Time

Read about how to use the time module in www.realpython.com. You can use time in a decorator or create a Time class to instantiate a start of a timer and an end of a timer. Decorators are quite onerous but useful. I wonder if there could be a use for a decorator in recursion? Recursion still boggles my mind if you don't take in consideration of the unwrapping from the stack of the function leading to a base case. Also I never realized that data structures could be recursive like lists and dictionaries. That you can apply recursion with python lists is really fascinating. I am at a loss of a direct use case just the same with coroutines but nevertheless interesting.

Knowing how to pivot is important in OSINT it seems and to go from a wide scope to a narrower scope. Pivot charts are useful to collect information of results from selectors, each pivot being a resultant node of information. Going from a wide search to a narrower search is like the goldilock's effect, a little too wide and you lose focus but too focused you can lose out on other wider details. All sources state that methdology trumps tools and the focus early on in an OSINT career is to develop your methodology like knowing how to pivot and knowing the intelligence cycle. Being nimble and flexible in your search queries is important to hone your searches using Google as a primary tool to locate information. You just have to Google it. You Google to find tools like websites that facilitate investigations. It seems that Rae Baker, the author of Deep Dive into OSINT, is adept at using Google to serve her needs though she stresses the importance of methodology. Cynthia Hetherington of ...

Being in California I have seen plaques from the native sons of the golden west and thought nothing about them at the Burlingame train station. They seemed like a benign fraternity but if you dig a little deeper into their history you realize they were like California's KKK chapter against the Japanese. They really hated the Japanese and wanted to expel them from California as if the Japanese were vermin in the early 20th century. Native sons of the golden west go way back into the 1800's and their anti-japanese stance existed at the moment it seems that Japanese immigrants arrived in the late 1800's. They wanted to end birth right citizenship for Japanese Americans who were born in America. This echoes today with Republicans questioning birth right citizenship and considering getting rid of it. The hostilities towards Japanese immigrants resonants today with the attack on the newly arrived Latinx immigrants. The zenophobia is always an old trope that seems to never end wit...

My learning methods are flawed. I am not doing spaced retrieval exercises which is supposedly the most effective means of learning. Spacing out what you retrieve from memory of your reading is time tested the best way. I tend to read and reread which is ineffective and I don't force myself to sit away from the text and try to remember everything I have just read. It is like dyeing cloth. You dip the cloth in the dye over and over again and the coloration gets more and more saturated and radiant. Spacing the time you remember what you have learned repeatedly ,spaced repetition, is important and I have to practice this more.
