I was really into VR in the beginning. My friend got the occulus DK1 and my mind was blown. I got a DK2 which ironically felt less immersive since the field of view was smaller but still very impressive.

I demoed it to a lot of my friends and everyone was very impressed but no one ever asked to go back. When I realized this knew there was a problem and that when I started doubting the adoption of VR.

Once Meta/Facebook bought occulus, I full checked out and never bought another VR head set ever again.

I still managed to make a VR version of one of my games before fully quitting. I don’t know what it would take for me to care about VR again.

This is very cool and I'm glad you were able to build it.

On the contrary though, I've been fascinated with simple non-technical solutions to problems lately. For example, my buddy hates it when people use his driveway to turn around. He lives on a corner lot and the layout is prone to people turning around in his driveway, and apparently this is a pet peeve of his. He was talking about installing a gate, or a retractable pole that he could extend from a hole in the driveway, all these intricate technological solutions, etc. I gave it some thought and got him a street cone off eBay to put in his driveway. I leveraged human psychology over technology and it worked like a charm and only cost $30.

For your example, I would just put a do not disturb sign on the door. The flip around kind they have at hotels. It takes getting up, but just as effective and you get a few steps in. Of course you don't get to learn and build stuff, but like I said, I'm fascinated by simple solutions right now.

It's weird that people dying is an effective way of moving knowledge forward. Intuitively, you'd think the longer people live the more they can learn and retain.

Perhaps I am unimaginative about whatever AGI might be, but it so often feels to me like predictions are more based on sci-fi than observation. The theorized AI is some anthropomorphization of a 1960s mainframe: you tell it what to do and it executes that exactly with precise logic and no understanding of nuance or ambiguity. Maybe it is evil. The SOTA in AI at the moment is very good at nuance and ambiguity but sometimes does things that are nonsensical. I think there should be less planning around something super-logical.

I don't think that it's possible to really know. I've never had a potential employer tell me why they chose not to hire me. That said, I don't think they've had a significant impact.

But I don't leave time unaccounted for, either. I include the gap times in my resume by explaining what I have done during them that would relate to the position (hobby projects, volunteering, etc.) My resume is a report of my experience, but that doesn't have to be limited to experience that I've been paid for.

> the final emergent property of energy gradients 100% leads to pure logic machines.

Energy comes from gradients, so I think you used one derivative too many!

Either you should say:

"the final emergent property of energy 100% leads to pure logic machines"

Or if you want to sound smart:

"the final emergent property of physical quantity gradients 100% leads to pure logic machines"

I would absolutely buy one if it was about half the price. I can think of lots of uses for it.

My kids love our Quest 3. It’s a great system for gaming. They’ve clocked hundreds of hours playing Beat Saber and Gorilla Tag.

If Apple can lower the price significantly and make it more comfortable I think there is potential for this to be a successful product.

And when you’re at a smaller company 90% of your time is fighting societal complexity, limit of which also approaches infinity, but at a steeper angle.

No greater Scott’s man can tell you that the reality is surprisingly complex, and sometimes you have resources to organize and fight them, and sometimes you use those resources wiser than the other group of people, and can share the lessons. Sometimes, you just have no idea if your lesson is even useful. Let’s judge the story on its merits and learn what we can from it.

BART crime is up over the past decade. People don't avoid BART because of that headline with the chainsaw man. They avoid it because of everyday crime and violence.

I'm sure it's similar for many other metro transport options in the USA. California in particular has a rough go for many reasons.

It doesn't even have to be something bad or happen to you. One "my buddy had his bike stolen off the light rail" and several people will be turned off of ever trying to use it.

The linked Musk comment where a minor political leader is singing kill the white farmers:

https://www.businesslive.co.za/bd/national/2024-05-30-julius...

Supreme court ruled that it was not hate speech.

In context, south africa has been expropriating land from white owners due to historical racist inequalities. There's a great deal of tensions on the subject.

Statistically, there is significant violence against white farmers in South Africa. However, the counter to genocide is that the country's overall murder rate is among the highest in the world. The problem is because there's so many white farmers that it's skewing the data?

South Africa during no war has a murder rate of 45 deaths per 100,000 per year. One of the worsts in the world.

The Gaza war since 2023 has roughly a ~20 deaths per 100,000 per year.

Ukraine war is roughly ~25 deaths per 100,000 per year.

My unpopular opinion:

The government isnt the one committing the genocide. The courts failed to punish this political leader's hate speech and stochastic terrorism, leading to genocide of white farmers.

Your original comment argued there is no value add. I gave an example of the kind of value add that you can get (saving money/time on following up something wrong).

I did not advocate for this specific release being better, and I certainly did not say we should "move fast and break things". I don't know who you think you're arguing against but it's not me.

I only pushed back on the specific idea that this there is no possible value-add by this kind of software.
Show HN: A free AI risk assessment tool for LLM applications
by percyding99 | 2025-05-15 12:50:43+00:00
We’ve built an AI risk assessment tool designed specifically for GenAI/LLM applications. It's still early, but we’d love your feedback. Here’s what it does:

1. it performs comprehensive AI risk assessments by analyzing your codebase against different AI regulation/framework or even internal policies. It identifies potential issues and suggests fixes directly through one click PRs.

2. the first framework the platform supports is OWASP Top 10 for LLM Applications 2025, upcoming framework will be ISO 42001 as well as custom policy documents.

3. we're a small, early stage team, so the free tier offers 5 assessments per user. If you need more, just reach out, happy to help.

4. sign in via github is required. We request read access to scan code and write access to open PRs for fix suggestions.

5. we are looking for design partners to collaborate with us. If you are looking to build compliance-by-design AI products, we'd love to chat.

product url: https://www.gettavo.com/app

we'd really appreciate feedback on:

- what you like

- what you don't like

- what do you want to see for the next major feature

- bugs

- any other feedback

Yes, but its not just startups and people do not seem to actually resolve it.

Lots of big businesses use recaptcha. Quite often unnecessarily. If I need to login with 2FA touse a service does it really need recaptcha?

Similarly, cloudflare sends you emails telling you how many bots and attacks it has stopped - but you do not know how many false positives there were.

Why keep pursuing it if you don't like it in general?

I don't like coffee. I've tried most of the variations over the years, and don't like any of them. So I don't drink it.

The top comment and tons of others are people trying to work around what for many is simply a general dislike of coffee. Good beans, clean water, certain temperature. That's not going to change somebody who doesn't like the taste of coffee.

I just drink water. It's all we need.

Ironically, working with a junior dev is a lot like this -- setting them on a task, then coming back later with dogs and flashlights to retrieve them from the deep woods they've inevitably lost themselves in by just forging ahead, making assumptions, and asking no questions.

True! But I think that movies adapted for TV must be made for the average "good quality" screen, not the state of the art that almost nobody owns. At least they should look decent enough in a good quality (but not top-notch) setup.

Also, the YouTube video I'm thinking of singles out Wicked as seen in movie theaters. The image "as intended" looks washed out and without contrast.

> where someone loads up a cart with merchandise and rolls it out the door

There's 2 different things here, though. There's casual shoplifting, and there are organized gangs of shoplifters. What you're describing is organized gangs of shoplifting, and that's not cause by a corrosion in the fabric of society, that's caused because these gangs know that retailers aren't interested in stopping them.

A random person might steal an item or two, but a random person isn't going to load up a cart with merchandise and walk out the door. But organized crime will happily take advantage of retailers who won't do anything about them.

Eh. If this were possible, transport system operators would jump on it. Availability of bus drivers is the main operational constraint on many systems.

However, it's really very far from being a practical reality; driving a bus is much more difficult than driving a car, and the consequences if you screw up can be far, far worse. Buses are very big and dangerous.

There is the big one - OEMs have to meet mandated emissions regulations and governments check (see VW). Aftermarket legally has to meet the same regulations, but in practice (at least so far) they mostly have not been checked, and if they are checked it is only after they have sold something and got it installed on a car, while OEMs get checked before they sell anything. Which is to say aftermarket is generally just trading power/fuel efficiency (often both) for worse emissions.

Bah, clickbait.

It's a $3500 VR headset, so a niche bit of kit from the jump. Nobody's made this work in a meaningful way, and the initial reviews of the Vision Pro made it clear this was no different (though there were kinds words about Apple's implementation of this level of tech).

Another commenter notes that it's beautiful, does what it does well, but there's little to do with it. That's utterly true. Maybe in a few years, that'll be different, but I think the real problem is that Apple brought it to market before the rest of the market was ready to jump forward. It's too expensive for the level of mass adoption that would jumpstart a VR software ecosystem (ie, in the same way the iPhone catalyzed phone apps).

At least sometimes. I do not know about AI scraping but there are plenty of scraping solutions that do run JS.

It also puts of some genuine users like me who prefer to keep JS off.

The 97% is only accurate if you assume a zero false positive rate.

I'm not sure which paradoxes you are referring to. Type systems are used for a lot of things, in Mycelium a Type is an encoding strategy for it's Values. And just like I could explain the encoding strategy to you in text, the Type can be stored as bits representing that strategy, so a machine can read the Type and know how to decode Values using the strategy. Eventually this ends with predefined constants at the Type of a Type of a Value level, so there's a fixed point instead of an infinity.

To be fair, old Entity Framework was on the heavier side. Still much faster than e.g. ActiveRecord but enough for Dapper to be made back then. The gap between them is mostly gone nowadays plus .NET itself has become massively faster and alternate more efficient alternatives got introduced since (Dapper AOT, its main goal is NAOT compatibility but it also uses the opportunity to further streamline the implementation).

>I dunno, I think Google Glass if released today would do significantly better.

Why? Its users would still be called "glassholes" just like before. Nobody likes looking stupid in public, and wearing AR ski/diving goggles in public makes you look like a complete tool.

Then there's the issue with privacy. People wouldn't want to be constantly filmed/scanned in public by other people's AR goggles. It would be like wherever you go people having their smartphones pointed at you.

Apple VP is a niche solution looking for a niche problem. It's no iPhone moment.

> public transport is so utterly utterly awful and unreliable and slow and dirty and just terrible in London.

Completely disagree with this statement. Living in London for 4 years now and despite the occasional late train or "ghost" bus it is quite reliable and at reasonable speeds. Unsure what you mean about "dirty", the buses and tube rarely seem messy.

However I agree that the toll should be higher and applicable to all private vehicles.

Besides GeoCities - the rest are being relaunched by SV VCs and PE groups.

Napster was acquired and relaunched in crypto a few years ago and just resold for $100M+ to a metaverse company immediately following a new raise at a $1B+ valuation.

So yeah it’s acquiring historic IP by VC/PE to resell to friends that are using someone else’s funds. Considering the .com boom and era of publicly traded big tech giving golden parachutes to friends (buying their companies and shutting them down) - it’s very nostalgic.

I bought the base model shortly after launch. It went from the coolest piece of tech I had ever handled to in a drawer untouched for at least a couple weeks. It probably would have mostly stayed there or been sold on eBay, until... right at a year ago I was in stopped traffic and hit by a distracted driver at highway speeds. Two broken hands, fractured sternum, head injury with vision issues, life changed in an instant. Fast forward a few weeks - hurt, bored, unable to use a computer comfortably I started using it to mirror my Mac with a lap desk & a Magic Keyboard/trackpad. It was a godsend, I was able to comfortably use my computer, communicate, watch TV, etc. Now, today, I'm mostly recovered, but I still use my VP daily, when not in meetings it's my preferred interface to my Mac, working without it feels like I'm missing a critical piece of the interface.
Ask HN: How to test data generation for complex B2B SaaS?
by thenaturalist | 2025-05-15 12:58:28+00:00
Hi there, I am tasked with building an analytics stack for a B2B white-label data integration & modelling SaaS where accuracy is of very high importance.

We're looking at ca. 15 disinct sources with ca. 50-60 tables.

I am told I am unable to use production data for staging/ development purposes due to GDPR. Hearing this, I am scratching my head and looking at a mountain to climb just to get back to being able to model outside of prod.

What are your tools or experiences for building reliable dummy data at scale?

The decline public transportation, in my view, reflects a shift in priorities within the Democratic Party. Back in the 1990s, Democrats were more focused on tangible public services—things like infrastructure, roads, transit systems. Today, the emphasis seems to have moved toward issues like environmental policy, DEI, and gender identity.

As someone who’s deeply frustrated by the lack of progress on projects like high-speed rail between SF and LA, completing the BART loop around the Bay, improving public schools in San Francisco, and addressing homelessness, I find it maddening. These are real, urgent issues, and yet they often seem sidelined.

Of course, Republicans generally oppose these kinds of initiatives altogether.

Trying to push for change within the Democratic Party has been incredibly difficult for me. It often feels like the space is dominated by highly educated, well spoken, intellectually confident people (far more so than myself) which can make it hard to even participate, let alone influence policy.

So I just think: screw it, I’m a Republican now. And that is not going to make public transport any better.

So this is why…

The language of reward mechanism can be translated to language of emotions. Emotions is something humans experience and understand on innate level, they are qualia. If a reward structure is translated to our language we can get a better intuitive understanding.

E.g. a direct negative reward associated with undesired states is often called "pain". E.g. if you want robot to avoid bumping into walls you give it a "pain" feedback and then it would learn to avoid walls. That's exactly how it works for humans, animals, etc. Obviously robot does not literally experience "pain" as an emotion, it's just a reward structure.

I would add another metric: how are businesses doing since the change? I was walking around the city on a Wednesday evening and it was utterly eerie how empty it felt. This past weekend seemed to be the exact opposite thanks to the nice weather, but I haven't seen that level of emptiness.

I notice empty storefronts and anecdotally, I feel like there is an increasing number. I have a friend who opened a store downtown just before this happened. I don't dare ask yet, but I can't see it being a benefit for small businesses.

When you know where everything is and will be, sure; the hard parts are (1) actually spotting the obstacles, and (2) predicting how they will move far enough in advance to avoid collisions.

(1) is why Mark Rober's recent viral video had the funny ending (https://www.youtube.com/shorts/U1MigIJXJx8) and also why there's so many less funny endings in news stories (https://www.independent.co.uk/news/world/americas/tesla-elon...)

Can't speak about Prisma (or Postgres much).

But I've found with that you can get better performance in _few_ situations with application level joins than SQL joins when the SQL join is causing a table lock and therefore rather than slower parallel application joins you have sequential MySQL joins. (The lock also prevents other parallel DB queries which is generally the bigger deal than if this endpoint is faster or not).

Although I do reach for the SQL join first but if something is slow then metrics and optimization is necessary.

This means it's no longer safe to point to github-hosted repos in `git:` or `github:` dependencies in ruby bundler, yes?

I forget because I don't use them, but weren't there some products meant as dependency package repositories that github had introduced at some point, for some platforms? Does this apply to them? (I would hope not unless they want to kill them?)

This rather enormously changes github's potential place in ecosystems.

What with the poor announcement/rollout -- also unusual for what we expect of github, if they had realized how much this effects -- I wonder if this was an "emergency" thing not fully thought out in response to the crazy decentralized bot deluge we've all been dealing with. I wonder if they will reconsider and come up with another solution -- this one and the way it was rolled out do not really match the ingenuity and competence we usually count on from github.

I think it will hurt github's reputation more than they realize if they don't provide a lot more context, with suggested workarounds for various use cases, and/or a rollback. This is actually quite an impactful change, in a way that the subtle rollout seems to suggest they didn't realize?
by sgarland | 2025-05-15 13:01:35+00:00
Yes, global read replicas can be helpful, though the replica lag needs to be thoughtfully considered.

IMO, one of the worst offenders is places with microservices, who absolutely do not need microservices, and are doing reads-after-writes.

For every RDBMS I know of other than MySQL (even MariaDB has this), you can tack a RETURNING clause onto the write, and get the entire row back. This shouldn’t be necessary for most cases anyway, because by definition, you have (almost) all of the row data already. The only times you wouldn’t is DB-generated values like an auto-incrementing ID, UUID from the DB, or a timestamp from the DB. MySQL can actually handle the first case; the cursor holds LAST_INSERT_ID. So if you had a monolith, it’s trivial to pass what you wrote to the next function that needs it – boom, no concern about stale data, and one fewer DB round trip.

Even with separate services, this is still possible, though somewhat slower, but I’ve not seen anyone do it.
by crowcroft | 2025-05-15 13:02:07+00:00
Why does Postgres get so much love, and MySQL/MariaDB get nothing?

I'm assuming it's largely because Postgres has more momentum, and is much more extensible, but if you're just trying to do 'boring DB stuff' I find it's faster for most use cases. Development has slowed, but it would be hard to argue that it's not battle tested and robust.
