chris blogs: June 2004

28jun2004 · Paradise lost

On sunday, about 9 o’clock, paradise, my main developing and hacking box, finally crashed. I’m not fond of the exact reason. I left the room short ago, and when I came back, it was totally silent. Actually, first I thought something happened to my ears. Neither fan nor disk spun.

The most scary thing, however, was that my desktop still was there, shown on the monitor. When I tried to reboot, paradise wouldn’t do anything.

After swapping the PSU the next day, and trying a different CPU, I still couldn’t get it to work. It seems the mainboard died. This box ran stable for about the last two years. I have no idea what happened, I just hope nothing happened to the disks…

For the time I’m searching for a new mainboard, I can’t update this blog. I have chosen to keep it on paper for that—I hope rather short—period of time. Later, I’ll upload those physical entries.

Now, that I can’t program anymore, I hope I have enough time to read some books I still haven’t finished.

I really miss my music collection…

27jun2004 · md2html

I have been writing some simple tool to generate single HTML pages that don’t suck.

From the README:

Too often I wanted to put up some web page very quickly, and got very dissatified as I had to cope with the XML syntax (altough that gets easier with a proper editor, it’s still too much hassle.)

Besides, the resulting HTML used to look very ugly—there was no time to come up with a stylesheet.

md2html solves these two problems on this way:

  • The input file is written in Markdown, a very simple plain text format that is both easy to learn and to use. At the same time it allows for (optional) inclusion of HTML tags to get the full power of formatting.

  • md2html comes with a sample CSS stylesheet which gets included in the resulting HTML file to allow you to show it others without blushing. ;)

26jun2004 · Gmail revisited

I have been using Gmail for some days now, and there are some things that bug me:

  • You can’t mark all messages in the current folder as read. (All actions only work for the current page.)

  • Worst thing: All mails are shown in a variable-width font. Come on, most emails are plain text, like code (my mails include a lot of code, too). As such, many use fixed-width font editors to read and write them. It shouldn’t be too hard to add that to Gmail. In theory, a single line fix in the CSS. (I tried tracking down the CSS sheet of Gmail to override it locally, but got tangled up in a mess of Javascript and Frames.)

  • You can’t search using regular expressions.

  • You can’t add mail addresses in To: and Cc: to the address book automatically.

Else, Gmail works really fine for me. I have been reading ruby-talk with it for some days now, and find the threading support very useful.

24jun2004 · Real Life Markup Language (RLML)

Yesterday and today I implemented a parser for the Real Life Markup Language (RLML) invented by Paul Battley for Ruby.

RLML aims to “Make an alternative to XML that is simple to use for both man and machine.” You can read the provisional specification at http://po-ru.com/rlml/rlml.txt

So far, I have programmed a very low core, non validating API CoreParser, StreamParser, a more SAX-like streaming API, and TreeParser, a DOM-like interface. Each of these builds on the other ones.

For example, this XML document:

<note>
  <to>Tove</to>
  <from>Jani</from>
  <heading>Reminder</heading>
  <body>Don't forget me this weekend!</body>
</note>

would look like that in RLML:

rlml/iso-8859-1
note
{
    to{Tove} from{Jani} heading{Reminder}
    body{Don't forget me this weekend!}
}

These are the events in CoreParser:

[:encoding, "iso-8859-1"], [:start_tag, "note"],
[:start_tag, "to"], [:idata, "Tove"], [:end_tag],
[:start_tag, "from"], [:idata, "Jani"], [:end_tag],
[:start_tag, "heading"], [:idata, "Reminder"],
[:end_tag], [:start_tag, "body"], [:idata, "Don't"],
[:idata, " "], [:idata, "forget"], [:idata, " "],
[:idata, "me"], [:idata, " "], [:idata, "this"],
[:idata, " "], [:idata, "weekend!"], [:end_tag], [:end_tag]

And this is emitted in StreamParser:

[:encoding, "iso-8859-1"], [:start_tag, "note"],
[:start_tag, "to"], [:data, "Tove"], [:end_tag, "to"],
[:start_tag, "from"], [:data, "Jani"], [:end_tag, "from"],
[:start_tag, "heading"], [:data, "Reminder"],
[:end_tag, "heading"], [:start_tag, "body"],
[:data, "Don't forget me this weekend!"],
[:end_tag, "body"], [:end_tag, "note"]

Finally, TreeParser returns this:

#&lt;Tree: [#&lt;Tree:note [#&lt;Tree:to ["Tove"]&gt;,
                      #&lt;Tree:from ["Jani"]&gt;,
                      #&lt;Tree:heading ["Reminder"]&gt;,
         #&lt;Tree:body ["Don't forget me this weekend!"]&gt;]&gt;]&gt;

Building the API this way was a lot of fun, as each layer only does its job. And yes, you can pipeline the streaming APIs. :-)

RLML is definitely a niche markup language, but it’s very easy to implement (~280 LoC so far) and has a simple, nice, userfriendly syntax. (It’s also possible to be converted from/to XML, with the loss respective conversion of attribute data.)

Now, on with unit tests…

20jun2004 · nukumi.el

I finished nukumi.el today, which includes a major mode for writing nukumi blog entries. It works very nicely now as it

  • highlights header lines,
  • displays leading and trailing space,
  • generates new blog entries with partly filled fields
    (that is, Date, Encoding, Now-Playing.)
  • and calls nukumi on C-c C-c.

See it in action:

19jun2004 · New feeds

I have rewitten large parts of the feed generation for Nukumi.

As a side effect, I had to break the <id>s of the Atom feed. This is bad, but it had to be done — better sooner than later.

I apologize for the inconvenience.

BTW, next week, my old blog will vanish (Yeah, that can even happen to blogs which are not hosted by weblogs.com :P). Please update your links to http://kronavita.de/chris/blog.

18jun2004 · Verkehrserziehung

Am Montag haben wir also Verkehrserziehung…

Verkehrserziehung, was ist das?Keine Ahnung. Vielleicht verteilt die Polizei Kondome…

Schnauze, Fury!

Wir haben uns also ein paar Fragen ausgedacht:

Mit wie vielen Joints darf man noch am Steuer stehen?

Darf ich die Stützräder von meinem Fahrrad wegmachen, wenn ich 16 bin?

Darf man im Kreisverkehr abkürzen?

Heißt “30-Zone” dass man schneller als 30 oder langsamer fahren soll?

Darf man im Kreisverkehr zelten?

Brauche ich einen Tacho um mit dem Fahrrad auf der Autobahn zu fahren?

Am Handy telefonieren darf man ja nicht. Ist SMSen ok?

Wo soll man die Punkte aus Flensburg an der Frontscheibe hinkleben?

Darf ich das Tempolimit übertreten, wenn ich einen Rot-Kreuz-Wagen überhole?

Darf man rückwärts gegen die Einbahnstraße fahren? [Soll in England erlaubt sein!]

Wie hoch ist die Strahlenbelastung durch Radarkontrollen? Meine Mutter macht sich sorgen.

Darf man die Nagelkette behalten, wenn man drübergefahren ist?

Gilt “rechts vor links” auch in der Politik?

Darf man Ozon-Fahrverbot fahren, wenn man die Abgase nach innen leitet?

Die Promille-Untergrenze liegt ja bei 0.5. Gibt es auch eine Übergrenze?

Gilt die Leiche im Leichenwagen als Passagier?

Wird Heizöl immernoch gefärbt? Schadet es dem Motor?

Gibt es Begrenzungen für die Vertikalgeschwindigkeit?

Muss man als Fußgänger eine Strafe zahlen, wenn man angefahren wird und schneller als 100km/h flieht?

Wie viele Kalorien hat ein Strafzettel?

Vielleicht wäre schulfrei für unsere Klasse besser gewesen… :-)

Meine Mutter hat mit ihrer Mutter Kontakt.Lesbe!

16jun2004 · We need more Why-Tos

The writing style of a Why-To is a lot different of a How-To.

While a How-To tries to make you quickly reach your goal, therefore being short, terse and often not very in-depth, a Why-To actually tells you why to do the stuff explained, and why it’s best. This is amazingly more fun to read and very instructive.

An example of a recent Why-To would be “The Art of Unix Programming” by ESR. It gives the probably most complete insight into the fundamentals of Unix and why they did the stuff that way.

Another really good example in case of Unix would be “The Unix Programming Environment” by Kernighan and Pike, which does the step from a very basic Unix command line introduction to a full-fledged C, Lex and Yacc using calculator, hoc. In between, shell scripts are extensively covered and a simple version control system is implemented.

It is, as said, a really great book, but unfortunately outdated and a lot (esp. of the arbitrary limits and “small” bugs of the tools) isn’t true anymore in a modern GNU environment.

I’d really like to see an introduction to GNU (and other open-source Unixes) written in that style of instructiveness.

Why’s Poignant Guide would probably be a very nice example of a Ruby why-to, and that with a special sense of humor. :-)

A great comment by Martin DeMello on ruby-talk, inside a long, unneeded thread on userface simplicity and commandlines:

The transition to Nukumi is mostly done, and the new address of this blog will be

The old blog will probably stay updated for a week or so, until my Nukumi workflow works for daily blogging.

RSS and Atom feeds are still a bit clumsy, but this will get fixed. (Will have to break <guid> and <id> :-(.)

07jun2004 · Petals around the Rose

I have been doing the game of the Petals around the Rose today. I need to admit that I needed a damn long time to get to such an easy solution. :-)

You can learn about the game at the Fraternity of Petals Around the Rose. Read that now, and try it.

Remember, the important stuff is:

The name of the game is Petals Around the Rose, and that name is significant. Newcomers to the game can be told that much. They can also be told that every answ er is zero or an even number. They can also be told the answer for every throw of the dice that are used in the game. And that’s all the information they get.

As soon as I had found the solution, of course I quickly implemented it in Ruby:

eval "ZGljZSA9ICgxLi42KS5tYXAgeyByYW5kKDYpKzEgfQpwZXRhbHMgPSB
kaWNlLmluamVjdCgwKSB7IHxhLCBifCBhICsgKGIlMiA9PSAwID8gMCA6IGIt
MSkgfQpwdXRzICJgUGV0YWxzIGFyb3VuZCB0aGUgUm9zZScgb2YgI3tkaWNlL
mpvaW4gJyAnfTogI3twZXRhbHN9Igo=".delete("\n").unpack("m*")[0]

It has been scrambled, because you shouldn’t read now how it works. Getting it on your own is the most important part of the game. (Of course, if you did it, go ahead and read the code. Stop! First solve the puzzle! (I know my readers… :-))

Some example output (I don’t think you can get it my just reading the numbers. You need to imagine dices.):

`Petals around the Rose' of 3 5 4 1 5 1: 10
`Petals around the Rose' of 4 4 3 3 6 4: 4
`Petals around the Rose' of 4 1 6 6 1 5: 4
`Petals around the Rose' of 5 2 5 1 5 5: 16
`Petals around the Rose' of 4 6 4 2 2 1: 0
`Petals around the Rose' of 4 1 2 1 1 3: 2

It’s really a great puzzle, so easy but so distracting… When you have found out how it works, you can punch yourself in the face. :-)

06jun2004 · Nukumi reloaded

After being back from holidays (more about that soon), I did some more hacking on Nukumi, and will be going to convert this blog to it, probably this week (though I still have some quite important tests I should learn for…).

I have been object-orientifying big parts of Nukumi; it’s very rubyish now. I also put it under control of GNU Arch and really have to say that xtla kicks ass.

I also added a new layout, mono. It will probably be the default layout for Nukumi (with a different image). Have fun.
