The problem with MCP resources is someone needs to stand up a server. That’s enough overhead and infrastructure that it slows down creating these kinds of resources and linking. Do any of the popular forge sites have like a GitHub pages but it’s MCP kind of capability? I think that would lower the hurdle for standing up such tooling so it would be much more appealing to actually do.

> "react's complexity isn't worth saving 5 lines of code" which people would agree with.

If you look at the code the example shows, the replication is a bunch of HTML and tailwind CSS classes in backbone. So basically if you decide you want to change the input to have a different radius in one place, you need to implicitly know that there's another piece of code patching and replacing that elsewhere, which has duplicated the code.

I'm not one to pray to the alter of DRY like it's the end-all be-all of programming principles, but you take this pattern and repeat it throughout a production codebase and you have a bunch of repetitions that need to happen.

This is the problem with Backbone - it's edits are imperative - meaning, each one is a source of errors. React makes state updates declarative, so you only need write the rules just once. Somebody coming along to edit the code doesn't need to find the implicit relationships in the imperative code that might break or cause inconsistency, because they don't need to exist anymore.

React is safer. It's not even a contest.

The thing is Montessori doesn't mean anything. Any school can call themselves Montessori. So it all depends on actual accreditation. Some accreditations are also not worth the paper they're printed on (like NAMC). AMI and AMS are considered to be the two most serious accreditation

My son's school is AMI accredited and at least there's not much woo-woo here. Children have to be up to date with vaccination (or they're not admitted), only thing slightly woo-woo (from the local point of view) is that the parents who chose this school chose it because they want their kid to have more of a play-based, child directed education and don't want them to have homework and tuition in kindergarten. This is in HK where a lot of children going to public schools will have homework and will get tuition in order to prepare for the primary school entrance exam (and later to the middle school entrance exam).

On the other hand, Waldorf is fully woo-woo. They claim that children should not be taught to read before they get their first adult teeth and have a bunch of very weird racist myth about reincarnation (read up on anthroposophy)

There’s really a risk vs benefit. If you have a brain tumour you need contrast to assess the type of tumour, its growth, if it’s a glioma whether it’s transformed and so on. If someone is being given contrast it is going to change their clinical management.

It seems an odd fixation of just MR contrast when the same could be said of all drugs. Does your doctor/surgeon go into the minutiae of all drugs and possible consequences? By this line of thinking, saline is not without risks, should they go into depth about that?

People already poorly retain information or even comprehend it at appointments or interventions, is there any point adding more burden onto their attendances?

I have a miniPC (Minisforum) with Debian as server.

I use : - Syncthing (https://syncthing.net/) to keep the files synchronized between desktops and laptops computers

- Webdav (https://github.com/hacdias/webdav) to access the files on the server via other applications

- Cryptomator (https://cryptomator.org/) to crypt/decrypt sensible directories (that are synchronized through Syncthing) Cryptomator allow me to access also the directories via webdav

- MaterialFiles on Andrid to access the files on the server

I access my mini server from outside with a Wireguard VPN created on my Fritz!Box router.

Between home and office I created a site-to-site Wireguard VPN between the two Fritz!Box routers.

I think “using technology” is just too broad, and a distinction needs to be made. Screen addiction doesn’t just mean using a screen.

You’re right that it’d be pretty much impossible to refuse to engage with any modern technology these days (unless you lived in an Amish community or something similar); but obviously there’s a huge difference between responsible use of tech where useful or necessary (and for fun, too, in moderation!), and lying in bed mindlessly scrolling through Tiktok and/or watching cable tv for hours every day - which I see a lot more people doing in the past couple years.

But there’s a potential risk of an allergic reaction to any drug you take, any food or drink you consume, even environmental substances - perfumes; hayfever is an allergic reaction to pollens. You don’t know you have one until you have the reaction. I didn’t know I was allergic to penicillins until I needed them for an infection and it turns out I am.

That LLMs have some basic metaknowledge and metacognitive skills that they can use to reduce the hallucination rate.

Which is what humans do too - it's not magic. Humans just get more metacognitive juice for free. Resulting in a hallucination rate significantly lower than that of LLMs, but significantly higher than zero.

Now, having the skills you need to avoid hallucinations is good, even if they're weak and basic skills. But is an LLM willing to actually put them to use?

OpenAI cooked o3 with reckless RL using hallucination-unaware reward calculation - which punished reluctance to answer and rewarded overconfident guesses. And their benchmark suite didn't catch it, because the benchmarks were hallucination-unaware too.

> I assume Apple is probably going to bring this back to pacify

Pegasus and Predator were VERY widely publicised exploits in iOS, I find it shortsighted for Apple not to have control over how these get identified in the first place.

It's also frustrating that the entire "your iPhone is safe and private" assumption is a black box and we only have Fruitcorp's assurances that they're doing the right thing. So imagine, people finding all kinds of bugs on iOS26 ... how is one to believe these bugs and glitches don't extend into security features as well?

This is also what I think is a driving factor behind American politics today:

> Alarming and misleading news may be a particular threat to the elderly, who are twice as likely as under-25s to use news apps or websites.

Millions of people are addicted to watching Fox News paint a picture of the urban US as a war zone that rural and suburban residents should avoid at all costs. That doesn't even include the right wing AI slop on social media sending similar messages. One could argue that this is affecting Trump himself, whereby domestic policy is shaped around what he sees on TV and social media (where was he seeing videos of "bombed out" Portland, anyway?).

A little nostalgic for me, I wrote a bunch of backbone tutorials back in the day.

https://news.ycombinator.com/item?id=3110025 https://web.archive.org/web/20111015073638/https://backbonet...

Other than the lack of imports, 15 years later I don't hate it.

Due to LLM's my thinking about coding has changed quite a bit, I'm far more interested in what is the best way a language can be written such that LLM's can most effectively write it. JSX/declarative is seemingly solid. I think the React community from useEffect onwards is starting to get a bit wishy washy, probably not a great way for LLM's to "think". (something about expressiveness, explicitness and parse-ability)

> The (IBM) mainframe today is a distributed system (many LPARs/VMs and software making use of it)

Not really. While you can partition the machine, you can also have one very large partition and much smaller ones for isolated environments. It also has multiple redundancy paths for pretty much everything, so you can just treat it as a machine where hardware never fails. It’s a lot more flexible than a rack of 2u servers or some blade chassis. It is designed to run at 100% capacity with failover spares built in. This is all transparent to the software. You don’t need to know a CPU core failed or some memory died - that’s all managed by the software. You’ll only noticed a couple transactions failed and were retried. You are right in that mainframe operations are very different from Linux servers, and that a good mainframe operator knows a lot about how to write performant software.

> I can't not wonder if it would be less time & energy consuming if they did it more politely?

This is an interesting question that comes up from time to time and it's actually not as it seems. While it is work and taxing at all, the whole act of explaining is actually not very expensive. In fact, it is simply tapping into the stream of consciousness and piping it into a text input.

What _would_ be expensive actions would be to:

a) _not_ explain, see that something isn't quite right and then try to handle the internal discomfort sparking from that.

b) mask and play a different "more polite" role, which actually just means "accepting the unsolicited emotional offloading and the task of handling those attached to it"

both being "providing a service" to the random person that just approached me, and operating in a style that is unnatural to me. This is counterintuitive for the vast majority of people, because for them it works exactly the other way round.

Doing this emotional labor for free would also be just giving away the thing that makes me money. Specifically, being able to understand technical details and also communicating those to people that won't necessarily do.

Effectively, the free-plan includes technical support but not emotional consulting. This, for some, is hard to understand, for others, it is hard to accept.

And, of course, it always gets worse when social media (like HN) is involved, because these machines erase any context and replace it with violently jamming in defaults + rewarding those that dunk the hardest and make the in-group of the mob feel pleasant feelings.

This is quanta magazine. It is for lay people. The reason people are "nitpicking" the title is that "shape" is not a technical term. The technical term for what was found is "convex polyhedron". I read so much of the article before I was sure that it was talking about convex polyhedra specifically because the title is so ambiguous.

Another person living in Japan. Sounds about right. A unit from a good brand (daikin, mitsubishi) costs ~$800? More or less depending on the room size. We had them installed when we built the house, installation price included. Two are enough to keep our house cool or warm in any season (it's a well insulated house). We have another in the guest room, use it only for when guests stay.

> * Currencies, [...], and exchange rates

Having colleagues for who this topic is "daily business", I really don't know what you intend to teach about this topic to computer science students:

It's either

- basically trivial: you use the provided exchange rate tables which can vary from day to day; you thus just have to thoroughly pay attention concerning the exchange rates of which day you have to use for a given calculation (but this is something the business people will tell you), the rest is like unit conversion, which you learn in school: If the "exchange rate" between yards and inches is 36 in/yd, then 2.5 yd = 2.5 yd * 36 in/yd = 90 in. Similarly, if the f/x rate that is to be used is 1.1612 USD/EUR, then 2.50 EUR = 2.5 EUR * 1.1612 USD/EUR = 2.903 USD (you now just need to ask the business people whether they want to use this raw result, or the result is to be rounded. In the latter case, they will tell you which kind of rounding they want).

- or it is something that you rather need to become an auditor (or a similar qualification) for.

I have to reluctantly agree with you on the merit.

However run0 has a property of being a systemd project, which makes it a no go from the inception. And sudo-rs has a similar property of being a virtue signaling project and not a real one. Hence, sudo stays.

Bayesian thinking isn’t about p-values and doesn’t need to be presented that way.

If you use the centor criteria before resting for strep, is that worse than getting out a piece of paper and researching background population prevalence?

The OP is being dogmatic about doctors needing to know things he does which is obviously silly.

Edit - but yes, I agree that we should think about sensitivity and specificity, I just don’t think you need to be a statistician, just to have a helpful script and resources for patients who wish to know more.

> There was a time when the L7+ principal IC at Amazon/AWS were rockstars in our industry that represented the pinnacle of one’s career.

I dunno, maybe in Silicon Valley or the US in general, but I think most places outside of that took a much more balanced view of those people even back then, they're just humans after all.

Many people experienced working with those "rockstar" engineers outside of Amazon, "rockstars" who still tried to work as if they were still at Amazon, and the obvious effect of that was that it created a lot of needless friction between the people who saw themselves as "I'm the best engineer because I was L7 at AWS" and the rest of the company.

From your jab earlier about my apparent "conservationism" (like that would matter at all), you've lost any good will I may of had with you in this discussion.

Brain / Mind are synonyms for the most. I don't even think you know what you are saying.

It really depends on the engineer. I've seen some engineers in that exact position you describe, their job description says they influence the org broadly so that's what they set out to do. They struggle against a political and technical machine, vying for power, and trying to build a fiefdom.

Other engineers I've seen (a smaller sunset) have that job description more as an observation of their skills and influence. Their mandate isn't to influence, they just do. They are respected for their vast knowledge, historical success, and insight. So they naturally are heeded by most, and consequently they broadly influence the org.

Both cases sound miserable in their own way, but if I had to choose I'd much rather land in the latter. The latter still involves some politics, but at least it sounds like you're not wasting your life playing stupid games.

It's units in 6 different rooms (3 bed, office, living, dining) so 6 sets of units.

After reading some other comments I realize one vital detail is that they were installed in a renovated house that already had suitable holes to the outside and power outlets where the units were going, so the install job was just mounting the units, pulling the tubing and gassing it, no cutting things up or doing electrical work.

The price would at least double if we needed all the holes cut open, and I have no idea what the electrical work would cost.

I didn't know of the existence of SNI and thought that all traffic through TLS was encrypted. SNI sounds like a terrible idea: it should be obvious that leaking domain names will be abused and makes a mockery of any little cute icon in the browser (your government, police, ISP, airline knows what sites you visit). It would have been better to have a secure (ignoring DNS) inconvenient technology stack than a convenient somewhat-secure stack.

After seeing how road design calmed traffic speeds in multiple areas in my city by reducing lanes and using medians that ‘narrow’ the apparent width of the roadway, and in some places just with road paint (it’s weird but it works).

I believe that road design is the only way to control how fast people drive. Speed limits are useless for controlling speed, people drive the speed the road is designed for.

> You then need liquid cooling connection

As far as I can tell, they don’t need external water connections. While everything serious is liquid cooled, they have on-rack radiators. The z17 machines are shipped with the cooling circuit sealed, so it doesn’t need to be filled before use. Power consumption is also relatively low because that’s one demand their clients have that they don’t expand much on top of z16. They are very power-efficient machines.

My only complaint is that there’s no desktop or desk side version. Using z/OS as a daily driver would be an interesting challenge.

This is relevant to HN because it is entirely possible that Flock Safety helped the FBI here.

It's just as likely that mass cellular surveillance tools like IMSI catchers were used, and its a near certainly that social media and tech platforms germane to HN's audience (you (the reader) may work for one!) have also contributed to locating this person.

These tools and the allowances we give LEO and being turned towards good-faith 1st amendment activities like carrying signs and freely assembling.

That article appears to be very confused about how skills work.

It seems to think they are a vendor lockin play by Anthropic, running as an opaque black box.

To rebut their four complaints:

1. "Migrating away from Anthropic in the future wouldn't just mean swapping an API client; it would mean manually reconstructing your entire Skills system elsewhere." - that's just not true. Any LLM tool that can access a filesystem can use your skills, you just need to tell it to do so! The author advocates for creating your own hierarchy of READMEs, but that's identical to how skills work already.

2. "There's no record of the selection process, making the system inherently un-trustworthy." - you can see exactly when a skill was selected by looking in the tool logs for a Read(path/to/SKILL.md) call.

3. "This documentation is no longer readily accessible to humans or other AI agents outside the Claude API." - it's markdown files on disk! Hard to imagine how it could be more accessible to humans and other AI agents.

4. "You cannot optimize the prompt that selects Skills. You are entirely at the mercy of Anthropic's hidden, proprietary logic." - skills are selected by promoting driven by the system prompt. Your CLAUDE.md file is injected into that same system prompt. You can influence that as much as you like.

There's no deep, proprietary magic to skills. I frequently use claude-trace to dig around in Claude Code internals: https://simonwillison.net/2025/Jun/2/claude-trace/ - here's an example from last night: https://simonwillison.net/2025/Oct/24/claude-code-docs-map/

The closing section of that article revels where that author got confused They said: "Theoretically, we're losing potentially "free" server-side skill selection that Anthropic provides."

Skills are selected by Claude Code running on the client. They seem to think the it's a model feature that's proprietary to Anthropic - it's not, it's just another simple prompting hack.

That's why I like skills! They're a pattern that works with any AI agent already. Anthropic merely gave a name to the exact same pattern that this author calls "Agent-Agnostic Documentation" and advocates for instead.

You may want to look at this paper to get a better idea of risk and benefits, e.g. Fig 2 and Fig 3: https://www.ahajournals.org/doi/full/10.1161/CIRCULATIONAHA....

One also needs to understand that myocarditis is not uncommon, and especially common after viral including COVID itself. Also "subclinical" means that this includes mild cases and here the 0.1% also included arrhythmia. Looking at the other paper above, they found 1 (!) person with subclinical myocarditis while screening for it in a population of 4928. Also interesting to put this in perspective: "Underlying disease was present in 109 (2.2%) of the patients, with simple congenital heart disease in 33, mitral valve prolapses in 36, arrhythmia in 36, Kawasaki disease in 11, and previous myocarditis in 2"

Your idea that excess mortality is caused by the vaccine rather than COVID itself seems far fetched to me.
