  • Meshtastic gives you three hops by default (and strongly advises against going beyond that, even if the maximum is seven). The furthest node I see right now is about 200 km away.

    MeshCore gives you 64 hops. They can afford that because MeshCore devices send way less telemetry by default; Meshtastic assumes that you want to broadcast e.g. your GPS position regularly. The furthest node I see right now is about 50 km away.

    By the way, while LoRaWAN is a thing, neither Meshtastic not MeshCore are really designed for data traffic. Owing to the low (and shared) bandwidth, they’re more like IRC over radio.



  • There seems to be more traffic on MeshCore than on Meshtastic, probably due to its greater range. Also, the core library seems to be MIT-licensed.

    Besides, given the goals of Meshtastic/MeshCore (low power long range text communication without a radio license), LoRa is a sensible choice: It operates in appropriate radio bands, is power-efficient, and hardware is readily available at reasonable prices.

    Sure, something like DASH7 would be more open but it’s also much harder to find hardware for. The most ideologically pure stack in the world won’t do anything if there’s not enough users to actually form a mesh.

    WiFi is useless when you’re trying to send messages over long distances without any infrastructure beyond “I tied a few battery-powered transceivers to trees along the way”. It has completely low range and high power draw.

    Packet radio gets you a lot of range but may require a license for legal operation. It also has high power requirements; you’re not going to run your radio setup off a 1000 mAh battery for a week.





  • He has pretty much torched all of the USA’s soft power and standing as a trade partner.

    GWB had already done some damage to both, which Obama tried to repair (more so on the trade front). Then Trump I happened and made it very clear that the USA were no longer a reliable partner and probably not even politically stable in the medium term. Biden tried to salvage something but then Trump II happened and conclusively buried what little goodwill the States had left.

    I don’t think the pax americana is going to survive the decade and neither is the petrodollar. It remains to be seen whether the States will become a local hegemonial power, a failed empire with lasting ambitions á la Russia, or will even fade from relevancy entirely. I don’t expect them to remain a superpower.





  • It typically doesn’t. Most countries don’t care about where your ancestors came from. Being fluent in the local language and culture will generally give you a leg up if you already qualify for immigration so I hope your family kept those alive (and not Americanized versions like Irish-Americans wearing green on St. Patrick’s Day). But your ancestry is usually completely irrelevant.

    Those genetic test results absolutely don’t mean anything. If you’re culturally American with an American passport, you’re American and that’s it.

    And due to social media dominance, the far-right party (AfD) is set to become the strongest power with the next election if things don’t change.

    Mind you, that party has been confirmed to be radical by the constitutional protection agency; that assessment has only been temporarily retracted because they got an injunction against it that now needs to be resolved. Court procedure is the only thing keeping them from being recognized as a threat to the democratic order.

    The other major parties see no reason to comment on this, especially not the conservatives. Those same conservatives refuse to rule out a cooperation with the AfD, instead wanting to “face them on content”. That means parroting their talking points and then acting surprised when this doesn’t drive voters away from them.

    In previous elections I voted for the pan-Europeans who, in a saner world, would be steadily on track towards beating the 5% cutoff. Unfortunately, right now the far-right threat is too big for me not to hold my nose and vote strategically. I’m not happy about that.

    But hey, who knows how long that’ll even matter? Like always in such a situation, I expect the AfD to use bullshit delay tactics to stretch that injunction until after the next election, get voted into power, and then kill the investigation. Because rules don’t apply when you have enough backing. And I’m deeply afraid of what they’ll do to the country as the governing party with a conservative lapdog rubber-stamping everything they say.




  • To put in context how much they are driving up demand: OpenAI just bought 40% of the global wafer production from two of the three major RAM manufacturers, Samsung and SK Hynix. SK Hynix Micron (best known for their Crucial brand) decided to drop out of the consumer market entirely.

    Of course the other AI companies are going to try to nail down supply as well. If they get similar deals, 10 € per GB of DDR5 will look cheap.

    This will increase the cost of computers, phones, and laptops, both directly and indirectly (e.g. GPUs will also become more expensive; VRAM doesn’t grow on trees). We’re already at a point where Samsung Semiconductors reportedly refused to sell RAM to Samsung Electronics. I fear we might enter into an age of 2000 € basic office PCs and 1000 € mid-tier phones if the AI bubble won’t pop first. Even when it does, the repercussions will be felt for some time.


  • Except if they then have to run it on their machine and the setup instructions start with setting up a venv. I find that a lot of Python software in the ML realm makes no effort to isolate the end user from the complexities of the platform. At best you get a setup script that may or may not create a working venv without manual intervention, usually the latter. It might be more of a Torch issue than a Python one but it still means spending a lot of time messing with the Python environment to get things running.

    This may color my perception but the parts of the Python ecosystem I get exposed to as an end user these days feel very hacky. (Not all of it is, though; I remember from my Gentoo days that Portage was rock solid.)
