It would been even better if it would be made an open source project…but who knows :)

Anyway…it can be downloaded here

I started this week to play around with it and I can assure you it’s fun.
Implementing a Scrollarea gave some problems for me tho.
(I admit, has a lot to do with my JS n00bness…but hey…)

If you you update the content of your scrollarea, don’t forget to refresh it…

example:

if (logstatus == 0) {
		loginhoud = logcall.outputString;
		content.innerHTML = loginhoud;
		document.getElementById("scrollArea").object.refresh();
	}
	else {
		content.innerHTML = "Problem fetching server data...";
	}

I think this is missing in the documentation…(yup, reporting it to Apple as well).

When making a POST request with XMLHttprequest and Safari(v2.0.4), always generate some content for the browser.

If not, the status will always be undefined.
example:

if (!$mysqli->query($insert)) {
  trigger_error("error writing data: ".$insert);
  exit;
}
else {
  echo "0";
}

This costed me some hours pulling my hair….
The following javascript works like a charm when you return a “0″ at the end of the php file called with POST. If you don’t return anything, Safari will decide that the HTTP headers are undefined and thus call the error handler.

KwAjax.ContentLoader.onReadyState=function(){
  var req=this.req;
  var ready=req.readyState;
  if (ready==KwAjax.READY_STATE_COMPLETE){
      var httpStatus=req.status;
      if (httpStatus == 200 || httpStatus == 0) {
        this.onload.call(this);
      }
      else {
        this.onerror.call(this);
      }
  }
}

I was one of the early (I think my 1st installed OS X version was developer release 4) adapters of OS X. And I very rarely thought back of OS 9/8/7/6. All the new thrills of the new OS made you forget about the good things of the classic OS’s.

This blogentry however sumarizes the most missed features of the old classic OS.

I personally miss feature #6. Tabbed folders the most.

But…A microsoft developer has the best excuse ever:

“If you are slow (or lazy) in your development, you never can be called a copycat”
Or, like he puts it:

Naturally, some Macintosh users will claim that this is like “Dashboard”. And indeed there are similarities here. But Microsoft has been working on Avalon a lot longer than Apple was working on Dashboard. And Avalon Express applications are designed to be very secure from day 1.

The quote above was taken from this website

The difference between priviliged useraccount and a “jailed” useraccount is a dot in the path of the home directory, for example: “/Users/./username”.

Being a little bit under stress and having not very much time, I couldn’t recall how to do that with OS X serveradmin.
Very frustrating. Googling and digging through the manuals didn’t give the answer where I was looking for.
Am I the only one who prefers the plain old /etc/passwd above netinfo?

But…today I recalled how I did it before.
And it’s so simple….(after mucking around with obscure CLI commands like nicl and serversetup)

Being used to PHP, it took some frustrating tries with javascript, but some hours later I was looking at my first widget.
It basically uses Curl to fetch PHP generated content over a HTTPS connection.
Shown are the last five lines of a access-log from a webapplication.
It works like a charm and refreshes every time dashboard shows up, or with the command+r keycombo.

If Tiger is released and the NDA is lifted, I’ll probably post the widget for download…untill then, some screenshots:

the front, some content blurred for privacy reasons

and the backside, i simply love the animation :)

But running php 4.3.6 and mysql 4.0.20 was getting…unwise.

Upgrading PHP is easy, with the (imho) great installer of entropy.ch.

installer -verboseR -pkg ~/php-4.3.10.pkg -target /

Don’t forget afterwards to restore your httpd.conf and to edit /usr/local/php/httpd.conf.php to add:

AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
AddType application/x-httpd-php-source .phps


MySQL is somewhat more tricky.
The version supplied by Apple is well…historic.
I like to compile MySQL from source (esp. because that takes 8,5 minute on my Xserve :) and install it to /usr/local/mysql-(version).
After that I create a symlink from /usr/local/mysql-(version) to /usr/local/mysql.
Take some care replacing the apple supplied mysql-binaries with symlinks to the up2date /usr/local/mysql/bin/ counterparts.
After this, upgrading mysql from source is painless.

The most recent upgrade:

# cd /usr/local/src
# gnutar -xzvf mysql-4.1.10a.tar.gz
# cd mysql-4.1.10a
# ./configure --with-openssl \
--prefix=/usr/local/mysql-4.1.10_a \
--localstatedir=/usr/local/mysql-4.1.10_a/data\
--mandir=/usr/local/share/man/\
--with-mysqld-user=mysql
# make
# make install
# cd /usr/local/
# mysqladmin -u root -p shutdown
# cp -R mysql/data mysql-4.1.10_a/data
# chown -r mysql:wheel mysql-4.1.10_a/data
# ln -s /usr/local/mysql-4.1.10_a /usr/local/mysql
# mysqld_safe &


That’s all. If something goes wrong, just restore the symlink to the “old” mysql-(version) and you’re safe.
Be aware of the new password hashing mysql uses from 4.1.1 of. I used the –old-password switch untill I’ve upgraded all my clients.
