Just to consider this on a small scale where, it would actually need to be implemented, one neighborhood at a time, I live in a medium-sized town where the school district has chosen to reject free land that developers attempted to donate to the district for the construction of schools, in favor of just assigning the families who move into these new-build homes to the schools in the other part of town where schools have ample capacity due to the large 4+ bedroom single-family homes mostly being owned and occupied by empty-nest Boomers.

We live somewhere in between the "new builds" part of town and the area that has a bunch of schools, so the walk from our neighborhood to our assigned (and closest) middle school is only 2.5 miles, a 55 minute walk with 155 ft elevation change. This walk takes you across a road with a 60MPH speed limit, basically an expressway. The elementary school is a bit closer, only a 40 minutes, 2 mile walk, but same expressway.

Oh, and they don't even offer a school bus of any kind. I suppose the gen-x parents killed that idea off 25 years ago because they were so worried their kids would be out of direct supervision even walking to a bus stop, so each child is chaufferred door to door, rain or shine, until 16 when they receive their own cars.

I agree with you that all this is absurd. Kids are capable of walking to school and shouldn't have to leave a medium-sized neighborhood to do so. But significant demolition of neighborhoods and construction of schools, local grocery markets, etc. is the only prescription for our ills that would provide anything resembling an alternative to cars for the residents of the tract homes that make up a significant part of our car-dependent suburbs.

This is why I think whoever upthread is arguing that people aren't exactly being reasonable expecting the America we inherited from the 20th century to stop stalling and transform itself into 1,000 Amsterdams. Even though the places that share that awesome non-car infra are highly sought-after.

I’ve also seen a few of those where it gets the answer right but uses reasoning based on confabulated details that weren’t actually in the photo (e.g. saying that a clue is that traffic drives on the left, but there is no traffic in the photo). It seems to me that it just generated a bunch of hopefully relevant tokens as a way to autocomplete the “This photo was taken in Bern” tokens.

I think the more innocuous explanation for both of these is what Anthropic discussed last week or so about LLMs not properly explaining themselves: reasoning models create text that looks like reasoning, which helps solve problems, but isn’t always a faithful description of how the model actually got to the answer.

Exactly. At some point a lot of people are going to discover that they are the bag-holders.

It's unfortunate, and at an individual level you can't blame people that felt compelled to purchase a home (only one!). However, if people are honest with themselves, they would admit that the only reason they were willing to pay such a high price is because they expected the price to increase. In other words they were speculating. After a certain point, nobody was buying for the actual ROI (i.e. income potential or substituted rental value). Not only was this mistake made, but it was made using massive leverage in most cases.

TLDR; Nobody was willing to admit that they were making a risky investment. A risk that it may turn out that they couldn't afford to make.

Obviously there are pluses and minuses for both but the pluses outway the cons otherwise companies wouldn't have survived after years of it. No this is just popular because the elite noticed workers were feeling happier and more empowered and they feel threatened by that. So along come Trump with an escape hatch, and they make up bullshit about DEI and WFH not working even though it worked for years and stock market was way up. Nope this is all about the old boys network trying to keep the peasants in place and save a few bucks this quarter.

/active is a toxic version of HN. It's old but has become popular recently - https://hn.algolia.com/?query=%22news.ycombinator.com%2Factive%22&sort=byDate&type=comment

HN is a house built out of Chesterton's Fence, this is an old algorithm newly multiplying in the wild.

This is not to the mods, this is for users to think about. Even if you avoid the active list, when a front page item goes there it will also go toxic. /active doesn't contain users like shadowban.

> AMP is a subset of HTML plus some javascript libraries. The subset thing means you had a limited API. That was the point though, the limited API was restricted to the set of things that could be forced to be performant. That is "control" in some sense, but it wasn't control in the common sense of limiting content or ad networks or whatnot. Virtually every ad network had a library for running on AMP.

Javascript libraries that MUST be loaded from one specific Google CDN.

If I load the exact same libraries from my own domain, suddenly it's not "valid" AMP anymore.

It's not a standard if it only works with one specific implementation.

TECO was a character-oriented editor. Also, it was widely available on RSTS, RSX, RT-11, ... and other DEC systems in the mid-70s. There's a character cursor. So if you opened a file with:

The quick brown fox jumped over the lazy.

The cursor would start before the T. 4C would position the cursor before the q. The 6D would delete quick . Then <esc><esc> would execute the command buffer.

These fingers of mine learned TECO before they learned vi and then found vi easier to learn as a result. Besides the basic editing syntax, it was a programmable editor, hence the TECO emacs macros.

Funny thing is that as fondly as I remember TECO, I've tried emacs a few times and have always worked my way back to vi/vim. I particularly like neovim now. I like using ex/command mode for doing bulk editing. Of course you can do the same thing in emacs but I've gotten used to it in vi. I remember programming TECO but I don't remember ever doing programmed editing.

Pretty classic arguing a point no one makes.

Sea and air electric travel is and has always been the final frontier of transport electrification, and no one expects it to come easily. As tech currently exists I don't see a path for battery technology to supercede existing fossil-fueld solutions. That could change though if newer, more advanced battery tech comes out but for now it's just not really commercially feasible.

I wouldn't trust a thing this guy says about it though, because he appears to know essentially nothing about the topic he is talking about. I'm glad he includes that tweet at the start because it demonstrates his own lack of knowledge instantly. It's hilarious that he actually is off by a factor of ten :D

Pilot here, I don’t think this is right.

Aircraft typically operate at 80-100% power output. It’s not the average 20% power output of your car.

Weight is pretty much everything, the savings from regenerative braking in an aircraft are almost 0% but the cost of enabling it is some tons.

This tech makes loads of sense in a car but I’ve never flown an aeroplane in stop-start traffic because that’s not how the sky works.

One vague possibility: hallucinations are mitigated by looking at uncertainty in token prediction, the idea being that it’s a proxy for factual uncertainty, and the system is more likely to confabulate a court case or whatever if it only has a fuzzy idea of what comes next. But this won’t work for reasoning models which solve math problems: the next token for “x=“ is highly uncertain until you’ve done the computation!

18 U.S. Code § 242, “Whoever, under color of any law, statute, ordinance, regulation, or custom, willfully subjects any person in any State, Territory, Commonwealth, Possession, or District to the deprivation of any rights, privileges, or immunities secured or protected by the Constitution or laws of the United States…”.

The judge erred in granting the warrant, the police violated the above statute. Them being unaware would be an affirmative defense, that does require admission of the above crime.

> Average EV range has increased 2.7 fold

Don't dodge the question like that. I said efficiency hasn't improved. You basically said, the car got 2.7 fold bigger.

Consider that Gen1 Nissan Leaf already had 24kWh battery and 200km(125mi) rated range. Today's EV with 100kWh battery packs has at most 500mi - literally zero improvement.

CHAdeMO supported up to 62.5kW since 2009 or so. It can do 400kW now, that's still not even 10x improvement.

Battery cost did marginally decrease. Currency inflated a bit over time. Battery capacity increased accordingly from those. And you spun that into a "350 fold increase".

Shame on you.

The productivity comes from not having to think about your editing while simultaneously realizing that you can do some complex editing really easily. I use Emacs and Vim both (I prefer Emacs) and It's quite nice when you can streamline some quick code edits.

My latest experience with Vim was helping a friend fixing some import with a React Native project. A quick grep on one terminal (I could have used quickfix) and using the vim fzf plugin to quickly locate the file. VS Code could have done this but the context switching and UI clutter is not great there.

As for emacs, the main advantages lies in the fact that so many great tools already exist there. Things like Occur, Shell Mode and Compilation Mode (relying on Comint, a more general feature for anything REPL), Project, Eglot, and Magit.

> The major categories of visible life on Earth have been pretty much settled for centuries. But it wasn’t until the 1980s that scientists found “intraterrestrials” — microscopic organisms living in what the biogeochemist David Valentine calls a “microbial purgatory deep below the Earth’s surface."

Does anyone know the paper(s) from the 1980s where the discovery was published?

It's not a "current state of affairs" the industry has been like this for the last 30 years.

There is a difference between a "private" company and a "startup" the problem with startups is they mainly hire younger workers that are willing to take two trigger private stock options that will almost never trigger. Only the equity investors get single trigger options for when the company gets bought by a big player based only on the valuation (that's the end goal of startups 80% of the time).

While a truly private company (think Harbor Freight, etc) will be focused on building the business not the valuation and if they do offer private stock as a cash build it's very limited but single triggered. It's almost always bought back in a buy back so no loss of money typically.

I tend to work in the large corporation side which is a different beast altogether. I did just get bit by a tiny little startup but I knew that was coming from the start. It was an easy 2 year pay-day.

I started with TECO (Text Editor Character Oriented) on Caltech's PDP-10 back in 1975. There were no glass ttys, just DECwriters and ASR-33s (ugh). I.e. TECO was a line editor.

A couple years later, ADM-3A's arrived. And so did a TECO macro that turned TECO into a screen editor! Oh, what joy!

Isn't it a amazing that a macro could turn a line editor into a screen editor?

I also used TECO on my H-11 PDP-11 computer.

Hi HN,

I’m Javier, a solo indie developer from Spain. I’ve been working day and night on TestSCS, a study platform built to help candidates prepare for the official healthcare exams of the Canary Islands Health Service (SCS).

The platform includes over 54,000 official questions, grouped in 116 categories and offers 7 study modes like flashcards, randomized tests, or topic-based practice.

You can check it out here: https://www.testscs.com Just click “Prueba gratis” (“Free trial”) to start using it.

It’s fully in Spanish, aimed at a very specific public exam niche — but I’d love any feedback from this community on structure, UX, or ways to improve it technically.

I built it using Next.js, React, Vercel, and Android Studio for the mobile version.

Thanks so much for reading.

I'm really fascinated by this.

This looks to me like a great way to log claude code interactions.

Is it just me that cannot figure out a way to log the prompts and responses when using Claude Code?

If I look here I see nothing about a logging switch (beyond --verbose which is different). I'm surprised I cannot tell it to write this to a per session file.

https://docs.anthropic.com/en/docs/agents-and-tools/claude-c...

It is interesting because my daughter uses my claude account on another computer and I can see her prompts and she can see mine. I get nervous when I go down a political rabbit hole that she will get freaked out, but so far so good. Claude does keep a "history" there. But, not when you are using the code tool.

There is one very good reason I can imagine why this would not be in the tool. If I'm billing a client at $100X and my final cost from Claude Code is only $X, then I suppose I would prefer that no one could ever ask for that information. Someday employers will, I bet.

Maybe there is an easier way, like scripting or capturing the terminal output directly?

With IPv4, clearing the DF bit in all egress packets and hacking on top of QUIC could give just enough of a wiggle room to make it possible to explore this between a pair of cooperating hosts even in today’s Internet.

Anti-DDoS middle boxes will be almost certainly unhappy with lone fragments and UDP in general, so it’s a bit of a thorny path.

The big question is what to do with IPv6, since the intermediary nodes will only drop. This bit unfortunately makes the whole exercise pretty theoretical, but it can be fun nonetheless to explore.

Feel free to contact me at my github userid at gmail, if this is a topic of interest.

I’m working on a product where the value proposition depends on users adopting a new behavior

If the perceived value for the behavior change is marginal, there’s no trick or tip that will make people change.

If the perceived value is high, you don’t need a tip or trick…other than to create the perception of high value.

It is worth noting that perceived risk is a massive factor. Price is marginal value for a B2B offering that requires changing accounting behavior. For consumers, price might be the biggest risk.

So why are your potential users resistant to changing behavior? Ask them and solve their actual problems. Good luck.

Cal Sailing is a good way to get on the water and learn the basics. You can learn dinghies, keel boats and windsurfing. After you're comfortable with basic keel boat crewing, you can probably get a ride on a boat in the Friday night beer races at the BYC. I started at Cal Sailing and eventually raced at the Rolex Big Boat Series at the St. Francis.

Larry Ellison started at Cal Sailing and Lowell North was dinghy chair in its previous incarnation as a UC Berkeley club.

Goofy fun place.

I started sailing in high school and I was fat and out of shape but I was good and I was told I could have been very good. The joy of sailboat racing as the comment above made very clear, it's a brain game. If you're interested you can learn to sail, and race, pretty much anywhere with water, most places have some club or group that is racing Lasers, it's a good place to learn, how fit you need to be depends how far you want to go but it's not the primary factor in being good as far as I can tell (I'm an ok sailor these days, but some of the folks in here are clearly very good).

We built Spara to fix the black hole that exists between a lead clicking “Request Demo” and actually talking to your sales team.

Today, that process is slow, manual, and expensive — especially for companies handling high inbound volume.

Spara is the first AI platform that engages inbound leads instantly, prequalifies them, shows your product in real-time, and books meetings — no human needed. It’s built for hybrid sales motions (AI + AE), with integrations into Salesforce, HubSpot, Chili Piper, and Slack.

Our AI uses your website, sales collateral, and training guides to handle complex buyer conversations — answering questions, sharing videos, even showing pricing. Think of it like a multimodal AI SDR that’s always on.

Some early traction: - TinyMCE 3x’d MQL capture rates using Spara vs Intercom - Fama went from 2.28% → 20.41% lead conversion on demo pages - Rho (a $100M business banking platform) cut no-show rates by 35%

We’re SOC 2 compliant, easy to embed, and customizable with Journeys to match your sales funnel.

We’d love your feedback — what would you want an AI sales agent to do for your funnel?

For reproduction of the MMB, cells undergo classical bacterial division where the genome is replicated and the cell divides. The difference is that this is happening in a sphere so the sphere doubles in size and then the entire sphere splits into two. This is commonly considered clonal reproduction (although there is an argument for if "clonal" truly exists...)

Because of this reproduction, it would take only several generations for most genomic heterogeneity to be diluted out and the whole consortium (i.e., single MMB) to become clonal. What this suggests is that MMB are purposefully maintaining there genomic heterogeneity, likely for evolutionary purposes.

As far as a comparison to the Portuguese man o' war, it is similar in many respects. The theory is that MMB have a division of labor, meaning one cells has a job of say, metabolizing acetate, and its neighbor might have the job of storing carbon, and its neighbor has the job of reducing sulfate for energy. This would mean MMB have specialized cells that have a specific function. There is evidence for this but it has yet to be proven. The cyanobacterium Anabaena has specialized cells called heterocysts that fix nitrogen, a difficult job in the presence of oxygen which is a by product of the other cells. This is a clear example of a cellular division of labor in Bacteria. But Anabaena can exist as a single cell, meaning it is not obligately multicellular, which MMB are.

I do not think there is much of a relationship to hydrazoans. MMB likely developed their multicellularity from an incomplete cell division that resulted in the daughter cell staying attached to the mother cell, eventually resulting in the current organism. Multicellularity is not monophyletic and has evolved independently across the whole tree of life. Some research cited within our article shows that a single mutation to a single gene can cause multicellular traits to arise in bacteria.

> It's not a standard if it only works with one specific implementation.

IMO, that's sort of what a standard is, but the words is not strictly defined.

I think you are trying to argue that it's not open. The source is on github, and does accept contributions, but effectively Google controls who can commit to it. Depending on your definition of open, that's a valid argument.

You can load those libraries from other locations, but Google search results won't be able to cache it because of the privacy concerns I mentioned in my top level comment. It's not "valid", but the only consequence of the invalidity is no caching, and that consequence is unavoidable given the privacy constraint. It still shows up in search results.

The Google javascript library URL serves with no cookies, is publicly cacheable, and is an identical file to what you can build from source on github.

I often think that for a government to convince me that they are serious about addressing a housing crisis, the first thing they need to do is determine what proportion of residential properties are not being used as a primary residence. It seems to me (looking at changes in the number of households to number of dwellings in my property obsessed country) that that proportion has been declining and policies should be introduced to encourage people not to remove residences from the permanent housing stock (e.g. higher taxes on short term rentals, second homes, empty homes, etc).
