Python Magic – Find the Most Recently Modified File

I had a very interesting assignment today. Find the most recently modified file in the CVS repository!


 

Write a program in Java? This is my first choice if any problem comes to my mind! Well, iterating through tens of thousands of file to find the latest modified file. This can be a killer program if do it in java! Over the years I kind of looked down at the Scripting languages. I was amazed- how few lines of Python code can do wonders!


 

import os, time, glob


 

folder = "<FOLDER NAME IN UPPER CASE>"

oldModifiedFileName = ""

oldModifiedFileDate = ""

lastmod_date = ""


 

for infile in glob.glob( os.path.join(folder, '*') ):

    for (path, dirs, files) in os.walk(folder):

        for file in files:

            filename = os.path.join(path, file)

            stats = os.stat(filename)

            lastmod_date = time.localtime(stats[8])

            file_date = time.strftime("%Y%m%d %H:%M:%S", lastmod_date)


 

            if file_date > oldModifiedFileDate:

                oldModifiedFileDate = file_date

                oldModifiedFileName = filename


 

print "Last Modified FileName " + oldModifiedFileName + " Modified Date : " + time.strftime("%Y/%m/%d %H:%M:%S", lastmod_date)

SAAS Simple Maturity Model

There are two architectural models – commonly referred as SAAS Maturity models- that describe the transition of a service to what is called Multi-tenant efficient, highly scalable application. The SAAS Maturity model described by Microsoft has four distinct stages and is illustrated below. Another similar well-known model for SaaS-maturity is known as Forrester-model but adds another stage known as "Dynamic Business Apps-as-a-service". The three key Attributes of a SAAS Architecture: Configurability: Metadata used to configure the way the application behaves for customers Multi-tenant Efficiency : Maximizing the sharing of resources across tenants Scalability: Maximizing concurrency, resource efficiency SAAS Simple Maturity Model (Microsoft, 2006) SaaS Maturity Model (Forres...
