Ubuntu

networkworld.com: PC cases come in many form factors, but they're all basically boxes that lack personality. This doesn't have to be the case (pun intended), as my Carpet Cleaner PC very well proves. Yes, this is a working Ubuntu PC built out of an old Bissell Carpet Machine.

The Most Innovative ~$50 Graphics Card For Linux Users

This ~$50 USD graphics card is open-source friendly, can drive four display outputs simultaneously, passively cooled, and can fit in a PCI Express x1 slot. It's a unique card offering good value especially for those Linux users wanting open-source friendly hardware. Earlier this year ASUS announced the GT710-4H-SL-2GD5. In the months since we didn't hear anything more about it given the pandemic but recently saw it became available via Internet retailers and picked one up for testing. Read more

Plasma on the Edge

You probably have heard the news by now that Microsoft have released the Linux version of their new Chromium-based Edge web browser. Of course I’ve been waiting for this day ever since they announced the switcheroo to Chromium in order to bring Plasma Browser Integration to Edge users. It took Microsoft almost two decades to offer another web browser to a Unixoid desktop and this time around it’s based on KDE’s legacy – what a time to be alive! You can already use Plasma Browser Integration just fine with Edge by installing it from the Chrome web store. Until Plasma 5.21 is out, however, it will only see it as yet another Chromium, meaning that KRunner, media controls, and so on might not map to the correct browser window or show only a generic icon.

  • Python Morsels: The 2 Types of "Change" in Python

    The word "change" is ambiguous in Python: we have two distinct types of "change" in Python. We can "change" a variable by changing which object that variable is pointing to. We do that through an assignment statement. We can also "change" an actual object through a mutation. Let's take a look at both types of change.

  • Python: Slice Notation on String

    The term slicing in programming usually refers to obtaining a substring, sub-tuple, or sublist from a string, tuple, or list respectively. Python offers an array of straightforward ways to slice not only these three but any iterable. An iterable is, as the name suggests, any object that can be iterated over. In this article, we'll go over everything you need to know about Slicing Strings in Python.

  • R vs Python for Data Analysis — An Objective Comparison

    There are dozens articles out there that compare R vs. Python from a subjective, opinion-based perspective. Both Python and R are great options for data analysis, or any work in the data science field. But if your goal is to figure out which language is right for you, reading the opinion of someone else may not be helpful. One person's "easy" is another person's "hard," and vice versa. In this article, we're going to do something different. We'll take an objective look at how both languages handle everyday data science tasks so that you can look at them side-by-side, and see which one looks better for you. Keep in mind, you don't need to actually understand all of this code to make a judgment here! We'll give you R vs Python code snippets for each task — simply scan through the code and consider which one seems more "readable" to you. Read the explanations, and see if one language holds more appeal than the other.
