Source: Why I recommended ECS instead of Kubernetes to my latest customer

Summary
An AI startup approached the author to help optimize their AWS cloud setup. After going through the latest AWS bill, the author proposed various ways to reduce costs such as changing EBS volumes to GP3, converting to minimal provisioned IOPS, and removing On-Demand instances with low CPU utilization.

Facts

💰 More than half of the customer’s spend is on EC2, along with significant spend on EBS volumes and RDS databases.

🐳 The application is packaged in Docker containers, but having the source code and secrets required to build the images on the running instances doesn’t follow security best practices.

🛑 Turning off instances when no longer needed results in EBS volumes generating costs over time, even though the instance doesn’t generate EC2 instance costs.

Source: The Oldest Maps in the World

Summary
The world’s oldest map is believed to be scratched on the surface of a mammoth tusk found in Mezhirich, Ukraine around 15,000 years ago. The first map features various straight and zigzag lines to represent a topographical feature, a river, and houses or huts. Other ancient maps include a painted map on the wall of a house in Çatalhöyük, Turkey, and an inscribed drawing on a flat rock in the Italian Alps called the Bedolina map.

Fact

🗺️ The oldest recognizable map in the world comes from Ukraine and is dated around 15,000 years ago, scratched on the surface of a mammoth tusk found in Mezhirich.

🗺️ The map portrays a river, topographical feature, and houses or huts depicted by various straight and zigzag lines.

🗺️ The first bird’s-eye view map was painted on a wall in Çatalhöyük, Turkey, portraying rows of houses and a mountain overlooking them, dating around 6200 BC.

🗺️ The Bedolina map, carved on a flat rock in the Italian Alps about 1000 BC, features images of houses, roads, fields, topographical features, armed figures, and animals.

Source: Intravenous Caffeine

Summary
A study conducted by Johns Hopkins University showed a positive correlation between higher doses of IV caffeine and positive effects and euphoria. People usually drink, smoke, snort, or inject their drugs, but IV caffeine has not been a common method of consumption until now.

Fact

💉 IV caffeine has been shown to cause positive effects and euphoria in higher doses.

☕ Caffeine is usually consumed orally due to its fast absorption rate by the gut.

💉 Injecting caffeine comes with the usual risks of needles and infections, and its prolonged effect may require “bathroom breaks” at work.
