> People don't need to disclose who they are when submitting things to HN. Companies aren't people. That's one of those things I just don't subscribe to. If you are the CEO of a company and you are engaging in what can only be termed as marketing activities, effectively advertising your company I think you should be up front about that. Otherwise you can no longer see the difference between organic interest in a tech…

Maybe I’m not appreciating your viewpoint because the article nor the comments seem overtly self-promoting to me. I would agree with you if it was a garbage press release with low quality fake comments. Maybe there’s some niche politics that I’m unaware of in the LoRa space that is triggering.

And maybe I'm over protective of HN.

You mean like the one where the CEO (then still anonymously) tried to devalue a point made by a commenter here:

Not that I'm aware of, but their WP talk page is pretty clear about them abusing WP for marketing purposes and that doesn't give them the benefit of the doubt with me when interacting with HN in this way, besides that the initial votes were so fast that I doubt that it was organic. But when dang wakes up I'm sure he'll be able to rule that out or confirm it. For all I know it is all legit but it certainly looked weird. Also note how the CTO nicely disclosed who he was but the CEO did not well after joining the thread until prompted to do so. Which makes me suspect this is a bit more organized than it may seem at first glance, but then again, that's not my call to make.

CTO & co-founder of The Things Network here! I've been working with LoRa for over eight years now, and I keep getting surprised by measurements like this. What started off as "line of sight works" went to a successful "LoRa moon bounce" [0] and now a sea level reception over 830 miles. So, any physics people here care to comment how this works? Is this pure atmospheric refraction or is there something else? [0] https…

Hi. Cool work. For this particular record, could you confirm that this was on 868MHz?

So I know LoRA: Low-Rank Adaptation of Large Language Models and Using LoRA for Efficient Stable Diffusion Fine-Tuning. But from the text, I don't think this is about it? It seems it's this: https://en.wikipedia.org/wiki/LoRa

Correct. It’s a low bandwidth/ long distance RF protocol over specifics bands. It’s also kinda proprietary.

That's right. Microsoft must have used Bing to see if the name was taken, and got no results, when they named their thing LoRA.

Define "internet". LoRA is more like an occasional SMS service than a network connection, so I doubt you could get the average modern 100 MB website to render through it. Would be more practical to get a Starlink dish set up or a directional wifi antenna on both ends, those can do a few km on a good day. Or just you know, use the 4G that is probably there already.

> Or just you know, use the 4G that is probably there already. Yeah... Projects like open WiFi are probably becoming less and less useful, as everybody is carrying 4G/5G modems in their pocket.

At some point I was bullish on LoRA + Gemini or scruttlebutts.

A different, low resolution internet basically. But LoRA is too slow for a lot of things. Too.

Still nice.

I think I don't know 99% of the CEOs posting here, and I also don't need to? In the end similarly as any other employee posting for his company, and disclosure in the post is just fine? Don't get it.

HN is weird in that there is a format for that, which, as a relatively new entrant you may not be aware of, but that's what 'Show HN' is for, so that you know that whoever is posting something is associated with the article. Otherwise you will get to the point where HN is just another advertising medium, only with the ads not labelled as ads.

Is that written somewhere? Maybe just different understandings and expectations.. but for me "Show HN" is about here is my work/project I'm proud of, want to share with the rest of the world, want to have it discussed. For a normal news, even if you are the author of submitting, not sure if that's necessary. "Show HN" is imo not the anti-astroturfing disclosure, and for my expectations I would actually be a bit surprised and sad if a "Show HN" here would have lead me to just this little announcement, and maybe even downvote it :)

There is never any mention of bitrate when talking about LoRa. It's infuriating from someone on the outside. From what I gather, the map says a "SF:12" which means a spread factor of 12, at a bandwidth of 125khz. With a code rate of '1' according to https://www.rfwireless-world.com/calculators/LoRa-Data-Rate-... this means about 292 bits-per-second transmission rate for the packet. But I'm unsure if this is correct.…

Good point. We'll add that to the next post if there is a new record. Also what can be confusing is that the business viable part is even much smaller than the technical viable part. The low power operations is really only at lower SF7 or SF8. And we push our partners and ecosystem to keep the payload as small as possible as every byte counts. It is a completely different way of thinking than WiFi or cellular. Yet I do agree it is presented with the same terms and paradigm and that is confusing.

LoRa vs LoRA. The former is what the link is about which is some cool radio stuff.

You can do a lot with 292 bits per second if you use it well.

This is not entirely accurate. LoRa is a patented RF technology owned by Semtech. LoRaWAN is a standard maintained by the LoRa Alliance (which is not very different from other standards and marketing bodies). The Things Network (founded by @wienke and myself) is a developer community around LoRaWAN and a free to use cloud service intended for R&D and non-commercial use cases.

Please don't astroturf a corporate driven "developer community" > marketing bodies There you go.

What is astroturf? If I Google it I see fake grass.
