Your wife is living vicariously through the kid, in more ways than one.

That’s good - but only to an extent, like you’ve both identified in the past.

They need to seek their own hobbies and interests to fulfill their dopamine needs, and give themselves purpose besides dictating who the kids end up being.

Coming from the other direction: you could reclaim some of that time for the kids (take over pageant time and now that’s when we go to the trampoline place with you).

Don’t let your partner run further away from you! Have a chat and reign this thing in.

There’s at least one stranger rooting for you.

It's true that these patterns and problems have existed and will likely continue. It's also true that common rhetoric and bias have changed dramatically in the last 10-15 years. I don't forsee any simple or easy ways to replace the social and political dams that tamed the pressures of power. It's very difficult to make power useful instead of destructive and it's very unlikely that this entropy will reverse. It's also illogical to do nothing about it.

I’m puzzled by the limited opposition from businesses regarding government attempts to access encrypted communications. Granting governments easy access—which inevitably leads to uncontrolled monitoring—compromises a company’s most valuable asset: its privacy. This would effectively hand over the keys to their operations, exposing them to security breaches, stifling growth potential, limiting access to competitive markets, and ultimately, jeopardizing company ownership. Corrupt officials could exploit this access to manipulate markets, facilitate insider trading, sabotage business plans, and even plant fabricated evidence within company communications and systems, leading to potential takeover and imprisonment of owners.

Only true for our current computers and not true with reversible computing.
With reversible computing you can use electricity to perform a calculation and then "push" that electricity back into a battery or a capacitor instead of dumping it to the environment.
It's still a huge challenge, but there is a recent promising attempt:

"British reversible computing startup Vaire has demonstrated an adiabatic reversible computing system with net energy recovery"

While RLVF is neat, it still is an 'offline' learning model that just borrows a reward function similar to RL.

And did you not read the entire post? Karpathy basically calls out the same point that I am making regarding RL which "of course can be exploited to help move the needle on benchmarks":

> Related to all this is my general apathy and loss of trust in benchmarks in 2025. The core issue is that benchmarks are almost by construction verifiable environments and are therefore immediately susceptible to RLVR and weaker forms of it via synthetic data generation. In the typical benchmaxxing process, teams in LLM labs inevitably construct environments adjacent to little pockets of the embedding space occupied by benchmarks and grow jaggies to cover them. Training on the test set is a new art form

Regarding:

> I really don't know how to reply to this part without sounding insulting, so I won't.

Relevant to citing him: Karpathy has publicly praised some of my past research in LLMs, so please don't hold back your insults. A poster on HN telling me I'm "not using them right!!!" won't shake my confidence terribly. I use LLMs less this year than last year and have been much more productive. I still use them, LLMs are interesting, and very useful. I just don't understand why people have to get into hysterics trying to make them more than that.

I also agree with Karpathy's statement:

> In any case they are extremely useful and I don't think the industry has realized anywhere near 10% of their potential even at present capability.

But magical thinking around them is slowing down progress imho. Your original comment itself is evidence of this:

> I would strongly caution anyone who thinks that they will be able to understand or explain LLM behavior better by studying the architecture closely.

I would say "Rip them open! Start playing around with the internals! Mess around with sampling algorithms! Ignore the 'win market share' hype and benchmark gaming and see just what you can make these models do!" Even if restricted to just open, relatively small models, there's so much more interesting work in this space.

If you're interested in the large codebase... The best I found so far are extended context models.
Using newest Nemotron3 nano, you can put a 1m tokens (about 3 ish megabytes of text) of pure code dump (I use repomix --style markdown) and ask around.
That's been one of the biggest wow moments I had with LLMs so far. Much better experience than any RAG I used

> You will have a switch at home (perhaps in your router) with more than two ports on it. At layer 1 or 2 how do you mediate your traffic, without CSMA? Take a single switch with n ports on it, where n>2. How do you mediate ethernet traffic without CSMA - its how the actual electrical signals are mediated?

CSMA/CD is specifically for a shared medium (shared collision domain in Ethernet terminology), putting a switch in it makes every port its own collision domain that are (in practice these days) always point-to-point. Especially for gigabit Ethernet, there was some info in the spec allowing for half-duplex operation with hubs but it was basically abandoned.

As others have said, different mechanisms are used to manage trying to send more data than a switch port can handle but not CSMA (because it's not doing any of it using Carrier Sense, and it's technically not Multiple Access on the individual segment, so CSMA isn't the mechanism being used).

> That's full duplex as opposed to half duplex.

No actually they're talking about something more complex, 100Mbps Ethernet had full duplex with separate transmit and receive pairs, but with 1000Base-T (and 10GBase-T etc.) the four pairs all simultaneously transmit and receive 250 Mbps (to add up to 1Gbps in each direction). Not that it's really relevant to the discussion but it is really cool and much more interesting than just being full duplex.

Yes, as I mentioned, it should be kept around for this but off by default. Make it a sysctl param, done.

Only because it's on by default for no real reason. I'm saying the default should be off.

Seen a few. Enjoyed fewer. The ugly sisters strip tease through about 10 layers of underwear with more and more salacious jokes on their voluminous bottoms probably the best.

I hope somebody reviews "the gang show" which I suspect is past it's use by, we're saturated with talent shows online.

The culture which kept "down at the old bull and bush" alive on TV up to the 80s has a lot to do with this. We ditched harlequin despite it lying at the heart of panto, and kept the dance numbers.

Americans should try living in another country for a while. You don't need to worry about school shootings when you send your kids there in the morning. You don't need to worry about getting shot up in the neighborhood restaurant. You don't need to worry about protests turning into into little armed street wars. You don't need to worry about the cops shooting you dead because they're so worried that you may be carrying concealed arms. Life happens on a different gear. You'll certainly gain an appreciation for gun control and how noncontroversial it is.

Author here. We built a pipeline that turns policy prose into structured, executable rules + test cases (“policy → tests”), so governance can be enforced and measured in CI/CD / guardrails rather than living in PDFs. The paper walks through the DSL + evaluation and what broke / what worked. Feedback welcome, especially from folks doing policy-as-code / OPA / AI eval

> Every time the LLM is slightly off target, ask yourself, "What could've been clarified?

Better than that, ask the LLM. Better than that, have the LLM ask itself. You do still have make sure it doesn't go off the rails, but the LLM itself wrote this to help answer the question:

### Pattern 10: Student Pattern (Fresh Eyes)

*Concept:* Have a sub-agent read documentation/code/prompts "as a newcomer" to find gaps, contradictions, and confusion points that experts miss.

*Why it works:* Developers write with implicit knowledge they don't realize is missing. A "student" perspective catches assumptions, undefined terms, and inconsistencies.

*Example prompt:*
```
Task: "Student Pattern Review

Pretend you are a NEW AI agent who has never seen this codebase.
Read these docs as if encountering them for the first time:
1. CLAUDE.md
2. SUB_AGENT_QUICK_START.md

Then answer from a fresh perspective:

## Confusion Points
- What was confusing or unclear on first read?
- What terms are used without explanation?

## Contradictions
- Where do docs disagree with each other?
- What's inconsistent?

## Missing Information
- What would a new agent need to know that isn't covered?

## Recommendations
- Concrete edits to improve clarity

Be honest and critical. Include file:line references."
```

*Uses cases:* Before finalizing new documentation, evaluating prompts for future Agents.

>> banning future drones

It is about money. If they ban drones that are already inside the US, they risk lawsuits by drone owners/importers for expropriation of their property. Banning things that are not already inside the country is easier as nobody has an absolute right to import stuff.

It is akin to weapons bans. Banning future sales of machine guns is far far easier to implement than outlawing those already sitting in gun cabinets across the country. The former is free to implement, the later very expensive.

Perhaps if tip speed is X and radar installation is perpendicular to wind turbine, then an enemy can approach at speed X in the turbine's radar shadow. There would still be multiple pulses with timing differences but if there's a field of turbines then I'd guess there's enough interference/scatter to be a problem. Like using approaching from the sun causes problems for pilots.

The reflections from the turbines would pulse due to the blades so in theory their scatter could be cancelled out in processing?

> were because something was not right in my life.

THIS! Thats the reason why I always refused to take any medication: Doctors said you could "try X or Y and in some days I should feel better" - while the problems where mainly because of problems at work or within relationship.

Why should I take medics if I have problems at work with bad colleagues? This logic never made sense to me.

And my 2ct: If this wouldnt be a hardcore capitalist society in which most people struggle despite the fact living in a rich country, possessing nothing and having no homeownership, then there would be near zero demand for any psy medics.

Beyond some size, antique items become less valuable, because of the sheer headaches of moving and storing them. This thing qualifies. Antique Teletype machines are not very expensive. People have bought Linotype machines for $200. Trying to find a home for a locomotive is very tough. (When the Pacific Locomotive Society lost their lease at Hunter's Point Naval Station, they had a big problem. Most of their fleet is now stored at Brightside on the Niles Canyon Railway.)

I had the misfortune of working with the Xilinx Vivado environment, it's a fucking garbage, the software is straight out of the 90s, everything is glued together with shell scripts and the TCL scripting language, the IDE throws thousands of warnings and errors while building a sample project, the documentation is missing or spread over 150 PDFs, if the manufacturer of your evaluation board prepared an example for the previous version of Vivado, you must have two installations, which is probably about 2 * 100GB, if you want to keep anything under version control, you have to use some external tools, it's all absurd.

As an immigrant (I immigrated to Hong Kong)，I disagree when It comes to road safety. I believe that it's the responsibility of every driver to learn the differences when driving and until then practice safe defensive driving.

I agree with you that it takes a while to adapt to new sociale mores and it's worth cutting immigrants some slack but that's different from driving a multi-ton heap of metal where safety is important.

Sidenote: Of the different cities I've lived in Asia, HK drivers are some of the worst. Combination of aggressive driving with refusal to signal their attention (by using their turn signal) makes for very poor driving. Not everyone but a significant percentage.

Should I assume that breaking up google is bad for YC? And not breaking up google is good for YC? Why? Like having Google around would increase business opportunities for YC funded startups? And therefore HN mods are grifters in bed with trump? Sorry my friend but this is simply an insane

And even if breaking up google actually hurts YC, if one admin is reversing literally everything from the other admin out of princple and this accidentally does some good for you it doesn't mean it's friendly to you.

Ask HN: Is there a market for buying/selling Substack publications?
by iamevandrake | 2025-12-23 07:01:56+00:00
I’m exploring whether there’s a real market for buying and selling Substack publications.

Substacks increasingly look like small businesses: they have email lists, recurring revenue, retention metrics, and audience trust. But unlike micro-SaaS or content sites, there’s no obvious place to sell one if you’re done running it.

I’m curious:

Would you ever sell a Substack you built but no longer want to operate?

Would you buy one rather than start from zero?

What would make this feel legitimate vs sketchy?

I’m not pitching a finished product yet, just trying to understand whether this is a real asset class or a dead end.

Appreciate any thoughts, especially from people who’ve bought/sold small internet businesses before.

I have to say that that "surprisingly simple" thing is happening more and more for me on NixOS as well.

Recently a customer wanted me to use Fedora (I never visited the RPM side of the world before), and after truly the worst installer I've ever used, the actually system was nice. I do like Cockpit.

But then I needed to install an initrd that would me unlock the full disk encryption via SSH (it's a remote headless box). It took me half a day and a forum post to get it to work. I wrote a full page of notes for next time. Then the Firewall: I hit a bug (plus user error) which left me wrestling with a non-existent Tailscale interface for a while (it warns you for non-existing interfaces, but not with only a case mismatch, it then lets you do everything as if the interface exists), but after some hours I was done setting the zones, another page of notes and commands to enter to get to the desired state.

These configurations are both 1 or 2 lines in a NixOS config file. And that "work" is now done for all my NixOS servers.

You could argue that NixOS hides a lot of complexity, but so do Dracut and Firewalld of course. Nix is difficult, it's a high level abstraction. But it also just a bunch of key-values, and write-once, deploy everywhere.

Jetbrains is unforgivable for missing the remote development train. People have been developing on remote huge machines for decades. It’s just the ones who did either were terminal wizards, or they were using hacks to make their IDEs tolerable.

VSCode just scooped up that market with their remote development plugin. And it did not matter that it is an electron app. Still faster than Jetbrains.

Despite the amount of sucking up to Trump in the press release, this is not totally stupid. DJI drones do have a data path back to China. Several years ago, the US military, which used to use some DJI drones, decided that the risk was too high. There was an order (in 2022?) to cease using DJI drones and to store them with the batteries removed.

On the other hand, Donald Trump Jr. recently acquired an interest in a US drone company, which is selling drone motors to the US military for what seems a high price.

This architecture does not allow later layers to directly query KV data from earlier layers. Each iteration of the loop uses the same layer parameters, so the KV data in later layers may well end up being the same, but only if the model stops changing it in response to other tokens in the context. Which is also something a traditional multi-layer transformer could do. (But might not end up doing due to lack of corresponding inductive bias.)

None of this helps with the strawberry problem, where the very first layer already gets a tokenized representation, so there is no layer that "actually perceives those Rs."

Oh I see okay yeah.

Used to have one electric car but it was on a separate meter with unlimited charging for $40/mo (just looked, now its $46). Added a few hundred to the charger install originally.

We really don't do too much around the house. Three people. One TV running maybe two sometimes. Two desktops (well one is laptop with a dock). A random PC as a server. Everything electric (oven, range, water heater, filtration, etc) besides furnace (nat gas), although I will say they are all new and pretty energy efficient. Random lights (all LED, Hue). Someone turns on an electric heater or blanket here or there. Some outside heated cat house and water heaters and stuff. In Michigan so its pretty cold right now.

I recently bought a bunch of (used) solar panels and was doing our load calculations for peak draw and selecting battery size.

How much of your usage is the car? I could imagine that would be a lot. A single model 3 refill (57kwh) would be almost 5 days of my usage.

edit: I'm dumb. We replaced our electric water heater a few months ago with a tankless gas. I don't feel like rewriting this reply but just keep in mind.

I would eventually like to replace the furnace and the water heater with electric so I can end gas service to my house. I do feel its the safest and in the future we will be looked back on as backwards. "They used to pump a flammable gas directly into their houses!"

And there was a solution available. AdBlue. Mercedes already used it, and so did BMW. But VW didn't want to use it.

And because of this scandal VW pulled their diesels, AND both Mercedes and BMW followed suit.

Quite sad, because an X5 diesel had really good mileage (if you used it for longer distances).
