  1. I know Laplink still sells transfer cables, they have a USB 3.0 version for $50. https://web.laplink.com/cables...

    At that price I'd be better off buying a couple USB to Ethernet adapters and an Ethernet cable. That would be faster, possibly cheaper, not require any drivers (or at least none not easily obtained), and still offer the ability to breakup this "home brew Laplink" to connect a couple computers to an Ethernet network.

    By looking hard enough I was able to find someone selling a passive, and USB 3.0 compliant, USB-A to USB-A cable for about $15. https://www.datapro.net/produc...

    The warning on the DataPro webpage indicates that this cable will not support networking or file transfer with Windows, macOS, or Linux. Well, why not? Clearly this is supported in the USB spec and Microsoft provides debugging on this cable with some registry editing. Apple seemed to figure out how to write the software needed for networking on a passive cable for Thunderbolt, Firewire, Ethernet, and going all the way back to serial ports with LocalTalk. Seems to me that they are more than halfway there with the hardware and software, they need only to take those last few steps to take this from the realm of superusers to the everyday.

    I can understand why Apple doesn't support direct USB to USB networking. First, they support higher speeds on other ports. Second, there's a lot of non-compliant USB cables floating about and they likely don't want to be held responsible for someone burning up their laptop over this. Third, without support from other manufacturers and OS publishers there's no real market for it.

    Let's ignore the USB-A to USB-A aspect of this for a moment. I should be able to connect a couple computers together with a USB-A to USB-C cable, or USB-C to USB-C cable, and do more than charge up a laptop battery. There is a data connection there, all we need is the software to transfer some data. Given that Ethernet ports are disappearing from computers, and USB-C is taking their place, one would think that a computer manufacturer would want to assure that the ability to make a fast and direct connection to another computer was maintained. Well, I mean, besides just Apple.

To stop burning it for electricity they need something to replace it. They may be building lots of solar but they are also building nuclear. It seems they plan to build far more nuclear than solar.

  3. No wired network is a killer in some settings.

    I agree. What bothers me is the increasing lack of Ethernet ports and no support for an inexpensive alternative. All it would take is the small step of support for USB to USB networking with a passive cable. This was written in the USB spec 10 years ago, but it seems few people bothered to implement it. It's in section 5.5.2 of the USB 3.0 whitepaper.

    https://www.usb3.com/whitepape...

    Apple doesn't have this problem because they have USB-C ports on all new computers and support networking over a passive cable by use of the Thunderbolt protocol. An inexpensive passive cable will connect two Apple computers at 10 Gbps. A wired network does not necessarily mean Ethernet.

    I guess if Apple supported this kind of connection with USB 3.0 it might go just as fast, and be able to connect to any computer with a USB-A port with a widely available an inexpensive USB-A to USB-C cable, but then the other computer would have to support this as well. There's little incentive by Apple to support this if Windows and Linux can't be bothered to support a direct PC to PC connection by USB.

    Oh, and if you really needed to have Ethernet to connect by a wire to another computer then there's all kinds of adapters out there for this. Given the increasing scarcity of Ethernet ports on new Windows computers, especially laptops and tablets, the need for such an adapter is shared with Apples. But, again, I can connect two new Apple computers together at 10 Gbps with a $10 cable I can get at most any Best Buy, Wal-Mart, or whatever. I can't do this with Windows or Linux, or at least I haven't seen it yet.

    I'd like to be able to do the same with Windows and Linux. Why after 10 years has no one bothered to read the USB spec and implement a very useful wired connection between PCs? Seems to me that there would be no hardware limitation for this, all we need is the software. Has no third party read this either and seen the possibilities?

    Medical research should be entirely funded by the public, and all patents and treatments that result made available to the public for free.

    So, you'd ban any privately funded medical research then? That doesn't sound like a society I'd want to live in. In that case the government has a monopoly on medical research and if you had some disease that the government didn't feel like researching then you won't get treated. If you had piles of money that you'd be willing to spend on a cure for your own disease, or donate to someone with a similar goal of finding a cure, then the government would bar you from doing so.

    I'm pretty sure that the best path is a combination of both. We can have our publicly funded research without barring private research. And private research does not need to come at the expense of public research. Each has their merits.

    We saw a lot of research in prosthetic limbs come from public research as wars lead to soldiers coming back as amputees. The government has a high motivation on taking care of those that defended the nation after they've fought. This research can become available publicly for use to treat birth defects and industrial accidents, both of which are quite rare in modern society and not very profitable for private investment. Once the research is done though the actual manufacturing of these devices may in fact be very profitable.

    Private research on profitable cosmetic surgery tends to also help out on less profitable treatments for birth defects, war injuries, and accidents. What has made elective vision correction surgery so inexpensive has been the government largely staying out of it. Competition between different kinds of such surgeries, and inexpensive corrective lenses, means the surgery had to become very inexpensive or no body would bother.

    No, medical research should not be exclusively publicly funded. Doing this requires the belief that the government knows best always, and they don't. It also requires a government so large that it is capable of barring any private research. As I recall there seems to be a lot of people that exclaim "my body, my choice" when it comes to government intervention in medicine. Well, what happens when people truly get choice? They can fund any medical research they like.

    I know "my body, my choice" is a politically loaded phrase. If the people that shout this from the rooftops actually believed this then they'd keep government funding from medicine as much as they could. When the government pays then they choose. If you want choice then you must pay for it yourself.

The moon can also be a place from which observations of the universe, or of Earth, that might be difficult on Earth's surface or near Earth orbit.

    As I recall from something I read a long time ago the minimum size of a breeding population to avoid inbreeding problems is about 10,000. To assure this is truly self perpetuating then the population would have to be far larger, and likely selected against many inheritable diseases.

    There are, and have been, populations like this on Earth. As one might imagine this turned out well in some cases and not so well in others. Part of this is social pressures on who is an acceptable breeding partner. If cousin marriage is considered accepted, even though far better mates exist, this can result in a drop of IQ, physical deformities, and all kinds of bad things for the future of the population.

    There's cases where a choice for traits that turned out to be a bad idea for the future of the population. I can't recall any examples in human population but in animals there was a deer population that went extinct because a large rack of horns was seen as attractive. This lead to the males growing horns so large that they'd break their own necks. They'd also be encumbered by tree branches and too weighed down to outrun or fight off predators. There's a cattle mutation that doubles muscle size, which might seem like an advantage, but this makes the tongue so large that it can make breathing difficult. Would humans in a small lunar colony be smart enough to avoid this? Not if they end up marrying their cousins for a few generations, I'm guessing.

    Of course it could all turn out well, and everyone lives happily ever after. The colony grows to potentially millions of happy and healthy humans, then they move on to repopulate Earth (assuming time heals all wounds even on a planet killing scale) and go on to colonize the other planets in the solar system.

Maybe a 6 year plan to fit that of a US senator. Maybe an 8 year plan like JFK did in 1962 to send a man to the moon and bring him back safely. That would fit in the two terms that a POTUS could serve.

    That and the SCRAM rods where tipped with graphite as a lubricant. When they hit the SCRAM too late the graphite tipped rods was the last straw that broke the camel's back. It induced another "pulse" of neutrons that sent the reactor pile into an overload from which the rate of the falling SCRAM rods could not stop. The water flash boiled into steam, blew the roof off the building, and the rest is history.

    Oh, and the lack of a containment dome didn't help. Most every other reactor built at the time had a heavy concrete dome built to contain a flash boil event like this. Without the dome the radiation was spread all over. Had it been built with a dome then it would have been another TMI or Fukushima, still an expensive mess but deaths would have been in the single digits instead of in the dozens.

    Modern reactors used heavy water as moderator for a very long time. If reaction runs away, water evaporates, and therefore ceases moderating the reaction, which means reaction no longer has slow neutrons to continue the chain reaction.

    That's how some modern reactors manage it. There's still plenty that use light water. I like heavy water reactors for this very simple safety feature but heavy water is very expensive and had not caught on in many nations. What is likely to replace light water reactors in the next generation are those that use molten fuels, as salts or metals. This means that if the reaction gets away from them then the fuel can be quickly dumped into a containment tank away from the moderator. This is kind of the reverse of the heavy water moderation where the moderator is dumped to stop the reaction.

    Maybe heavy water reactors will catch on again. The price of heavy water will have to come down. Heavy water is considered a nuclear weapon proliferation risk though, because of the use of heavy hydrogen to make fusion boosted bombs.

    People of Asian ancestry always did excel in STEM. That does not mean someone from a different "family" cannot excel. The bell curve still applies, there's always going to be someone from some different family that will do far better than someone from an Asian family.

Inflating grades of minorities doesn't help them, it only sets them up for failure in the future. This also applies to racial quotas on university admissions.

    I'm pretty sure that the cost is more important than the energy density. When it comes to electric cars the cost is mostly in the vehicle, there's just a lot of cheap gas cars out there. Used cars are real cheap and there aren't that many used BEVs just yet to bring that cost down. If you want to argue total cost of ownership being lower then, while quite likely true, it requires someone willing and able to do that math. If this is proven true and it gets out to many buyers then that drives up prices on used BEVs, quite likely negating any savings.

    It *is* leaking 400 tons of radionuclide contaminated water into the Pacific ocean everyday.

    That's the mass of the water, tell me how much mass of actual radioisotopes are leaking into the ocean.

    Now, tell me what are the actual isotopes. This is important because different isotopes pose different hazards, and some isotopes pose no hazard at all. Is it uranium? There's naturally uranium in the seawater already, Japan has been experimenting for a very long time on how to "mine" the sea for their uranium needs. Adding a bit more won't hurt anything. It is tritium? Also naturally occurring. Iodine? All the iodine-131 would have decayed into stable xenon by now. Any other radioactive isotope of iodine that would be left by now has a half life of millions of years, is also naturally occurring, and poses no hazard to plant or animal life.

    There are very few isotopes that are created in a fission reactor, just because we can detect them does not mean they are a hazard to anyone. Also, it's the dose that makes the poison. Dumping 400 tons of just about anything into the ocean means nothing since the ocean is so large. This is especially true since we know that a vast majority of the 400 tons is just plain old H2O. Would I drink this water? No, no more than I'd want to drink seawater. Is this water a hazard to the life at sea? Well, I can find out if it is if we know how much of this 400 tons is not H2O and how much is an actually hazardous material.

    Maybe if they didn't make their robots out of sugar they would last longer under the heat.

    Why didn't you give the whole quote? To lie by omission, I assume.

    There is nothing as energy dense, convenient, safe, and inexpensive as hydrocarbons.

    It's this entire list of attributes that makes hydrocarbons difficult to displace in the energy market. Find something with a significantly similar balance of those benefits, and something more, then we can replace hydrocarbons.
