How to run Matlab without root permissions

If you have issues with Matlab to run commands without root, probably you will see this:

INFO: READ:  OnSendHeadersMessage{type=OnSendHeaders, uid=557, browserContextId=0, requestId=57, url=https://localhost:31515/messageservice/async, method=POST, headers=Origin: https://localhost:31515

 X-Requested-With: XMLHttpRequest

}, SocketInfo{channelId=0, browserId=-1, channelType=Main}

To fix it, just add permissions to your user with:

sudo chown -R $USER:$USER /usr/local/MATLAB/R2018b

If you run Matlab again, you will see this:

at com.mathworks.mlwidgets.shortcuts.ShortcutUtils.getShortcutsFile(ShortcutUtils.java:703)
at com.mathworks.mlwidgets.shortcuts.ShortcutUtils.saveDocument(ShortcutUtils.java:2034)
at com.mathworks.mlwidgets.shortcuts.ShortcutUtils.createInitialFavorites(ShortcutUtils.java:322)
Cannot write to preference file "matlab.prf" in "/home/$USER/.matlab/R2018b".
Check file permissions.
The desktop configuration was not saved successfully

To fix it, just add permissions to your local matlab folder:

 sudo chown -R $USER /home/$USER/.matlab/R2018b/ 

Enjoy it!

To enable it just add the first line and add the controller argument to net variable like the second line: from mininet.node import OVSController net = Mininet(topo=topo,host=CPULimitedHost, link=TCLink,controller = OVSController) Now, you will get the following error: c0 Cannot find required executable ovs-controller. Please make sure that it is installed and available in your $PATH: (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin) ovs-controller is a legacy name.

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 ...
