The current stage of finance interview is a little bit like coding interview 20 years ago, pre-leetcode time, where you write sudo code on a paper to answer some coding challenges. The coding interview nowadays are quite advanced, I believe Leetcode plays huge role.

The best way of learning financial modeling is by doing it on the excel. Even though many finance technical interviews still focus on behavior type of questions, discussing your model-building approach and assumptions. By practising different scenarios on Excel, timeboxing it, it will help you refine your responses during the interview.
> But say, 10% meat. So that's 40 days, that's 9 deer per family per year at least

Maybe this was added after your comment, but that's ~1.25 lb / d for a family of four. A quarter pound hamburger every night, and snack sticks with lunch. Much more reasonable.
Decompilations and recompilations have been really interesting lately. They seem largely driven by fans interested in replaying old content in ways the original sources haven't provided. E.g. rather than "run normal N64 Mario and Zelda on your switch" you can run them at 4k120 FPS widescreen with all sorts of QoL improvements, modifications, or new gameplay modes. Even extremely classic titles like Super Mario Bros. 3 or The Legend of Zelda a Link to the Past get widescreen hacks.

Of course there are other benefits too that some use for playing the originals as they were. Some just want to more easily read through the games code to figure out how it works, hunt for new glitches, figure out why that odd thing in a speedrun happens. Others want to mine for cut/missing content.

I personally hope https://zeldaret.github.io/tww/ gets completed this decade. Nintendo has at least made an actual remake of this game, adding a certain level of the improvements and enhancements, but there are still more which would be nice (more than 30 FPS anyone?) and I can only imagine what kinds of customizations would be made feasible.
You can legally make your own firearms. It's a right that predates modern technology, which simply makes it more accessible. The term "ghost gun" is designed to mislead and promote unnecessary gun control by framing a legal practice as something to fear.

And the idea that people are "Skirting around the law" isn't true. Making your own guns is legal.

This reminds me of a fun experience I had in grad school. I was working on writing some fast code to compute something I can no longer explain, to help my advisor in his computational approach to the Birch and Swinnerton-Dyer conjecture. I gave a talk at a number theory seminar a few towns over, and was asked if I was doing this in hopes of reinforcing the evidence behind the conjecture. I said with a grin, "well, no, I'd much rather find a counterexample." The crowd went wild; I've never made a group of experts so angry as that day.

Well, I never was much of a number theorist. I never did come to understand the basic definitions behind the BSD conjecture. Number theory is so old, so deep, that writing a PhD on the topic is the step one takes to become a novice. Where I say that I didn't understand the definitions, I certainly knew them and understood the notation. But there's a depth of intuition that I never arrived at. So the uproar of experts, angry that I had the audacity to hope for a counterexample, left me more curious than shaken: what do they see, that they cannot yet put words to?

I am delighted by these advances in formalism. It makes the field feel infinitely more approachable, as I was a programmer long before I called myself a mathematician, and programming is still my "native tongue." To the engineers despairing at this story, take it from me: this article shows that our anxiety at the perceived lack of formalism is justified, but we must remember that anxiety is a feeling -- and the proper response to that feeling is curiosity, not avoidance.

From what I've seen of "ai" so far I doubt this product adds value to a team. But it doesn't matter! Using them means the CEO gets to say he is embracing ai in his products, and the engineering manager gets to say he's improving his teams velocity by using ai, and resumes and stock go up in value and around we go!

Show HN: New Cartesia Text-to-Speech Model
Hi HN - team behind Cartesia here!

We just announced our $27M seed today (https://techcrunch.com/2024/12/12/cartesia-claims-its-ai-is-...) + some major product updates we are excited to share with the developer community.

Our latest releases:
sonic-preview - a new model building on a new architecture that includes fundamental improvements over common TTS architectures which can struggle to follow complex, repetitive transcripts – you can find a fun example here (https://youtu.be/JTAmu8_qY4E)! Try this new model in the playground under sonic-preview and it will be available via the API over the coming weeks.
Multilingual Improvements - We launched a new multilingual model with enhanced number, date, and time recognition, as well as improved volume stability. Try it out in the playground or via our API!

Why Developers Are Building With Cartesia Today:

- We have the lowest latency at 90ms time to first audio, enabling truly real-time conversation

- We have the highest quality, ultra-realistic voices as determined by respected third-party evals like Labelbox: https://labelbox.com/guides/evaluating-leading-text-to-speec....

- We can clone voices instantly, using only 5s of speech, and don’t cap the number of voices you can create

- We can fine-tune professional voice clones using ~30 min of speech

- We support 15 different languages, offer emotion and speed control, localization to different accents, and voice changer capabilities.

- We offer all this and more at a more affordable price than competitors due to our innovative SSM architecture perfected for voice. SSMs offer clear advantages over transformers as they scale linearly with sequence length and enable cheap, high-throughput inference. Our founding team authored the widely cited Mamba SSM paper and our team has since built our models to be highly efficient, with better long-term memory, lower latency, and the ability to run locally on any device.

- If you’re an early-stage startup building with voice, check out our startup grant (https://cartesia.ai/startup) or YC deal (https://deals.ycombinator.com/deals/2877) and qualify for 4 months on our scale tier (8M char/mo).

You can try all of these features on our playground yourself: play.cartesia.ai, or if you have questions for the team or are interested in an enterprise plan with us, email support@cartesia.ai.

This thread seems to be about good writing for math.

Okay, for some decades, I've read, written, taught, applied, and published, in total, quite a lot of math. Got a Ph.D. in applied math.

Yes, there are problems in writing math, that is, some math is poorly written.

But, some math is quite nicely written. (1) Of course, at least define every symbol before using it. (2) It helps to motivate some math before presenting it. (3) Sometimes intuitive statments can help.

For more, carefully reading some well-written math can help learning how to
write math well:

I'm so glad companies and in this case a university are reaching out to youth to get them excited in these fields. Just wish it was more widespread. Can you imagine being credited on a scientific paper while you're in middle school? I know they probably didn't do a lot of the hard work, but when you're that age, working with adults and being encouraged like that, I'm sure it's an amazing feeling.
How to think about your documentation?
At Tensorfuse we have been rewriting and restructuring our docs as they have become a huge dump of how to guides rather than being something that is navigable and understandable. After a lot of peer discussion and reading, we are now trying the diataxis approach and it seems to be working with our beta users for now. Sharing it here as some people might be looking to make their documentation more navigable.

Last I checked deer numbers are has high as anytime in the past, maybe even more. There are less predators (they can eat humans so we don't want them around) and deer have figured out how to live around humans just fine. Deer numbers were way down in say 1960 (as you say they were hunted to near extinction) but with stronger hunting and environmental laws they have come back.

Of course hunter/gather lifestyles never supported large concentrations of humans like ag did.

This is a good way to put it. Because we humans tend to eliminate the large predators that we need to control some populations, we have a bunch of potential protein that would otherwise go to waste, why not mix it in?

There's room for tofu and meat in a diet, and if you're hurting financially things like this program, married with other cheap protein sources, is not only a great way to go but what a morale booster.

When I was a kid and we were broke a friend of ours gave my mom some rabbit. Alone it's not fatty enough to keep you alive but she mixed it up well with other stuff and we felt like we were having a feast.

Regarding the environmental downside of cattle, I couldn't agree more. We know several plains farmers who don't keep cattle but, after harvest let deer come onto their land to eat the leftover stuff in the ground and poop it back out as fertilizer. Once that's cleared out they shoot the deer and sell the meat. Yeah it isn't as profitable as a CAFO, but it's a hell of a lot less work, actually helps the land, and it tastes pretty good too.

And yeah I'd hate to be tracked and killed as you say. But then I picture being born in a prison and growing up to mid-childhood with the express purpose of being killed, and I know which one I'd pick.

The type of drones that are small and cheap enough to make a "swarm" lack the range to cross the Taiwan Strait.

The other end of the Church-Turing intuition is that if we couldn't possibly do it then the machines can't do it either. What they're doing is the same, it's not only not magically less powerful it's also not not magically more powerful.

You seem to be imagining that Gödel is just a small problem you can carve off and ignore, but it applies for everything powerful enough to do arithmetic.

Of course we can have the AI muddle along with intuition, but that's not actually an improvement, our mathematicians can already use intuition and they've got a lot more experience.

I am extremely disappointed at the replies from (some) experts. As a mathematician who has been worrying about the state of the literature for some time, I expected trouble like this---and expect considerably more, especially from the number theory literature between the 60s and the 90s. I also wonder how well 4-manifold theory is faring.

Much worse, this nonchalant attitude is being taught to PhD students and postdocs both explicitly and implicitly: if you are worried too much, maybe you are not smart enough to understand the arguments/your mathematical sense is not good enough to perceive the essence of the work. If you explain too much, your readers will think you think they are dumb; erase this page from your paper (actual referee feedback).

Also, like Loeffler in the comments, I don't trust the "people have been using crystalline cohomology forever without trouble" argument. The basics are correct, yes, as far as I can tell (because I verified them myself, bearing in mind of course that I am very fallible).

But precisely because of that, large swathes of the theory will be correct. Errors will be rare and circumstantial, and that is part of the problem! It makes them very easy to creep into a line of work and go unnoticed for a long time, especially if the expert community of the area is tiny---as is the case in most sub-areas of research math.
That should be prominently displayed on all AI products: "This service will lie, hallucinate, and make up facts in order to continue the ongoing conversation, and is in no way a real expert in any field".
The characterization of mouse keys as taking "five...more like ten seconds to get to where you want to go" is incorrect with a decent implementation/practice.

I exclusively use mouse keys with my QMK keyboard [1] and I'm just as fast with it as with a mouse. I have four different cursor speeds that I toggle between as I move the mouse: I use the SUPA FAST LIGHTNING SPEED mode to move across the sceen and then reduce the speed as I zero in on my target. It's totally seamless and easy.

I also happen to use Tridactyl which uses a very similar mechanism as mouseless, but sometimes when I'm lazy I just use mouse keys. I don't think navigating by key anchors is always better: there's a greater cognitive load to reading off characters and typing them vs. using WASD to move your mouse around.

Alternatively, we could all simply relent and accept the fact that this problem was solved long ago in hardware and ship TrackPoints on all keyboards.

I acknowledge that this is an emotional response and emotions tend to be blunt instruments that don't really come with detailed reasons.

> how can one, even in theory, make more and more money every year and remain positive for society?

Why is making "more and more money every year" the assumed goal and "remain[ing] positive for society" the thing we have to barter over? Why do we accept, as a culture, the idea of profit is more important that people? That's sad to me.

> Is everyone just doing something "wrong" here?

Maybe? Maybe we've created a culture that is fundamentally opposed to our overall well being? I think we have, at least in some respects.

To use your analogy, it's not so much that I am sad it rains sometimes. I'm sad that, knowing it rains, we are happy with companies that sell unsuspecting people homes in floodplains knowing there is a real chance that the inhabitants die in floods. Then when it happens the response is just, "well, that's just how it is, it rains sometimes."

"When the quasiparticles travel along one dimension inside the ZrSiS crystals, they do so at the speed of light and are therefore massless. But as soon as they try to travel in a different direction, they hit resistance, slow down and gain mass."

Just FYI you should avoid using the name Blender in your product

From https://www.blender.org/about/logo/

"In short – if you want to start a company or website related to Blender services, avoid using the name Blender in it. You can use it as a secondary tagline though – such as “Awesome Company Inc., the Blender specialists”. Same goes for forks of the Blender software, give it a new name and create a unique brand that way. The latter is also enforced by the GNU GPL, which explicitly excludes brand names from the freedom."

> a lot of hunters aren't doing it just for food, though the does have milder flavored meat.

I know both hunters. Some want the trophy, some want the meat. Those who want the meat prefer does if they can get them for the milder meat.

This is somewhat cultural though. I grew up in MN where limited amounts of doe permits were always given up - thus every hunter made sure they applied for the yearly lottery for doe permits and so a culture of hunters preferring doe meat when they could get it developed. Next door in Wisconsin they never gave doe permits and so hunters learned "don't shoot the doe, one buck surviving can breed it thus resulting in deer for next year's hunt". Now that population control is important MN had no problem giving out more doe permits, Wisconsin had to force the issue (no shooting bucks until you shoot a doe) as even when hunters were told they could shoot does they didn't.
I mostly agree with you but there are some caveats and it varies by location in the US. [1] While I am in one of the most firearm friendly states I will personally avoid 3D printed firearms until the federal and state laws are more clear and aligned. Aside from the legal ambiguity aspect I would want something battle hardened and pressure tested that I know won't blow up in my face.
