Compile faster throught a RAM disk

Compile programs takes a long time.
Do you have an SSD and it takes more time than with your old HDD? A good solution is create a RAM disk and compile on them.
First, you need to create a disk on your RAM (I chose 1Gb size)

sudo mkdir /mnt/tmpfs
sudo mount -o size=1G -t tmpfs none /mnt/tmpfs

Now, for test the speed, procced to create a file on it with dd:

dd if=/dev/zero of=file bs=1M count=100

On Ram disk (1.8 GB/s):



On SSD disk (172 MB/s):



It's a great difference!
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 ...
