Dealing with Command Line Options in Python
I just wrote a bit of Python to generate some reports from the contents of a database. The one program that was more than just "display the data" was the one to print the transaction log. It included some sub-totals for various fields and paginated output.
The one task remaining was to give it some options. That is, to pass it some criteria that would modify the report. read more

A real gift this holiday season...delete it.
Can I vent here for a moment about well meaning, but clearly out-of-the-loop, friends who seem to think everything on the Internet, especially when it comes to safety, is a real situation that needs our attention and should be sent to every mailing list they are on?

StudioDave Does A Hardware Review And Meets Ubuntu 8.10
A few months ago I started sensing the need for a replacement for my aging and ailing HP Omnibook 4150. That machine's audio capabilities were negligible even with external hardware, but it had been serviceable for writing articles and as a portable MIDI composition environment. Alas, after years of travel and abuse the Omnibook's hard drive gasped its last breath of life. I had no fear for my data, the drive had been backed up, but clearly the time had come to buy a new portable computer.

If you have a substantial enough group of followers, inevitably, a few are paying attention most of the time, and you will get a handful of interesting responses to almost any question.

Open Source and the frustrations at end-of-life, and beyond
Over the years, I have turned to Linux and the Open Source community for a number of solutions to obscure and difficult problems. And, rarely, has the community let me down. But the community, like software development in general, has limited resources and sometimes limited interest.

Save the Libraries ? With Open Source
For some in the world of free software, libraries are things that you call, rather than visit. But the places where books are stored ? especially those that make them freely available to the public ? are important repositories of the world's knowledge, of relevance to all. So coders too should care about them alongside the other kind, and should be concerned that there is a threat to their ability to provide ready access to knowledge they have created themselves. The good news is that open source can save them.

Use the date Command to Measure Elapsed Time
When running bash scripts that take a long time to run
it's often useful to know how long it took for the script to run.
In addition to the overall run time, it's also often useful to
know how long certain parts of the script took to run.
The time command doesn't really help because it's meant
to time a single command, not a sequence of commands.
