An electron is more flexible in its internal structure than a soap bubble so BLP claims it does all possible great circle orbits all at once. The charge distribution does not change over time so there is no radiating away of energy even though the charge is all moving and orbiting. There are a bunch of spreadsheets calculating Helium states on the Atomic Theory page. https://brilliantlightpower.com/atomic-theory/ has a table of contents that includes Excited States Of Helium in chapter 9 page 301.

A human artist puts in work and passion to create beautiful art from almost nothing. It brings them joy that their art brings someone joy. Every art piece has a story behind it, sharing their art with others gives them motivations to not only continue doing it and bless the world with more art but it also gives them feedback that yes this art is liked by someone out there. This feedback loop is part of what creates healthy civilizations.

For casual human use I would say Fahrenheit is one of the more easily defended imperial units since it has more resolution.

In reality hearing its 80 outside where I live could mean beautiful day or sweltering mugginess so it's never been a great indicator for me regardless of unit.

Or when people adjust a thermostat by like 2 degrees. If you changed it and didn't tell me idk if I would even perceive it. Temperature is weird.

Whether I like this feature or not depends on the low-level details of how @pool behaves and whether and how I can control it. I can't tell what @pool is going to do to my program, unlike when I'm using an arena (or another allocator) directly.

It seems that @pool is providing context the the allocator function(s), but is the memory in the pool contiguous? What is the initial capacity of the pool? What happens when the pool needs to grow?

I think I prefer the explicit allocator passing in Zig. I don't need to ask these questions because I'm choosing and passing the allocator myself.

I recommend Examine.com for supplement literature reviews which are far more in-depth than Wikipedia.

"Research indicates that American ginseng may improve short-term working memory and reaction time, particularly at lower doses, and some positive results were noted in older adults and people with schizophrenia. However, the overall effectiveness on cognition remains uncertain because no significant improvements were found in verbal memory or attention."

Wouldn't it be possible to float teflon balloons (without ever descending to the surface), and use those to carry a launch platform? Samples do not need to be surface samples, the atmosphere itself seems quite interesting already.

And note that you may be able to "fish" for samples from an atmospheric floating platform; there is no specific need to get all the way down to the rocks with your rocket.

Yes, I think it will be taking place for the remainder of our lifetimes.

Solar growth is likely to remain exponential for the next decade or so, which will create a number of new opportunities. Other energy sources will also come online. But fossil fuels are unlikely to be regulated away, globally. We are also likely past some serious tipping points— so I prefer to figure out ASAP whether stratospheric aerosol injections are a viable tactic for preventing the melting of permafrost, for instance.

Responding narrowly:

ripgrep doesn't do "terminal syntax highlighting." It has some basic support for colors, similar to GNU grep.

GNU grep and ripgrep share a lot of similarities, even beyond superficial ones. There are also some major differences. But I've always said that the venn diagram of GNU grep and ripgrep has a much bigger surface area in their intersection than the area of their symmetric difference.

Very wrong analogy. Anxiety is not something that you gain by buying junkfood due to low budget or laziness or simply being raised with very wrong values re food and health. On the other hand, every single ice cream, pizza, burger with fries, cupcake or beer contributing to resulting weight is a voluntary choice (with some mental drama around).

There is simply no way around the simple fact that there is only 1 way to eating well long term - that is lesser, more healthy portions. GLP1 may show a person what things could and should look like, what is achievable but the path needs to be walked by themselves. The alternative is either lifelong consumption of this chemical with various bad side effects or premature death (or both, to be seen since nobody has a clue).

Severe limitations? You sound like an a*hole tbf. The tool clearly provides the value, and it's a magnificent display how something like a simple LLM can be used to make your everyday life easier without compromising other minor stuff, you know, like letting other companies make profits by selling your own data?

Perhaps you live under a rock, I don't really know, but it maybe just happens that you're not a target audience? There's for sure many folks, and even more so companies, who will value their own privacy more over practice vs practise bikeshedding.

i recommend this paper to understand brain-state-in-a-box[0]. In my studies of linear algebra / calculus, we had optimum calculus reaching error minimum.

help me out, i learnt it a long time ago, would "Optimum in der Infinitesimalrechnung" be optimum calculus?

Assembly is one of those things where setting your ambitions higher than is usually advised can be wise.

You could try writing a game (perhaps using Raylib) or a pixel art editor. Or maybe a little web application for your Homelab.

Simple C libraries (Raylib, libcurl, early win32 APIs) tend to be dead simple to use from assembly.

Most asm tutorials are either bare metal / OS or “we will talk directly to the kernel”, but there’s no reason you can’t interface with higher level libraries and make real apps and games. It’s simpler than it sounds because a whole lot of your code will just be moving things around between registers and memory in order to make function calls and bookkeep your program state.

Let me paste the introduction in the post, and let's see how much it claims that C3 has memory safety:

Modern languages offer a variety of techniques to help with dynamic memory management, each one a different tradeoff in terms of performance, control and complexity. In this post we’ll look at an old idea, memory allocation regions or arenas, implemented via the C3 Temp allocator, which is the new default for C3.

The Temp allocator combines the ease of use of garbage collection with C3’s unique features to give a simple and (semi)-automated solution within a manual memory management language. The Temp allocator helps you avoid memory leaks, improve performance, and simplify code compared to traditional approaches.

Memory allocations come in two broad types stack allocations which are compact, efficient and automatic and heap allocations which are much larger and have customisable organisation. Custom organisation allows both innovation and footguns in equal measure, let’s explore those.

It's funny how many people still think sloppy, mistake-filled writing is a sign of AI, as if their writing is at the same level as the image generators giving people six fingers, when the truth is the current LLMs use better English grammar than 99% of humans. Their writing may be kind of boring and standard, but they don't confuse "their" and "there."

I'm your typical HN, tecchie, paranoid, privacy-obssessed "don't track me" nerd.

But I have absolutely no problem with haute cuisine restaurants doing this.

There's a few reasons that make this special, and in a completely different universe than being tracked online.

1. Most people, my wife and I included, seldom go to haute cuisine restaurants. When we do, it is a very special, once in a lifetime experience.

2. Restaurants are not staffed by hackers and advertising engineers. They are going to start with opt-in questionnaires that you will fill out when you make your reservation. That questionnaire will often come in one of two forms: a) they will just ask you verbally when you phone or b) they'll send you a package when you make your reservation. That package is usually pretty special unto itself. It's going to feel like a welcome package, and they are going to invite you to share anything that you think is helpful, entirely voluntarily. Typically they'll ask about food preferences and dietary restrictions... but I mean, they'll get a lot just by giving you a text field that asks "Are you celebrating a special occasion, or anything else you want to share?" You're free to put whatever you want in there, and leave anything else out.

3. Now we get to the social media part. This is doing a little bit extra above what most haute cuisines have done in the past. But remember - they can only find what you make public. They're not like, DM'ing people on your friends' lists etc. or hiring a private investigator to stalk you.

Once you're in the door, the idea of remembering that you were there before and jotting down your preferences etc. so that if you return they can make you feel even that more special... this isn't McDonald's, or even a fancy steak house, that we're talking about. This is a place that most people - if they go at all - are going to go ONCE. So people who return are extremely special and to show them that level of "we give a fuck about you" is what sets these restaurants apart.

One experience that my wife and I had was at Victoria & Albert's at Disney's Grand Floridian resort. We spent $2,000 on that meal. Why? Because it was our belated honeymoon. We were highschool sweethearts, got married and had kids really young and were extremely poor for most of our marriage... so we saved up and it was once in a lifetime. For that money... this level of service is a huge part of how they go above and beyond to make their patrons feel like it's worth it. If most people felt freaked out by it, that some personal boundary was being crossed ... it would be the last thing they do. But they realize that your typical dining experience is pretty impersonal. That if you're going to shell out that much money on a dinner... it needs to be more than just the world's best food.

> Forget Celery

How do you do background job processing without Celery? Every app/website I ever developed required some sort of background job processing, for Python I use Celery, Rails I use Sidekiq, Node.js I use Faktory. One of the biggest drawbacks (at least until a while ago) was that setting this up had to be a hacky webhook call to your own app that allowed up to N seconds request/response.

In every North American city facing rising housing costs, there is a literal ocean of usable, desirable land for housing, already serviced by municipal infrastructure.

And every month, a percentage of that useable and desirable land comes up for sale, meaning it’s previous owner occupiers are voluntarily moving, and a new owner, if they chose, could redeploy the land in a way that provides homes to many more people, while not evicting anyone.

Unfortunately, each of these cities has also made it illegal for this transition to happen, mandating that the only way you’re allowed to build larger buildings, (if at all) is by demolishing another large (and occupied) building first.

We should change that!
by kjellsbells | 2025-07-14 13:38:32+00:00
I'm going to sound like a grinch here, but the flip side of researching the guests to provide stellar service is that the people who don't show up in the persons of note list may end up getting crappier service. It's like the notorious practice of fashion people not qualifying to buy an overpriced handbag until they've proven their loyalty to the brand by buying previous overpriced handbags.

The reason people come back from overseas trips raving about some cute little trattoria or izakaya joint is rarely because the owner sponsored a penguin, but more because the host achieved a genuinely human connection with the diner.

Atmospheric sample retrieval—not from the surface—seems doable.

> "90x Earth's atmospheric pressure and 450°C" — becomes Earth-like conditions at higher altitude

> "while sulfuric acid clouds would rapidly degrade balloon materials" — Teflon coatings are a solved problem; JPL did coupon tests[0]

> "The energy requirements for escape velocity from Venus are also substantially higher than Mars" — True, but you'd only need to launch a tiny, dumb payload into orbit, to rendezvous with the return craft. Like Apollo, sample returns aren't one monolithic spacecraft that does the full round-trip; think the Apollo Lunar Ascent Module, but, for ants

[0] https://sci-hub.se/10.1016/j.asr.2007.03.017 ("Prototype design and testing of a Venus long duration, high altitude balloon")

> "Although the expected sulfuric acid concentration at Venus is expected to be in the range of 75–85%, tests were conducted up to 96% to understand our design margin. The material itself was found to be unaffected by prolonged exposure to all concentrations of sulfuric acid up to a temperature of 70 °C. Adhesively taped seam samples did show some discoloration at the tape edges, but there was no evidence of acid penetration into the joint using blotter paper on the inside surface. This test confirmed that the cover tape adhesive was indeed resistant to sulfuric acid as predicted and can support a long duration balloon mission at Venus."

edit: I totally forgot—the Soviets already demonstrated that, in the 70's:

Dreams of Flesh and Sand by William T. Quick reads like a rip-off of Neuromancer ... and it should be bad ... but I really like the writing style and the characterisation -- Berg, Toshi and Calley seem pretty cool and real, and so it may be a rip-off, but it feels like a fun and interesting rip-off. Worth a look.

Void Star by Zachery Mason is also good.

Ads are automated, no human involved into the actual research of a specific visitor. It's still creepy, but less personal. Some people can accept this line. But I also guess, with AI this line might be moved again.

The deeper reason is probably, machines are following rules, and they do it equally, focus on their specific job, without any hidden agenda. Humans are different, they have personal opinions and their own agenda, they can even be abusive. This is taking control from the people, and many people don't like losing control.
by ohadpr | 2025-07-14 13:40:49+00:00
honestly, kind of both. it started as a curiosity. I just wanted to see if it could even work. but after playing with it, I think there’s something deeper.

the most interesting part to me is the idea of apps that self-customize without being told to. they adapt based on how you use them and what you enter, not from settings or configuration. stuff that changes itself in real time, just by being used. we wouldn't build that kind of software today because it's too weird or specific. but with this, it just happens.

still super early and pretty rough, but it feels like a door opened a crack.

When putty was written it was the era when people had personal websites and made software for fun or to help them in their daily lives.

It was a time people used mirrors, because while a connection to the far east was possible, it was painfully slow for a variety of reasons

https://www.chiark.greenend.org.uk/~sgtatham/putty/mirrors.h...

Since the late 00s though the world has changed and very few write software for fun, or to scratch an itch. It's always a hustle, waiting to be monetised or at the very least to pad a resume.

I like the fact part of the old world still exists in such a high profile area.

It started on forums, bled into social media, and now it’s used by advertisers trying to capture the people who recognize it from forums and social media.

Interestingly, the businesses targeting this segment have pivoted into offering actual testosterone prescriptions, pill-mill style. They’ve discovered that if they can find a willing doctor then there are no consequences for writing mass prescriptions for testosterone as long as they can create a minimal paper trail documenting some symptoms. So people see an ad on social media or hear one on the radio, make an appointment, and the doctor quickly diagnoses them with “low T” based on vague symptoms like “not performing as well as I’d like in the gym”, and they get a prescription.

The business model is to charge a monthly fee such as $200/month. Once people start taking testosterone their body shuts off its natural production, meaning they feel devastated if they ever stop taking it. So the customer is hooked. Some people can discontinue and eventually recover, but most people who take it for years will have testicular atrophy such that they may never be able to live without testosterone injections again for the rest of their lives. This inconvenient fact is rarely communicated up front, of course.

>They'll just declare that modern medicine has recognized and assimilated the concepts of traditional Chinese medicine

That's actually happening though. See this text for example: https://www.amazon.com/Introduction-Western-Medical-Acupunct...

Chinese civilization has had a population of hundreds of thousands of people going back many hundreds of years. It's not the least bit surprising that they've figured out useful stuff about medicine. Even if you believe that the TCM theories are wrong, and it was all trial and error, the default position should be that it's possible to identify useful treatments through trial and error. It's Western chauvinism to believe that useful treatments can only be discovered via Western methods.
by Brian_K_White | 2025-07-14 13:41:27+00:00
The criticism is that they claimed to have the solution the first time, instead of only claiming that they will try something functionally random.

A methodical process and a random or intuitive process only look like the same trial and error on the outside, and only to the (probably willfully) ignorant.

The trappings and ceremony of a theory and methodology are not actually a theory or methodology.

It doesn't do anyone any good to allow any confusion of the two.
Show HN: CoverPaste – A simple cover letter generator
by novaheic | 2025-07-14 13:41:45+00:00
I've been writing cover letters for over 10 years now, across a variety of industries and seniorities. Initially, my approach was to plan 4-8 hours for writing the perfect cover letter tailored exactly to each specific role and my personal experiences/background.

Just last year, I spent a whole day writing one for a position I was perfectly suited for - a job I really wanted. And well, I never even got a reply. That's where my strategy changed. I realized most employers now overwhelmingly use AI tools to look through cover letters, and it matters more whether you have a cover letter (or not) vs. the actual quality of the letter.

So, I decided I would no longer spend hours crafting each ideal letter, which was also limiting the number of jobs I could apply for, and I increasingly began using GenAI. Initially, just for some inspiration, but pretty soon I had a whole workflow: I would upload my CV and 1-2 past cover letters I was really proud of, along with the job description, and the prompt I had refined over time. Then I would copy/paste the result into a Google Doc, edit, and download the PDF.

In the past 3 months alone, these letters have landed me interviews at McKinsey, KPMG, and BMW.

Just recently, I decided I wanted to fully automate this workflow, so I built a simple user interface that would allow me to just upload my documents and hit generate. Then I put in an editor and a way to directly download the PDF so I could stop filling my google drive with a bunch of random cover letters.

So while this has worked pretty well for me, I would really appreciate some feedback. Is this tool useful? Anything you'd change? You can use the code NOVA20 to get 20 free cover letters.
by anton-c | 2025-07-14 13:41:51+00:00
I think it's a shame avoidance and marketing effort. It's not flattering for a man to admit he thinks he has low testosterone. Easier to talk about.

There is some fake shit no doubt, but you can have real problems that lower it. Kills dudes motivation, libido, etc and that kinda spirals towards depression sometimes. But it's not meant for long term use or meant to be given out as willingly as it is.

Anecdata to the contrary: on my Android devices I've switched from Brave to Firefox maybe a year ago (exactly because of the Lobste.rs story) and I found out performance to be completely acceptable for my needs.

And both solve youtube ads, which is how high I set the bar.

American support before the US entered was crucial on the western front. But it's generally agreed that the turning point of the war against the Nazis was the Battle of Stalingrad, which the US played no part in (other than occupying Nazi forces elsewhere). However, a great effect of the US joining was that the USSR didn't conquer France. The second half of the the twentieth century could have looked very different if the US had stayed out. In other words, it might not be really accurate to say the US beat Hitler, but it is accurate to say they halted Stalin's advance. It could be argued that D-Day won the Cold War, it just took a long time for that to play out.

VC funding subsidizing the entry of these firms into the market. Few competitors contributing to pricing power among these firms. Network effects arising from coordinating the multi-sided market of drivers, restaurants, and consumers.

Early subsidization has led to the position of these firms as middlemen that can extract something akin to rent from their dominant market position. The vig that middlemen collect isn’t a benefit to consumers but something they pay for with every transaction (price mark ups, service fees, narrowed choices).

No, profit isn’t a sign of consumer benefit. Often it’s quite the opposite actually.

And let us be very clear: this happened REGULARLY pre-AI, with long-lived systems adding contractors 12, 6 or less months over 20 or more years. Now we have AI that allows even faster iterations of this with even less conceptual integrity.

The big problem: the decision makers(c-suite executives) never really understood what was happening before, so you can't expect them to see the root cause of the problem we're actively creating. This means it will not get the attention and resourcing needed - plus they'll be gone and on to the next one after taking a huge payday for slashing their R&D costs.
