silverpill@mitra.social helge@mymath.rocks I'm thinking that Mastodon is likely open to changing things.

@max non volevo un gatto per volere un gatto in generale.
Andando al gattile mi ero affezionata ad una gattina di un anno.
Mi stavo informando sulla possibilità di adozione.
Mi hanno stroncato sul nascere.
Tra le altre cose anche che le finestre di casa non sono protette da zanzariere.

No ma sono delle pazze (uso il femminile perché tutte le persone che ho conosciuto io affette da questa patologia erano donne), lascia perdere il gattile.
A una mia amica non hanno dato il gatto perché ha una casa su due piani, pianoterra e primo piano, e le finestre del primo piano NON ERANO PROTETTE!
Avrebbe dovuto installare qualcosa, non so neanche cosa, per evitare che il gatto si buttasse di sotto... Ha preso due gatte da una signora la cui gatta aveva partorito e quelle due fanno una vita che vorrei essere al loro posto.
Spargi la voce, ogni tanto qualcuno ha dei gattini da dare via.

Meter Mods Make Radioactive Prospecting More Enjoyable
While we often get a detailed backstory of the projects we cover here at Hackaday, sometimes the genesis of a build is a bit of a mystery. Take [maurycyz]’s radiation survey meter modifications, for instance; we’re not sure why such a thing is needed, but we’re pretty glad we stumbled across it.
To be fair, [maurycyz] does give us a hint of what’s going on here by choosing the classic Ludlum Model 3 to modify. Built like a battleship, these meters would be great for field prospecting except that the standard G-M tube isn’t sensitive to gamma rays, the only kind of radiation likely not to be attenuated by soil. A better choice is a scintillation tube, but those greatly increase the background readings, making it hard to tease a signal from the noise.
To get around this problem and make rockhounding a little more enjoyable, [maurycyz] added a little digital magic to the mostly analog Ludlum. An AVR128 microcontroller taps into the stream of events the meter measures via the scintillation tube, and a little code subtracts the background radiation from the current count rate, translating the difference into an audible tone. This keeps [maurycyz]’s eyes on the rocks rather than on the meter needle, and makes it easier to find weakly radioactive or deeply buried specimens.
If you’re not ready to make the leap to a commercial survey meter, or if you just want to roll your own, we’ve got plenty of examples to choose from, from minimalist to cyberpunkish.
