#matthew-green — Public Fediverse posts

🔓 Oh, look! Another #cryptography "wizard" from the ivory tower of academia thinks they can save the world by roasting #Kerberos tickets like marshmallows over a campfire 🔥. Matthew Green, emerging from the cryptographic crypt, offers 1,473 words of ego-stroking drivel about his resume while the rest of us wonder if the true #security threat is death by #boredom. 🥱

As AI agents become ubiquitous, expect the copyright industry to try to turn them against you

One of the many interesting aspects of the new wave of artificial intelligence systems is that with them, copyright has moved from the fringe to centre stage. There are continuing debates about what role copyright should play in the world of generative AI, not to mention various lawsuits asking the courts to rule on that question. Those debates and lawsuits have been about two aspects of AI: […]

I had been afraid something like this had happened. A friend found an announcement on Twitter, but it's a cesspool these days and I never go there any more so it had escaped my notice. Here's the obituary.

"The challenge in storing encrypted backup data is that strong encryption requires strong (or “high entropy”) cryptographic keys and passwords. Since most of us are terrible at selecting, let alone remembering strong passwords, this poses a challenging problem."

This isn't as hard as people seem to think;

What's missing is education, including replacing "password" with "passphrase".

Except when it's integrating third-party search engines so people can search for reaction GIFs in-app;

"Indeed, it no longer feels amusing to see the Telegram organization urge people away from default-encrypted messengers, while refusing to implement essential features that would widely encrypt their own users’ messages. In fact, it’s starting to feel a bit malicious."

"In the Safe Browsing change we have another example of Apple making significant modifications to its privacy infrastructure, largely without publicity or announcement. We have learn about this stuff from the fine print. This approach to privacy issues does users around the world a disservice

It increasingly feels like Apple is two different companies: one that puts the freedom of its users first, and another that treats its users very differently."

Thank you Andrea Horwath and Matthew Green (@MatthewGreenNDP) for standing in solidarity with Jame Mosque in Hamilton,

After the community was shaken by a bomb threat this month.

Islamophobia has only grown in recent years.

We can all do more to stand in solidarity with our neighbours.

We can all do more for a future without hate.
