I'm continuously building and improving https://lectronz.com/, a marketplace for electronic enthusiasts and professionals that focuses on the open-hardware and DIY electronics communities. We recently introduced "Threshold Pre-Orders," a pre-order mechanism that lets hardware creators gauge the market before committing to production/PCBA. We have successfully tested this on four low-volume products already. See https://lectronz.com/u/lectronz/articles/introducing-thresho...

You misunderstand. Your taxes are not for infrastructure. It's for a ships and planes, guns and ammo, and interest to pay our debt. It's to cripple our enemies and intimidate our allies. It's also to keep the masses of desperate people from starvation so they do not take to the streets, but you needn't worry about that soon.

You will sacrifice more for this system you see little benefit from. You may be called to fight for it, and you may even die for it, and the people who benefit the most from all of this killing and waste will eventually lose their hold on power due to the putrid state of the system itself.

I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.

It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.

The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).

More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.

If this sounds interesting, feel free to join our Discord! The project is still new and feedback is highly appreciated. http://asterai.io/discord

Maybe that's regional or specific to some chains, but not universal. About half the people in my gym come in only for cardio machines. The PTs start with - "so what do you want to achieve?". As for sports you listed, soccer and basketball rely on available groups - it's not for everyone; climbing depends on available walls which only exist in larger towns and cities (1.5h to my closest one); running/cycling depends on various conditions, so many people do that... at the gym.

Given only speedups any formula to combine them is meaningless, because the real question involves a concrete workload: would the performance of what I'm going to do with my computer improve enough to justify the cost of improving it?

At the very least, weights for each benchmark task are needed; complications of the cost model (beyond a binary old system/new system comparison) are also likely.

Measuring performance improvement by speedup of throughput is also often naive, since there are other dimensions (like power and latency) and complex requirements.

There was a CCC talk on the practices of the Stasi some years ago (I forget exactly which year).

What stayed with me from the talk was that they had shown recovered Stasi photos of a young man's home where he had a wall dedicated to American iconography.

The speaker stated that in the current era this would just be trivially collected from social media instead of needing to gain physical access to property.

Edit: It was 32C3 What Does Big Brother See While He Is Watching at appx the 40m mark.

Greed is an inherent evolutionary characteristic (non-greedy species had an unexpected appointment with extinction).

Social species may have charity within the in-group, but are still fundamentally greedy against the out-group.

Collaborative communities can only exist so long as all its members abide by the social agreement, and there's a scaling limit on how far you can maintain a consistent social agreement.
Show HN: We built an AI that learns and remembers your screenshots
by ghanhanhan | 2025-04-28 08:01:50+00:00
Hi HN, Gunhee and Harry here. We're excited to launch Shotup AI — an AI assistant that learns and remembers your screenshots.

Many of us take screenshots to save important info, but over time, our photo albums become chaotic, and it’s almost impossible to find the right information when we need it.

The AI understands the content and context of your shots. It lets you search by description, like "The modern interior design reference I saw on Instagram." It helps you recap, organize, and remind you about important saved info.

How it works:

1. Select and sync your screenshots from your photo album

2. Choose recommended custom questions based on your shots or ask Shotup AI anything via chat

3. Get weekly and monthly recap summaries to rediscover forgotten saves

We believe screenshots are the new bookmarks for mobile. If you have any questions or suggestions for features, please share. Would love your feedback.

I am going to go out on a limb here and I assume you are, in fact, human ( this is a rhetorical device and not accusation of poster being llm ). As such, you likely should know that life in general is inherently not fair. And if you are going to be bold and trot out society during this argument, we are going to have a lot of fun.

I was looking into advice on lifting weights not that long ago and this was very noticeable to me.

The stuff you find online didn't even allow for the possibility that there were other goals even as they discussed the risk of life changing injuries from certain practices.

It was just "will this grow muscle size more and faster" when I was looking for some science backed answers on what was the minimum time/money/risk way to be healthy and active in the long term.

One person who stuck out for going against this was an expert in back jnjuries asking older weightlifters "Do you want to keep setting personal bests or do you want to be able to play on the floor with your grandchildren as you can't do both"

Whenever I go to a tech conference, I see slide after slide filled with a wall of text, or in the best case 3 to 5 bullet points with text only.

A picture says more than a thousand words.

As much as I'd like to use a simple markdown based tool to create my presentations, most of these appear to come short regarding visuals (1).

Look at the 2007 iPhone introduction - thats how you use visuals to deliver a message.

Going from bullets to visuals is definitely not easy, and while I'm not as brilliant as Steve Jobs, I always give it my best shot. And a supporting tool makes it a lot easier.

(1) if anyone knows about a md-based slide creator supporting good visuals, I'm open to suggestions.

These days, the formal difference between the two is really hard to grasp, and mostly depends on which way accountants find they’ll pay less taxes.

There is no point nitpicking someone because they used one term instead of the other: Bezos’ fortune is derived from Amazon’s activity, and the rest of us has no interest in changing our vocabulary to abide by some obscure tax code rule.

It depends how you are defining "better". Much cheaper and safer sure, but also much slower and much more limited. If it was me making the decisions I'd still go with robots, but I wouldn't call them "better".

Apollo 17 astronauts drove roughly 12 miles in around 8 hours to get to a site and do some science. The curiosity rover's longest drive in a day is around 150 meters. If it drills a rock and encounters some difficulty, it has to wait send a reply home, wait another 4-24 minutes for the message to get there, wait 4-24 minutes for a message to come back before proceeding. It's also obviously unable to conduct repairs on itself or it's tools, or even do something as basic as cleaning the dust from itself.

Robots certainly have the advantage in longevity; curiosity has been operating since 2012 and is still going, but it's like comparing a roomba vs a team of professional cleaners. I think if you asked a planetary scientist if they'd could go back in time and instead of sending curiosity, send a couple of people for six months, they'd do it in a heartbeat.

> The difference is so noticeable, it is now called "two tier policing".

That’s what Elon Musk calls it. In fact, the difference in the case you mention is simply that:

(i) Inciting racial hatred is a specific offense which doesn’t require a credible death threat. There is no offense of inciting hatred against TERFs. Like that or don’t – but the police don’t make the laws.

(ii) The context of Connolly posting during the riots in which actual violent crimes against minority groups were being committed.

Do you know OP personally? Do you really think it's reasonable to assume that everyone in the universe (except for you, perhaps) is a hypocrite like this?

There's plenty of people that feel the administrative force of the university shouldn't be used to suppress either side. Let the gun club invite Luigi. Let the trans club invite the Stonewall rioters.

My feeling is that they're just built different, military, especially in US will either teach you or make you disciplined (not something I'd say about my country, you'll learn how to get hazed and drink). If you have a task, well, you better solve it quick, no distractions.

I've set up IIAB and tried Kiwix as well. I used a Pi Zero 2 and as it's only me using it, I found the user experience was good, although given the Zero's power, not high-speed. I managed to gain enough knowledge to create my own ZIM files of some selected YouTube content ( including my own). Being aware of the recent propensity of useful data to "vanish" I've approached a couple of online content providers to see if they'd ask to get their content added to Kiwix: sadly I heard nothing back, but I'll keep trying.

<< They want to import people who will benefit the nation state.

You might be getting a little ahead of yourself. Yes, the nation state does what serves its interest, but we are not discussing what the nation state wants. We are not even discussing what the populace through small d democracy wants ( as the two are automatically aligned ). We are discussing, who is a part of the group that can want.

That’s the problem. It’s up there. Getting it down requires you to get something of significant mass up there to provide that delta v to deorbit it, and even then you’re not entirely sure exactly where it will land. You could probably target a large country, but not a city.

Instead use all that feta v you need to get your “shoving device” and just send it direct.

To deorbit one of those satellites you need an icbm capability already

That's disturbing. Instead of the govt. going after people we should enable people going after people.

That's how it's done in real life and that's how we protect ourselves from arsholes in real life. That's why the police is only involved when some actual danger is present, you are not expected to just endure the constant harassment.

IMHO someone being a complete cunt and you not having a recourse is also not acceptable. It's terrorizing people, there must be a mechanism to stop these people and that mechanism should not be police intervention.

The things they do should somehow stick to their name for example or you should be able to go after them just as brutally. Honestly, I like 4Chans way with dealing with people much more than restricted, moderated police involved crap that the Web has become. Someone built a following, then they harass people but your only recourse is legal stuff and you can't do doxxing, can't use bad words etc because you get banned/demoted/shadowbanned/rate-limited. It's not working, it's destroying the society.

For example, the women jailed for just tweeting plead guilt that she was spreading materials with intention to stir racial hatred. In a real life such person will be quickly stopped one way or another, she will be confronted and then removed or ignored. If her material is actually good, it will be noted and supported and the issue resolved. Online is not like that people with agenda lie, spam and annoy people without facing a pushback or consequences. It's not a real discussion, it's not real problem solving.

I think we got the far right reality of today by liberals completely ignoring working class pain and appearing to solely focus on a controversial minority. I say appearing because they didn’t seem to do anything else.

This allowed the current administration to step in by promising something different, with no intention of delivering anything but tax relief for the wealthy and unchaining corporations from those pesky regulations that prevent higher profits.

> WiMAX never really worked well at all

Neither did LTE (or VoLTE) work well at the start.

WiMAX didn't get the funding and backing primarily because it didn't integrate well with existing systems. Hilariously it fit the criteria as 4G before LTE did. I guess there was a strong vendor push to include LTE into 4G.

Yeah but dropping advertising (or regulating it) does not necessarily imply a monopoly in terms of who provides what.

That what I wanted to understand. I understand the other way around, that a socialist panned economy with monopolies in terms of who produces what is shit. And leads to advertising not being necessary. But the other way round is what still trips me off and what I am still not able to wrap my head around.

No material is cheap when it has just been developed. Titanium alloys were science fiction in the 1980s, and now I can find titanium camping forks and mugs for €10.

Special steels can also cost a fortune (powder metallurgy, superduplex).

There are many more foundries and workshops producing copper alloys than nickel alloys. The supply chain is much simpler and more diverse.

Copper recycling is a reality, but nickel alloy recycling is less so. Significant efforts are being made to reduce dependence on rare metals. No one really knows which ones will actually break through in the future. But having more options is always a good thing.

I have tried playing chess with ChatGPT a couple of times recently, and I found it was making illegal moves after about 4 or 5 moves.

The first few could be resolved by asking it to check its moves. After a few more, I was having to explain that knights can jump and therefore can’t be blocked. It was also trying to move pieces that weren’t there, onto squares alert occupied by its own pieces, and asking it to review was not getting anywhere. 10-15 moves is very optimistic, unless it’s counting each move by either side, i.e., White moves 5-8 times and Black moves 5-8 times. Even that seems optimistic, but the lower end could be right.

Heavy handed policing is not political repression.

And yes, police, gendermerie and the army patrolling in France are armed. There have been enough terrorists attacks in recent memory that this is the norm. None of those weapons were ever used against protestors of any kind ("less lethal" ones have been, sometimes to lethal or crippling effect to innocent bystanders or protesters).

And my ADHD (rather severe) is both a disability and an illness, and it sucks. It affects my wellbeing in all possible senses and I know it without projecting blame on some virtual "others". It can be even mitigate with medicines, because it is literally a disorder throwing off my internal body chemistry balance off.

It is no different than say diabetes T2. Both are diseases which are caused by wrong levels something essential, both can be mitigated by a treatment which changes levels of that something. Both have significant societal impact on a life of the affected person. Yet, there is no doubt in the social networks that T2 is an illness, while ADHD is for some reason not afforded as much.
by mrtksn | 2025-04-28 08:15:47+00:00
The police is not always present and you don't have to attack anybody. For most cases it is good enough to be able to show credible defence. If you you are able to smack someone, they will get smacked if they insist and remember it even if afterwards you go through legal trouble(they will also get into legal trouble). Police and the courts cant un-smack them. As a result, people feeling causing trouble tread more carefully and don't cross a line unless they are fully motivated to go through all this.

Streets are significantly more polite than the online places and I think its because of the dynamic of it and not the people - they are the same people.

I do not think he ever was. As you note, most of the 'accusations' come up without any real evidence. It is all basically the same story as with most remote diagnosis of all politicians that 99% talk show hosts play with their audiences.

> "Nowadays people have an implicit understanding that the net is vast and infinite, it's beyond the ability of one man to fully catch up, and you're just tuning into a slice of the data stream".

This is beautifully written, and condense enough to explain to anyone why we're burnt out with consumption.

Your full comment is spot on, and like you, I don’t have a perfect solution. Digests are a good idea, but there’s always going to be some kind of bias, whether it’s set by you, by an algorithm, or by another human. I think the real challenge is to create a digest that gives you a personal, meaningful view while still leaving the door open to a wider context. But if you lean too far into broadening it, you risk losing that sense of ownership and relevance. It’s a tough balance.

Maybe so, but it's still important to callenge okeuro49's claims. Extremist takes like that give off an air of believability despite being unsubstantiated. Relying solely on the common sense of the readership leads to situations where extremist views simply drown out the rest. It should not be seen as acceptable to present a wilfully distorted view of the facts.

> Furthermore, depending on how willing the firmware of your modem is, the signal used to transfer GPS coordinates to the carrier for emergency response situations can also be triggered remotely by carrier hardware.

It should be feasible for an operator to issue a command to the (e)UICC (SIM) in the phone to fetch the current location from the modem and send it back via SMS. At least this was the case for a relatively long time.

Not that it _really_ matters because most people willfully give away their location information to Google anyways. There's a reason why Google has the best Wi-Fi AP -> Location database that they provide commercially. Send them a list of Wi-Fi BSSID's and their associated RSSI's and you'll get a fairly accurate location.

In comparison, using Cell ID's for geolocationing is finicky. In dense urban environments, you're likely looking at ~500 m radius of accuracy - at least based on the commercially available options.
by rellfy | 2025-04-28 08:19:56+00:00
Thanks!

That's a good question. Currently, there is one way to do it. The client querying the agent receives JSON-encoded values that are returned from plugin function calls made by the agent. These values are received alongside the agent token response stream (via SSE). So plugins can essentially emit events that the client can forward to the UI application, such as to click a button etc. The limitation with this is that there is no built-in way to send a success/error status back, it's one way only. It works well for actions that are infallible such as simple UI actions.

The client here would also need a way to interact with the target program of course, e.g. from a JavaScript browser you can click buttons and manipulate the DOM, or from a VSCode Plugin you can interact with the editor etc.

It's definitely something that can be improved though! I've been thinking about some type of MCP interoperability that could maybe assist with this.
