Here's how to page reults from appengine query:

• get pager helper file
• i had to comment out the check for is issubclass since there's no db.polymodel.Polymodel. I haven't checked out whether there exists polymodel. It works for me since I subclass db.Model
• add these in my request handler:

          tt_query = PagerQuery(TekaTeki).order('-dcreated')
          prev, results, next = tt_query.fetch(1, bookmark)
  
          template_values = {'entry': results[0],
                              'next': next,
                              'prev': prev
                          }
          path = os.path.join(os.path.dirname(__file__), 'index.html')
          self.response.out.write(template.render(path, template_values))
  

• and in my index.html:

    {% if prev %}<a href="/?bookmark={{ prev }}">prev</a> {% endif %}| {% if next %}
  <a href="/?bookmark={{ next }}">next</a>{% endif %}
  

and we can now page through" the results accordingly.

'Twas a long weekend. Used to have a site that collects teka-teki or riddles since I don't know when. (98?)

Thought it'd be a great time to brush up on fb api and app engine.

So, did a model for teka-teki, and coded the handlers for all requests.

The end result? Have a look see , add more teka-teki or share funny ones with your friends.

To do:

• rating?
• voting?

Installing new paravirtualize guest on xen host:

  virt-install -p --accelerate --name x --ram 1000 --file /home/x/x.img --file-size 80 --nographics --location http://192.168.1.10/iso

Reading excel files:

  from xlrd import open_workbook
  wb = open_workbook('nyxls.xls')
  sheets = wb.sheets()
  sheet1 = sheets[0]
  sheet1.nrows #number of rows avail
  sheet1.ncols    #number of columns

  #and lots more methods that will help in reading xls
  #for writing xls, get xlwr

Gammu works with Huawei E220.

Here's my .gammurc:

  [gammu]
  port =/dev/ttyUSB0
  connection = at
  #connection = fbus
  #synchronizetime = yes
  logfile = 
  logformat = nothing
  #use_locking = yes
  gammuloc = 

Now we can do stuff with E220; e.g gammu --identify

But more fun to script things in python, so get python-gammu

Here's how to send sms:

  import gammu, time
  sm=gammu.StateMachine ()
  sm.ReadConfig ()
  sm.Init()
  smsc=sm.GetSMSC()
  msg='msg in a bottle'

  d={}
  d['Text'] = msg
  d['SMSC'] = smsc

  f=open('/tmp/numbers').read().split('\n')
  for i in f:
      d['Number']=i
      time.sleep(1)

Well, thought of moving to posterous, then tumbler, but I think why move.

So, back to where it all started.

Briefly:

• now on f12. upgraded from f11 without any problem
• chrome on linux (beta)
• zope2
• nginx
• new sites with fb connect. soon add gfc?
• raiders still suck, well jaMarcus sucks. and vikings and farve lost nfc championship.

More to come.

p/s - probably will move to a new server soonish.

Here's how to get chromium on fedora 11 (or other distros)

Follow the steps here

in a nutshell:

• get the latest build
• unzip, mkdir lib
• symlink a few libs
• export LD_LIBRARY_PATH=path/to/chrome/lib:$LD_LIBRARY_PATH
• ./chrome

we're done.

And yeah, it's fast. Compared to ff3.5? no idea yet.

Resource hog? no idea yet.

Got some time to myself and decided to upgrade my fedora 10 to fedora 11.

Big mistake. Upgrade has not been good for me; from f9 to f10. And now from f10 to f11.

The upgrade from dvd process went well. It's what happened after rebooting.

X don't work. So thought I'd do a yum update. Met ith "cannot import yum module".

Great. Realized that there were two python versions and python2.5 has everything intact. So:

  export PYTHONPATH=/usr/lib/python2.5/site-packages

Now yum worked. yum update pulled in 900+ packages ! (well that was my fault for installing lotsa stuff)

When yum finished, rebooted and was met with a blank screen.

Dang. Guessed that grub was screwed. Booted to rescue mode, ran grub-install, and rebooted again.

At last. Now everything works (I hope).

So, fresh install next time? I doubt it ;D

p/s - f11 dual monitor setup works :

  xrandr --output VGA1 --left-of LVDS1

Haven't yet booted with bootchart to compare boot time between f10 and f11.
