Thanks for the reply, I’m still curious though

> cycling is just usually a good way to maintain a temperature when you've got a pan and some food sitting on top of it since there's quite a bit of inertia in actually changing the temperature of whatever is on the stove.

Why precisely is cycling more effective than attenuating down (better word please?) the output? I don’t see what the thermal inertia of what’s on the cooktop has to do with making the optimal (for cooking) choice between cycling and modulating the power.

Without detailed knowledge of the precise energy and time costs, I think it’s a fair default assumption that continuous power modulation should be more efficient, because it’s in a sense a superset of cycling, with much more fine grained control, but you can always set the continuous power output to 0 or 1 to accomplish cycling if in a specific scenario it is helpful.

Maybe when you say “a good way” you mean “a good enough way”? That makes sense, but doesn’t really sell induction stoves relative to gas (if you want to sell induction stoves relative to gas, I suggest to downplay any cycling and promote the continuous output modulation)..

Would you spell it out for us? If induction cooktops are capable of continuous control of their output, why do they cycle significantly in set temp mode? At least, I would expect them to cycle minimally for fine tuning, relying on the continuous control of output as much as possible instead of cycling.

He doesn’t have to state this. Look at his work.

For sure, also I don’t assume people know much about Knuth or expectations for academic work.

(In his digestive summaries, Knuth does provide citations, to be clear)

The data is currency though, in the pirate economy.

Nothing to brag about, sure, but still remarkably good in comparison with calls today. Latency aside, the quality of copper POTS was still capable of being much better than, for example, my new iPhone making cellular calls on AT&T’s network. (I prefer FaceTime Audio)

Isn’t the biggest contributor the discrete transition from circuit-switched copper to packet-switched data? You imply some sort of gradual erosion..

But anyhow yea, kids today will never know the special intimacy yielded by the low latency of a circuit-switched landline call.

Volume 1 served me a decade+ ago as an approachable survey of the history of computer science up to that era- super useful and enjoyable!

What did you find in it?

The best neighborhood in Oakland (which I will not name).

I live in a mid density city with a nice ambient hum. Indeed the neighbors in my building are respectful, as are the neighbors on either side. But I think the ambient hum is key to the peaceful atmosphere, when living in a city. The biggest threat we’ve experienced in terms of noise is blue jays that I finally staved off after months, by occasionally assaulting them with a super soaker. Other birdsong is pleasant, I hear some right now and open the window wider.

I say this as somebody fairly particular about my comfort. I can’t stand interior transformer hums for example.

My personal preference is deeply in the natural ventilation camp, and the typically delicious air we have in the Bay Area is a boon to my wellness. I leave the windows mostly open 24/7 three seasons, and in the winter I partially open them during significant portions of the day. It’s wonderful.

But during the worsening wildfires seasons, I must tightly seal and air purify my apartment for weeks straight, and had to buy an air conditioner that I run during the day. The stale air is unpleasant, but unavoidable.

How idiosyncratic are my preferences and environmental circumstances? Are any architects working on house designs for me?

I’m as big a Tesla hater as anyone, but you should know this is pervasive with new cars. My 2021 Outback for example has garbage UI, plus lots of smart features, so also has a steep learning curve.

Thanks for pointing out the improvement over NIST, it wasn’t clear to me. But did you mean to reply to my parent? Both the draft and the current language say SHOULD NOT. I’d rather “must”, but will settle for “should”; the NIST docs have certainly made my work easier. Hopefully NIST improves, and perhaps this memo will help!

The essential purpose of my comment was only to correct my parent on the date.

Way earlier than that, even.

> Verifiers SHOULD NOT impose other composition rules (mixtures of different character types, for example) on memorized secrets

Earliest draft in Wayback Machine, dated June 2016. Lots of other good stuff from 800-63 dates back this early too.

Thanks! Point taken that my garbage query yielded garbage results.

Coming full circle here, in your opinion, are pluggable storage engines a virtue of MySQL, for practical purposes?
gkop

That’s good to know!

If the first result is not reputable, that’s still a smell (but a different kind of smell) for MySQL. https://duckduckgo.com/?q=innodb+vs+myisam

Let the containers on the streets piss people off to build pressure to align incentives, rather than prolonging the problem with a temporary stacking improvement. This is just a tool in our toolbox that we should not ignore, I'm not saying it's the right tool. But there is a cost of papering over the root cause, that's not free.

BTW I don't live in LA/Long Beach. I recognize that LA doesn't deserve the quality of life degradation, that's an externality. We have tools to resolve externalities. I could imagine living in an affected neighborhood in LA and being super grateful for the container stacking "quick fix".

I should have given more context. In cases where incentives are deeply, structurally misaligned, and it will take heroic effort and significant luck to yield an order of magnitude improvement over the status quo, we should consider "letting it burn" as an option, and recognize the total cost of treating the symptoms. The global logistics quagmire may be a candidate for nuclear-ish options. Agree with you on the cancer patient scenario.

Counterpoint, sometimes it's better to let the system burn, or else the root cause will never be addressed. Treating the symptoms can take the pressure off solving the root cause.
