breput··on Fran Blanche: This Is Not Legal
tl;dw: Fran is a YouTube creator (mostly electronics and space videos) and has been having ongoing issues with illegitimate copyright claims made against her YouTube videos, including NASA public domain content and the sound of wind(!). She even has the physical copy of one Apollo 12 scene which she telecine'd to digital, uploaded, and then an unclear party made a claim against that video which is currently successful.

She also discusses "Visual Claim"[0] and how this will make things worse and how copyright trolls have nothing to lose with doubling down on illegitimate claims.

One issue I have with her is her insistence that alternative video platforms, such as Odysee/LBRY, will never have a chance against YouTube. That's definitely true today but anti-trust or other government action could eventually shake that up.

breput··on An update to paid sharing
That's the thing - you're probably not going to broach the subject with your brother as long as it doesn't really impact you at all. If Netflix tightens the screws, now you have an uncomfortable situation to deal with.

The smart move for Netflix would have been to silently transition the "freeloaders" to the ad-supported plan. They should have just done that without all of the dicking around in South America and under the radar. Freeloaders start seeing ads with a friendly link to upgrade to the paid plan. Maybe they do, maybe they don't, but Netflix gets paid either way.

breput··on An update to paid sharing
This is absolutely happening now and is a thing.

I downgraded to the $9.99/month SD one screen option because I asked and no one else was watching at all and now I'm rethinking even continuing with that. The upcoming ad-supported tier might be an option but I suspect many subscriptions will become very ephemeral.

breput··on Solar Car Will Soon Hit Production
They have built exactly 3 prototype vehicles[0]. They are nowhere near shipping even their first production model.

[0] https://aptera.us/faq/ "We’ve completed three Alpha vehicles, Noir, Sol, and Luna. We are currently finalizing development of our Beta vehicles and plan to begin production closer to the second half of 2022."

There is no way that rooftop area is even as large as a standard solar panel (say 200 ft²). Even the most efficient panel is no more than 350W, so you're cutting your "700 W" more than in half right off the bat. Discounting less efficient cells, road dirt, and non-perpendicular angles and we'll be generous and say 300 W.

12 hours/day is the maximum possible solar duration so you really need to cut that in half to account for a full year on Earth. So we're down to 1 kWh/day and realistically much less if you happen to park under a tree or a bird poops on your roof. That will hopefully get you to a charging station but not much further.

breput··on Solar Car Will Soon Hit Production
Also the 100 kWH battery pack is curious - a Tesla Model Y only has a 75 kWh battery pack and has a 300+ mile range. That is a ton of weight to be carrying around for a car that you would only drive a few miles once per week.
breput··on Solar Car Will Soon Hit Production
Sure. If that's your situation then leave the car outside 24/7 and it will probably work. Hopefully you have a secure, shade-free location.

The US DOT says the average miles driven per year is 13,476 miles. You could never ever do even a fraction of that solely with on-vehicle solar.

breput··on Solar Car Will Soon Hit Production
So less surface area in exchange for less air resistance? That's a difficult tradeoff when the A/C and other electric load devices will be constant despite the motive demands.
breput··on Solar Car Will Soon Hit Production
This can never work simply due to physics. It has a 100 kWh battery pack and no more than 1 kW maximum of solar panel capability, and probably quite a bit less due to the odd angles and less efficient panels.

EEVBlog did a video[0] on this concept recently and pointed out that his entire rooftop of ideally placed solar panels, in a nearly ideal location (Australia) could never power his own EV car. Backed up by real world data and common sense calculations.

Aptera themselves only claims "41 miles per day from sunlight under optimal conditions" which is the upper limit and will likely be a quarter or less in reality.

Compare this car to Tesla's prototype solar trailer[1], which easily has 10x the solar panel area as well as a battery. "If those are all 300W panels (and they look a little small for that), then the optimum output would be 2.7kW. That means it would generate less than 50 miles of range a day extended or a third of that folded up. "

breput··on Contra Wirecutter on the IKEA air purifier
There seems to be two main use cases for a room-sized air purifier:

If you live in a polluted city or are affected by wildfires, having a box fan-sized model is almost a necessity. It is going to be noisy and unsightly but undeniably more effective. Having a few furnace filters laying around for air quality emergencies is probably not a bad idea.

For day to day use in a low pollution area, where dust or pollen is the major concern, I really like the little 120mm fan purifier. It runs 24/7, unobtrusively, and is really effective for what it does.

breput··on Contra Wirecutter on the IKEA air purifier
You'll definitely want to bump thickness up to 2.0 mm for more rigidity. Otherwise just measure the diameter of your filter and maybe round up slightly.

I put a layer of electric tape around the flange where the filter adapter inserts into the filter and it makes a very nice airtight fit. Finally, just print it with the big end facing down and you shouldn't need any supports.

screwhole=5; // fan screw hole diameter (5)

filterhole=59; // HEPA filter hole diameter

thickness=2; // Thickness of plastic layer (1.5)

insert=10; // Length of insert into filter (10)

breput··on Contra Wirecutter on the IKEA air purifier
Well, my experience refutes that opinion, but yes, it sized for a smaller room or less polluted larger areas.

My office is approximately 12' x 12' x 8' or 1,152 ft³. That means the room's air would (theoretically) completely pass through the filter every 20 1/2 minutes. As the article explains, even the lower quality filter in the Ikea air purifier is so close to 100% efficient that it isn't worth worrying about, so completely filtering the air three times per hour is nothing to sneeze at...

And the cost is negligible - the fan might cost $0 to $10, filters are $20/year, and electricity usage is around 2 watts or probably under $2/year.

breput··on Contra Wirecutter on the IKEA air purifier
Big Clive made a video and wrote an OpenSCAD script[0] which allows you to 3D print a base and adapter to convert a regular 120mm computer fan into a "true" HEPA air purifier.

You might already have a spare 120mm fan laying around - I am using a $8 ARCTIC P12 fan[1] which is very quiet and is designed to work with high static pressure. The generic filters[2] are two for $17, (supposedly) H13 grade, available from a number of suppliers, and last a very long time. You could use them one at a time but I stack the two filters on top of each other and seal them with electrical tape for more surface area.

The fan isn't super powerful (56 CFM) and the appearance is not as polished as commercial models, but it does have a certain aesthetic to it. The area where I live rarely has any air quality issues but I have noticed it really cuts down on dust.

breput··on Why is Tiny Dancer such a great song? [video]
The best universe!

"I don't think it stinks because it is a rip-off. It think it stinks AND it's a rip-off"

But you're right - it is a huge series of in-jokes that are built on the previous videos. Starting at this video is right, then watching 1 - 5 in order is the right move.

breput··on Why is Tiny Dancer such a great song? [video]
Just in case you don't know, yet, this is a reference to Pat Finnerty's series of videos which calls out the pretentiousness of Rick Beato.

Start with https://www.youtube.com/watch?v=hQWfMI4CVFI but all of Pat's videos are incredible.

breput··on Ask HN: Was this a phishing attempt?
I think they were testing your ability to use "whois" and "dig". Amazon recruiters are tenacious so I wouldn't put it past them.

A couple of possible reasons:

* Double quotes are more visible, especially for triple quotes.

* It makes it easier to have text without having to manually escape apostrophes.

breput··on PDP-11 Booting
On the 11/70, Deposit was the only switch that toggled up (other than the light test switch). That is a nice safety feature so you don't accidentally toggle Continue or other action switches.

That is exactly what is going on but you don't need 3 way toggle.

Down is 0 and up is 1, you load all of the values in like a shift register but in parallel, then write/act upon them.

breput··on What it's like to ride 900 km in a day
You should look into the history of the Trans Iowa race[0]. It was a single "day" event (if you don't hit certain checkpoints in time, you're out) and was usually around 330 miles (530 km)...on gravel roads of all qualities. There was a separate division for single speed bikes. It was insane.

Not to dismiss RAGBRAI, though. It is a different kind of challenge - biking 50 miles in a day, especially with frequent stops, is no big deal. Sleeping in a tent, waking up, and doing it every day for a week especially with all of the nighttime activities is a different kind of challenge.

breput··on Packages dumped in wrong lobby, resident tried harder to correct it than Amazon
It isn't just Amazon. About a month ago, FedEx delivered several unexpected packages to my house. It was the right street but not even the same number of digits in the house number, so not close to being a honest mistake.

The intended recipient called the cops and FedEx tracked it down. It turned out to be several packages of gift cards, which is super sketchy, but other than a confusing experience with the police, I guess it turned out ok for everyone except maybe the driver.

breput··on Radio Station WWV
The reference frequency part is very important. There is a lot of test gear that relies on a 10 MHz signal for calibration.
breput··on Radio Station WWV
Shutting it down would have made every single existing radio controlled clock e-waste, overnight. And not just random wristwatches and wall clocks, but school and industrial clocks. None of these will work with GNSS signals.
breput··on Radio Station WWV
This, along with the WWVB station[0] that makes most of your "atomic" wall clocks work, is an underappreciated national (and international) resource that was almost shut down recently[1] due to budget cuts.

I'm not going to link directly to any of them because of the Hacker News hug of death, but do a web search for "websdr", find a US based or nearby location, and try tuning to either 5000 kHz, 10000 kHz, or 15000 kHz (depending on the time of day - lower frequencies are usually better at night), AM mode, to listen in.

That might be true (I don't know), but US Cellular is a CDMA/4G/5G carrier so there is at least some non-GSM functionality in there.
