Since the stars are near 1 solar mass and each has <10d orbital period, I think pairs should be nearer than Mercury to our sun which has 88d period.
Then the paper gives the separations of the systems as 18AU for the inner quadruple and 250AU for the whole system. That would put the inner system within the orbit of Uranus and the whole system larger than our solar system which has Kuiper belt at 50AU.
I think the an easy way to think about it is by thinking about function types, instead of collection types.
Func Arg Val represents a function type from Args to Vals
consider foo(func : Func a b)
The argument to the function foo must be assignable to (a subtype of) Func a b
What are those subtypes? We can find out by considering expressions involving the argument
bidentifer = func(avalue)
so func must be an object whose type is compatible with assignments from the avalue, so its argument type must be a supertype of a
while the assignment to bidentifier implies the return value must be assignable to the return type so it must be a subtype
therefore the subtypes of Func a b are the set of types Func (super a) (sub b)
this is the origin of the phrase be generous in what you accept and specific about what you return
thinking about whether bikes are vehicles and such doesn't really clarify anything. you have to actually think about the expressions you are trying to construct
Moving down the Func type hierarchy moves you up the Argument type hierarchy (contra) but moves you down the Return type hierarchy (co)
I only zone out in meetings with no focus. Provide an agenda which describes what you want to talk about. This helps me identify my value and not begin to immediately wonder how long this aimless meeting will last. Describe the problem this meeting wants to solve and why you can't solve it by yourself. People schedule meetings and expect attendees to do the work on making the meeting successful.
It's not my responsibility not to be bored, it's the organizers responsibility to be engaging.
I thought the name looked familiar. I'm not a doctor and I only googled for 10 minutes. I tore my achilles last year. I would never take this drug. I hope I'm off base.
It's key to include false starts and promising paths that dead end. Learning to explore unknown solution spaces and refine the domain of the problem itself are critical skills in any open ended problem.
Spending an entire school lifetime being taught to "solve" "problems" and then being confronted with a world where problems aren't defined and solutions are ad-hoc and piecemeal is a rude awakening.
The strategies that made us a good students and made us feel good and smart in school aren't the same strategies that make for a good employee and those strategies set new devs up to fail when they can't "see the answer" to the current jira ticket they are tasked with.
How much of the leading edge of astronomy is ground based, vs space based? Are they complementary or is space based going to eventually assume any and all roles ground based could?
Electron hate is an entry in the genre, "modern software is inefficient and bloated because devs are lazy"
This genre will never want for new entries because, devs will keep getting things done and critics will keep complaining.
Electron hate is a moral argument, "devs are wasteful." It's not a technical argument. People confuse their ability to conceive of software which has the same behavior as shipped software, but improves on arbitrary figures of merit, excepting "date of RTM."
