A audio noise filter in JavaScript speech / non-speech classifcation
A few days ago I have written a small post about Reading Web Audio API with JavaScript. But no matter how silent I am acting on my working place, my computer is always producing the following noise.
I will try to create a small lightweight noise spectrum estimation and elimination filter in JavaScript that is based on the research of Quantile based noise estimation for spectral subtraction and Wiener filtering.
Use TkInter without mainloop
I am building a small python program that is waiting for input from a bluetooth device. Depending on the input of

Web performance checking with sitespeed.io
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.

Prism - syntax highlighting for Magento templates
In the past I have written a few posts about email template directives for Magento 2.

- Magento 2 email template translator directives
- Magento 2 email template config directives
- Magento 2 email template template directives
- Magento 2 email template logic directives
- Magento 2 email template style directives
- Magento 2 email template layout directives
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.
Change theme-color via JavaScript

Dynamic or lazy blocks in a CMS page with Lesti_FPC
Simon Sprankel contacted me a few days ago. He is using Lesti_FPC for a customer and he had a block in a few CMS pages. This block has to be dynamic or lazy. I have answered this tricky question a few times via email, but together we have found a good solution that I would like to present in this post.
Android chrome tab color

checked the HTML source of the website and found the responsible meta tag.
