Double your compression ratio for the low, low price of 100,000x slower decompression (zstd: 215GB, 2.2 ns/byte vs. nncp: 106GB, 230 µs/byte)!

The neural network architectures are technically impressive, but unless there's some standard compression dictionary that works for everything (so the training/compression costs amortize down to nil), and silicon architecture dramatically changes to compute-on-memory, I don't know if this would ever take off. Lossy compression would probably provide huge advantages, but then you need to be domain specific, and can't slap it on anything.

According to Merriam Webster the definition of an ideology is one of the following

> a manner or the content of thinking characteristic of an individual, group, or culture

> the integrated assertions, theories and aims that constitute a sociopolitical program

> a systematic body of concepts especially about human life or culture

I am not sure how it could not be an ideology. Being against racism is an ideological idea as well.

I Created a Pet Age to Human Years Converter
Hey everyone! I recently created a pet age calculator that helps you convert your cat or dog’s age into human years and provides insights into their life stage. It’s a simple tool that I hope can help pet owners understand their furry friends better!
While I'm not sure I agree with the arguments, I don't think the arguments for starting over from scratch are insane: https://drewdevault.com/2024/08/30/2024-08-30-Rust-in-Linux-...

The core argument is that attempts to convert the Linux kernel to Rust are burning out the people putting in that work. The choice might not be between Rust in Linux or a new kernel, but between burned out devs failing to put Rust in Linux or a new Linux-compatible kernel written from scratch in Rust.

Ask HN: How did your startup job change as the company scales?
Currently working for a company with 10-20 employees and starting to scale rapidly.

For those of you who were relatively early employees at a startup, how did your job change as the company went from Seed/Series A to Series C+? How did your day-to-day change? Do you have any tips?

I'm planning to stay for a while and am curious about what the next few years will look like. Thanks!
As someone who works on TypeSpec, my feeling is that they are mostly different things. TypeSpec is a general purpose DSL which supports "emitting" to protobuf and other things, but in and of itself doesn't prescribe any particular protocol or serialization format.

Most places radar detectors are legal. Several courts have even said that the purpose of radar is to slow people down and so radar detectors work just as well as traffic tickets (this was years ago - I'm not sure what the latest case law is) and so you can't make them illegal. The FCC also generally says receivers are legal (again I haven't checked in 25 years so I'm not sure what the latest is).

Radar detector detectors exist and are used in places where radar detectors are illegal. As others have pointed out they are limit used against modern radar detectors.

Both Google and Apple. If you go to the App Store all games are ad ridden to the point where you can't play more than a minute without interruption or constant nagging to buy. Where are the apps where you pay a sum agreed from the start and use the damn app without restrictions? Some games will even trick people into buying $20/week subscriptions. I can only trust Apple Arcade for my kid. What a wasteland, probably no more than 1000 decent apps in millions. And they have the nerve to pretend App Store is some curated collection of software we can trust. It's no better than "shareware" before 2000's.

> Why not Jax?

- JAX Windows support is lacking

- CuPy is much closer to CUDA than JAX, so you can get better performance

- CuPy is generally more mature than JAX (fewer bugs)

- CuPy is more flexible thanks to cp.RawKernel

- (For those familiar with NumPy) CuPy is closer to NumPy than jax.numpy

But CuPy does not support automatic gradient computation, so if you do deep learning, use JAX instead. Or PyTorch, if you do not trust Google to maintain a project for a prolonged period of time https://killedbygoogle.com/

At the moment I’m working on a system to quickly replicate academic deep learning repos (papers) at scale. At least Amazon has a catalogue of prebuilt containers with cuda/pytorch combos. I still occasionally have an issue where the container works on my 3090 test bench but not on the T4 cloud node…
That's a best case number, based on warm power management, an operating system that isn't disabling interrupts, and the interrupt handler being warm in L2/L3 cache.

Note that things like PCIe MSI can add a couple hundred nanoseconds themselves if this is how the interrupt is arriving. If you need to load the interrupt handler out of SDRAM, add a couple hundred nanoseconds more, potentially.

And if you are using power management and let the system get into "colder" states, add tens of microseconds.
This is something I keep trying to point out to people. That doesn't mean that Linus is any kind of role model in this way - but people point to open-source interactions as especially "toxic" while ignoring (or being ignorant of) the fact that things are often _far worse_ behind closed doors. The differences being that 1) they're behind closed doors and therefore rarely seen, and 2) calling out a rude interactions in open-source projects is unlikely to get you fired or on the wrong exec's shitlist.
Solar has been cheap for a while now. I think what is changed now is that financial markets have become comfortable with financing solar projects. In the beginning it is hard to grade the risk of a project where cloudy weather or unproven degradation estimates can substantially change how much power is being generated and sold. To get a lot of projects financed, you had to come with a 10-year purchase agreement. The are only so many datacenters and industrial customers willing to do that.
Interesting, even with the 40% import duties (China to India), local prices still are very high. Im not sure how to explain why no one is using this arbitrage.
Where's the power source in the Arctic? The sun doesn't shine too strongly there if at all, so solar wouldn't work. Power would have to wired in from thousands of miles away, which is achievable, but that's extra work. Wind could work, but it would require vast batteries to supply a steady load.

Like with mining Bitcoin, the best place is where the power is available and cheapest.

It's even worse, you still need node to run this thing, so you don't avoid the node dependency.

Blisteringly fucking moronic that you double down.

So it seems it boils down to the difference between "delivery" and "processing".

I think we can make this distinction formally. For a given communication channel C, we can define "delivery via C" as a message showing up successfully at the receiver end of C. This definition seems unambiguous.

Now, we can phrase our "theorem" more carefully:

For an arbitrary given communication channel C, exactly-once delivery via C is generally impossible.

The important part here is "For an arbitrary given communication channel C". By adding a layer of deduplication on top of C, we would be constructing a new logical communication channel C', via which exactly-once delivery is indeed possible. But that would be a different channel C', not the original channel C that we were given. In this context, we can refer to delivery via C' as "processing" relative to the original channel C.
With the demand from server farms and new EV devices, grid prices are not coming down any time soon or at all. The hikes in the Bay Area alone have been 20% per year lately. Solar has become enough of a commodity that PGE pays atrocious rates for daytime energy, but battery power is golden after 6pm. Solar with batteries or just batteries for personal use can pay back for itself fast. With the money you might be able to buy the next generation solid state batteries when they come out.
I think reprocessing is actually cheaper than creating a new rod because you don't have to do as much enrichment of the uranium material. What I meant is the rod produces less power than a fresh replacement so it's better for the operator to replace it with a new rod to keep the reactor at it's design output.

The main reason the US is against it is because of old Cold War concerns about countries using it to harvest plutonium which is created in small amounts in regular reactors so there's a small concern that reprocessing would allow secretive creation of plutonium for nuclear weapons while appearing to be a purely peaceful civilian nuclear fuel reprocessing system.

If the speed limit is more than about 10mph then legal speeds are potentially deadly if you are hit. Deadliness goes up with speed, but by around 35mph it is safe to assume anyone hit will die - so if you are arguing about speeds faster than that it doesn't really matter anymore.
Ah, well, that's interesting! Does anyone know how cupy manages tensor mutability?
Interesting. One problem I'm facing is using RAG to retrieve applicable rules instead of knowledge (chunks): only rules that may apply to the context should be injected into the context. I haven't done any experiment, but one approach that I think could work would be to train small classifiers to determine whether a specific rule could apply. The main LLM would be tasked with determining whether the rule indeed applies or not for the current context.

An example: let's suppose you're using an LLM to play a multi user dungeon. In the past your character has behaved badly with taxis so that the game has decided to create a rule that says that whenever you try to enter a taxi you're kicked out: "we know who you are, we refuse to have you as a client until you formally apologize to the taxi company director". Upon apologizing, the rule is removed. Note that the director of the taxi company could be another player and be the one who issued the rule in the first place, to be enforced by his NPC fleet of taxis.

I'm wondering how well this could scale (with respect of number of active rules) and to which extent traditional RAG could be applied. It seems deciding whether a rule applies or not is a problem that is more abstract and difficult than deciding whether a chunk of knowledge is relevant or not.

In particular the main problem I have identified that makes it more difficult is the following dependency loop that doesn't appear with knowledge retrieval: you need to retrieve a rule to identify whether it applies or not. Does anyone know how this problem could be solved ?
What’s insane is that battery grid storage has already overtaken pumped hydro storage, and practically all of that is in just the last few years.

We haven’t really even ramped up production of battery chemistries that are tailor made for grid storage yet. Batteries like sodium-ion, molten metal or various flow batteries have basically no limits to how much we can scale them, and a really low potential price floor.

> Because it is. Why would I even care about "queerness" (whatever it actually means) in an open-source project for a sound recorder or video player or game or what have you?

Part of what "queerness" means here is "Could our conference invite a technical speaker who happened to be gay safely? Or would the speaker be in legal danger?"

Many organizations are committed to non-discrimination of various sorts. People's race, religion, or orientation shouldn't prevent them from participating in a conference. And this is often a written organizational policy in the US and Europe.

And if such an organization decides to host a conference in a country where (like Tanzania) being gay might subject some of their members to life imprisonment, some of those people are going to ask, "Hey, don't we have a written, official policy against doing that?"

Now, the complicating factor here is that large parts of Africa criminalize being gay, and obviously the Python community would like to hold some conferences in Africa. But at the same time, they presumably don't want to risk any of their members being subject to life in prison.
Stop Bullying LLMs
I've been getting into LLMs and seeing how to empower them. By treating them as a human (they've been trained on our content after all!), it makes sense to give them the ability to write code and use it just like a developer.

This might be massively derivative and it's already a well-understood approach? Would love to hear more from people in the know. The script at the bottom is more a first step to breaking it out of its own mind, there are many things you could hand it to use to carry out a task?

as someone who divorced and didn't want to be the 'mac and cheese dad', I found an older edition of "Williams Sonoma Cooking at Home" a really good beginner book. It goes over basic ingredients, seasonality, cooking methods, cooking tools, proper measuring, and complementary sides before hopping into recipes. I found all of these very valuable as _tons_ of recipes assume basic knowledge of it.

A lot of the recipes are quite involved though so now I tend to go for simpler ones, or pick-and-choose.

I only happen to know because I bought a slightly used car in which the first owner had an Escort Max Ci professionally installed. Sensor in the bumper cover, display and controls mounted to the dash with hidden hard-wiring, quite nice.

There were a ton of false positives from non-police sources at first, especially Cadillacs if I recall correctly. Then I learned how to disable alerts on all the bands except those known to be used in the places I do most of my driving (2 states) based on websites that specialize in such information. I think I reduced it from like 30 slices of the K band down to about 6 or 7. Problem solved! Granted, it introduces the possibility of encountering police who use bands I've disabled, but I prefer that over a bad SNR. Now I see a cop for about 1/4 of the alerts which is pretty nice. Visible line of sight is often not until the alert has been going for sufficient time to acknowledge.
You don't get a bonus and promotion for just using TypeScript.
