FOR THE LOVE OF ALL THAT IS HOLY, DON'T TRY RIDING ONE OF THOSE LIME PIECES OF SHIT WHEN YOU ARE TOO DRUNK TO STAND
<mofh>
ESPECIALLY DO NOT TRY DOING THIS ON THE FUCKING *SIDEWALK*
<SnoopJeDi>
a public menace
<mofh>
I DO NOT CARE IF YOU WANT TO DISCOVER FIRSTHAND ALL THE FUN DYNAMICAL INSTABILITIES THOSE THINGS HAVE, BUT I'D RATHER NOT BE PRIVY FIRSTHAND TO YOUR DISCOVERY PROCESS WHEN IT HAPPENS.
<mlbaker>
"lime pieces of shit"?
<mofh>
No love, and a prolly badly pronounced "va te faire enculer" yelled at your general direction, mofh.
<mofh>
No, the Waterloo Scooter BS things are literally the same everywhere.
<mofh>
Like that is their international product.
<mlbaker>
oh wait, so it *is* the same?
<mlbaker>
LOOOOL
<mofh>
YES.
<mofh>
average lifetime of one of those in Paris is twenty eight days
<mofh>
they're a decent source of BDLC motors and a shitty source of 18650s, in a pinch at least.
<mlbaker>
wow i didn't know this was an actual thing
<SnoopJeDi>
It's like dockless bikes but way worse
<mlbaker>
i thought it was like some waterloo bro who went to silicon valley
<mlbaker>
and started this company
<mlbaker>
and decided to run the first pilot at UW
<mofh>
mlbaker: no it's international unfortunately
<mofh>
mlbaker: like this is why my reaction to seeing one of those in UW was "OH GODS CAN I NOT ESCAPE THIS SHIT" since I first got familiarized to them in Paris
<mofh>
where they are a fucking menace
<mlbaker>
haahahah
<SnoopJeDi>
there's a guy in my neighborhood who is a quadriplegic and it brings my piss to a boil whenever I see one of the local dockless bikes in the middle of a sidewalk thinking of him
<SnoopJeDi>
Wish you could report bikes left in stupid positions etc. and boot the dickheads who abuse the share
<mofh>
jfc that's even worse than all of my complaints, honestly.
<mofh>
and mine mostly center around clueless dipshits, often tourists, going way too fast on those things, often on the sidewalk, and barely missing or outright hitting other people.
<SnoopJeDi>
In defense of the public nuisance business, there aren't _any_ sidewalks where I most often see him walking his guide dog
<SnoopJeDi>
and where there are sidewalks, they're often blocked by trash bins or brush trimmings or other stupidity
<SnoopJeDi>
you'd think the ADA straight-up doesn't exist based on local governance.
<SnoopJeDi>
I really hope we don't get the scooters
<SnoopJeDi>
mofh, as a palate cleanser, the bikes have been *very* good for the local population who doesn't have cars, and the city has leaned into the fact that people have been using the bikes to get to/from the grocery store
<SnoopJeDi>
Particularly when we had ofo here. When they closed up shop (perhaps this was the plan all along?), the city established a program to give the bikes away.
<mofh>
I mean I contend there *is* a use for ride-share scooters, especially in places where the local transit is shit (hint: Paris is very much not one of those places). But the way Lime manages everything about it is like, the worst possible way to implement it possible.
<SnoopJeDi>
there definitely is, particularly the tourist market they target
<SnoopJeDi>
but our tourists are mostly assholes coming to relive their glory days at college, and the policies are just gross. The companies do not care about the cities they're exploiting.
<mofh>
egg: my favourite fr-CA thing is that "dépanneur" means, well, épicerie.
<SilverFox>
wait up
<SilverFox>
I google epicerie and its grocery stores, but depannuer is corner stores
<SilverFox>
convenience stores
* UmbralRaptop
misread that as Californian French
<mofh>
I mean in fr-FR, dépanneur is repairman service,
<SilverFox>
jesus I would not like to see what californian french is
<SilverFox>
yeah it translates as repair service, or "Troubleshooter"
<SilverFox>
"au Québec, une petite épicerie de proximité ou une supérette." ah
<SilverFox>
how does this even happen, what is the etymology of that

mofh, woke up at 3 last night and couldn't get back to sleep until 6, as I random-walked the web in frustration I came across this, which you will likely enjoy if you've not seen it before: https://imgur.com/gallery/l0q7D

hrm, wouldn't a hyperbolic soufflé be considered bad? since that sort of structure would primarily happen during structural collapse
<UmbralRaptop>
FRLW soufflé with negative curvature
<SnoopJeDi>
Heh, I coincidentally happen to have the wiki page for FLRW open in a tab right now. A college friend emailed me to ask a question about cosmic expansion and it has turned into An Overly Long Reply
<UmbralRaptop>
The sun is rather boring right now =\

The local astronomy on tap group has been running long enough that I don't feel guilty poking my nose in to volunteer for a talk as a non-astronomer
<SnoopJeDi>
and particle pew-pew in space is 1) not something anyone here is working on, so no toe-stepping concerns, 2) close enough to accelerators that I can get away with pretending like I know what I'm on about
<UmbralRaptop>
SnoopJeDi: jets from black holes are basically accelerator physics, right?
<SnoopJeDi>
(it'll probably be solar wind + misc. space weather)
<SnoopJeDi>
UmbralRaptop, yup! Probably one slide's worth in the intro, I think sticking close to home will make it more relatable to a public audience.
<SnoopJeDi>
But our cyclotron is all about those sorts of reactions
<SnoopJeDi>
Just recently attended a friend's defense on α-capture rates in ²²Ne(α,n)²⁵Mg, in fact
<UmbralRaptop>
hrm
<SnoopJeDi>
(although I think that's much more about hydrodynamics)
<SnoopJeDi>
mofh, relatedly, I may sometime in the next month pick your brain for a slide or two on Voyager :)
<SnoopJeDi>
Or possibly DSN, if space weather has a substantial impact there
<mofh>
Not hugely, outside of solar conjunction being a pain to work with.
<SnoopJeDi>
Makes sense, Space Is Big™?
<SnoopJeDi>
(and it's already such a damned pain)
<mofh>
More like the frequencies in question aren't affected badly enough to cause *problems* outside of minor changes in noise PSD.
<mofh>
X-band is very nice overall
<SnoopJeDi>
speaking of X-band
<SnoopJeDi>
I have a placeholder slide for the nuclear electron flux mitigation thing that is all-caps reminders that I decided a long time ago that I shall not have more than one slide about it because nukes are depressing
<UmbralRaptop>
#2 is fine, for #1 I have the eigenvalues, but unsure with eigenfunctions, and am probably missing a bunch for the time evolution
<UmbralRaptop>
B787_300: well, studying for them
<B787_300>
when are you taking them?
<B787_300>
i like "The exact calculation is feasible in an exam, but long and perilous - avoid at all costs."
<B787_300>
also i have no idea how to do any of those questions
<UmbralRaptop>
So, uh, for 2 you can literally grab an equation out of the textbook. I think the perilous part is calculating an inverse hyperbolic sine?
