I’ve worked with electron microscopes and in silicon fabs and it’s super fun being on the teams hunting for sources of noise during construction and bringup. In fabs there are multiple teams because it’s so specialized, the HVAC team being the most interesting one because they’ve got tons of mechanical and electronic sources all over the buildings. They were also the long tail for problems with yield (which was expected and budgeted for). I think the EM startup I worked for failed in part due to not taking the issue seriously enough.

I can’t tell any specific stories but poorly shielded USB ports were the bane of our existence in the 2000s. Every motherboard would come with them and the second a random floor worker would plug something in it’d take down a section of the fab or all of the microscopes even if it were on the other side of the building. For some god forsaken reason all the SBC manufacturers used by tons of the bespoke equipment were also adding USB ports everywhere. We ended up glueing all of them shut over the course of the several months it took to discover each machine as floor workers circumvented the ban on USB devices (they had deadlines to meet so short of gluing them shut we couldn’t really enforce the ban).
It's more like the door has a weak lock that can be picked. Just like many real world doors do. Here's how it would go in court:

"Are you aware that this key could be used to decrypt information and impersonate X?"

"Are you aware that this key is commonly called a Private key?"

"Are you aware that this key is commonly called a Secret key?"

"Are you aware that it is common to treat these with high sensitivity? Protecting them from human eyes, using secure key management services and so on?"

"Was it even necessary to target someone else's secret private key to demonstrate that 512-bit keys can be cracked?"

"Knowing all of this, did you still willfully and intentionally use cracking to make a copy of this secret private key?"

I wouldn't want to be in the position of trying to explain to a prosecutor, judge, or jury why it's somehow ok and shouldn't count. The reason I'm posting at all here is because I don't think folks are thinking this risk through.

Interesting, I'll have to think about that.
Actually, with rare earth paints, the big issue is persistence, which is rather too long. In the current script, I only turn the drum 1/4 turn, so it takes roughly 4 minutes to illuminate the same patch again. Otherwise the lowest digit tends to be blurred because it is a combination of the last two values.

Yes it seems crazy, but besides the obvious "leak your own key" as other comments mentioned, this is actually possible. This is one of the biggest discoveries in cryptography in the last decades and its implications are still being researched. I dug around and found this article which seems to do a pretty good job describing the cryptographic concepts of "non-transferability" / "deniability" / "deniable authentication" for a lay audience: https://dinhtta.github.io/zkp/ Also: https://en.wikipedia.org/wiki/Deniable_authentication

You are right, I used the wrong wording here. I meant crystals, not powder. I used the word 'powder' unconsciously because when I was raving, I would break those crystals into powder form to control the dosage better.

Anyway, regarding the difference between ecstasy and MDMA, from personal experience, I cannot remember a time when the effects were the same. Every time I took a pill, the effect was totally different from MDMA. MDMA provided a more 'pure' experience, whereas with advertised 'ecstasy' pills, I experienced hallucinations, memory loss, and a very heavy hangover.
Did you install Steam and Epic? It's really stupidly easy to install something like Heroic. Like the same level of difficulty as installing Epic. And it will even add games automatically to Steam for you.
It was not lax, but bent in strange ways.

E.g. FB was banning people for using a historical term when discussing Russian-Ukraine war - „Muscovite“. Which has no derogatory connotations mind you. Besides reminding that modern Russia started as Duchy of Moscow. And to make distinction between Rus/Ruthenian people (e.g. Kievan Rus) and modern Russia. Yet FB considered it hate speech for some god forsaken reason.
Pretty much everything in audio processing is a filter, whether it's called a filter or not, but that's overly reductive. Synthesis is just creating audio from parts.
If you don't play games from Epic Games, GOG, Amazon or local installs, then there isn't much point to it. If you only use Steam, there isn't really any benefits.
Yeah, that's what terrifies me now especially. As far as I'm aware, "cutting" drugs with other drugs is hardly new, but the fact that fentanyl can be made so cheaply and easily and added to everything means that all this stuff is a hard-pass for me now.

Honestly, I'm in my mid-30's, I think that I'm too old to "start" doing this stuff. In a lot of cases (and this is still something I'm not 100% used to), people look to me as the "grown up" in the room, for better or worse.
No of course it won't solve the problem. This is a multi-faceted problem which will require significant investments into multiple areas to overcome. Which looking at current pooling seems unlikely to happen in the next few years.

Oh, I did understand them at that level. I can confirm that that's a pretty good explanation of solar cells and MPPT circuits.

What I meant was that I wasn't confident that I was remembering the open-circuit voltage of a silicon solar cell, and in fact I had it wrong—it's not 0.7 volts, but 0.5 to 0.6 volts. And I couldn't remember if the diode junction was forward-biased or reverse-biased in normal operation. It's reverse-biased—the photocurrent goes the opposite direction from normal diode current. Now that I think about it, maybe that's why shade on one cell knocks out a whole string.

One quibble, though: if you maintain 12 volts in the usual direction across a series of 10 monocrystalline silicon solar cells at night you are just going to lose a subthreshold leakage current through them, because you're forward-biasing the pn junctions in the cells, just not quite by enough to turn them on. They'll emit a little bit of infrared light, a feature used to analyze solar panel failures (so-called "EL testing"). Illuminance at night is at best a million times dimmer than sunlight https://en.wikipedia.org/wiki/Orders_of_magnitude_(illuminan... and that subthreshold dark current is not going to be a million times lower than your normal current. Even under indoor lighting, which is only about 2000 times dimmer than direct sunlight, monocrystalline silicon PV cells will consume power rather than producing it.

Because of the intermittency you're describing, I suspect that thermal energy storage of various kinds (sensible heat, phase change materials, or especially TCES) is going to be important for the wide adoption of solar power, because according to my notes lead-acid batteries store about 20kJ/US$ and LFP a bit less, while industrial calcium chloride costs about US$300 per tonne (US$272/tonne according to https://derctuo.github.io/notes/desiccant-climate-control.ht...) and can absorb about its own mass of water from the air, liberating the water's enthalpy of vaporization, providing TCES.

I believe the heat thus stored is 408kJ/kg (see linked notes) which works out to 1500kJ/US$ at that price, roughly 1% of the cost of the same energy storage capacity in a battery. And, depending on the desiccant, it's plausible that you could reduce that by another order of magnitude, or two orders of magnitude for industrial installations. You can probably get by with impure calcium chloride or as-mined carnallite, for example.
The idea is to use a MAC instead of a signature. As long as Alice isn't compromised and sharing her key with Mallory (which she could do even in the signature case), when Bob receives a message with a valid MAC on it, he knows that Alice authorized the message.

To be fair, this is a deal I would totally take, at my normal consulting rates. I'll be slower than Rust superfans, but I'm probably cheaper too.
Deniable Knowledge
RSA-1024 is "only" 80 symmetric equivalent bits. It's a space requiring a tremendous amount of energy to explore, though I personally consider it very likely that the NSA and/or the MSS et al. have poured immense funds into accelerators specifically targeting RSA, and for them there'd be no obstacles at all to be granted an allocation for such energy consumption.
> I'd love to work in a fantasy company that allows for fixing legacy code

You're not supposed to ask. It's like a structural engineer asking if it's okay to spend time doing a geological survey; it's not optional. Or a CFO asking if it's okay to pay down high interest debt. If you're the 'engineer', you decide the extent it's necessary
So the answer is "No, this is not accurate?"
I went traveling for much of 2024 and I wanted a universal charger and powerbank that just worked without issues. I also didn't want to carry around two different things so the best option I found was this combined universal charger and powerbank called the SnapWireless PowerPack Universal Pro, it is a brick but it has a 15k mAh battery with wired and wireless charging and also comes with attachable plug adapters. It saved my ass more than a few times when I was running out of juice for my devices.
> You have effectively gone out immediately after reading the article and proven the article's larger point.

You must misunderstand my position, because I don't really disagree with the article overall - it seems plausible to me. Just that it uses an over-complicated explanation for one of its points.
NPR did a recent expose about a local renegade spot & the shows it supports in my scene:

https://www.kuow.org/stories/under-the-bridge-a-portrait-of-...

With mixed results, it kind of burned the spot by virtue of being talked about in too wide an audience but I think it's also important to make it known to the mainstream that this kind of stuff is happening.

All that's needed to make a rave happen is music & speakers, scale and quality is all configurable. Humans will always find spaces to congregate: whether it's their own houses, local parks, abandoned warehouses, industrial districts, or deep in the woods.
I hope we're not losing our drive to be around eachother and dance, it's been such a integral part of my life story (as a fairly young person!) and has let me find my people.

The browser engine is not what makes Firefox "relevant" or not. Their competitors are Apple, Google and Microsoft. The marketing budget for Chrome is larger than Mozilla's entire budget. "Google" is synonymous with the entire internet for a large fraction of the non-technical population. Every device you could buy on the market whether a PC, a tablet or a phone has one of their competitors browsers already pre-installed.

Their primary leverage is unique features and functional adblockers, neither of which is impacted by the layout engine.

And again, you're taking away resources from something that is already behind right now. The canonical example of massive long-term rewrites being a bad idea for the business is literally the precursor to Firefox. Gecko can be refactored in-place, including into Rust if they decided to do so.

Show HN: Awra – AI-powered legislative bill analyzer
I built Awra to solve a simple problem: understanding what bills in Congress actually mean for regular citizens.

What it does:
- Explains federal bills in plain language
- Shows state-specific impacts
- Provides cost analysis when available
- Uses AI to answer questions about any bill

I've found that while tools like ChatGPT can explain bills, they often hallucinate or work with outdated information. Awra directly fetches from Congress.gov's API and uses RAG to ensure accuracy.

Try it out: https://www.awra.ai
GitHub: https://github.com/reacthor-ai/awra

Looking for feedback, particularly on accuracy and usefulness. Would love to hear from people who regularly need to understand legislation.
I do not know how that would be possible with the technology used, but having a deeplink to a planet or object would be cool à la https://atlasof.space/Nix
And if flimsy parts and design-for-manufacturing rather than design-for-repair aren't done intentionally to increase sales through replacements and/or to optimize for minimal cost, then it's done through negligence.

Show HN: FormML – A DSL for building forms (like Prisma but for forms)
Over the years, I’ve encountered many challenges while building complex forms from scratch - challenges that I believe are common, difficult, and yet often overlooked.

While there are many awesome tools in the ecosystem for building basic forms, like Formik and React Hook Form, there isn't yet a serious solution (to my knowledge) that specifically addresses these pain points of complex ones.

Finally, this led me to come up with my own solution FormML (Form Modeling Language) that specifically addresses "enterprise-level" form needs.

Looking forward to your thoughts and feedback!

Wow. In my undergrad all engineering majors had to take linear algebra (calc 3 was optional for computer engineering).
I'm not even sure it's an 'or' at this point; I've recently gone (multiple times) through the surreal experience of having to install a client and register an account having already bought a game through a storefront for which I had to install a client and register an account and which had already ostensibly installed. In the first case it was for a game I had actually previously played before the publisher decided to slap an account on top of its offering, and I decided I didn't care enough to keep going.
> Maybe we just don't want to bro.

There's nothing wrong with it (quite the opposite), but keep in mind that this is not a normal thing. Most generations didn't act like this.
> More centralized government control, "Karen" style moralizing, DEI, gun banning, global warming, more bureaucratic (and ineffective) regulation, abortions everywhere and the entire "woke" platform apparently isn't it.

I totally agree with that.

> The way to win is with a more appealing set of policy proposals.

I completely disagree with that. At this point I think it's a bit laughable to think that the majority of Americans care about policy proposals. Trump's appeal, I believe, is that he gave a voice and an outlet for anger to large swaths of people who felt they had been ignored (which they largely had) and talked down to for years. The "elites" (often of both parties) had basically told people in hollowed-out communities and those with failing economic prospects that it was their fault - you just should have gotten a college education, or retrained for the new economy. The Democratic messaging made things worse by also saying "Hey, you know those social standards that were the norm up until the mid 90s? Well, if you believe those, you're a knuckle dragging bigot."

When people have simmering anger and rage, a "nice guy" approach isn't going to cut it. That's why so many people vote for Trump even when they find so many aspects of his personality distasteful.

I'm baffled why a politician hasn't taken more of the lead with the rage that has exploded since the CEO murder. Some elites on the right are trying to frame this as "The crazy Left condones murder!", while I see some elites on the left doing their usual useless finger wagging against insurance companies (see Elizabeth Warren). I just don't understand why a politician hasn't taken this torch and gone into "We're going to tear it all down" mode. I mean, of course there's Bernie, but at this point it needs a younger and more "firebrand" type of person.
Might want to disambiguate “nothing” too… just as in the poem lots of things happened to lots of people; lives started and lives ended, fortunes were made and fortunes were lost, and even if nothing else happened the end of democracy crept a day closer.

Arguably that nothing that didn’t happen is infinitesimal compared to the nothing that did.

At least on Apple and similar with inductive charging designs, there's nothing to break. (Repairability of the rest of it, notwithstanding.)
It would indeed be hard to convince me Trump has not committed crimes, considering a jury found that he had and the whole, "Walks like a duck, quacks like a duck," thing. Tony Accardo ran the Chicago Outfit for 4-5 decades and never spent a single day in jail. I don't think most people would agree that because he was never convicted (or even charged), he was not committing crimes.

If you read a story about a drug kingpin being convicted at trial, do you assume that he might be innocent?
This is so awesome. I've wanted something like this where you could visit all scales of the universe from tiny atoms, to the galaxy, to the broader universe. Does something like that exist in some form?

For sure, I think this does however line up with even younger folks who aren't going to generic clubs for a late night. They would just start earlier, bars/etc. and then end earlier. The full night bangers are definitely still very viable (and as crowded as you would like them) in NYC
