LLMs tell bad jokes because they avoid surprises

LLMs generate slop because they avoid surprises by design LLMs suck at comedy, art, journalism, research, and science for the same fundamental reason Dan Fabulich 5 min read · 3 days ago 3 days ago -- Listen Share Have you ever asked an LLM to tell you a joke? They’re rarely funny at all; they never make you actually laugh. There’s a deep reason for this, and I think it has serious implications for the limitations of LLMs, not just in comedy, but in art, journalism, research, and science. Jo

Electricity prices are climbing more than twice as fast as inflation

Electricity prices are climbing more than twice as fast as inflation toggle caption Ken Thomas Ken Thomas woke up this past Wednesday to find the power had gone out at his house in Boca Raton. A text message from his utility said a piece of equipment had failed at 2 a.m. By the time a repair crew showed up eight hours later, the hot, sticky Florida summer was already taking a toll. "You just don't realize how important your power is until you don't have it," says Thomas, a retired air traffic

Lessons learned from building a sync-engine and reactivity system with SQLite

Derivatives, Gradients, Jacobians and Hessians

This article explains how these four things fit together and shows some examples of what they are used for. Derivatives Derivatives are the most fundamental concept in calculus. If you have a function, a derivative tells you how much that function changes at each point. If we start with the function , we can calculate the derivative as . Here are those two functions graphed.

Disney’s Got a Cool ‘Andor’ Zine for Emmy Season

What Is the Electric Constant and Why Should You Care?

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational constant, and Planck’s constant, and they’re “fundamental” in the sense that we can't derive them theoretically, we can only measure them. We use these in solving physics problems all the time, so it’s easy to take them for granted. But why are there such numbers in nature, and why do they just happen to

Is now a good time to buy an Apple Watch?

This excellent Samsung Good Lock feature should come to all Android phones

Seagate spins up a raid on a counterfeit hard drive workshop

How randomness improves algorithms (2023)

Since the very first days of computer science — a field known for its methodical approach to problem-solving — randomness has played an important role. The first program to run on the world’s first general-purpose electronic computer used randomness to simulate nuclear processes. Similar approaches have since been used in astrophysics, climate science and economics. In all these cases, plugging in random numbers at certain steps in the algorithm helps researchers account for uncertainty about th
