Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

TinyML: Ultra-low power Machine Learning
There are a range of ML acceleration possible on existing chips. The basic 4-wide 8 bit integer SIMD extensions in NEON is available on basically all ARM Cortex M4F chips, which is already available 8+ years. It gives 4-5x speedup for neural networks.
The more recent ESP32-S3 has operations with up to 10x speedup, see https://github.com/espressif/esp-nn
Then there are RISCV chips with neural network co processors like Kendryte K210.
ARM has also defined a new set of extensions for NN acceleration, and reference designs for cores being ARM Cortex M85. Chips are becoming available this year.

Ask HN: What Are You Working on This Year?
The ESP32-S3 introduces vector instructions which are supported by TFLite already. See here - https://github.com/espressif/esp-nn#performance
S3 also supports Octal PSRAM vs the single lane SPI PSRAM found on the older ESP32-CAM style boards, should be 8x the bandwidth with all else equal. So far I've only seen the octal PSRAM's available on WROOM modules and it looks likes there only support for Espressif branded Octal PSRAM chips at this point.

Ask HN: Those making $0/month or less on side projects – Show and tell
RoQR: https://roqr.app/
It's a privacy-focused dynamic QR code application. Just got my first paying customer this past week, which I'm pretty stoked about!
The costs of running it are very low (~$15 / month), and it's not something I'm planning on ever turning into my main gig, but the fact that someone is willing to pay for an app I built on my own feels really fun
