React rarely breaks your code, and if it does, you must've been doing something peculiar. Then, chances are that the problem is well-isolated and relatively simple to fix.
Most companies don't care about diversity of any kind for any reason besides PR. Every hiring manager knows that the most productive engineering teams are made up of 100% Asian cis-male Libertarians.
Diversity in terms of measurable metrics, such as women/minorities/LGBT++ being adequately represented, is simply a benchmark that can be paraded around for appeasement purposes.
The curve flattens naturally at some point, always after “something” has been done. That does not mean these two things are related to any significant degree.
Why? There's a lot of stuff getting developed with web technology as the platform of choice. Not because developers want to, but because major stakeholders are pushing for it. It enables cross-device deployment without gatekeeping by platform holders and crusty IT departments. Making the platform worse just makes these applications worse, it won't turn them into pristine native applications.
If you take 10,000IU because 8895IU is what gets 97.5% of people to 50nmol/L, you are basically assuming you need more supplement than 97.5% of people, which is highly unlikely. There are people "at risk" that have trouble metabolizing the supplement, but chances are you're not one of them.
You need to do blood tests. Don't take 10,000IU daily without consulting a doctor. The "generally considered safe" upper limit is 4000IU. You'll probably be fine with 2000IU. Too much Vitamin D can mess with your calcium and doses as low as 5000IU/daily over a few years have been reported to cause serious problems.
Safari may be fast, especially on mobile, but it sure is holding back everyone on features. The irony is that with WebGL2 and WASM, near-native-speed applications would be possible.
Also, if there were Safari APIs for all their fancy chip features, developers might actually use them widely.
The problem is that if this happened, Apple would lose its monopoly on a good app experience. They need web technology to be crappy, and poor performance is part of that picture.
Game engines are usually maintained for years if not decades, as they are often enormous investments. However, it's more common to fork (or at least freeze) for a specific project, so in that sense there is more room for ad-hoc solutions.
I didn't mean to say that there isn't any race-specific research, but that there is a risk of being called a racist (or a "race realist") associated with doing such research, especially when it gets attention from sensationalist media and keyboard warriors on social media.
Therefore, if there is such a risk, it must have a chilling effect on actual research and on public health relations, even if doesn't outright prevent it from happening at all.
You are demonstrating that there indeed is such a risk, by suggesting that I'm one step away from proclaiming the superiority of the white race. You're not doing anyone any favors with that.
The difference is that it's a shift in perspective. It's acceptable to say that white people aren't suited to live in Australia. It's not acceptable to say that black people aren't suited to live in the UK, for example.
You're being uncharitable, which is part of the problem. These supplements are "recently invented" in terms of evolutionary history and it's not clear how well they work, compared to actual sun exposure.
"Not suited to" may be a contentious choice of words, but "not adapted to" is plain fact. Not being adapted to an environment confers disadvantages. Perhaps these disadvantages are minor, certainly in this case they are not lethal (in isolation), but from a healthcare perspective, they are important to take into consideration.
Consider that jumping at every opportunity to scold someone choosing their words unwisely does nothing to actually fight racism, but could indirectly harm those people you are intending to help. After all, why would a true racist care about the health outcomes of the races they ostensibly despise? Why would anyone risk investigating genetic differences in medicine, when the payoff is an accusation of racism by well-meaning but uneducated laymen?
In any event, the really ugly part is matching, not construction or assignment.
