I was there during the crypto-bubble, the housing market bubble, but I don't have any memory of the internet/dotcom bubble, and I was not alive during the rail-road bubble.

However, I want to know what the thoughts of the people were during that time. During AI, that fact that it's a bubble is more apparent but during the housing and dotcom, I feel like it was more subtle (or I am too naive).

Does anyone have any personal experience of what it was like at that time? Were people as skeptical as they are today? What were they right/wrong about? Were the attitudes different? What changed after the crash?

China's booming sodium-ion battery industry is facing an unexpected challenge as coconut shell-based hard carbon, a key anode material, becomes increasingly scarce and expensive. To overcome the shortage, researchers and manufacturers are turning to coal-derived hard carbon, aiming to lower costs, secure supply chains, and accelerate large-scale sodium battery production.

He's so sweet tho. It's good there's still daylight 😊

Infineon Technologies has opened its Smart Power Fab in Dresden, Germany, months ahead of schedule, bringing the world’s largest manufacturing facility for intelligent power semiconductors and analog/mixed-signal technologies into operation.

The facility represents a €5 billion (about $5.7 billion) investment, the largest in the company’s history. It creates 1,000 direct jobs and doubles Infineon’s manufacturing capacity in Dresden.

The factory will produce chips that improve how electricity is converted and managed. Those devices will support AI data centers. They will also help power electricity grids and software-defined vehicles.

Hi folks. I obtained a pre-owned Anycubic Vyper. Alas, every print features defects in the surface as shown in the picture. It occurs in any type of material. Does anybody know the source of this type of defects?
