How much do electric car batteries degrade?

news.ycombinator.com Hannah Ritchie 2025-11-17 09:53:20

It’s always the battery in my mobile phone that gives up on me first. After just a few years, it can barely make it through the day without getting another charge. Most electric cars have the same types of batteries — usually lithium-ion — so the assumption is that they degrade just as quickly. This is a fairly common fear for people considering a new EV: “Won’t the battery need to be replaced after a few years?”. And I think it’s even more prominent in the second-hand market: “Oh, I’d never bu

Rumored F1 movie digital release date points to imminent launch ahead of Apple TV+ debut

9to5mac.com Zac Hall 2025-11-17 15:42:03

A new rumor claims Apple’s F1 movie will be available to own digitally on Friday. However, there are two reasons to be skeptical. The source of the rumor is the aptly named website When To Stream. It claims that F1 will come to PVOD, or premium video on demand, starting this Friday. Forbes notes that the website is “typically accurate for its PVOD reports,” but neither Apple nor Warner Bros. has announced a date.

How to ingest 1B rows/s in ClickHouse

After seeing the engineers at Tesla talk about 1B row/s ClickHouse ingestion, I wanted to see if I could do it myself. A few weeks ago, I saw a talk from Tesla claiming they were ingesting 1B rows per second using ClickHouse. I'm a petrolhead but I don't have any reason to think they are lying :).

As supply chains generate ever-larger datasets and demand faster decisions, traditional central processing unit (CPU)-based systems are approaching their limits. To meet real-time requirements at scale, developers turn to accelerated computing powered by graphics processing units (GPUs). These massive parallel processors reshape how data is accessed, analyzed, and operationalized across the enterprise supply chain.
