Some of the physics students I tutor recently asked me to explain the Casimir Effect in simple conceptual terms, so here it is...

The Casimir Effect can be noticed if you take two plates separated by a very small distance in a vacuum; there will be a mysterious force that causes the plates to be attracted to each other.

The cause of this effect is analogous and similar to having two plates in a medium, like water; If you apply sound waves to the water with a wavelength greater than the distance of the separation of the plates you will notice the plates will attract. This is because the waves are too big to enter the space between the plates and as such they exert a force on the outside faces of the plates and none on the inside faces, causing them to attract.

However with the Casimir Effect the plates are in a vacuum, and the waves come from quantum fluctuations rather than traditional mechanical waves. As we know from quantum mechanics everything can be represented as waves. We also know that at very small dimensions we witness a "quantum foam", essentially particles and energy constantly flashing in and out of existence. These particles and energy are essentially the source of the waves in a vacuum. If the plates are sufficiently close then only particles and energy of sufficiently small wavelength will occur between the plates, while larger wavelengths would be free to form in the space outside the plates. As such a similar effect as our water example occurs where there are more waves to exert a force on the outside faces of the plates than on the inside faces. As such the two plates are again attracted to each other.

Thanks to multitouch gestures in GTK one can zoom and scroll at the same time.

This is useful right? 🙃️

anyone indenting with spaces is just wrong. there isn't an excuse for it. 🤷‍♀️

my bet: in a few months is going to announce that firefox will use blink as engine ✨

holy fuckin moly are all things XDG broken overengineered shit.

fuck design:

::-webkit-scrollbar {
width: auto !important;
height: auto !important;
max-width: auto !important;
max-height: auto !important;
min-width: auto !important;
min-height: auto !important;
}

::-webkit-scrollbar-track {
background-color: lightgrey !important;
}

::-webkit-scrollbar-thumb {
background-color: darkgrey !important;
border: 1px darkgrey solid !important;
border-radius: 3px !important;
}

::-webkit-scrollbar-thumb:hover {
background: darkgrey !important;
border: 1px darkgrey solid !important;
}
::-webkit-scrollbar-thumb:active {
background: lightgrey !important;
}
::-webkit-scrollbar-corner {
background: lightgrey !important;
}

ah, due to the magick of bootstrap it's a white box everywhere it is used.

🔥

works not on github, where somehow changing the width of the scrollbar sets it to be a completely white box. fucking 💯

fixed it with github.com/openstyles/stylus and

::-webkit-scrollbar {
width: auto !important;
height: auto !important;
max-width: auto !important;
max-height: auto !important;
min-width: auto !important;
min-height: auto !important;
}

is there any fucking way of getting sane scrollbars, as in "wider than 1px", on every page?

It's kind of crazy how different "ideas" currently are floating around in the public space: that covid is a hoax, gates wants to nanochip us, russia haxx0red the us because of the vaccination (which is supposedly just nanochips for a fake illness), etc. i have the feeling that if one conspiracy is really true, it's that the population is being trained in accepting doublethink. it feels like something out of a psyops manual.

i kind of like how is being finally criticized. i never liked the ego of moxie and his opinions that
- federation is dead
- disallowing 3rd party clients is good
- that the choice of telephone numbers as identifier is ok and doesn't make the whole security a LARPing exercise

so, it's a bit weird that the current panic is over a recovery feature which is secure if you use a good passphrase 🤷‍♀️
