So, if this youtube-dl thing ends up with distributions such as #debian being pressured to remove it, I hope they consider this:

The RIAA would not have brought this action without Google's backing. Google is not a friend of your distribution.

Perhaps your distro should IDK, change its default search engine.

google, privacy, e-mail, from :birdsite: 

Google started editing people's e-mails in GSuite, replacing links with a link through google.com:

This means that Google will track a click on a link *in e-mail* even if you're using an external client.

I am *guessing* this is under the pretext of phishing protection, but it actually *creates* additional phishing risk for text-only clients, since now all links are google.com links.

Having trouble keeping up with news and developments related to #Bitcoin privacy? I write a monthly newsletter to do just that. 🔐📡🔎😎

And here is the September edition. Enjoy!

Bitcoin Optech newsletter #117 is here:

- describes a compiler bug that casts doubt on the safety of secure systems
- explains a technique that can be used to more efficiently verify ECDSA signatures in Bitcoin
- popular Q&A from the Bitcoin StackExchange

I made a flow chart of which #Mastodon posts end up in which timelines!

So, you can see how each instance will have a different local timeline, and even a slightly different federated timeline - and you can see why the federated timeline moves so much faster than the local one, too.

Interesting proposal for a new fee-bumping mechanism: lists.linuxfoundation.org/pipe

Haven't read the mailing list responses, but bitcoin-optech has a nice quick summary: bitcoinops.org/en/newsletters/

It seems to me that this mechanism is a little worse for privacy (it will publicly link UTXOs that are otherwise potentially unlinked), but this seems to be a small consideration. Probably worth that risk in many use-cases, if it mitigates tx-pinning attacks.
