With coherent detection I think the separation between eyes would allow for this.

Except that this problem doesn't specify distance between horseman, so I think it's a bit bogus


no need to resolve an individual person to be able to tell that they're there. And for hair color, if you make assumptions about the clothes being worn, you could perhaps infer color of hair, even if the hair isn't resolvable (a person being a "single pixel" would have a different hue depending).

Or, "the problem" is an uneducated electorate: https://www.insidehighered.com/news/government/politics-elections/2024/11/08/men-and-white-people-vote-differently-based-education

Whether this is due to "book smarts" or just a statement that going to college means you meet different people and generally expands your worldview, it seems to make a difference (men still more problematic than women, but less so when educated!).

Dipoles are, effectively, not


so if you have a charged bit and another opposite charged bit, while an inverse relationship might exist between either one, the net effect is that it drops off much faster.

The thing with gravity is it tends to go one way, unlike, say, charge.

We're in the market for a kid carrying ebike, and while REI makes the most financial sense, I think we'll be paying a visit to our LBS.

As an aside, I tend to prefer Sports Basement. Have had better luck with their bike department, too. No idea if they're better from a corporate standpoint though.

This is the real big brain hack with decibels


you can use a linear scale, it's just that the units are logarithmic instead.

(Yes I know most people would call a dB axis logarithmic, it's just a silly comment.)

My $4k piece of carbon and $3k hunk of titanium would like to have a word...

I would bet just about anything that the only reason profit margins could possibly be higher for a car is due to volume


which, if everyone rode bikes, wouldn't be an issue at all.

Absolute profit, sure


cars are more expensive, so they'll win out.

We still use leaded gas for aviation, as does (I believe) the EU (I'm guessing RoW, too).

(Supposed to be banned this year in the EU but AFAICT pushed back until 2032.)

Deja vu is usually a glitch in the Matrix. It happens when they change something.

You can have a lot of smart functionality and remain local-only (e.g., Home Assistant). All my smart devices are on their own VLAN with no Internet access


if something breaks it's not the cloud's fault, it's mine.

Fail2ban config can get fairly involved in my experience. I'm probably not doing it the right way, as I wrote a bunch of web server ban rules


anyone trying to access wpadmin gets banned, for instance (I don't use WordPress, and if I did, it wouldn't be accessible from my public facing reverse proxy).

I just skimmed my nginx logs and looked for anything funky and put that in a ban rule, basically.

And probably only the second half of the 2nd amendment.

 

People often complain about San Francisco's public transit


and to be sure, it's not perfect by any means (multiple separate agencies doesn't help). But the historic streetcars are pretty neat!

They're painted with the livery of various historic streetcars from all over the country (and a few international, I think). Best of all, they run alongside the modern fleet


same route, same fare.

 

Noticed a few days ago that Sutro Tower's red blinking lights are now white. Just asked them on their website form, but wondered if anyone else knows the story with this.

Personally, I miss the red ones!

Howdy!

I got my Technician in early 2000s, and last year finally upgraded to Extra. Looking to set up a very basic shack.

I'm looking for an HF setup, with most of my use probably using digital modes, but would like the ability to use voice.

Current transceiver is on loan from girlfriend's dad, a Ten-Tec Scout 555


50W HF unit with separate modules for each band. One limitation of this is that the modules set the mode, so it's LSB on 40m, making e.g. FT8 not possible (without some hacking of code or perhaps hacking the module).

Antenna is end-fed with an off-the-shelf 49:1. Currently only have 20m half-wave, but have just enough room for a 40m half-wave in the attic, which is the ultimate goal.

For digital modes, it looks like there are sort of 3 classes of radio:

  • "full digital" where the radio has e.g. a USB port and handles audio, transmit, and frequency set.
  • Some computer-control with RS232, but uses computer audio+adapter to transmit.
  • No digital, use adapter to transmit. This is what the current setup uses (and it works great!)

I'm leaning towards a conventional transceiver, e.g., something from ICOM, Kenwood, Yaesu, (or others) rather than an SDR unit. I'd like the ability to go up to 50-100W if possible.

I don't have a hard-and-fast budget; would like to keep it <$1000 if possible; mostly just looking at used transceivers. Something like a Kenwood TS-590 looks pretty amazing and very "plug-and-play" (but pushing up against price). Something like a Yaesu FT-920 looks pretty feature-rich too; and even something more affordable like an ICOM 706 or even a 725 is probably more radio than I need. Or just grab a new 7300 and call it a day!

Anyway...clearly, I don't know exactly what I want, but figured I'd ask folks with more experience if they have any wisdom. Thanks!
