Full changes log

Table of contents: Tools, Research, Publications, The City of Toruń, Junk Room, Links, Polish Corner.
  Tools:

  • Sphinx interactive documentation: a support for per-paragraph comments and user/developer interface for submitting/committing fixes.

    My application is available here. I am blogging about this project here. And the repository is available on Bitbucket.


  • Dots Connector - Social Networks Analyzer.
    Dots Connector: Groups of friends

    Dots Connector is a set of tools designed to analyze social networks created by people while adding friends to their buddies lists in social network services (such as Facebook, Bebo or Nasza-Klasa.pl).

    It treats networks of connections between people as its main source of information, it connects, splits, compares the data to show how much we say about ourselves just by adding friends to our buddies lists.

    At the moment it consists of two tools:

    • Chain seeker - searches for a path between two given users,
    • Groups seeker - analyzes buddies list of a given person and produces a report about groups that person lives in.

    The main purpose of developing Dots Connector is sociological research, but it can also be educational and entertaining for general public.

    You can download the code here, but keep in mind that it is a development version and works only for Nasza-klasa.pl. Some theoretical stuff is available here.

    Example output for groups-seeker is available here.

  • procpy - python wrapper for procps library + a module containing higher level classes (with some extensions compared to procps).

    Procpy module provides three classes:

    • Proc - an instance of Proc class keeps the data gathered from process table (/proc directory) at initialization and does not update it automatically. Thus, you actually work with a copy of process table that might be out of date at the momment of initializing an instance.

    • ProcRT - an instance of ProcRT class updates its data before accessing given attribute or executing a method. This class is more CPU-time and memory consuming. The gain is that you always have accurate informations about processes running in your system.

    • Pid - an instance of Pid class works with the data for one process, but it also contains info about its parent. Example: 

      #!/usr/bin/env python

import os
import procpy

a = procpy.Pid(os.getpid())
print "Current process: %s (%d)" % (a.cmd, a.pid)
print "Command line args:", a.cmdline
print "Executable:", a.exe
print "HOME:", a.environ['HOME']
print "Opened files:", a.fds
print "Parent: %s (%d)" % (a.parent.cmd, a.parent.pid)
print "Parent's executable:", a.parent.exe
print "Parent's opened files:", a.parent.fds

    Within the package you will also find a getutent() wrapper and its modification called wgetutent() that extends getutent() structure with some /usr/bin/w-specific fields such as IDLE, PCPU and JCPU.

    Procpy is still in development stage. Source code is available here. The code is also available through the google-code pages. You can also find additional docs on the wiki pages.

  • Sphinx RST to PDF builder. Corresponding branch of the Sphinx repository is available here. This is a work-in-progress. The builder works, but is not fully functional yet.


  • Smaller projects, code snippets, etc.:
  Research, semi-research, quasi-research:
