> This means Vector databases, Search Indexes or fancy "AI Search Databases" would be required on a per user basis or track the access rights along with the content, which is infeasible and does not scale.

I don't understand why you think tracking user access rights would be infeasible and would not scale. There is a query. You search for matching documents in your vector database / index. Once you have found the potentially relevant list of documents you check which ones can the current user access. You only pass the ones over to the LLM which the user can see.

This is very similar to how banks provide phone based services. The operator on the other side of the line can only see your account details once you have authenticated yourself. They can't accidentally tell you someone else's account balance, because they themselves don't have access to it unless they typed in all the information you provide them to authenticate yourself. You can't trick the operator to provide you with someone else's account balance because they can't see the account balance of anyone without authenticating first.

Let's say you have 100000 documents in your index that match your query but only 10 of them the user has access to:

A basic implementation will return the top, let's say 1000, documents and then do the more expensive access check on each of them. Most of the time, you've now eliminated all of your search results.

Your search must be access aware to do a reasonable job of pre-filtering the content to documents the user has access to, at which point you then can apply post-filtering with the "100% sure" access check.

Do the customers know what they actually need?

Well if you don’t have a pretty good idea of the problem you’re solving for the customer, you’re much better off trying as many things as you can, quickly and cheaply, to figure out.

That's not how you build big important, expensive things, though. It all depends on the context.
doomslice · a year ago
Do you know that the big expensive thing is what your customers actually need? Do you actually know what your customers need?

That’s basically the only important context. If you can’t deliver that, it doesn’t matter how well thought through, extensible, or scalable it is.

> Unfortunately, at this point, this research does not include actual code that we can use to reproduce the claims or the effectiveness and accuracy of the described side-channel attack.

So this is just a marketing op-ed?

Did they remove it? It says the researchers provided a notebook that they used to verify the attack.

How do you know that? You can't because Dropbox doesn't say

If you click the setting to 'off' you are making the assumption that your stated desire will be honored and that there won't be another move like that in the future. The better move would be to stop using Dropbox, that way you are really sure that your files won't be accessed by unauthorized parties.

I really don't get what drives companies like Dropbox to throw their carefully built up reputation under the bus like this.

All this setting does is make the feature available to you in the frontend -- it's up to you to use it or not!
doomslice commented on Google changed ad auctions, raising prices 15%, witness says   finance.yahoo.com/news/go... · Posted by u/mikerg87
Retric · 2 years ago
There’s two common kinds of auction those with multiple rounds where the final bid wins and those where everyone puts in the maximum amount upfront and the winner pays whatever #2 bid. The second type is much faster but incentivizes the auction house to lie about the #2 bid.

Google did the second type and then got caught lying about bids. Doing so is really tempting but also generally fraud.

In adtech a first price auction is also a single round.

My man…if only you knew

6 years ago an intern in chromeOS using Gem5 found an optimization in how Android’s ART emits code that would help all in-order arm cores(a-5x) to the tune of 10%. A simple fix. He prototyped it. It worked. Fix was a dozen lines. It never shipped…

You gotta save that optimization for when performance ends up on a top level OKR!

There are many examples of Google's automated systems making egregious mistakes while scanning user data with no human in the loop to review the decision.

>Ed Francis studies the evolution of military technology over at his YouTube channel, Armoured Archives. But this week, Francis says five years’ worth of research stored on Google Drive has become inaccessible thanks to Google’s automated error.

Francis says the file in question was simply a collection of data on various tanks for a coming video on how military vehicles have evolved across historical conflicts. But Google’s automated systems deemed the file a terrorist threat, resulting in a complete lockdown of his YouTube, GMail, and Google Drive accounts.

Having a shitty algorithm kill your whole Google account with no way to reach a human to fix the problem is one thing.

Having a shitty algorithm report you to the police for taking pictures of your child's first bath is a bridge too far.

I'm not defending this at all, but one of the reasons why there are no (or few) humans that can be contacted is that they* said that it was tried before and it caused a lot more issues with mistakes/takeovers due to social engineering.

* Can't remember who said it but it was at a town hall this year
