Internal hackaton at trivago

Date posted: November 19, 2014

trivago hackaton
One more night before we are going to start the internal hackaton at trivago. The topic of my hackaton group will be spider detection”. We will have a lot of data in log files. And my part of the project will be visualizing this data. I will dive into AngularJS and create some controllers, directives etc. for that. I am excited and looking forward to work together with the back-end developers.

For the project I used a couple of javascript libraries

the front-end prototype was working. but the pushed (json) data was not. So in the end we didn’t had a working prototype to show during the end presentation. This was a bit disappointed for me.

The first article I am going to read: http://davidwalsh.name/svg-animation.

I have to examples where I have just save vector files in Illustrator CS6 as .svg files. I have copy and paste the svg code into html code and see here the results:
svg trivago logo
svg trivago icon (velocity.js)

Here under a good example of the a range function I found on velocity

function r(min, max){
return Math.floor(Math.random()* (max-min +1))+ min;
}

HTML5 experimenting with the CANVAS element

Date posted: October 28, 2014

Here is an old experiment I found. I have made two sliders with images of my former Océ Design colleagues. One slider works with the input element with attribute type=”range” and the other slider is based on mouseover events. slider. I haven’t write the javascript code myself. If I find the source I will give the credits to the coder here.

Another site I need to look into: canvassing.

This is soooooo awesome: KEITH PETERS IS CREATING.

here are some experiments

the next step on which I will be focussing: sprite animation

Single html css file with animation

Date posted: October 27, 2014

To explore the possibilities what kind of animations only can be done by HTML and CSS. I have created this file single_file_animation.html I learned about the prefixes again. One good tip: animation-fill-mode. Nowadays there are also a lot of online CSS animation tools. One of the first results in google gave me this link: www.css3maker.com/. Really easy, define the animation and copy and paste the code. Next challenges will be events and combining multiple animations to an element.

Update: I found this link today: css-sprite-sheet-animations-steps.

I have created this file: css sprite animation
