matsemann··on Coding expertise is going to collapse from AI reliance
Not everything is encoded in code, though.
matsemann··on Coding expertise is going to collapse from AI reliance
Sure, but I'm only able to do that because I'm intimately aware of everything in the code base. The more I do this where the LLM ends up writing the code (even based on my decisions), the less good critique I'll be able to give in the future.
matsemann··on Coding expertise is going to collapse from AI reliance
Works for a demo, but quickly stagnates. Future models may of course push the limits further, but right now it quickly goes sideways without someone knowledgeable at the helm.

Before, if I would start working / thinking on a problem and discover it was harder than anticipated, that often was a signal that the feature may not be worth it. Because implementing it doesn't fit the current model of how things work or similar. Then it was back to the drawing table and find a better way of solving the underlying issue.

But an LLM just happily chugs along and does it, no one feels the friction, which means you never stop up to think if you're solving the right problem, or in the right way. I'm already seeing this bite us in the ass, as you get hacks upon hacks.

Yet, here you are, commenting :)
matsemann··on Tragically, as many as 9625 out of every 10k individuals may be neurotypical
> people constantly self-diagnosing

Is this actually happening widely, or just in some spaces and it blows it out of proportions?

> constantly seeking to remind both yourself and society of your neurodivergency and any shortcomings you have with that seems almost like a crab bucket mentality

Is this what's happening or what you believe is happening? To me, it however looks like much more people are getting the help and support they need for this, compared to when I was a teenager. To me it's not learned helplessness or what it is you're trying to describe, but learning how to navigate society, and society being more aware of other's struggles. In the same vein that learning about structural racism isn't about disparaging people, but lifting everyone.

"Shortcomings" may even be the wrong word, as for many it's just different, not worse or better. Hence educating people like you is good.

Or your behavior is different on a cloudy day? More covered in clothes, not sitting still in the sun at the beach all day etc.
matsemann··on How does IKEA come up with names for its products?
means "to step" or "step on" in Swedish, at least.
matsemann··on Scientists stunned by children's lung recovery in ultra low emission zone
I grew up in a small town in the mountains in Norway. There is a children's "hospital" there (Geilomo Barnesykehus), where kids come to live because they can't live in the cities. Kids with severe asthma, eczema and some other conditions. It started as far back as the 1930s, still unfortunately a problem so kids have to come live there away from their families.

matsemann··on Does anyone run Postgres without PgBouncer?
Python: absolutely necessary due to the amount of processes and various deployments to run an application once it grows.

Java: never felt the need even on quite big apps. As it's much easier to share a connection pool locally, it's not as many single connections across the whole app.

matsemann··on Ask HN: How do you keep up with HN these days?
I mainly press "past" in the top menu and skim the top posts of the previous days. It doesn't surface every interesting post/discussion, but most of it.

There's also the "hidden" https://news.ycombinator.com/best which is a bit the same, but not per day

matsemann··on "That's not SOC 2 compliant"
Yeah, saying it's verified with tests is kinda moot when the code change can just modify the same tests or verifications that will be run on it.
matsemann··on "That's not SoC 2 compliant"
They (companyin the article) don't, though, hence the question. Is there even one set of eyes on this code, given the amount of agents they use?

matsemann··on Bike Bureau: Report Bike Lane Obstructions
> And you can no longer separate bicyclists from the motorized regulation-circumventing bikes and scooters

Why not? Why should how someone else acts impact what you think of me? I see this all the time in these discussions. Cyclists are responsible for what any cyclist ever has done. When drivers break the law (which statistics say they do to a greater degree), it's however those individuals that are to blame.

matsemann··on Bike Bureau: Report Bike Lane Obstructions
Where can the data be found?

Would be nice if the map supported date filtering to see trends, but also to avoid lots of (in the future) old data. Like easily select only a specific year, last week etc.

matsemann··on Bike Bureau: Report Bike Lane Obstructions
I saw someone bike with their kids to school in a protected (raised) cycle lane. A narcissistic driver came and drove over the curb and parked in it. No easy way to to the sidewalk due to a fence and plants. The kids therefore had to go around the car by biking to down the curb and into the lane with cars and then lift their bikes up again.

Do you think having 6 year olds biking in the middle of traffic is acceptable, just to placate drivers? And it's 100 meters and then it's a new car. And another one. All the time.

matsemann··on Bike Bureau: Report Bike Lane Obstructions
The reason some pedestrians feel cyclists pose a bigger threat than drivers, is mostly due to car centric infrastructure. Cars get all the room, and cyclists&pedestrians get clumped together. Of course you see little conflicts with cars when you're physically separated from them.

Additionally it's a form of servility and motonormativity. Most people accept that they themselves have to obey cars, so no jaywalking or other behavior, most people go out of their way to avoid conflicts with cars (due to the risk), which again makes the drivers seem less of a threat. But only because you yourself have removed yourself from the situation.

In total, the numbers don't support the impression. Literally no one dies from being hit by cyclists. Vs thousands upon thousands die from being hit by vehicles each year.

matsemann··on Bike Bureau: Report Bike Lane Obstructions
I've previously asked my municipality for numbers on how many tickets they give for cars illegally parked in cycle lanes. It was something like ~6 a day in total. Between over a hundred city officers out and about to ticket stuff. Which is weird, because just on my bike commute home I see more cars in cycle lanes like that. There are multiple social media accounts dedicated to photograph cars in their local cycle lane. It's epidemic, and no one cares to fix it. And this is in a bike friendly city (Oslo).

Nice page showing where it will be, with times and visualizations for any point/city.

matsemann··on WorldClaw Agentic 3D open-world generation at scale
There are millions of games. When choosing which one to play, you've normally chosen one that looks polished over one that does not, because of what it signals. Now that signal is gone, can't easily discern what's a sloppy crappy game vs one that's actually fun to play.
matsemann··on France to ban unsolicited telemarketing calls
Norway has the same law. I get no spam calls like this from Norway.

What I do get is spam calls from abroad. Often with a spoofed Norwegian number. Why can't operators block this? I know call centers and various things need to "spoof" a number they own, and when I myself call from abroad my Norwegian number will come from outside Norway.

But why can't they attest the numbers somehow? Owner of +47 XXXXXXX is currently not abroad. So why allow someone from the other side of the world to call me pretending to come from that number? Why does the Norwegian operators allow that?

matsemann··on The original URL for this prediction will no longer be available in 11 years (2011)
At a certain bet size it would almost be self-fulfilling, heh, as one side would be very incentivized to keep at least that url working (buying the domain + hosting it if the page were to die)
matsemann··on Timeline of the OpenAI accidental attack against Hugging Face
Simon's really doesn't bring anything useful to the table.

One question I'm stuck with after reading is why. Why did the agents do these things? I get them being adamant on getting internet, but why did they continue? Why hack HuggingFace?

matsemann··on A year of fighting scrapers on my 1.5 million-page website
That's an incredibly dishonest characterization of what I wrote. Please re-read the guidelines of the site, they say exactly not to do that.

> saying that you should be entitled to behave as you please because you are a paying customer

No, I'm saying my usage of the site was exactly as if I used my browser agent instead of the llm agent. It visited the category for the product I was interested it, then it visited the pages for the various items to read their specs. Exactly what I would do in my browser as well. In the end I bought one of the products. Point is that I used the site as desired. No extra calls / mass scraping, no stealing of content without them getting anything in return, no breaking of rules.

matsemann··on A year of fighting scrapers on my 1.5 million-page website
No, the first case I used their website in a way that gave them a sale, which is why they have it. Why is it a straw man case when it's reality? Don't argue in bad faith, please. Express your reasoning, like I did, don't just dismiss me because you disagree..
matsemann··on Managing AI Coding Costs at Scale
My experience is that your description works for a certain time, since you're knowledgeable of the codebase and can guide it. But after too many iterations with not hand-holding the llm, it quickly gets unwieldy.
matsemann··on A year of fighting scrapers on my 1.5 million-page website
I use this. Buy a domain, set up a cloud flare pages that builds an Astro page on git push, served statically for free.
matsemann··on A year of fighting scrapers on my 1.5 million-page website
I don't disagree, but there is a sliding scale here.

For instance, I wanted to buy a piece of equipment the other day from a local company for a specific usecase. I wanted to find a specific price/weight/specs ratio, and asked an llm to loop through the 20 or so items, fetch their page and calculate and present some values for each. This then led to me going and buying the one I found. So the llm was mainly just an extension of me clicking into every page and making a spreadsheet myself.

However, if it were to continuously poll, or just scrape or something with no intention of buying, I would be no better than a bot.
