Just go to Perplexity or something like that, its well trodden ground. And essentially, what you're doing is discretizing the relevant differential equations and getting that to run in a 2D or 3D cellular automaton.

I'll give you a simple example. For diffusion of heat between 2 points, the rate of change (first derivative) is proportional to the difference in temp between them. So you make an update rule for points on a grid that says "calc the average difference of a cell's temp with that of its neighbors, multiply by some constant, and that is the amount to update this cell at this time. Run that for every cell in parallel, many times." Then you tack on a visualization and you can watch the heat diffuse. A fun example would be the cooling of the proto-Earth. You can watch the crust form.

Heat diffusion is a good starter problem. So is gravitational interaction.

Re:Why U.S. dominance at sea is shrinking on Wednesday July 23, 2025 @12:16PM (#44660877)
The entire model of sea-borne power projection has changed. What does it mean when hypersonic missiles can be fitted with optical sensors to autonomously target ships? It means carriers now are about as useful as battleships in WW2. Nobody knows who can dominate which parts of the world ocean anymore.
I am in denial.

I find for auto turn detection, models work better if you put in the system prompt "if it seems the user hasnt completed their thought yet, output silence". This hack works around their compulsive need to output something.

What is SOTA for retrieval in RAG systems now?

Have there been significant improvements this year?The simple flow we landed on in 2024 was:1. Chunk and embed docs with embedding model 2. Embed query (maybe using an LLM to reformulate first) 3. Retrieve N1 docs using cosine similarity 4. Narrow to N2 using a reranking model 5. Inject these docs into context to generate answerHave there been significant advancements? Has anyone had seen...

I lived with a host family in Lima for 9 months on their roof. They treated me like a son. Extreme tourism.
I would try the Qwen models before LLaVa

Do you need the embeddings to be private? Or just the photos?

The point is to colonize Gaza, they won't irradiate it first.
When Netanyahu called the Palestinians Amalek when speaking to the military after October 7th, why do you think he did that? Amalek, the people the Jewish people were commanded to destroy in the Torah?

Why do you think Israel initially funded Hamas? Why would they want these conditions to occur? What must the true goals of the Israeli state be for them to see Hamas as useful?

Or let's go back to the founding of Israel...

Do you know about the Dalet Plan, put forth by Ben-Gurion in the 1948 war: "The plan's tactics involved laying siege to Palestinian Arab villages, bombing neighbourhoods of cities, forced expulsion of their inhabitants, and setting fields and houses on fire and detonating TNT in the rubble to prevent any return."

Or even its precedent, the 1937 Avnir plan, conceived a decade before the 1948 war and before World War 2 (!): "In the summer of 1937, the commander of their forces in the Tel Aviv area, Elimelech Slikowitz (nicknamed Avnir) received an order from Ben-Gurion, according to the official history of the Haganah. Ben-Gurion, anticipating an eventual British withdrawal from the country after the Peel Report, asked Avnir to prepare a plan for the military conquest of the whole of Palestine. This Avnir Plan provided a blueprint for future plans. The blueprint was refined in subsequent adjustments (A, B, C) before emerging in its final form over a decade later as Plan Dalet."

Conquest, genocide and ethnic cleansing has been the goal from the beginning and continues to be.

Let's close with some quotes by Ben-Gvir, the minister of national security, and Smotrich, who administers most of the West Bank:

"Nobody will let us cause two million civilians to die of hunger, even though it might be justified and moral, until our hostages are returned."

"My right, my wife’s, my children’s, to move around on the roads of Judea and Samaria is more important than the right of movement of the Arabs."

"I think the village of Huwara needs to be wiped out. I think the State of Israel should do it."

“Let’s make a decision to end Gaza once and for all"

"The state of Israel is first and foremost Jewish and only then democratic and a judge in a Jewish state must, first of all, consider the State’s Jewish values. Evicting Jews from any settlement is contrary to the decree of the Torah and to Jewish law. It harms the Jewish values of the state and therefore it is not hypocrisy to say that the expulsion of Jews from their homes harms the Jewish value of the state and the expulsion of an enemy from his home is something completely different."

Referring to the annexation of the West Bank: "[I am] In favor of sovereignty, but not in a way that adds hundreds of thousands of enemies. A program that encourages emigration is better..."

Israel has been harming civilians intentionally for a long time, it was built on it, and that is its ultimate goal.

Netanyahu, when addressing the troops, even said "Do not forget what Amalek has done to you", invoking the memory of the biblical commandment to genocide the Amalekites.
Does anyone think this is about anything other than stamping out criticism of Israel?
Is this really that bad for Google? Do Perplexity and OpenAI use paid SERP API under the hood? Google doesn't have to make money from ads on search, if its paid search.
Ghislaine Maxwell, for instance, was a mod on /r/worldnews and one of the most prolific posters.

I'm curious what your viewpoint is here. Is human extinction a bad thing? And if not, do you care if it's your own descendants thriving, versus the descendants of an immigrant?
Electric cars are mainstream now. Reusable rockets are real. Twitter won an election and spawned XAI. Elon is the richest man in the world. Yeah bro, he's a moron. Sure.

I've never understood what the real reason we invaded was. I just know it wasn't what we said, or oil.

This makes me think the first to make a really successful model will be the ones to pony up to get human feedback at scale from the smartest humans instead of what they do now.
I think his point is that things very rarely experience purely compressive forces. Just being compressed induces tension in other directions, like water being squished out between your clapping hands. So even though water has great compressive strength, in practice this isn't very useful.

Re:OpenAI releases image generation in the API on Friday April 25, 2025 @11:23AM (#43794544)
What you're saying just isn't true.

I can get an AI to generate an image of a bear wearing a sombrero. There are no images of this in its training data, but there are bears, and there are images of sombreros, and other things wearing sombreros. It can combine the distributions in a plausible way.

If I am trying to train a small model to fit into the optical sensor of a warhead to target bears wearing sombreros, this synthetic training set would be very useful.

Same thing with artillery in bushes. Or artillery in different lighting conditions. This stuff is useful to saturate the input space with synthetic examples.

I am trying Geocod.io right now and its been a very smooth experience so far. Generous free tier, no credit card required, good docs and a dedicated node library. And I can store results.

Yeah Ollantaytambo was Inca. They say it was constructed as a vacation estate for Pachacutec (?) after he conquered the Sacred Valley.
I don't see how anyone can look at the generation that survived the great depression, and look at boomers/millenials/gen Z and not see the truth of it
