Imagine training a chess bot to predict a valid sequence of moves or valid game using the standard algebraic notation for chess

Great! It will now correctly structure chess games, but we've created no incentive for it to create a game where white wins or to make the next move be "good"

Ok, so now you change the objective. Now let's say "we don't just want valid games, we want you to predict the next move that will help that color win"

And we train towards that objective and it starts picking better moves (note: the moves are still valid)

You might imagine more sophisticated ways to optimize picking good moves. You continue adjusting the objective function, you might train a pool of models all based off of the initial model and each of them gets a slightly different curriculum and then you have a tournament and pick the winningest model. Great!

Now you might have a skilled chess-playing-model.

It is no longer correct to say it just finds a valid chess program, because the objective function changed several times throughout this process.

This is exactly how you should think about LLMs except the ways the objective function has changed are significantly significantly more complicated than for our chess bot.

So to answer your first question: no, that is not what they do. That is a deep over simplification that was accurate for the first two generations of the models and sort of accurate for the "pretraining" step of modern llms (except not even that accurate, because pretraining does instill other objectives. Almost like swapping our first step "predict valid chess moves" with "predict stockfish outputs")

> Featuring extensive connectivity to support a variety of workflows, Studio Display XDR includes two Thunderbolt 5 ports and two USB-C ports.

That is not extensive connectivity. That’s the bare minimum one might credibly expect.

If I were to consider buying a display like this, I would want at least two and preferably more inputs and at least a DisplayPort input. Not everything in the world is USB-C, especially when discrete GPUs are involved.

What I have wanted for a very long time for America:

1. The government cannot ban any speech in advance of publication (eg verbally making the statement; or airing; or publishing etc).

2. If proven in Court that the statement maker: (a) knew the statement was false; (b) made the statement for the purpose of influencing public opinion regarding a law or government policy or election; or for the purpose of marketing a product for sale to the public; then the penalty upon conviction is...:

here is the secret sauce: super severe penalty such as: imprisonment without chance of parole or pardon for 10 years unless you are an elected official or candidate for office, in which event life in prison; or loss of 50% of your assets; or something similar

In other words, keep freedom of speech but if you are intentionally lying to the public for the purpose of impacting government affairs or the sale of a product - then you are going to suffer an incredibly punitive penalty.

Yeah not sure if it's so necessary.

Everyone carries their phone. Power users (i.e. nomads who need connectivity in many different places) have lots of unlimited data plans available that are modestly priced (I've travelled asia the last few months and used e-sims for like $10 a month in each country). And that's a niche group, but even they have their phone as a hotspot. Downside is that it burns battery, but if you're sitting somewhere for any length of time that battery would matter, just plugging-in basically resolves that.

The vast majority of us are either at home, work, friends/family or a rotating set of a few local cafe's, all of which are in our wifi auto-connect list, and have their phone hotspot for the rare occasion there is no wifi.

Then for the powerusers you could just buy a mobile hotspot device as well, basically what your phone does but it's just connectivity + battery.

It's not as cheap a part as you'd think, estimates range between $100 and $300 extra per laptop, even though it seems like a niche thing for which alternatives at lower/similar price points (phone/dedicated device) already exist. So I'm not sure we're going to see it anytime soon. Maybe with Apple making its own modems now it'll happen in a few years. Previously it'd just make for a more expensive device for something few users need (and shipping cheap devices to everyone is a priority with their service business of $100b in 2025, more than Tesla with a market cap of 1 trillion)

Have you tried bringing it up with HR? If you explain why you try to avoid her while she's wearing them, they might ask her to stop wearing them to work.

Meta's own guidelines[1] say that you should "Power off in private spaces."

You can't always tell if you're being recorded since they can be tampered with to disable the LED. And from what I gather, the LED only serves to indicate of video recording, and not necessarily audio.

Yes, just like an Office Hierarchy there's an expectation that they respect the Rank - based on the caveat that the Officer/Manager doesn't confuse Rank with Authority.

I guess it depends on how you perceive "censorship". I wouldn't think of banning a misleading ad as censorship. My country, Greece, was under a military dictatorship for a few years in the 1960's and 70's, and censorship involved e.g. pre-approving all music, including not just song lyrics but also the music scores. Works by the two major Greek composers, Theodorakis and Hatzidakis [1] were banned outright and could not be played anywhere under pain of pain [2]. Obviously everything anyone wanted to publish in the press had to be pre-approved by state censors and any criticism of the regime, either written or simply spoken out loud, was punishable... you get the gist.

Not allowing advertisers to lie to advertise their product is I think not a kind of "censorship" one really needs to be worried about. They're free to advertise their product otherwise, they're just not free to lie to do it.

I feel silly making this elementary point, but freedoms can't ever be absolute in a society of more than one humans. Even in the US I bet you're free to drive, but you're not free to drive drunk. You're free to have sexual relations, but not with a minor. You're free to walk anywhere you like but not in other peoples' property and not on the streets with the cars (which btw is perfectly fine in Europe and it's rules about jaywalking that are "pants on head" for us).

These are rules. Societies have rules. They should have them. There's no problem with that.

And now my 16-year old self is very disappointed that I've grown up to be a conservative, establishmentarian fossil.

> he'd been offered a promotion, to an Engineering Manager role

Funny how this lateral move to another function is seen as a promotion.

I've done both for significant amounts of time, and rather than a blanket, utilitarian "dont become a manager", I'd go with the antithesis to that blog buried at the very end:

> So why am I still an EM [...] the main reason is that I enjoy my job

EM positions come in all sorts of shapes and sizes, and it's an entirely different function from that of a developer. I had tremendous fun being a manager in a couple startups, where left with lots of autonomy I could learn about, then experiment with better ways to deliver than "let's do 2w sprints" and ship shit. The human management was interesting, especially the continuous improvement side of things: it's especially exhilarating when you find something someone can do better and have a durable impact on their career ; it's especially tiring when you have to become something at the convergence of a psychiatrist, a referee and a nanny.

In large companies, the job isn't the same. You're stripped from autonomy and forced into a bureaucratic aspect of things. Dates are the main control dial that VPs have, so your main goal is to provide random dates, track random dates, make sure it's gonna be delivered at random dates, and make up excuses for why that date was not met.

After alternating a couple of times between the two functions, I figured development is what brings me the most joy, so I staid with it. But to each their own, and you might want to be a manager:

- if you have a true interest in the function, go fo it. There's a lot of learning to be done (the main problem with bad managers, I believe, is that they're thrown there because they were good devs, and they just make shit up rather than learn) and you'll discover things

- at the opposite side of the article's thesis, AI is a chance for you to innovate as a manager. The bureaucratic aspect I mentioned can be smoothed by it, and new tools mean a new way of working, so good times to experiment!

- don't just do it for the utilitarian side of things. Developing your career is important, but you also need to do it a sustainable way. Something I keep telling: it sucks to be good at something you hate. So do something you like.

- it is not my experience that pay is lower, Amazon paid SDMs more than SDEs, Microsoft pays them the same.

- titles mean very little. VP at MyFavoritePet who employs 12 people is not the same job as VP at Amazon. Principal (not principle - makes my eyes bleed every time) is harder to achieve at Amazon than at Facebook. Not because the job is more complex, but just because they define things differently.

The argument is that the mechanisms in use in the German IDs (and others like them) rely on trusted parties and/or trusted hardware, and therefore don't adequately assure anonymity. And this is in fact true; the trusted parties are among the ones you might want to hide the information from.

Trust is bad in security. It's not complicated to understand this.

You had two choices: 1) read the article or 2) be racist about Indians. You chose 2.

From the article:

> In October, two federal judges in the US were called out for the use of AI tools which led to errors in their rulings. In June 2025, the High Court of England and Wales warned lawyers not to use AI-generated case material after a series of cases cited fictitious or partially made up rulings.

I’ve got a M2 MBA and I love it. I can /live/ with Tahoe, would rather have Sequoia or something a little older (but keep the Password app!) I certainly /don’t need/ a touchscreen Mac laptop, which is what Liquid Glass seems to be designed for.

Having said that, I probably would’ve switched to some version of Linux many years ago if it wasn’t for the lack of business accounting software that was easy to set up. GNUcash isn’t it for me. Switching would’ve saved me a lot of money on subscriptions.

I could probably use Obsidian instead of NotePlan with a bit of work; I would just use it on mobile a bit less.

I have a huge tote box full of power bricks, most of them white Apple ones. I have a stack of 60-90W Apple USB-C ones too that I don't use cause they only have one port and are larger and worse than modern GaN units that can do 140W on one port while also pushing 30 or 60 on the others.

So, if you want one of mine, you can have one. On me. Because I'm fucking drowning in the things and appreciate not having to deal with another one.

Sure, my point is just that all of those schedules are arbitrary. We made them all up.

One way might require less rescheduling, and that's valid, but these discussion out in the world tend to go to "but everyone does X at Y time and it will be dark out!" as though this isn't all made up and changeable.

I also think that learnings from previous attempts decades ago may not apply as strongly today. In the US at least I think people's schedules tend to be much less fixed on the rigid 8am/9am to 5pm in-office schedule than they were 10 or 20 years ago. The number of people out driving at all hours of the day all week speaks to that.

The world used to revolve around everyone being in-office next to their phone during defined expected business hours. Today my mortgage broker is texting me from a coffee shop.

Age and identity verification can and should be done at the country level.

France has an ID service to pay taxes, and they have a network of possible ID verification systems. Like, you can ID through the tax system, or through the healthcare system. It works fine.

Implementing an API that uses the same to provide age verification is not rocket science.

If you need age verification for a website, say "smedia.fr", then you go there, then it makes you get an age verification token to "franceid.gov.fr", that guy gives you back a token, you send the token to smedia.fr which checks the token with franceid.gov.fr

I don't understand how this is even an issue.
Designing Search Experiences
by CShorten | 2026-03-03 15:32:04+00:00
In many software applications, Search is the core feature. The search bar is the universal interface for interacting with data!

So how should you think about designing user experiences around search so that your users are delighted to use your software?

What are the different types of search experiences you should be aware of as someone working in search engineering?

Also, whereas LLMs have typically responded to us with a wall of text, they can now respond with applications created from stacks such as HTML/CSS/JavaScript. How will this shape search experience design?

To clarify, I meant, model with Pro chip, not just Macbook Pro name.

For example, up until MacBookPro M2, MacBookPro M2 came with M2 Pro chip.

However, starting with M3, Apple lowered the MacBookPro MSRP to $1599, but its base configuration was downgraded to M3 chip from M3 Pro. To get the M3 Pro, you had to pay $1999. There's substantial performance between the two.

Same with M4. To get the M4 Pro chip, you had to pay $1999.

Now to get M5 Pro chip, it's $2199. Still a good value, but just saying it's a deviation from the trend.

yeah?

my job is basically self-directed. I'm expected to predict the future for what we as a business will need in 6 months to a year and become the expert in it now. lay the framework, prototype, sell to the larger org, integrate and move onto whatever else. This is in addition to the normal jira-driven feature/bugfix bullshit. I am looking at the problems we might run into then derisk them by figuring out what to build.

But I'm at a large org where timelines are about as flexible as jello. I think I'm also overqualified and underpaid so my boss just lets me do whatever.

Like I've been porting firmware from C to rust a day or two a week while I also am directing some more jr devs for our VP's latest product obsession.
Show HN: Exodus – we tracked 240 moves across companies to map the AI talent war
by fabioperez | 2026-03-03 15:32:52+00:00
Hey HN,

Exodus tracks who's leaving the big AI companies, where they're going, and what they're building. 240+ moves, 80+ companies, every entry sourced.

I used AI to track these after noticing the same pattern every week: someone leaves OpenAI, someone leaves Anthropic, a new startup appears, they get funded week later. A few things stood out:

- Google/DeepMind lost 58 people and got 13 back
- OpenAI alumni founded 18 startups worth $450B+ (TechCrunch calls them "The OpenAI Mafia")
- Half of xAI's co-founding team walked out
- Apple feeds Meta, Meta feeds OpenAI — there's a whole food chain

You can filter by company, role, seniority, or time period. There's a Sankey diagram and a brain drain chart.

The curation pipeline uses the same system I run for https://7min.ai. Every entry is checked against published sources.

Are we missing any patterns?

> Are they doubling down on local LLMs then?

Neural Accelerators (aka NAX) accelerates matmults with tile sizes >= 32. From a very high level perspective, LLM inference has two phases: (chunked) prefill and decode. The former is matmults (GEMM) and the latter is matrix vector mults (GEMV). Neural Accelerators make the former (prefill) faster and have no impact on the latter.

Show HN: A Write Barrier That Blocks Structural Collapse in LLM Reasoning
by persistentVlad | 2026-03-03 15:33:28+00:00
In multi-step tasks, LLM outputs may replace structured intermediate forms with scalar results.

Example:
(2 + 3) * 4 → 20

This removes structural decomposition and makes downstream reasoning dependent on a scalar result.

I built a minimal prototype that enforces admissibility before persistence using a write barrier.
The write barrier separates model output from persistent state.

Core mechanisms:
* Append-only lineage (no in-place mutation)
* Explicit proposal → invariant check → commit cycle
* Whitelisted structural transforms
* Deterministic invariant checks before commit

If a transform attempts to collapse structure (e.g., replacing a decomposed expression with a scalar), the proposal is rejected and never enters the lineage.

Important distinction:
Invalid states may still be representable as data, but they are uncommittable under the governed commit path.

This does not modify the model.
It constrains persistence architecturally around model outputs.

Arithmetic is used purely as a stress-test domain to isolate one narrow claim:
Certain structural collapses can be made impossible to persist.

Limitations:
* Domain-specific invariants
* Not a symbolic solver
* Does not improve model accuracy
* In-memory prototype storage
