In this society, no matter who lives in this world, there will inevitably be some regrets. This article introduces me as a code farmer to the code farmer, the biggest pity, I hope MFA can learn from this. More than 20 years ago, I was at a crossroads in my life. With the end of Deltagraph created by publishing houses (they hope to enter the emerging Internet space) over the past five years, my second company has gradually declined. At that time, I had

With the increasing popularity of the concept of cloud computing, IT companies began to apply cloud computing to storage, transactions, finance, security, and many other fields. However, as there are more and more named "Clouds", the security issues of the "Cloud" itself have become the biggest obstacle to its development. What do you think are the challenges and problems of the cloud computing model ?" In the survey, Security ranked first with 74.6%

from Cantor Set up in the park. At this point, Cantor's academic injustice was thoroughly vindicated. Historically, the points on the plane were significantly more than the dots on the line. This is the intuitive "truth" of man. But Cantor has proved that this is the wrong idea. As a result, Cantor violated the academic "rules", was beaten to "scientific liar", "traitor", wronged for many years. For this reason, since 1884 years, Cantor has suffered from severe, recurrent episodes of mental dep

repeatedly day after day? In fact, when you continuously program in a system (adding new things), the system becomes complicated and the biggest challenge you face is how to sort out your own products. That is to say: university education only teaches us how to "Add new things", but does not educate us how to "organize these things". The latter is the new impetus for the ever-changing revolution in the software field. The following is a detaile
