Yes. And that requires the participants to self-regulate and be educated, at least beyond a certain number of participants (and this number is more in the 100's than 1000's of devices in a city size area).

In case anyone is interested, in meshtastic, for a regular handheld device, set it to client if in a less populated area, client_mute in densely populated areas. router/repeater only for really well positioned nodes (think top of a mountain, NOT top of a tall building), router_late for ok positioned nodes where there's other, better router nodes around, but they can cover some dead zone that the better router ones don't cover. And then there's other like client_base for e.g. a rooftop node to help handheld devices inside the house reach outside. And follow the guidelines of your local area group/forum/whatever on number of hops, band to use etc.

None of that is really complicated, but a lot of users will just buy a device, turn it on excitedly with default settings, see that messaging works and not dig deeper, and then worsen then network for everyone.

With meshcore, there's a repeater firmware and a client firmware, it's not just a setting that can be selected in the app. Default is client, and switching to repeater mean reflashing the firmware. And more clients don't really matter for the network, since they don't repeat. So much less risk of an unwitting user worsening the network.

And if anyone wants to play with this, all the devices should support both meshtastic and meshcore firmware, so you can play with both and see which you prefer.

And if you're curious why I prefer meshcore, these are all the nodes I was able to hear on meshtastic and meshcore, respectively, in the same location, with meshcore I can reach twice as far in each direction

I'm definitely not an expert radio operator or anything, but this is how I understood it.

With Meshtastic, no, it actually gets worse beyond a certain point, especially in dense areas. Each radio rebroadcasts messages, so more message fill the air, causing more congestion. setting devices to client_mute (no rebroadcasting of messages) alleviates this to some extent, but most people don't do that. In general, a few well placed nodes are better than a lot of clients.

Meshcore with dedicated Repeater nodes alleviates that a bit, as a node is either a client that can originate messages, or a Repeater that can only rebroadcast. And it has a bit better routing protocol, reducing unnecessary duplicates in some cases.

The radio band is license free in many countries, but there's still some restriction, e.g. 10% duty cycle in my country, which means no radio can be sending more than 10% of the time (so 1 minute in every 10 minute window). That combined with (afaik) nodes only being able so send one message at a time limits how many messages can be in flight at an instant. And more clients increases background chatter from e.g. node announcements and duplicates, leading to further congestion. And in meshtastic, since packets "flood" out in all directions, and each node rebroadcasts again, and it's not directional, all the packets travel all over the place when you send a message. You could have a packet traveling in circles between new nodes for a long time.

E.g. in my region, originally the default for meshtastic was 7 hops on long range fast preset. That led to congestion so they switched to medium range fast, then recommended limiting hops to 5, and now ideally to 3, just so there's less chatter and less utilisation of the channel. 3 hops is barely enough for me to get out of the city I live in. Meshcore also does floods, but also can keep track of paths so you can have a relayed connection along a specific path that does not flood out in all directions, along with putting up repeaters being a conscious and strategic choice by users, so you get something more like a dedicated highway of repeaters that are placed high up and can relay messages much better than some client down at street level could. And the hop limit is more like 64 (I think it can be higher but that's what is set somewhere in the firmware). And repeaters are stationary, so they don't need to announce themselves to the network that often (e.g. every 3 hours in meshtastic vs every 24-48 hours in mesh core). All of that means less channel utilization and longer reach.

I agree, that would be amazing. I also hope it will help with some truly local community building (no troll farms from halfway across the planet spamming shit). Weather stations are already possible with sensor nodes, and most big repeaters have weather data. Though not like weather forecasts or anything.

The main issue would probably just be congestion, not even bandwidth. Once it's used a lot, some packets will just be dropped due to congestion and you don't get a reply at all.

A bit less of a problem with meshcore, with meshtastic in densely populated areas most users still don't set their devices to client_mute, causing unnecessary rebroadcasts and even more congestion. Though with enough adoptions maybe governments might lower their restrictions on duty cycle, allowing for more traffic.

Meshcore might be a bit better suited for this, if you want to reach a forum further than 50-100km away reliably.

With the room servers it almost supports this use case already

Ich dachte ja, erst Venezuela mit dem Öl, das zu aufwändig zu raffinieren ist um profitabel verkauft zu werden bei aktuellen Ölpreisen. Dann Krieg im nahen Osten starten, der die Ölpreise hochtreibt. Aber das wär wohl zu clever für Trump. Anders rum würde es Jahre dauern, die Ölproduktion auszubauen und das wäre viel zu verfrüht, also vielleicht genau das richtige Level an Dummheit?

Wäre so das, was ich erwarte, wenn man Weltpolitik aufgrund von ELI5 Verständnis der Welt macht

Not a democrat or even american, so 🤷

That's not what I'm saying, OP asked an LLM for a legal opinion on what democrats could do. LLMs are terrible at legal questions/opinions. Of the things it says, if they were true and made legal sense, none of it would stop the current war any time soon, it's stuff that would take years to figure out, by which time this likely has blown over for the next crisis.

By all means, prosecute the fucker and his administration for everything and try and make his life hell. But asking an LLM for a legal opinion on what democrats could do seems like top grade cope/virtue signaling so someone can feel better going "see, there's all these things they can do, but they don't, so they're in on it and bad". when there's enough valid reasons to think that about democrats without falling back on slop and there's no shortage of valid criticism, nor valid actions they could take.

What is this LLM slop?

Half the stuff Trump wouldn't care about, the other half would not really affect any current military operation. Plus most of it he'd just ignore like he did most other things, e.g. tarifs are illegal, welp, let me just use some other law to justify tarifs

Thai has some different words and accents used by male and female speakers. best source i could find with a quick search though i'd have liked a more detailed one.

Look at the Tether stablecoin, Tether is solely responsible for minting new tokens and has full control over the tokens, being able to blacklist or destroy wallets/tokens (since it controls the "smart contract" involved). And they have done so because of sanctions and law enforcement request in the past, with afaik well over 1 billion USDT frozen.

I see no reason why the trump team wouldn't just go for the same mechanism for their stablecoin.

I'm not talking about the quality of LLMs (they suck, in so many different ways…).

I'm criticizing the experiment setup, it is not really statistically sound. Doing 10 tests each with 52 different models is almost bound to have one model be correct 100% of the time (even if the true probability is closer to 50%), by pure chance. Doing 100 tests each might yield very different results with none of them answering correct 100% of the time. Or put another way, the p-values of the tests performed are pretty high, not <0.05, so the results don't really say what they purport to say.

Poor guy just wanted to get better at writing/animating

[–] JustTesting@lemmy.hogru.ch 1 points 1 week ago (3 children)

10 tests per model seems like way too little and they should give confidence intervals…

the 10/10 vs. 8/10 is just as likely due chance than any real difference. But some people will definitely use this to justify model choice.

Zweiter Teil in einer Serie über den weltweiten Faschismus heutzutage, der sehr detailliert darauf eingeht, inwiefern der Faschismus von heute sich von früheren Wellen unterscheidet und welche Formen er annimmt. Ziemlich langer Artikel aber lohnt sich meiner Meinung nach, vor allem in Hinsicht auf die aktuelle Situation in Europa.

Folge 1 ist denke ich nicht so relevant, da geht es hauptsächlich um die Situation in der USA und DeSantis vs Trump, deswegen poste ich nur Folge 2.

Und ich teile normalerweise Republik Artikel nicht, ist ein super Magazin und will sie nicht um Einnahmen bringen (zumal man die Artikel ohne Datenklaumauer teilen kann), aber finde den Artikel wichtig genug um eine Ausnahme zu machen.
