Is there a mea culpa here? This was all clear for a decade during which you were "somewhat neutral on Trump" and everyone was telling those of us warning people about it that we were hysterical and deranged.

But now I see posts like this and it's like "how could we have known this was going to happen?". Well, you could have! At least maybe you can update your priors on how seriously to take warnings that a political movement is dangerous?

Weigh yourself every day. Journal it. This sets up an objective metric to calibrate against.

Set medium term goals. Don't try to lose 20 kilos in six months. Lose the next kilo by this time in two weeks. Similarly, don't try to lose 0.1 kilos by tomorrow. Weight naturally fluctuates day to day based on water intake, sodium intake, muscle fatigue, and other things. But in the range of 2-3 weeks, you should be able to lose enough weight to see signal in the noise of day to day fluctuations.

If you aren't hitting your medium term goals, find a way to cut calories more. Starting the first month doing a comprehensive calorie log is valuable to help calibrate what foods and portion sizes are relatively problematic.

The rest is just finding eating patterns that work for you that help keep calorie levels low enough. There's a lot of advice about ways to do that, and most need to be taken with a grain of salt, but it's probably true that you can min/max at the margins by increasing fiber intake, increasing protein intake, drinking more water, eating more raw plants, intermittent fasting, and that sort of thing. But you'll mostly see fractional improvements on top of the bottom line math: calories burned need to exceed calories consumed.

As noted elsewhere here, it's a lot of exercise to burn off a few pieces of bacon. Exercise is good for weight loss, but again, it's mostly at the margins for the average person, especially if that person is not an athlete.

Universities are not fast food restaurants, the reputation resides in the faculty, and they’re not replicable like fast food recipes or supply chains. “Harvard London” will be a completely different school with its own reputation (with a little bit of halo effect from the brand of course), just like no one mistakes UC Riverside for Berkeley. Unless you’re advocating for some remote teaching sort of deal.

Edit: In addition, some people only attend Harvard and co. for the networking opportunities.

Yeah, what you said is key - and I can also vouch that it's absolutely possible to keep it away for good, aside from small setbacks that almost everyone experiences, since we’re not robots.

The word diet is problematic because most people see it as something temporary. But you can't just eat healthy to lose weight and then go back to old habits, expecting the weight to stay off. That just doesn't make sense.

Also for many people, food isn’t just about pleasure - it’s also a way to deal with boredom, stress, depression, and so on. So even if someone sticks to a diet, if the psychological root causes are still there, it's going to be hard to stay away from junk food.

Relevant: https://github.com/Marthog/rust-stm which has usage instructions. It's memory safe as defined in Safe Rust, but unlike the Haskell implementation it's not "safe" in a correctness sense, because Rust does not afford the same control about mutability and purity. (At least, not yet - future additions to the language may improve this somewhat.)

It's easy to blame GoDaddy, but 'miscommunication' takes two.

You pay Markmonitor a shitload of money to make sure this doesn't happen. They should have dedicated people at GoDaddy and direct communication channels.

This is a significant fuckup on Markmonitor's part, even if GoDaddy did something different than was requested from them.

IMO cynical opinion, if anyone were to create a better tyre, that would save the consumer money, the company would be promptly bought and the product shelved for ever.

However, if someone invented a product that would result in the consumer needing to spend more money on 'safe' tyres or whatever, just watch the legislation and (artificial) public outcry demanding it.

>for one reason or another.

Exactly that. It was never that it straight-up didn't work. It was just that there was some issue.

I first encountered it with a TV that literally had a dead pixel. From there, the next 3-4 purchases featured something wrong. Monitor's built-in settings menu didn't display, cordless phone speaker issue, etc.

Dead pixels.

No way it was random. Funniest part was they'd get snippy with their return policy, like you were the problem.

Early 80's VMS had a Keep/Purge system for history of files. Everytime you edited a file a version number was bumped up by 1. There was a command, "purge", I think that set the Keep count which was default to 3.

This would have been within the contemporary Dos and disk capabilities and size of 160-360kBytes, although slow (5-15 seconds).

When Dave Cutler moved from DEC to MS I expected the Dos console under windows to get that same feature. Disappointed. A gajillion lost hours could have be saved.

> Major civil institutions of power and culture had been monopolised by the left; there had been a "default preference" for wealth over income, capital over labour.

I am not from the US, and I watch with mild amusement its slide into full blown banana republic dictatorship with a sprinkle of last century European fascism - I mean, at this point ICE is basically a secret police that disappears people, not unlike Stasi or Gestapo from years past.

But you thought that Trump was an answer to "wealth over income" or "capital over labor"? Even without knowing that much about the intricacies of US politics this sounds pretty naive.

> Chinese workers work longer hours more happily and they’re physically faster with their hands; they can do things that American labor can’t. It’s years of accumulated skill, but it’s also a culture that is oriented around hard work and education that the United States no longer has. In China, there are no people who are too fat to work. The workers don’t storm off midshift, never to return to their job. You don’t have people who insist on being paid in cash so that they can keep their disability payments, while they do acrobatics on the factory floor that the non-disabled workers cannot do.

he knows a lot about manufacturing but weirdly not much about labor. very unsubstantiated, derogatory comment.

it gets worse!

> Chinese workers are much less likely to physically attack each other and their manager. They don’t take 30 minute bathroom breaks on company time. They don’t often quit because their out-of-state mother of their children discovered their new job and now receives 60% of their wages as child support. They don’t disappear because they’ve gone on meth benders. And they don’t fall asleep on a box midshift because their pay from yesterday got converted into pills.

> And they can do their times tables. To manufacture, you need to be able to consistently and accurately multiply 7 times 9 and read in English, and a disturbingly large portion of the American workforce cannot do that.

>I can totally see that. Is it really that common in tech jobs

What is a "tech job"? Wouldn't a job where you are designing the electrical/mechanical/software parts of a car be a "tech job"?

Of course this is much more common in older, well established industries. But that is where most of the "tech jobs" are. Germany, especially labor laws, are hostile to start-ups so it is natural that people get employed at these older companies with union negotiated salaries.

> ISPs may as well offer 10gbps as a default

You're thinking with a technical mind, but don't forget the business, marketing, legal and support.

Why have "unlimited" speed as baseline while you can charge some 10 times more for the privilege?

Also don't forget that if you sell "10gbps internet" you might have to legally guarantee a percentage of that. Or you have to explain how networking works to everyone who complains they never see 10gbps on Speedtest.net.

Also the more you offer, the more expensive your modem has to be.

Hi HN,

We’re building Wetime AI, a travel-specific AI architecture designed to offer personalized recommendations at scale—without the pricing and opacity of generic LLM APIs.

The cost of using commercial LLMs (like OpenAI’s) for real-world applications—especially in verticals like travel—is a major barrier. Most APIs are priced per token, which becomes extremely expensive and hard to predict at scale.

So, we ran a comparative analysis of three approaches:

OpenAI API (gpt-4o-mini)

Self-hosted open-source (LLaMA 3.1 1B on AWS)

Our own specialized travel AI (Wetime)

Result: At 1 million requests/month:

OpenAI: ~$2,830

Wetime: ~$230–$410 → That’s a 10x–100x cost efficiency gain depending on complexity.

We’ve just received a grant from the Camino Network Foundation (a blockchain built for travel) to accelerate this infrastructure—making our architecture not just efficient, but also transparent and verifiable through on-chain data provenance.

We're going live with our Camino validator node this Friday and launching a Chrome extension for itinerary generation next. Curious to hear your thoughts—especially if you're building in vertical AI, travel tech, or decentralized data infra. AMA.

—Sietse CEO, Wetime AI

>Such protests are as much a signal to those who voted as it is to those who didn’t and those who hold power.

Non-voters is a good point but I'm not sure the affect with Trump. Are there people who weren't aware of how much people dislike him?

It is an ecosystem, like I get why it's happening but I disagree with the target.

>It’s no secret that dialysis is incredibly expensive. Each dialysis patient costs about $100,000 a year to treat, which means that Medicare spends over $30 billion a year treating ESRD patients.

>But have you ever really thought about what that means for individuals? The cost of dialysis is nearly 1% of the entire federal budget. Put into simpler terms, for every $100 Americans spend in taxes, approximately $1.00 goes toward paying for dialysis.

Might not be exactly 1% now, or it might be, since spending is now $6T per year. Regardless, healthcare due to being overweight/obese is a very large portion of government spend.

Remote education has a long and storied history from before the Internet: https://en.wikipedia.org/wiki/Open_University

However I believe they do require you to show up for _exams_. Online proctoring is a miserable disaster, especially in the AI era, so I think for credentials it's unfortunately necessary to have in-person exams. (edit: checked and they switched to online during COVID, unsuprisingly, but are considering switching back)

The ease of financial fraud is a separate issue. In the US I suspect that's linked to widespread identity fraud.

I always used to think negatively about people that were severely overweight (still do unconsciously if I'm being honest) as I always attributed their obesity to lack of will power. I'm a huge proponent of better living through chemistry (steroids - with frequent blood work, nootropics, whatever) and recently I decided to get my abs back. I hopped on some compounded semiglutide and was blown away by the change in my attitude towards food. I had always snacked at night after the kids went to bed and had built up about 25 pounds over the past decade. I was able to drop it all in 3 months without any sort of dieting, I just ate when I was hungry. Decided to not eat after 6:30pm and just did it, no issues while on the semiglutide.

Really changed my attitude about food, and my body and minds interaction with it. A lot of this is subconscious and really hard to get control of. The fact a chemical compound was able to change my mental relationship with food also put an interesting spin on my ideas about consciousness and self control as a whole. We are just slaves to our biological processes.

I dunno, Tramiel's Atari Corp kept the 8-bit line going for years after the changeover, adding new models. And they even had relative success later in places like Poland.

One problem is that these kinds of architectures that relied on special custom chips have inevitable obsolescence built in. When your "API" for graphics programming is a custom chipset at a certain clock rate with certain capabilities, it's just not going to scale up past a certain point. You get initial superpowers, but then Moore's law just makes it pointless.

I really wish this blew up more. I really don't think OpenAI (or any business, for that matter) should get away with releasing a technology with built-in behavior to deceive users using blatant lies, in order to look capable. Unfortunately, I'm afraid 98 % of people won't know and accept this as a step forward, which, for me, it is absolutely not.

> The issue is that of course Apple computers that are large enough to run VMs are… expensive.

Expensive compared to what? UTM uses Apple Virtualization Framework, which lets the guest VM only occupy as much memory as it's actually using (instead of reserving all of its available memory). This means it's viable to run a Linux VM on e.g. an 8GB RAM MacBook Air.

Well the tarrifs do very much show that Trump has no "default preference" for the capitalised class -- he's very willing to wreck the american stock market.

Whether his solution works or not isnt relevant to whether Trump's real preferences aren't, "by default", the american corporate owner.

It's very unhelpful to reduce trump down to basic evil motivations, and to call any ascription of a non-evil one, "naive". It has been this manner which has made the left entirely unable to communicate beyond its self.

> Commercial produce today is both less flavorful and markedly less nutritious than what our great-grandparents ate. Outside a home garden or a farmer’s market, the modern consumer can’t taste truly fresh produce. In our pursuit of endless abundance, Twilley explains, we have lost “diversity and deliciousness.”

Yup. Turns out, the varieties that do best in climate controlled greenhouses aren't the ones that have much going on in terms of flavor.

Thankfully at least in Germany there still are farmers' markets, and in Croatia any small town will have a daily one - and the difference is night and day, even compared to German farmers.

I've known two people who went to clown school and they both have just incredible comportment & composure. Extremely self-assured, naturally using subtle aspects of positioning and body language to make people comfortable, draw others into conversation and reassure them that their participation is valued.

They both have clearly playful senses of humor once you get to know them, and a lot of surprising little physical, verbal, and musical skills. But neither has that, ahem, "class clown" center of attention type personality. They're just confident, socially skilled, well liked people, one of them is one of the most effective managers I've ever known.

It's long made me wonder what they teach at clown school. When I was reading through this list, thinking of these two, I kept going "ahhh I see." Maybe they were like this before the school, probably were to some extent. But it's also kind of foolish to think several years of focused study on how you can use your body to affect people's perception of your actions would bear no fruit.

The problem with diets based only on calories is that they don't take satiety into account, nor health.

Calories is what makes you gain/lose weight, it's basic physics. Satiety is what makes you want to eat more/less. Nutrients are what is making you healthy.

Fiber and protein tends to make you feel full. Lack of them allow you to eat large amount of calories without feeling full. You need to keep track of micro and macro nutrient to stay healthy.

This planet is 2.6x larger than Earth and has concentrations of DMS "thousands of times stronger than the levels on Earth".

It would take a lot of cometary impacts to seed the entire ocean with that much.

From the paper [1]:

> Therefore, sustaining DMS and/or DMDS at over 10–1000 ppm concentrations in a steady state in the atmosphere of K2-18 b would be implausible without a significant biogenic flux. Moreover, the abiotic photochemical production of DMS in the above experiments requires an even greater abundance of H2S as the ultimate source of sulfur—a molecule that we do not detect

Show HN: Image Aspect Ratio Calculator
by ishjoh | 2025-04-17 12:33:14+00:00
Hi Everyone,

I vibe coded an image aspect ratio calculator and wanted to share it because so many online tools are cluttered with ads and I hated that experience.

I find myself having to often get the image aspect ratio for an image and then calculate which standard aspect ratio it is similar to and then crop the image to match. So I've made a tool that does that in a single step.

The best part of all, it runs 100% in the browser, your image is never uploaded to the server so even for copyrighted work you can use this tool.

Let me know if you like it or how you think I can improve it.

> At what point can we say that the US truly has fallen from being the leader of the world?

It's easy to talk about the "decline" of the U.S. in abstract geopolitical terms, but let's be honest: the day the global tech community stops posting on Hacker News, stops building with U.S origin technologies, and stops looking to Silicon Valley as a benchmark, that's the day we can seriously start talking about America's fall from global leadership.

Until then, we're all still running our infrastructure on AWS, building apps with React, debating threads on HN, and watching YC Demo Day like it's the Super Bowl. The world may grumble, but it's still plugged in, literally and figuratively, to American innovation.

Yep, vaporwave is very millennial-centric, with song samples rooted in '80s and '90s pop, with an intentional pre-Internet feel. Things that millennials would have fading, but extremely resonant, nostalgic memories about.

The younger generation caught on to vaporwave's appealing use of slowed and reverbed samples, and created their their own spin on it now with "Frutiger Aero", which is 2000s vaporwave with a graphical/audio aesthetic that brings to mind Windows XP/Vista, Nintendo DS/Wii, Neopets, Flash games and early Youtube but cuts off before the iPhone age.

I’n about to embark on my first Apple Silicon machine tomorrow, and UTM is a core part of my plans for it. The difference from TFA, for me, is that I already have some mature Nix flakes for doing development in WSL that I’ve built up over the last year. If I can’t have that environment bake a VM for me wholesale, it’s probably a short `nixos-rebuild switch --flake` away.

Have you ever struggled with sharing Full Stack Application components across projects? Or found yourself copying and pasting code repeatedly? If you've said yes to this, you're not alone. These are exactly the problems that led me to explore Bit.

Bit is a platform for building applications using independent, reusable components. Unlike traditional approaches where components are secondary to your application, Bit puts components at the center of development. This creates a more modular, maintainable, and collaborative way to build software.

We do not assume a status quo or equilibrium, which will hopefully be clear upon reading the paper. That's not what normal technology means.

Part II of the paper describes one vision of what a world with advanced AI might look like, and it is quite different from the current world.

We also say in the introduction:

"The world we describe in Part II is one in which AI is far more advanced than it is today. We are not claiming that AI progress—or human progress—will stop at that point. What comes after it? We do not know. Consider this analogy: At the dawn of the first Industrial Revolution, it would have been useful to try to think about what an industrial world would look like and how to prepare for it, but it would have been futile to try to predict electricity or computers. Our exercise here is similar. Since we reject “fast takeoff” scenarios, we do not see it as necessary or useful to envision a world further ahead than we have attempted to. If and when the scenario we describe in Part II materializes, we will be able to better anticipate and prepare for whatever comes next."
