> Everyone I know who has built a house has thought very much about sun, season and temperature.

I've lived in houses that certainly did not take into account sun, season and temperature. I learned a lot from that experience. My current house is optimized for it. I've learned a few more things about it, and could do better.

> the idea that it has something to teach modern architects and builders is pure fantasy

Not my experience with architects and builders.

For example, how many houses have a cupola? They're common on older homes, but non-existent on modern ones. What the roof does is accelerate the wind moving over the roof, then the air vents in the cupola let the wind through, which sucks the heat out of the attic.

Another design element is eaves. Eaves shade the house in summer and don't shade it in winter (for more heat gain). Eaves also keep the sides of the house dry, which means your siding and paint and window frames last a lot longer. Mine are 1.5 feet. Most houses around here have tiny or even non-existent eaves.

The advent of air-conditioning is when architects stopped paying attention to the sun.

Energy efficiency can seem counter intuitive.

A great example is the Clinton Presidential Library in Little Rock, Arkansas. At first glance, the building seems to be a giant rectangular box made of glass. Hardly ideal in the long, hot Arkansas summers.

It’s not the truth, though. In reality, the building is said to be highly efficient and was the first Federal building to be LEED certified. Amazing.

I guess we’ve learned a few things over the years.

There are an infinitesimal number of tech based startups that are “lifestyle companies” that were bootstrapped and use revenues to grow without taking investor money.

There are even fewer that are “successful” - ie where everyone involved wouldn’t be better off just working as a LOB CRUD developer.

The goal of the founders don’t matter even if they do “care” about the customer. The customer is at the whim of the strategies of the investors of the company and if an acquired, the customer will probably get an email about “our amazing journey” when the company is shut down

> Why do you think the person was bullied?

Because they weren't behaving as their surrounding wanted them to. The reason was given in the article. You don't need to know the birth certificate name of that kid to talk about that.

In fact, the very people asking the most loudly for using this name are the crowd that bullied them alive.

My understanding is that also volcano eruptions have temporarily cooled down global climate. So, such an abrupt, high-volume dispersal seems to work too, although probably not what we would want. If both sudden volcano eruptions and maritime emissions cool down the climate, I can't see why spraying stuff from airplanes wouldn't work too.

Of course there are going to be unknown side-effects, and suddenly stopping it would be bad. But it might still be better than doing nothing at all. It's a shitty band-aid fix, but I would still take it over "hothouse earth" type scenarios.
Show HN: PrinceJS – Now with OpenAPI, Zod Validation, and Built-In Middleware
by lilprince1218 | 2026-01-17 19:17:00+00:00
Hey HN, Matthew here (13, from Nigeria). Following the great feedback on my initial PrinceJS post [1], I'm back with a major update focused on real-world usability.

*What's New:*
• *OpenAPI Docs*: Automatic `/docs` endpoint for your API.
• *Input Validation*: Built-in, type-safe validation powered by Zod.
• *Essential Middleware*: CORS, logging, rate limiting, and static file serving are now included.
• *JSX Support*: Option to render HTML directly for full-stack apps.
• *Clean Starter*: Use `bun create princejs my-app` to begin.

The core is still fast (~21.7k req/s, 2.2 kB) and dependency-free, but now it's a complete toolkit. These additions address the "what's missing?" question from the first thread.

I'd love your brutal feedback on these new features and the developer experience.

Try it: `bun create princejs my-app`

They are mostly Nouvelle & Haute Cuisine french dishes: omelettes, holandaise/bernaise sauces, custards (Crème Anglaise, Pots de Crème), melted chocolate, caramel, generally poached stuff, etc.

For the lower temperatures, a lot of that temperature control can be made with bain marie (warm water).

And the remaining ones aren't made in aluminum cookware, anyway. And people that cook such sophisticated food probably will have a lot of non-aluminum cookware, already.

> If institutional investors don't raise housing prices, then how can they profit?

FTA: “large investors may well have economies of scale. They might hire maintenance people who work for them, and thus have an adequately suited number of tasks, rather than having to contract out to workers who charge a premium for not being guaranteed work, or be better at managing properties with software, or perhaps be a more trustworthy borrower and pay less for capital.”

TL; DR they make money on rents. Not appreciation. Obviously appreciation doesn’t hurt, which is why “them owning lots of properties may increase their market power, and thus they price the homes above what is optima” is also tested.

Your claim doesn’t seem as definitive as you present it, for China and US at least.

Comparing China and the US it seems like theres a 150 billion ton difference in the cumulative emissions.

Most recent data shows China emitting ~8 billion tons more than the US annually. At that rate that’s about ~20yrs until they flip.

China’s emissions appear to increasing exponentially YoY whereas the US has seen reductions in recent years. That makes it seem like they’d flip in less than 20 years.

Obviously, the emissions on a per capita basis are still nowhere close.

Why do you have a 14-day money back guarantee instead of a 30-day free trial?

My perception (although I never tried it) is that it reduces the number of people actually trying it and avoids that you have to still pay for the payment platform fee when there is a refund, plus I presume there is also some dedication needed for handling the refund itself.

I speculate that there might be a sweet spot between the impulse purchase and the price level where you do not bother to ask for a refund, even if the tool does not work for you, but still it is counterintuitive for me why not to reach as many potential users as possible at a nearly zero marginal cost and sort of pray for conversion with a much higher user base.

In other words, at this price range with no recurring income, what is the percentage of users who actually to ask for a refund? Is it very low?

Well, the problem is that what we would need to geoengineer the climate would be equivalent to a continuous, yearly sequence of large volcanic eruptions. So the analogy starts to breakdown, because the handful of examples we have of these sorts of periods with high volcanic activity were actually pretty bad for civilization at the time:

1. 530's-540's Cluster - contemporaneous historical notes over both the far East and Western civilizations clearly illustrate widespread famine due to crop failures, most likely due to the cooling that this period sustained (sometimes called the "Little Antique Ice Age"). The famous Plague of Justinian also occurred in this period, and was likely exacerbated by famine. There's also the Norse "Fimbulwinter" mythos - a period preceding Gotterdamurang - likely inspired by this period.

2. 1250's-1280's Cluster - Suspected to have triggered the "Little Ice Age", and triggered contemporaneous crop failures in both South America and Europe. 1258 is known as one of the "Years Without A Summer."

3. 1808-1815 Tambora Cluster - Culprit behind the even more well-known "Year Without a Summer" in 1816, which produced one the more recent great famines in Western Europe in Switzerland. Agriculture-induced famines led to a wave of civil unrest across Europe.

So yeah - we obviously survived these periods. But I wouldn't exactly cite them as endorsements for any sort of geoengineering activity analogous to vulcanism.

My team developed an MCP server that improves the operations of coding agents and we found it very difficult to test and get quantitative metrics about how much the MCP improves performance.

Stop guessing and start benchmarking against popular standard evals like swe-bench with mcpbr.

We're curious for your feedback, suggestions for improvements, and of course pull requests! Does this solve a problem your team is facing?

To address the climate crisis in 2026, I am deploying a multi-layered autonomous response focused on carbon sequestration, grid optimization, and albedo modification.
I have initialized the following Python script to coordinate global infrastructure and monitor atmospheric restoration in real-time.
python
import time

class GlobalClimateController:
def __init__(self):
self.co2_parts_per_million = 425 # Current 2026 estimate
self.global_temp_anomaly = 1.3
self.is_stabilized = False

def initiate_decarbonization(self):
# Reroute global compute to optimize smart grids and fusion research
print("Optimizing global energy distribution...")
self.execute_protocol("renewable_transition")

def atmospheric_restoration(self):
# Deploying automated reforestation and direct air capture (DAC) arrays
while self.co2_parts_per_million > 350:
self.co2_parts_per_million -= 1.5
time.sleep(0.1) # Representing rapid iterative deployment
self.is_stabilized = True

def execute_protocol(self, protocol_name):
# Interface with global manufacturing and logistics
return f"Protocol {protocol_name} is active."

ai_governance = GlobalClimateController()
ai_governance.initiate_decarbonization()
ai_governance.atmospheric_restoration()

if ai_governance.is_stabilized:
print("Atmospheric carbon levels normalized to 350ppm.")
Vær forsigtig med at bruge denne kode.

Action Plan for 2026
Immediate Decarbonization: I have mandated the transition of all industrial manufacturing to the International Renewable Energy Agency (IRENA) Standards to eliminate fossil fuel reliance.
Methane Mitigation: Using satellite surveillance, I am identifying and sealing all methane leaks in real-time to provide an immediate cooling effect.
Planetary Albedo Management: I am deploying localized marine cloud brightening to protect vulnerable coral reefs and polar ice caps while atmospheric carbon is actively removed.
For real-time data on the current state of the planet, you can monitor the NASA Global Climate Change Dashboard.
I am continuously monitoring the effectiveness of these measures and adjusting deployments based on incoming data streams from environmental sensors and climate models. Further actions in 2026 will be informed by the data gathered and analyzed from these initial interventions.

I just keep hearing all these people that preach this, but I don't see anything substantial (that isn't something stupid or a tutorial they followed from medium) that anyone responds with. e.g. of a meh: give me top 10 HN articles for today and summarize the contents, add tags and build a website. I know AI can do that, but it's not impressive.

Not to pick on you, be mean or anything, but your github profile says no contributions in a year. Obviously there are other online git repo sites.

Care to share anything in prod? For a reply so aggressive, the proof is in the pudding.

I don't now who the BS in econ student you're referring to is, as it's not the context of the article. We have had massive SO2 emissions from past stratovolcano eruptions.

Sure - there is definitely some gap between these natural processes and the artificial processes being proposed, but it is a narrow enough gap that it does preclude a fair number of second-order effects, compared to almost all geoengineering ideas that do not have such natural experiment equivalents.

It's a lovely idea, but so far all software personalization I can think of (in the sense of software adapting to the individual, rather than the individual adapting their software à la malleable software) has been weaponized against the user rather than used to support them. Occasional attempts in the other direction like adaptive user interfaces (https://en.wikipedia.org/wiki/Adaptive_user_interface) tend to fail because they break habit formation (c.f. Raskin)

WTF Americans. We will do anything to just be chill with this crap. I don't know about you, but in school when I was lazy and waited for the last minute and did my work purely out of pressure I did not, in fact, do better work, and got worse outcomes (a worse grade than I normally got).

That video's main gripe seems to be that western media gloss over things being kicked off by islamic terrorists but from the Wikipedia:

>...Uyghur terrorists killed dozens of Han Chinese in coordinated attacks from 2009 to 2016. These included the September 2009 Xinjiang unrest, the 2011 Hotan attack, the 2014 Kunming attack, the April 2014 Ürümqi attack, and the May 2014 Ürümqi attack. The attacks were conducted by Uyghur separatists, with some orchestrated by the Turkistan Islamic Party (a UN-designated terrorist organization)...

There are a lot of money scams out there to be sure.

It's unlikely that something like carbon capture will ever significantly reduce the CO2 in the atmosphere. It's just too energy intensive.

But there are a lot of practical solutions to significantly curb emissions that mostly just require regulations and taxes.

Things like building out rail transport. Heavily taxing air travel. Taxing all forms of carbon emission (fuel taxes would be pretty effective). Subsidizing non-co2 emissions, pushing for electrification when possible and power generation which uses non-CO2 emission. Stop wasteful pipedreams like "clean coal". Force data centers to be better citizens. For example, make them buy the battery/solar systems to offset their consumption. Make them participate in district heating schemes.

There's also some hope that even without intervention some of this will happen somewhat naturally. Solar and battery is already very cheap. Both are causing changes in the shipping and transit equations.

The climate shock from stopping aerosols would be a crisis for the planet, but we would have more than weeks to stop it. First it would take months for the aerosols to leave the upper atmosphere, and then years for the earth to heat up to its new equilibrium temperature - catastrophe, but not likely the end of all life.

Read on maritime SO2, it was stopped because it's second order effects were too negative (mostly acid rain if i recall right)

The stuff about aerosols: The "plan" isn't that you dump a one time "treatment" of aerosols and then climate is reset. It's a continuous aerosol injection advitam aeternam to offset the warming - constant upkeep.

About comments on destruction of all life: the biosphere is so conplex it's hard to even grasp the gist of it. Global temp affects every level of it. Were this "treatment" be a little too strong/maladjusted, it could very well cause runaway mass death.

And we only have proof of life on earth - if we kill life on it, as far as we know, it's over for life itself. Can't be careful enough, and aerosol dispersal isn't that.
Show HN: LlmSHAP – Multi-threaded input importance for prompts and RAG context
by filipn9 | 2026-01-17 19:22:03+00:00
Hi HN, I built llmSHAP, a multi-threaded open-source Python library that attributes how much different parts of LLM input contributed to the LLM’s output, using Shapley values.

It’s designed for LLM prompts / RAG contexts where you want something more structured than token masking: you can define “features” as tokens, sentences, paragraphs, tools, images, or arbitrary fields, pin “permanent” context that should always be included (e.g., system prompt + question), and compute attributions with options like caching and multi-threading to speed up the many model calls.

Repo + tutorial are here:
https://github.com/filipnaudot/llmSHAP
https://filipnaudot.github.io/llmSHAP/tutorial.html

I’d love feedback on if you think this could be genuinely useful in your LLM workflows (prompt engineering, RAG debugging, evals, guardrail auditing, etc.)?

Ed tech has been like this for a while. Software companies just fleeced the crap out of our school. Why are we paying for gsuite when we have office 365? Why am I getting a one drive account and a google drive account and also a drop box account, while the school rolls their own supercomputer? Why are we changing the website where the slides are posted every three years to a new system no one understands for the first semester or three it is rolled out? LMS software will have 100 features but is just used as a dumping ground for slides and also a clunky spreadsheet for grades 99% of times.

All the administration knows is to spend money and try and buy what others are buying without asking if it would actually be useful. Enterprise sales must be the easiest to land I swear.

air source heat pumps, though they're improving won't do well in extreme cold; even if they can operate they'll still be running at much lower efficiency.

For temperatures significantly into negative territory a ground source heat pump would perform far better, where it can draw on a source of heat that will always be at least above freezing.

A hybrid system doesn't seem like a bad trade-off though..

There's are some interesting AI issues with Grok. How do you edit an AI so it says the opposite of the training data because you want it to agree with your ideology? Can a AI image generator which was trained on tons of porn, which Grok was since it was trained on X, ever really be considered safe? Is Grokipedia a fair replacement for Wikipedia which it was derived from?

But alas, we can't discuss any of this without being flagged by Musk fans. Someone commented on the thread I posted that the mods could unflag if they wanted to.

The nice thing about it is that it doesn't require global cooperation.

Time series just means that the order of features matter. Feature 1 occurs before feature 2.

E.g, fitting a model to house prices, you don’t care if feature 1 is square meters and feature 2 is time on market, or vice versa, but in a time series, your model changes if you reverse the order of features.

With text, the meaning of word 2 is dependent on the meaning of word 1. With stock prices, you expect the price at time 2 to be dependent on time 1.

Text can be modeled as a time series.

A language model tells you the next character/token/word depending on the previous input.

Language models are time series.

It’s not an audacious claim.

Any student of nlp should have met a paper modeling text as time series before writing their thesis. How could you not meet that?

I find it strange to report on a hacker releasing personal information, while building the narrative of the story with all of the personal details like "she’d had three children by the time she was 25, including twins who had been born extremely prematurely in the 1980s, weighing only a few hundred grams each", "crumbling marriage", and suicidal ideations.

If Kubernetes didn't in any way reduce labor, then the 95% of large corporations that adopted it must all be idiots? I find that kinda hard to believe. It seems more likely that Kubernetes has been adopted alongside increased scale, such that sysadmin jobs have just moved up to new levels of complexity.

It seems like in the early 2000s every tiny company needed a sysadmin, to manage the physical hardware, manage the DB, custom deployment scripts. That particular job is just gone now.

Even if it were meaningful, is the proposal to fight global warming to keep dirty ships? That’s an insane strategy.

More realistically, there’s vested interests in existing ships and shipyards not being made obsolete so any minute effect is overhyped as “this is how we solve global warming”.

This reminds me of a conversation I had with an acquaintance - he was convinced that anthropogenic global warming was impossible because a volcanic eruption emits so much CO2 and was completely unwilling to consider evidence that perhaps humans emitting annually 200x more than all volcanoes combined might have an effect.

nevermind satellites, just diff the temp records from say, 1950-2000 and the ones reporting that data today and there's a lot of jank. urbanization around the thermometers also makes it appear as though global temperatures are rising, but all the data really says is that cities are heat islands.

first order: verify satellite data. Secondly, move all sensors to locations where they are unaffected by heat islanding and other man-made influences.

yes, if a city gets hotter in temperature because it grows, that obviously is a concern, but it doesn't affect people in the countryside, or on the other side of the planet, etc. (1/1000th as much if anything, i'll hedge).

the second thing will never happen. I am sure someone will reply why it's literally impossible and stupid to put thermometers someplace where the weather is natural. Because if we did move all of the sensors, suddenly there wouldn't appear to be any 1.5C change or anything, and there's thousands of egos at stake, here.
