Yes, that’s correct, I do not want a vibe-coded freeway overpass, thanks.

We all need to get serious about the unavoidable, unsolvable fact that these tools produce output of unknowable accuracy. Some things require such accuracy, precision, and, importantly, accountability. LLMs are capable of none of these things. Refusing to be honest about this and take appropriate precautions will lead to disaster.

> Otherwise it was a no brainer complementary machine

Even as a main machine for most people. Heck I could probably even get away with it. I have my work laptop that's technically my "main" machine as I spend 8+ hours a day on it, and it's sufficiently beefy.

I hardly do much on a personal computer (not counting my gaming desktop), this neo would be more than enough for my non-work needs.

Granted, I don't currently have a need for it as I have my own MBA and an iPad pro, but if I had neither this would definitely be a no brainer and I could confidently recommend this over pretty much any off-the-shelf budget windows laptop to anyone who asks me "What laptop should I buy?"

I built SmartAgentKit to explore a problem that is becoming more common as AI agents interact with crypto systems.

Most agent implementations simply give the agent a wallet key. That works, but it provides no constraints on what the agent can do.

SmartAgentKit introduces policy-governed wallets using ERC-4337 smart accounts and modular policy hooks.

Policies are enforced on-chain and can include things like:
- spending limits
- contract allowlists
- emergency pause
- session-based access control

The system builds on:
- Safe smart accounts
- ERC-7579 modular account architecture
- Rhinestone ModuleKit / Smart Sessions
- Pimlico bundler + permissionless.js

Developers can also deploy custom policy contracts and install them in wallets.

> I wanted something BEEFFY! Specs wise but 13 inch at most.

One thing to bear in mind is bezels are a lot thinner than they were a few years ago.

~7 years ago, my daily driver was a Latitude E7270 - a 12.5 inch ultrabook with dimensions of 215.15 mm x 310.5 mm x 18.30 mm, 1.24 kg, 14.8 inch body diagonal

Today, an XPS 14 has dimensions 209.71 mm x 309.52 mm x 15.20mm, 1.36 kg, 14.7 body diagonal - and a 14-inch screen.

The 12.5 inch segment hasn't disappeared - it's just turned into the 14-inch segment.

A lot of lower division math and computer science courses now presuppose iPads or other digital pen devices for working through handouts during lecture. Printed handouts are often available at request, but not the expectation / default.

On the other hand, I've seen more professors — especially in the humanities, but also upper div CS — start banning devices in lecture partially or altogether. Complete distraction (scrolling Instagram, etc.) during lecture is extremely prevalent, and they keep citing noticeable improvements in engagement after banning devices. This also coincides with a shift back to less take-home assignments and more exam-style assessment since they want greater assurance people aren't completely offloading their cognition to LLMs.

You do have 13" options, though 14" is much wider. If I was going for 13" workstation, I'd go for Asus ProArt 13" with Ryzen AI Max 395 (if I got that right, there might be a plus somewhere) and 128GiB of RAM. They've got ROG Flow X13 with older hardware or Z13 with same hw as above, but that's a tablet computer instead.

At 14", thin-and-light gaming computers like Asus G14 or Razer Blade 14 look decent, or some of the workstation models from Lenovo or HP.

Still, for me, at 13/14", portability and battery are most important, so I am going with Thinkpad X1 Carbon atm (next gen should again allow 64GiB of RAM).

Extends to the extreme levels of SaaS-ification of fairly basic app functionality as well.

It's often simpler to build something you know than to integrate a 3rd party service, but it's highly frowned upon by a lot of devs and management.

Auth and analytics are things I'm thinking of - we have good tools to build these in-house. Also just running a database - never seen so many people afraid of installing postgres and a cronjob to back it up.

That sounds awfully similar to what Opus 4.6 does on my tasks sometimes.

> Blah blah blah (second guesses its own reasoning half a dozen times then goes). Actually, it would be a simpler to just ...

Specifically on Antigravity, I've noticed it doing that trying to "save time" to stay within some artificial deadline.

It might have something to do with the system messages and the reinforcement/realignment messages that are interwoven into the context (but never displayed to end-users) to keep the agents on task.

> So to me it seems that we don't want abstractions when trying to study certain things about a whole system. Instead, we want to view all of its components and then build our understanding from there. Abstractions hide the things that we care about.

I disagree. My experience is that most problems require a very thorough understanding of a specific slice of a system. It is rare (again, in my experience) that solving a problem involves understanding the whole system. This becomes more true the larger and more complex the system is. Abstractions allow you to ignore the irrelevant pieces and focus on what matters.

Maybe you mean it's a crime to professionally provide advice of this nature without a license?

It is generally not a crime to casually provide advice of this nature without a license. For example, if my friend tells me, "My stomach hurts!", it is not a crime for me to say, "Just grin and bear it, it will be okay." If they subsequently die of appendicitis, I'm unlikely to have legal liability. It would be difficult to characterize what I said as medical diagnosis or treatment.

Similarly, I can tell my friend, "Don't bother paying your taxes, that is a waste of time." This is legal speech. (Of course, helping them evade taxes is another matter.)

What is illegal is to hold oneself out as a licensed doctor, lawyer or engineer, or to provide professional services without a license.

Of course, chatbots operate at scale and give the impression of being professionally qualified even though they don't make specific representations to that effect. You're directionally probably right and I agree with you, I just want to nitpick about what is and isn't criminal.
Show HN: I built a CLI to sync AI agent skills and MCPs across coding agents
by ryanreh99 | 2026-03-04 19:30:36+00:00
Hi HN,

I built this CLI after having to switch between AI coding agents when token limits or quotas were reached. And had to port my MCP servers and skills across tools.

Instead of maintaining separate setups for each tool, everything can be updated through CLI and are synced through symlinks.
Currently supports Codex, Cursor, Copilot, Claude (untested) and Gemini.

Happy to hear feedback or suggestions !

So this is basically running on a phone CPU

I got excited for a moment thinking it might have an M4 or M5 chip, that would've made it interesting to tinker around with Asahi Linux.

But now it mostly just reminds me of a netbook. Its cool for people on a budget though, good to see Apple not just being this overpriced premium brand that it once was.

I think you're undervaluing touchscreen capability, which even the cheapest laptops offer now. Kids and non-tech folks have come to expect it by default.

Now that Apple is attempting to compete in this space, they'll have to pitch these folks on what macOS without touch capability offers over Windows with touch capability.

Maybe it will still sell well enough, maybe people aren't that stuck on touchscreens.

Metal is technically more elastic than an elastic band.
With a Young’s modulus of 69 GPa for aluminum versus just 2 GPa for ABS, metal has the "memory" to snap back from significant pressure. Plastic, true to its name, is far more likely to hit its limit and stay permanently deformed. (That’s why metal bars are used to provide “flexibility” to buildings. Concrete provides the strength)

> Everyone involved would be better of with a lower (or negative) income tax instead of subsidies.

That's quite wrong. The low income earners effectively pay no income tax - after deductibles and so on - further lowering the income tax would do absolutely nothing for them.

It'd be an economic and political suicide to lower taxes during high deficits while government money is literally blown up into fine dust in various wars around the world.

The "human in the loop at key checkpoints" pattern has been the most practically useful for us. We found that giving the agent full autonomy end-to-end produces subtly broken code that passes tests but violates implicit invariants you never thought to write down. Short loops with a human sanity check at decision forks catches that class of failure early.

The thing I keep wrestling with is where exactly to place those checkpoints. Too frequent and you've just built a slow pair programmer. Too infrequent and you're doing expensive archaeology to figure out where it went sideways. We've landed on "before any irreversible action" as a useful heuristic, but that requires the agent to have some model of what's irreversible, which is its own can of worms.

Has anyone found a principled way to communicate implicit codebase conventions to an agent beyond just dumping a CLAUDE.md or similar file? We've tried encoding constraints as linter rules but that only catches surface stuff, not architectural intent.

One of my the papers I share around a lot is "Nobody ever gets credit for fixing problems that never happened (2002)"[1]. I like it because it's not purely about software so the examples resonate better with some exec level people in other teams I work with.

Show HN: WooTTY - browser terminal in a single Go binary
by masterkain | 2026-03-04 19:32:07+00:00
I needed a web terminal I could drop into K8s sidecars and internal tools without pulling in heavy dependencies or running a separate service. Existing options were either too opinionated about the shell or had fragile session handling around reconnects.

WooTTY wraps any binary -- bash, ssh, or custom tools -- and serves a browser terminal over HTTP. Sessions survive reconnects via output replay. There's a Resume/Watch distinction so multiple people can attach to the same session without stepping on each other.

It seems to me that @tekne is comparing the LLM to a reference source. I took them to be pointing out that unlicensed-practice laws don’t crack down on textbooks, or reading the law for yourself (or even going jailhouse-lawyer or trying to defend yourself in court).

Rather, that the laws aim to keep the professional title commercially reliable, so that it indicates to the public that the person using it has proven some minimum level of expertise.

So the analysis would turn on whether a reasonable person would confuse ChatGPT for a practicing lawyer, or doctor, or whatever—not whether it communicated legal or medical facts.

Now, to my mind, the facts are the least interesting part of those professions—I pay those professionals precisely for their nuance and judgment and experience beyond the bare facts of a situation. And I think the ChatGPTs of the world do embellish their responses with the kind of confidence and tone that implies nuance/judgment/experience they don’t have.

But I do think @tekne was making a valid point.

> I’m confused, you’re talking about 16 GB of RAM but OP said:
Having only 8 GB

Look at the list of things they said they have open. Divide in half and it's still a lot because that set of running software is abnormally hungry. PostgreSQL, Slack, Docker, Brave, Cursor, and iTerm2 on my system puts RAM usage at 23.5GB on my system, and yet modern macs have extremely fast swap so most Mac users never even realize if they've filled RAM entirely with idle background software.
by runako | 2026-03-04 19:32:54+00:00
Sorry, I should have said that running that same stack on Windows/macOS Intel with 16GB resulted in tons of sluggishness in my experience. I would consider that a 32GB workload on Intel, so I was surprised that 16GB was enough for it.

To the major point of can it (Neo 8GB) run multiple programs at the same time, my experience would say it would have no issues doing so given what one can do in 16GB on lesser Mac hardware. (Maybe I am wrong and MacOS takes all 8GB for itself, but that seems far-fetched.)

There were many many milestones that are relevant to the current war.

- Proxy war waged by Iran in Lebanon, Syria, Iraq and Yemen.

- https://en.wikipedia.org/wiki/Assassination_of_Qasem_Soleima...

Arguably the bombing of IRGC meeting in the consulate-adjacent structure was not really "direct conflict". It was Iran firing missiles at Israel that was the first real direct conflict: https://en.wikipedia.org/wiki/April_2024_Iranian_strikes_on_...

Also if we want to split hairs Iran attacked Israel's embassy in Buenos Aires in 1992: https://en.wikipedia.org/wiki/1992_Buenos_Aires_Israeli_emba...

"In April 2024, Argentina's second highest court ruled that the Iranian government was responsible for the bombing, and that it was carried out in retaliation for Argentina reneging on agreements to transfer nuclear material to Iran. The ruling also characterized Iran as a terrorist state"

The A18 Pro performs about on par with an M4 in terms of single threaded performance, and a little better than M1 in terms of multi threaded performance.

The MacBook Neo has one of the fastest processors on the market for single threaded tasks, which is what has the most impact on how "fast" a processor feels for day to day usage.

Netbooks had processors that were glacially slow.

Historically, availability was very different between the two countries when we're specifically talking about purchasing SIMs for questionable activity.

Physically acquiring the SIMs is only one part of the process as they're pretty worthless without going through the activation process.

Prior to this year in Mexico (which introduced ID-based regulations around SIM purchase/activation), you could buy a SIM at a remote gas station, a data package in cash, and activate it without giving your name/email/etc. Now, in 2026, you have to show an ID/passport to do that.

The U.S. doesn't have a federal regulation (as far as I know) for this. That level of network protection is usually at the provider level. However, activating the SIM almost always requires an email or existing phone number and not just purchase/possession of the SIM+top-up card. Purchasing the top-up card sometimes can be done in cash, other times requires a pre-paid debit which has its own limitations/regulations due to a mix of KYC/AML. But applying said top-up card usually still requires at least some form of identity verification. For some of the top national providers, and I'm not sure what model they use to gauge risk to make this decision, they even require an SSN (for prepaid!) and run some form of a check on you (I'm not entirely sure if it's a soft credit check or what).

To give you the inverse perspective, an OG blogger named Steve Yegge made a list of five essential phone screen questions:

https://sites.google.com/site/steveyegge2/five-essential-pho...

Question three is this:

Last year my team had to remove all the phone numbers from 50,000 Amazon web page templates, since many of the numbers were no longer in service, and we also wanted to route all customer contacts through a single page.

Let's say you're on my team, and we have to identify the pages having probable U.S. phone numbers in them. To simplify the problem slightly, assume we have 50,000 HTML files in a Unix directory tree, under a directory called "/website". We have 2 days to get a list of file paths to the editorial staff. You need to give me a list of the .html files in this directory tree that appear to contain phone numbers in the following two formats: (xxx) xxx-xxxx and xxx-xxx-xxxx.

How would you solve this problem? Keep in mind our team is on a short (2-day) timeline.

In Yegge's case, he explicitly does NOT want a hand-written program, he wants the candidate to suggest a CLI tool, e.g.

grep -l -R --perl-regexp "\b(\(\d{3}\)\s|\d{3}-)\d{3}-\d{4}\b" > output.txt

———

So...

These questions aren't good or bad unto themselves, but when the person asking is engaging in "Guess the answer I'm thinking of," don't beat yourself up if you guessed wrong. Your answer might be prized by someone else with an enormous amount of experience hiring engineers.

It will benefit from a full amount of memory for sure, but AIUI if you use system memory and mmap for your experts you can execute the model with only enough memory for the active parameters, it's just unbearably slow since it has to swap in new experts for every token. So the more memory you have in excess to that, the more inactive but often-used experts can be kept in RAM for better performance.

I see a lot of folks lamenting how Yegge has ignited a fire under leadership for egoless, factory worker style engineers. I don't think many would care much otherwise, but his post here is lamenting AI is not enough of a factory worker yet. On a site mostly populated by folks who put most of their lives into becoming skilled professionals, hearing "we think your work should be the kind of work we send to the cheapest, least-developed places on earth" like factory work is disheartening. Of course, it mostly seems like Yegge is here to make money off meme coins and selling Dolt plus his vibe-authored book, so why would anyone take this seriously?

I mean, he can't explain what he's building except pickaxes to make more pickaxes, so it's a bit suspicious. It's just incredible how much impact he has had with this little hustle, given his products are basically turtles all the way down.

From your link:

Essentially the bottom cover of the MacBook Air becomes one large heatsink

Anyway, the author claims:

you are the type that likes to work with the MacBook Air on your lap it will be quite a bit more toasty than before.

Does toasty mean extremely hot?

The Apple M4 CPU is, if I recall correctly, capable of converting 20 watts of electrical energy in to heat, at full throttle.

Is that likely to bring the back plate or a MBA above 45 degrees?

You’re probably right, with sustained workloads it could.

Everything’s a trade off.

It's not merely a matter of detainment or deportation. Racial minorities, not just immigrants, face intimidation tactics. These guys are walking into schools, they're walking into social security offices, and courthouses. They stand around menacingly just to scare people. They harass random passerby's on the street, or in the grocery store. You would feel unsafe and stressed if this happened to you, no matter your circumstances.

I mean, to some extent, you're not wrong, but if a Democrat were in office right now, we wouldn't be actively fighting the rising tide of solar power.

At present, the bare economics of it, without any subsidies, put solar as the most cost-effective new power capacity to add.

Last year—2025, the first year of Trump's second term—something like 90% of all new generating capacity in the US was solar. Even with his active antipathy toward it.

There no longer needs to be a massive movement willing to pay more for energy just to get it decarbonized. All we need is for the fossil fuel industry and the people in its pay to get out of the way.

I’m sure this is true to some extent, about the lawyers. But also, I wonder (aka I don’t have any data to back this up, it is just based on random stories I’ve heard) to what extent people “I’m right but can’t afford the lawyer time” as a sort of pride maintaining excuse. Or to what extent lawyers use that as a soft-no to reject clients that they don’t think have a strong enough case.

Which isn’t to say the world is fundamentally just. Just, in some case the laws are legitimately stacked in favor of the big guys, or you sign a contract without carefully reading it, etc etc.

You forgot an important difference: the macbook neo has the A18 Pro chip (2 performance cores + 4 efficiency cores) whereas the macbook air has the M5 chip (4 performance cores + 6 efficiency cores)

Also the A18 Pro chip has a 5-core GPU whereas the M5 chip has 8 or 10.

Personally, the only dealbreaker in the list you posted is the amount of RAM.
macOS 15 uses ~5GB on startup without any app open. I'd be swapping all the time on 8GB of RAM.

The smoke over Tehran has yet to clear, but a more pervasive fog is already settling over the legal and moral justifications for Operation Epic Fury. On February 28, the United States and Israel launched a decapitation strike that reshaped the Middle East in a single morning. While President Trump and Prime Minister Netanyahu frame the operation as a necessary preemptive blow against an "existential threat," a glaring question remains: where was the evidence of an imminent attack?

> And yet same specs iPad + Magic keyboard will cost you twice as much

It's not about specs, it's about capability. You compare the Neo to the wrong iPad.

The base model iPad + keyboard folio match the MacBook Neo price, which seems to be intentional. iPadOS requires less resources to run but is functionally equivalent outside of being able to run arbitrary programs.

Which makes me wonder who the Neo is for. If someone wants to build software they should be paying more money. The average person is fine with an iPad, and it will even give them a touchscreen, the Neo won't.
