What's funny is that OP thinks anti-Trump posts being flagged suggests HN is pro-Trump, while not noticing that pro-Trump posts don't exist here at all. Unless they're deleted immediately (seems unlikely), people with that opinion have just learned to keep it to themselves (or go away) because it'll only destroy their karma here.

That suggests that HN leans heavily anti-Trump, but also doesn't want to talk about him all the time, so flags posts that drag the forum in that direction. Ditto Musk and "fascism," whatever that's supposed to mean nowadays when everyone to the right of Mao gets called a fascist sooner or later.

Not Recently. 2010ish was working for an insurance processor that was actively writing thousands of lines and executing on z/OS with no plans to migrate.

I was part of team that was writing web applications that needed to call z/OS transactions. The IBM solution was to use their Transaction Gateway product, which cost a ton, and was slow as shit. We developed a framework that used annotations on the Java Side to map COBOL Records to Java Objects and invoke transactions over a TCP socket. Learning how to pack decimals and convert encodings was pretty cool. We ended up with a framework that was at least a zillion times faster than the IBM solution. Left that job though as the company was is distress and was losing customers (health plans). They eventually folded.

I remember a case (in Eastern Europe) where someone who took a video of their colleagues sleeping during a night shift got in trouble for the usage of phone (which is known to be used BTW), and nothing happened to the ones sleeping through the night shift. We are talking about a facility full of people with dementia and are known to go back and forth the hospital for serious falls and all that (at night, too). So backwards.
Show HN: Drop-In Checkpointer for LangGraph (No DB Setup Required)
by raunaqvaisoha | 2025-07-18 14:28:56+00:00
Hey HN!

I built Convo SDK after spending way too many hours wrestling with LangGraph checkpointer implementations. Every time I wanted to add memory to a LangGraph agent, I'd end up in database setup hell.

The Problem: - Setting up PostgresSaver means managing connection pools, schemas, migrations - MongoSaver requires MongoDB hosting, backup strategies, monitoring - Custom BaseCheckpointer implementations are 100+ lines of boilerplate - Production failures from connection pool exhaustion, timeout errors - Infrastructure costs pile up fast

The Solution: Replace any LangGraph checkpointer with one line:

// Before: 50+ lines of custom PostgresSaver setup const checkpointer = new PostgresSaver(connectionPool);

// After: One line const checkpointer = convo.checkpointer();

What makes it different: - Drop-in replacement for any LangGraph checkpointer - Cloud-native persistence (no database setup required) - Thread management for multi-user apps - Checkpoint restoration for debugging

Tech Stack: - TypeScript-first with full type safety - Works with all LangGraph patterns (ReAct agents, custom workflows) - Handles async operations and human-in-the-loop - Compatible with existing LangChain ecosystem

I've been using this in production for 6 months and it's eliminated all our checkpoint-related infrastructure headaches. The API is intentionally minimal - just init, get checkpointer, and you're done. I've now released it in an open beta and am excited to share it with the world.

Would love feedback from other LangGraph users! What's been your experience with checkpointer implementations?

https://www.propublica.org/article/liberty-healthshare-healt...

> For generations, members of the Beers family of Canton, Ohio, have used Christian faith to sell health coverage to more than a hundred thousand people like Martin. Instead they delivered pain, debt and financial ruin, according to an investigation by ProPublica based on leaked internal documents, land records, court files and interviews. They have done this not once but twice and have faced few consequences.

Even the legit ones don't have to cover stuff; they aren't health insurance. Even if they do, many facilities and docs won't take it, because they aren't required to cover things and they don't want the fight.

Came here to make the same joke.

Also it's technically Romneycare. The political right got everything it wanted with it, similarly to when Nixon passed HMO funding that tied insurance to work, basically forcing a work requirement in order to get healthcare:

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

This might be the biggest thing that caused US healthcare to double in cost vs the rest of the developed world, which provides universal or single payer healthcare to their citizens for free or nearly free.

Also the article got the numbers wrong. To be accurate, they should have said $400 or more, roughly $5000 per year for working adults pushing 40. More for families. That was 10 years ago when I was applying, I'm sure it's more now.

I'm surprised that a startup isn't providing transportation for medical tourism. A friend of mine lived in Costa Rica for a while decades ago, and care was covered even for noncitizens. So a round trip ticket and living abroad for weeks would still be cheaper than insurance plus deductible here.

It's to the point where half of you will block nationalized healthcare for the other half, even though we would continue paying double to cover you for free too. So much for objectivism.

Edit: I forgot my point, which is that I believe that healthcare may be a natural monopoly, which is when something that everyone needs must be regulated, or else it becomes a monopoly where the vendor charges as much as possible because people have no choice:

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

Other examples include electricity, water, sewer, trash and probably education.

Subsidies are going away but they're raising the unsubsidized rates because of that. This is the key paragraph:

> If healthy people opt out, the insurance pool is left with those who cost insurance companies more — people who can't go without health insurance because of chronic conditions or expensive medications. "That's why insurance companies are going ahead and charging a higher premium, with the expectation that the market is going to get sicker next year

Banks usually have a mechanism to prevent automatic billing/card data updates for exactly that reason for suspected/confirmed fraudulent used cards, but unfortunately not all of them, and I suspect even for those that do, not all customer service reps know how to do that.

In an ideal world, all merchants would be using tokenization already – then the bank could offer you a UI where you can just kick out the merchants you don't want to have access to your payment credentials anymore before reordering a new card. (If tokens were mandatory, like they are e.g. in India, you wouldn't even need to reorder the card in the first place, but that'll probably never happen in the US – too many legacy systems.)

This seems more interesting as demonstration of the amortized performance increase you'd expect from using io_uring, or as a tutorial for using it. I don't understand why I'd switch from using something like eza. If I'm listing 10,000 files the difference is between 40ms and 20ms. I absolutely would not notice that for a single invocation of the command.

> If it tears the nation apart what does it matter?

If it does what now? Fearmongering that intentionally whips up nativist xenophobia might do that. I'm not seeing how work visas in themselves would do it.

> Second, even when they do have US degrees enriches institutions and people that at best about half the country approves of and approximately nobody not getting paid by them approves of the economic model of.

I honestly don't know which institutions and people you're talking about. I can think of several fundamentally different candidates.

> This nation is in the shit is is because of you and people like you who adopt or condone policy positions based on something other than principals.

You're being self-contradictory. Either you have principles to which you hold regardless of whether "this nation is in the shit", or your only "principle" is "do whatever works to keep you out of The Shit(TM)". Which isn't really a very inspiring principle. Anyway, as soon as you start doing things for instrumental reasons, you lose your deontologist card.

If your principle actually is "stay out of The Shit by any means necessary", then you have to prove that what you want to do actually works to keep you out of The Shit. Starting by defining what "The Shit" means to you. Maybe what works is building up industry.

What you've offered only works on exactly the same kind of "principles" as doing things "to build up US industry".

An actually principled approach to H1Bs might, for instance, be to convert them into permanent residencies or citizenships, because indentured servitude is ugly on principle. That'd also have the practical effect of making people less beholden to specific employers, thus reducing the negative effect on anybody they might be competing with, but that's not the principled part unless you can say what actual, specific principle it serves.

... and, by the way, for any actually reasonable definition, your nation (no longer mine) wasn't particularly "in the shit" until recently. Just normal fluctuations. It hasn't actually even really landed in "the shit" yet, although the people running Trump have succeeded in breaking its last hold on the the catwalk over the shit vat.

> instance how `less` became `more` on most systems

How `more` became `less`.

The name of 'more' was from paging - rather than having text scroll off the screen, it would show you one page, then ask if you wanted to see 'more' and scroll down.

'less' is a joke by the less authors. 'less is more' etc.

My biggest piece of starting advice would be use it for exploration not generation. It can be great for understanding code bases and looking at git history.

Context is key, so it is also really helpful having a CLAUDE.md file; the /init command can create one for you.

If you are going to use it for generation (writing code); plan mode is a must. Hit shift-tab twice.

Finally; I'm mostly using the claude 4 sonnet model, but make sure to tell it to "ultrathink" (use those words); this means it can use more thinking tokens.

Platinum plan (which winds up most fiscally responsible for us - we max out the low out-of-pocket-max reliably), four people. Something like a bronze plan wouldn't save us any money; lower premiums trade for high deductibles and copays. Good if you're healthy.

The only thing other CAs do (after EV certificates stopped being a thing, as a sibling commenter already mentioned) is to take more money from you than Letsencrypt, in exchange for longer validities and historically some other concessions (although the browser forum has been clamping down on that, for good reasons).

In other words, if the bank is following best security practices, they're fine with Letsencrypt; if they don't, they might need somebody else.

There's a lot of media disinformation goes into keeping people that way.

I'm somewhat hopeful with Gavin Newsom's posture making an example, I wouldn't vote for him, but I like the aggressive PR position he's taken, his willingness to gerrymander just as the other side has been doing forever. That's what I mean by bipartisanship is dead. You can't negotiate with the other side, they do not want to negotiate, they want to win at all costs for ideology, so you can only do your best to disempower them. If you try to play fair with a counterparty who does not believe in acting in good faith or playing fair, you have default lost. You can't have a functional democracy when one side rejects democracy (massive efforts to disenfranchise voters, gerrymandering, etc) because they can't win democratically. There is no reason you can't have empathy while punching down at bullies, because if the tables were turned, the bullies would put their boot on your neck ("paradox of tolerance"). So, start punching down.

Edit:

In the context of this topic and the near term, this looks like blue states implementing universal healthcare, and letting red states figure it out themselves (considering how dependent red states are on the federal government [1] [2]); Oregon is up first [3]. You can increase state taxes to fund this, reducing tax dollars sent to the federal government, if properly engineered.

You can get 90% of the benefit of these longevity clinics for 10% of the cost.

First, advanced blood testing can cost <$200. Get ApoB and Lp(a) for heart health. hs-CRP for inflammation, A1c for diabetes, eGFR for kidney health, etc. https://www.empirical.health/product/comprehensive-health-pa...

Then, determine your nutrition goals based on your blood test results. For example, if your ApoB / LDL cholesterol is high, focus on getting more fiber and less saturated fat. If blood pressure is high, focus on potassium and sodium.

Exercise & sleep - use an Apple Watch or similar to track VO2Max and sleep stages.

MRI - I'd probably skip the MRI for cancer screening. While I think this will be the future, the evidence base is just not strong enough today to know what to do with the results. You can do a FIT-based colon cancer screen at home for <$10 (colon cancer is affecting people at younger and younger ages). Mammography and cervical cancer testing in a regular doctor appointment.

CAC scan (assessing calcium buildup in the arteries) - do if ApoB is high. You can book these for $200.

There are two options: you pay for health care for the poor through taxes, or you pay for health care for the poor through higher insurance rates.

Reagan was the one who brought socialized health care to America. He passed a law saying that hospitals couldn't refuse emergency treatment due to inability to pay. So uninsured people wait until their conditions are bad enough to be considered an emergency, and then show up at the ER. So hospitals have to jack up their rates for everybody to cover the cost of emergency treatment of the uninsured. Expensive treatment that would likely be much cheaper if treated before it became an emergency.

So this Trump move won't save you money, it just changes how you pay.

Unit test coverage is exceptionally high for the interpreter, and always has been:

https://micropython.org/resources/code-coverage/

('py' folder: 99.2% line, 88.7% branch coverage)

Testing the port-specific code has been a much more challenging problem.

Which is why in the past year or two there's been a lot of energy put in to HIL testing. There are now a few dozen boards that are automatically tested with an increasingly rich suite of hardware tests. Both the number of boards and tests are increasing rapidly.

It's not perfect but it's getting pretty darn good. If you want to help out please do reach out.

Smiles from Detroit. I would look to press those parts, since most contact surfaces are potentially convex and variant-depth parts appear superfluous to requirements. With a shared punch and die you could pull the nest off a laser, press them all in parallel, and break them after the parallel press-forming. Should be cheaper than injection because the cycles can be faster, the material can be stronger, there's only one die, and the unload will be easier?
Ask HN: Thoughts on combining static analysis and AI for system understanding?
by kanwarb | 2025-07-18 14:38:25+00:00
Working across multiple repos means constantly losing context. Most tools either search docs or try to feed entire codebases to LLMs (which fails).

I'm building something that uses static analysis to map relationships first, then gives that structured context to AI. For example: "what breaks if I change this auth function?" or "what code do I need to touch to add billing?" and it traces dependencies and business logic across all your repos.

Always wanted to leave the developer community better than I found it. This is a problem I've personally felt for years: context gathering. Good approach or am I missing something obvious?

They really are. I had a parttime coworker who moonlighted some mainframe job and he often had another laptop on his desk connected to a z/OS terminal. He would show me some of the jobs and code occasionally too, really fascinating stuff, and he was quite good at it and could navigate quickly.

And where did they get the political capital to do that?

They got it from the approximately half of society that they could pander to by saying "look, we did that, vote for me and I'll take it even farther" at the next cycle.

The ACA is going to go down in history as something that caused some yet unknown number of decades of suffering because it was just barely too much just barely too soon. If they'd have kept it in their pants another decade or maybe even less, or legislated a more incremental solution at the time we'd probably be 5yr into something workable by now.

The article is focused on general ossification of TCP preventing newer improvements from functioning. E.g. "performance enhancing proxies" from the article is not a euphemism for censorship, it's boxes design to do one thing with TCP which ends up breaking something for MPTCP. Any bypassing of censorship by avoiding ossification is completely incidental (and likely some extremely bad censorship if it just allows any protocol it can't filter through).

>Welcome to year 30 of trying to prove psilocybin works for psychiatric illness.

That is true, but it misses some important nuance: the war on drugs has effectively eliminated the ability for legitimate researchers to do significant research on these criminalized drugs.

For example, for me personally, a mild dose of marijuana is as effective as Zolpidem (Ambien) as a sleep aid, but without the lethargy and mental fog the next morning.

Blood oxygen sensing is disabled in the US (due to the patent lawsuit with Massimo), but it still estimates VO2Max and sleep stages.

VO2Max is based on GPS and heart rate sensor measurements, processed by a deep learning algorithm that uses physiological ODEs (ordinary differential equations). Very cool algorithm.

Apple Watch sleep stages (and sleep apnea detection) is based only on 3D accelerometer data.

In all seriousness, I would be more interested in the results of a simulation with more rows of parking.

Your reasoning is well taken and haven recently read Hofstadter's "Surfaces and Essences" the idea of what is a thing and what is not is fascinating.

Some of the criteria are questionable to me. For example, some monuments or memorials are still buildings, such as a mausoleum. Would your survey respondents deny a mausoleum is a building?

I could also ask myself, would I consider the Statue of Liberty a building? It is in active use; it has some usable interior volume; it is free-standing above the surface. And yet I hesitate to call it a building more than I hesitate to agree a lighthouse is a building.
