  • Tink

    Tink is a multi-language, cross-platform, open source library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse.

    Project mention: “Please do not make it public” (Tencent’s Sogou Input Method) | | 2023-08-09

    > I wonder what people say when they find a bug despite you using standard crypto?

    Not using TLS doesn't automatically mean you need to "roll your own crypto". They could have used a well documentend library such as Google Tink[1] instead of doing their own crypto.

  • QuestDB

    An open source time-series database for fast ingest and SQL queries

    Project mention: Leveraging Rust in our high-performance Java database | | 2023-09-20

    QuestDB engineer here:

    It's true that our non-idiomatic Java usage denies us some of the benefits typically associated with Java programming. Automatic memory management and the old "Write Once, Run Anywhere" paradigm are difficult to maintain due to our reliance on native libraries and manual memory management.

    I see two classes of reasons for choosing Java:

    1. Historical: The QuestDB codebase predates Rust. According to Wikipedia, the initial Rust release was in 2015. The oldest commit in the QuestDB repo is from 2014: What were the options back in 2014? C++? Too complicated. C? Too low-level. Pretty much anything else? Either too slow or too exotic.

    2. Technical: Java, even without GC or WORA, still offers some advantage.
