I got hopelessly addicted to running in college, then got a knee cartilage injury and haven't consistently ran in 3 years. Absolutely soul-disfiguring for those who love to do long slow runs like yourself. Cool data and visualizations!

Unreal that you rolled your own svg's for this instead of using d3.js. That absolutely blows my mind, great work!

The Windsurf section is interesting

> This, in the long run, is very bad for startups. The incentives for founding a company do still remain. ... The people who are getting screwed, however, are the folks who were never necessarily going to get rich — that’s reserved for founders, and appropriately so — but who could justify rolling the dice on a positive outcome as long as they had downside protection in the form of guaranteed employment with a Big Tech company if things didn’t work out.

It's not clear what Matt means by "who could justify rolling the dice on a positive outcome no as long as they had downside protection in the form of guaranteed employment with a Big Tech company if things didn’t work out" since as a class employees of a startup don't get guaranteed employment at a Big Tech company when things go south.

But this is feeling like the startup equivalent of spaghettification when black holes of incredible monetary gravity open up. The only ones who matter are the heads and the VCs who have sponsored them. Practically, it's a new front in how the existing ecosystem is anti-competitive.

As a VC, maybe I should just treat a graduating class from a top-tier school like a kind of investment, fund their academic research projects like they were a startup, and by so increasing their value to a Google or Microsoft participate in their additional worth at hiring time.

> don't think we can judge the progressive wing from the antagonistic media coverage and bilateral party disdain of them

No, we can judge by the actions and results. Police reform in New York was a failure. Education priorities in San Francisco were a failure. The entire activist-interest group orientation is broken.

> proactive work for less policing is not some sort of lunacy

It’s not. But the people who attempted it were lunatics.

Defunding the police is dumb. Rebuilding police departments from the ground up is not. Unfortunately the latter requires being realistic about the occurrence of crime and criminals in a population. (They’re not all victims of circumstance. And they can’t all be community organised into a sculpting job or whatever.)

My understanding is there are two performance differences here, one is vulkan outperforming DirectX, and one is reduced overhead on linux vs windows.

The Vulkan difference can actually be achieved on windows as well, by using DXVK on windows.

The overhead difference is most seen on the lighter games, like Dead Cells and Hades. It's why we see such massive increases in battery life for those games.

1. Canadian elections outside of Alberta have a different dynamic because they are a three/four horse race - and in certain election cycles, they have a lot of strategic voting (this last one was a good example of it).

2. Canadian Liberals aren't US MAGA, when they win an election they don't spend six months in caucus to figure out how they can do their best to punish the provinces and people that didn't vote for them.

There's a lot of far-right propaganda in Alberta that implies #2 is happening, but it's not actually factual. Its oil & gas sector has reached record output under the Trudeau government, and Carney is not exactly looking to kill it, either.

Transfer payments are really the only legitimate grievance Alberta should have with the federal government. All of its other problems are either imagined, self-inflicted, are caused by other provinces, or are caused by the US.

It's funny to see ARC just being described as a "data broker," which strongly implies that it doesn't play a role in facilitating the actual underlying consumer activity.

ARC and IATA absolutely do play such a role, as the financial clearinghouses for ensuring that travel agents (online and offline) and airlines can pay each other, and as gatekeepers/certification bodies for agencies to ensure these financial systems aren't abused.

Now, they absolutely do sell access to data to third parties, governmental and nongovernmental. But the reason they have this data isn't because they buy it to resell it; they are fully part of the funds flow for the underlying transaction. Whether they should be allowed to sell or share non-anonymized data on passenger records and prices paid is a very good question, but at the very least this is about as first-party as data gets.

https://www.altexsoft.com/blog/airline-reporting-corporation... describes some of these flows. (Here be dragons.)

It is not useful because it ignores population.

One property a useful measure of something undesirable (like CO2 emissions) should have is that if you identify the country that is doing the worst by that measure, and they were to change so that their economy works like that of the second worst country and their people live a lifestyle nearly identical to the people of the second country, that should improve the thing being measured.

Total by country fails at that. If China were to change so that they are basically a clone of the US economy and lifestyle their emissions would go way up.

Conversely, if the US were to change to be a China clone that would result in a big decrease in total emissions.

> India on the other hand has barely scratched the surface, no company wants to migrate manufacturing there

I don't think that's true. India has a large domestic market, high tariffs, and relatively low labor costs. It makes a lot of sense for products for the domestic market to be manufactured (or at least assembled) inside the country, and you see many manufacturers doing that. Some of them have success in manufacturing and go on to build for the export market in India; many have less success and accept the tariffs.

Cars today are better than 50 years ago, but not much better than 15 years ago.

You must be young.

Cars used to last five years before falling apart. It helped drive the whole auto leasing industry, because nobody wanted something that turned into an old rust bucket in half a decade.

The reliable Japanese cars came in, and every marker suddenly started offering five, eight, and even ten year partial warranties.

Today, a ten-year-old car is very common. I kept mine until it was 12-years-old, and in that time it never had a breakdown. Just tires, oil changes, and many lightbulbs. My previous cars (Volkswagen, Isuzu, Ford, Ford, Mercury) had long been scrapped by then.

> "Defund the police" was never actually tried

Isn’t this a No True Scotsmen problem?

Police budges were trimmed. Police forces were cut. Police remit, in the form of decriminalisation, was reduced. No jurisdiction abolished law enforcement (though San Francisco de facto got close). But I’d say those count as defunding the police to an extent.

Even then, we got disaster. Shockingly quickly. Shockingly powerfully. There is no threshold theory that suggests you get magical results cutting the police force by 30% instead of 3%; it’s thus reasonable to extrapolate and assume you get more of the bad.

Depends on what you're doing, right?

Let's take video streaming. I have a pretty compressed version of Arrival that's at 2GB and is a 4k movie ~2hrs long (the original file was ~2x the size). To stream that we need to do 2000Mb / (3600s * 2) = 277.8Mb/s. This also doesn't account for any buffering. This is one of my smaller 4k videos and more typical is going to be 3Gb-5Gb (e.g. Oppenheimer vs Children of Men). Arrival is pretty dark and a slow movie so great for compression.

Now, there's probably some trickery going on that can get better savings and you'll see used with things like degrading the quality. You could probably drop this down to 1.5Gb and have no major visual hits or you can do a variable streaming and drop this even more. On many screens you might not notice a huge difference between 1440 and 4k, and depending on the video, maybe even 1080p and 4k[0].

For comparison, I loaded up a 4k YouTube video (which uses vp9 encoding) and monitored the bandwidth. It is very spiky, but frequently jumped between 150kbps and 200Mbps. You could probably do 2 people on this. I think it'd get bogged down with 4 people. And remember, this is all highly variable. Games, downloads, and many other things can greatly impact all this. It also highly depends on the stability of your network connection. You're paying for *UP TO* 300Mbps, not a fixed rate of 300Mbps. Most people want a bit of headroom.

[0] Any person will 100% be able to differentiate 1080p and 4k when head to head, but in the wild? We're just too used to spotty connections and variable resolutions. It also depends on the screen you're viewing from, most importantly the screen size (e.g. phone).

Meritocracy is simply a means of preventing elites from kicking the ladders down, nothing more, nothing less. Once the ladders are kicked down, which all elites will inevitablely try to do, society will start to stagnate, your country will start to fall behind the others, and your quality of life will start to rot.

The key here is that while meritocracy is championed as a means of finding the best, it in reality functions as a system to keep out the worst. You want harness the ambitions in people, even if not everyone's ambitions can actually be met, and you want to mitigate the harms of nepotism, even when eliminating it entirely is impossible.

So the difference between qualifications and merit evaluation are moot from my perspective, the question you need to ask is if whatever selection criteria you prefer is vulnerable to ladder kicking. If you preferred way is more vulnerable than the current system then you are putting the cart in front of the horse.

Also to make my position clear, I can't tell either way in regards to what you have suggested. As far as I was aware, we already select based on qualifications, so it's unclear to me what the exact change you are proposing is.

The entire plot of the movie is included. You could play through entire story, but in practice that would take a very long time, even with digressions -- and even then, it would be the story just through a specific character's perspective.

The idea was to make something that stood alongside the movie as a companion piece, an alternative way of experiencing it, rather than just a promotional thing. It's been fun seeing players playing for 4+ hours and barely getting through the first half, when the movie itself is 90 minutes and change.

I may try to post a Show HN later this week with more details, since the technical details are kind of fun. It's fully custom-coded and uses some LLMs under the hood (more as a 'game master' than in a creative capacity). I worked with the writer/director of the film to translate the script to a more interactive-friendly format, but he basically did the interactive adaptation himself.

I worked on the movie as a technical consultant and they credited me as 'unix wrangler' (I can check having an imdb page off my bucket list I guess)...

Easter eggs if anyone finds this and reads this far: try typing 'chloe' or 'camus' in the character selection screen.

The point with the firecracker/bomb is this: Not just because it's the same type of tool means that it has the same cost/benefit analysis. The dangers of, say, firecrackers in the had of the general public, scale dramatically faster than the benefit, going from kid-safe firework to bunker busters. The same goes for "a cop with a camera" to "tag readers at every corner".

I think with encryption, the underestimate is on the other side. Everyone understand that bad guys using encryption is bad. But people do not see the upsides of encryption for the good guys, pretty much for the same reason as they do not see the downsides of data collection: I have nothing to hide.

I think there is a big difference when one still ultimately requires a physical act in the end and one is all mental.

You can much more easily use the physicality of your surroundings to physically deny yourself the food than you can deny yourself anxious thoughts.

With eating there are 2 components to it, mental and physical, so you have more opportunities and more options and avenues to potentially control it.

The additional options to control it should IMO make it at least some amount easier to control in the end since some people may be able to take advantage of physical controls to limit themselves where that's not an option for anxiety.

FYI the source you posted never claimed that John Terry's insurance tried to deny the claim, only mentioning that "some" insurance companies warn of it. However even that claim is questionable, because it isn't even from an insurance company, it's from a content marketing piece by an insurance comparison website.

I do this a lot and absolutely think it might even improve it, and this is why I like the current crop of AIs that are more likely to be argumentative and not just capitulate.

I will ask the AI for an idea and then start blowing holes in its idea, or will ask it to do the same for my idea.

And I might end up not going with it’s idea regardless but it got me thinking about things I wouldn’t have thought about.

Effectively its like chatting to a coworker that has a reasonable idea about the domain and can bounce ideas around.

I have mostly worked in aerospace software, and find this rather horrifying. I suppose, if your tests are in fact good and comprehensive enough, there could be a logical argument for not needing to understand the code, but if we're talking people's safety in the hands of your software, I don't know if there is any number of tests I would accept in exchange for willingly giving up understanding of the code.

Have used Cursor and I know that there is quite a bit of value between the model and the chat input box and it will be similar to Claude Code or Codex, it's what makes this agentic, it's just accessed through a different interface. So from that perspective, Cursor makes sense for folks that are already in the VSCode environment.

"Around me I see practices like "gratitude", "meditation" and "breathing exercises" get bandied around like they're some new profound thing as if we hadn't known about for thousands of years that have appeared in various guises universally throughout different civilisations."

These have been VASTLY improved and optimized compared to their traditional counterparts. Evidence-based trials with brain scans, and other methods.

For example, achieving strong vagus nerve stimulation on demand to activate the parasympathetic nervous system could take years(or they might never get there) to learn for traditional Buddhist meditation practitioners, and nowadays we get there in a few sessions of EMDR therapy.

I think you didn't get to the part of how it would work in practice. It's not that the leader is selected randomly, it is that the people that select positions are randomly chosen. Also, your criticism only is valid if everyone through that being able to sell an idea is critical for the leader. The leader role is to manage the resources to accomplish the goal of the team, what the goal of the team is, is up to the team to decide.

From the Wikipedia § Criticisms page:

> In his 2019 book The Meritocracy Trap, Daniel Markovits poses that meritocracy is responsible for the exacerbation of social stratification, to the detriment of much of the general population. He introduces the idea of "snowball inequality", a perpetually widening gap between elite workers and members of the middle class. While the elite obtain exclusive positions thanks to their wealth of demonstrated merit, they occupy jobs and oust middle class workers from the core of economic events. The elites use their high earnings to secure the best education for their own children, so that they may enter the world of work with a competitive advantage over those who did not have the same opportunities. Thus, the cycle continues with each generation.

* https://en.wikipedia.org/wiki/Meritocracy#Books

> In his book The Tyranny of Merit: What's Become of the Common Good?, the American political philosopher Michael Sandel argues that the meritocratic ideal has become a moral and political problem for contemporary Western societies. He contends that the meritocratic belief that personal success is solely based on individual merit and effort has led to a neglection of the common good, the erosion of solidarity, and the rise of inequality. Sandel's criticism concerns the widespread notion that those who achieve success deserve it because of their intelligence, talent and effort. Instead, he argues that this belief is flawed since it ignores the role of luck and external circumstances, such as social and external factors, which are beyond an individual's control.[91]

Mid-engined is most useful as a transition step to a modern skateboard design EV. Gets the center of gravity low and closer to the actual center point of the car, which a skateboard design then improves.

Corvette can't admit to aspirations of a Pure EV this decade (thanks, politics), but in my opinion, that's the only way to absolve a lot of the GM executive sins on being wishy washy about EV futures.

Context Rot: How increasing input tokens impacts LLM performance
by kellyhongsn | 2025-07-14 19:25:15+00:00
I work on research at Chroma, and I just published our latest technical report on context rot.

TLDR: Model performance is non-uniform across context lengths, including state-of-the-art GPT-4.1, Claude 4, Gemini 2.5, and Qwen3 models.

This highlights the need for context engineering. Whether relevant information is present in a model’s context is not all that matters; what matters more is how that information is presented.

Here is the complete open-source codebase to replicate our results: https://github.com/chroma-core/context-rot
