While neat, this is not self-sustaining


it's taking more energy to power it than you're getting out of it. (You can build a fusion device on your garage if you're so inclined, though obviously this is much neater than that!)

One viewpoint is that we'll never get clean energy from these devices, not because they won't work, but because you get a lot of neutrons out of these devices. And what do we do with neutrons? We either bash them into lead and heat stuff up (boring and not a lot of energy), or we use them to breed fissile material, which is a lot more energetically favorable. So basically, the economically sound thing to do is to use your fusion reactor to power your relatively conventional fission reactor. Which is still way better than fossil fuels IMHO, so that's something.

My home town is in bald eagles' historic habitat, but there were never any growing up. In the past decade or so, they've started to reclaim it, which is pretty cool.

Yeah, we're destroying the planet, but we are doing some things right. And this sort of good stuff only happens because we fight for it.

The amount of money you save (and invest) isn't accurately depicted with this though. Living expenses don't necessarily grow with take home, if you keep lifestyle creep to a minimum.

So what this means is that if you make $100k and save $10k/year, if you start making $200k you can save the same $10k/year, plus the entire additional $100k after taxes (let's just say that's $50k+). So you doubled your salary but your savings went up 6x+.

Not sure why you're saying Python forces everything to be object oriented...?

Wouldn't 25 year olds still be in school for their doctorates though?

Yes, I think that's the point


they skew the numbers upwards.

"Chain migration" is how many people


myself included


get jobs.

I went to a very good school, and while I like to think the quality of education is what makes a school "good," let's be honest


the value is largely in your connections. Friend lands a good job, recommends you when there's an opening, and bam, you're already at the top of the pile of the CVs (better yet, they're the hiring manager).

Friends from school


peers and mentors alike


are a great place to start, if you can. Ask to grab a coffee and chat about their career, and be clear that you're in the market. Most people are happy to chat (at the very least, it's flattering).

It's the way the world works...

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.

When I took some astronomy classes in the early 2000s, Jocelyn Bell was absolutely credited. In her own words:

It has been suggested that I should have had a part in the Nobel Prize awarded to Tony Hewish for the discovery of pulsars. There are several comments that I would like to make on this: First, demarcation disputes between supervisor and student are always difficult, probably impossible to resolve. Secondly, it is the supervisor who has the final responsibility for the success or failure of the project. We hear of cases where a supervisor blames his student for a failure, but we know that it is largely the fault of the supervisor. It seems only fair to me that he should benefit from the successes, too. Thirdly, I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases, and I do not believe this is one of them. Finally, I am not myself upset about it - after all, I am in good company, am I not!

That said, yeah, I think she absolutely should have been awarded the Nobel prize. But while she did not, she has the admiration


rightly so


of many a budding astronomer.

Reminds me of that West Wing episode where he "accidentally" makes an offensive gun analogy comment; Harris doesn't really alienate any supporters here, and she appeals to the undecided gun crowd voters. As a bonus, she's "telling it like it is" for folks who are self-described as being "fed up with PC culture."

I just tried that and got the same result. It's from a site that just quotes a snippet of an Onion article 🤦

One of the real downsides of ARM is, it seems, the relative lack of standardization. An x64 kernel? It'll run on most anything from the last ten years at least. And as for boot process, it's probably one of two options (and in many cases one computer can boot either legacy or EFI).

ARM, on the other hand...my raspberry pi collection does one thing, my Orange Pi does something else, and God help you if you want to try swapping the Orange kernel for the Raspberry (or vice versa)!

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!

Similar with Y2K


it was only a nothingburger because it was taken seriously, and funded well. But the narrative is sometimes, "yeah lol it was a dud."
