I Made a Floppy Disk from Scratch Polymatt decided he was going to make a 3.5” floppy disk from scratch — and actually did. I’m not sure how many of you have actually cracked one of these things open and taken a look inside, but it’s actually a little bit more complex than I expected. Recreating a shell isn’t going to be the tough part. It’s actually this: recreating the media itself with some PET film and a bunch of chemicals.

Here’s Why Crypto Set the Market on Fire Yesterday

gizmodo.com Riley Gutiérrez Mcdermid 2025-11-08 15:56:24

Cryptocurrency markets skyrocketed into new territory Friday after Federal Reserve Chair Jerome Powell signaled that interest rate reductions could be imminent, pushing the Dow to its first 800-point plus gain this year. That ended the Dow’s longest streak without a new high since Dec. 4, 2024, according to Dow Jones Market Data, and signaled a major surge of optimism at the prospect of some economic policy relief. Cryptos were major stars of that rally. Ethereum (ETH) climbed over 15% to reac

On August 22, 2020, Warner Bros. held its first-ever DC FanDome, a weekend-long virtual event meant to make up for that year’s San Diego Comic-Con, which was canceled due to the pandemic.

All online brands offer a free trial, free shipping and a warranty, but some brands are more generous with their policies than others.

Top Secret: Automatically filter sensitive information

What happens when you’re dealing with free text? Filtering the entire string may not be an option if an external API needs to process the value.
