  • Wow. Meet Your Macher

    China’s navy has apparently tested out a hypersonic rail gun — basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds — but during a demonstration of its power, things didn’t go quite as planned.

    As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn’t go up as high as it was supposed to, the test was ultimately declared unsuccessful.

    This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn’t perform as well as it could have.

    This occurred, as Lu’s team found, because the projectile was spinning too fast during its ascent, resulting in an “undesirable tilt.” Gun for Everybody

    Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China’s other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space (NASA had begun building its own astronaut-shooting railgun in the 1990s, but had to abandon it due to lack of dinero.)

    As with many space technologies, there’s the propensity for some messy overlap with military tech. As such, news about the smart bomb rail gun test, which for the record did not make it all the way to space, could well freak out officials stateside.

    Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology’s potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too.

    Despite the big promises of politicos, there are still lots of technical kinks that’ll need to be ironed out before a giant rail gun is ready to shoot humans — or weapons — into space, not least of which the spinning and tilt issues demonstrated by the Naval Engineering University researchers in this test.

    45% overall would be far higher than 125k. You would have 20% tax up to £50k, 40% tax between £50k and £125k, and then 45% tax above £125k. So in order to be taxed 45% overall you would have to earn well over £125k, as a significant portion of your earnings would still be taxed at the lower rates. You don’t start paying the higher rate until you’re earning it, and even then you pay the lower rate for any earnings below the threshold.

    The UK tax system also has a werid position between about £100k and £125k. There is a tax free allowance between 0 and around £12.5k, when you earn over £100k this starts to reduce until £125k where it is entirely removed. After £125k you start making money again, but with earnings of between £100k and £125k per year you can actually take home less.

    There is specific maths that clear this up more consisely (not least because thresholds change every year) but that’s the general gist of it.

    When Reagan was in office I think it was 95% for income over $1,000,000. He claimed that if he was getting taxed 95% for making a movie, he wouldn’t make a movie, and everyone else involved would be out of work. Because sure, they’re not going to just hire another actor instead… Unfortunately idiots believed him.

    Actually the UK’s Higher Tax Rate is 40% for income above £50k, but when you add in National Insurance tax the total rate of tax is 42% (with 28% for earnings between £12k and £50k).

    For incomes over £125k under the Additional Tax Rate it’s 45% (47% with National Insurance. So a significant number of high income workers do get taxed 45% or above, at least for a portion of their salaried/wage income.

    The kicker is that the wealthy don’t earn most of their money working for an income, they do it through investments, which is covered under capital gains tax. Income tax starts at 20% and goes up with income, meanwhile capital gains tax starts at 20% and goes down through loopholes.

    The issue isn’t income tax, that’s just making the plebs fight against one another. The issue is capital gains tax and all the loopholes the ultra wealthy use to avoid paying their share. These people don’t contribute to society, they don’t work, they just make money off of their money and other peoples’ work.













  • Yes, I intentionally gave examples that were open. Some black people take offense to that label, others take offense to “African American”, or whatever. People take offense to all sorts of things. In the words of Stephen Fry, "So fucking what? It’s just a whine.”

    The point isn’t really wether it’s a correct term or not but ignoring the wish to not be called that and instead doing so with the intention to insult.

    The term is not inherently an insult, though. You would have to alter it (eg “cissy”) for it to reasonably be considered an insult by default. Merely objecting to a term that any reasonable person would see as accurate and not an insult is not enough - it would just be a whine. If it was used further after an objection, then maybe intent could be proven, but that’s not what Musk is talking about here. He’s banning the term altogether and saying it is inherently insulting, when it is not.
