Astrill VPN (Client) App for Android 5+ (Lollipop)

I have found out that after my Smartphone updated to Android 5.0.1, the Astrill VPN app no longer works. It keeps returning an error message that says “No process running.”

I wrote an email to Astrill customer support, and they rely with a beta version of the app which worked fine in my Nexus 5, Android 5.1 system.

You can give it try from following link:

Counterintuitive Mac OS X Series 1: How to Completely Delete VPN.

Mac OS X is a very awesome operating system. But sometimes it just is not as intuitive as what it appears to be. For example,

Do you know how to delete VPN connections completely?

You might want to try something in “System Preferences -> Network” Settings. But you will soon discover that the button for removal is greyed out, and you cannot press it.

Some in apple support community suggested following ways to remove them. If you have rather complicated VPN connection names, you’d better rename them before you delete them one by one using the command. (You can rename them in Network preference page to rename it.)

It is kind of working, except that it failed to show you how to remove one last VPN connection. The command he suggested cannot remove last one.

In order to delete entire VPN completely, you need to remove Profiles generated by installing VPN services. If you open up “System Preferences”, you will see a “Profiles” icon. Get in and delete whatever profiles associated with the VPN which you would like to delete, then VPN will be gone. You will not even need the aforementioned method.

How to delete multiple articles at once at Kindle digital library

For some people, kindle has become more than an option, I use it daily to read articles, especially longer ones. With Amazon-provided “send to Kindle” extension in Chrome browser, sending documents to Kindle devices has become very useful.


But Kindle digital library has a very poor management function, while you can delete one single article, but you cannot delete several articles at once. That is why you have gone a long way to here.

In Chrome browser, get to the page where you the list of documents you want to delete from Kindle digital library, press “ctrl + shit + j”, a developer’s tool will pop-up. Select the console tab, and paste following lines of code, and press enter.


javascript:(function(){ var v = new RegExp("PersonalDocuments"); if (!v.test(document.URL)) { return false; } {a=document.getElementsByClassName('rowBodyCollapsed');for(var i = 0; i<a.length; i++){Fion.deleteItem('deleteItem_'+a[i].getAttribute('asin'));};return; }})();

Then you will see following screen that shows deleting action.
