How to speed up videos

Some weeks ago I was browsing my YouTube Watch Later lists and thinking: There is so much good quality video, I wish I could watch it faster to see more of it. All these Screencasts, Comedy, TechTalks, Conference Presentations … so I googled just for fun. Video Speed Controller I found out this is an issue, I’m not alone with. Fortunately the developer Ilya Grigorik, working at Google, has created a Google Chrome extension, which does exactly this: Speeding up HTML5 videos.

Martial Artist

I love martial arts, especially the Japanese. I practised Shotokan Karate for seven years and then began training Bujinkan Budo Taijutsu.

In Bujinkan we train nine different schools: six Samurai and three Ninja schools, the oldest of these school is nearly 1398 years old and the traditions where given from master to scholar for generations.

These martial arts aren’t sports, but highly efficient fighting systems, proven on the battlefields of ancient Japan.

I run a website on this topic for more than 17 years. I collected knowledge about the history, arts, tools, weapons, philosophy and life of the Ninja.

I am an Introvert (Meyer-Briggs personality type: INTJ – The Architect). Introverts think differently, our brain processes information in a different way than Extraverts, who get energy by social interaction with other people. Introverts loose their energy and need time to refill.

I love books, to be precise I love paper books. I can not imagine a living room without shelves of books.

Most likly I inherited this passion from my grandfather, who owned over 4000 books. My books count roughly a 1000. I buy books ahead and my desks are always stuffed with unread books. I like classics, books about philosophy, martial arts, art & desgin, architecture, typography and novels.

Work-related books I read mostly digital, because they get old too fast and don’t look nice in most cases.
