This is technically true, and nobody contested the CABF's focus on HTTPS TLS. However, eventually, the CABF started imposing restrictions on the public CA operators regarding the issuance of non-HTTPS certificates. Nominally, the CAs a

Let's Encrypt also provides value by providing signed TLS certificates that are enrolled in all major operating systems, and that can be used to authenticate any TLS server. This is a significant and important use case that's tota

The public TLS PKI was never supposed to serve every use case and you know it. But let me point out when it was possible to get a public CA certificate for an XMPP server with SRVname and xmppAddr: Certificate: Data: Ver

Yes, this is what is happening. It isn't happening fast enough, so some implementations (especially servers that don't upgrade often enough, or running long-term-support OS flavors) will still be affected. This is the impact that

Can you point out, at which point in time exactly, the public TLS PKI infrastructure has been reduced to WebPKI?

A federated ecosystem of servers that need to verify each other based on their domain name as the identity is the prime use-case for a public CA to issue domain-verified client certificates. XMPP happens to be this ecosystem. Rolling out a

It is really great how they write "TLS use cases" and in fact mean HTTPS use cases. CA/Browser Forum has disallowed the issuance of server certificates that make use of the SRVName [0] subjectAltName type, which obviously wa

The interop was a nice feature implemented by their engineers, but it violated the lock-in operational principles of the gatekeeper services, so it had to be abandoned. Let's see if the EU Digital Markets Act will bring back XMPP inter

Yeah, I've documented a thing or two about the NX series on https://op-co.de/blog/tags/samsung-nx/ Regarding the RTOS, I took my NX300 from the shelf some weeks ago to make a few shots for the live demo

The other half of the problem is what to gain from a root shell. You can't influence the stages of the image processing without a PhD in Sony DSP Reverse Engineering, and so what remains is probably hooking into the camera controls and

The last two generations of Samsung NX cameras were built around Tizen Linux, and it was (and still is) easy to get a root shell on them. They still make great photos and you still can buy them used for a good price. NX300/NX30/NX

Looks like it was invented by two Fujitsu engineers, is free of patents and maybe was optimized for hardware implementation? I've linked some Japanese sources in the post, but I don't speak Japanese and the auto translation is not

Creating a high performance image processing pipeline requires significant engineering effort and probably a custom SoC or DSP. You need to take care of auto focus and all the other physical configurations (shutter time, aperture, ISO), the

I'm a huge fan of the NX mini and they are fully supported by the SNS API bridge. I have a bunch of them, one converted to infrared. Usually I have the mini with me when the NX500 is too bulky. It's a pity that the lenses are so r

They only have absurdly high resolution. The optical quality is rather mediocre if you need to zoom or shoot in low light.
