Instead of direct trivia from the content, it would be helpful to have an exercise (with evaluation) that applies the content learnt - a small artifact production with real-world practical use.

Imagine you would need, another ai pipeline that poses as the consumer and applier of the knowledge, instead of a direct processor ai of content information as it currently seems.

Do you always need that kind of prolonged argument whenever you learn a new concept?

> Sometimes the YouTube video is more helpful than the private tutor.

University lectures work like that. First the general lecture, which has 300 students and is not interactive. Then the tutorial, where students who want extra help can consult individually with a TA. Attendance for tutorials was typically much lower in my experience, because a lot of students thought the lecture was plenty and wanted to spend the time on something else.

Except the argument is university lecture (classroom structure) doesn't work. A personal tutor might be able to teach a concept to all their students, whereas not everyone in a classroom passes. Your argument about sufficiency can be made about books and is not relevant here.

I don’t think that holds for everything. Industrial 3nm chips are probably better than whatever you would get if people tried to DIY this. Lots of things get better with scale: materials, precision machinery, process efficiency, power generation.

But there’s also plenty of things that don’t work this way. Care is one of the most extreme things that does not.

for eg, asic custom designed for an application is better than a generalised industrial chip

> Scale isn’t bad, at least not necessarily. Industrial is perfectly capable of being better than custom. Sometimes the YouTube video is more helpful than the private tutor.

This is not true; consider the argument that there is always a loss of quality in scaling. Industrial maybe better than average custom, but is always worse than best customs. Broadcast lecture is almost always worse than a tutor whose discourse is customised to student's current knowledge. (The word guru (literally, one who leads towards light) is wrongly translated to teacher, for which the word in sanskrit is shikshak.)

Something one might like as a continuation of the article is digital sundials. Apart from types listed on wikipedia, there are 3D-printed versions etc.

>> They're wrong most of the time but it's a numbers game.

I'm not sure you meant to communicate this VERY important point, this is a huge reason NOT to do YC.

This is not a reason not to do Yc, but to not take the if rejection seriously

a personal pet peeve (brace yourselves, it's pedantry):

Technically speaking, we're talking about four dimensional space. It doesn't really make sense to call such a space "The Fourth Dimension", any more than real life space is "The Third Dimension", or a tabletop is "The Second Dimension". This sometimes trips people up into arguing over whether The Fourth Dimension "is" time, or whatever. For that matter, maybe the first dimension is time, and the second, third, and fourth dimensions are space. These things aren't ordered, and in fact you can't really distinguish between the three familiar spatial dimensions: imagine trying to point along dimension one, whatever that means.

The familiar three-dimensional space as we know it is three dimensional because you can put three straight lines to meet at right angles to each other, and no more. And you can label those lines x, y, and z if you like and pick their orientation. Four dimensional space allows you to cram another in. Two dimensional space only allows two, and one dimensional space is just a single line.

Its not that simple. Time it seems IS the first (0th?) dimension. A point is space denotes existence in time of the object & observation by the subject. In other words, rate of change of existence is observed as time. Rate of change of a point is observed as a line. A moving point accepts line as its track, moving interval accepts square as its track and moving square accepts cube as its track. 2-eyed observer has 3D vision & 1-eyed observer as 2D vision (try touching your fingers with one-eyes closed exercise) has some role about role of observation as well.

Further, dimensions being relative vs absolute makes more sense. In absolute sense, time is its own dimension T & point line cube are L, L^2 & L^3. A 3D object, a cube, has 2D object, plane, as its boundary & 1D object, lines, as its dimensional denotion. A square has 1D object as its boundary & n-2=0D objects, points, as its dimensions, relatively speaking. This is important because of the number of eyes? So basically, those 2D hypothetical characters in your physics are 1-eyed creatures, lol.

Prompt engineering doesn't feel like an activity that creates sustainable AI advancement. A prompt may work well with one model, in most situations, but even the best practices seem too experimental.

For their competition to avoid a PR disaster, isn't it better to look in the model? Perhaps observe the weights, when the AI says something that you want to avoid in the future. A safeguard could trigger if the model is going in that direction.

Chatgpt was created from gpt via prompt engineering? An inverse chatgpt where user answers questions instead of the other way around also has applications.

Nice, but since each pixel consists of a solid-filled greyscale rectangle (or emojis, I guess?) and doesn't take advantage of the shapes of characters, the resolution seems limited compared to the ASCII art of yore (or even the output of aalib).

It also doesn't have any Dickbutt images and this is a crime against Dickbutt.
