torchvision ResNet Updated 2025-07-16
pytorch.org/vision/0.13/models.html has a minimal runnable example adapted to python/pytorch/resnet_demo.py.
That example uses a ResNet pre-trained on the COCO dataset to do some inference, tested on Ubuntu 22.10:This first downloads the model, which is currently 167 MB.

./resnet_demo.py resnet_demo_in.jpg resnet_demo_out.jpgWe know it is COCO because of the docs: pytorch.org/vision/0.13/models/generated/torchvision.models.detection.fasterrcnn_resnet50_fpn_v2.html which explains that is an alias for:
FasterRCNN_ResNet50_FPN_V2_Weights.DEFAULTFasterRCNN_ResNet50_FPN_V2_Weights.COCO_V1After it finishes, the program prints the recognized classes:so we get the expected
['bird', 'banana']bird, but also the more intriguing banana.

Mitochondrial DNA mutates faster than nuclear DNA Updated 2025-07-16
Wikipedia mentions "Since animal mtDNA evolves faster than nuclear genetic markers" with a few sources.
Some sources:
- Power, Sex, Suicide by Nick Lane (2006) page 361 mentions:so this property is also important for the human mitochondrial molecular clock.
While nuclear DNA can barely distinguish between chimps and humans, the mitochondrial clock ticks fast enough to reveal differences accumulating over tens of thousands of years
- www.ncbi.nlm.nih.gov/pmc/articles/PMC3350313 says it for metazoans

How to blackout your window without drilling Swimming goggles plus sleeping mask hack Updated 2025-07-16
The problem with virtually all sleeping masks on the market is that they leave a lot of room near your nose for light to come in.
Ciro Santilli discovered a useful workaround for that: make the mask tighter with a swimming goggles!
Just make the goggles as loose as possible to not put pressure on your eyes, and then strap them over the sleeping mask.
If you are a back sleeper, put the googles forward as normal. If you are a stomach sleeper, put the googles on the back of your head, and the straps over the mask. This way you wont get your head squished by the goggles and the bed.
Once Ciro understood the idea, Googling "swimming googles sleeping mask" led to: mantasleep.uk/ might be a good option.

Total derivative Updated 2025-07-16
The total derivative of a function assigns for every point of the domain a linear map with same domain, which is the best linear approximation to the function value around this point, i.e. the tangent plane.

Topology Updated 2025-07-16
Just by havin the notion of neighbourhood, concepts such as limit and continuity can be defined without the need to specify a precise numerical value to the distance between two points with a metric.
As an example. consider the orthogonal group, which is also naturally a topological space. That group does not usually have a notion of distance defined for it by default. However, we can still talk about certain properties of it, e.g. that the orthogonal group is compact, and that the orthogonal group has two connected components.
