cp command implementation and benchmark in python, go, lua

   |  708 words  |  Kracekumar

I was wondering how much will be the speed difference between cp command, rsync and implementation in python, go, lua and so wrote this code. Background python has two versions one with gevent and without gevent. Both the version uses shutil for copying files and directory tree. go uses https://github.com/opesun/copyrecur for copying recursively. lua uses lfs - LuaFileSystem module. lfs has support for creating directory but not for files, in order to copy the files low level file opening and writing to file technique is used.

Python parallel assignment

   |  138 words  |  Kracekumar

Python supports parallel assignment like >>> lang, version = "python", 2.7 >>> print lang, version python 2.7 values are assigned to each variable without any issues. >>> x, y, z = 1, 2, x + y Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'x' is not defined First python tries to evaluate x + y expression. Since x, y is defined in same line, python is unable to access the variable x and y, so NameError is raised. [Read More]

Can PyPy be used for web application deployment ?

   |  278 words  |  Kracekumar

What is PyPy ? PyPy is an implementation of Python in Python which uses JIT(Just In Time) translation. Why to Use PyPy? According to benchmarks “It depends greatly on the type of task being performed. The geometric average of all benchmarks is 0.18 or 5.6 times faster than CPython”. Experience? I have used PyPy for sandboxing for my project pylive, tested flask with pypy, ported brubeck to work on pypy, tested lastuser in PyPy 2. [Read More]

Microframeworks produces micro level progress in project

   |  153 words  |  Kracekumar

I created my first web app in PHP 5.2 with * no frameworks *, then learned drupal, tried codeigniter, joomla. Then I learned Rails for HappySchool project and learned Django since I am python lover. Tried Pylons and settled with Flask and experimenting brubeck. Flask is microframework built around werkzeug datastructures. Advantages Vs Disadvantages Learn in depth working of HTTP vs Time consuming Opportunity to create library vs Time consuming Less batteries available vs More development time It is highly loosely coupled which is good to replace the parts with best tools if available.

Python *in* operator is membership test operator.*Examples:*List—- In [1]: python_webframeworks = ['flask', 'django', 'pylons', 'pyramid', 'brubeck'] In [2]: 'flask' in python_webframeworks Out[2]: True In [3]: 'web.py' in python_webframeworks Out[3]: False in operator iterates over the list of elements and returns True or False. What about nested list? In [4]: webframeworks = [['flask', 'django', 'pyramid'],['rails', 'sintara'],['zend', 'symfony']] In [5]: 'flask' in webframeworks Out[5]: False in isnt handy for nested list, unless it is overriden.
