• The framework: Ruby on Rails
• The favored webserver: lighttpd with FastCGI
• An embedded database: SQLite

Locomotive includes the Ruby MySQL and PostgreSQL bindings. If you have MySQL/PostgreSQL installed, or want to use them, Locomotive is ready.

Locomotive will be nice to your existing rails installation as Locomotive is entirely self-contained.

Propositions for enhancements are welcome…

 >FWIW, I didn't find it insulting.  I was offering my (somewhat
 >> educated) viewpoint.

 I knew that education would get you in trouble someday.
 If you were a dropout like some of us, we wouldn't be having all
 these communication problems.

 That's why I like to work with people who know they're idiots. It's
 just so much easier on all of us.

 If they're an idiot and they know it, I can work with them.

 If they know they're an idiot and they turn out to be smart, so much
 the better.

 If they're an idiot and don't know it, I know I don't want to work
 with them.

 And if they're not an idiot and they know they're not an idiot, I
 don't want to work with them. Why make someone like that suffer?
 After all you'd have to be an idiot to want to work with me.

 The C Programmer
    God consults with the C programmer on every major issue. (As anyone
    who study's processor design knows all to well.)
        The C programmer can walk on water.

 The VB Programmer
    The VB programmer does lunch with God every day.
    He is an olympic class swimmer.

 The Turbo Pascal Programmer
    The Turbo Pascal programmer occasionally has a word with God.
    He can swim pretty well.

 The Fortran Programmer
    The Fortran programmer sometimes catches a glimpse of God.
    He manages to keep himself afloat in shallow water.

 The QBASIC Programmer
   The QBASIC programmer knows who God is.
   He has trouble avoiding drowning in his own bathtub.

 The LOGO Progammer
   About the only thing a Logo programmer knows about GOD is that the
   word is short enough for him to sound out, but he has trouble spelling
   it.
   He needs someone else to cerry him across the water for him.

 The Assembly Language Programmer
   The assembly language programmer is God.
   He parts the water when he wishes to cross it.

 The Forth Programmer
   The Forth programmer don't view ever river he comes across as a
   challenge to his religious faith and just walks across the bridge.

 October 2005: Bigger Teams Not Always Better
 By Amit Asaravala

 >>>> MO' DEVELOPERS, MO' PROBLEMS?

 Thinking about assigning more developers to a project
 to accelerate your schedule? Be careful. Putting a large
 team on the job could cause you more trouble than it's
 worth, according to a new study by software estimation
 and analytics vendor QSM.

 The study, based on data that QSM collected from 564
 information systems projects completed since 2002,
 revealed that large teams don't complete projects much
 faster than small teams, though they cost much more. In
 particular, teams with 34 people on average completed a
 100,000-line project in 5.6 months at a cost of $2.1
 million, while teams of four people on average took
 about two weeks longer but cost just $294,000. Thus,
 shaving two weeks off the schedule cost some companies
 as much as $1.84 million.

 Why such disproportionate production rates? Blame it
 on the bugs. The larger teams produced more than five
 times as many bugs as the smaller teams, which required
 the teams to reexamine their code more often, according
 to QSM. In the end, this ate into a large portion of
 the time saved by having more developers turn out more
 code per day.

 But before you decide to cut your team back to just
 four people, consider this: The size of the small team
 in the study was just an average, and QSM readily admits
 that it's saving the question of "optimum" team size for
 a future study.

 Rather, the real lessons here are that you'd better be
 sure that accelerating your schedule by adding more
 developers is worth the extra cost, and that you should
 have realistic expectations about how many days you'll
 actually save by doing so.

Here’s a very interesting set of comments from Linus Torvalds and Theodore Tso on the problem with writing specs:

kerneltrap.org/node/5725

Here’s a great quote from Linus:

 The classic example of this is the OSI network model protocols.
 Classic spec-design, which had absolutely _zero_ relevance for the
 real world.We still talk about the seven layers model, because it's
 a convenient model for _discussion_, but that has absolutely zero to
 do with any real-life software engineering. In other words, it's a
 way to _talk_ about things, not to implement them.

 And that's important. Specs are a basis for _talking_about_ things.
 But they are _not_ a basis for implementing software.

And a good one from Ted Tso:

 In those cases, if you implement something which is religiously
 adherent to the specification, and it doesn't interoperate with the
 real world (i.e., everybody else, or some large part of the
 industry) --- do you claim that you are right because you are
 following the specification, and everyone else in the world is
 wrong? Or do you adapt to reality?

And another one from Linus:

 So don't talk about specs. Talk about working code that is
 _readable_ and _works_. There's an absolutely mindbogglingly huge
 difference between the two.

All heresy to the BDUF school of thought, of course. But relatively uncontroversial in the XP world. Interesting to see the parallel evolution.

A few months ago I did buy a mac mini. My excuse to my girl-friend was that it would make less noise than my hyper big server. The mac mini looks really nice and OS-X is cute, too. I got to admit, I do love the GUI and the poor fact that most things like WLAN, etc. seem to work out of the box. But the definite downside is that coming from Debian/Gentoo/Suse I got some expectations towards the development tools. Now I waste hours installing fink, etc. .. fighting with different philosophies, but I still enjoy the new journey.

It will take 5 years, as one has to get all right. The fast intuitive UI, the security, the marketing and many other things. Looking at a big company, most people only use:

• Browser
• Calendaring app
• Word
• Excel
• Powerpoint

Why did openoffice not have a wider impact so far? Can a web-based suite win without entering the "comopatability/file format" war?

Have a nice and long weekend. It’s the last two days of the Oktoberfest, so I am preparing for some beer.

 1. vncserver
 2. enter password
 3. remove all in  ~/.vnc/xstartup that is not needed
 4. work:
    DISPLAY=:1 R
 5. vncserver -kill :DISPLAYNUMBER_FROM_STEP_1

Thanks to Stefan!

"Let’s pretend I’ve decided to build a spice rack.

I’ve done small woodworking projects before, and I think I have a pretty good idea of what I need: some wood and a few basic tools: a tape measure, a saw, a level, and a hammer.

If I were going to build a whole house, rather than just a spice rack, I’d still need a tape measure, a saw, a level, and a hammer (among other things).

So I go to the hardware store to buy the tools, and I ask the sales clerk where I can find a hammer.

"A hammer?" he asks. "Nobody really buys hammers anymore. They’re kind of old fashioned."

Surprised at this development, I ask him why."

David Norfolk recently interviewed me regarding how I view XP and architecture. He started out quite skeptical, but I found his article balanced and thoughtful: www.theregister.co.uk/2005/09/11/beck_on_xp_architecture/

You have to love the irony here:

1) IBM drops Smalltalk, handing it to Instantiations:

www-306.ibm.com/software/awdtools/smalltalk/transition.html

2) Another part of IBM, focused on syndication technology, starts to realize that dynamic languages like Smalltalk are the wave of the future:
