On Tuesday 12 May'26, London's cycleway #C3 #CS3 on Victoria Embankment counter recorded and displayed 12,360 cycle journeys

The cycleway #C6 #CS6 Blackfriars Road counter recorded 8,288 journeys.

On Wednesday 13 May'26, the #C3 #CS3 counter recorded and displayed 8,961 journeys, after a day of frequent heavy rain, thunder and hail showers ⛈️

Sadly, there are plenty of reports that the rebooted totems don't work very well, e.g. in this morning's video shared on Bluesky, the C3 totem fails to increase as folk cycle pass and, at the end of the video, the totem reset the totals to zero.🤦‍♂️

[Перевод] Беззнаковые размеры: пять лет назад мы совершили ошибку

Краткое примечание для читателей, не знающих о C3: это язык системного программирования, продолжающий традиции C. В статье приведена специфика C3, но все плюсы и минусы применимы к любому языку, в котором нужно выбирать типы для размеров и длин. C3 переходит к использованию типов со знаком по умолчанию, но почему? Разве как минимум для размеров правильнее не использовать беззнаковые типы? Попытаемся ответить на этот вопрос.

Let's kill off half the builtins in C3 0.8.0

C3 0.8.0 버전에서는 기존의 여러 내장 함수들($sizeof, $alignof 등)을 제거하고, 이들을 대체하는 $reflect 빌트인을 도입해 컴파일 타임 리플렉션을 통합했다. 타입 프로퍼티 접근 방식도 int.sizeof에서 int::size 형태로 변경하여 명확성과 일관성을 높였다. 또한, 매크로의 가변 인자 처리 관련 여러 빌트인($vaexpr, $vacount 등)을 하나의 $vaarg로 통합해 간소화했다. 이러한 변화는 언어 표면을 줄이고 확장성을 높이며, 기존 기능을 유지하면서도 더 유연한 매크로 및 리플렉션 사용을 가능하게 한다.

IT-Sicherheit für politisch Aktive

Was ist eigentlich wichtig im Umgang mit Smartphones und Computer, wenn man politisch aktiv ist? Das besprechen wir diesen Mittwoch mit dem Chaos Computer Club in einem Workshop! Es gibt einen Input, wie wir im Alltag als politisch Aktive unsere Geräte sicherer gestalten können, im Anschluss Zeit für Fragen und Austausch.

🌗 C3 程式語言：無符號整數尺寸——一場歷時五年的錯誤
➤ 從無符號到有符號：為何預設類型選擇對系統語言至關重要
✤ https://c3-lang.org/blog/unsigned-sizes-a-five-year-mistake/
C3 程式語言在經歷了五年的開發後，決定調整其核心設計，將預設的記憶體大小與尺寸類型改為「有符號整數」（signed）。作者透過回顧 C 語言自引入 `size_t` 以來的歷史，分析了無符號整數（unsigned）在處理邊界條件、迴圈邏輯及運算子運算（如 `/` 與 `%`）時隱藏的陷阱。文章指出，儘管無符號整數標榜擁有更大的正數範圍，但其在溢位處理時往往會產生「看似合理但錯誤」的結果，且強制轉換（cast）帶來的複雜度反而增加了軟體缺陷。最終，C3 決定效法 Java 與 Go 的設計哲學，透過轉向有符號整數來提升程式的安全性與可讀性。
+ 這篇文章非常精彩！當年從 C++ 轉到 Rust 時，光是為了處理 `usize` 的強制轉型就讓我頭痛不已，完全能體會作者提到的「強制轉型地獄」。

Thanks to folk on Bluesky, we've a few days of journey data for London's cycleway #C3 #CS3 on Victoria Embankment:

> Tuesday 28 April: 11,952 journeys recorded;
> Wednesday 29 April: 12,782 journeys

(Video posted on Bluesky indicates that the refurbished and rebooted totems may not be recording 1/4 to 1/3rd of folk cycling past in busy peak periods).

Wednesday 10pm scores from @lastnotlost before another c240 folk cycled past.
