What I haven't seen anyone mention yet is that syntax exists to concisely express semantics. If you want to give me an immediate feel for your interesting semantics, show me how you express them syntactically.

It may be easier to explain (for instance) Rust's borrow-checker in prose, but if you show me a snippet of code using `&mut`, it'll click for me intuitively that something conceptual and important is happening here. That's why I want an illustrative example at the top of the front page.

With satellite trackers and social media these kinds of events have developed into a spectator sport. Bikepacking races tend to be in more remote locales than the French countryside so racers are required to carry a satellite tracker which reports to a public website. "Dot watchers" who live along the route come out to watch racers go by or leave water/snacks in coolers along the side of the road. Far more dot watchers are limited to the live tracker and check daily updates from racers or journalists covering the event on social media.

After the event some racers upload videos for spectators and it helps them with sponsorship. This video gives a glimpse into what its like to race the Tour Divide competitively. https://www.youtube.com/watch?v=azJS106xeNA

Blackrock may reconsider its lawsuit against UnitedHealth because at this point something can happen in their corporate HQ as well.

Corporates in USA needs to start thinking about self preservation and encode it into the way how they are doing business or they will go bankrupt out of fear. They may be rich enough to buy C-suites a security detail, but not rich enough to have a bodyguard for every single employee. And if employees are scared for their life they may stop doing things which ma have them killed. And it does not matter what C-suites want or if they will be fired. It might be more appealing to get fired than fired at.

What I missed from the article is the usual: biometric authentication is not secure.

(Yes, I'm linking YouTube because unlike popular belief, some channels are actually informative, or some make it easy for us to understand the content.)

I would never use my fingerprint for authentication, because it's a flawed concept. The problem is, that your fingerprint is not a password. It's more like a username. That's because you leave your fingerprint everywhere, it's practically public information. The same can be told about your face.

How would the app know your high energy times? My phone sits idly on a desk while I am actively working, while I am sleeping, while I am out on a walk, while I am painting, swimming, or canoeing around a lake. To my phone, those all look exactly the same. So unless you tell me to actually pick up and use my phone more often, or to tell it what I am doing... both of which I would reject... I'm not seeing how it can figure out my energetic times.

Oh, good grief, in that case you might want to start with a Pilot medium (roughly equivalent to a German no. 5 'fine') and work down from there. Without wishing to invite contumely on the sometimes extremely fractious topic that can be Noodler's inks, I will say my experience is that all the feed and nib throughput you can possibly give them will never really be too much, especially in Japanese pens.

>Pi seams to be a property of the universe

If you also agree 1 = 1 is a property of the universe, sure... But these are really just linguistic notations stacked upon each other until statements like 2pir = c are true.

I can write plenty of other true statements, I can make some strange irregular shape and prove the area of it.

>There is a longing in people for love, happiness and justice which seams to be universal through the earth population?

At a minimum moral relativism, between cultures, people, eras, organizations vs individuals seems absolutely true. At one point, being a pirate was honorable because it helped your community.

The key insight: CDNs were built for a different era. When your "edge" is just a cache, you're still backhauling every dynamic request to the origin. Modern platforms run your entire stack distributed - SQL queries, AI inference, full application logic - right where your users are.

This isn't "Akamai bad, Azion good" - it's about choosing the right architecture for modern applications.

Opaque walls are on the predator's side. Removing the always-on government microphones and cameras in your house is giving shelter to child predators. Remember that car ramming attack, how we couldn't find out what the perpetrator had said in the last few minutes of his life? If you disable the microphones in your car, you're helping terrorists. Non-transparent umbrellas are helping criminals evade facial-recognition cameras as we speak - turn yours in today at any privacy amnesty police box.

The smallest scrap of freedom or privacy you ignorantly cling to is causing children to be killed and abused. Convert your country into an open-air prison, or you are complicit in their deaths.

Question: I know that our planetary probes often use planetary gravity to boost their speeds. That only works for prograde speeds, right? Because you're subtracting a miniscule amount of orbital speed from the planet and adding it to your spacecraft's speed. You couldn't whip around a planet and somehow use that to give you retrograde speeds, could you? (Presumably an airless planet, like Mercury.) Or what about using a large moon during the retrograde (relative to the planet's motion around the sun) part of its orbit?

My key to LLM study has been to always primarily use a book and then let the LLM allow you to help with formulae, ask questions about the larger context, and verify your understanding.

Helping you parse notation, especially in new domains, is insanely valuable. I do a lot of applied math in statistics/ML, but when I open a physics book the notation and comfort with short hand is a real challenge (likewise I imagine the reverse is equally as annoying). Having an LLM on demand to instantly clear up notation is a massive speed boost.

Reading German Idealist philosophy requires an enormous amount of context. Being able to ask an LLM questions like "How much of this section of Mainländer is coming directly from Schopenhauer?" is a godsend in helping understand which parts of the writing a merely setting up what is already agreed upon vs laying new ground.

And the most important for self study: verifying your understanding. Backtracking because you misunderstood a fundamental concept is a huge time sync in self study. Now, every time I read a formula I can go through all of my intuitions and understanding about it, write them down, and verify. Even a "not quite..." from an LLM is enough to make me realize I need to spend more time on that section.

Books are still the highest density information source and best way to learn, but LLMs can do a lot to accelerate this.

iGPUs are typically weak, and/or aren't capable of running the LLM so the CPU is used instead. You can run things this way, but it's not fast, and it gets slower as the models go up in size.

If you want things to run quickly, then aside from Macs, there's the 2025 ASUS Flow z13 which (afaik) is the only laptop with AMD's new Ryzen Max+ 395 processor. This is powerful and has up to 128Gb of RAM that can be shared with the GPU, but they're very rare (and Mac-expensive) at the moment.

The other variable for running LLMs quickly is memory bandwidth; the Max+ 395 has 256Gb/s, which is similar to the M4 Pro; the M4 Max chips are considerably higher. Apple fell on their feet on this one.

An even easier way to construct new puzzles is to fully randomize the problem statements and intended solutions.

When you take out the information from the variable names, you're making the training data farther from real-world data. Practicing walking on your hands, while harder than walking on your feet, won't make you better at hiking. In fact, if you spend your limited training resources on it, the opportunity cost might make you worse.

I have used the Don't Fuck With Paste extension https://addons.mozilla.org/en-US/firefox/addon/don-t-fuck-wi... in Firefox for a few years. Seems to work well when I need it (and when I remember to try it, as it needs enabling on a per-site basis).

For removing tracking query parameters from the URL I've used ClearURLs https://addons.mozilla.org/en-US/firefox/addon/clearurls/ for a few years.

uBlock Origin is still fully functional in Firefox as well so I guess I could find a way to block the "Sign in with Google" prompts somehow with a custom rule.

They've been dominant. ChatGPT is still the better consumer AI tool but Anthropic models have been better for professionals.

When I use Github Copilot agent mode, Sonnet 4 is worlds better than GPT 4.1 and Gemini 2.5 Pro.

What I mean by a "spectator sport" in this context is primarily that the event can be monetized because huge numbers of people will watch it either in person or via video of some sort.

The number of people watching the trans-europe or other similar solo events as they happen is likely less than the population of a typical US liberal arts school. The monetization that might follow from YT videos that occurs later is completely different from what the TdF manages to encourage. The winner of 2023's Tour Divide has 58k views ... even Lael only gets 300k or so views for her adventuring and racing videos. This is not a spectator sport in any sort of historical sense of that term.

Are we reading different pages? Their pricing page: "Choose 5x or 20x more usage per session than Pro*". Per session is the important bit here.

I do see that their sign up/registration page doesn't include the per session text, instead saying just "5-20x more usage than Pro". I do think the per session but is the part that makes it true, but I also don't think you're being skeptical enough. If something says 20x more I'm obviously going to look for 20x of what, and I think it's on the reader to realize what they're signing up for.

I don't have any stake in this, anthropic, or AI; but I don't like it when people flame something that I think is understandable. It's certainly a bit of spin, but I don't wouldn't go so far as to say it's unethical etc.,.

Any kind of distraction is likely to impact human test scores, unless the test is well below their level or they're otherwise very comfortable with the subject matter. Math specifically makes most of the general public feel a bit in over their head, so tossing random cat facts into the mix is going to get people more confused and nervous.

Maybe I'm totally wrong about that, but they really should have tested humans too, without that context this result seems lacking.

Netflix discusses their reasons starting at 18:20: https://www.youtube.com/watch?v=veQwkG0WdN8&t=18m20s

tl;dw: the performance, the efficiency of development, the community, FreeBSD is a complete operating system, the code base is smaller, the ports system, and the license.

and this video covers the optimizations Netflix has made to FreeBSD: https://www.youtube.com/watch?v=36qZYL5RlgY

Also potentially a reason: According to drewg123, Linux's kTLS was broken. Which I see drewg123 also commenting in this thread. Is he the "Drew on my team" mentioned in the first video? Is he the speaker in the 2nd video? Idk https://news.ycombinator.com/item?id=28585008

I really don‘t like the tone and implication of your post. When you say stuff like “the collective Middle Eastern mentality that despises weakness and worships victors”, “The Palestinians are largely looking for the destruction of Israel”, and “The Palestinian and Jewish populations are not compatible with each other”. You are generalizing over a large population with varying views, and makes you look like a bigot and a racist.

I‘m gonna answer your strongest points on material grounds though, and ignore your more racist stuff.

> The "right of return" (meaning the inflow of millions of third, fourth and fifth Palestinian descendants from neighbour Arab countries) is their - and the Arab's world - tool to dismantle Israel.

That is a) just your opinion, and b) irrelevant in the context of human rights. The Palestinian were unjustly expelled and they have a right of return under international law. Israel had no right to expel them in the first place, the expulsion was a historic wrong, and for justice to resume they are owed the right of return as well as reperation. Whatever that does to Israel’s demographics is a non-concern in the context of international humanitarian law. If such a right were granted and it would result in Israel no longer being a majority Jewish state, that would simply be a new reality we would have to deal with. Minority rights are a thing that international law also guarantees, and surely Jewish Israelis should be happy living is a minority in a land which guarantees their rights as such.

> The suggestion that Jews admit defeat, hand their heads to Hamas and the likes and ask for forgiveness does not resonate as sane.

We have been here before, and yes, this is the sane option. Rhodesia admitted defeat to the terrorist organizations ZANU and ZAPU, South Africa to the ANC, The French Algerians to the FLN (which was probably more brutal than Hamas). And outside of settler colonies we have South Vietnam admitting defeat to the Viet Cong. Brutal regimes which owe their existence to the oppression of others like Rhodesia, Apartheid South Africa, French Algeria, and South Vietnam are frequent targets of terrorists, those same terrorists often become the ruling power post liberation, and the settler (or otherwise the beneficiaries of the past oppression) most of the time are able to live just fine under their new rule without the systemic oppression. In all likelyhood, even if Hamas were to rise to power in a post-apartheid Israel state (which honestly is rather unlikely) chances are they would not be able (nor even willing) to exert the kind of oppression onto a hypothetical Jewish minority in such a state.

I don’t believe in god, but this kind of thinking feels like playing god.

It is really hard to guess what is the right way, everyone has a different idea.

Effort and resources seems like the biggest missing piece in practice.

In almost everything more effort and resources seem to be able to overcome a lot of bad decisions and mistakes but there is not much hope if there isn’t enough effort.

Oh for sure, I wouldn't blame anyone for being misguided by these symbols, and generally these wrathful practices aren't even taught until a practitioner has had quite a lot of experience in their meditation practice. It's far too easy to think "oh, well I'm a compassionate being just like Mahakala, therefore I should be able to hit my child because I know what's best for them". That's of course not what is being depicted here. What is being depicted is transforming the five afflictive emotions [1] into their positive wisdoms [2].

And we should also put these symbols into the context of a Buddhist worldview -- that a human life is not guaranteed, and even if we get one and survive into adulthood, most will go about their regular lives without using this opportunity to do the deep work necessary to escape our self-inflicted cycle of suffering. The wrathful symbol is startling by design, to say "hey! wake up and do something about your life, it'll end soon".

So that's all to say, we should focus on the metaphors that they embody rather than their literal depictions.

Are you serious right now? Have you lost all sense of relativity here?

Nobody cares about what these employees say on their free time. If you collated the things IDF members say on social media about Arabs, it would not look any prettier. It's a complete non-sequitur and emphasizes how insecure you are over the actual righteousness of these actions.

> “It is regrettable that we now have to spend time and resources strengthening the security of a popular service rather than further developing functionality for the benefit of our customers.”

Based on all the data leaks that happen constantly on cloud connected, data harvesting services, I have zero faith that these companies care about security. These companies couldn't care less if they leak personal data online, but god forbid someone is trying to root our device or flash another OS, now suddenly we need to strengthen our security. Fuck these people frankly.

>Unless it was common enough to show up in a well formed question on stack exchange, it was pretty much impossible

sorry but if you've gone to university, in particular at a time when internet access was already ubiquitous, surely you must have been capable to find an answer to a programming problem by consulting documentation, manual, or tutorials which exist on almost any topic.

I'm not saying the chatbot interface is necessarily bad, it might be more engaging, but it literally does not present you with information you couldn't have found yourself.

If someone has a computer science degree and tells me without stack exchange they can't find solutions to basic problems that is a red flag. That's like the article about the people posted here who couldn't program when their LLM credits ran out

I've read through them here, they're not bad at all. There's a majority opinion, and people are disagreeing, but there's real content there instead of campaign slogans and insults. But HN rules say it's not for politics, so I avoid participating.

So what is your non-cesspool forum example that isn't Reddit? Twitter seemingly got taken over by bots early on, Facebook pages were a disaster at least when I was in college, and those are the big ones.

If art is communication- and i believe it is- why would i want to read or listen to anything AI generated? Once you are done with consuption there is no point in reflecting on it nor having a conversation about it with other fellow humans. People are not even interested in each others dreams most of the time. Unless the machine is of godlike intelligence there is just zero point.

For self-hosting, there are a few companies that offer per-token pricing for LoRA finetunes (LoRAs are basically efficient-to-train, efficient-to-host finetunes) of certain base models:

- (shameless plug) My company, Synthetic, supports LoRAs for Llama 3.1 8b and 70b: https://synthetic.new All you need to do is give us the Hugging Face repo and we take care of the rest. If you want other people to try your model, we charge usage to them rather than to you. (We can also host full finetunes of anything vLLM supports, although we charge by GPU-minute for full finetunes rather than the cheaper per-token pricing for supported base model LoRAs.)

- Together.ai supports a slightly wider number of base models than we do, with a bit more config required, and any usage is charged to you.

- Fireworks does the same as Together, although they quantize the models more heavily (FP4 for the higher-end models). However, they support Llama 4, which is pretty nice although fairly resource-intensive to train.

If you have reasonably good data for your task, and your task is relatively "narrow" (i.e. find a specific kind of bug, rather than general-purpose coding; extract a specific kind of data from legal documents rather than general-purpose reasoning about social and legal matters; etc), finetunes of even a very small model like an 8b will typically outperform — by a pretty wide margin — even very large SOTA models while being a lot cheaper to run. For example, if you find yourself hand-coding heuristics to fix some problem you're seeing with an LLM's responses, it's probably more robust to just train a small model finetune on the data and have the finetuned model fix the issues rather than writing hardcoded heuristics. On the other hand, no amount of finetuning will make an 8b model a better general-purpose coding agent than Claude 4 Sonnet.

>But majority of the people (as seen with China, or Russia) do not care about VPN and won’t care

The article that our comments are under are about an 18x increase in sign-ups from the UK for one provider, a 2.5x increase for another provider, a 10x increase for yet another provider, etc. in just days.

I'm curious about your stats for China/Russia, though. Where/how do you find out how many internet users in those countries have a subscription to and/or use a VPN? Would those stats continue to hold true if there was not a great firewall in China, and just rudimentary IP-blocking of VPN providers?

from GP:

> Team Sky said that during a time trial stage bikes might be heavier to allow for better aerodynamic performance

(emphasis mine)

TDF time trials are almost never uphill. And yes, they have different bikes, showing that that while they might trade mass for drag during a time trial stage, they would do the opposite for hill climb stages. So "aero is the only thing that matters" is clearly false.

It’s exciting when I discover I can’t replicate something that is stated authoritatively… which turns out to be controversial. That’s rare, though. I bet ChatGPT knows it’s controversial, too, but that wouldn’t be as much fun.

On the subject of LLMs and cats, I continue to find it disappointing that if you search for one of the leading AI services in the Apple App Store that they all seem to have centralized on images of cats in their first app screenshot as the most-converting image in that setting

Edit: a quick re-search shows they’ve differentiated a bit. But why are cats just the lowest common denominator? As someone who is allergic to them any cat reference immediately falls flat (personal problem, I know).
