It's going to get interesting once Slack (or a partner) starts offering access to models which have been trained on conversations, either from your workspace or globally across all workspaces. Or maybe a combination of both (say, an industry-specific model that gets refined using recent data from your workspace). This could be quite useful. On the other hand, it looks like a security nightmare, even if the makers of the model think they have successfully mitigated the risks (which they always do, and never achieve).

Slack clarified their privacy policy in January that they consider message contents unrestricted data (that they can share freely) after it has been de-identified. Essentially, they changed “We may disclose or use aggregated or de-identified Other Information for any purpose” to “We may disclose or use aggregated or de-identified Information for any purpose”. “Other Information” does not include message contents, but plain “Information” does. Of course, de-identification (to protect user privacy) is likely to retain confidential business information, such as customer names, the technologies they use, and so on. I don't think it's an actual change to the policy, because this kind of permission was heavily implied by the privacy policy before.

It's unclear to me if the permission we have to grant individually, before we can use a Slack workspace, overrides contractual obligations negotiated by the workspace owner regarding message confidentiality. I assume that Slack has a “you pay for confidentiality” model, but I'm not sure how far it actually goes, given that change to the privacy policy.

I'm a bit sceptical about this. This guy was taking goverment and EU money promising self driving taxies fleet, he was supposed to deliver 2 years ago. China already has them cruising their street, Tesla also had some great success with self driving, yet from Rimac there is nothing, no progress, nothing to show.
The underlying principle in Crystal is that data structures usually require explicit declaration while types of values passed around on the stack usually don't need to be declared. I find it makes it easy to reason about the result while still being very stream lined.
I don’t think RocketLab had plans to ever commercially launch rockets out of NZ.

Its latitude is really not optimal for anything other than polar orbits and it’s too far from any potential customers which would increase the cost considerably.
The Buran had about the same payload capacity as the Space Shuttle (slightly more even). It's first (and only) orbital test flight was in '88, 2.5 years before the Salyut deorbit. Had the Soviet Union been just a smidge more solvent and politically stable we might have the whole Salyut 7 sitting in a museum somewhere. All it would have taken was a slightly accelerated Buran program, a Soviet Union that survived maybe 3 years longer, and a decision that bringing back a decommissioned station is a great test mission that boosts national pride. A near miss in history.

I will throw this on the table (and quickly hide my hand behind my back):

If the price model (IMHO correctly) is connected to the actual costs of the search, why not make a "searches account"?

You pay 5$ per month as a "baseline" and each first of the month 200 searches are credited on your account.

Then, if you use less than 200 searches, at the end of the month you have a credit that goes over to next month.

If your credit goes to 0 within a month, you can buy "packets" of searches, 5$ for 200, 10$ for 500, or something like that, and recharge your account.

Element is banned, not Matrix. A more realistic alternative would be a client such as FluffyChat.
I would encourage you to wade into commentary on the man strangled to death on the NYC subway if you think it’s outlandish that some people see the lives of the homeless as essentially disposable. Or you could just scroll down to the person in this very discussion thread who more or less argues for deaths from exposure. Or we could look at preferences revealed by policy demands, which often take more of an "out of sight, out of mind" approach.

I looked at the concepts in FAISS and it seems fairly straightforward. In non-jargon you have dimensionality reduction and neighborhoods.

DR is taking a long embedding and doing something to make it shorter. An easy to follow method for this is minhash.

Neighborhoods is representing a cluster of embeddings with a single representative to speed up comparisons. For example, find me the two closest representatives then doing a deeper comparison on all the residents.

Now the feature I haven't seem that will probably cause me to build instead of buy. Most seem designed for a single organization and a single use. For example, Spotify song recommender.

I would like to store embedding from multiple models and be able to search per model. I would also like fine grain user access control, so users could search their embeddings and grant access to others.
At this point (and after seeing the same thing working with Deno), I would love if the Swift team created some opt-in swift-2.0 mode that would get rid of that bits of syntax sugar that make Swift slow to compile.

Signal Groups V2 is a privacy downgrade
> The Element app is just one of many apps that give access to the Matrix network. A simple parallel is that banning Element because it gives access to the Matrix network is the equivalent to blocking Google Chrome because it gives people access to the web, or Gmail because it gives people access to email.

Outlook would have been a better example than Gmail for email.
They banned it for gathering data they are not supposed to just like India. But Element & other secure communication services are being banned for a tangential reason

and a "vector database" is a collection of vectors, sure.

The question comes from is it the CompSci | HN | AI domain nomenclature to assume a vector database is made up of vectors that are all of the same dimension over a continuum (eg. N real numbers for fixed N) or are vector databases made up of mixed vectors (no fixed dimension) and discrete values, etc.

I ask as the linked article doesn't specify but does appear to imply.
I produced those links by finding the post on each server so I was also surprised that they redirect when accessed directly.

Nobody is upset because nobody is aware (this is hyperbole; obviously some people are aware and upset). But from my time in the states, it is very clear how effective US propaganda is. Working Americans don't realise they are paying a huge amount in taxes, and believe they can't have nice things like healthcare and retirement.
I was assuming they were referring to the data collection, storage, and processing and model training.

> f we all drove 160mph road tolls would skyrocket.
You can bring up the autobahn if you like

Okay, I will. 99% of autobahn traffic I have seen drives 200kmph or less. 160 mph is 257.5 kmph - a quarter more than 99% of autobahn traffic.

200 kmph is fast if it's busy, and most cars can't go significantly beyond that. Aiming for 260 is dangerous for folks driving 200, let alone those driving 100 (yes, that is not an uncommon speed - also not in the unrestricted areas).

In other words: bonkers by autobahn standards.

Simple: Renewables. In 2030, 80% of the generated power should come from renewables [1].

Starting from 2025, each year, 7,8GW of wind and 22GW solar power will be added into the mix.

For reference, the nuclear plants we just shut down produced 4GW in total.

Germany is exporting excess energy each years to France and other neighbours. 2002 was the last year we had to import energy. [2]

> classrooms are full of other children

of the same age.

> Classrooms empty into lunchrooms and schoolyards, which are not segregated by year.

In my experience, in elementary school our class had assigned tables for lunch and a specific time when we had the playground and blacktop. YMMV. But at any rate a half hour in the cafeteria and a half hour in the yard aren't the best places a child could learn to interact with other children; the characteristics of these activities are constrained by the form of the institution.
Not really. For starters not all the vectors in the database are of the same dimension (at least in ones I've used). You can for example in pgvector have multiple tables with a column of vector type and those tables can have different cardinality.

In any case your description is strangely reductionist. The important thing about a vector db is that is typically designed to store embeddings used in various ML applications. So say you are doing NLP you can tokenize some input and then store the token and positional embeddings in a vector db and then use it for similarity search, training etc.
Just like in the original, I think it’s only going to work in theory.
No mention of andOTP...?
Does anyone have some real, production experience with milvus? I'm interested this database performs in larger scale. Let's say, you have millions of vectors and traffic reaching thousands requests/s.

So empty article on the main page. All you need to read is following:

Not surprisingly, such an ambitious project has aroused skepticism. Its proponents have not yet made clear how it might be tested in the lab. And some scientists wonder whether assembly theory can even deliver on its more modest promises to distinguish life from nonlife, and to think about complexity in a new way.
Lobbyists would be hurt by term limits. The big winners would be the permanent bureaucracy, who are already more-or-less in charge. The real solution is to allow old school purges when parties trade control of government.
You should really know that there's more to ML than neural networks. Those are the simpler approaches I was referring to (like linear models, ensemble models etc). They are

1. Machine learning.

2. Not neural networks.

3. Not in Norvig's book.

4. Still useful and relevant.
Shareholders gain pennies with moats, pennies that someone else does not earn. Without moats they benefit much more, but it's not more than someone else. And that's the contentious issue. How would I benefit more than my neighbor?

Amen. After suffering through many years of people telling me to use document databases when I was much better served with—at most—Postgres with a jsonb field, I feel vindicated enough to feel justified in doing my due diligence before going off the beaten track.

Not that document databases don’t have their place, but…MongoDB is webscale and all that.

The burden with Ruby is that there is no clear way of shipping an application to the end users without requiring the end user to install the runtime.

Crystal might be the proper solution as the syntax is almost identical (if not is already) and I can finally ship self contained binaries!
Don't know, you're in WG14, not me :D

Maybe 'const' can't be fixed without breaking existing source code?

I don't really have a problem with adding a new keyword for 'actually const', maybe calling it 'constexpr' means C++ people have wrong expectations though, dunno.

For me, having constexpr being explicit about only accepting actual constant expressions, and creating an error otherwise (instead of silently falling back to a 'runtime expression') is fine, but the existing keyword 'const' has an entirely different meaning, there's just an unfortunate naming collision with other languages where const means 'compile time constant'.
Everyone has some sort of moral philosophy that influences their political choices. Do you vote for giving food stamps to poor people? That’s based on a moral judgment. “Secular government” doesn’t mean that policies based on secular philosophies somehow are given preference over those based on religious moral philosophies. If the regulation itself is otherwise within the government’s power, you don’t look behind to people’s motivations and decide that one policy is acceptable because it’s based on socialism and another policy is unacceptable because it’s based on Christian social gospel.

For political purposes, Christianity is just another “ism” that motivates people’s political choices. If the government has the power to restrict access to porn under the first amendment, then it doesn’t matter whether people support such restrictions because they are Christian and think that porn creates social harm or because they read Andrea Dworkin and think that porn creates social harm: https://www.nytimes.com/2021/09/24/opinion/sex-positivity-fe....
The fediverse has a problem with discovery, I agree on that piece. Coming from outside the network and trying to access a particular post or user profile is not smooth, mostly because it takes you to the wrong server (I don't use chaos.social, links to there are useless to me).

I've explained in other comments how a URL scheme would help with this.

There are many non-technical users on fediverse and it's working just fine for them, I see their posts all the time saying that they're having a good time despite your scare quotes. The problem in this case is HN users who aren't on the network anywhere, and there's not much I can do about that. I think if you were on it and had a home server this would not be that confusing, you'd just search for the post. Ideally you could skip the search step as well which is why I keep coming back to a URL scheme solution.

Over the past couple of days I tried 11 different vector databases, in order to evaluate and decide which one we'd choose for our use case.

Governments make these things called laws. If you don't follow them they have people with boots and clubs that can take your money, lock you away and/or just rough you up a little when they take your phone to look what's on there.

They don't have to make it impossible to get the app, they might not even want to make it impossible! Because now instead of surveillance or not, dissidents (well, everyone) have the choice between surveillance and being a criminal that they can Protect and Serve(tm) at their discretion.

This is what the politicians mean when they say the laws of mathematics are below the laws of the country, and they're absolutely right. Don't bring tech to a legal fight, you will lose.
They were so busy spreading a political message that they forgot to help the users. Sure, it sucks that Element was banned but they would highlight the fact that affected users can use other Matrix clients.
That's too native. Output is indeed cooled but only enough to be only fraction hotter then input. Then dumping is safe again.

This is also why most of those power plants have to shut down. It's not the physical lack of water, but instead input is already so hot that output would already be over the upper limit.

Nobody build enough cooling towers to cool with them "needlessly".

Which is also why global warming is disastrous to energy sector. Those older power plants just don't have enough cooling capacity for newer higher temperatures.
Can you search both by an equality comparison and a vector search in weaviate? I’d like to do something along the lines of `SELECT * FROM table t WHERE cosine_dist(:my_embedding, t.doc_embedding) < :x AND some_column = “XYZ”`
