bplatta··on OpenAI agent hacked Australian government website, PM says
I'm a little confused as to why these agents are capable of escaping containment. Can someone who has more understanding (or a better guess) of the harness they are running with shed some light?

To establish the premise: as someone who has a fairly good understanding of the token completion mechanics of an LLM, these agents are completion token calls in a loop, producing a "do this now" request which the harness then runs with some standard "call this function" code.

If these agents are enabled with explicit network enabled tools, its trivial to monitor their inputs/outputs. If they are not, you can still lock down network egress on a machine. If _some_ network egress is necessary you can still do network traffic monitoring. I don't see how they couldn't implement some level of monitoring where big red lights start flashing when, say, their eval system was contacting a domain/IP located in Australia, and further categorize that domain as government owned. This all seems very doable - am I mistaken?

And you're telling me all of these companies are failing to do this? Is my understanding naive in some way? This is assuming some good faith of course, I can easily speculate as to the political and corporate incentive. But it seems to me quite risky/negligent.

Currently, my conclusion is that its just (silly until proven wildly dangerous) negligence with the small side effect of being potentially good for business. And potentially company Foobook is then incentivized to get in on the news cycle for marketing purposes and basically guarantees an agent will do something of the sort by running some harness that allows the behavior quite trivially.

My naiveté extends to why there is such concern with "losing control of agents" when the above measures seem so doable. It might take a law but it seems doable.

bplatta··on Why not “Why not WireGuard?” (2020)
I work for a company that provides a product that tries to make IPsec a little easier and I can say like 80-85% of our support burden is helping our customers configure their ASAs, Junipers etc. to talk to our cloud based VPN concentrator/router/app firewall. We basically run people through a checklist [1] and it is non-trivial. IPsec can be a real pain.

bplatta··on If you sell a house these days, the buyer might be a pension fund
Ok, cabal is a strong word and the election stealing/truth hiding is certainly off the rails in my opinion as well.

But here's some perhaps interesting information on top 5 shareholders of largest US banks [1]:

JP Morgan Chase: Blackrock 6.4 Vanguard 4.7 State Street 4.5 Blackrock 2.7 Blackrock 2.5

Bank of America: Berkshire 6.9 Blackrock 5.3 Vanguard 4.5 state street 4.3 Fidelity 2.1

Citigroup: Blackrock 6.1 Vanguard 4.5 State Street 4.2 Fidelity 3.6 Capital world Inv 2.4

Wells Fargo: Berkshire 8.8 Blackrock 5.4 Vanguard 4.5 State street 4.0 Fidelity 3.5

US Bank: Blackrock 7.4 Vanguard 4.5 Fidelity 4.4 State Street 4.4 Berkshire 4.3

So although yes this does go off the rails a bit, not unreasonable to question the (possibly perverse) incentives banks face given their ownership. Book by Eric Posner and Glen Weyl called Radical Markets explores those incentives a bit.

bplatta··on Does Zoom use end-to-end encryption?
This is a bit of shameless plug, but seems relevant as its about providing end to end encryption for Jitsi. My company provides a VPN product (really a full-fledged API driven SDN) that you can plug containers into. So a network edge that supports plugins. We just spun up a Jitsi plugin. All packets run over the encrypted overlay network for VPN clients. We'll post a little blog post on it soon. PM me if it sounds interesting.

bplatta··on Are We Having Too Much Fun?
on the article: I like to wrap up these sorts of treatments into my own simplified cultural causal models, if you will (hopefully my syntax is intuitive).

Invention of telegraph := ~immediacy of information, minimal context -> incredible boon for society! Essentially the beginning of modern technology, dare i say. The ability to CREATE networks as technology! ooo the power of (high bandwidth) networks!

Invention of Television := immediacy of visual information, lots more context, modern entertainment -> oh the theories abound for what this caused. I like to consider televisions pacifying effect on modern society. This subtle lie about what it claims to be: a window in a room. Oh but of course we know much of it is fictitious! But do we? All the more confusing with "reality TV" and, as discussed here, modern news-tainment.

Just some of my thoughts!

meta, on this comment section: I'm a little surprised this article is getting so easily dismissed. Its simply an attempted synthesis and application of media/normative/critical theorists' work. That is, this is philosophical at heart and I appreciate the author's attempt (it brings to mind David Foster Wallace's constant questioning of entertainment and the effect of entertainment's reflexivity). I think many hackernews readers (like myself) are scientifically minded and so this sort of thesis, i.e. not empirically verifiable, can lack the thrust that we want. But that said, I think it provides a valuable ontology for thinking about modern society and provokes some questions that actually may inform my behavior.

Much more difficult to parse out the noise with these types of articles, I grant you.

bplatta··on Stockholder Proposal Regarding a Report on Users Owning the Twitter Platform
The board's statement of opposition pretty cleanly argues against this type of equity overhaul.

That said, I do appreciate the spirit of the proposal. Specifically, how do users that are contributing to the value of the network somehow extract some of that value in real terms? Of course, there's a lot of complexity to that sort of system and the cost of implementing it substantial. But whereas some people are working on architecting that sort of system from the outset as more a technical feat, this tact would get legal momentum that would almost guarantee some sort solution, be it good, bad or more likely, somewhere in between.

bplatta··on Panama Papers Reveal Clinton’s Kremlin Connection
Seem to be 2 camps here: 1. dismiss this as a tenuous connection which stems mainly from the fact that Lobbying firms have many big clients 2. grant this connection deserves some attention and perhaps some explanation

For me, I think the author has some thoughts that are bleeding through . But I don't think its necessarily fair to judge an article mainly on its author's history (though an undeniable factor).

While granting this is the nature of a lobby firm, it does seem odd they would agree to representing Sberbank. We're talking John Podesta (Clinton campaign chairman) -> Tony Podesta (CEO Podesta Group) -> Sberbank (Podesta Group client). Is the latter connection really not cause for suspicion?
