Yes I would too. Over time I have come to appreciate at least being able to control order of operations, just forcing join order is many times enough of hint to keep things working properly. Having used Linq a lot I would actually prefer mo

I still have nightmares of SQL servers optimizer taking down production systems at random times due to picking a bad plan, judicious use of hints has made my life much easier and allowed me as a developer to be in control and not have to as

I haven't had much use for plan locking even after MS SQL server got it, even though its a nice feature with being able save load plans from a file etc. I just like good set of hints since they are part of source code and I can put com

PostgreSQL really needs hints. Sometimes I as the developer know better than the optimizer and having to trick the optimizer to get it to do what I want is a ridiculous situation. Also having the optimizer decide to do something bad off hou

You casually provide nothing contradictory to what I have stated and have multiple times dismissed power gain in antennas, electronic amplifiers have electronic gain, antennas have gain not dependent on electronic amplification, gain is the

Conservation of energy directly leads to the role of frequency in antenna reception and reciprocity: Figure 3.5: A cavity in thermodynamic equilibrium at temperature T containing a resistor R is coupled to an antenna, also at temperature T,

So while the transmitter can "shape the beam" to create gain, the receiver cannot (though the path lose equation implies that it does). The receiver can physically just trap the amount of watts per square metre that it receives a

"One key point is that in neither case is any amplification or "gain" present." "Antenna gain relative to an isotropic radiator is a thing." Which is it? Gain clearly does not mean amplification always as I poi

Please point me to precise language that describes antenna gain without using the word gain rather than making a vague declaration. You seem to be trying to pigeon hole the word gain to mean only electronics gain [1] while the word gain has

By default, power gain is what an RF engineer refers to when s/he talks about "gain." Really they never use that term with antennas without amplifiers? Seems like its all over the literature, again back to previous materia

> At the same time, as its size grows, the area of the antenna that's not exposed to the transmitted wavefront increases even more rapidly than the area that is, making it a losing proposition to keep increasing the size alone. And

"but the receiver has no gain, the energy it traps depends only on its area" Really no directionality, no resonance? Just make bigger area antenna out of whatever and it collects more energy regardless of geometry? Please go on th

It's actually pretty amazing to watch how quickly LiFePO4 batteries are dropping in price over the last few years and how much better they are getting. You can get a 12v 100ah drop in replacement for about the same cost as a high lead

Never heard of "put them out of their misery"? Not acting and letting them destroy themselves can be worse in many ways to them and others around them rather than "acting to kill them". This is a hard truth, I am not adv

Gasoline is burned at about 30-40% efficiency in cars while charging a battery is above 90%, probably over 95% (after the charger losses, that is whats going across the cable into car). So with a gas pump your looking at more like 7-8MW equ

I stand corrected, I thought HPCVC was 1000v at 3000 amps for 3 megawatts. However it looks to be 1500v at 2000amps to do 3MW.

EV chargers and cars are already up to 800 volts, to charge a 100 kWh pack in 5 minutes you need 1.2 megawatts which is 1500 amps. Chargers and batteries might go up to 1000v but don’t think there are plans to go beyond that at this point.

C rating still applies, charging at 1C is usually "fast" charging for most cells and that takes an hour, charging in 5 minutes is is 12C which is normally "bad", would need lots of active cooling. 50kw would take 2 hours

How does Windows solve that? Anything other than 2x multiples is lossy I thought.
