The half-life of caffeine can be used to calculate how long coffee will affect you after you drink some. Knowing this can help you adjust your coffee intake in order to improve your sleep schedule, or help you determine how often you should drink caffeine in order to maintain a stable level of caffeine through the day.

The biological half-life of caffeine in typical adults is between 5 to 6 hours. This means if you had 100 grams of caffeine, you would have around 50 grams after 5 hours.

Keep in mind that after the amount becomes very small, it is likely that the body will dispose of it all at once rather than halving the amount forever.

One of the interesting parts of SerenityOS is the YouTube channel of the creator.

Creole (or WikiCreole) is a lightweight markup language that aims to standardize the Wiki syntax commonly used across the different Wiki systems. It is therefore expected that a document written with the Creole syntax should render correctly in most Wiki engines.

The Average Distance Classifier is a simplified version of the Nearest Neighbour classifier. It is really easy to implement compared to other classification algorithms. Because it discards a lot of the data given to it, its accuracy can be worse than other classifiers. The algorithm can be thought of as a nearest-neighbor where each label is a single neighbor.

The project URL entered into BOINC is just a human-readable (X)HTML page. The RPC communication happens on a separate endpoint. This endpoint is located by fetching the project URL and looking for a specific tag.

There are two different ways to find the tag. It is recommended to implement both of them to maximize compatibility.

What are Cryptology, Crpytography, Cryptoanalysis

The short answer:

Cryptology is a science which is interested by secure communication on an insecure communication channel.

Today, all communications passes over unsecured channels like letters, wired and wireless channels which sending data over. So, anyone able to interrupt or listen the message who is in same channel.
