On Linux:

rm -rf `find . -name .svn`

On Windows

Create a .bat file (some name like: delete_svn.bat) at the root of the directory from where u want to delete all .svn subfolders

for /f “tokens=* delims=” %%i in (’dir /s /b /a:d *svn’) do (
rd /s /q “%%i”
)

- Create a Cronjob class to handle the cronjob: this class will do the all the tasks that need to be done regularly
- Use javascript at client side to refresh the Cronjob page at a regular time interval.

I think the idea is simple, it does solve the problem but require you to have the page opened all the time. Some of you may have better idea?

Okay, now is how i managed everything to work with some helps from James Tauber on #pinax irc

+ Before downloading Pinax 0.5, you need to setup Apache2, Django & mod_wsgi on Slackware 12.1, configure and load mod_wsgi in apache. Googling will be your friend

+ Download Pinax from http://pinaxproject.com/download

+ Unzipped to /srv/pinax

+ Firstly initialize the database (sqlite3):

#/srv/pinax/projects/complete_project/manage.py syncdb

This will create dev.db in complete_project, it will create an user during installation for you to login

Okay, now it’s time to adjust something

+ To run in mod_wsgi, the database file should be in absolute path, so edit /srv/pinax/projects/complete_project/settings.py:

DATABASE_NAME = ‘/srv/pinax/projects/complete_project/dev.db’

+ Add a symlinks to your django admin media folder (mine is at: /usr/lib/python2.5/site-packages/django/contrib/admin/media/)

#ln -s /usr/lib/python2.5/site-packages/django/contrib/admin/media /srv/pinax/projects/complete_project/admin_media

+ Made everything owned by apache user/group

#chown -R apache:apache /srv/pinax

+ The wsgi for deployment stays in /srv/pinax/projects/complete_project/deploy/complete_project.wsgi, we need to specify this in the apache virtual host, here is mine /etc/httpd/extra/httpd-vhosts:

<VirtualHost *:80>
ServerAdmin admin@pinax.dev.com
ServerName pinax.dev.com
DocumentRoot “/srv/pinax”
WSGIScriptAlias / /srv/pinax/projects/complete_project/deploy/complete_project.wsgi
Alias /site_media /srv/pinax/projects/complete_project/site_media
Alias /media/ /srv/pinax/projects/complete_project/admin_media/
WSGIProcessGroup pinax
WSGIDaemonProcess pinax user=apache group=apache threads=25

<Directory “/srv/pinax”>
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
ErrorLog “/var/log/httpd/pinax.dev.com-error-log”
</VirtualHost>

(Note: You need to put an entry in /etc/hosts for pinax.dev.com point to 127.0.0.1)

+ Restart the apache server #/etc/rc.d/rc.httpd restart

+ Browse http://pinax.dev.com to see if it works. If you encounter the PYTHON_EGG_CACHE problem then create folder .python-eggs inside /var/www and made it owned by apache user/group

Hope that will work for u too. Still not working, head on #pinax irc, you might get the answer

Kodos is a Python GUI utility for creating, testing and debugging regular
expressions for the Python programming language. Kodos should aid any
developer to efficiently and effortlessly develop regular expressions in
Python. Since Python’s implementation of regular expressions is based on
the PCRE standard, Kodos should
benefit developers in other programming languages that also adhere to the
PCRE standard (Perl, PHP, etc…).

You can download and try it here

Depends on your current installed packages, you may be required to install some other packages, for details of the dependencies, please refer to it’s wiki

Mapnik requires the Boost libraries, International Components for Unicode, Freetype, Proj4, and a variety of image libraries.

Installing Boost is often new to mapnik users, but the majority of remaining dependencies are more familiar.

If you have previously built or installed other open source graphics or mapping applications it is likely that most of the remaining dependencies are already installed.

Currently detailed notes on mapnik dependencies are included in each platform specific installation instructions.

See MapnikInstallation for more information.

Before installation, check your boost lib compatibility here
The boost lib I got from LinuxPackages.Net for Slackware 12.1 is at version 1.36, which is not compatible with mapnik 0.5.1 (I got error while compiling), so I took boost version 1.35 from here

- Install boost lib package
- Install scons package (from slacky.eu), requiredbuilder (from stabellini.net )
- Download SlackBuild of Mapnik for Slackware 12.1 from slacky.eu , put everything in the same folder (e.x /home/download/mapnik-slackbuild/)
- running #./mapnik.SlackBuild
- If everything is ok, you will get mapnik package at the same folder with the slackbuild scripts, install it like other Slackware packages.

Test your Mapnik:

Once the installation is completed, you can test your installation by running a Python Hello World with Mapnik (You can see detailed instruction from here). Here is my summarization

1. Download the data, put it in /home/work/mapnik/data/ & unzip it
2. Copy the python code below, put in it a file name world.py at /home/work/mapnik/

#!/usr/bin/env python

from mapnik import *
m = Map(600,300,“+proj=latlong +datum=WGS84″)
m.background = Color(’steelblue’)
s = Style()
r=Rule()
r.symbols.append(PolygonSymbolizer(Color(‘#f2eff9′)))
r.symbols.append(LineSymbolizer(Color(‘rgb(50%,50%,50%)’),0.1))
s.rules.append(r)
m.append_style(‘My Style’,s)
lyr = Layer(‘world’)
lyr.datasource = Shapefile(file=‘/home/work/mapnik/data/world_borders’)
lyr.styles.append(‘My Style’)
m.layers.append(lyr)
m.zoom_to_box(lyr.envelope())
render_to_file(m,‘world.png’, ‘png’)

3. Go to /home/work/mapnik/ and run the script #python world.py, if you get the world.png file in the same folder then everything is fine, mean the installation was successful

Real-word Examples:

You will find a lot of projects started to use CouchDB here

Hope that you find them useful for getting start with CouchDB, I will try to keep this up-to-date, so help me if you can

1. mod_python is compiled for Apache2, if you don’t know how then proceed here
2. I used official release from Django, check out here if you need help with the installation
3. Install Erlang, CouchDB as described in my previous post
4. Install CouchDB Python binding is easy with easy_install couchdb
5. I set up a virtualhost to run my couchdb-django testing (/etc/httpd/extra/httpd-vhosts.conf)


ServerAdmin abc@abc.com
DocumentRoot “/srv/djangocouchdb”
ServerName django.dev.com

Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all


PythonPath “[r'/srv/'] + sys.path”
SetHandler python-program
SetEnv DJANGO_SETTINGS_MODULE djangocouchdb.settings
PythonHandler django.core.handlers.modpython
PythonOption django.root /couchdb
PythonDebug On



(well, i made my /etc/hosts file to have entry for django.dev.com for sure )

6. Then I followed instruction from HERE to create my django project and couchdb app inside that project. And everything worked, just with a little problem (access denied) with PYTHON_EGG_CACHE which in my system refered to /root/.python-eggs. I reset PYTHON_EGG_CACHE to /tmp and restarted my server, then everything worked fine.

Now it’s time to explore more

obj/i686-pc-linux-gnu/opt/smp/hipe_x86_signal.o: In function

`sigaction’: hipe_x86_signal.c:(.text+0xa9): undefined reference to

`INIT’ hipe_x86_signal.c:(.text+0xff): undefined reference to

`__next_sigaction’ obj/i686-pc-linux-gnu/opt/smp/hipe_x86_signal.o: In

`__next_sigaction’ collect2: ld returned 1 exit status

After looking at erts/emulator/hipe/hipe_x86_signal.c , it turned out to be the check for glibc version which should be >=3 && <=6, and my current glibc is 2.7. So just for it working, I modified the code to check for my glibc version and yaaa… it worked!!!

CouchDB require ICU to work, so i hooked up linuxpackages and get ICU package, now is the time to build CouchDB package, well I used src2pkg to build my Slackware package.

Running CouchDB with couchdb user

As root, do:

adduser couchdb
chown -R couchdb /usr/var/lib/couchdb /usr/var/log/couchdb
ln -s /usr/etc/rc.d/couchdb /etc/rc.d/rc.couchdb
/etc/rc.d/rc.couchdb start

Everything went smoothly … time to relaxxxx !!!
