My feelings about Learning Technology

I accidentally saw this article today. Article:
Examples of failed technical attempts over the past few years
I feel a little bit about learning.

I just graduated from ASP, a small network company. At that time, I saw a variety of pessimistic arguments, saying that ASP would not work, and there was no future for doing this ....... so I have been trying to read variousProgramming Language, Trying to become a 10 thousand person. I learned the C language by myself. I felt that it was difficult to test and I was unable to wait for the cainiao to do so. Later I thought that VB may be simple, so after a while, I had no project practice and gave up. nhib.pdf, I learned to give up because I didn't have the technical decision, and I had to give up on it. I tried to do a few demos myself, but I didn't know how to give up. WWF wanted to learn it. I didn't understand it after reading a month's book and gave up; SQLite, play with it as a toy; PHP + MySQL, once a project, give up; now Linux, Python interest, occasionally drum up.
Now I understand that I have learned these things and I will make several more choices for project development. Which method can be used to achieve the demand more easily and quickly. when creating a system, I will make a choice. For example, if deleting a file on the ASPX page fails, I will record the file path to a specific file, then, you can use a vbs service script to delete the recorded files every clock period. language learning is an option for solving possible problems. to put it bluntly, it is just a tool.
I recently interviewed a company and asked a question: How much do you know about the latest. NET technology? To be honest, I feel a little uneasy ,. net many, do not know what is new. later, they talked about how they used Silverlight to develop internal systems. To be honest, I have never touched on it. It seems like a XAML description element, similar to flash, which is a plug-in. I don't know if it is new, but I am new; WCF, not used in actual projects, and I am new; the interview concluded that my vision was not wide enough. haha... or that sentence: language is a tool, and it is key to quickly solve the application problems it faces. this requires an understanding of the features of each language.
