Dynamicland is bootstrapped in a sense, [0] the same way you write the first compiler/interpreter for your code in another language then later write it in it's own language. The code running the camera and projector systems is also running from physically printed programs in one of the videos you can see a wall that's the core 'OS' so to speak of Dynamicland.

I think the vision is neat but hampered by the projector tech and the cost of setting up a version of your own, since it's so physically tied and Bret is (imo stubbornly) dedicated to the concept there's not a community building on this outside the local area that can make it to DL in person. It'd be neat to have a version for VR for example and maybe some day AR becomes ubiquitous enough to make it work anywhere.

[0] Annoyingly it's not open sourced so you can't really build your own version easily or examine it. There have been a few attempts at making similar systems but they haven't lasted as long or been as successful as Bret's Dynamicland.

> A quarter of the participants saw increased performance, 3/4 saw reduced performance.

The study used 246 tasks across 16 developers, for an average of 15 tasks per developer. Divide that further in half because tasks were assigned as AI or not-AI assisted, and the sample size per developer is still relatively small. Someone would have to take the time to review the statistics, but I don’t think this is a case where you can start inferring that the developers who benefited from AI were just better at using AI tools than those who were not.

I do agree that it would be interesting to repeat a similar test on developers who have more AI tool assistance, but then there is a potential confounding effect that AI-enthusiastic developers could actually lose some of their practice in writing code without the tools.

> Young people have little fear of repercussion as they cant really fathom the consequences.

> But it is very well understood and accepted that teenage - especially male prefrontal cortexes don't fully develop until mid 20s.

Your statement here does not mean that the statement I quoted above is true. Just because biology predisposes one to doing stupid shit does not mean young people are incapable of understanding consequences and repercussions. The fact that most of us here never went out to cause millions of pounds of damage is testament to that.
Show HN: Pwettify – dead simple universal CLI prettifier
by cookiengineer | 2025-07-10 21:05:49+00:00
Today I got really annoyed at existing prettifier tools that I was using to reverse engineer a binary, so I built a little CLI tool that just prettifies files based on their file extension and/or headers, and which doesn't need runtime dependencies when installed as it's a standalone go binary. I wanted it to be as simple as possible, without any overengineered CLI flags that nobody will be able to remember.

Maybe this tool will be helpful to someone else, too.

~Cheers

I meant useful in general. It's slightly off topic, but I think many people overlook the fact they are just a bluetooth mesh network as well.

Imagine one just as large as the airtag + iphone ecosystem but with messaging capabilities!

Would be cool to see one built into android + iphones but that will never happen. But a 3rd party could get so popular that it achieves somewhat close to that.

I'd imagine remote villages and towns could all install this and communicate with each community member very effectively.

What i am making up? That US healthcare has high margins?

“ study from Yale School of Medicine (YSM) found that large U.S. health care corporations spent 95% of their net income — totaling $2.6 trillion — on shareholder payouts over the past two decades, raising questions about industry priorities and their impact on patient care and affordability”
by jakeydus | 2025-07-10 21:06:38+00:00
On the one hand, congratulations on building something, OP.

On the other, this kind of tool is going to be the death of online networking/social media. I already was able to barely stand LinkedIn, but since every influencer on the platform started using AI to write their content for them, there's even less worth consuming. I quit watching YouTube shorts for the same reason. The advent of AI-powered content generation has only served to drive me away from the places that content exists.

We are in a community of hackers. There are tools such as VPNs which are effective at bypassing these requirements. That will likely change in a few years as the government will want to crack down on circumvention techniqus. The law is incidious enough to actually suggested that educating people on how to bypass the checks is not allowed - I sincerely hope no court ever upholds that otherwise the very act of education is at threat.

So the end result is using tools such as VPNs or fake videos to bypass the system. Or creating new communities which do not have such restrictions (but they won't be able to be big platforms anymore as they will fall into scope).

So you could have 1000's of smaller bulletin boards. Once they get large enough they'd need to shut down and restart in order to not be within scope.

Alternatively there could be some legal challenges on the way to define the scope of their powers (so far there's not been any enforcement conclusions to challenge, although there are some investigations by OFCOM ongoing)

I think the gray area is that the student is not in the US. They are in another country, and are applying at a consulate/embassy.

Many of the rights US residents have don't apply to visa applicants.

In any case, there are plenty of examples in the past where the US denied people entry based on stuff they've publicly said/written. What's different here is requiring you to disclose all your handles and make them public.

Sounds good, but doesn’t work. I still have bills to pay and a family to feed. If the cost of saying no is that I lose my job or get put in the doghouse without a promotion because a person with more influence got upset, I will put up with it and do whatever is asked of me. I may leave the company later if I find another job and they might also find another person to replace me, but that project is moving forward one way or the other.

Again, if I’m being asked to risk people’s lives, I’d push back harder and resign if I can’t change minds, but I’m not doing any of that to “elevate our profession”.

Of course, lot's of hype, but my point is that the reason why is very different and it matters: As an early bc adopter making your believe in bc is super important to my net worth (and you not believing in bc makes me look like an idiot and lose a lot of money).

In contrast, what do I care if you believe in code generation AI? If you do, you are probably driving up pricing. I mean, I am sure that there are people that care very much, but there is little inherent value for me in you doing so, as long as the people who are building the AI are making enough profit to keep it running.

With regards to the VCs, well, how many VCs are there in the world? How many of the people who have something good to say about AI are likely VCs? I might be off by an order of magnitude, but even then it would really not be driving the discussion.
by scott_w | 2025-07-10 21:08:03+00:00
I’m a bit torn on that, honestly. Were this an embarrassing hack like the ones I read about as a teenager, I’d agree. However, they caused millions of pounds of damage to multiple companies (and their customers) and attempted to blackmail the CEO for profit.

I’d be amazed, and I think the public would be outraged, if they got a slap on the wrist for this.
by xg15 | 2025-07-10 21:08:16+00:00
Are you suggesting that the entire population of the UK switch to using VPNs?

> So you could have 1000's of smaller bulletin boards. Once they get large enough they'd need to shut down and restart in order to not be within scope.

This will work until the moment some actual pedos run some of those small message bords and use it to groom kids and politicians will have the necessary munition to shut down those sorts of exceptions to the law.

I'm routinely ridiculed for driving a car with a traditional ignition key, and insisting upon it, as if it's exclusive to Luddities.

Everyone else can enjoy their reflection/replay attacks or whatever.

Honorable mention to Toyota who has still not completely abandoned this simple, functional technology for a clunky fob that can be easily hacked.

FWIW, fobs are not for your convenience. It's for theirs.

That's similar to the issue with the whole NFT craze where you'd "take items from one game to another", it requires everything to work with everything.

For Dynamicland I get the issue though putting the whole thing through an LLM to make pointy and sharp both trigger the same effects on another card would just hide the interaction entirely. It could or couldn't work for reasons completely opaque to both designer and user.

Hey guys why are we making it so complicated? do we really need a paper and study?

anyway -AI as the tech currently stand is a new skill to use and takes us humans time to learn, but once we do well, its becomes force multiplier

There has been no reaping. MKS shares were largely unimpacted (despite this costing at least £300m). Management have tried to deflect, said this was a highly sophisticated attack, said that other firms had been hacked but just didn't report it, endless amounts of lying.

The reality is that decreasing costs is a far easier lever to pull than increasing revenue so managers will be heavily incentivised to do this if you give them profit-based incentives. This happens every few years with listed companies in the UK now, no-one ever changes their behaviour (retail, in particular, is ground zero for bluffers in the UK, managers are exceptionally bad, and even worse are comp committees that set targets that cannot be achieved without damaging long-term value).

There is no efficient market here. It is as simple as managers understanding the world we now live in, and that is unlikely because all these companies view IT as a cost and their managers are people who rotate through executive roles and politics despite leaving a flaming wreck in their wake. Things will stay the same.

For standard email, fastmail.com is very very good. Plus they're working on JMAP, which may actually improve standard email for everyone.

If you're okay with a non-standard email account that you need to use their app for, hey.com has been a game changer for me. Being able to handle the flood of incoming messages that comes from having an email address for 35 years.

> I would put a lot of money on it not being able to detect you pointing your phone at a Veo3 video of an old person though.

I recently had to verify my identity for UK government company registration purposes.

I had to use my phone to scan my biometric passport, then it did facial recognition while flashing the screen between red, green and blue. Presumably doing... something... hoping to detect fake faces.

(as well as the biometric passport and modern phone, it also needed an e-mail address, password, TOTP code, verifying the e-mail address, full name and address, and year I moved into the address, and I had to log in about 5 times...)
by bravoetch | 2025-07-10 21:10:51+00:00
For the average person, probably not much use. But we're in an interesting time where laptops and phones are ubiquitous and all of them have bluetooth. It being open source, and already ported to Android, is a bit special too. Seems like a coinflip whether it catches on, and if people start using it for concerts, festivals, group camps or whatever, then in a disaster it will already be there for people.

Those are not the same at all.

Search for "swept path analysis" for just one component of what you're missing. (There are many other components of design of a curve like this to consider.)

A 90 degree change in direction is fine by itself provided there is sufficient radius for vehicles to make the turn at the design speed.

In this case, if its two lane you may not be so convinced of its safety when it's your loved one on a scooter who got hit by a bus which tracked over into the oncoming lane just to navigate the curve. Or if its a single lane, when they died on the ambulance which was stuck in traffic on the bridge because two vehicles are unable to pass and everyone behind them would need to backup in unison to sort out the resulting cluster.

But safety is only part of the duty to the public here. The bridge needs to function for its intended specification and if it fails to do so for basic engineering reasons, you absolutely have no business holding a license and signing off on public plans and indeed you would be disciplined or stripped of your license for something like this.

UK Voters or no one, depending on which half of the glass you focus on.

Sovereign power is scary af, but in theory also kept in check by voters. The problem is that no matter what form of government you have, it is still downstream from culture, and if this kind of policy is what UK voters want or can be talked into wanting, then this is what the King’s subjects shall get.

If you're going to keep them all locally anyway, what's the point of IMAP?

(Admittedly my judgement was formed at a time when one user, one device was the rule. I suppose if mobile access to email is important, there's a good argument for keeping the data server-side. I solve that problem with VNC.)

There is a fair amount of industry, but the buildup of wind power is relatively new. Lots of new datacenters are being built as cheap renewables, abundance of water, and a cool climate create a great environment for them.

Finland has lofty goals for becoming a hub for new green energy intensive industries, but these require large amounts of capital and it'll remain to be seen if that realizes.
by brookst | 2025-07-10 21:13:11+00:00
No, the vector is in a semantic embedding space. That's the magic.

So "the sky is blue" converts to the tokens [1820, 13180, 374, 6437]

And "le ciel est bleu" converts to the tokens [273, 12088, 301, 1826, 12704, 84]

Then the embeddings vectors created from these are very similar, despite the letters having very little in common.

I recently had to scrub my former employers S21 to send it back and evidently I have to say Samsung doesn't really do this anymore, at least not in the EU.

You are greeted with a screen with all the crap it wants to install after turning on the phone for the first time (which you can fully skip) and that's it. A One UI 7/8 setup can be pretty bare bones and minimalistic if you want, at least here in the EU.

Case in point: what's happening to trans kids in the UK at the moment.

If you don't think this technology will be used to keep kids from connecting with peers like themselves, or learning or reading about themselves, because of some trans panic, you haven't been paying attention.

Politicians all over the world have put forth legislation like this with the explicit purpose of preventing LGBT kids from connecting with peers or learning anything related to their identities[1]:

> A co-sponsor of a bipartisan bill intended to protect children from the dangers of social media and other online content appeared to suggest in March that the measure could be used to steer kids away from seeing transgender content online.

> In a video recently published by the conservative group Family Policy Alliance, Sen. Marsha Blackburn, R-Tenn., said “protecting minor children from the transgender in this culture” should be among the top priorities of conservative lawmakers.

Ah, but here's the kicker - we are a small school. My graduating class had 140, and it's shrunk since then. I believe the grades are now about 110-120 each or so. However, we have some very successful sports programs. The girl's basketball team has won state countless times, for instance. Either way, there are only so many spots on a team and if almost everyone is doing travel teams you don't have much of a chance if you don't.

I would say that while Google's MediaPipe can technically run any tflite model, it turned out to be a lot more difficult to do in practice with third-party models compared to the "officially supported" models like Gemma-3n. I was trying to set up a VLM inference pipeline using a SmolVLM model. Even after converting it to a tfilte-compatible binary, I struggled to get it working and then once it did work, it was super slow and was obviously missing some hardware acceleration.

I have not looked at OP's work yet, but if it makes the task easier, I would opt for that instead of Google's "MediaPipe" API.

Well, with 6.5 GW for 2.5M households, you’re at a peak around 2.6kW per home.

Assuming these turbines are always at nameplate production, which they are not, they produce 6MW. Spread among 7k homes, that’s less than 1kW, which is not a lot.

Given the previously stated peak of 2.6kW per household, 6MW would cover about 2300 homes.

The only way you could get to this kind of number would be if you calculate the average use for a household over a year. But then you would have to compare it to the plant’s yearly production rather than its nameplate capacity.

Wikipedia quotes MeyGen at 10.2GWh in 2023, that means 1.14MW on average instead of 6MW. Assuming perfect storage, that would mean an average of 163W per house for 7000 houses. That is barely enough for a fridge.

> Also I would say the expression "powering a home" usually implies average demand not peak demand.

That's my issue. Comparing average demand to nameplate capacity is dishonest.

I had moderate success using https://www.iso.org/ISO-house-style.html converted to markdown and narrowed to the guidelines starting with "Plain English" and ending before "Conformity and conformity-related terms" (plus a few other rules up to and including "Dates"). A quick estimate puts the whole Markdown document at 9869 tokens - quite manageable. I generally prefer the style of the Microsoft Writing Style Guide but ISO house style is the only one that fits nicely into a prompt.

Looking forward to your model/product!

Nope. I'm talking about regular, R1 schools.

Source: Local state university in an interview. This came up during the issue of affirmative action. They pointed out (with actual statistics) on how most of them have open admission. The context was that admitting someone via affirmative action was not depriving anyone of a seat.

This was for "regular" undergrad admission. Grad school/business/law/medicine (perhaps pre-med) may be different.

Ah, you do you. It's just a fairly kindergarten thing to point out and not something I was actively trying to hide. Whatever it was.

Generally, I do a couple of edits for clarity after posting and reading again. Sometimes that involves removing something that I feel could have been said better. If it does not work, I will just delete the comment. Whatever it was must not have been a super huge deal (to me).

Out of curiosity: Would appreciate if others can share what other things like AccessExclusiveLock should postgres users beware of?

What I already know

- Unique indexes slow inserts since db has to acquire a full table lock

- Case statements in Where break query planner/optimizer and require full table scans

- Read only postgres functions should be marked as `STABLE PARALLEL SAFE`

interesting, i might end up doing something similar. if you don't mind me asking, how much did you sell the remainder of your shares for? was it close to your FMV? i feel like i'm already being negotiated hard by being forced to sell my equity to minimize dead equity and then instead of selling at the 409A valuation, being sold at the FMV seems like i'm losing another battle. thoughts?

Agreed, I am struggling to understand why "it does not scale" is not "we used it wrong and hit the point where it's a problem" here.

Like if it needs to be very consistent I would use an unlogged table (since we're worried about "scale" here) and then `FOR UPDATE SKIP LOCKED` like others have mentioned. Otherwise what exactly is notify doing that can't be done after the first transaction?

Edit: in-fact, how can they send an HTTP call for something and not be able to do a `NOTIFY` after as well?

One possible way I could understand what they wrote is that somewhere in their code, within the same transaction, there are notifies which conditionally trigger and it would be difficult to know which ones to notify again in another transaction after the fact. But they must know enough to make the HTTP call, so why not NOTIFY?
by aboringusername | 2025-07-10 21:18:12+00:00
Yes, because that's how the internet is designed to work, a VPN just routes packets to another location with the nice side effect of being able to use another IP address.

Countries have tried to enforce censorship but even places like China have gaps that are exploitable if you have the right tools and knowledge.

Everyone should be learning about how to bypass state overreach, it's an obligation of its people.

I feel like it probably has particilar applications, especially if seamlessly integrated, but I also can't but help feeling like there's a certain level of "protocol fatigue" for non-tech folks.

In my experience a lot of people dont really understand the distinction between WiFi and Cellular for example. Or maybe more relevant, SMS vs MMS vs RCS.

That's not to say it can't or won't work, but rather the tech is interesting but I imagine a lot of potential friction for early adopters, which seems (to my limited understanding) self defeating as it only works if there's a critical mass of users.

Thank you! This exact scenario happened to me today. I would have never noticed the footnote. It says "Includes everything in Pro". Seems totally insufficient at pointing out that Claude Code is not included.

* Edit: Just realized we can do usage based billing and you can create a team in there. It was difficult to figure all this out. I think we don't need a "Team" account any more. My guess is they're going to add Claude Code to the Team plan soon and they're just in-between those changes, making it confusing.
