Something I've heard physicists say but doesn't make sense to me is, "gravity is a just a distortion in space-time, it's not like the other forces." Can someone with more knowledge than me explain this? As far as I can tell:

1) General relativity is just a model.

2) The force that was observed as gravity can be modeled as a a distortion in space-time.

3) Thus (circular logic incoming), gravity is not actually a force, it's just a distortion in space-time, and that why it looks like a force.

This is just begging the question. I could say the exact same thing about any of the other forces between particles, just instead of using the permanent[0], I'd use the determinant[1] for fermions or the immanant[2] for anyons.

I remember in my electrodynamics class applying relativity to Coulomb's law, and seeing the magnetic force just pop out in the Taylor expansion (and I just learned the Feynman lectures does this too: II_13-6[3]). So what do physicists mean when they say gravity is special, or general relativity doesn't play well with quantum dynamics?

There's sort of two ways to look at the Teenage Engineering products. The first is as a tool to produce music, and the second is as a kind of interactive sculpture. The design and production of these things is so good they are almost like art themselves. Are they useful? Not really, you could achieve the same thing with a VST — hardware isn't required for this — but to think in this way is to miss the point.

Are sculptures, picture frames, decorative vases and ornamental unused candles unnecessary?
By that same reasoning, a Tesla would need about 8-10 times more battery than it actually has. A common battery size for a Tesla is around 65 kwh. A gallon of fuel is about 31kwh. So by your reasoning, a Tesla should have the range of a car with only a 2 gallon tank. And of course they have quite a bit more range. They do about 4-5 miles per kwh. That's the equivalent of a car that does 120-150 miles per gallon. Good luck finding such a car. ICE cars are super inefficient. Even hybrids that use a generator to power their batteries (as opposed to dual electrical and ICE drive trains) don't come close to those kind of efficiencies.

Most of the energy in a gallon of fuel is converted into noise and heat. Most of the energy in a battery gets used by the engine for its intended purpose.

So, battery energy density should be a lot closer to what is needed than what you calculate here. It's still not ideal of course. As for the engine, I would expect an equivalent electrical motor (in power output) to actually be smaller and lighter than a petrol engine. If you take electrical semis as an example, you can actually pick up the motor and carry it around because it's small and light. Forget doing that with a typical diesel or petrol engine in even a small car.

As for the battery you mention, that was first launched in 2015. It's an old battery design. Hardly state of the art at this point. And probably not even back then. Husqvarna could probably update that with more modern cells and more than double the energy density. Going to solid state they could push it even further. There are some products with solid state batteries coming on the market now. I saw a review of a portable generator recently, for example. I think it's probably more cost constrained than technology constrained. But this stuff is definitely coming now.
As with anything battery, refuel tme is also an issue.

A tiny gas tank, 1 gallon, can refuel a chainsaw dozens of times. In seconds. Carrying 100s of batteries isn't viable, nor is the economic cost of them.

We are getting there. Probably within a decade, we'll have a 2x or 4x power density leap in people's hands, and the equations will change. To me though, charge time is what will make a bigger difference.

If we could reduce charge time by 10x, that's huge. Everything would change.

And that will happen.
I wonder if the immune system plays a role. In one environment there is some stressor (e.g. smoking) which raises for example lung cancer risk, but also turns up some built-in anti-cancer systems in the body - the action of which which would prevent cancers in other areas. Compare to a person in a better environment where the immune system isn't as much in "cancer-prevention mode".
Taxes on fuel are a way to deincentivize the use of private cars, at least in my country with the fuel tax you can't pay all the infrastructure cars use.
Not GP, but smart phones and social media lead to people having less real-world contact, fewer deep connections to others, less sex, ... which then leads to depression, anxiety, and "metaphysical despair"

I suppose that's what GP meant.
That's a very interesting point. I had never considered it. I have always conflated the perception of change with change itself.

What you wrote was quite profound to me! Thanks.
As I understand things, US law lets US spy agencies get secret warrants, requiring Google and AWS to give them access to everything while keeping the existence of such access secret.

EU law, meanwhile, prohibits such access, under the GDPR.

There is an obvious conflict here, when a US cloud provider operates an EU data centre.

Luckily, cloud providers have never received a secret warrant they can't reveal the existence of wink and spy agencies would never operate outside the law wink so the apparent conflict has never arisen in reality wink
Yeah it is to some degree. I tried to use it as much as possible, but there's always those annoying edge cases that makes me not trust the results and I have to check everything, and it ended up being faster just building some simple UI where I can easily classify the name myself.

Part of the problem is simply due to bad data from the websites. Just as an example - there's a 2-week contact lens called "Acuvue Oasys". And there's a completely different 1-day contact lens called "Acuvue Oasys 1-Day". Some sites have been bad at writing this properly, so both variants may be called "Acuvue Oasys" (or close to it), and the way to distinguish them is to look at the image to see which actual lens they mean, look at the price etc.

It's true that this could probably also be handled by AI, but in the end, classifying the lenses takes like 1-2% of the time it takes to make a scraper for a website so I found it was not worth trying to build a very good LLM classifier for this.

Show HN: 500+ Machine Learning and AI Questions Quiz
Compiled 500+ Machine Learning and AI questions into a quiz.

It tries to touch on most major topics in ML and AI.

If you come across a question whose answer you doubt, please share the link and I'll check it again. Any recommendations or changes, please let me know.

On how the quiz works - correctly answered questions are stored locally, so you won't see a question again if you answer it correctly. If you want to see all questions again, there's a reset quiz button. Questions are ordered randomly but there is a sort button. There is a dropdown if you want to skip to a particular question Id.

Questions answered correctly will autoslide to the next question. You can turn this off. Each question, once answered, will provide a bit of context for the answer.

So what's your score?

Summary:

- It's not just increased screening/detection because mortality went up. This affects half of the 34 types studied. Examples mentioned are pancreatic, liver in women, various gut, colorectal, kidney, gallbladder, testicular, and breast (may have missed some because it's sprinkled throughout)

- "there are likely unidentified risk factors but there are also known [ones], like sedentary behaviour, a change in diet, plus rising rates of obesity and diabetes." "[Many young patients] exercise regularly and eat healthily"; microplastics "fit the timeline [but] needs further investigation"

- Earlier screening is being considered but comes with "expenses, radiation exposure and false positives"
A "better" way is to modify the package-lock.json. You can still spoof the package but almost no one actually reviews it as npm will usually modify 1000s of lines.

for example take mongoose

"resolved": "https://registry.npmjs.org/mongoose/-/mongoose-8.4.4.tgz",
"integrity": "sha512-Nya808odIJoHP4JuJKbWA2eIaerXieu59kE8pQlvJpUBoSKWUyhLji0g1WMVaYXWmzPYXP2Jd6XdR4KJE8RELw==",

so long as the integrity check passes for the resolve url npm will happily install it.

Chicken-and-egg: paddle payment rejected me as I have no processing statements
Recently I am trying to apply and integrate a payment solution for my SaaS. I did an investigation and get to know new concepts such sales tax, MoR (Merchant of Record) etc.

Paddle(https://paddle.com) seems to be a good choice for my case as they can handle sales tax for you, so I applied for Paddle.

However, in their domain verification step, I was rejected because my SaaS do not have prior processing statements (aka, transactions history).

The response:

```

To clarify, you will need to provide processing statements from a payment processor for at least the past three months. These statements help us assess your transaction history and ensure everything aligns with our requirements.

Yes, it typically means that you’ll need to integrate with another payment processor and generate some transaction history before applying for Paddle. Once you’re approved by Paddle, you can then migrate your customer data to our platform.

```

This is kind of ridiculous requirement for a new SaaS product. No payment solution -> no transactions, no transactions -> cannot apply paddle, the chicken-and-egg dilemma.

And if I already integrated another payment solution (such as stripe), then why should I migrate to paddle then? I can just work with some tax solutions (contract or SaaS) to get the same as Paddle can do.

I am not sure how many people got the same experience with Paddle. Just posted my experience here FYI.

If that were the case you would see rising rates of cancer across all cohorts.
If you read the actual study referenced in the article you'll find that 10 of the 17 cancer types which are rising in the young cohorts are obesity-related. Lung cancer is actually down for the younger cohorts.

Another interesting find was a rise in anal cancer and Kaposi's sarcomas which are mostly related to HIV infections.
Nazism is dead. There is no significant nazi organisation on this planet. Yes there are still white nationalists. Yes there are still anti-semites. This was also true before the Nazi party existed. And during its existence! If WWII commander General Patton of the US Army had a twitter account, it would probably have more of the above than both the accounts you linked.

So, I re-iterate. If you're unironically calling people Nazis in 2024, you're either a political extremist, not all there in the head, or completely ignorant of history. Often it seems to be a combination.
China is accumulating commodities that will make its currency a dominating one in the global reserve currency space. It's a long term play, and I don't believe it has anything to do with Trump or Taiwan.
Unfortunately no, but i can share some insights that i hope can be of value:

- Tech: Everything is hosted in AWS. We are using Golang in docker containers that does the scraping. They run on ECS Fargate spots when needed using cronjob. The scraping result is stored as a parquet in S3 and processed in our RDS Postgresql. We need to be creative and have some methods to identify that a particular product A in store 1 is the same as product A in store 2 so they are mapped together. Sometimes it needs to be verified manually. The data that are of interest for the user/site is indexed into an Elastic search.

Things that might be of interest:
- We always try to avoid parsing the HTML but instead calling the sites APIs directly to reduce scraping time. We also try to scrape the category listing to access multiple prices by one request, this can reduce the total requests from over 100 000 to maybe less than 1000 requests.

- We also try to avoid scraping the sites during peak times and respect their robots.txt. We add some delay to each request. The scrapes are often done during night/early morning.

- The main challenge is that stores can redesign or modify which make our scrapers fail, so we need to be fast and adopt to the new changes.

- Another major hidden challenge is that the stores have different prices for the same product depending on your zip code, so we have our ways of identifying the stores different warehouses, what zip codes belong to a specific warehouse and do a scrape for that warehouse. So a store might have 5 warehouses, so we need to scrape it 5 times with different zip codes

There is much more but i hope that gave you some insights of challenges and some solutions!

I anecdotally agree that GPT-4o often feels really bad, but I can't tell how much of this is due to becoming more accustomed to the quality and hallucinations of using ChatGPT.

I tend to see Huggingface's LLM (anonymized, elo-based) Leaderboard as the SoT regarding LLM quality, and according to it GPT-4o is markedly better than GPT-4, and contrary to popular sentiment, is on-par with or better than Claude in most ways (except being slightly worse at coding).

Not sure what to believe, or if there is some other dimension that Hugginface is not capturing here.

Another way of looking at it is survivorship bias.

All,

Founder of Plunk here.
Yes, Plunk is designed to work with AWS SES. I was not the one that made it hard for folks to self-host their own email infrastructure. SES is simply the cheapest and most reliable option out there. Reminder, we are not talking about a private "let's send 10 emails a day" solution. This needs to deliver marketing emails at scale.

Does that mean you have to use SES, no. The code is open-source, swap it out for another provider if you truly believe that you can do it better. I'm open for contributions.

That's the beauty of open-source.

I think that rather than being a matter of having or not faith in a future breakthrough, the difference is between those who believe that there's already been a major breakthrough in the last few years and those who deny it.

It's disappointing to hear that Paddle requires three months of processing statements before allowing integration for new SaaS products. This creates a classic chicken-and-egg dilemma: without a payment solution, you can't generate transactions, and without transactions, you can't qualify for Paddle.

For new SaaS products, starting with an alternative payment processor like Stripe, which does not have this requirement, seems to be a necessary step. Stripe is straightforward to integrate and widely trusted. After generating the required transaction history, migrating to Paddle for its comprehensive tax handling could be considered.

Alternatively, many tax solutions can integrate with Stripe, providing similar benefits to what Paddle offers without the initial barrier.

This requirement seems counterintuitive and might deter new businesses from considering Paddle from the start. If Paddle could reconsider or provide a pathway for new products without existing transaction history, it could be more appealing to startups.

Your Elixir feedback is strange. I find it very explicit. Can you give some examples what you find clever / implicit about it?
logind provides features developers of software that use them want or like, people aren't adopting it just for the sake of it.

e.g. GNOME Shell now uses systemd user services to manage its sub services rather than starting them itself. Why? Because systemd does service management a lot better and provides proven features (logging, sandboxing, cgroups etc) rather than GNOME having to re-implement them.
Needed but not sufficient: FLOSS demand an active development community, who demand active DESKTOP developers. Currently young generations born on modern commercial software/services do not understand desktop model, they just try to mimicking commercial cloud+mobile model, there is no FLOSS future possible with such paradigms.

Desktop development in the past was locked by widget based GUIs and their limits, they are not classic editable DocUIs, modern WebUIs are the commercially needed answer since they are DocUIs BUT not under user control. Most modern devs simply use WebUIs, even locally, because they can't even imaging an editable DocUI. When some colleagues see rare presentations from me (I talk a lot, but hate slides) in Emacs/EXWM/org-mode/dslide can't even understand what their see. Live rendering of an active markup witch is indeed free form text eventually with executable code (elisp: links or C-x C-e full displayed sexps) is something they can barely understand, having the same language, functions available everywhere is totally alien for most.

Even if we have the code, if the coded software is something unsuitable for personal, SME usage being just a copy of some big tech walled garden, the code alone does not suffice. Having the entire Alphabet infra under AGPL does not fit much any FLOSS purpose. It just allow big tech interoperability witch is their biggest Achilles's heel since having no walled gardens, an OS as a single application in user programmable hands interconnected with other desktops as well, is the strongest FLOSS point no one company can aspire to match no matter their size.

FLOSS need a FLOSS IT paradigm BEFORE the code, we have more than enough code not to care about "OSS Enterprise" models, we miss instead the knowledgeable user base and desktop paradigm.
