Today we will be reproducing @arcange's Daily Hit Parades. There won't be any visualization-related code, but we will learn about recursive common table expressions along the way. Preparation Before we

Taking derivatives from both sides of a valid equation we obtain Dividing both sides by x, we must conclude that 2 = 1. For other sophisms check out my other posts.

No matter how many specialized accounting tools there may exist nowadays, Microsoft Excel is still one of the best choices for keeping track of personal finances. It is easy to start with, incredibly flexible,

Consider an arbitrary triangle ABC. Let G be the midpoint of AB and let D be the intersection of the midpoint perpendicular of AB with the bisector of ∠C. Drop perpendiculars DE and DF to the sides AC

Our next order of business: the distribution of reputation scores among active Steemit users. Before we start, we prepare the workspace as usual (see the previous posts in the series for additional context:

Let us reproduce the next chart in the @arcange's report - the distribution of post counts by category. Before we start, we prepare the workspace as usual (see the previous posts in the series for additional

Bart's Cookie Store is selling two types of cookies - vanilla and chocolate. Vanilla cookies sell at $1 per three pieces, while chocolate ones sell at $1 per two. At the beginning of the day Bart had 30

Consider the following statement: This whole statement is true if and only if the Earth is flat Let us denote the whole statement by A. Note that we can then rewrite it a bit more formally as the following

In the previous posts of this series (1, 2) we counted users. Next stop - counting posts, comments and upvotes. Preparation Before we start, we prepare the workspace as usual (see the first post for

Let us continue reproducing @arcange's statistical reports in Python. Recall that in the previous post we counted newly registered and total users on the site. The next step is counting active users on

The Liar's Paradox is perhaps the shortest sophism there is. In its most common form it fits in just four words: This sentence is false. Think about it: if the sentence is indeed false, then we should

Every single day the user @arcange posts three statistical reports replicated in three different languages (actually, there's a fourth report on the cryptocurrency, which he somewhy only posts at the Russian
