This is obvious though


currently, you might test a drug on mice, then on primates, and finally on humans (as an example). It would be faster to skip the early bits and go straight to human testing.

...but that is very, very, very wrong. Science of course doesn't care about right and wrong, nor does it care if you "believe" in it, which is the beautiful thing about science


so a scientifically sound experiment is a scientifically sound experiment regardless of ethical considerations. (Which does not mean we should be doing it of course!)

Now, taking a step back, maybe you're right that, in the long run, throwing ethics out the window would actually slow things down, as it would (rightfully) cause backlash. But that's getting into a whole "sociology of science" discussion.

I miss the days when that X font was only associated with Xorg...

This is all based, most likely, on Griffiths' textbook. Quoting here from this post https://www.reddit.com/r/Physics/comments/1b97gt/magnetic_fields_do_no_work_but_magnetic_cranes/ :

The statement "magnetic fields do no work" is incorrect. Griffiths has mislead a generation of physics students on this. A correct version of the statement is that "magnetic fields do no work on objects with no magnetic moments" which is rather trivial. One could also correctly make the same statement about electric fields. However, electric monopoles are very common, so a situation in which there are no electric moments never occurs in normal circumstances.

tl;dr: use Jackson ;)

Or it's rage baiting/humor 🤷

Unity centered around what?

Participation. Making things a tiny bit better when possible, and if not that, then minimizing damage.

Making things better nationally is hard. But locally, change can be efffected


my city (San Francisco) has ranked choice voting for local offices. It's awesome, and I vote for who I want first. It's small, but it's a start.

Depends on the person


when the pandemic hit I was a grad student, we didn't have kids, and our living situation was nice (tiny studio but it had a wonderful, if small, outdoor space). Scary times for sure, but life


at least the day to day


was...pretty good!

Now we have kids, and my god, I can't imagine.

Jobs created toxic work environments.

...and so did Linus Torvalds*


he's certainly not the embodiment of capitalism. But I absolutely have a huge amount of respect for Torvalds, even if I don't approve of his way of interpersonal/professional style.

(I used to run Arch btw [but I run Debian now].)

*He's supposedly taken steps in the right direction here and has made improvements.

Not sure if trolling or not, but googling around and it sounds like Sensory Processing Disorders can cause this level of passionate hatred towards bananas...

On linux you can"t install or uninstall anything if you are not root

That's not true at all. You generally can't use your distribution's package manager to install or uninstall without elevated privileges. But you can download packages, or executables with their own installer, and unpack/install under your home directory. Or, you can compile from source, and if you ./configure'd it properly make install will put it under your home.

Standard Linux distributions don't place restrictions on what you can and cannot execute; if it needs permissions for device access of course you'll need to sort that out.

Yeah, without being a policy junkie I think a reasonable step would be to have Prop 13 only apply to primary residence


investment real estate would be subject to a "wealth tax," but folks wouldn't get priced out of their primary home due to gentrification.

[–] [email protected] 4 points 1 week ago (3 children)

Right, that's a huge downside for sure.

Property tax is on the one hand a wealth tax, which sounds like a great idea; but on the other hand, it's a wealth tax that disproportionately affects people with the bulk of their assets tied up in real estate


which often means middle class homeowners.

So while you can certainly look at prop 13 as "good" in that folks don't get priced out of their existing homes, it of course gets used to the advantage of rent seekers, etc.

It's...complicated.

 

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!
