  • I’ve been happy with the GE Enbrighten series, though they do require a neutral wire. I use the Z-Wave models, but I can’t imagine the ZigBee models would work any differently.

    Neat feature of the Enbrighten line is they recognize several gestures including short tap, long press, double tap, and I think even triple tap. I configured mine so that short taps on/off toggle the lights between off and 100% on, long press on/off brightens/dims, and double tap on activates the preferred evening lighting scene.

    I think Minoston are also a GE product line? Again, Z-Wave, but rated for higher wattage in my case. They also require a neutral wire.

    I had a pair of no-neutral ZigBee switches sold as ‘Martin Jerry’ brand, but they were super dodgy. Terrible feel to them, and they made a sort of electrical whine when the fixture was on. I pulled them right out and sent them back.




  • You could source a pair of gigabit media converters and a length of fiber on Amazon for about $100. Just use the media converters to extend the Ethernet port from where the Internet hands off in your house over to your office. You can affix the fiber along baseboards and up over door frames with adhesive cleats and zip ties, or those nylon staples on a nail they use to tack down coax cable.

    If you’re willing to spend a little more on the fiber for a custom color, you can probably even order the fiber in a more neutral color than SMF yellow to blend into the trim better.

    The rankness of a fart can be expressed in decibel-Farts (dBF), a logarithmic scale where dBF = 10 log10(F1/F2).

    Characterizing F in standard units is a bit of a chore, but broadly speaking the resolution concentration of hydrogen sulfide (H2S) in air for humans-- the concentration at which 50% of people can detect its odor-- is about 4.73ppb, or 4.73 x 10^-9.

    A cubic meter of air at sea level (1 atm or 760mmHg) at 15°C contains about 2.53 x 10^25 molecules of mixed gasses. Scaling to a cubic meter, the volume for detection of H2S for humans would be about 1.19 x 10^17 H2S molecules per cubic meter. This value is your F2, our reference intensity for detecting farts.

    A typical human fart has a concentration of anywhere between .001ppm and 1ppm of H2S concentration, or between 1x10^-9 and 1x10^-6, or scaled to between 2.53x10^19 and 2.53x10^22 H2S molecules in a cubic meter of air.

    Therefore the rankness of a typical fart could be expressed as a decibel ratio vs the resolution density falling somewhere between 23dBF and 53dBF.

    This is a useful expression of rankness for modeling attenuation over time, accounting for dispersion, wind drift, and distance from the zero point.

    If you just want each physical interface on your server to participate in a single VLAN, set the corresponding switch port as an access port in the desired VLAN, and then configure each server interface as a normal untagged interface.

    You would only do tagged frames (802.1q trunking) if you wanted to support several VLANs on the switch port.






  • It’s mainly about managing risk, but also not all ISPs allow residential accounts to host services on their IP addresses.

    Opening a port to the internet exposes the service to the whole internet, which means you need to secure the service with strong credentials, set up SSL, manage the certificate, and keep software up to date. You incur a lot of extra work, and also extra risk not only to your self-hosted service, but to any other services you host that “trust” your service.

    All that work requires extra knowledge and experience to get right which, let’s just be honest here: we’ve all probably followed that one How-To blog post, and maybe not understood every step along the way to get past that one pesky error.

    Running a secure VPN overlay like Tailscale has much less overhead. You generate some keys, and configure your lighthouse server so the enrolled devices can find each other. It effectively extends your LAN environment to trusted hosts wherever they might be without exposing any of the services to the Internet.

    Overall, Tailscale is simpler and much less work for individuals to set up and maintain than to secure multiple services against casual or targeted intrusion.

    Tailscale also has the benefit of being a “client” in the view of the ISP, who see your IP address reach out to your VPS to initiate the tunnel, and not the other way around. If there’s any CGNAT going on, Tailscale would tunnel through it.
