Thinking of a modern GPU as a “graphics processor” is a bit misleading. GPUs haven’t been purely graphics processors for 15 years or so, they’ve morphed into general-purpose parallel compute processors with a few graphics-specific things implemented in hardware as separate components (e.g. rasterization, fragment blending).
Those hardware stages generally take so little time compared to the rest of the graphics pipeline that it normally makes the most sense to have far more silicon dedicated to general-purpose shader cores than the fixed-function graphics hardware. A single rasterizer unit might be able to produce up to 16 shader threads worth of fragments per cycle, so even if your fragment shader is very simple and only takes 8 cycles per pixel, you can keep 8x16 cores busy with only one rasterizer in this example.
The result is that GPUs are basically just a chip packed full of a staggering number of fully programmable floating-point and integer ALUs, with only a little bit of fixed hardware dedicated to graphics squeezed in between. Any application which doesn’t need the graphics stuff and just wants to run a program on thousands of threads in parallel can simply ignore the graphics hardware and stick to the programmable shader cores, and still be able to leverage nearly all of the chip’s computational power. Heck, a growing number of games are bypassing the fixed-function hardware for some parts of rendering (e.g. compositing with compute shaders instead of drawing screen-sized rectangles, etc.) because it’s faster to simply start a bunch of threads and read+write a bunch of pixels in software.

The “B” in “Boot” looks really off, the inside of the big “O” is lighter than the rest of the sign, and the kerning on the bottom text is all over the place.

I have a blanket I’ve slept with every day since I was barely a month old (am 23 now), wouldn’t trade it for anything. I can definitely relate :)

Additionally, it is known that cows are mammals. Therefore, by transitivity, we can show that coconuts are mammals. QED.

Okay, I can’t speak for this extremely fucked up example, but in general it’s very simple:
- see shape which sufficiently resembles (partially) naked woman, maybe in suggestive pose
- neuron activation
- you are now horny
There is no need to imagine any fucking, seeing the image is enough to get you into the mood, looking at it long enough (or at different images for long enough) will get you most of the way there, and the hand can take care of the rest

To be fair, for most of those other mediums don’t need as much time to consume. An old song takes a few minutes to listen to and a movie can be watched in a couple hours, but I have played thousands of hours of Minecraft (and will continue playing it for the foreseeable future).

I think there are definitely some specific cases where it makes sense. For example garbage dumps (and compost facilities as well, I think) produce tons of methane and other unpleasant flammable gases which often get flared off, it seems only reasonable that if you’re gonna be burning the gas anyway that you might as well use that heat to spin a turbine instead of just fuelling a uselessly burning flame on a pole.
In theory biofuel is perfectly carbon-neutral if you’re growing all the input biomass yourself, since all the carbon released when the fuel is burned is carbon which was captured during the growth stage. But in practice it’s not ideal:
- There’s still plenty of potential sources of emissions, like harvesting and transporting the biomass will likely be burning fossil fuels and also tires and stuff
- Growing biomass is slow, so from what I understand a lot of it ends up coming from newly cut trees and stuff because it’s cheaper than buying tons of land, planting stuff and then waiting years for stuff to grow
- IMO the main problem: there are other more useful things we could be doing with that land, if you can grow crops for biofuel production you could also just grow food there and put some wind turbines or solar panels or something on one of the many places on earth not suitable for agriculture to provide the energy
If the biofuel is being produced from like agricultural byproducts (e.g. the stalks of harvested crops) I don’t think there’s really a problem, but AFAIK most of that stuff gets used for compost or gets left on fields to put nutrients back in the soil (and because it’s cheaper and easier to leave it than having to collect it again).

My confusion isn’t why they’re decorated, but why the decoration is always on the downwards facing side so you can’t actually see it once installed.

I’ve never understood this about GPUs, why are they all designed so that the cool-looking decorated part with the fancy heat spreader and fans and LEDs and stuff are facing downwards?
