Oh, you're not on FB I take it? Been mentioned a lot.

Don’t even need FB to be aware of it, as it’s been all over the social media interwebs too.


Anyways, to those with SO’s here’s a little something to save $ and gain points for the upcoming Vday -



You’re welcome :)

Scientist Shuji Nakamura who discovered the method for viable scalable blue/white LED had been discouraged, dismissed by peers almost anywhere he worked and regularly told to give up by his boss - then in true late-stage capitalist fashion has never been compensated for the labour and focused determination which is now earning the corporation (who insisted he give up and no longer works for) millions/billions yearly in growing profits. They even tried suing him after he moved abroad to continue work elsewhere on his discoveries, cause that's the core foundation of capitalism baybae: merit and hard work dont mean shit until a corporation (specifically the wealthy owners of corporation) can rob it from you, exploit it and claim it as their own, all while legally bullying you with the vast new cash you made for them.

Ok, so everyone knows that Kennedy was killed in late November 1963, and that lots of people think the CIA/whomever was involved.

And I knew that the CIA had supported a coup that ousted and killed the leader of Vietnam in the 60s, but I didn't know it was in the beginning on November 1963.

Now, not saying that the latter proves the former, but I wonder if the CIA's involvement in the latter just weeks before the former led to increased conspiracy theories.

Too bad we didn’t get the robins yet. Those fuckers were already starting on my front porch windows and shitting on my railing this AM, in bloody Michigan.

Domestos, the common cleaning product, is not suitable for sterilising water, because, like many bleach products, it also includes other stuff.

Not that I expect to need to sterilise my own water any time soon, and I do have the ability to make fire, but, you know, random bit of trivia.

In the atmospheric (mostly Scottish) film 'Under the Skin' - the Scarlett Johansson victim with the touching scene involving visible deformities I'd assumed at first was make-up/prosthetics, but is legitimately the actor and activist Adam Pearson.





And another A24 film on its way too??
Pearson's next film role will be in A24's A Different Man, which is set to have its world premiere at the Sundance Film Festival in 2024 in the Premieres section. He will star alongside Sebastian Stan and Renate Reinsve.
Ok maybe 'Under the Skin' wasn't A24, but it might as fckin well be, all the traits are there!

Supernovae so quaint, adorable even. couldn't shake hair off a dead bear's arsehole nowadays.

Its reign is over. supernova dead. long live the

KILONOVA.


if no prog-metal/psy-trance type band's nabbed it yet for name use, the window is surely closing as we speak, as time windows always do, for us to be the first. and by us I mean anyone but me.

In the US, just before the 20th century, there was a brief fad for tombstones mad from zinc, mostly standardised by one company. They have removable plaques so you can change the names around if someone else died.

Use of the word Chagrin has seen a notable upswing in use over the last 20 years. See Genz aint all bad.

Looking at a propaganda film about Australian planes in WW2 (while Australia did make it's own planes, they weren't great, and were intended as trainers or ground attack craft, not dogfighting zeroes). One thing they did to get a tight fir between parts was to stick the outer part in boiling oil, and the inner part in dry ice. Put the inner in the outer, and when they return to room temperature, the expansion and contraction means they'll be stuck together.

Weird. We’ve sent stuff to Pluto and beyond but waited over half a century to send another thing to the moon. I guess NASA got bored of something.
To be fair, space exploration is just expensive and risky enough that going to the same planet or moon every time you can, without the very real expectation of learning something new or valuable, doesn't make much fiduciary sense. I mean if 8 new restaurants were available in your city, could you reasonably justify spending exorbitant amounts going to the same restaurant on your block then saying you've substantially expanded the culinary knowledge of your wider area? Could you imagine if we sent astronauts to our moon every time we had the budget for it, and when the inexorable accident happens, and we lose a crew of people, only having another handful of moon rocks to show for it?

Don't get me wrong, in terms of space exploration, I'm personally of the mindset that we've got enough shit to fix down here on Earth, that the curiosities of distant heavenly bodies should be relegated to a hobby and not international efforts and resources. We're spending BILLIONS to peek at planets we can't reasonable reach in any substantial way, yet, I can walk out my front door and see dozens of people for whom a $500 medical deductible could be financially crippling. Me thinks our priorities might be a bit upside-down; "why are we just now returning to the moon?" I'd ask why did we ever bother in the first place let alone going again no matter how many years later. We're surrounded by war, poverty, famine, insufficient healthcare, etc.; who gives a shit about some billionaires who'd rather spend their wealth staring into space, jerking each other off while the world around them burns?

(Sorry, got a bit rant-y there...)

Well yes, there’s certainly *all of that* and I sure as hell won’t disagree. But speaking strictly of space exploration, it’s kinda funny how the astronomical costs of it didn’t stop NASA from going to the same place what, half a dozen times in a very short span of time, back when technology was nowhere near what it has become since. Then we send stuff to Mars, and a few other places that very likely have any benefit to the human condition on earth. The logic to at all is very odd to me, but of course what else can be expected when *see your reply*.
