Not a question. Locking.

It's not FOSS, but it uses markdown which is open, so even if Obsidian went down the path of enshitification, you could still (in theory) move your content over to an alternative. I know, I know, plugins, non-standard etc. etc..

I get your point, but when a part broke on my Prusa, I jury rigged it, downloaded and printed a replacement part and swapped out the broken part for the (improved) new one. With many other brands it would have been an expensive purchase and I would have had to wait for parts to arrive.

Support question. Locking.

In archery, arrows have three feathers (in a Y shape) rather than four (+) so that it can slide past the bow without damaging the feathers or the bow. This means that the arrow can be nocked either the right way (with the leg of the Y away from the bow) or the wrong way (with the leg of the Y towards the bow).

In medieval Europe, the arrow would be nocked with the bow held horizontally. To make it easier for archers to quickly and easily nock their arrows, the feather to go away from the bow (pointing upwards) was a different color, and came from a cock (rooster). So when drilling new archers, if they nocked the arrow the wrong way, the instructor would shout "Cock Up!".

This came to mean a mistake.

Floors in the Middle Ages were dirt covered with straw for insulation and other reasons.

Threshold = thresh (straw) + hold (a piece of wood across the front doorway to stop the thresh from spilling out)

This is also why the symbol for a British pound Sterling is a stylised "L".

Edit: the currency was at one time backed by silver, so 1 GBP used to be = 1 lbs silver.

Sigh, Rule 5 definitely needs clarifying....

[–] Bluetreefrog@lemmy.world 0 points 2 weeks ago

Rule 5. Locking.

[–] Bluetreefrog@lemmy.world 2 points 2 weeks ago

Locking. Too many people breaking rule 1.

Keep it nice people!

This is either a flat out lie or grossly ignorant.

The Soviet Union was responsible for multiple geocides.

Don't spread misinformation.

 

Rule 6 states "No US politics", but methinks this is kinda grey on that one.

Upvote this post if you think we should allow posts in AskLemmy.world on the current situation in Iran (provided they don't clearly break the existing rules), and down vote if you think they should be banned.

 

The impact that wiped out the dinosaurs also wiped out all songbirds, except for in (ark) Australia. Australian songbirds then spread out to rest of the planet.

The closest living descendents (aka basal lineages) are the Lyrebird and the Rufus scrub bird. The lyrebird's song is a mixture of its own song and other birds songs. They have been also been known to mimic chainsaws, car alarms, camera shutters, and human speech.

 

For those who aren't familiar with the term, it means believing something that probably shouldn't be believed, or being influenced to believe something that's not necessarily in your best interests.

 

Abstract

Many “smart” and “fitness” watch bands are advertised to contain fluoroelastomers, a type of synthetic rubber designed to be resilient against skin oils and sweat. Fluoroelastomers, which are considered a polymeric form of per- and polyfluoroalkyl substances (PFAS), have historically involved the use of shorter-chain PFAS as surfactants in the polymerization process. In this study, 22 watch bands were analyzed across numerous brands and price points for the presence of PFAS. Products were first screened for total fluorine using particle-induced gamma-ray emission spectroscopy on the surface of these bands, and 15 of the 22 watch bands contained total F concentrations >1% fluorine, suggesting the widespread use of fluoroelastomers in this product category. Watch bands then underwent solvent extraction and targeted LC-MS/MS analysis for 20 PFAS. Perfluorohexanoic acid (PFHxA) was the most frequently detected compound with concentrations from <LoD to 16662 ng/g. A subset of six watch bands also underwent direct total oxidative precursor (dTOP) assay to determine the presence of PFAS precursors. The very high concentrations of PFHxA readily extractable from the surfaces of fluoroelastomer watch bands, together with the current limited knowledge on the dermal absorption of PFHxA, demonstrate the need for more comprehensive exposure studies of PFHxA.

 

Hi Everyone,

We are looking for another person to help out moderating AskLemmy. Home instance does not matter, and Accounts will need to have a history of positive contribution to Lemmy.

DM or reach out via Matrix if interested.

 

I'm getting a bit sick of large corporations a) demanding excess data as a condition of doing business with me, b) allowing it to be stolen, and c) giving zero fucks about it.

What are some things that us netizens can do to make our displeasure known.

Extra points for funny ideas.
