Why would I write a post highlighting tech blogs? My main position in the Jane book, there are 40W+ words, there are always small friends background private letter to me, ask me what can insist on writing so many articles, what is the secret? Now words very much, but these are an article on an accumulation of at ordinary times, I also feel that before writing articles like heart, heavy in my heart, as working why must want to write, but I know that after you’ve written the carefree feeling, and this is my technology the footprints of life, it makes my life isn’t like water, quietly slip away and leaf don’t stick, But into an eternal, never forgotten past

Here I would like to elaborate on the necessity of writing a technical blog from a few scheduling, do not like the little friends please mercy, this article technical theory source:

  • How do you put 100 books you’ve read into your head in a really systematic way

What the brain looks like

Since the advent of automatic computers, people have always compared computers to their brains because of the similarities in words and behaviors. This is based on the subconscious recognition of similarity, which is actually true most of the time. Computers are really similar to brains

The cognition of computer can be looked at like this:

Computer is the host processing information, power supply, power supply will be insufficient CPU frequency, reduce performance

So how do we fit the corresponding brain on a computer?

  • The body is the power source
  • The brain is the mainframe

1. Your body is your power source

According to the analysis of the brain model, the computational limit capacity of human brain is far beyond the present performance of human brain. The general development level of human brain is as follows :2%-4%,4% are geniuses with exceptional brains, 3% are usually very smart people, and 2% are normal people. The reason for this is that the human body, in order to last long, restricts energy supply to very poor levels in order to extend the body’s working cycle as long as possible. If the brain is running at full power, one minute is enough to drain the human body dry, and the heat released is enough to eat the monkey feast, so where is the bottleneck of human function

2. The brain is the mainframe

Including part of the perception of the original, memory, hard disk, processor, cooling components, specific we imagine… CPU, hard disk what needless to say we can also imagine, here I say the next memory:

I believe that the human brain has not one set of memory, but three sets of memory: one is to temporarily store the data transmitted by the senses and processed, data invalidation is very short, memory erasure is fast; 1 set is to store the day after learning, sorting out, or very impressive data, timeliness for the day, and deep sleep to sort out, effective content transferred to the hard disk, erasable slow; 1 set is for the subconscious mind to use, recording the very bright points observed by the subconscious mind, also with deep sleep to sort out, erase

Brain data storage structures

This basic can set ready-made data structure, we as a physical thing to store data, there is also a data structure (please forgive me do not understand the principle of the hard disk). There have been many authoritative studies on this, such as the article I listed at the beginning, which simply says that the brain stores data in a lattice mechanism

  • Dots are the most distinctive features of things that have been extracted, nouns and actions in modern language structures that have been constantly evolving through human society, such as: Watches, cars, dogs, cats, these things the understanding of the kind of first of all, based on the characteristics of fixed points in the brain as the forerunner, the point of these layers of associative and cohesion to the next point, everyone looked at what like this: list bai, each knowledge system or characteristics of the system has their own list, the list of the main body of cognition, memory structure and the backbone network. In addition, the structure of neurons in the human brain is naturally close to the data structure of linked lists, which can be said to be determined by biological characteristics

  • Matrix – this is easy to understand, is your code in the data class

class Book{
  var price;
  var name = "AA";
  var tag = "AA";
  var color = "red";
}
Copy the code

This is how data is stored in the brain, so how is one thing stored? It is to recall the features of an event, and then find all the data objects of the event through the layers of links of some feature points, and finally piece together and restore the whole cognition. Often we can only recall parts of it because it’s something that we don’t think is important enough to store or that we can’t store efficiently

The above is my rough understanding, the key is to highlight the lattice understanding for the following

Sleep learning

Japanese anime has teased this sleep learning method many times. The essence of sleep learning method is to systematically study, organize and analyze the data stored in temporary memory during the day and write them into hard disk according to their feature points, which is deep in the brain, and then erase this memory for tomorrow’s use

So there is a saying: poor sleep memory is poor, you can learn yesterday because of the quality of sleep or the length of the reason is not processed directly erase and not written into the brain, can not remember, in fact, it is not not remembered, you did not write, directly erase…

Watch your body clock. You can’t beat it, at least not me.

The process of knowledge learning

Estimated friends especially when learning new knowledge new knowledge field, knowledge block are very large head, this is we use biological computing performance, the brain it’s biological computer will according to our usual training model of learning to learn, parsing, if can successfully extract the characteristic is to understand it. At this time, the vast majority of people think they have learned, and then go to do other things, but they do not know that the human body in deep sleep will sort out what they have learned that day, and according to the brain analysis, extraction results, according to the feature points to store what they have learned one by one

Generally such a 2 hours come over, a lot of people will certainly head distension, serious will partial headache, this shows what, that nutrition can not keep up, the slow. People always say that old age, more energy, what is energy: is your brain can continue to run, energy is the fundamental of the body function, so we should exercise lazy, good maintenance of the body is the capital of learning. You’re in great shape, and you’ll learn faster than a weakling…

That’s the average person learning, and then it’s gone. After a few days, you’ll hear:

  • Oh, I just can't remember what I learned two days ago!
  • I've seen this word a lot, but what does it mean
  • This question has clearly written before ah, how to answer
  • I'll remember, wait a minute, ah, how can't remember... Ah, I know, I know

That everyone goes through it, is what, according to my research, before the study, analysis of incomplete, only do the surface, not really clear, relevant feature points, logic has some confusion, not clear, when deep sleep so these entanglements of cognition is not classified storage, the brain is likely to be stored in them close but not the right place, Or just throw it away because it’s too messy to make sense of. When we are in accordance with the relevant characteristics, logic in the brain according to the linked list data structure to search the data, because the data is not in the correct position, or simply does not exist, so I can’t think of it, or very close to name the feeling, is the unexpected, such as the brain while expanding the scope of the search will find the answer, it is because we didn’t really finished learning, cognitive process

For example, it’s like the last kilometer of logistics, the last kilometer of services, the last kilometer of connections. It was this last mile that was missing

Here’s my summary of how the brain learns:

  • Chop 1.– Act like a shredder and try to break the input into comprehensible chunks based on your knowledge structure and previous experience
  • 2. The wall– Continue to break down the above pieces of knowledge like a wall breaker, breaking them down into the smallest points we can understand, and then summarize the logical connections
  • 3. Organize– After the above two parts, the coherent knowledge points will become a pot of porridge, must be sorted out through the inductive logical relations, straighten out, restore to the original appearance, into a link to the tail of the knowledge chain
  • 4. Store– During sleep the brain injects this chain step by step into the hard drive

Basically the whole learning process is such a process, 1-2 can be understood as rough processing, 3 finishing, 4 is not under our control. We have to learn clearly, remember firmly, this process must be achieved, but most of the time we even do 1-2 difficult to do thoroughly, let alone 3, such a mess of knowledge points how do you let the brain to remember

Metaphor into the situation, such as when you rice merchants, other people give you a tuo red beans, millet, rice, purple rice mixed with unidentified material, you can only pick them out, but you don’t usually pick m, so pick m ability is very weak, in the short effective time, how many to you simply pick out, sometimes even a angry away, Who cares what this lump of shit is doing… Ha ha, we don’t laugh ah, temper explosion of the students, the subconscious is the same, and every day so you don’t bother, your subconscious is also bored, so this understanding, you learn how much can enter the brain

Why am I emphasizing tech blogging

Now it’s finally my destination to tell you about the importance of blogging. It’s very simple. When you look at the knowledge, unless you’ve seen a lot of similar knowledge, even if you think you understand it, there are still a lot of things that you missed or a lot of things that are illogical. Technology blog, you must first know it how many knowledge points, and then write it one by one point that can write understand basic that really understand, more than you think you see to understand, so you didn’t do even 1 or 2, when you write a blog technology will find to 1-2 completion, then the process of writing blog is 3. Help yourself to organize all the points of the knowledge clearly, so that the brain is very easy to remember the type of coherent data, naturally understand, remember clearly

Secondly, we will forget, forget if we look for their previous records on the line, the article is written by yourself, natural is to fit their own logic, so again learning, memory will be very easy

For example, I spent two weeks looking for information and writing examples for a certain knowledge point, but I didn’t keep records. Then half a year has passed, and you suddenly need to use it. At this time, you will find that there is not much that you can remember. How to do now

This is the benefit of technical blogging: completing the last mile of learning and creating a transcript that you can refer to and learn from later, and from my own experience, the advantages of blogging are unmatched
