Lumafield Peers into the 18650 Battery
[Alex Hao] and [Andreas Bastian] of Lumafield recently visited with [Adam Savage] to share their battery quality report, which documents their findings after performing X-ray computed tomography scans on over 1,000 18650 lithium-ion batteries.
The short version — don’t buy cheap cells! The cheaper brands were found to have higher levels of manufacturing defects which can lead them to being unsafe. All the nitty-gritty details are available in the report, which can be downloaded for free from Lumafield, as well as the Tested video they did with [Adam] below.
Actually we’ve been talking here at Hackaday over at our virtual water-cooler (okay, okay, our Discord server) about how to store lithium-ion batteries and we learned about this cool bit of kit: the BAT-SAFE. Maybe check that out if you’re stickler for safety like us! (Thanks Maya Posch!)
We have of course heard from [Adam Savage] before, check out [Adam Savage] Giving A Speech About The Maker Movement and [Adam Savage]’s First Order Of Retrievability Tool Boxes.

I watched some of apple's #Foundation but I gave up for now.
It bothers me that everything revolves around Chosen Ones when the books were mostly the opposite (up to a point).
I get why they did that but meh.
Also, those chosen ones plot lines are.. boring? I just don't care.
The original idea of the genetic emperor could be interesting but doesn't really mix in with the rest, and suffers from "one episode character" disease, so I don't care about them either.
5/10.

Croazia, Pag e Vyr: nuove speranze per la mia nuova casa in Europa.
Tante persone che soffrono di artrite, avevo letto, si erano trasferite in Croazia. Perché?
Dovevo scoprirlo. Dovevo sapere se la Croazia avrebbe potuto essere la mia nuova casa, dove stare finalmente bene.
🔃Condivisione gradita. 👇🏻

Dear Fedi friends,
Good morning from #FOSDEM!
Yesterday was pure magic: I loved every single presentation in the Social Web devroom, with devs and Fediverse champions sharing their inspiring work.
I didn’t post anything because I was so absorbed in all the talks (plus @liaizon and @Sascha did a fantastic job chronicling the event).
I can’t stop thinking about one of @benpate’s closing slides:
“Every single thing you do to improve the Fediverse is a win for humanity”
YES! 🙌

@mariosiniscalchi ho parlato di presenza, e partecipazione, i giudizi li lascio ad altri, cui prodest e stretta repressiva compresa

@VileLasagna That's the rub, right? Not enough people _need_ that feature.

@egoldblatt @pafurijaz it is "free as freedom" not free as free beer. You can have foss project that you need to pay for.
" Free software means that the users have the freedom to run, edit, contribute to, and share the software. Thus, free software is a matter of liberty, not price "
From : https://www.fsf.org/
So a FOSS software can still be a paid one

anyway to dial down the sun?
If heat is the problem, try Tasmania. It's a bit cooler than the rest of the country. Unfortunately, sunburn remains a strong possibility in summer.
