If you have a TV, you likely already have the receiving device. Antenna can cost, or you can play around with wire length and orientation.

It's mostly so that I can have SSL handled by nginx (and not per-service), and also for ease of hosting multiple services accessible via subdomains. So every service is its own subdomain.
Additionally, my internal network (as in, my physical LAN) does not have any port forwarding enabled
everything is over WireGuard to my VPS.
My method:
VPS with reverse proxy to my public facing services. This holds SSL certs, and communicates with home network through WireGuard link configured on my router.
Local computer with reverse proxy for all services. This also has SSL certs, and handles the same services as the VPS, so I can have local/LAN speeds. Additionally, it serves as a reverse proxy for all my private services, such as my router/switches/access point config pages, Jellyfin, etc.
No complaints, it mostly just works. I also have my router override DNS entries for my FQDN to resolve locally, so I use the same URL for accessing public services on my LAN.
We tend to use between 3kWh (vacation/idle power consumption) and around 8kWh per day. If we switched to electric stove, water heater, and heat pump, and add a hot tub, that'd increase substantially. But if we added solar (on our long Todo list...), the battery in the article (60kWh) would probably be able to handle all our storage needs, and it'd fit in he garage (bonus of it can be placed outside/under a deck!). I live in a major city, but I would absolutely love to effectively be off grid.
Exciting stuff
it seems these are touted as being extremely robust/safe, which is of course important for me if it's going to be in/near our house. Storage density not a huge concern, but price is somewhat important
let's hope this sort of thing ticks all the boxes.
And your VPN connection to work knows your endpoint...
Interestingly, there's another way of finding out if your coworker is in the office
just walk over to their desk.
The one I've heard replaces "brains" with "money."
Calmer than you are.
"Boston Elites"? I can't believe Tom Scholz and Brad Delp would do this :(
It can be daunting to get into the hobby, there are a ton of niches.
To start: where are you? I'm in the USA, so that's where my experience is.
License: required to transmit on the ham bands; you can listen without a license.
Range: are you looking to talk to people in your city/region? If so, a cheap "walkie-talkie" style (called "HT" in the biz
best avoid "walkie-talkie") is a good place to start. These VHF/UHF (very/ultra high frequency) radios are affordable
something from Baofeng(~$30) or similar will work just fine, though they are often looked down on (I have one
for the price, it's great). You will have the most luck if there is an active ham scene in your area, in large part because they may have a repeater, which can greatly extend your range. Many regions will have scheduled "nets" where you just go around and chat.
If you're looking for the ability to chat with folks on the other side of the world, you'll want to look into HF (high frequency). This is much lower frequency, thus longer wavelength, than the handheld VHF/UHF HTs. So...the antennas take up a lot of space. Mine is 52 feet long, in the attic. And the radios are much more expensive (more like $1k new). ICOM 7300, Yaesu FT710 are popular entry level units (but you also need power supply, cables, and antenna).
That said: if you just want to listen to HF, the antenna doesn't matter as much at all, and you can use an SDR (RTL-SDR probably works?) for listening. You can probably also find a used shortwave radio that covers some of the HF ham bands.
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.
I think they mean just the domain name, but not positive.
The Picosecond Pulse Labs bias tees hold a special place in my heart.
