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.
But only if pattern matching were included, otherwise they would be as unpleasant as C++'s std::variant.
This makes a lot of sense, but the functions were Rust bindings for plain C functions, they weren't function pointers. Granted I could have put pointers to the function bindings into fields in a struct and stored that struct in the mutex, but the ability to anyhow call the bindings would still exist.
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.
I honestly believe the two are related. I think big meat agro business is paying influencers to promote toxic masculinity and push nonsense like "plants emit toxic hormones" on social media.
Valid questions. Do we have firm answers to any of them? And absent firm answers, what kind of risks to the safety of the general public are we willing to accept in service of ideological values?
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.
I assume he thinks this will win over more Gen Z than it will lose him Boomers, and no one will ever hold him to this promise anyway.
Countries ranked in descending order by number of school shootings from 2009-2018:
One of these is not like the others. This isn't exactly a fact of life in other parts of the world.
People just don't want to believe that China can win at capitalism because it undermines all their internal narratives around the innovation power of liberalism. I say this as someone who does not personally like China and its authoritarianism.
The fact of the matter is with a population of nearly 1.5 billion people, you're statistically guaranteed to have enormous pools of talent to draw on. Even a relatively modest per capita investment in education, focused on key objectives and funneled into the portion of the talent pool that they've managed to identify, will be able to yield massive innovation.
A lot of people will suffer under this authoritarianism. The people from these talent pools will be exploited and burnt out at a young age. This is already happening in China. But as a nation, it will be able to position itself extremely well technologically and economically, and this is a reality the rest of the world needs to be prepared to deal with.
You'd be amazed at how resistant most people are to anything that feels unfamiliar, even if it's good for them. Coal and oil jobs are familiar, green jobs are not.
It should be as simple as you're suggesting, but sadly it isn't.
