Ask HN: Swimming in space with quasi-rigid bodies
There is an mind blowing paper written in 2003 which explains how a quasi-rigid body can move on a curved manifold by undergoing changes in its shape.

http://groups.csail.mit.edu/mac/users/wisdom/swimming.pdf

There is a good discussion here:

https://physics.stackexchange.com/questions/886/swimming-in-spacetime-apparent-conserved-quantity-violation

My question: Is it possible to design a quasi-rigid body that could be used to escape Earth surface?

Many thanks!

Citation:
"For a quasi-rigid body to swim on a curved manifold, it must undergo changes in its shape. For such a change to result in a net rotation or translation of the body on the manifold, the shape changes must go through a nontrivial cycle of deformation.

A simple quasi-rigid body that satisfies these requirements is a body consisting of one mass point with mass m0 connected to two other mass points, each with mass m1, by geodesic struts of given length separated by a given angle. The body can be deformed by changing the length of the struts or the angle between them;

...
If the axis of the body is oriented radially away from the central mass, then the symmetry of the Schwarzschild geometry and the threefold symmetry of the swimmer guarantee that
any translation due to cyclic deformation will occur only in the radial direction. The problem is, then, to compute the radial component of the deformation field strength.

...
The curvature of spacetime is very slight,
so the ability to swim in spacetime is unlikely
to lead to new propulsion devices. For a
meter-sized object performing meter-sized
deformations at the surface of the Earth, the
displacement is of order 10⁻23 meters."
"Here on HN and all other platforms those that have a few such people have an advantage. How do you think every single piece of content they post gets massive upvotes and likes?"

Yeah, this is the key point. Voting rings etc. exists also here, but they are against the rules and are spotted and banned regulary.

So in general the pieces with the most upvotes are those where the majority of REAL people thinks they are interesting, like it should be. The same with genuine blogs, forums etc., those with INTERESTING content gets to the top. But if I encounter a blog with artificial engagement, I will just go away.

"Having said that… you also totally ignored my request to answer point by point the numbered points."

And why do you think I would feel obliged to do so, when you ignore my concrete criticism? You are creating lots of text defending the "ethics" of your buisness model, when in truth your buisness models depends on you keeping your twisted sense of ethics, no thank you to such a discussion.
Because you are not discussing in good faith.

"If ChatGPT generates an essay for you, or a homework assignment, that IS fake, sorry"

Because I was not talking about homework, but real code I write. That code works in the real world. Real value.
And the buisness description describes a real product and the content came from a real human, just the structuring of the words came with help. Framing this as cheating, so your own very shaddy things comes of as better, is just not something I will engage with any further.
This can't be bringing in much more than beer money, though, right?

There aren't many reviews, so I can't imagine too many people are buying these.
Your argument is valid in the context of people who just don't have any idea about User Experience. A popup can be made very user-friendly and non-obstructive if you plan it that way. A small slide-out from bottom-right corner with soft colors (in my opinion) is a great way to let people know you have a newsletter.

That's really weird and I have no idea why it wouldn't be working for you.

I even went as far as to spawn the ancient version of powershell included with Windows and pwsh 7.3.4 without a profile and tab completion adds the ampersand. I do import the PSReadLine module though in my profiles so maybe that is providing the functionality and I was wrong about loading an empty profile.
It’s less work to port it to a future machine that you don’t know the number and type of registers of yet.

If a future CPU has more registers than your VM, you have to either cripple your VM by not using all registers of the new hardware or write code to detect and remove register spilling that was necessary on the smaller architecture.

If, on the other hand, it has fewer or a different mix, you have to change your VM to add register spilling.

Either way, your byte code compiler has done register assignment work that it almost certainly has to discard once it starts running on the target architecture.

If you to start at the extreme end of “no registers”, you only ever have to handle the first case, and do that once and for all (sort-of. Things will be ‘a bit’ more complex in reality, certainly now that CPUs have vector registers, may have float8 or float16 hardware, etc)

You can also start at the extreme end of an infinite amount of registers. That’s what LLVM does. I think one reason that’s less popular with VMs because it makes it harder to get a proof of concept VM running on a system.
cs702, fantastic comment. I am sorta poking around this area too. I'd be curious what benchmark you're using to evaluate performance amongst these repos? If you're up for it, shoot me an email -- my email is in my profile.
that hypothetic argument depends on the ridiculous assumption that if a user won't convert within a minute or so, in the middle of the first piece of your content they've ever read, they never will
“Anglo-Saxon” is a bit of a broad term… you might describe Modern English as Mercian (an Anglian dialect), with lots of Saxon, Old Norse, and Old Norman influences. As well as other influences; I think those are the big ones.

Just to give an example of why “Anglo-Saxon” might be too broad a term—surviving Old English texts like Beowulf are in what you might call Late West Saxon, and the differences between Saxon and Anglian dialects help explain why Chaucer, who spoke something you might call Anglo-Norman, is much more accessible to modern readers.

If you want more of that Saxon influence, listen to West Country English, where it survives today.
Awesome! Very cool to see those professionals show such casual deep knowledge of their systems.

Makes me think it would be very cool if the aurora at this level were constant or at least consistent. We'd have effectively unlimited clean and easy power...
It seems like the title should mention that these books were largely written by ChatGPT or some other LLM.
Yeah, it is really hard to find something that can spin up a web app faster. Django is close, but rails is really good at it.
I stopped watching and blocked the linus channel (and may others) due to the faces.

But I guess I am only one and the many likes these faces for some reason.

It is also probably a failure of optimization where one started doing it and made a tiny bit more money than the other. Then the others had to do it to keep up, now all have the sucky faces and they all make the same amount as before while doing something they don't really like.
>For example, in work I regularly overhear O(2 minute) conversations in which co-workers talk about edge cases in our system that I didn't realize existed

Counterpoint: there are types which really like to insert themselves in every conversation or discussion. To the point it hampers not just their own work, but the work of everyone else. Taken to the extreme, they even create a state of helplessness in others, where these individuals become a funnel for all others to ask questions and obtain knowledge from. This is without accounting for all the noise pollution it creates.

Opponents are very eager to pull out these 'what about the office talks?' arguments, but whether the benefits even outweigh the downsides isn't obvious at all.

Heck, most developer work cultures use Scrum, and they can't even work through a single item on their retrospectives. Surely a bit of skepticism is warranted.
Oh, this browser again.

It seems that Firefox might have a problem with `mix-blend-mode: multiply;` and 3D CSS transforms.

Cards are now correctly behaving in Firefox, but across the board they are visually less appealing.

Thank you for bringing this up.
What percentage of people immediately bounce off your site as soon an aggravating interruption like this appears? I know I do. Have you measured if customers stay longer if you don't display the interruption?

Of that 6% how many actually read the newsletter as opposed to sending it to spam? Is that percentage more valuable to you than keeping people on the site?
The only one that I could see competing is Django, but IMO it isn't as fast as rails.

You're trusting the LLM a lot more than you should. It's entirely possible to skew those too. (Even ignoring the philosophical question of what an "unskewed" LLM would even be.) I'm actually impressed by OpenAI's efforts to do so. I also deplore them and think it's an atrocity, but I'm still impressed. The "As an AI language model" bit is just the obvious way they're skewed. I wouldn't trust an LLM any farther than I can throw it to accurately summarize anything important.

I guess not, but considering he can "write" 10 books a month, it might be worth it anyway...?
It’s a nice article, but I think it’s a little privileged as well. I’m only on my 40ies and I see a lot of it in myself. I was lucky enough to get to do some work that had a national impact in my early 30ies and I was well on my way to a career in management before I found out I didn’t really care about that. So I went back to programming, and still being fortunate, I’ve been able to find work at places that let me avoid too much project management and other things I dislike.

But that’s privileged, and while you may be fortunate enough to find yourself in those situations, or even in one where you can chose whether you want to retire or not, that’s not really how life is for most people. I’m not sure how this article will read for people who don’t have the choice. If I could only get jobs that requires a lot of time-management in Atlassian, or whatever PM tools you use to torture developers, I’d burn out, not because I didn’t know what motivated me but because I had to earn money by dealing with what was available to me. I imagine it’s even worse for people who aren’t in a line of work that is a buyers market.

I’m all aboard the “don’t let age stop you” thing that the article also preaches, and I hope you and I get to be lucky enough to live the life where we can continue doing what we like well into our retirement ages, but realistically, a lot of us won’t.
Apparently, judging from the sibling comments, such law doesn't even exist: the UK government "advised" the ISPs to "voluntarily" adopt such censorship on their own, or else the government would actually bother to draft and pass such a law.

These are the early days of paid search. Kagi laucnhed less than a year ago, after 25 years of humanity being "massaged" with the idea that it is OK for your searches (arguable both the most important and most intimate thing you do online) to be paid by someone else, an unknown 3rd party, usually an advertiser.

The early resistance towards a paid model is to be expected. But if we can learn from the example of YouTube Premium (25M+ subscribers for a product available for free), there are millions of people ready to pay for search today, we just haven't reached them.
I'll go with a "what brought you here".

I find this is the basic of networking hack. And this is what most people do. Say "hi" and ask their opinion or their story.

Or you can offer your opinion "I found that new technique very interesting". "I didn't understand why that's better than X".

Or if you're super focused on something specific go for that. You're looking for a job, a client, an employee, ask for that directly. "Hi, I really enjoyed the talk and I'm looking for a job in the area. Are you working on something similar?".

Pebble had a small but vocal audience. Their audience is price conscious, picky about features being exactly what they want, and relatively hard to please (despite the simplicity of their expectations).

It’s not a good recipe for building a company around. Probably best for someone doing a hobby-scale or deliberately small business, but establishing manufacturing and logistics for a hardware project is notoriously expensive.

Meanwhile, engineer compensation expectations have gone up a lot since the Pebble days. Just think about how many Pebble watches you’d have to sell to be able to support even one engineer salary. Multiple that across a team big enough to do everything needed to ship a Pebble watch that satisfies their audience and it’s not hard to see why it’s not happening.
You can use a privacy-focused VPN like Mullvad to conceal your identity from the search engine. In most markets having a credit/debit card requires personal information so there's nothing you can do if they don't provide a privacy-friendly payment alternative.

Anyway, GP's question was simply:

"Can I use Kagi without linking any real-world identifiers (including credit card details) to my search queries in any way?"

And the correct answer is no.
But this is vacuous and unrelated to the halting problem or Rice's Thm. A program that emits "Yes" on every input will decide some property of programs with zero false negatives.
> task is presented in context of social relations (or more broadly "evolutionarily familiar problems"), people tend to get it immediatelly, or rather intuitivelly. Bonkers, right?

That's obvious, not bonkers - if you have experience in some class of problems, it's easier to solve the same kind of problem, the patterns match in your head, so the solution pattern is used right away.
Just like you can solve these numeric problems quickly if you're trained on them

Even if you are in the EU, 1-2 weeks notice for something like that is bonkers. And as soon as company has more than a handful of employees, this is something you want to have booked with hotel and such earlier anyways. From what I've seen in other companies, time and location of such things gets announced months in advance.

I Can Finish Final Space
Not sure if this is HN appropriate, but I wanted to spread the word that Olan Rogers got the go-ahead to finish the final season of Final Space as a comic book.

Originally it was one of the first animated shows to be cancelled by Warner Bros before all the other animated shows got pulled as well. As a die-hard fan of the show, I am really enthusiastic about this getting the ending it deserves!
Really hope this doesn't affect their development of VirtIO drivers and related virtualization technology. Although being realistic, it probably will.
I am sure there are legitimate people out there doing life coaching as a real job, and provide real value. I've met a few of them - mainly retirees who have spent a long time in the corporate sector C-Suite or as successful entrepreneurs who have made enough money and just want to help others. There's one who I engage with maybe once or twice a year who is a trained psychologist who spent a long time as a C-suite exec. All I do with him is talk through a business problem, and he generally can simplify what I need to do or why I'm feeling a certain way about a given business-related issue or how it's affecting my personal life.

The problem is, if you look on LinkedIn, most life coaches are not anything besides flavor-of-the-month grifters without legitimate experience. Since what a "life coach" is, is so vaguely defined, anyone can claim to be one without much pushback or certifiable training....my aunt is one - she has no training and just gives out advice based on what she reads on the internet (yikes!). Yet people have gone to her in the past for advice she's not even remotely qualified to give.

Real life coaching requires highly-customized and individualized advice depending on the situation a given person is in and what they are trying to achieve.

The fact that people who are actively seeking help or advice at practically any stage of life are susceptible to bullshit in hopes that it might help them is where things get a little worrying.

Yes, the claim is self-referential in the sense that it describes a certain attitude towards truth and how that attitude can affect one’s openness to new information. Specifically, the claim suggests that individuals who are not interested in truth because it conflicts with their existing beliefs are unlikely to change their minds even when presented with evidence or information that contradicts their views. This can create a self-reinforcing cycle where the individual becomes increasingly resistant to new ideas and perspectives.

Mutexes are implemented with (among other) cmpxchg instructions under the hood. It’s sort of a false dichotomy to divide the world into locks and cmpxchgs. Also inconsistent to claim they are slow but uncontended mutexes are fast. It is certainly true that you can write slower and harder to understand algorithms using atomic primitives instead of mutexes.
I think it shows that we suck at generalization. Even though the task is the same, we are not able to see the same pattern in an arbitrary framing of the same problem. Beaming directly might help.

Does the prescription come with magical CO2 scrubbers?

All the prescription does is set some baseline parameters. Most CPAPs you can buy are APAPs anyway and modify the parameters on the fly.

No problem, easy to skim by it!

In terms of how this reduces artifact size: Go statically compiles everything, and the majority of that weight is from dependencies. Compiling into three different binaries would:

1. Increase build time, because even while the dependencies are cached from each subsequent build, linking isn't free. Takes about 20s to link each binary, so it adds about 40s+ to the build to create them twice.

2. Increases build size, because each binary is about 150MB, so we go from 150 -> 450MB, which increases time to upload to container registry and download into the infrastructure that runs things.

In answer to the security surface, the code between cron/worker/web is very interlinked. There would be little practical reduction in surface area from splitting the binary, though perhaps for some applications there might.
Thank you!

You'll see that type of output from most WYSYWIG editors. Some are better than others and they've improved over time, but a lot are still garbage. Both Redactor and TinyMCE would have produced something like this at points in the past (been a while since I used them, so that may not be the case now). Pasting from MS Word will also produce some gnarly HTML in most editors.
Saying you aren’t a trust fund baby therefore you aren’t rich is just plain silly.
Ask HN: How do you manage time and execute your plans?
Hi HNers, I'm interested in hearing about how you execute your everyday plans. While I believe that planning ahead is a useful approach for a productive life, personally for me, putting it into practice is very challenging.

So, I'm curious to know:

What's your personal approach for managing your time and executing your plans?

How do you ensure that you stay on track and achieve your goals?

Any tips or tricks you'd like to share?
