Amazing! This is the most useful calculator.. bit shifts..radix conversations...

I've been using it for years after struggling missing the windows 2000 calculator.

borner791··on A mechanic offered a reason why no one wants to work in the industry
keep in mind a good mechanic is making double time or better.. although I understand that's harder on a FORD than a Japanese car.

$20 is also on the low end for a good tech, you're correct.

Balancing.. thats probably 1-0.5% of the BESS capacity. The impedance of LFE cells are so high when charged pretty small amounts of energy can slosh around before a protection disconnect, over voltage for example

Prius is just a little gas engine in a little and aerodynamic car.

They can have a tiny gas engine because the electric helps acceleration from a standstill.

The batteries are just weight on the highway

borner791··on American megachurches are thriving by poaching flocks
I went to one in LA, extended family went for Xmas. It's weird, super produced. The back wall was a teleprompter and a timer, so they could time this service and start the next.

I don't go to any church, so this was extra over the top.

borner791··on Reddit subs with millions of followers plan to extend the blackout indefinitely
I really wonder if it would be better to go the other way.

Mods take a break, and just let the bots shit allover the content.

It takes like 20mn of un-moderated internet before it's all ads and spam... Reddit is basically reddit because of the carefully curated posts.

In 10 years as a "professional" I've never heard it until the last 6 months. I'm EE so different circles, but closer to pure SW people in those last 6 months.

I'm not a fan.. I don't know why.

borner791··on Systems Engineering, or "why james gets paid"
Where do you sit in the organization? How do you "get ahead of projects"?

Im a Systems Engineer by title, but have no idea where my place is (its all confusing). I'm basically an 'super IC' on a team - and try to play with other groups my group interacts with... So there is no power to set the design. Basically just answer 'will this work with your part of the system'?

I basically end up just finding issues, POC end-to-end (well outside of my discipline: I'm a HW guy to I'll do a FW to Cloud security thing).. and well, why business does the HW Systems person have suggesting we use PKI for authentication?

borner791··on That UPS you bought for your home server may not be as useful as you think
It's more complicated than that. There are Smart-UPS online. Thats double conversion also 0ms transfer

Some of the "newer" online models will have a green mode, which although double conversion green mode introduces a transfer time (~2ms, basically relay lift time).

Backups are also square wave, or stepped sine Smart are Sinewave output.

This is specifically APC.

Also remember there are tare losses (copper / magnetizing and conversions), so a UPS just sitting there can use up to 30W.
