This is all based, most likely, on Griffiths' textbook. Quoting here from this post https://www.reddit.com/r/Physics/comments/1b97gt/magnetic_fields_do_no_work_but_magnetic_cranes/ :

The statement "magnetic fields do no work" is incorrect. Griffiths has mislead a generation of physics students on this. A correct version of the statement is that "magnetic fields do no work on objects with no magnetic moments" which is rather trivial. One could also correctly make the same statement about electric fields. However, electric monopoles are very common, so a situation in which there are no electric moments never occurs in normal circumstances.

tl;dr: use Jackson ;)

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+.

Who the fuck said we had to choose either?

They did, and pointing that out will (I'm guessing) be met with some form of covering their ears and saying "nah nah nah I can't hear you."

Verizon will tell you to fuck right off and will never unlock your device.

Will never unlock their device.

The beautiful thing about this is that for both the pro- and anti-systemd crowds, it only reinforces their respective opinions.

(Aside, I used to use postgres for date/interval calculations...)

Wouldn't be surprised if he thinks the bad guys won the American Civil War, too...

if the Democrats truly understood the minimum wage would be $20 or more

In Democrat-controlled California, the minimum wage for fast food workers is $20: https://www.dir.ca.gov/dlse/minimum_wage.htm

Maybe. Or this will play out like Slack and IRC.

Initially, Slack integrated with IRC. Which was great! It meant I could use xchat to talk with folks, and could set up simple bots using standard IRC tools.

And then Slack killed that feature...but it absolutely didn't kill IRC, because die hard IRC users never cared about Slack in the first place.

My prediction is it'll be the same


what sort of people will be attracted to Threads vs a smaller "proper" instance? Probably the sort of people who would never consider a federated platform in the first place.

Just speculation and I could certainly be wrong...

Googling around it seems a 21" draws around 100W, which isn't as much as I thought; it's kinda a florescent light with more steps. A florescent backlit LCD doesn't use a whole lot less, and a modern 30-something inch LED backlit uses, as far as in an tell, about 1/3 that. So, for typical sized monitors, only ~70W more for CRT.

In contrast, the GPU wars mean that (I think?) power consumption in gaming desktops has gone up somewhat substantially


a 500W PSU was fairly beefy in 2003 (I think), whereas 1000W or more is pretty standard for a gaming computer now (obviously it's not drawing rated power, but assuming headroom % is roughly the same...).

My completely unsubstantiated guess would be that a LAN party setup as pictured would draw more power at idle, but a modern LAN party would draw more under load.

Nine people= voting population of USA

Three vote to drive off cliff = MAGA plurality

Two vote for ice cream = Biden voters

Four abstain because it's shitty ice cream = abstaining voters who presumably don't want to die but also don't want shitty ice cream

If that's painfully stretched, I would like to see your definition of a straightforward metaphor...I guess "life is a rollercoaster" must take some PhD level analysis to understand.
