I consider Kerbal Space Program to be the most rewarding game I have ever played. Going into this page I was already somewhat familiar with many of the concepts it presented because I had encountered them during gameplay. However, having the ability to modify parameters was very helpful for visualizing different kinds of gravity assists. The game does not provide a way to do this, so it augments my understanding massively.

I agree that these interactive learning materials are incredibly promising towards actually understanding what is being presented. In other words, this is how I actually grok the concept.

That's called civil law and is used in almost all of Europe. Common law seems quite strange, nebulous and inefficient seen from a civil law continent.
> Just because a product is discontinued doesn't mean every component inside of it is also discontinued.

You're assuming the code doesn't have to be released as long as there exists something using it that isn't discontinued, but it can be the other way. As soon as you discontinue something, everything in it has to be released.

> Nor does it mean the restrictions on those are based in copyright. They may be restricted by other legal mechanisms other than copyright.

The proposal is a consumer protection law that requires source code to be published when a product goes out of support. If the law requires it to be released, you release it or you're in violation of the law.

The Magic of Solving Problems with 3D Printing
3D Printing has allowed me to be creative in ways I never thought possible. It has allowed me to create products that provide real value, products that didn’t exist before I designed them. On top of that, it’s satisfied my desire to ship products, even if the end-user is just me.
For me, the problem with YubiKeys is not the normal usage. That works great.

The problems are the "corner" cases: enrolling new keys, removing old keys, handling unintentional destruction of the key. The last one, in particular, is really problematic.

Some of the security mechanisms that a YubiKey provides are an extreme inconvenience. For example, I want to be able to clone my key via some mechanism in case it gets destroyed. I don't want to have to enroll 3 separate keys in every service on the planet just in case I put one in the wash accidentally. That's not possible with a YubiKey--for good reason--but it's a significant annoyance.

We consider "duplicating a physical key" such a common need that we have automated machines to do it at 7 Eleven. The fact that we don't have the same consideration of digital ones is problematic.

Dan Luu is missing the issue of food deserts. If you live in a food desert and you can’t afford a car then you’re not bringing home 50lb bags of beans and rice, you’re feeding yourself Doritos and instant noodles from the gas station convenience store. Never mind bringing home fresh meats and veggies!

Those are both more expensive and less healthy than cooking your own food.
While Blindsight and Echopraxia had some interesting world building and were both very readable books. It is worth mentioning the "science" part of them as science-fiction novels are essentially just a distillate of the most over-hyped pop-sci singularity-ism memes from the early 2000s era

A combination of "humans only use 1% of the brain" mythos married to a "super cognition unlocks emergent superpowers" results in something that's more accurately described as an unofficial entry in the Marvel cinematic universe than the hard-scifi it styles itself as.

Related personal story:

On January 6, 2023, at approximately noon, I happened to take a flight from Svolvær, Norway to Bodø, Norway, which, took me from 21.8 degrees latitude to 22.8 degrees latitude, which took me from [just inside polar night] to [just inside daytime].

I saw the moon at takeoff and the sun at landing.

It was an absolutely miraculous, specatular coincidence -- the latitudes I was flying over, the time, the date, the moon phase, the flight path.

This flight allowed me to have a full 3D view of space -- the moon, the Earth, the sun, all within an hour.

It was the first time I felt that the moon and sun weren't just discs flying around the sky randomly, but rather that I was the one flying through space, had a 3D sense of where the moon was behind me and where the sun was peeking ahead of me, and that the Earth felt curved as I moved out of the view of the moon and into the view of the sun.

...do is pop up a dimension, shear in that dimension, then project into your original dimension. This will make sense if we think of an example.

Say we're working in 2d and have a unit square starting at the origin and we want to translate it right by 1. This is not possible with any kind of matrix multiplication by a 2x2 matrix. That's easy to confirm if you just try it but trivially the lower right hand corner is on the origin and anything you multiply by zero is going to be zero. So any 2x2 matrix you multiply the coordinates of your square by is going to result in something where that point is still at the origin.

So instead what you do is pop your square up a dimension into 3D. So now you have a unit cube. If you do a shear of the unit cube by 1 in the x direction (which is a 3x3 matrix multiplication), you can take the projection ("shadow") of the top face of the cube to get back into 2D and you'll find it's where you wanted it (moved over by 1).

You could have a strong account password which is needed for remotely accessing the PC, and a simple PIN for convenience but which only works when authenticating locally.

(I'm assuming this is a personal PC and not a corporate device, in which case this model is the same but the strong password is also used for many internal single sign on resources).

Usually you pair this with a Windows Hello camera for face sign-in so you skip the logon hassle when in front of your PC.

There are settings in the group policy editor to change the Windows Hello PIN settings, but it could depend on your Windows edition and whether you have admin rights.

For example, if I use gpedit.msc > Computer Configuration > Administrative Templates > PIN Complexity, I see:

The moon is so interesting, easy to forget how much it affects life on Earth because we see it all the time.

Like others in the thread, I have a telescope and it's a wonderful experience pointing it skyward while it's still light out and the moon is visible. Then I can really see all the craters and "pock marks" on the surface. (My telescope isn't good enough to be able to see anything during a full moon, it all just becomes washed out.)

I see the management perspective. I’m just saying that perspective is obviously wrong if you have any stats knowledge.

If your point is just that management could have that knowledge and fail to apply it, I won’t argue with that. But I definitely wouldn’t call it “doing their best” when that happens.
I don't share that intuition. If I earn more money, I won't necessarily save more. I'll buy better food, better clothes, better everything and live a materially more prosperous life. My savings rate may even go down. Or up. It depends on the specifics. When a tech gets more efficient, it causes people to do more. To shape their surroundings and bend reality more to their will. If you can travel easier, you can realize your travel wishes better.

I am similarly irritated by loud vehicles and wonder why they are allowed to persist. Would this be better enforced if it didn't rely 100% on officer testimony? I wonder if there is a market for a "sound camera" that could be marketed to police departments. The idea would be that you point this thing at cars, like their radar gun, and it captures video, sound, and the # of decibels. Only thing I don't know is if there is a way to attribute particular sounds to particular objects found in the video. This would, potentially, give them the hard evidence to ticket these cases. If there is an easy way to make money off these, the police would be sure to enforce it.
Claude 70%. ChatGPT o1 for anything that needs more iterations, Cursor for local autocomplete, tested Gemini for concepts and it seemed solid. Replit when I want it to generate everything, from setting up a DB etc for any quick projects. But it’s a bit annoying and drives into a ditch a lot.

I honestly have to keep a tight rein on them all, so I usually ask for concepts first with no code, and need to iterate or start again a few times to get what I need. Get clear instructions, then generate. Drag in context, tight reins on changes I want. Make minor changes rather than wholesale.

Tricks I use. “Do you have any questions?” And “tell me what you want to do first.” Trigger it into the right latent space first, get the right neurons firing. Also “how else could I do this”. It’ll sometimes choose bad algo’s so you need to know your DSA, and it loves to overcomplicate. Tight reins :)

Claude’s personality is great. Just wants to help.

All work best on common languages and libraries. Edge cases or new versions get them confused. But you can paste in a new api and it’ll code against that perfectly.

I also use the API’s a lot, from cheap to pricy depending on task. Lots of data extraction, classifying. I got a (pricier model) data cleaner working on other data generated by a cheaper model, asking it to check eg 20 rows in each batch for consistency. Did a great job.

There are already US regulations on car noise,[0] and in more general circumstances,[1][2] but once it's purchased it can be altered by the owner, and then it's often up to local authorities to enforce local (and state[3]) noise by-laws.

This is the best statement of the problem. A lot of folks on this thread are importing the idea from computers or math that there is a _right answer_ to expressing laws in written language.

But this point of view ignores the vast diversity of human experience and variability that has to be governed using a few words. It is not the case that every possible edge and corner case can be anticipated ahead of time, and this would, in any event defeat the purpose of trying to make the law more clear.

Maybe laws can be written more clearly or more succinctly in some cases, but the specific words, phrases, grammar, etc. chosen matter quite a lot in a common law jurisdiction.

I'm saying that the world which passkey advocates want is a world where if, for any reason, you can't log in with your passkey (due to a lost/broken device, a software bug, whatever), you'll be locked out of your account. I'm saying that to contrast with my parent comment, which claims that the world passkey advocates want is one in which passkeys offer some slight convenience advantages but no security advantages because they'll be an alternative to passwords. Obviously they don't want the software bugs, but we know bugs happen.

Good luck arguing with the people who modify their motorcycles to be loud. The (nominal, though I suspect genuine for most) reason is to increase the likelihood that they are noticed by people driving cars.
Start with the desire - we want to have an algebra of 2D affine transformations with composition and (usually) inversion.

We can represent this with the trick of "homogeneous coordinates", using 3D vectors with the last entry 1 and 3x3 matrices with the last row [0, 0, 1].

This is convenient because both mathematicians and programmers are familiar with linear transforms and matrices. It's in the comfort zone. There are many libraries.

However, it's wasteful to store all those extra 1's and 0's in memory. You can always replace the matrices with

class Affine2D {
Matrix2x2 linear;
Vector2 shift;
};

and overload all the algebraic operators, including multiplication with 2D vectors.
