Efficient Internet access and systematic learning

Preface

I have been in contact with the Internet for more than ten years , The whole world seems to have undergone earth shaking changes . People in the past , Like posting , Forum . And now , do not know why , I picked up my cell phone , It's as if I lost something after I left my hand . Turn on Tiktok or B Almost , Sliding one by one , I can see that I don't sleep in the middle of the night .

Holding the cell phone in your hand , We seem to have become ghosts , Swing between the real world and the virtual world .——《 Glass cage 》 Nicholas · Carl

English Search

Why do we need English Search ？

I don't know if you have the same experience as me . For example, in the process of program development , Have a problem , I may go to the search engine to search . But what we have to understand is , There are too many content farms on the Chinese Internet . Almost all are collection stations , Not only does it not help you , It will also affect your mood .

Maybe you have questions , High quality Chinese content is also available ？ I have no objection to that , But the collection station seo, Often do better than an independent blog , I'm sure you know that . Even some search engines , I have been doing things that degrade Chinese search , I don't want to say that everyone knows ？

Of course , Don't talk about the scene , It's just playing hooligans ！

But I believe , Every reader should know when to search in Chinese , When to search in English , And how to choose a search engine

So if you want to ask , I search in English , There is also a lot of content about the farm , Sometimes I can't find anything . Don't worry. , Let's move on ！

Basic English search skills

The simplest , Can think of immediately , Is absolutely ： key word + introducer .

For example, we can search ：Java Tutorial.

Give us some common guide words ：

• summary （Overview,Introduction,Getting Started）
• guide （Tutorial,Guide,Howto）
• Function reference （Reference,Index）

Possible logical relationships ：

And （ Generally blank ）、 or （OR）、 Not （-）

for instance ：Java -csdn

Science and the Internet

Why do we need scientific Internet access ？

The sensitive factors will not be discussed here , Simply from the academic and Internet comfort to consider .

Just mentioned above , Domestic search engines , The experience is really a little bad , Especially the bidding ranking and collection station , As a result, the first page is basically not what you want to find . And things like Google Search engines like that , It can be avoided to some extent . Then there are some learning materials 、 Film and television materials , We also need the help of scientific Internet to have a good search and use experience .

This is when developing programs , Searching for information is a deep experience ！ There is no firm tool , Only those who are willing to learn ！

Get and filter information

understand “ Media form ”

Media form is the living state of media （ Including the external form of the media and the communication symbol as the internal structure ）、 Survival basis 、 Media communication methods （ Including the forms and ways in which the audience receives media information ） As well as the media functions and characteristics displayed thereby .

For example, when we want to learn Java when , You can go to B Stand and watch the video 、 You can also read 、 Look at the official documents , You can also read various blogs , These belong to “ medium ”.

Of course , Different forms of media , Bring you “ Information ”, It's also different . for instance , Study Java And watch the video , It can really get you started quickly , But this passive form of media , It will be inevitable “ Inhibition ” Your thinking . Video makes your brain stay in “ Heart comfort zone ”, How much you think about things , Is far less than reading .

Books as a medium , Have initiative 、 Systematic and profound advantages . Areas of replication like programming , Books are “ systematicness ” In terms of , The advantage is no less than any other medium .

Access to information

Personal information source plays an important role in social information exchange system . Man is a social species , People in a society have a strong demand for information , And the information source will influence your action decision . An inefficient and low-quality information channel may make you make many wrong decisions , That will make you form the wrong cognition .

We can talk later , How do I build myself “ Information sources ” Of ~

DIKW Model

DIKW Models are a good way to help us understand data （Data）、 Information （Information）、 knowledge （Knowledge） And wisdom （Wisdom） A model of the relationship between , This model also shows us how data is transformed into information step by step 、 knowledge 、 And even the way of wisdom .—— source ： Encyclopedia of think tanks

To better understand this model , We need to know , What does each layer of the model do , And the difference between adjacent levels . Now I'll take everyone's daily life , Let's give an example of the most inconspicuous thing , you 're right , Namely ——“ Spend money ”.

data (Data) And information (Information) The difference between

You spend money every day , Isn't it ？ Every dollar you spend , Can be recorded , In a way , Every record , It's just a piece of data , It doesn't make sense . Because the data at this time , Or belong to “ source ” The form of . however , We can put every day , Every month , Annual data summary , Then we deal with it accordingly , Is it possible to get some information ？

For example, the total income and total expenditure of a year 、 Which month is the most expensive , Where did all the money go ？ These are all “ Information ”. We analyze the original data , Got information . This information is divided into explicit and implicit , such as ： who ？ what （ Content ）？ Where? ？ What time? ？ Why do things turn out like this? ？

Single data , It doesn't make sense , But when we turn it into information , Its meaning naturally appears ！

Information (Information) And knowledge (Knowledge) The difference between

The lifecycle of information is too short , So that you don't take the initiative to digest it , It will also lose its meaning . for instance , You can reflect on the past year , What are the things , You bought it but you don't have to buy it , And expensive things . The consumption records of the past year （ Information ） We summarized 、 Compare 、 replay , Precipitate the valuable part of the information , And combine it with the existing knowledge system , Then this part of information will be transformed into knowledge .

Think about reading , When the teacher explained the topic on the platform , It suddenly occurred to you that you had done another similar topic , Then a comparison is made , This is also the process of transforming information into knowledge .

knowledge (Knowledge) And wisdom (Wisdom) The difference between

Knowledge and wisdom , My personal understanding is ： Knowledge focuses on the past , Wisdom cares about the future .

Quote a professional explanation ： Human beings are based on existing knowledge , In view of the problems arising in the process of movement in the material world, analyze them according to the obtained information 、 contrast 、 Deduce the ability to find solutions . The result of this ability is to dig out the valuable part of information and make it a part of knowledge architecture .

Combine search engine to mine network resources

We talked about it , Why should we use English search and scientific Internet .

But at the search engine level , Try to choose Google Search engines like that . And I suggest you use google.com/ncr , So you can use the international version （ Disable country redirection ）, Small partners who often visit the open source community should see many people recommend it .

Web snapshot

Basically, many people have met 404 and Redirect , This will give us a bad Internet experience . We can prefix the address with cache: , such as baidu.com become cache:baidu.com. Or you can use the Internet archives （Internet Archive） To search , View a text only snapshot , It can also filter out JavaScript Script , It will also be safer ！

Filter search

Can be combined with search engine syntax , Do a filter search . For example, only view the relevant content of a website , Or search for specific files .

Search engines can't find what to do ？

Generally, there are several situations , You may not find the information you want ：

• Corresponding content provider , Intend to “ Enclosure ”, Search engine crawling is prohibited .
• Not recorded yet .
• You opened it the wrong way .
• Too many content farms , You can't find normal content , And lose patience ！

I also give several corresponding solutions here ：

• See how others search （ Yes that's right , You can search for relevant content , Learn how others search the content you want ）.
• Take the time to learn search engine syntax .
• Professional business , Give professional tools to do . For example, you want to find a Book , Sometimes search engines are not the best solution , Might as well try. z-library.
