It's not the ISA. Modern Macbooks are power-efficient because they have:

- RAM on package

- PMIC power delivery

- Better power management by OS

Geekerwan investigated this a while ago, see:

https://www.youtube.com/watch?v=Z0tNtMwYrGA https://www.youtube.com/watch?v=b3FTtvPcc2s https://www.youtube.com/watch?v=ymoiWv9BF7Q

Intel and AMD have implemented these improvements with Lunar Lake and Strix Halo. You can buy an x86 laptop with Macbook-like efficiency right now if you know which SoCs to pick.

edit: Correction. I looked at the die image of Strix Halo and thought it looked like it had on-package RAM. It does not. It doesn't use PMIC either. Lunar Lake is the only Apple M-series competitor on x86 at the moment.

I've been using the super minimalistic 0launcher (https://play.google.com/store/apps/details?id=app.olauncher&...) for about a year now.

Besides being a good, very simple, minimalistic launcher, it's also Open Source (https://github.com/tanujnotes/Olauncher), ad-free, and collects and shares no data.

What were the bugs? How were they fixed?

How do we know this is even what really happened? There was a big wave of complaints on Reddit about Claude's output quality, and reports of subscription cancellations piled up.

Many people suspect some form of load optimization and/or quantized models, or other cost-optimization strategies that were applied as the cause for degradation in intelligence.

Seems like the complaints became loud enough for Anthropic to bother looking into it. But with zero transparency, zero additional info around the issue, it's hard to trust Anthropic not to continue to silently optimize for cost.

Why pay $200 a month if your "productivity boost" can randomly turn into lobotomized output overnight?

No, the horn is in the middle, the capacitive horn only steering wheel existed on early builds of the model S refresh (when plaid was first released), but after ~6 months they added the normal horn back.

Show HN: Attempt – A CLI for retrying fallible commands
by maxbond | 2025-09-09 01:37:28+00:00
Hi HN,

Here's a tool I wrote for retrying fallible commands. Nothing groundbreaking here, this is a tool that's been made many times (and several have been submitted to Show HN). Though this one does have a more comprehensive feature set than most. I hope one or two people will find it useful.

I wrote `attempt` for two reasons:

- To have a more featureful alternative to `wait-for-it.sh` for use in Docker Compose. Specifically to apply migration scripts to a database that may not be up yet. I wanted to be able to inspect the error messages from my migration tool & retry on connection errors.

- To test a hypothesis I had that a good way to make a CLI was to copy the API of a good library (in this case, `tenacity`). I want to write a blog post at some point to discuss this at length, but the tl;dr is that I believe it was a success.

Here are some usage examples: https://maxbondabe.github.io/attempt/usage.html

There may not be much to discuss for such a small tool, but I am open to all feedback and am happy to answer any questions.

Cheers,

Max

Yeah, because BYD and other chinese makers are locked out.

Semi-solid state is coming for Tesla's lunch.

"Tesla has image problem." You mean the multiple nazi salutes? The "don't apologize to your past" to the AfD? Being high on something on national television? Unhinged posts on twitter? Kekius Maximus?

EVs are luxury products. You can get 90% of electification with a 50-mile-range PHEV and mitigate the charging infrastructure problem. I have a used Tesla and a PHEV, and if my PHEV only had 50 instead of the paltry 20 mile range, 100% of my daily trips would be fully electrified.

As for further examples of Musk's incompetence, there should be three different badges: Tesla, an ultra-high luxury brand that focuses on traditional cabin comfort, and a low end mass brand. They should have a minivan, station wagon, an actual large SUV, a subcompact city car, a real pickup truck, a work van, and where is the goddamn semi?

Tesla should have bought a struggling auto company for manufacturing, design, and suppliers, and used that for the low-end badge and for PHEVs. Nissan would have been perfect I would think.

Tesla should at this point have joint ventures with huge numbers of electrification avenues: construction equipment, prosumer lawn mowers, "side by sides", golf carts, ATVs, jet skis, boats, if it has an ICE motor, Tesla should be expanding into it with a good name brand.

Of course Tesla solar is moribund, the solar roof is nowhere.

And if anyone claims again that grid storage will deliver some massive sales to Tesla: any success is temporary. Grid will be won by sodium ion and other grid-specific storage chemistries that cylindrical cell manufacture won't be able to compete with.

And yet another point: Tesla's cylindrical cells were an advantage ... five years ago. It's not anymore. Sodium Ion, LFP, semi-solid state, sulfur chems, all will probably be pouch. Cylindrical is basically legacy manufacturing tech.

Musk's cozying up and inevitable fallout with Trump definitely put the EV credits in crosshairs. Probably wouldn't have survived the era of insanity, but that gravy train (1/3 of tesla's profits ... at least) is over.

Finally, let's not forget the total disaster that the dry-cathode 4680 battery cell is. Basically still vaporware, and the Chinese manufacturers have better tech already in manufacture.

AND YET, I'm sure the stock will go up based on the bad news.

Lots of interesting history here, but most relevant was that regulatory and process changes starting in the 80's made it increasingly expensive to build reactors. As a result, reactor construction companies (notably Westinghouse) went bankrupt and no entity was willing to take financial risk to build new reactors. Western Europe is a different story, where political parties aggressively shutdown healthy nuclear plants and passed laws preventing new nuclear.

Much of this regulation and process overhead is now being rolled back in the US (by both political parties) and Europe is slowly coming around to allowing new nuclear. NuScale is one of many next gen companies (I hope they're all successful), but the traditional large reactors are also great and can be built cost effectively.
by fiddlerwoaroof | 2025-09-09 01:38:44+00:00
I think the concept of a “speed limit” is part of the problem. On controlled-access roads, I think it would be better for the posted speed to be advisory and, instead, train drivers to think of driving too slow for your lane as being just as dangerous as speeding because, in a moving group of cars, you want to be as close to 0mph relative to the other cars as is feasible.
by boringg | 2025-09-09 01:38:49+00:00
I think I should correct your statement slightly - its not wrong however we don't have a uranium shortage -- we have more uranium than we could possible use.

We do have a HALEU advanced nuclear fuel supply chain issue. Thats being currently tackled. To your advanced reactor point -- they are also still far away so it is plausible that the supply chain catches up before any of the new reactors get deployed - assuming they make it to the finish line.

I should hope they make it to the finish line - I think we could do well with more nuclear providing our backbone of energy.

> Node.js proper has floated the idea of including chalk into the standard libraries, FWIW.

Oh my word please no! Every time I run into an issue where a dependency suddenly isn’t logging colors like it’s supposed to, it always boils down to chalk trying to do something fancy to handle an edge case that doesn’t actually exist. Just log the dang colors!

Makes a lot of sense. So I am thinking of building an AI-powered Datadog alternative. Why now? is because with AI I can rapidly build integrations to Ruby, Python and other languages. But I'm really low-confidence on this one, because how do I make it reach a lot of people? Is there a need for this? Because I can make it really cheap.

Hello HN! I built Verse as a simple, fast and effortless way to write documents using Markdown and CSS for styling. I was tired of using Word and other Markdown editors bloated with loads of features, and ever since I met Markdown I fell in love with it. Verse (my first open source project) has a built in AI assistant foi when your Markdown skills are a bit faulty, and support LaTeX and Mermaid.

It was built using NextJS 15, Convex, Clerk and UploadThing.

In the coming weeks I want to implement some improvements to the export functionality, and add some agent capabilities to the assistant, as well as an assistant to help with the CSS styling for the elements.

To read some more about it check out my blog post (blog.p4cs.com.br) about Verse.

I'm currently looking for early testers or contributors, any help is more than welcome!

So feel free to try Verse out and tell me what you think. Your first $2 of AI requests are on me!

I agree, but I think LLM-based voice input is a lot better. I’m using OpenAI’s realtime API for my Apple Watch app, and it does wonders, even editing can be as simple as “add a heart emoji at the end”, and it just works.

I’m a little confused by these comments about not checking stuff unless you get a notification.

Do you get notified of every article on HN that you read? Or what about YouTube or other content that you consume?

I’ve had email notifications turned off for years, and have no problem checking my email once or twice a day, just to see if there’s anything worth reading. (Spoiler alert: there almost never is.)

Just like HN, and a couple forums that I visit. I’ll check occasionally to see what’s going on.

For all of these things, it’s never anything urgent or time sensitive. Even if I went a couple days without checking, it’d be fine.

If somebody needs to reach me for anything time sensitive (outside of work), there’s SMS (with notifications) or phone (of course, notifications).

I think much of the issue with these comments — and this whole thread, in general — boils down to:

1. People use things outside of SMS and phone for time sensitive things (solution: move time sensitive things to SMS/phone)

2. People overestimate the criticality/time sensitivity of these things sending notifications

I’d rather check my email (or other X app) once or twice a day, if that, and catch up on low priority things, rather than get interrupted 5-10 times a day for these low priority things.

I recommend talking to potential customers. Do they want cheap? Do they want AI? Or do they want a reliable observability platform they don't have to think about because it Just Works. Not rhetorical! I don't know what these customers want, but you should know if you're going to build for them. Go talk to folks and then go make something people want.

> So pick one that does? That's like its top 2 feature

Still doesn’t work 100% of the time, because half of the companies on earth demote their developer time to breaking 1995-level forms. That’s why every popular password manager has a way to fill passwords for other domains, why people learn to use that feature, and why phishers have learned to convince people to use that feature.

WebAuthn prevents phishing. Password managers reduce it. This is the difference between being bulletproof like Superman or a guy in a vest.

Author here. Very surprised to see this on HN years after I stopped!

Also, thanks for the UI critique, points taken! The design decision was to hide nitty gritty detail about the background unless the reader was extra interested, in hopes of making an article with gradual / adjustable depth so readers who aren't as interested can get a tl;dr for each section (I still don't know how a nice UI to do this, although LLMs make the idea more in reach now).

Does the Euro NCAP test for the likelihood of a collision occurring or only what happens if we assume a collision will occur? It's important, because if a class of vehicles is safer under the assumption of a collision but the collisions happen more frequently versus another class of vehicles, then it's pretty easy to imagine numbers such that the second class of vehicle is actually much safer for pedestrians in spite of a worse safety rating.

A standard release process for Linux distro packages is 1) submitting a new revision, 2) having it approved by a repository maintainer, 3) it cooks a while in unstable, 4) then in testing, and finally 5) is released as stable. So there's an approval process, a testing phase, and finally a release. And since it's impossible for people to upload a brand new package into a package repository without this process, typosquatting never happens.

Sadly, programming language package managers have normalized the idea that everyone who uses the package manager should be exposed to every random package and release from random strangers with no moderation. This would be unthinkable for a Linux distribution. (You can of course add 3rd-party Linux package repositories, unstable release branches, etc, which should enforce the same type of rules, but they don't have to)

Linux distros are still vulnerable to supply chain attacks though. It's very rare but it has happened. So regardless of the release process, you need all the other mitigations to secure the supply chain. And once they're set up it's all pretty automatic and easy (I use them all day at work).

It's just experience in most cases. We don't build enough so the management and project structures and experience to do it never get a chance to be efficient.

The right thing to do with something like the Vogtle plant for example would be to keep building them since you've just paid some very expensive costs learning what causes delays, but the knowledge of what gets the plant built - because it was built - is still there and fresh.
by flysand7 | 2025-09-09 01:46:34+00:00
This article, although is trying to provide some arguments as for why package managers are "evil", I found the argumentation pretty weak/non-descriptive. It's good if you have the experiences that confirm a specific point of view, but I think these experiences need to be explained in some more detail, because people reading your article may have similar experiences and therefore would find it hard to agree with your points - just like me.

To give a concrete example, you said that javascript does not have a definition of a "package" in its langauge. But what does that really mean, and why should it lead to package manager managers? Because for me, a person who has worked with javascript just a little bit, I know package.json exists and most of the package managers I've worked with agree on what the contents of this file mean. If we limit our understanding to just npm, yarn and probably bun, we don't see how that causes or contributes to the dependency hell problem (sure it exists, but how?).

You said that Go mitigates the issue of dependency hell to some degree, but this is an interesting thought, give it more exploration! Why should something like Go not have this problem not be not as severe as in Javascript?

I may not remember the details of what you said in the article and I would like to check, but currently I can't access the site because it times-out for me.

I don't believe it -- although ideology makes explanations like that popular with a lot of people.

The cost escalations and bungling were well in progress before the TMI. The NRC streamlined the reactor approval processes in the 1980s by trying to separate the licensing of a standard reactor from the licensing of the site -- nobody took them up on the offer.

In the case of AP1000 builds both Sumner and Vogtle were held up for years because they were waiting for Chinese factories to figure out how to make parts, in some cases they never figured it out and they had to source them elsewhere. Factory modular construction was supposed to prevent bungling at the site but replaced it with bungling at the factory.

In theory the factories got up the learning curve and if somebody ordered another AP1000 it would be different, in practice the AP1000 is a Chinese reactor and the Chinese gave up on it for the Hualong One which there are (oddly enough) two designs for, which goes back to the designs the French were using back when they were building many plants on time and on budget... which is maybe a good thing, but they look pretty quick to move on to the Hualong Two and before they get up the learning curve on that one they'll be switching to the Three...

I'll agree that the Europe hired somebody who thinks like Amory Lovins to design the EPR and really did bungle the politics more than the engineering, but that's not the story in the US.

> Google, Amazon Robotics/Kiva, Hyundai/Boston Dynamics, even Nvidia are ahead of Tesla in AI+robotics.

Optimus seems to be much closer to actually being released as a product than Atlas. After over a decade, Boston Dynamics still hasn't shown anyone a live, unscripted demo of Atlas as far as I can tell (Tesla was showing those with multiple Optimus robots a year ago). And they don't appear to have any plans for actually selling it as a product anytime soon.

I'm skeptical of the humanoid robot market in general, but at the moment Tesla and Unitree appear to be the two companies ate the forefront of it.
Show HN: Tablemd – canvas-based Markdown table editor
by albert-yu | 2025-09-09 01:48:41+00:00
I created a canvas-based Markdown table editor, which provides a novel (I think) editing experience. I'd love for people to try it out, or bookmark it for the next time they want to insert a one-off table into a Markdown-formatted comment. My design goals were 1) frictionless user input and 2) fast startup time.

Some good-to-knows:

- Can be used on mobile

- Table data is saved locally to the browser (nothing is sent to a server)

- I only tested this on a MacBook, so let me know if the trackpad calibration feels off

I remember hearing on one of the podcasts I listened to about the difference between the Apple power cores and efficiency cores.

The power ones have more execution units I think, and are allowed to run faster.

When running the same task, the efficiency ones are just ridiculously more efficient. I wish I had some link to cite.

The extra speed the power units are allowed is enough to tip them way over the line of exponential power usage. I’ve always known each bump in megahertz comes with a big power cost but it was eye-opening.

Future secrecy?

PGP does multirecipients natively, so any restrictions there would be in the XMPP client.

I have actually tried out PGP over XMPP and is was nice once it was set up. Absolutely no state. If the message somehow gets to you it just works. Sucked when the keys expired though:

* https://articles.59.ca/doku.php?id=pgpfan:expire

PGP support on XMPP isn't really that great. Forward secrecy might be a nice addition, even if it was semi-manual. There are compatibility problems between clients for encrypted media. You don't end up with an always encrypted archive like you do with email, but that could be considered an inherent weakness of instant messaging...

Some people believe copyright should be perpetual. Those people are wrong, but we must still fight against that idea.

I blame the widespread adoption of digital communications. What's the saying? A lie gets halfway around the world before the truth can pull its pants up?

Set against other wrapping pollution at scale how bad is this? And, set against the impact on human life of not making masks ubiquitously available, how much worse would it have been to let e.g. 14 million people die? How do we even know the QALYS without decent epidemiology and demography studies?

I applaud a newspaper giving us understanding of the downside costs of things done, but we don't have time machines, and suggesting (as I am sure many will do) this would have been better avoided by not doing masks is contentious.

> Taking into account the total amount of single-use face masks produced during the height of the pandemic, the researchers estimated they led to the release of 128-214kg of bisphenol B into the environment.

Distributed worldwide, as opposed to the product of the massive plastics factories, also distributed worldwide, mostly in low compliance economies...

I think some moral relativism has to come to the conversation. We should deal with the mask waste stream problem. We should also understand it, set against other problems.

I also use WebAuthn where possible but wouldn’t be so cocky. The most likely reason why we haven’t been phished because we haven’t been targeted by a sophisticated attacker.

One side note: most systems make it hard to completely rely on WebAuthn. As long as other options are available, you are likely vulnerable to an attack. It’s often easier than it should be to get a vendor to reset MFA, even for security companies.

The people I see with Model 3 and Y are the ones who came from Camrys and Rav4.

Tesla EVs have the most data to support their reliability (at least the 3/Y), and they are clearly very reliable. Plus it costs just as much as a Rav 4, but has tons more torque. And the software is much better even though it lacks Carplay.

Okay, I reached out to a few who are cursing DataDog, but also are not fully committed to buying what I'm building. How do I reach out to more people? I mean, it's like I KNOW there is some way here. Because they are not like "I'm happy with DataDog", but it's also not like "We're ready to abandon it for yours". I talked to ones paying like $40k/mo and $80k/mo(DHH).

Yep. I remember being driven around roads like this with a friend with a high performance car who knew what he was doing, so could go what seemed like a terrifyingly high speed to me, but was perfectly safe for him. Then we hit some other cars going slower and he just followed at the same speed, infinitely patient for someone with a thirst for speed. Just completely happy to adjust to the appropriate speed for the situation.
