SQLite3 multithreaded example
A little test of sqlite3 thread safety across multiple processes.
Ensure sqlite is built with:
#define SQLITE_THREADSAFE 1
poll.c will create database and table if necessary and start polling for inserts.
writer.c will insert the current time into the db once every second.

RoR log parser
A dirty little script to grab performance stats from Rails production.log file.
To speed up I recommend grep'ing out relevant lines:
egrep ('Started'|'Completed') production.log > output.txt
Will give you a CSV file which you can quickly plot in Excel.

iOS 6 SMS database dumping
Looking into how to retrieve SMS archives from iOS 6.
Useful resources:
http://lasc.livejournal.com/284909.html
To explain the datetime mangling:
"The timestamps are not traditional timestamps of the number of seconds from 1/1/1970, but are instead based on the number of seconds from 1/1/2001 (so, there is a 31 year offset). So, we have to add the number of seconds in 31 years (978264705) to the timestamp to change it to a traditional timestamp giving the number of seconds from 1/1/1970."
Query below will pull a history of all message to and from the PHONE NUMBER specified.

factory_boy Sequence customisation

factory_boy Sequence

factory_boy allows you to define attributes as sequences, e.g.:

class MyFactory(factory.Factory):
    id = factory.Sequence(lambda n: "ID%s" % n)

By default, the sequence type is a str.

jsok / locale_hack.py
Created February 3, 2013 06:03
A little hack to switch locales and override some locale conventions temporarily.
# Store the current locale
default_loc = locale.getlocale()
# Swap to some foreign locale, e.g. German
locale.setlocale(locale.LC_ALL, 'de_DE')
# Define a new localeconv() with some overrides
# see http://docs.python.org/2/library/locale.html#locale.localeconv
def _temp_localeconv(lc=locale.localeconv()):
lc.update({'decimal_point': ',', 'thousands_sep': '.'})
