挖到一个相当硬核的 GitHub 开源项目：《网络代理与 VPN 应用详解》。

要是你天天在用 Clash、Surge、V2Ray、VPN，却始终没弄明白代理背后到底怎么跑起来的，这份文档很值得翻一翻。

它从代理、隧道、VPN 这些基础原理讲起，一路往深里挖，讲到 IP／端口封锁、DNS 污染、TCP RST、SSL 连接阻断这些网络封锁机制，不少地方还配了图解和实例。

刚接触网络代理、想补底层知识的人，建议先收藏，慢慢啃。

Excited to share that our review has been published in @angew_chem!
We summarize recent advances in deep-red to near-infrared light-driven radical generation and discuss future opportunities for low-energy photochemistry. https://t.co/ogX5jafSk4

In the DeMayo reaction, the enol of a 1,3-dicarbonyl and an alkene undergo [2+2] cycloaddition. Retro-aldol of the resulting cyclobutanol yields a 1,5-dicarbonyl.

This has been applied in the #TotalSynthesis of (±)-Longifolene by Oppolzer & co-workers.

Rule breaking continues!

Our latest work with the Paton Lab @bobbypaton shows how tuning electronics controls [2+2] photocycloaddition regioselectivity, enabling selective access to distinct aza-bicycles.
