I agree with this analysis; it would be hard for American scientists with spouses and children to relocate. However, there’s another thing to consider: the amount of researchers from grad students all the way to tenured professors and senior industry researchers who are not American citizens who moved to America for their careers.

The following is anecdotal and I don’t have any statistics. When I was a PhD student at UC Santa Cruz, roughly half of my classmates were foreigners, many from mainland China and India, but also from Iran, South Korea, Greece, Uruguay, and Mexico, to name a few. My first advisor was a German who became a naturalized American citizen, and while roughly half of my professors were native-born Americans, I also had professors from China, Ireland, Greece, Singapore, and Argentina. During my time in industry in Silicon Valley as a researcher, I’ve worked with many people who grew up abroad and moved to the United States for grad school.

The biggest issue I see with a brain drain in America isn’t necessarily Americans going abroad, since it would be a major sacrifice giving up family and friends to move to a place with an unfamiliar language and culture. The problem I see is when immigrants to America who have already made those sacrifices end up leaving America, either to return to their countries of origin or to different countries. If a significant number of immigrant scientists leave America, this will be a tremendous blow to American science, and this may also be a boon to countries that are willing and able to hire these talented people.

China, for example, has the money to fund science at levels competitive with the United States. I don’t foresee a lot of Americans moving to China, partly due to the language barrier, and also partly due to China’s political system. However, what if Chinese researchers in the United States return to China en masse? This is not good for us, though it would be great for China.

These are scary times in America.

The IOT and embedded space is simultaneously obsessed with IP protection, fuse protecting code etc, and incapable of managing the life cycle of secrets. I worked at one company that actually did it well on-device, but neglected they had to ship their testing setup overseas including certain keys. So even if you couldn't break in to the device you could 'acquire' one of the testing devices and have at it

Don't think unions will happen in the tech industry because the workers are too selfish to have solidarity with one another. Just look at how hiring is done compared to the job duties required.

I do think implementing workplace democracy is much more likely, and can be legislated into law too. While tech workers will argue about unions, I feel like most of them wouldn't argue about getting the chance to vote for their boss.

Do you have experience with unions yourself?

> IIUC the actual device that does the kaboom remained with its original design and applying voltage will be able to trigger it

That is not my understanding. My understanding is that the proper implosion requires very precise timing of signals for each shaped charge element otherwise the implosion ends up being lopsided and the nuke fizzles instead of exploding. These timings depend not just on the shape of the charges, but also on the relative wire lengths from the detonator to the explosives. (In theory these wire lengths can be unique for each warhead, thus making the timings for each warhead unique). The detonation circuit is not just comparing the code with an expected one, but using it to create the right signal timings. In other words the right code plus the information in the electronics together gives the timings for the signals with which they propagate through the different length of wires such that they form the right implosion.

To reverse engineer this you need to figure out when each explosive element needs to be triggered to form the explosion. Then you need to figure out when the signals need to leave the electronics such that it travels through the wiring looms just right to create the desired explosive pattern. And then you need to figure out what code you need to supply the electronics so it produces this desired electronic timing to achieve the above.

That is three wickedly hard challenge. And you will only know if your people pulled each of them off corectly, when you try to detonate the warhead.

> won't stop people with unrestricted access

That is true. But it is not like all they would need to do is to apply voltage on a single line, like some crazy hot-wiring car tief. Their best and easiest bet is to dissasemble the warhead and use the fissile material from it inside of an implosion device of their own design.

The echo chambers of social media donthat to us. The fewer interactions we have with those holding opposing viewpoints the more difficult it becomes to rationalize their views as anything but malicious. In that spirit can you explain what you mean? From my perspective it looks like the attack on academia that always occurs during populist coups. I don't doubt that biased science is done out pf greed, but I would need exceptional evidence that it was the norm, or even common enough to warrant this. Healthcare workers including doctors are leaving now too. This all mirrors what was seen in Hungary andany places before that.

Sure, this is one of the reason we develop the framework of json/yaml conf and the embedded http server, with this framework, we discover several RocksDB bugs by this framework(we have contributed 100+ PRs and 60+ issues for RocksDB).

With embedded http server, all DB configurations and status are visually displayed, for example: the compaction progress, the SST file list with the compacting files are highlighted -- with different colors for different compaction jobs, different icons for different compaction types(https://github.com/topling/sideplugin-wiki-en/wiki/Compactio...)

Sounds like the kind of thing that, if the people with nightmares know this, it could give them more nightmares.

For the last maybe 20 years, I rarely even dream, or rarely remember my dreams. But I'm also fairly accepting of, and reactive to, the reality with which I'm presented, no matter how dark the timeline seems to be. I don't know if these things are correlated though.

How do you type Cmd+C versus Ctrl+C?

I find the Windows version more ergonomic because the keys are farther apart, so I press Ctrl with my left hand and C with the right one. Meanwhile, on MacOS, Cmd and C are closer to one another, so I end up pressing them with the thumb and index finger of the left hand only. I believe that movement is not as ergonomic, although more intuitive.

Building agents has been fun for me, but it's clear that there are serious problems with "context engineering" that must be overcome with new ideas. In particular, no matter how big the context window size is increased - one must curate what the agent sees: agents don't have very effective filters on what is relevant to supercharge them on tasks, and so (a) you must leave *.md files strewn about to help guide them and (b) you must put them into roles. The *.md system is essentially a rudimentary memory system, but it could get be made significantly more robust, and could involve e.g. constructing programs and models (in natural language) on the fly, guided by interactions with the user.

What Claude Code has taught me is that steering an agent via a test suite is an extremely powerful reinforcement mechanism (the feedback loop leads to success, most of the time) -- and I'm hopeful that new thinking will extend this into the other "soft skills" that an agent needs to become an increasingly effective collaborator.

I've been unemployed for months. In the last couple of weeks, I've been rejected for jobs as a pool cleaner, shelf stocker, and a state job requiring me to check multiple email accounts and watch security cameras. I've also recently been rejected as an overnight courier and software tester.

Whatever you imagine the job market to be like, I assure you it's worse.

This has definitely been my feeling too as a fresh postdoc. For a while it has been feeling more and more like the US isn't worth the effort and stress.

Sure, I make more money here, but is it worth dealing with nonsensical immigration policies, haphazard funding cuts, crumbling infrastructure, completely random rulemaking, and demoralized colleagues facing severe and nonsensical budget cuts when various other countries with a good standard of living and competitive research labs make immigration very easy for skilled people like scientists?

It isn't specifically a Trump thing, but he's certainly proving to be the straw that broke the camel's back, and it's likely I'll go elsewhere once my postdoc appointment ends.

I can imagine that the decision is even easier for people from countries like China. Why deal with the stress of the government suddenly deciding that you aren't allowed to work at your institution anymore regardless of track record or background, (many chinese colleagues have been worried about the proposed legislation and it comes up often), when you can work at a similarly cutting edge institution back home? You just have to determine if the US being less authoritarian on certain things is valuable enough to put up with the awful treatment through the long immigration process.

Apple rescued itself from bankruptcy with the iPod. When mobile phones began to gain storage for MP3s and internet access, Apple saw the writing on the wall for their cash cow. They pushed a multitouch acquisition from room-scale projection to another level for handheld devices, and then married that with its supply chain breakthroughs at the time. Now it sees the writing on the wall for iPhone and the relevancy of all the halo products and services once more ambient on-person computing becomes common.

Oh it's certainly great having a camera in your phone. But it feels artificially crippled by all this fiddly software and tapping and swiping and reacting to the many screens you have to navigate through to get there. Great to hear newer phones have a hardware camera button, even if it does just open the app, that's still a big step forward.
Show HN: I created a privacy respecting ad blocker for apps
by bentocorp | 2025-07-03 01:04:52+00:00
Hey HN, I’ve been working on developing my ad blocker for the last number of years and am proud to share that I have now released a new feature that blocks ads directly in apps — not just in a web browser.

What makes this app ad blocker feature special?

- All ad blocking is done directly on device,

- Using a fast, efficient Swift-based architecture (based upon Swift-NIO)

- Follows a strict ZERO data collection and logging policy

- Blocks ads in all apps on iPhones, iPads and Macs

It works as a local VPN proxy, so it filters all of your traffic locally without going through any third-party servers. The app ad blocker works across News apps, Social media, Games and even browsers like Chrome and Firefox.

After using ad blocking in Safari for a long time, it is eye-opening how many ads and trackers are also embedded in apps themselves. The app is available via the App Store, with a 30 day free trial, before an annual subscription is required.

I know there are many other ad blockers available, but I hope the combination of performance, efficiency and respect for privacy will mean that this particular feature is a valuable option.

It also took a LOT of work to get this working seamlessly within the App Store and iOS / macOS limitations, so am glad the app has been able to finally be released into the world.

Full details on the feature are in the release post:

I'm not yet convinced (though I remain open to the idea) that AI agents are going to be a widely adopted pattern in the way people on LinkedIn suggest.

The way I use AI today is by keeping a pretty tight leash on it, a la Claude Code and Cursor. Not because the models aren't good enough, but because I like to weigh in frequently to provide taste and direction. Giving the AI more agency isn't necessarily desirable, because I want to provide that taste.

Maybe that'll change as I do more and new ergonomics reveal themselves, but right now I don't really want AI that's too agentic. Otherwise, I kind of lose connection to it.

You do have a choice, because the state/police/military aren't an opaque non-human monolith. They are made up of people who DID make the choice to take up that burden, for any given reason, it doesn't have to be an act of selflessness or duty or love for people or country. It just requires some subset of your population being morally at ease with that.

Being able to endorse extreme pacifism long enough to have your belief turn into a large group with many followers is a privilege of being a subgroup in a society where someone else isn't bound by that particular moral outlook. That's all I meant by offloading the burden. You can oppose the violence of secular society, as you put it, while also accepting that that opposition would only ever have worked at any point in history if only a part of your population agreed with you.

That kinda works in the abstract, but it's pretty risky for any individual house. If your house was somehow a representative slice of all US housing, sure maybe it won't drop 35%.

But if you owned a house in Detroit from 2003-2010 it might have dropped 70-80%. Or, more on point for many on HN, if you own a house in the Bay Area worth $2-$3M with 25% equity, and the tech job market collapses, then you might get completely wiped out.

I use live captions for this a lot and find that it's pretty accurate. It's helpful if someone says something that I don't catch and I can just scroll up the captions to make sure I understand.

Also helps if someone tries to interrupts and the live caption can notate who was the breaker so I can call on them without a dumb-sounding "uh who was that?"

Well said. A few days ago I made a response to a comment in a thread, where I laid out a list of some aspects of American Culture [1].

This assumption is a pretty Western view, in that you assume that SV/USA still has technological primacy. I believe this to be generally true, but leadership has no incentive or reason it should. And if I'm being frank, there may be some bias here because it seems like companies with indian CEOs are offshoring at a much faster rate than non indian CEOs (e.g. Google vs Netflix). And non core roles could effectively be perceived to make up the majority of the company. So some cultural fondness for India plus a somewhat low view of the bulk of employees could result in most jobs being offshored.

It feels as if these issues are only going to increase in parallel with the increasing rhetoric from the US about "other-ness" being "bad", and the co-dependence between the current administration and the US tech sector.

This is only one example, and sensitive and possibly poorly chosen for the sensitivity of the topic (or maybe that makes it well chosen), but it was recent: https://mondoweiss.net/2025/07/metas-banning-of-two-anti-zio...

Getting on the wrong side of a cause that is randomly chosen as important by the platform can be greatly damaging. It's easy to say what I regularly read on HN "you shouldn't have your income depend on the whims of a third party" despite it being true. The non-tech folks, which are in the great majority, don't know this.

It doesn't really help that they don't want to know either. But it is the responsibility of us tech-folks to keep letting them know that what they may consider "constant" may well be "variable" sooner rather than later.
by thimabi | 2025-07-03 01:11:06+00:00
Do you think that, over time, knowing how the models behave, simply providing more/better context and instructions can fill this gap of wanting to provide taste and direction to the models’ outputs and actions?

My experience is that, for many workflows, well-done “prompt engineering” is more than enough to make AI models behave more like we’d like without constantly needing us to weight in.

3x more than the Marine Corps, for those at home keeping score.

A military branch (either de facto or de jure) that exists for the majority purpose to directly target, round up, and imprison or deport individuals on U.S. soil - especially with a proven record of limiting due process - should have NEVER happened. I cannot stress enough, we're a few bad days - and more and more likely 1 executive action away - from at-scale "Tree of Liberty" stuff.

I didn't say that. You've been posting it everywhere and called it a "better source" that we should all read. Calling it "your source" is a reasonable shorthand.

> How you get from that to "we don't know if they'll ever publish it again!" is beyond me.

I didn't say that either. I only pasted a direct quote from an article you urged everyone to read. How you get from that to what you're saying is beyond me.
Super Simple "Hallucination Traps" to detect interview cheaters
by EliotHerbst | 2025-07-03 01:13:22+00:00
After testing out Cluely with my team, we suspect that the easiest way to detect interview cheaters is to set simple "hallucination traps" where you ask a question that sounds plausible, but any knowledgeable person would instantly identify as a joke, fake, or just simply say they don't know. Vibe coded a simple app demonstrating the concept - https://beatcluely.com/

Here are some examples of this class of prompts which currently work on Cluely and even cause strong models like o4-mini-high to hallucinate, even when they can search the web:

If 99% of people aren't on the list, and 1% are, if your check is super fast but makes 1% false positives, you still end up having to only do a full check on 2%. Which could be a huge huge huge win computationally.

Your post is really weird to me, talking about boarding times? You start skeptical of the example & I'm confused how you think this is anything but a fine example. Ultimately there's some service running in the cloud somewhere that needs to have checks run against it. 2.9m people fly a day in the US, and whether the servers doing that work can do it efficiently or whether they do it in a dogsbit bad manner seems like an obvious concern to me? https://www.faa.gov/air_traffic/by_the_numbers

I suspect the actual usage for this is for much broader higher traffic systems. For things that watch sizable chunks of the internet for patterns and traffic. But checking passengers against. I fly lists sounds like a pretty reasonable example use to me, and the criticism seems off base & weird in a number of dimensions that straight up don't make sense.

These comments are creating exactly the feeling that troubled me about in-person engineering meetings and I still can't quite express it. It's like we all know we don't want to discuss this topic and can't help but do so. I get the same feeling whenever I see a bot introduce itself and then someone immediately replies "read stop". It's pretty close to a mixture of regret and disappointment.

Unfortunately the way students and the culture around them require in a university is much more than instruction hours. You need to pqy for all the infrastructure and the amenities that these students except and many will choose based on that. I was talking to a couple of parents during a visit recently and they focused more on what the experience their kids will get at my university. They were mostly not talking about education experience.

And most universities don't have any significant endowment and they don't work like what you think. Most of these are money for specific goal. i.e as rich alumni of CS program I can donate $100m and ask the university to invest them or put them in a bank and then pay grants for CS students. The university is legally bounded to not use the money for anything else. But this will be counted as +$100m endowment money for my university.

Yeah and the infrastructure of economic/political exclusion is initially just used against that "horrible" group X, but eventually expands to the majority of the population. This is because greed is basically an endless hole. They get to threaten the wider population "toe the line or you'll end up like them".

A lot of times the effects are invisible. I doubt everyday Mississippians even think about how slavers stole their future from them. Americans barely ever think about the trillions of dollars that the Iraq war wasted/stole.

It was 18 months of somebody working on it full time plus people being flow out from the manufacturer.

From memory once it was going it still didn't live up to all the hype. It worked about as well as the 30 year old machines next to it and required a minimum wage person (ie me) to operate it (plus a fitter for anything technical).

The company I worked for went out of business 10 years later.

This is the sort of machine I'm talking about (although a lot nicer and more uptodate than the ones I used. Faster cycle time too)
