  Why Good Programmers Are Lazy and Dumb

I realized that, paradoxically enough, good programmers need to be both lazy and dumb. Lazy, because only lazy programmers will want to write the kind of tools that might replace them in the end. Lazy, because only a lazy programmer will avoid writing monotonous, repetitive code – thus avoiding redundancy, the enemy of software maintenance and flexible refactoring. Mostly, the tools and processes that come out of this endeavor fired by laziness will speed up the production. This ma...

  Generate certificate in Java -- Self signed certificate

This is the first post in this series which I will show you how to generate SSL certificate in Java programmatically. Certificates are frequently used in SSL communication which requires the authentication of server to client. This is to make the client to trust that the server is actually the one it claims. Certificates are really important on the Internet. All HTTPS communications on the Internet need the server side to present their certificates signed by trusted CAs. The basic flow of a requ...

  Traditional recursion vs Tail recursion

Recursion is a frequently adopted pattern for solving some sort of algorithm problems which need to divide and conquer a big issue and solve the smaller but the same issue first. For example, calculating fibonacci  accumulating sum and calculating factorials. In these kinds of issues, recursion is more straightforward than their loop counterpart. Furthermore, recursion may need less code and looks more concise. For example, let's calculate sum of a set of numbers starting with 0 and st...

  Let 's write some front end codes

The low level development and machine learning are not the only technologies which are  full of wisdom and challenges, I wrote web site for a few years, it is difficult to say that this is my initial interest, although I touched on other technologies as well, I still feel building website is challenging. Front end developme...

  Disgusting programming language list

To avoid arguments among different programming languages, this ranking only covers the opinions from programmers with multi-language experience. Also it doesn't mean the language is not good if the language is on the list, it just means those developers don't like some features of the language. Below ranking is summarized from Quora、Stack Overflow and Hacker News. 10. Python Reason : It uses code indent to define block level scope, why not use curly braces? It also uses massive colons and ...

  Why do business analysts and project managers get higher salaries than programmers?

People get paid less than their employers' "reservation price" (the most they would ever pay), and more than their "marginal product" (the least they would ever work for). Your actual pay on that spectrum is based on your bargaining power, relative to your employer.Say your services to your company are worth $1000 a day. Under the gun, he would pay you that if he had no other choice. Say you would work for $100 a day if you had no other options. That's your range.Say you're new and independent a...

  Access control in Java -- doPrivileged

Previously we have introduced how Java performs permission check to protect resource access. What if sometimes we need to give some class the temporary access to some resource which it initially doesn't have? AccessController provides six doPrivileged methods to fulfill this requirement. These six methods have below signatures : static T doPrivileged(PrivilegedAction action)static T doPrivileged(PrivilegedAction action, AccessControlContext context)static T doPrivileged(PrivilegedExceptionA...
