Everything has false positives or negatives. 2 examples doesn't tell anything about how good or bad it is.
matsemann··on Understanding ChatGPT Work
It's kinda my point, though, that it's busy "manager" work if it really can be answered by an LLM. So yeah, getting answer from someone like Elon is exactly as useful as just asking the LLM myself.
matsemann··on Understanding ChatGPT Work
Honest question: why would I ever visit that site? It's just an insane amount of text. Not written or curated by you. Any need for me for this data would be fulfilled by just asking the agent myself, and with pointed questions it could float better what I need than this vomit of data?
matsemann··on Understanding ChatGPT Work
Not to come across as dismissive of your job, but if a "day's worth of email" can be done in 20 minutes now, it to me mostly highlights that it was mostly busy-work with little value and could have had another process? Good that AI improved upon the old process, though.
matsemann··on Hacking IKEA Furniture
Eh, most IKEA desk hacks is to buy the wooden kitchen countertop, cut it to shape, and put it on some drawers. So you're not really describing anything different.
matsemann··on Please stop flooding our projects with AI slop to furnish your CV
I was thinking the same. The amount of effort people went through just for a t-shirt. Now you can try to boost your career, far more valuable, and even with less effort. Of course it will happen, unfortunately.
matsemann··on CDs vs. NIMBY
If anything, my experience is that NIMBY's also strongly oppose things that would reduce traffic, noise and pollution. Because a low traffic zone, reduced speed limits, or bicycle lanes, would infringe on their ability to drive their car everywhere without any disturbance.
matsemann··on Nitter project received cease and desist
In Norway most withdrew from X. Norwegian police made a webpage, an rss feed, some push system and an API. So others have made bots that repost on various social media, but the source is no longer in a walled garden.
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.
matsemann··on Coding expertise is going to collapse from AI reliance
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.

matsemann··on Moderna reports first positive Phase 3 for mRNA neoantigen therapy in melanoma
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.

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.
