> define BEING and END as { and } respectively

I know this is a typo, but I love the idea of using "BEING" and "END" as delimiters. Maybe "BIRTH" and "DEATH".

Hi HN,

I built this tool to explore Claude (Haiku)'s capacity to make free associations on a concept, and chase the chains of associations outwards. Give it a try! (Press the reset button for a blank slate).

Any feedback is welcome.

I don't know why this is necessary. If a particular IP is hammering your site, it's sufficient to intelligently give HTTP 429 errors to encourage the IP to discipline and temper its requests. It works as well as anything else. If you don't want clients to access data, put it behind a login, not on the open internet.
Are you exercising enough or do you need to exercise more is an actionable question worth asking.

I live in FL, that take is FUD from those with vested interests in taxable incomes.

FL is a great place to retire, and no state income tax is only one out of 1,000s of reasons to move to FL instead of where you're currently residing.

If you're a remote worker, or retired you just can't beat Florida's no income tax, great climate, and affordable living.

If someone is telling you different, they're trying to sell you something. We don't have to sell anyone on Florida, here, as it sells itself many times over.
Hmm, so like one seventh to one quarter of the way (depending which of us is counting) to feeling perceptibly close and stuffy. Useful context.
The book Beautiful Racket is the best defense of macros out there, on "show, don't tell" grounds. Also, it's just so well-written and describes such an interesting set of tools that I'd argue it's worth a skim even if you don't intend to learn the language.

You have to read the whole argument, to get past "Full-disk encryption achieves the same end" where they're equating the encrypted-on-disk with ephemeral RAM.

Only once you get to a later claim that the logs they store on local disk "contain no personal information" (they claim; even in event of error?) is the earlier claim arguable for a relevant threat model.
Too many texts is annoying to read and understand. Bad representation.
Neat, I was looking for such a tool a few days back and ended up not having the requisite google skills to find this (embarrassingly, it seems easy it find now)

I ended up writing my own script for visualizing my particular problem (trying to work out what's going on in the "mett" data frames in videos from my pixel phone, I was able to make some headway but I've gotten distracted by other projects, if anyone has info I'd appreciate it)
I share on hacker news because:

1. I want the knowledge/experience/anecdotes/opinions of others.
2. I want to share my own knowledge/experience/anecdotes/opinions with others.
3. Contributing low-bandwidth, high-quality* content is (hopefully) doing my small part in encouraging others to do the same.

My primary concern:
You are providing a map of individual user interests over a period of time. This is feels like a violation of privacy to some and is outright dangerous to others.

Why?
1. People have many interests. The Marketing Manager likes birdwatching, Bollywood, hacking podcasts, amateur chemistry, traditional Ukrainian breadmaking, ASMR, erotic independent film, rock climbing, pole-dancing, gunsmithing, and horse racing.
2. People are public with some interests, and private with others. The degree of public vs. private disclosure can come from external pressure (ie: political oppression, public servant expectations) or internal motivation (ie: embarrassment, pride).
3. People change over time. The 27 year old Marketing Manager may want to distance themselves from their poor political comments as a student.

Where to now?
If you stop work now, someone else will pick up where you left off. So how do make a system which balances the user AND allows you to continue?

1. Easy and simple opt-out option.
2. User profiles. Allow me to share /which/ interests are associated with me. I am a nuclear engineer by trade, but I'll be damned if I want to talk about it in my spare time. Let me opt-in to Birdwatching, and opt-out of nuclear engineering so those weirdos at work don't find me.
3. Limit the Time for association. Maybe that means you only 'connect' people with their comments in the past year as the Public default. Once the user connects with your system and has control over their online persona, then the user can decide what to show and for how long.

Future use?
1. Push this tool as an anonymity improvement tool, which also encourages meaningful conversations with people you want to connect with.
2. Feature: "We notice you posted for the first time to /r/bsdm with your /u/PepsiOfficialMarketing. Was this a mistake?"
3. Feature: "Our AI has scanned your recent posts. We have connected your writing style across two accounts and this may compromise the seperation of accounts. The following phrase: 'Do what thou does MFK!' was used to connect these accounts by our AI."

I have been there and this is what I finally settled to.
If he starting from complete newbie (no programming background etc), I would suggest start by learning programming only in well controlled environment. Be it python, MIT scratch (for start) or even Basic. Together with this you can try simulated robotics with something like Roboacademy[1]. It is a simulated robot, that you program with very simple instructions to solve pretty amazing problems.

The reason I say is this. Robotics is at the juncture of programming, electronics and mechanics. Learning robotics from zero is learning all of these 3 simultaneously and in a frustrating way. It is frustrating because, real world stuff breaks/faulty parts, misaligned parts, buggy firmware etc. Suppose you want to give a simple instruction move forward 3 seconds, turn right, move forward 2 seconds, but real world stuff has misaligned wheels, it wont turn exactly 90 degrees, it varies between servors/motors of the same model/make, there is jitter etc etc. So many fine-tuning and adjustments you have to make in the real world, and that takes focus and interest away from the creative fun part.

So my suggestion would be learn programming, learn a bit of electronics with age appropriate kits etc, before combining them to robotics.

Wow, really impressed with this! I'm sure my kids would absolutely love to build something like this, just as I would :)

Is there some kind of guide available? I've never built something like this before, but have some XP with Rpi and breadboarding. Oh, and I don't have a 3D printer.
If they are accused by the US of a crime, they could be extradited there because Switzerland has a treaty for that.
Iran has no beef with France, on the contrary, France was one of the and countries the most actively trying to get a deal with them. And there are 40 Iranian athletes at the Olympics.

Maybe! I see where you're coming from. That sounds like a long and painful road, still, though, from what is still a very dynamic language. Do you have a rough idea of how much more time/space-efficient a typical JavaScript program could be through this?
That's the same fallacy as the author of the article: No, Google doesnt “think you are an 18th century English criminal”, any more than it thinks the author “was a dead physicist”. It knows that he, the 18th century English criminal, was an 18th century English criminal. Just like it knows that the other guy, the dead physicist, was a dead physicist. It isnt talking about you (or the OP author); it's not as if you two are the only ones ever to bear your names.
Luckily, that is not necessary. You can make many mistakes, until you arrive at a logic you are happy with. Then you talk with other humans about it, and eventually you will all agree, that to the best of your knowledge, there is no mistake in the logic. If you pick first-order logic, that has already been done for you.

Then you need to implement that logic in software, and again, you can and will mistakes here. You will use the first version of that software, or another logic software, to verify that your informal thoughts why your logic implementation is correct, can be formalised and checked. You will find mistakes, and fix them, and check that your correctness proof still goes through. It is very unlikely that it won't, but if it doesn't, you fix your correctness proof. If you can indeed fix it, you are done, no mistakes remain. If you cannot, something must be wrong with your implementation, so rinse and repeat.

At the end of this, you have a logic, and a logic implementation, which doesn't contain any mistakes. Guaranteed.

Please don't, until burning of fields is strictly outlawed.

Burning of sugarcane to make it easier to harvest is a huge contributor to air pollution in SE Asia. And I believe some places in the US still allow it.
When a commercial jet schedules a flight plan, they must specify alternate airports, usually two are required especially when weather is predicted to be bad. The closest airport may not be the best one to divert to due to runway restrictions, normal capacity, and it must be far enough away for the possibility of it to not be affected by the same weather conditions that the destination is (which would be a reason to divert). Ft Lauderdale is 225nm away which is not far at all for a aircraft to divert to.

Landings in which the approach is entirely over water is tricky and is done with instruments all of the time, typically ILS. This is normal for commercial flights in general, but should the localizer lose the glideslope, autopilot on the b737 defaults to the last mode it was in, which for the approach, they may have been performing a flight level change (FLC) mode down to the airports elevation which will cause a decent more rapid than the 3% guild slope, which allows the aircraft to descend into and catch the glideslope localizer.[note 1] At some point the gluideslope was lost (or was never caught to begin with) which to the pilots’ surprise, they likely encountered a “terrain, pull up” notice and recovered before the situation got worse.

So why divert? Why not go around? Well they had to make that decision because they may not be able to divert if they made the decision to go around and try again due to fuel burn. They likely did not know why they captured the glideslope and then, all of a sudden, they were getting ready for a water landing. Was it the aircraft’s ILS or guideslope localized receiver? Due to the weather, they certainly could not do a visual approach, and there may not be sufficient RNAV points in the water on that approach to land there, so they diverted to an alternate where they know they could land visually if they absolutely had to.

Making decisions while flying aircraft is a calculated process and may not be immediately obvious. It’s easy to see in hindsight how things could have turned out differently but pilots often have minutes or seconds to make a decision and they will always choose the one that results in a safe landing over a convenient one. Media that doesn’t understand how these decisions are made love to poke fun at these silly pilots and it does a huge public disservice.

Note 1: this was explained to me from a friend who flew b737 for an airline

Going to eat my own foot here, but, as I see it, there are two different meanings of quantum in the brain.

1. Cells in the brain function quantum-ly. Honestly, most people shouldn't care about this, in the same way most people shouldn't care about the refractory period of neurons.

2. The brain simulates quantum calculations in situations of uncertainty, by bonding to/mirroring other people and the environment. This one everyone should care about.

How a group picks a leader, how people pick partners, important social decisions feel very quantum:

- uncertainty until they are suddenly resolved

- the "inside" view is different from the "outside" one

- spooky entanglement
What a strange article.

The obvious benefit of having a ram only vpn is eventually it will be shutdown or rebooted. An encrypted hard drive will have its data stored for practically the rest of time.

Nothing in this article tells me why Proton VPN is better than a Ram vpn.
That was plausibly a lone actor.

This was at least 4 different actors, perhaps 4 different groups of actors, executing a coordinated action simultaneously.
Nothing about climate change is particularly "intuitive" - you can't see or smell carbon dioxide, and understanding of physics enough to model the greenhouse effect took humanity quite awhile to achieve (though obviously you can stand in an actual greenhouse to get some idea).

But the Earth is a rather large place and making significant changes (I suppose we can argue over what constitutes significant) to its very atmosphere is a profound thing. We are not the first to do so obviously; the first photosynthesizers left their waste oxygen behind which was rather bad news for a lot of the other life on Earth prior to them. I would have hoped that collectively humans might have more agency than bacteria, but when you look at a chart of carbon dioxide in the atmosphere, it is hard to make that argument.
Forget the backlash. I'm pretty sure that Honda spent more than $6k per year for the cost of the people to run this, so they lost money on the operation before any reputation hit is accounted for.

That's essentially how mega.io works. The browser encrypts before upload, and the key is added to the download URL. When downloading, the browser uses the key in the URL for local decryption.

The intention is for them to have no access to or knowledge of file contents. Since the key is the URL, and URLs are generally sent to the server by the browser, Mega could (presumably) get the keys when someone follows the download link.

I believe removing the key from the URL still works, the site just prompts for it when needed, but that could also make its way to Mega if they ever decided they wanted it. It seems like a decent approach for ease of use, but has some weaknesses if security is the main goal. Encrypting separately before upload is still a very good idea if it matters for whatever reason.
The simultaneous move requests sound like Diplomacy. I'm not convinced this would improve the game in any way.
I don't think the site itself went down, so much as the scraping itself was excessive and beyond this, the presumed use of said scraping is against the TOS and copyrights of the site itself.

On a smaller site, it can absolutely be brutal. I worked on a site where literally 2/3 of requests were bots and a lot of those were dynamically constructed pages that are/were harder to cache. In the end, switching to a supplemental search database helped significantly, but it doesn't mean that an aggressive bot is an okay thing.
Large swaths of the south aren't really good for growing much. Very poor soil quality.
There needs to be a large pool of government-backed capital specifically for commercial to residential redevelopment and fast-track zoning approvals for this (somewhere along the line of City of Yes proposal in NYC).

Make it 4-5%, contingent upon (or give additional subsidies for) making significant percentage affordable rentals. Use the cash to cut the centers out of the building to daylight the large floor plates.

Residential rents for much more/ft than commercial so shouldn’t be a problem floating existing commercial mortgages. Maybe there’s even a program to borrow against the future higher stream of income to get non-performing loans current so these banks hold the existing paper instead of taking the write down.

If you try looking at the actual numbers or sketching rough tangent lines, you'll see that your "eyeballing" is misleading you. The graph is not at all linear -- the slope in recent decades is several times steeper than at the beginning of the time interval, as the accompanying caption says.

Perhaps you're looking at the graph on a phone screen, which compresses the scale and de-exaggerates the changes?

Very good point, you would have to make the decision yourself whether to offer shares for what type and length of service.

That’s interesting. I suppose having an “old bank” also affects things.

For example, some times in other situations my debit card also rejects big purchases or new countries or some reservations of funds from some new hotel when I check in. But because they are pretty modern they also have an app that notifies me of the rejection at the same time as the terminal is told that it was rejected and so I can go in to the app and say this is actually ok and then I try again and then it goes through.

Maybe what people need is really this kind of thing like what I have with my card and the app.
Like others say, usually just go for XGBoost, which is increasingly even shown (proven?) in literature, eg:

You can also start with scikit-learn's `LogisticRegressionCV`, if a linear model is more palatable to your audience.

The bigger challenge is to reliably estimate how good your model is.

It's not about getting the best performance – it's about getting the "real" performance. How will your model _really_ do on future unseen datasets?

The answer to this challenge is cross-validation. But what are the questions?

There are 2 very different questions for which the answer is cross-validation.

One is, which hyper parameters to use with your model?

The second is, what is the generalization performance of the model?

This requires 2 separate applications (loops) of cross-validation. The authors of this book talk about this in terms of having a "validation set" and a "test set" (Sometimes, these terms are switched around, and there is also "holdout set". It's critical to know how you, and the rest of your team, are using these terms in your modeling)

A robust way to implement these 2 CV's is with nested cross-validation, readily available in many packages – and also, should be "fast enough" using modern computers.

One exercise that remains is: with nested CV, which model do you pick as your "production" model?

That is also a bit tricky. Reading things like the following can help: https://stats.stackexchange.com/q/65128/207989

EDIT: for those inclined, here is a paper on why you need 2 loops of CV:

> At the same time, is it too much to ask for a sidewalk? That’s the thing that bothers me the most. Many suburbs seem built to be actively hostile to walkers, rather than just inconveniently sprawling.

No it is not, suburbs with sidewalks are better suburbs. They should all have them (on both sides) and it should be a code requirement.

But suburbs with a deficit of sidewalks are not "Horror Movie[s]," like these obnoxious urbanists, who are apparently creeped out by the existence of parking, want to propagandize them as.
Right, it gives me the key functionality of those systems in a way that’s decoupled from the base OS, so I can just run some version of Debian for five years or however long it’s got security updates, and not have to worry about things like services I want to run needing newer versions of lots of things than some old Debian has. Major version updates of my distro, or trying to get back ported newer packages in, have historically been the biggest single source of “fuck, now nothing works and there goes my weekend” running home servers, to the point of making ROI on them not so great and making me dread trying to add or update services I was running. This approach means I can install and run just about any service at any recent-ish version without touching the state of the OS itself. The underlying tech of docker isn’t directly important to me, nor any of the other features it provides, in this context, just that it’s separate from the base OS and gives me a way to “manage packages” and run services in that decoupled manner.

There is an opportunity cost to starting a new business. Depending on market and your experience it can take several years before you get anywhere close to earning the same level of income as a mid to senior level FAANG employee. There is also the time commitment to dealing with everything outside of being an IC (taxes, healthcare, finance, marketing, disputes, legal).

To anyone exploring starting a new business I would keep the day job and suffer until you get to a point where the business is on a good clip and you can dedicate all your time to it. Otherwise spending 20 years at FAANG and enjoying your life is really not a bad way to live, in fact its a dream to 99% of the planets population.
