本文揭示了排版领域一个令人惊讶的事实：LaTeX 和 Inkscape 虽然都使用"点"（pt）作为度量单位，但两者定义不同。LaTeX 采用传统印刷点（1/72.27 英寸），而 Inkscape 继承自 PostScript 的计算机点（1/72 英寸），两者相差约 0.4%。文章追溯了点作为排版单位的混乱历史——从 16 世纪诞生至今，不同国家、不同技术体系对"点"的定义始终未能统一，从 NIST 的官方定义到 Donald Knuth 在 TeX 中的微调，再到 W3C 标准的选择，这段历史充满了测量精度、标准化妥协与技术传承的有趣故事。
Partial static single information (SSI) form is an intermediate representation between SSA and full SSI form. It places σ-functions only at join points where different values converge, reducing overhead while retaining useful properties for optimization and analysis.
Simon Willison created an experiment demonstrating how a web app running inside a CSP-protected sandboxed iframe can use a custom fetch() to intercept CSP errors, pass them to the parent window, and allow the user to add that domain to an allow-list and refresh the page.
Partial SSI is a simplified alternative to full static single information form that inserts type refinement nodes during SSA construction or optimization rather than implementing complex SSI algorithms. This approach lets compilers propagate type information from conditionals and guards to enable optimizations, as demonstrated in projects like ZJIT, Cinder, and TruffleRuby.
