  • It would work fine in a vacuum, e.g. on the moon. Unfortunately, on earth we have a thick atmosphere to deal with. Orbits are about going sideways VERY fast. If you try and plough through the atmosphere at 7km/second it creates a LOT of heat, and uses a LOT of energy. You also can’t just lob a satellite up. It will need to circularise its orbit, so you need to log an engine and fuel too.

    Basically, it’s viable as a technological idea, but not on earth.


  • Provisio, I have not read up on this particular experience.

    Fruit flies, as used in labs are not like their wild cousins. They have been bred to be exceptionally consistent, since this makes X-Y experiments easier. If you take genetically identical eggs, and raise them in effectively identical conditions, you get almost the same wiring.

    There will still be areas of variability, but a lot will be conserved. This is likely an “average” wiring. Once you have even an approximate baseline, you can vary things and see how the wiring adapted.




  • The key to steam is that they realised that being user centric, while bad for short term profits is very good for long term profits. They are also not publicly traded, so not just anyone can buy in and try and make a quick buck burning them to the ground.

    I’ve found their store and setup to be a reasonable balance of advertising to functionality. The fact that you can adjust it yourself is a good example of their mindset. Most people don’t care or find them useful. Those who don’t like them are unlikely to interact with them, so it’s not worth fighting their efforts to turn them off.





  • It’s a balancing act. Push it too hard, and the dream collapses. Don’t push enough, and you relax back into true sleep again.

    Try and tweak 1 thing at a time. You’ll also need to roll with the narrative. It’s like improv, saying no is dangerous, it can leave the other party with nowhere to go. Always agree with their premise, bit add your own spin to it.

    As for techniques, I’ve found dream checks to be most effective. You need to do it regularly, while away. This will make you also do it in a dream. Mine is to check my back pocket for “hammerspace” type capabilities. I will never have an AK47, or a giant mallet in my back pocket. When I pull one out, I know I’m dreaming. It also makes nightmares a non issue.


  • I had good luck with these at my wedding. Instead of disposable cameras, I put cheap digital cameras. It didn’t take long for guests to realise that the pictures were appearing on a large tv, in a sideshow. People got a lot more creative when they realised they would be seen quickly, not weeks later.

    I managed to get them working without proprietary software, too. The onboard script logged into WiFi and uploaded the photos over ftp.

    Given their size and the level of tech at the time, it was pretty impressive.

    Your best bet might be to use a laptop as the basis. They are already designed with power efficiency in mind, and you won’t need an external screen and keyboard for local problem solving.

    I would also consider having a raspberry pi 3 or similar as a companion. Services that must be up all the time run on the pi (e.g. network admin). The main computer only gets kicked out of sleep mode when required. The pi 3 needs less power than the newer pis, while still having enough computing power to not lag unless pushed hard.

    I definitely agree with SSDs. HDDs don’t do well when rotated when running. Boats are less than a stable platform.



  • One of Sir Issac Newton’s famous phrases is

    “If I have seen further it is by standing on the shoulders of Giants”

    This sounds very nobal and humbling. However, its meaning totally changes with a few facts. It was written in an open letter to Robert Hooke. Hooke was apparently quite short, and EXTREMELY sensitive about this. Newton was basically dissing Hooke. Nobody will be standing on your shoulders, shortie!
