Helpful Tips for Developers

I got this message trying to install from Xamarin Studio to multiple Android devices.  The fix that worked for me is

To switch to the branch you were on before the current one, type

When viewing a diff on github, if someone cleaned up whitespace and/or changed line endings, you can ignore that and just see the good stuff by appending ?w=1 on the query.

Like for example:

Work horses, who put their head down and do whatever they're told, and generally get things done.  They may not be the best problem solvers, but usually they can figure out a way to get it done.  They don't want to be promoted, they don't care about what they work on (well, to a certain extent), they just work.

Money hungry programmers - they learn the bare minimum to get the job done, are eager to be promoted and always overpromise and underdeliver... they cut corners wherever they can, their quality is usually bad or horrible, and they are the worst kind of programmer

The highly intelligent but unmotivated programmer - figures out the coolest ways to solve problems, and can calculate pi to the 20,000th digit in their head, but won't spend any time learning beyond their current problem.  Usually doesn't want to be promoted, but will become manager if it seems like the same type of work.

The knowledge thirsty programmer - Cannot stop learning no matter how hard he tries... always reading about the latest trends and trying as many of them out as possible.  May not be the smartest, but can almost always figure out a way to do something, or find someone else that already has and use that.

Just spent way too long researching this error.

The issue was that I had:

mapping.Map(x => x.Customer, "UserId")

instead of:

mapping.References(x => x.Customer, "UserId")

Ever since the gmail and mobile phones started showing email as threaded conversations, it's been hard to use a client that didn't.

If you're trying to figure out why a route isn't working, a quick way to see what it's doing is to open up a python shell and see what it's returning:

Download the correct version of setuptools (for your python version) from http://pypi.python.org/pypi/setuptools

$ sh setuptools-0.6c11-py2.7.egg

$ easy_install pip

I needed to see what endpoints my web app was hitting, and my trusty network tools (fiddler and chrome dev tools) weren't helping, because it was between the web server (IIS) and the endpoints (not the browser and web server).

After a little digging, I discovered Wireshark.  Using the following settings, I could see what the posts were:

Capture -> Options -> Capture Filter: HTTP TCP port (80)

Filter: (in the toolbar above the requests) http.request.method == "POST"

Hopefully this helps save someone a few minutes (hours) of searching just to get this info.

Also, to see the soap envelope (assuming it's hitting a soap endpoint), drill down into the data for:

Previously I showed how to (quickly) get a django linux box up and running.  Now it's time to update the settings to get static files served (correctly) with apache.

First, edit the config file, like:

vim /etc/apache2/sites-enabled/django

And add the following:

Alias /static /var/www/project/static <Location "/static">     SetHandler None </Location> 

Then edit your project settings file to reference the static folder

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'static') STATIC_URL = '/static/' STATICFILES_DIR = ( "/var/www/static",  ) 

And lastly, run collectstatic to map the files:

This one is so obvious I can't believe I didn't know it, but if you need to reset IIS on a different box, just run

I've been digging django and wanted to figure out a good way to host it, as well as mess with it in a linux environment.  Most of my linux skill comes from hacking a western digital world book (to use as a torrent server), so I don't know too much...

The first thing I did was download a vm appliance, from turnkey, created just for django.  You'll also need vmware player (a free download with registration).

And I was done.  Go ahead, try it.

Another thing that will help is updating a few things.  To get the gcc compiler and other essentials, run:

apt-get install build-essential

To get python and django updated to latest (current 2.7.2 and 1.3) try the following:

$ wget http://www.python.org/ftp/python/2.7/Python-2.7.2.tgz $ tar xzf Python-2.7.tgz $ cd Python-2.7 $ ./configure --with-pth --with-dec-threads --with-signal-module --prefix=/opt/python-2.7 $ make $ make install

and then

$ rm /usr/bin/python $ ln -s /opt/python2.7/bin/python /usr/bin/python $  export PATH=/opt/python-2.7/bin:$PATH
