My comment was too snarky. I take your point. Based on the discussion this capability is closer to a really cool automated asset pack than "building 3D worlds". My understanding of world modeling is towards AGI, and you're saying nobody implied this is world modeling.

You're right. But the criticism is that it's closer to 2D asset packs than it is to 3D worlds and you're being overly charitable to Meta and underly charitable to the community response.

edit: this is just my over sharing of why i downvoted you. I didn't intent for you to feel dismissed.

The comment at the bottom of the article I believe is correct. I believe this because our neighborhood had the same problem. One day my neighbor, frustrated beyond his capacity, and seemingly very high on something, went outside and started ripping infrastructure out by hand and damaging everything else he could find with a hammer.

They came out and replaced a lot of the damaged equipment and did a few upgrades. After that the intermittent 2 minute drop problems disappeared.

>You can fit more into a larger terrarium, but that doesn't require a larger terrarium to contain more. Regardless of what is contained within the terrarium, it's heat production is limited by what it receives from the environment.

Go make a pile of mulch and monitor the temperature at the center. You will find that after a while it is hotter than ambient by a large margin because it is generating heat. The more mulch you permit to decay, the more heat will be generated.

>Greater atmospheric depth affects heat transfer by changing the density of the atmosphere

Greater atmospheric depth affects heat transfer by increasing the chances that an outbound photon of black body radiation hits a molecule that will absorb it and later re-emit the energy as black body radiation in a random direction, only sometimes still in a direction that will escape. It’s true that increasing atmospheric density will increase the chances of an outbound photon being absorbed, but so will increasing the distance the photon has to travel through atmosphere of any given density. The deeper the bubble of air, the more re-absorption.

I assume this is why an alloy of lead is used in practice. Still doesn't change the fact that graphite is a moderator not a shielding material. Also, structural materials in reactors are usually invisible to neutrons and a sandwich of materials is often used. Different layers do different things. Usually, one layer of shielding and one layer of a material that isn't impacted (much) by neutron flux for structural strength.

There is a rabbithole for almost all of these material choices, especially in nuclear. Not going down that rabbithole in a discussion targeted at folks who don't spend their lives working in nuclear doesn't make that person wrong. It makes them an effective communicator.

PS Lead is a very very common shielding material in nuclear.

Great memories, I worked for a CAD/CAM company at the time.. as an intern. One of the problems they had was that they did not want to ship demoes of their system to certain countries as they had seen code be reverse engineered and stolen. I made a demo suite that allowed for 3D renders to be played back in vector mode from the internal 4115 memory. The feedback we got from the main office in England was not good: the demo made it seem that the system was capable of creating real-time rotation views of complex models. Well, yes, it took several days to compute all frames but once I had the vectors the 4115 could show the frames at incredible speed.

They flew me to headquarters to explain how I got that to work and potentially incorporate a demo module into the system. Company went sideways after that, I ended up in Cambridge at another startup in a similar but different space, they used Sun Workstations ! Good days.

> Removed SD card. The manufacturer of the camera had requested certain components of the device be redacted. Portions of this image have been redacted.

And so it is, but anyone who has ever seen a Sandisk SD card knows what they're looking at. I can even tell it's not the fastest V90 speed.

The things companies try ineffectually to keep out of public view are weird.

Reading Jonathan Haidt's 'The Anxious Generation' broke me. I have two kids, still far too young for smartphones, but his book and all of the surrounding research has made me DRASTICALLY alter the way I use my own smartphone and will shape the way I treat phones with them.

If you have kids, take the "wait until 8th" pledge: https://www.waituntil8th.org/

No smart phones until after 8th grade.

For somebody substantially more productive checkout Leonhard Euler. Pronounced (oiler).

* https://www.youtube.com/watch?v=qtkX18dU2_U

I don't know if he had access to, or consumed, tea or coffee. He lost his eye sight due to a progressive illness and the more his vision declined the more productive he became. He is commonly considered the most accomplished mathematician in human history.

Thank you for the conversation.

The first 3 links you’ve provided discuss mental health as it relates to geography, not religion. To be sure, religion is associated with those geographic areas, but so are numerous other factors like race, income, etc etc.

The next links are closer to target, they talk about religious objections to medical treatments and the adverse affects upon kids. Nobody should deny this is a real problem, but fortunately it is a very small problem. ( One of the studies found only 172 fatalities over 20 years, and even estimated 10% of the kids may have died anyway.). So I’ll grant that is a real problem, but not one that affects many people. With luck, perhaps it will get better over time.

The next study is interesting, but again very limited. It has 6k subjects, but these are only with religious mothers and only in the UK. This study cites prior study that concluded “ an individual's religiosity is consistently, positively related to their own mental health in US samples”.

The next study associated suicidal tendencies with a very narrow aspect of religion, and even then self reported: “We recruited a relatively small sample that was geographically, racially, and socioeconomically homogenous. We also relied solely on self-report data.”

The next study does not seem to help your argument. It deals with religious beliefs in cancer patients and says “Higher levels of religiosity and spirituality are associated with reduced risk of suicidality and suicidal behaviors [29–31], including in advanced cancer patients “

The final link is just a case study about a single suicidal pastor. It concludes with a paragraph that says “Although there are studies showing that religious people are less prone to suicide…”

So I can’t say all that changes the findings of the many studies that conclude religion is good for mental health.

For JSON I agree, now I can just mention JSON and provide examples and the response always comes in the right format, but for tool calling and information retrieval I have never seen a system actually work, nor in my tests have these worked.

Now, I'm open to the idea that I am just using it wrong, but I have seen several reports around the web that the most that people got in tool calling accuracy is 80%, which is unusable for any production system, also for info retrieval I have seen it lose coherence the more data is available overall.

Is there a model that actually achieved 100% tool calling accuracy?

So far I built systems for that myself, surrounding the LLM, and only like this it worked well in production.

It reminds me of Bujold.

“Oh, certainly, you could produce quantities of infants — although it would take enormous resources to do so. Highly trained techs, as well as equipment and supplies. But don’t you see, that’s just the beginning. It’s nothing, compared to what it takes to raise a child. Why, on Athos it absorbs most of the planet’s economic resources. Food, of course — housing — education, clothing, medical care — it takes nearly all our efforts just to maintain population replacement, let alone to increase. No government could possibly afford to raise such a specialized, nonproductive army.”

Elli Quinn quirked an eyebrow. “How odd. On other worlds, people seem to come in floods, and they’re not necessarily impoverished, either.”

Ethan, diverted, said, “Really? I don’t see how that can be. Why, the labor costs alone of bringing a child to maturity are astronomical. There must be something wrong with your accounting.”

Her eyes screwed up in an expression of sudden ironic insight. “Ah, but on other worlds the labor costs aren’t added in. They’re counted as free.”

Ethan stared. “What an absurd bit of double thinking! Athosians would never sit still for such a hidden labor tax! Don’t the primary nurturers even get social duty credits?”

“I believe” — her voice was edged with a peculiar dryness — “they call it women’s work. And the supply usually exceeds the demand — non-union scabs, as it were, undercutting the market.”

> Whatever the safe level of smartphone usage is, most of us are above it.

I think I'm immunized from it because I hate using smartphones, especially when I'm at home and could be doing the task on a PC with a big screen and keyboard. I have a few but just use them for practical tasks when away from home (occasional text, deliveries on porch, looking something up in the store, listening to podcasts, to do list for the day). Viewing content on a tiny screen with a minefield of things to accidentally tap? No thanks. They are great multi-function devices to replace others on the go.

This research has nothing to do with wealth inequality or homelessness. It's simply documenting that young children form attachment bonds with consistent caregivers, whether that's mom, dad, grandma, or a stable daycare worker. The key word is stable. Kids need predictable, responsive caregiving from the same people over time. That's basic attachment theory, not a political statement about economic systems.

I wouldn’t say I felt better.

Which is why I found it so comparable to quitting smoking.

A smoker doesn’t feel “better” after quitting smoking. Even over a decade after having quit I bet if I smoked a cigarette right now I would feel much nicer than I did right before I smoked it. However, I would notice physiological changes, like a faster heart rate, slight increase in jumpiness, getting upset sooner, etc.

Quitting FB was similar. I didn’t feel “better”, but several psycho-physiological aspects of my body just went down a notch.

I am lucky enough to get regular palpitations. I read that caffeine can make them worse, so I stopped for a few months. They got worse. Talked to my Dr about it and he said yeah, sometimes it doesn't work like you'd think.

(Along the same lines, actually, I also made my palpitations much worse this year by dramatically improving my physical fitness. Turns out that slow heart rate for me means more palpitations. Heart rates above ~70 means almost no palpitations. Something about overdrive, but I am not an expert.)

So at least I don't have to give up my caffeine ;-)

I don’t think that’s a very good comparison.

Intel and AMD have to maintain compatibility in a much different way. They don’t control what is done on the OS, they don’t control what is done with the physical product sold in stores. They have gigantic customers like Dell and HP and Microsoft that make specific technical demands out of their architecture.

Apple controls the whole stack. They decide exactly what features are in software and are in hardware. There are zero Apple machines in data centers running BigCorp’s legacy CashCow software. There are zero laptop or desktop OEMs that use Apple’s chips besides Apple. Apple won’t piss off their core consumer or creative professional customers by changing some technical behind-the-scenes feature.

I think Apple would gladly cut a very small and specific architecture feature from their chips if they feel it’s obsolete, better accomplished in software or not at all.

And this isn’t just for cost savings, it could be for performance and/or battery life optimization, or to make room for something else in the package.

This is a little puzzle game I made based on Wolfram's rule 30[0]. I was doing some sketches based on old Genuary[1] prompts and for some reason this idea stuck with me, so I polished it up into a hopefully playable state.

I wanted to keep things minimal, but as a semi-easter egg you can play custom variants using url parameters like https://demos.samgentle.com/wolfrominoes/?rows=20&rule=110

True PXE doesn't require coordination with the DHCP server.

https://en.wikipedia.org/wiki/Preboot_Execution_Environment

The network client boot stack sends a DHCPDISCOVER as a broadcast. Any machine can be listening on UDP 67 (bootps) for this. The real DHCP server responds with the DHCPOFFER containing the IP address the client should use. Around the same time, the PXE server responds with its own DHCPOFFER that does not issue an address, but does contain the values for the requested DHCP options.

The client basically keeps broadcasting DHCPDISCOVER until it gets both, then it does the unicast DHCPREQUEST and wait for unicast DHCPACK with the normal DHCP server.

Now, that said, I've only ever seen this work with commercial PXE servers like Microsoft RIS. To my knowledge, ISC DHCPD is unable to send a DHCPOFFER with options but no address. But my knowledge is at least a decade out of date.

At home I just set the options on the main DHCP server like every other hobbyist does, but this isn't true PXE, this is just plain old DHCP+TFTP remote boot.

Let's say you do have such a server that sends DHCPOFFER with the options and no IP address. If it's on its own machine, then it can listen on port 67, same as the real DHCP server on another machine. But, if it's on the same machine as the DHCP server, it has to listen on port 4011. In this case the client behaves a little differently. For this to work, the DHCP server must send as part of the DHCPOFFER an unsolicited option 60 to indicate that the client should go ahead and accept the IP then send a second unicast DHCPDISCOVER to port 4011 and await a DHCPOFFER from that port. Option 60 is only needed, and can only be used, if the independent PXE server is running on the same host as the DHCP server.

So there's basically 3 scenarios: * Hobbyist: just configure the booting options on the real DHCP server * Real PXE, separate machine: Both real DHCP and PXE listen for broadcast DHCPDISCOVER and respond with complementary DHCPOFFER. Real DHCP server has no knowledge whatsoever about booting. * Real PXE, same machine: Real DHCP server responds with unsolicited option 60 no matter what. This is the extend of its knowledge of booting. Separate PXE server runs on port 4011 instead of 67, and everything is unicast.

There may finally be hobbyist projects that support this model, but when I last did this stuff, there were not. Learning how RIS worked was a revelation for me, and it really made me wonder why the hobbyist community of the time seemed hellbent on not doing PXE correctly, which annoyingly requires control over the options set by the real DHCP server, and often makes it impossible to do fun stuff like use different boot files for different clients.

No law, no crime. [nullum crimen sine lege]

If aliens land in Germany on a field and a peasant shoots them with his shotgun, he would have committed no crime in my opinion. No murder, since Aliens are not humans. It would not be illegal hunting, since aliens are not animals. Illegal discharge of a firearm?

In the US the outcome may be very different.

My most recent interaction with comcast business was earlier this year, end of contract came up.

I finally replaced the SB6183 with a Hitron CODA56 to be ready for midsplit upgrade (greatly improved upload speeds which was showing up in advertising on the same road family business is on). The way their sales works now is terrible, they chain you to a specific rep and that rep has to release you if you want to talk to anyone else. It took me something like 4 reps to finally get one that would sell me what I wanted, a no-term contract at list price without the firewall/spyware crap. No promotion requested. Just the 300mbps tier for that site. Nobody anywhere knew when midsplit upgrades would be complete. Thankfully about 2 months later it was done and that location went from 300/20 to 300/300.

Their business tier was better some years ago, now if I have a tech come out they try to charge me every time because I dared to buy my own modems. Thankfully it’s been pretty reliable, better than the power utility (especially since comcast will literally setup honda inverter gens to keep their nodes up in extended outages).

It's fascinating to me that her new album's name is "Wuthering Heights", the name of Kate Bush's debut and number 1 single from 1978. Kate Bush is well known (in the circles of people who know about this sort of thing) and as fiercely independent and self-controlled artist. I hope Charlii manages her career and fame as well as Kate has over the decades.

Not to mention that the list of acceptable documents has changed multiple times, compliant IDs usually cost extra, issuing clerks often didn't accept digital bills or state documents like voter registration, and some states (e.g. Arizona) only started issuing compliant IDs within the last few years.

It's a rollout practically designed for noncompliance.

Two ordinary paragraphs like one would find in any serious publication, are now enough to make an “impenetrable wall of text”?

You also overlook the fact that many Reddit posts are not links to content. For example, they could be text-post questions posed to a community in order for the OP to receive guidance. This recent culture discouraging substantial discussion about things that are complex and can’t be abbreviated, makes the site less useful that way.

1. get a starlink.

2. else, use their modem. having your own modem excludes it from their service tracking infra and you dont show up when theres problems.

your modem also isnt optimized for their docsis configs and isnt what theyre targeting.

3. the reason for the problems is mainline signal noise causing the modem to drop. cable modem is a conductive signal shared across customers and requires constant maintenance. for example coax lines running to other customers will send noise back upstream, a bad splitter, an improperly terminated end, bent cable, or especially - damaged lines. often hidden in walls and crawlspace.

coax service issues require actual experts to diagnose and fix. all giant isps like xfinity are in the business of getting rid of expensive salaries and equipment. the techs they are sending cannot fix the issue, and if you reject their modem youre deprioritized.

nobody wants to work with cable because its all about signal levels and signal balancing. Fiber is what theyre focusing on as they get paid by the fed to do it.

the regulatory agencies are long past their political debut and are only there to give corpo friends public funds. choose a different service.

Given some of the ways we are still paying for the decisions of the Reagan administration to this day, this is not as reassuring as you make it out to be. If anything it just demonstrates how destructive a president and their administration can be and how the repercussions can be felt for decades.

I have experienced it first hand so many times. You have to understand that PE comes in with an exit plan. They most often do not plan to hold the asset beyond 5, maybe 10 years max. Their goal is to come in, extract as much money as possible in the short term to recoup the expense, and then sell off the remaining assets for whatever they can get for it as a cherry on top.

How do they extract as much profit as possible? Because wouldn't the previous owner have tried to, you know, make as much money as possible? Yes, but PE firms have more capital and scale and will specialize in a certain type or types of business to maximize impact.

Here's how it works:

1. First the PE Firm will focus on a business type - maybe it is auto repair shops, maybe it is pediatric clinics, maybe youth sports facilities and leagues. It doesn't really matter. What matters is that they will buy a lot of them.

2. Now that they own quite a number in a certain geographic area, maybe even most of that type of business they have leverage over customers, employees, and sometimes suppliers. The PE playbook dictates they first cut costs wherever they can. Reduce staff, add surcharges and fees, negotiate better prices with suppliers.

3. The businesses are now operating at a slightly higher margin, which is great, because the initial capital outlay was huge and they had to pay a premium because no one really wants to sell to PE. So over the next 5 years or so they need to make all of that investment back and they usually will. They might lose some employees and some customers, but people hate change and most will stick around even though service is a bit worse. And anyway, who cares, their profit margins are now nice and padded.

4. It has been 5 years and now their businesses are really starting to show signs of cracks. It is getting harder to find competent onsite management who will put up with the terrible work environment. Customers are leaving. Some of those employees are starting their own shops. But who cares, the money has already been made back. Now is the time to sell before the whole thing implodes and if it already has imploded, well, that is less than ideal, but there are still assets to sell. Sell for whatever you can and walk away. The PE firm netted slightly higher than if they were to invest in the stock market. Could they have made even more by just running competent businesses over the long term? Maybe...but that would have required a lot of time and active management and no one wants to do that, so on to the next venture.

I'm inclined to isolate the chat processes only if I keep the bash tool. I'm undecided if I'm keeping it in. Implementing an MCP server in python is dead easy and so is making a bash tool.

Right now I'm more interested in getting ACP working for gemini-cli and claude-code to serve it their models. My first goal is just to make the manually operated tool that just gets out of the way or whatever. Sane permissions out of the box.

If anyone wants to just come along and add an optional feature today, I'm happy to merge under the same license. Otherewise, I will eventually add this feature, I'm just not sure if it will be sooner or later.
