I was thinking the edge could have a radius of about 350μm (like 21-gauge wire) while the main body might be 200μm thick.

Price is always an issue. Maybe you're willing to pay €100 a spoon, or €1000, or even €10000, but nobody is going to pay €1000000000 per spoon. If there's a good chance the price will drop by a factor of 10 in the next year, many rich people might be unwilling to pay even €100.

The process described sounds like it would currently be able to produce a spoon for a cost on the order of €100k: four PhDs working for a month is maybe €50k, but they're also tying up a lot of rather expensive lab space, and I think they're using analytical-grade fine chemicals rather than metallurgical-grade copper and tantalum. And in this study they made roughly enough for half a spoon. The second spoon would probably cost closer to €1000.

I've got no idea what you're going on about, but 97% of the Earth isn't empty in any useful sense. For starters, almost 70% is ocean. There are also large parts which are otherwise uninhabitable, and large parts which have agricultural use. Buses don't go to uninhabited places, since that's costs too much. Every five minutes is a frequency which no form of public transport can afford.

Yeah, any tracking expands the surface for surveillance, whether it's for subscriptions or for safety.

Market incentives make subscription tracking likely to become more and more all-encompassing, though. (like with "Smart"-TVs) That's a dynamic absent from safety tracking.

OTOH, safety tracking is politically much harder to push back against because it's framed as a protection or safety feature. ... hard to tackle if it's there by law in some global juristictions.

We imagine 3 use-cases with Flowcode: - Non-developer, but technical roles (IT, Automation experts) using it as a more powerful and flexible alternative to n8n.io/make.com - Technical product managers using Flowcode to integrate AI-based flows into their product and collaborating on them with developers - Experienced developers building LLM-heavy (or any other async/concurrent heavy logic actually) looking to build faster flows

The original article is behind a paywall so can't really read through it. But am guessing its something to do with the trade war with China. Alternative information source suggests it has something to do with sellers who import from China are pulling off from the Prime Day.

> Tariffs on sellers' goods are putting Amazon in an awkward position for Prime Day, said Arun Sundaram, an analyst at CFRA Research.

Something to consider if you haven't yet: have you checked that your website hasn't been compromised? I've seen something similar happen to a domain that got their WordPress hacked and was used to host malware.

I think it's also possible a large amount of people on Outlook (or LinkedIn?) lost interest and clicked "report spam" because it's quicker and more effective than unsubscribing from most automated messaging.

Edit: another thing I caught O365 doing was rewriting the headers in my email (it didn't like the way my From:-address was structured by my server) and then checked the DKIM headers. Obviously the email they altered themselves didn't pass the DKIM signature check. Worked around it by altering my email client to set the From address in a way that Outlook liked.

> If there were firmer ideological underpining to the right's platform, I'd be willing to listen.

But there isn't and will never be imo, as human behavior cannot be hard-categorized into easy to understand boxes. Just as a light example, look at the former D's that were appointed and confirmed by the current administration. Would you say they have accepted a level of the Right's conformity over their original/core beliefs?

Perhaps briefly. Companies tried this with offshoring support. Some really took a hit and had to bring it back. Some didn't though, so it's not all or nothing in the medium term. In the short term, most of the execs will buy into the hype and try it. I suspect the lower quality companies will use it, but the companies whose value is in their reputation for quality will continue to use people.

> it can destroy value of entire sectors. Think of resume-sending. Once both sides are automated, the practice is actually superfluous

"Like all ‘magic’ in Tolkien, [spiritual] power is an expression of the primacy of the Unseen over the Seen and in a sense as a result such spiritual power does not effect or perform but rather reveals: the true, Unseen nature of the world is revealed by the exertion of a supernatural being and that revelation reshapes physical reality (the Seen) which is necessarily less real and less fundamental than the Unseen" [1].

The writing and receiving of resumes has been superfluous for decades. Generative AI is just revealing that truth.

Show HN: A Chrome extension that will auto-reject non-essential cookies
by mitch292 | 2025-04-29 11:49:55+00:00
A FOSS chrome extension that attempts to remove the annoyance of cookie pop ups and banners.

There are some extensions out there that auto-accept cookies, but I didn't find one that auto rejected cookies without either chaining some extensions together or setting up custom rules in tools like uBlock origin. So with this extension, you just need to add it for non-essential cookies to be rejected.

Github: https://github.com/mitch292/reject-cookies Extension Link: https://chromewebstore.google.com/detail/bnbodofigkfjljnopfg...

It's still very early days for the extension. I want it to keep improving and working on more and more sites. Feedback welcome. Thanks!

I had a slightly better experience on my PhD in Central-Eastern Europe. My supervisor - a politician with little academic results mostly cared about the formal part of my results.

I used the PhD to get into a new field (statistics) just in time for me to get into Data Science as it started being cool. My papers weren't interesting, but I got to try things out on real data and report on them.

I'm a bit worried about the social impacts.

When a sector collapses and become irrelevant, all its workers no longer need to be employed. Some will no longer have any useful qualifications and won't be able to find another job. They will have to go back to training and find a different activity.

It's fine if it's an isolated event. Much worse when the event is repeated in many sectors almost simultaneously.

I'd have been much more interested in a take that reversed the causality. For a bit now being a nerd has been cool — are we witnessing the reversal of that trend now nerds aren't the underdogs?

(Not that I think many people consider Tate cool either — GenZ has its own subcultures that don't align well with the 80s American jock/nerd divide.)

It will backfire if they don't do something nobody has ever done?

How does that work?

I think you mean that Trump people will get mad at them for highlighted his screwup. I'm sure that's true -- they've decided to back Trump no matter what, which leads them to numerous irrational positions -- but it's not like Amazon or anyone else can do anything about it. Trump and his supporters just thrash about destructively and we all pay the price.

Over half of Amazon's third party sellers are Chinese companies who regularly false report to dodge tariffs on their products in ways that American competitors can't. Amazon claims to police them but they're extremely reliant on them at this point and the Chinese sellers just start up new brands if penalized.

>Except of course it's the only perspective I ever hear about, so I'm not sure who this mythical "no one" is.

Most American primary/secondary textbooks (in a country where the majority of people still don't go to college). Ask the average person to name an Islamic analogue to Newton, Copernicus, or da Vinci, you're going to get blank stares. I couldn't do it, and I watched Family Guy Cosmos and everything.

Lowering the barrier of collaboration is indeed a major goal for us. In the DRAKON analogy, Flowcode might help technical product managers collaborate with developers on LLM-heavy logic.

In Kagi you can search with a specific country selected or the default "international".

I find it a superior alternative to Googles "wherever you are", but I do a lot of multilingual searches. For example, when I'm searching for french recipes, I don't want crappy American SEO optimized recipe agregators. Selecting the country I live in brings up local laws instead of stuff from other (bigger) countries where the same language is spoken. International works very well for code and general queries.

Is there a good way to select visually distinct colors? It's easy to do one self if it's only a few colors, but it gets particularly hard the more than 6 or so colors. I have a use case where I need up to 20 or 30 visually distinct colors, and it's hard.

> The SSE spec has an event id and the spec states sending last event id on reconnection.

Last event ID is not mandatory. You may omit event IDs and not deal with last event ID headers at all.

More importantly, the client is sending the last event ID header. Not the server. The only state in the server is a list of events somewhere which you would have to have anyway if you want clients to receive events that occurred when they were not connected or if you allowed clients to fetch a subset of them like with long-polling.

So there is really no difference at all here with regards to long-polling

> Texas

That’s because there is no effective regulation of the state’s power industry. Since they’re (mostly) isolated from the national grid, they aren’t required to listen to FERC, who told them repeatedly that they should winterize their power plants. And a state-level, the regulators are all chosen by the Governor, who receives huge contributions from the energy industry, so he’s in no rush to force them to pay for improvements.

The real irony was the following summer during a heatwave, when they also experienced blackouts. Texas energy: not designed for extreme cold, not designed for extreme heat. Genius!

I miss the food in Texas, but that’s about it.

I'm primarily a macOS and Linux user, but I do have a 2nd work laptop and a VM I use for Windows, both of which I upgraded to Windows 11 2-3? years ago.

There's never been an issue. It's a better experience than W10 was. I don't really understand why everybody is upset.

I don't play video games so maybe that's part of it?

You can skip ahead full units by passing a test, and I recommend always doing it if you can.

I do 1-2 Duolingo lessons daily, supplemented with 15-30 minutes of real Japanese study. If I can't skip ahead after completing the first "star", I feel disappointed. I'm often able to skip two or three units in a row.

Though this is partly because I'm only using Duolingo as an easy, gamified supplement to serious study.

I wonder if they keep this after Trump's gone, especially for countries whose tariffs were high before Trump. I as a customer would prefer they did.

My uninformed guess is that this hurts the bottom line in at least the short term if customers are less likely to purchase an item which sports high tariffs (even if they might otherwise buy the item if the precise tariff were hidden). And the long term benefit to global trade (inasmuch as one sees that as a good thing, which I mostly do) isn't something that's very testable, much less certain.

We thought about it but: - this a statically generated site (SSG using Next.js), so there's backend runtime for the FE itself. - we do have a contact form, but under the hood it sends an email to our own inbox through internal APIs and the destination email is hard-coded, so I don't think they could hijack this (will check the audit log just in case). - it's hosted using Cloudflare pages - the worker/api part is severely rate limited - we would notice abuse since we have low monthly email sending limits on this api service

In the previous year 2023 discussion, the founder says that the update interval was changed to 3 hours. lol. see https://news.ycombinator.com/item?id=35873727

If the update interval had been 1 day+, they probably wouldn't have noticed after one month when they had a 5 minute update check interval.

Wow. On the other side of the table, for system owners it dilutes the meaning of CVEs and causes alarm fatigue. I have a friend who says his npm logs are full of scary CVE/security vulns that are not relevant. The cost of upgrading is high, often breaking changes due to average js package quality, and the only reason is to suppress a spurious warning.

The thing security people refuse to accept though, is that security isn’t a paramount business concern, even if management understands the real risks. Stolen customer data is often followed by an apology and password reset request. Nobody cares, especially in a world where personal and private data no longer exists. Restore from backup, and move on.

Should it be that way? No. But it is. It’s not a security or awareness problem, it’s a business/culture problem. You can’t fix a broken engine with a better taillight.

A lot of being "car brained" is because even the best transit sucks compared to a Taxi.

People objectively don't want to share space with the masses. Even in Singapore or Japan, the stress of being in crowds is simply not worth it. Its slower, requires far more mental energy to plan your route, and requires a lot of physical movement which is hard for fatass americans.

Especially when America has quite cheap, awesomely fast and fun cars (your local C8 Corvette can be had for 15% off MSRP from the factory right now).

Cars are freedom. Mass transit is biopolitics/biopower. Big ass off road capable trucks literally don't even need roads.

NavigationLink is a component SwiftUI developers love. By ingeniously combining the behavior of Button with navigation logic, it dramatically simplifies code. Unfortunately, in certain scenarios, using it the wrong way can create serious performance issues and make your app sluggish. This article analyzes the cause of the problem and offers a practical—albeit slightly mysterious—solution: adding the equatable() modifier to optimize performance.

I've been messing with Claude pretty heavily the last week or so and found if I guide it in the right direction it (mostly) does the right thing.

I've been having it reproduce the lua peg parser thingie (plus utf-8 support)[0] from the paper they wrote about it while also using the 'musttail' interpreter pattern [1] just because that sounded like a good idea. Once I got over the fact that Claude is really bad at debugging and Deepseek, while much better at it, isn't very reliable due to 'server busy' timeouts things have been going swimmingly. While I don't do very much debugging once in a while they do get stuck trying the same things over and over so I have to step in and every so often it'll go crazy and come up with some over complicated solution where I have to ask "that's nice and all but wouldn't it have been easier to just update the index variable instead of rewriting the whole thing?" Claude also seems to like duplicating code instead of generating a helper function but I haven't had that argument with it yet.

So far we have a VM which passes all the tests (which was a battle), a Destination-Driven Code Generation (with additions and subtractions) based compiler implementing all the peg specific optimizations from the paper (which I haven't even starting debugging yet) and the start of a Python C-API module to tie it all together. Admittedly, the python module is all my doing because it's easier to use pybindgen than fight with the robots.

So, yeah, I'm just having fun getting the robots to write code I'm too lazy to write myself on a subject which has interested me for at least a decade. Once I get this working I plan on seeing how well they do with Copy-and-Patch Compilation[2] but don't really have high hopes on that.

Allegedly one of the ways they've been training LLMs to get better at logic and reasoning, as well as factual accuracy, is to use LLMs themselves to generate synthetic training data. The idea here would be similar: generate synthetic training data. Generating this could be aided by LLMs, perhaps with a "playground" of some sort where LLMs could compile / run / render various things, to help select out things that work and things that don't work (as well as if you see error X, what the problem might be).

Popularity polls always showed Polievre as a deeply unliked candidate, even within Conservative voters. It seems like many Conservatives remained loyal to their party while pinching their noses at Polievre, who lost in his own riding. He has not announced his resignation as party leader yet, though.

The leader of the social democratic party NDP did announce his resignation last night as he also lost his seat in parliament.

Lots of change in the upcoming weeks and months.

I just want to make an observation based from previous experiences.

These styles of programming environments are not new. We have seen many such tools in the past. I think they are useful (to an extent) when dealing with high-level compositions such as orchestrating a video pipeline, shaders, simple logic.

They start to fail very quick when you need to implement more advanced algorithms and processes that are not yet abstracted in reusable blocks. Needless to say, it is easier to write code at this point. Just less cognitive load and frankly the visual model does not help when you have a solid mental model - you can keep more information in your head in abstract forms than the eyes can scan and process.

I am lurking in the n8n community and I have noticed similar patterns. The more elaborate workflows are just not as robust as they could be if you write code - and they happen to be very difficult to maintain too and full of bugs.

Other than that... these types of framework have their place and as I said, overall I think they are useful as long as they are used in the right way.

Comprehesible input. find something basic you can understand and immerse your self in it. Often this is childrens books/shows or similar level designed for adults.

at the start you use a translation dictionary to look up ever word which is boring - which is why approaches like duolingo where they give you around 2000 common words to memorize quickly are useful. However the goal is to learn just enough of that list that you can find something you understand to start the real learning on.

This is about Microsoft, a corporation so giant and unaccountable that it's able to hide behind complexity. The OP's email issues may even be a non-malicious expression of that complexity. Nonetheless, the result is opaque power, from which European tech must rapidly divest dependency.

But there is a larger pattern to acknowledge here. It's about unaccountable digital privilege and the ability to wield technology for capricious harm.

This week I've been interviewing US government tech workers about the misuse of the SSA "master death file". If you're in this file you're digitally "deleted from society", after which all credit cards are automatically cancelled, bank accounts frozen, so one cannot get paid, see a doctor, travel or function in US society. DOGE are actively working to consolidate and centralising systems to make it "easier" to nudge undesirables to "self-deport".

In order to do this, huge amounts of illegal activity are already afoot, but most people, including judges, are not technically able to comprehend what is being done or what technofascism looks like.

If we want a "Bill of Bytes", it is going to need some very wise and far sighted thinkers who understand the nature of digital harms, and it will need to apply as much to governments and individuals as to private enterprise.

Existing "cyberlaw", including things like "computer misuse" are looking decidedly stone-age in the face of 21st century "layer-8/9" threats.

My absolutely unqualified opinion is that blockchain will survive but won't find much uses apart from those it already has; while the metaverse- or vr usage and contents- will have an explosive growth at some point, especially when mixed with AI generated and rendered worlds- which will be lifelike and almost infinitely flexible. Which btw, is also a great way to spend your time when your job has been replaced by another AI and you have little money for anything else.

The issue with solar and wind is that when they're being initiated in the project stage, they're advertised as the equivalent of some amount of average power (or even maximum power, if the project initiators want to be disingenuous about it), when the required amount of construction to match baseload capacity would easily be 3-4x that number.

There really is no one-size-fits-all solution, except for having an energy mix of renewables, with existing thermal power on standby.
