Re: Django on Amazon EC2

[Jörn Paessler]

Hi Joshua,

we do not have public AMIs to offer, but if you logon to Amazon's  
Management Console and search for "django" under AMIs you find at  
least three public images:
<https://console.aws.amazon.com>

I reckon this should be a good start.

Re: Django on Amazon EC2

[Jörn Paessler]

Hi Joshua,

we have been hosting our django sites on EC2 for about 9 months now.

We are quite happy with it but there are some things you have to take  
care of:
- we recently had a downtime, because the host system crashed. We had  
a new instance up and running pretty fast but you have to keep in  
mind: there is no self-healing mechanism to e.g. broken HDD on EC2.  
You need to have a backup plan. An Amazon support employeee send me  
this reply afterwards:
"Instances depend on the health of the underlying host. The component  
that breaks most often are hard disks, so if the instance had any data  
stored on the disk, it may not be recoverable if there was a fatal  
failure, so moving an instance is not easily possible. In general, we  
recommend that you architect your system in a way so that a single  
instance failure does not disrupt the overall operation of your  
system. We also recommend keeping current backups."

Re: Do you code django with Komodo?

[Jörn Paessler]

Hi Brian,

thanks for your reply.

I also appreciate to see interest in a Komodo extension.

Since we come from the Zope world, we have years of experience with  
Python.
We also invested a lot of work and energy in the topic IDE for Zope: 
http://zamasing.com 
.
That's reason, why my head is full of ideas for a django IDE ;)

We have some experience in XUL and Firefox extensions. We published the
- Zope Toolbar: http://www.beyond-content.de/zope_lounge/zope_toolbar  
and
- Paessler Site Inspector: http://www.paessler.com/tools/psi
a few years ago.

Both of them are/contain XUL/JS driven FF toolbars.
I have no experience with the "Cross Plattform COM" (PyXPCOM)  
supported in Komodo yet. But I am also not sure if Python is the  
preferable language compared to JS. Since for the latter there are  
more examples to find (but also  just a few).

How should we proceed? Should we gather a list of ideas and features?

Have great day!

Best
Joern

I found this project at Google Code:
http://code.google.com/p/django-komodo-kit/

It doesn't seem to be too active, though :)

Does anbody know the project owner?

Re: Do you code django with Komodo?

[Jörn Paessler]

Hi,

on Windows I used to work with pydev/eclipse. Since it didn't run on  
Mac OS X so well, I switched to Komodo Edit first and purchased Komodo  
IDE later. The IDE offers support for Subversion and some class  
browsing functions.

What I also appreciate is the code completion support for some of the  
most popular AJAX frameworks. My favourite is jQuery.

The extensibility of Komodo in our beloved language Python is another  
plus.

BTW: would anybody be interested in contributing to a Komodo-Django  
extension with shortcuts to manage.py etc., modeling wizards and so on?

Best
Joern
