NASA scheduled a major workshop for early career researchers during the most important week of the Jewish calendar, during two of the most important days of that week and expects me to accept that this was “difficult scheduling conflicts”

That’s what casual antisemitism sounds like

I really dislike how science has started calling almost any fancy computational technique AI. 🧪

The framing of this entire article makes it sound like a benevolent AI independently made these drugs.

That is *pure fantasy*.

Instead: a team of scientists made a machine learning model for a study.

Title: AI designs antibiotics for gonorrhoea and MRSA superbugs
Description: Two new potential drugs have been designed by AI to kill drug-resistant bacteria, in a major Massachusetts Institute of Technology study.

The fate of ordinary Gazans trapped by Israel in a war zone and ordinary Israelis held hostage by Hamas in a war zone will be one and the same.

They are starving.

They are buried beside one another.

They are cast aside by those with power to save them.

For this we weep.

Read this in full.

I'm short: The ADL has fully given up on its mission to fight real antisemitism.

Instead, they are focused on unconditional support towards Israel, including justification of antisemitism if it serves that goal. Plus, working with fascists & antisemitic groups and people.

I spoke with 40+ sources for a look inside the Anti-Defamation League. Here’s some of what I found.

ADL’s gentle response to Elon Musk’s infamous salute was partially driven by his support of Israel. To ADL, that indicated he didn’t have “antisemitic tendencies.” (1/x)

🤖 Always on the lookout for potential net positive uses of “AI”, esp for elderly…but the claims here pissed me right off:

We cannot let the AI take our em dashes away! I also use them all the time—so frustrating how it has become such an indicator of ChatGPT!

I have been using the em dash for about 10 years (I only learned English 13 years ago, for context). I even got a whole book I published before ChatGPT to prove it.

I am not stopping—too useful!

How the hell did we let AI take away the em dash from us. it's a useful punctuation mark but now people are so stupid that society thinks it's exclusively used by chatgpt

This is just a flat out lie and everyone involved is either malicious or incompetent

Screenshot of a dialog from Twitter. It says:

"Messages are now fully encrypted

End-to-end encryption: messages are end-to-end encrypted across all your devices.

State-of-the-art privacy: There's no way for anyone, including X, to read your messages.

Set up a passcode: In order to secure your messages, you'll need to set up a 4-digit passcode."

Ah, to be clear the virtual HSM here is a juicebox implemented version just for testing the code without costly hardware. It doesn’t even attempt any protections. Which one are you talking about?

1

nora @nora.bsky.social · Jun 6

Belatedly! That could indicate either an HSM or a virtual HSM (meant for testing, not secure). The /livez endpoint suggests they're using the code as-is from main. Request timing makes me suspect a virtual HSM, but it's not definitive.

Please do!

nora @nora.bsky.social · Jun 6

It's totally possible! If you find something concrete, definitely let me know. NCC audited the design and code and there were a number of other folks who reviewed, but mistakes happen and this is the first time its being used in production at this kind of scale.

There's a few others out there using it, but with similar misunderstandings. In hindsight, it's probably not well engineered for most developers to not shoot themselves in the foot. But I'd love to see it used well! It's much more efficient than similar things, like WhatsApps HSM setup

Signal ended up doing their own thing, relying heavily on confidential compute (AWS nitro and the like) which I think is less ideal, but to some degree follows the same premise. www.usenix.org/conference/o...

The hope was to carry on the work we did at Signal on Secure Value Recovery, but diversify away from SGX/a singular hardware failure point.

Technology Preview for secure value recovery

At Signal, we want to make privacy simple. From the beginning, we’ve designed Signal so that your information is in your hands rather than ours. Technologies like Signal Protocol secure your messages ...

The organization doesn't exist anymore. We created the protocol, played with the idea of offering it as saas (we run HSMs for people), pitched around, and eventually scrapped it due to minimal interest. Open sourced and published stuff to the world, and mostly I thought that was that until now!

Yes, I know about that theoretical ceremony :) I linked that pdf above, but noone who worked on Juicebox (and developed that ceremony) worked with Twitter to do this, and given they haven't published the results of a ceremony I must assume one never happened (despite it being our intended design)

nora @nora.bsky.social · Jun 6

And I have good reason to suspect those realms using noise are at _best_ are HSMs that haven't gone through a signing ceremony, but much more likely virtualized HSMs

1

nora @nora.bsky.social · Jun 6

I don't know for sure but I strongly suspect they aren't. They use noise for some realms (which points towards HSMs, but not guarantee), but realm-a.x.com and realm-b.x.com don't use noise at all and definitely aren't HSMs. Since they only require 2 realms to recover, basically they don't have HSMs

Do you have evidence that Twitter conducted a ceremony?

I would definitely be curious if there is a protocol bug (so we can fix it), but not quite sure the avenue you're getting at
