probably because they already own it.

use some file system with snapshots and differential backups, like ZFS, and snapshot it daily. Stream the diffs somewhere they can’t login to and which doesn’t mount the FS.

This will invariably save their bacon at some point.

Lemmy.ml seems to have a clone of most of the “top reddits”, somehow the most subscribed communities out there, and all dominated by one or two posters who post pro-China/pro-DPRK/anti-Western content all day long.

It definitely is going to confuse newcomers and make a bad first impression. I wonder if they auto subscribe people to those so their propaganda ends up at the top of the communities list.

Part of the solution is to better inform new users the part of the community name is the host, just like Main St in one city is different from Main St in another city. You choose the city you want to live in first.

But, it may also be interesting to have the ability for admins to selectively merge like-named communities with other agreeable instance admins, and count subscribers to both as one group.

The thought of going through all of my storage boxes to catalog hundreds or thousands of items so that I might search for them one day via a web UI seems a lot less productive than simply knowing that old USB supplies are in the “USB junk” box and Christmas decorations are in the “Christmas decorations” box

You built a spambot?

if you weren’t constrained on the tinyness of the array or its complexity, sure.

But how you gonna get a light-frequency signal down a conductor to the antenna? It would just be light you’d be powering your antenna array with.

so, I consider a DMD or a hologram a device along the lines you mention

I gave up on cute or clever names a while ago; now I go with “storage0”, “router0”, “wap00”, “vmhost0”. Always with a numeric suffix because there will be a -1, -2 some day.

Zigbee or Zwave temperature/humidity sensors are common. Add a 3-circuit relay box and you can simulate the behavior of pretty much any thermostat with a few rules.

HA or any other system that can toggle outputs based on sensor thresholds would work just fine.

there are some subtleties with real HVAC thermostats, like running your AC compressor at least five minutes and ensuring that it stays off for at least 5 minutes when it’s turned off.

Both my Google and At&t gigabit fiber plans have been symmetric and post about 850-900mbit both ways.

Cable (DOCSIS) customers will always have lower UL because of the limited shared upload channel compared to multiple bonded download channels.

ADSL customers are in a similar situation, with the modems configured to allocate 90% of the channel to downstream (which makes sense for the vast majority of users).

Cellular customers will always have lower UL because of handset power/antenna limitations and transmit power ranging.

there’s this bizarre contingent of very vocal users who go nuts, pushing back against any actually achievable non right wing stance, and go on and on about how “liberals“ are evil and not “left”. I believe they are plants who’ve been given the job of dividing the left.

Never good to intentionally pollute.

in your antenna, the outside of the coax makes up part of the radiating structure. The orientation of the elements in relationship to that coax will definitely change the radiation pattern, maybe for the better maybe for the worse.

putting ferrites around the coax right below the antenna feed point will make the antenna more symmetrical as it blocks RF currents traveling back down the outside of the shield.

A 1/4 wave monopole above 1/4 wave radials is also a balanced antenna. unless the coax is carrying common mode currents, the antenna is balanced.

It does not matter. (It does not matter in a “ground plane” antenna either, the radials have nothing to do with the earth other than being easier to mount with the coax heading downward; in fact, radials should not be touching or buried in the earth as they are RF radiators and RF faces high losses in soil)

Neither side is ground. Due to electromagnetic field behavior, coax carries equal and opposite AC currents on the inner conductor and the inside surface of the shield; those equal and opposite currents drive the two dipole elements.

RF doesn’t penetrate shielded boxes and coax shields - so the outer surface and inner surface of the coax shield are seen as two different conductors at RF. In the pictured dipole, RF can flow out of the coax and back down the outside (and around the outside of the shielded receiver it’s connected to) because the open end of the coax “connects” them. So the coax shield is very much energized with (and receiving) RF; generally a ferrite bead choke is used to mitigate the unwanted shield currents.

With RF, “ground” doesn’t mean very much. There always has to be a circuit for current to flow; tying some point of the circuit to the chassis or to the power supply negative does not “zero it out” at all.

Usenet or Fidonet would be a more apt comparison

yeah, communities should have subject tag sets. I don’t care for anime or sports or video games - i should be able to turn off those tags. Not block 50 different game communities ad hoc

Surge suppressors do not drop extra voltage to ground. They selectively short out surges between whatever two conductors have a high potential between them.

No ground conductor means there cannot be a high potential between it and anything else!

honestly, I don’t want established Reddit supermods land grabbing topics in the Fediverse. The right people will find it organically based on their own motivation (as simple as searching for “reddit alternatives”).

Especially don’t want the shallow, low-quality content from default/“top” subreddits.

“prove it wrong”? “as we’re told”? Do you start conversations this way?

Bro, if you don’t like it you don’t have to use it.
