Suse Linux on the Asus l5800c   13 Jan 05
[print link all ]
I’ve got a shiny new Asus 5800 laptop, running SuSe linux 8.2 on it. Most stuff works straight away from the installation DVD. The wireless lan does not work (its’ a broadcom, and I read somewhere it is not supported at all under linux) and it is better to turn ACPI off with the kernel option ‘acpi=off’ at boot, otherwise the machine will overheat and shutdown.

With some work X and the gigabit network card operate properly.

XF86Config

Forget about using Yast to configurate X, because it makes a mess of it, do the X configuration manually.

Linksys gigabit ethernet card

The linksys card has to be compiled into the kernel separately, but this is easily done. Install the ‘kernel sources’ package, go (as uesr root ) to /usr/src/linux and type ‘make oldconfig’, so that the current system configuration is represented in the kernel configuration. Then unzip the linksys install script somewhere (e.g. in /root/) and run it. The install script takes care of everything for you - it checks system prerequisites, and compiles the ethernet driver module so it fits with your kernel.

After compiling the kernel module (you don’t need to reboot like in Windows :-) ), do ‘modprobe sk98lin’ and ‘ifup eth0’ and everything should work as usual. At home and everywhere at clients, I use ‘dhcpcd’ to the rest of my network configuration for me, so that’s no effort either.

I finally got it to work without overheating. Add ‘acpi=off’ and ‘noapic’ to the grub command line (in /boot/grub/menu.lst) .

Writing for the web, a tale of two contents...   12 Jan 05
[print link all ]
Programming on and off on an open source content management system, and using web-based content management systems on various occasions, I can’t help but wonder why I sometimes find them easy to use, and at other times a burden. After several years of writing for the web, I still have not found a way that does not get in the way of my writing process. Maybe this blogging software is a solution, maybe not. Let me describe some of my struggles:

Edit Text-files offline

The system I’m using for this piece (RubLog) is somewhat of a compromise. I write the article offline, using whatever text-editor I prefer, can commit the text to CVS (a version management system) if I desire, and let RubLog publish it directly from CVS. The advantage being, I can edit it wherever I am with my laptop and the text-file is accesible to any tools I might have on my laptop, such as a spelling checker if I’m not too lazy to use one. The other side of the coin is, if I spot an error in the text while reading the web-site, I cannot directly correct it, but have to go back to the text-editor to modify it and commit the new version to CVS.

Edit text-files and document objects online

Other systems, such as ZWiki and Itor (on which I’m programming myself) accept changes only through a web-browser. This makes it relatively straight-forward to correct typos - just open the web-page that needs to be changed, click ‘edit’ and presto… I can make my change directly, and version management (if any) is handled for me by the system. Click ‘save’ and I can see what the page now looks like. Not exactly WYSIWYG, but it provides me with fairly rapid feedback. This coin also has a flip-side: I have to be online to edit the text, and am constrained in editing possibilities by the simple text-boxes web-browsers offer.

Use a word-processor

One nagging thing RubLog, Itor and Zope have in common, is they are not fully WYSIWIG like my word-processor is. If I want to get an idea down fast, including pictures, I grab Open-Office Writer and Open-Office Draw. I can simply add titles, quickly create drawings, and include the drawings in the article. While I do that, I see what I am doing, because Open-Office is WYSIWYG, and does not need a separate rendering step after creating something. I currently like to write articles around a DiagramOfEffects (DOE). I usually start with a diagram, and describe that in the article. As the writing progresses, the diagram evolves. With a word-processor, I can add and modify diagrams rapidly. For a web-site, I’ll have to manually render the diagram to a bitmap. For every change to the diagram, rendering is required. Needless to say, I won’t start such an article with any of the text-based systems.

Another disadvantage of starting off the web, is that printing web-pages is still a nightmare, as I recently re-discovered when we tried to print registration forms for xp-day_benelux. So for readers who’d like a hardcopy, I’ll have to create a PDF from a separate document. Now I have two different articles… I’m unlikely to do this, If I ever intend to change anything to either of these articles.

render the word-processor text to HTML and PDF…

Now for the flip-side.… Although writing and drawing with OpenOffice is easy, rendering for the web leaves something to be desired. The easiest thing to do, is convert the document to PDF tm (PortableDocumentFormat) and upload it to the site. Most people have a PDF reader, and many search-engines index it. The advantage of this approach is, that it’s fast and easy :just choose ‘print to PDF’ when using OpenOffice in combination with Linux, it’s easily printable (unlike web-pages) for readers and the layout as written is preserved. The disadvantage is, that it isn’t a web-page, so it doesn’t integrate with the remainder of a web-site and doesn’t lend itself well to using hyperlinks. OpenOffice does render to HTML, but creates HTML with a horrible layout and duplicated style and font tags for every paragraph. The WYSIWIG nature applies to printed documents… Carefully added whitespace to put a diagram at the top of a paper-page leaves empty spaces that look ugly on a web-page. Specifying exact fonts to be used is inconvenient, as the web-site containing the document has to specify the style…

Where does this lead?

So for now, I guess I’ll continue to compromise. Write short rants like these with a text-based system, and write longer articles with pictures with OpenOffice, which I subsequently covert to HTML if I’m not too lazy.

That’s what I thought…

After writing this rant, I thought it’s time to get my act together and make my favourite way of writing articles of a few pages with pictures more comfortable for myself. This resulted in a simple program to remove extranous tags such as <FONT> from the html generated by OpenOfice . See TagCleaner for the result.

Bug Me... Not   12 Jan 05

Are you also annoyed by more and more websites wanting your personal details, often with no good reasons? Do you also have trouble remembering all those username/password combinations?

This week, I stumbled across bugmenot, where people can share logins for all kinds of sites. E.g. this one for soundclick, an online music site. I like to listen to fellow amateur composers, but I categorically refuse to register for these sites. There are too many, and i don't see what value registering provides me...

Unlike some other sites of course, where registering does provide value. For instance, forums such as synthforum.nl where registration makes it easy to follow who says what. bugmenot allows me to decide when I find it valuable enough to register, and when not.

Freedom of Speech killed again in the Netherlands   12 Jan 05
[print link all ]
For the second time in a few years, we witness a cold-blooded politically motivated assassination. Tuesday, Theo Van Gogh, cinematographer, columnist and generally recognized enfant terrible was shot in broad daylight in Amsterdam. Theo was an expert in ranting, not taking into account the feelings of others.

I did not necessarily agree with his views or the way he treated other people, I do however appreciate his ongoing efforts to stir up dialogue and debate about issues in our society. If someone feels attacked, use a pen or the law to react, not a gun...

Welcome to Rants and Ruminations, an irregularly appearing column by Willem van den Ende   10 Jan 05
[print link all ]
(updated January 6 2005).

Here you can find my ruminations on (agile) software development practice, systems thinking, as well as rants against ‘the hype du jour’ and sometimes system administration tips. I call it a ‘column’ as that is what this form has been called by (dutch) newspapers for a long time. On the web, it is hyped as ‘new’ and is often called a blog.

You can find contact details and more information on my professional activities at www.willemvandenende.com .

About the software serving this column

This site is running on a combination of Apache and RubLog, a piece of software created by Dave Thomas. If you want to use this software, you can download the source code and installation instructions from rubyforge RubLog is a simple file-based web log/wiki. It has a few distinguishing features:

  • It accepts input in a variety of markup formats. HTML, plain text, and RDoc formats are supplied by default, along with a handler for Usemod wikis. More can be added without much effort (this file is in RDoc format)
  • It works from conventional files and from CVS/RCS repositories. This is useful is multiple people are using the same blog: have them check stuff into CVS, and point the blog software at the repository.
  • It supports category-based and time-based access (and combinations of the two).
  • Output styles are pluggable: a standard example and a style to support printable documents are provided.
  • It supports WikiWord-style links between articles (in RDoc mode).

Brands as Living Systems   11 Aug 04
[print link all ]
Johnny Moore is discussing Brands as Living Systems. He talks about companies wishing for word of mouth, but not really word of mouth:
They distrust spontaneity because it threatens the perfection of their formula for how things should be. It's one example of the reverence for the abstract and the material, over the relationship and the people (more on this soon). It leads to the deadening formulaic "have a nice day" customer service instead of allowing human beings the possibility of creating some fun together in a way that works for them in the moment.

Developing software products has similar problems: do you really really want user involvement, or do you only want to develop the product in a formulaic way?

If you follow the first road, you could get some living software, that lasts a long time, because the users get to live in the software, and become inhabitants, rather than just users. If the inhabitants really feel they have an influence of where the software is going, you might get viral marketing. This approach is scary, since it forces the product developer to relinquish some control over the product to the inhabitants.

The second approach doesn't prevent success: the pre-defined vision doesn't change much, so it is probably easier to create pre-defined marketing material for it. If the formula doesn't stick, you're in trouble though. You also risk continuing friction between your vision and that of the users.

Reframing information overload   05 Aug 04
[print link all ]
Laurent Bossavit writes about Problem-picking patterns:
In complex situations, such as software projects and the teams that work on them, there's never such a thing as "the problem". The sense that something is wrong may be the start of a break with routine - the start of a problem-solving process.

From the list, I prefer to reinforce what works, to compensate for natural tendencies to think in negative ways about problems.

Another favourite of mine (although I'm not quite sure if it fits in Laurent's list), is Reframing - taking a different perspective so the problems at hand disappear and the situation looks entirely different. Marc Evers pointed me to a blog entry by Ton Zijlstra about information overload, Every Signal starts out as Noise which contains this example:

there is no such thing as information overload. It does not exist.

When trains were first introduced passengers suffered from jet-lag like symptoms, even at speeds as low as 20 km/h. Most likely because for the first time sensory input became asynchronous. What you heard and smelled (the train, people in the car with you) did not coincide with what you saw (the landscape passing by). We adapted, we have to do so now.
