> It does feel like the reality and perception of AI hasn't converged yet

I learned a word cruising Reddit the other day that summarizes that issue quite well - "liminal". At the time, it was in the context of malls, and the collapse of American storefront consumerism, yet the issues are similar:

"relating to the transitional stage of a process", or "the quality of ambiguity or disorientation that occurs in the middle stage"

> general sense ..., but we don't really know ... the gap between perception and reality will close and labor markets will tighten up

We're stuck in that in-between land where your 2) seems like it's often the response to most suggestions. We'll, we don't really want to take a risk ... cause tomorrow AI may make that choice irrelevant. We don't really want to invest ... cause tomorrow AI may make our investment worthless. We don't really want to hire more people ... cause tomorrow AI may do their jobs easily. And there's always that number 3) sensation somewhere "your team can do more, you're just not leveraging tools enough".

> power is continuous and free via solar array

It’s is on earth as well using solar and batteries. What is likely to get cheaper faster? Solar and batteries? Or lifting datacenters to space? The world is almost at the point of deploying 1TW/year of solar, and batteries are catching up. No space required. There aren't a lot of VC investment opportunities speeding the rate of solar and battery deployments though.

Short-term versus long-term gains. Businesses have the short term covered, but they're rarely going in on high-risk/low-reward (monetarily) research.

So supply and demand can get stuck at these local maxima. Central planning can think longer term. Maybe it doesn't pay off, but sometimes it does. And when it does, it can shake us free of that maximum.

This works, and is why Bell Labs and its peers existed. For reasons I don't fully understand, they stopped doing this, largely. Maybe because it's difficult to quantify those long-term gains.

Finally, those scientists get to choose where they are employed. So if the private sector wants them to do this work, they can hire them.

It’s almost mental illness. I know a family where they filter their water to remove the “chemicals” but eat peach pits for the cyanide compounds that supposedly have health effects.

The common theme is to reject the maximally accepted wisdom in favour of the least accepted. The greater the difference the better.

There is a type of comfort gained by discovering “secret knowledge” while avoiding “the trap everyone else fell into”.

This is definitely a problem we want to work on fixing quickly. We're currently planning an MCP tool that can traverse the graph and decide for itself at each step where to go to next. As opposed to having to generate actual text written queries.

I mentioned in another comment that you can provide a grammar with constrained decoding to force the LLM to generate tokens that comply with the grammar. This ensures that only valid syntactic constructs are produced.

> No, not everyone has a fking iPhone and iMessage.

I don't think iMessage solves the problem of receiving an SMS from your bank where your SIM card is inactive or disabled due to roaming costs.

A VOIP number like Google Voice can solve that problem, but some services that do SMS-based verification reject phone numbers that a database says are VOIP.

I've heard so many "The future of personal computing" statements that haven't come true, so I don't take much stock in them.

I remember when everyone thought we were going to throw out our desktops and do all our work on phones and tablets! (Someone who kept insisting on this finally admitted that they couldn't do a spreadsheet on a phone or tablet.)

> Given that all the compute and all the data is on the cloud, there is little point in making ways for users to do clever interconnect things with their local devices.

IMO, it's a pain-in-the-ass to manage multiple devices, so IMO, it's much easier to just plug my phone into a clamshell and have all my apps show up there.

I did Linux for a bit, but I was really impressed with Windows 10 once I disabled all the junk. Good window management, WSL is fantastic, I really like a few windows-specific utilities, and programs. I like having the Adobe suite + a nix env.

That being said, Windows 11 is making me consider jumping back to Linux, along with me being increasingly annoyed by Adobe.

The Clever Dripper is indeed a really neat invention. One of the old school specialty coffee guys in my city did recommend it. I have yet to move away from my french press though. I don't mind the little bit of extra effort of the french press.

> I ended up turning that process into its own product: https://sparkflow.ai/

That implies that the product is ready, which it does not seem to be? The product does seem interesting, what do you do to differentiate yourself from different offerings that do basically the same? E.g. you mention Discord on the website - are you finding all the relevant discord channels for me, or do I have to join them myself, and you just monitor my account?

In Li Haoyi's recent talk he shows how incredibly fast Java compiler is.

Also demonstrates how much overhead comes from Maven and Gradle.

If Java build feels sluggish, know that first 50s is lost due to maven.

Mill still has rough edges. The project is evolving fast and things change, but it is a great tool.

The BSP support in IDEs is IMO still work in progress (not related to Mill itself) so for JVM languages, Maven and Gradle still have a leg up.

Look at the ultra-compact form factor minipcs from e.g. beelink and gmktec. It's pretty much what you describe, and is an actual computer that you can run real operating systems like Linux on. The form factor is roughly 4" x 4" x 1.5", so fits in a pocket. On the low end, you can get an N150 with 8GB DDR4 for ~$125 on Amazon, which is still monstrously powerful for productive desktop use.

Something like a Steam Deck or RoG Ally could also fit the bill. Gaming handhelds seem to be turning into "phones but if they didn't suck" (i.e. didn't run Android/iOS).
Ask HN: Economists, what's your opinion on US tariffs?
by pinkmuffinere | 2025-05-13 22:21:50+00:00
Everyone and their cousin has an opinion on the tariffs, but I fear that most of what I hear is very partisan, or focuses on details aside from the meat of the actual tariffs (eg, math errors, details of rollout, inconsistent communication, etc). I'm interested to hear an analysis of the impact from the 'raw' tariffs themselves, from people that have some credentials in this space (ie, not just armchair experts). To give some specific topics of interest:

1. I've heard the argument that tariffs will incentivize manufacturing to return to the US. To what degree is this true? Are there alternative methods that achieve similar things?

2. This article (https://www.economicforces.xyz/p/is-dollar-dominance-good-for-the) seems to claim that increased tariffs will reduce trade deficit, in turn reducing financial deficit, which avoids some issues of a Triffin Dilemma (https://en.wikipedia.org/wiki/Triffin_dilemma). To what degree is this true? Are there alternative methods to achieve a similar thing?

3. Are there other legitimate arguments for / against the tariffs that I've missed?

> A OnePlus Android phone is considered an inferior good; an iPhone (or a Samsung Galaxy Android phone) is considered superior. Both are of excellent quality

No, the inferior good is a device with 2GB RAM, a poor quality battery, easy to crack screen, a poor camera. poor RF design and thus less stable connectivity, and poor mechanical assembly. But it has its market segment because it costs like 15% of the cost of an iPhone. Some people just cannot afford the expensive high-quality goods at all. Some people, slightly better-off, sometimes don't see the point to "overpay" because they are used to the bottom-tier functionality and can't imagine how much higher quality may be materially beneficial in comparison.

In other words, many people have low expectations, and low resources to match. It is a large market to address once a product-market fit was demonstrated in the high-end segment.

It is not about one ruling them all. But people will simply coalesce around one language and communities of the remaining languages will simply dwindle. They will all still exist but there is a reason why only few languages are mainstream. And the three I have mentioned will be essentially competing in the same playfield. Unlike Rust, JS or Go, for example, as they already have their niches. All of the three are here to compete for the place in the low-level language tier list.

There are a lot of people who get confused using the SMS code they received, let alone setting up passkeys, or TOTP and backing up their codes, and so on. The systems are designed for those people, not you. Even offering passkeys or TOTP as an option is a customer support liability, that's another thing agents need to support when someone nontechnical inevitably enabled this on accident or has a family member set it up for them.

> Think of the person from your grade school classes who had the most difficulty at everything. The U.S. expects banks to service people much, much less intelligent than them. Some customers do not understand why a $45 charge and a $32 charge would overdraw an account with $70 in it. [...] This customer calls the bank much more frequently than you do.

Partly because they're working with a monolith that I imagine is difficult to iterate on and it's written in Java. We've had the benefit of working on this in Rust which lets us get really nitty and gritty with different optimisations.

My friend who I worked on this with is putting together a technical blog on those graph optimisations so I'll link it here when he's done

My 2 cents. It was light on detail. Not a big enough word count to hit all the recruiter keywords and nothing to back up the claims made.

Obviously a resume can be too long, but i think you need some (well chosen) technical specifics on paper. Intro and current role should be most of the first page, everything else on page two. Two pages is fine.

It's Windows. I'm on Linux 99% of the time and it's significantly more responsive on hardware from 2014 than Windows is on a high end desktop from 2023. I'm not being dramatic.

(Yes, I've tried all combinations of software to hardware and accounted for all known factors, it's not caused by viruses or antiviruses).

XP was the last really responsive Microsoft OS, it went downhill from then and never recovered.

Also, (if it makes any difference): I've had hacks happen before where the method used was to instantly spike the processor's heat to force an emergency shut-off (couldn't find any indications of sudden spikes in application memory/processor usage that would have explained this).

But this time the laptop temperature was perfectly normal and there was no indication of sudden heat spikes.

Most of my awareness of doge comes from browsing the resources they’ve released or watching small commentators do the same. I don’t particularly like or trust corporate media as a rule. My top complaints would be

1 - a lack of transparency. They are very public about the small number of cuts that they can make look good to their base while obscuring/not elucidating a clear, extensive list of their actions. It’s not easy to examine the details of cut programs beyond short descriptions of dubious accuracy.

2 - clear political bias. The cuts/“fraud” they do publicize are frequently just things which appear, on their surface, to be ideologically liberal or left, rather than examples of clear waste or fraud. I say surface level appearance because the details of the cut are rarely more than a single sentence description and a monetary amount.

3 - security concerns. Doge isn’t careful enough/lacks the oversight to be handling Americans’ sensitive records. Their approach is very deliberately to behave more like a small startup, but they neglect security far too much as a consequence.

I think a department of government efficiency is a good idea, but I think doge pretends to be such a thing in order to cut government programs for ideological reasons without having to go through the legislature.

> heavy anti-virus or corporate security scanning that's slowing your computer down more than you expect.

Ugh, I personally witnessed this. I would wait to take my break until I knew the unavoidable, unkillable AV scans had started and would peg my CPU at 100%. I wonder how many human and energy resources are wasted checking for non-existant viruses on corp hardware.

> Radiative cooling is the most basic/common cooling solution on the ground

Thats tricky. I know the heat exchange components are called radiators but most of the heat they give off is by convection not radiation. (At least here on the ground.) I heard 80%-20% rule of thumb.

But you are right in the broad strokes. Cooling is not easier in space. Mostly because you have no convective heat transfer.

Warning: this is an oversimplification.

Performance optimization and being able to "plug in" to the data ecosystem that Apache Arrow exists in.

OpenTelemetry is pretty great for a lot of uses, but the protocol over the wire is too chunky for some applications where. From last year's post on the topic[0]:

> In a side-by-side comparison between OpenTelemetry Protocol (“OTLP”) and OpenTelemetry Protocol with Apache Arrow for similarly configured traces pipelines, we observe 30% improvement in compression. Although this study specifically focused on traces data, we have observed results for logs and metrics signals in production settings too, where OTel-Arrow users can expect 50% to 70% improvement relative to OTLP for similar pipeline configurations.

For your average set of apps and services running in a k8s cluster somewhere in the cloud, this is just a nice-to-have, but size on wire is a problem for a lot of systems out there today, and they are precluded from adopting OpenTelemetry until that's solved.

Reading the paper this sounds like space Theranos. If they start producing results then I'd double check to make sure it's not just calculated on regular data centres and that they're just pretending its from their space stations.

Aside from the technical concerns already raised in other comments, I'm also not sure we really want all this private for-profit usage of earth's orbit. The orbital environment is already somewhat congested and people have already been raising concerns about it. There is the potential for it all to spectacularly blow up in our faces and become so polluted that we won't be able to do many launches at all.

They had Linux on DeX in 2018, killed in 2019. It was a partnership with Canonical

https://9to5google.com/2018/11/09/samsung-linux-on-dex-andro...

It was the Ubuntu 16.04 desktop running in a LXD container. It crashed when the tablet went in out of memory, so I had to be careful with what I was running.

Are you seriously replying and avoiding everything we both said? I'll simplify it for you:

Writing dramatically fast software that is 1,000x or even 10,000 times faster than a scripting language takes basically zero effort once you know how to do it and these assembly optimization are a myth that you would have already shown me if you could.

> I hope they'll also allow the phone's screen to be used like a trackpad. It wouldn't be ideal, but there's no reason the touchscreen can't be a fully featured input device.

I might have misunderstood but do you mean as an input device attached to your desktop computer? Kdeconnect has made that available for quite some time out of the box. (Although it's been a long time since I used it and when I tested it just now apparently I've somehow managed to break the input processing half of the software on my desktop in the interim.)
by echoangle | 2025-05-13 22:29:27+00:00
I’m still not sure how people can believe this, this makes zero sense to me.

There is no easy passive cooling in space, getting rid of heat is a major problem. And you need more redundancy because the radiation will crash your computers. And launch is very expensive of course.

And the whole presentation is completely ludicrous. Look at table 1 in the linked PDF and tell me you’re serious. There is no additional cost when sending a datacenter to space except launch cost and shielding? Building a server farm on earth is the same price as building a satellite you can launch on a rocket as long as you use the same computers?

“Zero effort once you know how to do it” is another way of saying “time and effort.”

Congratulations you’ve discovered the value of abstractions!

I mean, you’re the one who started this off with the insane claim that there’s no tradeoff, then claimed there are no optimizations available below C++ (i.e. C++ is the absolute most optimized code a person can write). Not my fault you stake out indefensible positions.

99.999 may be an ass-pull of a figure, but I was thinking more in terms of having whole datacentres screaming along doing crypto, billions of cat videos, Big Data on "this guy bought a dishwasher, give him more dishwasher adverts", spinning up a whole virtual server to compile a million line codebase on every change, and AI services for pictures of a chipmunk wearing sunglasses. There's a good chunk of computation that we as a society could just go without. I know of embedded systems that run at hundreds of MHz and could replaced by no CPU at all and still fulfill the main task to some extent. Because early models indeed used no CPU. Many fewer functions, but they still fundamentally worked.

Many things we now take for granted would indeed be impossible. I suppose the good news is that in some electropunk timeline where everyone had to use tubes, your TLS connection might not be practical, but the NSA datacentre would be even less practical. On the other hand, there'd be huge pressure on efficiency in code and hardware use. Just before transistorisation, amazing things were done with tubes or electromechanically, and if that had been at the forefront of research for the last 70 years, who knows what the state of the at would look like. Strowger switches would look like Duplo.

Probably there would still be a lot of physical paperwork, though!

But this is explicitly the opposite of how the language is designed to be used, because that's the whole point of RAII.

Says who? If they all have the same lifetime multiple allocations can be combined into one allocation and deallocation. I've done it before, it makes perfect sense, although I would say it is a somewhat niche optimization.

You've got the right idea. The "poem" ("any style of life / is prim...") is encoded as a DNA sequence. This DNA codes for a protein, whose amino acids can be read as English text as well ("the faery is rosy / of glow..."), and which causes the bacterium to glow red. Watts mentions this work in his book Echopraxia as follows:

"The sequence spells a message and codes for a protein. The protein fluoresces and contains a response. It’s not contamination or lateral transfer. It’s a poem."

There's a more verbose explanation in this interview of Bök:

Or we could build a large vacuum chamber here on Earth and put a data center in it, if the goal is to make cooling as difficult as possible. "My data center is too hot! It's burning me!" "Put it in a giant thermos, then you won't feel it anymore."

> They also claim that they can "dramatically increase" heat dissipation with heat pumps.

Right, great idea. Start with the heat where you don't want it -- in the chip -- and pump it out to where it can't go anywhere. Then you can recirculate the medium back and have slightly older heat that you can mix with the new heat! It'll be a heat party!

It's just like a terrestrial heat pump, where you pump the heat out to where you have a huge environmental sink to transfer the heat to. In space, you have something like a hundred thousand hydrogen atoms per cubic meter to take up the heat. A HUNDRED THOUSAND! That's a bigly number, it must work out. We can always make those atoms go really, really fast!

Did an AI invent this whole scheme?

This whole thread is going to motte & bailey between the various forms of US gov ID. Between the union of {SSN, birth cert, driver's license (or ID in lieu thereof)}, it seems to be there's the equivalent of a federal ID. Just, like everything else we do, a terrible incomprehensible mess to Europeans.

My employer requires an SSN when I start a job. TSA keeps alleging they're going to require Real ID any day now. Voting, if I have my jurisdiction's requirements right, requires an SSN, though most people will experience that in the form of driver's license, since getting a license is usually automatic voter registration where I've lived.
