我们平时在大厂的项目总结和一些作品集案例中，会经常看见和视觉动线有关的讲解和说明，虽然大家可能对它有个模糊的概念，但并不知道具体怎么应用和分析，所以今天这篇干货，就是围绕视觉动线进行具体的解释和分享。

颜色控制一直是AIGC的难点，prompt会污染、img2img太随机… 今天带来利用controlnet，实现对画面颜色的有效控制。都说AIGC是抽卡，但对把它作为工具而非玩具的设计师，必须掌握如何控制它，让我们一起开始可控AI生成。

本文将给大家分享一个解决问题的流程 ，并增加真实案例以便大家加深理解。当我们掌握并熟练运用好“流程”后，定义问题、分析问题、解决问题的能力及效率都能有所提升，进而完善自身的数据分析思维。

We’ve recently open sourced a project called Ruvy! Ruvy is a toolchain that takes Ruby code as input and creates a WebAssembly module that will execute that Ruby code. There are other options for creating Wasm modules from Ruby code. The most common one is ruby.wasm. Ruvy is built on top of ruby.wasm to provide some specific benefits. We created Ruvy to take advantage of performance improvements from pre-initializing the Ruby virtual machine and Ruby files included by the Ruby script as well as not requiring WASI arguments to be provided at runtime to simplify executing the Wasm module.

WASI is a standardized collection of imported Wasm functions that are intended to provide a standard interface for Wasm modules to implement many system calls that are present in typical language standard libraries. These include reading files, retrieving the current time, and reading environment variables. To provide context for readers not familiar with WASI arguments, WASI arguments are conceptually similar to command line arguments. Code compiled to WASI to read these arguments is the same code that would be written to read command line arguments for code compiled to target machine code. WASI arguments are distinct from function arguments and standard library code uses the WASI API to retrieve these arguments.

At Meta, we are constantly innovating and experimenting by building and shipping many different products, and those products comprise thousands of individual features. As part of this healthy technology lifecycle, it is inevitable that certain products or features will be deprecated. For example, in 2015 we launched a photo-sharing app called Moments, which was later deprecated in 2019. So, how did we efficiently and safely remove all of the code and data related to Moments without adversely affecting Meta’s other products and services?

In this three-part blog series, we will discuss the complexities involved in removing a product from a complex portfolio of products and the framework Meta has built to drive the automation of this process, our Systematic Code and Asset Removal Framework (SCARF). SCARF has had an important impact at Meta. In the last year, it has removed petabytes of unused data across 12.8M different data types stored in 21 different data systems. Over the last five years it has deleted over 100M lines of code.
