This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
def my_func(): | |
return "embedding?" |
#!/bin/bash | |
# | |
# Example of how to parse short/long options with 'getopt' | |
# | |
OPTS=`getopt -o vhns: --long verbose,dry-run,help,stack-size: -n 'parse-options' -- "$@"` | |
if [ $? != 0 ] ; then echo "Failed parsing options." >&2 ; exit 1 ; fi | |
echo "$OPTS" |
#!/bin/sh | |

"""{escher} -- one-file key-value storage. | |
What? | |
This is a toy application to manage persistent key-value string data. | |
The file {escher} is *both* the application and its data. | |
When you run any of the commands below, the file will be executed and, | |
after data change, it will rewrite itself with updated data. | |
You can copy the file with whatever name to create multiple datasets. |
One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.
Most workflows make the following compromises:
Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure
flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying

Bluetooth/Pyjnius example | |
========================= | |
This was used to send some bytes to an arduino via bluetooth. | |
The app must have BLUETOOTH and BLUETOOTH_ADMIN permissions (well, i didn't | |
tested without BLUETOOTH_ADMIN, maybe it works.) | |
Connect your device to your phone, via the bluetooth menu. After the | |
pairing is done, you'll be able to use it in the app. |
