Python simple web server

The absolutely fastest way to get a simple web server up and running using Python 3, for development purposes.

cd my_web_root
python -m http.server

Or if you are on Python 2.x:

cd my_web_root
python -m SimpleHTTPServer 8000

Then just access http://your-ip:8000 to access the web server contents. Hit ctrl+c to exit.

Installing PySide into a virtualenv

I’ve been struggling to install a portable/relocatable virtualenv with PySide 1.2.2 for Python 2.7. On Windows, this works out of the box but it’s more difficult on Linux and OS X, although I came up with a patch for OS X. This guide will not go into detail on portability/relocatability and will merely touch upon how to get started with PySide in a virtualenv. It looks like PySide 1.2.3 will have substantial changes which will allow for easier portability/relocatability and I will make a post on that as soon as it is generally available.

Getting quick access to new Google Cloud SDK features

There is a two-week delay before gsutil gets updated with the latest and greatest. If you want to try the new stuff out, pip install the SDK!

sudo yum install gcc openssl-devel python-devel python-setuptools libffi-devel
sudo yum install python-pip
sudo pip install -U gsutil

Then execute gsutil like this:


To access beta (or even alpha) features of gcloud, execute gcloud like this:

gcloud beta compute instances ...

File copy progress window with PyQt/PySide and shutil

I recently wanted to show the progress of a file copy made from a python script (or actually, from a python script running inside of Maya and Nuke). First I looked to piggyback on the OS native ways of copying a file, but oddly enough it turned out there was no way of showing a progress bar when doing this.

3D rendering in the Google Cloud

Guest blogging for Google!

As a small design and visualization studio, we focus on creating beautiful 3D imagery – be it high-resolution product images or TV commercials. To successfully do this, we need to ensure we have access to enough rendering power, and at times, we find ourselves in a situation where our in-house render farm’s capacity isn’t cutting it. That’s where Google Compute Engine comes in.

Copying Maya to network share

If you would like to run a thin client installation of Maya, which means you run it off a network share rather from a local installation, you need to make sure to copy symlinks on Linux.
