Now add that nuclear power has famously had a negative learning curve. It doesn’t even take the latest boondoggles into account.

https://www.sciencedirect.com/science/article/abs/pii/S03014...

At the same time storage is absolutely plummeting in price with the latest auctions in China landing on $63/kWh serviced for 20 years.

Then we have comprehensive grid modeling:

See the recent study on Denmark which found that nuclear power needs to come down 85% in cost to be competitive with renewables when looking into total system costs for a fully decarbonized grid, due to both options requiring flexibility to meet the grid load.

> Focusing on the case of Denmark, this article investigates a future fully sector-coupled energy system in a carbon-neutral society and compares the operation and costs of renewables and nuclear-based energy systems.

> The study finds that investments in flexibility in the electricity supply are needed in both systems due to the constant production pattern of nuclear and the variability of renewable energy sources.

> However, the scenario with high nuclear implementation is 1.2 billion EUR more expensive annually compared to a scenario only based on renewables, with all systems completely balancing supply and demand across all energy sectors in every hour.

> For nuclear power to be cost competitive with renewables an investment cost of 1.55 MEUR/MW must be achieved, which is substantially below any cost projection for nuclear power.

Or the same for Australia if you went a more sunny locale finding that renewables ends up with a grid costing less than half of "best case nth of a kind nuclear power":

Show HN: Lightski – Cursor for Technical Design Docs, Peer Reviews, and PRDs
Hey everyone! My name’s Hansen and I’m the founder of Lightski. We're building an AI-powered text-editor to help engineers write technical design docs, RFCs, peer reviews, onboarding docs, PRDs (basically anything that’s not code). You can sign up and try it at https://www.lightski.com/

Previously as a tech lead and engineering manager, I wrote TDDs and RFCs almost once a week. I spent more time writing in our knowledgebase (Slab/Notion) than writing code! AI has revolutionized how we write code (Cursor, Windsurf) and prose (Type.ai, Lex, Jenni, Gemini), but there hasn’t been any tool tailored to the types of documents an engineer needs to write, until now.

Lightski is a collaborative Markdown text-editor that indexes and references your company’s Github repository. This allows Lightski to find relevant files and schemas, and format them appropriately for a document. For example, you can:

* Ask Lightski to automatically convert a DB schema into a more readable table: https://www.lightski.com/videos/2025-02-13-schema-transforma...

* Create a first draft with citations to code: https://www.lightski.com/videos/2025-02-13-new-document-1.mp...

* Explain complex code logic in pseudocode

* Fetch recent commits to draft a self or peer review, etc!

Long-term, we’re aiming to build an intelligent knowledgebase for technical information: one connected to your codebase, documentation, and ticketing system, in order to speed up how teams collaborate. We believe that written communication will never go away and aim to build the fastest possible way for engineers to write down what’s in their brain to help with collaboration.

I’ll be in the comments, or feel free to email me at founders@lightski.com!
Showing that you're willing to pay extra for green products (or products that respect animal welfare, etc) creates a competitive environment in which companies can compete on who provides the most green per dollar. Even if those marked up products are all just greenwashed today, it still creates a market opportunity for new companies to come in and outcompete today's greenwashers with products that deliver better green per dollar in the future.
Love it!

Last summer I put together a flag quizzing game with my niece, who's a geography nerd: https://flagsaroundthe.world/

I think minimally contrastive examples work well for learning, i.e. you want to first learn to distinguish between broadly different categories, and focus on more and more similar examples over time. This little app doesn't have scheduling at all, it just samples examples based on previous responses, so sampling examples you got right exponentially less often as you keep answering correctly. I think sampling has some interesting advantages to SRS scheduling actually. Add new "items" becomes a straight sampling problem, where you can set a constant probability for each item that hasn't been seen yet.

They do. And Chinese companies deliver the $25,000 EV they promised without bitching to politicians about how hard manufacturing is.

That is how competition works in the free market, yes.
HN has never been unbiased. It is funded by a tech VC company and targeted at tech entrepreneurs. It has always promoted crypto and AI scams to an eager audience and pumped up one useless company that added nothing of value to the world after another.

Despite that there has been a general interest in "tech" and clever things and intelligent discussion here that appeals to a reasonably broad community so the place works.

The massive wealth concentration and power amongst a very few, the Paypal mafia, Andreeson etc has led them down a path that puts them at odds with the rest of us. Regardless of our diverse politics regular engineers aren't going to have more individual or economic freedom in a world controlled by a small group of oligarchs. They care about us about as much as we care about ants.

I wouldn't say the tech world has blessed the regime but many unquestionably revere the financiers of the tech world. We (techies) for all our talk of individual liberties have a problem with cult like thinking. Most of us aren't stupid and we can justify our positions, any position. And while some flagging of discussions might be sock puppets or bots, the truth is a lot of people still thoroughly believe the hype.

This is pretty much the exact opposite of how I see the world with regards to data modeling. I suppose I'm a sum type radicalist. There are few non-trivial things in the world that I would model without heavy use of sum types.
It is hard to put a pin on this one because there are so many thing wrong with this definition. There are agent frameworks that are not rebranded workflow tools too. I don't think this article helps explain anything except putting the intended audience in the same box of mind we were stuck since the invention of programming - i.e. it does not help.

Forget about boxes and deterministic control and start thinking of error tolerance and recovery. That is what agents are all about.
He claimed no one else understood his theory (stating that only he alone was smart enough), so it wasn't really possible to disprove it.

They've sold over 20 million headsets, they completely dominate the market. Even most enthusaists buy the Quest 3.

I'm not a big fan of Meta as a company but this article is such obvious horseshit to anyone even casually acquainted with the VR industry. Junk journalism.

Stan Ulam has a great book discussing his worry about the change in research environments pre-wwII vs post-WWII. Before the war, they’d sit in cafes and draw in tables and just sit and think sometimes as a group. After they would meet in offices with blackboards and no life in the room or fun with direct funding telling them exactly what to study. I think his concern will be shown to be sound.

I wonder if LLMs can help bring that kind of exploratory culture back. Because this is not an exploratory culture.

> We were talking about a potential new non profit platform not facebook.

We were talking about the impact that platforms with real name policies have on society simply by existing and being widely used. Particularly relevant considering that the first comment in the thread was about just such a platform being officially provided by the government and tying accounts to a government issued ID. The second comment in the chain, which you responded to, explicitly referenced Facebook.

Your arguments don't hold any water and you're having difficulty accepting that fact.
Well it wasn’t affordable housing in that sense, but it was affordable in the more general sense: my rent in Tokyo was around 15% the median Tokyo salary. Good luck finding that in California.
Twitter is a cesspool and the rise of Bluesky, Threads, and Mastodon have managed to eat away at a lot of the left and centrist leaning Twitter user base. You could argue that the only value it has left is the influence it can enact during this right wing wave. What will happen afterwards? Probably that recent rise in valuation to bring it back to Musk's purchase price will reverse and then it will be tossed in the dumpster.

Pretty sure the Chinese version of a Tesla isn't much worse than the actual thing. The only car I've owned that I liked worse cost $150 dollars in 1991. I don't like Elon Musk, but I hate being ripped off worse.
At first I thought, great, we can add it now to our platform. Now that I have seen the price, I am hesitant enabling the model for the majority of users (except rich enterprises) as they will most certainly shoot themselves in the foot.
You say it hurts readability but most of the time I want the unhappy paths to be visible.

Coding software that works when conditions are met is easy. Coding software that works when things break is hard. So I want error handling to stand out because it forces errors to be handled visibly and properly.

All too often I see Python programs drop to a stack trace under normal execution or JavaScript return cryptic errors that don’t mean much to anyone bar the core maintainer. But I seldom see 3rd party Go software bomb out in quite the same way. And I think that’s in large part because Go doesn’t try to hide errors away as an inconvenience that we shouldn’t be looking at.

So I’ll agree Gos approach is ugly. But sometimes good software does just look ugly. And the way I see it, it’s the quality of the compiled software that matters more than the beauty of the combination of characters that built it.
> It seems that they're willing to let vacancies happen instead of lower rent rates

Anecdotally (as well), no small-time landlord I know wants vacancies over accepting lower rents. Almost all of them, however, would prefer a vacancy over getting a problem tenant who will be late in rent, not pay at all, or trash the place. This effect is especially strong in places with strong tenant protection laws.

Professional management companies of big apartments might be different.
This is the first time I've heard anyone argue that a food product must be good for you because Americans are consuming a large amount of it. How on earth could you come to that conclusion given how unhealthy our population is?
Any elections in the People's Republic of China occur under a one-party authoritarian political system controlled by the Chinese Communist Party (CCP).

It's not the same, and as a consequence of being one-party; means (like the parent suggests) they can be more long term focused, which seems to be working.
I agree, Apple is moving very slow relative to others and I feel as if the way for them to get ahead is to just be more open for once.
I regret that you think that, but I’m not explaining to you why you’re wrong, it’s as pointless as you trying to convince me that I’m demonizing anyone with that comment.
There are definitely laws and lender requirements that should make appraiser selection somewhat random and their findings somewhat neutral, but based on my house buying experience I don’t believe for a second that they’re effective. We made a bunch of offers and somehow the appraisal was always right at the offer price or ~5-7k above. I’m convinced that the appraisers somehow have knowledge they shouldn’t and covert/indirect mechanisms exist to motivate them to play ball to make deals go through.

Besides small sample size giving me a skewed sample, the other explanation I can think of for this is that appraisal is a fairly exact science and realtors have mastered pricing based on it. Considering the volatility of my market, lack of comparable sales, and the IQ of the realtors I’ve met that seems laughable.
The algorithm must be surfacing only the pro elon content. I mostly see the pro stuff in his responses, anything anti is buried.
Doesn't that seem like a given? That people without the incomes to afford housing in a given locality don't own housing there?
Disagree here - I recently took delivery of a BYD Shark 6 and was especially impressed with the build quality and interior quality. I'd say on par with the BMW X5 we had, and slightly better than the Polestar 2 that we have.

The software on the other hand... I would love per-key profiles (like the polestar) and buttons doing the thing they're labeled for when using CarPlay - but I _hope_ these things can be updated OTA. The UI and responsiveness is really quick however, especially compared to the P2 which feels woefully underpowered with constant UI lags.

Terrible software seems to be par for the course in cars.
That's what it does in Go too. This is totally defer in the Go sense (except they fixed the scoping issue).

It's hard to do worse. My Uber rides in a Model Y and X have not given me much confidence in Tesla's design chops. Which is a shame, since Starlink works so well and SpaceX seems to manage fine despite their struggles. I'd love to buy an American-made electric vehicle someday, but I'm fine buying ICE until the market gives me alternatives to Tesla.

I don't even really hate Musk all that much, I just find it hilarious how people refuse to admit that he lied about FSD and continues to fleece American taxpayers for Tesla's welfare. A fair economy would just let Tesla die already and stop dragging it's corpse up and down Wall Street.
I agree with this, what you put into the prompt will reflect in what you get out, so just be more detailed.

> I'm not sure how costs of sewage etc. change with increased population density. Pipes have to get wider per person, but low-density also means they're longer.

Probably accurate to say that in general, the great majority of the cost of infrastructure is in labor, not materials. It doesn't matter if pipes are a little wider or longer; the labor of digging up dirt and installing pipes, and doing that over time as things need maintenance, would far exceed.
Dark Energy experiment challenges Einstein's theory of Universe
I hope that if we switch away from FreeType, we'll still have a way to use TTF hinting instructions fully.

Windows/macOS don't seem to have a way to enable proper hinting anymore [0], and even FreeType (since 2.7 [1]) defaults to improper hinting (they call it "subpixel hinting", which doesn't make sense to me in theory, and practically still seems blurry, as if it's unhinted).

In case anyone's wondering what properly hinted text looks like, here's a screenshot [2]. This currently relies on setting the environment variable `FREETYPE_PROPERTIES=truetype:interpreter-version=35`, possibly some other configuration through fontconfig, and using a font with good hinting instructions (eg, DejaVu Sans and DejaVu Sans Mono in the screenshot).

My suspicion is that Windows moved away from font hinting after XP because it's very hard to create fonts with good sets of hinting instructions (aiui, OTF effectively only allows something like "autohinting"), so in the modern world of designer fonts it's easier to just have everyone look at blurry text. Some other minor reasons would be that UI scaling in Windows sometimes (or always?) introduces blurring anyway, and viewing raster images on screens of varying resolutions also introduces scaling blur.

[0] Windows still has a way to enable it, but it disables antialiasing at the same time. This is using an option called "Smooth edges of screen fonts" in "Performance Options"). This basically makes it look like XP, which imo is an improvement, but not as good as FreeType which can do hinting and antialiasing at the same time.

>Giving money to an enemy of the people should have consequences, even after the fact. That's how we prevent it from happening in the future.

I'll remember this comment when conservatives are the ones destroying something because the owner/CEO/etc. are Marxist child groomers or whatever. They'll be justified because giving money to an enemy of the people should have consequences, even after the fact. That's how we prevent it from happening in the future.
It's very unlikely that's true. Why are there basically no such startups that are Android-only?
Unfortunately, in the system most of us work in today, I think overconfidence is an intelligent behavior.
This is complete madness.

So, you define who is an “enemy of the people”?

You’re more dangerous than the “problem” itself.

Great article, but I didn't see anything about the costs.

I'm particularly interested in this aspect because we're considering fine-tuning Gemma 3, but our budget is tight. We're looking into (real-world) cost estimates for this approach.
Insomniac faced job cuts just 4 months after releasing Spider-Man 2, a game that sold 11 million units and had a score of 97% on Opencritic at release. Epic Games also laid off staff last year. They made a game you may have heard of called 'Fortnite'. It's been rather successful.

But then so has most of the industry, which has experienced growth year-on-year.

A profit does not prevent layoffs and no individual can 10X themselves to safety. There is a huge power and incentive disparity between the people with the power to initiate layoffs and the people who get laid off. There's a way to shrink the gap, but it means accepting you have more in common with your colleagues than your shareholders, then communicating it collectively.
I'm just saying that, at least to my sensibilities, the viewpoint that leads one to be concerned about maximizing the efficiency of 150 bucks over the next 4-5 months seems incompatible with the viewpoint that it would be reasonable to spend $150 on this watch at all.

But I recognize that everyone's a snowflake, so you do you.
Well said. I should stop using social media, the level of discourse is low and anti-intellectualism is rampant. I do think the world would benefit from more amateur researchers.
It has a 2023 knowledge cut-off, and 200k context window... ? That's pretty underwhelming.
Well, in my particular case, I use an M1 Max MBP with a 2K monitor that I already had when I bought the MacBook.

The problem with 27" 4K monitors is that you can't have integer scaling on them. If you set the scaling factor to 1x, everything will be too small, if you set it to 2x, everything will be huge, and macOS can't properly do fractional scaling because what it actually does is render everything into a 2x framebuffer and downscale that for output.

And besides, only supporting HiDPI displays doesn't mean one can stop striving for pixel perfection. I hate SF Symbols icons because they're sizeless. They're an abhorrent blurry mess on my monitor but they're also not all that sharp on the MacBook screen. If you notice it once, it'll haunt you forever. Sorry. They do look fine-ish on iPhones though because those use OLED displays that lack the notion of a pixel grid anyway.
Some of them are renting them out, yes. But I still think it should push the price up because people with zero houses will be competing with people with > 1 house, which increases demand.
