Measure distance to an object by using a laser-based Time-of-Flight sensor. These sensors have a range of up to 2 meters and are pretty accurate. You could use these for all sorts of things like measuring waterlevel in a container (without getting the sensor wet). The sensor works by shining a laser onto an object, and timing how long it takes the light to be reflected back to the sensor. ⚡️Other videos in this series:

APIs are everywhere, they’re in our mobile apps, our desktop apps and even our fridges, and rightly so they often provide a useful service for developers allowing code to be reused across services and devices. But like many aspects of security, this convenience has a trade off when it comes to security. This is where I come in, I am a bug bounty Hunter and some of my favourite things to hack are APIs. In this talk you’ll join me on a beginners trip around the world of API security, showing you the vulnerabilities you can expect to find and how they can be resolved.

Multi-objective optimization (also known as multi-objective programming, vector optimization, multiattribute optimization or Pareto optimization) is an area of multiple criteria decision making that is concerned with mathematical optimization problems involving more than one objective function to be optimized simultaneously. Multi-objective optimization has been applied in many fields of science, including engineering, economics and logistics where optimal decisions need to be taken in the presence of trade-offs between two or more conflicting objectives. Minimizing cost while maximizing comfort while buying a car, and maximizing performance whilst minimizing fuel consumption and emission of pollutants of a vehicle are examples of multi-objective optimization problems involving two and three objectives, respectively. In practical problems, there can be more than three objectives.
