I live in the #Netherlands and make a living in #tech working for #RedHat. I am passionate about using #foss and #decentralisation to get people back from being puppets to being citizens. Currently the #fediverse is our best shot at this. I am also interested in #Buddhism and regard myself a #dharma student. I love to #ski and #hike and regularly travel to the #Alps. Love to do #stargazing and wonder about the meaning of it all.
@musicmatze @nik That's an incredibly disingenuous way to go about this, and feels like you're actually just clickbaiting people. and for what? Clicks mean nothing here.

I know a lot of folks on this platform don't have TikTok, but this commentary by Antifascist Dad on Ta-Nehisi Coates's interview with Ezra Klein is really worth the watch, particularly the commentary on how white liberals have used the dharma to blunt social change.

Jack Dorsey Launches a WhatsApp Messaging Rival Built On Bluetooth - Slashdot

Jack Dorsey has launched Bitchat, a decentralized, peer-to-peer messaging app that uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. The beta version is live on TestFlight, with a full white paper available on GitHub. CNBC reports: ...

In my keypad scanning firmware, the code looks for buttons at every intersection of an 8x8 grid, for a total of 64 possible locations. Currently, it returns this as a u64, where each bit indicates key up or down at each possible location.

The actual scanning code processes units of 8 bits, for efficiency. So at each step it needs to take 8 bits and shift and combine it into a u64. That happens here:

Today's fun lesson in Rust firmware size optimization: a case where being clever and doing something "more efficient" made things bigger and slower.

Specifically, a bitwise shift that cost 128 bytes, or 2% of the entire flash size.
