This reminds me that hypertext also has a very important feature of writing permission management. For traditional information systems, it is very easy to modify information, which means a big information security risk. However, in hypertext system, modifying a page requires redeploying the url of that page, which greatly reduces the risk of information being tampered with by outsiders.

Considering this article is written to persuade CERN, fancy graphics may be equally important for the system. Fortunately, through development, hypertext system has already been able to show fancy graphics and audios.

This sounds like today's graph database.

It is exciting to witness this idea, which seemed impossible at the time, become a reality.

It is like use case analysis in today's software development.

In fact, I think even if CERN's experiments are static once-only development, they should not be stored in a book, because it will be substantially to search information in such a big book. The convenience to easily find information is also a great advantage of the hypertext system.

It is surprising that the World Wide Web is initialized for persuading CERN, the European Organization for Nuclear Research. I have searched some reference and it seems the world wide web was first designed for scientists to exchange their documents.

I think that problem still exists today. I once took over a project that a graduate student didn't finish when I was an undergraduate. Although the code was somewhat commented, there were no specific document to introduce the project. As a result, I spent a lot of extra time trying to figure out the technical details and system structure inside. Therefore, it is important to maintain a complete project documentation during the project.

This seems to be a simple version of today's navigation site.

And I think it may be more reasonable that once the new document is published, the former version should automatically become private. This can prevent other users from seeing wrong version.

I am wondering that whether the internet truly has private page (a website that nobody can view it )?

I guess how we implemented this today is by giving a specified URL to the linking item no matter what type it is.

An interesting thing is that I find many structure design is counter intuitive. For example, early database were implemented through hierarchical model, because such data storage structure is logistic and very easy for designers to understand. However, it was gradually replaced by relational database. Although relational database is more complex and hard to understand, it can substantially avoid redundant storage, and very easy to insert and maintain. So, sometimes designs that are very consistent with common sense are not the best, and we may need to step out our comfort zone and try to "find some troubles".

This reminds me of different diagrams to describe an interactive computer system, like Use case diagram, activity diagram, E-R diagram and so on. Comparing to describe programs in words, now I understand why these diagrams are very useful and easy to understand.

I think this opening shows two crucial factors of designing computer programs. "instead of staying bogged down..." indicates that the computer program should be innovative and efficient, which depends on the structure/ system design. "Think about when you..." indicates that the computer program should be humanized and easy-to-use, which is more related to UIUX design.

I don't think humans should lose hope because of the painful outcome. Instead, humans should think about the process, and try to avoid bad endings happen again.

This is very similar to our current concept of "intelligent furniture". We can remotely control them to complete some advanced tasks through intelligent terminal devices (like smart phone), but they usually look like ordinary furniture. It is amazing to see such philosophy early in 1940s!

I think the development is contrary to Bush's prediction. Bush thought we would make our language more suitable for machines our devices, while the truth is the language of machine was becoming easier and more suitable for humans to understand. For example, the development of programming languages, from assembly languages to C++, JAVA, and Python.

It's surprising to find that in 1940s, there has been voice-command software like Siri.

One interesting thing is that we always hate people who are picky about everything, but sometimes they can become pioneers.

Some great findings will not appear to be very useful and appealing at the first time. This reminds me the development of neural net work. In 90s, the most popular algorithm for machine learning is SVM (Support Vector Machine). Deep neural network has not been paid much attention, because it not only could not be explained by elegant mathematical model, but also required a lot of computing resources. However, after 10 years, with the development of GPU and optimization algorithms, deep neural network has become the dominating algorithm. So, we should not neglect the potential of a new discovery.

This reminds me that a breakthrough can never be one man's credit. Mondel is great, but we should also remember that a large number of scientists have worked extremely hard to refine and expand his findings.

This makes me think about how the information age has changed that relationship. Previously, knowledge was a rare wealth that only a few people can have. However, nowadays the information technology has made it possible for everyone to acquire knowledge easily, which changes it to a common wealth of mankind.
