There are numerous problems with threads in Python, but Python can work around almost all of these issues with coroutines, which let you have many seemingly simultaneous functions in your Python programs. Brett Slatkin discusses coroutines in this excerpt from Effective Python: 59 Specific Ways to Write Better Python.

A string is simply a sequence of characters. Like most entities in Ruby, strings are first-class objects. In everyday programming, we need to manipulate strings in many ways. We want to concatenate strings, tokenize them, analyze them, perform searches and substitutions, and more. In this chapter from The Ruby Way: Solutions and Techniques in Ruby Programming, 3rd Edition, Hal Fulton and André Arko show you how Ruby makes most of these tasks easy.

This chapter from A Practical Guide to Ubuntu Linux, 4th Edition takes a close look at the shell and explains how to use some of its features. It discusses command-line syntax and describes how the shell processes a command line and initiates execution of a program. This chapter also explains how to redirect input to and output from a command, construct pipelines and filters on the command line, and run a command in the background. The final section covers filename expansion and explains how you can use this feature in your everyday work.

A few months back I wrote a post titled "Why Open Source Matters: Musings from OSCON 2014". The post covered five reasons why Open Source matters. Those reasons were/are:


  1. Code, Glitches and Open Source Security
  2. Open Source Software
  3. GitHub
  4. The Stringent Control of Proprietary Software
  5. The Endless Ability to Test, Play and Alter

While those reasons still ring true, I want to use this space to center in on another topic speaking to why Open Source and OSS matters more than ever: project management and time constraints.

For the past week or so, Hong Kong has erupted with peaceful demonstrations advocating for the ousting of the Chinese premiere and the right to peacefully and openly elect his replacement. While the Chinese premiere, Xi Jinping, looks to be going nowhere one thing has become clear - the mobile devices and Internet connections which helped to grow the nightly demonstrations are quietly suffering an inward meta problem - malware, viruses and fake applications.

As mobile platforms become more prominent and are used more robustly to organize, carry out financial transactions and conduct daily personal business, the time has come to address mobile malware and fake applications.
