If you nest two grids, the rows and columns of two sibling grids are not forced two align. With subgrid the rows and columns of two sibling grids are aligned with each other by glueing them to the rows and columns of the parent grid.

With nested flexbox the nested dimensions are not aligned to each other. With grid the items are aligned across both each row AND each column. With subgrid even nested grids can be aligned across nesting levels.

My favorite Bret Victor talk ever is „Drawing dynamic visualizations“ [1] that made me try to reverse engineer [2] the demonstrated tool that he sadly never released. [1]: https://youtu.be/ef2jpjTEB5U?si=S7sYRIDJKbdiwYml [2

Say you want to do obj.child.foo[3].bar += 2 but without mutation, but instead all the data is immutable and you need to do a deep copy along the path. Lenses are an embedded dsl for doing this via syntax that reads similar to to the mutabl

Yes functional lenses are very good at transforming between between schematas. You can think of it as an functional programming based embedded domain specific language for transforming immutable data structures into each other. Sure there a

Yes lenses are pairs of functions that allow bidirectional data transformations. One function acts like a getter and one function acts like a setter. The signatures of the functions are designed to compose nicely. This allows to compose com

This is a very simple example in svelte [1] This is very detailed introduction and documetation of a lense-based architecture in react. [2] At the first glance it looks kind of overwhelming but it contains lots of examples. This is a case s

In my experience when applying this architecture to react or svelte, the performance is quiet good, often better than classic alternative approaches (redux, many local useState) But the main benefit is not only the persistence of the app st

by laszlokorte 1y ago
With lenses its possible to create component interfaces that make local and global state interchangeable. Even for focus, selection, scrollposition components use local state by default but that can replaced by a lense into a global state.

Yes because Elixir is such a nice language. In every language there are sharp edges or dirty corners that are just annoying once you hit them. JavaScript and Php are full of inconsistencies, Ruby and Python are nice and the surface but once

Are these kind of projects actually build manually inside of minecraft block by block or is there some verilog/vhdl to minecraft-level compiler toolchains used?

by laszlokorte 1y ago
No, because they dont define the >>= operator (which is the one to be associative) in the first place.

I am glad you like it! Yes the simplest way to think of it is to exponentiate the dft matrix to an exponent between 0 and 1 (1 being the classic dft). But then the runtime complexity is O(n^2) (vector multiplied with precomputed matrix) or

The implementation shown in the video is actually particularly slow because all the geometric transformations are implemented in terms of lenses/optics ([1]) and ramdajs ([2]). So the whole mess is a gigantic stack of nested, composed

Very cool! Just just implemented an SVG 3D renderer a few weeks ago [1]. But I did not implement texturing yet and wondered how one could do this. [1]: https://youtu.be/kCNHQkG1Q24?si=3VxfVFtG2MiEEmlX

What would be the corresponding syntax for matching and flipping only the first Posn? If I had to guess: fun flip_all([Posn(x, y), rest]): [Posn(y, x), rest] If I am correct then the only difference between flipping all and flipp

I currently have the same issue while building a canvas web app. Safari shows a small magnifier glass on double tap/long press and none of the css properties will suppress it.

By skimming docs I notice that you use <%- %> tags for outputting un-escaped strings. In contrast ERB uses <%- and -%> for trimming leading and trailing whitespace of the surroundings. In security sensitive context of escaping o
