Route48, OAuth,Email, CPU, HSM, Matrix

1. Route48 (@ route48.org) is a IPv6 tunnel broker. It provides IPv6 tunneling using VPN technology WireGuard / ZeroTier and also for networking pros BGP, 6in4, SIT, GRE, rDNS, AOL, ASN and works even behind due the VPN tech. Pretty awesome. It's just interesting to see, if it can survive, there have been many tunnel brokers which come and go for various reasons.

2. Long long discussion again about OAuth (@ Wikipedia) vs JWT (@ Wikipedia) vs basic access authentication (@ Wikipedia). None of those sign or authenticate the data / request itself. And some are just overly complicated. As well as any authentication token, in header will work. Or the authentication header can be cryptographic depending on payload, so it's even better than having just access token.  Well, this is one of the cases which can be implemented in so many ways, whatever is preferred. Or just use client certificates (@ Wikipedia). Also related to never ending password discussion, which is demonized by people, whom clearly don't know or understand the topic.

3. ISP(Telia)  announced that they're terminating support for all email services. Not really unexpected.

4. Intel vs AMD - It came as huge surprise how big performance difference there is between Intel Gold and AMD EPYC processors. Intel seems to be around three times faster than AMD EPYC. Single thread benchmark result: AMD EPYC 7542 32-Core Processor: 1288 vs Intel(R) Xeon(R) Gold 6136: 3643. That's almost 3x difference. But this is synthetic benchmark result. The real world practical production results where the data access pattern requires even more RAM access is naturally even worse. The only conclusion from this is that either the CPU cache, pipeline or RAM bus is causing the issues. On paper the processors seem quite comparable and that doesn't explain that difference.

5. Very long discussion with bunch of newbies about benefits and drawbacks of using HSM (@ Wikipedia) / security tokens like / FIDO keys. And the classic worries like losing the key and so on.

6. Ah, one obvious thing proven again. Some systems which claim to be anonymous, of course aren't. I just so much knew it. In general terms, we could say there's no news there. It's nice to claim that systems are anonymous, but still many systems do not actually want to provide anonymity after all. So, it's all a big scam.

7. Matrix proposal 1763 for specifying configurable per-room message retention periods (@ GitHub) - Excellent write up to the m.room.retention settings. Also the new settings can specify alternate retention for remote events versus local events and so on. Yet as we see, this proposal has been open for years and it hasn't yet fully manifested with the practical implementations & usage. kw: MSC1763, MSC2228, ephemeral messaging, Matrix, instant messaging, distributed and federated messaging platforms

8. Helped a friend with .dk domains. It's really confusing that the dk-hostmaster.dk shows that domains is expiring, even if it's been renewed with registrar (OVH). - Little confusing details and things, that cause unnecessary stress.

9. Outlook web has been updated with some ultra bad JavaScript code, pinning CPU almost all the time when switching folders, and it does often cause messages to be completely lost by random acts. I'm really wondering what kind of engineers they got, utter and total incompetence of basic things.

10. Something different? - Bistatic sonar & Multistatic sonar (@ Wikipedia), bistatic radar (@ Wikipedia) and Multistatic radar (@ Wikipedia). - HQ-22 / FK-3 (@ Wikipedia) air defense system. kw: passive covert radar
