The biome button graphics are taken from the OpenTTD main menu.

New comment by hulium in "The MacBook has a sensor that knows the exact angle of the screen hinge"

Other laptops have this too. Linux has a driver for it.

https://www.phoronix.com/news/Intel-Hinge-Driver-Linux-5.12

The sensor angle would be in a file like `/sys/bus/iio/devices/iio:device*/in_angl0_raw` (device number can vary). At least I have this in a config file and remember it working (maybe on a different computer?). I cannot get it to work anymore on my laptop.

The part about low-pass filtering using FFT ends with the conclusion that it is fundamentally a different thing from a gaussian blur ("Low Pass Filter ≠ Low Pass Filter"). However: A convolution in image space is just a multiplication in fourier space. If you multiplied with a gaussian in fourier space you should get a gaussian blur. It's just not necessarily the fastest option.

I am not surprised that the sentence existed once. But "Wikipedia once said this during the time August 2024-Februrary 2025" is not the same as "Source: Wikipedia" because of the way Wikipedia evolves. It's especially bad if you disregard the entire much more nuanced discussion in the remaining article.

I think Finland just has a large enough extent from south to north that solar might be starting to become viable in the south but not in the north. While Iceland already produces more electricity per capita than any other country, using only hydro and geothermal, so solar is pretty much non-existent.

That's a fake Wikipedia screenshot! That line doesn't exist in the actual article and didn't at the time when that tweet was written, and does not even fit in the context. To me, this is at best an example for how much higher the quality is on Wikipedia than in average social media like X.

Certainly not the only country. Iceland is even more extreme in this regard and unlike Finland it is powered by 100% renewables, hydro and geothermal energy. In Finland the only good renewable alternative is wood/biomass.

During play, yes, obviously you need an implementation of the game to play it. But in its planning tree, no:

> MuZero only masks legal actions at the root of the search tree where the environment can be queried, but does not perform any masking within the search tree. This is possible because the network rapidly learns not to predict actions that never occur in the trajectories it is trained on.

It was essentially banned via copyright for a long time. The only reason that it is available now is that 70 years have passed since the authors death.

It seems like the screenshots are clustered in some way. That is especially visible when you zoom out.

Seems more like it should stop the AI from e.g. summarizing news and emails about death, not for a chat filter.

It uses a bit simpler approach, only detecting movement, but it works good enough for such games.

New comment by hulium in "The longest train journey is epic – but nobody's ever taken it"

hulium — Sat, 17 May 2025 18:23:04 +0000

Before 2022, I once noticed that the Deutsche Bahn app for German trains let me put Pyongyang, the capital of North Korea, as destination. The app is good at finding international connections, but it only shows stations that are actually reachable from Germany. After some research, I found it was indeed possible to find a connection from Europe to Pyongyang via Vladivostok once per month. Not anymore though, they removed the Russian train network from their system.

That's the point, the linked system prompt explicitly tells it that Trump was elected.

New comment by hulium in "Pixel is a unit of length and area"

hulium — Wed, 23 Apr 2025 17:40:13 +0000

The users may have 1080p monitors, but even Windows does not do subpixel antialiasing in its new apps (UWP/WinUI) anymore. On Linux, GTK4 does not do subpixel antialiasing anymore.

The reason is mostly that it is too hard to make it work under transformations and compositing, while higher resolution screens are a better solution for anyone who cares enough.

I think almost all of those criticisms are solved in newer versions of Pascal.

The first line is already nonsense. The answer is obviously not "room".

Getting the correct final answer tells you nothing about the reasoning. The LLM will solve the puzzle even if you only pass it the sentence "the [] de Milo is discovered by a Greek []".

He has written a program:

https://github.com/brunopostle/piranesi

The problem is that it is a method for projecting a rectangle, not a full 3D scene. I can imagine though that it could be extended to a full projection if you specify a central axis along which the perspective trick happens.

Can you say more about what these small mistakes were? Would they affect the interpretation of the law?

> by that logic everyone is native african

No that does not follow, but the very first individuals who migrated to America (the humans this discussion is about) obviously were not born in America. By my logic there were no native Americans that came from Asia to America, but their descendants became native.

Yes I know, very pedantic. I don't think there is anything wrong with the title.
