Does anyone have any reccs for print journals or magazines for developers/computer nerds that require a bit less brain than, say, hacker zines? For when you want to touch grass but not too much

This is incredible: CCC #39C3 (hacker conference in Germany) is doing CO2 room monitoring this year just like @kawaiicon.bsky.social so attendees can assess risk!

Phone cameras are wild now. If I can't read a distant sign I can take a handheld shakycam photo at 8x zoom and there it is.

Bluesky and the microblogging part of the fediverse are an interesting middle ground where some people (like me) carefully manage whom they follow, and others follow like mad and don't worry about too much what they do or don't see.

I don't always build custom rust toolchains, but when I do, it's because Apple hasn't finished upstreaming their stuff to LLVM

Say what you will about AI coding, if you make an LLM send me personalised emails and act all proud of yourself I’ll be about as grumpy as Rob. Nonconsensual AI communication is a modern scourge.

I learnt recently that the PDS oauth flow doesn’t yet support scoping/restricting record access between different appviews (github.com/bluesky-soci...) so I guess be careful about throwing your Bluesky login into sketchy or experimental apps if you care about it a lot.

Note: a more complete proposal was published in July 2025: https://github.com/bluesky-social/proposals/tree/main/0011-auth-scopes We’re continuing work on rolling OAuth out to the atproto network. ...

Dubious product as it was, Microsoft Recall never had any feature for sending screenshots to a cloud, let alone for AI training. Surprisingly, there are still people who claim otherwise and expect us to take their commentary seriously.

I realise user agent strings are more lies than truth but it's still funny to me that Safari on Apple Silicon with Tahoe still reports itself as "Macintosh; Intel Mac OS X 10_15_7"

Dear lazyweb, does anyone know of a switchable smart power outlet that is controllable either by straight BLE or LAN API without complex auth or cloud stuff? Trying to avoid going to a full-on PDU as it’s a small job.
