It’s not hard to tell at all.

At peak season every year, O’Leary says something crazy like they are going to charge for the bathroom, or charge fat people extra, or get rid of arm rests, or have standing room only. The tabloids run the story, and always mention how cheap the flights are, including whatever the cheapest deal at the moment is.

It’s very, very obvious advertising. The tabloids go along with it because it makes people angry, which drives traffic.

For the past two months,

With some friends, I've been building "Mo Money": a Duolingo-style app to teach investing through a gamified mix of microlearning and a real-time trading simulator (but it's a game). It's meant to be built as much for total beginners as it is for amateurs.

Sim side: A fully playable trading game backed by historical market data (no real $$), it's now integrated with a FastAPI backend, WebSockets, Firebase (soon), and XP system to track skill growth and gamify progress.

Learning side: A clean microlearning stack that teaches financial literacy in snack-sized bits, a lot like Duolingo, it's interactive, level-based & accurate and relevant information in the most digestible format.

Just added: a lightweight AI tutor for contextual Q&A during lessons. Thinking of adding a little more AI than a chatbot potentially to help learners in the app.

Upcoming: XP-linked achievements, a leaderboard, and a light paywall via Buy Me a Coffee.

We're undergrads building this from scratch, aiming for early users soon. If you’ve ever thought “I wish someone made markets feel learnable,” we’re trying to do just that. super excited

People should get on the bike and start cycling for real (like burn 200W an hour). Their perception of glucose will flip 100%. Suddenly glucose is like the fuel to your body, that you can't cram enough into. Which means white bread in the morning, croissants (and coca cola with sugar) will be your friends. Quite frankly a much better lifestyle.

> The poorest American state, Mississippi, is richer per-capita than most European countries, including France.

The state, maybe. The missisipian, not so much - considering their Human Development Index is right in between that of Hungary and Bulgaria, at the very bottom of the EU. How great is it to be able to buy expansive cars if you can't get access to education, healthcare, retirement, and will find yourself in the street if you lose your job.

VAG cars are weird, I've had both an Audi A1 and a VW Up (short lease for work); they are basically the same car, both had a 3 cylinder, 1 liter engine, similar interiors, etc. But the A1 had the sports look package and generally a fancier feel to it. But VAG uses the same base for a lot of models and brands (VW, Audi, Skoda, SEAT); quality wise there's not much difference between them, but price wise they are, with Skoda being the 'budget' brand and Audi the premium. They also own Porsche but I don't know if they use the same base, I presume not... even though with the amount of Cayennes you see on the road here they sell Porsches at similar rates as upmarket VW / Audi cars.

They may be a small part of the economy as measured in imaginary numbers being shifted around but still have a significant negative effect on our lives that cannot be easily escaped. This is even more true when you also count publicly traded companies which have similar incentives to sell out their "customers" in order to benefit the real customers and are often just the final form of VC funded startups.

It was a funny experience going to buy a used car with my partner a few years ago. Being a little naive I'd assumed being a cash buyer was a plus as they'd guarantee a quick sale, but as soon as the salesman realised he wasn't going to be signing a finance deal you could see him lose interest entirely. kinda funny to think they're in the business of selling loans rather than cars.

LLMs made things a lot easier but before them I wished there was a stackoverflow but paid, so you could pay someone for an answer if they happened to have specific information.

You could kind of emulate it by buying stackoverflow upvotes, then placing that as a bounty. Its not exactly money but it made it more comfortable (and successful) than hoping someone answers for free.

And with the introduction of ETCS the number of trains can theoretically be increased even more, as the distance for safe operation between the trains can be reduced thanks to it. I agree on all points though: the German Railway is in a predicted crisis and has very little to do with problems inside DB itself but from regulations stemming from the owners (the German Government). Without money to invest in new infrastructure and its maintenance nothing can get better, no matter what DB does.

Sure, if you don't trust anything what's the point. There's a lot of information that relies on anonymous sources and we usually use third party to vet them (otherwise how would they stay anonymous). Without this system we'd be missing out on a lot of things (if only named sources are used, a lot of things would never come out).

(A lot of things break down in society without trust, maybe that's already how the US is? Where I live it is thankfully still somewhat ok)

White bread has a bad carbohydrates per protein ratio, but nonetheless it has a much higher protein content than almost any other cereal (i.e. except oats) and a much higher protein content than anything else with a comparable price.

So saying that it is basically 100% carbs is definitely wrong. Good wheat flour for bread has about 1/8 of its weight as proteins, while e.g. maize meal has only about 1/16 and rice between 1/16 and 1/12, but typically towards the lower end of that interval.

White bread is the cheapest source of proteins, but it has the serious disadvantages that its proteins are digested incompletely by most people and the proteins come with too much carbohydrates. The carbohydrates, i.e. the starch, can be removed totally or partially by making a dough and washing it, but that consumes a lot of water and time.

Otherwise, I agree with what you have said.

White bread could be combined with something that contains mostly proteins, possibly with fat, e.g. chicken breast or eggs, but then bread retains no advantages from its higher protein content (except of lowering the total cost of the food), so it should better be replaced by a healthier source of carbohydrates, i.e. maize or rice.

Note that what was being claimed was that “Apple is basically a smartphone company at this point, and smartphone sales are plummeting”. Whether iPhone sales are growing, bounced around a bit, or have plateaued is irrelevant. It’s pretty clear they are not plummeting.

This part is still misleading: "The ICE test train used was a Velaro Novo test car from Siemens Mobility"

The test train used is a set from the late 20th century. So old that its regular brethren are already scheduled for retirement. This is the last generation of ICE that was still using separate locomotives (and with that, limited traction) instead of powered wheelsets distributed all over the full length of the train. The only thing Velaro Novo in this demonstration is that they inserted an unpowered prototype car into the trainset.

Certificates are still a pain in the butt. One of the most cumbersome aspects of the web.

Especially domain wide certs which need DNS auth.

DNS auth would be okish if it was simply tied to a txt entry in the DNS and valid as long as the txt entry is there. Why does LetsEncrypt expire the cert while the acme DNS entry is still there? Which attack vector does this prevent?

Also, why not support file based auth in .well-known/acme-challenge/... for domain wide certs? Which attack vector does that prevent?

Nowhere. Does that make LLMs nondeterministic?

Did you read the blogpost in the OP?

I cannot understand what I wrote for you on your behalf. What could possibly be unclear about this? Or was this another rhetorical like the previous one, to polish your snark?

Yes, I was. Are you able to ask non-rhetorical questions too? Should I have asked for your blessed permission to write more than just a direct address of what you asked about?

Important topic but is expected behavior (questionable research if implying this is something that happened randomly):

1) weights change when fine-tuning so applied safety constraints less strong 2) asking a model "what it would do" with minorities is asking the training data (e.g. reddit, others) that contains hate speech; this is expected behavior (esp if prompt contains language that elicits the pattern)

I think there are two major problems with those lesser-known spots:

1. Discoverability, which is going to be majorly affected by LLMs. On one hand they already feed on preexisting corpus of recommendations, naturally biased towards the popular pots, on the other hand part of business model is bound to be "sell biases", therefore better known spots are going to be at an even higher disadvantage. Even if you do try to go out of the beaten path for e.g. wine tastings, information regarding those is going to again be biased towards the ones selling mediocre wines with an overpriced "we ship a box to your country, just give us an address" service.

2. Reachability. Suppose you want to visit the relatively famous Gelateria Dondoli at San Gimignano. Starting at Florence using public transport it's IIRC two transfers with a transport mode change! If your goal is any agriturismo-style spot - car is the only reasonable option. Spending a bunch of time traveling already limits tourism opportunities, doing that by car is definitely not for everyone as you are effectively limited to enjoying wines at home. This dynamic naturally biases towards larger spots, covering variety of touristic needs.

Author notes that there is still a standing offer to answer questions for free "if time allows" but doesn't get any inquiries. I believe this shows that it isn't due to fame or the payment making the author seem more legitimate.

Instead I think that the payment creates the expectation that the inquiry will be answered and when someone expects an answer they are more willing to inquire. When the consultation is free or "time permitting", then it might simply be refused but making the inquiry itself isn't zero cost for the individual and their mental calculus makes it not worth asking. The mental calculus is, "What is the person getting out of this interaction and why would they choose to answer me but not someone else?" When it is financial you can see that you are equal to everyone else and you see exactly what the consultant is getting out of it.

There are cheaper European cars than VW (and why compare with their 'average mid-range offering'?).

The new (and widely liked) Renault 5 EV starts at around €21K, for instance. Probably a bit smaller than something made in China for the same money, but not worlds apart. https://www.renault.fr/vehicules-electriques/r5-e-tech-elect...

> Every part of the house depreciates without maintenance. At some point the house will depreciate and the lot will be worth less than it would be if the house was already demolished.

That really depends on the market. There are areas near me where property prices have increased so rapidly they outpace any losses from depreciation. Not necessarily a good thing of course as it does lead to very expensive houses and difficulty with people trying to buy their first house.

There is story from the early 1980’s that is illustrative. During the building of Trump Tower, the future U.S. president had massive trees brought from Florida at great expense and planted in the atrium. He decided he didn’t like the look after all, so he called for their removal. When it couldn’t be done in 24 hours, he had the trees chainsawed to pieces.

It turns out that capriciousness may not scale well though.

Wow, 20% of manufacturing employees across the whole business, too?

> ... as CEO Lip-Bu Tan downsizes the company to match its falling sales and weak outlook.

Given the lack of progress on intel's core CPU offerings, I'm not surprised. I recently used a 2017 8700K while my 2025 PC was in for repair and there was no noticeable difference between them. Nearly a decade and many days I forgot I was on the old machine!

I believe an intel fab in the US was making 486 series processors still until mid-pandemic for industrial and automotive use.
Show HN: Oomol – A local-first, code-first workflow automation engine
by monica-guli | 2025-06-30 08:40:08+00:00
Hi HN,

We’ve been working on [OOMOL](https://oomol.com) for the past few years – a workflow automation platform built for developers.

Unlike Zapier or n8n, OOMOL runs locally in a containerized environment, supports full Python and Node.js (with third-party libraries), and gives you the same flexibility as writing real code. It’s like VS Code meets workflow automation.

Key points: - Local-first (no cloud lock-in) - Python and Node.js support (you can mix both!) - Pip/npm libraries supported out of the box - Fully visual with programmable nodes - Share & reuse flows as containers or subflows

We’re still early, and would love feedback from the HN community. Happy to answer anything!

There's a number of good reasons not to make everyone run a kernel level anti-cheat. Linux (and therefore SteamOS) compatibility is a big one.

I think the status quo where anyone on any platform can access the vanilla game -- where cheaters may not even be a huge problem depending on one's skill rating -- and the most competitively-minded players have the choice to play on FACEIT, works pretty fine.

I do wonder what the 90% of built-in game content you're referring to actually is.

It's a tradeoff. When you have a "flat" union like `A | B | C` that makes it easy to pattern-match "leaf" errors, you give up the ability to add any additional context in function1 and function2. Although, there are workarounds like

struct Error { leaf_error: A | B | C, context: Vec<String>, }

> It is like me claiming the land of any country

Im not talking about claiming land - I’m talking about culture, racial identity and their heritage to lands. You keep bringing this as a talking point, but I already said heritage does not equate to or justify nationalism.

> Heritage that is so remote that it doesn't matter anymore. Most of their ancestors left centuries ago.

It doesn't matter? Obviously it does matter. I wonder if you think the same of African Americans and your willingness to deny them of African heritage.

What about eastern european Jews that actually look semitic, that have middle eastern features? Do you also negate them of heritage, or just white skinned Jews?

Your bias is palpable.

There is a distinct difference in quality of ride in ICE trains when compared to RE trains:

- For some reason, the luggage compartments in many regional RE commuter trains are an example of drug induced circus design. People can not fit larger commuter bags in there

- The seating is less comfortable

- ICE trains have priority in terms of railway usage

- The passenger group is more friendly and respectful on the ICE trains

- Great restaurant service

- ICE are faster. I can travel in 1h from Frankfurt to Cologne.

If you need the configuration for work (speed of travel, working space), then ICEs are clearly superior and worth the cost. I cringe every time I have to get into RE trains. Not because I can not handle it, I am well travelled, but because I know what I can in the other trains.

(Full Disclaimer: I spend a lot of money for the BC100 every year. It is an essential component of my life).

Certificates have a static expiry date by design - it's not "LetsEncrypt expiring the cert". There is no way to avoid expiring a cert if the DNS entry is still there - all you can do is make it easier to renew the cert. That means it must be automated, in which case it doesn't matter if you need to re-create a DNS entry.

In my experience, it takes a little effort to set things up the first time, but from then on it just works.

CGMs are a great but if you wish to lose weight you have to create a calorie deficit as opposed to a surplus harder to do in our carbs heavy, sugar loaded, ultra processed foods dominated diets which are extremely unhealthy for us.

I know I went from a 7.1 A1C(type 2 diabetes) to a 5.3 A1C(no diabetes) in a little over a month by going on a Keto diet while laying off the carbs and exercising regularly. If you don't CGM or not you'll end up like the almost 1/3 of the US population or 98 million Americans who are currently pre diabetic looking to join the 38.4 million who are already full blown diabetics a condition often called the silent killer for good reason (heart disease, stroke, chronic inflammation, kidney disease, nerve damage, and vision loss). Chronic inflammation also thought to have a direct link with cancer

Yep. I think SEAT are the pick of the VAG brands. Their marketing isn't about being cheap, but they're aimed at the youngest market segment, who also have the least money, so in my experience have the best prices.

Pre-COVID we got a new Leon ST — essentially a Golf estate/station wagon — for about a third off the list price: £13K instead of £20K (I know: those prices sound semi-mythical now).

On the other end you have Audi, whose premise seems to be: "So you want a VW, but you want to pay hugely over the odds for it? Certainly sir, step right this way."

no doubt its fashionable to think "perl == line noise == bad"

however, there are certain sub languages (slangs) where the use of punctuation chars as operators is very helpful, of course regex is the most compelling where the code is parsing one char at a time

my regex url { ^ # Start of line [<http> s? '://'] # Match http or https ['www.' ]? # Optional www. [<[\w\-]>+ '.' ]+ # One or more domain segments <[a..z]> ** 2..6 # TLD, 2 to 6 lowercase letters [ '/' <[\w\-./?%&=]>* ]? # Optional path/query $ # End of line }

imo raku has improved the situation a lot by introducing "regex 2.0" with deep support for unicode and with built in grammars that can work smoothly with regex

The https://www.youtube.com/watch?v=CCFfibo9uR4 has interesting discussion about how FADEC had a bug in 2019 [https://avherald.com/h?article=4c2fe53a] and only five years later in 2024 [https://www.federalregister.gov/d/2024-21144/p-13] quote: The NPRM was prompted by incidents related to erroneous A/T behavior during a balked landing with the A/T engaged (FADEC), potential erroneous readings from the LRRA(radar altimeter), and possible deficiencies in low airspeed protections and crew alerting systems.

The only known fact is that both engines had shut down simultaneously, as confirmed by the Civil Aviation Minister. This either means a fuel problem or a software glitch; FADEC will not allow pilots to shut down engines in flight, but it has authority to do that on it's own.

Speculation: So you have a low-flying plane with electrical issues (blinking lights were reported by the survivor); it loses power after takeoff (survivor reported “plane hung in air”). RAM deploys and FADEC gets readings that are near the ground, it commands engine shutdown.

On Jun 29th 2025 India's Civil Aviation Minister said: "It has never happened that both engines shut down together." Investigators are analyzing the black boxes from every angle including engine issues, fuel supply problem or something else including sabotage. A preliminary report is to be expected in three months.

After 10 years in defense tech, watching missile attacks in Ukraine and the Middle East made it clear how little most people really get about air defense. So I'm builiding this simulator which drops you into the operator’s seat. You can test out different scenarios and build an air defense network against various types of threats (stats from real world). Also have Ukraine, Israel-Iran scenarios.

The point is how much non-vision sensors vs pure vision, helps humans to be humans. Don't you think this point was proven by LLMs already that generalizability doesn't come from multi-modality but by scaling a single modality itself? And jepa is for sure designed to do a better job at that than an LLM. So no doubt about raw scaling + RL boost will kick-in highly predictable & specific robotic movements.

Many alternatives (like Doodle) are full of ads, which makes their products unusable. My goal is to try and make the internet a little better place by offering a free version without ads.

Currently rethinking what a scheduling platform should look like in 2025, perhaps with AI integration to ease the planning process.
