threemux··on How the U.S. government could lower food prices
This is an example of where coming to the comments first saves you a click - this is just price controls packaged differently. Price controls not working is about as consensus a view as you can get in economics. In their example, you don't get cheaper Pepsi, you don't get Pepsi at all.

Hilariously, they mention price and wage controls during WWII as an example of it working! I think that's up for debate to put it mildly. One famous thing that came out of wage freezes at that time was health insurance provided by employers. Had to attract talent somehow and salaries were capped.

More broadly, I don't believe humans have the capacity to foresee second and third order effects of policies like these which is what makes them so dangerous.

threemux··on Tiny UPS for Tiny NAS
This product is great - it seems to be intended for internal installation into desktop towers, but it is infinitely configurable and can operate as a portable power pack with user-selectable (via dip switch) output voltage. 3-D printed enclosures are online at the usual places. I use it as a UPS for my router.
threemux··on It will never be a good time to buy a house
One thing the government could do right away that would serve to spread out good jobs is move executive branch departments to other states. For example, let's move the USDA to somewhere in the Midwest. Government employees would move there as would contractor staff and all kinds of ancillary business serving the above.

Remote work helps too but the increase in supporting businesses that serve onsite employees is important for an area

threemux··on ARRL hails FCC action to remove symbol rate restrictions
~10 watts into a dipole is plenty for both CW and modern data modes. SSB is harder but still doable. ARRL is right it probably limits its use for emergency interop, and I do support their proposal to keep the 100w limit. However, if the FCC goes with its original proposal I won't lose any sleep. Perhaps it can be a haven for QRP operations. The propagation on 60m is quite good day and night.

Yes unfortunately "model craft" is not defined anywhere in Part 97 that I can find.

I can't say I understand the rest of the first paragraph - Part 97 doesn't actually ban encryption, just "codes or ciphers intended to obscure the meaning of the communication", from which "telecommand of model craft" is specifically exempted.

I'm not as familiar with the Part 15 rules - do they allow high gain antennas? Since this case is about stationary command and control, I wonder if lower power + high gain wifi antennas at both ends would close the link.

threemux··on ARRL hails FCC action to remove symbol rate restrictions
Doesn't this fall under the "telecommand of model craft" exception?

It seems to me encrypted ssh is totally within the rules in this case.

What countries allow general encryption on the ham bands (e.g. not limited exceptions for particular cases)

"The hobby is dying" has been a trope longer than nearly everyone in this thread has been alive - give it a rest.

We've always had allocations because there wasn't a commercial use for it. As soon as there is, we lose it. See the loss of part of 220mhz and all the higher frequencies we're in the process of losing to 5G/other commercial use. I recommend embracing this reality

threemux··on ARRL hails FCC action to remove symbol rate restrictions
Eh yeah I've heard these. The important bit to remember is Part 97.113 on prohibited transmissions: "Communications, on a regular basis, which could reasonably be furnished alternatively through other radio services." That's the bit that trips these up rather than the encryption prohibition.

The common case: this is vague and probably falls under the above. What's an example?

The basic case: use phones. All of us that have spent time on HF are well aware of the antisocial behavior sometimes found there. I don't think you'll run into any ham that's against stricter enforcement in this area.

Public service: SHARES is probably the move here. I think I would support waivers similar to how they were previously allowing PACTOR 4 though. Despite what the ARRL says I'm a little dubious of our utility in disasters these days in any case.

I mean sure you can come up with any number of ways to get away with it but that doesn't mean we should endorse that behavior.

threemux··on ARRL hails FCC action to remove symbol rate restrictions
Well we're not really being kicked off, the FCC is proposing to change the allocation to match what was agreed to in WRC-15. This page summarizes:

I see these takes pop up all the time but I have yet to hear of a legitimate use case that wouldn't be solved with digital signatures which are allowed under current rules
threemux··on Auto industry executives admit electric vehicle plans are in jeopardy
Electric cars would have to suck pretty bad for someone to spend twice as much, I'm not sure that anecdote is saying what you seem to think it is.

They might be saying "In an ideal world I'd drive a gas car, but the electric car is good enough where I'd rather not pay double." I don't think the person I was responding to was saying they "sucked", just that they had drawbacks.

threemux··on Auto industry executives admit electric vehicle plans are in jeopardy
The bar for "good enough" is artificially lower in Norway when it comes to EVs. I'm not sure if you're aware just how huge the subsides are for EVs in Norway. They are trying to reduce these a bit and I'll be interested to see how that affects purchasing patterns. You're exempted from a punishing 25% VAT that gas cars are subject to first and foremost. Also, electricity is very cheap in Norway due to their abundance of hydropower.

threemux··on Auto industry executives admit electric vehicle plans are in jeopardy
EV suffering range loss in cold conditions is well documented. Norway has tons of EVs purely because of massive government incentives.
threemux··on FCC wants to bolster amateur radio
I think the proposed rule to replace the baud limits in VHF and above will make more of a difference.

All the major weak signal HF digital modes use low baud rates anyway to better deal with multipath interference that's common at those frequencies. Really the only mode we couldn't use here was PACTOR 4 - that was the mode people kept getting waivers of the rule for.

threemux··on Stockholm to ban petrol and diesel cars from centre from 2025
I don't think this deserves to be downvoted. Alas the "you'll own nothing and you'll like it" / "you'll go where we say according to our schedules and you'll like it" crowd is strong here.

You're right of course that not having a car self-evidently limits the things you can do (yes even in your country that has flawless transit that is free and goes "everywhere"), and is even worse if you have children. Want to go to the country to relax? You're limited to the places you can get by transit. Kid wants to do something that isn't near a transit stop? Too bad. Visiting relatives outside the city? Better hope you can get a ride from the nearest transit stop. The list goes on and on.

Being able to walk places is desirable, but it's best when you can walk/bike and drive a car if you need to.

threemux··on Eliminating radio interference from Apple charger
OP appears to be Finnish judging by the OH callsign - perhaps his regulator cares about all the interference to the amateur bands from cheap electronic devices. As a fellow ham I can assure you that the FCC does not care about interference from these devices if they are only causing issues for amateurs. If all the cheap switching power supplies and other devices were actually tested, almost none of them would be RF quiet (or even compliant). However the large majority of the public is not impacted by these things and so there is no real constituency to get something done.
threemux··on The Upcoming Mazda RX-9 Will Keep the Spirit of the Rotary Engine Alive
The "Skyactiv-X thing" absolutely works and is available on Mazda 3s in Europe now. It doesn't work in the US because of our very stringent NOx emission rules (which, incidentally, is one of the reasons diesels are less popular here). I'm not aware of Mazda trying a Miller cycle engine outside of one trim level on the Millenia. I have heard that their experiments with that helped the development of their Skyactiv engines in general though. I'm also not aware of anyone else making Miller cycle engines currently. Perhaps you're thinking of Toyota's heavy use of the related but not the same Atkinson cycle engine.
threemux··on The Upcoming Mazda RX-9 Will Keep the Spirit of the Rotary Engine Alive
You may be interested to read about the first generation Honda Insight and/or the Honda CRZ. Both were hybrids that were available with a manual transmission. But as another commenter has already explained, Mazda's setup here is very different from anything currently in production.
threemux··on The Upcoming Mazda RX-9 Will Keep the Spirit of the Rotary Engine Alive
If they pull this off (especially if it's possible to do all-electric at low speeds for short distances) I'll be on the preorder list for sure. A manual would be preferable, but that may be too complicated to allow given the powertrain setup.
threemux··on Organic Maps
A fantastic app that has saved me a few times when I didn't have service. I know they're actively working on Android Auto support and I'm eagerly awaiting it!
threemux··on Michael Burry shorts Major index in sizable bets
This guy was very right once and has basically been wrong ever since - why is this interesting? Remember his massive bets on water and disastrous short position on Tesla?

threemux··on California Strip Malls to Be Upzoned Tomorrow
This is an interesting way to frame something I've seen stated as "if you don't own the land you don't get to decide what to do with it". I can't say for certain if people would be willing to pay above "market" for more space in all areas, but I think they would in some.

Your comment is not part of this and is thoughtful, but it does touch on the anti-democratic streak present in the YIMBY/urbanist community. At its worst, this attitude is essentially "I know better what is good for this area than the people that live there" which has had disastrous consequences historically

threemux··on California Strip Malls to Be Upzoned Tomorrow
The value of some places is the very fact that they're low density. I don't think that applies to strip malls necessarily, but this is why people come out strong against upzoning suburban or rural areas. The people that live there like it the way it is, and you can't give more people that experience as more people ruins what's good about it.
threemux··on Refurb weekend: Cobalt RaQ 2
I've been interested in putting one of the MIPS variants of these into service in my homelab, but I can't find a reasonably priced one. It seems the x86 ones are most common on ebay
threemux··on Haiku package management
This reminds me of TinyCore Linux, which distributes packages as squashfs archives and dynamically mounts them at runtime with symlinks to the system directories. Pretty neat.
threemux··on Airbnb nightly rates shot up 36% in 3 years
Nailed it. Everyone saying hotels are a better option are one or more of:

a. Childless

b. Vacationing in a popular/populous area where there is hotel choice

c. Not in the USA (I've gleaned from these threads that hotels with spacious suites are more common in Europe)

threemux··on Ask HN: Airbnb requires my credit-card transaction history?
> How can you compare two things when one of them is not available?

The example I gave is explicitly where they are both available. A hotel near my extended family, or a detached house from Airbnb that has bedrooms for my kids and a full kitchen for a similar price as two rooms in that hotel.

> most of the time hotels are better

That which can be claimed without evidence can be dismissed without evidence.

> a large family with multiple children

I'd posit it's better with any amount of children, especially if they're under, say, 5 years old.

threemux··on Ask HN: Airbnb requires my credit-card transaction history?
This is only true if you're traveling solo or with one other person to city centers. Airbnb is far superior for:

* Traveling with young children * Traveling to visit family in rural areas * Traveling for pleasure in rural areas

For example, I can get a house on Airbnb near my extended family in a rural area that has 2-3 bedrooms for a similar price as the 2 rooms that would be required when traveling with my immediate family.

Cross-shopping hotels is useful in some situations, but don't pretend Airbnb has no advantages.
