Some animals have multiple hearts, for instance cephalopods, like octopuses & squids, have 3 hearts.

However, for vertebrates it would be difficult to evolve to have extra hearts, because they have relatively rigid bodies.

A heart needs a space in which to expand, so it is not enough for the muscles in the wall of a blood vessel to increase in size and become capable of periodic contractions. You also need for all the space around it to evolve in providing an extra cavity inside which the new heart will be able to move without interaction with the surrounding organs, like the pericardium provides for the heart. In vertebrates, it was possible to evolve the pericardium because it has not evolved from nothing. It has evolved from a cavity (the so-called coelom) that existed in the ancestors of vertebrates long before having a skeleton and long before having a dorsal chord and even before having a blood vascular system. The modification of the coelom into a pericardium was a simple change, while the creation of a new internal cavity would be a very complex change. Moreover, also the nervous system requires changes, to be able to control the new heart.

So such changes are very unlikely in an animal like a vertebrate, because any intermediate stages would result in an animal that is disadvantaged in comparison with its competitors, only the final stage, with a functional second heart would be an improvement.

In general the evolution of animals does not happen at a constant rate. When an animal reaches a well optimized structure, it can keep that structure unchanged for hundreds of millions of years, because any deviation would result in a less competitive animal, which would be eliminated without descendants. For instance, there are a few species of sharks that have changed very little since Triassic, more than 200 million years ago.

Great changes in the structure of an animal happen only when there is no competition, which allows the intermediate worse forms to survive and produce descendants. Such lack of competition happens when a natural catastrophe kills most competitors or when an animal succeeds by chance to arrive in a new place, where nothing like it lived before, e.g. when passing accidentally to a different island or continent.

Having said all that, Apple could easily have made it 16GB cleaned up the market place and nobody would be talking about Neo being under spec’d. But Tim Cook has to be a Tim Cook and squeeze every last penny of profit. ;-)

I think this has more to do with binned A18 Pro SoCs which enables Apple to do this with economies of scale. A later version may get the 12GB variant of the A19 Pro SoCs.

This is amazing. I have to test it with my reverse engineering workflow. I don't know how many people use CC for RE but it is really good at it.

Also it is really good for writing SketchUp plugins in ruby. It one shots plugins that are in some versions better then commercial one you can buy online.

CC will change development landscape so much in next year. It is exciting and terrifying in same time.

> “This partnership with Astound and Stonepeak is the next step in our decade-long mission to redefine what customers can expect from their internet provider,” GFiber CEO Dinni Jain said in a statement.

He really must think we are dumb. You sold the majority of the company, because you don't want it to be your mission any longer. Otherwise you would not have sold the majority of stakes. What a loser.

> How does he do it

He always promises something 3 years into the future. He uses the new money to keep the old stuff afloat. He mad SpaceX buy Tesla Cybertrucks when noone else wanted them. Now buy data centers.

Tomorrow he'll have a new idea, a new snake oil, new investors and his "BEAM transportion" company, totally real in 3 years, will buy shitty space data centers noone else has a use for.

> That strategic helium reserve was from WWI, IIRC.

That may have been when it opened but the current war machine has little use for dirigibles.

> I've heard it claimed that it was a massive oversight to sell that much helium at such a low price. Helium is a non-renewable resource. When it escapes, it just floats off into space.

Helium is produced within the earth by radioactive decay. It then gets trapped in the same pockets as natural gas, which is why it gets extracted along with the natural gas. But most natural gas doesn't undergo helium extraction. If we wanted more, we could do helium extraction on more of the natural gas. Not doing it releases significantly more into the atmosphere than was present in the reserve. But doing it is expensive so we only do it more if there is demand for more helium.

The first mistake was the government hoarding that much of it to begin with. It doesn't make a lot of sense to pay a high cost for extraction in an earlier year and then pay a high cost for storage for an indefinite period of time if you're already discarding (i.e. not separating) most of it and could just extract more once you actually want it.

The second mistake was unloading such a massive amount over a short period of time, because then you crash the short-term price and cause people to waste the thing you spent a lot of money to extract.

There's a much simpler explanation. I regularly see boomers with wireless "earpod" type earphones out and about. They're not cool any more.

Fashion is fickle and it's best to not pay any attention to it. Choose the right tool for the job. Sometimes wireless is better, like when running, sometimes wired is better, like doing serious listening in a quiet environment.

I dont agree with the writers reasons for doing a Phd, the opportunity argument always comes up and undoubtedly invokes fomo in young graduates.
I haven't found PhDs to be universal opportunity openers, they open some specific and interesting jobs but I think even there they are becoming less and less relevant.
Most of the people I met on my short PhD experience and in the workplace after were unremarkable and the remarkable ones would stand out just as well without a PhD anyway.

I don’t believe they have the relevance they once had and certainly don’t think they are worth the time and financial strain. Best thing I got out of my experience was no longer being intimidated by PhDs.

YMMV
PowerSchool: Entry vs. Execution
by Olsberg | 2026-03-14 08:59:20+00:00
Most discussions of the PowerSchool incident describe it as a compromise of a support account.

If you look at the chain of operations inside the system, it appears roughly like this:

Entry: compromised support credential
Execution: Maintenance Remote Support operations through the PowerSource support portal
System of record: Student Information System (SIS) databases

The support account did not access customer data directly.

Instead, operations were executed through the PowerSource support interface, which could trigger actions against customer databases.

In effect, the support portal functioned as an execution mechanism for operations on production databases.

This makes the incident less about direct database access and more about the execution authority embedded in the support interface.

Not within a PhD, but as a side project I work on a research project on wikiversity about grammatical gender in French. It does reference a bunch of books and academic works, like probably a hundred I guess. The most tedious work though is to check which nouns are used only in a single gender of do have some epicenic or specific inflection used in the wild and giving a reference that attest that when it's not already so consensual that most general public dictionary would already document the fact. For that the research refers to thousand of webpages. I'm glad that most of the time I just need to drop the DOI, ISBN, or page URL and MediaWiki will handle the filing of the most relevant fields. That's not perfect, it generates the output with many different models currently (some don't have an excerpt field), and some required fields might be left blank, url to pdf won't work, and so on. But all in all it make the process of taking note of the reference quick and not going too much in my way. Creating a structured database out of it can certainly be done later.

I put off adopting popular agents for most of 2025 primarily because there was no agent-agnostic path to first-class Emacs integration. That changed with ACP (https://agentclientprotocol.com), thus I started working on agent-shell.

I'm happy with how the integration is shaping up, enabling me to have my cake and eat it too (Emacs + AI agents).

I wrote an agent-shell post recently with the latest changes https://xenodium.com/agent-shell-0-47-1-updates

True. I think the novel point is that on average, the emitter just isn't emitting. Normally, you can have a very simple piece of equipment that can pick up the fact that a signal source is emitting something, but then you need to get a more specialised piece of equipment to actually collect and decode the transmission. This just raises the stakes to having to have the specialised equipment to see that there is a transmission at all.

Exactly, 8 years ago last summer. Today it still happily recommends me take the "fastest" route through a street that's under construction for 2 months now in the biggest city in Serbia. A week ago it happily tried to take me through a closed off tunnel that is actually marked as "no traffic due to road construction" on the map (at least graphically, the metadata is likely not correct).

I am not holding a grudge at all: any map data is going to be out of date due to things happening live. Keeping it up to date in the entire world is a hard problem.

But they are not a panacea, and I frequently nudge it to better routes instead of the ones it recommends (I only watch out for live updates from them like a crash or new roadworks somewhere).

This is far too general of a philosophy to be applied in the dark. You can't say, without any familiarity with what the actual software looks like whether a rewrite is the best way to proceed. There are plenty of projects that get bogged down in the inertia of a system that wasn't built right in the first place.

Also, modern AI is only a few years old at this point. Whatever has been built so far is hardly load bearing.

I agree. I share your situation and comments.

I did look into the complaints and went direct to the source: My kids. ONe actively loves it. He seeks it out. I asked him about the author's complaints. He agreed its slow but didn't seem to bother him. He's not particularly patient, so this part was surprising based on the article.

Looking at it another way, 128 bytes gives you 1024 bits of state, or roughly 2^1024 (10^308) distinct states, still far more than the number of observable atoms in the universe. 128 bytes may be a tiny amount, but the real skill is in finding how to represent the necessary states.

Warden is interesting. Agents will curl websites, and not humans so returning a markdown structure of that page seems like the best.

Simlar to how everyone started optimising their pages for SEO, pages must be optimised for agents too, and its just simply detecting curl requests and returning structured files with internal linking to other pages.

It should basically be able to navigate the website like a file system. curl to the home page returns basic content with the basic sitemap structure, sitemaps ideally could have a description and token length of that specific page so agents can hit the sitemap route and know all pages/sub pages of the website.

Ideally if we can identify headless requests to a website to then return a markdown, with internal linking kind of layout then that'll be much better for agents to view websites.

Although yes there is firecrawl and cloudflare's new fetch apis, models will default to using curl or fetch on websites, and websites are not going anywhere, agents might need navigating websites more than us humans so it oculd be optimised for it.

That sounds like a way to not get any progress. The way I'm used to this sort of thing happening is some company brings in a new proprietary standard, makes bank, then all the competition bands together to form an open standard to try and stop them. There is a bit of a tick-tock feeling as consortiums use more open and accessible standards to slowly lever power away from incumbents.

It is interesting to just glance at the history of USB [0] through that lens was originally developed, and it is interesting to see that as I would have predicted the group of companies that developed USB (MS, IBM, Compaq, etc) seem to be disjoint from the companies listed as precursor technologies (looks like that was especially an Apple-led consortium of hardware manufacturers organised around firewire [1]).

“You are demonstrating that you do not trust the relationship enough”

This is entirely rational when a relationship is not strong, and a misstep could cause it to sour in a way not easily remedied. If I have to work with you, and can’t fire you, then I don’t want to foul the nest.

As my coworkers get to know me, they will drop the unnecessary politeness automatically, according to Zipf’s law. They will find I react well to straightforward communication once we have established trust.

Yes, but the force of a muscle does not increase with volume, but only with its section.

So a bigger heart would need to have thicker walls in comparison with its internal volume, which would increase disproportionately the volume of the heart walls, so for bigger and bigger hearts the useful internal volume that is filled with blood would be a smaller and smaller fraction of the total heart volume.

The lower efficiency of a bigger heart would require a higher contraction frequency to compensate, but the bigger a heart is the smaller is its maximum contraction frequency, due to the small speed of the propagation of an excitation through muscle cells and nervous cells.

I'm somewhat agreeing with it. CLI tools won't go away, since lines of text as an exchange format between tools is extremely powerful, especially with text based LLMs. However using an interactive TUI application to prompt agents will probably be less relevant in the future. E.g. if I want to build a web frontend, why wouldn't I just prompt and interact directly on the side I'm building?

Having completed SotTR on my MacMini M2 8GB, the game plays fluent at 1080p around 40-60fps without any issues. There are youtubers showing Cyberpunk on the Neo on lowest settings running around 50fps. Cyberpunk being somewhat special as it is visually so beautiful, that I would not recommend to complete it on a Neo.

It wasn't a list of Jews, it was a list of everyone from which Jews could be easily identified.

The distinction is important in this context, since the purpose of collecting and keeping the data wasn't specifically to have a list of Jews handy.

This is relevant to data collected by companies and governments today.

Consider a list of children with their parent names and the parents' preferred pronouns. You don't have a list of gays, but you have a list from which gays can be readily identified with high accuracy.

I am very curious where people who complain about the bots really get to see them.

The only website which became totally useless for me after the general availability of LLMs is OkCupid. It's indeed dead. The rest are fine.

What am I doing differently compared to everyone else?

I'm regularly using: telegram, whatsapp, wechat, hackernews, lobsters, reddit, opennet.ru, vk.com, pornhub, youtube, odysee, libera.chat, arxiv, gmail, github, gitlab, sourcehut, codeberg, thepiratebay, rutracker, Anna's archive, xda-developers.

facebook and twitter became broken for me, but not because of bots, rather because of the "smart feed" ("the algorithm"), which is hiding all posts of my friends and promotes incendiary garbage.

In other words, I am seeing enshittification full-scale, but not the bots.

As a kid, I had the hardest time understanding what a computer was. At 9 years old in 1977, I had a friend whose dad was a computer programmer. The friend tried to explain to me what a computer was, but I just couldn't understand it. We even took a field trip to a National Weather Service office where they talked a lot about their computers and showed us one that filled a room, but I still didn't understand. None of the explanations made it sound like anything other than magic happening in a big set of boxes.

At 12 years old in 1980, I bought Atari BASIC Programming (it wasn't yet called the 2600). Minutes after plugging it in, the idea of a computer clicked for me. That quickly led to getting bored with that game system and convincing my parents to buy me a "real" computer. Eventually that led to a long career as a software developer. Thanks for opening that door for me Atari BASIC Programming!

Duolingo was incredible to get my kids engaged with chess past USCF 1000

It also was super helpful in maintenance of a 3rd language spoken at home.

Maybe that's where the problem is. Perhaps it should be a requirement that an app must be winner in the consumer education market before it can be sold to the education bureacracy. If an app survived the cutthroat education app B2C market, you know it works well for B2E market
Ask HN: Is Another Editor Needed?
by gethly | 2026-03-14 09:10:39+00:00
I have been stuck with JetBrains IDE for years now. I have no issue with the software(except the period few years ago around the time when they changed the UI and the background tasks were going insane which made me stick with old 2022 version for years), just with the company. I never liked VS Code, the UI does not work for me. I was hoping Zed would be my way out but it lacks some things I require, which prompted me to start working on my own editor.

It's a low priority project but I did the heavy lifting already, mainly the layouting, so the basics are functional. My goal was to see whether I can make desktop GUI programs in Go and it turned out that is possible and quite easy.

I started seeing posts on twitter about how people dislike JetBrains and Zed and VS Code and whatnot over period of few months now as I started paying attention. So I am wondering what is going wrong with these editors? For example, Zed being the latest one, I'd expect it to be flawless by now, having the knowledge of the existing editors and what went wrong with them but it seems they still get negative feedback nevertheless.

Why do you think people are still not happy with what we have? What do these editors do wrong and should I put more focus into mine and maybe try to make it into something bigger?

PS: obviously i am not talking about TUI editors but GUI editors.

"Everyone says that they value directness, and from what I can tell the vast majority of people actually don't."

Well sure, of course we do. We (or at least, a lot of the readers of this who live in a US and similar economic and social system) have learned that it is virtuous and correct to say we value directness. But that's where it stops; it's just a thing that is right to say. Part of the current social interaction protocol. It's then widely understood that many interactions should not be hyper-direct.

What you have observed - people saying they value directness and then not exhibiting it - is the expected behaviour. This isn't a bug.

Yeah the main difference seems to be that he open sourced the games after he got very wealthy from them not before. So of course at that point you can easily feel magnanimous about bestowing gifts.

Open sourcing something from the start and essentially giving up any ability to profit from the use of your work when companies are often making huge profits from it seems less easy in comparison.

Only for you in SV.

Most of us aren't "$2 million net worth or $206,000/yr annual income for 5 years."

I'm glad the fee is lower again, but the fee isn't really what is stopping me from abandoning the US forever. When my mother dies, I'm probably gone. The US sucks in so many ways, and just trying to describe it all will end up dinging my HN karma at least 50 points :) For a bunch of "current admininstration haters" you guys sure do defend this shitshow tooth and nail.

For me, AI increased my NeoVim usage. Claude Code and Codex made me go full cli. I run several sessions in multiple tabs in WezTerm, using Tmux, Tmuxinator, and excellent tui based file manager named Yazi in left pane, opening files in NeoVim, running Claude Code in right split. With this setup I work on several projects in parallel. Use lazygit as git client. Everything in cli, super fast.

Initially I went with Cursor, but the terminal setup feels way faster, more natural.

Try Z Fold 7 with a grip case (one with a rubber band on the back to fasten it to your palm). Grip cases make phones in general much more usable on the go, but with a foldable, it's arguably what makes you feel safe using it for laptop-grade work while walking or without a surface to rest against.

Still not a laptop, but for me it's enough that I haven't used my private laptop since getting the Fold 7 half a year ago. Extreme portability can cover for a lot of other UX problems.

If they want to take them away, they'll have to rip my Sennheiser HD600 from my skull.

Legendary for their neutral, correct and pleasant sound, comfort, effectively forever durability, and being affordable to boot.

I can plug them to current or 40 year old hardware, and they do work. I use them with Topping DX3 Pro+[0] today.

It is no wonder they want us to instead adopt something active, crippled with bluetooth latency and dependent on lossy codecs, with a non-serviceable battery built-in.
