  • Nuclear and solar have competing problems. Nuclear is a baseload generator. It can’t ramp up or down fast enough to meet the daily demand curve; it needs a steady, stable load, 24/7. The steadier and stabler the load, the better. If the load drops off overnight, nuclear has to dial back its continuous output to match that trough. And again: It can’t ramp up and down fast enough to match demand, so it just has to stay at the lower “trough” level, with the remainder made up by various types of “peaker” plants.

    To make nuclear as efficient at possible, we need to drive consumption to that trough. We have to increase overnight demand as high as possible, to minimize our reliance on inefficient peaker plants.

    Now, look at solar. Solar stops generating overnight. Solar can’t possibly meet overnight demand without storage, and grid-scale storage solutions are fundamentally limited. To make solar as effective and efficient as possible, we have to move as much demand to daylight hours as possible, where it can be met directly by solar generation, without storage.

    The two technologies require opposing demand incentives. Making one more efficient necessarily makes the other less. Whichever choice we make here, the other one is relegated to a limited, auxiliary role in generation, and can never reach its full potential.











  • I start typing in URLs that aren’t linked anywhere on the site, then I’m accessing stuff the site hasn’t explicitly indicated I have access to.

    Doesn’t work like that. With the policy you describe, anyone who ever sees a “404” error is a criminal.

    I don’t have to publish everything I am willing to offer. You are free to ask for something I may or may not have. I get to decide how to respond to your request.

    To use your analogy, I can walk up to your door and request a glass of water. You’ve never explicitly offered a glass of water to anyone; I’m still allowed to ask. If you dont want me to have your water, you can say “No” or you can ignore me.

    When you go ahead and give me a glass of water, you don’t get to claim I stole it from you. It is not theft to ask.

    You have to make some sort of effort to have your web server limit my access, and I have to make some sort of effort to convince your webserver to bypass those restrictions before you can claim I am exceeding my authorization.


  • Terrible analogy. A webserver is not at all like a door. It doesn’t block or allow traffic to and from your file system.

    A web server is more like a receptionist. It handles requests. “Can I have your basic catalog?” “Certainly, here you go.”

    “Can I get this item from your basic catalog?” “Certainly.”

    “I don’t see it in your catalog, but my buddy said he got this other item from you. Can I have this other item too?” “Absolutely.”

    “Can I borrow your stapler?” Sure. “How about a pad of paper?” “Of Course”. “Can I just have the contents of your supply closet?” “Here you go.” “How about your accounting files, can I get those?” “No problem!” “How about your entire customer list?” “Consider it done!”

    When you hire a receptionist and specifically tell them to give customers anything they request, that’s entirely on you. You have to at least make a token effort to restrict access to only authorized users before you can even claim that a particular user was unauthorized.

    This wasn’t burglary. This was putting up signs that say “come in” and labeling everything in your house with “free” stickers.



  • Gotta be at least 60 degrees at a time, or you can’t reset the wrench to the next position.

    Open end wrenches for external hex bolts are usually cocked 15 degrees so you can do as little as a 30 degree swing. Flipping the wrench switches the head from 15-degree left, to 15-degree right. Adding the 30 degree swing gives you a total of 60 degrees, which mean you can grab the next face on the bolt.

    But Allen wrenches don’t have such a feature. You need at least a 60-degree rotation before you can reset the wrench.
