this reminds me when early on in Github Copilot journey when people were asking "what if it accidentally reproduces GPL code and I get sued" and Microsoft said they'll cover the legal costs for anyone using Github Copilot.

The big players (Google, Microsoft, Meta, Nvidia) don't want ai startups failing. In fact they are terrified of that. Can you imagine the market shock if windsurf just went under in 1 year. How fearful all investors would be? How the whole market is gonna react? We are told that AI is basically a money printer. If you release a product for $20/month and a couple of months later other companies (with much better margins by definition) release competitor for $250 then $300 then $400 something is clearly not adding up even among the higher numbers.

In some neighborhoods, the equipment wasn't able to support 56kbps so 33.6 was the best available. That's how my parent's house was. Too far away to get DSL. Lines were too noisy for 56.6. My parents tried HughesNet at one point, but it was shite. Starlink would have been a good option, but they eventually strung fiber to the area before Starlink was still an idea on paper.
I built an app that uses math to find the sweet spot for restaurant meetups
by mayukh180505 | 2025-08-09 05:36:31+00:00
I recently built an iOS app called Settld: Group Restaurant Finder that helps friends decide where to meet by finding restaurants that are roughly equally far from everyone’s location, and displaying information about them.

We’ve all been in chaotic group chats where no one can agree on where to eat — this app cuts through that by calculating a “sweet spot” for the group. For 2 people, it’s the midpoint. For 3 people, it’s the circumcenter. For 4–6 people, it uses a minimum enclosing circle approach (Welzl’s algorithm) to minimize the maximum distance anyone has to travel.

It then shows the top 15 nearby options so there’s no more “where do we meet?” chaos — or $50 dinners after a gruelling 2-hour trip just because no one planned.

I’d love to get your thoughts on the concept: https://settld.space/

Tbh, all these sound like obvious noob mistakes. If I'd be trying to fake coming from NY then of course I don't use my russian-language browser or run Javascript code in a non-sandboxed environment that leaks where I am. The login and auto-complete channels don't really work either because all those things use HTTPS/SSL/TLS/... nowadays and you are rarely the endpoint. If you are and they still do this then again, they don't really know what they are doing.

It doesn't need a highly skilled+funded state actor to avoid those mistakes.

It’s not so much that you’ve made any mistakes or omissions as much as all of these things do different, similar things, but don’t do the exact same thing.

For example, an array and a tuple are both aggregate types, but arrays store multiple value of a single type, and tuples store multiple values of the same type.

Some of these do boil down to “named or anonymous” but that’s also two different things.

There's a difference between acceptable standards for a truly professional product that you'd have to certify and hobbyist stuff.

Beyond short circuit/overcurrent, overtemp, over voltage, under voltage protections, what else would be necessary to ensure safe usage of the cells from an electrical perspective? Ie. What additional protections would a batter management circuit need to be safe in normal circumstances?

The context after application of the algorithm is just text, something like 256k input tokens, each token representing a group of roughly 2-5 characters, encoded into 18-20 bits.

The active context during inference, inside the GPUs, explodes each token into a 12288 dimensions vector, so 4 orders of magnitude more VRAM, and is combined with the model weights, Gbytes in size, across multiple parallel attention heads. The final result are just more textual tokens, which you can easily ferry around main system RAM and send to the remote user.

We don't know what deal they made with the VCs, but they could have multiple liquidation preference agreements.

> A liquidation preference multiple (e.g., 1x, 2x) determines how much investors receive before any distribution to common shareholders. A 2x preference means investors are entitled to twice their initial investment amount before others receive payouts.

>EV used cars are basically dead batteries

True, a local club has an Electric 1913 Detroit that ran for 78 years on the same set of Edison cells. These cells were replaced due to leakage rather than capacity loss by the club re-builders a few decades back. Think about the total distance traveled compared to a modern EV. YMMV was never so true.

The battery is the car for most EV, and given most manufacturers adversarial relationship with external repair shops it is effectively e-waste in 8 to 14 years. =3

> EV used cars are basically dead batteries.

A quick googling shows some sources claiming EVs are in general designed with a planned service life or around 10 years.

That's basically the same planned service life for ICE cars, which some sources claim it tends to be 12 years or 200k miles.

One source suggests battery capacity in EVs drop less than 2% per year on average.

These numbers seem to contradict you, but you show your data so that we can look into it.

In LA "alone"? The city of Los Angeles has a population of 3.8 million people and in 2025 a budget of about $14 billion. That would be something like 0.01% of LA's budget.

https://cao.lacity.gov/budget25-26/Budget_Summary/2025-26Bud...

That's like saying "At Google alone they spent X dollars" as if it was indicative of companies in general.

To be fair if you mean Kenneth Hahn, and are referring to when he was LA County Chair in 1978, obviously that would be a much larger sum relatively. But it's the largest city in CA now and it was then too.

The loss of pay phones is a really good example of saving pennies and losing essential service as a result of technological progress. When companies started taking them down, local governments should've stepped in to take over or help form a non-profit to maintain these services. There's a number of times where I've been out and about and my phone either can't get service or just inconveniently died on me, and having easy access to a pay phone helps prevent one from being totally stranded. And strangers, rightfully so, are reluctant to share their phone.

Some years ago I was flying home, and it turned out someone had called in a bomb threat. So, naturally, they had ramped up the security scan to the max, causing a massive queue.

The landside area was packed to the brim with travelers waiting in line, mixed with the people on their way to check-in pushing their trollies loaded with suitcases.

I've never been so scared, waiting in line for security, as I imagined how easily anyone could pack 6-7 huge suitcases filled with explosives onto a trolley in the parking lot right outside, move into the packed crowd without suspicion and set it off.

No need to get on a plane.

>I kinda feel like this is a self-placating statement that is not going to stay true for that long. We are so early in the process of developing AI good enough to do any of these things. Yes, right now you need senior level design skills and programming knowledge, but that doesn't mean that will stay true.

So you really think that in a few years some guy with no coding experience will ask the AI "Make me a GTA 6 clone that happens in Europe" and the AI will make actually make it, the code will just work and the performance will be excellent ?

The LLMs can't do that, they are attracted to solutions they seen in their training, this means sometimes they over complicate things, they do not see clever solutions, or apply theory and sometimes they are just stupid and hallucinate variable names and functions , like say 50% of the time it would use speed and 50% of the time it would use velocity and hte code will fail because undefined stuff.

I am not afraid of LLMs taking my job, I am afraid of bullshit marketing that convinces the CEO/management that if they buy me Claude then I must work 10x faster.

> Accenture

Most companies work with these IT sweatshops (Accenture, Cognizant, Wipro, Tata...) only once, before learning why others try to avoid them. And people who spend a very long time at these companies are at a disadvantage, unless they are looking for work at another one of these sweatshops.

And of course, the role "manager" is synonymous with paper pushing. Expensive paper pushing.

OP exaggerates the difficulty. You can trivially parallel the vast majority of lithium batteries so long as their voltage is reasonably close (I personally wouldn't fuss much over a 100mv difference, or even more in most cases, unless it's a massive battery or a power cell capable of delivering and accepting very high currents - charging most cells will often involve raising the voltage 200-300mv during the constant current phase, so you can safely parallel with a difference like that)

You can match up pretty different batteries in parallel as well. One will take more load etc, but this is not usually a problem. It's not ideal, but I think people often exaggerate the dangers.

Series is much more problematic, since most balancing circuits have very limited capacity to balance mismatched batteries.

My timing belt (chain), clutch, and gearbox last 130k+ miles. Thats the life of some EV batteries. Coilpacks cost $100. You are not wrong, but I have not had any major repair on any of my cars under 50k miles. Maintenance does exist but it doesn’t wildly drive up the cost per mile

There is also suspension, a/c, wipers, and interior electronics.

The difference between ice and EV stops after the drivetrain and most ice drivetrains are rather reliable these days. My 10 year old ice sedan costs about 0.18/mi. I would be interested to know what a comparable EV would cost, considering half of my cost is basically gasoline

Update: it seems EVs cost under 0.10/mi with figures coming in between 0.03 and 0.08. This doesn’t explain if this is all costs (including things like washer fluid, regular maintenance etc) or estimated costs+charging. My costs were tracked over a 6 year span

If you were trusting photos to be pictures of the real world before AI then you should never have had that trust in the first place. You should thank AI companies for opening your eyes to what was already fooling you.

Even if they are real, does it really matter when the camera is doing superhuman work with things like a 27 km zoomed in picture of a building or composite of 300 separate exposures. If you get to combine exposures, why not just expose a moon separately from a building and combine them in the computer?

I get similar accuracy to claude code using claude desktop app with a file+bash mcp (different tools same performance).

My guess for why GPT5 scores more on benchmarks is that they evaluate on well defined tasks with all instructions given at the start.

Real life is multi turn. Multiple set of prompts to adhere to. This is where Claude is likely better.

> EV used cars are basically dead batteries.

What piddling nonsense.

Plenty of outrage in replies. Here's a recent article with some specific figures: After more than 250,000 miles, Ford Mustang Mach-E still has 92% battery life. https://electrek.co/2025/07/22/after-250000-miles-this-ford-...

Batteries are rarely dead, they just loose capacity. (And quite slowly at that!!) Resale goes down if you decide there's not enough capacity left and want to sell, but the car is still fine. Eventually, yes, someone might opt to battery swap: for a Tesla that's currently ~$10-20k depending. But in another 10 years? It's quite likely battery prices will have continued to decline, & costs will be less.

Flipping the bozo bit on this guy.

I don't think you're making it up, but without a lot more details I can't be convinced that your methodology was robust enough to prove what you say it shows.

There IS evidence that would satisfy me, but I'd need to see it.

I will have a high bar for that though. A Reddit thread of screenshots from nine months ago doesn't do the trick for me.

(Having looked at that thread it doesn't look like a change in model weights to me, it looks more like a temporary capacity glitch in serving them.)

The default outputs are considerably shorter even in thinking mode. Something that helped me get the thinking mode back to an acceptable state was to switch to the Nerd personality and in the traits customization setting tell it to be complete and add extra relevant details. With those additions it compares favorably to o3 on my recent chat history and even improved some cases. I prefer to scan a longer output than have the LLM guess what to omit. But I know many people have complained about verbosity so I can understand why they may have moved to less verbiage.

> It is just insane how much bad press Tesla gets compared to other car makers.

Most of the other car makers weren't promising FSD next year for decades, or have their CEO giving the Roman Salute at MAGA rallies, or regularly having ketamine-fueled affluenza breakdowns on Twitter. Also, their ticker is a truly bizarre memestock.

There's easy targets, and there's painting one on your own back.

> ICE used cars are often in relative good working condition.

Yes! ICE cars have 10,000 moving parts, and also chambers for burning stuff, lots of oil and residual burnt stuff. ICE cars work exactly like the human body, exercise helps live longer. EV cars have nearly no moving parts, they get obese and die sooner.

A good ICE vehicle without a CVT can last a long time.

Regenerative braking means people don't need brake maintenance as often, but also have to replace tires more frequently (especially lazy people that don't rotate the tires regularly.)

Personally, I wouldn't buy a North American ICE model from the past 17 years. Go to a site like Edmunds and sort by worst reviews first, and run if you see electrical or drivetrain complaints. You will have to go back decades to find a reasonable quality domestic ICE model. =3

> My timing belt (chain), clutch, and gearbox last 130k+ miles. Thats the life of some EV batteries.

If that's the life of your battery, you get it replaced under warranty. Since no supplier wants to have to replace the bulk of batteries under warranty that seems to just be false in Tesla's case at least.

Your cost per mile including gas really depends on where you live. Because gas prices vary wildly.

Most premium ice cars aren't cheap to maintain unless you're doing a lot yourself

Never owned a Tesla, but the amount of horror stories involved with Tesla, its often a hard battle to get warranty, especially around the battery when it involves a second hand vehicle. Even first owner vehicles are often a mixed experience.

I assumed you never opened the link you point to, as its literally in the first line very clearly "Your new Tesla" (as in, not a second hand vehicle). Ooooo, fun, look a bit lower in the actual model info. Your vehicle need to return to the first registered area to gain warranty for a resell. Here in Europe we see often cars being sold that come from Spain or other area's, in Germany. By that contract condition, it need to go back to Spain for a battery fix. lol

Tesla Vehicle warranty is at discretion of Tesla bla bla ... Battery max 8 years, or 240.000km, ... Lots of other exceptions to that warranty.

And if you can apply the warranty, your also not getting a new battery, but a refurb based upon the whole description.

Fyi: Lithium batteries drop in capacity faster and faster when they go past the 80% mark. But legally, Tesla can shove anything in there. A 100% battery, a 80% battery, ... you get the point.

With a ICE engine, even on rental cars, you tend to get the same millage out of them, as a new one. Most issues are often more on the clutch or turbo, both relative cheap repairs compared to a battery pack.

People have been warned years ago, that second hand market for EV cars is going to be a issue because of the battery. Now we are seeing the effect on the pricing.

It’s almost as if there’s things that tip the bias against Tesla!

I for one can’t think of A SINGLE reason why anyone or any news outlet could criticize a nicer, more normal, grounded, unproblematic, controversial, or completely good and undeserving company than Tesla. /s There’s so much to like about EVs, and there’s no denying Tesla’s outsized role in bringing practical EVs to market, and kickstarting competition, which is mostly good, despite the tactics and controversy.

Trying to leave politics out of it, it’s also undeniable that Elon, in and out of his CEO role at Tesla, has done some really harmful, shitty, trust-destroying things. I think everyone can agree that reality cannot have possibly matched the hyperbole and marketing claims. The overpromising, and therefore untruths, good faith or no, alone are enough for me.

The dude’s fingerprints, and everything good and bad (mostly bad for some time now IMO) that come along with it, are all over Tesla.

There is a JS strings spec for wasm underway. https://github.com/WebAssembly/js-string-builtins

This feels so much like one of those cases where perfect is the enemy of the good. Node.js spent a decade being wrapped about the axle, convinced that cjs and esm could never work together. Ignoring that it worked great in standard-things/esm. But eventually Bun came around and that somehow made the case that all the hemming & hawing was nonsense all along, that doing nothing was worse than letting Fear Uncertainty and Doubt reign.

It just seems so unlikely that much of JS really matters for webidl. WebIDL specifies mostly structures and routes. It throws some exceptions but that doesn't seem particularly incompatible with wasm. WebIDL has promises, which is already pretty well solved by https://github.com/WebAssembly/js-string-builtins (which alas only Chrome seems to be moving on). GC is also in wasm now. I just don't get the defeatism. Fear Uncertainty and Doubt can be so seductive, anti-belief can be so fierce, and it sucks when things aren't perfect or when there's warts, but the paralysis here & anti-will seems so wildly disproportionately strong.

And if it’s the very first gen of the Leaf, then, as far as I know, they don’t have thermal management for the batteries. So it greatly stresses them both for discharge and charge and that manifests as reduced capacity.

Lithium cells are happy when they are around 20-25 degrees Celsius (about 75F?) but they don’t enjoy when it’s hot or cold. Likewise, they don’t enjoy full charges and discharges which I’d guess more probable in a smaller range car.

All in all, the first gen Leaf might not be a good benchmark for a more modern EV. Many things should be better now.

(This will not, as of now, make these models show up in the app. Maybe they will add support for this later.)

Doubly so when a $650 Epyc motherboard and a $650 Epyc CPU gets you 3x the threadipper's bandwidth and 1.5 the thread ripper pro's bandwidth.

This seems a bit complicated to me. They don't serve very many models. My assumption is they just dedicate GPUs to specific models, so the model is always in VRAM. No loading per request - it takes a while to load a model in anyway.

The limiting factor compared to local is dedicated VRAM - if you dedicate 80GB of VRAM locally 24 hours/day so response times are fast, you're wasting most of the time when you're not querying.

Modern batteries can last a long while though. If you take care of it and mostly keep it between 25-75% and don't supercharge it too often. There are Teslas with more than 300K miles on the original battery.

I have a model 3 with ~80K kilometers and the battery is as good as new. 2018 model. For someone that drives 10-15K km a year there's maybe 30 years more driving on this battery (400K km).

My previous ICE car had two head gasket replacements in the 10 years I owned it. I also had to replace the entire engine. Oil changes. Brake pads/discs, CV joints... So far the EV is way ahead and based on the current battery degradation should remain ahead.

Who provides a warranty over 130k miles on the battery! Cost per mile for gas was from $2.15 (yay covid) up to $4.21, average gas price paid over the life of the car is at $3.20. 98% of my fillups was 93 octane gas

My car is a premium (luxury) car
