Python script to split bulk vcard file to individual vcard files.

I have brought a new low end mobile GT-E1232B from Samsung. I wanted to export all the contacts from my LG android phone. Samsung mobile accepts vcard but, each contact should be in a separate vcard file. Sending the one by one from Android is a boring task and also the build import of vcard dint work in Samsung mobile.  So I decided to write a small python script to split the bulk vcard into small separate vcards for each contact in my pc and copy them to SD card an import them in Samsung mobile. I am sharing this script so it might be useful for some one.

#!/usr/bin/env python
outputBase = 'output' # output.1.txt, output.2.txt, etc.
inputfile = 'contact_2012_6_6_8_45.vcf'
input = open(inputfile, 'r').read().split('\n')
count = 1
for line in input:
 output = open(outputBase + str(count) + '.vcf', 'aw')
 output.write(line)
 output.write('\n')
 output.close()
 if line.startswith("END:VCARD"):
 print str(count) + " VCARD Splitted"
 count += 1

Chandler is an open source Note-to-Self Organizer.

Chandler is an open source Note-to-Self Organizer. It features calendaring, task and note management and consists of a desktop application, web application and a free sharing and back-up service called Chandler Hub.

URL: http://chandlerproject.org

According the Chandler project website.

Our goal is to serve the way people actually work, independently and together, particularly in small groups, a market segment we believe is undeserved. Our belief is that personal and collaborative information work is by nature iterative and that the existing binary Done/Not-Done, Read/Unread, Flagged/Unflagged paradigm in productivity software poorly accommodates the reality of how people work.

We are also committed to breaking down technological barriers that prevent effective collaboration. Chandler Desktop and Chandler Server are cross-platform and standards-based because we realize that collaboration can’t and shouldn’t be trapped within a single system. Chandler Server provides web access to shared information that makes it easy for collaborators to hook into Chandler work flows without having to download the Desktop application.

How to turn off specific optimization flags in gcc

How to turn off specific optimization flags in gcc

For example I want to compile with optimization -Os, but -Os optimization turns on -ftree-dce. How do I turn it off -ftree-dce alone?

There is usually an equivalent ‘no’ flag. For example, -ftree-dce can be turned off by -fnotree-dce. Check the gcc docs for more flags.
