Happy to welcome two new orange mayhems into our home.

Fascinating to see the Times slowly trying to come to grips with the way theyโ€™ve been played by Moscow.

It takes them seven paragraphs to get to the fact that the allegations against Biden were (passive voice) โ€œmade up.โ€

Not till paragraph twelve does the real protagonist appear: Russian intelligence. Itโ€™s a Russian disinformation operation. Letโ€™s see if we can say that out loud. https://masto.ai/@Nonilex/111984017335877297

Two years ago, Putin started a full-scale invasion of Ukraine.

Some predicted that it would fall in a matter of days.

Instead, the Ukrainian people have proven the power of fighting for something.

Putin made a mistake because he cannot understand what drives a human spirit when it is free to think and dream.

He cannot understand that if you give people a choice, they choose liberty.โ€ฏ

Ukraine chose to fight for its freedom and a better future.

And Europe will be with you.

North Korea has been supplying Putin with missiles to attack Ukraine. But when wreckage from one of those North Korean missiles was examined, investigators discovered it had been built primarily from smuggled American parts:

"75 percent of the components documented were linked to U.S. companies, with 16 percent linked to European ones, and nine percent connected with companies based in Asia."

So, this is fun, but it really chews through your ChatGPT credits. :`)

I'm working on b4 "code review" mode (grab a series, apply it to your tree, review every patch, send all your acked-by's, reviewed-by's, and individual comments as a one lump batch at the end of your review). The reason I'm playing with this is to see if we can plug in some AI pre-analysis and discussion summaries before the reviewer starts their work.

I look forward to not having to spend a chunk of my day adding spam instances to the MRF policy. เฒ _เฒ

MASSIVE - Hunter Biden โ€œstar witnessโ€ admitted to DOJ that he was getting information from the Kremlin and serving as a conduit for Russian disinfo.

Thatโ€™s right.

Looks like the whole Hunter Biden โ€œscandalโ€ was a Russian psy-op โ€” straight from Putin.

When a site forces you to register, and then tries to spam you, lovingly addressing you by that username you picked in the heat of the moment.

You know how young children will see some toy or shiny object on a store shelf, and somehow โ€” by design! Marketers know what theyโ€™re doing! โ€” they instantly โ€ขhaveโ€ข to have it, and are obsessed, and all sense and proportion go out they window and they need it now now NOW, but if they get it they soon abandon it because itโ€™s junk that only looked good on the shelf?

Itโ€™s like that with CEOs and AI right now.

I just marked my linux kernel mails management tool as v1 (https://sjp38.github.io/post/hackermail_v1/). I hope it answers the questions on my mails management workflow, better than I did in the past.

To help clear up some confusion:

DKIM and DMARC were not created to combat email spam, they were created to combat phishing. In fact, it is very easy for spammers to send DMARC-compliant mail via a spammer botnet, with a valid DKIM signature from Gmail (or any other large provider):

1. a spammer registers an account at gmail.com and sends a single spammy message to another Gmail account they control

2. they download that message, with all the headers, from their other account

3. they then send this same unaltered message to thousands of addresses via their spam botnet using a different envelope-from domain that has valid SPF entries matching the botnet

4. The spam email arrives 100% DMARC-compliant, because the SPF records matched the envelope-from domain and the DKIM signature matched gmail.com in the From: header

Google is fully aware of this, but they can't do anything to stop spammers from using this scheme -- at least not yet. They are pushing for "Replay-Resistant ARC" (https://datatracker.ietf.org/doc/draft-chuang-replay-resistant-arc/), which is why you will see a "darn=" header in the DKIM signature you get from gmail. However, even if they succeed in getting it adopted, we're still easily years away from it making any kind of impact on spam.

FYI, the Fedi spam problem is only starting out. It won't take much effort for someone to write a payload running on random compromised webservers to send copious amounts of spam via activitypub, making blocklists ineffective.

We will basically need to implement all the same anti-abuse stuff we're already doing for email in order to cope with it on the fediverse -- greylisting, dnsbl, domain authentication, etc.

Sadly, the only way this won't happen is if ActivityPub stays sufficiently niche to make other targets more popular for spammers.

In the face of hundreds of thousands murdered in Ukraine, and millions more displaced fleeing Russian military aggression, it is hard to focus on the death of one man. And yet, Navalny meant a lot to the Russian opposition and his death is just another proof that Putin's regime is criminal to the core and cannot be dealt with by appeasement or backroom deals. Ukrainians are the only force actively fighting the Kremlin mafia regime and we should continue to give them all they need to achieve a swift and decisive victory.

b4-0.13.0 is now available!

This is a quality-of-life release that improves on many features but doesn't add any new major functionality (yet).
