    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.










  • That’s also just the electrical portion of our mind. There are whole levels of chemical, and chemical potentials at work. Neurones will fire differently depending on the chemical soup around them. Most of our moods are chemically based. E.g. adrenaline and testosterone making us more aggressive.

    Our mind also extends out of our heads. Organ transplant recipricants have noted personality changes. Food preferences being the most prevailant.

    The neurons only deal with ‘fast’ thinking. ‘slow’ thinking is far more complex and distributed.





  • 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.


  • Most of the problem with lasers come from focusing them. The eye is incredibly good at it. This means even a small laser pen can reach MW/m^2 ranges by the time it hits the retina.

    IR is a different story (at longer wavelengths). Without the ability to see it, our eye will not attempt to focus on it. Also, our eyes lenses are not particularly transparent to it. 3rd, the ultra short pulses mean that there is no time to focus.

    As for the mosquito, the laser is tuned to a frequency that is strongly absorbed by their wings. Given their size and how delicate their wings are, a tiny amount of energy can cause significant damage. Conversely, the same energy on our eye will just cause a slight amount of heating. The bulk mass of the eye will absorb this fine, with no damage



  • I think it’s more the fact that the Russians likely wouldn’t be selling their “good” nukes. They would be selling the old, run-down ones. They would be a large chance they wouldn’t detonate properly.

    There’s also a lot of debate on how well the rest of Russia’s nuclear arsenal has been maintained. It’s highly specialist work that can’t easily be verified by non-specialists. I wouldn’t be surprised if a lot of Russian nukes were already non-viable due to corruption affecting maintenance.



  • I personally support this plan. Smoking in the UK has already plummeted. A lot of smokers have moved to vaping. Unfortunately, those left are often the ruder ones. Limiting where they cam smoke, or reduce expire for everyone else is a big dead for me.

    Additionally, it’s not banning nicotine, it’s banning cigarettes. Vapes have changes the balance on that one. They are less damaging, and cause far less issues with passive smoking. This acts as a pressure relief valve, rather than a blanket nicotine ban. Also, at no point will an existing (legal) smoker go from legal to illegal.

    The vape issue definitely needs fixing. A number have found advertising to younger users is a good money maker. Limiting the options here l, without an outright ban would help reduce the harm to children. It wouldn’t significantly affect ex smokers who moved to vaping.
