Fix HTML5 range slider slide event

I was very annoyed, that there was no change event on the HTML5 range element. You only got an event on mouseup. So i decided to write a short fix:

$('input[type=range]').mousedown(function () {
  this.slide = true;
  this.lastValue = this.value;
}).mousemove(function () {
  // trigger only on mouse down and
  // when the value has changed
  if (this.slide && this.lastValue !== this.value) {
    this.lastValue = this.value;
    $(this).trigger('change');
  }
}).mouseup(function () {
  this.slide = false;
});

Java HTML Parser

There is a very nice Java Library for parsing HTML with Java called jsoup.

I used it for Web Data Extraction and because of the nice JQuery-like API, it worked really well 🙂

Subclipse and Ubuntu

Subclipse will need the JavaHL Library so you have to install libsvn-java. The latest version of libsvn is 1.6.x but not compatible with the latest version of subclipse 😐
Solution 1
use subclipse 1.6
Solution 2
use subclipse 1.8 and update the libsvn. Dominik Stadler has the latest packages in his PPA https://launchpad.net/~dominik-stadler/+archive/ppa

Scrolling with jQuery

Scroll directly
$("html").attr({ scrollTop: $(document).height() });
$("html").attr({ scrollTop: 0 });

Scroll animation
$("html").animate({ scrollTop: $(document).height() }, 800);
$("html").animate({ scrollTop: 0 }, 800);

Tokenizer for Linux Shell (cut2)

About a year ago, i coded a little command line tool to tokenize data from a file or stdin and print each token as new line to stdout. Now you can use grep, sort or cut to manipulate the data further. As delimiter you can use any string you want and it will be left out in the result.

Sourcecode

After make copy the cut2 binary to /usr/bin/ and you can use it like every other command line tool.

Usage: cut2 -d DELIM [- | filename]

Have fun 🙂

update: improved code now available at github

Install Tomcat6 on Ubuntu to be used with Eclipse

sudo ln -s /var/lib/tomcat6/conf conf
sudo ln -s /etc/tomcat6/policy.d/03catalina.policy conf/catalina.policy
sudo ln -s /var/log/tomcat6 log
sudo chmod -R 777 /usr/share/tomcat6/conf

Se up a Git server with gitosis

The instructions i used can be found at scie.nti.st.

If you use Debian or Ubuntu you can install git and gitosis like:
apt-get install git gitosis

Everything works fine but i could not check out the repo with another user because of this warning:
“git Warning: remote HEAD refers to nonexistent ref, unable to checkout”

Found the solution on stackoverlow:
just do git config push.default current at the original source and the clone/checkout works fine!

To configure git-daemon and export singel repositories, this tutorial might help!
