Python Generators for System Administrators

by Leave a Comment

Python logoGenerator functions and Python. Doing your administrative stuff faster.

Often when I need to monitor something on one of my linux servers, I always gravitate towards these papers. I always forget how to use them, so putting them here is for me as much as it is for you. Go though the PDF presentation about Python Generators for System Administrators. and fiddle around with the example code. I’m pretty sure you can find stuff you need to to and you will be amazed of the speed of the code. It took a while for me to wrap my thick head around it, but the end result is great!

Flac, the best choice

Audio Engineering Pioneer John Meyer: Stop Chasing The Next Big Thing, And Go With Flac Instead — Tech News And Analysis:

John Meyer may be making really expensive loudspeakers, but when it comes to high-end audio, the audio engineering pioneer prefers free. FLAC, the open source audio format developed by Grateful Dead fans to trade bootleg recordings, is “the perfect format” for music aficionados looking for higher-resolution audio, Meyer told me during a recent interview. And to him, any company pushing trying to make a buck with selling upsampled music is just out to sell snake oil. “It’s tricking people who don’t know enough about technology,” he said.

I couldn’t agree more. We don’t need more formats. FLAC handless lossless compressed music without an hitch. Been using it for years and have my entire record collection in FLAC. I’m working on having my FLAC-encoded music in my car as well! Whohoo!

Nix Color Sensor by Matthew Sheridan — Kickstarter

Nix Color Sensor by Matthew Sheridan — Kickstarter:

Nix is a patent pending device that allows anyone to become a color expert. Just grab Nix from your pocket, purse, or bag, touch it to an object and magically watch the exact color appear on your iPhone, Android, PC, or Mac. Once scanned, you can keep palettes of your favorite colors, match the color to real life pigments, and even receive directions to the nearest store where you can purchase the color.

This looks like a cool project. And it’s open source! I wonder if it is accurate enough for car paint etc?

Adafruit TRINKET – Mini Microcontroller

Adafruit TRINKET – Mini Microcontroller – 3.3V and 5.5V versions:

It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power.

A cool cheap little Arduino compatible board for smaller projects. The 3.3V version runs at 8MHz and the 5V version can run at 8 or 16MHz. It has five I/O pins available and comes with 8kb of memory. It can be programmed with AVRDude or the Arduino IDE after some small modifications. Looks great!
