Changing the default google calendar event length Tuesday, Jan 20 2009 

Google App Engine and How To and MS Windows zoqui 2:35 pm

The default event time for all google calendar is one hour (1 hour), and there is no way to have it configurable. Most of therapist needs 30 minutes event, and for those who uses the google agenda, it is quite bit effort to get it right. There are already several posts asking how to change this time, but till now no response from google team.  So I have creted a very small program to make it easy to have 30 minutes event.

  • Download the executable
  • Execute it. You will notice a new Z icon at your system tray
  • You will notice a new tray icon (Z)
  • Now open the firefox and navigate to your google calendar page
  • Press ALT-Z and type the name of the patient and the the starting time.
    e.g: Albert 13:30

It is a good idea to make a startup shortcut to save even more time ; -)

The script was compiled by AutoHotKey, and its source code can be download here

Portable Google Chrome – II Friday, Sep 5 2008 

Google App Engine zoqui 7:38 am

Plasmid sent me a nice tip that I put here in his own words:
“…if you move ‘chrome.exe’ and ‘Dictionaries’ into the 0.2.149.27 directory, you should
be able to copy the whole lot onto a USB stick and it works without needing the registry keys!”

So no run.bat file or registry entries are needed.

He has created a really portable chrome browser

Thank you Plasmid – Great Job!!!

Portable Google Chrome Version (9.3Mb) Wednesday, Sep 3 2008 

Google App Engine and How To and MS Windows , , , , zoqui 4:06 pm

Google Chrome is really nice, but it does a quite dirty installation… It write several registry entries, does not give you the option to select where you want to install, forces the bookmark importation from the current default browser, etc.

Yes, it is possible to run this brilliant browser in any folder you desire.  No configuration is needed, but also a single language is enabled (American Engligh).

How to install this portable version:

  • Download and uncompress the GoogleChromePortable.zip in any folder you want.
  • Execute the RUN.BAT file (on the windows explorer, open the GoogleChromePortable folder and double-click on it)

That’s all.
Enjoy it

Hands-On #7 Working with gcalendar events on GAD Thursday, May 22 2008 

Google App Engine zoqui 11:12 pm

here are some few conversions needed to have the calendar events “when” objects converted into GAD DateTimeProperty model values.

The first thing we must keep in mind is: the calendar “when” object returns a list to be interacted, and get the calender event start and end time strings.  So, you  should have something like the piece of code below:

query = gdata.calendar.service.CalendarEventQuery(’default’, ‘private’, ‘full’, text_query)

feed = calendar_service.CalendarQuery(query)
for i, an_event in enumerate(feed.entry):
print ‘\t%s. %s’ % (i, an_event.title.text,)
print ‘\t\t%s. %s’ % (i, an_event.content.text,)
for a_when in an_event.when:
print ‘\t\tStart time: %s’ % (a_when.start_time,)
print ‘\t\tEnd time:   %s’ % (a_when.end_time,)

The start_time and end_time are simple strings in UTC format. Such values looks like something as “2008-05-23T08:30:10.000-03:00″. So you have the date: (2008-05-23), the time (08:30:10.000) and the time zone (-03:00 is one of the Brazilian zone). Once you don´t have a way to enter the seconds, milliseconds and the time zone in a single calendar event, the best thing to do is cut them out. So we will use the slice notation to do that.  Just keep the first 16 characters from the datetime string  [:16], and them proceed with the convertion using the strptime datetime function. This function parses a string input to a datetime object based on a given string format.

Take a look at this simple example:

class DateTime(db.Model):
when = db.DateTimeProperty(auto_now_add=False, required=False)

aDateTime = DateTime()
aDateTime.when = datetime.datetime.strptime(w.start_time[:16],”%Y-%m-%dT%H:%M”)

 

Hands-On #6 Setting up GData for Google Appengine Tuesday, May 6 2008 

Google App Engine zoqui 10:25 pm

There are some important updates need for having the SDK 1.0.2 and GData API 1.0.13 properly working.

  • Configure the GData libraries:
    In this task list I´m considering that your google appengine installation path is:
    C:\Program Files\Google\google_appengine\. Please adjust this piece of information if it does not match with your location.
  • Download the latest gdata-python-client file and uncompress its content in a temporary folder
  • Copy the entire src folder to C:\Program Files\Google\google_appengine\lib folder
  • Rename the src folder to gdata-python-client
  • Edit the urlfetch.py file located at:
    C:\Arquivos de programas\Google\google_appengine\lib\gdata-python-client\gdata\urlfetch.py
  • replace line 153 content from
    return self.headers[name]
    to
    return self.headers[name.lower()]
  • Replace your C:\Arquivos de programas\Google\google_appengine\google\appengine\api\urlfetch_stub.py by this file hacked urlfetch_stub.py file according to the AppDevEngine Issue 341
  • Edit the root dev_appserver.py located at
    C:\Program Files\Google\google_appengine\dev_appserver.py
  • Add a new line after line 43 with the following content:
    os.path.join(DIR_PATH, ‘lib’, ‘gdata-python-client’),The complete block must look like this:EXTRA_PATHS = [
    DIR_PATH,
    os.path.join(DIR_PATH, 'lib', 'django'),
    os.path.join(DIR_PATH, 'lib', 'webob'),
    os.path.join(DIR_PATH, 'lib', 'gdata-python-client'),
    os.path.join(DIR_PATH, 'lib', 'yaml', 'lib'),
    ]
  • save and close this file
  • Edit the root dev_appserver.py located at
    C:\Arquivos de programas\Google\google_appengine\google\appengine\tools\dev_appserver.py
  • “Change lines 1140-1141 of dev_appserver.py from:if (file_type != self._imp.C_BUILTIN and
    not FakeFile.IsFileAccessible(pathname)):to:

    if (file_type != self._imp.C_BUILTIN and
    file_type != self._imp.C_EXTENSION and
    not FakeFile.IsFileAccessible(pathname))”

    The dev_appserver.py file can be located at <Installation dir>\Google
