The amount of money you save (and invest) isn't accurately depicted with this though. Living expenses don't necessarily grow with take home, if you keep lifestyle creep to a minimum.

So what this means is that if you make $100k and save $10k/year, if you start making $200k you can save the same $10k/year, plus the entire additional $100k after taxes (let's just say that's $50k+). So you doubled your salary but your savings went up 6x+.

Not sure why you're saying Python forces everything to be object oriented...?

Wouldn't 25 year olds still be in school for their doctorates though?

Yes, I think that's the point


they skew the numbers upwards.

"Chain migration" is how many people


myself included


get jobs.

I went to a very good school, and while I like to think the quality of education is what makes a school "good," let's be honest


the value is largely in your connections. Friend lands a good job, recommends you when there's an opening, and bam, you're already at the top of the pile of the CVs (better yet, they're the hiring manager).

Friends from school


peers and mentors alike


are a great place to start, if you can. Ask to grab a coffee and chat about their career, and be clear that you're in the market. Most people are happy to chat (at the very least, it's flattering).

It's the way the world works...

I particularly like the truck/engine correction.

But "included" doesn't mean free. You still paid for it.

Baking is chemistry, cooking is jazz.

I'm curious how the battery percentage went up

Physicists hate this one weird trick...

[–] qjkxbmwvz@startrek.website 4 points 1 week ago

Is that true though? As in, is it really that dangerous? It seems that you'll dissipate power equal to the inefficiency times the nominal charging power, so something like 5V x 2A x inefficiency (inefficiency being 1-efficiency), which will probably be of order a watt.

I can use my car battery to charge itself without any issues


I just plug the red terminal to itself, and same with the black, which is to say, a battery is always connected in a way that "charges itself."

I think the key is that the battery probably isn't really playing a big role in OOP's setup


electricity doesn't "go through the battery," it just goes from the charging input to the power output circuits, with the additional power (due to inefficiency) being provided by the battery.

I'm not sure though


the power output and the charging input are both regulated and (almost certainly) current limited. So I think (not positive...) that you're basically dissipating your power in the inefficiency the charging and output circuits, with this power coming from the battery.

The inefficiency should (I think...) just be the round-trip inefficiency of the charging/discharging of your power bank


this should be way, way less than the short-circuit power dissipation.

The simplest toy model is to take a battery and try to charge itself. So you put jumpers on the + terminal and you connect those to the + terminal, and same for - (charging is + to +, NOT + to -). But this is silly because you've just attached a loop of wire to your terminals, which is equivalent to doing nothing. With charging circuits in between things get much more complicated, but I'm not sure if it goes full catastrophic short...
