Then, the topic shifts to the problems of project management as Johanna tries to answer a tough question such as, "What is the greatest mistake you see project managers do most often?" which leads into an interesting discussion about multi-projecting and why it can pose a problem for your projects. Also, more interesting advice from Johanna emerges when asked to give advice for new team-leaders/managers Johanna also talks about her new book: Hiring The Best Knowledge Workers, Techies & Nerds. And why she wrote it in the first place. To finish it all off Johanna answers one of the questions each project manager should ask themselves every once in a while: "What is the worst mistake youve done as a manager?"

Johanna Rothman is a well-known consultant, speaker, and author on managing high-technology product development.

The key to become a good hacker is to work on what you love! :-)

 Finally, after what seemed to be an endless series
 of release candidates, I am happy to announce the
 final release of version 182-14. Happy New Year!

 This release of the One-Click Ruby Installer for
 Windows is built from Ruby 1.8.2 final. It includes
 OpenSSL, and upgrades RubyGems and FreeRIDE to their
 latest versions.

 You can download this release from:

This program allows you to record the output of any standard OSS program (one that uses /dev/dsp for sound) without having to modify or recompile the program. It uses the same idea as the esddsp wrapper from the Enlightened Sound Daemon (in fact, vsound is based on esddsp). That is, it preloads a library that intercepts calls to open /dev/dsp, and instead returns a handle to a normal file. It also intercepts ioctl’s on that file handle and logs them, to help convert the audio data from its raw form. Vsound then uses sox to convert the raw data to the desired file format.

The upshoot of this is that instead of playing sound to the sound card in your computer, the data is recorded to a file. This is similar to if you connected a loopback cable to the line in and line out jacks on your sound card, but no DA or AD conversions take place, so quality is not lost.

One use of vsound is to help convert real audio files to some other format. Since the real audio format is proprietary, and all we have is a player, we can use the vsound to create a wave file like so:

 vsound -t -f /data/dvdburn/LL2/s2.wav  realplay rtsp://18.39.0.30/ailab/mit-ll2-s2-09nov02-80k.rm

  The final 1.8.2 will be out on December 25th (JST), unless any
  critical bugs will be found.

Apparently, this has been believed by many as a hoax, and so has been linked to the famous Alan Sokal hoax (the paper "Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity").

However I think it’s more like: a serious article written in a tongue-in-cheek style and talking about an unusual topic.

Other authors i know who are writing about postmodern programming, are Larry Wall (Perl) and Richard Gabriel (new online book "Patterns of Software"). These days I am attempting to read the latter.

Richard Gabriel’s work on software patterns, and for that matter, all the work on software patterns for the last decade, has been tremendously influenced by a book supposedly on Architecture (!!!), by Christopher Alexander, called "The Timeless Way of Building".

Both C.Alexander and R.P.Gabriel spend a lot of time on an elusive concept they call "Quality", which I immediately connected to Robert Pirsig’s "Zen And The Art of Motorcycle Maintenance" (1976), a classic I finally read this year. The connection between the two is quite large (Pirsig’s book even more revolves around that "Quality" thing). It has to do with attempting to define the undefinable, in particular, those aspects of a thing that make it good and/or beautiful but that, trying to approach them from a formal standpoint, slip through our fingers.

There are a bunch of other interesting aspects (IMHO) in all of those texts.

It comes with Gnome 2.8 and a 2.6 Kernel. The overall install was amazingly simple. Download it.

Using Ruby and SQLite to create Linux clusters that take advantage of idle nodes and bypass expensive software solutions.

My friend Dave Clements always is game for a brainstorming session, especially if I’m buying the coffee. Recently, we met at the usual place and I explained my problem to him over the first cup. My office had a bunch of Linux nodes sitting idle and a stack of work lined up for them, but we had no way to distribute the work to them. Plus, the deadline for project completion loomed over us.

Over the second cup of coffee, I related how I had evaluated several packages, such as openMosix and Sun’s Grid Engine, but ultimately had decided against them. It all came down to this: I wanted something leaner than everything I’d seen, something fast and easy, not a giant software system that would require weeks of work to install and configure.

After the third cup of coffee, we had it: Why not simply create an NFS-mounted priority queue and let nodes pull jobs from it as fast as they could? No scheduler, no process migration, no central controller, no kernel mods—simply a collection of compute nodes working as fast as possible to complete a list of tasks. But there was one big question: was accessing an NFS-mounted queue concurrently from many nodes possible to do safely? Armed with my favorite development tools—a brilliant IDE named Vim and the Ruby programming language—I aimed to find out. link

Every hour, 10x10 scans the RSS feeds of several leading international news sources, and performs an elaborate process of weighted linguistic analysis on the text contained in their top news stories. After this process, conclusions are automatically drawn about the hour’s most important words. The top 100 words are chosen, along with 100 corresponding images, culled from the source news stories. At the end of each day, month, and year, 10x10 looks back through its archives to conclude the top 100 words for the given time period. In this way, a constantly evolving record of our world is formed, based on prominent world events, without any human input.

I consider the mozex extention for Firefox a "must have." With mozex, I can edit textareas with vim and handle mailto links with mutt!

Mozex will also enable you to view html source in vim. link

You can edit your mozex prefs by typing about:config in Firefox.
