Copying here an interesting comment on the video from user @melkiorwiseman -
Fun Fact: The first step-by-step switch and indeed the very first automatic telephone exchange was invented by Almon Strowger.
Almon Strowger was an undertaker by trade. He became convinced that the manual telephone exchange operator, who was the daughter of the only other undertaker in town, was deliberately directing all calls for "the undertaker" to her father's practice instead of dividing them equally between the two as was standard practice at the time.
Strowger decided that he needed to invent a way for telephone customers to dial the number themselves and used cut out pieces of paper to represent the electrical contacts so that he could work out how the equipment should work.
If I remember correctly, Strowger was granted a patent for his automatic telephone exchange in 1929.
Strowger's exchange required two extra wires from the exchange to each telephone to carry the dialling signals, but some clever lateral thinking allowed for using the same two wires for nearly all signalling as well as for speech.
Well said. Similar to you, I code now almost exclusively in Flask. I don't want to spend days and night learning (and remembering for interviews) unnecessary abstractions and apis. Instead I prefer to spend more time on CS fundamentals, if I have to.
Sad part of this story is broken hiring. Your resume doesn't get short-listed unless it comes with new hyped-shiny-toy. But this can encourage you to put more efforts on finding good employer.
Apart from juggling act you mentioned, there is another caveat. Many devs don't understand exact use-cases of these design patterns and use them in wrong context.
On foot note, If you don't have good team of engineers similar to OP, best way to craft your art is -
- pick up a good library in your subject
- start copying it line by line
- when copying, try to understand everything
- this will teach you lot about designing softwares
Even though this sounds like stupid and time consuming, it is not. Believe me. You don't have to even reach 100 %, just try to reach 33 %. You will learn lot by this in short period.
To get math intuition, you need some memorization along with practice. In school, you focus lot on remembering things for exams, that pays off later. As you grow, it becomes difficult to remember mindlessly.
1. Do exercises from competitive-exam books written for secondary school children.
2. Try to solve as many as possible exam papers in stipulated time.
This will help you to build intuition. Intuition comes only after doing something for long time (unless you are born-genius). Memorization plays very important role in learning maths, language, music instruments. On second note, don't fear to change resources if you're not comfortable. What I mean is - in childhood if you like teacher, you excel in subject. So you have to find material which match your temperament. Wish you best luck !
