pg_embedding is based on a different approximate nearest neighbors algorithm - HNSW, which is generally considered - and studied - to be faster as well as more accurate than pgvectors IVF (ignoring a lot of nuance).

However pg_embedding serves the index out of disk, whereas most vector databases opt to serve the index out of memory, or delegate to mmap'ed files. HNSW is a graph-based algorithm, thus access patterns are random and this does not lend itself to disk based access. I'd expect pg_embedding to be slower than memory-resident indices due to this fact. Also in general with a postgres index, my concern would be scalability and resource isolation. It's convenient to colocate these things but ANN indices have very different CPU/Memory/Disk usage patterns than what you may need for just your relational data.

For example

Chroma -> Serves HNSW out of memory, persists to disk with a WAL.

Weviate -> Serves HNSW out of memory, writes HNSW graph search to WAL and uses that for durability.

Milvus -> Serves HNSW out of memory, supports partial mmap, also supports another algorithm called DiskANN which is optimized for SSD. It uses cloud storage with a shared-everything architecture for durability (a lot of nuance here.)

QDrant -> Has a WAL, supports memory and mmap'ed indices.
Right. Instead of manufacturing a 50, 80, and 100 kWh battery pack, and having to go through the whole process of getting certifications and everything for each size, they just make 100 kWh packs all day long, and then software limit them to 50. Which means, in the case of an emergency, the company can bestow extra range on lower-end vehicles, which they did for Hurricane Irma.

There's no reason to limit the components people can tinker with to electronics! Everyone is free to (attempt to) replace their brake fluid - or repair the brakes - which can cause disaster at high speeds if not done correctly. I'm yet to hear anyone asking for access to vehicular hydraulics to be locked down in order to protect people from themselves.
In this case I find the argument relevant. Why?

In my country (and I assume it's similar in others), Microsoft has and traditionally always had schools, hospitals and governments, pretty much the whole public sector in tight grip.

There is a lengthy history behind that which includes numerous reasons.

Parent comment was making the comparison because GP pointed out the absurdity of forcing kids into Google ecosystem and exposing them to data harvesting.

When the original story was about MS and they behave in similar or the same ways, I believe that it's very relevant.

Two wrongs don't make one right though: students at a public school, their data as well as their mindshare, should not mandatorily be sold to the highest/lowest bidder.
This is extremely stupid. We have had electric trains for 200 years and hydrogen was not involved.

Tmobile and others have some ot-in feature that prevent most of the scam calls from getting to your phone. I went from a couple a day to a couple a week after turning it on.
That would not catch every public IP address that is actually unused, because it can be attached to an interface and yet not be needed or actually used by any client. But I don't agree with GP that this is an important reason for the price increase. They are increasing prices simply because costs have increased.

Yes it is which is why Lightsail exists. The whole mantra of the cloud is only pay for what you need and scale down to zero.
This is comparing apples and oranges. You've pointed to some technologies from vector database vendors. Neon isn't a vector database vendor. They're a Postgres vendor. The objective of pg_embedding, pg_vector, and others is to offer teams who deploy Postgres the opportunity to use their existing infrastructure for vector search. The added and important benefit here is hybrid search: using existing DB data to filter semantic search results.

What the work done by Neon, the pgvector team, Supabase and others points to is that "speed" isn't the only factor in vector database selection. Developer experience and existing infrastructure investment are too.
This finally puts real pressure on software and services to work on IPv6 only. I wouldn't be surprised if within 1-2 release cycles lots of distributions suddenly update just fine with just IPv6, package mangers can download packages over IPv6, lots of APIs gain solid and well-tested IPv6 support, etc.
Overhead wires take quite a while to plan and build and for non-frequent service (1tph) and/or short trains installation costs and maintenance are quite high compared to buying e.g. BEMUs. Many of these services are shuttle runs with electrification at one or both ends and route lengths of less than 100km, so e.g. a Mireo Plus B with ~120 seats only a 580kWh battery (or less than 6 Tesla Model X batteries ) is used (https://www.vde.com/resource/blob/1979350/a41e9c3559af76fee9... page 24)

HEMUs for these types of services I don't understand. It's laudable that transit providers want to get away from fossil fuels (and putting up overhead wire is a long and arduous process, fraught with delays), but getting hydrogen today almost certainly isn't "green". Maybe "Technologieoffenheit" virtue signalling.

But looking at the plans of various german transit agencies for future service on non-electrified lines, it's pretty obvious that hydrogen has already lost for rail-based transit, with almost every tender that doesn't prescribe a technology going to BEMUs and studies showing that BEMUs and partial electrification or full electrification almost always makes more sense than HEMUs
You could watch someone work and know what words they were putting down by where they were reaching, even if you were too far away to make out the letters themselves.

If you pick the letters by word, you can guess what word as there are only so many words. It'd be like watching a touch typist on a unlabeled keyboard for another example.
Worse, ChromeOS is actually GNU/Linux, so it's hard to distinguish technically (unlike Android/Linux). I personally lean towards "user-controlled Linux" or such.

Nope, that is just a form of NAT one is forced to use for IPv4, with a stateful session table. It is that session tracking which adds the "outbound initiated" only behaviour.

There is a form of NAT for IPv6 (NPTv6) which can be used to gain pseudo provider independence. It has static mapping rules, with no session table. It allows for "inbound initiated" sessions.

So it is NAT which is globally reachable, without the endpoint addresses being globally routable.

That in no way resembles his work experience. He did tell me a few interesting things, though. He was really surprised how many software devs he met who were driving the big rigs. It seems to be a thing.

Another was how many skills overlap the two fields. Driving the big rig is an exercise in resource management and planning, so you can do things like ensure that by the time you need more fuel, you're in a place where the fuel costs are lower.

If they can turn on developer mode, they can run sudo dev_install, which will bring up a gentoo environment on which ChromeOS is based on, and then they have access to portage, and git --help. Outside of that, GalliumOS runs pretty well on most of them.

This is a pretty extreme article, but I think the argument is not that it doesn't exist but rather that it is blown out of proportion. The metric that is used to calculate obesity (specifically at the time they reference) was BMI which is a fairly flawed metric and significantly the obesity line was lowered. Idk how it is calculated now.

Thanks for explaining. This is confusing to me as a github user, i.e. if I saw a license in the project’s description, I wouldn’t expect another license in a subdirectory.

Github now has UI for repos with multiple licenses: https://github.blog/changelog/2022-05-26-easily-discover-and... , that would have been clearer for me.

> Because they did ship like that, years ago

Yeah, years ago.

Years ago there was no encryption whatsoever.

"Host based" authentication was common. And not the type that used certificates (or, in fact, cryptography of any kind), but the kind where you would enter IP addresses, host names, or even just patterns of those into a file called ".rhosts", and those then were the hosts that were allowed to run commands as root completely without further authentication.

When you shared a folder in Windows using SMB, you usually shared it to anyone, including the Internet. Windows did not even have a good concept of separate user accounts. This is not an exaggeration, a very significant portion of unsuspecting users had their hard disk made available to everyone because they intended to share it with their own little local network. No password, no nothing.

The Internet was littered with public FTP servers, of which a lot, and a lot of very public ones, had a directory called "/incoming" where you could upload and make available things for everyone else.

IRC had a thing called "CTCP", client-to-client-protocol, with which two users' IRC clients communicated directly, client IP to client IP. That's right, you were chatting (or not chatting) to some "rando", and they not only had your IP address, they had the ability to send commands to your IRC client.

WiFi, for a surprisingly long time, had encryption optional. And when it was turned on, it was easy to crack.

The Internet was a very trusting place, and became gradually less so. With or without NAT, routers would have added strict, stateful firewalls, for the same reasons that everything else I've written above stopped.

An Unexpected Twist in the Saga of the Crypto Couple
Doing Q&A with Thousands of Documents
For example, if you think the Crown still wields real power in Australia, could they today go to some remote Aboriginal community they supposedly "own," and tell those people to clear out so they can build a big resort, and pocket the profits?

If they tried that there would be massive outrage, and immediate action to leave the Commonwealth.

Yet relatively small construction firms pull this sort of thing successfully everyday, all around the world. It would seem to me, those ordinary construction firms each have more real power than the Crown.

Neom in Saudi Arabia is also an example where this was actually done in modern times, showing that The House of Saud wields massive power.

Your assertion seems to be that the Crown is so powerful that they don't need to actually do anything? That sounds like insisting I'm the strongest man in the world, and am so strong I don't need to lift anything. Power is fleeting, and rapidly evaporates when it isn't wielded.
Q&A with documents is the most common use cases for LLMs today. But scaling from one or two documents to thousands can be challenging. This blog explores the challenges in scaling such solutions and what Neum AI is going to help.
Encapsulation and ease of reusability / configuration?

Just as an example - a widget to manage a list of number ranges. Build it up like a form element - it provides a value prop with the type ‘[number,number][]’

You need to display the current collection of min/max pairs, and add / remove / edit the collection - it’s essentially a mini CRUD component.

There is no default html element that provides this functionality - you need an ordered list of pairs of number inputs, a confirm changes button, a ‘add new’ and ‘remove this entry’ button - you need a whole collection of stuff to provide the functionality.

But once you’ve got it all worked out, wrap it in a web component and you can use it in 8 different places across your admin tool - ‘<ranges-picker />’ and boom, you’re ready to go.

Using web components to define a library of common interface elements works just fine.
Amazon Earning Results Q2 2023
> Otherwise, you're undercharging for the original deliverable, and overcharging for the actual "downloadable content".

This is called price discrimination and it’s a great thing. You’re talking about under/over charging but that’s absurd: there is no such thing. People pay what something is worth to them.

What you’re advocating for creates actual economic inefficiencies: the people who don’t want the DLC must either pay a higher price, or not make the purchase at all, and the people who would happily pay for the additional DLC now get a net cheaper price, despite a willingness to pay more.
The main benefit of hydrogen that it is cheaper to store energy for long periods. When electricity comes mostly from renewables, which is expected to lead to very low, zero or even negative electricity during periods with lots of sun and/or wind, hydrogen could be produced for the cost of capital of electrolyzers + storage, which might tip the scales in favor of hydrogen.
While I empathize that companies have to choose a release pathway that limits cost, I will not be a customer of a product whose release pathway is just a Chrome plugin. From where I'm sitting, that's less cost limiting and more customer limiting.

DiskANN construction is much much slower than HNSW, and the support around updates has been discussed in literature but has not been open sourced yet (They call this FreshDiskANN in the paper - DiskANN is from microsoft research btw).

HNSW-IF is an excellent extension to HNSW (that the vespa team has made easy to implement) that takes advantage of the speed/recall of HNSW in combination with the disk scalability of inverted indices - it is a hybrid approach.
What instability does Kenya have? There are sporadic minimal localized protests about the cost of living that happen now and then, but nothing on the scale of the animosity that exists between different religious groups in India (that flares up now and then, according to what I see in the news, which I recognize could be leading to me doing what I'm accusing you of). And $300 per month is too low, even in Kenya. That's what I earned in my first underpaid practically-an-unpaid-internship straight-out-of-university job 15 years ago.

Implementing a challenge system could be a potential solution. In this system, each outgoing call would require the caller to pay a dime as a deposit. If the recipient marks the call as legitimate after the conversation, either through the app or website, the caller would receive the dime back.

To ensure customer convenience, inbound business numbers could have the option to opt out of the challenge deposit requirement, allowing customers to call in without any deposit.

While requiring all outgoing calls to be charged might be more effective, it might not be a popular direction, especially in the United States. Thus, the challenge system with a deposit and the optional opt-out for inbound business numbers appears to be a more balanced and acceptable approach, considering both the need for legitimacy verification and user satisfaction.

Almost everything else sounds like a fiction made up by Ingram, who wrote the "definitive" book 70+ years after the events took place, loosely based on the facts he was able to gather.

The article is still interesting, especially the part about the societal issues at the time that influenced Ingram, but the mystery of the Bell Witch seems to be a teenager who wanted to marry a boy, and didn't much like her dad.
