None software tips for traveling
I always pack a power strip when i travel, hotels usually do not have enough outlets and if you are in a country that use some other standard it's even more important.
Sometimes i also pack a HDMI-cable or a Chromecast so you can use the TV in the hotell to watch your own stuff. I actually not used it so much but when you need it you really miss it.
And yeah, if you do not yet have a powerbank, come on?
