I think people are working off of outdated information. I have a 2020 Model 3 and it's been fine in subzero temperatures. Yes, range goes down by about 20%, but if anything it's more convenient than a gas car in the cold because you don't have to wait for an engine to heat up before the cabin gets warm. Also you always wake up with a full tank (so to speak) because you don't need to go to a gas station to refill. And EVs tend to be AWD, so they're easy to drive in the winter. During one snowstorm I had to help dig out trucks that got stuck, but my car was fine.

Newer models have heat pumps that greatly improve efficiency in cold weather. They also have better battery chemistries that store more energy in the same form factor. Unless you live in a very remote, very cold location (eg: rural Alaska), an EV is a fine choice.

The "solid" frame titanium glasses I'm wearing right now are 0.5mm thick. If you were to put a housing the same thickness around a 60x10mm cylinder you've got something about the weight of an acetate frame, with zero electronics inside. Add the electronics and you've got something heavier, just with titanium as the material.

I mean, the material is nice, but you're not making it light weight that way.

Curious to see how this goes. It seems to me it’s hard to match reality—for example, books, book shelves, pencils, drafting tables, gizmos, keyboards, mouse, etc. Things with tactile feedback. Leafing through a book typeset on nice paper will always be a better experience than the best of digital representations.

AR will always be somewhat awkward until you can physically touch and interact with the material things. It’s useful, sure, but not a replacement.

Haptic feedback is probably my favorite iPhone user experience improvement on both the hardware and software side.

However, I will never be able to type faster than on my keyboard, and even with the most advanced voice inputs, I will always be able to type longer and with less fatigue than if I were to use my voice—having ten fingers and one set of vocal cords.

All options are going to be valid and useful for a very long time.

I don't know about vibe coding (I'm not a fan of vibe coding) but LLM agents make me more likely to use good libraries, not less, because they instantly know how to use them; there's less intellectual friction to breaking them out (don't have to find and add the dep, don't have to look for the example code). These kinds of things made me ultra-likely to just hand-code crappier versions of stuff libraries did, before I got LLM-assisted.

Look, we can talk about how the political views of Democrats and Republicans shook out over the last 15 years but trying to dispute that the Tea Party was founded and fueled by an intense racism laser focused on Barack & Michelle Obama is like trying to argue the Civil War wasn't over slavery. This wasn't some liberal media spin, this was straight out of the mouths of prominent conservatives posting on their own websites and ranting on their own talk shows.

I was fascinated by these people in the '08-'12 era. I watched so much Fox News, listended to Sean Hannity and Rush Limbaugh, and kept up with Breitbart and The Drudge Report. I got so many free civics papers from my weird obsession. They were racist as hell. I saw it with my own eyes and heard it with my own ears. And it's not like it was just talking heads, conservative online spaces were worse.

Apparently in mines they are sometimes extinguished with nitrogen. For less contained ones, injecting water or mud, while trying to seal off the ground with impermeable clay to halt oxygen and hopefully choke the fumes. Their scope can be huge though, and they generate a lot of energy which can cause subsidence to open up new passages. The Centralia fire in the US is apparently 15km².

”Dunning-Kruger effect leads us to understimate the complexity of the problem solved by the library we're considering.”

Invoking the smarter-than-thou effect is not a great starting point.

See e.g. https://www.sciencedirect.com/science/article/abs/pii/S01602...

If we’re considering a library, it would be prudent of us to take a look at the source code to see what exactly we’re pulling in. In the process, we would learn about the lay of the land, the API and the internals, and get at least an overview of the complexity of the problem it solves.

IIRC, Slack backed out of their DNSSEC deployment because of a bug with wildcards and NSEC records (in Route53, not Slack), but the problem Slack subsequently experienced was not caused by that bug, but was instead caused by the boneheaded way in which Slack tried to back out of DNSSEC. I.e. Slack’s problem was entirely their own doing, and completely avoidable if they had had any idea of what they were doing.

How big a deal is this? I'm not familiar with Verizon as an ISP, like Comcast. Does Verizon have lots of Fios customers?

The other question is: how do all Fios services go down at once? Verizon used to be a baby bell roll-up. The Bell System was not centralized. Failure of one system or region absolutely had no effect in adjacent regions or systems.

Balance of trade is commonly calculated by only considering goods [1]. America’s trade deficit is a deficit in the trade of goods; we usually have a services trade surplus [2].

When this administration has messaged [3] and made trade policy [4], it has used that goods-only view of trade, i.e. it ignores services.

Microsoft exporting Azure as a service has zero impact on how many goods America buys or sells. (If anything, it might increase the goods deficit if the servers Azure runs on, or the buildings its staff occupy, use any foreign components.) So by this administration’s accounting, the EU reducing its purchases of Azure is great if they e.g. buy two more Hershey’s bars. That’s economically nonsense, and that is the problem.

[And thank you! :)]

Yeah I’m from MN so my perspective is skewed too.

6 of the 64 schools with Div I NCAA hockey teams are located in my state, and 5 of them are small state or private schools. Massachusetts has 10, New York has 11, Michigan has 7.

Over half of the Div I hockey teams are in the four states mentioned above.

I dunno, often people say libraries are over used, at least in the JavaScript world.

My celery/RabbitMQ-based web crawler failed because of the Cloudflare CAPTCHAs, I figured it was best to empty out the queue and archive it. I asked copilot what to do and it told me to use a CLI program. “Does that come with RabbitMQ?” “No, you download it from GitHub”. It offered to write me a Python script but the CLI program did exactly what I needed. It got an option wrong but I’d expect the same if I asked a friend for help.

I'll probably get flamed to death for saying this, but I like Jürgen. I mean, I don't know him in person (never met him) but I've seen a lot of his written work and interviews and what-not and he seems like an alright guy to me. Yes, I get it... there's that whole "ooooh, Jürgen is always trying to claim credit for everything" thing and all. But really, to me, it doesn't exactly come off that way. Note that he's often pointing out the lack of credit assigned even to people who lived and died centuries before him.

His "shtick" to me isn't just about him saying "people didn't give me credit" but it seems more "AI people in general haven't credited the history of the field properly." And in many cases he seems to have a point.

The stock purchase plans at the two non-FAANG companies I worked for that offered them were amazing.

One of them took money out of each paycheck for a quarter and then gave you the better of the price of the stock at the start or end of the quarter. So you got a chance at risk free profits if the stock jumped. I was told that some people put their entire paychecks into it until they put a limit on the percentage of the paycheck you could put in.

The other one was a 15% discount off the stock price, again, done quarterly. Which doesn't sound huge until you calculate the annualized return. The annualized return on the first paycheck of the quarter was around 80%, the annualized return on the last paycheck of the quarter was around 3,000%. No lock up period and the smart thing to do would be to sell immediately and pay the short term capital gains tax.

I'm not smart, I still have the stock from that one. It keeps going up but it could also go to zero at any time. I don't want to pay the capital gains tax though. I should probably look at put options. First world problems.

I'm thinking about it.

Is it road-accessible? What kinds of vehicles can get there?

The cars in the article have twice as much range as a gas car or more, even in the cold. And it's easier to charge them at remote locations than to get fuel deliveries to those same remote locations.

I'm sure a scenario could be contrived where any type of car wins, but on average I expect a long range battery car to do quite well.

You apparently didn't try walking around. Give it a shot - you'll find that the matter you are made of isn't pinned to the space it's in.

Gravity ensures that structures at the cluster level and below don't expand as the space they're in expands. The space they're in is expanding just like it is everywhere (assuming a cosmological constant) - gravity just holds them together. Which is what I mean when I say matter isn't pinned to space - it just slides through it.

Gravity is too weak to affect distant objects, so we see the effects of the universe's expansion when we look at them.

I recall a C64 game(or Amiga, but I'm fairly sure C64) where you settled the solar system. The Moon, Mars, Venus, Titan, etc.

You even had to genetically engineer your colonists, so they could withstand the environments. Fun game, but I can't find it via Google.

If anyone knows this game, please share. I'd love to play it again.
Show HN: I built a mobile site for sharing Costco .97 clearance deals
by coolwulf | 2025-06-20 21:55:29+00:00
Hey Costco lovers!

If you’re like me, you’ve probably noticed those legendary clearance deals at Costco ending in .97 — the ones that fly off the shelves and disappear before you know it.

So I built a mobile-first website: https://97deal.shop

It’s a simple community-powered app where people can:

Snap & upload .97 price tags they find in-store (Use AI to auto generate the item number, title and price)

Tag the location (Costco warehouse)

Search and browse recent deals near you

The goal is to make it easy for all of us to share these hidden gems before they’re gone

Still early days and open to feedback. Would love your thoughts or ideas!

> If china wants to continue subsidizing their industry below costs of manufacture I see no reason why we shouldn't exploit their generosity

Because the unfair advantage distorts the market leading to a potentially otherwise noncompetitive product destroying the competition at which point they can (and will) jack up prices, so not only do you get more expensive vehicles, but you've also destroyed an entire industry and several adjacent industries at the same time.

It's not like you can't just snap your fingers and re-establish a vehicle manufacturing supply chain once it disappears.

I get people just want cheap vehicles, but the short-term benefit simply isn't worth it.
by bas_sen | 2025-06-20 21:57:01+00:00
Totally fair and not rude at all. I appreciate the honest feedback.

Right now, I'm still tuning the backend and experimenting with different types of videos. I definitely want to strike a better balance between fun/short-form content and deeper, high-quality creators like Scott Manley.

Would love to know what you look for in a great rabbit hole — I'm collecting that feedback to improve the next batch.

I mean, sure, why not, and I'm not opposed to using array languages as a fun hobby (which seems to be the spirit of this). I just noticed that the selling points in the introduction to the manual were not very compelling to me as a Matlab/Numpy user, and since sometimes people bemoan that array languages aren't more widely used, I just wanted to say, hey we do have powerful "array languages" that imo are strictly better on things that matter for most real work, so it's not surprising.

I totally get where you’re coming from but for me it’s the predictability that’s key. Hamburger menus are familiar but they’re also not always there. On a traditional native UI you’d always have a menu bar, you’d always have a File and Edit menu. These days you may have a hamburger menu but it also may just be a wrapper for a menu bar. It’s just all a bit……vague I suppose.

Tbh it doesn’t matter really. As I implied in the previous comment, I can’t imagine many people bemoan the fact they can’t press Alt-f to get an illustrative menu drop-down, even if I do.

Many of them. While historically the life of the peasantry (and pastoralists and hunter-gatherers) was stereotypically 'nasty, brutish, and short,' war activities were often carefully circumscribed and oriented around set piece battles. The disregard for such conventions was part of why figures like Attila the Hun, Genghis Khan, and Tamuslane were so reviled.

The anthropology of war is a lot more complicated than most people appreciate, because much of our mental imagery on historical warfare comes from movies and other fictional narratives. John Keegan's War in Human History is an accessible starter book on the topic.

I fear it often cuts a different way. Everyone wants it so that they can have the benefits of the car, along with the benefits of nobody using a car. A friend I was talking with called it the "main character syndome."

It is a lot like people wanting city life to look a lot like college life. Without wanting to live in dormitories where people are also raising kids.

It's actually more than just labels, it's sales requirements (can't sell in the EU otherwise):

> Durability: Devices should be resistant to accidental drops and protected against dust and water.

> Battery longevity: Batteries must endure at least 800 full charge and discharge cycles while retaining at least 80% of their original capacity.

> Repairability: Manufacturers must make critical spare parts available within 5 to 10 working days, and continue offering them for 7 years after the product is no longer sold in the EU.

> Software support: Devices must receive operating system upgrades for at least 5 years from the end-of-sale date.

> Repair access: Professional repairers must have non-discriminatory access to any required software or firmware.

And if you're wondering, some of the stuff you've heard recently even from places like Apple is them preparing for this legislation to go into effect, just spun as "corporate goodwill".

I don't think it's quite this reductive. Turnout in 2020 is estimated at 65%, which is not quite two-thirds of the population. 2024 was slightly lower at 63%.

That's still missing a significant fraction of the population. Sure, you could make the argument that 2/3s is probably pretty representative, but I'm not sure I'd agree. I think there's good reason to believe that a voter who shows up is inherently not representative of a voter who does not. When elections are decided by such small margins in many places, that unrepresented third can easily change the outcome.

Maybe they truly don't care, and perhaps they should be given the option to vote as such, if they're required to vote.

I also don't think presidential elections are actually very meaningful when it comes to national politics (or politics in general!), but I feel like my opinion on that is changing given the current administration's efforts to maximize presidential power and their success in doing so.

Hey everyone! I've been working on this project for a while and finally got it to a point where I'm comfortable sharing it with the community. Eion is a shared memory storage system that provides unified knowledge graph capabilities for AI agent systems. Think of it as the "Google Docs of AI Agents" that connects multiple AI agents together, allowing them to share context, memory, and knowledge in real-time. When building multi-agent systems, I kept running into the same issues: limited memory space, context drifting, and knowledge quality dilution. Eion tackles these issues by: • Unifying API that works for single LLM apps, AI agents, and complex multi-agent systems

• No external cost via in-house knowledge extraction + all-MiniLM-L6-v2 embedding

• PostgreSQL + pgvector for conversation history and semantic search

• Neo4j integration for temporal knowledge graphs

I'm curious what the HN community thinks about this approach. Are there specific use cases you'd find valuable? Any architectural concerns or missing features?

I don't think a titanium coating over something else is going to deliver that.

I think the reason titanium glasses feel nice is primarily because they have minimal contact with your skin and very low mass.

My frames weigh 6 grams, with lenses they're 14 grams. The Meta Ray Bans are 50 grams. If you could make the frames from pure helium they still wouldn't feel close.

> For beginners, Fedora is the perfect choice.

Last time I tried another round of "let's install the most recent versions of popular distros on random laptops I have", Fedora was the most finicky about hardware. As in literally wouldn't even boot into live CD on one of said laptops, and had troubles with graphics on others.

The thing that worked every time? For the past decade or so, it had consistently been Linux Mint for me.

On the one hand: an agentic browser sounds like a cool idea. Being able to automate things with an agent on the client side is crazy powerful.

On the other hand: this has the potential to be an absolute security Chernobyl. A browser is likely to be logged into all your sensitive accounts. An agent in your browser is probably going to be exposed to untrusted inputs from the internet by its very nature.

You have the potential for prompt injection to turn your life upside down in a matter of seconds. I like the concept but I wouldn't touch this thing with a ten foot pole unless everyone in the supply chain was PCI/SOC2/ISO 27001 certified, the whole supply chain has been vetted, and I have blood oaths about its security from third party analysts.

Okay, a heated debate in my slack group is now going. We need more deets:

* When you say that you don't hand-wash, can you clarify? Does that mean you just take the dish and put it directly into the dishwasher after throwing any large chunks of food away? Or do you rinse it or even soap it, you just don't scrub it thoroughly?

* You mention washing the dishes multiple times per day. Does any food actually dry on your plates before the dishwasher gets run?

* You don't have a problem with fingerprints or lipprints on glassware?

* Do you feel like the salt tank has benefits beyond hard water mitigation?

I learned to consider that if one brings up Dunning-Kruger...projection/irony may be at play.

Anyways...I've had a few reoccurring issues with libraries. Note that the language is framed on a case by case basis...not general rules.

1. The essential implementation is a small amount of code...wrapped in structures just for packaging essential code. The wrapping code can be larger & more complex than the essential code.

2. There's small differences between what's needed & what's provided. Which requires workarounds for the desired outcome. These workarounds muddy the logic & can be pervasive at scale.

3. There can be dissonance between the app architecture & the library api.

4. Popular libraries in particular...create a culture of thinking in terms of the library/framework. Leading to resource inefficiencies...And outright dismissing solutions that are a better match for the domain. In short, the library/framework api frames the problem & solution...Which may not match the actual problem & optimal solution.

5. The library/framework authors are concerned about promoting the library/framework. Not solving the actual problem. Many problems need to be solved. The library/framework just be the "Golden Hammer" to pound in your screw.

With all that being said...there are many useful libraries that define & solve problems in their particular domain. Particularly with common, well defined, appropriately scoped requirements.

I don't know if this is true. An LLM just today recommended a library I had never heard of, and after doing some due diligence, it looks solid.

This is analogous to folks who claim nobody is going to be able to learn software engineering any more. I think it is just the opposite. LLMs can be an awesome tool for learning.

Google Analytics is a tool that websites use to track users, similar to how a store might use a pen & paper to keep track of phone numbers or names. The store made the decision to buy the pen to track users. Why are you angry with the pen company?

Google Analytics is not going around tracking users. They provide a service that the website you decided to go to (cnn.com, bbc.com) is using. If you have to be angry, be angry with cnn or bbc.

> And honestly, we feel like we're constantly fighting the browser we use every day. It's not one big thing, but a series of small, constant frustrations. I'll have 70+ tabs open from three different projects and completely lose my train of thought. And simple stuff like reordering tide pods from amazon or filling out forms shouldn't need our full attention anymore. AI can handle all of this, and that's exactly what we're building.

So your thesis is that an AI agent should decide what I pay attention to, rather than me?

What could possibly go wrong?
