I think it's entirely fair to say that their post essentially summarizes as "what we currently have is probably not enough" and ends in an implied "maybe we need more [though I would personally rankle at it]". So in some ways they did.

But yes, I agree: they do not actually suggest any new restrictions, and I did not mean to imply that they did. I just meant to head off the obvious rebuttals, and make my stance clear: you cannot have "allow the knowledgeable to do X" and "prevent the un-knowledgeable from doing X" in the presence of social engineering at a technical level, and there is ample evidence that more popups and friction are not an effective solution. So a safe default and reasonably-ergonomic-but-not-accidentally-trigger-able ways around it seems roughly ideal IMO.

I think OSX hits that balance fairly well: block by default, right-click -> open to bypass individually (arguably accidental-able, but odd enough compared to double-click and there is still a clear warning displayed), or change settings to allow by default. It's both effective and friendly, and going further in either direction seems like it requires major sacrifices in the other. And when you do want those sacrifices, you can get them (non-admin account or disable it entirely).

This is awesome.

Less dramatically, when I lived in Germany, where I had radiators for heat, I stored baby bottles of water on top of the kitchen radiator. It kept the water the perfect temperature for my infant with zero risk of it being too hot, so zero risk of scalding. All I had to do was add powdered formula when he got hungry.
> The war itself is illegal

Yes, Russia's invasion of Ukraine is illegal. It's a war of choice waged for reason no better than Putin's vanity. It hasn't helped Russia and it certainly hasn't helped Ukraine.

Fortunately, it is within Russia's power to end the war tomorrow. All Russia needs to do is leave Ukrainian territory, return relocated Ukrainian citizens, start paying reparations, and begin the process of extraditing war criminals so they can be tried.
Can a legal-hold require you to wear a wire 24/7 and record everything you say? Can they require that you do not speak in person to anyone else at your company unless it is by email, and each email is cc’d to Epic Games?

Those would be my naive tests for whether a judge can require you to use instant-messaging with permanent history over ephemeral history.

Edit: my armchair lawyering doesn’t add nearly as much to this discussion as the other responses here.

Deliberately going on record as saying “let’s hook the email printer up to the auto shredder and claim innocence winking-smiley-emoji” when a judge has told you not to is indeed the kind of behaviour of which a court should take a very dim view.

Didn't test SantaCoder or the salesforce models.

Would be interesting to see how they do.
I tend to agree. However, turning them off is partially exactly getting the act together.

The very big problem is that at the same time particularly southern German states fail to support renewables and power distribution lines.

So while there was a time line. One part of the time line was missed. So everyone decided to rather count on Russian gas as an intermediary solution with the known geopolitical consequences that followed.

PS: Strange twist: There is a German company that now wants to produce fuel elements for Russian nuclear power plants...
I haven't made any extraordinary claims.

> Red Hat created an industry and all of the successful enterprise Linux distros have followed its model to some extent or another (Canonical, SUSE, etc)

IBM created that industry, by lifting Linux into their supported platforms portfolio.

and the first Enterprise Linux ever was suse linux enterprise for s/390, followed by x86 releases at about the time RH released their first RHEL.
You can't do an eye test on statistics, you need hard math.

I could easily say that example tracks with a normal shift starting in a busy period and petering off as demand drops moving away from peak hour.

If every Uber driver got the same number of trips every hour, at all hours of the day, something would be seriously wrong.
In theory, law enforcement.
You're right. We can't come to final conclusions yet.

However we can make some predictions. And it's not hard to predict how this will fail.

The root issue is that you've based your app on a number if assumptions, but your assumptions themselves are flawed.

For example you've assumed that the majority of people (as in more than 50%) agree on -anything-. You are assuming that the majority knows best. You're assuming that somehow politicians aren't already working this exact system.

In the real world everything is highly nuanced, and are a result of balances and compromises.

What you are proposing already exists. They're called elections, referendums and so on. Get enough people angry enough about something so they'll vote for you to stop it.

For example Brexit. An objectively stupid proposal, which convinced a majority through lies and false promises. Majority rule in action.

To be sure there are ways to make a difference. Political systems exist at each level. Get involved with your local council. Stand for office. Spend time understanding both sides of a position.

But another social network? It's too early to make a final conclusion, but I can make some pretty solid predictions.
> Congress never authorized the war.

The US aid to Ukraine that is the relation of the US government to the war is, in fact, authorized by Congress. See, e.g., the Ukraine Democracy Defense Lend-Lease Act of 2022 (PL 117-118).
Amazing.

Exploring the world of impossibilities is probably going to be a new kind of science.

So far, most of science has delved into what we think seems possible and tried to find our way towards it, but what about what seems impossible? How much exploration have we done in that direction? Well, AI seems to be the most equipped vehicle to explore this new world.

Theories are about to be proven wrong or right, no in-between. This is going to be interesting.

Not sure about the 10% point. You could imagine that we got “lucky” and a handful of simple proteins manage to produce the brain (or at least enough of the brain’s connections that the rest can be filled in during infancy via sensory input). Or put another way, maybe evolution optimized for brains that are incredibly adept while only taking a small number of codons (relative to the number of neurons) to describe. The fact that we've managed to l describe the universe through a small set of laws shows that the laws of the universe require much less space to encode than the universe itself, so it's theoretically possible.
I love how some Arri shills down-modded that. Or are they DJI shills?

If you already know any other language, then just Google the solution to that exercise and read it until you grok it. If you don't already know the basics, I found mimo to be great for a quick but not really deep dive in python. Great first step. Exercism is fantastic to learn the differences between languages. The mentoring is free, but it's one of the few online learning resources I would pay for.
Yes, everything except incandescent bulbs and space stations are pas sous vide. That’s where I find the humour: sous vide is simply an imprecise term for referring to a particular cooking method, but as it has escaped professional kitchens and made its way to home cooks, it has acquired a kind of respect as an arcane art that it arguably doesn’t deserve (and definitely doesn’t get in professional kitchens). I like pas sous vide because it’s an even more imprecise term. (It’s not a very funny joke, honestly.)
Jellyfin has clients. The mobile app and web clients work fine for me.
Literally the opposite of a hundred years of research.

Consider this - I'm 65 and do Uber part time because I'm bored. Now I'm 20 on a student visa with a work limit, and not many ways to support myself.

Who should get the next Uber trip? Should Uber flip a coin? Must we be paid the same? If the student is willing to work for less than what the senior would get out of bed for, why would a free market not allow this?

How do these dynamics affect the prices that customers pay?
Was confused, too. The non-local models should be denoted.
I think that's why a lot of encounters, and with someone getting killed, they figure they are going to die anyways, so they run, or fight back. It makes me wonder if we're heading towards a future, where more and more average every day citizens refuse to engage with police on any level.

Ah the reverse engineering of crashed ET craft.

If that is your angle, I very much agree it's possible some deep black project exists that (once) looked into this. In the UFO lore, there are many stories about these advances (tr3b etc).

But all of it is orthogonal to LLMs though. Picking one exceptional area that the military is great at (aerospace) does not suddenly make the military exceptional in other areas like AI.
Imagine if these were fully open source LLMs. None of them are

Then you could fix them

True. I've read a lot about reinforcement learning and the exploration vs exploitation tradeoff is both technically interesting and philosophically interesting. I've also seen algorithms I've implemented fall to all sorts of human-ish flaws, such as learned helplessness, etc.

Could the text size shrink using already trained LLMs? There is probably alot of irrelevant or wrong information in this data, and the LLMs could be used to remove this information.
To be fair, the parameter is called extra index url, not private index url.

Which app do you use to automatically index and organise the files?
It's not that postgres can't handle large tables, it's more that many of the ways it uses system tables aren't particularly optimized for them being large, so you're operating outside the territory the table/query design was probably built for.

Like most things postgres it'll probably still work better than it has any right to for a while, but it'd be extremely unsurprising if it caused you unexpected problems at some point. (And if it does, they'll likely excitingly novel and you'll probably have to dig pretty deep to understand what's going on.)
Performance is huuuge issue with RLS, as it works like an optimization barrier. Because of security RLS rules are applied initially and then all/most indexes you have just not working at all. ITs not like single WHERE clause with injected RLS checks

How do Embeddings work for you? I'm yet to play with them, but I imagine:
- with large corpus of text, they can be expensive to compute

- they may be limited in some cases - when you want to extract a deeper meaning from text - that is - gpt3/4 would figure out that an answer to a query is in a given document, but embeddings are way more shallow and will miss it

I know they are far better than previous search approaches, but do they have the limitations above?
That's not a good enough statement to really summarize Fourier transforms, I think? It really just summarizes the idea of an orthogonal basis.

Can someone validate I have this correct: I can use chatGPT through the browser (chat.openai.com) for free, but to use any of these clients, I need a paid subscription (after the initial $18 thing runs out).

Hmm... duh. Of course I just asked chatGPT this and got this reply, for anyone else wondering:

"Yes, you are correct that you can use ChatGPT through the browser for free by accessing the OpenAI GPT-3 Playground at chat.openai.com. However, if you want to use the API to integrate ChatGPT into your own software or application, you will need to sign up for a paid subscription after the initial $18 promotional credit runs out."
There is nothing reasonable about an existing system that was designed from the very start to shield monopolistic corporations from scrutiny. More so when it's illegal.

>It’s not quite true that every attacker has been thwarted.

When passengers have been able to intervene, they have defended their airplane 100% of the time.

When passengers have been prevented by regulatory means from defending themselves, they have failed to defend against a "trusted" figure turned attacker 100% of the time.

Sometimes the correct approach really is to do nothing.
Probabilistic linters does seem like a fruitful realm for them, yeah. A lot of code shares strong similarities with others in small scales, thanks to stack overflow and various other "help me solve X" -> "try Y" answer pairs.

I do wonder how to reliably tell it to ignore noisy, incorrect warnings though. They're potentially sensitive to any new input / weight / random-seed changes, so it seems like literally every LLM upgrade will run the risk of ignoring existing suppressions (or you say "ignore this whole line" and miss useful warnings) due to small perturbations...
You are not to blame for not understanding this, it's just that the analogy for the electric dipole moment coming from a non-spherical 'shape' of the electron is extremely bad. Moreover it's missing the most important reason why we search for EDMs, because the existence of one in an elementary particle would indicate the violation of the time-reversal symmetry (T), which assuming CPT conservation [1] leads to CP violation (Charge conjugation and parity symmetries). CP violation [2] is needed to explain the matter-antimatter asymmetry of the Universe.

A more proper way, in my opinion, to reason about an electric dipole moment is to think in terms of Feynman diagrams. An EDM (or any dipole moment for that matter) is an interaction of the electron with an electromagnetic field, so interaction between an electron and a photon. The most simple such interaction you can imagine is an electron flying in, at one point it absorbs a photon and flies out - that would be the magnetic dipole moment. You can go more complex though - electron flying in, at one point it emits a photon, then the electron interacts with the EM field (absorbing a photon) and then it reabsorbs the photon it has emitted previously. (Note that these analogies are again not perfect as for elementary particles time and space are not the same as in the macro world). Now, it can get even more complicated: If you have an electron it's not really a 100% pure electron. There is always some chance that it transforms for a short time into a quark or neutrino or whatever you can imagine.

When you analyze all such scenarios (electron going into something else, interacting with the EM field and then going back to an electron) some violate CP symmetry, and those contribute to the electric dipole moment. We use that name (dipole moment) as the final result is as if the electron was a ball with some separation between the negative and positive charges and placed into an electric field it experiences some torque. The analogy misses the most important part though, as if it was such a polarized 'ball' it would not violate CP symmetry.

Within the Standard Model the only source of CP violating interactions come from the weak interaction (CKM matrix). These have a very small contribution as the weak interaction is, as the name suggests, very weak. That's why the Standard Model predicts very tiny electric dipole moments. When we are searching for EDMs we are in fact searching for such rare transformations through some new undiscovered particle that violate CP symmetry. If we detect some non-zero EDM that would mean that there is some interaction that is not included in the standard model that violates CP, not that the electron is not a round sphere or a sphere with a bump.

I've found in my experience in in life that those whom comment are others use of swear words are often lacking individuals whom attempt to use their felt'superior language' to demean others. Particularly to demean others of a different cultural background than them.

> There are a lot of reasons that you don't want to coopt your database's role management to manage your app's users as well.

> Roles are global in the entire Postgres system, not scoped to a particular database.

A workaround is the db_user_namespace option

https://www.postgresql.org/docs/current/runtime-config-conne...

> db_user_namespace (boolean)

> This parameter enables per-database user names. It is off by default. This parameter can only be set in the postgresql.conf file or on the server command line.

> If this is on, you should create users as username@dbname. When username is passed by a connecting client, @ and the database name are appended to the user name and that database-specific user name is looked up by the server. Note that when you create users with names containing @ within the SQL environment, you will need to quote the user name.

> With this parameter enabled, you can still create ordinary global users. Simply append @ when specifying the user name in the client, e.g., joe@. The @ will be stripped off before the user name is looked up by the server.

> db_user_namespace causes the client's and server's user name representation to differ. Authentication checks are always done with the server's user name so authentication methods must be configured for the server's user name, not the client's. Because md5 uses the user name as salt on both the client and server, md5 cannot be used with db_user_namespace.

> Note

> This feature is intended as a temporary measure until a complete solution is found. At that time, this option will be removed.

It's a bit concerning that the documentation states that the option is intended to be removed; Postgresql has a ton of misfeatures that, in name of maintaining backwards compatibility, aren't removed just because new, better features are introduced.

However, I suppose that if a better way to scope roles is created, migration tools will be made available

>> I explained to her that open source might be a better way to get experience, and we looked into mentorship, which is how this thread started...

so I presume you ended up agreeing with her that an internship is a better place for getting the mentorship she's looking for?

I say that not to be a dick, or to cause gratuitous offense, but that sometimes, even as adults, we are wrong, and should admit it.

While mentorship programs can exist, and there's nothing stopping them using a open source project as a target, in concept open source and mentoring are not really related.

Both overlap as an "altruistic social good", but the kinds of people who delight in teaching and mentoring and the kinds who delight in writing code (as a way of avoiding social interaction?) would not seem to be a natural overlap.

The vast majority of open-source programmers are doing it for fun (not money) so in their spare time. They probably want to spend that time programming not mentoring. The few doing it as a paid gig, well, they have work to do.

This might just be one of those things that seems like a good fit, but really isn't.
