This stinks - smells I mean. The timing is just too suspect. Kenvue price tanks upon admin comments that Tylenol is bad, suddenly Kenvue gets bought at a roughly $7 a share premium ($21) vs. the now-tanked price. Mergers take a long time so this was in the works for a while, so I don’t think Kimberly Clark has anything to do with this. One wonders who got the idea to tank the Kenvue stock and then what they did (either on the Kenvue or the Kimberly Clark stock) to profit. Someone should look into this …

Actual applications at the moment are mostly imaging, the 'nudie scanners' at airports and THz imaging at various frequencies is in use for food inspection as it can easily show blemishes/defects in produce that would otherwise be invisible. I read a paper once on detecting counterfeit money. Analysis of airborne contaminants / weather prediction are other possible applications. For telecom it has been considered (at very early stages) for 6G due to the huge bandwidth available. Really there are a lot of 'possible' applications but implementing them has proven difficult either because it requires advancements in materials or other risky aspects or because it's beaten by existing technologies at the moment.

Yes, I am a 70's child that started coding in 1986.

By 1994, most people already had Turbo Pascal and C++ on Windows 3.x, I happen to have such boxes.

Turbo Pascal for Windows 1.5 and Turbo Pascal 7 both supported Windows 3.x.

Turbo C++ 3.1 onwards also did Windows 3.x.

Industrial use cases used purpose built OSes, and unstable piece of crap applies to all 8 and 16 bit home computer OSes without MMUs.

I'm down to just one unmatched expression, but it's going to require undoing many others to fix.

With so many wildcards (`.*`) involved, it feels as though making a few assumptions along the way is unavoidable. If I start over and only make moves I can prove are correct, I don't get very far.

Edit: Solved! :)

>At night you don’t see the tents, the tarps, the dirt; the whole of Burning Man resolves into a jewelled ribbon of lights and colour around you on all sides, studded with lasers and fireballs. Everyone else walking around is strung with colourful blinking lights; packs of cyclists with fairy lights spinning in their wheels, moving like shoals of luminescent fish. Cars and vans trundle around here essentially at random, made up to look like giant glowing worms, or deep-sea anglers, or spaceships, or colossal mining machines.

I've been going to TTITD for 15 years now; that sight is the magic that keeps me coming back.

Here's a recent article on the sub-industries that insure PV against hail, and predict and protect from hail:

https://reneweconomy.com.au/as-giant-hailstones-hit-the-suns...

Apparently in Australia climate change is making the hail bigger and more frequent.

You can't move the car protecting ones generally so it just comes down to making them tough and knowing your local weather, plus insurance.

Maybe the car insurance companies will cut you a check if you take the hit for them?

There's also a tight branding and trademark component.

I remember a major ad campaign when proper imported "Emmental" was rebranded as "Emmentaler" because the former name was becoming generic, and a related ad campaign about positioning and promoting Emmentaler as one of several kinds of "Swiss Cheese" along with Gruyere, Sbrinz and maybe a fourth one I don't recollect.

Oh I mean alternative would be a well regarded university/school in Germany or France... I'm French but we live in HK and most kids here (even the ones who go to the French International School or the German Swiss School) end up trying to go to UK or US universities. French and German international schools tend to not be that well ranked in the most well known rankings despite being very good technically (which is annoying when trying to get a visa to certain countries).

Part of my bias is that I was an exchange student at RIT and while I appreciated the experience, I was not impressed by the CS courses or the level of maths of the students going there.
Show HN: Open-Source and Free Chess Club Software
by whatamidoingyo | 2025-11-03 13:14:57+00:00
Hey everyone,

I recently started a local chess club. We had a few meetings already, and I've been winning a lot (heh). I thought it'd be a great idea to have the ability to keep track of games played, as well as give our members a local chess club rating.

I searched for open-source chess club management software, but couldn't find anything. It may be the case that it's just not something many people really look for or need, I guess.

It's still relatively new, I plan on implementing many more features and making it super easy to host. Let me know what you think! :)

Prior to western colonization of course the native people had conflicts, just not at the scale the colonizers could achieve. During the genocide of the natives some tribes used it as an excuse to kill their enemies, sometimes to curry favor with a technologically superior force, and sometimes just to kill their enemies. Some fought back against the invaders, with varying degrees of success. Most people just died.

None of that makes it less of a war against the native americans.

Some white-collar professionals enjoy continuing their work past retirement age. It can be stimulating, high-leverage, and I have often seen them contributing at key moments without spending much time at the office. The accumulated wisdom and political capital of many decades at the wheel makes a difference. I've also seen blue-collar workers keep at it past retirement age because of their finances or some other compulsion despite arthritis, weakness, bad sight etc and rue every moment. Let's make sure we understand that not every craft is heaven and not every corporation is a hellscape.

I understand the inconvenience to have to leave a keyboard-driven workflow but I think the Share button --> Copy link are common enough now that it shouldn't be an issue. I know firefox also has "Copy clean link" if you right-click on the urlbar.

I did not find an extension that does just that but it should be trivial to create one and assign a shortcut to it.
Show HN: Generate coherent, synthetic data at scale
by darshanime | 2025-11-03 13:16:00+00:00
Internally at our org, we have an ecosystem of over 200 microservices, implementing various parts of the business logic. To test any changes, we provide developers with on-demand sandboxed environments. One issue we had to solve for that was the creation of synthetic data across services, which respected the business rules and was coherent.

Today, we are happy to introduce datagen, a tool we developed internally to solve this problem. It generates coherent, synthetic data with the ability to model complex relationships. It is a new DSL (domain specific language) using which the user specifies the shape of the entity they wish to generate, and generator functions describing the logic for generating each field. The entity can be a table in a relational dbms, or a json document in a document store, or a csv file to upload on S3 etc.

The user writes models in .dg files that are transpiled to golang code, which can then be used to generate coherent, synthetic data.

Here is a simple example:

// users.dg model users { fields { name() string age() int } gens { func name() { return "Arthur Dent" // hardcoded value } func age() { return IntBetween(18, 65) } } }

Checkout the website for more information: https://ds-horizon.github.io/datagen/

*AI Model Support:*

Currently configured for Perplexity, Claude, and Groq (production-ready). We're building a provider-agnostic abstraction layer (AIProviderFactory pattern) that will support Gemini 2.5 Pro, Claude Sonnet 4.5, and others. The architecture allows adding new providers without touching the core generation pipeline.

*Why Perplexity + Claude + Groq today:* - Perplexity: Best instruction-following (98% vs 80% Groq) - critical for code generation - Groq: Fastest inference (cost-optimized), best for batch operations - Claude: Enterprise reliability, better for complex reasoning tasks

New providers (Gemini, OpenAI) are stubs - ready for activation when their APIs stabilize.

*Database Flexibility:*

We're backend-agnostic by design. Currently shipping PostgreSQL + MongoDB, but the persistence layer is abstracted:

- *Supported now*: PostgreSQL, MongoDB, Redis (caching) - *Planned*: Firebase Realtime/Firestore, Supabase, PlanetScale, Neon - *Coming*: DynamoDB, Datastore, Cosmos

Firebase support: We have adapters ready but haven't prioritized it because most enterprise customers need PostgreSQL compliance + audit logs. Firebase Firestore is on the roadmap for Q1.

*The key insight:* Our code generation doesn't depend on DB choice. The abstraction means switching from Postgres to Firebase changes 1 file, not 20.

Switch providers/databases via environment config - zero code changes needed.

If your perception of time is distorted in those last moments, perhaps you live another thousand or million years in what was your life in what was only a few seconds for the people watching you die. After this thousand or however many years you experienced, you are ready for the experience to be over.

Now what happens to people who are shot directly in the head with a gun? Or have their brain otherwise abruptly massively damaged.

Mid-air: yes. A boom with a charging cable or even beamed energy would be much easier.

On the ground: swapping batteries is faster, and batteries are cheaper than planes or drones. You want the expensive part back in the air as soon as possible so you don't need as many of them. On the whole this probably also simplifies logistics: in civilian aviation airport space is limited, in wartime it's easier to transport one hundred drones and two hundred battery packs to the frontline than to transport two hundred drones

I agree with R2 but KV is un-realiable. I said DNS but I meant CDN which R2 kind of falls into. Cloudflare is good in moving lots of data but most of their other products are not polished. It doesn't mean that they are not exceptional products. I have deployed a wasm-worker 5 years ago and it is still up and running to this day. I don't think a server would have survived or any other product from any other provider would have guaranteed such backward compatibility.

Seems to make sense, if Poolside is selling a product which requires (or strongly recommends) that Poolside customers have on-prem or private cloud compute capability in order to fully integrate all the tools, right now that compute need is likely going to be filled by using NVIDIA hardware. So even if NVIDIA isn't selling a ton of hardware directly to Poolside, NVIDIA is likely going to sell a whole bunch of hardware to businesses using Poolside's solutions.

As much as the whole AI thing feels like a bubble, this feels less round-trip-like to me than some of the other recent deals which have been in the press.

Hm. So what's the idea. All of FAANG, all investors, they all do it like that citibank person said, who failed catastrophically, because...? At best this tale reads to me: Even if you are fully aware, and super big, you are high risk of losing it all, and most people will lose it all. Is everyone who was involved in building these mega corps by investing smartly over fairly long periods of time now delusional, at the same time? We can see it, but they can't? Is that what's required to explain it?

I am not much of a trader, but I assume there are always insane opportunities to invest a few billion dollars in high risk/high gain stuff, no? Why wait for AI? You can try to time any market. What explains the enormous amount of money into this one?

AFAIK Safari was the first browser to support MathML fully, and FF also supports it. Chromium was the latest IIRC. MathML has been baseline-available since 2023 after Chromium got support.

The big issue is that MathML is designed as a target language, not something directly writable. So we still need a KaTeX equivalent, which compiles either LaTeX equations or other markup languages to MathML.

Regardless, the core issue that you have mentioned is now gone (or will be in a few years even if you want more availability).

There's plenty of real-world production use of TLA+, including by Amazon. The "toy model" approach may have limitations of a sort but it's far from purely academic - building simplified models of a complex system is routine practice.

The obvious difference with PowerPoint design is that non-trivial failure modes can be surfaced automatically if they're reflected in the toy model - PowerPoint slides don't do this.

You don't even have to use TLA itself for this purpose, a Lean development could also do this - but then you would have to put together much of the basic formalism (which ultimately works by combining the "modalities" of time, state and non-determinism) on your own.

Hi everyone, I've spent the last hours drafting a conceptual architecture for a new type of multi-agent AI network I call ASAN (Autopoietic Specialist-Agent Network).

It combines ideas like MoE, autopoiesis, QLoRA for 'rapid agent birth', and a governance layer. I've just put the full specification on GitHub (my first uplaode there) and would be incredibly grateful for feedback, criticism, and new ideas from this community. Thank you!

Oh, wow. 1) you're getting awfully defensive here. I didn't say there was some moral failing because Chinese shops distilled models from western ones. It's the smart play. I'm only commenting on how little of a moat first movers have. 2) if you can't admit that deepseek distilled their models from existing work I'm not sure what to tell you. The early models even identified themselves as chatGPT. It's widely known and has substantial evidence. This isn't team sports, you don't need to play defense. We deal with reality here.

For someone used to the typesetting quality of LaTeX, MathML leaves much to be desired. For example, if you check the default demo at https://mk12.github.io/web-math-demo/ you'll notice that the contour integral sign (∮) has an unusually large circle in the MathML rendering (with most default browser fonts) which is quite inconsistent with how contour integrals appear in print. It's not the fault of MathML of course since the symbol '∮' is rendered using the available fonts. It is not surprising that a glyph designed for 'normal' text sizes doesn't look good when it's simply scaled up to serve as a large integral symbol.

Even if we address this problem using custom web fonts, there are numerous other edge cases (spacing within subscripts and superscripts, sizing within subscripts within subscripts, etc.) that look odd in MathML. At that point, we might as well use full KaTeX. Granted, many of these issues are minor. If they don't bother you, MathML could be a good alternative. Unfortunately, for me, these inconsistencies do bother me, so I've been using MathJax, and more recently KaTeX, since they get you closer to the typesetting quality of LaTeX compared to MathML.

Modern America doesn't seem to have much of a culture of cheese.

I've just visited New Orleans, and the selection of cheese available in supermarkets was extremely limited. I recall the same issue from past visits elsewhere in the US. The fist time I visited I was horrified to see fake Bega cheese.

For more choice in New Orleans I would have needed to go to a cheese shop/restaurant chain called the St James Cheese Company (I didn't visit it).

I watched someone cooking a hamburger grab a slice of processed cheese (looked like a standard individual plastic packaged slice to me) and place it on top of the burger to melt (admittedly it turned out fine).

Oh, and all the milk I found in New Orleans was ultra-pasteurised (abominable taste) - I didn't see any standard/HTST pasteurized milk. Apparently shelflife is more important than taste. For comparison, Supermarket milk is pasteurized here in NZ (not ultra except for longlife tetrapack) and unpasteurized milk is available in Christchurch (not at supermarket, I think in a shop in St Martins or from dairy 30km out of Christchurch).

I admit that here in Christchurch for better imported cheeses I need to go to a cheesemonger. At my local supermarket today I didn't buy a yummy local aged gouda (Meyer) because it was USD40/kg : instead I bought 1 double-cream Brie (Mainland), 1 goatsmilk feta (Foodsnob - Bulgarian - cheap on special), and some "smoked flavour" processed cheese slices (Chesdale - plastic but I like it!).

For Emmentaler, the supermarket has "Swiss cheese" which isn't great. They have an imported brand from Germany Emborg Emmentaler Swiss Cheese block 200g NZD9.69 (USD12.7/lb) which you wouldn't buy for its flavour.

The Taliban was formed in 1994 and had very little to do with the Soviets. They became popular on a kind of 'tough on crime, say no to drugs' platform, because the US had invested heavily in local war lord drug barons and made a lot of money from drowning the world in the cheap heroin they provided.

If you squint a bit there's a suspicious cadence in the Taliban taking over and eradicating most of the heroin production and the US invading soon after and restarting it.

The Taliban also did messaging along the lines that it's not a good idea to use foreign investment for mining infrastructure and the like when kids are starving to death.

> 59kW/kg

At this point why don't we get rid of the k prefix and write 59W/g?

Edit:

I was half joking, but various answers mention kW being standard for motors, kg being the SI unit for mass etc. All true, but as used here in a combined unit, which means "power density" it still would make sense IMO. It's not like the "59" tells you that it's a strong motor and hence you want kW to compare it to other motors. You can't, it's just a ratio (power to weigth). W/g just reads much nicer in my head. Or we could come up with a name, like for other units. Let's call it "fainpul" (short fp) for example :)

59 fp is a new record for electric motors!

My meaning is that good URL design was more prevalent when people consciously included more links to other websites within their own website. This is because making well formed URLs is of importance if you think people are actually going to take that URL and link it somewhere. The rest of my comment is snark around SPAs, because I think they conversely do not often do URL design well (manipulating the DOM off the back of JSON REST API calls, rather than guiding the state of the page off the URL, allows one not to have to think about it as much as one should).

I hope that clears things up.

I think moving sidewalks could be more suitable for shorter distances than public transport or taxis. In many situations, it doesn’t make sense to order a taxi for a trip of less than 1,000 meters, or to walk to the nearest bus stop, then wait for the bus, just to travel a single stop. There are many people with disabilities who may struggle to walk these distances and would benefit from such an option. Additionally, moving sidewalks could reduce the time it takes to travel short distances within cities.

> What does this mean? What's the trick?

The trick is essentially to buyback your own shares and destroy them. That effectively redistributes the value you bought to other shareholders, much like a dividend would.

How is that better you may ask? two reasons:

- Most investors prefer to accumulate rather than receiving cash. If you post dividends, they are immediately subject to withholding tax, so you get taxed before reinvesting.

- In a lot of cases, capital gains tax and withholding tax are different, the former being much lower than the latter. This is especially the case for funds with foreign UBOs, which incur 2x15% WH tax at the source.

- Buybacks are just more flexible, those that want cash can sell, those who prefer to accumulate are happy to stay, there's no real downside.

I don't know about the Netherlands, but having spent a bit of time in Germany, you may be underestimating the mount of party planning that is ingrained into the various European cultures.

From an outside perspective, even fairly casual German gatherings feel like they are orchestrated with a level of precision that would do a military campaign proud - but the Germans I was with don't really seem to notice this (likely because they all already know their roles, and to them it's just part of their culture)
