Do you have a source for that?

Neither the release post, nor the model card seems to indicate anything like this?

Everyone talked about the marketing stunt that was Anthropic's gated Mythos model with an 83% result on CyberGym. OpenAI just dropped GPT 5.5, which scores 82% and is open for anybody to use.

I recommend anybody in offensive/defensive cybersecurity to experiment with this. This is the real data point we needed - without the hype!

Never thought I'd say this but OpenAI is the 'open' option again.

Not the same league as McKinsey, but I like to point to this presentation to show the effects of a (vibe coded) prompt injection vulnerability:

> [...] we also exploit the embodied AI agent in the robots, performing prompt injection and achieve root-level remote code execution.

Funny, I was just configuring ghostty. I finally made the jump in order to get rid of tmux as a layer of indirection.

Here's what I landed on: This config tries to emulate as much of tmux with native ghostty features (splits and tabs).

Ask HN: Curiosity-driven Business-adjacent Podcast Recommendations like Metamuse

jfkimmes — Mon, 19 Feb 2024 15:17:54 +0000

I really enjoyed the concept of the Metamuse podcast. It brought a few unique concepts together that made it really special, in my mind. It had a very similar appeal to me, as HN has -- for all the same reasons.

Their range of topics was coherent enough to keep me interested, but also diverse enough to allow me to learn about completely new perspectives. They covered everything from their business approach, to novel technologies, to creativity techniques.

The hosts, Mark McGranaghan and Adam Wiggins, are both highly knowledgeable and experienced as entrepreneurs and as engineers. On top of that, they were able to secure some fascinating people and renowned experts as guests.

This combination made for highly insightful but casual conversations that felt very much open-ended and driven mainly by curiosity.

Overall, I found their shows to be very mentally stimulating and satisfying to listen to.

Unfortunately, they stopped producing new episodes after their downsizing, recently.

Are there similar shows that you can recommend?

There's now also https://github.com/vector-im/element-call.

They have SFU support as of recently, so it should scale similarly to Jitsi et al.

Fully agree. But instead of having "the government have full control over people's money", I think, setting this up as a federated cheap-to-run payment system would be even better. This would allow multiple existing banks to offer the service to their existing customers. This could reduce the risk of a fully decentralized solution a little bit.

It's private for the user. Transactions are only between you and the merchant. Credit card networks, PayPal, etc are all third parties with insight into all Payments going through them globally.

It's offline. Neither you nor the merchant have to have a connection to the bank for the transaction to happen.

Usually, in the context of these privacy-preserving payment systems, online vs offline refers to whether the merchant has to be online to check if the 'coin' they received is valid (authentic and not doubly spent). The user usually has no reason to be online at all, since they withdrew the coin already in the past.

By that definition neither the wallet holder nor the merchant would have to be online for a real 'offline' system.

GNU Taler e.g. is an online system on the other hand, where the merchant has to be online for pragmatic reasons. It's kind of sad to see them being categorically excluded by this requirement. Their the best we currently have afaik.

Chaum designed and tried to commercialize an anonymous + offline payment system in the 90s already.

Basically he used (and invented) blind signatures to allow the bank to sign a 'coin' without knowing what they signed. The customer takes the blindly signed coins from the bank, pays at a merchant and later the merchant deposits the coins at the bank again, where the signature is checked.

In this context offline just means that the merchant can verify the authenticity of the coin without immediately needing a connection to the bank. At some point in the future, however, the merchant will have to connect to the bank to get their money. Check out his original paper for details[1].

Offline systems have drawbacks, though. E.g the GNU Taler people made the pragmatic decision to have an online system. See chapter 1.2.1 'Offline vs Online' of Florian Dold's Phd thesis for a discussion on why[2].

Just be aware that your pipeline prompt should not contain any secrets and you should expect that users will be able to subvert your pipeline prompt! I think the most popular name for these attacks is currently 'prompt injection'.

Cool to see that not only the product but also an organization is planned. 8 full-time employees is an ambitious goal. Do you have plans for financing other than donations?

New comment by jfkimmes in "One Year with the Framework Laptop and NixOS"

jfkimmes — Wed, 07 Sep 2022 11:24:06 +0000

I'm in the same situation as the author and I cannot agree more with this statement:

> The Framework is… a pretty good laptop! Frankly, for the first model from a brand new company, Framework did an astounding job of feeling like your everyday consumer electronics seller. Pre-ordering opened up quick, shipped soon thereafter, and there weren’t any hiccups.

I was definitely impressed of how well everything worked, from shipping the laptop to build quality. It is a very fun device to use.

In case the author reads here:

> I sure wish Framework provided fwupd support! I have yet to update my BIOS because I’d prefer to use fwupd rather than create a mess with my bootloader.

There is an image for the most recent BIOS upgrade in LVFS-Testing [1].

New comment by jfkimmes in "Non-Obvious Docker Uses"

jfkimmes — Mon, 25 Jul 2022 07:36:56 +0000

I toyed with a similar setup recently and I had the problem that I, too, would have rules depend on a "docker build"-step (like `docker-image` in your example). Usually `make` would stop building the dependency for non-PHONY targets if it finds the correct file but in this case it obviously cannot find anything.

I tried `touch`ing hidden files for each step and then add those as a dependency but that is not very elegant. Do you have this problem at all?
