But there is another,newer language, called python, whose users tend to look down on perl,and if you look at these languages in order, java, perl, python,you notice an interesting pattern. Many people have responded to this talk,so i have set up an additional page to deal with the issues they haveraised mailing list. So, whos right? James gosling, or the pointy-haired boss?not surprisingly, gosling is right. And you shouldnt have trouble hiringhackers on that scale for any language anyone has ever heardof. Withinthe hacker subculture, there is another language called perlthat is considered a lot cooler than java.
Im not saying that you wont get a lot of pressure to usewhat are perceived as standard technologies Buy now Write A Compare And Contrast Essay Yahoo Answers
We know that java must be pretty good, because it is thecool, new programming language. Many people have responded to this talk,so i have set up an additional page to deal with the issues they haveraised mailing list. In a project of thatsize, powerful languages probably start to outweighthe convenience of pre-existing libraries. But all languages are not equivalent, and i think i can provethis to you without even getting into the differences between them. The nine ideas are, in order of theiradoption by the mainstream, conditionals.
As one data point on the curve, at any rate,if you were to compete with ita andchose to write your software in c, they would be able to developsoftware twenty times faster than you Write A Compare And Contrast Essay Yahoo Answers Buy now
In server-based applications you canget away with using the most advanced technologies,and i think this is the maincause of what jonathan erickson calls the. That may soundlike a bizarre idea, but its an everyday thing in lisp. So how would you do it? In the limit case,by writing a lispinterpreter in the less powerful language. What problems? When is java better and when is c? Are there situations where other languages arebetter than either of them? Once you start considering this question, you have opened areal can of worms. Lisp macro can be anything from an abbreviationto a compiler for a new language.

That sounds like a joke, but it happens so often tovarying degrees in large programming projects thatthere is a name for the phenomenon, greenspuns tenthrule any sufficiently complicated c or fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of common lisp. So-called mainstream languages started outfast, and over the next forty years gradually got more powerful,until now the most advancedof them are fairly close to lisp. Lisp looks strange not so much becauseit has a strange syntax as because it has no syntaxyou express programs directly in the parse trees thatget built behind the scenes when other languages areparsed, and these trees are madeof lists, which are lisp data structures Buy Online Write A Compare And Contrast Essay Yahoo Answers
Mccarthy said later, another way to show that lisp was neater than turing machineswas to write a universal lisp functionand show that it is briefer and more comprehensible than thedescription of a universal turing machine. The disadvantage of believing that all programming languagesare equivalent is that its not true. What problems? When is java better and when is c? Are there situations where other languages arebetter than either of them? Once you start considering this question, you have opened areal can of worms. Expressing the language in its own data structures turnsout to be a very powerful feature. If so thenwe can put some faith in it itas software includes a lotof c and c as well as lisp, so they are speaking fromexperience Buy Write A Compare And Contrast Essay Yahoo Answers Online at a discount
So when i say it would take itas imaginarycompetitor five years to duplicate something ita couldwrite in lisp in three months, i mean five yearsif nothing goes wrong. The combined code can be much shorter than if youhad written your whole program in the base language-- indeed,this is how most compression algorithms work. The nine ideas are, in order of theiradoption by the mainstream, conditionals. Suddenly, in a matter of weeks i think, mccarthy found his theoreticalexercise transformed into an actual programming language-- and amore powerful one than he had intended. But when you importthis criterion into decisions about technology, you startto get the wrong answers.
This makes the programmer do the kind of codeanalysis that would be done by the compiler in a languagewith full support for lexical scope, and it wont workif more than one function refers to the same variable,but it is enough in simple cases like this For Sale Write A Compare And Contrast Essay Yahoo Answers
Andso while you needed expressions for math to work, there wasno point in making anything else return a value, becausethere could not be anything waiting for it. What we mean by a programming language issomething we use to tell a computer what to do. That is, he compiled the in my paper into ibm 704 machinecode, fixing bugs, and then advertised this as a lisp interpreter,which it certainly was. The factthat all these languages are turing-equivalent meansthat, strictly speaking, you can write any program inany of them. It was natural to have thisdistinction in fortran i becauseyou could not nest statements.
