> VR flight simulator software is accessible to the layman. Does that make them qualified to be a captain (pilot-in-command) for a commercial passenger plane?

No. They might be able to fly a plane poorly, though. Engineer doesn't imply being qualified, only engaging in the act of designing, building, or maintaining a machine, structure, or system. You don't have to be qualified, or even be good at it, to carry out those acts.

You're probably thinking of Professional Engineer™, which does represent recognized qualifications, but that's something completely different. Obviously if Professional Engineer™ was meant, Professional Engineer™ would have been written.
Show HN: Krnel-Graph, a Library for LLM representation engineering and control
by gcr | 2025-11-03 16:38:46+00:00
Hey HN! My co-founder and I built Krnel-graph, a library for training and evaluating lightweight probes based on LLM representations. In our experience, we found that LLMs have enough general world knowledge that we can build lightweight signals on top of them, so we built this library to bring this concept to more developers.

This is a link to some tutorial content we wrote about how to use our library for LLM guardrailing. It turns out that LLM representations can make for more accurate guardrails than purpose-built guardrails like LlamaGuard, and this post shows you how!

We’re especially looking for feedback. This library is open-source: no ads, no logins, no telemetry (yet), all self-hosted for now.

My company, Krnel, is hoping to provide value-add services on top of an open core. Please reach out if you’re looking for advice or contracting engagements!

I'm getting it from the fact that you aren't showing people a job posting. Nor are you asking about their experience. Your application process is to send you ideas for growth. That is why it sounds like free consulting.

I know the kind of person you are looking for. I am that type of person. And I'm telling you there is no way I'd download an app and send my ideas in as part of a job application. I'd gladly do so as a small paid gig during the application process, when we have talked and it feels like my experience matches your needs. But not as the initial contact, no way.

Ah, but don't you know? Socialism is evil! Capitalism is GOD and is perfect!

- Republicans pretty much everywhere in the US

Seriously. This is pretty much why single-payer/universal healthcare systems aren't available in the US. It's also why UBI has never been tried. I'm sure someone is going to come in and say that I'm painting an overly-simplistic picture, but we seriously do have people still thinking that people willingly come to the US for healthcare because every other healthcare system is supposedly worse in every imaginable way (which somehow magically proves that what we have is better).

OpenAI is an existential threat to Google. They're both solving the same problem for consumers. Something like "there's information on the Internet that I want but don't know where it is". Almost all of Google's value derives from being the default solution to that problem. They can't give up that space to OpenAI. And, at least IMHO, it's obvious LLMs are the future in this area.

The other side to that coin is monetization. Google is dominant there as well. OpenAI can't yield that space to Google because it's how the value is extracted from the consumer.

> Can I transfer my Overwatch battlenet account to steam? I really want to jump ship too.

Seems like you can just keep using the Battle.net account on GNU/Linux. You just add the Battle.net installer as a "non-steam game" (bottom left of the games list). Then, you start it, add your account, install the game and it "just works". I used it on the steam deck to play D4 beta and D2R on my CachyOS desktop.

> How is Proton with nVidia drivers? I have a 3080.

My battle-hardened 1060GTX served me for years. I recently upgraded my whole rig from Debian + Intel + Nvidia to full AMD and the RX9070XT works very well, with the caveat that I had to switch to a newer kernel on CachyOS to support it. That was 4 months ago and the situation now should be resolved, so you can prob use any old normie distro.

Sync Conf is next week, and this sort of issue is so part of what I hope maybe can just go away. https://syncconf.dev/

Efforts like Electric SQL to have APIs/protocols for bulk fetching all changes (to a "table") is where it's at. https://electric-sql.com/docs/api/http

It's so rare for teams to do data loading well, rarer still we get effective caching, and often a products footing here only degrades with time. The various sync ideas out there offer such an alluring potential, of having a consistent way to get the client the updated live data they need, in a consistent fashion.

Side note, I'm also hoping the js / TC39 source phase imports proposal aka import source can help let large apps like NextCloud defer loading more of it's JS until needed too. But the waterfall you call out here seems like the real bad side (of NextCloud's architecture)! https://github.com/tc39/proposal-source-phase-imports

And then you have to wonder how many operations are done just to bill insurance companies money. I have injured my shoulder(here in the UK) and I saw a specialist shoulder surgeon who basically said that the state of the art research into these kinds of injuries is to just leave them alone and let them heal - but if you were in the US you would have had two operations on it already because they just love operating on things that don't need operating on for dubious medical benefit because they would charge 100k for each operation, easy.

As someone who used a lot of screens and was lonely in my youth, I can say with confidence that it was a response the family conflict in my home, not the creator of it. If my parents provided me a stable, non-abusive home, if they prioritized my emotional health and needs, I would've happily spent my time with them, not with randoms I found on the internet.

The only reason we have this broken system in the US is because of "lobbying" in an environment where unlimited money is "free speech". As long as these "insurance" companies continue to own the politicians, there will never be any meaningful progress. A 6% tax hike each year would induce riots in the streets, but somehow this same scenario in premiums is accepted by the population with anger and a shrug.

In the last two years, my mother had a tumour (successfully) removed from her brain and my sister had day-long heart surgery. Two extensive processes with lots of consults before and after, both requiring significant hospital stays. At the time I was a bit grumpy that I had to pay $15 a day for parking at the hospital, which was really the only out of pocket cost to the family here in Canada.

We do have a major shortage of GPs and wait times can be longer than you want, so I would not say that we necessarily have the best health care system in the world. But you really need to go to the cafeteria in a hospital to find cash registers. And when I picked up my mother from the hospital, we said goodbye to the nurses and just walked right out.

For EU citizens, GDPR requires that if you ask for it, a human has to review your case. (Article 22 "The data subject shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning him or her or similarly significantly affects him or her.")

I guess a lawyer can argue against this, but I'd say that losing access to a lifetime if mails is absolutely up there with "legal effects concerning him or her or similarly significantly affects him or her."

And from my own experience building software for government services, I can tell you this: In my experience in those systems it is not acceptable to just have a list where someone clicks “deny” all day. Or allow for that matter. We tried with a system were the rule is that the citizen gets <think they apply for> whenever all relevant demands are met. Legal was very clear: No automated decisions either way unless the relevant laws or regulations explicitly allow it, every case has to be reviewed independently — even when the outcome seems completely obvious to anyone who knows the field.

I have buried many pets, but last year my wife got cancer and while insurance was a huge headache, it came through in terms of protecting our wealth. She's currently in remission a year later after a very, very difficult fight that she nearly lost multiple times. It was extraordinarily stressful. I learned not to worry about the insurance crap, it all eventually worked itself out despite how frustrating it all was. So I'm not sure 9mm, 45, 357, or any other caliber for the "Hunter S. Thomson" solution, would have been a smart move for us. I totally understand the sentiment, because there are fates worse than death for sure.

What didn't hold up was not our insurance but my employer, who found a sneaky way to get rid of me and not have to deal with an employee who needed to dip out for his wife's numerous medical appointments.

Show HN: JotChain – Get more out of your daily work notes
by morozred | 2025-11-03 16:41:04+00:00
Hey HN,

I've been working in fast-paced startups for 10 years now, and I've noticed it's really hard to keep up with all the stuff I do. Sometimes it's tough to recall everything by the end of the week (EOW), and it's annoying when you have to show it off in a meeting or during a performance review.

I tried taking notes on paper, in Notion, Obsidian, Markdown files, and whatnot, but they all either got lost or I simply forgot to keep up with them.

That's why I decided to take action and build this small tool: JotChain. It lets you jot down quick notes throughout the day, then uses AI to turn them into polished summaries delivered via scheduled email notifications whenever you want them (e.g., right before your stand-up or weekly sync).

Here's how it works in a nutshell:

- Log wins, blockers, and context in a simple plain-text field (takes ~2 minutes, hit Cmd/Ctrl + Enter to save with optional tags).

- Set your cadence: daily, weekly, monthly, or custom, with timezone, lookback window, and lead time.

- Get AI-generated emails: Structured briefs with sections, key stats, and highlights (e.g., "Completed auth refactor, fixed 5 bugs, reviewed 12 PRs. Blocker: Database performance").

It turned out to be quite helpful for me, and I'm planning to introduce more features gradually to make building the habit even easier.

Free 14-day trial, no card needed. Plans start at $6/month or $36/year. Feel free to try it out and let me know what you think—what would make it better for your workflow?

There are some exciting (or terrifying depending on your perspective) developments in the “lab grown/cultivated” space. I had a chance to have some WildType salmon the other day. The costs are still way above wild caught or farmed salmon, but if they can get the price down and improve the texture I could see these cultivated meats really taking off.

Fun is good and all, if you enjoy it I won't argue. I enjoy a sunset myself from time to time. However most people are not enjoying in the moment. They want transportation only for the purposes of getting someplace so they can get something else done (or enjoy something else). Fun is good, but not everything is fun. I need to get home from work so I can get supper done in time for the evening activities (by coincidence I've been asked to make my homemade pretzels tonight - that takes 2 hours so I need to get home as soon as work is done)

I wasn't calling the descendants of the Mayans out for anything. I was specifically talking about the culture. Which is synonymous with the people in the upper class, which did ritual sacrifices of peasants.

the term Spaniards however targets the average people. Which are precisely farmers.

I do not see any double standard whatsoever, and frankly: you're brainwashed if you do.

--------

Hello, my name is Jesse.

I describe myself as a competent generalist, and a lifelong learner. I'm frequently working on something I've never done before. My most recent professional experience has been about a year at a semiconductor startup; I wrote prototypes for an ISA, compiler and a (really sweet) cycle simulator & debugger.

In terms of hard technical skills, I can quickly become productive in nearly any language, and at any level of the stack. I'm comfortable working in soft-realtime environments which are heavily multithreaded/async, and performance is a key acceptance criteria. I have a good understanding of modern hardware architectures, including GPUs, from main memory to registers and instruction pipelines. I have working knowledge of interpreters and dynamic language runtimes, including GCs. I'm convinced I can learn nearly anything (albeit some things more quickly than others), given an appropriate problem domain to apply it to.

In terms of business value, I can take hand-wavy visions of new products and turn them into working prototype(s), quickly. I'm comfortable refining those raw materials and delivering real value to customers, internal or external. I have a long track record of successfully identifying 80/20 solutions and love the feeling of making tools that make peoples lives better.

I'm a natural leader; informal teams coalesce around me when I'm not in a labelled position of leadership. I aspire to someday, maybe in the far future, become a strong technical leader. One of my best qualities is my (nearly) unwavering personal vendetta against mediocrity. I'm generally friendly and easy to get along with, but do not hesitate to volunteer constructive criticism where I see room for improvement. This has caused friction for me in the past, but I'm now generally good at gently steering my teammates in the direction of technical excellence.

In my personal life, I enjoy travelling, surfing, climbing, backcountry skiing, snowmobiling, pirates, and attending raves. I like the phrase "have strong opinions, weakly held".

If I was born to do one thing in this world, it's program computers.

Jesse

I this taste with most posts about Postgres that don’t come from “how we scaled Postgres to X”. It seems a lot of writers are trying to ride the wave of popularity, creating a ton of noise that can end up as tech debt for readers

The actual cost to treat "cancer or whatever" is extremely high in many cases. 15k a year to know you have that covered for a family isn't so bad given the true underlying cost.

A family member has a rare disease and I've gone through the details of the various treatments, how many people are involved in ongoing care and treatment etc. It's a lot of very well trained people spending a lot of time. A concrete treatment example - the process to create some blood plasma treatments is very complex, expensive etc. In the end, it will be millions of dollars of real underlying costs.

There is probably no cheap solution. Maybe GLP-1 type magic can put a real dent in the overall cost, but there will always be a desire to save people's lives even if the cost is very high.

It didn't age badly at all. This prediction was dead-on accurate. The widespread use of satellite monitoring of the Earth's surface has paid huge dividends for humanity in all sorts of ways including better and cheaper food production. Also the GPS system alone has been hugely important for every human system that involves navigating from one place on the Earth to another, which of course includes food transport as well as many many other things relevant to people's lives and health.

2. You definitively don't need an entire sysadmin team to run nextcloud, in my work (large organisation) there's three instances running (for different parts/purposes of which only one is run by more than one person, and I run myself both my personal instance and for a nonprofit with ~100 persons, it's really not much work after setup (and other systems are plenty of a lot more complicated systems to set up, trust me)

One requirement is to be willing to earn returns less than SP500.

Look up profit margins and annual returns for UNH, Elevance, CVS, Cigna, Humana, Centene, and Molina.

You have a billion laws to follow, you’re used as a punching bag by politicians and customers, have to get the price of your service approved by a government employee, and for all of that, you earn a 2% to 3% profit margin.

I think we are lost in translation here. I am not a native English speaker, so there may be a subtle implication in "trick" that you see and I don't.

I meant "trick" as in "trick of the trade", a clever/crafty way of achieving something that may not be obvious for less experienced individuals.

Re-phrasing my original comment for clarity: "Share buybacks are just a technique to lower WH tax, why do you see this as anything related to round tripping as related in this article?".

This is about these tools being blatantly flawed and unreliable.

In legal terms, marketing such a product is called "negligence" or "libel".

Lots of software is flawed and unreliable but this is typically addressed in the terms of service. This may not be possible with AI because the "liability" can extend well beyond just the user.

Why is that only an major issue in the US? we have to step back look at the purpose and functionality of an insurance to realise something is fundamentally off in the calculation (Like this post does the napkin maths for).

Corruption greed and blooming price gouging in a market devoid of regulation is to me the only thing that can make the situation this bad.

We already know insurance companies pay less than the out of pocket price, so why is the premium so high that paying out of pocket can even come close to beating insurance.
