The S&P 500 historically returns about 10% annually with a Sharpe ratio around 0.5-0.6. This fund's metrics show it outperforming on both absolute and risk-adjusted bases. The 36.35% CAGR is excellent.

Now, imagine if you could trade on the information when they do.

June (nine)teenth, seems pretty straightforward to me. Clearer than All Hallows' Evening --> Halloween.

>I bet if you I were to walk down the street here and ask 10 people what Juneteenth is only 1 would be able to do better than: "something to do with freeing the slaves".

And lots of people think Cinco de Mayo is Mexico's Independence Day, doesn't make the holiday any less valid. It's just an issue of education.

I just hit my usage limit this morning, and the article shows how to get these numbers so I can answer this myself -- I'd be curious to see what other people are doing token wise day-to-day

ccusage says I had 1k input tokens, 12k output and 1.2m cache create.

I'm not sure if that is 18.3g, 138.3g or 1213 * 8.3g.

At the highest number that's 10kg or 25% of average US daily per capita emission or 1 gallon of gas.

The article was commissioned by refactoring.fm, which, naturally, features Refactoring AI!

Unsurprisingly the article comes to the conclusion that anyone can be trained, that 10x engineers are overrated, etc. The AI promotion strategy seems to be improving: AI is not mentioned in the article, but individual learning and meritocracy are dutifully devalued to fit the narrative.

> a notorious game requiring a large amount of skill to play, and isn't a tax on the math illiterate.

Nobody but you mentioned skill. Plenty of mathematically literate people play the lottery for fun, knowing the the expected value is a loss. I personally oppose these types of state operated lotteries as regressive forms of taxation, but if they exist, they shouldn't serve the purpose of allowing capital (especially foreign capital) to extract even more money from citizens.

I finally gave in and created an account because of your comment. It's beautifully put. I would only perhaps add that, to me, the neo-rationalist thing looks the most similar to things that don't work yet attract hardcore "true believers". It's a pattern repeated through the ages, perhaps most intimately for me in the seemingly endless parades of computer system redesigns: software, hardware, or both. Randomly one might pick "the new and exciting Digg", the Itanium, and the Metaverse as fairly modern examples.

There is something about a particular "narrowband" signaling approach, where a certain kind of purity is sought, with an expectation that, given enough explaining, you will finally get it, become enlightened, and convert to the ranks. A more "wideband" approach would at least admit observations like yours do exist and must be comprehensively addressed to the satisfaction of those who hold such beliefs vs to the satisfaction of those merely "stooping" to address them (again in the hopes they'll just see the light so everyone can get back to narrowband-ville).

Servus from Munich: as you may know: Munich is now the most unfriedly city in the world. This comes from a Mix of the Grantler, Mia San Mia and Schickeria culture. The first is the traditional grumpy nature of the typical Bavarian (especially Oberbayern). Sone say this is because of the Föhn wind (warm, dry downdraft that occurs on the leeward side of alps mountains) which can cause headache and paired with a massive beer consume even more. Mia San Mia and Schickeria is only typical in Munich: Many people from all over Germany moved to Munich in the 60s and 70s and earned money and build up an extreme snob culture seeing theirself as better as the rural people in Bavaria. https://www.express.co.uk/news/world/2048237/incredible-euro...

Hamburg is more conservative than Munich (I have lived in both cities). It is more like Austin wehen you compare it to a city in Texas. And Hamburg is in no way as hippy as San Francisco was. The closest I would compare Hamburg to is Boston.

In the golden 70s Munich was a melting pot for musicians, gay people, Hippies. They still have the nudist beach in the city centre. Try to find something like that in the US.

well, maybe that explains why I've gravitated hard away from general-purpose backend work :)

I've had a great time on teams where folks can go off and build great tools/libraries/etc that others can use and adapt, without needing a whole team around them—ideally there's lots of collaboration, but it doesn't have to be formally structured

I guess the main difference is that you don't have to operate a tool or a library; if somebody has issues with it, they can patch the code themselves or simply adapt around it in their own code

I also enjoyed working on simulation and optimization problems for similar reasons; there's lots of direct business value, but there's enough slack around it that if I go somebody else can take a model over and maintain it without any issues

unfortunately lots of organizations do not know how to make library-style code "count" the same way a service or stateful component "counts"
Ask HN: LinkedIn removes your profile as precaution?
by artur_makly | 2025-06-19 19:21:25+00:00
72 hourss ago,for no apparent reason that I can tell, Linkedin restricted my 15-yr old account.

It then asked me to submit a gov ID and take a photo.

Thereafter, no email receipt was sent. no case #.

"Your account has been temporarily restricted as a precaution"

Why did this happen? We take proactive steps to secure your account when we detect potential unauthorized access. Signs that your account may have been compromised include account access from unfamiliar locations or devices, or unusual activities such as multiple attempts to change passwords or critical settings.

What can you do next? To help you keep your account safe and regain access, we’ll first need to confirm you’re the valid account owner. Please submit a government-issued ID to start the process.

A customer support representative will contact you within 48 hours with more information about your account and the status of restoring your access.

It's already been 72hrs..I'm even on their Premium Plan. No contact # to call. Nothing.

Any advice would be appreciated. thanks

"Unsecured DNS over 53/tcp+udp (vs. DoH today) is a huge spoofing and metadata collection threat surface"

Genuinely curious:

What actor, in 2025, would exist in your threat model for DoH ... but wouldn't simultaneously be sniffing SNI ?

I can't think of any.

I cannot think of any good reason to be serious about DoH and DNS leakage in the presence of unencrypted SNI.

What am I missing ?

I have never heard of anyone recycling an incandescent bulb, but recycling bulbs became a big deal with CFLs came out and most people seem to be in the habit in the area I'm in. Store have bulb take-backs for CFL/LED in the entryway, for example.

I don't like LED bulbs, but I think they clearly win the disposal/economical argument against incandescent in every way. Unfortunately they blink and have poor color reproduction in many versions.

Sure, I have seen the detrimental impact on some teams, and it does not play out as Marketers suggest.

The trick is in people seeing meaning in well structured nonsense, and not understanding high dimension vector spaces simply abstracting associative false equivalency with an inescapable base error rate.

I wager Neuromorphic computing is likely more viable than LLM cults. The LLM subject is incredibly boring once your tear it apart, and less interesting than watching Opuntia cactus grow. Have a wonderful day =3

> The moment you think something like "I am more correct than this other person because I am a rationalist" is the moment you fail as a rationalist.

Well said. Rationalism is about doing rationalism, not about being a rationalist.

Paul Graham was on the right track about that, though seemingly for different reasons (referring to "Keep Your Identity Small").

> If you're saying "well actually, I'm right" more often than "oh wow, maybe I'm wrong", you've failed as a rationalist.

On the other hand, success is supposed to look exactly like actually being right more often.

A few thoughts/ideas on using this in Kubernetes are discussed in this issue: https://github.com/psviderski/unregistry/issues/4; generally, should be possible with the same idea, but with some tweaking.

Also have a look at https://spegel.dev/, it's basically a daemonset running in your k8s cluster that implements a (mirror) registry using locally cached images and peer-to-peer communication.

As I said, I don't reject LLMs for every situation (what you describe would probably fit the "iterative design" category). But as soon as this personal affair meets the wider world, inevitably becomes too big and transient to be thoroughly understood, and accelerates the rate of minimally-supervised code reviews sent to very human peers ; is where I have a bigger issue: individual convenience shouldn't incur more work and effort to others, nor become an increased risk to stakeholders.

It is in that sense that I see LLMs challenge "social contracts": their use is infectious (probably also in the GPL-sense, be warned) and should be agreed upon by all parties upfront (do you want to be on the receiving end of a software that you pay good money to have developed while knowing that its developers have little understanding of its workings? How many times cheaper is cheap enough to pay-off the amount of technical and institutional debt/risk? Can LLMs effectively become that cheap?).
Show HN: Run your favorite open-source AI coding agent in the browser

Hey HN,

As a developer who's always been intimidated by the terminal, I found using terminal-based AI coding agents like Aider, Codex, or Plandex an obstacle.

To solve this, I built a browser-based UI that brings the power of these tools to a familiar web interface.

>Science should ALWAYS be free to ask questions and explore them no matter how uncomfortable they sound. And this is a huge overreaction to how the left politicized science their way and continued to say that’s it not political.

Like when a google employee was free to ask questions as to whether it was that women don't like programming as much as men, and got immediately fired? Because of course the cause is sexism.

Like when James Watson had suggested intelligence was genetic, and if races differ genetically, so too may their intelligence... also fired from Stony Brook leadership. Because of course alleles that confer intelligence genetically are magically perfectly balanced in frequency across all races.

Not to pick on leftists for ruining careers, the right has done this to leftists as well - see David Bohm, a Pennsylvania native and at the time brilliant contemporary of Richard Feynman, who lived out his life in Brazil because McCarthyism got him.

Thing is, the left did politicize science, just read Nature: https://www.nature.com/collections/daficfhiff

Or you can read what you need to get a professorship: https://mitcommlab.mit.edu/eecs/commkit/faculty-application-...

DEI is essentially a commissar type system where one must pledge to the political officer allegiance to the cause, one where proletariat origins are favored over bourgeois. Trump's response is heavy handed but what is happening here is poisonous and insidious, insofar as outright hiring one demographic group over another is universally seen as evil, but hiding it behind a process of bureaucracy and good intentions somehow transforms it into virtuosity. DEI is basically a parasite that has infected many systems and hurt many people, it would be more elegant to simply remove the parasite, but Trump's tactic of taking a metaphorical flamethrower to the parasite and its host both will garner popular support given a lot of people have a bad taste from DEI.

As Adam Becker shows in his book, EAs started out being reasonable "give to charity as much as you can, and research which charities do the most good" but have gotten into absurdities like "it is more important to fund rockets than help starving people or prevent malaria because maybe an asteroid will hit the Earth, killing everyone, starving or not".

> Juneteenth marks the day 2.5 years later that the last known enslaved people were freed

Nope, just the last in the Confederate States; the last Union chattel slaves (e.g., in Delaware) were freed by operation of law a few months later with the ratification of the 13th Amendment.

(And that's not even discussing penal slavery allowed under the 13th Amendment.)

Althought Base44 seems to be a wrapper on ChatGpt but output is far superior. I tried "adminLTE port to React" via both; Chatgpt gave me a very barebone stuff besides the dashboard page, which had mild functionality. However, Base44 provided me with a fully functional app.

Edit: Just learnt from comments, they used Claude and not ChatGpt.

Not saying they are malicious actors, but easy answer would be any Public WiFi anywhere. They all intercept DNS, less than 1% intercept SNI.

It is also public knowledge that certain ISPs (including Xfinity) sniff and log all DNS queries, even to other DNS servers. TLS SNI is less common, although it may be more widespread now, I haven't kept up with the times.

I cannot possibly disagree with this more, "Juneteenth" is far superior.

Part of it is that it absolutely invokes AAVE. It forces people to consider and be reminded of Black American culture; "Emancipation Day" whitewashes the history a little bit and gives a little too much credit to the so-called "emancipators." Let's keep this centered on Black folks, where it belongs.

Invoking questions is a feature, not a bug.

They were extremely clever but I strongly object to characterizing the program as “scrappy”.

They were doing beyond bleeding edge stuff with zero compromise. They didn’t settle. They just kept inventing until they had the capability they needed. Then they moved on to making the next impossible thing possible.

The Apollo Guidance Computer used the first integrated circuits. Like, literally the first batches manufactured went into the AGC. 2/3 of the national supply of a brand new technology is not “scraps”.

They went to the absolute limit of what was technologically possible then and is not technologically possible today. I understand that’s the reason for the Iron Man reference but it just doesn’t work here. The 1960s were not the stone age. Apollo was thousands of Tony Starks with the full backing of the United States. Not a couple guys in a cave fighting for their lives.

Wytham Abbey was bought mainly to host internal workshops and "retreats", as outlined by the people who bought it https://forum.effectivealtruism.org/posts/xof7iFB3uh8Kc53bG/... https://forum.effectivealtruism.org/posts/yggjKEeehsnmMYnZd/...

As far as I know it's never hosted an impress-the-oligarch fundraiser, which as you say would at least have a logic behind it[1] even if it might seem distasteful.

For a philosophy which started out from the point of view that much of mainstream aid was spent with little thought, it was a bit of an end of Animal Farm moment.

(to their credit, a lot of people who identified as EAs were unhappy. If you drew a Venn diagram of the people that objected, people who sneered at the objections[2] and people who identified as rationalists you might only need two circles though...)

[1]a pretty shaky one considering how easy it is to impress American billionaires with Oxford architecture without going to the expense of operating a nearby mansion as a venue, particularly if you happen to be a charitable movement with strong links to the university... [2]obviously people are only objecting to it for PR purposes because they're not smart enough to realise that capital appreciates and that venues cost money, and definitely not because they've got a pretty good idea how expensive upkeep on little used medieval venues are and how many alternatives exist if you really care about the cost effectiveness of your retreat, especially to charitable movements affiliated with a university...

If that happened, we'd revert to pre-DNSSEC security levels: an attack would still be hard to pull off (unless you own a root DNS server or are reliably in the path to one). It's like knowing the private key for news.ycombinator.com - it still doesn't do anything unless I can impersonate the Hacker News server. But that was still enough of a risk to justify TLS on the web. Mostly because ISPs were doing it to inject ads.

> But you can try and improve the metrics within a single project.

Yes. But it means that it doesn’t let you assess code quality, only (at best) changes in code quality. And it’s difficult as soon as you add or remove functionality, because then it isn’t strictly speaking the same project anymore, as you may have increased or decreased the essential complexity. What you can assess is whether a pure refactor improves or worsens a project’s amenibility to AI coding.

the best manager I ever had was a VP who came from a banking background—the key thing was not that he had written a lot of production software himself, but that he had seen what great software looks like (apparently he worked closely with the core Slang/SecDB guys), and was willing to trust engineers who could build similar styles of tools

on the other hand, the recent skip-level I had that got me to quit in six months was an engineer himself, but had no real opinion on code quality or anything more than a superficial, process-oriented understanding of the dynamics on the team :(

moral of the story: taste is necessary; direct technical experience is mostly necessary, but nowhere near sufficient

Well, in Wayland, the same apps just don't work at all. The developer basically has to rewrite them and turn them into different apps to make them work in Wayland. Is that good or bad? Maybe if you hate a certain type of app it's good, but this is the open source world and if something doesn't hurt anyone then you should probably be allowed to do it. It's not the display server's job to rule by fiat. It might be the window manager's job, but only if the application-provided coordinates don't work, or you're using something strict like a tiling WM.

(Thank you) I agree, although I do think that the rationalists and EAs are way better than most of the other narrowband groups, as you call them, out there, such as the Metaverse or Crypto people. The rationalists are at least mostly legitimately motivated by morality and not just by a "blow it all up and replace it with something we control" philosophy (which I have come to believe is the belief-set that only a person who is convinced that they are truly powerless comes to). I see the rationalists as failing due to a skill issue as well: because they have so-defined themselves by their rationalism, they have trouble understanding the things in the world that they don't have a good rational understanding of, such as morality. They are too invested in words and truth and correctness to understand that there can be a lot of emotional truth encoded in logical falsehood.

edit: oh, also, I think that a good part of people's aversion to the rationalists is just a reaction to the narrowband quality itself, not to the content. People are well-aware of the sorts of things that narrowband self-justifying philosophies lead to, from countless examples, whether it's at the personal level (an unaccountable schoolteacher) or societal (a genocidal movement). We don't trust a group unless they specifically demonstrate non-narrowbandedness, which means being collectively willing to change their behavior in ways that don't make sense to them. Any movement that co-opts the idea of what is morally justifiable---who says that e.g. rationality is what produces truth and things that run counter to it do not---is inherently frightening.

> There’s no good way to solve this, though.

Yes there is! Just get rid of it. It's useless. The re-implementation from using one to the other was barely a few moments of work, and even if you want to say "well that's a breaking change" I mean, yeah? Then break it. I would be far less annoyed if a function was just removed and Xcode went "hey this is pointed at nothing, gotta sort that" rather than letting it run in a way that turns the use of authentication functionality into a landmine.

Local hard drive are big enough these days to hold hundreds of millions of files. That means that you could have many millions of each type of file (documents, pictures, spreadsheets, videos, etc.)

We need better ways to properly classify all that data with accurate metadata and quick ways to pick out a small subset of data for A.I. to analyze.

Databases were designed to do this with relational tables (e.g. find all customers from New York who bought our product in 2024); but file systems were not designed to do this with files (e.g. find all pictures I took with my phone in 2020).

A.I. can be a great tool to find patterns in files to answer important questions, but it will be incredibly slow if it has to analyze too many files for every query.

The root cause is Americans, generally, prefer any mode of transit other than rail, so passenger rail isn't profitable, so train companies naturally prioritize freight.

For what it's worth, I like traveling by train and do so whenever I can, but I'm an outlier. Most Americans look at the travel times and laugh at the premise of choosing a train over a plane. And when I say they look at the travel times, I don't mean they actually bother to look up train routes. They just know that airplanes are several times faster. Delays suffered by trains never get factored into the decision because trains aren't taken seriously in the first place.

>> 37.4%? That's 27m kids! How can CPS run so many investigations? That's 4k investigations a day over 18 years,

> 800 people with my wife's qualifications and caseload is equivalent to 4000/day. there's ~5000 caseworkers in the US

I don't know what the number of children in the system is. as i said in the comment you replied to, here. but the average US CPS worker caseload is 69 cases. which is over 300,000 children per year, because there are ~5000 CPS caseworkers in the US.

I was only speaking to "how do they 'run' that many investigations?" as if it's impossible. I pointed out it's possible with ~1000 caseworkers.
