Compress PNG

Yes, png image files can be compressed and make website load times shorter. I have been testing several online tools and https://tinypng.com/ had done a great job so far. Saved me almost 50% while keeping full transparency and good image quality.

This post is my way of thanking them for the service!

Bash Infinite Loop raspberry pi

We are using a raspberry pi (with raspbian) to run a video file in a loop at www.dokodemoterebi.com, but this should work with any linux version.

Creating an infinite loop is very simple the following code will do the trick:

while true; do omxplayer /home/pi/myvideo.mp4; done

If you want it to run at start up, edit /etc/init.d/rc.local and copy the code above at the end of rc.local

Now you only need to power the pi and the video will run in an endless loop, log in or any input from the user is not necessary. Be careful as you will be locked out if you do this. If you need to change something in the future you can plug the disk into another linux machine or use ssh.

speech jammer application

Did you ever want to silent someone? Then this is your tool. After japanese researchers invented the speech jammer, it did not take long for the smartphone app to pop out.

It must be fun, but I am not sure the phone speakers are strong enough, probably you need bigger speakers for this to work.
