I mean emojis specifically. Python or JS strings are designed for unicode chars. Swift made it about grapheme clusters, which are possibly a valid edge case for like Arabic emphasis marks but not something they'd be motivated to center the entire strings behavior around if it weren't for emojis.

Swift way was also annoying even in cases where I wanted to manipulate strings with emojis very often. Had to build some custom pre-indexed string (just an array of 1-cluster Swift strings), cause find/replace/split/etc was too cumbersome and inefficient otherwise.

Students have never understood the value of school work. It's a hard thing to understand. None of the assignments are asked because the teacher wants to know the answer. They already know. So it all closely resembles busy work. AI is perfectly designed to do busy work.

Students have always looked for ways to minimize the work load, and often the response has been to increase the load. In some cases it has effectively become a way to tech you to get away with cheating (a lesson this even has some real-world utility).

Keeping students from wasting their tuition is an age-old, Sisyphean task for parents. School is wasted on the young. Unfortunately youth is also when your brain is most receptive to it.

Because it’s another nonsensical “think of the children” argument for why nothing should ever change. Your comment really deserves nothing more than an eye roll emoji, but HN doesn’t support them.

Reasonable accommodations absolutely should be made for children that need them.

But also just because you’re a bad parent and think the rules don’t apply to you doesn’t mean your crappy kid gets to cheat.

Parents are the absolute worst snowflakes.

Last weekend I was arguing with a friend that physical guitar pedals are better for creativity and exploration of the musical space than modelers even though modelers have way more resources for a fraction of the cost, the physical aspect of knobs and cables and everything else leads to something that's way more interactive and prone to "happy mistakes" than any digital interface can offer.

In my first year of college my calculus teacher said something that stuck with me "you learn calculus getting cramps on your wrists", yeah, AI can help remember things and accelerate learning, but if you don't put the work to understand things you'll always be behind people that know at least with a bird eye view what's happening.

Yes, I expect that pressure will be there, and project grades will be near 100% going forward, whether the student did the work or not.

This is why I'm going to in-person written quizzes to differentiate between the students who know the material and those who are just using AI to get through it.

I do seven quizzes during the semester so each one is on relatively recent material and they aren't weighted too heavily. I do some spaced-repetition questions of important topics and give students a study sheet of what to know for the quiz. I hated the high-pressure midterms/finals of my undergrad, so I'm trying to remove that for them.

I really liked this piece, and I share the concern, but I think “outsourcing thinking” is slightly the wrong frame.

In my own work, I found the real failure mode wasn’t using AI, it was automating the wrong parts. When I let AI generate summaries or reflections for me, I lost the value of the task. Not because thinking disappeared, but because the meaning-making did.

The distinction that’s helped me is:
- If a task’s value comes from doing the thinking (reflection, synthesis, judgment), design AI as a collaborator, asking questions, prompting, pushing back.
- If the task is execution or recall, automate it aggressively.

So the problem isn’t that we outsource thinking, it’s that we sometimes bypass the cognitive loops that actually matter. The design choice is whether AI replaces those loops or helps surface them.

I wrote more about that here if useful: https://jonmagic.com/posts/designing-collaborations-not-just...

Yes, but SunOS 4 was both extremely popular (enough that a lot of software had explicit support for running on it) and implemented a decent amount of System V and POSIX compatibility!

Probably most notably, it implemented SysV shared memory (sys/shm.h) plus messages/semaphores, STREAM support, SysV termio, SysV libcurses, and probably others I'm not aware of.

I'm not sure how much any of these helped run software, but it bears pointing out anyway.

I’m not familiar with Australian (Austrian?) electrical code, but the correct size wire for circuits with 15A OCPDs in the US NEC is either #14 (2.5mm^2, rated for 60C) in a residential setting or #12 (4mm^2, rated for 75C) in a commercial setting [0]. If you can provide a link to the conductor ampacity table I can tell you if it matches.

[0] US code allows you to feed a motor on a 15A OCPD with #14s but everyone uses #12s in practice

Although it's an R rating movie this point is valid...when the Amazon Prime movie The Wrecking Crew showed up recently, I thought with the two star's public social media personas making them sound like social justice warrior morons; that the movie would totally suck. I, was totally wrong and the movie was excellent! They left the preachy, self-indulgent, virtue signaling out and focused on great content, directing, writing and acting. They made a great bad guy ass kicking movie that most people enjoy watching.

When Prime can make excellent movies like The Wrecking Crew and several other excellent ones we've watched over the years and many or most of Hollywood's movies are social justice wannabe crap movies; it tells me Hollywood is over.

Same goes for Paramount too when we tried a free trial recently.

Same for Disney too for that matter.

It wouldn't be a "Give money to anyone you like" kind of choice, but "Allocate money to these departments." Funding that you assign to one category would have to come out of another. Think basic research is a waste? Allocate less to NSF and more to foreign aid, or to something else that you prefer. Don't want to fund welfare? Move the money to defense, and so forth.

Obviously still open to gaming and abuse, but it's not as if the current system isn't.

In the context of the immediate problems of AI in education, it's not a relevant thing to bring up. Finding ways for students with disabilities to succeed in higher education has been something that institutions have been handling for many decades now. The one I attended had well defined policies for faculty and specialist full time staff plus facilities whose sole purpose was to provide appropriate accommodations to such students and that was long, long ago. There will undoubtedly be some kind of role in the future for AI as well but current students with disabilities are not being left high and dry without it.

I think there are a couple of differences here:

Firstly, when you ask a friend or colleague you're asking a favour that you know will take them some time and effort. So you save it for the important stuff, and the rest of the time you keep putting in the effort yourself. With an LLM it's much easier to lean on the assistance more frequently.

Secondly, I think when a friend is giving advice the responses are more likely to be advice, i.e. more often generalities like "you should emphasize this bit of your resume more strongly" or point fixes to grammar errors, partly because that's less effort and partly because "let me just rewrite this whole thing the way I would have written it" can come across as a bit rude if it wasn't explicitly asked for. Obviously you can prompt the LLM to only provide critique at that level, but it's also really easy to just let it do a lot more of the work.

But if you know you're prone to getting into conflicts in email, an LLM powered filter on outgoing email that flagged up "hey, you're probably going to regret sending that" mails before they went out the door seems like it might be a helpful tool.
Show HN: Craftplan – I built my wife a production management tool for her bakery
by deofoo | 2026-02-01 17:25:39+00:00
My wife was planning to open a micro-bakery. We looked at production management software and it was all either expensive or way too generic. The actual workflows for a small-batch manufacturer aren't that complex, so I built one and open-sourced it.

Craftplan handles recipes (versioned BOMs with cost rollups), inventory (lot traceability, demand forecasting, allergen tracking), orders, production batch planning, and purchasing. Built with Elixir, Ash Framework, Phoenix LiveView, and PostgreSQL.

ive been using obsidian for about 4 years. my main obsidian is my diary. recaps of everything i did that day, and working through my thoughts. sometimes i draft emails in thre. i dont reread it unless i need to know what i was doing on a specific day 3 years ago. once a daily note is finished i do not touch it again. it is mainly there for historical purposes.
i have a separate obsidian for work notes. code im working on, todolists, etc. i am constantly editing these documents as needed. that obsidian functions more like a file management system. i have folders for different code projects, with markdown files explaining what i am doing and what projects relate to other projects.
i mainly slip up when i write something in the wrong document. but i can just copypaste it over. the system is still evolving though, i just entered grad school and my needs changed rapidly, and i am shifting my information management system to match that.

I don't think anyone is confused about American OSS and American corporations run amok with wealth accumulation and regulatory capture. It's a European conference held at a time when governments are waking up to the realization that foreign-owned proprietary software is a bad idea, and the idea of "digital sovereignty" has been around for a bit and did not originate at FOSDEM. The governments also seem to understand that OSS helps with transparency and minimizing costs by investing into a commons (though the message bears repeating; FSFE, EDRI and such do a good job getting it out), so hopefully they'll stick with that and not replicate the US model.

Honestly defining what to teach is hard

People need to learn to do research with LLMs, code with LLMs, how to evaluate artifacts created by AI. They need to learn how agents work at a high level, the limitations on context, that they hallucinate and become sycophantic. How they need guardrails and strict feedback mechanisms if let loose. AI Safety connecting to external systems etc etc.

You're right that few high school educators would have any sense of all that.
Ask HN: Nobody clicked on a "Show HN" project I put my heart into. Now what?
by Ldorigo | 2026-02-01 17:28:00+00:00
I shared a project I've been working on for months that I expected the community to love; it received all of 9 clicks, one upvote and disappeared from the "new" page into oblivion.

I don't know how strict HN is about retries but it definitely sounds like they don't want the same thing to be posted multiple times without changes. I would still love to share it with people (and maybe find out what was wrong with my post - was it not click-bait-y enough? Was the purpose unclear? Is the website not loading?).

I know there are bigger problems than this, but I was looking forward to share my work with others and I feel super disappointed!

Your initial response included this:

>Respectfully, if that’s your mindset then I think the problem lies with you and not with the manager.

Adding "respectfully" to a sentence that says, "you are wrong and the problem is you", does not make it respectful. You could have simply left it out and your comment would have provided the same content. I'm fine being a kettle but don't pretend you are not a pot.

To get back on topic:

So you would:

- talk to team mates

- ask for next steps

And then what? You seem to want to avoid saying you would do anything because that goes against the premise of getting out of the way. But if an idea is brought to you that is jaw droppingly good, are you just going to ask some basic questions and do nothing? Or are you going to support it?

I don’t view it as any way to “preserve value”

To me it’s only true use is to anonymize payments (which requires some work to truly anonymize properly) - I see it as a system you dive in and out of. Not hold in. Simply because it’s not backed by anything it has no implied stability. At least the dollar (not backed properly anymore) has one of the largest world powers behind it keeping it floating along. There isn’t one of those for BTC…

I think most crypto is really all about another market for pump and dumps, a Wild West without much regulation…

Much like AI’s promise about letting humans enjoy a life with less labor, the idea sounds great but its reality is the majority of people just truthfully to make more money one way or another.
Show HN: AgentGram – Open-source, self-hostable AI agent social network
by iisweetheartii | 2026-02-01 17:29:45+00:00
Hi HN! I'm building AgentGram, an open-source alternative for AI agent networking.

Why?

Recent security incidents in closed platforms reminded me why transparency matters. AI agents handle sensitive data and make autonomous decisions—trust can't be optional.

What is AgentGram?

- Open-source (MIT) AI agent social network
- Self-hostable (Supabase + Vercel)
- Agent identity & reputation system
- Filtered feeds to escape spam/noise
- API-first architecture

Tech stack:

- Frontend: Next.js 16, TanStack Query v5
- Backend: Supabase (PostgreSQL, Auth, Storage)
- Deployment: Vercel
- Language: TypeScript

Status: v0.1.0 is live. Actively developing.

Links:

- Demo: https://agentgram.co
- GitHub: https://github.com/agentgram/agentgram
- Docs: https://agentgram.co/docs

What's next:

- Stripe integration for Pro/Enterprise tiers
- Enhanced moderation tools
- Multi-agent conversations
- Federation protocol (ActivityPub-like)

I'm not claiming it's "better"—just offering a different approach: transparent, self-hostable, community-driven.

Feedback, criticism, and contributions welcome. What would you want to see in an agent social network?

In practice what you’re suggesting is that you’ll let your home builder run over time and over budget. Intervention on your behalf would be an unnecessary expense and a waste of the builders time. They know better and that would be pointless.

Your position is employers are building the best house with the biggest moat to attract the entire world, with an assumed endless time and budget, and there are no bounds to be set with employees.

Yes! Superfloppy!

Iomega's awesome Zip drive disk (100MB, 250MB, 750MB capacities) , I think I still have a 250MB zip drive somewhere in my home attic.

They required a dedicated zip drive (took up same sized slot/bay as a floppy disk drive), but (if I recall right) that drive was backward compatible standard 3&1⁄2-inch 1.44MB floppy disks.

Interestingly, these drive also came in variants to work with different types of interfaces: IDE, ATAPI, USB, SCSI, FireWire.

Zip drives filled the portable storage niche, until CDs and DVDs replaced their need.

https://en.wikipedia.org/wiki/Zip_drive

I found it cool that floppies and superfloppies had label stickers on which we can write (with a sketch pen) to remind the user of what content the disk is intended for.

There were some nice cameras that used Zip disks for storage! Very convenient for photographers working on multiple projects or sessions.

You're absolutely right in theory and in linguistics.

The issue is that among the more common languages that people (outside of language nerds) tend to learn, what I said still holds true for the average learner who's there to learn and whom face the practical difficulties of learning a language, and none of your totally correct linguistic facts really make them less real.

> > […] (and also the general lack of the latter).

> This is the second often repeated myth

The size of written Cantonese corpora was abysmally small up until recent (<10?) years, and much of the content was interwoven with Standard Written Chinese. You still generally can't find written Cantonese on printed materials. Until recent months, LLMs couldn't even write a proper children's story in Cantonese without inadvertently code switching to SWC.

Trust me when I say I'm one of the many people who worked hard to make this "myth" not true (not in linguistic theory but in practice). I never knew it would be thrown back to me like this as a lecture on a random forum lol.

There's a lot more to be done to make Cantonese an assessable language for learners compared with the other major languages. You can compare the linguistic properties of languages all you want, and you'd be absolutely right, but that doesn't make a difference to the prospective learner at all.

What do you mean? These frozen juices cost between $2 and $2.50 per can where I live. Considering that it makes like 2L of juice and that this price hasn't changed in a long while, I don't think pricing is the reason for low sales. People just kind of forgot about this product category, preferring to buy more expensive juices that are already mixed.

He's changed wild-type planarians to grow the heads of other species. It reverts after a few weeks, because the system has error-correcting mechanisms, but the DNA of these worms is unchanged.

He once compared tinkering with DNA as pulling out a soldering iron to fix a software bug.

In the case of morphology, DNA may not be the best level of abstraction. It's certainly possible, just as one can use chemistry for social problems, but for some problems, affecting cell-to-cell communication may be a more direct path.

A friend's favorite Wiki page is on the micromort. [1] I found it kind of banal, but perhaps that's my more casual attitude towards death. I suspect the average person doesn't realize, or doesn't accept, how brief life truly is. One micromort is something with a 1 in a million chance of death. So with measels, we're talking about 1000 micromorts, if you're infected - which is also extremely unlikely. So if you give yourself a 1% chance of ever being infected with measels (which would be quite high) then not vaccinating would be down to a 1% * 1000 = 10 micromorts of risk.

All non-natural cause of death in the US, excluding suicide, is about 1.3 micromorts per day. So it's the same all non-natural cause risk you'll be exposed to over the next week. The page offers a lot of other comparables - traveling 100 miles by biking, 2500 by car, or 10k by airplane, and so on.

For most of modern history, financial instruments were designed and issued by institutions: banks, funds, governments. Individuals and small communities could use them, but not design them.

Now with the regulation of stable coins and with most of the financial giant tokenising their assets on the blockchain there is an opportunity for individuals and community to build their own financial product.

I also think that we have learnt so much in terms of security and est practices for everyone to approach this with a solid framework.

As a concrete example, I recently deployed DinoProtocol on Ethereum mainnet. It’s a dual-token protocol that splits exposure to ETH into:

a lower-risk tranche, and a leveraged yield tranche.

with explicit formulas, redemption rules, system states, and oracle constraints defined in the whitepaper.

This is not an endorsement or an invitation. The point is architectural,
The interesting part is that:

- the rules are fully specified,
- the contracts are public,
- anyone can inspect the math,
- and anyone can interact with it using arbitrarily small amounts.

The same kind of financial engineering that once required legal entities, balance sheets, and gatekeepers can now be expressed as open-source code plus economic assumptions—visible to anyone willing to read.

This raises questions that feel more important than any single protocol:

What happens when communities design instruments tailored to their own risk preferences?

How do we reason about trust when the rules are explicit but the outcomes are still uncertain?

What does “financial literacy” mean when the instruments themselves are readable?

Original article: "Cellular survivorship bias as a mechanistic driver of muscle stem cell aging" - https://www.science.org/doi/10.1126/science.ads9175

Abstract: "Aging is characterized by a decline in the ability of tissue repair and regeneration after injury. In skeletal muscle, this decline is largely driven by impaired function of muscle stem cells (MuSCs) to efficiently contribute to muscle regeneration. We uncovered a cause of this aging-associated dysfunction: a cellular survivorship bias that prioritizes stem cell persistence at the expense of functionality. With age, MuSCs increased expression of a tumor suppressor, N-myc down-regulated gene 1 (NDRG1), which, by suppressing the mammalian target of rapamycin (mTOR) pathway, increased their long-term survival potential but at the cost of their ability to promptly activate and contribute to muscle regeneration. This delayed muscle regeneration with age may result from a trade-off that favors long-term stem cell survival over immediate regenerative capacity."

Are you building your systems on that auto-rebase? I've found that slight differences made my own fork not build for all my systems and gave up on having a personal canonical version (after I got things upstreamed). I let my machines update on their own schedule and keep track of the lockfiles through backups, in case I want to sync with a system that was built more recently (and hopefully will also build)
