The article suggests that the people in charge of the system want children to be more involved in making political decisions. This signals a lot about what is happening in elite circles.

If that is the nature of the atmosphere then I doubt many important people are going to put their head above the parapet and call for reforms in the direction of adults getting better political expression. The power holders don't think that is favourable to them.

The underlying cause can be applied in other contexts. There was recently a flow where this vulnerability was exploited through an IDE working on customer tickets.

Don't dismiss the root cause because the usecase is silly. The moment some user provided input reaches an LLM context, all bets are off. If you're running any local tools that provide shell access, then it's RCE, if you're running a browser / fetch tool that's data exfil, and so on.

The root cause is that LLMs receive both commands and data on the same shared channel. Until (if) this gets fixed, we're gonna see lots and lots of similar attacks.

If adults thought completely rationally they wouldn't vote at all, since the chance of their single vote making any difference is insignificant.

Or even if they did, the amount of effort they'd put in researching, considering and modelling the potential outcomes would would be commensurate to the impact they would expect their vote to have. I suspect for a good chunk of adult voters, this is in fact the case.

So it's not obvious to me that including more voters whose decision-making is more emotional will necessarily produce worse outcomes. It's conceivable it'll produce better outcomes.

Edit: I'm being downvoted. To be clear, I'm an ardent democrat, but the idea that people vote analytically and rationally doesn't make sense for the above reason. The most informed voters are, in my experience, often highly emotional.

I think you can do throwaway projects and prototypes about as fast in rust.

But it requires a different mindset which I think many in our industry finds hard to work with. Rust exposes the imperfections rather than hiding them until you explicitly check for them like in most other languages.

Just clone and unwrap liberally and throwaway projects go fast.

Have you seen an "official" MCP directly provided by an email service yet?

I had assumed they weren't doing this precisely because of the enormous risk - if you have the ability to both read and send email you have all three legs of the lethal trifecta in one MCP!

So far, I have only seen unofficial MCPs for things like Gmail that work using their existing APIs.

I'm skeptical of the plan to provide a "kit" that can be put on arbitrary construction vehicles. I think Cruise tried something similar with personal vehicles and quickly learned it really could only build a system for a specific vehicle. There are tons of complexities associated with mounting of sensors and interfacing with the vehicle specific control systems.

Not saying it can't be done, but I wouldn't be surprised if the company has to pivot to supporting a subset of their goal and then gets bought out by some larger company to work on their line of construction vehicles.

Symbian was as far as I know the last mass market open phone platform for developers.

You had Qt, JavaME and a lot of others framework to develop your apps. The old Skype was working perfectly on those devices, with full integration.

Then Google tricked us into Android because it was Linux and open source, Apple said no more Java the future is the web.

And now my bloated bank app developed in React Native or whatever won't start on Lineage and Graphene because of Play Integrity API. Also I can't access my homebanking in my web browser. Strangely I also can't find anything as good as the old Skype with the same features.

I am not saying I saw the trap at the time and Nokia and Sun might have turned evil too.

I learned about this a few years ago and was delighted to hear some actual performances by Debussy of his own pieces. I was unimpressed by the quality of the recordings, though (via replaying on a restored mechanism) so it's great to get a MIDI version now!

How did the Welte-Mignon actually work? It seems almost miraculous that the dynamics can be captured on a piano roll and replayed successfully. Not perfectly, as you say, but pretty damn close.

> "In fact, recent research has found that adult and teen brains work differently. Adults think with the prefrontal cortex, the brain’s rational part. This is the part of the brain that responds to situations with good judgment and an awareness of long-term consequences. Teens process information with the amygdala. This is the emotional part."

This is a ridiculous claim. If you believe children think at all, they do it with the prefrontal cortex, just like every other mammal.
Show HN: I built a proxy to bypass adblock for OneSignal and Google Tag Manager
by egorzudin | 2025-07-17 11:21:58+00:00
Adblockers often block scripts like OneSignal (cdn.onesignal.com) and Google Tag Manager (googletagmanager.com), breaking push notifications and analytics on many websites. I needed a simple solution to restore functionality without requiring deep client-side changes or defeating user privacy.

So I built an open-source proxy you can self-host, deploy to Cloudflare Workers, and point your site to. It supports OneSignal and can be extended for GTM and others.

GitHub: https://github.com/verificatorrus/onesignal-proxy

Use cases:

Websites relying on push notifications or GTM metrics that get broken by uBlock Landing pages needing basic analytics and events with fallback SSR-friendly, no React/Vue required

Looking for feedback and suggestions! Should I add support for more blocked services (e.g., Meta Pixel, GA4, Mixpanel)?

The article does include at least one opinion opposed to lowering the voting age:

> However, Conservative shadow minister Paul Holmes said the government's position was "hopelessly confused".

> "Why does this government think a 16-year-old can vote but not be allowed to buy a lottery ticket, an alcoholic drink, marry, or go to war, or even stand in the elections they're voting in?" he asked in the Commons.

The lack of maturity also needs to be stacked up against the stake youth has in the future. Why should a 90-year old with little stake in the future be allowed to vote while young people who will live for another 70 years be at the mercy of that 90-year old's voting?

I think there is a good argument to be made that young people are the biggest stakeholders in our future, and should have a say.

This was relatively recently floated (2011) and thrown out to referendum (https://en.m.wikipedia.org/wiki/2011_United_Kingdom_Alternat...), where it was watered down to Alternative Vote rather than full PR and eventually rejected. Obviously none of these 16 year olds would have been old enough to vote in the referendum (or indeed have been born when it took place).

~One thing to bear in mind is that FPTP limits the influence of “extreme” parties on elections (see UKIP’s vote share in 2015), but at the expense of requiring more mainstream parties to pander to those voters to avoid splitting the vote share. Jury is still out I think on what’s “best” here and probably depends on what “best” means to the person forming an opinion.~

Edit: turns out the above is at best contested, at worst disproven.

SilentArena is a sandbox-style educational tool designed to simulate basic file-encrypting malware behavior — but in a completely safe and reversible way.

It operates only inside a `victim_data/` folder, uses XOR encryption, creates logs, and includes a scanner and optional decryption.

You're conflating acknowledging inefficiency with advocating for totalitarian control. I pointed out that meat production is wasteful that's just a fact. Your response is to claim I must therefore support banning computers and children?!

That's not how optimization works. We can improve systems without descending into authoritarian micromanagement. By your logic, we should never fix anything because someone might take it too far.

That just gives power to whoever administers the civics exams - which would obviously be a government controlled body.

Better idea should just be that you should be a taxpayer to vote. No tax = no vote. Why should people who aren't contributing decide how to spend the money of those contributing?

Correct, but they're not profitable, rely on quickly depreciating capital assets and loads of tech employees to maintain their services, so it's hard for me to believe that there's a sustainable business here for them.

And like, if anyone's gonna win it should be Google because of their ability to push capital into this for a long time, their world class infrastructure and their cost advantage by having their chips in house. But I have faith in their ability to snatch defeat from the jaws of victory.

It doesn't matter who we vote for, as long as we vote? What a bad joke. By this theory, all foreign interference, propaganda, education, control of the news, etc.. are completely irrelevant, nothing we should be concerned about at all. Just vote and it'll be fine!

> You don’t always need a vulnerable app to pull off a successful exploit. Sometimes all it takes is a well-crafted email, an LLM agent, and a few “innocent” plugins.

The problem is that people can say "LLM agent" without realizing that calling this a "vulnerable app" is not only true but a massive understatement.

>If someone only has one phone as their personal computer for everything then I can see an argument that the minimum should be higher

Yeah for those people, they would need a beefier phone. That's certainly not me, I have devices at home. In my case, a pure dumb phone isn't of much use to me either, I make maybe one or two phone calls most months, but I've always used my phone as more of a borderline feature phone.

>a full PC or larger phone/tablet for ticketmaster.

The problem with ticketmaster is that you need to use it at the events themselves. Most events no longer use physical tickets. But a stronger phone or tablet won't help you here. Even on a high-end phone, ticketmaster will somehow forget to store your login information while you have poor network connectivity due to tons of people in the area, even if you try to load your tickets ahead of time to avoid the issue (although somehow they always deliver ads!). Everyone complains about ticketmaster's fees, but the app is the worst part.

(can't edit anymore)

I should have read the entire article first - of course we are in protected mode, and with no exception handlers defined in the IDT it would triple fault. I stand by my comment about FFFFh, this isn't a NOP on older or newer CPUs, so almost certainly not on the Pentium III either.

As to what happens on 4G wraparound, I could only find this in the Intel manual (SDM Vol. III, 5.3 Limit checking):

>When the effective limit is FFFFFFFFH (4 GBytes), these accesses [beyond the segment limit] may or may not cause the indicated exceptions. Behavior is implementation-specific and may vary from one execution to another.

Metaflow was started to address the needs of ML/AI projects whereas Airflow and Dagster started in data engineering.

Consequently, a major part of Metaflow focuses on facilitating easy and efficient access to (large scale) compute - including dependency management - and local experimentation, which is out of scope for Airflow and Dagster.

Metaflow has basic support for dbt and companies use it increasingly to power data engineering as AI is eating the world, but if you just need an orchestrator for ETL pipelines, Dagster is a great choice

If you are curious to hear how companies navigate the question of Airflow vs Metaflow, see e.g this recent talk by Flexport https://youtu.be/e92eXfvaxU0

If adults were rational they'd use their communication skills to form broad coalitions to make sure that policies they like get put in place. Which is largely what happens.

> Or even if they did, the amount of effort they'd put in...

This is actually quite an interesting area if you look into the game theory of making choices in a group setting. Strong strategies typically often don't involve doing much research, but they are rather frustrating for the people who take an interest in politics. Real-world behaviours are arguably quite reasonable on this front too, although they are limited by the ability of the average person to reason their way through the policy suggestions being made by though leaders.

Although I do agree that more voters isn't better. There is a certain level of objective correctness in political decisions if we admit basic ideas like "policies should be tested to see whether they achieve the goals that they were intended to" as a measure of success and the point should be to design systems that optimise on it to some degree.

Yeah - but mainstream economics is far more a state religion than it is just-a-religion. The priesthood is superficially concerned with the welfare of the masses, theological consistency, etc. - but the actual priority is divining what words, doctrines, and predictions would best serve the interests of the wealthy and powerful, and regularly pronouncing those. And vehemently denouncing any heretics who get too interested in the actual welfare of the masses, or the track record of the priesthood's predictions, or other dirty truths.

So long as you have the right mindset, being a priest of a generously supported state religion is a very cushy job.

It’s an interesting middle ground between technology, psychology and art. As I said in the article when I compared the skill set with that of the architect. Personally, I find that one of the most interesting aspects is the “usability” of typefaces. What is usually called legibility. But if you think about it, it’s really the usability of a typeface. I wrote about that too (and will again): www.nubero.ch/blog/011/

Assembler is much better approach, one gets to learn how the machines actually work (ignoring the microcoded part), and reach for something like a 8/16 bit computer emulator (ZX, C64, NES), or an Arduino like device with ARM/RISC-V.

Also the realization, C isn't that special, plenty of ways to play around with pointers.

Possibly used for knitting?

How parochial. My oldest brother came back with a block with a hole cut in it, with 4 nails, wanting to buy yarn. Soon me, and my two brothers were using all of our nervous energy cranking out red, blue and rainbow colored finger tubes by the dozen. We gave them to someone who knew how to crochet, and were given plastic blocks to knit the hands, each in our size, in a months time, we each had three pairs of warm gloves for the mornings. We gave the blocks to our younger cousins in Canada, and they cranked out enough gloves for classrooms of children.

So when I saw these devices, I knew exactly what they were for: 1. Making gloves. 2. Confusing people who never had used a knitting block, and 3. causing un-due speculation.

Why no wear on the nob necks? Soft wool. Our blocks used high carbon steel finishing nails, which never wore, but even brass, would at first polish, and then would patina over, leaving no marks.

Why no hooks? for finishing? Those would have been made of wood, and like other looms, would have disappeared. what they should be looking for is collections of brass nails.

I really hate when these ideas come of that effectively boil down to creating some kind of litmus test for who can be "trusted" to vote. We have an age limit, maybe the UK wants a lower limit, but at least that's a pretty simple and clear line to be drawn.

RTGs (radioisotope thermoelectric generator) are already in use for both deeps space and remote applications. Not sure how this differ. Maybe better efficiency? Still, why is it called a battery instead of a generator?

Oh, maybe size as RTGs are bulky.

edit: there have been very small RTGs for use in pacemakers. The difference is really that these are not thermal but use the beta flux directly.
Show HN: I built an interactive tool to beat my study
by Bslou | 2025-07-17 11:29:18+00:00
Hey HN,

I’m Ben, a UCLA student who’s way too familiar with “just one more video” or “one more game” derailing a study session. After far too many hours squashed into my gaming chair instead of hitting the books, I decided to do something about it. Enter Octivus - my attempt to turn studying into something as addictive as a game.

I started building this for myself, but after a couple of failed launches, I asked my friends at other colleges and realized we all share similar procrastination problems. Their stories gave me ideas for making Octivus more addicting (by including addictive backgrounds, study games - like endless runner video game, matching game, flashcards, etc.), and productivity hacks (like a calendar in underwater theme).

If you’re juggling assignments, exams, or just trying to keep your focus alive, give Octivus a spin. If you love it, I'm glad, and if you hate it, please let me know your feedback. I’m all ears and ready to make this thing better.

Thanks for checking it out, and here’s to fewer distractions (and more A’s)!

The US will likely go down the same path every other country has gone before with an unpayable debt burden: Just inflate it away. Which is bad for people with fixed-income investments in the US and across the globe, ie. mostly pensioners and people with lots of bonds in their retirement funds. And also likely bad for people with jobs who will face yet another cost of living crisis. If your money is in real estate, equities or gold you should be fine though.

Depending on how degraded the original battery was it isn't necessarily placebo. If iOS detects a severely degraded battery it will clock down the CPU slightly to cope with it, sacrificing a little performance to keep the device stable.

With 3rd party batteries it can't do this, so it doesn't (I think, will admit I'm not entirely sure exactly how iOS deals with 3rd party batteries it can't determine the status of), and if you replaced it with an official part then it would have been in good condition, so regardless which road you took, it's possible that you went from a state where the OS was clocking down, to one where it wasn't anymore.

> Surely chicken in your backyard can be kept without CO2 impacts with some effort.

I’m not sure this is possible, at least not in a typical yard or urban garden. According to one study[1] community gardens in and around cities emit six times the CO2 per serving compared to industrial agriculture. I assume this is roughly applicable to backyard gardens too. I wouldn’t be surprised if this isn’t applicable to livestock—which the study appears to have excluded—but also wouldn’t be surprised if the story is similar with chickens/livestock.

I imagine that even if it is less efficient to grow your chickens in the back yard, it might be possible to approach or exceed current industrial poultry farms in CO2 efficiency. My hunch is that if those farms get incentivized by penalties on CO2 production it would be impossible though.

I'd be interested in a system where you can gain additional voting power based on $stake. Everyone gets a vote, but based on $criteria, you gain additional votes.

Youth and parents get an extra vote on school stuff. Those whose education or career are related to a field get an extra vote. In some cases, you may hold 5x the voting power of someone who is removed and unfamiliar with a topic.

No idea if anything like that has been explored.
