Goods question. I've been thinking about implementing this[1] method for real-time sound propagation as a hobby project, which relies on this[2] paper. Here's an excerpt from the second one:

In this work, we present a technique which relies on an adaptive rectangular decomposition of a 3D scene to enable efficient and accurate simulation of sound propagation in complex virtual environments. It exploits the known analytical solution of the Wave Equation in rectangular domains and is thus able to achieve at least an order of magnitude performance gain compared to a standard Finite Difference implementation, while also being memory-efficient. Consequently, we are able to perform accurate numerical acoustic simulation on large, complex scenes in the kilohertz range which, to the best of our knowledge, has not been previously done on a desktop computer.

Note on the performance claims, it's about a decade old.

Anyway, was looking for a reference implementation so also curious if OpenCFS could be it.

I've often considered writing the equivalent of a robotrader for this. If you're paying for a sedbox and want to use it to the fullest re: maximizing your ratio then some automated attempt to predict demand and start seeding the right thing early would likely go a long way.

Unlike predicting the stock market, competition wouldn't be very fierce, and I think the tracker API would give you most of what you need.

It's in the long list of things I'll do if I ever find a big pile of time.

>Later, during the 1920s and 1930s, Italian fascists and Nazi Germans adopted a salute which was very similar, which they attributed to the so-called Roman salute, a gesture that is wrongly thought to have been used in ancient Rome. This resulted in controversy over the use of the Bellamy salute in the United States. It was officially replaced by the hand-over-heart salute when Congress amended the Flag Code on December 22, 1942.

In other words, when people decided "fuck that, I dont want to look like a Nazi" they did something different.

Which is precisely why what Musk did was a Nazi salute. Because we know not to do them for fear of being mistaken for a Nazi. The deniability is implausible at this stage.
> Ketamine abuse is well known to cause widespread cognitive and neurological impairment. However, the average ketamine “user” consumes 500-1000mg of ketamine per day, which is a lot more than therapeutic use (0.5mg/kg). One glass of wine per week is surely different from a gallon of vodka per day.

So, Microsoft’s move to ditch leases for “a couple hundred megawatts” of data center capacity, as noted in TFA, is a pretty intriguing shift—and it’s not just a random cutback. Per some reports from Capacity Media and Analytics India Magazine, it looks like they’re pulling some of their international spending back to the U.S. and dialing down the global expansion frenzy. For context, that “couple hundred megawatts” could power roughly 150,000 homes, (typical U.S. energy stats) so it’s a decent chunk of capacity they’re letting go.

IMO it's not a full-on retreat—Microsoft’s still on track to drop $80 billion this fiscal year on AI infrastructure, as they’ve reaffirmed. But there’s a vibe of recalibration here. They might’ve overcooked their AI capacity plans, especially after being the top data center lessee in 2023 and early 2024. Meanwhile, OpenAI—Microsoft’s big AI partner—is reportedly eyeing other options, like Project Stargate with SoftBank, which could handle 75% of its compute needs by 2030 (per The Information report). That’s a potential shift in reliance that might’ve spooked Microsoft into rethinking its footprint.

Also it seems they're redirecting at least some costs - over half that $80 billion is staying stateside, per Microsoft’s own blog, which aligns with CEO Satya Nadella’s January earnings call push to keep meeting “exponentially more demand.” It’s a pragmatic flex—trim the fat, dodge an oversupply trap, and keep the core humming. Whether it’s genius or just good housekeeping, it shows even the giants can pivot when the AI race gets too hot.

Those sound like enemies within, but what do I know? Liberals / leftists / whatever have non-personal internal enemies (white supremacists, ultra right wing, nationalists, etc), and right wing have external enemies as well as entirely personal internal enemies too. Right wing certainly talks about moral failings.

Seems really difficult to quantify to the extent you can just say they don't. We can all come up with examples or handwaved anecdotes of any kind of enemy from any ideology really, so what actual metrics are you using to differentiate these things?
I don't know if you understand the concept of military enemy and how it differs from countries that are simply cooperating less...
Well it's a middle ground between two other realistic extremes, those being "subsystem maintainers must understand and support the Rust bindings to their APIs" and "subsystem maintainers can veto the introduction of Rust bindings to their APIs".

Sure, but you can't do that legally without an act of congress, and the DOJ only (in theory) prosecutes when laws are broken. Redefining what a monopoly is doesn't really help in a courtroom.
Over on Android it's the opposite situation. The voice interface to Google Assistant was very reliable for simple things like reminders and appointments, and even for general knowledge questions. It was part of why I didn't switch to an iPhone. Then Gemini came along, and that core functionality got a lot worse.
I've mostly seen language mixing in frontend. Backends seem to end up either being completely ported to a new (compatible) language, or experimental new languages get ported back. Perhaps frontend developers are just more versatile because they have to, with frameworks and the base spec constantly shifting under their feet.

Even many backend devs seem to shy away from things like SQL because they're not too comfortable with it. Which isn't bad per se, it's very easy to make a small mistake in a query that crushes the database, just a personal observation of mine.
total tangent, but i was doing just that (vscode + pi zero w) yesterday with my son. We used the Remote Host plugin to surface the file system on the pizero in vscode as well as a terminal. We were just writing python though, not anything that requires a build chain, but seems like you could still kickoff a build through the terminal.
Great concept! However my mind started already coming up with ideas how to circumvent this like printing out a color picture of grass! Hope you can detect these fake attempts! :)

The point is, you cannot rely on TTL. TTL could be hard coded on a server to 5 minutes or to 20 days. Doesn't need to be a BFE server, it could be a Comcast DNS for all you're aware.

This is why DNS "failover" is never a good idea outside of a highly controlled (i.e., internal) environment.
I'm not sure what you mean by "leaving place for". There was a place for Perl and Tcl on Unix. That's how we wound up with Perl and Tcl.

If you mean that C should have ceded all of user-space programming to Perl and Tcl, I disagree strongly. First, that position is self-contradictory; Perl was a user-space program, and it was written in C. Second, C was much more maintainable than Perl for anything longer than, say, 100 lines.

More fundamentally: There was a free market in developer languages on Unix, with C, Perl, Awk, Sed, and probably several others, all freely available (free both as in speech and as in beer). Of them, C won as the language that the bulk of the serious development got done in. Why "should" anything else have happened? If developers felt that C was better than Perl for what they were trying to write, why should they not use C?
1. RadiaCode is a repo for running IOT connected detectors from a specific vendor

2. Detectors are judged based on the mass and resolution. The resolutions for each vendor specific variant are at least 50-200% higher than what is possible with 'passable' material. Additionally the spectra shown indicate a very small detector mass, meaning these would not be much more sensitive than GM counters, and possibly less reliable in other metrics.

a. Why are the resolutions for CsI(Tl) 9.5% and not closer to 5%? (in this case, lower is better)

b. Are the sensors calibrated for temperature and other systematics? how long do the calibrations last and to what % of energy resolution?

c. Are the sensor responses linear? The documentation [1] shows that these can be very high error rates (up to 40% for "some isotopes"). Such high error rates makes this hard to see how dependable or useful the device would be.

From time to time I think most, ambitious, people fall into this trap.

The issue is that these are positional goods. Per definition there can only be a single person who is the top contributor of a field of research.

Every time I fall into this trap I separate out what is positional goods and what is valuables to me. And then I very deliberately convince myself that it is not worth it to chase positional goods for the sake of doing so.

Said in other words: Do research because you like it, not because of the acknowledgement that follows on.

(As a side effect many will find that they indeed do not care doo much about research)

> China is not right-wing. That's prerequisite.

Define right wing in this context. Its historically communist, but it not really so any more, as you your self admit "Control of the economy is limited and directed"

> China has nationalism, but is very much not ultra-nationalist.

It is very nationalist and believes its culture to be superior to minority culture which is why they are assimilating it.

> For Jews in 1930 Germany, assimilating was very much not enough to be left alone.

True, but I said "fascism" not "nazism" which are not the same thing.

> Rather, the state violence you see there is institutionalized violence, through proper administrative and bureaucratic channels.

is that a necessary trait? The Brownshirts were got rid of once the Nazis were in power. Once you control the state you no longer need the paramilitary.

> However, "fascist" is not the same as "totalitarian."

I agree, but I think China has a lot of traits in common with fascist states. it might not tick all the boxes in a definition, but it ticks far more than the typical dictatorship.
Uhm I think you misunderstood me. What I meant is that I love these trivial, fun, silly apps that make the internet more interesting. You can certainly sit and meditate whenever you want
> the use of the 'roman salute' term is (potentially accidental; I think maybe some people do think it was a real thing) sanewashing.

It's used because YouTube and tiktok will demonetized you for saying Nazi.

TikTok, in particular, has pretty aggressive live stream killing policies. It's lead to weird things like streamers saying "grape" for "rape" and "unalive" for "kill".

Ketamine is widely used and it's very difficult to find deaths. Sure, one can die by taking it and getting in a hot tub or using it with other drugs. But on its own its safety profile is better than acetaminophen.
There's a less commonly known feature of NAT (maybe called cone NAT or something), where the remote endpoints are not checked for incoming packets and connections. You communicate with trackers and DHT and as usual your outbound packets are mapped to some port. But everyone use sees your public IP and port and talk about your client using that pair. They then also communicate with you over UDP to your public port. As long as you have regular outbound traffic running through that mapping, NAT will keep the hole alive. I think with testing I found at least half of people on NAT had this. It's less common on mobile and fibre.
One part of the joy that came with using Clojure is that there isn't really any bad choice. For example, I wanted a quick and dirty internal web application for admin purposes. I went with reframe. Why? Because I wanted to try it. And I knew, that I could get things done with it.

This is probably not the easiest "framework" (not sure this is a good name for it) but it was very fun. I think, if I had to progress from just a toy to a really strong, user facing UI, I think it would still be a pretty good choice. If some feature is missing, or something doesn't work as I would have liked, I know it will not be difficult to correct it myself.

I know that this could feel overwhelming, but this is freedom in a world where you expect there exists a single "best practice". As long as the tool is powerful enough it will be fine. On my end, I appreciate the fact there is not a single "web framework" in Clojure. Instead you have tons of libs you can use that work well together because they are all tied with a few common concepts (like ring for example). If you don't like to choose the libs. There are a few people that provide a starter pack with somewhat nice bundle of libs in a single system like pedestal or luminus for only citing two of them.

My recommendation is to not lose too much time looking for the best choice. Most of them will be good.
Thanks!

... Oh interesting. And those concepts are hand picked or generated automatically somehow?

I think this is where the AGI employee succeeds where other automation doesn’t. The AGI employee doesn’t require the organization to change. It’s an agent that functions like a regular employee in the same exact system with all of its inefficiencies, except that it can do way more inefficient work for a fraction of the cost of a human.

The more apt framing of this article would be something along the lines, of "The Agency Trap." The author grew his marketing agency to $1M quickly. That might sound great for HNers here, but there are reasons why such businesses don't attract handsome valuations. You always have to keep grinding to keep the inflow of customers, you're never free, and growth is directly tied to the number of employees. Additionally, such business can have severe ups and downs depending upon market conditions.

Building a product, on the other hand, is slow at the start but after a point, the rewards start showing up. The inflow of cash is consistent and keeps growing while the costs remain the same.

There's nothing wrong with the agency business, but it'd be a smart bet to use at least some of the proceeds into building something long-term. Some agencies, notably 37signals, have been quite successful doing that. Most, though, never do it.
Dude; how can you say you are a failure in your early 30s? You have just finished being a kid and learned to navigate the adult work. You still haven't done anything worthwhile, and you're about to start. You have just finished the tutorial to life, and now are facing the question of now what?

Sincerely, a late 30s guy that has been through a massive burnout, mid life crisis and journey to discover myself in the past 5 years.

Millions of people have been through the same in the whole of history. Many have left notes about their experience for posterity. Time to hit the library, my friend.

(The things that have helped the most have been, in no order: talk therapy, solitude, the Tao Te Ching, Alan Watts, Camus, Nietzsche, and many more, rediscovering my long lost teenage dreams, understanding that nature is a crucial part to mental sanity and restoration)

Take care, and good luck.
Me too... Maybe that's why his note resonates with so many people
I think there's a simple issue to sum up the problem - implementation details should be hidden from the user. But AI systems that rely primarily on excessive cheating become a game where knowing their implementation is essentially 100% of the strategy because overcoming such an unfair gulf is basically impossible without breaking the AI. This lends itself to awkward strategies that should not work, but do. And it simultaneously also makes many aspects of the game basically red herrings in that they simply don't work. And that's seriously (!!!) a shame because the designers in Civ have done a great job of creating lots of really interesting systems, but these systems have gone far beyond the AI's capability, which is just compensated for by extreme cheating.

It can also lead to the appearance of buggy behavior if you don't understand the implementation. For instance I think Firaxis did a much better job of the AI in XCom (in that it's enjoyable to play against at least), but there too you kind of need to understand the implementation or you might wonder about why, for instance, enemies seem to be magically teleporting around the map. The answer, of course, is that they indeed are.

Of course creating a non-cheating AI that's competitive against skilled humans is extremely non-trivial. But if you at least work on improving the AI you can tune down the amount of cheating necessary to create a challenge, which means the experience can feel much closer to 'organic.'
Purely in my head. A new kind of ERP system. I'm tempted to start writing it in public to trigger debate. I don't really want to say what is novel about it exactly, but it would be very open.

Annual growth rates during the Industrial Revolution where way lower than 10%. In the 18th century it was well below 1%, during the 19th century it was on average at 1-1.5% (the highest estimates go up to 3% annual growth for certain decades close to 1900).[0][1][2]

Some regions or sectors might have experienced higher growth spurts, but the main point stands: the overall economic growth was quite low by modern standards - even though I don't think GDP numbers alone adequately describe the huge societal changes of such sustained growth compared to agrarian cultures before the Industrial Revolution.
