They did do one agent per code chunk, yes. But key is that their agent had to identify when there was a vulnerability and when there wasn't. This "small model" test only had to label the known positive cases as positive -- which any function that simply returns "true" can do. This whole test setup is annoying because it proves nothing.

Mythos was clear it was one agent per chunk. But this positive confirming results do not actually disprove anytime with Mythos, because it is only one side of the discriminator challenge - you got positives, but we do not know your false positive rate and your false negative rate.

This is quite misleading.

If you isolate the positive cases and then ask a tool to label them and it labels them all positive, doesn't prove anything. This is a one-sided test and it is really easy to write a tool that passes it -- just return always true!

You need to test your tool on both positive and negative cases and check if it is accurate on both.

If you don't, you could end up with hundreds or thousands of false positives when using this on real-world samples.

The real test is to use it to find new real bugs in the midst of a large code base.

I don't get the point of banning specific pornography niches/fetishes that are otherwise legal.

Are there not much more objectionable fetishes than this one?

Could be like astrophotography. Where you focus long enough that the background noise cancels out.

Yeah, this Ghost Murmur thing doesn't seem to hold water. But I figured I'd post it anyways, maybe someone know more than me about this field.

Also, I agreed that there was a failed raid, I tried to post on it yesterday but got no traction:

Disney is also a target? Or are you confusing Warner Bros Discovery with Disney?

bhouston — Tue, 31 Mar 2026 14:29:04 +0000

FreeCAD is amazing these days. It has completely replaced my use of Autodesk Fusion 360 for woodworking projects. It is capable and the UI is understandable. Its feature depth is incredible.

FreeCAD is becoming like Blender and Inkspace - incredibly robust and capable and equivalent in most cases to the commercial alternatives.

I find the rendering side of things under developed though.

I immediately go to these two thoughts:

- Is significant life-long usage of real-time mental spatial navigation protective?

- Are those who end up in these positions self-selected for better than average real-time mental spatial navigation and that above average performance correlates with protection against Alzheimer's.
