BirdNet, from Cornell University, is pretty cool. I've got a RasPi4 that's been running birdnet-pi for about a year and a half, seems pretty accurate based on the birds I see in my backyard. It'll also run on a $20 Pi Zero 2.
There is an element of truth, but what you're describing still sounds like a scam. Power factor correction is legitimate, but it's not something that can be done with a generic product that you hook up to any appliance, or even your whole house.
Same here, and I think it was also obvious to Jeff (from the OP), but I'm glad he bought one because he's in a position to raise awareness of the issue.
The unit is arbitrary. Let's say 1 unit of measurement equals the radius of the wheel. As long as they used the same wheel for all sides of the pyramid, each side will follow the formula: n * 2 * pi where 'n' is an integer (whole number). The formula could easily be written in any other unit of distance by multiplying by the conversion ratio.
You're assuming this heater is on grid power. We just need to power it by solar panels that are inside the house, under a skylight. Now we've got a 100% efficient heater, just don't ask about PV efficiency...
Kind of like how if you take a bunch of traditional radar systems, sync their LOs, and add some DSP, you get a phased array. Pretty good analogy, actually.
Depends on your definition of homelessness. Living in a shitty, broken down van probably counts. But what about living in a $200k Mercedes Sprinter van converted to a camper, with a stable job that lets you work remote? What about a retired couple living in a 40' RV, after spending their working lives dreaming about traveling around the country?
I didn't watch the video, and I only found out about the blog post through Lemmy.
IMO the blog and video seem a little click-baity. Yes, he technically does acknowledge (in the video, not the blog) that older Pi models are still being produced, but saying the SBC market is dying is crazy. How many projects really need the specs of a Pi 5 in that form factor? If you need that performance, you probably have space for something a little bigger.
Here's the author's own tl;dr:
But if you'd like the tl;dr:
Unless the DRAM pricing situation changes radically, I think the hobbyist SBC market is dying—or at least on life support. And I don't just mean Raspberry Pis, but all SBC vendors. LPDDR chips now account for the majority of board cost from the vendors I've checked with.
Raspberry Pi would have been fine if they stopped at the Pi 3. I'm not saying they shouldn't have made the 4, or even 5... but the Pi 3 and Zero 2 are (IMO) their best products in terms of price-to-value. The SBC market is fine.
The thing that these complaints about RPi pricing always seems to miss is that most Pi models are still manufactured and supported. Most projects don't need a Pi 5 with 16GB of RAM, even a Pi Zero 2 (under $20) is overkill for a lot of projects.
I interpreted their question differently. It sounds like they're taking about Radarr having to download a movie before they can watch it, whereas streaming services have a "complete" (compared to a new *arr setup) library available to stream instantly.
Some bittorrent clients can start playing a video before it's done downloading, and prioritize the torrent chunks in the right order so there aren't any interruptions as long as there are seeders and you have enough bandwidth. But I don't think plex or jellyfin can do it, and I don't know of any alternatives that can.
Until a few years later when all the used TVs have cell modems. The same thing is already happening in the used car market, it's getting harder and harder to find a reliable vehicle that doesn't have a cell modem and a long T&C that let's them spy on you.
Cell modems are getting cheaper and cheaper, it's only a matter of time before cheap smart TVs will flood the market with always-on telemetry and intrusive personalized ads.
