Half right. Reducing ohms does reduce heat, but if you increase volts only on the input the power dissipation goes up by the square of voltage.

When you raise the voltage on both input and output (like high tension power lines) only the difference stays the same. In that case the heat stays the same but the amount of useful power getting through the resistance is higher so the heat is a smaller fraction of the total power getting through.

Maybe my imagination is too limited, but I am not sure whether this cute illustration helps explain any of that. Maybe we should spend less time pushing analogies through tight spots and relax.

There are various ways to assess the value of property, and taxing value can lead to distortions in the societal best outcome.

When I was a kid my parents were involved for awhile with a non-profit organization that had been gifted a property located in the coastal redwood forest in northwest California. the previous owner was a young man with little else than this land and the value of the land was inflated by the trees to the point that he could not pay the taxes on the land. Because he thought the trees were valuable in their existing location he did not want to log the land to pay for the property tax, so he gifted the land to the non-profit thinking that they could claim some loophole and get out of having to log the land, thereby saving the trees.

Unfortunately, they could not avoid the taxes and logging commenced. The loggers proceeded to start clear-cutting as they were used to handling the logging however they liked. But my dad figured out that the nearby river was a salmon spawning watershed and was able to get the Fish and Game officer to come stop the logging temporarily. It turns out that watershed status does not preclude logging, but there were rules about leaving a certain percentage of trees untouched, so the final outcome was a compromise.

There are a lot of situations like this, where enforcing a purely economic argument leads to poor quality outcomes. To be sure, billionaires use property ownership to dodge taxes, but so do a lot of non-billionaires. Covering every square foot of land with “productive” assets is not intrinsically better that leaving it fallow.

Slackware, around 1996 I think. Linux Router Project for quite awhile. Tried OpenSUSE, didn’t click, briefly tried RedHat, same junk, then tried Debian and it felt right. Later, got tired of purity over drivers that worked with the hardware I had and went to Ubuntu. Currently on Mint.

Color me mystified. Why would you map the verb of an English sentence to anything but a function or method in a computer language expression?

Neither Forth nor I are actions.

Well, in the absence of a higher power, such consensus-based practices are just your opinion about how things should be. This mod has been behaving like this for at least a year to my knowledge. I just avoid them.

agree. But mod decides what is appropriate for their group. even if they don’t hear any echoes because they are alone.

You seem to have missed my take on this as expressed in my second sentence.

You might find another take on this relevant in “Fur and Loafing in Yosemite” where a character named Velma Melmac attempts this approach to forest management. https://en.wikipedia.org/wiki/Farley_(comic_strip). Trump has in the last couple of years literally complained that California wasn’t managing to clean its forest floor properly in reference to wildfires there, suggesting that he completely missed the point of having the Velma character in that cartoon.

Then again, maybe humor is too alien for you. Lighten up.

Some people seem to be learning that their neighbors need to do a better job of cleaning their forest floor.

You can lead people to understanding but you cannot make them acquire it

I mean just that. Rows of solar panels on flat roofs or ground mounts are spaced just far enough apart that when beam illumination hits them that there are normally no shade from one row to the next… but that assumes that the light is coming from a well-known band of locations in the sky where the sun is. Strong differences in illumination cause PV to work as well as the lowest irradiance level, and in the case of beam-reflected irradiance from a rapidly moving source location that won’t be restricted to “where the sun usually is” and because there will basically be no significant diffuse irradiance from the satellite mirrors the arrays will frequently be suffering from unexpected shade which will make them terrible at converting the reflected light.

Beside the obvious diurnal health impacts, solar PV doesn’t work well when shaded and relies quite a bit on diffuse light to keep the array producing during those edge of day times when it is economically hard to make the modules spread out enough to avoid direct sun shading. Pointing reflected beams from arbitrary directions in the sky turns out to be very likely to create unusual shade lines that will render the light nearly unusable by the panels.

Then of course since they are planning to locate the reflectors in high-angular-velocity low earth orbit even if the angles are briefly conducive to power conversion it won’t last very long and then some fossil fuel generator is going to have to bobble their throttle to fill in the gaps… which is the worst possible scenario for using solar power (equal amounts of fossil generation as PV needed so no displacement).

Yeah, “unlimited” … as many as the allocated bandwidth will allow. But since the SMS is squeezed in between voice that is a very limited resource.

Because SMS is literally re-using bits dedicated to confirming that your cell phone is available for voice connections. There is a designed-in priority that has no room for expansion (since voice has priority in that scheme). To make your SMS connection look like it can handle stuff like photos, it uses the data connection as a side-band (“MMS”) and sometimes that fiction falls apart and the photos don’t come through with the sms it was supposed to be linked up with.

Not “next to”… “above”.

See a psychiatrist. You already have root on these systems… if you are truly a split personality then fences aren’t going to prevent your other self from doing whatever they want.

So stupid. My employer’s laptops given to every employee are pre-configured to vpn back to the company network. What part of “private communication” says this use case should be in any way distinguishable from some teen cruising porn sites?

IMO that depends fat more on you than on the movie. They had to change some things to keep it from ballooning to a far longer film than it ended up, so if you don’t like the choices they made them no. But if you are open to the fact that there are details that are just different and deductive chains of thought that are shortened drastically so they can emphasize other things, then yes it was worth it.

From the beginning of computing there has been a problem with bootstrapping knowledge… the person creating a tool gives it a name, and describes it, but knowing that someone solved the problem you have and what the name of that tool was always a challenge.

But that is nothing new… you posted in English but if you were to learn a different language you would have a very similar problem, and one of the most universal strategies for making that transition is to drill on vocabulary. Once you have built a small vocabulary then you can expand it using a dictionary.

The real message behind someone saying RTFM is that there are so many educational and search resources now that asking some rando on the Internet to rewrite a Howto on the fly is lazy. Simply typing the exact same question into Google will bring up a kickstarter set of vocabulary and resources. If you actually do this your question will often answer itself, and if it doesn’t and you start by pointing out why your efforts failed to help you with your specific problem and use the vocabulary (at least briefly) that your research turned up to guide the reader toward where your problem is, you should get less RTFM responses.
