slau··on PolyDye: Full color printer mod for Marlin 3D printers
You're absolutely right; the real credit goes to the PolyDye project. However, it's TeachingTech's video that made PolyDye explode in the last week. Hackaday is just regurgitating what is explained in TT's video. I guess I'm just a bit tired of that page, and what amounts to basically blog spam.

If I remember correctly, Royal Blue is a PLA blend. Are you using that profile or just Prusament PLA? The temperatures are significantly different (25°C difference), and so are the speeds (20-30% difference).

slau··on Elon Musk wants to block the transfer of InfoWars' X accounts to The Onion [pdf]
It’s not blocked, and there is no improper sale. Well, there is if you listen to Jones.

Jones is alleging that there was fraud and collusion between the Sandy Hook parents/victims and the executor of the sale. The judge will make a decision in a couple of weeks. There are two things being discussed with the judge—Jones’ allegations and a request from the appointee to approve the sale, and the judge has decided to handle both things in a single session.

Jones is trying to delay thing, and spouting a lot of nonsense in the process as usual.

slau··on Lies we tell ourselves to keep using Golang (2022)
Try/catch can bubble through multiple layers. You can decide/design where to handle the errors. If you don't `if err` in Golang, the error is skipped/forgotten, with no way to catch it higher up.
slau··on You too can write a book
Replying to your post-scriptum: maybe it’s used to normalise/re-appropriate[1] the triple parentheses?

slau··on NASA remains silent on why crew went to hospital after dragon splashdown
I believe the issue GP brings up is that merely inhaling a few breaths of this stuff is enough to cause damage. The crew may not have known beforehand that there was a leak or an issue.
slau··on Trump wins presidency for second time
Grover Cleveland would like a word. He won the popular vote 3 times in a row, but lost the EC vote in 1888.

Edit: I’m amazed all 3 replies to the parent comment used the phrasing “would like a word”.

slau··on Ractor – a Rust Actor Framework
I’m not saying that you can’t use another project’s name, but there already exists an actor framework named Ractor, but this one written in Ruby.

slau··on Boston Dynamics robot Atlas goes hands on [video]
I think the exact point they’re trying to make is that a humanoid robot can pick up one shift exactly where a human left off. No custom robotics, no workplace changes, etc.

This is huge for the industry. Smarter Every Day visited a frisbee factory and they had automated a bunch of things. However, every automation point was extremely protected (fenced off) so that a bumbling human couldn’t walk somewhere and get a limb ripped off. If I remember correctly they joked that it was OSHA or something, which it turned out to be.

slau··on 'Sickening' Molly Russell Chatbots Found on Character.ai
For context, 14 year old Molly Russell committed suicide back in '18 after consuming thousands upon thousands of suicide/self-harm/depression pages/articles on FB/IG etc. It is claimed it's the tech giants that pushed that content to her.

Brianna Ghey was murdered in '23 by two 15 year olds.

Character.ai is currently being sued by a mother whose 14 year old son committed suicide after falling in love with one of their AI chatbots.

slau··on 200k subscribers flee 'Washington Post' after Bezos blocks Harris endorsement
They cancel their subscription when the newspaper makes it clear they are no longer independent.

The Post won a Pulitzer for their coverage of Jan 6. The fact they were prevented from endorsing a candidate means Bezos didn’t want them to endorse Harris.

slau··on 50 Years Ago, Sugar Industry Paid Scientists to Point Blame at Fat (2016)
Recycling glass is terribly inefficient. It’s so heavy that it requires a ridiculous amount of energy to heat up, and even then needs a very high amount of “fresh” glass to keep it usable.

In addition, transporting glass is inefficient, and it is much more prone to breakages.

The real issue is the fact that every company gets to have their own plastic bottle design, with 3-4 different plastic types that have to be triaged. They typically also want way thicker bottles than required because they feel more premium.

A government that mandates a specific shared plastic bottle designed to be recyclable would be much, much ecologically effective than switching back to glass.

I don’t know if metal cans or tetrapack are better.

slau··on Do bike lanes cause more traffic congestion? What the research says
I've been wondering the same. To be fair, there were barely any bike lanes in the area I grew up, but roundabouts were legion.

I did explain one technique, where you basically have bikes enter the roundabout and "block" the inner lane as if they were a car, see here: https://news.ycombinator.com/item?id=41924222. I don't know if it's safer or not, but it is one technique that is legal in France since 2015, and an official recommendation to city planners.

Having a cursory look at Google Maps, I see four techniques: move the bike path completely away from the car road, force cyclists to dismount and behave like pedestrians (and use the zebras around the roundabout), allow cyclists to behave like cars and occupy the center lane(s), and the "bike path around the roundabout" technique.

I think both bike-path-around-the-roundabout and forcing cyclists to become pedestrians are equally terrible solutions. Moving the cycle paths away from roads is situational and doesn't really address the crux of the issue. I'll have to try and find more data/experience about the roundabouts that let bikes behave like cars and see how it is. Depending on the roundabout, that must be a harrowing experience.

I think building a pedestrian/cyclist bridge or tunnel could be a solid answer. Or maybe the other way around, because it's still mechanically easier for cars to go up an incline than for cyclists/pedestrians, at the cost of much, much more maintenance.

slau··on Do bike lanes cause more traffic congestion? What the research says
Interesting point of view, but very far from what I said. I think blocking any traffic, be it pedestrian, cyclist or cars is bad.

I would also wager that forcing cycles to cross over car roads is terrible from a safety perspective, exactly because both are going at speed, and both are in each other’s “dead angle”.

In this article[1], they claim 70% of accidents in roundabouts are due to cars not seeing cycles. I do believe that drivers in Copenhagen are by-and-large more acquainted with cyclists popping up, but still. The same article documents an experiment in France where cyclists are invited to occupy the middle lane of the roundabout, and just behave as a car would. It makes them more visible (both by cars in the roundabout and those trying to enter), and removes the number of “exceptions”.

It would most likely slow down car traffic, but that’s fine. The important thing is to not come to an absolute stop.

There’s also a study by CEREMA on how to enable cyclists to utilise and be safer in roundabouts: https://www.cerema.fr/fr/system/files?file=documents/2017/12...

slau··on Do bike lanes cause more traffic congestion? What the research says
I’m not sure it is. 90% of the time it congests on a specific exit—the one going south, and this is entirely due to all the cycles coming from indreby that need to go to the residential area east of that roundabout.

Having grown up in France, I know the insane capacity that roundabouts can have, and I don’t think CPH traffic is anywhere near that. It’s just poor design in some places.

slau··on Do bike lanes cause more traffic congestion? What the research says
The only case where bike paths do generate congestion is when you add them to roundabouts. This is done atrociously in Denmark, effectively negating all benefits of roundabouts—-most likely the reason there are barely any roundabouts in agglomerations.

There is one example in particular (the one between Ørestads Boulevard and Grønjordsvej for any locals reading this). Cycles have right of way, which prevents cars from exiting the roundabout smoothly. At rush hour, this very quickly generates massive queues (in comparison with the amount of traffic), and can sometimes get completely gridlocked.

slau··on Why pay for a search engine
I don’t believe I’ve ever used shopping search. I remember seeing it a decade ago or something, but I never understood the point.

What is it for?

slau··on Why pay for a search engine
Disclaimer: I’m a paying customer of Kagi.

It felt truly bizarre to subscribe to a search engine. To actually pay for access. There’s been a bit of drama with the CEO directly emailing people when they left poor reviews.

Some people are not happy with Kagi investing in browser development instead of search results quality.

I’m not surprised there’s a lot of people having thoughts and feelings about Kagi and expressing them. The fact that there’s a significant overlap between HN and Kagi’s user bases is hardly a surprise either.

slau··on Why pay for a search engine
I’d put it in the “I’m paying for this but I’m not sure the CEO will never make me regret that fact” category.

There’s been some… ego-fuelled decision making happening in Kagi’s communication.

slau··on Show HN: AI-generated images that look like real life
A bunch of the people images are very clearly AI though. I’d wager about 30-50% of them could be recognised as generated by people with a bit of understanding of how these models work.
slau··on Why my apps will soon be gone from the Google Play Store
Doesn't the operating system show you a prompt to show which files you want to give the app access to? From the app's perspective, nothing has changed. It gets a handle to a directory and can list files in it. Whether that directory contains 1 or 10000 items makes no difference.

Just to be clear: I don't disagree with you. I think it's completely normal to have APIs be deprecated, and this means eventually your app will break and be removed from the store. I just don't think this specific example was entirely justified.

I'm a freelance consultant, however I could be convinced to join the right company. For the past 4 years I've been working with a pharma client and getting well versed into GxP software development, including all the documentation and validation that goes into that. I created multiple teams and lead multiple projects for this client. Before that, I've been a VPoE and engineering lead for successful startups.

slau··on America is becoming less "woke"
My partner chaired a D&I board for a while. The amount of work she had to put in was astonishing.

She organised events, had to find speakers, find venues for said events, wrote internal SM posts, etc.

And this was all unpaid, effectively. There was no policy, no obligation to participate, no forced anything. It was just about creating space that can either accommodate discussions or promote awareness, or workshops to help some people be inspired, feel supported or encouraged. There were culture cafés, mentoring programs, etc.

Said company seems to have had a reduction in DEI efforts/positions, but that seems aligned with a general cost reduction, not because DEI was a failure.

(I do an exceptionally poor job of summarising what she did, but then again, I wasn’t directly involved in it).

slau··on Ask HN: Is distributed systems research slowing down?
Maybe there was an edit, but I don’t see how OP said anything was due to AI. They’re just asking whether distributed systems aren’t even more relevant today than during the 90s or 2000s as it seems AI could benefit from being distributed.
slau··on Boy named after Star Wars character denied passport due t copyright infringement
The second article, about the GoT character, is a big nothing burger:

> With fears it could affect her daughter’s future travel, the family sought legal advice over the passport rejection.

> They found while there is a trademark for Game of Thrones, it does not apply to a person’s name.

> The family then sent that information back to the Passport Office to clear up the issue.

> The Passport Office has since apologised to Lucy and her family, labelling the rejection a “mistake” and claimed there was a misunderstanding between guidance staff.

slau··on Master Hexagonal Architecture in Rust
I agree that a duplicate key problem is 409. However I disagree that 422 is for encoding issues. Quite the contrary, 422 specifically says that “the server understood the content type of the request entity, and the syntax of the request entity was correct, but it was unable to process the contained instructions.”[1]

So it’s more “your request didn’t make logical sense” more than “your request was missing a closing bracket”. That’s just a 400.
