Nice heatmap dataviz of Florida COVID-19 cases, over time, by age bracket
Be?v?a?n?d on Twitter: “I love this heatmap?? It represents over 100,000 individual datapoints. These are Florida COVID-19 cases, over time, by age bracket. I published open-source code to make it: https://t.co/8USY29mDDn The recent case surge is driven by 20-24-year-old Floridians. 1/N https://t.co/Pw2p9xTLaq” / Twitter
UASP makes Raspberry Pi 4 disk IO 50% faster
The more recent USB storage protocol — definitely worth using if available. ‘Without UASP, a drive is mounted as a Mass Storage Device using Bulk Only Transport (or BOT), a protocol that was designed for transferring files way back in the USB ‘Full speed’ days, when the fastest speed you could get was a whopping 12 Mbps! With USB 3.0, the BOT protocol cripples throughput. USB 3.0 has 5 Gbps of bandwidth, which is 400x more than USB 1.1. The old BOT protocol would transfer data in large chunks, and each chunk of data had to be delivered in order, without regard for buffering or multiple bits of data being able to transfer in parallel.’ (everyone’s already blogged this, but I’m lodging it here for bookmark purposes ;)
