All arguments that are passed when running your script will be placed in sys.argv. You have to import sys first. And then go through the arguments as you would like to. You might consider counting how many arguments you have to decide what to do. And note that the first argument is always the name of your script.

cqlsh and cli both default to CL.ONE. I suspect the difference is actually that your cqlsh query says "select all the users" while a "get" in the cli is "select exactly one user."

Did you update djangoappengine without updating django-nonrel and djangotoolbox? While I haven't upgraded to GAE 1.7.4 yet, I'm running 1.7.2 with no problems. I suspect your problem is not related to the GAE SDK but rather your django-nonrel installation has mismatching pieces.

What about this?: Change the windows share to point to an actual Linux directory reserved for the purpose. Then, with simple Linux scripts, you can readily determine if any files there have any writers. Once there is a file not being written to, copy it to the windows folder—if that is where it needs to be.

If your program is *nix-specific, I suppose your best bet is parsing the output of mount command. It gives you mount points, user names, and FS names. Of them you could filter points mounted or at least writable by the current user, with a right FS on it (possibly vfat?).

There is no way for a Windows Store app to trigger a system reboot, neither can it run a Python script unless you implement a Python interperter inside your app. Windows Store apps run in their own sandbox and have very limited means of communication with the rest of the system.

I already have a web application in written in Python 2 that runs over WSGI (specifically, OpenERP web server). I would like to write a new web application that would run on the same server (Apache 2 on Ubuntu), but using WSGI and Python 3. The two applications would be on different ports. Is that possible?

You could try not using the eclipse import feature. Within Eclipse, create a new PyDev GAE project, and then you can copy in your existing files.

Use Tornado to just receive non-blocking requests. To do the actual XML processing you can then spawn another process or use an async task processor like celery. Using celery would facilitate easy scaling of your system in future. In fact with this model you'll just need one Tornado instance. @Eren - I don't think that...

The script runs through a few different websites, scans them for new material, and either grabs .mp3 files from them or likes songs on youtube based on their content.

You can setup a filter driver which can act in two ways: (1) modify the flags when the file is opened, and (2) it can capture the data when it's written to the file and save a copy of the data elsewhere. This approach is much more lightweight and efficient than volume shadow copy service, mentioned in comments, howeve...

No, there is no automated way where async Url Fetch would store data automatically to memcache on completion. You have to do it in your code, but this defeats what you are trying to do. Also remember that memcache is volatile and it's content can be purged at any time.

Unfortunately no. You can remotely connect to your Linux server via Remote System Explorer (RSE). But can't use it as a remote interpreter. I use Pycharm. You can use the free Community Edition or the Professional Edition for which you have to pay for it. It is not that expensive and it has been working great for me.

pip install -t lib package_name lib: the location for third party libraries Then you are good to use this package like a normal library you use from ipython or terminal.

The myScript.py was for the 2.5 runtime, the model for invoking apps with 2.7 runtime normally utilises the myScript.app method. Have a look at the age of the tutorials and also what Python runtime they have configured in their app.yaml.

Do not try to uninstall the pre-installed Python. Install other Python interpreters side by side (in different directories). You may come across an option to choose the default Python interpreter for your system. Don't change that from the pre-installed one, as that may break some important scripts used by the system. ...

I've noticed that some programs (e.g. hg) allow the user to tab-complete specific parts of the command. For example, if, in an hg repository working directory, I type: hg qpush --move b8<TAB> It will try to complete the command with any mercurial patches in my patch queue that start with "b8". What I'd like to do is i...

One solution I am currently considering: Add NewAppDelegate.m/h file that subclasses AppDelegate. This subclass, does what I want, and then calls the super methods. Find/replace AppDelegate with NewAppDelegate.m.h in main.m This seems pretty simple and robust. Thoughts on this? Will this work for all/most projects?

The error message you mention is typical on lxml when the libxml2 and/or libxslt libraries are not installed for it to link with. For whatev...
