> not prediction based on anything statistical but based on one's understanding It is still statistical. You still want to predict a distribution over expected next token. However, the function needed to estimate the likely next tokens are not simple max over enumerated next tokens like in a language model. It's more like a transition model in reinforcement learning.

> It is still statistical. You still want to predict a distribution over expected next token. The fact that a process can be described statistically does not make the process itself statistical.

Quantum mechanics is probablistic. But the probabilities are deterministic.

"Do the Next Right Thing" is what I try to do.

This is effective because analysis paralysis is mentally draining. We tend to think/optimize in terms of time. But I've found it helpful to optimize for mental energy, which is often the limiting factor.

As someone with rural/countryside roots, I recall similar advice on physical labor: it is best to work at a steady, consistent pace all day long without getting sweaty or breathless . You'll avoid (or postpone) dehydration, remain more alert and calm, and thus it is much easier to switch tasks immediately. As a tree planter of several seasons, I've realized that this advice works remarkably well. Pushing yourself, sw…

This approach is actually best for learning/studying anything Eg. Martial Arts, Mathematics etc. Regular, Mindful and Consistent practice without over-straining is the key. Intensity should pick up only for key events likes Exams, Tournaments etc. and maintained only for a short duration followed by relaxation.

This carries over to social anxiety as well -- you tend to overthink what people think and such -- the more you do things the better you naturally get from experience as well.

If you're doing, do you have time to overthink?

My only gripe with TAOCP is its usage of MMIX.

If I where to ask “So what should he have used instead?” it would quickly derail this thread. There would be no consensus. Knuth probably foresaw this exact problem and more.

Yeah, if you read the intro to Volume 1, he specifically calls this out as an issue. I personally think he's taking a subtle dig at Numerical Recipes here, which did take the "modern" language approach.

Wonderful, thank you.

Why should the journey be orthogonal to the destination? The Bible confirms that both are vital. The Sermon on the Mount commands Christians to be kind, loving and good people in this life. Verses like Matthew 6:19-21, Colossians 3:2 and 1 Corinthians 2:9 compel Christians to live this life in light of eternity. To me, if you accept the presuppositions of the Christian worldview, this is logical. If this life and how…

> The Bible confirms that both are vital. Evangelicals just as easily claim the opposite, on the same conceit. "The Bible says". If this wasn't up to interpretation you wouldn't have so many protestant sects. For instance, being kind and loving could be construed as an obligation for Salvation, not a reflection of the importance of Earth life. There are a not-insignificant number that oppose utilitarian improvements…

> being kind and loving could be construed as an obligation for Salvation

It certainly can be and has been construed in this way and a proper exegesis of the New Testament has no other conclusion than that interpretation is patently wrong.

The book of Galatians (amongst) others is a clear rebuke of the heresy of salvation by works.

Those who oppose utilitarian improvements to quality of life ignore verses such as

"Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God."

"So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets."

"Let each of you look not only to his own interests, but also to the interests of others."

"Whoever is generous to the poor lends to the Lord, and he will repay him for his deed."

"Give to the one who begs from you, and do not refuse the one who would borrow from you."

"But love your enemies, and do good, and lend, expecting nothing in return"

The term "good Samaritan" comes from a Biblical parable highlighting the importance of being kind to others.

I don't how anyone can come away from a serious and accurate study of the Bible and not conclude that a Christian's conduct in this life is wholly important.

> ...it turns up in Philippians 3:16, where the writer says that: > "You don't race to get to the goal; the process of racing itself, of keeping the pace, is the real goal. When I go on vacation, I like to enjoy the drive." > In Christian churches I am least impressed by a sermon that talks about how marvelous heaven is going to be at the end. To me that's not the message of Christianity. The message is about how to…

So, Knuth wrote this rather unusual book called "3:16" in which he took every chapter-3-verse-16 in the Bible (where chapter 3 is too short for that, he continued past the end into chapter 4 in the obvious way), thought about it a lot and wrote down his thoughts, and also commissioned eminent calligraphers to render his translations of all those verses. (He was inspired, if that's the right idea, by the notion of str…

> It can't really be that we need to strive and strain in order to be saved -- Paul seems pretty opposed to that sort of idea, elsewhere. So the real point of the striving and straining must be the effect it has on our lives here on earth.

This interpretation appeals to me.
