Worked examples, common mistakes and clear limits for the tools you use.

Read the guide 02JPG, PNG or WebP: which should you choose?
Choose the format for the image and the destination—not just the smallest number.

Use consistent settings, then inspect representative results before publishing.
Read the guide 06MB or MiB? Convert storage without a hidden 4.86% gap
A clear method for choosing decimal and binary units before comparing file sizes.
Read the guide 07Dates, durations and working days answer different questions
Avoid daylight-saving surprises and end-of-month mistakes in everyday date calculations.

A local Naive Bayes classifier can learn your labels. Its usefulness depends on the examples you supply.
