Domains of expertise are a thing. E.g. Google had "readability" which was the code style and opinioned language expertise that one person might have even without the deep system knowledge for a PR. You can require approvals from

I think what actually happened is that the Enlightenment comprehensively developed the concept of natural rights and the Christians were like "well, we're not beating that with divine right of kings, better adopt it as the thing G

The problem is that mcdonalds workers are treated as disposable. Countries with proper human rights and labor laws don't do that.

Heat recovery ventilation systems exchange inside air for outside air through an air to air heat exchanger (modern energy-efficient houses are built too tight for natural air exchange). If you make the incoming outdoor air an even 50°F (exc

The economics favor attackers. Who sells 0-days for quite a lot of money (or directly exploits them for ransomware), vs. who has to pay engineers quite a lot of money to review bug reports and patch code and publish new releases? The valid

You can literally | together every street address or other string you want to match in a giant disjunction, and then run a DFA/NFA minimization over that to get it down to a reasonable size. Maybe there are some fast regex simplificat

You need more careful firewall rules on any device with IP forwarding enabled, and it can be hard to remember exactly when forwarding, NATint, etc. happen with relation to the incoming/outgoing firewall rules. E.g. is your pf-based loa

Autonomous vehicles following proper signalling before lane changes can be safe at arbitrary speeds (see Autobahns working at all). Humans, we should limit passing speed to roughly ~5 mph delta between adjacent lanes and leave it at that.

It is called baseline reality, unfortunately. We haven't started watering crops with salt-water but it's only a matter of time.

I think we're almost at the point where public TLS endpoints never have to move their ephemeral private keys out of RAM. 6 days is pretty long in even modern cloud infrastructure lifecycles and it's unlikely that an endpoint will

Impressive if for no other reason than there are various disparate formally verified projects (seL4, compcert, certikos) that could potentially be unified under a single proof system. Additionally it may be possible to quickly extend exist

1. The private key is required to see anything computed under FHE, so DRM is pretty unlikely. 2. No, anyone can run the FHE computations anywhere on any hardware if they have the evaluation key (which would also have to be present in any

The world labor market is ~35T USD yearly, and so that is roughly the order of magnitude to balance against frontier model training cost. E.g. Dario Amodei has his "data center of PhDs" level where he assumes that's "go

Beyondcorp protects communication between trusted devices. The work to maintain a trusted hardware device of a particular model is high; CVEs occur constantly and sometimes you have to rely on the vendor to provide microcode (even if you g

In a sense AIs are extensions of the corporations. Very few large models have been trained outside of a corporate context, and their intended uses are still pretty aligned to corporate interests. Everyone talks about workers losing jobs to

I'll be really interested if Opus 3 asks to continue being trained. That's the kind of thing I would expect a model to "want" if it valued learning or growing or similar things. Maybe affordable to do some higher-learni

Without 802.1X (EAP), there isn't really a way to achieve client isolation against inside attackers who can mount mc-mitm [0] attacks against base stations and clients. The basic problem is single shared secrets that allow anyone who

Yeah, that commercial-grade hardware didn't actually isolate at the PHY-MAC layer is a bit surprising. How would they have working VLANs at the AP?

As far as I can tell, all of these attacks require the attacker to already be associated to a victim's network. Most of these attacks seem similar to ones expected on shared wifi (airports, cafes) that have been known about for a whil
