@patrickleavy has started a petition:

Behavioural metadata extraction underpins the 'surveillance business model'... We think it [enables] manipulation of individual voting at scale via social media microtargeting, spreading fake news, increasing big tech power, mistrust of govs, opinion polarisation, victimisation. RTB system data can be accessed by anyone, not just advertisers (as reported by ICCL)!

Might be a good one to add your name to? Let get the numbers up!

"This project exploits the fact that IDA decompiler fails when it encounters a stack access on a pointer that's too big."

Just spent ~an hour figuring out why a code path wasn't hit.

Turns out it was, only my log messages were configured to a level too low to appear...

Of all the #StarTrekProdigy memes I’ve seen, this one hits the hardest for me.

Validating Leaked Passwords with k-Anonymity - from #CloudFlare blog, 2018:

https://blog.cloudflare.com/validating-leaked-passwords-with-k-anonymity/

This is an important bit in the #Cloudflare post (emphasis mine):

"Our data analysis focuses on traffic from Internet properties on Cloudflare’s free plan, which *includes leaked credentials detection as a built-in feature.*"

We have released the files for the research that led to CVE-2024-36904. It contains the codes, the original kernel source, the patch and the modified kernel source that help to trigger the KASAN splat. If you want to play with the vulnerability, you can use the files.

There's another Office "intentional crash" detected by @expmon_ (background for the 1st one: https://www.linkedin.com/posts/haifeili_if-you-need-a-real-world-office-sample-triggering-activity-7304034115706597376-eVnM), it's a bit different (as I just quickly analyzed) but I'd like to leave it to anyone who is interested in investigating. :)

https://pub.expmon.com/analysis/254228/

So, Cloudflare analyzed passwords people are using to log in to sites they protect and discovered lots of re-use.

Let me put the important words in uppercase.

Question to the Fediverse:

I'm looking for a mailing list / newsgroup solution (it can be SaaS or self hosted).

I need a couple things:
- Easy subscribe and unsubscribe functions
- Ability to send out mass emails to subscribers (basic functionality)

- Most important... and this is the weird part... I need all the subscribers to be able to "reply all" or to email the list as a whole, to also send messages to everyone. But I don't want them to be able to see everyone on the list.

I need an oldschool mailing list proper, where people can track the threads and replies, right.

All the marketing email lists are only top-down - the emailer mails all the recipients, but there is no allowing the recipients to email each other.

The best I have found is GNU MailMain: https://www.gnu.org/software/mailman/

Does anyone know any other examples?

Edit to add better nomenclature (my brain is not forming words right now):
- Allows for email discussion
- Allows for email threading
- Email Newsgroup - that's a good one
