gave up its development in 2017.

UNIX/Linux has a strong position as a development environment, and as Linux distributions are getting more user friendly, and as applications are moving to web servers, Microsoft may face a challenge to keep people and developers to stay on their platform. Allowing the user to have both may be one way to keep the users. Simplifying Linux on Windows is an important step for Microsoft to stay relevant for developers.

Time will tell what influence Microsoft will have over the Linux ecosystem.

StockAnalyzer: Resuming Transmission

After focusing on global pandemics and relocations for the last months, I am able to resume focusing on my pet projects, but at a slower pace than before. I expect to post at least once per month.

I'll continue coding for the machine learning project StockAnalyzer.

Earlier this year, I explored NodeJS. I'll switch to Python instead, since it is more flexible and since I'm more familiar with it.

StockAnalyzer
I'll document the project in a separate page on the blog. The source code is available on my GitHub page.

StockAnalyzer will both present a number of graphs of how some key numbers are evolving over time.

StockAnalyzer will also perform an automated scan of all key numbers for all records over time in order to detect flawed data, where the data formats are OK, but the numeric values appear to be invalid. This will be done later.

Here, some key numbers are shown over time.
The graphs will help me find outliers and understand the data.

The first step is to present the data graphically - the vast amount of data will make it impossible to just look at the numbers.

Several of the curves appear to have identical shapes. The curves that relates the price to the earnings and capital will be similar to the price curve. This because the earnings and capital per share doesn't change very often. The yield is the dividend divided by the price and that is inversely correlated to the stock price.

In the next blog posts, I'll keep exploring the data.
