I do not believe 70M households have fiber available. I have searched many, many houses in many, many metros, and the ones with fiber are few and far between.

The FCC map is not reliable at all. You only see that fiber is not available when you search the address on the ISP website and it returns with the option for DSL. Even in the region I live now, the FCC map says fiber available in most of the city, but in reality, it’s only the newer housing developments. 90% are older homes in developments from a couple decades ago, and they only have coaxial.

The common factor in fiber availability is a housing development built after 2005 or even 2010, or built so long ago that the utilities are overhead and maybe they could string up fiber for a sufficiently low price.

Any home in any development built 1970 to 2010 with underground utilities that did not already have fiber will most likely not have fiber.

Also, any apartment building from before ~2010 will not have Ethernet wired to the apartment, only coaxial wires, and the apartment building owner is not going to wire it up for fiber, even if fiber is run to the building itself.
It seems to me that women and non-white people are just as vulnerable to hype cycles and cult behaviour as white men are.

I do agree that lack of "well-roundedness", for lack of a better word, in some tech circles is part of the cause of this sort of thing. But again, non-white men are just as vulnerable to that as white men.

I can't comment on what changing the weights of the KL divergence does in this context, but generally

> Is that what KL divergence does?

KL divergence is basically a distance "metric" in the space of probability distributions. If you have two probability distributions A and B, you can ask how similar they are. "Metric" is in scare quotes because you can't actually get a distance function in the usual sense. For example, dist(A,B) != dist(B,A).

If you think about the distribution as giving information about things, then the distance function should say two things are close if they provide similar information and are distant if one provides more information about something than the other.

The comment claims (and I assume they know what they're talking about) that after training we want the KL divergence to be close to a standard Gaussian. So that would mean that our statistical distribution gives roughly the same information as a standard Gaussian. It sounds like this distribution has a whole lot of information in one heavily localized area though (or maybe too little information in that area, I'm not sure which way it goes).

75,000 in savings over 6 years is $12,500 a year, which means this person's utility bills were over $1000 a month!? I know that my house is wildly inefficient and $300-$400 a month is the worst it gets with extreme weather.

Talking with friends and family my bills are higher than normal, most are around $200 and less in the milder months. A quick search shows $469 being average us Utility bills and that includes water, trash and internet.

> Post modernism has given us .. a set of tools to deconstruct any human concept you can name, until it can be shown as meaningless. Which, I would posit, is the “end of enlightenment”.

I enjoyed reading this pithy summary of post-modernism. As for the parent post:

> it's stunted our emotional and social development, bringing us to the brink of total war and social disintegration.

This was the doing of "modernism", the age of reason, the enlightenment, and the industrial age. Post-modernism is the questioning and subversion of that grand narrative of objectivity, rationality, science, social progress.

From the wasteland of everything deconstructed as meaningless.. Hopefully something new can be born, maybe even a "spiritual language in the vocabulary of science and empiricism".

One man’s experience in DC (where the SRECs are crazy valuable):

Installed 10Mwh system in 2021 for ~$40k.

After federal tax credits, SREC earnings, reductions in electric bills, and payments from electric co for over production, we have $7k left to recoup in only 3 years. And that ignores savings from the gas we’re not spending on charging the PHEV.

I know it’s a luxury to have, but there’s also some pride value (clearly!). Fortunate circumstance if you’re in the right place and have the cash. I wish the investment was more broadly accessible.
I've actually found the animations helpful even thought was initially skeptical: Because it visualises the vim motions it makes it much clearer what is happening. Especially if you make a mistake you'll see it much more clearly what it actually did. Also when making longer cursor jumps it is easier to see where it went.

I'm sure they will help a lot also when learning Vim for the first time.

But the be fair, the default animations are bit much but they can be toned down.

>I honestly have no idea at all what the OP has found or what it means, but it doesnt seem that surprising that modifying the latent results in global changes in the output.

It only happens in one specific spot: https://i.imgur.com/8DSJYPP.png and https://i.imgur.com/WJsWG78.png. The fact that a single spot in the latent has such a huge impact on the whole image is not a good thing, because the diffusion model will treat that area as equal to the rest of the latent, without giving it more importance. The loss of the diffusion model is applied at the latent level, not the pixel level, so that you don't have to propagate the gradient of the VAE decoder during the training of the diffusion model, so it's unaware of the importance of that spot in the resulting image.

Eh, after some lost packages, dealing with USPS for claims, wanting to touch the product before purchasing, and easier returns, I find myself returning to brick and mortar lately.
Most flat roofs aren't really flat. They're built with a slight slope, I think it's a 2% slope, or 1/4" for every 12", towards a drain.
Solar and batteries pays off pretty quickly and can bring you to a net zero position on electrical needs fairly easily (excess sold in summer, importing in the winter). On an annual basis I now power half of another home in addition to my own. If I take the total expected output over 25 years my electricity cost is 1/4 of what it would be from the grid per KW/h. I went 6 months last year importing almost nothing from the grid.

In the UK at least batteries and an inverter are actually quicker to pay off using an economy 7 electricity tariff since power overnight is less than half the price of during the day and is typically from Wind power and imported Nuclear from France. That can pay off in less than 4 years and will last 10-15 with li-po.

If you don't have a roof to put solar on then there are some cooperative schemes where you can own part of a solar/wind installation and still save on your bill. A national one is https://rippleenergy.com/ but there may be more local schemes that you could help fund and get the payback from, residents are banding together to build solar farms all over the country.

The big energy companies have messed up this transition to green energy terribly and its considerably cheaper to make your own power than buy from them, which lets be honest it shouldn't be.
One of difficulties with property testing is that humans are notably bad at specifying good enough properties. A canonical example is sorting: if your property is that every consecutive element should be ordered, an implementation that duplicates some element in place of others won't be caught. We can't always come up with a complete property, but intuitive cases can improve otherwise incomplete properties.
I keep seeing YouTube shorts of guys going up to highway guardrails, checking them out and discovering that they were improperly installed like no nuts or that the bolts aren’t torqued down enough.

In 2021, I ran a two-team, two-codebase detangling project with 20 engineers. Both codebases were writing to the same database, but one was the leader for some fields and the other was the leader for the rest. It was causing serious production issues in a highly regulated field, so we fixed it as fast and accurately as possible with almost no downtime. The very first thing was building in automated error detection processes so we could have product staff catching and fixing errors live.

We split the work into six releases over six months. Separating the two systems required a totally different architecture with a significant amount of code changes in the one system.

We didn't exactly use this method step by step (I hadn't heard of it). We thought logically through all the steps, and then reversed them. There were spike branches that we used to gather all the steps, and then we did delete them. But we only used maybe 4 or 5 spike branches total. Unit tests didn't drive anything - these changes were more system-integration level, so there weren't existing unit tests we could use.

In the end, it worked, we made a major overhaul to the one system and updated the second to now be the leader on all. We built an API on the second system, so it could be called by the first when new records needed to be created.

So I'd say, conceptually this method is what we used, but really none of our to-do list was generated from unit tests. Perhaps we could have built out a ton of tests and separated it into a release every week or every day, but we felt comfortable with the monthly releases. That helped because the QA process was pretty long (a lot of features in a regulated industry). Each release they were testing for at least a week. That being said, we built out a lot of unit tests to complement the changes, and I don't think QA found any issues in any of the six releases.

As the author described it, Mikado method is recursive. You find a to-do list on the first branch, then possibly more things on the second branch, and more things on the third. We only did one "loop", maybe two, where the author might do many.

I got this by thinking about the Kent Beck quote "first make the change easy, then make the easy change".
I agree with a lot of what the author is saying here. If it matters, whatever it is, don’t use AI to directly generate it.

There is one great use of ChatGPT that I don’t think violates any of the author’s principles. When you’re trying to search for something on google, but you don’t know the words to use, and nobody you know is familiar with the topic, ChatGPT is great at giving you the words you need to continue your own search. This continues to be the most impressive types of “conversations” I’ve had with it.
I am worried about the changes in laws this will bring.

As on date, the state cannot force you to testify against your own interests. It is the states responsibility to ensure it finds the evidence to present to courts.

With situations like this, the chipping away of rights will begin.

How do the cops know which is real and which is fake? Make the convict tell.

The problem is a tech problem, which has to be solved by techies. Otherwise, we will land up into a quagmire of privacy and state protections eroding, or the AI technology itself will be heavily regulated / banned.

I have to mention that in California, a non-profit Foundation based at Stanford already made a close legal deal with PG&E, to identify sites and install very high quality equipment at deep discounts, in exchange for long-term binding agreements. The consumer is not paid enough to eliminate the bill, just "close".

The quality of the siting, equipment, strictness and result of the legal agreement, all indicate to me a very carefully built system, not necessarily to the full benefit of the consumer. It may be that a) ad-hoc and disperse efforts like yourself may still be attractive, and b) the market forces are still changing, so better deals for consumers might be possible.

I take the time to write because this is important IMHO.
Within the last two-ish years, the NIST settled on some post quantum crypto algorithms and there's been some implementation of them more and more since. Quantum computing is still far off, but I think the mindset is "why not start now?"

I don't know for certain, but I'd assume things like elliptic curve were implemented a good bit before it garnered mainstream usage. I'd love for someone who was around that when it was happening to correct me if I'm wrong though.
Small towns don’t typically have malls. Small towns are more on the order of “oh we just got a walmart”. I think you’re conflating small towns with mid to large towns or small cities.

When other cultures try to impose their morals on the west, we say it is oppression (eg. compulsary headscarves). When we try to impose our morals on others, that's somehow totally different, and they need to follow our rules even if they're in a totally different country.
I’ve done a lot of experiments with latent diffusion and also discovered a few flaws in the SD VAE’s training and architecture, which have hardly no attention brought to them. This is concerning as the VAE is a crucial competent when it comes to image quality and is responsible for many of the artefacts associated with AI generated imagery, and no amount of training the diffusion model will fix them.

A few I’ve seen are:

- The goal should be to have latent outputs as closely resemble gaussian distributed terms between -1 and 1 with a variance of 1, but the outputs are unbounded (you could easily clamp or apply tanh to force them to be between -1 and 1), and the KL loss weight is too low, hence why the latents are weighed by a magic number to more closely fit the -1 to 1 range before being invested by the diffusion model.

- To decrease the computational load of the diffusion model, you should reduce the spatial dimensions of the input - having a low number of channels is irrelevant. The SD VAE turns each 8x8x3 block into a 1x1x4 block when it could be turning it into a 1x1x8 (or even higher) block and preserve much more detail at basically 0 computational cost, since the first operation the diffusion model does is apply a convolution to greatly increase the number of channels.

- The discriminator is based on a tiny PatchGAN, which is an ancient model by modern standards. You can have much better results by applying some of the GAN research of the last few years, or of course using a diffusion decoder which is then distilled either with consistency or adversarial distillation.

- KL divergence in general is not even the most optimal way to achieve the goals of a latent diffusion model’s VAE, which is to decrease the spatial dimensions of the input images and have a latent space that’s robust to noise and local perturbations. I’ve had better results with a vanilla AE, clamping the outputs, having a variance loss term and applying various perturbations to the latents before they are ingested by the decoder.
Gotta disagree. It's neat, but I don't like to see it in the real world.

For a start, I don't know how to type these on a keyboard.

Secondly, most people wouldn't know what these symbols are called. Granted, those looking at the code probably have a greater chance of knowing. But it isn't friendly code in my opinion. I think clarity is key, and "rho" or "sigma" are pretty clear.

Also, add in that there's a constant "n" and a constant "η". Just begging for confusion.

Yes, though it'd be perhaps more accurate to say it expanded upon the theme, as Wikipedia says.
Show HN: Dera – A platform to manage chunks and embeddings for building RAG apps
Hi everyone,

my cofounder and I built Dera - a platform to help manage chunks and embeddings.

We built this because of the pain points we experienced while building RAG applications for side projects. The biggest pain point we encountered was that we were constantly trying out different chunking strategies, but there’s no easy way to check how the strategies are performing in terms of retrieval when given the same query.

We tried searching for a tool for this but couldn’t find any (most LLM dev tools focus on prompts management).

We hope this tool will be useful for people building RAG apps.

Thank you!

On games, sgt-puzzles and bsdgames fit well, among nethack/slashem, DCSS and OFC Frotz too plus a few libre games (Spiritwrak and such).
Slashem+BSDGames+3 adventures for Frotz would weight less than 20MB I think. Compressed, about 7.

BTW, I'd ditch XMMS for Audacious; a Pentium 3/4 today would be more than enough to run it.

BTW Visidata it's huge, use sc-im+Gnuplot.
