  • It makes total sense that new C++ will contain a higher percentage of bugs than old C++, but after being an almost full time Rust dev for the last two years, you will not convince me that new Rust code has more bugs than old C++ code.

    So far I have yet to come across a bug in any of my Rust code that made it into production. All issue reports from users are still related to the C++ code base that we haven’t managed to fully divorce from.

    The only advantage to C++ interop is that managers want to see new code get deployed immediately and continuously. They don’t want to wait until the corporation’s billions (literally) of lines of code are all rewritten in a new language before they start to see the benefits of that transition.









  • How exactly is an individual supposed to determine which cops will be good and which will abuse their power?

    Just as we can’t make a general statement that all cops are definitely bad, you can’t make a general statement that all cops in any particular country or town will be good.

    From a basic risk management viewpoint, it doesn’t make sense for anyone to accept the risk that any given cop won’t abuse their position, even if we were willing to accept that very few would actually do so.

    Cops have an extremely privileged status in society and the amount of damage that a bad one can do to an individual - on purpose or even by accident - is incalculable, including setting up an innocent person for capital punishment as we’re seeing unfold in Missouri right now.



  • Best practice when using .unwrap() in production code is to put a line of documentation immediately above the use of .unwrap() that describes the safety invariants which allow the unwrap to be safe.

    Since code churn could eventually cause those safety invariants to be violated, I think it’s not a bad thing for a blunt audit of .unwrap() to bring your attention to those cases and prompt to reevaluate if the invariants are still satisfied.




  • It’s a massive win, and I would question the credibility of any systems programmer that doesn’t recognize that as soon as they understand the wrapper arrangement. I would have to assume that such people are going around making egregious errors in how they’re using mutexes in their C-like code, and are the reason Rust is such an important language to roll out everywhere.

    The only time I’ve ever needed a Mutex<()> so far with Rust is when I had to interop with a C library which itself was not thread safe (unprotected use of global variables), so I needed to lock the placeholder mutex each time I called one of the C functions.




  • Yeah… I’m all for compassion and understanding, but if someone is missing the voice in their head that says “Hey, we shouldn’t be killing people” then their circuitry is broken, no matter what age they are or what their circumstances are. And that broken circuitry poses a real and present danger to everyone in that person’s orbit.

    I don’t support punitive incarceration, but the general public has the right to exist with a reasonable degree of certainty that they’re not likely to encounter a cold blooded murderer on any given day, and part of ensuring that is to incarcerate people who are known to kill others, at least until such a time that we can have a high degree of confidence that they won’t be doing that again.

    The person being a child doesn’t really change that part of the social contract. I promise you won’t be any less upset if someone you love is murdered by a child than by an adult.


  • One thing I’ve noticed among friends and family, who lean quite left compared to the general public and would be generally supportive of progressive policies, is that there’s a belief that progressive policies are unpopular outside of our circle and therefore in the primary they must vote for a candidate who triangulates in order appeal to the majority in the general election. Because a centrist from the Democratic Party is better than anything we can hope for from the Republican Party.

    I try to show them statistics that progressive policies are broadly popular across both parties as long as they are not presented with labels of “socialism” or “progressivism” but the reality that we all need to contend with is that we cannot easily escape the unfair baggage that these labels carry in our society where the big media cartel controls the narrative.

    I think if we got rid of FPTP and got rid of primaries we’d see an enormous swing in favor progressive candidates. In my mind that electoral reform is the key thing to pursue. Well that and literally anything related to mitigating the climate crisis because that one really can’t wait.
