How to install go 1.8 on Ubuntu 16.04

If install golang in Ubuntu 16.04 throught synaptic, you will install version 1.6 and maybe you will see the following problems:

cannot find package "golang.org/x/sync/errgroup" in any of:
/usr/lib/go-1.6/src/golang.org/x/sync/errgroup (from $GOROOT)
/src/golang.org/x/sync/errgroup (from $GOPATH)
exit status 1
exit status 1

To avoid it, is better install it from the source:

wget https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz
sudo tar -zxvf go1.8.linux-amd64.tar.gz -C /usr/local/
mkdir ~/go
echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
echo 'export GOPATH=$HOME/go' >> ~/.bashrc
echo 'export PATH=$PATH:$GOROOT/bin:$GOPATH/bin' >> ~/.bashrc
source ~/.bashrc

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode ...

Contiki 3.0 on XM1000

Image
In other post, I installer contiki 3.x on xm1000. Now, we going to install contiki 3.0 (the lastest version). First, you need to dowload the lastest code from github: git clone https://github.com/contiki-os/contiki.git Now we need to add xm1000 compatibility to our contiki. Thanks to DMI   for the xm1000 patch. Without it, you will see the following error: make: *** No rule to make target 'obj_xm1000/cc2420.o', needed by 'contiki-xm1000.a'.  Stop. I upgrade his patch with an app to access to the xm1000 sensors. Download it from https://drive.google.com/file/d/0B7NXiwmWq7jCb3ROSFZZSWliMnc/view?usp=sharing Now, extract it into contiki folder: tar xzvf xm1000.tar.gz cd xm1000 cp -R * $YOUR_CONTIKI_PATH Go to the apps folder and execute an script that I create to automate the process: cd $YOUR_CONTIKI_PATH/platform/xm1000/apps/sensors ./install.sh Enjoy it!
