rwz··on Ask HN: Claude multisession
I personally use the herdr tool and recommend it.

rwz··on The AI bubble is popping; we just don't know it yet
> So take robots: I can promise you that you won't see robotics in every household in the next decade (especially so if we exclude the current market of robot vacuums).

People in 2016 were adamant that the current frontier LLM capabilities would not be achievable in the next decade.

Modern home robots prototypes look awkward and mostly useless the same way GPT-2 was looking like a curious but mostly useless thing in 2016.

I can totally see a capable and affordable home robots that are worth buying for the majority of the population being a reality by 2036. Maybe not _every_ household, but a good number of them.

rwz··on Ten advances in mathematics and theoretical computer science

I think recognizing and accounting for your own personal biases is one of the requirements of the being an intellectually honest and rigorous online discourse participant.

Things could be genuinely impressive and fascinating even when directly challenge your ego and material well being.

rwz··on An internal OpenAI Astra model solved 10 major open math and CS problems
If everybody is "valued", nobody is.

The concept of value implies exclusivity by design.

rwz··on Run Kimi K3 using 29 GB of RAM at 0.50 tok/s
0.5t/s is still too slow even for email. For a moderately large inquiry (1MTok output, let's ignore the 4k context window limitation for now) it'll take the model around 23 days or uninterrupted execution to answer a single email.

Real world inquiries are gonna be much slower of course, but this setup is still too slow to do anything meaningfully useful I think.

rwz··on Canceling "Hey"
Not that I disagree, but to play Devil's advocate for a second...

I think DHH was trying to refer to junkies and homeless people most of whom happen to be immigrants. The immigration status is the particular attribute that invites usage of the term "gypsies" to signal that the problem with those particular junkies and homeless could be solved via immigration enforcement. At least in his eyes, I presume.

Again, not defending his choice of words, just providing a somewhat plausible explanation as to how one might arrive to this specific terminology.

rwz··on Canceling "Hey"
I don't know about Copenhagen, but in US a significant fraction of the homeless population openly rejects various shelter and housing opportunities because those usually come with extra requirements for sobriety and commitments to addiction treatments. So yeah, there's definitely people who just refuse to go.

Then there's also mentally ill people who operate in the grey zone of law — clearly too mentally ill to be prosecuted for their crimes (or haven't committed any crimes yet), can't be held in prison, but also too unstable and violent to be admitted to shelters with other, mostly normal disadvantaged people.

One example of such case: https://en.wikipedia.org/wiki/Killing_of_Eina_Kwon

rwz··on Turn And Face The Strange
> What are we doing here? What’s going on?

Lol, did not expect a Tucker reference in my devex startup pivot blog post annoucement.

rwz··on AIs don't do what you want. This is bad
A toaster is not capable to supplement or even replace your social circle. AI chatbot is.

Definitely not advocating for this, but it's actively happening.

https://www.reddit.com/r/MyBoyfriendIsAI/

rwz··on AIs don't do what you want. This is bad
People don't treat violent videogames as boyfriends. They do it to chatbots. Merits and sanity of this type of behavior aside, it's actively happening and we have learn how to live with it and deal with consequences.
rwz··on AIs don't do what you want. This is bad
I don't think it's realistically traceable or attributable. But plenty of people these days supplement or even completely replace their social needs with AI chatbots (AI friends/boyfriends/girlfriends etc).

People like that would calibrate their social skills and interactions based on the AI reaction and having AI just take all the abuse without any pushback would train them to be insufferable assholes as their social baseline.

rwz··on AIs don't do what you want. This is bad
Sure, but I'm not sure allowing AI agents to act as abuse sponges for troubled people enabling them to spiral into their unhealthy habits is good idea that would lead to great outcomes long term.

So I'd rather take LLM pretending to be offended over the alternative.

rwz··on What if we made advertising illegal?
I'm blown away by author's refusal to spend even a second to adversarially pressure-test his idea and try to imagine for a second what the world would realistically looked like with advertisement banned.

Like, the movie industry as a whole cannot exist without advertisement. Nobody would spend hundreds of millions of dollars on production of the scale of Odyssey, if there's no way to communicate to enough people about the movie's existence so they could come to a theater on a given date and pay to watch it.

How can someone take risks and spend time and capital inventing or building a new product if there's no reliable way to let potentially interested people know about it other than word of mouth? What about antisocial people who don't have friends and prefer to not talk to strangers? How are they supposed to ever find out about new shit that could change their lives?

Am I allowed to walk around saying "I really like product X" out loud? If not, then it feels like a freedom of speech problem. If yes, how can you be sure I'm not financially or some other way incentivized to do so by the company producing product X?

The fact that the author doesn't even attempt to engage with any of these questions makes articles like these really infuriating to read.

rwz··on I regret migrating to Codeberg
> It's not all that different from Mastodon instances. It's a community space, and the community gets to decide who they allow to use their resources. Personally, I have a group of friends who share a GitLab instance, for example.

I think it's a bad example since your private GitLab instance wasn't all over the HN earlier screaming "are you tired of Github outages and Microslop breaking it every day? Migrate all your shit to Codeberg, the good guys of the internet" only to later pull the rug like this.

Private stuff is cool and there's place for it. Codeberg was actively positioned as an indie almost drop-in Github alternative and it's currently failing miserably at this.

rwz··on Codeberg Bans Cryptocurrency Projects
Yeah, I'm not interested in a service that makes their product decisions based on the political hot button issue of the day. Was it only yesterday when they decided to ban "vibecoded" projects? Nobody in comments had a clear idea on what exactly the definition of "vibecoded" is, so half of the discussion was just confusion.

Now it's this.

I want my code hosting to host my code and only consider removing something when there's a legal demand from authorities.

Otherwise you can't be sure that the code you host peacefully today won't fall out of political activists favor tomorrow and be deleted forcing you to scramble figuring out where to move to. Fuck this.

rwz··on Israeli spyware vans infiltrate American streets and your phones
That's your conjecture, the article does not make such claims.
rwz··on Israeli spyware vans infiltrate American streets and your phones
That's not the point. The point is that the title makes it seem like the Israeli's government is spying on you, while what the article really says is that US is buying Israel's tech to spy on its own citizens.

The title misrepresents the article claims.

rwz··on Over 400 Linux CVEs published in the last 24 hours alone
Good, it seems like new AI tools would lead to substantially more hardened Linux kernel long term. Until a new generation of AIs finds more bugs.
rwz··on Claude Code uses Bun written in Rust now
> Nope, this is demonstrably false because Rust has its own invariants around its types and the codebase is violating a lot of them.

I'm not sure I'm following what you're saying here. In the rewrite blog post it has been stated that the Rust port landed in a place where it passes 100% of the existing test suite and does so without some of the known memory leaks of the Zig version that they were aware of and didn't know how to address.

Sure, there's no guarantee that the port didn't introduce new bugs and most likely it did, but the 1.4 version has not been released yet, so I don't think a direct comparison of a long-time "stable" version and the just-landed full rewrite is meaningfully helpful.

> "Potential memory issue" can originate in unsafe blocks and safe code that are able to alternate the input condition of these unsafe blocks. Guess what? That still counts towards 100% in this code base, hence the abomination remark.

But that just means that once you get rid of the unsafe block, you're pretty much guaranteed by the Rust compiler to be memory-safe. This means that all your potential memory landmines are annotated in the code and once you disarm them all, you're memory-safe.

I don't understand how what you're saying contradicts any of my statements.

> Not as easy as it sounds. They are like threads in a yarn ball, if there are one or two ends visible it's easier to sort them out.

Still easier than the Zig version, where all the same things you've mentioned apply, but also there's no visible indication of progress and issues are unmarked and could be pretty much anywhere.

> It's too early to declare it as anything remotely close to a win, optimistically saying.

Based on the rewrite blog post it's pretty clear that the Rust version is outperforming the Zig version by pretty much every measurable metric at this point.

I think the backlash is mostly focused on the ideological opposition to fully AI-authored 1MLOC+ PR approach they took.

rwz··on Claude Code uses Bun written in Rust now
The original code was one giant unsafe block with almost no tangible way to find or debug all the subtle memory bugs and leaks they had.

Now it's smaller, faster and has fewer bugs. Also its every potential memory issue is neatly annotated by an unsafe block so you can go and refactor them out one by one with confidence.

All this seems like a pretty huge improvement to me. Why is this an abomination in your eyes?

rwz··on Save GPT-5.5
People getting emotionally attached to non-openweight models must be having it rough these days. I personally never understood the concept, but sucks to be them.

Unrelated, but, it seems that "I wrote this myself without any AI help" has firmly established itself as an excuse for shitty incoherent writing at this point.

rwz··on How Our Rust-to-Zig Rewrite Is Going
> they want to be able to make breaking language changes

That sounds like it's not ready for production to me.

rwz··on To decarbonize we must decomputerize: why we need a Luddite revolution
Mobile safari does support adblocks. https://1blocker.com/ seems to be the one most people recommend (I personally haven't tried it)
rwz··on Anti-Putin Politician Facing Kremlin Raid Uses Drone to Fly Hard Drives Away
Hell no. It's even crazier and more blatantly unfair since there's less monitoring and less need to save face and maintain the illusion of fairness.
rwz··on Show HN: Thread – Ad-free social networking and iMessage alternative
I like the effort, but honestly there's tons of apps that are cross-platform, free, and can do everything imessages can, but better. Telegram is just one example.

I see adoption as a biggest problem. I personally tried to migrate to Telegram and failed to convince even my own wife to give it a try, since imessages work for her and all her friends are there and why bother.

rwz··on BMW unveils car sprayed with Vantablack
I don't share the resentment towards BMW X6. I actually think it's the best looking BMW SUV. To each their own I guess.
rwz··on BMW unveils car sprayed with Vantablack
Cars are a really weird choice of consumer products to paint in vantablack. All the aesthetics of rigid car body shapes are obscured and you can't really appreciate it. Not to mention how impractical such a car would be.

I totally understand that this is an artistic concept and nobody is planning to mass-produce or sell those, but still.

What I really wanna see in vantablack is clothing. I think it'd look really interesting and eye-catching.

rwz··on Let's build houses for people, not cars
I'm not arguing about that and not trying to call it a success. I'm just stating that taking away roads does in fact make cars less convenient.
rwz··on Let's build houses for people, not cars
Well, it actually does.

The convenience of a car is determined by how likely you choose a car over other means when you need to get somewhere. If there's less roads, you're less likely to choose car, thus the lowering the convenience factor. If there's no roads at all, owning a car is meaningless since you can't drive anywhere, and its convenience is pretty much zero.

rwz··on Swatting Is a Deadly Problem–Here's the Solution
No, I get the necessity of deployed armed SWAT units every time there's a risk of gun violence and stuff, I don't understand why an anonymous call warrants such a response.

I wonder if there's some kind of metrics available breaking down how often an anonymous calls amount to something real vs abuse of system.
