Such a miss not having good full-color AR included. I’m a VR enthusiast with a Meta Quest 3, and it’s a shame that this headset is better than the Quest in every way except the most important one.

In my opinion, VR gaming never becomes more than a gimmick. It adds a questionable improvement in graphics and immersion at the incredibly high cost of excluding yourself from the real world. Right now it’s not worth it, and I don’t think it ever will be, no matter how good the graphics get. That’s assuming they even solve the motion sickness problem, which doesn’t seem solvable to me at this point.

The motion controls in VR will also always be severely limited by the fact that you can’t see your surroundings. You can’t meaningfully move around or swing your arms fast in any realistic home environment when you’re in full VR. You’re constantly at risk of punching something or breaking something, or both. So the controls have to become really stiff and avoid requiring wide movement, at which point you might as well just push buttons on a gamepad.

But AR is a completely different thing. No motion sickness, no risk in any movement, you can move around without silly threadmills, and no exclusion from the world. It’s truly amazing. The AR boxing, pickleball, ping pong and golf are so much closer to real thing then to a videogame adaptation, even the shitty Quest graphics don't ruin the magic. Those AR experiences don't work on videogame rules and really deserve their own name and category - they're as different from gaming as books are from movies. If VR headsets don’t die out, AR is going to be the thing that brings them to the mainstream. I just wish it had more attention, more apps, and more non-Meta mainstream platforms. Not this time, sadly.

archive.

I have partial/spotty archives going back to the early 90s, which then turn into a full archive starting in 2004. It's not often but there are plenty of times where it's been useful to be able to dig up some nugget from 20-30 years ago to answer a question. And also, sometimes it's just fun to go on a nostalgia trip

If this were the case nobody would ever offer file hosting services (eg. Google Drive). Do you have any case history to show any company getting prosecuted for unknowingly hosting encrypted blobs of illegal material?

Obviously if they have to ability to know material is illegal, that's a problem.

And exactly what algorithm can you provide to me that takes an encrypted blob as an input and returns whether it is not illegal material. Clearly that doesn't exist, so your point makes zero sense.

You may be conflating "I forgot the key" vs "I've never been provided the key"
Show HN: ChatExport Structurer – parse ChatGPT/Claude exports into queryable SQL
by chan1 | 2025-11-12 20:59:56+00:00
I wanted to query my own chat history but the JSON exports were a mess to work with. Built a small parser that turns them into clean SQL databases. Parsed 70k+ messages across multiple models. Useful for analyzing chat history, building a personal knowledge base, or archiving conversations. Simple CLI, open source.

My work devices don't have much on them, mostly corporate asset tags and the like. My own, though, I make my own. The stickers reflect things I like or find amusing; maybe they'll get a smirk or a chuckle from someone else, maybe not.

In the end, they're like the tattoos that someone else commented on. (I have those as well.) If you appreciate them, great! If you don't like them, that's fine too. Fundamentally, they're not for you.

My inbox's default retention policy deletes anything that is more than 90 days old unless it has a tag. Receipts, billing statements, messages from real people that I added to my contacts etc all get tagged and retained. Your newsletters, the OTPs, the appointment reminders all fall into the abyss.

But I personally do not like email as a system of record. My response to 'what if I need to know something about the tires' is that I keep a spreadsheet with everything I do to my car.

I avoided Blazor, despite multiple people on my teams pushing for it. It always felt like it fit in the same space as web forms and silverlight. A product created to fill a gap of developers that wrote desktop apps and don't want to learn how to write front end code for the web. Plus it binds you to the product lifecycle of a .net side project that likely will be abandoned.

While Blazor has some cool stuff built in, the cool stuff never felt worth the risk of building a product around it.

Here in Argentina the law says they must be rounded down. Initially it was for 5 AR$cents, and some shops still has the oficial sign that says AR$ 0.05.

We unofficially drop the coins/bills when the reach ~US$0.03, so now we dropped the AR$50 bills and everythig in cash is rounded down to AR$100 (US$0.07).

(The only exception is the photocopy shop 2 blocks away from home.)

Credit cards are charged the exact ammount, with cents that are irrelevant.

> It feels like it wouldn't be good value at a higher price, I don't know if I'd buy it for more than that myself.

That's because you're a cheap skate hacker. $10 is the minimum price you should put. People who think $10 is too expensive are also going to think that $1 or 1c is too expensive.
Ask HN: Wouldn't it be much easier if you compress all env vars into one?
by crowdyriver | 2025-11-12 21:02:01+00:00
In most apps I develop, there's at most 3 groups of environments, local - staging - prod.

Wouldn't it be easier to just join all env vars needed for each environment into a base64 encoded env var, and then just pass that into the given app?

I feel like there should be less room for error, and it's easy to add new services. There wouldn't be need for cloud vendors like vercel to namespace env vars, you would be already doing it yourself.

Yeah, maybe a small cli utility to generate those envs would be cool, but it looks like that wouldn't introduce much friction.

I can't be the first one to think about this, has this been tried?

Thanks for your input!

Edit: clarity

First of all, while I hear about that protest first time, I'm 99% sure that they were not fines for driving under speed limit, but because of the unreasonable obstruction of the left lanes. This is prohibited probably in all countries, regardless of the limits in use.

Second, it is a widely known issue, that a slower mowing car is causing ripple-like delays far from the car itself. For example when a police car is driving inside the traffic flow. But if most of the cars are following the rules, like 95% of them, then one law abiding Waymo would fit just fine. In EU, with the deluge of speed traps and mobile patrols, most of the cars are driving under the limit, and honestly it feels fine. I'm originally from a country where +20 above was like a norm, and fast cars were +40 or more, so adjusting to EU took some effort. But now I don't even feel the need to speed, especially if it is 140km/h highway (86 m/h)

The real trick is not over complicating things. The goal is to have high fidelity rendering where the eye is currently focusing so to solve for saccades you just build a small buffer area around the idealized minimum high res center and the saccades will safely stay inside that area within the ability of the system to react to the larger overall movements.

Picture demonstrating the large area that foveated rendering actually covers as high or mid res: https://www.reddit.com/r/oculus/comments/66nfap/made_a_pic_t...

That seems weird. I mean, if you decide to abolish the penny, you just do it cold turkey. You don't set a date in the future and the continue making them, so that the last penny is accompanied by fanfare.

> Trump announced via social media in February that he instructed the Mint to stop making the once-popular coin, citing the cost of production.

So between February and today, they just ignored the order?

What justified the pennies produced between February and November? Those pennies were necessary, and still cost-effective, but going forward, the penny as such is no longer necessary?

Removing regulations 20 years ago when people were screaming that we need to would have helped. 20 years ago nuclear was still the best answer, but since it wasn't allowed we didn't build it (instead mostly coal and gas). Power companies are good at planning, and AI/data centers are not using that much more power than predicted 5 years ago - but the regulations have to allow for plans.

Removing regulations today will have an effect in 10-20 years. I cannot give you a quick answer to the problem.

I think people underestimate how many stores used to set prices to avoid pennies. When I was a kid it was frequent. Goose the price so cost + tax rounded to the nearest nickel. But now everything is 23.99 or sometimes 23.95, and they use the pennies place to denote clearance items. Like 19.94 or 3.98.

Oof, I think that you are right. The issue with Futurelock is a failure of liveness, where the Future holding the lock doesn't get polled. tokio::join! would keep it alive and therefore my suggestion would mistakenly panic.

Yeah, the true fix is probably some form of the fabled Linear types/Structured concurrency where you can guarantee liveness properties.

Does open culture mean free? Are you willing to work for free? It is perfectly OK to sell goods in exchange for money, which is what NYT is doing.

I dont know why you're so upset with it. You cant walk into Apple Store and except to walk away with a free iPhone. Then why are you expecting to "walk" into nytimes' website and walk away with free article?

In other words, allow higher exposure to ratiation?

Does not sound too great and obvious to me to be honest and it seems debated in the scientific community.

So irrational fear of radiation is surely a thing and maybe the models as to when real danger starts can be updated, but I would not call that question obvious when the experts debate it and I ain't one.

I would agree, but I'm a bit sad about the resolution. I either want a mediocre resolution for cheap, or a can-do-it-all machine with great resolution for more money. I'm fearful that because of its great computing specs it's going to be expensive, but it's not going to be good enough for me visually to be used a lot.

I mean, I have a Quest 2 and it'd be a step up but not a huge one. I've seen the Apple Vision and that did wow me. The vision is just in a weird corner inside a closed ecosystem and a tech demo for apple. No thanks. Valve will absolutely do that ten times better. But will it be visually so much better than a quest 2? I doubt it.

A 700 MHz Crusoe TM5400 delivered roughly the same performance as a 500 MHz Pentium III on SPEC benchmarks.

Transmeta as a startup (the pitch to early investors) went after high performance and maybe that could be construed as DC could beat OOO. But the released product pivoted (like that hasn't happened before) to low power, hence the name Efficeon. Its killer app was playing a DVD on a laptop on a cross country flight without running out of battery and without frying your own laptop. They basically invented that market which then gave them the great good pleasure of competing with Intel.

It was a heroic doomed effort. Brought to its attention, Intel quickly adapted to that market. Game, set, match. Ditzel became a VP at Intel.

I don't blieve that OpenAI, or any American corporation, has the wherewithal to actually maintain _your_ privacy in the face of _their_ profitability.

You copied my material without my permission. I've been harmed. That right is independent of pricing. Otherwise Napster would never have generated legal cases.

I'm using claws-mail and currently have 53,399 mails in my INBOX and 62,138 mails in my spam folder. I've got a few other mailboxes for mailing lists, some of them 100k entries but I barely read them. I guess I could delete these but my mail folder is only 19.2 GB in size. The storage medium sizes increase so fast that I've never had to delete anything.

A little less than 25 years ago, my then-new day job wanted me to build them a new mail server, using Linux.

I'd put together one or two public-facing mail servers before, but it'd been a few years and the landscape had changed (postfix was the new hotness, sendmail was old news, etc). And I had a FreeBSD machine at home that I'd previously built from garbage that I was using for NAT and a few other things.

So, wanting to appear all slick and stuff at the new job, I built a prototype at home on that FreeBSD box using a freebie dyndns subdomain (which was still practical at that time).

It all worked great. For a couple of years I even used it to host my own email at home. It was less trouble to maintain than the Linux-based thing I'd built at work even though they both started with the same software configs.

But that FreeBSD box was only ever a little forgettable trash-built machine, so there were no backups at all when the hard drive crashed completely (there were grooves worn into the platters) while I was out of town.

Which might normally be the end of the story, but: FreeBSD kept rolling just fine. Whatever data was in RAM (which apparently included at least sshd and bash) remained in RAM and stayed usable, and it kept routing packets like nothing had ever happened at all.

I marveled at this for a few weeks as this very broken machine kept flawlessly doing its NAT duties and providing solid Internet access for my LAN until I scrounged up enough pennies to buy my first "home router": A Linksys WRT54GS. (That little hackable Linux box was a very fun introduction to the rabbit hole of using hardware in unintended ways, but that's a story for a different comment section.)

That brings you back to managing memory though, C++/CLI having access to managed C# handles/references for GC'd objects (and finalization) would greatly simplify any memory management at the same time as having first class access to native libaries.

Granted, one could probably build some of the machinery memory management in a simple way but it'd still need to be done and probably not be coherent with other native interfaces.

Defeating Nondeterminism in LLM Inference

> As it turns out, our request’s output does depend on the parallel user requests. Not because we’re somehow leaking information across batches — instead, it’s because our forward pass lacks “batch invariance”, causing our request’s output to depend on the batch size of our forward pass.

tl;dr: the way inference is batched introduces non-determinism.

If you want a different anecdote, I have a LG C1 that got burn in after a year of use, playing FFXIV. I can see a blue outline of where my minimap and hotbars are. HUD burn-in. The only thing I disabled was the dimming feature, because it's outright annoying to use, where every time i'd scroll it'd make the text on a page illegiblly dark. (Dark mode pages, white text becomes dark gray while scrolling then back to white when stopped... sometimes not!). I moved that TV to the living room and got a non oled samsung instead which is what I use now.

Hi

I'm building a tool called ArchitectGBT — it helps developers and founders pick the best AI models for their projects in 60 seconds, with cost breakdowns and starter templates.

I've personally wasted hours, on trial-and-error choosing models, often ending up overspending or getting subpar results. I'm curious—how many of you have lost money or time because of bad model choices? Would love to hear your stories.

If you’re interested in testing something that could prevent this, join the waitlist:

Thanks!

I have a quest 2 where the passthrough is laughable. Would you really use it for anything other than getting a glimpse of the outside world? I sure don't, but that may be because of the shitty camera's. But I never saw the appeal of passthrough anyways, isn't the point of a VR headset to see a different reality? Like, not the real world?

> I'm waiting for the other shoe to drop when it comes to GLP-1s

We know there are downsides. They’re just irrelevant compared to being obese. (Or alcoholic. Or, potentially, overweight.)

It might be a vitamin, where there literally aren’t any downsides. I’m sceptical of that. But to the degree there is mass cognitive bias in respect of GLP-1s, it’s against them. (I suspect these are sour grapes due to the drugs being unreachable for many.)

My frank concern is we’re separating into a social media addicted, unvaccinated and obese population on one hand and a wealthy, insured, disease free and fit one on the other. Those are dangerous class and physical divides to risk becoming heritable (socially, not genetically).

Sound masking systems still use 70V audio output with output transformers at each speaker, voltage drop is rough when your signal is only a few volts and you’re using small conductors. Last time I sold a sound masking install we used 14/2 cable for the 70V audio signal.

It really is so sad to see people get sucked into the alt-right pipeline and not even realize it despite it being so obvious from the outside that it's happening. For all his talk on indoctrination it's weird to suddenly have very specific opinions on a bunch of unrelated topics you have no personal involvement in, no expertise in, and tangible connection to. Even if you have feeling about some of these issues in passing no normal person with a dayjob becomes so prolific about all of them at once.

Except, of course, that despite these issues not moving the needle on basically anything in daily life they are all connected as part of a grand conspiracy corrupt society in some nonspecific way and must be eradicated. In a way I really can't blame any individual because there's very little in the way of defenses against it but it's sad to see the cocktail of intelligence, arrogance, and fame mean that no one will ever be successful at pulling him out.

It used to take me 50 minutes to go 11 miles on 101/110 from studio city to downtown LA, so 20mph seems optimistic.

Heck, it wasn't even all that rare for it to take me 45 minutes to go 5 miles on 101 from Rengstorff Ave to Willow Rd in the Bay Area in 6pm rush hour just because of the exit.

It even once took me 2h to make it from Candlestick Park to the 101 after an NFL game.

So yeah, maybe 2 hours for a few miles isn't quite right, but I've experienced daily counterexamples to your 20mph number too.

The rule in Indiana is that on a multilane highway you must move to the right to allow overtaking traffic to pass.

That's a rule just about everywhere, but that's not what's being discussed. I'm in the right lane doing the speed limit, and OP claims that's "technically" illegal due to contradictory laws. (Where there is no real contradiction, because the Chesterton's Fence is that we don't want Farmer Jones driving his tractor to his fields down I-75 through Atlanta.)

It almost doesn't matter. There's three choices for spinning drives and all storage devices fail (even SSDs), and you need a plan for that. There's variance in failure rates and warranty periods, but most (new) drives last the warranty period, and used drives is more complex than just manufacturer --- how were they used, stored, and handled before resale probably makes more difference than who made them.

IMHO, it's more important to consider correlated failures rather than worry about getting the best or avoiding the worst drives. Try to avoid running an array that's built from same model, same firmware, same build time, same power on hours, same workload. Every so often, you get things like drive disappears when power on time overflows, or a manufacturing error that makes most drives fail after N weeks of use, having all of your drives in the same part of their lifecycle makes you more likely to experience a catastrophic failure that failure rate analysis wouldn't pick up.

Picking SSDs carefully bears more fruit, there are many more makers and wider variance in performance and reliability as well as characteristics during failure: everyone says SSDs go read only during failure, but my experience has been that lots of SSDs disappear from their interfaces during failure; you might reasonably have less redundancy if you have confidence the SSD will remain readable for recovery if it fails.

What GP talks about is illustrated with the following modification of your example:

PS /home/user> gc *.txt | measure | cat | select -ExpandProperty Count Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found. Select-Object: Property "Count" cannot be found.

Essentially at every step you need to consider whether the preceding command outputs objects or not. This isn't the case with the Unix way. The pipeline always carries a stream of bytes. You only have to consider how to interpret that stream.

Here's what I don't understand.

Developers who get excited by agentic development put out posts like this. (I get excited too.)

Other developers tend to point out objections in terms of maintainability, scalability, overly complicated solutions, and so on. All of which are valid.

However, this part of AI evolves very quickly. So given these are known problems, why shouldn't we expect rapid improvements in agentic AI systems for software development, to the point where software developers who stick with the old paradigm will indeed be eroded in time? I'm genuinely curious because clearly the speed of advancement is significant.
