Python Sheds 2.x Skin

The much-anticipated next incarnation of the popular Python programming language — voted favorite scripting language in the 2008 Linux Journal Readers' Choice Awards — slithered onto the scene on Wednesday with the release of Python 3.0. Known popularly as Python 3000 or Py3k, Python 3.0 bears the distinction of being the first release in the language's history to deliberately break compatibility with previous versions. more>>

Cycles and Simplicities

Om Malik calls this "dave winer's best post of the year". I can't recall a better one, but ranking isn't what matters here. What matters is perspective and experience, and Dave has plenty of both. What he says is, more>>

Fedora Fishing for a Fresh Appellation

The naming conventions for Linux distributions are a many-splendored thing: Ubuntu's names are perhaps most well-known, owing to their ear-pleasing alliteration and the sheer number necessitated by the frequency of releases. Debian, too, is well known for naming the versions inhabiting the multi-tiered release system after characters from the Toy Story franchise — even down-to-business Gentoo is in on the games, with the 2008.0 release bearing the codename "It's got what plants crave." Now it's Fedora's turn at bat, with entries open on the nom de plume for Fedora 11. more>>

The Community Comes Through

As I wrote back on November 27, there is nothing more frustrating than trying to make software beyond its end-of-life work, and it is even more frustrating when it is really the best tool for the job. more>>

DIY RC FIY

I've always had a thing for remote control (RC) aircraft. The kid and I have several half-broken ones to prove it. So now I'm thinking about taking it to the next level. Literally. With a DIY Drone -- a kind of aerial robot. more>>

Running DOS Programs on Linux: Duke Nukem Lives!

If I play video games they're usually pretty low tech ones. One of the few games I miss from the old days is Duke Nukem, and I'm talking about the Duke before he went 3D. If you have an old DOS game that you'd like to run, or for that matter any old DOS program, check out DOSBox. Even if you don't have any DOS programs that you'd like to run, you might want to try downloading some of the old DOS games that are now available free online. more>>

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. more>>

openSUSE Ends EULA

Just as those of us in the U.S. were preparing to pop our turkeys in the oven, the hard-working fellows at the openSUSE Project — the community organization behind the openSUSE Linux distribution — were lifting the lid on their own creation: a brand new license for openSUSE 11.1 — that doesn't involve a EULA. 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? more>>

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. more>>

What Does Open Source Taste Like?

For those of you familiar with twitter, the "microblogging" social-networking tool, you know that it can be a fun way to gather data from a large group of people. 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. more>>

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. more>>

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. more>>

Mozilla McAdd-Ons: Over A Billion Served

There are few places one can go where a gleaming pair of yellow arches cannot be found proudly declaring some variant of "Over 99 Billion Served." Now browser-maker Mozilla has something in common with McDonaldland: As of last week, Mozilla has officially served up their billionth add-on. more>>

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. By using the %s format more>>
