Neural networks have become increasingly impressive in recent years, but there's a big catch: we don't really know what they are doing. We give them data and ways to get feedback, and somehow, they learn all kinds of tasks. It would be really useful, especially for safety purposes, to understand what they have learned and how they work after they've been trained. The ultimate goal is not only to understand in broad strokes what they're doing but to precisely reverse engineer the algorithms encoded in their parameters. This is the ambitious goal of mechanistic interpretability. As an introduction to this field, we show how researchers have been able to partly reverse-engineer how InceptionV1, a convolutional neural network, recognizes images.

Disclaimer: The hyperloop is an absolutely shit idea right now. I do not support building in any form right now.

Now to the shower thought: Theoretically, a hyperloop can get you from place A to place B on the planet in less than 40 min (back of the napkin calculations assuming constant acceleration and deceleration of around 1G). Being completely underground (more on that below), it would also be a really good piece of infrastructure safe from arial/orbital bombardment.

Now to the obvious problems: We need the tube to be very very straight to achieve high speeds without killing our passengers. We would want the hyperloop to enter city centers. Building such a straight thing in city centers would require a lot of demolition. Therefore, we would have to get it underground. Bringing it on the ground again outside cities doesn’t make sense because we would be introducing steep upward curves, thus reducing its maximum speed. Therefore, it makes sense to build this thing completely underground. Building underground also gives us many more benefits like not having to do much land acquisition, safety from violent attacks and so on.

Our tube would have to be incredibly airtight. It absolutely cannot have any leaks anywhere. Also, we need to be able to achieve incredibly low chamber pressures and maintain them.

If we are building this underground, we would need a shit load of energy to dig and transport the material outside the tunnel. We would also need a shit load of steel and other resources for these incredibly long tunnels.

Where do we get this energy? Where do we mine these resources without destroying the planet? Now this is where the “future” part comes in. We would need energy to be incredibly cheap. The only viable long term method (by “long term”, I mean it from the civilization time scale) would be via nuclear fusion. When is nuclear fusion happening? Well, it’s only 30 years away! /s Jokes aside, the energy source might be when nuclear fusion not only becomes possible, but also incredibly cheap (the nuclear reactor shouldn’t cost billions lol).

About the resources? Well, we probably need to mine them on the moon, no? The moon has A LOT of them right on the surface. If we can mine them and send them back home, we solve our resources problem!

Well, you might ask- doesn’t it make more sense to just have spaceships with engines propelled by nuclear fusion that exit the atmosphere, go at hypersonic speeds and then drop in? Why build expensive underground continent spanning tunnels? Well, what if we are attacked by aliens? They could easily blockade our airspace. Hell, just dropping a few million stealthy pebbles in our lower orbits would be enough to stop all hypersonic travel (the risk of ships exploding on contact with these pebbles would be too high for air travel to continue). Hypersonic spaceships would also face the problem of traditional aircrafts- you would need to build spaceports far from city centers. These spaceports would require a lot of space and cause a tremendous amount of noise pollution (constant sonic booms for every launch and landing).

Therefore, I think I have made my mind. I think I would be voting for a hyperloop proposal that possibly would be tabled in our direct democratic government a 100-150 years from now!

Most states rely on paper bureaucracy to ensure that the state can function and provide services. Paper bureaucracy has been part and parcel of how we maintain states and corporations since the Chinese invented the first paper bureaucracy systems of management 3000 years ago. But as you all probably know, bureaucracy kinda sucks. It costs a lot to maintain, and in the worst cases bureaucracy can turn a state into a labyrinthian monstrosity that can be near to impossible to navigate.

Estonia is a Baltic country that in recent years has been embarking on reform programs that are intended to change this. Estonia is a “Paperless state” meaning a state that has effectively removed all paper from it’s bureaucracy and replaced it with a digital state structure. In this short video I would like to introduce you to the digital state and argue for it.

Edit: To those downvoting, could please comment the reason as to why you are downvoting? The comments that are there right now do not explain the reason for the downvotes. I am genuinely curious as to what the thinking behind disliking the post is.

Imagine you are a trans woman in the 15th century. You lack the tech to grow boobs. You lack the tech to make ur dick into a vagina. However, the want still exists and is very real.

Now imagine the year is 2124. You are 55 years old. The tech to look exactly like you looked when you were sayyy 12 exists. You want to look like that. I would say that looking like that is your right. It's your body after all.

However, you are still 55 years old. You just LOOK like a child. But you possess the ability to consent. Is having sex with such people moral? (I would say it is).

This however introduces problems. How do you differentiate between actual children and people who physically look like children? Would this be a political issue then? Would adults who want to have sex with adults (but those who look like kids) be discriminated against? Would there be movements for this?

I really really don't understand how people are either so tiny brained or so fkin inconsiderate. Probably this is the wrong community to post this, as my infuriation levels are far from mild.

Like... you look up a tutorial on a specific thing. You see a list of videos describing the very thing that you want in perfect English. You open the video to see that it is in a completely different language (usually Hindi). You then feel like personally going on a mission to assassinate that video creator. /s

Like come on... I understand that English alphabets are more readable to people who speak languages other than English. FINE. I GET IT. But would it be too much to ask to at least put the name of the fkin language that your video is actually in, in the title?

Like... it would so much better for a video title to be "(Hindi) Ranked Retrieval model explained" instead of "Ranked Retrieval model explained" and it turning out to be in Hindi. Like... do these people not think? Or do they not have a brain? Or do they just not care?

I scoured through SO MANY VIDEOS and all of them have this nonsense going on. Like come on....

For those unaware, YaCy is an open source indexing software with some p2p search capabilities. However, if you've run it yourself, you'd know that the search results are very bad. Therefore I am wondering if this is a resources issue or a YaCy software issue, or both.

Had YaCy had really huge resources for the crawling and indexing, would it have been a good enough search engine to replace google/ddg?
