I think this is somewhat reasonable, but with plenty of asterisks / not the "arbitrage" this would imply.

There is still a "real", regulated money-holder in the loop - it's just Bridge (the manager of the cash reserves backing the coin - and licensed money transmitter etc etc). Or in the case of USDC - Circle, the "money-holder" / manager of reserves (also has tons of licensed / is very regulated). And the ETH network (where the coin itself sits) for much of the tech / logistics of making that held-money usable.

In fact - because neither Bridge nor Circle are banks, they can't do the fractional reserve that banks do, and are only allowed to do the 1:1 backed thing, with super regulated entities like BlackRock. "you can lend out the money you earn from selling someNiceCoin to services with higher yields" is strictly not true - they _cannot_ lend the money out, they have to store the money in ways that the end-consumers could do themselves, directly.

In that frame - the "efficiency" for you as a fintech is that instead of having to work with a bank on a "stored value" program, you can just work with Bridge and Circle, whose technological primitives are leaps / bounds ahead of the bank, but more importantly - who are much more flexible to work with than the median "partner bank", because they are not banks.

The whole "partner bank" ecosystem only really even scales because there are API providers like Increase.com / Unit.co etc to wrap them.

Potentially not even so high as that. You often see 2,500 m (8,500 ft) used as the beginning of "high altitude" - at that point some studies have detected cognitive effects from long-term exposure. (10.1007/s11065-004-8159-4) A lot of research is focused more on ~4,000+ meters though due to the existence of the Tibetan Plateau.

Indians in America aren't eligible for an E3 like Australians are.

Furthermore, Indians in America face a 20-80 year permanent residency backlog depending on when they arrived in the US. The majority of Indians nationals in America will eventually return to India as a result.

The US is increasingly viewed as a temporary posting instead of as a naturalization destination becuase of the backlog, and most other Western countries don't provide lucrative offers for the cream of the crop compared to what they can demand in India.

For example, the average new grad salary at IIT Kanpur was around US$30K for the class of 2024 [0], and a mid-career TC of US$60k-70K is realistic for INI grads (as one of the other posters in this thread is an example of).

Most of India's R&D is overwhelmingly generated by alumni of these INIs, and the majority of investment is placed in these programs. These are also the kinds of programs that previously used to represent the bulk of the brain drain 15-20 years ago, but their grads overwhelmingly remain in India unless doing graduate school like a PhD or an MBA (these aren't the kinds of people doing an MSc in Business Analytics at Wollongong in order to get an Australian permanent residency), let alone accepting decades of indentured servitude due to the EB2 processing backlog.

A few issues:

1. The tech revolutions of the past were helped by the winds of global context. There were many factors that propelled those successful technologies on the trajectories. The article seems to ignore the contextual forces completely.

2. There were many failed tech revolutions as well. Success rate was varied from very low to very high. Again the overall context (social, political, economic, global) decides the matters, not technology itself.

3. In overall context, any success is a zero-sum game. You maybe just ignoring what you lost and highlighting your gains as success.

4. A reverse trend might pickup, against technology, globalization, liberalism, energy consumption etc

Neat. If you add some automatic memoization, I'll use it for my next project!

Here's the use case:

expr := ...

rule1 := expr foo expr

rule2 := expr bar

When trying to match rule1 and failing, it is great to have the expr part of it already parsed and ready for trying out rule2.

This doesn't have to be done extremely well (see PEG/Packrat parsing for that) but even a little bit, maybe one term or something like that helps a lot.

I am no authority to speak about this - but I believe expanding sensors and improving on data gathering is a continuous and on-going effort (e.g., weather station on ships, airplanes, stations deployed on sea etc.). Better weather satellites are also a thing. But then there is just so much more that could be done and all these data-points are still unevenly distributed (e.g., planes and ships follow routes). Weather models are improving quite a bit “behind the scenes” but again - I think we are far away from getting anything reliable for several days into the future; not to speak months or years.

Here is a nice interview highlighting a couple of improvements people are driving for a niche sport weather forecast: https://magazine.weglide.org/skysight-interview-matthew-scut...

So much waffle. It's written like an online recipe, where we get the author's life story before they actually get down to business. If you're writing an article titled "The Socratic Journal Method" consider discussing the Socratic Journal Method as your first point. In 2025 is it really necessary to tell people they can journal on paper or on a computer?

> I look at compilations of programming safety errors in shipped code now and then. Far and away the #1 bug is out-of-bounds array access. D has solved that problem.

Do you have good data on that? Looking at the curl and Chromium reports they show that use-after-free is their most recurring and problematic issue.

I'm sure you are aware, but I want to mention this here for other readers. Reference safety extends to things like iterators and slices in C++.

This is what you did say

Like - how the fck would you know? Even more so, why the fck does your ignorance and inability to think of possibilities, or fully grasp the nature of anything make you think that that sort of comment is remotely appropriate.

You have the uniquely fortunate position to never be able to realise how inept and incompetent you are, but putting that on to other people is definitely only showing everyone your ignorance to the facts of life.

And there was no reply - just downvoting people, like a champ...

There was the (embarrassingly bad, even if you like gun control) “assault weapons ban” but since then democrats haven’t even been able to consistently achieve the thing that Republicans often say they want instead of more gun laws: “enforce the ones already on the books” (this is so common I assume it must have been pushed initially by some major Republican figure, but I’m not sure who it was) so the risk of their passing substantial gun control laws today is extremely low, even with decent majorities in the legislature and holding the presidency.

Meanwhile, the vast majority of democratic politicians are openly against outright bans and quite a few of them even mean it—Democrats managing to pass even some better version of the extremely-partial AWB is fantasy any time soon, and I very much doubt they’d get half their own people to vote to restrict firearms any more than that. (Setting aside that the courts have recently set perhaps the narrowest scope for allowable gun restrictions in the country’s history, so it might not matter even if they could pass any of this)

When I did a 2 week road trip from Chengdu to lijiang a couple of decades ago, we spent the first two days of the trip just acclimating on the Tibetan plateau at 3000 meters or at the town near siguniang. Then we hit places like daocheng (3500 meters), we drive through passes at 5000 meters, Litang town at 4000 meters (about the height of mt rainier). The biggest problem I had was the lack of vegetables that high, my teeth really got tired of eating judt meat and potatoes. The places were all populated though with Tibetans, they just lived up there as if it was the most normal thing in the world (heck, litang had 60k people living at 4k meters, that seemed crazy to me).

Really liked your post, the way you brought that old Indigo back to life was super fun to read. I totally agree that the magic is in seeing the machine actually run again, not just sitting on a shelf. For me, I’ve messed with a couple of old PCs before, but nothing as cool as an SGI box. Reading this makes me think I should try grabbing one if I ever spot it cheap. Thanks for sharing the journey—would love to see more pics of the messy steps too, not just the polished result. Feels like hanging out with a fellow retro nerd.

Agree. My personal take on this is a boring one: Like all things, it's a balance.

I'm introspective by nature (I'm sure many of us on this site are) and metacognition can be a very comfortable trap. It's a space where you can convince yourself that you can solve your life problems by spending enough time and effort thinking about them, the same way many of us approach engineering problems or other aspects of life. This is even worse in the era of AI, where you can have a helpful assistant to talk through your problems with and encourage analysis even further.

Turns out that's not true. You can spend as much time as you want thinking about your life, circumstances, emotions, experiences, etc. Eventually, you'll have to actually do something and go have some contact with reality.

It's helpful to examine your life and engage with your problems, but taking it too far is just another way of escapism. At least it was for me, YMMV.

Echo chambers aren't good but the large scale social media I've tried has a tendency to put me in an echo chamber (specifically one trying to wring out all the engagement possible, often with stuff to make me angry) and also elevate low quality opinions (often factually incorrect or philosophically incoherent).

Smaller and more personally curated social media has been better for sourcing broad opinions actually if I put just a little work into it.

I mean, if taxi companies could build their own Uber in house I’m sure they’d love to and at least take some customers from Uber itself.

A lot of startups are middlemen with snazzy UIs. Middlemen won’t be in as much use in a post AI world, same as devs won’t be as needed (devs are middlemen to working software) or artists (middlemen to art assets)

You just mentioned PostgreSQL, which, like pretty much every RDMBS sans MySQL, DB2/400, and maybe DB2/ZOS (never worked with the ZOS variant) supports schemas. If you need to worry about this, keep your tables that actually contain your data in one schema, then keep views, functions/stored procedures, etc. in separate schemas every time you make incompatible changes.

The database is a separate component, the biggest mistake nearly every developer makes is trying to make a single application own it. Let me tell you, from experience, the chances that this one single application will be the only thing that every connects to your database past initial development is slim. "Oh, but we're doing microservices and everything only ever talks over HTTP or gRPC" - yeah, sure, and I don't have a backlog of tech debt a mile long.

What you describe sounds like the opposite of my perspective.

You make it sound like stablecoins offer a benefit to all sides because of better technology.

My expectation is that they offer a benefit to the borrower because the borrower is less regulated and can lend out the money with higher risk and by doing so generate a higher yield.

You mention "1:1 backed thing, with super regulated entities" as if that means the money is safe. But as we have seen with Silicon Valley Bank, even lending out the money to the government via bonds is not safe enough in all circumstances. And my expectation is that issuers of stablecoins can do even more risky types of lending than Silicon Valley Bank did.
by madduci | 2025-09-14 06:12:56+00:00
Although this is correct, the narrative is obviously 100% centered on US perspective.

The author worries about the brain drain that could affect places like Pittsburgh, but on the other hand, people is already living it, as my kids just see grandparents once per year, since we live in another country, but there is people who can't even do it on an annual base, because they live far away or in countries considered at risk.

It is just below 9mm which I'll agree is impressive. Most of the dimensions are in the acceptable range compared to "Pro" models of competitive brands. But I find those already too much, and a pain to carry in most of my pockets.

It also cost over 2000€ which is more than a Pro iPhone plus iPad combo, while only giving you the benefit of being somewhat pocketable. It is not a better phone and a much worse tablet. If the thing is going too annoying to carry in pocket (particularly when cycling) and requires me to get a bag, I might as well have a bag big enough to carry the superior option which also happens to be cheaper and will get much better battery life (among other things).

It's a niche show-off device of little practicality. It is like small sports coupé cars. I understand why some get them but they will always be a way to attract attention more than anything else.

>Show me the reduction in cost for medical care when 1/4 of the doctors in the US are foreign born medical grads, the bulk of whom came through the H1B program.

If this is true it is a genuine national security emergency, not least because foreign standards for practicing medicine are not the same as they are here. I've never encountered a foreign born medical grad in all my years. Where do they work?

>These are smart people who end up in high level roles who end up staying and becoming Americans (agin raising the bar).

I didn't make any claim about the intelligence of H1b visa holders, though it's interesting that you immediately went on the defensive there. I'll say this: if you had a poor experience with American engineers that suggests there is a pipeline problem, no? Ostensibly, my government should be interested in fixing that problem since, allegedly, that's where its priorities lie. I totally get it that the H1b program allows companies to lower their demand signal to US-based institutions that would otherwise produce more of these people that you need. Sorry you worked with some shitty engineers, it happens.

This post was a bit difficult to parse; that's what it sounded like to me, although more as a interface-cleanliness feature than a rendering optimization. There also seemed to be an element of a non-euclidean/non-consistent-geometry idea there. (Which makes some sense - if you lean in or turn your head to get more UI detail you don't necessarily want it to take over your entire field of view. Although personally I think this might have the same problems as a "Minority Report"-style UI regarding long-term usability.)
by ubjp | 2025-09-14 06:17:47+00:00
The difference is in the assumption of "higher risk". Most of this borrowing is eventually the US Govt because the stablecoins are backed by T bills. So its not as much of an arbitrage as you say.

But then can you have a world where all the money is only stablecoins and backed by "something"? I think that has interesting implications for monetary supply and central banking

> you can lend out the money you earn from selling someNiceCoin to services with higher yields.

> And my expectation is that issuers of stablecoins can do even more risky types of lending than Silicon Valley Bank did.

To be clear - stablecoin issuers are not allowed to "lend" the money out like a bank or a regulated lender _at all_ - much less doing "riskier" lending. Bridge and Circle still have to, by law, maintain 1:1 cash/cash-equivalent [0] reserves, which means the best they can do is things like US treasuries / money-market funds - which are also primitives accessible to consumers and businesses directly (ie. not inherently competitive).

Certainly there is still great benefit to Bridge, Circle, and the customers issuing stablecoins through them - because it gets them MMF/treasury yield without having to do a "stored value" program at a bank etc - but the issuers who are converting user deposits into stablecoins are also only getting user deposits in exchange for doing useful things.

People don't deposit funds into Mercury just because Mercury gives them 4% (there are plenty of places you can get 4%). You put money into Mercury for the software - this is primarily an implementation detail of how Mercury manages that money, affords to give you a competitive (4%) rate, and affords to give you great software.

Most countries and transnational organizations continue to use English as the primary lingua franca, even despite China becoming a major R&D hub.

The EU continues to use English as the lingua franca for scientific communication due to the diversity within the EU.

On the India side, research done as part of the pact with Japan [0], Taiwan [1], South Korea [2], the EU [3], and the US [4] is done in English.

And on the Vietnam side (based on my SO's experience), all of her ASEAN-Japan and ASEAN-SK collaboration was done in English as well.

Sure, but that's not a problem, right? People are wrong all the time, it's fine. Also, it seems quite natural that a person who hasn't lived the entire life yet hypothesizes about what I'll be like, what it should be like and what it's like for other people. Moreover, what they say seems to be based on at least one research paper, so this is basically top quality wrt the internet's standards

Feels like visual programming keeps trying to be “code, but with pictures” instead of asking what problems pictures are actually good at solving. We’ve basically been drawing the same boxes and arrows since the 80s and wondering why it still feels like wiring up a VCR.

If we really leaned into the visual cortex, maybe we’d get something where zooming out shows the big picture and zooming in shows the gritty details, like Google Maps for code. Until then, node‑and‑wire diagrams are just UML diagrams that decided to cosplay as circuit boards.

Weren’t you, in your initial post, suspicious that the research process was settling on a pessimistic consensus view? Figuring that, because most every formal study is coming up negative (or “no effect supported”), it must be that the research is selective and designed to manipulate? And that a phenomenon can’t exhibit a diversity of uniformly bad effects without “an underlying reason that has been left unstated and unproven”?

I don’t know how I’d state or prove a single underlying reason why most vices are attractive-while-corrosive and still, on the whole, bad. It feels like priests and philosophers have tried for the whole human era to articulate a unified theory of exactly why, for example, “vanity is bad”. But I’m still comfortable saying gambling feels good and breaks material security, lust feels good and breaks contentment (and sometimes relationships), and social media feels good and breaks spirits.

I certainly agree that “social media” feels uncomfortably imprecise as a category—shorthand for individualized feeds, incentives toward vain behavior, gambling-like reinforcement, ephemerality over structure, decontextualization, disindividuation, and so on; as well as potentially nice things like “seeing mom’s vacation pics.”

If we were to accept that social media in its modern form, like other vices, “feels good in the short term and selectively stokes one’s ego,” would that be enough of a positive side to accept the possibility for uniformly negative long-run effects? For that matter, and this is very possible—is there a substantial body of research drawing positive conclusions that I’m not familiar with?

https://anycrap.shop/product/tentative-manipulator

The Tentative Manipulator resembles a handheld puppeteer's rod, but instead of controlling marionettes, it manipulates probability fields around objects within arm's reach. Users can nudge reality slightly towards desired outcomes by wiggling the handle, creating unforeseen possibilities at will. However, successful applications rely heavily on faith and intestinal fortitude; results may vary wildly depending on operator confidence levels.

When attempting complex tasks, users must synchronize their inner monologue with precise hand movements, forming a symbiotic relationship between intentionality and gentle wrist motions.

One can compensate with (steam)pressure and/or duration. Or cold brewing.

In practice I note not that much difference at about 2500m altitute, where my main residence is. French/Aeropress suffices. 100°C isn't necessary. Even only 90°C suffices.

Similar for good Tea. You destroy that with 100°C. Very good Tea should be brewed at 60 to 70°C for greens, blacks more like 70 to 85. Though the hardness/pH of the used water is equally important for them. For coffee not so much.
