Seems like China is entering every industry. This week they just launched their attempt to take over the ice cream market in the US. Its amazing to see how much overinflated every product in the US has become, everything from cars, to computers to now even freakin coffee or ice cream.

[0]: https://www.youtube.com/watch?v=Kcae6aiV1vs

Imagine if China has a foothold in every industry. Sure the US can tariff itself but the rest of the world is not really competing in most of those industries and so consumers will be able to see that they dont have to settle for overpriced junk anymore. What will American/European or even other sian companies do? In America most companies have financialized so much that the underlying product that made the company famous have rotten in quality.

I recently was blown away Laifen's P3 Pro electric razor. I always thought I would be a loyal Panasonic customer for life (since I had family work for the company) but here comes this Chinese company from nowhere and they produce such an amazing device at an amazing price. I never thought having a CNC milled pocket razor using some sort of tiny linear motor would be something I would want but now I can't see life without it.

They are doing it to every industry. I always accepted things like 3D printers were gone thanks to Bambu but I now have to consider every industry at risk.

If you don’t understand how to do programming at this level you’re not going to get far with an LLM. They tend to fall down on anything larger than a greenfield todo app.

You can easily write slow code in C and Rust. Get enough branch mispredictions and cache misses and it won’t matter that your program is written in a low level language. Guiding profilers to optimize workloads takes more context than source code alone has. You’ll still need to know how memory is architected and how many cycles instructions take on the platform you’re targeting. And you’ll have to guide the LLM to it. It might be easier and faster to do it yourself.

An LLM can generate the kind of code that has no obvious errors in it. It’s trained on the sloppy code that unreasonable deadlines and hubris produce. Humans are notoriously bad at detecting undefined behaviour, safety, and temporal errors in single programs let alone whole systems. How is an untrained developer who hasn’t been contending with systems programming for the last twenty years supposed to review and verify this code?

You’ll need to get fast at verifying large amounts of code quickly or else pray that the LLM isn’t generating the kinds of exploitable memory bugs that lead to funny machines and RCEs. We already have enough of this code as it is and most teams are trying to be conservative with their tech debt.

I have no doubt that some amount of code will be generated by LLMs in these sorts of languages and systems. Even after the bubble pops and the feudal lords lose their ability to extract rents. But I think most people using them will be more tactical and careful in their approach. At least I hope so.

There are still many good reasons to use a high level language. And if folks want to break into systems programming that’s great! But you have to learn systems programming in order to use an LLM effectively, in my experience. There’s no shortcut.
Show HN: ARM – NPM for AI coding assistant resources

Managing cursor/q/copilot rules and prompts across projects is painful. ARM solves this with:
- Semantic versioning for AI rules/prompts
- Install from Git repos (awesome-cursorrules works out of the box)
- Priority-based layering (team standards > community rules)
- Write once, compile to Cursor/Copilot/Amazon Q
- Manifest + lock files for reproducible environments

Built in Go, GNU GPL v2 licensed. Would love feedback from the community.

Forgive my zooming out but the overton window on this topic is in the wrong place. Airport security is dehumanizing inconvenient and unacceptable. I’d only use planes in an emergency. The living memory of what air travel is supposed to be is just gone with the sands of time. I don’t accept the shit economy version starting #1 with the cattle screening.

My one and only experience of dealing with the police in the US was when I was visiting NYC. A tourist was being attacked on the subway because he was taking pictures and since we were still at the platform I jumped out and told 2 officers further down the platform what was going on. I expected them to sprint into action, but they could not have cared less and casually strolled along towards the carriage!

In a similar vain I was the first on the scene of a car crash in the UK, where the driver had exited the vehicle through the window (no seat belt) and was bleeding in the road. When the police turned up they casually and slowly walked up the road towards the scene.

It made me wonder if there was a good reason for this, like to control adrenaline, make better decisions, have time to assess the situation. Or if they were just jaded from seeing it a lot.

Oh I have a plan for this.

Allow it to answer general questions about health, medicine and science.

It can’t practice medicine, it can only be a talking encyclopedia that tells you how the heart works and how certain biomarkers are used. Analyzing your specific case or data is off limits.

And then when the author asks his question, it says it’s not designed to do that.

I am not up-to-date on the bleeding edge but that explanation doesn’t seem correct? The use of x-rays in analytical chemistry is for elemental analysis, not molecular analysis. (There are uses for x-rays in crystallography that but that is unrelated to this application.)

At an elemental level, the materials of a suitcase are more or less identical to an explosive. You won’t easily be able to tell them apart with an x-ray. This is analogous to why x-ray assays of mining ores can’t tell you what the mineral is, only the elements that are in the minerals.

FWIW, I once went through an airport in my travels that took an infrared spectra of everyone’s water! They never said that, I recognized the equipment. I forget where, I was just impressed that the process was scientifically rigorous. That would immediately identify anything weird that was passed off as water.

> Andy Jassy and Mike Hopkins, both of Amazon, were also in attendance, but that is partly explained by the company’s $40 million bid for the rights to film part of the brief period between the election and inauguration. $28 million of that went straight into Melania Trump’s bank account.

Time to cancel Amazon prime. These people don’t care if you get brutally killed in the streets or if your constitutional rights are violated.

Hi HN — we’re shipping a feature in DeepTutor this week: turn a paper into runnable code and export a Jupyter Notebook.

It’s meant for quick reproducibility: implement an equation/method, run a sanity check, and keep everything in a shareable notebook.

I think this is certainly true, except for the "each engineer [bringing] whatever syntax or language" point.

At some stage, I expect that we will know what is the set of "optimal" computer languages for the interface between the programmer and the machine code.

Natural languages can't really capture the lower-level details of a program, but there's (probably) also no need for all N different ways to write a for loop.

You aren't arguing with me in the sense of engaging with what I'm saying. You're just being pompous. Pretty typical for Europeans.

I don't want the world to revolve around me. I'm completely tired of that. I want to be Switzerland. We stayed out of Europe's problems pre-WW1 and we can do it again just fine.

I probably won't reply to your further in this thread, because I expect any further comments from you will be additional fact-free condescension. (If you want me to reply I suggest you start by apologizing.)

Anyways, good luck with Russia.

Very interesting, thanks for the insight into modern uni. It’s been a long time since I was there and struggle to imagine what it must be like now.

It does seem like they’re going the wrong way, repelling tech to keep things easy instead of embracing new tech by updating their teaching methods.

But I also think we’ve collectively fallen flat in figuring out what those methods are.

> therefore an important relief valve

Until it is done to your small business or home, then it is no longer an "important relief valve". The solution to reducing graffiti is multi-part. Here are a few ideas: (1) Pass a state law to restrict the sale of spray paint -- you need a special license to buy it. (2) Pass a local law to reward citizens who provide evidence of taggers (video, photos, etc.). If the city can convict, you are rewarded. Make the reward large enough (1000+ USD?) to be strongly encouraging. (3) Create public spaces where people are allowed to spay paint. This is a little bit like skate parks.

it's not significant watch the full video: https://www.youtube.com/watch?v=YeFzeNAHEhU

this guy was harassing tanks as they were leaving. he harasses and climbs on the tank and is unharmed. eventually others drag him away.

you can see the tanks are leaving the square in a wider photo here: https://pc.blogspot.com/2012/06/tank-man.html

it is not clear to me if he is harassing the tanks because he disagreed with them or because he wanted them to go back. it seems no one has interviewed him or the soldier he talked to so we'll never know.

EDIT: I should note that one of US ally Israel's favorite tactics is to run over defenseless Palestinians with tanks and US made bulldozers. Well documented, with gruesome photos that will make you retch at a pink stain that used to be a person. They also ran over Rachel Corrie, a U.S. citizen peace protestor in 2003.

That's really quite interesting. I know the wireless charging uses more power to deliver less power, so there's heat generation due to the loss of power in the transfer (I'm assuming that's how it works).

But, I figured that the battery would heat up more the faster it's being charged, and so wired charging at the same wattage would heat the battery more than wireless charging.

Must be a lot of power->heat transfer loss with wireless charging.

Tel Aviv has allowing this for quite some time (10 years?). I guess they update their security devices as soon as new technology becomes available.

They don't advertise it, I found out by accident, trying to empty my water bottle by drinking when a security person told me to just put it together with the rest of my stuff. I had no idea that was a thing and was pretty confused.

In the short term, you might see better outcomes with pure vibecoding...but in the long term, when you're mentally burnt out, cynical, and losing motivation, that's a bad outcome both in terms of productivity and your own mental health.

We need to find the Goldilocks optimal level of AI assistance that doesn't leave everyone hating their jobs, while still boosting productivity.

I don‘t think that is true at all. There have been numerous hijacked planes since 9/11 including two in the USA just this decade.

https://en.wikipedia.org/wiki/List_of_aircraft_hijackings

Plane hijacking has been on its way out anyway after the turmoil of the 1970s. And that has probably more to do with a) the relative political stability of the post cold war period, and b) a general sense that airplane hijacking isn’t actually that likely to advance your political goals. If you read the list above, you see people hijacking planes all kinds of dumb methods, hardly any of them involves carrying an actual bomb onto the plain.

> In the US, the TSA is just a government jobs program for the lowly skilled or unskilled. It's all security theater.

This matches my experience. I recently flew out of a small airport that flies 2 fairchild metro 23 turboprop planes up to 9 passengers. There were four TSA agents to check the 5 of us that were flying.

This is exactly what I've been screaming about, AI coding assistants are basically playing guess the impact with our production code. The fact that you're exposing actual call graphs and blast radius through MCP tools instead of making Claude hallucinate dependencies is huge from my pov. Installing this now to test with our multi-repo setup. Does the telemetry integration for dead code detection require specific instrumentation? does it hook into existing APM tools?

^ exactly.

And since the user has the original key, it'd have to be voluntary surrender. After you turn your key in, you lose access.

The best part is the whole thing could be reviewable and added to a public immutable ledger, encrypted, to make the whole process, transition, and access transparent for courts later. Wouldn't it be great if more investigations happened that way?

And if you don't trust law enforcement, thats your prerogative, no need to use the feature.

And Apple won't let you add all your "trusted phone numbers" to all those accounts. So, if you are in country A and your country B phone can't receive SMSs, and you get a new device, you can't log into country B account because 2FA via SMS does not work. (And no, you can't just make multiple accounts on a MacBook or other device that supports multiple accounts for non-SMS 2FA; login fails.)

> But a doctor who sees a person come in who isn't complaining about anything in particular, moves around fine, doesn't have risk factors like age or family history, and has good metrics on a blood test is probably going to say they're in fine cardio health regardless of what their wearable says.

This is true of many metrics and even lab results. Good doctors will counsel you and tell you that the lab results are just one metric and one input. The body acclimates to its current conditions over time, and quite often achieves homeostasis.

My grandma was living for years with an SpO2 in the 90-95% range as measured by pulse oximetry, but this was just one metric measured with one method. It doesn't mean her blood oxygen was actually repeatedly dropping, it just meant that her body wasn't particularly suited to pulse oximetry.

> . This reminds me of the chemical swipes done on your bags to detect explosives. Those swipes can only detect a narrow set of explosive chemistries and everyone knows it.

Meanwhile, you get swabbed, the machine produces a false positive, the TSA drone asks you why the machine is showing a positive, you have no fucking idea why, and they just keep swabbing until they get a green light and everyone moves on with life.

If you come in from a country that doesn’t fall under the TSA, you have to clear TSA before getting on a flight that does.

The worst I had was in India, flying to the US. Not only was there the normal airport security (despite having come in on a connecting flight from within India), but when I got to the gate (with only minutes to spare), there was a whole TSA check at the gate itself. Bags x-rayed (again), metal detectors (again), guy with a wand (again), the whole deal. Just getting to the gate, I had to show my papers to at least 6 people; every time I turned down a new hallway. That was my far my worst airport experience.
by chipsrafferty | 2026-01-27 05:49:10+00:00
But also you can fill up a water bottle after security. Wouldn't it be fairly easy to make a pen or similar innocuous item out of sodium, and drop it in a bottle of water to make an explosion?

My point is that security can never be strict enough to catch someone who's truly motivated and funded, without making it impossible to admit people at a reasonable pace, and the current rules don't really help with that except for cutting down on the riff raff terrorists. But maybe those are more common than a trained professional with high tech weapons, I don't know.

This maps to what we've seen building AI at work.

When we started building a voice agent for inbound calls, the models were close but not quite there. We spent months compensating for gaps: latency, barge-in handling, understanding messy phone audio. A lot of that was engineering around model limitations.

Then the models got better. Fast. Latency dropped. Understanding improved. Suddenly the human-in-the-loop wasn't compensating, it was enhancing.

The shift was noticeable. We went from "how do we work around this limitation" to "how do we build the best experience on top of this capability." That's MMF in practice.

The timing question is real though. We started building before MMF fully existed for our use case. Some of that early work was throwaway. Some of it became the foundation. Hard to know in advance which is which.

india is a great market, but:

1. extremely price sensitive; zoho is regarded as expensive

2. 121 major languages in active/business use, with 22 formally recognised by government. These people may understand limited english.

3. 28 unique states plus 8 unique territories.

so in many ways its like expanding across the US, except there are 22 languages as well as 36 state law regimes, plus federal law, and then indian city law, transfer pricing regimes, currency settlement issues... etc.

China is also possible, but still price sensitive and strongly culturally prefers local solutions

This is an interesting point, but I push back a bit. First, "Manhattan" is much larger than most people realise. There is almost no graffiti in the rich neighborhoods (Upper West/East, etc.), but there is plenty of graffitti in the more iffy neighborhoods (East Villiage, ABCs, SOHO, etc.). It pretty much scales with wealth -- richer has less graffiti. Second, specific to this post about San Francisco, there is almost no graffiti in the suburban areas out west (Sunset, Richmond) and wealthy neighborhoods like Russian Hill or The Marina, but loads of graffiti in The Mission, Potrero Hill, and SoMa.

When you don't know much about a topic, probability is higher that your are missing some piece than some entity doing things that make no sense.

I know it's easy to get the impression that's not the case. But when your stop making fun of / belittle such events / persons / decision and be curious instead you start to realize that more often than not you are just missing a piece of information.

The truth oftentimes is just not interesting enough and not clickbait worthy.

Hi Show HN,

I’m really excited to share something I’ve been working on since late November last year.

I’ve always struggled to wake up in the morning. I’d often feel groggy when my alarm first went off, turn it off, and drift back to sleep. Then I tried something different. I recorded myself saying a message about why I should get up, edited it in GarageBand, and turned it into a ringtone for my Apple Clock alarm. It worked. Hearing my own voice remind me of what I needed to accomplish made it much easier to wake up.

But there was a problem. Updating the alarm every day was tedious. I had to record a new voice memo, edit it in GarageBand, export it, and set it as my ringtone. And after a while, I got tired of my own voice. It’s kind of weird hearing yourself first thing in the morning . Around that time, I also started playing around with ElevenLabs voice technology and realized this app would be perfect to put their incredibly realistic voices to use. So I decided to build an app to make this process effortless.

The app is called Wake AI and it is available on iOS and iPadOS. It lets you create talking voice alarms with custom messages. You can choose from a wide range of natural AI voices, making it feel like someone is actually talking to you in the morning. I find it extremely useful because I can change the voice every night based on my mood. Some days I like a Western cowboy to wake me up. Some days, if I feel unmotivated, I choose a sports coach voice. Other days, a girlfriend-like voice helps me start my day.

This project has been a great learning experience so far. I’m new to building mobile apps, and one thing I’ve learned is that great UI doesn’t mean having the most stunning colors or graphics. One of the recent updates I’ve been focusing on is improving the layout of the app so that it is intuitive, easily accessible, and works well for users needing VoiceOver support.

Wake AI is live on the App Store and you can check it out at https://apps.apple.com/us/app/wake-ai-talking-voice-alarm/id....

If you believe Hank Green (https://www.youtube.com/watch?v=325HdQe4WM4), a lot of recycled plastics aren't recycled the way I used to think they were (by shredding them, melting them down, and extruding them into new shapes). Rather, they're chemically decomposed into what's essentially raw feedstock, purified, and then re-synthesized into new polymers.

That's pretty energy intensive, to the point that it may be better to just use new feedstock (which is produced as a byproduct of oil and gas extraction). There are obviously higher-order effects to think about, but for me, plastic recycling isn't an obvious win for the environment.

OP is talking about (mostly) TATP here. It's very easy to make, harder to detect with traditional methods and potent enough to be a problem. It's also hilariously unstable, will absolutely kill you before you achieve terrorism, and if you ask people on the appropriate chemistry subreddits how to make it you'll be ridiculed for days.
