Testing Ubuntu 20 on old laptop

So I wanted to test Ubuntu 20 on old laptop I have and see if things will work. To my surprise, it does. It's not as swift as on new laptop, but considering the age (9 years?), it still works. There are no issues with drivers and everything works smoothly. Ubuntu 20.04  running on Lenovo X220 The only recommendation I would have is to allow different scale for different displays, but this can be achieved with choosing different resolutions. Little confusing, but at the end it works. One more thing - does it really need to use 1.3 GB of memory without running anything? For old systems this might be a little bit of issue.

Good phones for good price (399$)

It's nice that Apple & Google decided to make some lower end (price), but good phones: Apple iPhone SE Google Pixel 3a Or if you want really cheap (99$), you can go for Nokia: Nokia 3.1

Exact Match Convolution

So, I tried to test out exact match convolution, which can be defined as: It consists from three parts: pixel offset standard convolution convolution bias If you test it out with DeeperThought , with config: convolutionsq,1,28,28,500,8,8,0.0,1.0,-0.001 max,500,21,21,21,21 matrix,500,200,0.1,-0.001 sigmoid,200 dropout,200,0.5 matrix,200,10,0.1,-0.001 softmax,10 where convolutionsq is exact match convolution (emc), you get pretty good results: Top accuracy on test data: 98.68 % (Dataset - MNIST digits). Not as good as with convolution (up to 99.41 % accuracy), but pretty close. Are we really just looking for exact matches and we do so by convolution?

Maybe office spaces can use this overnight?

Far-UVC Light Safely Kills Airborne Coronaviruses Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses This reminds me of water purifier using UV filter for hiking. The only issue I had with it (when used in past), it would not turn on when used in water in mountains (it worked at home on tap water just fine though). Found on reddit .
