That's obviously not true. You can do anything you want with a sandbox. Open a socket to the OpenAI servers and then pass that off to the sandbox and let the sandboxed process communicate over that socket. Now it can talk to OpenAI's servers but it can't open connections to any other servers or do anything else.

The startup process which sets up the original socket would have to be privileged, of course, but only for the purpose of setting up the initial connection. The running LLM harness process would not have any ability to break out of the sandbox after that.

As for spawning unsandboxed processes, that would require a much more sophisticated system whereby the harness uses an API to request permission from the user to spawn the process. We already have APIs like this for requesting extra permissions from users on Android and iOS, so it's not in-principle impossible either.

In practice I think such requests would be a security nightmare and best avoided, since essentially it would be like a prisoner asking the guard to let him out of jail and the guard just handing the prisoner the keys. That unsandboxed process could do literally anything it has permissions to do as a non-sandboxed user.

Who is behind this over digitization of primary school? My understanding is that in the Us pretty much all homework and tests are done on computers or iPads.

This obv isn’t a push by parents because I can’t imagine parents I know want their kids in front of a screen all day. At best they’re indifferent. My only guess is the teachers unions that don’t want teachers grading and creating lesson plans and all the other work they used to do.

And since this trend kid scores or performance has not gotten better, so what gives?

Can anyone comment if it’s as bad as this and what’s behind it.

The luddites food requirements didn’t provide them with popular support.

Similarly US agricultural output could be cut in half without serious negative consequences. Far more corn ends up as ethanol than our food and we export vast quantities of highly subsidized food to zero benefit. Hell ethanol production costs as much in fossil fuels as we get ethanol from it, it’s literally pure wasted effort.

Rational policy would create a large scale food shortage and then let market forces take over. We could have 10 years of food on hand for every American at way less expensive than current policy with the added benefit of vastly reducing the negative externalities of farming such as depleting aquifers.

A recent thought:

It might interesting to set up an open source group that provides an ecosystem of re-usable tools and libraries that interoperate well, and solve problems that are otherwise solved with with repetitive flakey internal implementations by several players in an industry.

Sort of like Apache Software Foundation, Spring Framework (for java), Boost (for c++), but higher level and industry-specific, e.g. for finance, some libraries and tools for handing FIX protocol, parsing file formats from market data vendors, also tooling for change management / releases etc. I am sure each industry has its collection of common use cases, like geology tools/libraries for mining, or handling genetic data for bioinformatics/pharma, etc.

The group, though, should have a corporate-friendly outward branding, be composed of people actually working in the industry, and somewhat selective with membership. A goal, perhaps not mentioned on the website but known to members, would be that the organization exists for the benefit of its members getting hired in the industry, consulting work, hiring each other when practical, books, training, etc. on using the libraries and tools.

In a way, it's really not anything too original, and I am sure close to how many open source groups have always operated in practice, crossed with a something like a guild/union/professional network. The main thought would be to do this for what seems like a "missing middle" of industry-specific stuff where there are maybe tens or hundreds of potential client companies, so not totally generic like kernels/compilers/spring/boost, but not a big enough market to attract a VC backed company, but big enough to offer cushy jobs for a few dozen people who would never have to do leetcode interviews ever again.

You don't have this? In Sweden we have sensors to detect cars, pedestrians and bicycles to shift the lights as appropriate. During rush-hour those features are turned off/discarded in favor of "grid optimized" timings. In Netherlands they prioritize pedestrians and cyclists when it's raining.

We also have LED lights in our traffic lights which I've come to understand is a saftey hazard in USA because snow falls sometimes.

> The parties want an "enforceable European minimum age of 15 for social media, with privacy-friendly age verification for young people, as long as social media are not sufficiently safe

I will never trust that a solution will actually be privacy friendly. Even if someone could imagine a technical path to it, I just don’t trust governments to care about privacy. Eventually it’ll mean that we can’t speak online with anonymity.

Well... As one of those supposed 10x engineers, that's not quite true

It's true that the intellectual satisfaction is my main driver, but I'm also quite vain. Appreciation and respect (especially from peers, who cares about an All Hands) add juice to the battery.

It would be like if I was expected to deliver A by the end of the quarter and instead I delivered A + B. The value gain from B was more than A. Your manager (and hopefully higher up the org) better know about B, or they will attack it as a threat.

Also, I’m not being paid for my time, I’m being paid to do a job. “Trading your time for money” is one of the most self defeating views on work you can have. It reduces you from a worker with agency to a detached prostitue, and is harmful to both the employer and employee.

The students were reading AI summaries rather than the original text.

Does this literally work? It adds slightly more friction, but you can still ask the robot to summarize pretty much anything that would appear on the syllabus. What it likely does it set expectations.

This doesn't strike me as being anti-AI or "resistance" at all. But if you don't train your own brain to read and make thoughts, you won't have one.

If you are flipping through the reading to find a quote, then printed readings are hard to beat, unless you can search for a word with digital search. But speed reading RSVP presentation beats any kind of print reading by a mile, if you are aiming for comprehension. So, it is hard to say where the technology is going. Nobody has put in the work to really make reading on an iPad as smooth and fluid as print, in terms of rapid page flipping. But the potential is there. It is kind of laughable how the salesman will be saying, oh it has a fast processor, and then you open up a PDF and scroll a few pages fast and they start being blank instead of actually having text.

Main reason I haven’t switched over to the new pi coding agent (or even fully to Claude Code alternatives) is the price point. I eat tokens for breakfast, lunch, and dinner.

I’m on a $100/mo plan, but the codex bar makes it look like I’m burning closer to $500 every 30 days. I tried going local with Qwen 3 (coding) on a Blackwell Pro 6000, and it still feels a beat behind, either laggy, or just not quite good enough for me to fully relinquish Claude Code.

Curious what other folks are seeing: any success stories with other agents on local models, or are you mostly sticking with proprietary models?

I’m feeling a bit vendor-locked into Claude Code: it’s pricey, but it’s also annoyingly good

While I fully agree with this, this quote bothers me:

>Shorter packets can cost around $20, while longer packets can cost upwards of $150 when ordered with the cheapest binding option

Does a student need to print out multiple TYCO Packets ? If so, only the very rich could afford this. I think educations should go back to printed books and submitting you work to the Prof. on paper.

But submitting printed pages back to the Prof. for homework will avoid the school saying "Submit only Word Documents". That way a student can use the method they prefer, avoiding buying expensive software. One can then use just a simple free text editor if they want. Or even a typewriter :)

I have mentioned this in a few comments: for my CS classes I have gone from a historical 60-80% projects / 40-20% quizzes grade split, to a 50/50 split, and have moved my quizzes from being online to being in-person, pen-on-paper with one sheet of hand-written notes

Rather than banning AI, I'm showing students how to use it effectively as a personalized TA. I'm giving them this AGENTS.md file:

https://gist.github.com/1cg/a6c6f2276a1fe5ee172282580a44a7ac

And showing them how to use AI to summarize the slides into a quiz review sheet, generate example questions with answer walk throughs, etc.

Of course I can't ensure they aren't just having AI do the projects, but I tell them that if they do that they are cheating themselves: the projects are designed to draw them into the art of programming and give them decent, real-world coding experience that they will need, even if they end up working at a higher level in the future.

AI can be a very effective tool for education if used properly. I have used it to create a ton of extremely useful visualizations (e.g. how twos complement works) that I wouldn't have otherwise. But it is obviously extremely dangerous as well.

Oh god, I hope I read this wrong. I thought Rust finally fixed C/C++'s worst issue which is aliasing, which means that if you pass a struct by pointer to a function, since any number of other mutable references might exist to it, the only correct way to treat it, is to reload/save it to memory every time you access it.

This is obviously unacceptable from a performance point, so compilers have resorted to heavy static analysis, and a bunch of hacks to prove nobody else is actually writing to that memory.

These hacks were brittle, leading to buggy or slow code, which is why C introduced the __restrict__ keyword, that allowed the programmer to tell the compiler that nobody is going to write to said variable, which meant it was now the programmer's responsibility to enforce that. High-perf code is littered with it.

I thought Rust's ownership system prevented mutable aliases, thus it allowed the compiler to automatically tag every pointer with __restrict__ , but if what the article says is right, Rust is bad as C/C++, because there are 1% exceptions to the general rule the compiler enforces.

I was reading summaries online 25 years ago as well.

Hell, in Italy we used to have an editor called Bignami make summaries of every school topic.

In any case, I don't know what to think about all of this.

School is for learning, if you skip the hard part you not gonna learn, your lost.

The more I look at that... Isn't that basically just a four-way yield, and the markings are mostly superfluous? You're basically doing the same motions in a regular intersection.

I guess that's the point, and the markings are just to give drivers the intuition of treating it like a regular roundabout (yield to your left [or right in the picture]).

Yep — what I had in mind was Orben & Przybylski, Nature Human Behaviour (2019). They use a specification curve analysis across three large datasets (total n ≈ 355k) and find the association between digital technology use and adolescent well-being is negative but very small (explains ≤ 0.4% of the variance). DOI: 10.1038/s41562-018-0506-1.

I think your cited meta-analysis (Liu et al., IJERPH 2022; DOI: 10.3390/ijerph19095164) is useful too — but it’s answering a narrower question (depression specifically, “time spent on social media” specifically) and it’s based on 5 studies with high heterogeneity, mostly observational/self-report. The paper itself basically says “interpret with caution; motivation/content/engagement matter.” So I don’t read these as contradictory so much as “big-average effect looks small, but there may be real effects for specific outcomes / subgroups / behaviors.”

Also worth noting newer longitudinal work is starting to tease directionality: e.g. Nagata et al., JAMA Network Open (2025) (ABCD cohort) finds higher social media use predicts later depressive symptoms more than the reverse. That to me is the strongest argument that “time” isn’t purely a proxy for pre-existing depression.

On “social media lumps together”: agreed research often names Facebook / Instagram / TikTok etc — but even within one platform, the mechanism differs a ton (DMs / group chat / creating vs passive feed consumption + ads + notifications). That’s why I’m more bullish on regulating business model + engagement features than banning the category.

And on “upward social comparison”: totally agree it’s not “solved” by chronological feeds. People curate; viewers compare. There’s direct work on the “everyone else is happier” perception effect on Facebook (Chou & Edge 2012, DOI: 10.1089/cyber.2011.0324) and adolescent social-comparison/feedback-seeking being linked with depressive symptoms (Nesi & Prinstein 2015). My claim is just that algorithmic ranking + push/autoplay/infinite scroll likely makes that dynamic more frequent/intense, so design changes still buy meaningful leverage even if they don’t make the risk zero.

I don't see things the way you do.

You look at gaining recognition for good ideas as a zero sum game that requires self promotion.

If you develop a good original idea that solves a problem and it gets implemented, you have created positive impact without self promotion. If you're not concerned with public perception, then the discussion stops right here.

Someone can take credit for your idea to gain perception that it was their original idea. But in the end, someone who self promotes that can't come up with original ideas will eventually lose their believability factor and will be unable to promote themselves much further.

First of all, if you have a mesh you don't have to connect to home server to talk to other devices in the same network. They connect to each other.

Second it's super easy to add a new device. Managing wireguard keys is annoying.

Third I don't have to open the port, worry about ddns etc.

Finally, for me it allows me to manage my DNS easily and I can leave tailscale running at all times. Also good luck implementing ACL on your own.

I don't see an issue with them logging when I connect to my stuff. The convenience for me is worth it more than the risk.
by xyst | 2026-02-01 16:31:27+00:00
I immediately looked at this and thought it was a tailscale clone.

I looked further into it and it’s essentially the same.

Implementation over ease of use of wireguard setup. Peer to peer modeling. Mesh networking. "Zero trust".

However, what I find interesting is netbird has open sourced their _coordinator server_. This allows for self hosting to be end to end.

yes with tailscale there exists "headscale", but it’s clearly a side project that few people within the tailscale company maintain on spare time.

One of the fears i have with headscale is a sudden change in leadership at tailscale, then the support from tailscale dies. Significant divergence occurs between headscale coordinator server and clients. Enshittification occurs and now forcing those smaller use cases onto their SaaS.

I love tailscale/headscale but will definitely give this a try.

My kids are in elementary school in the SF area (although pretty far in the ‘burbs) and this is not my experience.

The older one has a chromebook and uses it for research and production of larger written projects and presents—the kind of things you’d expect. The younger one doesn’t have any school-supplied device yet.

Both kids have math exercises, language worksheets, short writing exercises, etc., all done on paper. This is the majority of homework.

I’m fine with this system. I wish they’d spend a little more time teaching computer basics (I did a lot of touch typing exercises in the 90’s; my older one doesn’t seem to have those kind of lessons). But in general, there’s not too much homework, there’s good emphasis on reading, and I appreciate that the older one is learning how to plan, research, and create projects using the tool he’ll use to do so in future schooling.

Built this github app over the weekend.
The idea is simple: maintainers can require a small refundable deposit before accepting PRs.
The deposit amount depends on the contributor's reputation score. Trusted contributors pay nothing.

For legit PRs they get their money back, for low effort/spam PRs = maintainer keeps it.

Figured it might help with the PR spam problem some projects deal with.
No idea if anyone would actually use it but wanted to see what people think.

> The problems I've run into is both people giving fake citations (the citations don't actually justify the claim that's being made in the article), and people giving real citations, but if you dig into the source you realize it's coming from a crank.

Citations have become heavily weaponized across a lot of spaces on the internet. There was a period of time where we all learned that citations were correlated with higher quality arguments and Wikipedia’s [Citation Needed] even became a meme.

But the quacks and the agenda pushers realized that during casual internet browsing readers won’t actually read, let alone scrutinize the citation links, so it didn’t matter what you linked to. As long as the domain and title looked relevant it would be assumed correct. Anyone who did read the links might take so much time that the comment section would be saturated with competing comments by the time someone can respond with a real critique.

This has become a real problem on HN, too. Often when I see a comment with a dozen footnoted citations from PubMed they’re either misunderstandings what the study says or some times they even say the opposite of what the commenter claims.

The strategy is to just quickly search PubMed or other sources for keywords and then copy those into the post with the HN footnote citation format, knowing that most people won’t read or question it.

From what I can take from your reply I suspect you might not understand what attestation is for.

Yes you can use a chip that the bank trusts (that's your card), however the bank wants to trust that the hardware you use to read that chip is not compromised and does not try to do things on the behalf of the user that the user didn't authorize. A non trusted device can operate in a different way than the user demands of it, and the user might never know.

That's the use case that hardware attestation can prevent. Or so the theory says...

Recycling jewelry to make more jewelry is quite common, which kind of distorts how much the gold supply vs reserve is. If demand to manufacture jewelry ends then the supply of recycled jewelry also dries up.

~3,300 tons where mined in 2024

“Industrial and tech demand accounted for 83 tons of gold in the third quarter” of 2024. 83 * 4 = 332 so ~10% which is fairly typical.

While it has no bearing on the active case itself, within this thread it has bearing on exposing the political prejudice of the commenter influencing their opinion about the case. Would they have a different opinion if the variables were tweaked a bit, but the action and violation of the statute was the same?

It’s always a good exercise to evaluate your opinion this way, it should help keep you honest about legal fairness.

Information about received power and SNR is relayed over the 5G data link to and from the tower, and beamforming happens that way. As a result, the tower doesn't need to know where you are at all. In fact, with higher frequencies, you often get weird bouncy paths for 5G radio signals so the "beam" that gets formed can be a rather odd shape while being optimal.

We just had our first set of in person quizzes and I gave them one question per page, with lots of space for answers.

I'm concerned about handwriting, which is a lost skill, and how hard that will be on the TAs who are grading the exams. I have stressed to students that they should write larger, slower and more carefully than normal. I have also given them examples of good answers: terse and to the point, using bulleted lists effectively, what good pseudo-code looks like, etc.

It is an experiment in progress: I have rediscovered the joys of printing & the logistics moving large amounts of paper again. The printer decided half way through one run to start folding papers slightly at the corner, which screwed up stapling.

I suppose this is why we are paid the big bucks.

Like I said, I can't tell who is attacking who. Archive.is has more money, resources and ASN's than Akamai so surely they can mitigate anything anyone can throw at them. A little forum trying to respond in kind can't really be much of a threat. Archive could just tell their controlling nodes to ignore any requests to mirror the forum which means there is a lot more to this than any of us are seeing. That is why I would like to see the admin of Archive respond for both sides of the story.

> TYCO Print is a printing service where professors can upload course files for TYCO to print out for students as they order. Shorter packets can cost around $20, while longer packets can cost upwards of $150 when ordered with the cheapest binding option.

This made sense a couple of decades ago. Today, it's just bizarre to be spending $150 on a phonebook-sized packet of reading materials. So much paper and toner.

This is what iPads and Kindles are for.
