Why is there so much buzz about RAG?

Isn’t it basically a traditional search (either keyword based, vector based -embeddings have been around for years-, or a combination of both) where you take the top N results (usually not even full docs, but chunks due to context length limitations) and pass them to an LLM to regurgitate a response (hopefully without hallucinations), instead of simply listing the results right away? I think some implementations also ask the LLM to rewrite the user query to “capture the user intent”.

What I’m missing here? What makes it so useful?
I'm going to skip unnecessary stuff and:

> What I'm saying is that the relationship is not a causal relationship, in which the density decrease causes the volume increase. It is just a relationship that is enforced by the overall relationship between the spacetime geometry and the stress-energy tensor.

I'm not even sure why focus on casuality of the event. I'm more interested in whether that stress-energy tensor is a tool which lets us reason about any interesting info, such as:

Can we imagine a noticeable area of space suddently becoming empty and devoid of matter - would it cause the inflation, as in elongation of paths between ourselves and some distant object with this area between us, to become faster? Slower? Just about the same?

When you talk about a "local conservation law", do you mean that there's math which makes the energy difference go away, and then inflation goes at the same rate regardless of whether energy-losing matter (such as light) is present in the expanding area or not? Because that just does not sound satisfactory.

Imagine driving over a $100 bill lying on the ground and once you've past it the bill is gone. You can reason that the bill wasn't significantly thick, and when you drove over it you created some tension and a measurable local depression, but once you went past the ground returned to the same level as it were. That is indeed true and scientifically sound. But where's that money now? That is a question that needs some answer.

Maybe it's now stuck to your wheel, maybe it's under a film of dust now, or somebody have pocketed it. But there has to be some answer.

There are two basic solutions to this problem.

1. Everyone works less (the government mandates a 35, 30, 20... hour workweek), raising the relative value of labor.

2. We collectively do more than the bare minimum needed for survival and comfort (the government raises taxes, spending them on activities like building sports stadiums or moonbases), raising the demand for labor.

When I was a kid my parents had one of the Kodak instant cameras. I remember when Polaroid sued them out of existence and as part of a class action lawsuit my parents got a settlement. It was some coupons for Kodak brand batteries and one specific model of film camera we could never find in stock before it expired. https://www.nytimes.com/1988/05/17/business/kodak-to-compens...

That's when I learned class action lawsuits only benefit the lawyers.
Labor is fluid, if everyone working for a rich company should be rich, then why would anyone work for a not rich company? It would completely lock up the labor market, where everyone vies to work at the richest company rather than the company that can use their labor the best.
Why do you say there is a finite amount of work needed? There might be, at any one time, a finite amount of work someone is willing to pay x > 0 dollars for, but as x goes to 0 I’d intuitively think the amount of work increases indefinitely.

Share buybacks were illegal stock manipulation for the majority of the USAs existence, until Reagan legalized them. They need to be made illegal again, they serve no purpose other than short term stock manipulation. If companies have excess cash, they should issue dividends (which was a huge part of the reason stocks were initially desirable). People would then buy stocks with good dividends (i.e. long term value, versus short term quick gain).

yeah good question, if you're doing any sort of analytical work, then you'll care about the statistical distribution of your data. If you're running queries or sharing data with third parties, then you want to maintain the same stats. If you're just building features then you might not care as much as if you were doign analytical work. But it could still be relevant if you're building metrics/dashboards/anything visual - you'll want to see that you can render your prod data correctly. So more so for analytical work but less so for normal, run of the mill dev work.

What’s the real strategy here by OpenAI? A temporary cushion and a reprieve from complaints by big publishers?

All these deals they’re making will force other brands/orgs to follow, I am just wondering - once they get a taste of that free money, are they going to continue to follow those “highest journalistic standards” and talk about OpenAI in the context of copyright for everyone else.

Me attempting to summarize the article:

There are 2 ways to get C++-style RAII into C. The first way is to wholesale import the C++ object system into C (which means name mangling, all the different flavors of constructors, destructors, etc). Conceptually this would work, but it's never going to happen, because implementing that would be literally more work than an entire conforming C99 compiler.

The second way is to just use some special function attributes to signify that a function runs when an object is created on the stack / popped off the stack. This won't work either because the C++ object system also solves lots of other problems that this simpler system just ignores (such as, what happens when you copy an object that has a constructor function).
This is cool! It might sound silly, but figuring out `None` and `...` indexing in numpy was one of the more delightful moments of learning as a programmer for me.

Tangent: I wish we had not settled on the word "tensor" for multidimensional arrays. Yes there is some isomorphism with the multilinear map definition, but the huge majority of code using >2D arrays has nothing to do with multilinear maps.

S3 was/is optimised for a specific bunch of use cases.

Because EC2's hypervisor was (when it was launched) lacking features (no hot swap, not shared block storage, no host movements, no online backup/clone, no live recovery, no Highly available host failover ) S3 had to step in to pick up some of the slack that proper block or file storage would have taken.

For better or for worse, people adopted the ephemeral style of computing, and used s3 as the state store.

S3 got away with it because it was the only practical object store in town.

The biggest drawback that is still has (and will likely always have) is that you can't write parts to a file. its either replace or nothing.

But that's by design.

So I suspect it'll stay like that.

This could also be seen as a weakness. The lack of focus means fragmentation. Fragmentation means confusion. Users tend to want/need to know what to use and where to go. Telling someone, "go get an email account," will leave them asking more questions or giving up. It's a homework assignment for research. Telling someone, "go get a gmail account," is an actionable thing they can do. We made it there with email, but they were news anchors trying to explain it to people and a lot of friends helping friends, or simply ISPs setting it up for their customers. It's been 30 years of mainstream awareness.

I kind of wish this was a tool to author bash, or better yet very compatible POSIX sh. (versus being using bash as a compile target that a human isn't meant to read)

It's a bit of a stretch, but comparing it to something like MJML for HTML emails. [0] It doesn't make great HTML, but it's not unreadable and standard quality for HTML emails. It just handles all of the weird things you have to consider for maximum email client compatibility. It's basically a bunch of HTML macros, with react being an implementation detail under the hood. It's not like it's bringing any new features to HTML emails, because if it did, the output WOULD be unreadable.

If this was just some type hints, and cleaner syntax around sh, that I think would be really useful. This in it's current state is just sort of a tech debt generating machine. If something is built in amber, it's because we can only use bash for some reason, but if we can use bash we could either... use bash, or we could call something else (Ruby, Python, etc), from a 2 line bash script.

Edit: Idea, it would be cool if you could define the environment available to the final script when using the compiler. That way, if there was something you wanted to distribute, the person building your project could say "this docker container I'm running this in won't have sed, but it will have bc and awk" or something.

I definitely had advantages in that I knew tools like Khan Academy existed, was not battling depression, and also had talked to people who I admired and saw they were not so different than me. I also had a mother who loved me and a step-father who came into my life a bit later who cared, but they were dealing with some pretty big challenges of their own, including mental health, bad relationships, debt, children who were in and out of jail, and everything that comes with that. I do not like to spend too much time focused on race, but I am a white male, which was also an advantage.

At the time I was leveraging Khan Academy I was around 24, had distanced myself from the people I had grown up with who were not on a positive track. I also don't know how, but somehow I got it in my head that finance was the universal language and that learning more about finance was the key to understanding more about the world. So I was very focused on that. I had no clue what economics was at the time, but once I learned about that, I was addicted. Finding topics like that deeply interesting is a HUGE advantage.

At that time, I was living on my own and had a stable job managing a department at Home Depot. I slept on an air mattress and didn't have any money to speak of, but I had enough time on my hands that I could spend time at a coffee shop after work and on my days off working my way through the knowledge map on KA, starting with long division (which was humiliating) and learning how to do everything by hand, and then progressing from topic to topic. My goal was to not have to take a remedial math class at the local junior college (2 year colleges in the US). I spent months mastering basic math and worked my way to more advanced topics (1 million energy points on KA, not sure if that's a lot but I'm still proud of it).

One last advantage I had was that I genuinely enjoyed learning and talking to people, and it showed. And I was young. So people were willing to take the risk. Many people were willing to give me a chance, encouragement, and their time as I was making my way through school. If I had a question or was interested in a career or topic, I would just ask someone if I could call them or shadow them, and most the time they would say yes. I had nothing to lose by asking, and was always amazed how often it worked.

I try to share this with others who were in my position so they know it is possible.

Thank you for asking.

Because in the novel "1984", the slogan "Big Brother is watching you." literally contradicts that statement of yours.

So? You're missing the point. It'd still be miles and miles ahead of where we are today.

AND it'd still cost less money than we've spent today AND it'd keep money in the right places AND it'd provide plenty of useful jobs for people that need it.

This wasn't some hypothetical either. We had working standards and working prototypes for all of this. Congress was actually gearing up to make this a reality back around 2010. But Republicans.

If you're not too squeamish about this sort of thing, you could likely find out how to disable this yourself in your vehicle with a web search.

> What should I do to understand better why my churn rate is high?

A lot of products include some questions as a part of the cancellation flow to get more feedback from customers about why they're leaving. General startup advice is always "talk to customers", so at a small scale, you could also do things like offer a $25 Amazon gift card for them to get on a call where you could chat with them about why the product doesn't meet their needs.

Good luck!
