The article says we can build grid forming inverters, which can solve the reliability issues of highly renewable grids, and used Hawaii as an example of how to do this. These inverters are expensive. As a utility I can finance grid upgrades through corporate bonds or, or as you said, with investor money. Bonds need to be paid back in a defined time period, investors expect a ~10%/yr ROE, or else they do flee. As a utility, investments I make are financed through ratepayer funds. The problem has shifted from engineering, to financial, to political. I need to ask my states utility commission for a raise in rates. This hits on affordability issues, poverty etc. Who pays for it? Who benefits? This is determined by state elections.

RAGKit with Kyle Davis – Weaviate Podcast #93
Hey everyone! I am SUPER excited to publish our newest Weaviate podcast with Kyle Davis, the creator of RAGKit!

At a high-level, the podcast covers our understanding of RAG systems through 4 key areas: (1) Ingest / ETL, (2) Search, (3) Generate / Agents, and (4) Evaluation.

Discussing these lead to all sorts of topics from Knowledge Graph RAG, to Function Calling and Tool Selection, Re-ranking, Quantization, and many more!

This discussion forced me to re-think many of my previously held beliefs about the current RAG stack, particularly the definition of “Agents”. I came in believing that the best way of viewing “Agents” is an abstraction on top of multiple pipelines, such as an “Email Agent”, but Kyle presented the idea of looking at “Agents” as scoping the tools each LLM call is connected to, such as `read_email` or `calculator`. Would love to know what people think about this one, as I think getting a consensus definition of “Agents” can clarify a lot of the current confusion for people building with LLMs / Generative AI.

I hope you find the podcast useful, this was such a fun one! Thank you so much for joining Kyle!

MSRP was also lower for it, even accounting for inflation, compared to the cybertruck.

Downvoters need to explain why they are downvoting my post pointing out that a cheaper Lexus doesn't have this issue.
>If your $1000 becomes $1600, and prices went up 30%, then you can buy more stuff then before.

Again, your money does not increase like this. Only assets do. Stocks in particular go up in price due to inflation and naturally-occurring profit. You're the one asserting that assets ought to be brought into it, and I've been telling you that assets do not avoid the consequences of inflation.

>I don't care what you define profit as.

>The comment I replied to didn't use the word profit, and I didn't use the word profit in my reply. You brought the word profit into the conversation. I didn't use the word profit the way you wanted, I guess. So I will stop using the word profit. Problem solved.

Look, I don't think the original comment mentioned stocks either. You're the one who brought that into the equation. They did not gain because of inflation. They at best held value despite inflation. The reason they went up in terms of dollars is largely due to the depreciation of the dollar, and secondarily because of profits (using the dollar-based definition or purchasing-power definition, it doesn't matter). You're pointing to stocks as if they are a life hack for beating inflation, or even something to be taken for granted, and I'm here to tell you that they're not.

>You mentioned fixed incomes increased based on official CPI numbers earlier, right? That's enough to prove the point I was making. The cost of living adjustment just has to be more than 0 for my argument to be correct.

When they say the number is 6-8% and inflation is raging at 20%, your "point" is not helpful. Even if you're right, it's a pointless observation. Inflation is still bad mmmkay?

>Lagging doesn't affect my point as long as the lag is less than four years. Gaslit too-small numbers don't affect my point as long as the gaslit numbers are still above 0.

What does 4 years have to do with it? With even one year of high prices, you will lose a hell of a lot of money.

>Let's have an example number. For this example let's pretend prices went up 30%. If I say "relative to your income and savings, you're paying 25% more", I'm not saying "it's not so bad". That situation is really bad. I'm just saying it's not 30%.
>
>And it's important to realize that those numbers are different if we want to do accurate calculations about inflation. I'm not pointing out the difference for the sake of pedantry.

You are getting awfully pedantic. We talk about inflation in terms of price hikes because that's something that affects everyone. Accounting for all the inflation avoidance schemes and possible wage increases that people get to cope with inflation would require a different statistic. Those coping mechanisms are a red herring when it comes to the actual performance of our currency, which is what people actually care about.
Hector Martin has a different analysis:

This article talks about TB4 vs USB4 but that's a
red herring. This has nothing to do with USB4 and
Intel USB4 compliant controllers have the same problem.

The real reason Apple Silicon is faster is simple:
Intel Thunderbolt controllers are *external* and
bottlenecked on a PCIe 3.0 x4 link to the host,
while Apple Silicon *embeds* the controllers right
into the SoC, so there is no physical PCIe link
anywhere. They connect directly to the much faster
SoC fabric, so have no such bottleneck.

I can't say whether he's right or not, but it sounds plausible.
I assume you’re joking :)

For what it’s worth, at least some Tesla models turn off acceleration when the brake is pressed more than a little bit.
I'd say partial application solves a different problem than default parameters. Partial application is a convenient way for users of an API to define default behavior (but can easily be emulated by lambdas/closures), whereas default arguments allow API designers to define default behavior.
My strategy against them was hide and seek. The tactical peekaboo.

I would look fast, see where the Gatling gun sparks appeared, hide fast, wait a second for the bullets to hit something, then move again, shoot at where the sparks were an instant before, and hide again.

This was my tactic for the invisible ones, the others were easy, as they can't aim while being shot. For the visible ones, the missiles were made just for them.
This is where I feel both good as a consumer but I understand why companies are so disincentivized to make good products now.

I'm still on my M1 MBP from when they launched in Fall 2021 and I feel like I could use this thing for another several years easy. There's no chance of the average programmer hitting a wall (except maybe people deeply involved in running local LLMs) that requires an upgrade and they pretty much fixed every single issue with their laptops in one shot.

I do see these artificial limitations in their product lineup. For example, you can't get a 1TB SSD in their 16" MBP unless you get the M3 Max as opposed to the M3 Pro which is a $600 upgrade. Vs in their 14" you can get a 1TB at their middle configuration for only a $200 upgrade from their base configuration.

What else can they really do to get people on an upgrade treadmill ala iPhones (another area which has slowed down significantly)? If they let you configure the base models with 32GB of ram and a 1TB SSD there'd be literally nothing else to upgrade.

They already introduced a new color for the conspicuous consumption types (I haven't even seen one of those super dark gray ones in the wild.)
Exactly. People are getting too caught up on AI or not. If an article is good, it's good, regardless of AI.
That doesn't compute at all.
> They enter a prompt and the AI generates an image of, let's say a chair that looks cool at first glance and they think that AI is ready to take away the design jobs

Well, I'd say this is wrong, but not for that reason. The advances you list are all really engineering and materials science advances. Once an engineer shows you how to design a skyscraper using a framed tubes, you can draw 100 of them. AI might be able to do the drawing, but it probably won't be doing the structural engineering / materials science in the same ways.
What's your point actually?
I love info, and wish more developer docs where available on Info. Saves me from opening up a PDF - navigating an info-based reference manual is more ergonomic in comparison
I'm a regular emacs user but I completely understand this sentiment. It looks gnarly and puts many people off.

The relatively smaller share plus the ban means the US isn't dependent on Russia for Uranium, which is what was implied.
>AI-generated content has really dropped the floor on how cheap it is to produce niche blogspam

For all the potential good utility AI has, my current outlook is that it's primarily going to be used as a noise-generator at scale. As long as there's money (or influence) to be had from clicks and advertisement, the near-zero cost of AI-generated content means people will take advantage of that arbitrage opportunity.

Absolutely true. I bought a second hand MS Sidewinder for this game, and I still have it =)

Good question. I googled and found out that the highest clouds are the noctilucent clouds. They don’t contain dust, but tiny ice crystals, which are less than 0.1 microns in size. They can be found as high as 80km. Maybe you calibrate the airship speed so that hitting such a cloud in the “danger zone” does not damage the balloon. When you are above 80 km, you step on the gas.
Highly recommend Physically Based Rendering. As a book, Pbrt is to the study of path tracers, as Gravity is to the field of general relativity. Wholly encompassing and rigorous.
Intentionally triggering headlines like this contribute to the erosion of trust in media - the article even recognises its own provocation in the second paragraph. The reality is Gen Z are entering a job market of where the compensation is inadequate for the essentials of living - rent, fuel, food, medical insurance.

It also does not factor in debt from college, which many Gen Z-ers carry into the working world and never find release from. 'College for everyone' has burdened two generations with the prospect of indentured service to whichever employer eventually ends up hiring them.

The fact that they are dropping out, giving up, returning back to family home - are all matters which we should be collectively concerned about. Divisive headlines like this does not help

NAT is more like the add-on that most network operators don’t decide to employ for IPv6-only networks anymore, but NAT by itself is not part of IPv4. You can NAT IPv6 networks perfectly fine - but for IPv4 it is often a necessary evil when private network ranges overlap or you need to represent a single IP to the outside world.
We think that RAG is fundamentally limited:

https://www.aryn.ai/post/rag-is-a-band-aid-we-need-llm-power...

We do see a world where LLMs are used to answer questions (Luna), but it’s a more complex compound AI system that references a corpus (knowledge source), and uses LLMs to process that data.

The discussion around context sizes is a red herring. They can’t grow as fast the demand for data.
I can’t tell if DHH means to prepare his audience for a conservative coming out announcement, or if these posts are just “no such thing as bad publicity” for niche products.

I never got around to renaming “master” to “main.” No one on the team complained or found it “problematic.” No woke police came around to force us. DHH must have higher sensitivity to social media than I do.
Does it override the accelerator?

Do you trust Space Karen enough to make that assumption?

Tesla vehicles have a lot of software onboard, and they build it like a regular SV tech company. That is frightening to me.
For anyone trying to test the brake + accelerator safety system in a Toyota, there are no mechanical components. It's entirely in software and only engages when specific conditions are met. (Sufficient speeds sufficient pressure on the brake, accelerator pressed before brake, etc.)

Please do not test safety systems, especially in a Toyota. They only work in specific conditions and usually too late for you to react if it doesn't trigger.
As an iPhone user, the seamless integration, user-friendly interface, and quality hardware/software have kept me loyal. Additionally, investment in iOS-specific apps and accessories makes switching to Android challenging. While Android offers customization and device variety, Apple's ecosystem and overall experience are compelling reasons to stay.
Yeah, exactly this. I'm still on a nearly 4-year-old 16GB M1 MacBook Air. I'm coding SwiftUI, cutting 4K video, and using local 7B models.

If I could spec an M4 MacBook Air up to 32GB of RAM, and it was better with local models, I would strongly consider it, but man… this M1 is still more than enough.
Surely something with a higher energy output to waste ratio like nuclear energy waste would be an even better compromise then?
There’s also the laws of large numbers here. When you make hundreds and thousands of guesses, even with really high accuracy, you’re going to get some wrong. For a 4K movie at 24 frames a second, you’re talking millions of guesses per minute, perhaps billions or more over the length of an entire film. It’s inevitable you’re going to get weird glitches, artifacts, or just parts that look “off”.

It’s better to use a light touch for techniques like this rather just blindly applying it to the entire film.
Who comes up with this shit? “The global south?” The folks affected by this are mainly Chinese, which is at the same latitude as the US. All of India likewise is in the northern hemisphere. What’s the term “south” even meant to euphemistically reference? If you mean poor countries just say that.
The precision of a laser cutter would open up a lot of possibilities. Particularly making things that slot together with tabs - like fabbing my own welding squares and fixtures where a cnc plasma cutter would leave too rough an edge to have them slot together accurately.
Here's a question you can ask yourself: "where does my context fall within the distribution of human knowledge?" RAG is increasingly necessary as your context moves towards the tail.

From the politicians pushing it. There's only one size fits all solutions. There's never an acceptance that people can have different circumstances.
> Extending the address space didn't need a complete rework and rethink how local network routing works, removal of standard NAT and messing around with address assignment (DHCPv6, SLAAC, and all of those messes).

I think the issue here is that IPv6, despite being the successor to IPv4, is actually quite old in itself; it was developed starting in the early 90's and so it's just a different idea of what the internet was going to be. NAT is more like a "hack" that developed around that time as well and has turned into the normal way networks are managed.
Yeah, something like the (even more) heavily modified DeLorean Doc Brown returned with from 2015. Key technologies still missing would be (a) the energy source (a "Mr. Fusion" which can generate energy from random garbage you throw into it) and (b) some kind of levitation not based on rotors, rockets or jet engines (anti-gravity?), apparently also used in the hoverboards.

> Reaching net-zero-carbon emissions by 2050, as many international organizations now insist is necessary to stave off dire climate consequences, will require a rapid and massive shift in electricity-generating infrastructures.

Vaclav Smil's excellent analysis on this is worth reading: https://privatebank.jpmorgan.com/content/dam/jpm-wm-aem/glob...

The tl;dr is that net zero by 2050 would require all major economies to spend 15-20% of GDP for the next 26 years uninterrupted. For reference, the entire US federal budget was around 23.7% of GDP in 2023.

It simply is not going to happen, and pretending it will greatly undermines the pragmatic conversations we should be having about adaptation.

I think there's a strong optimistic case that the private sector can get us there by 2100 or so - lots of fundamental advancements can happen in that timeframe - but hamfisted government policy in the EU and America that blunts economic growth will mean there's less money to spend on solving these problems in the future.

I may not be part of the collective here, but I find it within the realm of acceptable that a $30,000 car would have issues that should absolutely not be present on a $100,000 car.

Transmission has a bunch of problems with DC as well. Transformers are fundamentally AC devices; if you want to use them in a DC circuit, you need an inverter anyway to convert the DC to AC and back again. There are ways to step up DC voltage, but none are as cheap or reliable at utility scale as a transformer is. If you don't step up the voltage, you'll lose basically all your power to transmission losses, since delivering high power at low voltage requires high current, and power loss increases with the square of the current.

High-voltage DC is also extremely dangerous, as it's prone to arcing and electrocution.
