A cryptarithmetic puzzle

A puzzle where a mathematical equation is written using letters instead of numbers. Each letter represents a digit from 0 to 9, and no two letters can represent the same digit.

CSS Graph Paper Background

Nice and dark graph for printing graph paper. May need to adjust the 4th parameter of the rgba function to make the lines lighter.

Visualize SQL XML Execution Plan using HTML

I’ve always used the Microsoft SQL Management Studio Execution plan feature to visualize the query plan. However today I was experimenting with the SQL XML showplan statement to see if I could learn anything more about execution plans by looking more closely at the code. As soon as I saw the XML it occurred to me that I could use XSLT to convert the output to HTML similar to the way that the SQL Management studio did it. I was curious to try, but before I writing my own, I checked to see if anyone else did it already and found this on github:

So, to demonstrate I created a simple SQL using temp tables so that I could perform some very basic tests.

Insert some sample data

Turn on the SHOWPLAN_XML in SQL and run query to produce the XML.

Then copy and paste the output XML data into a file and upload to the demo page that uses Justins HTML query plan visualizer library.

What is Twitter shadow ban?

It is the practice of making tweets invisible to the general public in an attempt to censor a particular user. That is the truth. A more politically correct answer is that it is the technique of blocking a user that so that they don’t know that they are being blocked. It is pure deception.

Originally, the concept was intended to reduce spam or undesirable posts from a user that was considered a problem. However, there is a potential that this practice can be abused and used for nefarious purposes. Who judges whether a user is a problem or not and what motives are behind that decision?

I really became interested in this because after the topic came up on twitter. A well known cartoonist named Scott Adams wrote this blog post about shadow banning.
