oops,java gained its popularity of what?!
【 在 magicfat (魔法胖子) 的大作中提到: 】

: : hehe. I have to say. This is not that right.
: : 1. It's hard to persuade clients using this words.
: Show them the bottom line, and they will be "persuaded". LOL
: : 2. Java and C# is not that "efficient" as you said.
: : A real professional C++ programmer can achive almost
: : the same productivity as Java programmers. But this kind of
: I would be glad to believe that if you have some statistical data supporting
: it. Besides, I was comparing C to Java/C#.
: : c++ programmer needs long time to train.
: And hence more expensive to hire, which adds to the right side of your
: "persuasion". 8-)
: : The key points here are:
: : 1. java and C# is popular because they are easy to use and powerful
: : enough to do general stuffs.
: : 2. system level knowledge is necessary. For c++ programmer, you have
: : to know the details of memory mangement and .... For java and C#,
: : you have to know how VM runs and memory mangement. The only differnece
: : is your program may not that easy to crash in VM.
: No... you don't have to know how the VM works or how memory management works
: write good quality Java programs. In fact, sometimes I think overly
: on the details can hurt the overall quality of your program, because it
: distracts you from working on the real significant aspects - your algorithm,
: your design, and your metrics quality.
: : 3. Performance sometimes is requirement. Finishing a functioning system
: : doesn't mean you developed a succesful product. In business world,
: : those words like "hardware will solve the problem" doesn't work. :)
: It doesn't work? How do you think Java gained its popularity, and C# is
: gaining its?
: LOL, come to think of it, now I realize that the "hardware takes care of it"
: approach actually works a lot better in the business world than in the
: academic one.
give us grace to accept with serenity the things that cannot be changed,
courage to change the things which should be changed and the wisdom to disti
nguish the one from the other.
