Comment Re:do they have the USB logo on the system? (Score 2) 45

My suspicion is that they are probably in the clear. the USB PD spec includes 'vendor-defined messages'; both 'structured VDMs' that are standardized and 'unstructured VDMs' that are basically whatever the implementer feels like. This obviously doesn't prove that Nintendo are in full compliance with what the USB-IF really wants the USB trademarks applied to; but(along with the reports that it plays just fine with 3rd party chargers) it looks a lot more like a basically-compliant-minus-any-bugs-or-compatibility-hacks USB PD implementation that just doesn't mention DP alt mode unless it likes the unstructured VDM chatter. Dick move; but one you could do in full standards compliance.

Sounds like they are acting all pious over what is basically a workplace dispute over division of margins.

The outfits that do ransomware negotiations remain legal; because for some reason that's one area where nobody bats an eye at you doing business with transnational criminal syndicates; but they are basically just bagmen who take a cut of the deal for interacting with the disreputable ransomware guys for you. In this case, apparently one of the employees wanted a larger percentage of the cut than he was getting from his employer.

I suspect that what he did is some sort of crime in a way that what his employer does isn't; but it's the same business model; just with some disagreement over whether that guy gets a percentage directly as well or whether just the company does.

Sure, itâ(TM)s quite possible for two people to exchange offhand remarks about the local weather apropos of nothing, with no broader point in mind. It happens all the time, even, I suppose, right in the middle of a discussion of the impact of climate change on the very parameters they were discussing.

The thing to understand is we're talking about sixth tenths of a degree warming since 1990, when averaged over *the entire globe* for the *entire year*. If the change were actually distributed that way -- evenly everywhere over the whole year -- nobody would notice any change whatsoever; there would be no natural system disruption. The temperature rise would be nearly impossible to detect against the natural background variation.

That's the thinking of people who point out that the weather outside their doors is unusually cool despite global warming. And if that was what climate change models actually predicted, they'd be right. But that's not what the models predict. They predict a patchwork of some places experiencing unusual heat while others experience unusual coolness, a patchwork that is constantly shifting over time. Only when you do the massive statistical work of averaging *everywhere, all the time* out over the course of the year does it manifest unambiguously as "warming".

In the short term -- over the course of the coming decade for example, -- it's less misleading to think of the troposphere becoming more *energetic*. When you consider six tenths of a degree increase across the roughly 10^18 kg of the troposphere, that is as vast, almost unthinkable amount of energy increase. Note that this also accompanied by a *cooling* of the stratosphere. Together these produce a a series of extreme weather events, both extreme heat *and* extreme cold, that aggregated into an average increase that's meaningless as a predictor of what any location experiences at any point in time.

ED: Looks like it's 24(!) hives per beehome, and they charge $2k delivery ($83/hive) plus $400/mo ($400/hive/yr) for maintenance.

Clearly not something of use to amateurs, and I'm not sure whether you can make that economics work out for professionals, either. I guess it depends on how truly independent it is, vs. your local labour costs.

There is little correlation between "presence or absence of pollution" (what a general term to begin with...) and CCD. There is a strong correlation with the presence / absence of varroa. And this system treats varroa.

I've been thinking about getting into beekeeping (I first need to increase the accessibility of my ravine where they'd be), and had been thinking about a sort of high tech solution, with electric blankets, heat-exchanging baffles, a flow hive, and maybe some mass and/or noise sensors for monitoring colony health. But this is WAY more high-tech than I envisioned, and honestly I'm scared to even look up the price ;)

Eberhart seems like he may be falling for the hype himself. He says "What's happening now isn't innovation; it's aspiration masquerading as disruption..."; but fails to note the fairly profound differences in results between the orbital delivery guys and the moonshot guys; and how neatly that maps onto what is aspiration and what isn't.

Putting satellites into orbit is kind of mundane at this point, too common, too obviously useful; but it's sufficiently obviously useful that more or less anyone with nation-state aspirations wants to at least have a program that executes; and civilian and day-to-day operations want someone who executes but cheaper. And that exists. Going to the moon is cool, and it's a nice prestige project for when the gerontocracy needs to show that they still have it just like when they showed the commies what for; but it's unclear exactly what the point is or the stakes are beyond that. The customer presumably would like to actually land something on the moon, at some point, just to say that they did; but what they are buying is mostly aspiration on the cheap: We get to say that we have a lunar program for way less than Apollo money, you do some open-ended tinkering, honor satisfied.

He can talk about 'accountability'; but it seems like it's a fundamentally hard problem to actually sustain a lie about how serious you are, at an institutional level, in the long term. It's not like do-or-die projects are free of losers(especially because circumstances have a nasty habit of thrusting them on people whether they like it or not; rather than giving them the luxury of choosing whether or not to take on those stakes); but they tend to be animated by a sense of genuine urgency. Stuff that is, fundamentally, kind of optional, by contrast, tends to reflect that in bulk. Timmy Rockets may be genuinely more passionate about stir-welding than you've ever been about anything; but, like is cousin who is really passionate social worker, will soon discover that going to the moon and fighting poverty are open-ended projects we do because they sound nice, not because anyone who matters is actually committing to a deadline.

Leaders aren't there out there e.g. building the rockets or doing the vast majority of the engineering. Musk doesn't get credit for that. But they do set the culture and direction for their companies. And in this regard, the "build quickly, launch quickly, fail quickly, learn quickly, and iterate quickly" culture developed for SpaceX happens to be very effective. Musk gets credit for instilling that. Another thing he should get credit for is the broad design strokes such as "focus on designs that are cheap enough that they can be mass produced, gaining you economies of scale and the ability to iterate quickly during testing, but are still capable of being reused" (this differs from the two previous predominant paradigms, either super-expensive low-volume reusables, or cheap high-volume disposables).

I don't like the guy, but absolutely, credit where it's due.

Comment Re:Erm... (Score 5, Interesting) 159

I think a lot of people miss the fact that SpaceX engineers know very well that what they're doing might fail spectacularly, and that this is the cost of speed.

A random example: autogenous pressurization.

It's beneficial to have a rocket's engines pressurize the tanks themselves rather than to haul up pressurant tanks and a separate pressurant. But it's surprisingly tricky. For a methalox rocket, you ideally want hot methane injected into the methane tank, and hot oxygen into the oxygen tank. But hot oxygen is very difficult to work with in an engine, as it tends to eat your engine.

If you're still working on reliably producing hot oxygen, there is a hack available to you, but it's not pretty: just inject exhaust into the oxygen tank; after all, it's not combustible. BUT, it is water and carbon dioxide. Both can settle out as frosts or plated ices, and in the liquid, the water ice will float at the top, while the CO2 will form a snow at the bottom. Frosts / ice plating can block e.g. your RCS jets. The CO2 snow will kill your engines. You can put in filters around their intakes, but it'll clog your filters. You might try expanding the filters, and maybe that'll work for a while, but then you rotate the rocket, the snow rushes ti one side, and a bunch of engines die from clogging. You may put some big mesh plates across the whole tank to keep the snow off the bottom, but they can cause their own problems with fluid flow and still sometimes clog or let snow through during maneuvers. Etc.

So then comes the question: put Starship on hold while working on getting the engines to reliably produce hot oxygen, potentially for years, or forge ahead with a hack solution that you know has a reasonable chance of killing your rocket?

To SpaceX, the question is obvious. You cannot afford to give up years of critical flight data just to avoid some booms. The decision is immensely lopsided in favour of "put in the hack solutions and launch, while you work on the proper solutions". Because you learn SO much from every launch that can be used to evolve your design. And you also learn so much from every rocket that you build, whether you launch it or not, so you might as well launch it.

To be clear, you don't want to lose rockets due to doing stupid things. Like, for example, if it turns out that some SpaceX engineer installed the wrong COPV and caused the recent pad explosion**, basically the only thing they would learn from that is "have tighter controls on your COPV processes", which isn't at all worth the cost of the explosion. But in general, if you launch and it clears the pad, you're getting good, important data from it, it's worth it even if it blows up seconds later, and it's on to the next evolved version of the rocket in your production sequence with both production- and flight lessons learned.

** It's clear that the recent explosion was from a COPV failure, but it's unclear why. Some claimed leaks state that a COPV may have been coded to a higher pressure than it actually was during production, so when they scanned it it checked out as being the right tank, but actually was not designed to handle the needed pressures. But I'll wait for official confirmation on this. SpaceX only makes some of their COPVs, usually not the smaller ones - ones that have washed up ashore were made by Luxfer. So this could be a supplier problem, like the strut failure on a 2015 Falcon flight. But again, too early to say.

"What am I missing?"

That the author of this article is an idiot.

Yes, humans went to the moon in the 1960s. It also consumed a huge chunk of the federal budget. Adjusting for inflation by NASA's NNSI inflation index, the entire Lunar program cost $288,1B. If the US were to prioritize a project to the same degree today as then, accounting for GDP growth in inflation-adjusted terms, it would be $702,3B. NASA's annual budget is around $25B.

The cost of access to space today is a tiny fraction of what it used to be, when accounting for inflation. And keeps pushing lower. No, it's not "easy", but it absolutely is being done.
