  • I think the problem is the farmers would be happy to know IT if it meant they could fix their damn tractor. Deere doesn’t want them to know IT, it wants them to just call their local Deere service center anytime anything doesn’t work. Problem is, if it’s during a harvest or some other critical time, they can’t wait a week for a service appointment so they have to pay through the nose for immediate call out. And much of the time, the problem is something that they are easily capable to fix on their own, but can’t because they don’t have access to the service software that only dealers get. Or it’s a situation like iPhones where they can easily make the repair but need the software to authorize the repair.

    The result was a lot of farmers installing hacked Ukrainian firmware on their tractors, simply because the hacked version would accept any part connected and not require authorization from a service laptop.

    Well that’s shooting yourself in the damn foot.

    Apple users are a tiny percentage, and most of the sort that happily uses whatever Apple gives them without question or concern for other options. I have no idea what this thing did, but if it did something different than every other browser should start targeting Windows and Linux.


  • Yes I am, and that is exactly the point. I do not want spinning disks in my desktop, or anyone’s desktop or laptop. Give the actual computer a fast SSD for the OS and programs, then store the big data on a NAS or server. How’s the computer access it from that server in real time.
    At 100 megabits (10 megabytes per second) that isn’t very fun. Gigabit ethernet is 100 megabytes per second give or take. That is where it starts to become useful for storage, as most spinning disks themselves have a transfer rate between 100 and 150 megabytes per second.

    But as you just pointed out, that can become a bottleneck. Especially if you have multiple people accessing the server. How much of a problem it becomes depends on what they’re doing. IE, 10 people editing photos can happily share a gigabit link to the server because they load the photo once and then the link sits idle while they work as the photo is cached in RAM, 10 people editing uncompressed high definition video will probably want a constant full gigabit to each of them because they’ll be using almost all of it constantly so you need a gigabit to each desk and 10 gig to the server (and a storage array with sufficient bandwidth)




  • About damn time. We got a boost every few years from 10 to 100 to 1000. Then we just… Stopped. Stagnated. It’s understandable why, for a good long time one gigabit was all anybody needed, 100 MByte/sec is pretty good even for a NAS.

    Of course then fiber ISPs got in the game, now in a lot of places you can buy 7-8gbps as a consumer product. And even multi-gig, which was supposed to ‘fix’ this, really ended up being insufficient. You could make a salad argument that multi gig was a waste of time and we should have just started moving to 10 gig.

    Unfortunately, 10 gig switches still carry a significant premium. But this will start to shake that up. Sooner the better.



  • For anyone not familiar with thorium…

    Thorium is a great nuclear fuel. Much much safer than the uranium we currently use, because the reaction works best only within a narrow temperature band. Unlike uranium which can run away, a thorium reactor would become less efficient as it overheats possibly preventing a huge problem. That means the fuel must be melted into liquid to achieve the right temperature. That also provides a safety mechanism, you simply put a melt plug in the bottom of the reactor so if the reactor overheats the plug melts and all the fuel pours out into some safe containment system. This makes a Chernobyl / Fukushima style meltdown essentially impossible.

    There are other benefits to this. The molten fuel can contain other elements as well, meaning a thorium reactor can actually consume nuclear waste from a uranium reactor as part of its fuel mix. The resulting waste from a thorium reactor is radioactive for dozens or hundreds of years not tens of thousands of years so you don’t need a giant Yucca Mountain style disposal site.
    And thorium is easy to find. Currently it is an undesirable waste product of mining other things, we have enough of it in waste piles to run our whole civilization for like 100 years. And there’s plenty more to dig up.

    There are challenges though. The molten uranium is usually contained in a molten salt solution, which is corrosive. This creates issues for pipes, pumps, valves, etc. The fuel also needs frequent reprocessing, meaning a truly viable thorium plant would most likely have a fuel processing facility as part of the plant.

    The problems however are not unsolvable, Even with current technology. We actually had some research reactors running on thorium in the mid-1900s but uranium got the official endorsement, perhaps because you can’t use a thorium reactor to build bombs. So we basically abandoned the technology.

    China has been heavily investing in thorium for a while. This appears to be one of the results of that investment. Now this is a tiny baby reactor, basically a lab toy, a proof of concept. Don’t expect this to power anybody’s house. The point is though, it works. You have a 2 megawatt working reactor today, next you build a 20 megawatt demonstrator, then you start building out 200 megawatt units to attach to the power grid.

    Obviously I have no crystal ball. But if this technology works, this is the start of something very big. I am sure China will continue developing this tech full throttle. If they make it work at scale, China becomes the first country in the world that essentially has unlimited energy. And then the rest of the world is buying their thorium reactors from China.
