They will 100% reverse this decision. Surprising it made it past engineering strategy & leadership at a company as large as GM and that they would even float this publicly without the details... but this will be walked back.

How large companies can make it so far and still have such insane decision-making (management by instinct?) is so wild to behold.

I think that'll only happen when and if the corresponding drop in sales offsets increases in revenue from the subscription services owners will be forced to use. When they announced this originally for EVs it was clear the underlying motivation was to convert owners from a one-time source of income into an ongoing stream by forcing them into a subscription model for features they would get from CarPlay/Android Auto.

In my head, one of the things that makes up an "enterprise grade" switch is 48 ports. Because "for the enterprise", in my opinion, evokes some idea of large scale deployment, not a mom and pop trinket store with one PoS cash register device and three company computers.

What does enterprise grade mean to you?

kevvok · 2 months ago

The smaller switches like the Arista 710P are meant for deployment out at the edge of the network where you want something small and quiet (e.g. at people’s desks or in conference rooms) to provide more ports without needing as many runs back to the network core where the big loud switches live. They’re still enterpise grade since they support enterprise features like centralized management, VLANs, QoS, IGMP snooping, etc.

Pretty sure this isn't possible?? There must be some way to use a hash of the clientHello later in the key exchange process to make sure the connection fails if the hello is tampered with...?

Yeah, the ClientHello message(s) are already part of the transcript signed by the server (and the client in mTLS) during the handshake

This reminds me of how Sarah at the Connections Museum in Seattle wrote a driver to allow an Asterisk soft PBX on a Linux box to speak revertive pulse signaling to the pre-DTMF trunks on their old telephone switches

> When the client sends a hello, the firewall says “that looks like a TLS hello”, and then waits for the server’s response. It inspects the certificate and then applies any rules.

This kind of stuff is exactly why TLS 1.3 encrypts everything now.

Years of middleboxes tampering with TCP and barfing on anything they didn’t recognize is why QUIC encrypts everything as well

kevvok commented on O2 VoLTE: locating any customer with a phone call mastdatabase.co.uk/blog/2... · Posted by u/kragniz

Also very curious how the call initiator was able to see the call control messages (ie SIP). Arent all these messages wrapped inside an encrypted GRE tunnel between handset and cell tower (and MME)? Being able to unpick GRE tunnel encryption would be a gigantic hole. Perhaps this only works because the OP is running analysis on their device, but even then I'm surprised that the pre-encryption payload is available.

Many operators do configure the SIP signaling for VoLTE to use an IPsec transport terminated at the P-CSCF, but most (if not all) of them only configure IPsec to provide integrity protection.

Mr. Magoo-ism galore.

Intel had constantly try to bring in visionaries, but failed over and over. With the exception of Jim Keller, Intel was duped into believing in incompetent people. At a critical juncture during the smart-phone revolution it was Mike Bell, a full-on Mr. Magoo. He never did anything after his stint with Intel worth mentioning - he was exposed as a pretender. Eric Kim would be another. Murthy Renduchintala is another. It goes on and on. Also critical was the the failure of an in-house exec named Anand Chandrasekher who completely flubbed the mega-project coop between Intel and Nokia to bring about Moblin OS and create a third phone ecosystem to the marketplace. WHY would Anand be put in charge of such an important effort?????? In Intel's defense, this project was submarined by Nokia's Stephen Elop, who usurped their CEO and left Intel standing at the altar. (Elop was a former Microsoft exec, Microsoft was also working on their foray into smartphones at the time. . very suspicious). XScale was mis-handled, Intel had a working phone with XScale prior to the iPhone being release .. but Intel was afraid of fostering a development community outside of x86 (Balmer once chanted -> developer, developer, developer). My guess is that ultimately, Intel suffers from the Kodak conundrum, i.e. they have probably rejected true visionaries because their ideas would always threaten the sacred cash cows. They have been afraid to innovate at the expense of profit margins (short term thinkers).

> Murthy Renduchintala

He was a joke at Qualcomm before he went to Intel too. That Intel considered snagging him a coup was a consistent source of amusement.
