Things I have learned

Making sauerkraut is easy. I typically use organic cabbages, pickling or kosher salt and dried juniper berries for my sauerkraut. So lets get started. I have a fermentation pot with weights, a lid, and a moat like rim that is airtight once the lid is placed inside the moat and the moat is filled with water. I have read a bunch of recipes that use different equipment and I am sure they work equally well. I did make a few times sauerkraut in a Korean onggi pot without a moat rim and it worked for me. Before I start filling the fermentation pot with cabbage, I rinse the pot interior twice with boiling water to disinfect everything. I also fill the inner portion of the lid with boiling water and sub-merge the two half-weights in boiling water as well. My 5-liter fermentation pot. Please note the moat at the top rim. The lid is placed into the moat and then the moat is filled with water. Once the moat is filled with water the content inside is sealed off. The lid and the two ha...

Now lets continue with some items I actually learned when looking at color specific things in more detail. Some Physical Properties of the Eye The human eye has typically 3 different daylight-sensitive cells (also called cone-cells). The sensitivity of each type of cone-cell type peaks at a different wave-length. The blue sensitive cone-cells peak in the blue wavelength of the light spectrum, the red sensitive cone-cells peak in the red wavelength of the light spectrum, and the green sensitive cone-cells peak in the green wavelength of the light spectrum. Qualitative Diagram of the Light-Sensitivity versus Light-Wavelength of the 3 different Cells Basically the brain constructs a color perception when processing the combination of responses from all 3 cone-cell types (there are lots of cone-cells, each triple responsible for a tiny fraction of the vision field an eye sees. And there are normally 2 eyes, so there is plenty of vision processing going on in the brain and t...

In early 2013 I decided to dig a bit into how to use color in presentation slides and data-visualizations (online and offline) better. I always had a passing interest in visualizing data. Early on such data visualization involved the use of Excel spreadsheets (and sometimes a sprinkle of Visual Basic programming to automate the spreadsheets somewhat). But I also had a need to use color at time in PowerPoint presentation slides for one purpose or the other. We are talking roughly about the 1998 to 2003 time frame. From 2003 onward I also encountered color considerations for more and more web-pages of mine that again visualized all sorts of information. It is fair to say that I did read a number of books related to visualization of documents and presentation slides during the whole time. These books dealt mostly with design principles/considerations for page layouts, font types, size of fonts, and images. Book examples would be the "Non-Designer's Design Book" from Robin Wi...
