The short answer is nitrate poisoning. It usually happens in infants before it hits adults. The reduction in water volume in the aquifer is reducing the dilution of existing nitrate contamination from agriculture.

From the article:

> Morrow County, Oregon, has recorded nitrate readings as high as 73 parts per million (ppm) in household wells—more than ten times the state’s legal ceiling of 7ppm—following reports that local data centres are intensifying aquifer contamination.

From the CDC:

> The first reported case of fatal acquired methemoglobinemia in an infant due to ingestion of nitrate contaminated well water in the United States occurred in 1945 [Comly 1945]. This condition is also termed “Blue Baby Syndrome”.

Same - I've been using an Intel NUC with Windows 10 for many years. It does everything I want:

- Netflix

- Youtube without ads via Firefox+uBlock Origin

- Ripping DVDs and converting to .mp4

Those Small Form Factor PCs have only gotten cheaper over time - the most powerful PC I've ever owned in 30+ years is a $300 Minisforum (16 Cores, 16GB RAM) that's doing similar duty in the garage.

Location: South Africa Remote: Yes Willing to relocate: No Technologies: Python, Kubernetes, general devops-y stuff. My strength isn't in the particular tech I know, but how quickly I can learn new tech. CV: https://drive.blazelight.dev/s/R5FifJNcS9cwM3x Email: In CV

Currently working as a Senior DevOps Engineer / somewhat of a generalist.

I've been very interested in the LLM space for a long time, and I'm looking to make a move to a position where I work more as a generalist, and work on some cool LLM / agentic projects.

In the LLM space I'm currently working on a general "What's the best chat app you can make if you don't care how much you spend on inference", and I'm hoping to find a company that's doing something vaguely along those lines.

My preference is for small companies (<10 people)

> Why do you need Flatpak for sandboxing?

You don't, but as far as I know, Flatpak or Snap are the only practical, low-effort ways to do it on standard distros. There's nothing stopping flatpak-like security from being combined with traditional package management and shared libraries. Perhaps we will see this in the future, but I don't see much activity in this area at the moment.

Thank you Aaron for the direct response. Glad to see the central interface for administrative use. Haven't had the need to use the calling feature in a while. One of the hurdles with the Rust client on Fdroid was it was too new for the OS on the device it needed to be used on, but on iOS it was a performance improvement.

One of the genius ideas behind Element was the ecosystem of clients services that attach to rooms, and in some cases XMPP does not reach those expectations. I do plan on a redeployment soon after creating a new technical scope for its use.

I like what I can observe of the new admin interface. I hope it can come to include security and configuration check guidances to provide tools for admins of all skillsets to properly configure their servers, and related TURN-or-not and storage.

Matrix is bigtime like XMPP - I don't think it's going anywhere anytime soon. Thankful for all that it has provided to our organizations.

Of course. A skilled driver knows their car very well, and can note by feel that the car is pulling somewhat to one side and correctly identify that this is due to low tire pressure instead of an external effect like road condition or wind, and then decide whether to address it or keep going.

A skilled driver can notice all kinds of other stuff using their senses, too.

For instance: When there's a plume of coolant coming out of the hood in front of them, they can deduce from observation that the engine temperature may be very high. They can also identify low oil pressure by observing the clacks and bangs of an engine that is starved for oil and tearing itself apart, or even by the silence of an engine that has ceased.

Or: Information. A light can illuminate on the dashboard the before these conditions are pronounced enough to feel, and the driver may then elect to use this abundance of information to take action before it snowballs into something that may become expensive or dangerous.

> This means that they should never be used in medicine, for evaluation in school or college, for law enforcement, for tax assessment, or a myriad of other similar cases.

If AI models can deliver measurably better accuracy than doctors, clearer evaluations than professors and fairer prosecutions than courts, then it should be adopted. Waymo has already shown a measurable decrease in loss of life by eliminating humans from driving.

I believe, technically, moderns LLMs are sufficiently advanced to meaningfully disrupt the aforementioned professions as Waymo has done for taxis. Waymo's success relies on 2 non-llm factors that we've yet to see for other professions. First is exhaustive collection and labelling of in-domain high quality data. Second is the destruction of the pro-human regulatory lobby (thanks to work done by Uber in the Zirp era that came before).

To me, an AI winter isn't a concern, because AI is not the bottleneck. It is regulatory opposition and sourcing human experts who will train their own replacements. Both are significantly harder to get around for high-status white collar work. The great-AI-replacement may still fail, but it won't be because of the limitations of LLMs.

> My advice: unwind as much exposure as possible you might have to a forthcoming AI bubble crash.

Hedging when you have much at stake is always a good idea. Bubble or no bubble.

The OBR admits that they published it too early.

I am not an expert but I think that even trading on a leak is not unlawful as long as that leaked information was indeed made public (e.g. someone leaks to the media and the media then publish it), although it may have been unlawful to leak the information. The point is that insider trading is not allowed. It is no insider trading if the information is available to everyone.

I sort-of see where you're coming from, but it also ignores a double standard to me. Don't buy search from a company that uses an api from another company that is (or was? unclear) based in a country that invaded another country and completely upended the world order. For some people that's a line that they don't want to cross and I get it.

However if that's the case how can they continue buying Chinese products when China has done the same thing, but worse, and for longer, to their own population? Because it's less convenient to stop? _That_ to me lands squarely in the "take whatever stand you want" category with the addendum of, "and don't worry if it doesn't make sense."

Is it because it's within their own borders and therefore isn't our problem?

In my opinion, we're possessed by a cultural epidemic of think pieces doing rich and nuanced science history, but wrongly framed in the form of correcting "myths" that, in their substance amount to quibblings over narrative emphasis. It's easy to get taken in by the framing because it truly is enlightening, and the argument goes down so smooth because its embedded in a rich, curious, and fascinating scientific history that otherwise embodies best practices I would happily celebrate.

But the key details about the story of penicillin are that a moldy plate showed bacteria-free clearing, Fleming saw it, isolated the mold, proved its germ-killing filtrate and published the finding, which is the heart of the story and which is not a myth.

I'm sure it's true enough that St Mary's windows were usually kept shut to keep pathogens in and contaminants out, that London's August 1928 cold snap would have slowed staph growth, that Fleming's first notes Or 8 weeks later than the actual event, and that a modern plate seeded with bacteria first will not produce the celebrated halo unless the mold is given a head start. The article makes much of the fact that today’s researchers cannot reproduce the famous halo if they add staph first, yet that difficulty rebuts a sequence Fleming never claimed to have used.

These points are significant, even fascinating, yet the article inflates them into a strobe-lit "MYTH" banner, turning normal human imprecision about times and temperatures into evidence of wholesale fiction, which abuses the ordinary friction of any retrospective account and punishes the story for the very human messiness that makes it instructive.

The window quibble, the incubator gap, and the replication protocol do not touch the central, uncontested fact that chance contamination plus observational curiosity gave medicine its first antibiotic.

> The proposal simply included a provision to turn off hardening, nothing else.

(Guessing "the proposal" refers to the hardening proposal?)

I don't think that is correct since the authors of the hardening proposal agreed that allowing UB for hardened precondition violations was a mistake and that P3878 is a bug fix to their proposal. Presumably the intended way to turn off handling would be to just... not enable the hardened implementation in the first place?
by nathanlied | 2025-12-01 18:17:05+00:00
This has been my experience, effectively.

Sometimes I don't care for things to be done in a very specific way. For those cases, LLMs are acceptable-to-good. Example: I had a networked device that exposes a proprietary protocol on a specific port. I needed a simple UI tool to control it; think toggles/labels/timed switches. With a couple of iterations, the LLM produced something good enough for my purposes, even if it wasn't particularly doted with the best UX practices.

Other times, I very much care for things to be done in a very specific way. Sometimes due to regulatory constraints, others because of visual/code consistency, or some other reasons. In those cases, getting the AI to produce what I need specifically feels like an exercise in herding incredibly stubborn cats. It will get done faster (and better) if I do it myself.

> nothing actually happens besides assigning a new pre-zeroed physical register to the logical register name early on in the pipeline, after which the instruction is retired.

This is slightly inaccurate -- instructions retire in order, so it doesn't necessarily retire immediately after it's decoded and the new zeroed register is assigned. It has to sit in the reorder buffer waiting until all the instructions ahead of it are retired as well.

Thus in workloads where reorder buffer size is a bottleneck, it could contribute to that. However I doubt this describes most workloads.

It reinspired me, the things that i can now pull off with AI would have died a slow death previously. I would have needed to do so much learning, research, debug, i would not have had the patience to complete it. Now i can finally build those things that i never had the time nor patience to do. Currently building my own language, claude code does an excellent job.

This setup was not initially approved, see 1.7 in the document:

> 1.7 Unlike all other IT systems and services, the OBR’s website is locally managed and outside the gov.uk network. This is the result of an exemption granted by the Cabinet Office in 2013. After initially rejecting an exemption request, the Cabinet Office judged that the OBR should be granted an exemption from gov.uk in order to meet the requirements of the Budget Responsibility and National Audit Act. The case for exemption that the OBR made at the time centred on the need for both real and perceived independence from the Treasury in the production and delivery of forecasts and other analysis, in particular in relation to the need to publish information at the right time.

Interesting that in an article entitled "Why I'm betting against AGI hype", the author doesn't actually say what bet he is making - i.e. what specific decisions is he making, based on his prediction that AGI is much less likely to arise from LLMs than the probability the market is implicitly pricing in suggests. What assets is he investing in or shorting? What life decisions is he making differently than he otherwise would?

I say this not because I think his prediction as stated here is necessarily wrong or unreasonable, but because I myself might want to make investment decisions based upon this prediction, and translating a prediction about the future into the correct executions today is not trivial.

Without addressing his argument about AGI-from-LLMs - because I don't have any better information myself than listening to Sutskever on Dwarkesh's podcast - I am somewhat skeptical that the current market price of AI-related assets is actually pricing in a "60-80%" chance of AGI from LLMs specifically, rather than all the useful applications of LLMs that are not AGI. But this isn't a prediction I'm very confident in myself.

OpenAI may be the worst, but I am pretty sure Anthropic is still bleeding money on AI, and I would expect a bunch of smaller dedicated AI firms are too; Google is the main firm with competitive commercial models at the high end across multiple domains that is funding AI efforts largely from its own operations (and even there, AI isn’t self sufficient, its just an internal rather than an external subsidy.)

While working with teams building voice agents in SIMULATE, we kept seeing the same pattern:

PMs and engineers would run large batches of tests, then immediately jump into the workflow graph to replay calls and figure out one thing:

Where exactly did the agent’s path diverge from the intended flow?

The only way to answer that was manual flow tracing — stepping through nodes, comparing expected vs actual paths, and trying to spot the turn where behavior shifted. It was slow but necessary work.

We turned that repeated behavior into a feature called Flow Analysis.

For each test run, Flow Analysis computes and surfaces:

- The exact path the agent took through the workflow - The node where it diverged from the expected path - How the rest of the conversation evolved after that point

This makes debugging more of an engineering task (fix the specific node/logic/prompt) instead of an investigation across the whole graph.

If you’re working with voice agents or complex conversational flows and still manually scanning graphs to debug failures, would be interested in your thoughts on this approach.
