I do believe that vendor-interoperable SIP exists today, but I also know that I can't call >99.9..9% of the people in the world via SIP, and 100% of the ones I practically do call. This is a very different story from e.g. email – ev

Sure, in a way SIP is bigger than ever with NGNs, and there’s SIP use beyond that too, but actual interoperable SIP (as in, I can dial sip:name@example.com) is effectively not a thing anymore.

Last time I looked at their web client, it was indeed doing absurd things (I think it used TCP and web sockets to carry video instead of WebRTC and shipped a WASM video codec that obviously can’t be GPU/hardware accelerated). Not sure

It’s a real shame that essentially all modern communication other than email runs over proprietary protocols.

Increasingly less so. 2G to 3G was a very clear cut on the radio side (TDMA to CDMA); 4G changed both the radio side (OFDMA) and the core (no more circuit switching, more Internet-standards-like). 5G is already much less clear: 5G non-SA li

That’s most likely because of the massive amounts of midband spectrum that became available for 5G use in the US and less so due to any inherent advantage of 5G.

More likely, data usage has increased greatly in your area since 3G was still available and your carriers spectrum or backhaul hasn’t caught up. 4G/5G make things more efficient but ultimately can’t fight physics.

by lxgr 4d ago
The difference between 4G and (non-SA) 5G is fairly small compared to earlier generations. They use the same core network, and it’s actually quite possible to be connected to 4G and still see the 5G logo. These tricks are less common in Ger

Did they do so by looking at inference prompts against their explicit promises, or maybe just because somebody tipped them off about his unpublished work? If it's not the former, while certainly concerning, I don't see how that&#x

"I took a real photo of this image printed on paper" seems possible to falsify, yeah, but that doesn't seem too surprising to me, given that anyone with a printer can print literally any possible image.

A faster engine is still very useful in practice, for example for position evaluations in game review. Not that an engine evaluation will always be helpful (the line in question making a position strong or weak might be effectively unplayab

It also sounds pretty useful for anyone involved in a lawsuit to be able to present photographic evidence again. I’m sure GenAI is already a big headache for forensics, and enforcing AI watermarks will clearly not be bulletproof.
