> but Musk still needs to send it out of orbit without explosions, so here's hoping
The Falcon Heavy has made 12 launches and all of them have been successful. It's built using the same engines as the Falcon 9, which has become the boringly reliable workhorse of space launch, and the rocket cores are very similar in design. I'd bet on a successful launch, and probably on a successful landing of the side boosters.

There are school shootings and they’re certainly awful. Similarly, people sometimes get struck by lightning, and this is awful too. But if your goal is to prevent deaths, rather than to focus on the things that make for the most lurid news stories, then there are boring things like road safety that loom much larger in the numbers than they do in the public imagination. Here are some numbers on causes of death for children and adolescents in the US, reported by the CDC:
Figures for deaths from school shootings are harder to come by, since it seems like all the sources are trying to push some political narrative or other, but the highest numbers I could find were in the low double digits per year (on average). Preventing those doesn’t strike me as a high-priority use of limited death-prevention resources.
From your own link, there are 12,000 injury related deaths. Of those, over 1/3 are firearms related and 1/3 of those are homicides. They may not be school shootings, but damn does that seem related to the second word.
Anyway, to answer your question: because we already do a lot to stop the other causes. Cars have oodles of safety regulations, for instance. Home pools have rules on covers in many states, lifeguards are placed at water features. But we can't just snap our fingers and stop all car deaths, or cure all disease.
Meanwhile shooting deaths are an entirely artificial problem, which we actively do less than nothing to solve. Both by avoiding root cause fixes - not only avoiding addressing mental health, but actively encouraging bullying of minorities like trans students - but also avoiding regulation of the most effective tools (guns).
And, just a final point, humans are human. A kid dying in a tragic accident or disease is heartbreaking. But a dozen kids being eviscerated on Live TV repeatedly for someone's entire adult life, with tens of millions of people having the audacity to say "get over it, we refuse to talk about this" or "even "it's a hoax"? That's enraging.
We are emotional animals, but I'm more than happy that we try to leverage our empathy to make the world a better place. We can do more than one thing at a time, after all. For instance, under your argument, nobody should have bothered inventing amber alerts because it doesn't save hundreds of kids per year.
They're going for an orbital height of 600–800 km, or about 2-3 light-milliseconds from Earth's surface. A lot of people think of satellites as being necessarily high-latency because of intuition drawn from satellites in geosynchronous orbit – but those are about 50x farther away from earth and have correspondingly longer ping times.
They don't go directly to the satellite but through ground stations and then bounce around on lasers between satellites. The latency is going to be worse than fiber
From Google's spokesperson, quoted in the article: "This is a short-term, timely agreement to ensure we have bridge capacity to meet surging customer demand for our agent platform, Gemini Enterprise, which has been even higher than we expected."
Google wants a lot of compute sooner rather than later, and they're willing to pay a premium for speedy delivery of that compute. SpaceX has the capacity already built and ready to go. Hence the high price.
Musk made big investments in building AI data centers starting in 2024, continuing through the present. SpaceX got those assets from xAI, spun off from X, via an acquisition. More details:
Even then, the numbers don't even remotely work out. Consider this "Elon Bezos" person; the combined net worth of Elon Musk and Jeff Bezos is about $1.3 trillion or so, and the "Top 0.1%" category in the Fed's data has a net worth of about $25 trillion. This is not a small difference.
You're right, of course, but "those in government" aren't a single entity. There's always an incentive for one corrupt part of government to take more than their fair share of the loot, and then for the next part to take more, and so on... until their combined cut is over the revenue-maximizing percentage, and they make less than they could have if they had coordinated better.
(I want to call this "the tragedy of the commons," but that phrase doesn't sound quite dark enough.)
its usually those with financial interests and objectives simply corrupt politicians to legislate their way into reality. politicians serve the highest bidder
It doesn't track cost of living? The way it's calculated is all about cost of living!
In the US, the official inflation numbers are based on a "basket of goods" meant to be representative of a typical person's spending. Housing currently makes up about a third of the basket, while luxury items are a fairly small percentage. Here's a pretty well-written summary, albeit with numbers from 2022:
Changes in housing prices have a large effect on the BLS's inflation figures. Downward changes in the price of luxury goods have a small (and bounded) effect. Even if all luxury goods became free, the reduction in inflation wouldn't be all that much.
CPI is an aggregate measure which munges a bunch of things together under a single statistic.
In fact, the cost of necessities has overall risen faster than the cost of discretionary goods. This has been generally true since the mid-1990s; prior to that, inflation differences were much smaller across income groups despite lower income groups spending more of their income on necessities. In some periods like the post-COVID housing and energy price shocks, the differential effect of real inflation on basic necessities has been even greater.
Even "small" effects compound over time. For example, when someone in a low bracket loses 10% purchasing power after many years, the net economic stress they experience is much greater than for someone at a high bracket. Differential inflation of necessities vs discretionary goods magnifies this.
Housing is actually ~44% in 2024, but the subcategory of 'Shelter' is ~35% for CPI-U. 'Shelter' is further broken down into rent and owner's equivalent of rent. 'Owners' equivalent rent of residences' is ~26% for CPI-U and ~21% for CPI-W, 'Rent of primary residence' is around 7% and 10% respectively.
Depending on how one live their lifestyle, the 'inflation' calculation can greatly vary in relevance.
Nope. CPI is an excellent differential indicator -- "how much did a typical person's cost of living rise this year" -- but it's a terrible integral indicator if you compound it because it's blind to the difference between forced and voluntary substitution. If essentials inflate faster than wages, money_in=money_out drives a reduction in nonessentials -- forced substitution -- and the CPI basket adjustments launder the forced substitution into voluntary substitution.
Well, "launder" is a strong word that the hardworking bureaucrats at BLS do not deserve, but the people who use CPI as a deflater so that they can wave around graphs "proving" that things have never been better absolutely deserve it, so I'll keep it in.
Bonus meme: the American Dream was not to Owner Imputed Rent a house.
Yes, it also takes into account rising quality. For an example, in 2010 I rented a rat hole apartment for $x from a fisherman who had inherited the building. He never did maintenance (he was out to sea most of the year) and he never raised rent.
A large company bought the building after I moved out. Ten years later, the same apartment with a fresh coat of paint and new countertops was back on the market for a rent of about three times $x.
The CPI can say that apartment, since it was refurbished, increased in quality and so it wasn't really a price increase of the same good from $x to $3x. This offers a "degree of freedom" to adjust the CPI itself (since quality is inherently subjective), and may be a big part of why CPI does not reflect the lived experience.
I didn't care one bit about paint or countertops when I rented that apartment and I assume broke young adults today don't either. At the time I wanted the cheapest place to live in the area and this was it. It still is one of the cheapest places, but you need three times as much money to rent it.
The wording was a bit unclear. The previous paragraph mentions wanting something cheaper than "those pesky XORs and multiplications". The multiplication is the expensive part; the (very cheap) XORs are just mildly annoying because you have to think about what they're doing.
> I’d like to know the memory profile of this. The bottleneck is obviously sort which buffers everything in memory.
That's not obvious to me. I checked the manuals for sort(1) in GNU and FreeBSD, and neither of them buffer everything in memory by default. Instead they read chunks to an in-memory buffer, sort each chunk, and (if there are multiple chunks) use the filesystem as temporary storage for an external mergesort.
This sorting program was originally developed with memory-starved computers in mind, and the legacy shows.
