Awesome. Thanks for the feedback.

1. I understand the frustration. I haven't really done anything for speed and performance yet. It's really an MVP.

2. Good feedback. I'll see what others think as well. There is a bug currently. Each post should have a meatball menu where you can follow another contributor or publisher. It is missing on some cards. The Subscription button in the nav bar is to see a feed of only those you follow.

3. The CRED slider at the top of the Front Page, Bullpen and Cred Desk gives you the ability to filter out content not meeting a minimum cred percentile (different on each feed).

Again, appreciate the feedback.

The question is why "so many real-world systems are governed by differential equations" and "so many real-world systems involve periodic motion".

Well, stable systems are can either be stationary or oscillatory. If the world didn't contain so many stable systems, or equivalently if the laws of physics didn't allow so, then likely life would not have existed. All life is complex chemical structures, and they require stability to function. Ergo, by this anthropic argument there must be many oscillatory systems.
Show HN: OpenProfiler – An utility to view NHibernate's generated queries
by lpnam0201 | 2025-09-05 04:19:30+00:00
I used NHibernate at work, but sometimes it's hard to view the generated queries. (SQL profiler is a little hard to use and the queries aren't formatted. NHibernate Profiler is good but costs us too much money)

Therefore I spent the last few weekends writing a small utility to do that. You only need to add reference to the DLL and run your .NET app, it will output the query in the Profiler similar to how it's done in NHibernate Profiler.

I appreciate any feedback and suggestion. Thanks.

Shenzhen is not all futuristic blue all the time, as shown in the picture in the article. Most of those buildings have full RGB capability. Here's a drone video of Shenzhen at night.[1]

For the 45th anniversary of the Shenzhen Special Economic Zone last month, the building lighting and rooftop lasers were coordinated with a 12,000 drone show.[2] Mostly white, some blue tinge, red buildings on the more official messages. Not much green. That's Shenzhen looking futuristic on purpose.

I had a 48S then a 49g+. I played around with a few games and a Magic Eye style (https://en.wikipedia.org/wiki/Random_dot_stereogram) 3D image generator, as well as programs to do actual math in my math classes. The math teachers teachers at my high school had a policy that, on exams, students could run any program they wrote, so I wrote programs to do the math and "show my work". Solving equations on paper was half of the grade, and getting the correct answer was the other half, but my handwriting is really bad, so I'd always get the wrong answer if I did it by hand.

HP's calculators are pretty capable, with built-in commands for image processing, so RPL programs could rival the capabilities of assembly language programs on TI-8x calculators.

People are suggesting this to continuously monitor vitals. Others think that is a privacy problem. There might be an even bigger problem: continuous vitals monitoring might lead to over-medication and perhaps be worse for patients.

One of the reasons vitals are such a good diagnostic tool is that we monitor them specifically when we already suspect something might be wrong. Monitoring healthy patients reveals the large variation in vitals -- some that might even appear problematic.

We know this among other things because we have accidentally experimented on babies and mothers during delivery. Some clinics have a policy to put them on continuous monitoring the moment they arrive and they get treated for more things with worse outcomes when they're otherwise healthy. Maybe this is confounded (some clinics overmedicalise everything -- both monitoring and treatment) but I like the intuitive explanation that excess monitoring causes excess treatment.

Not having to go to a gas station ever is a paradigm shift that I think a lot of ICE owners underestimate. You're never late to something because you need to make a pit stop to get gas. If you always have your car charged at home, time to get places is much more deterministic. You also don't need to worry about CC skimmers, which at least where I live have been a pretty common problem off and on for many years.

Bucharest was a tanker that was not believed to carry nuclear weapons, and the public point of the blockade was to prevent nuclear weapons from being shipped to Cuba.

If Kennedy was a yellowbelly, what was a 'strong man' supposed to do in his place? End civilization over it?

Your hyperfocus on 'winning' every confrontation, no matter the value, and no matter the risk - is destructive and incredibly dangerous.

> U-2 plane was shot down and Maj. Rudolf Anderson has died

Could you remind us what that U-2 plane was doing, and where it was while doing it?

You can't honestly hold the Soviet bloc to blame for shooting down an enemy aircraft over its own territory... Or view Kennedy as weak because he didn't escalate over a clear act of self-defense.

They had every right to shoot him down, and everybody knew it.

My blue-collar journey with LLMs began Summer 2022, after watching Yannic's GPT 4-chan video [0] — visiting simple GPT-2 iterations (e.g. http://www.thisworddoesnotexist.com — which still exists and is a fantastic linguist's homepage — &al CRAIYON &c).

My most-shocking LLM interaction so-far ties with when http://www.perplexity.ai cited my recent wikipedia edit (from my two decade+ account) in answering a question about transistor density... less than one day after I had made the update it cited [1]. Like I am nobody why tf are you listening to me?!?

This ties with having sat with a published author of a non-fiction war chronicle as we discussed his books, himself, and his world (with a computer, me typing / brainstorming).

Among many other reconfigurations of muh'brain.

I never had Action!, but I did try Deep Blue C for the Atari 800. One issue was lack of brackets in the character set.. I think it used $( and $) instead.

There were some other weird 8-bit programming languages: PLM and MPL. These are PL/I clones for 8080 and 6800. I used MPL long ago and wrote an article about it:

PLM was much more popular and better:

It's not 0.8^10 anyway, because there aren't 10 neighbours.

There are neighbours in both directions in each dimension, i.e. 20 neighbours in 10 dimensions if you're allowed to wrap around the edges of the lattice.

With wrapping, I think the probability is 0.2 × (0.8^20) ≈ 0.002306 ≈ 0.23%.

If you're not allowed to wrap at the edges, a unformly random point has 2/N probability of having one neighbour on each dimension independently, and (N-2)/N probability of having two. With D dimensions, that's on average D(2N-2)/N neighbours.

With D = 10, N = 5, I think it's 16 neighbours on average, with a distribution from 10 to 20.

That makes the probability of landing on a mountain peak lower than ~2% and higher than ~0.23%. (Not 0.2 × (0.8^16) though, due to the distribution.)

It hasn't been effective for me. I've put up two bat boxes, and neither has had any tenants in the 8 months they've been out. There are plenty of bats around, maybe they've got better housing options. The ones I observe occasionally fly low to the ground and near the house (it's a thrill to get buzzed by one), but mostly they're further away and higher up and we still get plenty of bugs, including mosquitos in the house. Bats probably do help reduce the numbers, but all it takes is one mosquito to ruin your night.

Do you recall a couple? It's one of my minor hobbies when I'm bored to try to find sources and fix Wikipedia articles that others have trouble with. As examples that this is a good faith attempt and not the usual online comment technique of "oh yeah? show me!", here are some stories of edits I got in that others said they had trouble with:

- https://wiki.roshangeorge.dev/w/Blog/2024-10-17/Path_Depende...

- https://news.ycombinator.com/item?id=40655989

- https://en.wikipedia.org/wiki/Talk:Weierstrass_function#Accu...

And my personal favourite is recently when the most ridiculous thing was added to Bukele's Gang Crackdown: https://en.wikipedia.org/w/index.php?title=Salvadoran_gang_c...

If you still have the desire to have some of these fixed, post here and I'll put it in my queue and get to it at some point. If you don't want the resulting interaction from other commenters here, send it to my email (in profile).

Wikipedia is ultimately a consensus summarizer frequently mistaken for a truth-seeker. So you have to make the case for something being true somewhere where the experts live, and then Wikipedia can express the experts' opinion. But crucially, it is not truth-seeking on its own.

Have you tried Lazarus (https://en.wikipedia.org/wiki/Lazarus_%28software%29, https://www.lazarus-ide.org/)? When doing something for the fun of it, I would much rather work with Pascal than Python. Both languages were developed to be quick and dirty, but I feel like Pascal is more on the quick side, and Python is more on the dirty side.

Person A deposits $100.

Person B borrows $100, all the coins move on the ledger.

The ledger could facilitate the transfer while the bank maintains an "IOU" for person A's $100. The bank would be betting that not everyone will come withdrawing at once, just like a regular bank.

Regulation is the only thing that can prevent this from being done with any sort of crypto. The same IOU-based business model as happened with cash, gold, etc, could very easily be implemented using the technology. If you don't like fractional reserve banking crypto isn't a magic bullet that makes it impossible, especially since the general public probably wouldn't be sophisticated enough to know how to stick to "true" crypto vs "IOU-based fractional crypto facades."

But generally regulatory regimes have decided that the productivity advancements offered by the investment-through-loans of major portions of deposits are worth the risks. I don't think the GENIUS act allows this, though, so there's one regard where stablecoins are more-regulated. I worry about the edge cases, though - seems like requiring stablecoins to be paid off preferentially incentives using them for deposits, which could harm circulation if the reserves or followed, or which could screw over non-stablecoin deposit-holders if an institution doesn't comply and then goes under.

(This is closer to how regular banking works than the naive "banks create money by incrementing a number in your account." After all, banks are generally either (a) expecting those loans to be spent or directly giving the money to third parties like car dealerships or home sellers - which is likely to physically move the money to other banks, institutions, or cash, not just recordings in their internal tables.)

This is how I started working out regularly. "I can quit 5 min after warming up".

Five minutes after warming up I've changed, in the gym and a couple of sets in. I quit maybe 1/20 sessions, and it's shrunk more over the years since, but it was an easy way to fool my brain.

I'm guessing this is different because the main threshold is starting to do the thing. Once you've started it's much less mental effort to keep going and just do the full workout.

It may differ depending on countries, but I tried sending $8k USD to Malaysia and it took some time. Can't remember if it was weeks or days but point being it wasn't as instant as crypto can be.

Also, I think you're neglecting to point out the rigmarole involved with making a Wise account — connecting your bank accounts etc. And the recipient might also need a Wise account for instant transfers (but I believe Wise becomes a custodian for your funds in that case).

Crypto wallets can be generated by the click of a button. I think I taught my mom how to make a crypto wallet at some point. She didn't understand how to keep her crypto safe, which is its own issue, but wallet creation is easy.

I'm far from a crypto maximalist, but nigh-instant transfers with very little fee is a very attractive benefit of crypto.

Question (You may or may not have insight): What happens when I download a playlist and listen to it offline in my car on an hours long roadtrip? Do my “streams” get counted once I get back online? Does the artist get credit for an estimated number of streams based on typical patterns? Does the artist get bupkis since I might play a song ten times but it wasn’t technically streamed to me?

Unbelievable.

If nothing else, if this was truly “open” then whatever bullshit training or certification would just be released into the public for people to reference at-will.

So now there’s going to be some database of “you passed our certification to use our tool” essentially creating an in-group and an out-group.

All this because “you’re holding it wrong, clearly the problem isn’t us, it’s you people”

This is dystopian.

You can download an MP3, but you still don't "own" it in the conventional sense. You are licensing it, and a downloaded MP3 is how you utilize that license. If that license was revoked for some reason (admittedly not a likely scenario), continuing to have the MP3 on your system would be a violation.

In practice I doubt this would ever be an issue, but just wanted to point out that you effectively never "own" a digital reproduction of something unless you are the actual copyright holder (or the copyright is permissive), and digital copies can be clawed back in a way that a CD or physical book you purchased cannot.

Yes there's something inherent. Namely this: the ability to drop all sorts of requirements off the table, yet still call it some kind of Lisp.

It does not need to be compiled to be a Lisp. It doesn't need arbitrary precision integers. It doesn't need hash tables. Garbage collection doesn't have to work; it can just run out of space and terminate. It can just crash on errors without a trace. It doesn't need to report the line number where a syntax error likely began. You get the picture.

Yeah UE GC safepoints at end of tick where there is no stack. That’s a common trick in systems that have both GC and ticking.

To be fair, FUGC doesn’t currently let you do that. The GC runs in a separate thread and soft handshakes at various points, which cause your game thread to react at poll checks and exits that might not be at end of tick.

But I could add a feature that lets you to force handshake responses to be at end of tick! That sounds like a good idea

I've spent plenty of time counting cash and filling out bank deposits, but it was a volunteer position, so we did everything by hand. It's pretty error prone, but we only had to do it once if the cash matched the receipts, which it usually did.

Bill counting machines start at less than $100, and they make it super quick, so accuracy and handling time isn't really a problem any more.

Most retail theft is of inventory, not cash, and chargebacks will easily surpass lost cash anyway.

I dunno, I’d assume it is projecting your own inability to separate analysis of basic definitions and facts (the question of “in law, are any or all of copyright infringement, piracy, and theft literally the same things?”) from personal political preference (“is rigid adherence to the wishes of the copyright owner desirable for commercially licensed music? is rigid adherence to the wishes of the copyright owner desirable when that is adherence to the terms of a copyleft free software license preferred by the FSF?”) combined with you being really bad at guessing other people’s political opinions (“is dragonwriter a zealous proponent of the FSF in particular or copyleft licenses in general?”) even in a forum where those opinions are on full display?

No dig, no service boxes in front yards, under someone's unpermitted driveway pour, ample power easily, a guy in a bucket truck is all you need.

You can check all the teams and their members here: https://cphof.org/advanced/icpc/2025

It's rarely the case that looking at school names is useful (for many things in life) when there are more data points.

In this case, without any insider knowledge, just by looking at their profiles, the relevant name would appear to be Benjamin Jeter (https://codeforces.com/profile/BenjaminJ) rather than ASU. Currently 5th active American in the top competitive programming platform, top 200 worldwide (https://codeforces.com/ratings/country/United%20States). That's elite.

In teams of 3, even one "super player" can make a big difference. Almost certainly carrying that team.

Creating a crypto wallet to receive is just the first step though. If your mom needs her local currency then the same as with wise she needs to create an account on some form of exchange or pay an extortionate rate to use a crypto ATM.

If she doesn't need that then wise without a linked account or PayPal or etc is the exact same outcome without the crypto wallet security risk.

> given that pointers can be converted to integers?

Because if they get converted to integers and then stored to the heap then they lose their capability. So accesses to them will trap and the GC doesn’t need to care about them.

Also it’s not “Dijkstra accurate”. It’s a Dijkstra collector in the sense that it uses a Dijkstra barrier. And it’s an accurate collector. But these are orthogonal things

That's actually the same as Java, with its "checked exceptions" (aka listed in function signatures), and the RunTimeException hierachy which don't have to be listed.

In Java common errors and exceptions, like file I/O errors, have to be declared on each function signature, except everything under the RunTimeException hierachy is exempt from this requirment. In the language, RunTimeExceptions these are the messy errors like NullPointerException and ArithmeticException.

In practice, people do subclass program-specific exceptions under RunTimeException in Java, as well as wrapping existing exceptions inside a RunTimeException, for the sole purpose of not having to add them to function signatures all over the place.

I don't think that logic checks out. It being "slower, riskier, with less protection and usually more expensive" are not properties that self selects for criminals.

Stablecoins typically being self-custodial, easier to transfer in large amounts, and internationally accessible seem like it would support criminals, but with stablecoins, funds can be frozen just like bank deposits can.

This is emphasized in the article you linked:

> The investigation began in late 2023 when Tether, the issuer of the USDT stablecoin, proactively froze 39 wallet addresses containing $225 million in stolen USDT after detecting suspicious activity. This immediate action was critical in preventing further dispersion of the illicit funds. Paolo Ardoino, CEO of Tether, was quoted as saying, “Tether’s work with the Department of Justice underscores our commitment to transparency, proactive engagement with law enforcement, and the protection of users across the digital asset ecosystem.”

And the number you quoted is for cryptocurrency at large, not stablecoins. I imagine the number looks a lot different when we filter for that subset of usecases. For the large amounts used in stories like this, banks would be a better indicator for comparison[1][2]. Venmo, Cashapp, and Zelle have had their fair share of scandals as well[3].

Applying FT to images is a great way to see the world very differently, as if through an alien's eyes (or Geordi's visor from ST TNG!). A kind of stimulated out-of-the-box thinking. Dense features like fur or hair manifest as high-frequency components and eventually you start to develop an intuition for their patterns in the magnitude / power spectrums.
