Old way most of us are used to is not working with underlying operating systems that use systemd. After trying a lot of things with ntpd and ntpdate I found out that correct way to force sync the clock is:
timedatectl set-ntp true
128GB Samsung Micro SDXC EVO+ works on Sony Xperia Z2 LTE Tablet
I used to have 64GB micro SDXC card in my Xperia Z2 LTE tablet, but space became inadequate so I started to think about upgrading it. I needed more storage but according to GSMArena this tablet could handle up to 64GB. I did some research and saw that there are reports of users with 128GB cards.
I decided to test it since I really needed more space. In the past I was really satisfied with Samsung EVO+ sd cards 32/64GB capacity so I decided to try 128GB one from Samsung. Continue reading “128GB Samsung Micro SDXC EVO+ works on Sony Xperia Z2 LTE Tablet”

To format my USB sticks that I use following set of commands:

Pine64 looked interesting and promising since they raised $1.7M on Kickstarter offered 3 different variants for affordable price.
Allwinner is awful with their open source support so you will not be using this device for your next media center since Kodi will not work, but since it has 2GB RAM and 1Gb Ethernet it seems perfect fit for a small home server.

OrangePi poor replacement for the real Raspberry Pi
I was intrigued with low price of Orange Pi PC on GearBest site and since I had a lot of unused points I decided to order one even though I did not really need it. For a few bucks you get quad core CPU, 1GB of RAM, Ethernet all the bells and whistles as Raspberry Pi for third of the price.
What could go wrong? Well it seems for this price you get what you paid for a third of quality manufacturing. As soon as I opened my box I noticed that the board is slightly bent as you can see on the picture here: Continue reading “OrangePi poor replacement for the real Raspberry Pi”
