    Agree with sibling comment - the JS ecosystem has a huge momentum behind it and probably isn't going away anytime soon.

    On the web, Wasm has currently found the most success with compute-intensive applications, since the JS Wasm bridge is still pretty expensive. There are already some Wasm-based frameworks like that work on the web, but things like React/React-native and Flutter have a huge head start.

  • Is MAUI intended to be able to build serious desktop applications with?
    4 projects | | 25 Jan 2022
    Unlike other solutions like Uno Platform that also target Linux (as a Skia backend) and browsers (using WebAssembly), you can utilize MAUI and Blazor to target browsers. Not sure if there is a solution in the works to target Linux at all for MAUI.

  • Intel's New Chimera: Alder Lake
    4 projects | | 15 May 2022
    It was a bit more complicated than that: the issue was that one of the early big.LITTLE designs (Samsung's Exynos 8890) had different cacheline sizes on the big and little cores.

    glibc's `__clear_cache` would cache the cacheline size on first call, so if the program was started on a big core then migrated onto a little core it would only flush every other cacheline.

    And the mitigation was not to "change its allocation", it was to bypass libgcc and handroll cache clearing:


    And this issue didn't only affect Mono, it affected pretty much any JIT running on that phone e.g. dolphin ( and ppsspp ( had been hitting the same issue and adopted mono's fix, PPSSPP hadn't been able to find the root cause so they'd originally implemented a gnarly hack by adding a bunch of padding (

    But fundamentally this is the 8890 being broken: as the Mono post notes, technically nothing precludes core migration in the middle of clearing the cache, which would also lead to broken behaviour, with no mitigation.

    EB Whoa, wow, I could talk about this for a long time. So maybe I'll share a little bit of my own personal history. And for those who don't know me, I am not an engineer. Sadly, I've never been a developer. I actually studied Investment Finance in college. And I found open source in 2004, actually Wired published an article on Linus Torvalds, and Linux and kind of the rise of Linux. And I found it absolutely fascinating. And I was talking to a friend in San Francisco about it, who introduced me to a guy named Daniel Lopez, who became my co-founder. And Daniel was a very early member of the Apache Software community. He worked on Mono for those of you who remember it, and, you know, he was like this brilliant technical guy who obviously really understood open source and what was happening and how to build, and he didn't have an operational or sales background or like, hadn't built big teams before anything like that. And I had, and so he kind of invited me to start working with him, really, and I started by doing a few things. I remember I went and read all the open source licenses. And I was like taking notes for myself to understand how Apache compared to MIT compared to GPL. All these things just to try to understand the mechanics of that. And then, like, I just went on lots of forums and things to learn what people were talking about. This is kind of the days of the LAMP stack. But this all makes me feel so old. It goes back a long time.
