    I had a Welsh work colleague years ago. A few times he was on the phone and spoke Welsh. None of the mental markers on what language he was speaking seemed to change. It sounded like English, spoken with a Welsh accent. Until my brain tried to interpret it. It was like I had had a stroke. It parsed as English, but wouldn’t make sense. It took a conscious effort to remind myself that he wasn’t speaking English.

    In basic terms. Humans have a hibernation instinct, from somewhere in our past. When the days start to get short, and we get less sunlight, our brain tries to kick this in. It makes us want to be lethargic and sleep a lot. Unfortunately, modern life isn’t conducive to this. When you push past it, the effects are very similar to depression.

    Different people are affected to different degrees. Some are downright miserable, others unaffected. It’s also possible to treat it. Sun lamps can trick the brain into thinking it’s not winter, as vitamin D. The effectiveness of this can vary, however, and it doesn’t compete with the real sun jumpstarting your brain back to full functionality.

    LLMs can’t become AGIs. They have no ability to actually reason. What they can do is use predigested reasoning to fake it. It’s particularly obvious with certain classes of proble., when they fall down. I think the fact it fakes so well tells us more about human intelligence than AI.

    That being said, LLMs will likely be a critical part of a future AGI. Right now, they are a lobotomised speech centre. Different groups are already starting to tie them to other forms of AI. If we can crack building a reasoning engine, then a full AGI is possible. An LLM might even form its internal communication method, akin to our internal monologue.

    The dream router is an excellent base to build upon. It provides all the normal functions (ethernet, wifi, router etc) as well as hosting the control software.

    Unifi’s real power is when you expand it. The access points make extending WiFi coverage easy. You dont even need a wired link. It will link over WiFi, either as a primary or as a fall back. The flex mini is also quite handy. It’s a little poe powered switch. I have a couple tucked away providing extra ports around the house.

    With my setup, I have detailed monitoring and control down to the port or wifi device. I can monitor and control things in detail, or get a high level view of my network.


  • While expensive, UniFi hardware is just a huge step beyond the rest of the consumer market.

    I’ve had literally 10x the range (5x vs 50m), in congested environments, compared to ‘gaming’ hardware. I actually did a side by side to test. I was shocked at the difference.

    The bridging function is also a life saver. 2 LR units can get a reliable signal between each other, at ridiculous ranges.









  • If your pads are lifting, you’re overheating the board.

    A couple of tips that can help a lot.

    Don’t underestimate the importance of flux. Cheap boards often have a lot of crap on the copper. Flux burns this off, allowing for quicker, better joints. Most solders have flux in them, some more than others. Beyond that, you can also buy rosin flux very cheaply. It’s amazing for cleaning up particularly bad, or sensitive, components.

    Have confidence when heating. Most newbies tend to ‘dab’. They are scared to overheat the component or board, and so try to add a little heat at a time. This is actually FAR worse for heat. The heat spreads out into the components and glue, causing problems. Instead, you apply heat once. The iron stays in place until the joint forms. If you back off, you need to wait a few minutes until everything is completely cool to the touch. No tap-tap-taping.

    The last point of note is to check your lighting. Most beginners struggle to actually see what they are doing. In low light, our pupils open up, to allow more in. This reduces our depth of field, and makes it harder to focus clearly. You want daylight levels of light on your workpiece. There are several apps that let you measure light levels. You might be shocked at how low it is. Multiple directional lights are the best option. You want it focused to maximise brightness, but multi source to avoid harsh shadows.

    You might have figured out most of these, but hopefully, some of it will be of help.




  • That wouldn’t work. You would need to change the orbital sizes, bonding forces (EM strong and weak, at least), and flow of time exactly in lockstep. Any deviation would show up in quantum mechanical experiments. None of these appear to have simple relationships to each other. It would be a huge new lump of physics to allow this to happen.

    The more likely explanation is that space has a very slight tendency to expand. It would need intergalactic (not just interstellar) distances to be detectable. We also know that (very strongly suspect) that space expanded rapidly in the very early universe. Space then collapsed into a cooler, more stable state. It was initially thought the expansion tapered off to zero, but it might be slightly positive still.
