I made a post about
Magento dependencies in 2013
with a small visualization graph. It is not that easy to do the same with Magento 2, but luckily I have found

chord diagrams out of a
composer.json and a
composer.lock with the help of
D3. I would like to show you the result.
I made a small post about
Inexact rounding up or down with decimal digits.
But it is also possible to run into the same bug when rounding floating point numbers to the next number with
restricted decimal digits. A really common example is the price calculation. You have the price
for example and the tax is maybe 19%. The resulting price with tax would be
2.3681. So you will
need to round the price with two decimal digits to
The most D3 examples that I can find are not responsive embedded SVG. I guess the main reason for that is not to confuse the reader of a tutorial with stuff outside of D3. With the help of How to Scale SVG from Amelia Bellamy-Royds I would like to show on a minimal D3 example how to make the resulting SVG responsive.

Node.js has changed this assumption.
I like to use Prism on my blog for syntax highlighting. Today I just want to test something like prototype for web text editor with Prism syntax highlighting. I know there are also working web text editors like CodeMirror for example, but as mentioned this post more a feasibility study.
I just want to check how the localStorage of a browser behaves over many tabs.
I am a little bit interested in the possibilities of reading audio input from the web browser. So I have written a small audio noise filter based on frame wise speech / non-speech classifcation a few days ago. This filter was based on the research of the paper Quantile based noise estimation for spectral subtraction and Wiener filtering. The paper contains also an other approach, a quantile based noise spectrum estimation.
A small tool to beautify or minify JSON data.
Sometimes tools are that awesome that you just want to spread the word. I guess I should do that more often. One fantastic tool is sitespeed.io. Sitespeed.io is a set of open source tools that will help you to analyze your website and gives you helpful advices to make your website faster.
I have read Visualizations with Web Audio API and just wanted to check on my own if I can build a small working example that can read the audio input from the Web Audio API.
I have started development of a
code folding plugin
for Prism syntax highlighting. The
by Lea Verou
showed me that the
summary tags combined with the
Keep markup plugin are a
more comfortable solution.
In the past I have written a few posts about email template directives for Magento 2.
I like to use Prism as syntax highlighter for my blog. So I have created a small grammer for Magento templates that are used for emails and for the CMS system.
A few days ago I have found
Android chrome tab color
and today I wanted to know if it can make sense to change the
sure if the chrome browser will update the tab color.
I am using Prism on my blog for my syntax highlighting and I am very happy and thankful about it. Sometimes I wanted to show the users of my blog a specific function of a class, but without decoupling the function from the class. So I needed something like a Prism plugin that can hide specific lines of the code in a foldable area.
I started my first Prism plugin. Prism uses hooks or in other software often called events to get simple plugin architecture. It is often a good idea to get an overview about all available hooks that Prism runs without any plugins. I will show in this post a small list with some explainations.
One more common tool that is fun to write and that I use pretty offen. A tool that converts timestamp to date.
It's fun to write small simple tools in the evening to come down. Here a tool to escape HTML as you can find it on every other HTML lerning website. It will replace the following characters with the right entities.
This is a small demo that shows how broilerjs is picking a color from an image by click. This example is a little bit different from the demos in the repository on Github, cause it is loaded with RequireJS to ensure it does not conflict with other jQuery versions on my blog. Just click a color in the rainbow image.
A few days ago, I bought me an ebook reader. I need a smart solution for the 2 hours in the subway each day. I just want to learn new frameworks or any other computer things. It was clear, the reader should at first support epub format. My choice was the kobo and I'm happy with that. But were did I get my ebooks from. Sure there are a lot of (free) ebooks in the web. But I want to support the authors and I can't write a critic review of a book I never paid for. Yes, I want to pay for my books, but I will never download books with DRM and install me any Adobe shit. It's very funny, many publisher have there own books without DRM and the reseller with DRM. But there are two publisher I did like very much in the last days. The first one is leanpub.com. You get good and also very bad books for mostly 10 to 20$ in all formats without DRM. A big disadvantage and also a advantage, the author can publish the book in a nonfinished status and you never know if it will be finished. The second Publisher is packtpub.com, a good known publisher from the old paper times. I like there instant books. Just 10$ and you get a more detailed tutorial I would say. And today I would like to say a little bit about Backbone.js Application Development from Thomas Hunter II.
