And what happens when someone under that age needs to anonymously ask for advice on the internet?

Most folks hit puberty at around 13. Imagine your parents have divorced -- your new stepfather is very religious. Your phone and laptop have spyways ("parenting software") on them. You manage to get onto a terminal at the public library. You've missed your period -- you're afraid you're pregnant, and not sure how much time you have to do something about it.

There are so many edge cases where the benefits of access to social media outweigh the harms -- but we've framed this as a discussion about selfies and sharing when it's really about free expression, and there are so many dark turns a young life can take that are made darker if they're left to their family and friends to rely on for help.

Don’t get big, get dense. There is a 2-3 x power proficiency.
Go for twelve rep maxes and intensive pyramid sets when you are ready to transform into a dense durable light weight build.

Real strength comes from the relationship between your mind, your body, and the center of gravity of whatever you are moving. Learn strength to stabilize and “the fulcrum” to carry with ease and you will be physically transformed into a super being.

Don’t forget the cardio.

I noticed that too, and I can assure you it’s purely organic. I’m just as surprised as you are!

I suspect the project might have been shared in some FreeBSD or Rust-specific IRC channels or forums outside of HN, which brought in people who aren't regular HN users but are passionate about these specific technologies.

It’s exciting to see new faces, but I definitely didn’t expect this level of influx!

Here's a paper: https://www.jstage.jst.go.jp/article/lsj/50/7/50_394/_pdf

This is a study of the Ushio Care222 unit, but its underlying physics is the same as any other KrCl excimer lamp, so its pretty implausible for other KrCl lamps to exhibit spectral drift when this one doesn't.

The spectrum does change a bit over time--it actually gets less dangerous. But it's a very slight difference.

I can promise you there are no agents or bots here—just a solo dev who's been working on a Rust shell for FreeBSD in his spare time.

I think the 'weird' influx of new accounts is likely because this got picked up by some FreeBSD/Rust communities or Telegram/IRC groups where people aren't usually on HN. It’s my first time posting a project here, and I'm honestly just trying to keep up with the technical questions!

If anyone is skeptical, I'd much rather talk about the code, the job control implementation, or the FreeBSD porting process. That’s why I’m here!
Show HN: Quick Beats – minimalistic webapp (mobile and desktop) drum machine
by gaigalas | 2026-01-15 01:20:32+00:00
Made this for myself.

I'm always picking up the guitar or bass during the day and playing something, and I dislike metronomes, preferring real drum beats as a backdrop.

Now I can just load it up on the phone or notebook and play along.

The beats are also easily shareable. All you have to do is copy the URL. For example:

https://alganet.github.io/quick-beats/#120|4/4|black-pearl|1...

Any feedback is appreciated!

The designs made in the 90's were relatively inefficient which is one reason why they're noisy. But at the same time: it's impressive that a turbine from those days is still up and running today and that says something about the engineering that went into that thing. Lots of lessons have been learned and a modern turbine is so quiet you can stand right underneath it and barely hear it, which I find absolutely incredible. A 75 meter diameter rotor intuitively should make a lot of noise, but they really don't. The main driver is the precision with which the filament is laid on the blade was well as how close the back edge of the blade approaches zero. That's the biggest source of noise and you'll always have some either because you don't quite get there or because you do and the back edge starts to flutter. It is one of those very annoying engineering trade-offs where you're damned if you do and damned if you don't.

Work out the tip speed on one of those big machine and you'll be even more impressed.

I donate to specific projects through OpenCollective. I do not want Github to take extra money from me and then redistribute it to projects I don't care about according to some formula that will inevitably be exploited to get free $$$.

If you want to support a project, submit a PR or send them a check. Don't force me do it for you.

Yes, the same way is that Fortran is faster than C due to stricter aliasing rules.

But in practice C, Rust and Fortran are not really distinguishable on their own in larger projects. In larger projects things like data structures and libraries are going to dominate over slightly different compiler optimizations. This is usually Rust's `std` vs `libc` type stuff or whatever foundational libraries you pull in.

For most practical Rust, C, C++, Fortran and Zig have about the same performance. Then there is a notable jump to things like Go, C# and Java.

From the rapidly changing letters during generation, I can only assume this is powered by a custom text diffusion model, not a boring old autoregressive transformer. (because clearly this would show up in the front end.) Text diffusion is hot right now, are you selling equity? Since its already in production, probably series A- valuation of 2 billion sound right?

Of course I judge, and I expect other people to judge me. It is what we do every day: we assess, evaluate, and draw conclusions. What people have problems with is not to be judged per se, but judged negatively: "oh, please stop judging me as a brilliant, awesome, good-looking person!" is something that, in fact, nobody never said.

The way that the comment I am answering comes across is quite reactive in nature and too forceful in tone.
Nowhere I said that people should dress in a suit or sundress or that they should have visible abs. I do, but that is just my preference.

I just expressed my opinion that, when left to their own devices, people are often apathetic. Or maybe, as the writer of the comment suggested, they (some, to be clear, but in my opinion, too many) choose to be 400 pounds, not showering, dressing in PJs, or doomscroll, because that's the way they are happy.

Good for them, they surely live a life of fewer preoccupations.

> You're labeling someone a "Nazi nut job" over nothing.

Nothing except his antisemitic tweets, his posts defending Hitler, his support of Alternative for Germany, his support of prominent white supremacists, his chatbot which praises Hitler, his endorsement of racist conspiracies, and the occasional "Sieg Heil". What exactly would "something" look like to you?

Being morally superior to that is an exceptionally low bar to clear and it's earned easily by everyone who rejects the hate and lies he publishes, supports, and encourages.

Nah--use 254nm for that. It's a standard thing, if it's contained in a duct it doesn't need to be fancypants human-safe 222nm.

Ducting it kills most of the effectiveness though--now you have to move air through your ducts in order to treat it, so you only get as much treatment as you move air--usually not very fast or else it would be loud and annoying. You can move it faster, but then you need more UV since the faster-moving air won't be exposed for as long. Honestly, upgrade to a MERV-13 filter before thinking about residential in-duct UV

In-room UV is a different story--since it exposes all room air, pathogens start getting inactivated as soon as they're exhaled. The whole room becomes a disinfection reactor.

> it doesn’t look like he said it was a measured harassment report.

If splitting hairs, he originally framed the response as 'kill the messenger', implying there was no other reason for them be offended by it, misleading at least.

> Anyway I don’t know what’s going on here but “Sparkfun has ceased its business relationship with Adafruit because a guy called us jerks in a complaint about our CEO” would be hilarious

I agree, in isolation- it seems reasonable to end a business relationship with any rude or hostile partner regardless, but hiding such a decision behind a CoC rationale just for being called jerks would indeed border on 'hilarious'.

In this case, the claim is that the note was also sent to the ex-employee's partner's current employer, which enters less-hilarious territory towards borderline harassment, not a private HR complaint but public defamation.

Taken as one instance of a broader, ongoing pattern of targeted harassment of several individuals, the combined set of public complaints make the CoC reference not at all amusing.

The '22 ranger tows up to 7500, payload 1500. Sure, bed is only 5-6 feet, but is 4x4, and interior feels good, and is about as bougie as the big F gets. Had it down to 12L/100km, a full tank gave me a 700km range at that point. Fits my family of 5 when it needs to. I would buy one again e-z.

Grabbed it in '25 with factory warranty still on it for about the price of a new maverick.

Is opencode that much better than Codex / Claude Code for cli tooling that people are prepared forsake[1] Sonnet 4.5/Opus 4.5 and switch to GPT 5.2-codex ?

The moat is Sonnet/Opus not Claude Code it can never be a client side app.

Cost arbitrage like this is short lived, until the org changes pricing.

For example Anthropic could release say an ultra plan at $500-$1000 with these restrictions removed/relaxed that reflects the true cost of the consumption, or get cost of inference down enough that even at $200 it is profitable for them and they will stop caring if higher bracket does not sell well, Then $200 is what market is ready to pay, there will be a % of users who will use it more than the rest as is the case in any software.

Either way the only money here i.e. the $200(or more) is only going to Anthropic.

[1] Perceived or real there is huge gulf in how Sonnet 4.5 is seen versus GPT 5.2-codex .

The positioning makes sense, but I’m still somewhat skeptical.

Targeting power, cooling, and TCO limits for inference is real, especially in air-cooled data centers.

But the benchmarks shown are narrow, and it’s unclear how well this generalizes across models and mixed production workloads. GPUs are inefficient here, but their flexibility still matters.

When does it become enough for the fence sitters?

What does it take? Donald Trump asked NATO to help us invade and take Greenland. The Euros that met with him said 'it's time to take up drinking' after the meeting.

What line is too far for you? This is our President doing this stuff, you act like it's some stupid kid off on the sidelines.

Before you argue some BS, the USA has WAY LESS soldiers stationed in Greenland than we did during the cold war. It isn't a serious concern, and if it was, we could...staff to the levels we previously did and that were welcome to be in Greenland.

People stop visiting crappy pubs if they have diluted drinks (quite rare, UK is very strict about being served exact alcohol measures, there is very little free pouring in the UK and many people would spot other drinks being diluted), crappy food (sadly all too common), loud music (age related), etc.

But not many pubs are crappy in these respects.

The main reasons why fewer people are visiting average or good pubs are:
* cost of living is going up so many people have less disposable income
* the younger generations are much less interested in alcohol than previous generations

The latter point is an interesting one. There are two wildly different drivers for this that I’ve witnessed.

Many of the under 25s now either don’t drink alcohol at all, or only drink a fraction of what their elders did. Many prefer to just go to the gym instead (which is the millenials third space).

On the flip side, some of the children of my friends and family say that alcohol in pubs is just too expensive, so they get their kicks from recreational drugs like weed or ket.

The number of people who have the disposable income to go to the pub regularly is falling in the UK, and the mainstay of the pub was often the working class and they are being priced out by everything getting more expensive.

There aren’t enough people with enough disposable income to weather the storms and keep going to the pub regardless, and therefore pubs (in general) are in deep trouble.

one nice thing is that if you represent the state as a permutation matrix P, and have a matrix of starting piece locations x, rendering is just Px. Then, for smooth rotation animations, if your move is a permutation M, animation is just expm ( t logm( M)) P x with t going from 0 to 1

It's worth noting that the premise of the article- that low cost Far-UVC could not easily be purchased before the Aerolamp, is false.

While AeroLamp has put a proprietary Ushio emitter in a 3D printed enclosure as a sort of reference model to encourage the use of Ushio components, third party tested Far-UVC has been sold for several years now by Nukit222.com at a fraction of the price of any competitor.

Our approach is somewhat different. We use no IP-encumbered components, all parts that can be purchased from any of a dozen Shenzhen factories, we put the product firmly into the Gongkai ecosystem (https://www.bunniestudios.com/blog/2014/from-gongkai-to-open...) without being at the whim of a single high-cost proprietary central component the manufacturer can reprice at anytime.

By focusing on non-IP-encumbered designs that are basically shanzhai-able-"Temu friendly", and then validating the market for those products, you virtually guarantee it will be picked up, copied and improved upon- meaning lower costs and wider distribution.

If you want to make a fit-for-purpose product, faster, cheaper and at larger scale than the Shenzhen Hardware ecosystem iterating at Shenzhen speed with shanzhai- best of luck to you.

The central remaining issue is safety and efficacy, which is why we post all our third party lab tests, for all our products, for download on the sales page. Ozone output, pathogen chamber tests, full spectral assay for safety and power output, UL CE etc. We were the first company to do this, and push for all companies to do the same.

> I'm building Fullstack AI for Defense

Yeah, I think this could be taken to a billion-dollar idea within a couple of months, if the implementation is decent.

Full-stack would probably mean, in context, something from Palantir-style data-mining and aggregation, through logistics/legal/command/etc., all the way to autonomous systems operating on the front lines.

I don't think that anything of this sort actually exists yet? I imagine it could exist, though, especially in smaller countries that feel threatened, and which have fewer layers of bureaucracy, e.g. Estonia.

I am of the opinion that Nvidia's hit the wall with their current architecture in the same way that Intel has historically with its various architectures - their current generation's power and cooling requirements are requiring the construction of entirely new datacenters with different architectures, which is going to blow out the economics on inference (GPU + datacenter + power plant + nuclear fusion research division + lobbying for datacenter land + water rights + ...).

The story with Intel around these times was usually that AMD or Cyrix or ARM or Apple or someone else would come around with a new architecture that was a clear generation jump past Intel's, and most importantly seemed to break the thermal and power ceilings of the Intel generation (at which point Intel typically fired their chip design group, hired everyone from AMD or whoever, and came out with Core or whatever). Nvidia effectively has no competition, or hasn't had any - nobody's actually broken the CUDA moat, so neither Intel nor AMD nor anyone else is really competing for the datacenter space, so they haven't faced any actual competitive pressure against things like power draws in the multi-kilowatt range for the Blackwells.

The reason this matters is that LLMs are incredibly nifty often useful tools that are not AGI and also seem to be hitting a scaling wall, and the only way to make the economics of, eg, a Blackwell-powered datacenter make sense is to assume that the entire economy is going to be running on it, as opposed to some useful tools and some improved interfaces. Otherwise, the investment numbers just don't make sense - the gap between what we see on the ground of how LLMs are used and the real but limited value add they can provide and the actual full cost of providing that service with a brand new single-purpose "AI datacenter" is just too great.

So this is a press release, but any time I see something that looks like an actual new hardware architecture for inference, and especially one that doesn't require building a new building or solving nuclear fusion, I'll take it as a good sign. I like LLMs, I've gotten a lot of value out of them, but nothing about the industry's finances add up right now.

My claim is not that lenders are dumbasses that keep taking losses, that's your claim.

Lenders are not some homogeneous static group like you imagine them to be. There are many different kinds of lenders (including "creditors" that lend no money at all), and there are constantly new lenders coming into the market all the time, many of whom are not yet sophisticated enough to grasp the risks of lending to PE-owned companies.

My claim was that individual lenders either stop lending to PE firms outright or jack up the interest they charge to PE owned businesses once they have suffered PE-related losses of the kind I described above.

Lending is about risk management, and interest rate pricing is based on the estimated risk of a loan not being repaid. PE-owned companies are considered extremely high risk by most lenders due to the types of shenanigans PE firms pull on a regular basis. It can take over a decade for a PE firm to develop the reputation that would allow the companies it owns to get debt financing on terms anywhere close to what a non-PE-owned company can get. This is part of what killed Toys'R'Us; the interest it had to pay for its debt financing post-PE acquisition exceeded was materially greater than the interest it paid for the same amount of debt financing prior to the acquisition.

As a followup, Saks declared bankruptcy this week, after a sequence of events that began with their PE investors ladling up Saks with debt to pay themselves dividends, added more debt to acquire another company (which resulted in the PE firm getting paid management fees for the "successful" acquisition), and then spun out the debt-ridden conglomerate so it was no longer their problem. In this case, the financial institutions that funded the PE shenanigans mostly got paid off after Saks had to sell one of its most valuable, landmark locations a few weeks ago. The "lenders" that got screwed this time were their suppliers that provided them inventory on credit (like Chanel, etc). Many of them had already stopped providing new inventory to Saks due to the unpaid balances.

When young I use to work in construction. (With diplomas) The wages for 18 year olds in the Netherlands at the time were such that I got 340 euro per month for 40 hour weeks. It's a truly shit salary but you could also see it as a wonderful formula to build cheap houses. As my boss billed the customers 28 euro per hour for my work and those houses cost roughly 35000 to buy(!) and it took roughly 80 hours of work each. (Very rough estimates but that oddly doesn't matter) You could say I build 6.4% of the houses. They roughly cost 350 000 euro today which seems 10 fold but since people can't afford that they need a mortgage and pay 3 times that amount over 30 years. That would mean my labor now costs 10 000 per month. At the time I tried to calculate the savings escape velocity and discovered that if I saved 100% of my income I would be able to buy my own house in never years. If I build 6.4% of a house in 2 weeks that would be 3.2% per week or 32 weeks to build 100%.

Say 64 weeks and the process produces one whole home for someone else. I get that there should be some people between the construction worker and the citizen eventho they never did anything useful to the result but the margins are so preposterous that the original salary is a mere rounding error.

Then I look at Amish barn raising videos and the laughter becomes uncontrollable. I would definitely go there and help out - for free of course. If I had to keep doing that I would look for some vegetables and uhh my own house? Even if they would never build it for me it would still be more enjoyable than the western extortion scheme.
