  • It is more than just the concern around back-feeding the grid. These simple balcony setups connect to your home grid via a single outlet. Most US outlets/circuits are 15 AMP or roughly 1500 watts max capacity. These single circuits can only carry that much current total at any one time so if you have it loaded up with incoming power AND use anything else on the circuit at the same time … no bueno. To make this setup work best/safely you would ideally want a dedicated circuit for it which is basically non-existent today.

    The safety issues really do need to be addressed because the folks most likely to use these systems are apartment dwellers and I don’t think anyone wants to increase fire risk in these scenarios.



  • Nokia 2780 is not bad. It runs KaiOS, supports tethering and 4G cell data. As long as you stick to the script on how you use the device it will have minimal privacy issues IMHO. If that is still not enough you can skip phones altogether and get a 4G dongle for your favorite Linux laptop/tablet and just use a softphone + voip service.







  • We need improved Linux support for power management on ARM platforms. In general Linux on ARM has been good for a long time now. (ex RaspberryPi, Gentoo, Ubuntu)

    Where things aren’t so great is the choice in OEMs putting out ARM parts like Broadcom, Qualcomm and Apple. All of whom aren’t exactly open source champions. In a less imperfect world we’d have something like RISC-V with great power management and linux support available in mobile computing SKUs/TDPs.





  • Assuming that:

    • your Linux Laptop uses wlan0 for its wireless connection and your home network uses 192.168.1.x for IP space.

    On the Linux laptop:

    • as root or with sudo – enable IP forwarding and load the change with sysctl -p.

    sudo sysctl net.ipv4.ip_forward=1 ## updated edit thanks to folks pointing out my typo.
    sudo sysctl -p

    • if you have ufw installed and running – setup a NAT masquerading rule for any hosts forwarding IPv4 traffic to it.
      add this line to /etc/ufw/before.rules file right after the “*nat” line

    :POSTROUTING ACCEPT [0:0]

    -A POSTROUTING -s 192.168.1.1/24 -o wlan0 -j MASQUERADE

    On the mac:

    • set your IP address manually to be on the same LAN as the Linux laptop, but for the gateway address… point that at the IP for the Linux Laptop.



  • Is it easier to secure, monitor fewer, bigger reactors or thousands of* small ones? Accidents are still going to happen and I know which scenario makes more sense to me. Especially in light of Trump’s recent push to deregulate nuclear energy, kill the EPA, and pretty much any other kind of sensible management efforts of technology that is great until something goes wrong then it quickly becomes a multi-generational clusterfuck.

    Solar, batteries and long-range transmission infrastructure just makes too much sense I guess.
