  • How to Plot a Histogram with Pandas in 3 Simple Steps

    The post How to Plot a Histogram with Pandas in 3 Simple Steps appeared first on Erik Marsja.

    In this post, we are going to learn how to plot histograms with Pandas in Python. Specifically, we are going to learn 3 simple steps to make a histogram with Pandas. Now, plotting a histogram is a good way to explore the distribution of our data.

  • Python Community Interview With Brett Slatkin

    Today I’m speaking to Brett Slatkin, a principal software engineer at Google and the author of the Python programming book Effective Python. Join us as we discuss Brett’s experience working with Python at Google, refactoring, and the challenges he faced when writing the second edition of his book. Without any further ado, let’s get into it!

  • World's average country population and inspection paradox

    Have you ever thought how much is the world’s average country population? And what does it say about the country you are living in or for the quality of life of the average person? All these questions are related to what we call the “Inspection Paradox” which we are going to illustrate here using Python.

    First of all we need to find some data. For that purpose we could use wikipedia. We are going to do everything without even opening a web browser! There is a nice Python library we could use to access and parse data from Wikipedia. In order to install it we need to simply run.

  • Is Switching From Python to Java is a Good Idea?

    The idea of having Python as a first programming language has a rational background. First of all, the syntax of Python is short and clear and the underlying model of objects and variables working is perfectly consistent. That means you can write “real” and pretty powerful applications without great effort. So there is nothing strange that many schools teach students programming using Python.

    However, knowing two languages is always better than one. If you are thinking of learning a second language after Python, Java could be a really nice choice. In this article, we are going to discuss switching from Python to Java in the case of a beginner software developer.

  • How to use wall command in linux - Unixcop

    wall is (an abbreviation of write to all) is a Unix command-line utility that displays the contents of a computer file or standard input to all logged-in users. It is used by root to send out shutting down message to all users just before poweroff. It displays a message on the terminals of all logged-in users. The messages can_be either typed on the terminal or the contents of a file. Also usually, system administrators send messages to announce maintenance and ask users to log out and close all open programs.The messages ‘re shown to all logged in users with a terminal open.

    When IT and Security professionals talk about port numbers, we’re referring to the TCP and UDP port numbers a service is running on that are waiting to accept connections. But what exactly is a port?

  • Book Review: Data Science at the Command Line By Jeroen Janssens

    Data Science at the Command Line: Obtain, Scrub, Explore, and Model Data with Unix Power Tools written by Jeroen Janssens is the second edition of the series “Data Science at the Command Line”. This book demonstrates how the flexibility of the command line can help you become a more efficient and productive data scientist. You will learn how to combine small yet powerful command-line tools to quickly obtain, scrub, explore, and model your data. To get you started, author Jeroen Janssens provides a Docker image packed with over 80 tools–useful whether you work with Windows, macOS, or Linux.

  • How to Take a Typing Test on Linux With tt

    In the modern era of technology, typing has become one of the most common activities for a lot of professions. Learning to type faster with accuracy can help you get more things done in the same amount of time. However, touch typing is not a skill that you can master overnight. It takes regular practice and testing to improve your speed and accuracy gradually. While there are a lot of websites that help you achieve this, all you essentially need on Linux is a terminal. Let's see how.

Security and DRM Leftovers

Linux 5.15-rc3

So after a somewhat rocky merge window and second rc, things are now
actually looking pretty normal for rc3. Knock wood.

There are fixes all over, and the statistics look fairly regular, with
drivers dominating as they should (since they are most of the tree).
And outside of drivers, we have a fairly usual mix of changes -
architecture fixes, networking, filesystems, and tooling (the latter
being mostly kvm selftests).

Shortlog appended, it's not too long and easy to scan through to get a
flavor for the details if you happen to care.

Please do give it a whirl,

             Linus

Huawei launches OS openEuler, aims to construct 'ecological base of national digital infrastructure'

Chinese tech giant Huawei launched openEuler operating system (OS) on Saturday, another self-developed OS after the HarmonyOS, as it tries to "solve the domestic stranglehold problem of lacking its homegrown OS in basic technology," and build a full-scenario covered ecosystem to prepare for more US bans. The openEuler OS can be widely deployed in various forms of equipment such as servers, cloud computing and edge computing. Its application scenarios cover Information Technology, Communication Technology and Operational Technology to achieve unifying an operating system with multi-device support, according to the company's introduction. In the ICT field, Huawei provides products and solutions such as servers, storage, cloud services, edge computing, base stations, routers, industrial control among others, all of which need to be equipped with an OS. Huawei has therefore been building capabilities to achieve a unified OS architecture, and meet the demands of different application scenarios, the firm said on Saturday. The openEuler program was initially announced back in 2019 as an open source operating system. Today's launch is an updated one. Read more
