invalidusernam3··on Ireland shuts last coal plant, becomes 15th coal-free country in Europe (2025)
How much impact does it realistically have on climate change? I would expect it to be relatively small compared to things like owning a car?

In a perfect world we would want to reduce emissions as much as possible in every facet of life, but in the real world I think we should pick battles that have the biggest impact.

invalidusernam3··on Living human brain cells play DOOM on a CL1 [video]
Why do you quote only the end, the full sentence is: We cannot discard, for example, than an ant has a greater qualia level than

They're saying that since we don't know how to "measure consciousness" we can't be certain that an ant doesn't have more "consciousness" than us. Obviously it seems very unlikely, but we can't be certain

invalidusernam3··on Half million 'Words with Spaces' missing from dictionaries
If the compound words all have single word entries in the dictionary that when combined mean the same thing what is the point?

Water: transparent, odorless, tasteless liquid

Boiling: having reached the boiling point

Boiling Water: transparent, odorless, tasteless liquid which has reached the boiling point

If Boiling Water had some other completely different meaning that has nothing to do with the individual words then sure, maybe, otherwise this is completely redundant and opinionated.

Here's an interesting post linked elsewhere in this thread https://taranis.ie/datacenters-in-space-are-a-terrible-horri...
invalidusernam3··on The Overcomplexity of the Shadcn Radio Button
Agree, this kind of complexity is there for a reason. I would rather have a complex component that handles all the cases within its usage in the codebase over having a bunch of little hacks/changes in the usage. It's far easier to maintain one complex component than many different usages of that component.

And you don't have to use such a complex component library if you don't need it. For small codebases it often is overkill. But for large codebases it's a massively worthwhile investment.

invalidusernam3··on N-Body Simulator – Interactive 3 Body Problem and Gravitational Physics
Love the presets! The Broucke one is my favourite
invalidusernam3··on We stopped roadmap work for a week and fixed bugs
I like the idea of this, but why not just have some time per week/sprint for bugs? At my company we prioritise features, but we also take some bug tickets every sprint (sometimes loads of bug tickets if there aren't many new features ready for dev), and generally one engineer is on "prod support" which means tackling bugs as they get reported
invalidusernam3··on AWS multiple services outage in us-east-1
What if the fall-back also never comes back up?
invalidusernam3··on Traffic lights with four colors and a new white light are coming
Public transport is often the fastest way to get around in some cities for some locations. I live in Prague and it's generally faster to take the metro or tram than drive. Obviously not in all cases, but the majority.

Walkable city doesn't mean you can't have a car, it means there are other (often faster) transport options and amenities within easy travel distance without a car. Children and elderly can still be transported by car.

invalidusernam3··on Gmail will no longer support checking emails from third-party accounts via POP
I've been using it for many years, super simple way to have many email addresses deliver to a single gmail. The effort I'll spend migrating will be better spent setting up a non-Google alternative
invalidusernam3··on Imgur pulls out of UK as data watchdog threatens fine
Why would you think that? Leaving the EU was not a geographical event
invalidusernam3··on iPhone Air
I don't really see the point of making phones so thin when the camera sticks out as much as much as the phone is thick. I would rather have a flat phone that is thicker
invalidusernam3··on Ask HN: What are you working on? (July 2025)
I recently launched one of my small side projects. It's quick online multiple choice code tests aimed at recruiters to evaluate applicants: https://hashtagcode.io

The goal was to make a simple way for recruiters to create coding tests to screen people applying for jobs, and to make the process quick and easy for applicants. The default is a 15 minute multiple choice test across a few different domains.

I will eventually monetise it (when I have more free time) but for now it's free (1000 invites) so I can get feedback and improve it

invalidusernam3··on Grok: Searching X for "From:Elonmusk (Israel or Palestine or Hamas or Gaza)"
The "MechaHitler" things is particularly obvious in my opinion, it aligns so closely to Musk's weird trying-to-be-funny thing that he does.

There's basically no way an LLM would come up with a name for itself that it consistently uses unless it's extensively referred to by that name in the training data (which is almost definitely not the case here for public data since I doubt anyone on Earth has ever referred to Grok as "MechaHitler" prior to now) or it's added in some kind of extra system prompt. The name seems very obviously intentional.

invalidusernam3··on Linda Yaccarino is leaving X
What are you basing this on? Because:

https://www.carolinapoliticalreview.org/editorial-content/20...

> the report shows X’s dedication to content moderation by suspending millions of accounts and removing harmful posts, which could potentially help rebuild trust among users concerned with safety and dangerous behavior. On the other hand, this increased moderation contradicts Musk’s earlier promise of promoting free speech, something he has been very vocal about, potentially alienating users who see X becoming more restrictive.

invalidusernam3··on The $25k car is going extinct?
BYD Seagull is $14k in Czech Republic.
invalidusernam3··on Backyard Coffee and Jazz in Kyoto
Regulation is definitely the big stopper in most of the EU. Here in Czech Republic it would be incredibly difficult to open anything like this.

I almost opened a cafe/bar a couple years back, I even had a reservation deposit on a location, had the money to renovate it, had money put aside for it to fully fund the rent and utilities and staff for a year, but in the end I scrapped the idea because of the bureaucracy.

I needed: a hospitality trade license , a certificate from the inspectors for food hygiene and public health, a certificate for fire/gas/electrical safety, registration with the customs office, staff needed to do training for food handling, and I needed to register the kitchen with the regional hygiene office. It's not unreasonable, but it's a lot of bureaucracy for something I wanted to do as a fun side project

invalidusernam3··on Using an $8 smart outlet to avoid brainrot
I've had a time limit set on my phone for twitter + instagram to only allow 15 minutes of usage per day. There's an "ignore limit" button when you go over the time but it's surprising how few times I've actually pressed it. 99% of the time I go "yep, that's enough of that for today" and close the app
invalidusernam3··on Meta's Llama 3.1 can recall 42 percent of the first Harry Potter book
Difference is if it's used commercially or not. Me singing my favourite song at karaoke is fine, but me recording that and releasing it on Spotify is not
invalidusernam3··on AI-designed chips are so weird that 'humans cannot understand them'
One of the junior developers I worked with years ago wrote code that humans couldn't understand, maybe he was was just ahead of his time
invalidusernam3··on Crows and Magpies Snatch Anti-Bird Spikes to Build Their Nests
I witnessed this first hand this spring when a pair of magpies were building a nest in the tree outside my apartment. The tree still didn't have leaves so I could track the progress they made each day. They had a least a couple of anti-bird spikes in their construction (amongst other non-organic materials I couldn't quite make out), but the thing I was most surprised by was the size of the nest, it was huge
invalidusernam3··on Possible association between tattoos and lymphoma
Who cares if others think it's a midlife crisis, do what makes you happy. I'm nearing 40 and still get a couple tattoos a year. I love the feeling of a new tattoo, it boosts my confidence and gives me a sense of accomplishment for sitting through the fairly painful process.
invalidusernam3··on Covid infections are causing IQ drops and years of brain aging, studies suggest
It's not about comparing IQ between countries, it's about pre covid IQ scores with post covid IQ scores within the same country

invalidusernam3··on Is Tetr.io Legal?
I had also never heard of this, so did a bit of googling. Seems to be:

The problem for companies using the .io domain is that it represents the continued oppression of the original people of the Chagos archipelago. All proceeds from the registration of domain names goes to the Internet Computer Bureau, a former British company now owned by Affilias, a US company. Some of the profits from sales were supposed to go to support the territories, but the British government declared it has never received any money for this, and subsequently denied any responsibility for the support of the Chagossian people.

invalidusernam3··on Tesla (VP Vehicle Engineering) says Cybertruck likely to not make it to Europe
I absolutely agree. I live in Prague and a guy on my street owns a Dodge Ram (I think that's what it is, I'm not a car guy). It sticks out far into the street or occupies a large amount of the pavement when it's parked. It struggles to make turns on the narrower roads. I really wish we would ban the import of cars above a certain size, they're dangerous and inconvenient for everyone else in the city.

invalidusernam3··on OpenAI's board has fired Sam Altman
He was saying that if OpenAI was to spend $100 billion on training it would cost $3 a token. I think it's hyperbole, but basically what he is saying is that it's difficult for the company to grow because the tech is limited by the training costs
invalidusernam3··on Show HN: Convert any screenshot into clean HTML code using GPT Vision (OSS tool)
I think they're referring to the video on the github page where it does the generation for YouTube: https://github.com/abi/screenshot-to-code
invalidusernam3··on Copying Angry Birds with nothing but AI
True. Although I did find the writing of prompts to be quite exhausting due to tedium and waiting for the output to be frustrating, so that would dig into my energy for peak coding. I would say it uses less concentration, but about the same amount or even more effort. But also it was a very narrow test, maybe for certain things (especially repetitive code or boilerplate code) it could be very beneficial.
