How to show Stereo Mix in Windows 7 for Alienware M11x R2

When you want to record the system sounds directly (not from the microphone) in Windows 7, you need to have "Stereo Mix" in your list of recording devices (right click on the speaker icon on the task bar and choose "Recording devices"). A great application* of this is to record VoIP calls** such as those done on Skype or Google Talk/Google Voice
*You will need a good audio recording application such as Audacity (free).
**Check out this page before recording phone calls to learn about how legal that actually is where you live: http://en.wikipedia.org/wiki/Telephone_recording_laws#United_States

To display the Stereo Mix "device" in an Alienware M11x R2 you need to reinstall the original driver from the manufacturer, since Windows probably already updated the driver to its own version which doesn't support this functionality.

You can get the file here: http://www.dell.com/support/drivers/us/en/19/product/alienware-m11x-r2#anchorProductAudio, the current version distributed by DELL is 6.0.1.6083. Over here it seems you can also find older and newer versions directly from Realtek: http://www.realtek.cz/realtek-download.php?realtek=ALC665&system=6 *
*I didn't need to do that, 6.0.1.6083 worked.

This is how your Recoding devices list will look like after reinstalling and restarting Windows*:
*Actually you first need to right click the list, make sure the disabled devices are being displayed, and then right Stereo Mix to Enable it first.


Now Stereo Mix should be listed when selecting a recording device in your audio software :) Happy recording!

sqlalchemy ProgrammingError can't adapt type numpy.float64 - Python troubleshooting

Are you getting a

sqlalchemy.exc.ProgrammingError: (ProgrammingError) can't adapt type 'numpy.float64'
???

It's because psycopg (psycopg2) - which is used inherently by SQL Alchemy but if you're just dealing directly with alchemy you might not know this - has no idea how to make the numpy.core.numerictypes.float64 (complete type path: another thing they don't tell you) a string for SQL querying.

Simple solution, add:

# solution by Jorge Orpinel found at rehalcon.blogspotcom
import numpy
from psycopg2.extensions import register_adapter, AsIs
def addapt_numpy_float64(numpy_float64):
return AsIs(numpy_float64)
register_adapter(numpy.float64, addapt_numpy_float64)
somewhere in the program.

For a more complete reference of the problem see http://initd.org/psycopg/docs/advanced.html#adapting-new-python-types-to-sql-syntax

Dockerize your Django App (for local development on macOS)

I'm writing this guide on how to containerize an existing (simple) Python Django App into Docker for local development since this is how I learned to to develop with Docker, seeing that the existing django images and guides seem to focus on new projects.

For more complete (production-level) stack guides you can refer to Real Python's Django Development with Docker Compose and Machine or transposedmessenger's Deploying Cookiecutter-Django with Docker-Compose.

Pre-requisitesAn existing Django app which you can run locally (directly or in Virtualenv). We will run the local dev server with manage.py runserver.A requirements.txt file with the app dependencies, as is standard for Python projects; including MySQL-python.Working local MySQL server and existing database. (This guide could easily be adapted for other SQL engines such as Postgres.)Install Docker. You can see Docker as a virtual machine running Linux on top of your OS ("the host"), which in turn can run con…

Mapa del Metrobus de la Ciudad de México

Update: Por fin el Gobierno hizo su chamba luego de años de que mi mapa fuera el único en Google Maps. Hoy (05-11-2013) me percaté que en www.metrobus.df.gob.mx/mapa.html (solo con "www"...) se puede apreciar ya este mapa (zoom centrado en centro de la ciudad):

Para quien prefiera los iconos que yo utilicé, aquí dejo la última versión que actualicé (hasta línea 4 y proyecto de línea 5): En mi post "Mapa del Metrobus en Google Maps" publiqué el mapa del metrobus en Abril dl 2009. Ahora que hay más estaciones y más líneas, es necsaria esta actualización.
Incluye íneas 1 a 4 (actual a Junio 13 del 2012). La descripción de cada estación incluye correspondencias con otras líneas de MB y con el meto.
Además quiciera es incluir el ten ligero, las rutas/paradas del turibus, y algunas rutas de RTP - y tal vez el ten suburbano.
