Online Color Blindness Simulator | DaltonLens
This page lets you simulate various color vision deficiencies (CVD) directly in your browser. There are many simulation methods, with varying degrees of accuracy. Several are proposed here and they all have been carefully implemented in DaltonLens-Python by reviewing the state-of-the-art and testing them against reference implementations.Mon 29 Aug 2022 02:40:32 PM +08 - permalink -- https://daltonlens.org/colorblindness-simulator

How Earth’s Climate Changes Naturally (and Why Things Are Different Now) | Quanta Magazine
Earth has been a snowball and a hothouse at different times in its past. So if the climate changed before humans, how can we be sure we’re responsible for the dramatic warming that’s happening today?Wed 22 Jul 2020 02:36:07 PM +08 - permalink -
In part it’s because we can clearly show the causal link between carbon dioxide emissions from human activity and the 1.28 degree Celsius (and rising) global temperature increase since preindustrial times.
But paleoclimatologists have also made great strides in understanding the processes that drove climate change in Earth’s past. Here’s a primer on 10 ways climate varies naturally, and how each compares with what’s happening now.- https://www.quantamagazine.org/how-earths-climate-changes-naturally-and-why-things-are-different-now-20200721/

The Art of Command Line in one page · jlevy/the-art-of-command-line
Fluency on the command line is a skill often neglected or considered arcane, but it improves your flexibility and productivity as an engineer in both obvious and subtle ways. This is a selection of notes and tips on using the command-line that we've found useful when working on Linux. Some tips are elementary, and some are fairly specific, sophisticated, or obscure. This page is not long, but if you can use and recall all the items here, you know a lot.Tue 24 Mar 2020 07:32:13 AM +08 - permalink -- https://github.com/jlevy/the-art-of-command-line/blob/master/README.md

NASA Worldview
This app from NASA's EOSDIS provides the capability to interactively browse over 600 global, full-resolution satellite imagery layers on desktop and mobile devices. Many of the imagery layers are updated within three hours of observation, showing the entire Earth as it is "right now". This supports time-critical applications such as wildfire management, air quality measurements, and flood monitoring. Some satellite imagery layers span almost 30 years, providing a long term view of our dynamic planet. The underlying data is available for download, and Arctic and Antarctic views of several imagery layers are available for a “full globe” perspective.Mon 21 May 2018 05:43:28 AM +08 - permalink -- https://worldview.earthdata.nasa.gov/
