🌘 C++26：std::optional 的範圍（range）支援
➤ 為 std::optional 注入範圍語彙，打造更簡潔的 C++ 程式碼
✤ https://www.sandordargo.com/blog/2025/10/08/cpp26-range-support-for-std-optional
C++26 將為 std::optional 引入範圍（range）的支援，這項重大更新讓 std::optional 的物件本身也能作為一個最多隻包含一個元素的範圍來使用。此功能極大地簡化了在組合式程式碼中處理可能不存在的值的邏輯，能夠無縫整合至現有的範圍管線中，自動略過空值，無需手動進行 if 檢查，從而提升了程式碼的可讀性與效率。
+ 這個改動太棒了！再也不用寫一堆 `if (opt)` 了，直接用 range-based for loop 處理，程式碼瞬間清爽很多。
+ 一開始覺得這有點多餘，但看到 P3168R2 的範例後，發現它在處理連續的 range 操作時，確實能大幅減少樣板程

Встреча ISO C++ в Софии: С++26 и рефлексия

Привет! На связи Антон Полухин из Техплатформы Городских сервисов Яндекса, и сейчас я расскажу о софийской встрече Международного комитета по стандартизации языка программирования C++, в которой принимал активное участие. Это была последняя встреча, на которой новые фичи языка, с предодобренным на прошлых встречах дизайном, ещё могли попасть в C++26. И результат превзошёл все ожидания: compile-time-рефлексия рефлексия параметров функций аннотации std::optional<T&‍> параллельные алгоритмы Об этих и других новинках расскажу в посте

🌘 使用 Token 序列迭代範圍
➤ 剖析 C++ Ranges 的效能隱藏陷阱
✤ https://brevzin.github.io/c++/2025/04/03/token-sequence-for/
本文探討了 C++ Ranges 庫中，某些 range adaptors (如 `views::filter` 和 `views::take_while`) 在迭代範圍時可能產生的額外效能負擔。作者分析了這些 adaptors 的 desugaring 過程，指出它們在實現自定義行為時，即便看似能完美契合迭代器模型的定製點，卻可能引入不必要的比較操作，甚至重複計算。此外，文章也討論了 `views::reverse` 的實現複雜性及其可能帶來的效能問題。
+ 這篇文章讓我更瞭解 Ranges 庫的內部機制，以及在使用上需要注意的潛在效能問題。以前我總是覺得 Ranges 很方便，但沒想到有些 adaptor 會帶來意料之外的開銷。
+ 作者分析得非常透徹，用具體的例子和 desugaring 過程來說明問題，讓人更容易理解。對於想深入瞭

@LibreKitsune I still consider this a hostile act and a blatant violation of their previous #settlement that forced them into #publishing said #IPv4 #ranges...

• In fact had they not actively worked against that previously and it only raised my attention when I saw errors re: said ranges.

I'm considering to build a #workaround on #GitHub to just use a #cookie and some #compute to do it, but if I had cash to spare I'd sue them into removing #ClownFlare and allowing me to scrape the list directly...

• I'm very close to just sending them an #invoice for the personnel hours wasted on that bs and billing them regularly for the expense of manually checking the difference between those (@ minimum of 60:15 billable minutes)...

Otherwise I do expect regulators to actually go after #OpenAI and force them to undo the #Cloudflare-based #Enshittification, since it's neither feasible nor reasonable to claim "#DDoS-#Protection" for a 48 Bytes (!!!) file...

• Every #WAF / #WebApplicationFirewall I know would not get triggered even if I were to query it once per hour (which I now do just to annoy them or rather ClownFlare!...
