From [0], it seems that RCS can use the cellular signal instead of LTE or 5G:
> In cases where RCS is able to operate over cellular networks without data, it supports messaging as well as file transfer, enriched calling, and more.
In LTE and 5G there exists no cellular signal without data. That was a 2G/3G thing. Since 4G everything is data. The separate sms and voice services are gone. And 3G is rapidly being deprecated.
That's not quite true. VoLTE was an optional part of 4G in the beginning. I had one of the gaming ASUS phones that shipped with 4G, but no VoLTE. 6 months after getting it, the US phone carriers conspired to make VoLTE mandatory for connecting to their towers, effectively bricking my device. ASUS never issued the firmware update that would have enabled the feature in the modem, which had the capability, and the community hack to enable it never worked for me.
It was an optional part but without VoLTE you just could not call with 4G. For that the phone just switched back to 2G/3G.
That's not a sustainable solution because 2G/3G are getting switched off. And it doesn't really have any bearing on LTe itself.
The real issue is that they didn't really standardise VoLTE enough. Leaving every carrier and manufacturer to have a mesh of different options and not every carrier and every phone supports the exact same subset of options, which causes the compatibility issue. Also sometimes providers don't bother checking phones they don't sell.
They really should have standardised it 100% so this couldn't happen.
Yes, circuit switched fallback was possible for a time (LTE data and circuit-switched 2G or 3G voice). I think 3GPP shouldn't have written that into the spec in the first place, but you know what they say about hindsight....
It's true that it's all packet-switched rather than circuit-switched, but IMS traffic is still handled differently than regular data traffic. (The most user-visible implication of this is the QCI difference: cellular phone calls are much more reliable at poor signal strength and high congestion than over-the-top VoIP calls).
It's a totally parallel IP stack that's handled differently on the device and the base station hardware. Being on a call will affect what frequency bands your phone uses, handoff behavior, carrier aggregation, and other things that over the top calls like WhatsApp audio wouldn't.
Please correct me if I am mistaken, but unless there’s a local resolver for every single one of your clients, aren’t the DNS requests sent in plaintext to the upstream of your local resolver?
That might not be an issue for your situation, but I recall the benefit of something like Quad9’s offering is the encryption between client and their endpoint(s), particularly for untrusted ISP or similar.
Yes, that's a real benefit in many situations. Everything on your lan can do normal DNS queries to your local forwarder, which talks DNS over TLS or DNS over HTTPS to Quad9.
Downside is Quad9 can see all your DNS traffic. But without it if you run your own recursive resolver your ISP sees all your queries, and many others see portions of them, unencrypted.
I was going to say something similar: invoking one’s credentials as a professor only counts for legitimacy if that 30-year legacy of thinking on the topic is applied to the problem under discussion.
In my opinion, if the analysis is offloaded to the plagiarism machine, it loses all epistemological value.
Not really. 0-based indexing is different from counting and starting with 0 in a counting context is weird. Would you ever say a set has zero elements when it actually contains a single element?
It's a remarkable coincidence that I'm reading the book The Nothing that Is: A Natural History of Zero by Robert Kaplan, and this passage on page 96 seems precisely relevant to this situation:
"""A Roman idiosyncrasy about counting reinforced this
avoidance. The 360 degrees of longitude, for example, were
always measured from the vernal equinox, which lies in the
zodiacal sign of Aries. This should be zero degrees, 0°. It was
common, however, to call it instead 'the first degree', Aries 1°,
as Pliny did around 60 AD, upsetting his calculations and those
of many who followed him. It amounts to this: if you lay out
four marks on the ground and step from the first to the last,
have you taken three paces or four? Clearly three; yet four
marks were involved. To get the right answer it helps to call
the starting-line 'zero'; then the number at the mark you step
on will correspond to the number of your steps. But the Romans
counted so that three days after Sunday was Tuesday; the Italian
for the fifteenth century is the quattrocento — and all of us still
call the two steps in music from C to E a major third, taking
the number from the three tones involved."""
I wouldn't say that the set that has one element, labeled 0, _has_ zero elements; it has one element with the label 0. Right?
This seems simple and utile! Reading though the white paper on GitHub, there is a malformed Markdown table in the “Why WebRTC?” section [1] that probably just needs one more | somewhere.
I’m curious what makes you a supporter, as you say? Supporting the companies that make them or the developers themselves pushing the technology forward or the impacts of the proliferation of the LLMs’ usage or something else?
Transformative implies neither good nor bad. You started this thought in your original comment re social media and how that's now possibly perceived as a net negative, despite the original aims of its inventors.
Is there something someone could hypothetically tell you about how AI/LLMs as a technology might come to be understood as a net negative that would sway your support?
For full disclosure, I sit on the other side of this fence, with a constant concern of the issues that we will see arise. As an exercise, I try to imagine how these issues will be outweighed by the positives, though it's a challenge tbh.
I like this article because it seems to go into decent depth on the “framework” that the author comes up with.
However, this following quote has a simple reason that I don’t see anywhere in the article or framework:
“””
Why is there a huge gap between what people in various occupations could be using AI for and what they’re actually using it for? One reason could be that people are slow to adopt technology, and that’s certainly part of our framework.
“””
I would like to add a reason: that the Silicon Valley companies who developed the LLMs are brigands: cognizant of their actions, they have stolen (and continue to steal) the world’s copyrighted material and are selling it back to the masses and the politicians as if they are the arbiters of information itself.
Specifically responding to the quoted question, I could be using Claude or ChatGPT or Grok or DeepSeek or any other to have come up with this comment, or to write emails, or to implement my Python for me, etc., but I use none of them for anything. Doing business with brigands is a choice, and a choice that I hope becomes less and less palatable so that the financial, political, social, and moral fever that is our zeitgeist finally breaks.
