Uninstall manually a Chrome extension

It can sometimes happen that an extension doesn’t want to be uninstalled with the steps provided by Google Chrome Support (to be tried first): https://support.google.com/chrome/answer/113907?hl=en.

Don’t worry, there’s a workaround available to delete definitely and manually this extension. Here are the steps:

  • Type about:extensions in the address bar and click on Developer Mode in the top-right hand corner
  • You will so find a ID line below any extension name. Copy this extension ID in a external text editor for example (you will need it several times later).
  • Right now, close entirely Chrome
  • Open Windows Start Menu and type the following line in the search box (or in the Execute menu):
    %LOCALAPPDATA%\Google\Chrome\User Data\Default\Extensions
  • In the explorer which has just opened, delete the folder with the ID matching the ID you have previously retrieved.
  • With the same steps, now access to this folder:
    %LOCALAPPDATA%\Google\Chrome\User Data\Default\Local Storage
  • In this folder, check if there is a file with a name such like chrome-extension_ID_0.localstorage (replace the ID value with the good one from your extension). If there is, delete it also.
  • Finally, one last step to be sure that this extension won’t re-install by itself automatically, you can check by typing regedit in the search bar of your Start Menu and then find the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallForcelist. Check that there is no entry containing the extension ID.
  • If there is, delete it ; else, everything is good !
  • You can now restart Chrome, and everything should run smoothly and fine !

Here it is, the extension doesn’t exist anymore on your PC ! (Don’t worry, you will be able to re-install it later if you want).

Install FTP server – PureFTPd

You want to set up an FTP server on your Linux installation ?

Here are the main steps you can use to set up very quickly a reliable and secure server under BSD licence : Pure-FTPd. The commands used in this tutorial are the commands available under Ubuntu Server and can so be different depending on the distribution you are using, especially on the packages installation.

Package installation :

sudo apt-get install pure-ftpd pure-ftpd-common

Group ftpgroup creation:

sudo groupadd ftpgroup

User ftpuser creation (linux user):

sudo useradd -g ftpgroup -d /dev/null -s /usr/sbin/nologin ftpuser

We can now create the user myuser (FTP user):

sudo pure-pw useradd myuser -u ftpuser -g ftpgroup -d /var/www/

Les options sont les suivantes :

  • -u uid
  • -g gid
  • -d user home

If you want to change the user password, just use the following command-line:

sudo pure-pw passwd myuser

Any time you perform a change or a creation of any user, you will need to re-generate the users database:

sudo pure-pw mkdb

Then you can activate the authentication linked to Pure-FTPd and restart the server:

sudo ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/50pure
sudo /etc/init.d/pure-ftpd restart

For a complete documentation, let’s go to the official PureFTPd website.

Activate developer options on your Android Device

Since Android 4.0, the developer options have disappeared from Android settings.

Actually, they have not really “disappeared”, they have just been hidden to avoid to display them for some users who would not have any usefulness in it and who could be afraid to do an error.

To enable them again, the steps to follow are really simple:

  1. Go in the General settings of Android
  2. Under System section, open the About Phone menu
  3. Tap 7 times on the Build Number (you will see a nice message displayed)
  4. The developer options are now unlocked

You can now use the developer options and use them for development and perform some applications debugging. Enjoy 😉 !
