if you've made it to 10 years, that's a really nice problem to have (or maybe a really boring problem to have). But if you're just starting out, I want to prevent you from making all those decisions when you could really be focusing on your startup instead.

So I'm trying to encourage you to consider picking a platform and just sticking with the tools of the platform rather than bundling it yourself together.

Hi HN,

I’ve been building a small social network where the feed is always chronological — newest posts come first, always.

It’s not 100% algorithm-free (there’s still filtering to avoid spam or abuse), but the core idea is that *every user has a real chance to be seen*, even with zero followers.

Most of the current content is in Portuguese, but I’d love feedback on the concept, UX, or anything else.

Thanks!

It seems like the ranking of likely success in the next 10 years is

1. Commonwealth (tokamak w/ high temp superconducting magnets)

2. Helion (field reversed configuration, magnetic-inertial, pulsed) ....

?. Wendelstein (stellarator)

Maybe stellarators will be the common design in 2060 once fabrication tech has improved, but for the near future I think its going to be one of the first two.

Fair, but `n log n` definitely is the historical "good enough to actually sleep at night" in my head, every time I see it I think of the prof who taught my first CSC course and our data structures course due to how often it came up.

Also, the wise statement that 'memory is fairly cheap compared to CPU for scaling'. It's insane to see how often folks would rather manually open and scan a 'static-on-deploy' 20-100MB Json file for each request vs just parsing it into structures in memory (where, for most cases, the in memory usage is a fraction of the json itself) and just caching the parsed structure for the length of the application.

Since the article opening sentence and headline don’t say it: The breakthrough is the plasma “triple product,” literally just the plasma temperature (in keV) times particle density times (confinement) time. The Lawson Criterion. https://en.wikipedia.org/wiki/Lawson_criterion

A useful fusion power plant needs a triple product of at least about 3e12 keV * s * m^-3.

They weren’t fusing things (at least, not much). This is a figure of merit that allows you to compare, across all the different fusion methods, how well you would be able to fuse the plasma if you were using burnable fuel such as deuterium and tritium (isotopes of hydrogen that have one or two extra neutrons).

That seems exactly why it happened.

Why should a platform allow sharing ways of violating its terms of service? Sure, any tech savvy person will be able to figure it out, but business are businesses.

Should supermarkets allow you to ressel coupons in their premises for a profit? Because he's 1. monetizing the video, 2. being sponsored by a third party in the video and 3. showing ways of circumventing the platform TOS.

He could remove that frame where he shows the yt plugin, but he's using this to farm engagement.

> There is no cost to anyone if someone installs Arch without being an expert in the CLI.

Actually there is. But the cost is in the future when we have fewer wizards ;)

(Just had to be a little snarky lol. I know you agree)

Part of being a "Senior" in any field is helping those below you. Just think back to all the people that helped us get to where we are today! Yeah, we put in a lot of work ourselves, but it would be insane to have such an ego as to believe we did it all alone. There is no self-made man. No one can pull themselves up by their bootstraps. Nor are there giants' shoulder's to stand upon. Those are just a bunch of normal people standing on one another's shoulders wrapped in a trench coat.

It turns out that at a certain point, money can buy time. Do I fix the leaky tap myself, or hire a plumber? After electricians rip up my basement drywall (perfectly reasonably -- I was getting solar panels installed and the electrical panel needed to be upgraded) do I fix it myself or do I hire a professional drywaller?

To be fair, some of the time I spent on this came away from Tarsnap. But less than you might imagine.

It’s not obvious how many casualties the US itself would tolerate before going nuclear.

In circumstances where there were only a couple thousand American casualties, and those were incurred as collateral damage rather than as primary targets, it might make sense for the US to respond with conventional airstrikes and for Russia accept those and not escalate further.

This would depend a lot on the individual president though, like I could imagine Trump/Obama being much more risk averse than personalities like Bush 2 or JFK.

Yeah it's always been hallucinated repos. It's easy enough to verify - do a google search on the repo name itself and see if it's ever been mentioned or used anywhere and if it matches what ChatGPT thinks it was suggesting. And check to see if the owner of the repo exists and if they do, check their repositories to see which programming languages & topics they favor and see if it matches or not.

RedwoodSDK is the successor to RedwoodJS. We've rebranded RedwoodJS as "Redwood GraphQL" and built this new thing from scratch. We are the same people with the same ambitions, but more focused. With a narrow niche. I believe that a framework requires a platform to be competitive today.

Because of AI, the difficulty in writing code is greatly reduced. And because of platforms, the difficulty of shipping to production is greatly reduced.

That combination can be really great for your velocity when trying to build a business.

Completely agree. And to add on, many are complaining about not having time and working, but you're working more because you're spending more on eating out, DoorDash, etc., then your waistline expands, health problems creep in, and so on and so forth.

The American version of how we eat is abject nonsense - DoorDash expensive food that's worse than what you can cook for yourself, incredibly unhealthy, and then in between doomscrolling Elon Musk's latest Tweets and your ever expanding waste line complain that there's no time to do anything and you just can't cook because it takes "2 hours to go to the grocery store". Americans don't even go out to eat and take their time and enjoy life and the culinary arts because they're in a rush.

Unfortunately our car-only infrastructure reinforces this learned helplessness, and so we have crappy food quality, obese people and massive healthcare costs, and antisocial behavior as people spend their time terminally online.

Sorry for the rant to anyone reading. Don't take it too seriously. It just drives me crazy that we have such a great and vibrant country and we refuse to truly live in it for some god forsaken reason.

It's very rough, though. I know many (East, South, Southeast) Asians who can drink milk just fine. But I -- white with European ancestry -- am lactose intolerant. Not a really useful rubric from my perspective, and I think if a doctor (re: your "medical context") were to say something like, "you're Asian so your stomach distress is probably caused by dairy" or "you're white so we should look deeper for some unusual cause of your stomach distress", I would look for a new doctor immediately.

> Maybe the things I can't pay attention to aren't worth paying attention to and I should be working on something else.

When these things are vital things like feeding yourself, going to work, of driving, this absolutely does not apply. Without treatment, I often cannot even get myself to do things I want to and are fun. ADHD isn't "I can't pay attention to a boring movie", it's executive dysfunction.

Some animals have subspecies. Humans don't. This is something that's widely misunderstood popularly but which is indubitable biologically. For example, many people are not aware that there is vastly more genetic variation between different breeds of dog than there is between any two groups of humans.

But regardless, the more important point is that whatever biologically-motivated categories humans might be grouped by would not correspond to 'races' as normally understood.

It has taken over the lexicon of most major sports to the point I can barely stand watching most of them now…

NFL broadcasts lean so heavily into betting odds, parlays, prop bets, everything… it’s so obnoxious hearing about X player hitting the over, only to go to a commercial offering some free money if you place a certain sized bet.

I really hope (but am not holding my breath given how much money is involved at this point) they ban sports betting advertising in the future.

The issue with this is that it would be quite difficult to replace the functionality of the existing VC-25As.

They have comprehensive anti missile and anti air counter measures.

They are completely electromagnetically hardened which doubles to both protect against electronic warfare, worst case scenarios like nuclear attacks, and to shield against spying on internal wireless comms.

They can fly for up to 15 hours without interruption at full fueling and full weight capacity.

On top of their long flight time they can refuel mid-air off USAF tankers if need be (fighter jet style).

They stock two separate galleys for food preparation with supplies for 2000+ meals as well as weeks worth of fresh water.

They have a full onboard pharmacy, diagnostics lab, and surgical center including a full size operating room and all necessary imaging technology. With all accompanying staff of course.

They don't require any support upon landing and supply their own retractable vehicle mounted stairway and baggage loaders which are stored in the aircraft. Strictly speaking all they require is a runway. They can deal with everything else on their own.

And that's before you even start to consider spaces for staff members, a dedicated seating area for the press pool that travels with the president, conference rooms, etc as well as bathrooms, showers, sleeping arrangements, etc for those on board.

-----

Switching away from the VC-25As to a much less capable/independent plane will massively widen the attack surface for targeting the president and will introduce so many avenues for espionage or assassination that simply haven't been possible in the past thanks to the VC-25As.

There is a sort of way around this.

You can generate phone numbers with embedded DTMF codes - including pause and wait.

For example `<a href="tel:+447700900000,12#">` will pre-fill the dialler with that number. After dialling, it will pause for a few seconds then sent DTMF 1 2 #.

You can make it slightly interactive with the "wait" command. For example `<a href="tel:+447700900000;#9">`. The semicolon should* give the user a prompt asking them if they want to send the DTMF `#9`.

Of course, this is no use if the app is to be used interactively. But if you know that you need to send a predefined sequence, it is useful.

> it isn't even that common a word, and all of a sudden everyone it seems like everyone using it

In this particular case, it is a very unique word. I don't know of any that even come close to meaning the same thing. People with a desire to express their observations may find only a single word to do so. FWIW, I was familiar with the word already and I've similarly notice a seeming uptick in use on this site.

> For instance.. why did everyone all of a sudden care so much about the price of eggs during the last election? There's no way that was entirely organic.

I see your point and I think you're on the right track. It's memetics. Egg prices being high is a meme. The public spat between Donald Trump and Elon Musk being a kayfabe performance is a meme. Neither is necessarily an engineered meme.

(Note also that 90% of our deterministic simulation testing is done primarily by the VOPR, TigerBeetle's own deterministic simulator, which we built inhouse, and which runs on a fleet of 1,000 dedicated CPU cores 24/7. We also use Antithesis, but as a second layer of DST.)

People say that it's a practice.

A few years ago I was determined to practice, and it was hard, and then it became easy, auto-relaxing, like a cheat.

I lost that practice and now it's hard again.

I think GP is right to question technique vs. attention - I think we don't know much about the answer.

But a point I recall in Nestors book is that there isn't really a lot of scientific study on breath - there is much more study on specific diseases, and e.g. teeth have a full profession of study and development that the everyday act of breathing doesn't have (even though these might be highly related!).

<Opinionated> Some of the best references about breath today are not scientific, but written in the oldest books that survived in different cultures - and anyways, how much does the specific mechanism matter?

Watch this space though - science is catching up! </>

> Another useful command to check for open file descriptors is lsof,

... but the one that comes with the operating system, on the BSDs, is fstat(1).

> 10u: Another file descriptor [...] likely used for additional terminal interactions.

The way that ZLE provides its user interface, and indeed what the Z shell does with the terminal in general, is quite interesting; and almost nothing like what one would expect from old books on the Bourne shell.

> it tries to open more files than the soft limit set by my shell

Your shell can change limits, but it isn't what is originally setting them. That is either the login program or the SSH daemon. On the BSDs, you can read about the configuration file that controls this in login.conf(5).

Ye well there is room for improvements.

I have done sports betting like three times, when I realized the odds were bonkers, and retrieving the money after winning was an extreme hazzle that took weeks with photocopies of passports and gas bills and what not. Paying the bets took a minute.

I mean, online betting is a shady business. Physical casinos at least have some sort of brick wall to bang your head against.
by abelanger | 2025-06-06 21:00:27+00:00
This reads more like a pitch for open-source than anything else.

> Switching out something, even if it's open source and self-hosted, means that you're rewriting a lot of code.

The point of something open-source and self-hosted is that it resolves nearly all of the "taxes" mentioned in the article. What the article refers to as the discovery, sign-up, integration, and local development tax are all easily solved by a good open-source local development story.

The "production tax" (is tax the right word?) can be resolved by contributions or a good plugin/module ecosystem.
Show HN: Asteroid Impact Probability Tool
by dremy | 2025-06-06 21:00:47+00:00
Our B612 Asteroid Institute team launched a demo of ADAM::Impact Probability, a new tool to simulate and visualize potential impact risks from near-Earth asteroids over the next 75 years. Hear from one of our engineers on how it works and how you can use it in the link. You can go directly the impact probability tool at b612.ai but you might want to learn a bit about it first unless you are an astrophysicist already :-)

In a physical betting space, usually located in casinos, I can also get free drinks. There’s also other stuff to do and it requires actual physical effort to be there and bet all the time.

Online sports betting is a mug’s game.

I made a few hundred dollars and have quit for a couple of years now once I learnt that they can kick you out for doing too well.
by LegionMammal978 | 2025-06-06 21:01:06+00:00
Yeah, examples of 'small' interpreters (including 'small' self-interpreters) have always made me uneasy when they depend on a powerful runtime environment. E.g., in the limit, you can create a language where the 0-byte program is a self-interpreter, and all other programs are interpreted as Python or whatever. You can then point to "look how small the description is!" when it's really just sleight of hand. To put it as a hot take, bootstrapping is very overrated.

Of course, every human definition will similarly hide complexity to some extent, so there's no real way to win.
by jmyeet | 2025-06-06 21:01:46+00:00
Yes. And I reject that claim.

Big tech companies are both doing mass layoffs AND hiring. How does this fit the narrative that the tax change is at least in part responsible? The new hires still have the same deduction issue, right? So what impact does this really have?

Think of it this way: if this passes, will the layoffs end? Or reduce? Absolutely not. All this does is give line the pockets of shareholders. That's it.

I'm a big fan of tying certain benefits to NOT doing layoffs. This can include:

1. You get this deduction only if you've fired fewer than 1% of your workforce in the last calendar year;

2. You don't get to sponsor for an H1B if you've conducted ANY layoffs in the last calendar year; and

3. The tax deduction only applies to unionized workers.

And while we're at it, let's roll back this ridiculous tax structure where IP can be "sold" to a subsidiary in Ireland and then royalties paid.

My inside information is both outdated and minimal, I was there for a short time a few years ago.

As far as I know all the development work on client projects was done by developers in India. I was too far removed from the details to know quite how they were employed and paid - I literally never had any interaction with them - but I suspect this is the main source of the LinkedIn employees.

As far as I know customers were aware apps were being built by human developers, the "80% by AI" was prominent on the website and the sign up process but it was never claimed the whole thing was automated.

It looks like Craig Saunders joined only a year ago, in June 2024, which is long after I left. Given how much AI has advanced over the last few years, and given his LinkedIn shows he previously held a senior AI role at Amazon, I wouldn't be remotely surprised if he and other employees built some impressive tech demos over the last year or two.

Regarding Natasha assigning developers to projects, I don't know to what extent it was really automated, I wasn't involved in that.

So (if we take your interpretation at face value) you could call it a 'presidential power grab', or maybe even an 'executive power grab' (if we stretch things and assume power is being transferred away from executive departments subject to greater oversight), but 'federal power grab' still doesn't make sense. No power is being grabbed from or by the federal government as an entity.
by freedomben | 2025-06-06 21:03:25+00:00
Same (though s/plex/jellyfin/g). I was a long time subscriber to CBS (now Paramount+) and many others, but I've slowly cancelled them all as their quality is utter shit, and now they've started rolling ads even at the high paid tier. Using an unmodded Chromecast w/ Google TV on a stock TV, I couldn't get Paramount+ to stream any of the newer Star Trek without falling back into a horrifically obnoxious constant shift in color tone that the internet informed me is a "feature" of their DRM to sabotage the quality if somebody is trying to record it. I was just trying to watch it, after paying for the damn service! Absolutely nothing in my setup was modded or sus in any way. Guess what, I still ended up watching it, but after cancelling their service and figuring out a way outside of their system.

The only streaming service I have left now is Netflix, which does work remarkably well, though how long they stay "ad free" remains to be seen. The first time they show me an ad, will also be the last time they show me an ad.

The fact you can’t pretend _is the point_. A blanket policy of “no and never” that works well for other addictions or compulsions can’t be applied to food. :)

As a counter-factual, imagine if every time you wanted to smoke you had to decide if one particular type or brand of cigarette was good for you.

Probably that free software never actually dies or even really degrades in the traditional sense. Given decades of time, even small incentives to make things better, like the reputational increase one gets from contributing to good FOSS projects, compound really heavily.

Take the Linux kernel as an example. If you were a kernel hacker, even a minor one, from the 1990s, it's quite likely you could parlay that experience into a good job today doing something similar. Those 50-100 hours decades ago have compounded quite nicely for you. But your contribution didn't decay over the next 30 years - worst case scenario, it stayed exactly as good as it was when you stopped, and best case scenario it's been substantially rewritten and incremented upon.

That's how I explain it to myself at least.
by xorvoid | 2025-06-06 21:03:57+00:00
You’re right. I think it ends up working out to a 4096 page on x86 machines, that’s probably what I remembered.

Yes, _FORTIFY_SOURCE is a fabulous idea. I was just a bit shocked it wasn’t checked without _FORTIFY_SOURCE. If you’re doing FD_SET/FD_CLR, you’re about to make an (expensive) syscall. Why do you care to elide a cheap not-taken branch that’ll save your bacon some day? The overhead is so incredibly negligible.

Anyways, seriously just use poll(). The select() syscall needs to go away for good.

Fair enough, I’m by default deferential to our courts.

In this case, however, there is a simple solution if OpenAI doesn’t want to save data: don’t retain it in the first place. If OpenAI committed to privacy as a value, their protests would have merit. But in this case it sounds like they want the ability to retain the data as well as delete it despite being in the midst of litigation. That’s simply not a privilege anyone is afforded by the courts. (We’re also talking about the Times versus a $100+ bn tech giant whose CEO has direct lines to heads of state. There is no David to default sympathy to.)

It feels like gambling talk has largely replaced fantasy team talk on most broadcasts, and I wonder what role fantasy sports* played in all of this.

Did fantasy sports have a causal role as a gateway that slowly normalized gambling, or were they just reflecting that there has always been a latent thirst for gambling and fantasy sports were the only socially acceptable way to scratch that itch?

* not talking about “daily fantasy” stuff which was just blatant gambling pretending to be fantasy sports to exploit a loophole
