  • 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.

    Air at sea level (1atm or 760mmHg) at 15°C contains about 2.53 x 10^25 molecules of mixed gasses, so the resolution volume of a H2S in humans is about 1.19 x 10^17 H2S molecules per cubic meter at 1atm at.15°C. This is value is your F2.

    A typical human fart has a concentration of anywhere between .001ppm and 1ppm of H2S concentration, or between 1x10^-9 and 1x10^-6, thus between 2.53x10^19 and 2.53x10^22 H2S molecules.

    Therefore the rankness of a typical fart could be expressed as falling somewhere between -90dBF and -60dBF.

    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.
